This paper is extraordinarily critical in view of the high failure fee of data structures in growing nations, which desire to be decreased to minimal proper levels by means of advocated interventions. This paper centers on a review of IS development in developing international locations. The paper gives evidence of the IS successes and screw-ups in developing nations and posits a version to deal with the IS failures. The proposed model can then be utilized by means of growing nations to lessen their IS mission implementation failure fee. A contrast is drawn between IS improvement in growing international locations and evolved international locations.

NICE guidance advises that palliative care should be provided to patients with both cancer and non-cancer conditions as and when required. However, there is some way to go before this guidance is consistently and effectively implemented nationwide in conditions such as heart failure. The Ambitions for Palliative and End of Life Care: A national framework for local action in England provides a set of foundations and ambitions which outline a vision for what high-quality palliative and end-of-life care look like in England. This poster aims to critically consider how to improve access to palliative care for heart failure patients in England by analysing the foundations taken from this framework to generate specific recommendations using Soft Systems Methodology (SSM). The eight foundations analysed are: ‘Personalised care planning’, ‘Shared records’, ‘Evidence and information’, ‘Involving, supporting and caring for those important to the dying Person’, ‘Education and training’, ‘24/7 access’, ‘Co-design’ and ‘Leadership.’ A number of specific recommendations have been generated which highlight a need to close the evidence-policy gap and implement policy with sufficient evidence. These recommendations, alongside the creation of an evidence-based national strategy for palliative care and heart failure, should improve access to palliative care for heart failure patients in England. Once implemented, it will be necessary to evaluate the effect of these proposals to understand if access to palliative care for heart failure patients actually improves. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=access" title="access">access</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20systems" title=" health systems"> health systems</a>, <a href="https://publications.waset.org/abstracts/search?q=heart%20failure" title=" heart failure"> heart failure</a>, <a href="https://publications.waset.org/abstracts/search?q=palliative%20care" title=" palliative care"> palliative care</a> </p> <a href="https://publications.waset.org/abstracts/146017/improving-access-to-palliative-care-for-heart-failure-patients-in-england-using-a-health-systems-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146017.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">128</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">20307</span> Binary Decision Diagram Based Methods to Evaluate the Reliability of Systems Considering Failure Dependencies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siqi%20Qiu">Siqi Qiu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yijian%20Zheng"> Yijian Zheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Xin%20Guo%20Ming"> Xin Guo Ming</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In many reliability and risk analysis, failures of components are supposed to be independent. However, in reality, the ignorance of failure dependencies among components may render the results of reliability and risk analysis incorrect. There are two principal ways to incorporate failure dependencies in system reliability and risk analysis: implicit and explicit methods. In the implicit method, failure dependencies can be modeled by joint probabilities, correlation values or conditional probabilities. In the explicit method, certain types of dependencies can be modeled in a fault tree as mutually independent basic events for specific component failures. In this paper, explicit and implicit methods based on BDD will be proposed to evaluate the reliability of systems considering failure dependencies. The obtained results prove the equivalence of the proposed implicit and explicit methods. It is found that the consideration of failure dependencies decreases the reliability of systems. This observation is intuitive, because more components fail due to failure dependencies. The consideration of failure dependencies helps designers to reduce the dependencies between components during the design phase to make the system more reliable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reliability%20assessment" title="reliability assessment">reliability assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20assessment" title=" risk assessment"> risk assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20dependencies" title=" failure dependencies"> failure dependencies</a>, <a href="https://publications.waset.org/abstracts/search?q=binary%20decision%20diagram" title=" binary decision diagram"> binary decision diagram</a> </p> <a href="https://publications.waset.org/abstracts/67235/binary-decision-diagram-based-methods-to-evaluate-the-reliability-of-systems-considering-failure-dependencies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67235.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">474</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">20306</span> Optimizing the Public Policy Information System under the Environment of E-Government</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qian%20Zaijian">Qian Zaijian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> E-government is one of the hot issues in the current academic research of public policy and management. As the organic integration of information and communication technology (ICT) and public administration, e-government is one of the most important areas in contemporary information society. Policy information system is a basic subsystem of public policy system, its operation affects the overall effect of the policy process or even exerts a direct impact on the operation of a public policy and its success or failure. The basic principle of its operation is information collection, processing, analysis and release for a specific purpose. The function of E-government for public policy information system lies in the promotion of public access to the policy information resources, information transmission through