Such models combine different approaches for enhanced security and respecting workflow privacy. Although modern enterprises seek conformance to workflow constraints to ensure correctness of their work, these constraints pose a threat to security, because these constraints can be good seeds for attacking privacy even in secure models. This paper introduces a comprehensive Workflow Delegation Model (WFDM) that utilizes provenance and workflow constraints to prevent malicious delegate from attacking workflow privacy as well as extending the delegation functionalities. In addition, we argue the need for exploiting workflow constraints to improve workflow security models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=workflow%20delegation%20models" title="workflow delegation models">workflow delegation models</a>, <a href="https://publications.waset.org/abstracts/search?q=secure%20workflow" title=" secure workflow"> secure workflow</a>, <a href="https://publications.waset.org/abstracts/search?q=workflow%20privacy" title=" workflow privacy"> workflow privacy</a>, <a href="https://publications.waset.org/abstracts/search?q=workflow%20provenance" title=" workflow provenance"> workflow provenance</a> </p> <a href="https://publications.waset.org/abstracts/47106/preserving-privacy-in-workflow-delegation-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47106.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">904</span> Publish/Subscribe Scientific Workflow Interoperability Framework (PS-SWIF) Architecture and Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Alqaoud">Ahmed Alqaoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes Publish/Subscribe Scientific Workflow Interoperability Framework (PS-SWIF) architecture and its components that collectively provide interoperability between heterogeneous scientific workflow systems.

However, it presents various challenges that need to be addressed in order to be efficiently utilized. The resources provisioning problem for workflow applications has been widely studied. Nevertheless, the existing works did not consider the change in workflow instances while they are being executed. This functionality has become a major requirement to deal with unusual situations and evolution. This paper presents a first step towards the resources provisioning for a dynamic workflow. In fact, we propose a provisioning algorithm which minimizes the overall workflow execution cost, while meeting a deadline constraint. Then, we extend it to support the dynamic adding of tasks. Experimental results show that our proposed heuristic demonstrates a significant reduction in resources cost by using a consolidation process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title="cloud computing">cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=resources%20provisioning" title=" resources provisioning"> resources provisioning</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20workflow" title=" dynamic workflow"> dynamic workflow</a>, <a href="https://publications.waset.org/abstracts/search?q=workflow%20applications" title=" workflow applications"> workflow applications</a> </p> <a href="https://publications.waset.org/abstracts/19467/towards-a-resources-provisioning-for-dynamic-workflows-in-the-cloud" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19467.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">295</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">902</span> An Integrated Web-Based Workflow System for Design of Computational Pipelines in the Cloud</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shuen-Tai%20Wang">Shuen-Tai Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Ching%20Lin"> Yu-Ching Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With more and more workflow systems adopting cloud as their execution environment, it presents various challenges that need to be addressed in order to be utilized efficiently.

We also propose an integrated web-based workflow designer by taking advantage of the HTML5 technology and chaining together multiple tools.

