They were in the rugged, forested terrain of the Hindu Kush near the border with Pakistan, in an area where they had never been before. Soon afterward, these well-trained, fit Americans felt overwhelmed by their exertion in trying to navigate the physical volume of those mountains. The only SEAL to survive the mission, Markus Luttrell, subsequently wrote in his book Lone Survivor that their training for mountain warfare in California had not prepared them for those mountains, where "the terrain was absolutely horrible." The mountain was "so steep" that in their first few hours it was "a goddamned miracle we didn't fall off and break our necks." 1 Tired and eventually discovered by locals, the SEALs were ambushed by combatants who knew the terrain and controlled the most favorable position in mountain warfare: the higher ground.

Soon afterward, these well-trained, fit Americans felt overwhelmed by their exertion in trying to navigate the physical volume of those mountains. The only SEAL to survive the mission, Markus Luttrell, subsequently wrote in his book Lone Survivor that their training for mountain warfare in California had not prepared them for those mountains, where \"the terrain was absolutely horrible.\" The mountain was \"so steep\" that in their first few hours it was \"a goddamned miracle we didn't fall off and break our necks.\" 1 Tired and eventually discovered by locals, the SEALs were ambushed by combatants who knew the terrain and controlled the most favorable position in mountain warfare: the higher ground.

However, it is still unknown if cropping using soil systems could be sustainable in a Martian greenhouse under a gravity of 0.38g. The most challenging aspects are linked to the gravity-induced soil water flow; because water is crucial in driving nutrient and oxygen transport in both liquid and gaseous phases, a gravitational acceleration lower than g = 9.806 m s À2 could lead to suffocation of microorganisms and roots, with concomitant emissions of toxic gases. The effect of Martian gravity on soil processes was investigated using a highly mechanistic model previously tested for terrestrial crops that couples soil hydraulics and nutrient biogeochemistry. Net leaching of NO À 3 solute, gaseous fluxes of NH 3 , CO 2 , N 2 O, NO and N 2 , depth concentrations of O 2 , CO 2 and dissolved organic carbon (DOC), and pH in the root zone were calculated for a bioregenerative cropping unit under gravitational acceleration of Earth and for its homologous on Mars, but under 0.38g. The two cropping units were treated with the same fertilizer type and rate, and with the same irrigation regime, but under different initial soil moisture content. Martian gravity reduced water and solute leaching by about 90% compared to Earth. This higher water holding capacity in soil under Martian gravity led to moisture content and nutrient concentrations that favoured the metabolism of various microbial functional groups, whose density increased by 5-10% on Mars as compared to Earth. Denitrification rates became substantially more important than on Earth and ultimately resulted in 60%, 200% and 1200% higher emissions of NO, N 2 O and N 2 gases, respectively. Similarly, O 2 and DOC were consumed more rapidly in the Martian soil and resulted in about 10% increase in CO 2 emissions. More generally, Martian cropping would require 90% less water for irrigation than on Earth, being therefore favourable for water recycling treatment; in addition, a substantially lower nutrient supply from external sources such as fertilizers would not compromise nutrient delivery to soil microorganisms, but would reduce the large N gas emissions observed in this study.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/76062847" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="7b6f3ce5dcb05671ccbf5fac852480e3" rel="nofollow" data-download="{"attachment_id":83747995,"asset_id":76062847,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/83747995/download_file?st=MTc0MDg3MzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="111880114" href="https://ucberkeley.academia.edu/CelinePallud">Celine Pallud</a><script data-card-contents-for-user="111880114" type="text/json">{"id":111880114,"first_name":"Celine","last_name":"Pallud","domain_name":"ucberkeley","page_name":"CelinePallud","display_name":"Celine Pallud","profile_url":"https://ucberkeley.academia.edu/CelinePallud?f_ri=79394","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_76062847 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="76062847"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 76062847, container: ".js-paper-rank-work_76062847", });

The Lasem fault is indicated in 3 zones, namely the Rembang zone, Randublatung depression zone and Semarang-Rembang depression zone. Lasem fault is a fault located in the Pati-Rembang area which is an active fault and is close to the Semarang area. This research uses the gravity method as a basic understanding. The data uses obtained through the TOPEX/POSEIDON website. The data obtained were 154 measurement points at coordinates 111000' BT (E)-111013' BT (E) and 6040' LS (S)-6050' LS (S). The results obtained on TOPEX/POSEIDON are data of latitude and longitude coordinates, elevation and free air anomaly correction values. After that, further correction is made in the form of bouguer correction and terrain correction so that the complete bouguer anomaly value is obtained. The complete bouguer anomaly data is analyzed by spectrum with the results of depth estimation for the anomaly. Then an upward continuation is carried out to separate regional anomalies and residual anomalies. After that the gradient analysis filter, eulerdeconvolution, 3D and 2D modeling are done. Gradient analysis filter in the form of first horizontal gradient with the results in the form of fault indications and second vertical derivatives to determine the type of fault that is strike-slip fault. Euler deconvolution is used to determine the estimated subsurface depth with yields of up to 5000 m below sea level. 3D modeling is carried out to see fault indications which result that faults can be seen from depths of 1200 m to 4000 m. 2D modeling results show the types of rocks in the form of claystone, sandstone, limestone, and andesite, respectively the rocks have a density of 2.21 gr/cm 3 , 2.35 gr/cm 3 , 2.55 gr/cm 3 and 2.6 gr/cm 3. Keywords-Lasem fault, gravity method, gradient analysis, euler analysis, 3D and 2D modeling.. I. INTRODUCTION The gravity method is one of the geophysical methods based on the measurement of small variations in a gravity field. The difference in small variations or deviations in the terrain from point to point above the surface of the earth, is caused by lateral variations [1][2]. The gravity method is a method that studies variations in the gravity field that occur by variations in the density of rock masses below the surface, so that the variation investigated is the difference in the gravity field from an observation point to another point [2][3]. The gravity method can be used in analyzing the presence of the lasem fault by looking for the density variable that is below the surface. Lasem Fault is a fault with the longest straightness, occupying a depression with axes trending southwest-northeast. In previous research which concluded that by doing inversion modeling from gravity data concluded that the Lasem fault lies in 3 zones, namely the Rembang zone, the Randublatung depression zone and the Semarang-Rembang depression zone. Then the inversion modeling results obtained are depression models in the south and north of the study area with a density in the range of values 2,1-2,8 gr/cm3 [4].</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/75296031" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="22ef494a537ad45c786413384087524c" rel="nofollow" data-download="{"attachment_id":83121726,"asset_id":75296031,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/83121726/download_file?st=MTc0MDg3MzQ2NSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="52803885" href="https://independent.academia.edu/cmuwaffaq">chabib muwaffaq</a><script data-card-contents-for-user="52803885" type="text/json">{"id":52803885,"first_name":"chabib","last_name":"muwaffaq","domain_name":"independent","page_name":"cmuwaffaq","display_name":"chabib muwaffaq","profile_url":"https://independent.academia.edu/cmuwaffaq?f_ri=79394","photo":"https://0.academia-photos.com/52803885/13948218/15000556/s65_chabib.muwaffaq.jpg"}</script></span></span></li><li class="js-paper-rank-work_75296031 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="75296031"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 75296031, container: ".js-paper-rank-work_75296031", });