e-participation, e-consultation in the process of policy analysis and processing of information and electronic services in policy information stored, to promote the optimization of policy information systems. However, due to many factors, the function of e-government to promote policy information system optimization has its practical limits. In the building of E-government in our country, we should take such path as adhering to the principle of freedom of information, eliminating the information divide (gap), expanding e-consultation, breaking down information silos and other major path, so as to promote the optimization of public policy information systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=China" title="China">China</a>, <a href="https://publications.waset.org/abstracts/search?q=e-consultation" title=" e-consultation"> e-consultation</a>, <a href="https://publications.waset.org/abstracts/search?q=e-democracy" title=" e-democracy"> e-democracy</a>, <a href="https://publications.waset.org/abstracts/search?q=e-government" title=" e-government"> e-government</a>, <a href="https://publications.waset.org/abstracts/search?q=e-participation" title=" e-participation"> e-participation</a>, <a href="https://publications.waset.org/abstracts/search?q=ICTs" title=" ICTs"> ICTs</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20policy%20information%20systems" title=" public policy information systems"> public policy information systems</a> </p> <a href="https://publications.waset.org/abstracts/44549/optimizing-the-public-policy-information-system-under-the-environment-of-e-government" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44549.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">867</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">20305</span> Failure Analysis and Verification Using an Integrated Method for Automotive Electric/Electronic Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lei%20Chen">Lei Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Jian%20Jiao"> Jian Jiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Tingdi%20Zhao"> Tingdi Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Failures of automotive electric/electronic systems, which are universally considered to be safety-critical and software-intensive, may cause catastrophic accidents. Analysis and verification of failures in these kinds of systems is a big challenge with increasing system complexity. Model-checking is often employed to allow formal verification by ensuring that the system model conforms to specified safety properties. The system-level effects of failures are established, and the effects on system behavior are observed through the formal verification. A hazard analysis technique, called Systems-Theoretic Process Analysis, is capable of identifying design flaws which may cause potential failure hazardous, including software and system design errors and unsafe interactions among multiple system components. This paper provides a concept on how to use model-checking integrated with Systems-Theoretic Process Analysis to perform failure analysis and verification of automotive electric/electronic systems. As a result, safety requirements are optimized, and failure propagation paths are found. Finally, an automotive electric/electronic system case study is used to verify the effectiveness and practicability of the method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=failure%20analysis%20and%20verification" title="failure analysis and verification">failure analysis and verification</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20checking" title=" model checking"> model checking</a>, <a href="https://publications.waset.org/abstracts/search?q=system-theoretic%20process%20analysis" title=" system-theoretic process analysis"> system-theoretic process analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=automotive%20electric%2Felectronic%20system" title=" automotive electric/electronic system"> automotive electric/electronic system</a> </p> <a href="https://publications.waset.org/abstracts/112321/failure-analysis-and-verification-using-an-integrated-method-for-automotive-electricelectronic-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112321.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">122</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">20304</span> The Effects of Aging on the Cost of Operating and Support: An Empirical Study Applied to Weapon Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Byungchae%20Kim">Byungchae Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiwoo%20Nam"> Jiwoo Nam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aging of weapon systems can cause the failure and degeneration of components which results in increase of operating and support costs. However, whether this aging effect is significantly strong and it influences a lot on national defense spending due to the rapid increase in operating and support (O&S) costs is questionable. To figure out this, we conduct a literature review analyzing the aging effect of US weapon systems. We also conduct an empirical research using a maintenance database of Korean weapon systems, Defense Logistics Integrated Information System (DAIIS). We run regression of various types of O&S cost on weapon system age to investigate the statistical significance of aging effect and use generalized linear model to find relations between the failure of different priced components and the age. Our major finding is although aging effect exists, its impacts on weapon system cost seem to be not too large considering several characteristics of O&S cost elements not relying on the age. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=O%26S%20cost" title="O&S cost">O&S cost</a>, <a href="https://publications.waset.org/abstracts/search?q=aging%20effect" title=" aging effect"> aging effect</a>, <a href="https://publications.waset.org/abstracts/search?q=weapon%20system" title=" weapon system"> weapon system</a>, <a href="https://publications.waset.org/abstracts/search?q=GLM" title=" GLM"> GLM</a> </p> <a href="https://publications.waset.org/abstracts/121195/the-effects-of-aging-on-the-cost-of-operating-and-support-an-empirical-study-applied-to-weapon-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121195.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">142</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">20303</span> Statistical Analysis of Failure Cases in Aerospace</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20H.%20Lv">J.

