The food and energy related-economic sector has been subjected to negative consequences due to recent extreme changes in weather conditions, particularly in developing countries. Besides continuous modifications in weather, population is also increasing by time, therefore it is necessary to take special steps and start effective initiatives to cope with the challenges of food and energy security to fight hunger and for economic stability of country. Severe increase in temperature and heat waves has also negative impacts on food production as well as energy sustainability. Energy (in terms of electricity) consumption has grown up than the production potential of the country as a consequence of increasing warm weather. Ultimately prices gone up when there is more consumption than production. Therefore, all these aspects of climate change are interrelated with socio-economic issues. There is a need to develop long-term policies on regional and national levels for maintainable economic growth. This research presents a framework-plan and recommendations for implementation needed to mitigate the potential threats due to global climate change sustainable food and energy production under climate change in the country. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20changes" title="climate changes">climate changes</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20security" title=" energy security"> energy security</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20security" title=" food security"> food security</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20climate%20change" title=" global climate change"> global climate change</a> </p> <a href="https://publications.waset.org/abstracts/41467/impact-of-global-climate-change-on-economy-of-pakistan-how-to-ensure-sustainable-food-and-energy-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41467.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">350</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">8399</span> Relation between Initial Stability of the Dental Implant and Bone-Implant Contact Level</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jui-Ting%20Hsu">Jui-Ting Hsu</a>, <a href="https://publications.waset.org/abstracts/search?q=Heng-Li%20Huang"> Heng-Li Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming-Tzu%20Tsai"> Ming-Tzu Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuo-Chih%20Su"> Kuo-Chih Su</a>, <a href="https://publications.waset.org/abstracts/search?q=Lih-Jyh%20Fuh"> Lih-Jyh Fuh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objectives of this study were to measure the initial stability of the dental implant (ISQ and PTV) in the artificial foam bone block with three different quality levels.

Propagation patterns are closely linked to the structure of communities. This study proposes a method of community analysis based on a combination of centrality indicators for the network and its main communities. The objective is to establish a link between the stability of the communities over time, the social ascension of its members internally, and the propagation of information in the community. To this end, data from the debates about global warming and political communities on Twitter have been collected, and several tens of millions of tweets and retweets have helped us better understand the structure of these communities. The quantification of this stability allows for the study of the propagation of information of any kind, including disinformation. Our results indicate that the most stable communities over time are the ones that enable the establishment of nodes capturing a large part of the information and broadcasting its opinions. Conversely, communities with a high turnover and social ascendancy only stabilize themselves strongly in the face of adversity and external events but seem to offer a greater diversity of opinions most of the time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community%20analysis" title="community analysis">community analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=disinformation" title=" disinformation"> disinformation</a>, <a href="https://publications.waset.org/abstracts/search?q=misinformation" title=" misinformation"> misinformation</a>, <a href="https://publications.waset.org/abstracts/search?q=Twitter" title=" Twitter"> Twitter</a> </p> <a href="https://publications.waset.org/abstracts/128710/quantifying-stability-of-online-communities-and-its-impact-on-disinformation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128710.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">140</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">8397</span> Effect of Change in Angle of Slope and Height of an Embankment on Safety Factor during Rapid Drawdown</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Abolhassan%20Naeini">Seyed Abolhassan Naeini</a>, <a href="https://publications.waset.org/abstracts/search?q=Azam%20Kouhpeyma"> Azam Kouhpeyma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reduction of water level at which a slope is submerged with it is called drawdown. Draw down can took place rapidly or slowly and in both situations, it can affect slope stability. Using coupled analysis (seepage and stability analysis) causes more accurate results. In this study, the stability of homogeneous embankment is investigated numerically. Slope safety factor changes due to changes in three factors of height, slope and drawdown rate have been investigated and compared.

