In contrast, due to significant variability of flows in space and time, an extensive modeling effort must be accommodated with the application of parallelization technology. Therefore, the implication of estuary model parallelization to the model result uncertainty must be examined. In this research, a three dimensional (3D) hydrodynamic model of Columbia Estuary, located in Oregon, United States, was configured in cloud computing environment. The case study was simulated using DFlow Flexible Mesh software from Deltares. The model behaviors were evaluated in terms of water level, velocity, and salinity with the reverence of field observation data. The estuary model was calibrated in respect to physical parameters before parallelization process. Through calibration procedure, it was revealed that the model were sensitive to bed roughness, eddy viscosity coefficient, and eddy diffusivity coefficient. It can be concluded that the model parallelization technique had induced minor uncertainty contribution to the specific estuary model results. The pattern of uncertainties are varies within the range of parallel processes scenarios, as a result of automatic domain decomposition practice that produces additional diffusivity term to model. Meanwhile, there is an optimum parallel process scenario with minimum computational time. Some bargaining alternatives between model uncertainty and computational time are presented for the application of estuary parallel modeling.","PeriodicalId":148115,"journal":{"name":"2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127055358","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 proposed solution of this problem is executed by using a filter and a transformation matrix. The filter is used to generate the dynamic of system errors. Moreover the scheme consists of two stages. The first stage is to generate bases of each row of the transformation matrix so that they robust to structured uncertainty for each eigenvalue of the filter. The second stage is to construct row by row the transformation matrix based on the designed of signature vectors such that the modes of residual sensor fault can be decoupled one from the others. Moreover one dimensional of detection space is developed. To demonstrate the effectiveness of the method a simulation study on a MIMO Web Winding System which has multi input and multi output is carried out. The result shows that the method has been successfully implemented.","PeriodicalId":148115,"journal":{"name":"2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134592496","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 order to decide an appropriate decision, such a system needs surrounding contexts, such as location and activity that are obtained from sensors around the environment. We propose a novel infrastructure-less occupant context recognition, where we only need off-the-shelf sensors in a mobile device to recognize room occupancy. The idea is to derive the occupant context from user position gathered by real time Dead Reckoning (DR) technique on a mobile phone. Moreover, our system is able to control electrical devices based on the occupant context in certain room. Our experiments in a laboratory environment show that it can be really implemented and prospectively replacing Passive Infrared (PIR) sensors in occupancy detection due to smaller delay compared to 10 seconds timeout which is commonly determined by many energy-efficient systems based on PIR-sensor to reach the unoccupied state.","PeriodicalId":148115,"journal":{"name":"2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132757019","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}

Currently, Indonesian grid capacity is just over 43 GW and estimated to reach over 65 GW by 2025 hence renewable generation target is around 6.5 GW. Indonesia is an archipelago country with over 13,700 islands stretches from east to west over three time zones. Renewable generation should be developed over 34 provincial regions by utilizing local resources. Bali is small island and one of provincial administration with nearly four million population and land area of 5,600 square kilometer. As of 2013, its electrification ratio has reached 98%. Its power system is supported by 759.5 MW generating capacity but with peak load already at 730 MW. Bali does not have conventional resources hence all fossil-based fuels are sourced externally. Fortunately, Bali has various renewable resources that can be harnessed for electricity generation. Renewable resources available on the island are micro hydro, wind, photovoltaic, biomass, and also geothermal. This paper provides updated information on the potential and progress of renewable generation of the island. As of 2014, total renewable generation plants has reached 7 MW. The plants comprises of 2.1 MW photovoltaic, 736 kW wind power, 45 kW micro hydro, and 4.174 MW waste-to-electricity plants. The renewable generation contributes to around 1% of Bali's total power capacity.","PeriodicalId":148115,"journal":{"name":"2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124017866","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}

From these measurements, the relationship between axial position and clamping force in the range of 0 to 20 kN is established. A force sensor is placed between two movable pulleys to measure the clamping force, while an incremental encoder of 500 pulses per revolution is attached to the pinion shaft to indirectly measure the axial pulley position. Measurements are done using Matlab/Simulink© program and Arduino Uno based data acquisition system. The experimental results show that when the clamping force is between 0 and 10 kN, the relationship between clamping force and axial position can be approximated using third-order polynomial equation with an average error of 0.35%, while between 10 kN and 20 kN, the relationship can be approximated using a linear equation with an average error of 0.02%. Based on this relationship, the calibrated position sensor could be used to replace the force sensor to indirectly measure the pulley clamping force.","PeriodicalId":148115,"journal":{"name":"2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128136051","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}

Bluetooth technology is chosen to provide reliable communication system with low complexity and production costs. To assess connection among the predefined sensor positions in car, the RSSI (received signal strength indicator) measurement is conducted by using the HC-05 Bluetooth module as the receiver and Android smartphone as the transmitter. The measurement scenario is defined based on the link between master-station at car dashboard to all possible sensor positions. More measurements are also conducted for the coverage of Bluetooth connection in the possible longest distance of car dimensions. The measurement results show that the RSSI receptions from all sensor nodes are higher than the used receiver-sensitivity threshold. Therefore, the implementation of Bluetooth is feasible. However, in the real application, the sensitivity of the implemented Bluetooth module should be carefully considered because the signal reception has possibility to drop below typical threshold in the Bluetooth standard. Therefore, rigorous measurements assuring that all possible sensor placement scenarios should be guaranteed to result in RSSI higher than the threshold of the implemented Bluetooth hardware.","PeriodicalId":148115,"journal":{"name":"2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130297249","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}