This is accomplished with the implementation of a well-developed mapping between solutions of Ricci-Based Palatini theories of gravity and General Relativity.

conduction phenomena in electrical wires with impurity and the scattering events responsible for particle production during stochastic inflation and reheating implemented under a closed quantum mechanical system in early universe cosmology. In this connection, we also present a derivation of quantum corrected version of the Fokker-Planck equation without dissipation and its fourth order corrected analytical solution for the probability distribution profile responsible for studying the dynamical features of the particle creation events in the stochastic inflation and reheating stage of the universe. It is explicitly shown from our computation that quantum corrected Fokker-Planck equation describe the particle creation phenomena better for Dirac delta type of scatterer. In this connection, we additionally discuss Itô, Stratonovich prescription and the explicit role of finite temperature effective potential for solving the probability distribution profile. Furthermore, we extend our discussion of particle production phenomena to describe the quantum description of randomness involved in the dynamics. We also present computation to derive the expression for the measure of the stochastic non-linearity (randomness or chaos) arising in the stochastic inflation and reheating epoch of the universe, often described by Lyapunov Exponent. Apart from that, we quantify the quantum chaos arising in a closed system by a more strong measure, commonly known as Spectral Form Factor using the principles of random matrix theory (RMT). Additionally, we discuss the role of out of time order correlation function (OTOC) to describe quantum chaos in the present non-equilibrium field theoretic setup and its cona e-mails:</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/77018537" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="ce179538ec0c7e49567679eec7d3464b" rel="nofollow" data-download="{"attachment_id":84516584,"asset_id":77018537,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/84516584/download_file?st=MTc0MDg3MzQ2NSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="184632" href="https://sgtuniversity.academia.edu/SayantanChoudhury">Sayantan Choudhury</a><script data-card-contents-for-user="184632" type="text/json">{"id":184632,"first_name":"Sayantan","last_name":"Choudhury","domain_name":"sgtuniversity","page_name":"SayantanChoudhury","display_name":"Sayantan Choudhury","profile_url":"https://sgtuniversity.academia.edu/SayantanChoudhury?f_ri=79394","photo":"https://0.academia-photos.com/184632/45366/77994148/s65_sayantan.choudhury.png"}</script></span></span></li><li class="js-paper-rank-work_77018537 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="77018537"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 77018537, container: ".js-paper-rank-work_77018537", });

It is explicitly shown from our computation that quantum corrected Fokker-Planck equation describe the particle creation phenomena better for Dirac delta type of scatterer.

This force is validated here in General Relativity for an inhomogeneous radially symmetrical universe. It can be deduced from the solution of Einstein's equation with a cosmological constant. A pseudo-Schwarzschild "twin-potential" metric is considered, with two different potentials for the space and time dimensions. The expansion force results as a repulsive dual gravity. Negative masses are needed. The necessary mass repartitions are computed, in connection with the radial dynamics and the expansion rate's evolution. A linear model and a quadratic model are studied, connected with the observation representations of a universe in accelerated expansion. It is a first step towards a better representation of an inhomogeneous universe. The framework can be applied to deduce the universe mass repartition form the measured values of the expansion rate variation. Résumé J'ai proposé en 2016 une nouvelle force d'expansion pour expliquer les courbes de rotation plates des galaxies spirales dans une approche Newtonienne. Cette force est validée ici dans le cadre de la Relativité Générale pour un univers inhomogène à symétrie radiale.

This force is validated here in General Relativity for an inhomogeneous radially symmetrical universe. It can be deduced from the solution of Einstein's equation with a cosmological constant. A pseudo-Schwarzschild \"twin-potential\" metric is considered, with two different potentials for the space and time dimensions. The expansion force results as a repulsive dual gravity. Negative masses are needed. The necessary mass repartitions are computed, in connection with the radial dynamics and the expansion rate's evolution. A linear model and a quadratic model are studied, connected with the observation representations of a universe in accelerated expansion. It is a first step towards a better representation of an inhomogeneous universe. The framework can be applied to deduce the universe mass repartition form the measured values of the expansion rate variation.

In particular, the landing trajectory of MASCOT-2 is investigated and analyzed into detail during close-proximity operations at the binary asteroid 65803 Didymos. Design opportunities are investigated using a three-body approach to model the dynamical system in the close proximity of the asteroid couple. Landing requirements, applicable to the mission scenario under study, are presented and a suitable strategy is selected, by conveniently exploiting three-body dynamics. Uncertainties in release and touch down conditions are modeled and successful landing probability is assessed.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/35031235" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="2c59ea1c6b102e2f2dbbaeec536d563d" rel="nofollow" data-download="{"attachment_id":54893821,"asset_id":35031235,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/54893821/download_file?st=MTc0MDg3MzQ2NSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="17182308" href="https://polimi.academia.edu/FabioFerrari">Fabio Ferrari</a><script data-card-contents-for-user="17182308" type="text/json">{"id":17182308,"first_name":"Fabio","last_name":"Ferrari","domain_name":"polimi","page_name":"FabioFerrari","display_name":"Fabio Ferrari","profile_url":"https://polimi.academia.edu/FabioFerrari?f_ri=79394","photo":"https://0.academia-photos.com/17182308/5905833/17070912/s65_fabio.ferrari.jpg"}</script></span></span></li><li class="js-paper-rank-work_35031235 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="35031235"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 35031235, container: ".js-paper-rank-work_35031235", });

