Hence, power load forecasting is the parameter which facilitates understanding and analyzing all these aspects. In this paper, power load forecasting is solved under MATLAB environment by constructing a neural network for the power load to find an accurate simulated solution with the minimum error. A developed algorithm to achieve load forecasting application with faster technique is the aim for this paper. The algorithm is used to enable MATLAB power application to be implemented by multi machines in the Grid computing system, and to accomplish it within much less time, cost and with high accuracy and quality. Grid Computing, the modern computational distributing technology, has been used to enhance the performance of power applications by utilizing idle and desired Grid contributor(s) by sharing computational power resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DeskGrid" title="DeskGrid">DeskGrid</a>, <a href="https://publications.waset.org/abstracts/search?q=Grid%20Server" title=" Grid Server"> Grid Server</a>, <a href="https://publications.waset.org/abstracts/search?q=idle%20contributor%28s%29" title=" idle contributor(s)"> idle contributor(s)</a>, <a href="https://publications.waset.org/abstracts/search?q=grid%20computing" title=" grid computing"> grid computing</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20forecasting" title=" load forecasting"> load forecasting</a> </p> <a href="https://publications.waset.org/abstracts/7716/utilizing-grid-computing-to-enhance-power-systems-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7716.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">475</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">1279</span> On Four Models of a Three Server Queue with Optional Server Vacations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kailash%20C.%20Madan">Kailash C.

In which normal user can not have control over particular website or server? By using the same processing model one can have unauthorized access to particular server. In this paper, we discussed about application scenario of hacking for simple website or server consist of unauthorized way to access the server database. This application emerges to autonomously take direct access of simple website or server and retrieve all essential information maintain by administrator. In this system, IP address of server given as input to retrieve user-id and password of server. This leads to breaking administrative security of server and acquires the control of server database. Whereas virus helps to escape from server security by crashing the whole server. Objective: To control malicious attack and preventing all government website, and also find out illegal work to do hackers activity. Results: After implementing different hacking as well as non-hacking techniques, this system hacks simple web sites with normal security credentials. It provides access to server database and allow attacker to perform database operations from client machine. Above Figure shows the experimental result of this application upon different servers and provides satisfactory results as required. Conclusion: In this paper, we have presented a to view to hack the server which include some hacking as well as non-hacking methods. These algorithms and methods provide efficient way to hack server database. By breaking the network security allow to introduce new and better security framework. The terms “Hacking” not only consider for its illegal activities but also it should be use for strengthen our global network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hacking" title="Hacking">Hacking</a>, <a href="https://publications.waset.org/abstracts/search?q=Vulnerabilities" title=" Vulnerabilities"> Vulnerabilities</a>, <a href="https://publications.waset.org/abstracts/search?q=Dummy%20request" title=" Dummy request"> Dummy request</a>, <a href="https://publications.waset.org/abstracts/search?q=Virus" title=" Virus"> Virus</a>, <a href="https://publications.waset.org/abstracts/search?q=Server%20monitoring" title=" Server monitoring"> Server monitoring</a> </p> <a href="https://publications.waset.org/abstracts/36777/client-hacked-server" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36777.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">251</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">1277</span> Computer Server Virtualization </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pradeep%20M.%20C.%20Chand">Pradeep M.

Proposed micro grid has an AC-bus and DC-bus, interconnected together with a tie line DC-AC converter. In grid-connected mode AC bus of microgrid is synchronized with utility grid. Synchronization with utility grid requires grid and AC bus to have synchronism in frequency, phase sequence and voltage. Power flow requires phase difference between grid and AC bus. Control System is required to effectively regulate power flow between the grid and AC bus. The grid synchronizing control system is composed of frequency and phase control for regulated power flow and voltage control system for reduction of reactive power flow. The control system involves automatic active power flow control. It takes the feedback of DC link Capacitor and changes the power angle accordingly. Control system incorporating voltage, phase and power control was developed for grid-tie inverter.

