Clearly, expressions for Lagrangians of the elementary modes of the system are given, which ends with the familiar classical equations of motion for the dissipative oscillator. The equation for one variable is the time reversed of the motion of the second variable. it discuss in detail the extended Bateman Lagrangian specifically for a dual extended damped oscillator time-dependent. A Hamilton-Jacobi analysis showing the equivalence with the Lagrangian approach is also obtained. For that purpose, the techniques of separation of variables were applied, and the quantization process was achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=doubling%20of%20degrees%20of%20freedom" title="doubling of degrees of freedom">doubling of degrees of freedom</a>, <a href="https://publications.waset.org/abstracts/search?q=dissipated%20harmonic%20oscillator" title=" dissipated harmonic oscillator"> dissipated harmonic oscillator</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamilton-Jacobi" title=" Hamilton-Jacobi"> Hamilton-Jacobi</a>, <a href="https://publications.waset.org/abstracts/search?q=time-dependent%20lagrangians" title=" time-dependent lagrangians"> time-dependent lagrangians</a>, <a href="https://publications.waset.org/abstracts/search?q=quantization" title=" quantization"> quantization</a> </p> <a href="https://publications.waset.org/abstracts/171405/quantization-of-damped-systems-based-on-the-doubling-of-degrees-of-freedom" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171405.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">68</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">1422</span> A Deep Explanation for the Formation of Force as a Foundational Law of Physics by Incorporating Unknown Degrees of Freedom into Space</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Farshad">Mohsen Farshad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Information and force definition has been intertwined with the concept of entropy for many years. The displacement information of degrees of freedom with Brownian motions at a given temperature in space emerges as an entropic force between species. Here, we use this concept of entropy to understand the underlying physics behind the formation of attractive and repulsive forces by imagining that space is filled with free Brownian degrees of freedom. We incorporate the radius of bodies and the distance between them into entropic force relation systematically. Using this modified gravitational entropic force, we derive the attractive entropic force between bodies without considering their spin. We further hypothesize a possible mechanism for the formation of the repulsive force between two bodies. We visually elaborate that the repulsive entropic force will be manifested through the rotation of degrees of freedom around the spinning particles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entropy" title="entropy">entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=information" title=" information"> information</a>, <a href="https://publications.waset.org/abstracts/search?q=force" title=" force"> force</a>, <a href="https://publications.waset.org/abstracts/search?q=Brownian%20Motions" title=" Brownian Motions"> Brownian Motions</a> </p> <a href="https://publications.waset.org/abstracts/150175/a-deep-explanation-for-the-formation-of-force-as-a-foundational-law-of-physics-by-incorporating-unknown-degrees-of-freedom-into-space" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150175.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">76</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">1421</span> Bioarm, a Prothesis without Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Sagouis">J.

The most expensive solutions surgically connect the prosthesis to nerve endings. There are also several types of non-invasive technologies that recover nerve messages passing through the muscles. After analyzing these messages, myoelectric prostheses perform the desired movement. The main goal is to avoid all surgeries, which can be heavy and offer cheaper alternatives. For an amputee, we use valid muscles to recover the electrical signal involved in a muscle movement. EMG sensors placed on the muscle allows us to measure a potential difference, which our program transforms into control for a robotic arm with two degrees of freedom. We have shown the feasibility of non-invasive prostheses with two degrees of freedom. Signal analysis and an increase in degrees of freedom is still being improved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prosthesis" title="prosthesis">prosthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=electromyography%20%28EMG%29" title=" electromyography (EMG)"> electromyography (EMG)</a>, <a href="https://publications.waset.org/abstracts/search?q=robotic%20arm" title=" robotic arm"> robotic arm</a>, <a href="https://publications.waset.org/abstracts/search?q=nerve%20message" title=" nerve message"> nerve message</a> </p> <a href="https://publications.waset.org/abstracts/15441/bioarm-a-prothesis-without-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15441.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">249</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">1420</span> Behavior Analysis Based on Nine Degrees of Freedom Sensor for Emergency Rescue Evacuation Support System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maeng-Hwan%20Hyun">Maeng-Hwan Hyun</a>, <a href="https://publications.waset.org/abstracts/search?q=Dae-Man%20Do"> Dae-Man Do</a>, <a href="https://publications.waset.org/abstracts/search?q=Young-Bok%20Choi"> Young-Bok Choi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Around the world, there are frequent incidents of natural disasters, such as earthquakes, tsunamis, floods, and snowstorms, as well as man made disasters such as fires, arsons, and acts of terror. These diverse and unpredictable adversities have resulted in a number of fatalities and injuries. If disaster occurrence can be assessed quickly and information such as the exact location of the disaster and evacuation routes can be provided, victims can promptly move to safe locations, minimizing losses. This paper proposes a behavior analysis method based on a nine degrees-of-freedom (9-DOF) sensor that is effective for the emergency rescue evacuation support system (ERESS), which is being researched with an objective of providing evacuation support during disasters. Based on experiments performed using the acceleration sensor and the gyroscope sensor in the 9-DOF sensor, data are analyzed for human behavior regarding stationary position, walking, running, and during emergency situation to suggest guidelines for system judgment. Using the results of the experiments performed to determine disaster occurrence, it was confirmed that the proposed method quickly determines whether a disaster has occurred. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=behavior%20analysis" title="behavior analysis">behavior analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=nine%20degrees%20of%20freedom%20sensor" title=" nine degrees of freedom sensor"> nine degrees of freedom sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency%20rescue" title=" emergency rescue"> emergency rescue</a>, <a href="https://publications.waset.org/abstracts/search?q=disaster" title=" disaster"> disaster</a> </p> <a href="https://publications.waset.org/abstracts/4031/behavior-analysis-based-on-nine-degrees-of-freedom-sensor-for-emergency-rescue-evacuation-support-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4031.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">304</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">1419</span> Human Trafficking: Stand for Freedom</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Madhumitha%20Rajasekaran">Madhumitha Rajasekaran </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Freedom is a short, powerful word we take for granted every day.