Also, we prove some results on uniform boundedness and uniform ultimate boundedness of solutions of systems of equations study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aizermann" title="Aizermann">Aizermann</a>, <a href="https://publications.waset.org/abstracts/search?q=boundedness" title=" boundedness"> boundedness</a>, <a href="https://publications.waset.org/abstracts/search?q=first%20order" title=" first order"> first order</a>, <a href="https://publications.waset.org/abstracts/search?q=Lyapunov%20function" title=" Lyapunov function"> Lyapunov function</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a> </p> <a href="https://publications.waset.org/abstracts/164909/stability-and-boundedness-theorems-of-solutions-of-certain-systems-of-differential-equations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164909.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">84</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8393</span> The Role of the Rate of Profit Concept in Creating Economic Stability in Islamic Financial Market</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Trisiladi%20Supriyanto">Trisiladi Supriyanto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to establish a concept of rate of profit on Islamic banking that can create economic justice and stability in the Islamic Financial Market (Banking and Capital Markets). A rate of profit that creates economic justice and stability can be achieved through its role in maintaining the stability of the financial system in which there is an equitable distribution of income and wealth. To determine the role of the rate of profit as the basis of the profit sharing system implemented in the Islamic financial system, we can see the connection of rate of profit in creating financial stability, especially in the asset-liability management of financial institutions that generate a stable net margin or the rate of profit that is not affected by the ups and downs of the market risk factors, including indirect effect on interest rates. Furthermore, Islamic financial stability can be seen from the role of the rate of profit on the stability of the Islamic financial assets value that are measured from the Islamic financial asset price volatility in the Islamic Bond Market in the Capital Market. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=economic%20justice" title="economic justice">economic justice</a>, <a href="https://publications.waset.org/abstracts/search?q=equitable%20distribution%20of%20income" title=" equitable distribution of income"> equitable distribution of income</a>, <a href="https://publications.waset.org/abstracts/search?q=equitable%20distribution%20of%20wealth" title=" equitable distribution of wealth"> equitable distribution of wealth</a>, <a href="https://publications.waset.org/abstracts/search?q=rate%20of%20profit" title=" rate of profit"> rate of profit</a>, <a href="https://publications.waset.org/abstracts/search?q=stability%20in%20the%20financial%20system" title=" stability in the financial system"> stability in the financial system</a> </p> <a href="https://publications.waset.org/abstracts/48161/the-role-of-the-rate-of-profit-concept-in-creating-economic-stability-in-islamic-financial-market" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48161.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">314</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">8392</span> Longitudinal Static and Dynamic Stability of a Typical Reentry Body in Subsonic Conditions Using Computational Fluid Dynamics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Jathaveda">M.

For a non-propulsive ballistic entry, static and dynamic stability play an important role in the trajectory, especially for the safe deployment of parachutes, typically at subsonic Mach numbers. Static stability of flight vehicles are being estimated through CFD techniques routinely. Advances in CFD software as well as computational facilities have enabled the estimation of the dynamic stability derivatives also through CFD techniques. Longitudinal static and dynamic stability of a typical reentry body for subsonic Mach number of 0.6 is predicted using commercial software CFD++ and presented here. Steady state simulations are carried out for α = 2° on an unstructured grid using SST k-ω model. Transient simulation using forced oscillation method is used to compute pitch damping derivatives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stability" title="stability">stability</a>, <a href="https://publications.waset.org/abstracts/search?q=typical%20reentry%20body" title=" typical reentry body"> typical reentry body</a>, <a href="https://publications.waset.org/abstracts/search?q=subsonic" title=" subsonic"> subsonic</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20and%20dynamic" title=" static and dynamic"> static and dynamic</a> </p> <a href="https://publications.waset.org/abstracts/159425/longitudinal-static-and-dynamic-stability-of-a-typical-reentry-body-in-subsonic-conditions-using-computational-fluid-dynamics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159425.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">115</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">8391</span> Stability of Out-Of-Plane Equilibrium Points in the Elliptic Restricted Three-Body Problem with Oblateness up to Zonal Harmonic J₄ of Both Primaries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kanshio%20Richard%20Tyokyaa">Kanshio Richard Tyokyaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Jagadish%20Singh"> Jagadish Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we examined the location and stability of Out-Of-Plane Equilibrium points in the elliptic restricted three-body problem of an infinitesimal body when both primaries are taken as oblate spheroids with oblateness up to zonal harmonic J₄.

The recorded data from a milling test cut is used to classify the cut as stable or unstable based on the frequency analysis.

Summers</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The advanced computational analysis of biological systems is becoming increasingly dependent upon an understanding of the information-theoretic structure of the materials, energy and interactive processes that comprise those systems. The stability and survival of these living systems are fundamentally contingent upon their ability to acquire and process the meaning of information concerning the physical state of its biological continuum (biocontinuum). The drive for adaptive system reconciliation of a divergence from steady-state within this biocontinuum can be described by an information metric-based formulation of the process for actionable knowledge acquisition that incorporates the axiomatic inference of Kullback-Leibler information minimization driven by survival replicator dynamics. If the mathematical expression of this process is the Lagrangian integrand for any change within the biocontinuum then it can also be considered as an action functional for the living system. In the direct method of Lyapunov, such a summarizing mathematical formulation of global system behavior based on the driving forces of energy currents and constraints within the system can serve as a platform for the analysis of stability. As the system evolves in time in response to biocontinuum perturbations, the summarizing function then conveys information about its overall stability. This stability information portends survival and therefore has absolute existential meaning for the living system. The first derivative of the Lyapunov energy information function will have a negative trajectory toward a system's steady state if the driving force is dissipating. By contrast, system instability leading to system dissolution will have a positive trajectory. The direction and magnitude of the vector for the trajectory then serves as a quantifiable signature of the meaning associated with the living system’s stability information, homeostasis and survival potential. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=meaning" title="meaning">meaning</a>, <a href="https://publications.waset.org/abstracts/search?q=information" title=" information"> information</a>, <a href="https://publications.waset.org/abstracts/search?q=Lyapunov" title=" Lyapunov"> Lyapunov</a>, <a href="https://publications.waset.org/abstracts/search?q=living%20systems" title=" living systems"> living systems</a> </p> <a href="https://publications.waset.org/abstracts/146575/quantifying-meaning-in-biological-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146575.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">131</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">8384</span> Airplane Stability during Climb/Descend Phase Using a Flight Dynamics Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Niloufar%20Ghoreishi">Niloufar Ghoreishi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Nekouzadeh"> Ali Nekouzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The stability of the flight during maneuvering and in response to probable perturbations is one of the most essential features of an aircraft that should be analyzed and designed for.