In this paper, the activity executive time is divided into the service time and the waiting time, then the lead time can be extracted from the waiting time. The executive time formulas of the three basic structures in the workflow network are deduced based on the activity lead time. Taken the process of e-commerce logistics as an example, insert appropriate lead time for key activities by using Petri net, and the executive time optimization model is built to minimize the waiting time with the time-cost constraints. Then the solution program-using VC++6.0 is compiled to get the optimal solution, which reduces the waiting time of key activities in the workflow, and verifies the role of lead time in the timeliness of e-commerce logistics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electronic%20business" title="electronic business">electronic business</a>, <a href="https://publications.waset.org/abstracts/search?q=execution%20time" title=" execution time"> execution time</a>, <a href="https://publications.waset.org/abstracts/search?q=lead%20time" title=" lead time"> lead time</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization%20model" title=" optimization model"> optimization model</a>, <a href="https://publications.waset.org/abstracts/search?q=petri%20net" title=" petri net"> petri net</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20workflow%20network" title=" time workflow network"> time workflow network</a> </p> <a href="https://publications.waset.org/abstracts/137019/execution-time-optimization-of-workflow-network-with-activity-lead-time" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137019.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">176</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">898</span> Developing a Web-Based Workflow Management System in Cloud Computing Platforms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wang%20Shuen-Tai">Wang Shuen-Tai</a>, <a href="https://publications.waset.org/abstracts/search?q=Lin%20Yu-Ching"> Lin Yu-Ching</a>, <a href="https://publications.waset.org/abstracts/search?q=Chang%20Hsi-Ya"> Chang Hsi-Ya </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cloud computing is the innovative and leading information technology model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort. In this paper, we aim at the development of workflow management system for cloud computing platforms based on our previous research on the dynamic allocation of the cloud computing resources and its workflow process. We took advantage of the HTML 5 technology and developed web-based workflow interface. In order to enable the combination of many tasks running on the cloud platform in sequence, we designed a mechanism and developed an execution engine for workflow management on clouds. We also established a prediction model which was integrated with job queuing system to estimate the waiting time and cost of the individual tasks on different computing nodes, therefore helping users achieve maximum performance at lowest payment. This proposed effort has the potential to positively provide an efficient, resilience and elastic environment for cloud computing platform. This development also helps boost user productivity by promoting a flexible workflow interface that lets users design and control their tasks' flow from anywhere. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=web-based" title="web-based">web-based</a>, <a href="https://publications.waset.org/abstracts/search?q=workflow" title=" workflow"> workflow</a>, <a href="https://publications.waset.org/abstracts/search?q=HTML5" title=" HTML5"> HTML5</a>, <a href="https://publications.waset.org/abstracts/search?q=Cloud%20Computing" title=" Cloud Computing"> Cloud Computing</a>, <a href="https://publications.waset.org/abstracts/search?q=Queuing%20System" title=" Queuing System"> Queuing System</a> </p> <a href="https://publications.waset.org/abstracts/29622/developing-a-web-based-workflow-management-system-in-cloud-computing-platforms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29622.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">309</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">897</span> Four Phase Methodology for Developing Secure Software</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Gonzalez-Flores">Carlos Gonzalez-Flores</a>, <a href="https://publications.waset.org/abstracts/search?q=Ernesto%20Li%C3%B1an-Garc%C3%ADa"> Ernesto Liñan-García</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A simple and robust approach for developing secure software.

Our methodology requires first the determination and understanding of the type of security level needed for the software. The methodology proposes the use of several teams to accomplish this task. One Software Engineering Developing Team, a Compiler Team, a Specification and Requirements Testing Team, and for each of the secure software developing types: three teams of Secure Software Developing, three teams of Code Breakers, and three teams of Intrusion Analysis.

Distributed privacy preserving data mining involve two to more sites that cannot pool in their data to a third party due to the violation of law regarding the individual.

Hospitals workflow is a complex and complicated process and poor patient flow can put both patients and a hospital’s reputation at risk, and can threaten the facility’s financial sustainability. Healthcare leaders are under increased pressure to reduce costs while maintaining or increasing patient care standards. In this paper, a framework is proposed to help improving patient experience, staff satisfaction, and operational efficiency across hospitals by using knowledge management based visualisation concepts.

However, the importance of seismic trace data will be undermined unless the geo-spatial component of the data is understood. Deriving a proposed well to be drilled from data that has positional ambiguity will jeopardize business decision and millions of dollars’ investment that every oil and gas company would like to avoid. Spatial integrity QC workflow has been introduced in PETRONAS to ensure positional errors within the seismic data are recognized throughout the exploration’s lifecycle from acquisition, processing, and seismic interpretation. This includes, amongst other tests, quantifying that the data is referenced to the appropriate coordinate reference system, survey configuration validation, and geometry loading verification. The direct outcome of the workflow implementation helps improve reliability and integrity of sub-surface geological model produced by geoscientist and provide important input to potential hazard assessment where positional accuracy is crucial.

The image is divided into two different components, for which encryption and feature extraction are executed separately. As a result, cloud server can extract features from an encrypted image directly and compare them with the features of the queried images, so that the user can thus obtain the image. Different from other methods, the proposed method has no special requirements to encryption algorithms.

