This paper discusses the comparison of 4 (four) types of modulation used in WAIC technology. WAIC (Wireless Avionics Intra Communications) is a new wireless system that connects avionics over short distances in the aircraft. The technology was proposed by ITU (International Telecommunication Union), ICAO (International Civil Aviation Organization), AVSI (Aerospace Vehicle Systems Institute), and aircraft manufacturers. The various kinds of modulation give significant impact to required WAIC spectrum. Subsequently, such factor is also determined by the modulation efficiency that is unique to the type of modulation. This paper investigates the modulation trade-offs that must be fulfilled to gain optimum result. These optimum results are the key findings to determine the spectrum and the number of OPS (Omnidirectional Point Source). The parameters being simulated are power, modulation efficiency, BER, and the total spectrum needed. The result shows that QPSK is the best proposed modulation respected to the most optimum simulation results. In conclusion, QPSK could be used as the modulation system used in WAIC technology.

In this paper we present the characteristics of leakage current at different shed of epoxy resin insulator under rain contaminants. The aim of this paper compared the leakage current characteristics under rain contaminant and dry test. Also it compared when used same and different sheds. The tests were conducted at high voltage laboratory with AC high voltage 50 Hz. Leakage current characteristic of 20 kV outdoor insulators with epoxy resin has been investigated under dry and rain contaminant condition. The chamber was used to placing the insulator. The research results showed that the leakage currents characteristics on insulator surface were affected by rain contaminant and form of shed. A minimum leakage current achieved at outdoor insulator without contaminant or dry test conditions. For outdoor insulator under rain contaminant test, the characteristics of leakage current tend to increase. Shed form of insulator influences the characteristics of leakage current also was analyzed.

This paper discusses the architecture and implementation of system-on-chip (SoC) for noise cancellation system which uses Variable Speech PDF and MAP Estimation as noise cancelling algorithm. The hardware software co-design approach is used to achieve real-time performance while considering ease of implementation and design flexibility. The software module utilizes LEON SPARC-v8 and FPU co-prosessor as processing unit. The AMBA based Hanning Filter and FFT/IFFT are designed as processing accelerator module to increase system performance. The FFT/IFFT module uses custom Radix-22 Single Delay Feedback (R22SDF). In order to provide high data transfer rate between buffer and hardware accelerators, the DMA controller is also designed. The overall system implementation utilizes 18,500 logic elements and uses 21.87 kB of memory. Latency of the system is 0.69 ms so the system can be run in real-time. The system is implemented on FPGA Altera DE2-70 with both algorithms and the noise cancellation function has been verified.

Wireless Mesh Network (WMN) relies in routing protocols for route discovery from sender to receiving nodes. There are two routing protocols that are evaluated: Hybrid Wireless Mesh Protocol (HWMP) and Optimized Link State Routing (OLSR). Packet delivery is very crucial in telecommunication. Data rate of connections relate closely with the performance of packet delivery in telecommunication especially WMN. HWMP and OLSR have different mechanisms of route discovery which are affected by the changes of data rate of connections and can affect the packet delivery of data. This experiment focuses in evaluating the performance of both protocols under different conditions of data rate of connections. The objective of this experiment is to evaluate the performance of both protocols and find the relevancy between the results of simulations and theories of the mechanism of both protocols. All of the simulations are done with using Network Simulator Version 3. The simulations are done for more than 100 times in order to get the consistency of the results of simulations and to evaluate the natural behaviors of both protocols.

Transceiver radio is a commonly used wireless telecommunication system that establishes two-way communication in a relatively far distance without any cellular cost. However, radio communication needs a good antenna for transmitting and receiving well in both way. In this paper, a dual band J-Pole antenna for VHF and UHF transceiver radio communication was simulated and implemented. This antenna was designed for frequency of 146 MHz and was able to resonate well at UHF band by adding a “T” shaped compensating element. The material used was 4 mm iron wire. The J-Pole-T antenna performance was measured to get the resonant frequency, VSWR, and radiation pattern. Based on test results, the J-Pole-T antenna was resonating at frequency of 148 MHz with VSWR 1:1,1, while at the UHF band of 454 MHz with VSWR 1:1,05. The radiation pattern of J-pole-T antenna showed an omnidirectional shape. The testing result also revealed that the J-Pole-T antenna could transmit and receive radio signal as well.

Post-harvest problems faced by farmers are drying grain. Traditional drying method, low-cost (dried) or use the dryer does not provide a perfect drying results. This is due to the two methods are not able to regulate the temperature, moisture content and humidity levels of the air to the right. As a result of the rice produced has a low quality, easily broken and destroyed during grinding. On the other hand, the existing grain dryer technology is still costly. These things make farmers reluctant to use the existing dryer. Wireless Sensor Network (WSN) have the ability to regulate temperature, moisture content and humidity levels of the air to the right. WSN utilization in grain dryers can provide solutions to improve rice quality and efficiency of the drying process. To improve energy efficiency, husk charcoal briquettes used as fuel grain dryers. Therefore, in this study with a grain dryer technology made husk charcoal briquettes as an energy source based Wireless Sensor Network (WSN) to improve the quality of the rice, so in the end product technology is acceptable to the community and is able to be mass produced. Supervised learning is used in smart system of grain dryer technology to learn grain characteristics.

CMAC is an artificial neural network that uses a postulate of the cerebellum model as its basic structure. This network has a unique address mapping that provides a condition to learn fast and to store information efficiently. By utilizing the features, this paper implements CMAC for sequential images coding. In the encoding process, the pixel position (row, column, and frame) and the pixel value are used in training as input and output, respectively. The trained weights are then quantized to be the encoded data. In the decoding process, weights, which obtained through de-quantization of the encoded data, are used to reconstruct sequential images. Compression achieved because the bit allocation for weights is smaller than for sequential images. In addition, a frame (or a region of interest in a frame) can be retrieved easily from the encoded data by passing spatio-temporal positions to the output mapping in the decoding stage. This paper also compares the performance between the CMAC-based coding and the block-based coding of MPEG. Results show that the CMAC-based coding increases the performance of the mean square error per frame (factor of 28.1 %), frame rate (factor of 14 %), and perceptual quality (factor of 24.4 %).

Safe operation of elements of power systems plays a crucial role in maintaining the reliability and safety of the system. Transformers being a key element in power systems need to be maintained and monitored on a regular basis. Dissolved gas analysis has been used as a reliable tool in maintaining the safe operation of transformers for a long time. Analysis of dissolved gases is analytical and often interpreted differently by different users and methods. The scope of Artificial Intelligence tools in dissolved gas analysis has become critical with increasing number of transformers being used in power systems coupled with rapid expansion of transmission and distribution components. In this work we have designed an analysis system based on different Artificial Intelligence methods like Neural Networks, Fuzzy, and Adaptive Neuro-Fuzzy for analyzing dissolved gas and give interpretation about possible faults. Adaptive Neuro-Fuzzy Inference System (ANFIS) modeling technique has emerged as one of the soft computing modeling technique for power transformer. The objective of this paper is to design an ANFIS model for dissolved gas analysis of power transformers. The prediction ability of the ANFIS is also tested using limited data set for model training.