Although great effort has been put onto the development of material and system reliability, the failure cases of fatal accidents still occur nowadays. Due to the complexity of the aviation system, and the interaction among the failure components, the failure analysis of the related equipment is a little difficult. This study focuses on surveying the failure cases in aviation, which are extracted from failure analysis journals, including Engineering Failure Analysis and Case studies in Engineering Failure Analysis, in order to obtain the failure sensitive factors or failure sensitive parts. The analytical results show that, among the failure cases, fatigue failure is the largest in number of occurrence. The most failed components are the disk, blade, landing gear, bearing, and fastener. The frequently failed materials consist of steel, aluminum alloy, superalloy, and titanium alloy. Therefore, in order to assure the safety in aviation, more attention should be paid to the fatigue failures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerospace" title="aerospace">aerospace</a>, <a href="https://publications.waset.org/abstracts/search?q=disk" title=" disk"> disk</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20analysis" title=" failure analysis"> failure analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue" title=" fatigue"> fatigue</a> </p> <a href="https://publications.waset.org/abstracts/77819/statistical-analysis-of-failure-cases-in-aerospace" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77819.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">332</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">20302</span> Estimating the Life-Distribution Parameters of Weibull-Life PV Systems Utilizing Non-Parametric Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saleem%20Z.%20Ramadan">Saleem Z.

The objective is to help and make their work easier; such as for a nurse or administration staff to record the medical records of the patient, and for a patient to check their bill transparently. However, several limitations still exists on such area regarding the type of data being stored in the system, ability for data transfer, storage and protocols to support communication between medical devices and digital images. This paper reports the simulation result of integrating several systems to cope with those limitations by using the Modality Worklist and DICOM standard.

The STAR topology (to be called subsystem-1) and BUS topology (to be called subsystem-2) are taken into account, which are placed at two different locations and connected to a server through a hub. In the both topologies BUS topology and STAR topology, we have assumed n clients. The system has two types of failures i.e. partial failure and complete failure. Further, the partial failure has been categorized as minor and major partial failure. It is assumed that the minor partial failure degrades the sub-systems and the major partial failure make the subsystem break down mode. The system may completely fail due to failure of server hacking and blocking etc. The system is studied using supplementary variable technique and Laplace transform by using different types of failure and two types of repair. The various measures of reliability for example, availability of system, reliability of system, MTTF, profit function for different parametric values have been discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=star%20topology" title="star topology">star topology</a>, <a href="https://publications.waset.org/abstracts/search?q=bus%20topology" title=" bus topology"> bus topology</a>, <a href="https://publications.waset.org/abstracts/search?q=blocking" title=" blocking"> blocking</a>, <a href="https://publications.waset.org/abstracts/search?q=hacking" title=" hacking"> hacking</a>, <a href="https://publications.waset.org/abstracts/search?q=Linux%20operating%20system" title=" Linux operating system"> Linux operating system</a>, <a href="https://publications.waset.org/abstracts/search?q=Gumbel-Hougaard%20family%20copula" title=" Gumbel-Hougaard family copula"> Gumbel-Hougaard family copula</a>, <a href="https://publications.waset.org/abstracts/search?q=supplementary%20variable" title=" supplementary variable"> supplementary variable</a> </p> <a href="https://publications.waset.org/abstracts/48060/stochastic-analysis-of-linux-operating-system-through-copula-distribution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48060.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">370</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">20299</span> Failure Localization of Bipolar Integrated Circuits by Implementing Active Voltage Contrast</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yiqiang%20Ni">Yiqiang Ni</a>, <a href="https://publications.waset.org/abstracts/search?q=Xuanlong%20Chen"> Xuanlong Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Enliang%20Li"> Enliang Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Linting%20Zheng"> Linting Zheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Shizheng%20Yang"> Shizheng Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bipolar ICs are playing an important role in military applications, mainly used in logic gates, such as inverter and NAND gate. The defect of metal break located on the step is one of the main failure mechanisms of bipolar ICs, resulting in open-circuit or functional failure. In this situation, general failure localization methods like optical beam-induced resistance change (OBIRCH) and photon emission microscopy (PEM) might not be fully effective. However, active voltage contrast (AVC) can be used as a voltage probe, which may pinpoint the incorrect potential and thus locate the failure position. Two case studies will be present in this paper on how to implement AVC for failure localization, and the detailed failure mechanism will be discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bipolar%20IC" title="bipolar IC">bipolar IC</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20localization" title=" failure localization"> failure localization</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20break" title=" metal break"> metal break</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20failure" title=" open failure"> open failure</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20contrast" title=" voltage contrast"> voltage contrast</a> </p> <a href="https://publications.waset.org/abstracts/132527/failure-localization-of-bipolar-integrated-circuits-by-implementing-active-voltage-contrast" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132527.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">294</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">20298</span> Failure Analysis Using Rtds for a Power System Equipped with Thyristor-Controlled Series Capacitor in Korea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chur%20Hee%20Lee">Chur Hee Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae%20in%20%20Lee"> Jae in Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Minh%20Chau%20Diah"> Minh Chau Diah</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Su%20Yoon"> Jong Su Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung%20Wan%20Kim"> Seung Wan Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper deals with Real Time Digital Simulator (RTDS) analysis about effects of transmission lines failure in power system equipped with Thyristor Controlled Series Capacitance (TCSC) in Korea.