In each prioritized, limited server, different service ratio is assigned to each class request, and the number of requests to be processed is limited to less than a certain number. Routing strategies of such prioritized, limited multi-server PS systems that take into account the capacity of each server are also presented, and a performance evaluation procedure for these strategies is discussed. Practical performance measures of these strategies, such as loss probability, mean waiting time, and mean sojourn time, are evaluated via simulation. In the PS server, at the arrival (or departure) of a request, the extension (shortening) of the remaining sojourn time of each request receiving service can be calculated by using the number of requests of each class and the priority ratio. Utilising a simulation program which executes these events and calculations, the performance of the proposed prioritized, limited multi-server PS rule can be analyzed. From the evaluation results, most suitable routing strategy for the loss or waiting system is clarified. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=processor%20sharing" title="processor sharing">processor sharing</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-server" title=" multi-server"> multi-server</a>, <a href="https://publications.waset.org/abstracts/search?q=various%20capacity" title=" various capacity"> various capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=N-priority%20classes" title=" N-priority classes"> N-priority classes</a>, <a href="https://publications.waset.org/abstracts/search?q=routing%20strategy" title=" routing strategy"> routing strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=loss%20probability" title=" loss probability"> loss probability</a>, <a href="https://publications.waset.org/abstracts/search?q=mean%20sojourn%20time" title=" mean sojourn time"> mean sojourn time</a>, <a href="https://publications.waset.org/abstracts/search?q=mean%20waiting%20time" title=" mean waiting time"> mean waiting time</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/45569/performance-evaluation-of-a-prioritized-limited-multi-server-processor-sharing-system-that-includes-servers-with-various-capacities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45569.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">331</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">1270</span> Autonomic Recovery Plan with Server Virtualization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Hameed">S.

In addition to hardware cost reduction and data center trail, the disaster recovery plan can ensure system uptime and to meet objectives of high availability, recovery time, recovery point, server provisioning, and quality of services. This autonomic solution would also support disaster management, testing, and development of the recovery site. In this research, a workflow plan is proposed for supporting disaster recovery with virtualization providing virtual monitoring, requirements engineering, solution decision making, quality testing, and disaster management. This recovery model would make disaster recovery a lot easier, faster, and less error prone. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autonomous%20intelligence" title="autonomous intelligence">autonomous intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=disaster%20recovery" title=" disaster recovery"> disaster recovery</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=server%20virtualization" title=" server virtualization"> server virtualization</a> </p> <a href="https://publications.waset.org/abstracts/129654/autonomic-recovery-plan-with-server-virtualization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129654.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">162</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1269</span> Privacy-Preserving Location Sharing System with Client/Server Architecture in Mobile Online Social Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xi%20Xiao">Xi Xiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Chunhui%20Chen"> Chunhui Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Xinyu%20Liu"> Xinyu Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Guangwu%20Hu"> Guangwu Hu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Jiang"> Yong Jiang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Location sharing is a fundamental service in mobile Online Social Networks (mOSNs), which raises significant privacy concerns in recent years. Now, most location-based service applications adopt client/server architecture. In this paper, a location sharing system, named CSLocShare, is presented to provide flexible privacy-preserving location sharing with client/server architecture in mOSNs. CSLocShare enables location sharing between both trusted social friends and untrusted strangers without the third-party server. In CSLocShare, Location-Storing Social Network Server (LSSNS) provides location-based services but do not know the users’ real locations. The thorough analysis indicates that the users’ location privacy is protected. Meanwhile, the storage and the communication cost are saved. CSLocShare is more suitable and effective in reality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mobile%20online%20social%20networks" title="mobile online social networks">mobile online social networks</a>, <a href="https://publications.waset.org/abstracts/search?q=client%2Fserver%20architecture" title=" client/server architecture"> client/server architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=location%20sharing" title=" location sharing"> location sharing</a>, <a href="https://publications.waset.org/abstracts/search?q=privacy-preserving" title=" privacy-preserving"> privacy-preserving</a> </p> <a href="https://publications.waset.org/abstracts/57662/privacy-preserving-location-sharing-system-with-clientserver-architecture-in-mobile-online-social-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57662.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">330</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">1268</span> PSS®E Based Modelling, Simulation and Synchronous Interconnection of Eastern Grid and North-Eastern Regional Grid of India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Toushik%20Maiti">Toushik Maiti</a>, <a href="https://publications.waset.org/abstracts/search?q=Saibal%20Chatterjee"> Saibal Chatterjee</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamaljyoti%20Gogoi"> Kamaljyoti Gogoi</a>, <a href="https://publications.waset.org/abstracts/search?q=Arijit%20Basuray"> Arijit Basuray</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Eastern Regional(ER) Grid and North Eastern Regional (NER) Grid are two major grids of Eastern Part of India.