In the modeling of complex structures by finite elements, various elements can be used: beam element, membrane element, solid element, plates and shells elements. These elements formulated according to the classical formulation and do not generally share the same nodal degrees of freedom, which complicates the development of a compatible model. The compatibility of the elements with each other is often a difficult problem for modeling complicated structure. This compatibility is necessary to ensure the convergence. To overcome this problem, we have proposed finite elements with a rotational degree of freedom. The study used is based on the strain approach formulation with 2D and 3D formulation with different degrees of freedom at each node. For the comparison and confrontation of results; the finite elements available in ABAQUS/Standard are used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compatibility%20requirement" title="compatibility requirement">compatibility requirement</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20structures" title=" complex structures"> complex structures</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20elements" title=" finite elements"> finite elements</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20approach" title=" strain approach"> strain approach</a> </p> <a href="https://publications.waset.org/abstracts/34144/modeling-of-complex-structures-shear-wall-with-openings-and-stiffened-shells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34144.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">443</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">1417</span> An Efficient Discrete Chaos in Generalized Logistic Maps with Applications in Image Encryption </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashish%20Ashish">Ashish Ashish</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the last few decades, the discrete chaos of difference equations has gained a massive attention of academicians and scholars due to its tremendous applications in each and every branch of science, such as cryptography, traffic control models, secure communications, weather forecasting, and engineering. In this article, a generalized logistic discrete map is established and discrete chaos is reported through period doubling bifurcation, period three orbit and Lyapunov exponent. It is interesting to see that the generalized logistic map exhibits superior chaos due to the presence of an extra degree of freedom of an ordered parameter. The period doubling bifurcation and Lyapunov exponent are demonstrated for some particular values of parameter and the discrete chaos is determined in the sense of Devaney's definition of chaos theoretically as well as numerically. Moreover, the study discusses an extended chaos based image encryption and decryption scheme in cryptography using this novel system. Surprisingly, a larger key space for coding and more sensitive dependence on initial conditions are examined for encryption and decryption of text messages, images and videos which secure the system strongly from external cyber attacks, coding attacks, statistic attacks and differential attacks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chaos" title="chaos">chaos</a>, <a href="https://publications.waset.org/abstracts/search?q=period-doubling" title=" period-doubling"> period-doubling</a>, <a href="https://publications.waset.org/abstracts/search?q=logistic%20map" title=" logistic map"> logistic map</a>, <a href="https://publications.waset.org/abstracts/search?q=Lyapunov%20exponent" title=" Lyapunov exponent"> Lyapunov exponent</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20encryption" title=" image encryption"> image encryption</a> </p> <a href="https://publications.waset.org/abstracts/112408/an-efficient-discrete-chaos-in-generalized-logistic-maps-with-applications-in-image-encryption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112408.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">1416</span> Gaussian Operations with a Single Trapped Ion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bruna%20G.%20M.%20Ara%C3%BAjo">Bruna G.

As we work with quantum information and computation with continuous variables, Gaussian states are needed to better describe these systems. Analyzing a single ion locked in a Paul trap we use the interaction picture to obtain a toolbox of Gaussian operations with the ion-laser interaction Hamiltionian. This is achieved exciting the ion through the combination of two lasers of distinct frequencies corresponding to different sidebands of the external degrees of freedom. First we study the case of a trap with 1 mode and then the case with 2 modes. In this way, we achieve different continuous variables gates just by changing the external degrees of freedom of the trap and combining the Hamiltonians of blue and red sidebands. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paul%20trap" title="Paul trap">Paul trap</a>, <a href="https://publications.waset.org/abstracts/search?q=ion-laser%20interaction" title=" ion-laser interaction"> ion-laser interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaussian%20operations" title=" Gaussian operations"> Gaussian operations</a> </p> <a href="https://publications.waset.org/abstracts/18445/gaussian-operations-with-a-single-trapped-ion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18445.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">685</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">1415</span> Design and Optimization of a 6 Degrees of Freedom Co-Manipulated Parallel Robot for Prostate Brachytherapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aziza%20Ben%20Halima">Aziza Ben Halima</a>, <a href="https://publications.waset.org/abstracts/search?q=Julien%20Bert"> Julien Bert</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitris%20Visvikis"> Dimitris Visvikis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we propose designing and evaluating a parallel co-manipulated robot dedicated to low-dose-rate prostate brachytherapy. We developed 6 degrees of freedom compact and lightweight robot easy to install in the operating room thanks to its parallel design. This robotic system provides a co-manipulation allowing the surgeon to keep control of the needle’s insertion and consequently to improve the acceptability of the plan for the clinic. The best dimension’s configuration was solved by calculating the geometric model and using an optimization approach. The aim was to ensure the whole coverage of the prostate volume and consider the allowed free space around the patient that includes the ultrasound probe. The final robot dimensions fit in a cube of 300 300 300 mm³. A prototype was 3D printed, and the robot workspace was measured experimentally. The results show that the proposed robotic system satisfies the medical application requirements and permits the needle to reach any point within the prostate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=medical%20robotics" title="medical robotics">medical robotics</a>, <a href="https://publications.waset.org/abstracts/search?q=co-manipulation" title=" co-manipulation"> co-manipulation</a>, <a href="https://publications.waset.org/abstracts/search?q=prostate%20brachytherapy" title=" prostate brachytherapy"> prostate brachytherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/131084/design-and-optimization-of-a-6-degrees-of-freedom-co-manipulated-parallel-robot-for-prostate-brachytherapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131084.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">205</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">1414</span> From Protector to Violator: Assessing State&#039;s Role in Protecting Freedom of Religion in Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manotar%20Tampubolon">Manotar Tampubolon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indonesia is a country that upholds the law, human rights and religious freedom.