In this test, all systems in Korea, other than those near TCSC, were abbreviated to Thevenin equivalent. The replica was tested in the case of a line failure near the TCSC, a generator failure, and a 765-kV line failure. The effects of conventional operated STATCOM, SVC and TCSC were also analyzed.

It is assumed that the intensity function depends only on the degradation value. No assumptions are made about the distribution of the failure times. A simple step-stress test is used to shorten failure time of products and a tampered failure rate (TFR) model is proposed to describe the effect of the changing stress on the intensities. We assume that some of the products that fail during the test have a cause of failure that is only known to belong to a certain subset of all possible failures. This case is known as masking. In the presence of masking, the maximum likelihood estimates (MLEs) of the model parameters are obtained through an expectation-maximization (EM) algorithm by treating the causes of failure as missing values. The effect of incomplete information on the estimation of parameters is studied through a Monte-Carlo simulation. Finally, a real example is analyzed to illustrate the application of the proposed methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cause%20of%20failure" title="cause of failure">cause of failure</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20degradation%20path" title=" linear degradation path"> linear degradation path</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability%20function" title=" reliability function"> reliability function</a>, <a href="https://publications.waset.org/abstracts/search?q=expectation-maximization%20algorithm" title=" expectation-maximization algorithm"> expectation-maximization algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=intensity" title=" intensity"> intensity</a>, <a href="https://publications.waset.org/abstracts/search?q=masked%20data" title=" masked data"> masked data</a> </p> <a href="https://publications.waset.org/abstracts/70878/a-partially-accelerated-life-test-planning-with-competing-risks-and-linear-degradation-path-under-tampered-failure-rate-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70878.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">335</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">20296</span> Artificial Intelligence in Enterprise Information Systems: A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Danah%20S.%20Alabdulmohsin">Danah S.

