All articles, in one way or another, have a connection with the Second Law of Thermodynamics. The content of the articles is given in a concise form. The articles were published in different journals at different times. Main topics are presented: gravity, biography of the Earth, physics of global warming-cooling cycles, multiverse. The articles are based on the laws of classical physics. Along the way, it should be noted that the Second Law of thermodynamics can be formulated as the Law of Matter Cooling. As it cools down, the processes of condensation, separation, and changes in the aggregate states of matter occur. In accordance with these changes, a picture of the world is being formed. Also, the main driving force of these processes is the inverse temperature dependence of the forces of gravity. As matter cools, the forces of gravity increase. The actions of these phenomena in the compartment form a picture of the world. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gravitational%20forces" title="gravitational forces">gravitational forces</a>, <a href="https://publications.waset.org/abstracts/search?q=cooling%20of%20matter" title=" cooling of matter"> cooling of matter</a>, <a href="https://publications.waset.org/abstracts/search?q=inverse%20temperature%20dependence%20of%20gravitational%20forces" title=" inverse temperature dependence of gravitational forces"> inverse temperature dependence of gravitational forces</a>, <a href="https://publications.waset.org/abstracts/search?q=planetary%20model%20of%20the%20atom" title=" planetary model of the atom"> planetary model of the atom</a> </p> <a href="https://publications.waset.org/abstracts/172167/picture-of-the-world-by-the-second-law-of-thermodynamic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172167.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">244</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9265</span> Physics of Black Holes.

All interaction schemes are built on the basis of Newton's laws of classical mechanics and Rutherford's planetary model of the structure of the atom. The basis of all constructions is the gyroscopic effect of rotation of all particles of the atomic structure. In this case, interatomic and intermolecular bonds are accepted as the static part of the gyroscope, and the rotation of an electron in an atom is accepted as the dynamic part. The structure of the planet Earth is accepted as a model of the structure of the Black Hole. Namely, gravitational and thermodynamic phenomena in the structure of the planet Earth are accepted as a model. Based on this model, assumptions are made about the processes inside the Black Hole. Moreover, a version is put forward, a scheme of a closed cycle of transformation of matter in the Universe. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=black%20hole" title="black hole">black hole</a>, <a href="https://publications.waset.org/abstracts/search?q=gravity" title=" gravity"> gravity</a>, <a href="https://publications.waset.org/abstracts/search?q=inverse%20temperature%20dependence%20of%20gravitational%20forces" title=" inverse temperature dependence of gravitational forces"> inverse temperature dependence of gravitational forces</a>, <a href="https://publications.waset.org/abstracts/search?q=second%20law%20of%20thermodynamics" title=" second law of thermodynamics"> second law of thermodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=gyroscopic%20effect" title=" gyroscopic effect"> gyroscopic effect</a>, <a href="https://publications.waset.org/abstracts/search?q=dark%20matter" title=" dark matter"> dark matter</a> </p> <a href="https://publications.waset.org/abstracts/192968/physics-of-black-holes-a-closed-cycle-of-transformation-of-matter-in-the-universe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192968.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">25</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9264</span> Numerical Study on the Hazards of Gravitational Forces on Cerebral Aneurysms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hashem%20M.%20Alargha">Hashem M.

A CFD simulation using fluid-solid interactions scheme has been conducted to investigate the gravitational effects and hazards inside cerebral aneurysms. Medical data have been used to derive the size and geometry of a simple aneurysm on a T-shaped bifurcation. The results show that gravitational force has no effect on maximum Wall Shear Stress (WSS); hence, it will not cause aneurysm initiation/formation.