State action that interferes freedom of religion is done in various ways both intentionally or negligently or not to perform its obligations in the enforcement of human rights (human rights due diligence). Besides the state, non-state actors such as religious organizations, individuals also become violators of the rights of religious freedom. This article will discuss two fundamental issues that interfere freedom of religion in Indonesia after democratic era. In addition, this article also discusses a comprehensive state policy that discriminates minority religions to manifest their faith. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=religious%20freedom" title="religious freedom">religious freedom</a>, <a href="https://publications.waset.org/abstracts/search?q=constitution" title=" constitution"> constitution</a>, <a href="https://publications.waset.org/abstracts/search?q=minority%20faith" title=" minority faith"> minority faith</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20actor" title=" state actor"> state actor</a> </p> <a href="https://publications.waset.org/abstracts/64690/from-protector-to-violator-assessing-states-role-in-protecting-freedom-of-religion-in-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64690.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">403</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">1413</span> Freedom and the Value of Games: How to Overcome the Challenges in the Gamification of Necessary Learning Tasks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonathan%20May">Jonathan May</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper argues that the value of games relates to the sensation of freedom they create, and this in turn results from their nature as voluntary, non-necessary tasks. Attempts to gamify necessary learning tasks are therefore challenged to create this sensation of freedom and so they often fail to create the pleasure and value found in traditional games. It then demonstrates a route to creating this sensation of freedom through the maximization of varied and creative solutions to such problems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gamification" title="gamification">gamification</a>, <a href="https://publications.waset.org/abstracts/search?q=games" title=" games"> games</a>, <a href="https://publications.waset.org/abstracts/search?q=philosophy%20of%20games" title=" philosophy of games"> philosophy of games</a>, <a href="https://publications.waset.org/abstracts/search?q=freedom" title=" freedom"> freedom</a>, <a href="https://publications.waset.org/abstracts/search?q=voluntary%20action" title=" voluntary action"> voluntary action</a>, <a href="https://publications.waset.org/abstracts/search?q=necessity" title=" necessity"> necessity</a>, <a href="https://publications.waset.org/abstracts/search?q=motivation" title=" motivation"> motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20of%20games" title=" value of games"> value of games</a> </p> <a href="https://publications.waset.org/abstracts/151112/freedom-and-the-value-of-games-how-to-overcome-the-challenges-in-the-gamification-of-necessary-learning-tasks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151112.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">176</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">1412</span> Comparison between the Quadratic and the Cubic Linked Interpolation on the Mindlin Plate Four-Node Quadrilateral Finite Elements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dragan%20Ribari%C4%87">Dragan Ribarić</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We employ the so-called problem-dependent linked interpolation concept to develop two cubic 4-node quadrilateral Mindlin plate finite elements with 12 external degrees of freedom. In the problem-independent linked interpolation, the interpolation functions are independent of any problem material parameters and the rotation fields are not expressed in terms of the nodal displacement parameters. On the contrary, in the problem-dependent linked interpolation, the interpolation functions depend on the material parameters and the rotation fields are expressed in terms of the nodal displacement parameters. Two cubic 4-node quadrilateral plate elements are presented, named Q4-U3 and Q4-U3R5. The first one is modelled with one displacement and two rotation degrees of freedom in every of the four element nodes and the second element has five additional internal degrees of freedom to get polynomial completeness of the cubic form and which can be statically condensed within the element. Both elements are able to pass the constant-bending patch test exactly as well as the non-zero constant-shear patch test on the oriented regular mesh geometry in the case of cylindrical bending. In any mesh shape, the elements have the correct rank and only the three eigenvalues, corresponding to the solid body motions are zero. There are no additional spurious zero modes responsible for instability of the finite element models. In comparison with the problem-independent cubic linked interpolation implemented in Q9-U3, the nine-node plate element, significantly less degrees of freedom are employed in the model while retaining the interpolation conformity between adjacent elements. The presented elements are also compared to the existing problem-independent quadratic linked-interpolation element Q4-U2 and to the other known elements that also use the quadratic or the cubic linked interpolation, by testing them on several benchmark examples. Simple functional upgrading from the quadratic to the cubic linked interpolation, implemented in Q4-U3 element, showed no significant improvement compared to the quadratic linked form of the Q4-U2 element. Only when the additional bubble terms are incorporated in the displacement and rotation function fields, which complete the full cubic linked interpolation form, qualitative improvement is fulfilled in the Q4-U3R5 element. Nevertheless, the locking problem exists even for the both presented elements, like in all pure displacement elements when applied to very thin plates modelled by coarse meshes. But good and even slightly better performance can be noticed for the Q4-U3R5 element when compared with elements from the literature, if the model meshes are moderately dense and the plate thickness not extremely thin. In some cases, it is comparable to or even better than Q9-U3 element which has as many as 12 more external degrees of freedom. A significant improvement can be noticed in particular when modeling very skew plates and models with singularities in the stress fields as well as circular plates with distorted meshes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mindlin%20plate%20theory" title="Mindlin plate theory">Mindlin plate theory</a>, <a href="https://publications.waset.org/abstracts/search?q=problem-independent%20linked%20interpolation" title=" problem-independent linked interpolation"> problem-independent linked interpolation</a>, <a href="https://publications.waset.org/abstracts/search?q=problem-dependent%20interpolation" title=" problem-dependent interpolation"> problem-dependent interpolation</a>, <a href="https://publications.waset.org/abstracts/search?q=quadrilateral%20displacement-based%20plate%20finite%20elements" title=" quadrilateral displacement-based plate finite elements"> quadrilateral displacement-based plate finite elements</a> </p> <a href="https://publications.waset.org/abstracts/47597/comparison-between-the-quadratic-and-the-cubic-linked-interpolation-on-the-mindlin-plate-four-node-quadrilateral-finite-elements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47597.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">312</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">1411</span> Design of a 4-DOF Robot Manipulator with Optimized Algorithm for Inverse Kinematics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20G%C3%B3mez">S.