In this work, we consider a $M/G/1$ retrial queue with an unreliable server with random vacations and two types of primary customers, persistent and impatient. This model involves the unreliability of the server, which can be subject to physical breakdowns and takes into account the correctives maintenances for restoring the service when a failure occurs. On the other hand, we consider random vacations, which can model the preventives maintenances for improving system performances and preventing breakdowns. We give the necessary and sufficient stability condition of the system. Then, we obtain the joint probability distribution of the server state and the number of customers in orbit and derive the more useful performance measures analytically. Moreover, we also analyze the busy period of the system. Finally, we derive the stability condition and the generating function of the stationary distribution of the number of customers in the system when there is no vacations and impatient customers, and when there is no vacations, server failures and impatient customers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=modeling" title="modeling">modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=retrial%20queue" title=" retrial queue"> retrial queue</a>, <a href="https://publications.waset.org/abstracts/search?q=unreliable%20server" title=" unreliable server"> unreliable server</a>, <a href="https://publications.waset.org/abstracts/search?q=vacation" title=" vacation"> vacation</a>, <a href="https://publications.waset.org/abstracts/search?q=stochastic%20analysis" title=" stochastic analysis"> stochastic analysis</a> </p> <a href="https://publications.waset.org/abstracts/109241/analysis-of-the-unreliable-mg1-retrial-queue-with-impatient-customers-and-server-vacation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109241.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">185</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">1266</span> Load Balancing Algorithms for SIP Server Clusters in Cloud Computing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tanmay%20Raj">Tanmay Raj</a>, <a href="https://publications.waset.org/abstracts/search?q=Vedika%20Gupta"> Vedika Gupta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For its groundbreaking and substantial power, cloud computing is today’s most popular breakthrough. It is a sort of Internet-based computing that allows users to request and receive numerous services in a cost-effective manner. Virtualization, grid computing, and utility computing are the most widely employed emerging technologies in cloud computing, making it the most powerful. However, cloud computing still has a number of key challenges, such as security, load balancing, and non-critical failure adaption, to name a few. The massive growth of cloud computing will put an undue strain on servers. As a result, network performance will deteriorate. A good load balancing adjustment can make cloud computing more productive and in- crease client fulfillment execution. Load balancing is an important part of cloud computing because it prevents certain nodes from being overwhelmed while others are idle or have little work to perform. Response time, cost, throughput, performance, and resource usage are all parameters that may be improved using load balancing. <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=load%20balancing" title=" load balancing"> load balancing</a>, <a href="https://publications.waset.org/abstracts/search?q=computing" title=" computing"> computing</a>, <a href="https://publications.waset.org/abstracts/search?q=SIP%20server%20clusters" title=" SIP server clusters"> SIP server clusters</a> </p> <a href="https://publications.waset.org/abstracts/150361/load-balancing-algorithms-for-sip-server-clusters-in-cloud-computing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150361.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">123</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">1265</span> Overview of Smart Grid Applications in Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onur%20Elma">Onur Elma</a>, <a href="https://publications.waset.org/abstracts/search?q=Giray%20E.%20K%C4%B1ral"> Giray E.

The use of new large scale coal fired power plants will also make this situation worst. Therefore, the greatest challenge in our society is to explore new ways to power off grid remote areas with renewable energy sources. It is time for a sustainable energy policy which puts consumers, the environment, human health, and peace first. The renewable energy is one of the biggest growing sectors of the energy industry. Therefore, the large scale use of micro grid is thus described here with modeling, simulation, planning and operating of the micro grid. The goal of this research paper is to go into detail of a library of major components of micro grid. The introduction will go through the detail view of micro grid definition. Then, the simulation of Micro Grid in MATLAB/ Simulink including the Photo Voltaic Cell will be described with the detailed modeling.

Often, due to high load and over time, various hardware faults occur in servers that translate to errors, resulting to malfunction or even server breakdown. CPU, RAM and hard drive (HDD) are the hardware parts that concern server administrators the most regarding errors. In this work, selected RAM, HDD and CPU errors, that have been observed or can be simulated in kernel ring buffer log files from two groups of Linux servers, are investigated. Moreover, a severity characterization is given for each error type. Better understanding of such errors can lead to more efficient analysis of kernel logs that are usually exploited for fault diagnosis and prediction. In addition, this work summarizes ways of simulating hardware errors in RAM and HDD, in order to test the error detection and correction mechanisms of a Linux server. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hardware%20errors" title="hardware errors">hardware errors</a>, <a href="https://publications.waset.org/abstracts/search?q=Kernel%20logs" title=" Kernel logs"> Kernel logs</a>, <a href="https://publications.waset.org/abstracts/search?q=Linux%20servers" title=" Linux servers"> Linux servers</a>, <a href="https://publications.waset.org/abstracts/search?q=RAM" title=" RAM"> RAM</a>, <a href="https://publications.waset.org/abstracts/search?q=hard%20disk" title=" hard disk"> hard disk</a>, <a href="https://publications.waset.org/abstracts/search?q=CPU" title=" CPU"> CPU</a> </p> <a href="https://publications.waset.org/abstracts/140496/hardware-error-analysis-and-severity-characterization-in-linux-based-server-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140496.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">154</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">1261</span> An Internet of Things Based Home Automation Based on Raspberry Pi and Node JS Server</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Khattab">Ahmed Khattab</a>, <a href="https://publications.waset.org/abstracts/search?q=Bassem%20Shetta"> Bassem Shetta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today, there are many branches of technology, one of them is the internet of things.