In particular, the landing trajectory of MASCOT-2 is investigated and analyzed into detail during close-proximity operations at the binary asteroid 65803 Didymos. Design opportunities are investigated using a three-body approach to model the dynamical system in the close proximity of the asteroid couple. Landing requirements, applicable to the mission scenario under study, are presented and a suitable strategy is selected, by conveniently exploiting three-body dynamics. Uncertainties in release and touch down conditions are modeled and successful landing probability is assessed.","downloadable_attachments":[{"id":54893821,"asset_id":35031235,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":17182308,"first_name":"Fabio","last_name":"Ferrari","domain_name":"polimi","page_name":"FabioFerrari","display_name":"Fabio Ferrari","profile_url":"https://polimi.academia.edu/FabioFerrari?f_ri=79394","photo":"https://0.academia-photos.com/17182308/5905833/17070912/s65_fabio.ferrari.jpg"}],"research_interests":[{"id":2453,"name":"Asteroids","url":"https://www.academia.edu/Documents/in/Asteroids?f_ri=79394","nofollow":true},{"id":79394,"name":"Gravity","url":"https://www.academia.edu/Documents/in/Gravity?f_ri=79394","nofollow":true},{"id":96054,"name":"Gravity Model","url":"https://www.academia.edu/Documents/in/Gravity_Model?f_ri=79394","nofollow":true},{"id":911616,"name":"Space Missions","url":"https://www.academia.edu/Documents/in/Space_Missions?f_ri=79394","nofollow":true}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_41360728" data-work_id="41360728" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/41360728/A_NEW_ENVIRONMENT_TO_SIMULATE_THE_DYNAMICS_IN_THE_CLOSE_PROXIMITY_OF_RUBBLE_PILE_ASTEROIDS">A NEW ENVIRONMENT TO SIMULATE THE DYNAMICS IN THE CLOSE PROXIMITY OF RUBBLE-PILE ASTEROIDS</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">This paper presents a new environment to simulate close-proximity dynamics around rubble-pile asteroids.

Exact solutions are given for several classes of f (R) theories in both R = constant and R = R(r).","downloadable_attachments":[{"id":45514441,"asset_id":13284330,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":32536896,"first_name":"Salvatore","last_name":"Capozziello","domain_name":"unina","page_name":"SalvatoreCapozziello","display_name":"Salvatore Capozziello","profile_url":"https://unina.academia.edu/SalvatoreCapozziello?f_ri=79394","photo":"https://0.academia-photos.com/32536896/10088512/11255624/s65_salvatore.capozziello.jpg"}],"research_interests":[{"id":3504,"name":"General Relativity","url":"https://www.academia.edu/Documents/in/General_Relativity?f_ri=79394","nofollow":true},{"id":79394,"name":"Gravity","url":"https://www.academia.edu/Documents/in/Gravity?f_ri=79394","nofollow":true},{"id":80414,"name":"Mathematical Sciences","url":"https://www.academia.edu/Documents/in/Mathematical_Sciences?f_ri=79394","nofollow":true},{"id":118428,"name":"Curvature","url":"https://www.academia.edu/Documents/in/Curvature?f_ri=79394","nofollow":true},{"id":118582,"name":"Physical sciences","url":"https://www.academia.edu/Documents/in/Physical_sciences?f_ri=79394"},{"id":181847,"name":"First-Order Logic","url":"https://www.academia.edu/Documents/in/First-Order_Logic?f_ri=79394"},{"id":456174,"name":"Spherical symmetry","url":"https://www.academia.edu/Documents/in/Spherical_symmetry?f_ri=79394"},{"id":891487,"name":"Gravity(classical and Quantum)","url":"https://www.academia.edu/Documents/in/Gravity_classical_and_Quantum_?f_ri=79394"},{"id":1402673,"name":"Perturbation","url":"https://www.academia.edu/Documents/in/Perturbation?f_ri=79394"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_40055128" data-work_id="40055128" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/40055128/On_the_Time_Variation_of_Fundamental_Constants">On the Time Variation of Fundamental Constants</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">We will define the mass of an electron in the context of Weinberg's empirical formula that relates the mass of a pion to fundamental physical constants, namely the gravitational and Planck constants, the speed of light in vacuum and the... <a class="more_link u-tcGrayDark u-linkUnstyled" data-container=".work_40055128" data-show=".complete" data-hide=".summarized" data-more-link-behavior="true" href="#">more</a></div><div class="complete hidden">We will define the mass of an electron in the context of Weinberg's empirical formula that relates the mass of a pion to fundamental physical constants, namely the gravitational and Planck constants, the speed of light in vacuum and the Hubble constant.

Our approach offers several ways to measure the speed of gravity (light) and checks existing assumptions about light (gravity) in new types of experiments. The speed of light is included in several well-known gravita-tional formulas. However, if we can measure this speed from gravitational phenomena alone, then is it the speed of light or the speed of gravity we are measuring? We think it is more than a mere coincidence that they are the same. In addition, even if it is not possible to draw strong conclusions now, our formulations support the view that there is a link between electromagnet-ism and gravity. This paper also shows that all major gravity phenomena can be predicted from only performing two to three light observations. There is no need for knowledge of Newton's gravitational constant G or the mass size to complete a series of major gravity predictions.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/39076501" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="9cb4ee860328af2f66e8f1cee3c7d00a" rel="nofollow" data-download="{"attachment_id":59192598,"asset_id":39076501,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/59192598/download_file?st=MTc0MDg3MzQ2NSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="94171111" href="https://independent.academia.edu/EspenHaug">Espen G A A R D E R Haug</a><script data-card-contents-for-user="94171111" type="text/json">{"id":94171111,"first_name":"Espen","last_name":"Haug","domain_name":"independent","page_name":"EspenHaug","display_name":"Espen G A A R D E R Haug","profile_url":"https://independent.academia.edu/EspenHaug?f_ri=79394","photo":"https://0.academia-photos.com/94171111/24231428/25026700/s65_espen.haug.png"}</script></span></span></li><li class="js-paper-rank-work_39076501 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="39076501"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 39076501, container: ".js-paper-rank-work_39076501", });

