Photovoltaic Cells are leading this revolution by harnessing the power of the sun and transforming it into DC power. Integrating this “too good to be true” power source into the grid has been in the mind of those who plan for future grid alterations for a while and the need for seamless integration has arrived. Power systems and power-flow through the grid are planned precisely and do not respond well to sudden changes. Large-scale PV grid integration is challenging and requires preparation to deal with the intermittency of power production. This paper analyzes an IEEE 21-Bus power system with regards to power-flow and small to large scale integration of PV generation. The pros and cons of this addition are researched and documented here as well as simulations of PV integration using Matlab's Power System Analysis Toolbox (PSAT) software. There are a few correction methods that attempt to solve some of the known problems with adding solar generation into the grid such as tap-changer transformers, capacitor banks, and synchronous condensers. Besides normal analysis, this paper also presents one of these correction methods into simulation to show how part of the large-scale integration problem can be corrected.","PeriodicalId":368197,"journal":{"name":"SoutheastCon 2017","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129795013","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}

Several research programs have been established to monitor honeybee hives and to understand the behavior of the bees. A reliable monitoring system is important as it provides the beekeepers an opportunity to remotely observe the progress of their hives without the need to actually open them. This paper will present the results of several years of study and investigation for creating a reliable and inexpensive hive monitoring system. Our goal has been to create an inexpensive and modular system which sends sensor data acquired from beehives to a server for further analysis. Our initial efforts utilized video surveillance system but evolved to a more reliable system that utilizes Raspberry Pis and ATmega328Ps as its framework. This paper will provide details on the initial system and how it evolved to a new system that we are calling Beemon with its data acquisition capabilities. The early video and audio recordings obtained by the system are used in some image and signal processing analysis which are not presented on this paper.","PeriodicalId":368197,"journal":{"name":"SoutheastCon 2017","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128527676","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 parasitic resistances are difficult to determine because no convenient analytical expression is available to calculate this resistance. However, electrical current entering a circular contact uniformly from all directions can be modeled using analytical expressions. Here we present a new test structure where parasitic resistance can easily be calculated because it occurs between concentric equipotentials. This resistance is then subtracted from the total resistance to give the resistance due to the contact interface and hence the specific contact resistance of that interface. Using aspects of the CKR and the Circular Transmission Line Model (CTLM) we have designed a new test structure, here called the Circular Cross Kelvin Resistor (CCKR) test structure for determining specific contact resistance.","PeriodicalId":368197,"journal":{"name":"SoutheastCon 2017","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129543553","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 identification is centered around an id-case, a set of situations leading up to a judgment of agent identity. The id-case consists of an id-situation, where the actual judgment is made, and a number of resource situations, which support the id-situation. The notion of situations used is based on Barwise and Perry's situation theory and expressed using semantic web notation. Each id-case corresponds to a justification-based mass function, which can be combined with other mass functions using Dempster-Shafer theory. This paper explores the relation between the id-situations, which provide similarity measures that serve as a basis for an initial mass function, and resource situations, which can modify that mass function in a number of ways.","PeriodicalId":368197,"journal":{"name":"SoutheastCon 2017","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125396708","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}

We demonstrate via experiments that cooperative robots can be used to autonomously transport an object that is too heavy or cumbersome for a single robot to do individually using minimal inter-vehicle communication. The proposed control strategy is divided in three phases: contact, re-orientation, and cooperative transportation. The first two phases consist of driving the robots from any arbitrary initial configuration toward the object, establishing physical contact with the object, and re-orienting themselves according to the objects desired destination. The third phase consists of cooperatively transporting the object by assuming a novel inter-vehicle topology. The two first phases require initial inter-vehicle communication, whereas the third phases assumes that each robot is rigidly connected to the object. Collectively, these results demonstrate the ability to transport an object using multiple robots with minimal intervehicle communication.","PeriodicalId":368197,"journal":{"name":"SoutheastCon 2017","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116735084","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}