The CC consists of three servers: one database mail server, one redundant and one for sharing with the client computers in the CC (called as a local server). Observing the different possibilities of the functioning of the CC, the analysis has been done to evaluate the various popular measures of reliability such as availability, reliability, mean time to failure (MTTF), profit analysis due to the operation of the system. The system can ultimately fail due to the failure of router, redundant server before repairing the mail server and switch failure. The system can also partially fail when a local server fails. The failed devices have restored according to Least Recently Used (LRU) techniques. The system can also fail entirely due to a cooling failure of the server, electricity failure or some natural calamity like earthquake, fire tsunami, etc. All the failure rates are assumed to be constant and follow exponential time distribution, while the repair follows two types of distributions: i.e. general and Gumbel-Hougaard family copula distribution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reliability" title="reliability">reliability</a>, <a href="https://publications.waset.org/abstracts/search?q=availability%20Gumbel-Hougaard%20family%20copula" title=" availability Gumbel-Hougaard family copula"> availability Gumbel-Hougaard family copula</a>, <a href="https://publications.waset.org/abstracts/search?q=MTTF" title=" MTTF"> MTTF</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20data%20centre" title=" internet data centre"> internet data centre</a> </p> <a href="https://publications.waset.org/abstracts/17889/reliability-analysis-of-computer-centre-at-yobe-state-university-using-lru-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17889.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">530</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">1259</span> Presenting Internals of Networks Using Bare Machine Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joel%20Weymouth">Joel Weymouth</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramesh%20K.%20Karne"> Ramesh K.

It is used in programming application ns to run directly on a device. It is software that runs directly against the hardware using CPU, Memory, and I/O. The software application runs without an Operating System and resident mass storage. An important part of the BMC paradigm is the Bare Machine Internet. It utilizes an Application Development model software that interfaces directly with the hardware on a network server and file server. Because it is “bare,” it is a powerful teaching and research tool that can readily display the internals of the network protocols, software, and hardware of the applications running on the Bare Server. It was also demonstrated that the bare server was accessible by laptop and by smartphone/android. The purpose was to show the further practicality of Bare Internet in Computer Engineering and Computer Science Education and Research. It was also to show that an undergraduate student could take advantage of a bare server with any device and any browser at any release version connected to the internet. This paper presents the Bare Web Server as an educational tool. We will discuss possible applications of this paradigm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bare%20machine%20computing" title="bare machine computing">bare machine computing</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20research" title=" online research"> online research</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20technology" title=" network technology"> network technology</a>, <a href="https://publications.waset.org/abstracts/search?q=visualizing%20network%20internals" title=" visualizing network internals"> visualizing network internals</a> </p> <a href="https://publications.waset.org/abstracts/142622/presenting-internals-of-networks-using-bare-machine-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142622.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">172</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">1258</span> Searching for Forensic Evidence in a Compromised Virtual Web Server against SQL Injection Attacks and PHP Web Shell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gigih%20Supriyatno">Gigih Supriyatno</a> </p> <p class="card-text"><strong>Abstract:</strong></p> SQL injection is one of the most common types of attacks and has a very critical impact on web servers. In the worst case, an attacker can perform post-exploitation after a successful SQL injection attack. In the case of forensics web servers, web server analysis is closely related to log file analysis. But sometimes large file sizes and different log types make it difficult for investigators to look for traces of attackers on the server. The purpose of this paper is to help investigator take appropriate steps to investigate when the web server gets attacked. We use attack scenarios using SQL injection attacks including PHP backdoor injection as post-exploitation. We perform post-mortem analysis of web server logs based on Hypertext Transfer Protocol (HTTP) POST and HTTP GET method approaches that are characteristic of SQL injection attacks. In addition, we also propose structured analysis method between the web server application log file, database application, and other additional logs that exist on the webserver. This method makes the investigator more structured to analyze the log file so as to produce evidence of attack with acceptable time. There is also the possibility that other attack techniques can be detected with this method. On the other side, it can help web administrators to prepare their systems for the forensic readiness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=web%20forensic" title="web forensic">web forensic</a>, <a href="https://publications.waset.org/abstracts/search?q=SQL%20injection" title=" SQL injection"> SQL injection</a>, <a href="https://publications.waset.org/abstracts/search?q=investigation" title=" investigation"> investigation</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20shell" title=" web shell"> web shell</a> </p> <a href="https://publications.waset.org/abstracts/95122/searching-for-forensic-evidence-in-a-compromised-virtual-web-server-against-sql-injection-attacks-and-php-web-shell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95122.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">148</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">1257</span> Design of Single Phase Smart Energy Meter and Grid Tied Inverter for Smart Grid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamza%20Arif">Hamza Arif</a>, <a href="https://publications.waset.org/abstracts/search?q=Haroon%20Javaid"> Haroon Javaid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Based on hybrid energy concept of smart grid to synchronize and monitor power being generated at the user end.