Our approach offers several ways to measure the speed of gravity (light) and checks existing assumptions about light (gravity) in new types of experiments. The speed of light is included in several well-known gravita-tional formulas. However, if we can measure this speed from gravitational phenomena alone, then is it the speed of light or the speed of gravity we are measuring? We think it is more than a mere coincidence that they are the same. In addition, even if it is not possible to draw strong conclusions now, our formulations support the view that there is a link between electromagnet-ism and gravity. This paper also shows that all major gravity phenomena can be predicted from only performing two to three light observations. There is no need for knowledge of Newton's gravitational constant G or the mass size to complete a series of major gravity predictions.","downloadable_attachments":[{"id":59192598,"asset_id":39076501,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":94171111,"first_name":"Espen","last_name":"Haug","domain_name":"independent","page_name":"EspenHaug","display_name":"Espen G A A R D E R Haug","profile_url":"https://independent.academia.edu/EspenHaug?f_ri=79394","photo":"https://0.academia-photos.com/94171111/24231428/25026700/s65_espen.haug.png"}],"research_interests":[{"id":79394,"name":"Gravity","url":"https://www.academia.edu/Documents/in/Gravity?f_ri=79394","nofollow":true},{"id":677240,"name":"Speed of Light","url":"https://www.academia.edu/Documents/in/Speed_of_Light?f_ri=79394","nofollow":true},{"id":1253944,"name":"Speed of Gravity","url":"https://www.academia.edu/Documents/in/Speed_of_Gravity?f_ri=79394","nofollow":true}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_69598778" data-work_id="69598778" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/69598778/Constraining_N_1_supergravity_inflationary_framework_with_non_minimal_K%C3%A4hler_operators">Constraining N = 1 supergravity inflationary framework with non-minimal Kähler operators</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">In this paper we will illustrate how to constrain unavoidable Kähler corrections for N = 1 supergravity (SUGRA) inflation from the recent Planck data.

The entire SUGRA inflationary framework can now be constrained from (i) the speed of sound, cs, and (ii) from the upper bound on the tensor to scalar ratio, r⋆. We will illustrate this by considering a heavy scalar degree of freedom at a scale, Ms, and a light inflationary field which is responsible for a slow-roll inflation.

The first is linear and uses a linear vehicle model. The remaining observers use an extended nonlinear model. The three nonlinear observers are: extended Luenberger observer, extended Kalman filter and sliding-mode observer. Modeling, model simplification, and observers are described, and an observability analysis is performed for the entire vehicle trajectory. The paper also deals with three different sets of sensors to see the impact of observers results. Comparison is first done by simulation on a valid vehicle simulator, and then observers are used on experimental data. Our study shows that observers are more accurate than simple models as regards unmeasurable variables such as sideslip angle and transversal forces. It also shows that speed of center of gravity is not an indispensable variable here.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/8447498" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="a36e55be31bb8eccd5949ed6a03b0357" rel="nofollow" data-download="{"attachment_id":48092752,"asset_id":8447498,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/48092752/download_file?st=MTc0MDg3MzQ2NSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="17164764" href="https://xlim.academia.edu/joannySTEPHANT">joanny STEPHANT</a><script data-card-contents-for-user="17164764" type="text/json">{"id":17164764,"first_name":"joanny","last_name":"STEPHANT","domain_name":"xlim","page_name":"joannySTEPHANT","display_name":"joanny STEPHANT","profile_url":"https://xlim.academia.edu/joannySTEPHANT?f_ri=79394","photo":"https://0.academia-photos.com/17164764/4730446/5455626/s65_joanny.stephant.jpg"}</script></span></span></li><li class="js-paper-rank-work_8447498 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="8447498"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 8447498, container: ".js-paper-rank-work_8447498", });

The first is linear and uses a linear vehicle model. The remaining observers use an extended nonlinear model. The three nonlinear observers are: extended Luenberger observer, extended Kalman filter and sliding-mode observer. Modeling, model simplification, and observers are described, and an observability analysis is performed for the entire vehicle trajectory. The paper also deals with three different sets of sensors to see the impact of observers results. Comparison is first done by simulation on a valid vehicle simulator, and then observers are used on experimental data. Our study shows that observers are more accurate than simple models as regards unmeasurable variables such as sideslip angle and transversal forces. It also shows that speed of center of gravity is not an indispensable variable here.","downloadable_attachments":[{"id":48092752,"asset_id":8447498,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":17164764,"first_name":"joanny","last_name":"STEPHANT","domain_name":"xlim","page_name":"joannySTEPHANT","display_name":"joanny STEPHANT","profile_url":"https://xlim.academia.edu/joannySTEPHANT?f_ri=79394","photo":"https://0.academia-photos.com/17164764/4730446/5455626/s65_joanny.stephant.jpg"}],"research_interests":[{"id":48,"name":"Engineering","url":"https://www.academia.edu/Documents/in/Engineering?f_ri=79394","nofollow":true},{"id":8050,"name":"Vehicle Dynamics","url":"https://www.academia.edu/Documents/in/Vehicle_Dynamics?f_ri=79394","nofollow":true},{"id":33252,"name":"State Estimation","url":"https://www.academia.edu/Documents/in/State_Estimation?f_ri=79394","nofollow":true},{"id":49146,"name":"Kalman Filter","url":"https://www.academia.edu/Documents/in/Kalman_Filter?f_ri=79394","nofollow":true},{"id":55405,"name":"Sensors","url":"https://www.academia.edu/Documents/in/Sensors?f_ri=79394"},{"id":73017,"name":"Nonlinear Systems","url":"https://www.academia.edu/Documents/in/Nonlinear_Systems?f_ri=79394"},{"id":79394,"name":"Gravity","url":"https://www.academia.edu/Documents/in/Gravity?f_ri=79394"},{"id":81790,"name":"Nonlinear Observer","url":"https://www.academia.edu/Documents/in/Nonlinear_Observer?f_ri=79394"},{"id":111966,"name":"Observability","url":"https://www.academia.edu/Documents/in/Observability?f_ri=79394"},{"id":196514,"name":"Center of Gravity","url":"https://www.academia.edu/Documents/in/Center_of_Gravity?f_ri=79394"},{"id":325035,"name":"Linear System","url":"https://www.academia.edu/Documents/in/Linear_System?f_ri=79394"},{"id":350706,"name":"Linear Systems","url":"https://www.academia.edu/Documents/in/Linear_Systems?f_ri=79394"},{"id":506858,"name":"Nonlinear system","url":"https://www.academia.edu/Documents/in/Nonlinear_system?f_ri=79394"},{"id":872410,"name":"Extended Kalman Filter","url":"https://www.academia.edu/Documents/in/Extended_Kalman_Filter?f_ri=79394"},{"id":882604,"name":"Nonlinear Model","url":"https://www.academia.edu/Documents/in/Nonlinear_Model?f_ri=79394"},{"id":912908,"name":"Noise Measurement","url":"https://www.academia.edu/Documents/in/Noise_Measurement?f_ri=79394"},{"id":1120502,"name":"Experimental Data","url":"https://www.academia.edu/Documents/in/Experimental_Data?f_ri=79394"},{"id":2005127,"name":"Sliding Mode Observer","url":"https://www.academia.edu/Documents/in/Sliding_Mode_Observer?f_ri=79394"},{"id":2260028,"name":"Model Simplification","url":"https://www.academia.edu/Documents/in/Model_Simplification?f_ri=79394"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_41612959" data-work_id="41612959" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/41612959/Renaissance_Concept_of_Gravitas">Renaissance Concept of Gravitas</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Traditionally, gravitas denotes the inner source of movement towards the centre of the universe.

