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">3313</span> Theoretical Investigation on the Dynamic Characteristics of One Degree of Freedom Vibration System Equipped with Inerter of Variable Inertance</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=Yoshiki%20Tsuji"> Yoshiki Tsuji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a theoretical investigation on the dynamic characteristics of one degree of freedom vibration system equipped with inerter of variable inertance, is presented.

Influence of inertance on the amplitude of vibration, phase angle, natural frequency, damping ratio, and logarithmic decrement was clarified. It was mainly found that the inerter decreases the natural frequency of the undamped system and also of the damped system if the damping ratio is below 0.707. On the other hand, the inerter increases the natural frequency of the damped system if the damping ratio exceeds 0.707.

Studies in earthquake resistant buildings, fire, and explosion resistant buildings now dominate the arena. To protect people and facilities from the effects of the explosion, reinforced concrete walls have been designed to be blast resistant. Understanding the performance of these walls is a key step in ensuring the safety of built facilities. Blast walls are mostly designed using simple techniques such as single degree of freedom (SDOF) method, despite the increasing use of multi-degree of freedom techniques such as the finite element method. This study is the first stage of a continuous research into the safety and reliability of blast walls. It presents the SDOF approach applied to the analysis of a concrete wall panel under three representative bomb situations. These are motorcycle 50 kg, car 400kg and also van with the capacity of 1500 kg of TNT explosive. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20wall" title="blast wall">blast wall</a>, <a href="https://publications.waset.org/abstracts/search?q=safety" title=" safety"> safety</a>, <a href="https://publications.waset.org/abstracts/search?q=protection" title=" protection"> protection</a>, <a href="https://publications.waset.org/abstracts/search?q=explosion" title=" explosion"> explosion</a> </p> <a href="https://publications.waset.org/abstracts/65519/safety-of-built-infrastructure-single-degree-of-freedom-approach-to-blast-resistant-rc-wall-panels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65519.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">263</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">3311</span> Theoretical Study on the Forced Vibration of One Degree of Freedom System, Equipped with Inerter, under Load-Type or Displacement-Type Excitation</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> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a theoretical study on the forced vibration of one degree of freedom system equipped with inerter, working under load-type or displacement-type excitation, is presented. Differential equations of movement are solved under cosinusoidal excitation, and explicit relations for the magnitude, resonant magnitude, phase angle, resonant frequency, and critical frequency are obtained. Influence of the inertance and damping on these dynamic characteristics is clarified. From the obtained results, one concludes that the inerter increases the magnitude of vibration and the phase angle of the damped mechanical system. Moreover, the magnitude ratio and difference of phase angles are not depending on the actual type of excitation. Consequently, such kind of similitude allows for the comparison of various theoretical and experimental results, which can be broadly found in the literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=displacement-type%20excitation" title="displacement-type excitation">displacement-type excitation</a>, <a href="https://publications.waset.org/abstracts/search?q=inerter" title=" inerter"> inerter</a>, <a href="https://publications.waset.org/abstracts/search?q=load-type%20excitation" title=" load-type excitation"> load-type excitation</a>, <a href="https://publications.waset.org/abstracts/search?q=one%20degree%20of%20freedom%20vibration" title=" one degree of freedom vibration"> one degree of freedom vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20connection" title=" parallel connection"> parallel connection</a> </p> <a href="https://publications.waset.org/abstracts/90102/theoretical-study-on-the-forced-vibration-of-one-degree-of-freedom-system-equipped-with-inerter-under-load-type-or-displacement-type-excitation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90102.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">216</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">3310</span> Two Degree of Freedom Spherical Mechanism Design for Exact Sun Tracking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Osman%20Acar">Osman Acar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sun tracking systems are the systems following the sun ray by a right angle or by predetermined certain angle.

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">3306</span> Seismic Reliability of Two-DegreE-of-Freedom Systems with Supplemental Damping</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.D.%20Garc%C3%ADa-Soto">A.D.