KNIME improved workflow is an open-source data-analytics platform that integrates a number of open-source metabolomics tools such as CFMID and MetFrag to provide standard data visualisations, predict candidate metabolites, assess them against experimental data, and produce reports on identified metabolites. The use of this workflow is demonstrated by employing three types of liver microsomes (human, rat, and Guinea pig) to study the in vitro metabolism of the two drugs (AMI and VER). This workflow is used to create and treat UPLC-MS (Orbitrap) data. The formulas and structures of these drugs' metabolites can be assigned automatically. The key metabolic routes for amitriptyline are hydroxylation, N-dealkylation, N-oxidation, and conjugation, while N-demethylation, O-demethylation and N-dealkylation, and conjugation are the primary metabolic routes for verapamil. The identified metabolites are compatible to the published, clarifying the solidity of the workflow technique and the usage of computational tools like KNIME in supporting the integration and interoperability of emerging novel software packages in the metabolomics area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=KNIME" title="KNIME">KNIME</a>, <a href="https://publications.waset.org/abstracts/search?q=CFMID" title=" CFMID"> CFMID</a>, <a href="https://publications.waset.org/abstracts/search?q=MetFrag" title=" MetFrag"> MetFrag</a>, <a href="https://publications.waset.org/abstracts/search?q=Data%20Analysis" title=" Data Analysis"> Data Analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Metabolomics" title=" Metabolomics"> Metabolomics</a> </p> <a href="https://publications.waset.org/abstracts/147907/employing-a-knime-based-and-open-source-tools-to-identify-ami-and-ver-metabolites-from-uplc-ms-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147907.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">888</span> A Secure Proxy Signature Scheme with Fault Tolerance Based on RSA System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20El-Kamchouchi">H.