EP is classified according to its local and global aspects. The local aspects of the EP include noncovariance of the energy-momentum pseudotensor (EMPT) of the gravitational field, non-uniqueness of the EMPT, asymmetry of EMPT and vanishing metric energy-momentum tensor. The global aspect of the EP relates to the lack of integral conservation laws due to the general difficulties in defining invariant integrals of tensors in non-Euclidean space. These difficulties are related to the lack of a precise definition of a reference frame in the GR. A reference frame is defined here as a differential manifold with an Affine connection. The resulting unique decomposition of the Levi-Civita connection into its Affine and nonmetric parts allows for a covariant definition of the gravitational energy-momentum tensor. It is pointed out that the invariance of the Lagrangian (or action functional) is a necessary but not sufficient condition to secure the covariance of the Lagrange-Euler field theory. A rigorous definition of the Lagrange Field Structure (LFS) on differential manifolds is proposed. A covariant generalization of the first Noether theorem for LFS is obtained. Different approaches to the EP are discussed.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/19021518" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="e1a372852a59ded8abf4bf8829d66fab" rel="nofollow" data-download="{"attachment_id":40386170,"asset_id":19021518,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/40386170/download_file?st=MTc0MDg3MzQ2NSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="38999594" href="https://ccny1-cuny.academia.edu/AlexanderPoltorak">Alexander Poltorak</a><script data-card-contents-for-user="38999594" type="text/json">{"id":38999594,"first_name":"Alexander","last_name":"Poltorak","domain_name":"ccny1-cuny","page_name":"AlexanderPoltorak","display_name":"Alexander Poltorak","profile_url":"https://ccny1-cuny.academia.edu/AlexanderPoltorak?f_ri=79394","photo":"https://0.academia-photos.com/38999594/10804710/12059565/s65_alexander.poltorak.jpg"}</script></span></span></li><li class="js-paper-rank-work_19021518 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="19021518"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 19021518, container: ".js-paper-rank-work_19021518", });

EP is classified according to its local and global aspects. The local aspects of the EP include noncovariance of the energy-momentum pseudotensor (EMPT) of the gravitational field, non-uniqueness of the EMPT, asymmetry of EMPT and vanishing metric energy-momentum tensor. The global aspect of the EP relates to the lack of integral conservation laws due to the general difficulties in defining invariant integrals of tensors in non-Euclidean space. These difficulties are related to the lack of a precise definition of a reference frame in the GR. A reference frame is defined here as a differential manifold with an Affine connection. The resulting unique decomposition of the Levi-Civita connection into its Affine and nonmetric parts allows for a covariant definition of the gravitational energy-momentum tensor. It is pointed out that the invariance of the Lagrangian (or action functional) is a necessary but not sufficient condition to secure the covariance of the Lagrange-Euler field theory. A rigorous definition of the Lagrange Field Structure (LFS) on differential manifolds is proposed. A covariant generalization of the first Noether theorem for LFS is obtained. Different approaches to the EP are discussed.","downloadable_attachments":[{"id":40386170,"asset_id":19021518,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":38999594,"first_name":"Alexander","last_name":"Poltorak","domain_name":"ccny1-cuny","page_name":"AlexanderPoltorak","display_name":"Alexander Poltorak","profile_url":"https://ccny1-cuny.academia.edu/AlexanderPoltorak?f_ri=79394","photo":"https://0.academia-photos.com/38999594/10804710/12059565/s65_alexander.poltorak.jpg"}],"research_interests":[{"id":333,"name":"Field Theory","url":"https://www.academia.edu/Documents/in/Field_Theory?f_ri=79394","nofollow":true},{"id":1246,"name":"Gravitation","url":"https://www.academia.edu/Documents/in/Gravitation?f_ri=79394","nofollow":true},{"id":3504,"name":"General Relativity","url":"https://www.academia.edu/Documents/in/General_Relativity?f_ri=79394","nofollow":true},{"id":49963,"name":"Gravity Equation","url":"https://www.academia.edu/Documents/in/Gravity_Equation?f_ri=79394","nofollow":true},{"id":66885,"name":"General Theory of Relativity","url":"https://www.academia.edu/Documents/in/General_Theory_of_Relativity?f_ri=79394"},{"id":79394,"name":"Gravity","url":"https://www.academia.edu/Documents/in/Gravity?f_ri=79394"},{"id":101328,"name":"Frames of Reference","url":"https://www.academia.edu/Documents/in/Frames_of_Reference?f_ri=79394"},{"id":396019,"name":"Reference frames","url":"https://www.academia.edu/Documents/in/Reference_frames?f_ri=79394"},{"id":536804,"name":"Euler Lagrange Equation","url":"https://www.academia.edu/Documents/in/Euler_Lagrange_Equation?f_ri=79394"},{"id":553567,"name":"Energy-Momentum Tensor","url":"https://www.academia.edu/Documents/in/Energy-Momentum_Tensor?f_ri=79394"},{"id":553570,"name":"Gravitational Field","url":"https://www.academia.edu/Documents/in/Gravitational_Field?f_ri=79394"},{"id":704980,"name":"Energy-Momentum Conservation","url":"https://www.academia.edu/Documents/in/Energy-Momentum_Conservation?f_ri=79394"},{"id":738478,"name":"Lagrange Function","url":"https://www.academia.edu/Documents/in/Lagrange_Function?f_ri=79394"},{"id":1465637,"name":"Nonmetricity","url":"https://www.academia.edu/Documents/in/Nonmetricity?f_ri=79394"},{"id":1465639,"name":"Affine Connection","url":"https://www.academia.edu/Documents/in/Affine_Connection?f_ri=79394"},{"id":1841094,"name":"Noether’s theorem","url":"https://www.academia.edu/Documents/in/Noether_s_theorem?f_ri=79394"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_44465159" data-work_id="44465159" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/44465159/Gravity_from_Newton_and_Einstein_to_Quantum_Gravity">Gravity, from Newton and Einstein to Quantum Gravity</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">In this research, I will try to give a simple, more general understanding of how gravity works.