Defamation, censorship, fake news, misleading information, hate speech, breach of copyright etc., are only some of the violations, all of which can be derived from the harmful exercise of freedom of expression, all which become more salient in the internet. Here raises the question: how can we eliminate these problems, and practice our fundamental freedom rightfully? To answer this question, we should understand the elements and the characteristic of the nature of freedom of expression, and the role of the actors whose duties and responsibilities are crucial in the prevalence of this fundamental freedom. To achieve this goal, this paper will explore the European practice to understand instructions found in the case-law of the European Court of Human rights for the rightful exercise of freedom of expression. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collision%20of%20rights" title="collision of rights">collision of rights</a>, <a href="https://publications.waset.org/abstracts/search?q=European%20case-law" title=" European case-law"> European case-law</a>, <a href="https://publications.waset.org/abstracts/search?q=freedom%20opinion%20and%20expression" title=" freedom opinion and expression"> freedom opinion and expression</a>, <a href="https://publications.waset.org/abstracts/search?q=media%20law" title=" media law"> media law</a>, <a href="https://publications.waset.org/abstracts/search?q=freedom%20of%20information" title=" freedom of information"> freedom of information</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20expression" title=" online expression"> online expression</a> </p> <a href="https://publications.waset.org/abstracts/104514/freedom-with-limitations-the-nature-of-free-expression-in-the-european-case-law" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104514.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">139</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">1409</span> Design and Fabrication of a Smart Quadruped Robot</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shivani%20Verma">Shivani Verma</a>, <a href="https://publications.waset.org/abstracts/search?q=Amit%20Agrawal"> Amit Agrawal</a>, <a href="https://publications.waset.org/abstracts/search?q=Pankaj%20Kumar%20Meena"> Pankaj Kumar Meena</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashish%20B.%20Deoghare"> Ashish B.

The need for robots to replace human work in different dangerous fields such as underground mining, nuclear power station and war against terrorist attack has gained huge attention. Most of the robot design is based on human structure popularly known as humanoid robots. However, the problems encountered in humanoid robots includes low speed of movement, misbalancing in structure, poor load carrying capacity, etc. The simplification and adaptation of the fundamental design principles seen in animals have led to the creation of bio-inspired robots. But the major challenges observed in naturally inspired robot include complexity in structure, several degrees of freedom and energy storage problem. The present work focuses on design and fabrication of a bionic quadruped walking robot which is based on different joint of quadruped mammals like a dog, cheetah, etc. The design focuses on the structure of the robot body which consists of four legs having three degrees of freedom per leg and the electronics system involved in it. The robot is built using readily available plastics and metals. The proposed robot is simple in construction and is able to move through uneven terrain, detect and locate obstacles and take images while carrying additional loads which may include hardware and sensors. The robot will find possible application in the artificial intelligence sector. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title="artificial intelligence">artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=bionic" title=" bionic"> bionic</a>, <a href="https://publications.waset.org/abstracts/search?q=quadruped%20robot" title=" quadruped robot"> quadruped robot</a>, <a href="https://publications.waset.org/abstracts/search?q=degree%20of%20freedom" title=" degree of freedom"> degree of freedom</a> </p> <a href="https://publications.waset.org/abstracts/79216/design-and-fabrication-of-a-smart-quadruped-robot" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79216.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">215</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">1408</span> Efficiency of the Strain Based Approach Formulation for Plate Bending Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Djamal%20Hamadi">Djamal Hamadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sifeddine%20Abderrahmani"> Sifeddine Abderrahmani</a>, <a href="https://publications.waset.org/abstracts/search?q=Toufik%20Maalem"> Toufik Maalem</a>, <a href="https://publications.waset.org/abstracts/search?q=Oussama%20Temami"> Oussama Temami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years many finite elements have been developed for plate bending analysis. The formulated elements are based on the strain based approach. This approach leads to the representation of the displacements by higher order polynomial terms without the need for the introduction of additional internal and unnecessary degrees of freedom. Good convergence can also be obtained when the results are compared with those obtained from the corresponding displacement based elements, having the same total number of degrees of freedom. Furthermore, the plate bending elements are free from any shear locking since they converge to the Kirchhoff solution for thin plates contrarily for the corresponding displacement based elements. In this paper the efficiency of the strain based approach compared to well known displacement formulation is presented. The results obtained by a new formulated plate bending element based on the strain approach and Kirchhoff theory are compared with some others elements.