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. This presentation will focus on a case study of a university’s effort to develop an updated, evolving policy on academic freedom that provides a framework and remedies for contemporary challenges to this critical function in higher education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20freedom" title="academic freedom">academic freedom</a>, <a href="https://publications.waset.org/abstracts/search?q=academic%20freedom%20policy" title=" academic freedom policy"> academic freedom policy</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education%20policy" title=" higher education policy"> higher education policy</a> </p> <a href="https://publications.waset.org/abstracts/139552/academic-freedom-policy-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139552.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">199</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">3304</span> An Optimized Method for Calculating the Linear and Nonlinear Response of SDOF System Subjected to an Arbitrary Base Excitation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Kabir">Hossein Kabir</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Sadeghi"> Mojtaba Sadeghi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Finding the linear and nonlinear responses of a typical single-degree-of-freedom system (SDOF) is always being regarded as a time-consuming process.

Using the dynamical cluster-decay model (DCM) with Φ degree-of-freedom included, we have studied three compound systems 246Bk&lowast;, 164Yb&lowast; and 105Ag&lowast;. Here, within the DCM with pocket formula for nuclear proximity potential, we look for the effects of including compact, non-coplanar configurations (Φc = 00) on the non-compound nucleus (nCN) contribution in total fusion cross section σfus. For 246Bk&lowast;, formed in 11B+235U and 14N+232Th reaction channels, the DCM with coplanar nuclei (Φc = 00) shows an nCN contribution for 11B+235U channel, but none for 14N+232Th channel, which on including Φ gives both reaction channels as pure compound nucleus decays. In the case of 164Yb&lowast;, formed in 64Ni+100Mo, the small nCN effects for Φ=00 are reduced to almost zero for Φ = 00. Interestingly, however, 105Ag&lowast; for Φ = 00 shows a small nCN contribution, which gets strongly enhanced for Φ = 00, such that the characteristic property of PCN presents a change of behaviour, like that of a strongly fissioning superheavy element to a weakly fissioning nucleus; note that 105Ag&lowast; is a weakly fissioning nucleus and Psurv behaves like one for a weakly fissioning nucleus for both Φ = 00 and Φ = 00. Apparently, Φ is presenting itself like a good degree-of-freedom in the DCM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamical%20cluster-decay%20model" title="dynamical cluster-decay model">dynamical cluster-decay model</a>, <a href="https://publications.waset.org/abstracts/search?q=fusion%20cross%20sections" title=" fusion cross sections"> fusion cross sections</a>, <a href="https://publications.waset.org/abstracts/search?q=non-compound%20nucleus%20effects" title=" non-compound nucleus effects"> non-compound nucleus effects</a>, <a href="https://publications.waset.org/abstracts/search?q=non-coplanarity" title=" non-coplanarity"> non-coplanarity</a> </p> <a href="https://publications.waset.org/abstracts/41851/non-coplanar-nuclei-in-heavy-ion-reactions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41851.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">302</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">3302</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.

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">3300</span> Weighted G2 Multi-Degree Reduction of Bezier Curves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salisu%20ibrahim">Salisu ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdalla%20Rababah"> Abdalla Rababah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research, we use Weighted G2-Multi-degree reduction of Bezier curve of degree n to a Bezier curve of degree m, m < n.

