<![CDATA[In daily life, it is often found that office buildings and shopping centers use air conditioning system (AC Central) for room cooling. The refrigerant in the cooling system releases the heat into the air with the help of the motor fan. In order to release the heat faster, the condenser pipe winding is designed and equipped with fins. The heat released from the condenser will be discharged to the air. This will lead to global warming if large numbers of air conditioning system are used. In this case, thermoelectric technology is a main alternative solution that can be implemented. Thermoelectric converts heat energy directly into electrical energy. Therefore, in this paper, we design a simple power system by utilizing waste heat energy from a condensor based on thermoelectric method. Based on the result of the experiment, an average temperature of 34°C results in voltage of 3.14 Volts and power of 0.16 Watts.]]>

<![CDATA[Wireless network uses transmission media based on radio waves. This type of networks is mainly useddue to its efficiency and mobility in data exchanging. This paper reports the modeling and simulation of wirelessnetworks based on Cisco Aironet 1130ag access point devices with IEEE 802.11a and IEEE 802.11g standards. Themodeling and simulation are performed using network simulator version 2 (NS-2) that is installed on operationsystem Linux Ubuntu v.10.10. The NS-2 is commonly used and works well in numerous types of network simulation. From simulation, we obtain quality of service parameters by employing several simulation scenarios in terms ofnumber of nodes, distances, and packet data sizes. It can be concluded from simulation results that the IEEE 802.11gnetworks transfer data with better quality than those of IEEE 802.11a networks. Furthermore, the IEEE 802.11gnetworks provide a higher throughput, with smaller amount of delay and packet loss percentage compared to thoseof IEEE 802.11a networks.]]>

<![CDATA[In the past few years, cloud computing has became a dominant topic in the IT area. Cloud computing offers hardware, infrastructure, platform and applications without requiring end-users knowledge of the physical location and the configuration of providers who deliver the services. It has been a good solution to increase reliability, reduce computing cost, and make opportunities to IT industries to get more advantages. The purpose of this article is to present a better understanding of cloud delivery service, correlation and inter-dependency. This article compares and contrasts the different levels of delivery services and the development models, identify issues, and future directions on cloud computing. The end-users comprehension of cloud computing delivery service classification will equip them with knowledge to determine and decide which business model that will be chosen and adopted securely and comfortably. The last part of this article provides several recommendations for cloud computing service providers and end-users.]]>

<![CDATA[This paper proposes design and implementation of a 16-bit multiplier based upon Vedic mathematicapproach, where the design has been targeted to the Xilinx Field Programmable Gate Arrays (FPGAs) board, deviceXC5VLX30. The approach is different from a number of approaches that have been used to realize multipliers. Ithas been reported that previous algorithms such as Booth, Modified Booth, and Carry Save Multipliers only suitablefor improving speed or decreasing area utilization; therefore, those algorithms are not appropriate for designingmultipliers that are used for digital signal processing (DSP) applications. Moreover, they are not flexible to beimplemented on FPGAs or on a single chip using application specific integration circuits (ASICs). Vedic approach,on the other hand, can be used to design multipliers with optimum speed and less area utilization. In addition, it isreliable to be implemented on FPGAs or on a single chip. Behavioral and post-route simulation results prove that theproposed multiplier shows better performance in terms of speed compared to the other reported multipliers whenbeing implemented on the FPGA. In terms of area utilization, better results are also obtained.]]>

<![CDATA[This research is motivated by electrical power shutting-down that frequently occurred in Riau province. Low electrical power supply as compared to the need causes lack of supply. Thus, new alternative electrical energy resource such as micro hydro is required. Micro hydro plant is an electrical power generators that uses water to rotate the turbine. This research designs a monitoring system for micro hydro plant. The monitored micro hydro plant employs water turbine that is constructed using bicycle pedal and a water pipe installed on the pedal . The pipe flows the water to energize the turbine. Turbine rotation will generate electricity. The amount of power resulted by generators depends on the number of turbine rotation. The power is used to turn on the lamp. Some sensors are used to monitor generator performance. Current, voltage, and rotation sensors are used to monitor the resulted current, voltage, the turbine rotation respectively. The output power is stored in the battery. The micro Arduino and the ethernet shield capture the monitored data and send it to the computers using Wi-Fi connection. Measurement results show that the output voltage produced by the generator is 10 Volts when the water volume is high. Finally, it is found that the micro hydro generator is able to supply 5 Watts to the load.]]>

<![CDATA[In this research, a mini boiler temperature control system is designed by using fuzzy logic controller (FLC). The FLC controls the valve of the incoming fuel. The mini boiler is fueled by gas, has length of 80 cm and diameter of 40 cm. FLC is designed in four different models based on the number of membership function of the temperature variable, i.e., three, five, seven and nine membership functions. The input variables are “temperature” and “error”, and the output variable is “valve”. There are two types of disturbance given to the control system, the disturbance of the system working at set point 125 °C, and disturbance by changing the set point values. In the first type, the FLC is able to reach 125 °C for all models. In the second type, the set points are varied to 100 °C, and 150 °C. At set point 125 °C and 150 °C, the FLC is able to achieve the pre-determined set points for all models. Mean while at set point 100 °C, the FLC can stabilized the system at point of 97.92 °C for the first model, and at the point of 100 °C for other models.]]>