The importance of academic freedom as a bedrock foundation that supports the work of the professoriate cannot be overstated, and there have been innumerable challenges that have attempted to curtail it. These challenges come from a variety of sources that span legal, ethical, cultural, institutional, and professional perspective and are amplified by social media, traditional media, and political action efforts. Because of these challenges, the development of a comprehensive institutional policy on academic freedom that addresses the principles, practices, and appropriate responses to modern challenges can be a daunting task.

In this prolific field, most of the literature is dedicated to the exploration of the two 'degrees of freedom' and how they impact the model’s properties (e.g., the average final opinion, the number of final clusters, etc.). These degrees of freedom are (1) the interaction rule, which determines how agents update their own opinion, and (2) the network topology, which defines the possible interaction among agents. In this work, we show that the third degree of freedom exists. This can be used to change a model's output up to 100% of its initial value or to transform two models (both from the literature) into each other. Since opinion dynamics models are representations of the real world, it is fundamental to understand how people’s opinions can be measured. Even for abstract models (i.e., not intended for the fitting of real-world data), it is important to understand if the way of numerically representing opinions is unique; and, if this is not the case, how the model dynamics would change by using different representations. The process of measuring opinions is non-trivial as it requires transforming real-world opinion (e.g., supporting most of the liberal ideals) to a number. Such a process is usually not discussed in opinion dynamics literature, but it has been intensively studied in a subfield of psychology called psychometrics. In psychometrics, opinion scales can be converted into each other, similarly to how meters can be converted to feet. Indeed, psychometrics routinely uses both linear and non-linear transformations of opinion scales. Here, we analyze how this transformation affects opinion dynamics models. We analyze this effect by using mathematical modeling and then validating our analysis with agent-based simulations. Firstly, we study the case of perfect scales. In this way, we show that scale transformations affect the model’s dynamics up to a qualitative level. This means that if two researchers use the same opinion dynamics model and even the same dataset, they could make totally different predictions just because they followed different renormalization processes. A similar situation appears if two different scales are used to measure opinions even on the same population. This effect may be as strong as providing an uncertainty of 100% on the simulation’s output (i.e., all results are possible). Still, by using perfect scales, we show that scales transformations can be used to perfectly transform one model to another. We test this using two models from the standard literature. Finally, we test the effect of scale transformation in the case of finite precision using a 7-points Likert scale. In this way, we show how a relatively small-scale transformation introduces both changes at the qualitative level (i.e., the most shared opinion at the end of the simulation) and in the number of opinion clusters. Thus, scale transformation appears to be a third degree of freedom of opinion dynamics models. This result deeply impacts both theoretical research on models' properties and on the application of models on real-world data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=degrees%20of%20freedom" title="degrees of freedom">degrees of freedom</a>, <a href="https://publications.waset.org/abstracts/search?q=empirical%20validation" title=" empirical validation"> empirical validation</a>, <a href="https://publications.waset.org/abstracts/search?q=opinion%20scale" title=" opinion scale"> opinion scale</a>, <a href="https://publications.waset.org/abstracts/search?q=opinion%20dynamics" title=" opinion dynamics"> opinion dynamics</a> </p> <a href="https://publications.waset.org/abstracts/132461/adding-a-degree-of-freedom-to-opinion-dynamics-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132461.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">119</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">1404</span> Freedom of Information and Freedom of Expression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amin%20Pashaye%20Amiri">Amin Pashaye Amiri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Freedom of information, according to which the public has a right to have access to government-held information, is largely considered as a tool for improving transparency and accountability in governments, and as a requirement of self-governance and good governance. So far, more than ninety countries have recognized citizens’ right to have access to public information. This recognition often took place through the adoption of an act referred to as “freedom of information act”, “access to public records act”, and so on. A freedom of information act typically imposes a positive obligation on a government to initially and regularly release certain public information, and also obliges it to provide individuals with information they request. Such an act usually allows governmental bodies to withhold information only when it falls within a limited number of exemptions enumerated in the act such as exemptions for protecting privacy of individuals and protecting national security. Some steps have been taken at the national and international level towards the recognition of freedom of information as a human right. Freedom of information was recognized in a few countries as a part of freedom of expression, and therefore, as a human right. Freedom of information was also recognized by some international bodies as a human right. The Inter-American Court of Human Rights ruled in 2006 that Article 13 of the American Convention on Human Rights, which concerns the human right to freedom of expression, protects the right of all people to request access to government information. The European Court of Human Rights has recently taken a considerable step towards recognizing freedom of information as a human right. However, in spite of the measures that have been taken, public access to government information is not yet widely accepted as an international human right. The paper will consider the degree to which freedom of information has been recognized as a human right, and study the possibility of widespread recognition of such a human right in the future. It will also examine the possible benefits of such recognition for the development of the human right to free expression. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=freedom%20of%20information" title="freedom of information">freedom of information</a>, <a href="https://publications.waset.org/abstracts/search?q=freedom%20of%20expression" title=" freedom of expression"> freedom of expression</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20rights" title=" human rights"> human rights</a>, <a href="https://publications.waset.org/abstracts/search?q=government%20information" title=" government information"> government information</a> </p> <a href="https://publications.waset.org/abstracts/23647/freedom-of-information-and-freedom-of-expression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23647.