This difficulty is related to the rapid evaluation of Telecommunication and multimedia systems accompanied by a rapid increase of user requirements in terms of latency, execution time, consumption, energy, etc. Having an optimal scheduling on multi-cores DSP (Digital signal Processors) platforms is a challenging task. In this context, we present a novel technic and algorithm in order to find a valid schedule that optimizes the key performance metrics particularly the Latency. Our contribution is based on Satisfiability Modulo Theories (SMT) solving technologies which is strongly driven by the industrial applications and needs. This paper, describe a scheduling module integrated in our proposed Workflow which is advised to be a successful approach for programming the applications based on NoC-DSP platforms. This workflow transform automatically a Simulink model to a synchronous dataflow (SDF) model. The automatic transformation followed by SMT solver scheduling aim to minimize the final latency and other software/hardware metrics in terms of an optimal schedule. Also, finding the optimal numbers of cores to be used. In fact, our proposed workflow taking as entry point a Simulink file (.mdl or .slx) derived from embedded Matlab functions. We use an approach which is based on the synchronous and hierarchical behavior of both Simulink and SDF. Whence, results of running the scheduler which exist in the Workflow mentioned above using our proposed SMT solver algorithm refinements produce the best possible scheduling in terms of latency and numbers of cores. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi-cores%20DSP" title="multi-cores DSP">multi-cores DSP</a>, <a href="https://publications.waset.org/abstracts/search?q=scheduling" title=" scheduling"> scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=SMT%20solver" title=" SMT solver"> SMT solver</a>, <a href="https://publications.waset.org/abstracts/search?q=workflow" title=" workflow"> workflow</a> </p> <a href="https://publications.waset.org/abstracts/67632/using-the-smt-solver-to-minimize-the-latency-and-to-optimize-the-number-of-cores-in-an-noc-dsp-architectures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67632.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">286</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">885</span> Proposal of Optimality Evaluation for Quantum Secure Communication Protocols by Taking the Average of the Main Protocol Parameters: Efficiency, Security and Practicality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Georgi%20Bebrov">Georgi Bebrov</a>, <a href="https://publications.waset.org/abstracts/search?q=Rozalina%20Dimova"> Rozalina Dimova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the field of quantum secure communication, there is no evaluation that characterizes quantum secure communication (QSC) protocols in a complete, general manner. The current paper addresses the problem concerning the lack of such an evaluation for QSC protocols by introducing an optimality evaluation, which is expressed as the average over the three main parameters of QSC protocols: efficiency, security, and practicality. For the efficiency evaluation, the common expression of this parameter is used, which incorporates all the classical and quantum resources (bits and qubits) utilized for transferring a certain amount of information (bits) in a secure manner. By using criteria approach whether or not certain criteria are met, an expression for the practicality evaluation is presented, which accounts for the complexity of the QSC practical realization. Based on the error rates that the common quantum attacks (Measurement and resend, Intercept and resend, probe attack, and entanglement swapping attack) induce, the security evaluation for a QSC protocol is proposed as the minimum function taken over the error rates of the mentioned quantum attacks. For the sake of clarity, an example is presented in order to show how the optimality is calculated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quantum%20cryptography" title="quantum cryptography">quantum cryptography</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20secure%20communcation" title=" quantum secure communcation"> quantum secure communcation</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20secure%20direct%20communcation%20security" title=" quantum secure direct communcation security"> quantum secure direct communcation security</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20secure%20direct%20communcation%20efficiency" title=" quantum secure direct communcation efficiency"> quantum secure direct communcation efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20secure%20direct%20communcation%20practicality" title=" quantum secure direct communcation practicality"> quantum secure direct communcation practicality</a> </p> <a href="https://publications.waset.org/abstracts/104501/proposal-of-optimality-evaluation-for-quantum-secure-communication-protocols-by-taking-the-average-of-the-main-protocol-parameters-efficiency-security-and-practicality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104501.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">184</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">884</span> Secure Cryptographic Operations on SIM Card for Mobile Financial Services</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kerem%20Ok">Kerem Ok</a>, <a href="https://publications.waset.org/abstracts/search?q=Serafettin%20Senturk"> Serafettin Senturk</a>, <a href="https://publications.waset.org/abstracts/search?q=Serdar%20Aktas"> Serdar Aktas</a>, <a href="https://publications.waset.org/abstracts/search?q=Cem%20Cevikbas"> Cem Cevikbas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mobile technology is very popular nowadays and it provides a digital world where users can experience many value-added services. Service Providers are also eager to offer diverse value-added services to users such as digital identity, mobile financial services and so on. In this context, the security of data storage in smartphones and the security of communication between the smartphone and service provider are critical for the success of these services. In order to provide the required security functions, the SIM card is one acceptable alternative. Since SIM cards include a Secure Element, they are able to store sensitive data, create cryptographically secure keys, encrypt and decrypt data. In this paper, we design and implement a SIM and a smartphone framework that uses a SIM card for secure key generation, key storage, data encryption, data decryption and digital signing for mobile financial services. Our frameworks show that the SIM card can be used as a controlled Secure Element to provide required security functions for popular e-services such as mobile financial services. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SIM%20card" title="SIM card">SIM card</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20financial%20services" title=" mobile financial services"> mobile financial services</a>, <a href="https://publications.waset.org/abstracts/search?q=cryptography" title=" cryptography"> cryptography</a>, <a href="https://publications.waset.org/abstracts/search?q=secure%20data%20storage" title=" secure data storage"> secure data storage</a> </p> <a href="https://publications.waset.org/abstracts/54843/secure-cryptographic-operations-on-sim-card-for-mobile-financial-services" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54843.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">312</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">883</span> A Review on Factors Influencing Implementation of Secure Software Development Practices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sri%20Lakshmi%20Kanniah">Sri Lakshmi Kanniah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Naz%E2%80%99ri%20Mahrin"> Mohd Naz’ri Mahrin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> More and more businesses and services are depending on software to run their daily operations and business services. At the same time, cyber-attacks are becoming more covert and sophisticated, posing threats to software. Vulnerabilities exist in the software due to the lack of security practices during the phases of software development. Implementation of secure software development practices can improve the resistance to attacks. Many methods, models and standards for secure software development have been developed. However, despite the efforts, they still come up against difficulties in their deployment and the processes are not institutionalized. There is a set of factors that influence the successful deployment of secure software development processes. In this study, the methodology and results from a systematic literature review of factors influencing the implementation of secure software development practices is described. A total of 44 primary studies were analysed as a result of the systematic review. As a result of the study, a list of twenty factors has been identified. Some of factors that affect implementation of secure software development practices are: Involvement of the security expert, integration between security and development team, developer’s skill and expertise, development time and communication between stakeholders. The factors were further classified into four categories which are institutional context, people and action, project content and system development process. The results obtained show that it is important to take into account organizational, technical and people issues in order to implement secure software development initiatives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=secure%20software%20development" title="secure software development">secure software development</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20development" title=" software development"> software development</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20security" title=" software security"> software security</a>, <a href="https://publications.waset.org/abstracts/search?q=systematic%20literature%20review" title=" systematic literature review"> systematic literature review</a> </p> <a href="https://publications.waset.org/abstracts/52959/a-review-on-factors-influencing-implementation-of-secure-software-development-practices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52959.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">378</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">882</span> Application of Systems Engineering Tools and Methods to Improve Healthcare Delivery Inside the Emergency Department of a Mid-Size Hospital</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Elshal">Mohamed Elshal</a>, <a href="https://publications.waset.org/abstracts/search?q=Hazim%20El-Mounayri"> Hazim El-Mounayri</a>, <a href="https://publications.waset.org/abstracts/search?q=Omar%20El-Mounayri"> Omar El-Mounayri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Emergency department (ED) is considered as a complex system of interacting entities: patients, human resources, software and hardware systems, interfaces, and other systems. This paper represents a research for implementing a detailed Systems Engineering (SE) approach in a mid-size hospital in central Indiana. This methodology will be applied by “The Initiative for Product Lifecycle Innovation (IPLI)” institution at Indiana University to study and solve the crowding problem with the aim of increasing throughput of patients and enhance their treatment experience; therefore, the nature of crowding problem needs to be investigated with all other problems that leads to it. The presented SE methods are workflow analysis and systems modeling where SE tools such as Microsoft Visio are used to construct a group of system-level diagrams that demonstrate: patient’s workflow, documentation and communication flow, data systems, human resources workflow and requirements, leadership involved, and integration between ER different systems. Finally, the ultimate goal will be managing the process through implementation of an executable model using commercialized software tools, which will identify bottlenecks, improve documentation flow, and help make the process faster. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=systems%20modeling" title="systems modeling">systems modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=ED%20operation" title=" ED operation"> ED operation</a>, <a href="https://publications.waset.org/abstracts/search?q=workflow%20modeling" title=" workflow modeling"> workflow modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=systems%20analysis" title=" systems analysis"> systems analysis</a> </p> <a href="https://publications.waset.org/abstracts/55693/application-of-systems-engineering-tools-and-methods-to-improve-healthcare-delivery-inside-the-emergency-department-of-a-mid-size-hospital" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55693.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">181</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">881</span> An Efficient Proxy Signature Scheme Over a Secure Communications Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20El-Kamchouchi">H.