Starfish oocytes provide an excellent model for interrogating the movement of cell components due to their unusually large size, ease of handling, and high transparency. Chromosomes from starfish oocytes can be visualised by microinjection of the histone-H2B-mCherry plasmid into the oocytes. The movement of the chromosomes can then be tracked by live-cell fluorescence microscopy. The results from experiments using these methods suggest that there is a replicable downward movement of centrally located chromosomes at a median velocity of 0.39 μm/min. Chromosomes nearer the nuclear boundary showed more restricted movement. Chromosome density and shape could also be altered by microinjection of restriction enzymes, primarily Alu1, before imaging. This was found to alter the speed of chromosome movement, with chromosomes from Alu1-injected nuclei showing a median downward velocity of 0.60 μm/min. Overall, these results suggest that there is a non-negligible movement of chromosomes in response to gravitational forces and that this movement can be altered by enzyme activity. Future directions based on these results could interrogate if this observed downward movement extends to other cell components and to other cell types. Additionally, it may be important to understand whether gravitational orientation and vertical positioning of cell components alter cell behaviour. The findings here may have implications for current cell culture practices, which do not replicate cell orientations or external forces experienced in vivo. It is possible that a failure to account for gravitational forces in 2D cell culture alters experimental results and the accuracy of conclusions drawn from them. Understanding possible behavioural changes in cells due to the effects of gravity would therefore be beneficial. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=starfish" title="starfish">starfish</a>, <a href="https://publications.waset.org/abstracts/search?q=oocytes" title=" oocytes"> oocytes</a>, <a href="https://publications.waset.org/abstracts/search?q=live-cell%20imaging" title=" live-cell imaging"> live-cell imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=microinjection" title=" microinjection"> microinjection</a>, <a href="https://publications.waset.org/abstracts/search?q=chromosome%20dynamics" title=" chromosome dynamics"> chromosome dynamics</a> </p> <a href="https://publications.waset.org/abstracts/158323/understanding-chromosome-movement-in-starfish-oocytes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158323.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">104</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9261</span> Prediction of the Thermal Parameters of a High-Temperature Metallurgical Reactor Using Inverse Heat Transfer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hafid">Mohamed Hafid</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcel%20Lacroix"> Marcel Lacroix</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents an inverse analysis for predicting the thermal conductivities and the heat flux of a high-temperature metallurgical reactor simultaneously.

In the first step, the location of the laser center is estimated using a coarse and uniform grid system. In the second step, the front-surface temperature is recovered in good accuracy using a multiple grid system in which fine mesh is used at laser spot center to capture the drastic temperature rise in this region but coarse mesh is employed in the peripheral region to reduce the total number of sensors required. The effectiveness of the two-step approach and the multiple grid system are demonstrated by the illustrative inverse solutions. If the measurement data for the temperature and heat flux on the back surface do not contain random error, the proposed multigrid approach can yield more accurate inverse solutions. When the back-surface measurement data contain random noise, accurate inverse solutions cannot be obtained if both temperature and heat flux are measured on the back surface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conduction" title="conduction">conduction</a>, <a href="https://publications.waset.org/abstracts/search?q=inverse%20problems" title=" inverse problems"> inverse problems</a>, <a href="https://publications.waset.org/abstracts/search?q=conjugated%20gradient%20method" title=" conjugated gradient method"> conjugated gradient method</a>, <a href="https://publications.waset.org/abstracts/search?q=laser" title=" laser"> laser</a> </p> <a href="https://publications.waset.org/abstracts/91353/a-multigrid-approach-for-three-dimensional-inverse-heat-conduction-problems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91353.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">369</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9259</span> An Inverse Heat Transfer Algorithm for Predicting the Thermal Properties of Tumors during Cryosurgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hafid">Mohamed Hafid</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcel%20Lacroix"> Marcel Lacroix</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed at developing an inverse heat transfer approach for predicting the time-varying freezing front and the temperature distribution of tumors during cryosurgery. Using a temperature probe pressed against the layer of tumor, the inverse approach is able to predict simultaneously the metabolic heat generation and the blood perfusion rate of the tumor. Once these parameters are predicted, the temperature-field and time-varying freezing fronts are determined with the direct model. The direct model rests on one-dimensional <em>Pennes</em> bioheat equation. The phase change problem is handled with the enthalpy method. The <em>Levenberg-Marquardt</em> Method (LMM) combined to the <em>Broyden</em> Method (BM) is used to solve the inverse model.

