The predictive model is trained using dam daily average inflow observations inclusive of years 2003 to 2012, as recorded. Any real-time inflows forming a 5-consecutive-day vector could serve as input to the regression process. Its predictive power as measured by correlation coefficient at 0.959 for observed and predicted inflows taken from blind test set as well as 0.925 from validation set, could provide model users better perspective and outlook with regard to reservoir inflow conditions 24 hours into the future. In the background, this proposed model can offer dam managers protracted time in arriving at optimum reservoir water storage estimation as well as in load dispatching and scheduling when integrated into a decision support application.","PeriodicalId":309548,"journal":{"name":"2014 International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment and Management (HNICEM)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127930830","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 system begins with a microcontroller unit having an analog voltage input that is derived from a calibrated linearity curve relative to that of glucose concentration, the microcontroller algorithm processes the data and determines whether an output of insulin or glucagon is needed. The output of the microcontroller unit is a time variable pulse which is dependent on the glucose concentration reading. Separately, a full custom IC design is conducted for an actual drug driver circuit for the purpose of miniaturization to make the system viable for implantation. The hardware test for the microcontroller unit indicates that the algorithm can be used to properly read glucose concentrations and provide an output accordingly. However, there are delays within the microcontroller which affect the response of the output. For the full custom IC design of the drug driver circuit, it is observed that the parasitic capacitances and resistances affect the propagation delay and power dissipation of the circuit but can still be used in a drug driver system.","PeriodicalId":309548,"journal":{"name":"2014 International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment and Management (HNICEM)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132142486","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}

Aggregation is the ability to gather swarm members around a specific point in space. The goal is to keep an object, stationary or moving, at the center of the swarm. This paper presents a novel approach to centroid tracking in robotic swarms. Genetic algorithm is used in quadrotor unmanned aerial vehicles to keep the object being tracked at the center while minimizing two parameters: the distance travelled by each quadrotor and the distance of each quadrotor from the object. Centroid tracking was found to have an average error of 0.0623568 units for swarm populations ranging from 10 to 100 with the lower swarm populations exhibiting lower errors. Convergence did not exceed the maximum of 23 milliseconds for populations less than 30. These results show that the algorithm is well-suited for implementation in swarms with lower numbers of quadrotors.","PeriodicalId":309548,"journal":{"name":"2014 International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment and Management (HNICEM)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134380173","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}

Carbon fiber reinforced polymer (CFRP) wraps and fiber-reinforced mortar (FRM) jackets were used as retrofitting materials. Steel fibers, synthetic fibers, and cellulose fibers were added as reinforcement to mortar that is used as retrofitting jacket for reinforced concrete columns. To evaluate the effectiveness of these retrofitting techniques, column specimens were prepared and tested. The test results of 9 column specimens with synthetic and cellulose fiber-reinforced mortar jackets, 12 columns with steel fiber-reinforced mortar jackets with 3 different volume fractions (1%, 2%, 3%), and 9 columns retrofitted with CFRP wraps were investigated. The column specimens had square sections with 4-10mm diameter steel as main bars. The dimensions were limited to the size that can be accommodated for axial testing up to failure using a Universal Testing Machine. The confinement effect was quantified by obtaining the individual contribution of each material that comprised the reinforced concrete column specimen and subtracting them from the actual load being resisted. This was done by monitoring the strains of the steel and concrete and relating the measured values to the stress-strain relationships of the materials. The percentage of the confinement effect was obtained in order to evaluate the effectiveness of the contribution of the different materials used in retrofitting techniques. The paper presents the results of the experimental program including the corresponding analysis and comparison of the effectiveness of the different retrofitting materials.","PeriodicalId":309548,"journal":{"name":"2014 International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment and Management (HNICEM)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126348392","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}

Though foreign exchange rates vary on a daily basis, the output of this paper is prediction of the average foreign exchange rate every month. Artificial Neural Network serves as a powerful tool in forecasting Philippine Peso to US Dollar exchange rate not requiring expert knowledge in banking and finance thus letting the public gain access to a helpful beacon which is the foreign exchange rate. However, the accuracy of the forecast using artificial neural network is highly dependent on the volume of the training data, in this paper, an alternative algorithm that will increase the accuracy of the conventional artificial neural network with limited volume of training data is presented and analyze.","PeriodicalId":309548,"journal":{"name":"2014 International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment and Management (HNICEM)","volume":"26 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133321062","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}

Ideally, it is good for the mobile phone shops to display different models in their stores and have stocks of these models in order to attract customers. However, the problem in that concept is stocking inventory will cost a lot of money. Mobile phone stores often have limited resources so it is ideal to balance the quantity and specification of their units. Given the budget constraint, the specifications of the parts of the mobile phones that will be purchased have to be optimized. The owners of mobile phone stores often do it manually and without scientific basis which lead to inefficiency. This research shows a scientific approach in minimizing the average annual cost of ordering and storing mobile phone sets. This is done by using Particle Swarm Optimization in purchasing the number of units and the specifications of their components.","PeriodicalId":309548,"journal":{"name":"2014 International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment and Management (HNICEM)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133347356","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}