By studying on a theory concept of the latest Von Solms fourth waves, information security governance basically refers to the concept of a set of methods, techniques and tools that responsible for protecting resources of a computer system to ensure service availability, confidentiality and integrity of information. However, today’s information security dilemma relates to the acceptance of employees mentality. The major causes are a lack of communication and commitment. These types of management in an organisation are labelled as immoral/amoral management which effects on information security compliance. A recovery action is taken based on ‘learn a lesson from incident events’ rather than prevention. Therefore, the paper critically analysed the Von Solms fourth waves’ theory with current human events and its correlation by studying secondary data and also from qualitative analysis among employees in public sectors. ‘Three-dimensions to failure’ of information security dilemma are explained as deny, don’t know and don’t care. These three-dimensions are the most common vulnerable behaviour owned by employees. Therefore, by avoiding the three-dimensions to failure may improve the vulnerable behaviour of employees which is often related to immoral/amoral management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=information%20security%20management%20system" title="information security management system">information security management system</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20security%20behaviour" title=" information security behaviour"> information security behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20security%20governance" title=" information security governance"> information security governance</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20security%20culture" title=" information security culture"> information security culture</a> </p> <a href="https://publications.waset.org/abstracts/73708/information-security-dilemma-employees-behaviour-on-three-dimensions-to-failure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73708.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">209</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">20294</span> Reliability and Probability Weighted Moment Estimation for Three Parameter Mukherjee-Islam Failure Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ariful%20Islam">Ariful Islam</a>, <a href="https://publications.waset.org/abstracts/search?q=Showkat%20Ahmad%20Lone"> Showkat Ahmad Lone</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Mukherjee-Islam Model is commonly used as a simple life time distribution to assess system reliability. The model exhibits a better fit for failure information and provides more appropriate information about hazard rate and other reliability measures as shown by various authors. It is possible to introduce a location parameter at a time (i.e., a time before which failure cannot occur) which makes it a more useful failure distribution than the existing ones. Even after shifting the location of the distribution, it represents a decreasing, constant and increasing failure rate. It has been shown to represent the appropriate lower tail of the distribution of random variables having fixed lower bound. This study presents the reliability computations and probability weighted moment estimation of three parameter model. A comparative analysis is carried out between three parameters finite range model and some existing bathtub shaped curve fitting models. Since probability weighted moment method is used, the results obtained can also be applied on small sample cases.

Reliability on the transformers is the utmost concern, and any failure of the transformers can lead to catastrophic losses in electric power utility. The causes of transformer failure include insulation failure by partial discharge, core and tank failure, cooling unit failure, current transformer failure, etc. For the study of power transformer defects, finite element analysis (FEA) can provide valuable information on the severity of defects. FEA provides a more accurate representation of complex geometries because they consider thermal, electrical, and environmental influences on the insulation models to obtain basic characteristics of the insulation system during normal and partial discharge conditions. The purpose of this paper is the time domain analysis of defects 3D model of high voltage power transformer using FEA to study the electric field distribution at different points on the defects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=power%20transformer" title="power transformer">power transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectric%20response" title=" dielectric response"> dielectric response</a>, <a href="https://publications.waset.org/abstracts/search?q=partial%20discharge" title=" partial discharge"> partial discharge</a>, <a href="https://publications.waset.org/abstracts/search?q=insulation" title=" insulation"> insulation</a> </p> <a href="https://publications.waset.org/abstracts/113040/improvement-of-the-3d-finite-element-analysis-of-high-voltage-power-transformer-defects-in-time-domain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113040.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">158</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">20289</span> Utilization of an Object Oriented Tool to Perform Model-Based Safety Analysis According to Extended Failure System Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Royia%20Soliman">Royia Soliman</a>, <a href="https://publications.waset.org/abstracts/search?q=Salma%20ElAnsary"> Salma ElAnsary</a>, <a href="https://publications.waset.org/abstracts/search?q=Akram%20Amin%20Abdellatif"> Akram Amin Abdellatif</a>, <a href="https://publications.waset.org/abstracts/search?q=Florian%20Holzapfel"> Florian Holzapfel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Model-Based Safety Analysis (MBSA) is an approach in which the system and safety engineers share a common system model created using a model-based development process. The model can also be extended by the failure modes of the system components. There are two famous approaches for the addition of fault behaviors to system models. The first one is to enclose the failure into the system design directly. The second approach is to develop a fault model separately from the system model, thus combining both independent models for safety analysis. This paper introduces a hybrid approach of MBSA. The approach tries to use informal abstracted models to investigate failure behaviors. The approach will combine various concepts such as directed graph traversal, event lists and Constraint Satisfaction Problems (CSP). The approach is implemented using an Object Oriented programming language. The components are abstracted to its failure logic and relationships of connected components. The implemented approach is tested on various flight control systems, including electrical and multi-domain examples. The various tests are analyzed, and a comparison to different approaches is represented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flight%20control%20systems" title="flight control systems">flight control systems</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20based%20safety%20analysis" title=" model based safety analysis"> model based safety analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20assessment%20analysis" title=" safety assessment analysis"> safety assessment analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20modelling" title=" system modelling"> system modelling</a> </p> <a href="https://publications.waset.org/abstracts/99025/utilization-of-an-object-oriented-tool-to-perform-model-based-safety-analysis-according-to-extended-failure-system-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99025.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">165</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">20288</span> Rocket Launch Simulation for a Multi-Mode Failure Prediction Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mennatallah%20M.%20Hussein">Mennatallah M.

