Dengue fever disease had threatens more than 4 billion people worldwide. Current studies in this disease focus on the relation between environmental data and dengue cases directly without considering the stage of the mosquito's life. In fact, dengue case is associated with different dominant stages under different circumstances. Therefore, it is important to analyze and select the dominant stage of mosquito for different situation to select an adequate strategy for disease-spreading prevention. In this research, we introduce the new system to select the stage based on context-dependency by using Mathematical Model of Meaning (MMM).The feature of this research is in calculating the similarity pattern analysis between environmental data with disease stage. The objective of the research is to build effective prevention system due to dominant mosquito's stage that possible to trigger dengue case. In this study, we focus on abiotic contexts with features such as rainfall, temperature, humidity, sunshine duration, CO2 and wind speed. This model consist of (a) subspace creation based on stage classification from ecological model of dynamic energy budget, (b) context-similarity calculation by using MMM, and (c) matching-prediction by Hilbert Transform. Through this system, we can determine an effective strategy to prevent dengue case in every different situation. Therefore, this system can contribute to reduce environmental damage and probability of health problem caused by an improper strategy of disease prevention. In this research, we employ real weather data of Surabaya from 2007 to 2011. The result shows that the dominant stage in wet season and dry season is different, also in specific case such as disaster, the dominant stage also different.

Shape-based boundary representation is a critical component in medical imaging-based diagnosis system. Furthermore, accurate boundary representation is also essential in getting good segmentation, feature indexing and classification. This work concentrates on cervical vertebra distortion across the anterior boundary to detect anterior osteophytes and identify its severity. A suitable shape representation, which defines the vertebrae shape boundary must be determined prior to the cervical vertebra model can be constructed. Therefore, two different shape-based representations for vertebral segmentation using active shape model are analysed, which are 9-anatomical point representation (9-APR) and B-spline representation (BSR). The aims is to compare and quantify the precision and accuracy performance of the segmented vertebra with the help of orientation histogram-based indexing and multi-layer perception based on ten-fold cross validation (MLP-TFCV) classifier. Experimental results are assessed based on the segmented boundary outline by using ROC and AUC curves. The results show that the performance of both boundary representations are almost similar where B-SR has a small advantage compared to the 9-APR. The system can be further improved by introducing a statistical sampling method of the anterior points instead of the whole vertebra.

In a radio station when the announcer wants to Broadcast an urgent message to the listeners, the announcer must set manually the volume of background music while it has been playing. This process has disadvantages such as the volume of background music being either too loud or too weak. This effect can be minimized by adjusting music volume automatically using human speech signals. In this research TMS320C6713 DSP Starter Kit (DSK) as a signal processor is used. The incoming human speech signal will be detected by using voice activity detection (VAD) which consists of Short Term Energy and Zero Crossing Rate, the process is to identify the characteristics of the human speech signals. If the input signal is the human speech signal it will affect to decreasing volume of background music and will be maintained at a certain minimum level during speech. By using an energy threshold value of 60 dB and ZCR values between 20 and 45 times the system can recognize the input signal and the signal is human speech signals. Furthermore, voice signals can be used to adjust the volume of the background music as a given gain parameter.

Mobile peer-to-peer (P2P) network is a simple computing network in which some of the mobile devices are communicated with peer-to-peer mode through access point. Energy efficiency in mobile P2P is improved by increasing the number of active nodes on the network and reducing the consumed energy by the number of idle nodes. However, if a lot of the number of active nodes perform the transmission process, it can cause interference between stations which could decrease the network performance. Therefore, this paper evaluates the effect of channel condition and bandwidth on mobile P2P networks towards energy efficiency. This can be done by analyzing the relationship between the parameter of channel conditions such as channel quality and network energy consumption. Another parameter that affects the energy efficiency is the availability of bandwidth in the network, which can be obtained by using different modulation types that are BPSK and QPSK. To evaluate the parameters, a model for P2P network is introduced into three different scenarios of information transmission processes. Numerical simulation has carried out using Matlab programming. Simulation results show that energy efficiency is inversely proportional to the quality of the channel, where the high channel quality has small energy efficiency in the network. In addition, QPSK modulation could provide a significant improvement on the energy efficiency for mobile P2P network compared with BPSK modulation.