This material comprises of steel hollow spheres and a solid aluminum alloy matrix. The energy absorption behavior of the material under static compression has been studied extensively. Experimental results show that CMF not only has a higher energy absorption capability than that of other commercially available metal foams produced from similar materials, but also possess a higher strength to density ratio. The microstructural analysis of the material was used to study and explain the formation of different phases at the aluminum-steel interface and their effect on the deformation behavior of the foam under compression. As the result of high strength and strain rates, the increase in energy absorption of the composite metal foam samples observed ranges over 30 times compared to that of 100% Al foams and over twice compared to that of 100% steel foams.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/30291953" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="a3a4d8a75515e4870016208a9c704512" rel="nofollow" data-download="{"attachment_id":50752344,"asset_id":30291953,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/50752344/download_file?st=MTc0MDg3MzQ2NSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="57529183" href="https://ncsu.academia.edu/AfsanehRabiei">Afsaneh Rabiei</a><script data-card-contents-for-user="57529183" type="text/json">{"id":57529183,"first_name":"Afsaneh","last_name":"Rabiei","domain_name":"ncsu","page_name":"AfsanehRabiei","display_name":"Afsaneh Rabiei","profile_url":"https://ncsu.academia.edu/AfsanehRabiei?f_ri=79394","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_30291953 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="30291953"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 30291953, container: ".js-paper-rank-work_30291953", });

This material comprises of steel hollow spheres and a solid aluminum alloy matrix. The energy absorption behavior of the material under static compression has been studied extensively. Experimental results show that CMF not only has a higher energy absorption capability than that of other commercially available metal foams produced from similar materials, but also possess a higher strength to density ratio. The microstructural analysis of the material was used to study and explain the formation of different phases at the aluminum-steel interface and their effect on the deformation behavior of the foam under compression. As the result of high strength and strain rates, the increase in energy absorption of the composite metal foam samples observed ranges over 30 times compared to that of 100% Al foams and over twice compared to that of 100% steel foams.","downloadable_attachments":[{"id":50752344,"asset_id":30291953,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":57529183,"first_name":"Afsaneh","last_name":"Rabiei","domain_name":"ncsu","page_name":"AfsanehRabiei","display_name":"Afsaneh Rabiei","profile_url":"https://ncsu.academia.edu/AfsanehRabiei?f_ri=79394","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":56,"name":"Materials Engineering","url":"https://www.academia.edu/Documents/in/Materials_Engineering?f_ri=79394","nofollow":true},{"id":60,"name":"Mechanical Engineering","url":"https://www.academia.edu/Documents/in/Mechanical_Engineering?f_ri=79394","nofollow":true},{"id":2161,"name":"Microstructure","url":"https://www.academia.edu/Documents/in/Microstructure?f_ri=79394","nofollow":true},{"id":10655,"name":"Scanning Electron Microscopy","url":"https://www.academia.edu/Documents/in/Scanning_Electron_Microscopy?f_ri=79394","nofollow":true},{"id":39606,"name":"Strain Rate","url":"https://www.academia.edu/Documents/in/Strain_Rate?f_ri=79394"},{"id":41010,"name":"Casting","url":"https://www.academia.edu/Documents/in/Casting?f_ri=79394"},{"id":79394,"name":"Gravity","url":"https://www.academia.edu/Documents/in/Gravity?f_ri=79394"},{"id":169323,"name":"Composite Material","url":"https://www.academia.edu/Documents/in/Composite_Material?f_ri=79394"},{"id":209515,"name":"Interface","url":"https://www.academia.edu/Documents/in/Interface?f_ri=79394"},{"id":426001,"name":"Metal Foam","url":"https://www.academia.edu/Documents/in/Metal_Foam?f_ri=79394"},{"id":473797,"name":"Microstructures","url":"https://www.academia.edu/Documents/in/Microstructures?f_ri=79394"},{"id":907382,"name":"Digital Image","url":"https://www.academia.edu/Documents/in/Digital_Image?f_ri=79394"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_52515985" data-work_id="52515985" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" rel="nofollow" href="https://www.academia.edu/52515985/A_gravimetric_quasi_geoid_evaluation_in_the_Northern_region_of_Algeria_using_EGM96_and_GPS_Levelling">A gravimetric quasi-geoid evaluation in the Northern region of Algeria using EGM96 and GPS/Levelling</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">The use of GPS for the estimation of orthometric heights in a given region, with the help of existing levelling data requires the determination of a local geoid and the bias between the local levelling and the one implicitly defined when... <a class="more_link u-tcGrayDark u-linkUnstyled" data-container=".work_52515985" data-show=".complete" data-hide=".summarized" data-more-link-behavior="true" href="#">more</a></div><div class="complete hidden">The use of GPS for the estimation of orthometric heights in a given region, with the help of existing levelling data requires the determination of a local geoid and the bias between the local levelling and the one implicitly defined when the geoid is calculated which is generally based on the gravity anomalies data.

This has affected the course of humanity and how society has prejudice towards either science or religion. Atheist scientists believe in what they know because they believe in reason and think that theists are unreasonable. The paper brings the problems facing humanity today between science, religion, and secularism within societies. The followers of each could be fanatics of their own group. The paper tries to reconcile the debate between atheists and theists, under the microscope of science. This study makes an analogy of G-d and gravity. It shows that the power of reason used by scientists to deduce gravity is the exact same reasoning that theists use to believe in G-d. The study goes beyond philosophical arguments and travels deep into the core principles of the human intellect of scientists and theologians to understand what they believe. It unravels the truth behind the reasoning of why different humans believe in what appears to be completely different things. The study uses elements of modern science and its cosmological worldview, such as singularity, spacetime, black holes, and quantum physics. It shows parallelism of modern scientific theories with various world Scriptures, such as Hindu and Islamic texts. This study does not argue the truth of any specific religion, but rather argues the existence of G-d from a broader perspective, using the exact same principles scientists use to formulate their worldview of the universe. This study shows the rationality and irrationality in the argumentative battle between science and religion. It attempts to end the debate and dispute between science and religion by understanding the truths behind them. It concludes that anyone who believes that the other is wrong is irrational, and that in reality science and religion complement one another. A theologian must also be a scientist, and a scientist must also be a theologian.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/5136323" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="1894776677e50c6dd66a8bd31058d2d6" rel="nofollow" data-download="{"attachment_id":32338775,"asset_id":5136323,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/32338775/download_file?st=MTc0MDg3MzQ2NSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="6922902" href="https://khalifa.academia.edu/AbdullaGaladari">Abdulla Galadari</a><script data-card-contents-for-user="6922902" type="text/json">{"id":6922902,"first_name":"Abdulla","last_name":"Galadari","domain_name":"khalifa","page_name":"AbdullaGaladari","display_name":"Abdulla Galadari","profile_url":"https://khalifa.academia.edu/AbdullaGaladari?f_ri=79394","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_5136323 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="5136323"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 5136323, container: ".js-paper-rank-work_5136323", });