The time when the robot returns to its initial position after an interaction and the primary resistance of the robot against the impact must be reduced. Thus, the applied torque on the motor will be reduced. The impedance control is an appropriate method for robot control in these conditions. The stability of the robot at interaction moment was transformed to be a robust stability problem. The dynamic of the unknown environment was modeled as a weight function and the stability of the robot under an interaction with the environment has been investigated using the robust control concept. To improve the performance of the system, a force controller has been designed which the normalized impedance after interaction has been reduced. The resistance of the robot has been considered as a normalized cost function and its value was 0.593. The results has showed reduction of resistance of the robot against impact and the reduction of convergence time by lower than one second. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=impedance%20control" title="impedance control">impedance control</a>, <a href="https://publications.waset.org/abstracts/search?q=control%20system" title=" control system"> control system</a>, <a href="https://publications.waset.org/abstracts/search?q=robots" title=" robots"> robots</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction" title=" interaction"> interaction</a> </p> <a href="https://publications.waset.org/abstracts/15189/stability-and-performance-improvement-of-a-two-degree-of-freedom-robot-under-interaction-using-the-impedance-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15189.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">430</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">3298</span> Modeling of Complex Structures: Shear Wall with Openings and Stiffened Shells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Temami%20Oussama">Temami Oussama</a>, <a href="https://publications.waset.org/abstracts/search?q=Bessais%20Lakhdar"> Bessais Lakhdar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamadi%20Djamal"> Hamadi Djamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Abderrahmani%20Sifeddine"> Abderrahmani Sifeddine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The analysis of complex structures encourages the engineer to make simplifying assumptions, sometimes attempting the analysis of the whole structure as complex as it is, and it can be done using the finite element method (FEM). 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.

In this paper, while presenting motion equations with six degrees of freedom for Autonomous Underwater Vehicles, Proportional Navigation Guidance Law and the first order sliding mode control for TAIPAN AUV was used to address its guidance for the purpose of collision with a moving target. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Autonomous%20Underwater%20Vehicle%20%28AUV%29" title="Autonomous Underwater Vehicle (AUV)">Autonomous Underwater Vehicle (AUV)</a>, <a href="https://publications.waset.org/abstracts/search?q=degree%20of%20freedom%20%28DOF%29" title=" degree of freedom (DOF)"> degree of freedom (DOF)</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrodynamic" title=" hydrodynamic"> hydrodynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=line%20of%20sight%28LOS%29" title=" line of sight(LOS)"> line of sight(LOS)</a>, <a href="https://publications.waset.org/abstracts/search?q=proportional%20navigation%20guidance%28PNG%29" title=" proportional navigation guidance(PNG)"> proportional navigation guidance(PNG)</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20mode%20control%28SMC%29" title=" sliding mode control(SMC) "> sliding mode control(SMC) </a> </p> <a href="https://publications.waset.org/abstracts/17056/guidance-and-control-of-a-torpedo-autonomous-underwater-vehicle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17056.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">468</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">3296</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 study also explores that the perception of local journalists regarding press freedom and what are the factors they consider it restrictions while they perform their duties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=press%20freedom" title="press freedom">press freedom</a>, <a href="https://publications.waset.org/abstracts/search?q=federally%20administered%20tribal%20areas%20%28fata%29" title=" federally administered tribal areas (fata)"> federally administered tribal areas (fata)</a>, <a href="https://publications.waset.org/abstracts/search?q=khyber%20pakhtunkhwa%20%28kp%29" title=" khyber pakhtunkhwa (kp)"> khyber pakhtunkhwa (kp)</a>, <a href="https://publications.waset.org/abstracts/search?q=military%20establishment" title=" military establishment"> military establishment</a> </p> <a href="https://publications.waset.org/abstracts/167654/challenges-to-press-freedom-in-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167654.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">67</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">3295</span> Adding a Degree of Freedom to Opinion Dynamics Models </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> Within agent-based modeling, opinion dynamics is the field that focuses on modeling people's opinions. 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">3294</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 href="https://publications.waset.org/abstracts/search?q=hegel" title="hegel">hegel</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20law" title=" the law"> the law</a>, <a href="https://publications.waset.org/abstracts/search?q=country" title=" country"> country</a>, <a href="https://publications.waset.org/abstracts/search?q=freedom" title=" freedom"> freedom</a>, <a href="https://publications.waset.org/abstracts/search?q=citizen" title=" citizen"> citizen</a> </p> <a href="https://publications.waset.org/abstracts/161831/the-dialectic-of-law-and-politics-for-george-friedrich-wilhelm-hegel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161831.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">85</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">3293</span> The Ordinary Way of the Appeal in Penalty Part</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelkadir%20Elhaouari">Abdelkadir Elhaouari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The priciest thing in human life since his birth is his freedom, basing on this idea, the conflict exists till now, the fight against oppression, injustice, tyranny and slavery, searching for freedom and political resistances, and this makes the freedom is deeply related to the defense for its existence all over years.

