The inherent susceptibility of digital content to malevolent manipulations renders it vulnerable to our skepticism. Establishment of authenticity of digital content is of utmost importance in situations where reliability on fraudulent evidence could have serious consequences. With the intent of tackling a few of the several challenges of the video forensics domain, in this paper we propose a potent DCT coefficient analysis-based forensic technique for reliable detection of re-compression and transcoding in digital videos. This scheme facilitates visually perceptible differentiation between singly-compressed and re-compressed video frames while circumventing the need for undertaking any complicated peak periodicity analysis procedures that are normally associated with traditional DCT-based studies. We also present a unique optical-flow analysis scheme, where, instead of inspecting inconsistencies caused by frame-removal in the entire optical flow sequences of a given video, we focus entirely on the brightness gradient component of this flow. The experiments in this regard substantiate the forensic capabilities of this component and proffer observations conducive to the detection and localization of frame-removal in digital videos. Subjective and quantitative experimentation on a comprehensive dataset under a wide range of experimental set-ups validate the efficacy and resilience of the proposed techniques.","PeriodicalId":256314,"journal":{"name":"2015 2nd International Conference on Recent Advances in Engineering & Computational Sciences (RAECS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130937736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A good and efficient transport is a key factor in mass production where the goods can reach the consumer from the production site or factory which may be situated many miles away. It has been studied with the objective of minimizing cost and the time to simulate different real life problems. In this paper, we study a time minimizing transportation problem in which the exact total demand of the destinations cannot be satisfied in one go. Due to some reasons, only a particular amount less than the exact total demand, can be transported first and therefore, rest of the amount has to be transported later. It gives rise to a two stage time minimizing transportation problem in which the stage-I flow is restricted. The present study proposes an iterative algorithm which concentrates on minimizing the total time of transportation of both the stages. At each iteration, a pair of times of Stage-I and Stage-II is generated with Stage-II time strictly less than the Stage-II time of the previous iteration. The pair with the minimum sum of Stage-I and Stage-II times is considered as the optimal pair and the corresponding transportation schedule is considered as the optimal solution of the problem.","PeriodicalId":256314,"journal":{"name":"2015 2nd International Conference on Recent Advances in Engineering & Computational Sciences (RAECS)","volume":"518 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116242194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent technological advances in high performance computing (HPC) have resulted in versatile performance improvements, though at the cost of increased energy consumption and resources. In this paper, we have developed an energy efficient algorithm for scheduling any directed acyclic graph (DAG) on heterogeneous cluster system to address bi-objectives issues: maintain performance and improve the total system energy consumption accounting for both computation energy (busy + idle) of processor and communication energy of network interconnect. We integrate dynamic voltage and frequency scaling (DVFS) technique to the existing non energy aware list based scheduling algorithm HEFT to generate a new energy efficient scheduling algorithm called - LDVS. From the exhaustive simulation results of different random and real task graphs, it is analyzed that LDVS maintains performance (overall makespan) and also exhibits significant improvements in processor and total energy over HEFT.","PeriodicalId":256314,"journal":{"name":"2015 2nd International Conference on Recent Advances in Engineering & Computational Sciences (RAECS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121491016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This gives rise to production of current harmonics from load side and they tend to flow towards the source through Point of Common Coupling (PCC). These current harmonics further gives rise to voltage harmonics on the source side due to which nearby consumers can be affected. Thus, it is recommended to control the current harmonics on the load side itself at PCC so that they cannot interfere with the neighbouring loads. So, to avoid power quality problems at the source, custom power technology is being adopted in which number of control techniques are used to improve power quality. In this paper, an attempt has been made for selection of various such custom power devices like Distribution Static Synchronous Compensator (DSTATCOM), Static VAR Compensator (SVC), Dynamic Voltage Restorer (DVR), Unified Power Quality Compensator (UPQC) for the improvement of power quality in manufacturing industries. Then a characteristic comparison of these devices has been done. The limits imposed by IEEE and IEC standards for power quality improvement have also been discussed.","PeriodicalId":256314,"journal":{"name":"2015 2nd International Conference on Recent Advances in Engineering & Computational Sciences (RAECS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133836880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