This has affected the course of humanity and how society has prejudice towards either science or religion. Atheist scientists believe in what they know because they believe in reason and think that theists are unreasonable. The paper brings the problems facing humanity today between science, religion, and secularism within societies. The followers of each could be fanatics of their own group. The paper tries to reconcile the debate between atheists and theists, under the microscope of science. This study makes an analogy of G-d and gravity. It shows that the power of reason used by scientists to deduce gravity is the exact same reasoning that theists use to believe in G-d. The study goes beyond philosophical arguments and travels deep into the core principles of the human intellect of scientists and theologians to understand what they believe. It unravels the truth behind the reasoning of why different humans believe in what appears to be completely different things. The study uses elements of modern science and its cosmological worldview, such as singularity, spacetime, black holes, and quantum physics. It shows parallelism of modern scientific theories with various world Scriptures, such as Hindu and Islamic texts. This study does not argue the truth of any specific religion, but rather argues the existence of G-d from a broader perspective, using the exact same principles scientists use to formulate their worldview of the universe. This study shows the rationality and irrationality in the argumentative battle between science and religion. It attempts to end the debate and dispute between science and religion by understanding the truths behind them. It concludes that anyone who believes that the other is wrong is irrational, and that in reality science and religion complement one another. A theologian must also be a scientist, and a scientist must also be a theologian.","downloadable_attachments":[{"id":32338775,"asset_id":5136323,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":6922902,"first_name":"Abdulla","last_name":"Galadari","domain_name":"khalifa","page_name":"AbdullaGaladari","display_name":"Abdulla Galadari","profile_url":"https://khalifa.academia.edu/AbdullaGaladari?f_ri=79394","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":106,"name":"Religion","url":"https://www.academia.edu/Documents/in/Religion?f_ri=79394","nofollow":true},{"id":498,"name":"Physics","url":"https://www.academia.edu/Documents/in/Physics?f_ri=79394","nofollow":true},{"id":518,"name":"Quantum Physics","url":"https://www.academia.edu/Documents/in/Quantum_Physics?f_ri=79394","nofollow":true},{"id":821,"name":"Philosophy of Science","url":"https://www.academia.edu/Documents/in/Philosophy_of_Science?f_ri=79394","nofollow":true},{"id":902,"name":"Philosophy Of Religion","url":"https://www.academia.edu/Documents/in/Philosophy_Of_Religion?f_ri=79394"},{"id":1052,"name":"Atheism","url":"https://www.academia.edu/Documents/in/Atheism?f_ri=79394"},{"id":3815,"name":"Spirituality","url":"https://www.academia.edu/Documents/in/Spirituality?f_ri=79394"},{"id":4751,"name":"Black Holes","url":"https://www.academia.edu/Documents/in/Black_Holes?f_ri=79394"},{"id":23179,"name":"Astrophysics","url":"https://www.academia.edu/Documents/in/Astrophysics?f_ri=79394"},{"id":47598,"name":"Cosmology","url":"https://www.academia.edu/Documents/in/Cosmology?f_ri=79394"},{"id":51567,"name":"Universe","url":"https://www.academia.edu/Documents/in/Universe?f_ri=79394"},{"id":57413,"name":"Singularity","url":"https://www.academia.edu/Documents/in/Singularity?f_ri=79394"},{"id":79394,"name":"Gravity","url":"https://www.academia.edu/Documents/in/Gravity?f_ri=79394"},{"id":170678,"name":"Theism","url":"https://www.academia.edu/Documents/in/Theism?f_ri=79394"},{"id":187233,"name":"Worldview","url":"https://www.academia.edu/Documents/in/Worldview-3?f_ri=79394"},{"id":257714,"name":"Divinity","url":"https://www.academia.edu/Documents/in/Divinity?f_ri=79394"},{"id":500583,"name":"Secular","url":"https://www.academia.edu/Documents/in/Secular?f_ri=79394"},{"id":513701,"name":"Spacetime","url":"https://www.academia.edu/Documents/in/Spacetime?f_ri=79394"},{"id":602115,"name":"existence of God","url":"https://www.academia.edu/Documents/in/existence_of_God?f_ri=79394"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_74901404" data-work_id="74901404" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" rel="nofollow" href="https://www.academia.edu/74901404/A_vertical_race_up_and_back_down_with_and_without_drag">A vertical race up and back down with and without drag</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Two identical objects are simultaneously projected vertically upward with the same initial speed in a uniform gravitational field and then return to their starting point.