The vagueness of the definitions of the terms used in these laws makes them inconsistent with the provisions of the right to freedom of religion guaranteed by the Constitution. It is a critical question whether these laws protect the religious freedom of groups that are “vulnerable” to missionary inducements, or are they restricting the freedom of citizens to propagate their religion to others or change their religious identity? This article looks into the constitutionality of the anti-conversion laws passed in the Indian States and argues that these laws limit the freedom of religion guaranteed under Article 25 of the Constitution of India. The ambiguity in the anti-conversion laws passed in various states of India is brought out by critically analyzing multiple cases charged under anti-conversion laws. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Freedom%20of%20Religion" title="Freedom of Religion">Freedom of Religion</a>, <a href="https://publications.waset.org/abstracts/search?q=Anti-conversion%20Laws" title=" Anti-conversion Laws"> Anti-conversion Laws</a>, <a href="https://publications.waset.org/abstracts/search?q=allurement" title=" allurement"> allurement</a>, <a href="https://publications.waset.org/abstracts/search?q=inducement" title=" inducement"> inducement</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20fraudulent%20means." title=" and fraudulent means."> and fraudulent means.</a> </p> <a href="https://publications.waset.org/abstracts/154609/ambiguity-in-anti-conversion-laws-in-the-indian-states-a-limitation-to-the-freedom-of-religion-guaranteed-under-the-constitution-of-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154609.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">106</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">3291</span> Maximum Deformation Estimation for Reinforced Concrete Buildings Using Equivalent Linearization Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chien-Kuo%20Chiu">Chien-Kuo Chiu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the displacement-based seismic design and evaluation, equivalent linearization method is one of the approximation methods to estimate the maximum inelastic displacement response of a system. In this study, the accuracy of two equivalent linearization methods are investigated. The investigation consists of three soil condition in Taiwan (Taipei Basin 1, 2, and 3) and five different heights of building (H_r= 10, 20, 30, 40, and 50 m). The first method is the Taiwan equivalent linearization method (TELM) which was proposed based on Japanese equivalent linear method considering the modification factor, α_T= 0.85. On the basis of Lin and Miranda study, the second method is proposed with some modification considering Taiwan soil conditions. From this study, it is shown that Taiwanese equivalent linearization method gives better estimation compared to the modified Lin and Miranda method (MLM). The error index for the Taiwanese equivalent linearization method are 16%, 13%, and 12% for Taipei Basin 1, 2, and 3, respectively. Furthermore, a ductility demand spectrum of single-degree-of-freedom (SDOF) system is presented in this study as a guide for engineers to estimate the ductility demand of a structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=displacement-based%20design" title="displacement-based design">displacement-based design</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility%20demand%20spectrum" title=" ductility demand spectrum"> ductility demand spectrum</a>, <a href="https://publications.waset.org/abstracts/search?q=equivalent%20linearization%20method" title=" equivalent linearization method"> equivalent linearization method</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20buildings" title=" RC buildings"> RC buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=single-degree-of-freedom" title=" single-degree-of-freedom"> single-degree-of-freedom</a> </p> <a href="https://publications.waset.org/abstracts/91802/maximum-deformation-estimation-for-reinforced-concrete-buildings-using-equivalent-linearization-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91802.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">3290</span> Model Based Fault Diagnostic Approach for Limit Switches</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zafar%20Mahmood">Zafar Mahmood</a>, <a href="https://publications.waset.org/abstracts/search?q=Surayya%20Naz"> Surayya Naz</a>, <a href="https://publications.waset.org/abstracts/search?q=Nazir%20Shah%20Khattak"> Nazir Shah Khattak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The degree of freedom relates to our capability to observe or model the energy paths within the system. Higher the number of energy paths being modeled leaves to us a higher degree of freedom, but increasing the time and modeling complexity rendering it useless for today’s world’s need for minimum time to market. Since the number of residuals that can be uniquely isolated are dependent on the number of independent outputs of the system, increasing the number of sensors required. The examples of discrete position sensors that may be used to form an array include limit switches, Hall effect sensors, optical sensors, magnetic sensors, etc. Their mechanical design can usually be tailored to fit in the transitional path of an STME in a variety of mechanical configurations. The case studies into multi-sensor system were carried out and actual data from sensors is used to test this generic framework. It is being investigated, how the proper modeling of limit switches as timing sensors, could lead to unified and neutral residual space while keeping the implementation cost reasonably low. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low-cost%20limit%20sensors" title="low-cost limit sensors">low-cost limit sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=fault%20diagnostics" title=" fault diagnostics"> fault diagnostics</a>, <a href="https://publications.waset.org/abstracts/search?q=Single%20Throw%20Mechanical%20Equipment%20%28STME%29" title=" Single Throw Mechanical Equipment (STME)"> Single Throw Mechanical Equipment (STME)</a>, <a href="https://publications.waset.org/abstracts/search?q=parameter%20estimation" title=" parameter estimation"> parameter estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=parity-space" title=" parity-space"> parity-space</a> </p> <a href="https://publications.waset.org/abstracts/25825/model-based-fault-diagnostic-approach-for-limit-switches" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25825.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">617</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">3289</span> Economic Analysis of Interaction Freedom, Institutions and Development in the countries of North Africa: Amartya Sen Approach of Capability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Essardi%20Omar">Essardi Omar</a>, <a href="https://publications.waset.org/abstracts/search?q=Razzouk%20Redouane"> Razzouk Redouane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The concept of freedom requires notice of countries all over the world to consider welfare and the quality of life.