This research investigates how PoP package warpage patterns are affected by assembling process parameters, including substrate temperature, injection speed, injection temperature, and compound forces. We also investigate how warpage patterns are affected by the location of the silicon chip. The methodologies used in this research are design of experiment and warpage simulation via ANSYS. We propose a regression model to predict the warpage value as a function of substrate temperature, injection speed, injection temperature, and compound forces. Our results show that interaction effects exist between substrate temperature and compound forces and between injection speed and injection temperature. Therefore, determining the optimal values for substrate temperature, compound forces, injection speed, and injection temperature cannot be done individually. Also, our results show that the warpage patterns based on the location of silicon chips can be classified into 11 groups, with the largest warpage occurring at the left-most and right-most sides. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=package-on-package" title="package-on-package">package-on-package</a>, <a href="https://publications.waset.org/abstracts/search?q=warpage" title=" warpage"> warpage</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20of%20experiment" title=" design of experiment"> design of experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/70571/the-investigation-of-the-impact-of-process-and-location-parameters-in-warpage-study-of-semiconductor-packages" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70571.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">306</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9255</span> On the Efficiency of a Double-Cone Gravitational Motor and Generator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Barenten%20Suciu">Barenten Suciu</a>, <a href="https://publications.waset.org/abstracts/search?q=Akio%20Miyamura"> Akio Miyamura</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, following the study-case of an inclined plane gravitational machine, efficiency of a double-cone gravitational motor and generator is evaluated. Two types of efficiency ratios, called <em>translational efficiency</em> and <em>rotational efficiency</em>, are defined relative to the intended duty of the gravitational machine, which can be either the production of translational kinetic energy, or rotational kinetic energy. One proved that, for pure rolling movement of the double- cone, in the absence of rolling friction, the total mechanical energy is conserved. In such circumstances, as the motion of the double-cone progresses along rails, the translational efficiency decreases and the rotational efficiency increases, in such way that sum of the rotational and translational efficiencies remains unchanged and equal to 1.

For a matrix A of order n whose LU-decomposition is A = LU, the multiplication count is O (n3). This includes the evaluation of the LU-decompositions of the inverse, the lower triangular decomposition of A as well as a “reduced matrix inverse”. If an explicit value of the inverse is not needed the order reduces to O (n3/2) to compute to compute inv(U) and the reduced inverse. For a symmetric matrix only O (n3/3) operations are required to compute inv(L) and the reduced inverse. An example is presented to demonstrate the capability of using the reduced matrix inverse in treating ill-conditioned systems. Besides the simplicity of Broyden's update, the method provides a mean to exploit the possible sparsity in the matrix and to derive a suitable preconditioner. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Broyden%27s%20updates" title="Broyden's updates">Broyden's updates</a>, <a href="https://publications.waset.org/abstracts/search?q=matrix%20inverse" title=" matrix inverse"> matrix inverse</a>, <a href="https://publications.waset.org/abstracts/search?q=inverse%20factorization" title=" inverse factorization"> inverse factorization</a>, <a href="https://publications.waset.org/abstracts/search?q=solution%20of%20linear%20algebraic%20equations" title=" solution of linear algebraic equations"> solution of linear algebraic equations</a>, <a href="https://publications.waset.org/abstracts/search?q=ill-conditioned%20matrices" title=" ill-conditioned matrices"> ill-conditioned matrices</a>, <a href="https://publications.waset.org/abstracts/search?q=preconditioning" title=" preconditioning"> preconditioning</a> </p> <a href="https://publications.waset.org/abstracts/22126/on-direct-matrix-factored-inversion-via-broydens-updates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22126.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">479</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9253</span> Estimation of Natural Convection Heat Transfer from Plate-Fin Heat Sinks in a Closed Enclosure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Han-Taw%20Chen">Han-Taw Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Chung-Hou%20Lai"> Chung-Hou Lai</a>, <a href="https://publications.waset.org/abstracts/search?q=Tzu-Hsiang%20Lin"> Tzu-Hsiang Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ge-Jang%20He"> Ge-Jang He</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study applies the inverse method and three-dimensional CFD commercial software in conjunction with the experimental temperature data to investigate the heat transfer and fluid flow characteristics of the plate-fin heat sink in a closed rectangular enclosure for various values of fin height.