Despite rigorous testing and quality assurance, launch failures still occur, leading to significant financial losses and jeopardizing mission objectives. Traditional failure prediction methods often lack the sophistication to account for multi-mode failure scenarios, as well as the predictive capability in complex dynamic systems. Traditional approaches also rely on expert judgment, leading to variability in risk prioritization and mitigation strategies. Hence, there is a pressing need for robust approaches that enhance launch vehicle reliability from lift-off until it reaches its parking orbit through comprehensive simulation techniques. In this study, the developed model proposes a multi-mode launch vehicle simulation framework for predicting failure scenarios when incorporating new technologies, such as new propulsion systems or advanced staging separation mechanisms in the launch system. To this end, the model combined a 6-DOF system dynamics with comprehensive data analysis to simulate multiple failure modes impacting launch performance. The simulator utilizes high-fidelity physics-based simulations to capture the complex interactions between different subsystems and environmental conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=launch%20vehicle" title="launch vehicle">launch vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20prediction" title=" failure prediction"> failure prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=propulsion%20anomalies" title=" propulsion anomalies"> propulsion anomalies</a>, <a href="https://publications.waset.org/abstracts/search?q=rocket%20launch%20simulation" title=" rocket launch simulation"> rocket launch simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=rocket%20dynamics" title=" rocket dynamics"> rocket dynamics</a> </p> <a href="https://publications.waset.org/abstracts/188466/rocket-launch-simulation-for-a-multi-mode-failure-prediction-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188466.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">34</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">20287</span> Evaluation of the Use of U-Wrap Anchorage Systems for Strengthening Concrete Members Reinforced by Fiber Reinforced-Polymer Laminate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mai%20A.%20Aljaberi">Mai A.

In order to minimize the knowledge gap about the design of U-wrap anchors, this paper reports the results of tested beams which were strengthened with carbon fiber-reinforced polymer (CFRP) sheets at their tension sides and secured with U-wrap anchors at each end of the longitudinal CFRP. The beams were tested under four-point loading until failure. The parameters examined include the compressive strength of the concrete and the number of longitudinal CFRP.

The improvement of petrochemical safety is highly requested in order to prevent re-occurrence of severe accident. This study focuses on surveying the failure cases occurred in petrochemical field, which were extracted from journals of engineering failure, including engineering failure analysis and case studies in engineering failure analysis. The relation of failure mode, failure mechanism, type of components, and type of materials was analyzed in this study. And the analytical results showed that failures occurred more frequently in vessels and piping among the petrochemical equipment. Moreover, equipment made of carbon steel and stainless steel accounts for the majority of failures compared to other materials. This may be related to the application of the equipment and the performance of the material. In addition, corrosion failures were the largest in number of occurrence in the failure of petrochemical equipment, in which stress corrosion cracking accounts for a large proportion. This may have a lot to do with the service environment of the petrochemical equipment. Therefore, it can be concluded that the corrosion prevention of petrochemical equipment is particularly important. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cases%20analysis" title="cases analysis">cases analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=failure" title=" failure"> failure</a>, <a href="https://publications.waset.org/abstracts/search?q=petrochemical%20industry" title=" petrochemical industry"> petrochemical industry</a> </p> <a href="https://publications.waset.org/abstracts/77797/failure-cases-analysis-in-petrochemical-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77797.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">308</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">20284</span> Performance Assessment of Three Unit Redundant System with Environmental and Human Failure Using Copula Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20V.%20Singh">V.

Each subsystem has different types of failure and repair rates. An important cause for failure of system is unsuitability of the environmental conditions, like overheating, weather conditions, heavy rainfall, storm etc. The environmental failure is taken into account in the proposed repairable system.
