ELC regulated synchronous generators operating in parallel forming a MG is considered. Existing MG at Baglung District (Interconnected seven nearby Micro Hydro Plants with cumulative power output of 132 kW) was taken as a reference case for the study. Current active power sharing strategy was realized by considering MG with three generators and new concept was proposed to minimize the existing problem on power sharing. The control strategy is presented only for the MG operated in islanded mode. The case is designed and simulated in MATLAB using Simulink. This study does not consider the reactive power flows and sharing issue. This scheme can be efficiently used in MG Application.","PeriodicalId":261471,"journal":{"name":"2015 9th International Conference on Software, Knowledge, Information Management and Applications (SKIMA)","volume":"56 90 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":"129276463","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}

In this paper we describe how changes in the granularity of the unit of estimation, e.g., work-days instead of work-hours, affects the effort estimates. We describe four psychological mechanisms, how they interact and discuss the expected total effect of higher granularity units on effort estimates. We argue that the mechanisms in general imply that higher granularity effort units will result in higher effort estimates, e.g., that estimating software development work in work-days or weeks will lead to higher estimates than when estimating in work-hours. A possible implication of this predicted effect is that, in contexts where there is a tendency towards under-estimation, estimation in work-days or weeks instead of work-hours leads to more realistic estimates.","PeriodicalId":261471,"journal":{"name":"2015 9th International Conference on Software, Knowledge, Information Management and Applications (SKIMA)","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":"132804060","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}

The increasing demand for these systems impose various challenges, including time bounded services, specific data rates, prioritized data transmission and energy consumption, etc. These challenges maps on the different layers of the protocol stack for WBASNs. In this context, a lot of new protocols for applications, MAC, network and physical layer have been proposed; however, few describe a complete simulation model to evaluate patient monitoring system. In this context, this work examines and proposes a simulation model based on the CASTALIA 3.2 simulator with an OMNeT++ framework to evaluate the patient monitoring system. The proposed model consist of six biomedical sensor nodes, including electrocardiography (ECG), blood pressure (BP), accelerometer, temperature, blood oxygen saturation and glucose monitor. The model defines the data rate settings for these nodes at the application layer. All these nodes are configured in star topology and send data to a centralized controller. IEEE 802.15.4 standard is used for the MAC and PHY layer and ZigBee is used over network layer. Slotted carrier sense multiple access with collision avoidance (CSMA/CA) is used as a channel access mechanism, however, the model also accommodate prioritized channel access by configuring guaranteed time service (GTS) for an ECG node. To evaluate the model, the parameters including delay, packet delivery ratio (PDR) and energy consumption is used. To evaluate simulation model over patient monitoring system, we have considered 250 ms as maximum affordable delay. It is observed that most of the nodes delivered data to coordinator under 250 ms Moreover, for the GTS model, the prioritized node (ECG) shows the acceptable delay and PDR values. Further, GTSon mode utilizes less energy as compared to GTSoff mode. Overall, researchers can use this model as a guideline to evaluate new protocols and standards of WBASNs.","PeriodicalId":261471,"journal":{"name":"2015 9th International Conference on Software, Knowledge, Information Management and Applications (SKIMA)","volume":"71 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":"123584251","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}