Power quality in hybrid wind turbine system with diesel (wind-diesel) affected by change of frequency fluctuation. Low - frequency oscillation due to the transmission network is long and low time constant and the high gain Automatic Voltage Regulator (AVR). Hybrid wind turbine system with diesel (wind-diesel) is controlled by Proportional Integral Derivative (PID) controllers. Trial - error method is used to determine the value of the gain of PID, so it is very difficult to get the optimum value. Study on the design control using Artificial Intelligent (AI) algorithms to find the optimum value of firefly from gain PID. The optimum value of the PID gain is used to adjust the frequency of the load with the matlab Simulink program. Hybrid wind turbine system with diesel (wind-diesel) with PID - firefly has a response which indicates that large overshoot and settling time response is being reduced and faster than a hybrid wind turbine system with diesel (wind-diesel) with PID trial-error.

Wireless Sensor Network (WSN) is a promising technology for many applications, such as industrial, environment, and health-care application. The first requirement of WSN is energy efficiency in order to increase the network node lifetime. The second is reliability because packet drop cannot be tolerated in critical time applications. In this paper, we use NS2 simulation to evaluate and analyze the IEEE 802.15.4 standard in multi-hop WSN with a tree topology base on IEEE 802.15.4. Beacon enabled mode is used slotted CSMA/CA and non-beacon enabled mode is used unslotted CSMA/CA. Performance of beacon enabled and non-beacon enabled were evaluated and analyzed to understand the impact of protocol parameters such as Superframe Order (SO), Beacon Order (BO), and Traffic Load. The performance of the network which have been evaluated in detail are the throughput, energy consumption, end to end delay, packet success probability, drop packets and the percentage of the energy efficiency. The simulation result show that of beacon enabled is better than non beacon enabled in terms of the throughput, drop packet, energy consumption, and energy efficiency.

Tomography is a method that can reconstruct the internal image of a non-invasively object, based on the measurements. On acoustic tomography, measured data is obtained from the output of ultrasonic transducer that is passed to the object. Velocity of waves that pass through the object is processed to obtain the impulse response and sampling projection. Once processed by the FFT, both these quantities is filtered by the back projection filter to obtain image reconstruction. This method that conducted to the air, water, mud, aluminum, and the combination of those materials, will showed gradations of color in the image in the form of a mesh, contour, pcolor, and surface. This shows the velocity difference when the ultrasonic wave reflected or transmitted by the material of measured object that can be indicated as the difference in the substance of the material in the measured object.

Using femtocell in LTE with small coverage area is considered have more effective performance than Macro BTS (eNB). However, using femtocells (HeNB) in LTE will make interference problem among femtocell (HeNB) to the Macro BTS (eNB). Femtocell is a source of interference for users who cannot access it. Therefore it is necessary for interference coordination methods among the HeNB and eNB. The methods are ICIC (Intercell Interference Coordination) and eICIC (enhanched Intercell Interference Coordination). ICIC method is using frequency resource allocation that allocating every user in different subcarrier. eICIC method is allocating almost blank subframe (ABS) in time domain resource for macro user that got interference from femtocell (HeNB). Simulation result in frequency resource allocation using ICIC method can increase SINR 43.04 % and throughput 23.09 %. However using eICIC method in time domain resource can increase performance of SINR 54.32 % and throughput 74.78 % that is better than frequency resource allocation.

However, using femtocells (HeNB) in LTE will make interference problem among femtocell (HeNB) to the Macro BTS (eNB). Femtocell is a source of interference for users who cannot access it. Therefore it is necessary for interference coordination methods among the HeNB and eNB. The methods are ICIC (Intercell Interference Coordination) and eICIC (enhanched Intercell Interference Coordination). ICIC method is using frequency resource allocation that allocating every user in different subcarrier. eICIC method is allocating almost blank subframe (ABS) in time domain resource for macro user that got interference from femtocell (HeNB). Simulation result in frequency resource allocation using ICIC method can increase SINR 43.04 % and throughput 23.09 %. However using eICIC method in time domain resource can increase performance of SINR 54.32 % and throughput 74.78 % that is better than frequency resource allocation.","PeriodicalId":248906,"journal":{"name":"2015 International Electronics Symposium (IES)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121917102","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}