Indeed, with an approach based on the correlation and the analysis of data, particularly on the tool of principle component analysis, we are going to study assessments of World Bank, Freedom House, Fraster institute, and MINEFE experts. Our empirical objective is to reveal the existence of the institutional and freedom characteristics related to the development of the emergent countries. In order to help us to explain the recent performance reached by Central and Eastern Europe and Latine America in compared with the case of countries of North Africa.

The news sentiment ratio is calculated by using the content analysis of semantic orientation. The empirical results show that news released prior to the event date may decrease the cumulative abnormal returns prior to the earnings announcement regardless of whether it is released in China or Taiwan. By contrast, companies with optimistic financial news may increase the cumulative abnormal returns during the announcement date. Furthermore, the difference in terms of press freedom is considered in greater China to compare the impact of press freedom on abnormal returns. The findings show that, the freer the press is, the more negatively significant will be the impact of news on the abnormal returns, which means that the press freedom may decrease the ability of the news to impact the abnormal returns. The intuition is that investors may receive alternative news related to each company in the market with greater press freedom, which proves the efficiency of the market and reduces the possible excess returns. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=news" title="news">news</a>, <a href="https://publications.waset.org/abstracts/search?q=press%20freedom" title=" press freedom"> press freedom</a>, <a href="https://publications.waset.org/abstracts/search?q=Greater%20China" title=" Greater China"> Greater China</a>, <a href="https://publications.waset.org/abstracts/search?q=earnings%20announcement" title=" earnings announcement"> earnings announcement</a>, <a href="https://publications.waset.org/abstracts/search?q=abnormal%20returns" title=" abnormal returns"> abnormal returns</a> </p> <a href="https://publications.waset.org/abstracts/8585/the-impact-of-financial-news-and-press-freedom-on-abnormal-returns-around-earnings-announcements-in-greater-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8585.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">393</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">3287</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.

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