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">548</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">1403</span> Locomotion Effects of Redundant Degrees of Freedom in Multi-Legged Quadruped Robots</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Keshavarz">Hossein Keshavarz</a>, <a href="https://publications.waset.org/abstracts/search?q=Alejandro%20Ramirez-Serrano"> Alejandro Ramirez-Serrano</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Energy efficiency and locomotion speed are two key parameters for legged robots; thus, finding ways to improve them are important. This paper proposes a locomotion framework to analyze the energy usage and speed of quadruped robots via a Genetic Algorithm (GA) optimization process. For this, a quadruped robot platform with joint redundancy in its hind legs that we believe will help multi-legged robots improve their speed and energy consumption is used. ContinuO, the quadruped robot of interest, has 14 active degrees of freedom (DoFs), including three DoFs for each front leg, and unlike previously developed quadruped robots, four DoFs for each hind leg. ContinuO aims to realize a cost-effective quadruped robot for real-world scenarios with high speeds and the ability to overcome large obstructions. The proposed framework is used to locomote the robot and analyze its energy consumed at diverse stride lengths and locomotion speeds. The analysis is performed by comparing the obtained results in two modes, with and without the joint redundancy on the robot’s hind legs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm%20optimization" title="genetic algorithm optimization">genetic algorithm optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=locomotion%20path%20planning" title=" locomotion path planning"> locomotion path planning</a>, <a href="https://publications.waset.org/abstracts/search?q=quadruped%20robots" title=" quadruped robots"> quadruped robots</a>, <a href="https://publications.waset.org/abstracts/search?q=redundant%20legs" title=" redundant legs"> redundant legs</a> </p> <a href="https://publications.waset.org/abstracts/172914/locomotion-effects-of-redundant-degrees-of-freedom-in-multi-legged-quadruped-robots" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172914.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">1402</span> Developing A Third Degree Of Freedom For Opinion Dynamics Models Using Scales</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dino%20Carpentras">Dino Carpentras</a>, <a href="https://publications.waset.org/abstracts/search?q=Alejandro%20Dinkelberg"> Alejandro Dinkelberg</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Quayle"> Michael Quayle</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Opinion dynamics models use an agent-based modeling approach to model people’s opinions. Model's properties are usually explored by testing the two 'degrees of freedom': the interaction rule and the network topology. The latter defines the connection, and thus the possible interaction, among agents. The interaction rule, instead, determines how agents select each other and update their own opinion. Here we show the existence of the third degree of freedom. This can be used for turning one model into each other or to change the model’s output up to 100% of its initial value. Opinion dynamics models represent the evolution of real-world opinions parsimoniously. Thus, it is fundamental to know how real-world opinion (e.g., supporting a candidate) could be turned into a number. Specifically, we want to know if, by choosing a different opinion-to-number transformation, the model’s dynamics would be preserved. This transformation is typically not addressed in opinion dynamics literature. However, it has already been studied in psychometrics, a branch of psychology. In this field, real-world opinions are converted into numbers using abstract objects called 'scales.' These scales can be converted one into the other, in the same way as we convert meters to feet. Thus, in our work, we analyze how this scale transformation may affect opinion dynamics models. We perform our analysis both using mathematical modeling and validating it via agent-based simulations. To distinguish between scale transformation and measurement error, we first analyze the case of perfect scales (i.e., no error or noise). Here we show that a scale transformation may change the model’s dynamics up to a qualitative level. Meaning that a researcher may reach a totally different conclusion, even using the same dataset just by slightly changing the way data are pre-processed. Indeed, we quantify that this effect may alter the model’s output by 100%. By using two models from the standard literature, we show that a scale transformation can transform one model into the other. This transformation is exact, and it holds for every result. Lastly, we also test the case of using real-world data (i.e., finite precision). We perform this test using a 7-points Likert scale, showing how even a small scale change may result in different predictions or a number of opinion clusters. Because of this, we think that scale transformation should be considered as a third-degree of freedom for opinion dynamics. Indeed, its properties have a strong impact both on theoretical models and for their application to real-world data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=degrees%20of%20freedom" title="degrees of freedom">degrees of freedom</a>, <a href="https://publications.waset.org/abstracts/search?q=empirical%20validation" title=" empirical validation"> empirical validation</a>, <a href="https://publications.waset.org/abstracts/search?q=opinion%20scale" title=" opinion scale"> opinion scale</a>, <a href="https://publications.waset.org/abstracts/search?q=opinion%20dynamics" title=" opinion dynamics"> opinion dynamics</a> </p> <a href="https://publications.waset.org/abstracts/132446/developing-a-third-degree-of-freedom-for-opinion-dynamics-models-using-scales" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132446.