However, during preliminary design, the focus lies on understanding the interaction between exoskeleton and the human body in terms of forces and moments, namely body mechanics. For the study at hand, a multi-body simulation approach has been enhanced to evaluate actual forces and moments in a human dummy model with and without a digital mock-up of an active exoskeleton. Therefore, different motion data have been gathered and processed to perform a musculosceletal analysis. The motion data are ground reaction forces, electromyography data (EMG) and human motion data recorded with a marker-based motion capture system. Based on the experimental data, the response of the human dummy model has been calibrated. Subsequently, the scalable human dummy model, in conjunction with the motion data, is connected with the exoskeleton structure. The results of the human-machine interaction (HMI) simulation platform are in particular resulting contact forces and human joint forces to compare with admissible values with regard to the human physiology. Furthermore, it provides feedback for the sizing of the exoskeleton structure in terms of resulting interface forces (stress justification) and the effect of its compliance. A stepwise approach for the setup and validation of the modeling strategy is presented and the potential for a more time and cost-effective development of wearable support structures is outlined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assistive%20devices" title="assistive devices">assistive devices</a>, <a href="https://publications.waset.org/abstracts/search?q=ergonomic%20design" title=" ergonomic design"> ergonomic design</a>, <a href="https://publications.waset.org/abstracts/search?q=inverse%20dynamics" title=" inverse dynamics"> inverse dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=inverse%20kinematics" title=" inverse kinematics"> inverse kinematics</a>, <a href="https://publications.waset.org/abstracts/search?q=multibody%20simulation" title=" multibody simulation"> multibody simulation</a> </p> <a href="https://publications.waset.org/abstracts/151467/a-human-centered-design-of-an-exoskeleton-using-multibody-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151467.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">162</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9251</span> Study of Natural Convection Heat Transfer of Plate-Fin Heat Sink</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Han-Taw%20Chen">Han-Taw Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Tzu-Hsiang%20Lin"> Tzu-Hsiang Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Chung-Hou%20Lai"> Chung-Hou Lai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study applies the inverse method and three-dimensional CFD commercial software in conjunction with the experimental temperature data to investigate the heat transfer and fluid flow characteristics of the plate-fin heat sink in a rectangular closed enclosure.

Newton also defines his Universal law of Gravitational force exist in same outstanding book, but at the end of 20th century and beginning of 21st century, we have tried a lot to specify and unify four or five Fundamental forces or Interaction exist in universe, but we failed every time. Usually, Gravity creates problems in this unification every single time, but in my previous papers and presentations, I defined and derived Field and force equations for Gravitational like Interactions for each and every kind of central systems. This force is named as Variational Force by me, and this force is generated by variation in the scalar field density around the body. In this particular paper, at first, I am specifying which type of Interactions are Fundamental in Universal sense (or in all type of central systems or bodies predicted by my N-time Inflationary Model of Universe) and then unify them in Universal framework (defined and derived by me as Universal Mechanics in a separate paper) as well. This will also be valid in Universal dynamical sense which includes inflations and deflations of universe, central system relativity, Universal relativity, ϕ-ψ transformation and transformation of spin, physical perception principle, Generalized Fundamental Dynamical Law and many other important Generalized Principles of Generalized Quantum Mechanics (GQM) and Central System Theory (CST). So, In this article, at first, I am Generalizing some Fundamental Principles, and then Unifying Variational Forces (General form of Gravitation like Interactions) and Flow Generated Force (General form of EM like Interactions), and then Unify all Fundamental Forces by specifying Weak and Strong Interactions in form of more basic terms - Variational, Flow Generated and Transformational Interactions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Central%20System%20Force" title="Central System Force">Central System Force</a>, <a href="https://publications.waset.org/abstracts/search?q=Disturbance%20Force" title=" Disturbance Force"> Disturbance Force</a>, <a href="https://publications.waset.org/abstracts/search?q=Flow%20Generated%20Forces" title=" Flow Generated Forces"> Flow Generated Forces</a>, <a href="https://publications.waset.org/abstracts/search?q=Generalized%20Nuclear%20Force" title=" Generalized Nuclear Force"> Generalized Nuclear Force</a>, <a href="https://publications.waset.org/abstracts/search?q=Generalized%20Weak%20Interactions" title=" Generalized Weak Interactions"> Generalized Weak Interactions</a>, <a href="https://publications.waset.org/abstracts/search?q=Generalized%20EM-Like%20Interactions" title=" Generalized EM-Like Interactions"> Generalized EM-Like Interactions</a>, <a href="https://publications.waset.org/abstracts/search?q=Imbalance%20Force" title=" Imbalance Force"> Imbalance Force</a>, <a href="https://publications.waset.org/abstracts/search?q=Spin%20Generated%20Forces" title=" Spin Generated Forces"> Spin Generated Forces</a>, <a href="https://publications.waset.org/abstracts/search?q=Transformation%20Generated%20Force" title=" Transformation Generated Force"> Transformation Generated Force</a>, <a href="https://publications.waset.org/abstracts/search?q=Unified%20Force" title=" Unified Force"> Unified Force</a>, <a href="https://publications.waset.org/abstracts/search?q=Universal%20Mechanics" title=" Universal Mechanics"> Universal Mechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=Uniform%20And%20Non-Uniform%20Variational%20Interactions" title=" Uniform And Non-Uniform Variational Interactions"> Uniform And Non-Uniform Variational Interactions</a>, <a href="https://publications.waset.org/abstracts/search?q=Variational%20Interactions" title=" Variational Interactions"> Variational Interactions</a> </p> <a href="https://publications.waset.org/abstracts/169765/specification-and-unification-of-all-fundamental-forces-exist-in-universe-in-the-theoretical-perspective-the-universal-mechanics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169765.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">50</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9248</span> A Stokes Optimal Control Model of Determining Cellular Interaction Forces during Gastrulation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuanhao%20Gao">Yuanhao Gao</a>, <a href="https://publications.waset.org/abstracts/search?q=Ping%20%20Lin"> Ping Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Kees%20Weijer"> Kees Weijer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An optimal control system model is proposed for the cell flow in the process of chick embryo gastrulation in this paper.