This study aims to develop an integrated geomatics approach for collecting and analyzing heterogeneous datasets within Geographic Information Systems (GIS) environment to predict potential risks of sea level variations over the Nile delta in 2025. Datasets include tide gauge (TG) records span 2008-2018, Global Navigations Satellite System (GNSS) observations to estimate land subsidence and consequently, absolute sea level rise, terrestrial high-accuracy Digital Elevation Model (DEM), and high-resolution satellite imageries were integrated to analyze and evaluate the impact of sea level rise on the coastal area of the Nile delta. Based on the available TG records over five sites, the statistical prediction has been carried out to forecast sea water variations in the next five years over the study area. Next, potentially inundated areas have been delineated for two cases: Mean Sea Level (MSL) and storm surges potential risks (High High water level (HHWL). The results indicate that the flooded area based on the MSL scenario represents only 5% of the total area of the entire study region, contrasting to earlier un-realistic estimates. Moreover, it has been found that the storm surge case produces potential risks 118% higher than those of MSL. Also, digital maps depicting all possible hazardous areas have been developed. Finally, it can be concluded that the presented integrated approach proves to be significantly effective in risk assessment over the Nile delta, helpful for decision makers to plan actions needed in coastal zone management, and it is reasonable to be applied in other similar regions worldwide.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/51074378" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="c03bfa6f5a84e1efbff21baaf0d5a030" rel="nofollow" data-download="{"attachment_id":68930050,"asset_id":51074378,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/68930050/download_file?st=MTc0MDg3MzQ2NSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="20000981" href="https://nwrc-egypt.academia.edu/EssamAl_krargy">Essam Al_krargy</a><script data-card-contents-for-user="20000981" type="text/json">{"id":20000981,"first_name":"Essam","last_name":"Al_krargy","domain_name":"nwrc-egypt","page_name":"EssamAl_krargy","display_name":"Essam Al_krargy","profile_url":"https://nwrc-egypt.academia.edu/EssamAl_krargy?f_ri=79394","photo":"https://0.academia-photos.com/20000981/5564636/6336561/s65_essam.al_krargy.jpg"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-51074378">+1</span><div class="hidden js-additional-users-51074378"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://nwrc-egypt.academia.edu/GomaaDawod">Gomaa Dawod</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-51074378'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-51074378').html();

This study aims to develop an integrated geomatics approach for collecting and analyzing heterogeneous datasets within Geographic Information Systems (GIS) environment to predict potential risks of sea level variations over the Nile delta in 2025. Datasets include tide gauge (TG) records span 2008-2018, Global Navigations Satellite System (GNSS) observations to estimate land subsidence and consequently, absolute sea level rise, terrestrial high-accuracy Digital Elevation Model (DEM), and high-resolution satellite imageries were integrated to analyze and evaluate the impact of sea level rise on the coastal area of the Nile delta. Based on the available TG records over five sites, the statistical prediction has been carried out to forecast sea water variations in the next five years over the study area. Next, potentially inundated areas have been delineated for two cases: Mean Sea Level (MSL) and storm surges potential risks (High High water level (HHWL). The results indicate that the flooded area based on the MSL scenario represents only 5% of the total area of the entire study region, contrasting to earlier un-realistic estimates. Moreover, it has been found that the storm surge case produces potential risks 118% higher than those of MSL. Also, digital maps depicting all possible hazardous areas have been developed. Finally, it can be concluded that the presented integrated approach proves to be significantly effective in risk assessment over the Nile delta, helpful for decision makers to plan actions needed in coastal zone management, and it is reasonable to be applied in other similar regions worldwide.","downloadable_attachments":[{"id":68930050,"asset_id":51074378,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":20000981,"first_name":"Essam","last_name":"Al_krargy","domain_name":"nwrc-egypt","page_name":"EssamAl_krargy","display_name":"Essam Al_krargy","profile_url":"https://nwrc-egypt.academia.edu/EssamAl_krargy?f_ri=79394","photo":"https://0.academia-photos.com/20000981/5564636/6336561/s65_essam.al_krargy.jpg"},{"id":630843,"first_name":"Gomaa","last_name":"Dawod","domain_name":"nwrc-egypt","page_name":"GomaaDawod","display_name":"Gomaa Dawod","profile_url":"https://nwrc-egypt.academia.edu/GomaaDawod?f_ri=79394","photo":"https://0.academia-photos.com/630843/217786/18385729/s65_gomaa.dawod.jpg"}],"research_interests":[{"id":404,"name":"Geodesy","url":"https://www.academia.edu/Documents/in/Geodesy?f_ri=79394","nofollow":true},{"id":4863,"name":"GPS Applications","url":"https://www.academia.edu/Documents/in/GPS_Applications?f_ri=79394","nofollow":true},{"id":25384,"name":"Global Positioning System","url":"https://www.academia.edu/Documents/in/Global_Positioning_System?f_ri=79394","nofollow":true},{"id":32574,"name":"Physical Geodesy","url":"https://www.academia.edu/Documents/in/Physical_Geodesy?f_ri=79394","nofollow":true},{"id":79394,"name":"Gravity","url":"https://www.academia.edu/Documents/in/Gravity?f_ri=79394"},{"id":369308,"name":"GNSS and GPS","url":"https://www.academia.edu/Documents/in/GNSS_and_GPS?f_ri=79394"},{"id":939612,"name":"Geodesy and Global Positioning System (GPS) and Their Applications In Earth Sciences","url":"https://www.academia.edu/Documents/in/Geodesy_and_Global_Positioning_System_GPS_and_Their_Applications_In_Earth_Sciences?f_ri=79394"},{"id":1009312,"name":"Geographic Information Systems (GIS)","url":"https://www.academia.edu/Documents/in/Geographic_Information_Systems_GIS_?f_ri=79394"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_40601487 coauthored" data-work_id="40601487" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/40601487/Steve_Paxton_Drafting_Interior_Techniques">Steve Paxton: Drafting Interior Techniques</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Steve Paxton: Drafting Interior Techniques is a collective reader/companion to Steve Paxton's life and work edited by Romain Bigé at the occasion of a retrospective exhibition that took place in Lisbon, Portugal.

This moment is the state of rest and we can observe motion only with the help our memory, that is, by experience. If motion were absolute, then we could be in the past, present, and future, we could travel in time. In reality, we compare what was before with what is now and thus comprehend the change, which we interpret as movement. If we did not have memory, we would not be able to comprehend change, we would always see the present image. Once again, it all depends on which angle we consider the given phenomenon. From the point of view of the present time, there is always a state of rest; from the point of view of experience – there is motion. The state of rest and motion occur simultaneously.

In this regard, a series of shaking table 1-g tests are performed for a 1 25 scaled-down caisson quay wall with two different seabed interface conditions. Here, the wall is tested in two cases: with and without (no-mitigation case) applying the deformable panels. Being installed behind the walls, the panels applied in the tests have different mechanical properties. In the model test, the harmonic base motions are used with constant frequency and amplitude. In all tests, the foundation soil beneath the caisson wall is assumed as dense and non liquefiable. However, in order to reproduce a loose backfill situation in the model, the backfill soil is constructed with relative density of 25%. Furthermore, to support the experimental results, a series of finite difference effective-stress analyses are performed in the prototype scale. The mitigation results show that the deformable panels can significantly decrease the seaward movement, settlement and inclination of wall as well as the total pressure recorded behind the caisson wall.