With a continual increase in computational tools to assess these impacts, the need for scalability and reproducibility became an essential component of computational analysis and experimental research. Here it introduce a bioinformatics pipeline that combines several structural analysis tools in a simplified workflow, by optimizing the present computational hardware and software to automatically ease the flow of data transformations. Utilizing preestablished software tools, it was possible to develop a pipeline with a set of pre-defined functions that will automate mutation introduction into the HIV-1 Integrase protein structure, calculate the gain and loss of polar interactions and calculate the change in energy of protein fold. Additionally, an automated molecular dynamics analysis was implemented which reduces the constant need for user input and output management. The resulting pipeline, Automated Mutation Introduction and Analysis (AMIA) is an open source set of scripts designed to introduce and analyse the effects of mutations on the static protein structure as well as the results of the multi-conformational states from molecular dynamic simulations. The workflow allows the user to visualize all outputs in a user friendly manner thereby successfully enabling the prioritization of variant systems for experimental validation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automated%20workflow" title="automated workflow">automated workflow</a>, <a href="https://publications.waset.org/abstracts/search?q=variant%20prioritization" title=" variant prioritization"> variant prioritization</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20resistance" title=" drug resistance"> drug resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=HIV%20Integrase" title=" HIV Integrase"> HIV Integrase</a> </p> <a href="https://publications.waset.org/abstracts/178777/the-development-of-an-automated-computational-workflow-to-prioritize-potential-resistance-variants-in-hiv-integrase-subtype-c" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178777.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">77</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">879</span> A Software Engineering Methodology for Developing Secure Obfuscated Software</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Gonzalez">Carlos Gonzalez</a>, <a href="https://publications.waset.org/abstracts/search?q=Ernesto%20Linan"> Ernesto Linan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We propose a methodology to conciliate two apparently contradictory processes in the development of secure obfuscated software and good software engineered software. Our methodology consists first in the system designers defining the type of security level required for the software. There are four types of attackers: casual attackers, hackers, institution attack, and government attack. Depending on the level of threat, the methodology we propose uses five or six teams to accomplish this task. One Software Engineer Team and one or two software Obfuscation Teams, and Compiler Team, these four teams will develop and compile the secure obfuscated software, a Code Breakers Team will test the results of the previous teams to see if the software is not broken at the required security level, and an Intrusion Analysis Team will analyze the results of the Code Breakers Team and propose solutions to the development teams to prevent the detected intrusions.

Although this discipline is developing for many years, there is still necessity of creating new opportunities to meet the ever-increasing users’ needs. Because one of these needs is related to the conversion of business process models from one standard to another, the authors have developed a converter between BPMN and EPC standards using workflow patterns as intermediate tool. Nowadays there are too many systems for business process modeling. The variety of output formats is almost the same as the systems themselves. This diversity additionally hampers the conversion of the models.