The pixels of shares can be generated randomly or the cover image can be used to generate the first share. The encrypted shares generated using cover image seem to be visually less similar to those generated without using cover image. Also, on the basis of image similarity between shares and original image, further encryption of encrypted shares can be performed. Comparison of the outcomes when cover image is used and when not used to generate shares, shows that the latter is more sensitive to the transparency factor (alpha) than the former encouraging the use of properly selected cover image for visual cryptography using pixel transparency.","PeriodicalId":261471,"journal":{"name":"2015 9th International Conference on Software, Knowledge, Information Management and Applications (SKIMA)","volume":"21 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":"127891079","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 is a case study of FIAT dealership, Batas Brothers Motors Pvt. Ltd (BBMPL) based on import of Nepal-India custom. Study includes comparative research design of FIAT general import model, principal standard import model and Database Management System (DBMS) based import model. Input data taken for DBMS model is sales, warranty, clipping, sub-dealership demand data of FY 2069/70 BS, 70/71 BS (2013/014 AD, 2014/2015 AD). These data are used to forecast demand, cost of freight and custom duties for FY 2071/72 and determine the import time information. An accumulated order of forecasted data is generated by DBMS Model for study of time comparison with standard import model and general inventory model. Statistical summary of study shows that general inventory model takes 2.4 times (108 days) longer duration than that of standard import model i.e, 45 days whereas DBMS model reduces standard time by 0.57 times (26 days). The study suggests DBMS inventory model as best model in comparison with standard import model and general inventory import model. Web based application software of DBMS based inventory model has been developed and its reliability test in import management has been carried out. The model is friendly in business intelligence (BI) and enterprise resource planning (ERP) for import industry. If database of spare parts demand viz-normal workshop sales, warranty sales, clipping sales, sub dealership sales can be collected, the model can be effectively used in other industries also, beside the automobile service.","PeriodicalId":261471,"journal":{"name":"2015 9th International Conference on Software, Knowledge, Information Management and Applications (SKIMA)","volume":"22 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":"126181157","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}

Everyday people spend a great amount of their time in the virtual world through various online social networking sites. As a result a huge amount of personal information is being exchanged over the social network making them top of the interest to researchers from every field, various application developing companies, advertising companies and even governments. Analysis of these graphs helps discover invaluable knowledge. But this boon does not come without curse. Many invasive adversaries threat the confidentiality of this private information making the users vulnerable to being exposed and identified. So preserving privacy while publishing the social network graph data is one the most important concerns in today's world. Different technique has been adopted to anonymize social network data before publishing. In this paper we have proposed an iterative algorithm to generate k-anonymize vertex degree sequence of a given social network graph in order to protect the graph against passive attack. We have applied our method to some social network graph datasets and demonstrated their efficiency in preventing vertex re-identification attacks where an adversary has background knowledge about the degree of the target vertex.","PeriodicalId":261471,"journal":{"name":"2015 9th International Conference on Software, Knowledge, Information Management and Applications (SKIMA)","volume":"89 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":"130479648","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}

Rapid and precise reliefs delivered to right victims are the key to improve situation after an unavoidable disastrous event. This is one of a great challenge in rural area of most developing countries as all required resources can be lacked in any moment. At the same time, there is a lot of observed information from many different sources which has to be manipulated while the relief is indeed required in the timely manner. The observed information can be over and under estimated because it depends mainly on the individual observers. Therefore to promote effective disaster relief management system, this paper presents a system for crosschecking and ranking the collected information from multiple observers to sort victims based on their priorities. The proposed system consists of three main components: the case gathering service, the crosschecking mechanism and the ranking process. Based on information of a real disastrous area suffered by the earthquake in Chiang Rai province which is in the northernmost of Thailand in 2014, the proposed system is evaluated as high availability, moderate satisfaction along with high adequate precision.","PeriodicalId":261471,"journal":{"name":"2015 9th International Conference on Software, Knowledge, Information Management and Applications (SKIMA)","volume":"7 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":"121148298","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 CPS is the integration of computational elements with physical processes. One of the most widespread application of CPS is the autonomous transportation systems. This paper presents a CPS model for the design of a platoon system approach (i.e. a set of autonomous vehicles that move together without any mechanical link while maintaining a predefined configuration). The proposed approach to platoon issue can be considered to be decentralized since each vehicle perceives its environment and acts based only on its own perceptions. The proposed approach deals with different platoon formation. The vehicles of the platoon are able to maintain their position in the configuration while avoiding collision with obstacles. The paper shows some simulation and experimentation results that allow to evaluate the quality of the proposed platoon approach.","PeriodicalId":261471,"journal":{"name":"2015 9th International Conference on Software, Knowledge, Information Management and Applications (SKIMA)","volume":"45 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":"125619151","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}