We carry out the model analysis using DC-measurements taken on both Si and advanced SiGe bipolar transistors. For the advanced industrial SiGe-HBTs, we consider both high-speed and high-power devices (both NPN and PNP transistors). The limitations of the local avalanche model in modeling the temperature dependence of the avalanche current mostly in the weak avalanche region are demonstrated.

With the first detection of gravitational waves from a pair of colliding black holes in September 2015 and subsequent detections including that of gravitational waves from a pair of colliding neutron stars, the ground-based interferometric gravitational wave observatories LIGO and VIRGO have opened the era of gravitational-wave and multi-messenger astronomy. Improving the sensitivity of the detectors is of paramount importance to increase the number and quality of the detections, fully exploiting this new information channel about the universe. Although still in the commissioning phase and not at nominal sensitivity, these interferometers are designed to be ultimately limited by a combination of shot noise and quantum radiation pressure noise, which define an envelope known as the standard quantum limit. Despite the name, this limit can be beaten with the use of advanced quantum measurement techniques, with the use of squeezed vacuum states being currently the most mature and promising. Different strategies for implementation of the technology in the large-scale detectors, in both their frequency-independent and frequency-dependent variations, are presented, together with an analysis of the main technological issues and expected sensitivity gain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gravitational%20waves" title="gravitational waves">gravitational waves</a>, <a href="https://publications.waset.org/abstracts/search?q=interferometers" title=" interferometers"> interferometers</a>, <a href="https://publications.waset.org/abstracts/search?q=squeezed%20vacuum" title=" squeezed vacuum"> squeezed vacuum</a>, <a href="https://publications.waset.org/abstracts/search?q=standard%20quantum%20limit" title=" standard quantum limit"> standard quantum limit</a> </p> <a href="https://publications.waset.org/abstracts/85856/using-squeezed-vacuum-states-to-enhance-the-sensitivity-of-ground-based-gravitational-wave-interferometers-beyond-the-standard-quantum-limit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85856.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9244</span> Congruences Induced by Certain Relations on Ag**-Groupoids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faisal%20Yousafzai">Faisal Yousafzai</a>, <a href="https://publications.waset.org/abstracts/search?q=Murad-ul-Islam%20Khan"> Murad-ul-Islam Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Kar%20Ping%20Shum"> Kar Ping Shum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We introduce the concept of partially inverse AG**-groupoids which is almost parallel to the concepts of E-inversive semigroups and E-inversive E-semigroups.

To modify the C/C composites, Silica (SiO<sub>2</sub>) powders were added into phenolic resin for carbon precursor. The preform plate of the precursor of C/C composites was prepared by conventional filament winding method. The C/C composites plates were obtained by carbonizing preform plate at 2200 °C under an argon atmosphere. At that time, the silicon carbides (SiC) were synthesized around the surfaces and the internal vacancies of the C/C composites. The frictional coefficient on the counter surfaces and specific wear volumes of the C/C composites were measured by our developed frictional test machine like pin-on disk type. The XRD indicated that SiC was synthesized in the body of C/C composite fabricated by current method. The results of friction test showed that coefficient of friction of unmodified C/C composites have temperature dependence when the test condition was changed. In contrast, frictional coefficient of the C/C composite modified with SiO<sub>2 </sub>powders was almost constant at about 0.27 when the temperature condition was changed from Room Temperature (RT) to 300 °C. The specific wear rate decreased from 25×10<sup>-6</sup> mm<sup>2</sup>/N to 0.1×10<sup>-6</sup> mm<sup>2</sup>/N. The observations of the surfaces after friction tests showed that the frictional surface of the modified C/C composites was covered with a film produced by the friction. This study found that synthesizing SiC around surface and internal vacancies of C/C composites was effective to moderate the dependence on the frictional coefficient and reduce to the abrasion of C/C composites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=C%2FC%20composites" title="C/C composites">C/C composites</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20coefficient" title=" friction coefficient"> friction coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a>, <a href="https://publications.waset.org/abstracts/search?q=SiC" title=" SiC"> SiC</a> </p> <a href="https://publications.waset.org/abstracts/64753/moderation-in-temperature-dependence-on-counter-frictional-coefficient-and-prevention-of-wear-of-cc-composites-by-synthesizing-sic-around-surface-and-internal-vacancies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64753.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">344</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9241</span> Inverse Matrix in the Theory of Dynamical Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Renata%20Masarova">Renata Masarova</a>, <a href="https://publications.waset.org/abstracts/search?q=Bohuslava%20Juhasova"> Bohuslava Juhasova</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Juhas"> Martin Juhas</a>, <a href="https://publications.waset.org/abstracts/search?q=Zuzana%20Sutova"> Zuzana Sutova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In dynamic system theory a mathematical model is often used to describe their properties.