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">155</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">1401</span> Effective Charge Coupling in Low Dimensional Doped Quantum Antiferromagnets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suraka%20Bhattacharjee">Suraka Bhattacharjee</a>, <a href="https://publications.waset.org/abstracts/search?q=Ranjan%20Chaudhury"> Ranjan Chaudhury</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The interaction between the charge degrees of freedom for itinerant antiferromagnets is investigated in terms of generalized charge stiffness constant corresponding to nearest neighbour t-J model and t1-t2-t3-J model. The low dimensional hole doped antiferromagnets are the well known systems that can be described by the t-J-like models. Accordingly, we have used these models to investigate the fermionic pairing possibilities and the coupling between the itinerant charge degrees of freedom. A detailed comparison between spin and charge couplings highlights that the charge and spin couplings show very similar behaviour in the over-doped region, whereas, they show completely different trends in the lower doping regimes. Moreover, a qualitative equivalence between generalized charge stiffness and effective Coulomb interaction is also established based on the comparisons with other theoretical and experimental results. Thus it is obvious that the enhanced possibility of fermionic pairing is inherent in the reduction of Coulomb repulsion with increase in doping concentration. However, the increased possibility can not give rise to pairing without the presence of any other pair producing mechanism outside the t-J model. Therefore, one can conclude that the t-J-like models themselves solely are not capable of producing conventional momentum-based superconducting pairing on their own. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=generalized%20charge%20stiffness%20constant" title="generalized charge stiffness constant">generalized charge stiffness constant</a>, <a href="https://publications.waset.org/abstracts/search?q=charge%20coupling" title=" charge coupling"> charge coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=effective%20Coulomb%20interaction" title=" effective Coulomb interaction"> effective Coulomb interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=t-J-like%20models" title=" t-J-like models"> t-J-like models</a>, <a href="https://publications.waset.org/abstracts/search?q=momentum-space%20pairing" title=" momentum-space pairing"> momentum-space pairing</a> </p> <a href="https://publications.waset.org/abstracts/111537/effective-charge-coupling-in-low-dimensional-doped-quantum-antiferromagnets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111537.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">159</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">1400</span> A Review on the Problems of Constructing a Theory of Quantum Gravity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amber%20Jamal">Amber Jamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Imran%20Siddiqui"> Imran Siddiqui</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Tanveer%20Iqbal"> Syed Tanveer Iqbal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This review is aimed to shed some light on problems constructing a theory of spacetime and geometry in terms of all quantum degrees of freedom called ‘Quantum Gravity’. Such a theory, which is effective at all scales of distances and energies, describes the enigma of the beginning of the Universe, its possible end, and reducing to general relativity at large distances but in a semi-classical approximation. Furthermore, the theory of quantum gravity also describes the Universe as a whole and provides a description of most fundamental questions that have puzzled scientists for decades, such as: what is space, what is time, and what is the fundamental structure of the Universe, is the spacetime discrete, if it is, where does the continuum of spacetime come from at low energies and macroscopic scales and where does it emerge from its fundamentally discrete building blocks? Quantum Field Theory (QFT) is a framework which describes the microscopic properties and dynamics of the basic building blocks of any condensed matter system. In QFT, atoms are quanta of continuous fields. At smaller scales or higher energies, the continuum description of spacetime fails. Therefore, a new description is required in terms of microscopic constituents (atoms or molecules). The objective of this scientific endeavor is to discuss the above-mentioned problems rigorously and to discuss possible way-out of the problems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=QFT" title="QFT">QFT</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20degrees%20of%20freedom" title=" quantum degrees of freedom"> quantum degrees of freedom</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20gravity" title=" quantum gravity"> quantum gravity</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-classical%20approximation" title=" semi-classical approximation"> semi-classical approximation</a> </p> <a href="https://publications.waset.org/abstracts/130610/a-review-on-the-problems-of-constructing-a-theory-of-quantum-gravity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130610.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">119</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">1399</span> Two Spherical Three Degrees of Freedom Parallel Robots 3-RCC and 3-RRS Static Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Abbasi%20Moshaii">Alireza Abbasi Moshaii</a>, <a href="https://publications.waset.org/abstracts/search?q=Shaghayegh%20Nasiri"> Shaghayegh Nasiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Tale%20Masouleh"> Mehdi Tale Masouleh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purpose of this study is static analysis of two three-degree of freedom parallel mechanisms: 3-RCC and 3-RRS. Geometry of these mechanisms is expressed and static equilibrium equations are derived for the whole chains. For these mechanisms due to the equal number of equations and unknowns, the solution is as same as 3-RCC mechanism. Mathematical software is used to solve the equations. In order to prove the results obtained from solving the equations of mechanisms, their CAD model has been simulated and their static is analysed in ADAMS software. Due to symmetrical geometry of the mechanisms, the force and external torque acting on the end-effecter have been considered asymmetric to prove the generality of the solution method. Finally, the results of both softwares, for both mechanisms are extracted and compared as graphs. The good achieved comparison between the results indicates the accuracy of the analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=robotic" title="robotic">robotic</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20analysis" title=" static analysis"> static analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=3-RCC" title=" 3-RCC"> 3-RCC</a>, <a href="https://publications.waset.org/abstracts/search?q=3-RRS" title=" 3-RRS"> 3-RRS</a> </p> <a href="https://publications.waset.org/abstracts/24128/two-spherical-three-degrees-of-freedom-parallel-robots-3-rcc-and-3-rrs-static-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24128.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">384</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">1398</span> Multi-Channel Charge-Coupled Device Sensors Real-Time Cell Growth Monitor System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Han-Wei%20Shih">Han-Wei Shih</a>, <a href="https://publications.waset.org/abstracts/search?q=Yao-Nan%20Wang"> Yao-Nan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ko-Tung%20Chang"> Ko-Tung Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Lung-Ming%20Fu"> Lung-Ming Fu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A multi-channel cell growth real-time monitor and evaluation system using charge-coupled device (CCD) sensors with 40X lens integrating a NI LabVIEW image processing program is proposed and demonstrated.