These sources of energy are converted into electrical energy and delivered to end-users through the utility system. As a result of the widespread use of power electronics-based grid-interfacing technologies to accommodate renewable sources of energy, the prevalence of converters has expanded as well. As a result, the power system's rotating inertia is decreasing, endangering the utility grid's stability. The use of Virtual Synchronous Machine (VSM) technology has been proposed to overcome the grid stability problem due to low rotating inertia. The grid-connected inverter used in VSM can be controlled to emulate inertia, which replicates the external features of a synchronous generator. As a result, the rotating inertia is increased to support the power system's stability. A power angle control strategy is proposed in this paper and its model is simulated in MATLAB/Simulink to study the effects of parameter disturbances on the active power and frequency for a VSM. The system consists of a synchronous generator, which is modeled in such a way that the frequency drops to an unacceptable region during transient conditions due to a lack of inertia when VSM is not used. Then, the suggested model incorporating VSM emulates rotating inertia, injecting a controllable amount of energy into the grid during frequency transients to enhance transient stability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damping%20constant" title="damping constant">damping constant</a>, <a href="https://publications.waset.org/abstracts/search?q=inertia%E2%80%93constant" title=" inertia–constant"> inertia–constant</a>, <a href="https://publications.waset.org/abstracts/search?q=ROCOF" title=" ROCOF"> ROCOF</a>, <a href="https://publications.waset.org/abstracts/search?q=transient%20stability" title=" transient stability"> transient stability</a>, <a href="https://publications.waset.org/abstracts/search?q=distributed%20sources" title=" distributed sources"> distributed sources</a> </p> <a href="https://publications.waset.org/abstracts/141846/power-angle-control-strategy-of-virtual-synchronous-machine-a-novel-approach-to-control-virtual-synchronous-machine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141846.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">207</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">8381</span> Design of Fuzzy Logic Based Global Power System Stabilizer for Dynamic Stability Enhancement in Multi-Machine Power System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20P.%20Patidar">N.

Instead of conventional input pairs like speed deviation (∆ω) and derivative of speed deviation i.e. acceleration (∆ω ̇) or speed deviation and accelerating power deviation of each machine, in this paper, deviation of active power through the tie line colligating two areas is used as one of the inputs to the fuzzy logic controller in concurrence with the speed deviation. Fuzzy Logic has the features of simple concept, easy effectuation, and computationally efficient. The advantage of this input is that, the same signal can be fed to each of the fuzzy logic controller connected with each machine. The simulated system comprises of two fully symmetrical areas coupled together by two 230 kV lines. Each area is equipped with two superposable generators rated 20 kV/900MVA and area-1 is exporting 413 MW to area-2. The effectiveness of the proposed control scheme has been assessed by performing small signal stability assessment and transient stability assessment. The proposed control scheme has been compared with a conventional PSS. Digital simulation is used to demonstrate the performance of fuzzy logic controller. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Power%20System%20Stabilizer%20%28PSS%29" title="Power System Stabilizer (PSS)">Power System Stabilizer (PSS)</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20signal%20stability" title=" small signal stability"> small signal stability</a>, <a href="https://publications.waset.org/abstracts/search?q=inter-area%20oscillation" title=" inter-area oscillation"> inter-area oscillation</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20logic%20controller" title=" fuzzy logic controller"> fuzzy logic controller</a>, <a href="https://publications.waset.org/abstracts/search?q=membership%20function" title=" membership function"> membership function</a>, <a href="https://publications.waset.org/abstracts/search?q=rule%20base" title=" rule base"> rule base</a> </p> <a href="https://publications.waset.org/abstracts/16848/design-of-fuzzy-logic-based-global-power-system-stabilizer-for-dynamic-stability-enhancement-in-multi-machine-power-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16848.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">531</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">8380</span> Global Communication: Trends and Impact of Unbalanced Information in Nigerian Society</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Uchenna%20Patricia%20Ekwugha">Uchenna Patricia Ekwugha</a>, <a href="https://publications.waset.org/abstracts/search?q=Cornelius%20Aghadiegwu%20Ukwueze"> Cornelius Aghadiegwu Ukwueze</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Global communication has changed life at the international scene affecting on the whole social, cultural and political life of individuals in a global community.

