Multi-tenancy enables SaaS providers offer a single application to multiple different tenants (i.e. organizations) simultaneously. Multi-tenancy has various advantages including effective version control, cost control and much more. However, the energy consumption at datacenter is still a challenge, in modern CPU, dynamic voltage/frequency scaling is used as a standard to achieve energy efficiency in processors. However, an idle server utilizes up to 70% of its peak energy requirement to run system software and maintain essential hardware devices. In this paper, we propose an energy-aware application component migration method that computes the load of the datacenter servers by considering the number of components attached to the servers, count of tenant users accessing the application components; components strike rate and various other vital factors in choosing components to migrate. When all components of the underutilized servers are migrated the server is powered off to conserve energy. We evaluate our proposed algorithm using discrete event simulation. Our evaluation and discussion exhibits the usefulness of the proposed solution by reducing the number of server up and reducing energy consumption at datacenter.","PeriodicalId":302640,"journal":{"name":"2013 15th International Conference on Advanced Computing Technologies (ICACT)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114914361","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}

Now a day's electrical power system network has huge and complex infrastructure facility and the reliability assessment of EHVAC Substation is a critical issue for continuity of the power supply to the customer. In this paper minimal cut set method is implemented and illustrated to a practical EHVAC Substation arrangement and to assess the reliability indices for sub-station. The indices are then compared with simulation method. EHVAC Substation reliability plays a significant role in judgment on the whole system reliability. The paper utilizes a tactic for modeling, analyzing, and identifying the right configurations for substations base on diverse criteria, such as reliability requirements, load flow, cost of interruption and initial funds to run and preservation. To assess the sub-station reliability using minimal cut set method and Monte Carlo simulation approach and are compared for both theoretical and practical case. Paper presents the calculation of the most commonly used practical substation configurations using conventional and alternative technologies. A MATLAB programme is developed for evaluating EHVAC substation indices.","PeriodicalId":302640,"journal":{"name":"2013 15th International Conference on Advanced Computing Technologies (ICACT)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129282942","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}

Rapidly growing energy and battery consumption demands of mobile phones are not accomplished with advances in battery technology. Energy consumption is an important issue in android devices for mobile devices having advanced operating system. The lifetime of the battery is more and more important issue for users, for example if Wi-Fi or other applications are used continuously in the mobile, the battery of mobile discharges before its specified time. This paper presents a battery monitoring system which is capable of sensing and monitoring capability of battery of mobile phone, which is used to indicate the battery conditions in any numbers of standby powers. The battery capability is to monitor any number of cells utilizing a frequency-shift-keyed signal to sequentially interrogate each individual cell. This modulated tone responses are used to transmit the data back to the monitoring module. This paper introduces the background service name as Mainactivity. This service provides Power saver for automated power model construction method that uses built-in battery voltage sensors and knowledge of battery discharge behavior to monitor power consumption. To save android applications energy, it is critical to monitor the energy consumption of each application. As a solution to this, process acts as a background process and used to monitor battery power for each application and overall system. It also helps to inform users about the battery usage information and restricting the application which uses excess power.","PeriodicalId":302640,"journal":{"name":"2013 15th International Conference on Advanced Computing Technologies (ICACT)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125722066","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}

These VFTO's and VFTC's leads to generation of Electromagnetic fields in a gas insulated substations. These Electromagnetic fields due to VFTO's and VFTC's leads to greater damages on the insulation of equipments like power transformers, bushings, spacers etc. connected in the GIS system. These transient rise times are in nanoseconds range and the oscillations are in the MHz frequency range To evaluate the magnitudes at various locations, it is required to perform an accurate analysis on the wave shape and amplitudes of VFTO and VFTC. In this paper the component models of more accurate 420kV GIS station is considered for simulation and analyzed magnitudes at different points in the 420kV GIS, proposed the effective mitigation method to reduce the amplitude of the VFTC and VFTO is presented. Simulations are performed with more accurate modeling of 420kV GIS system model. Electro Magnetic Transient Programming (EMTP) is used to analyse the VFTO's and VFTC's at the different locations in the GIS system.