Recommendations are also made at the of the study so as to skill acquisition through science and technology for self dependence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acquisition" title="acquisition">acquisition</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=self-dependence" title=" self-dependence"> self-dependence</a>, <a href="https://publications.waset.org/abstracts/search?q=science" title=" science"> science</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a> </p> <a href="https://publications.waset.org/abstracts/30436/the-importance-of-science-and-technology-education-in-skill-acquisition-for-self-dependence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30436.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">505</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9238</span> Enhancing Transfer Path Analysis with In-Situ Component Transfer Path Analysis for Interface Forces Identification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raef%20Cherif">Raef Cherif</a>, <a href="https://publications.waset.org/abstracts/search?q=Houssine%20Bakkali"> Houssine Bakkali</a>, <a href="https://publications.waset.org/abstracts/search?q=Wafaa%20El%20Khatiri"> Wafaa El Khatiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Yacine%20Yaddaden"> Yacine Yaddaden</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The analysis of how vibrations are transmitted between components is required in many engineering applications. Transfer path analysis (TPA) has been a valuable engineering tool for solving Noise, Vibration, and Harshness (NVH problems using sub-structuring applications. The most challenging part of a TPA analysis is estimating the equivalent forces at the contact points between the active and the passive side. Component TPA in situ Method calculates these forces by inverting the frequency response functions (FRFs) measured at the passive subsystem, relating the motion at indicator points to forces at the interface. However, matrix inversion could pose problems due to the ill-conditioning of the matrices leading to inaccurate results. This paper establishes a TPA model for an academic system consisting of two plates linked by four springs. A numerical study has been performed to improve the interface forces identification. Several parameters are studied and discussed, such as the singular value rejection and the number and position of indicator points chosen and used in the inversion matrix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transfer%20path%20analysis" title="transfer path analysis">transfer path analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=matrix%20inverse%20method" title=" matrix inverse method"> matrix inverse method</a>, <a href="https://publications.waset.org/abstracts/search?q=indicator%20points" title=" indicator points"> indicator points</a>, <a href="https://publications.waset.org/abstracts/search?q=SVD%20decomposition" title=" SVD decomposition"> SVD decomposition</a> </p> <a href="https://publications.waset.org/abstracts/166401/enhancing-transfer-path-analysis-with-in-situ-component-transfer-path-analysis-for-interface-forces-identification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166401.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">84</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9237</span> Base Change for Fisher Metrics: Case of the q-Gaussian Inverse Distribution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gabriel%20I.%20Loaiza%20Ossa">Gabriel I.

In the present paper, firstly, we arrive at this result by following a different path, much simpler than the previous ones. We first put the family in exponential form, thus endowing the family with a new set of parameters, or coordinates, θ₁, θ₂; then we determine the matrix of the Fisher metric in terms of these parameters; and finally we compute this matrix in the original parameters. Secondly, we define the inverse q-Gaussian distribution family (q < 3) as the family obtained by replacing the usual exponential function with the Tsallis q-exponential function in the expression for the inverse Gaussian distribution and observe that it supports two possible geometries, the Fisher and the q-Fisher geometry. And finally, we apply our strategy to obtain results about the Fisher and q-Fisher geometry of the inverse q-Gaussian distribution family, similar to the ones obtained in the case of the inverse Gaussian distribution family. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=base%20of%20changes" title="base of changes">base of