The flow can take different patterns depending on parameters like fluid velocities, pipe diameter, pipe inclination, and fluid properties. Mainly, intermittent flow is produced by the natural propagation of short and long waves, according to the Kelvin-Helmholtz Stability Theory. To model stratified flow and the onset of intermittent flow, it is crucial to have knowledge of short and long waves behavior. The two-fluid model, frequently employed for characterizing multiphase systems, becomes ill-posed for high liquid and gas velocities and large inclination angles, for short waves can develop infinite growth rates. We are interested in focusing attention on long-wave instability, which leads to the production of roll waves that may grow and result in the transition from stratified flow to intermittent flow. In this study, global and local linear stability analyses for dynamic and kinematic stability criteria predict the regions of stability of the flow for different pipe inclinations and fluid velocities in regularized and non-regularized systems, concurrently. It was possible to distinguish when: wave growth rates are absolutely bounded (stable stratified smooth flow), waves have finite growth rates (unstable stratified wavy flow), and when the equation system becomes elliptic and hyperbolization is needed. In order to bound short wave growth rates and regularize the equation system, we incorporated some lower and higher-order terms like interfacial drag and surface tension, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=linear%20stability%20analysis" title="linear stability analysis">linear stability analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=multiphase%20flow" title=" multiphase flow"> multiphase flow</a>, <a href="https://publications.waset.org/abstracts/search?q=onset%20of%20slugging" title=" onset of slugging"> onset of slugging</a>, <a href="https://publications.waset.org/abstracts/search?q=two-fluid%20model%20regularization" title=" two-fluid model regularization"> two-fluid model regularization</a> </p> <a href="https://publications.waset.org/abstracts/113094/linear-stability-analysis-of-a-regularized-two-fluid-model-for-unstable-gas-liquid-flows-in-long-hilly-terrain-pipelines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113094.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">135</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">8377</span> Stability Bound of Ruin Probability in a Reduced Two-Dimensional Risk Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zina%20Benouaret">Zina Benouaret</a>, <a href="https://publications.waset.org/abstracts/search?q=Djamil%20Aissani"> Djamil Aissani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, we introduce the qualitative and quantitative concept of the strong stability method in the risk process modeling two lines of business of the same insurance company or an insurance and re-insurance companies that divide between them both claims and premiums with a certain proportion.

Further, this study provides a comprehensive model for evaluating and analyzing insurance companies' financial position and prospective for comparing the degree of corporate governance application provisions among Jordanian insurance companies. In order to achieve the goals of the study, a whole population that consist of (27) listed insurance companies was introduced through the variables of (board of director, audit committee, internal and external auditor, board and management ownership and block holder's identities). Statistical methods were used with alternative techniques by (SPSS); where descriptive statistical techniques such as means, standard deviations were used to describe the variables, while (F) test and ANOVA analysis of variance were used to test the hypotheses of the study. The study revealed the existence of significant effect of corporate governance variables except local companies that are not listed in ASE on financial stability within control variables especially debt ratio (leverage),where it's also showed that concentration in motor third party doesn't have significant effect on insurance companies' financial stability during study period. Moreover, the study concludes that Global financial crisis affect the investment side of insurance companies with insignificant effect on the technical side. Finally, some recommendations were presented such as enhancing the laws and regulation that help the appropriate application of corporate governance, and work on activating the transparency in the disclosures of the financial statements and focusing on supporting the technical provisions for the companies, rather than focusing only on profit side. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corporate%20governance" title="corporate governance">corporate governance</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20stability%0D%0Aand%20solvency%20margin" title=" financial stability and solvency margin"> financial stability and solvency margin</a>, <a href="https://publications.waset.org/abstracts/search?q=insurance%20companies" title=" insurance companies"> insurance companies</a>, <a href="https://publications.waset.org/abstracts/search?q=Jordan" title=" Jordan"> Jordan</a> </p> <a href="https://publications.waset.org/abstracts/21449/the-effect-of-corporate-governance-on-financial-stability-and-solvency-margin-for-insurance-companies-in-jordan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21449.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">489</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">8375</span> Stability of Hybrid Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kreangkri%20Ratchagit">Kreangkri Ratchagit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is concerned with exponential stability of switched linear systems with interval time-varying delays.