However, the human eye will feel uncomfortable and it will occur diplopia if horizontal parallax is larger than eye separation. Therefore, we need to do parallax refining before conducting stereoscopic observation. Although some scholars have been devoted to online remote sensing refining, the main work of image refining is completed on the server side. There will be a significant delay when multiple users access the server at the same time. The emergence of HTML5 technology in recent years makes it possible to develop rich browser web application. Authors complete the image parallax refining on the browser side based on HTML5, while server side only need to transfer image data and parallax file to browser side according to the browser’s request. In this way, we can greatly reduce the server CPU load and allow a large number of users to access server in parallel and respond the user’s request quickly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20remote%20sensing%20images" title="3D remote sensing images">3D remote sensing images</a>, <a href="https://publications.waset.org/abstracts/search?q=parallax" title=" parallax"> parallax</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20refining" title=" online refining"> online refining</a>, <a href="https://publications.waset.org/abstracts/search?q=rich%20browser%20web%20application" title=" rich browser web application"> rich browser web application</a>, <a href="https://publications.waset.org/abstracts/search?q=HTML5" title=" HTML5"> HTML5</a> </p> <a href="https://publications.waset.org/abstracts/19927/3d-remote-sensing-images-parallax-refining-based-on-html5" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19927.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">461</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">1255</span> Design and Implementation of Grid-Connected Photovoltaic Inverter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20H.%20Lee">B.

Since the Grid environments facilitate distributed calculations, job scheduling appears in the form of a critical problem for the management of Grid sources that influences severely on the efficiency for the whole Grid environment. Due to the existence of some specifications such as sources dynamicity and conditions of the network in Grid, some algorithm should be presented to be adjustable and scalable with increasing the network growth. For this purpose, in this paper a job scheduling algorithm has been presented on the basis of learning automata in computational Grid which the performance of its results were compared with FPSO algorithm (Fuzzy Particle Swarm Optimization algorithm) and GJS algorithm (Grid Job Scheduling algorithm). The obtained numerical results indicated the superiority of suggested algorithm in comparison with FPSO and GJS. In addition, the obtained results classified FPSO and GJS in the second and third position respectively after the mentioned algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20grid" title="computational grid">computational grid</a>, <a href="https://publications.waset.org/abstracts/search?q=job%20scheduling" title=" job scheduling"> job scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20automata" title=" learning automata"> learning automata</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20scheduling" title=" dynamic scheduling"> dynamic scheduling</a> </p> <a href="https://publications.waset.org/abstracts/40508/presenting-a-job-scheduling-algorithm-based-on-learning-automata-in-computational-grid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40508.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">343</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">1253</span> Behaviours of Energy Spectrum at Low Reynolds Numbers in Grid Turbulence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md%20Kamruzzaman">Md Kamruzzaman</a>, <a href="https://publications.waset.org/abstracts/search?q=Lyazid%20Djenidi"> Lyazid Djenidi</a>, <a href="https://publications.waset.org/abstracts/search?q=R.%20A.%20Antonia"> R.

In the present case study, the dielectric liquid represents working fluid and it is in contact with server inside capsule. The capsule includes electronic component and fluid which can be modeled as saturated porous media. This medium follow Darcy flow regime and assumed to be in balance between its components. The study focus is on role of spatial parameters on thermal behavior of convective heat transfer. Based on server known unit, which is 1U, two parameters Ly and S are changed to test their effect. Meanwhile, wide-range of modified Rayleigh number, which is 0.5 to 300, are covered to better understand thermal performance. Navier-Stokes equations are used to model physical domain. Furthermore, successive over-relaxation and time marching techniques are used to solve momentum and energy equation. From obtained correlation, the in-between distance S is more effective on Nusselt number than distance to edge Ly by approximately 14%. In addition, as S increases, the average Nusselt number of the upper unit increases sharply, whereas the lower one keeps on the same level. <p class="card-text"><strong>Keywords:</strong> <a