Most vibrations are undesirable and can cause damages to the buildings, machines and people all around us. The vibration wave from earthquakes, construction and winds have high potential to bring damage to the buildings. Excessive vibrations can result in structural and machinery failures. This failure is related to the human life and environment around it. The effect of vibration which causes failure and damage to the high rise buildings can be controlled in real life by implementing tuned mass damper (TMD) into the structure of the buildings. This research aims to study the effect and performance improvement achieved by applying TMD into the building structure. A structure model of three degrees of freedom (3DOF) is designed to demonstrate the performance of TMD to the designed model. The model designed is the physical representation of actual building structure in real life. It is constructed at a reduced scale and will be used for the experiment. Thus, the result obtained will be more accurate to compared with the real life effect. Based on the result from experimental study, by applying TMD to the structure model, the forces of vibration and the displacement mode of the building reduced. Thus, the reduced in vibration of the building helps to maintain the good condition of the building. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=degrees-of-freedom" title="degrees-of-freedom">degrees-of-freedom</a>, <a href="https://publications.waset.org/abstracts/search?q=displacement%20mode" title=" displacement mode"> displacement mode</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20frequency" title=" natural frequency"> natural frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=tuned%20mass%20damper" title=" tuned mass damper"> tuned mass damper</a> </p> <a href="https://publications.waset.org/abstracts/63247/high-rise-building-vibration-control-using-tuned-mass-damper" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63247.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">340</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">1396</span> Challenges to Press Freedom in Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Awais%20Ahmad">Awais Ahmad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> People of Khyber Pakhtunkhwa (KP) and Federally Administered Tribal Areas (FATA) remains underrepresented in Pakistan’s mainstream media and their miseries and concerns are unheard and unnoticed. Rising the incidents of human rights violation in KP province of Pakistan, and its absence in the mainstream media has raised many questions on the clause of press freedom known as 19/A in the constitution of Pakistan, that has claimed freedom of speech to all Pakistani citizens. Using a ‘think a loud’ research technique, senior most journalists of KP have been interviewed to get to know reasons of why and how Pashtun’s voices have been silenced in a democratic country where individual’s opinion is considered more powerful, and they can exercise freedom to protest and speak-up for their rights. The information collected from the journalists has been used to evaluate press freedom in KP and FATA by applying the institutional theory. The paper evaluates different recent cases where Pashtun journalists, media outlets and social activists were being punished for criticizing authorities and military establishment.

This paper describes how the logic synthesis techniques, such as 1) XOR detection, 2) logic doubling, 3) complement of a Boolean function are combined, applied and used to optimize the CPLDs devices architecture that is based on PAL-like macrocells. Our goal is to use these techniques for minimizing the number of macrocells required to implement a circuit and minimize the delay of mapped circuit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CPLD" title="CPLD">CPLD</a>, <a href="https://publications.waset.org/abstracts/search?q=doubling" title=" doubling"> doubling</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=XOR" title=" XOR"> XOR</a> </p> <a href="https://publications.waset.org/abstracts/8359/intelligent-and-optimized-placement-for-cpld-devices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8359.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">282</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">1394</span> The Dialectic of Law and Politics for George Friedrich Wilhelm Hegel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Djehich%20Mohamed%20Yousri">Djehich Mohamed Yousri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to address the dialectic of law and politics in the philosophy of the state of the philosopher Hegel by addressing the concept of law, which refers to its general meaning to the set of rules and legislation that man sets to apply them within society, as it is considered one of the primary and necessary conditions for the functioning of And organizing social life, when it defines the rights and duties of every individual belonging to the state, by approaching it with central concepts in political philosophy, such as the state, freedom and the people. The most prominent result that we reached through our analysis of the details of the problematic research is the relationship between law and politics in the philosophical system of Hegel; on the one hand, We find that the state is rational only to the extent that it resorts to the law and works under it, and the latter does not realize its essence and effectiveness unless it is extracted from the customs, traditions, and culture of the people so that it does not conflict with the ideal goal of its existence, which is to achieve freedom and protect it from all possible. A state does not mean at all to reduce the freedom of the people, so there is no conflict between law and freedom. <p class="card-text"><strong>Keywords:</strong> <a
