Safety and security aspects of radioactive substances from the sender to the receiver are important and should be assured. This research proposes implementation of modified Vernam algorithm to encrypt SMS which contains status information in transporting radioactive substances The results show that there are no errors in the process of data encryption and decryption as long as it uses the same key. In addition, the computational time required to perform encryption and decryption of 1 character is 0.83 ms. Using modified Vernam algorithm will increase the security level of data but must be paid with additional computing time and success rate depends on the similarity of randomly generated key.

Human computer interaction has a long history to become more intuitive. For human being, gesture of different kind is one of the most intuitive and common communication. However, vision-based hand gesture recognition is a challenging problem, which is involved complex computation, due to high degree of freedom in human hand. In this paper, we use hand gesture captured by web-cam instead of mice, for natural and intuitive human-computer interaction. Skin detections method is used to create a segmented hand image and to differentiate with the background. A contours and convex hull algorithm is used to recognize hand area as well as the number of fingertip of hand gesture image to be mapped with button. Moreover, for detection of hand gesture motion, we use Lucas-Kanade pyramidal algorithm. The result shows that this system can operate well so we can interact with computer using our hand gesture instead using a mouse.

In order to effectively control end effector of a robotic manipulator, one needs to solve inverse kinematics of the robot. This paper reports an investigation to solve inverse kinematics of a low cost 6 degrees of freedom (6 DOF) robotic arm. Since this robot provide no feedback signal, we propose to use a simple geometric-based inverse kinematics. Experimental results show the effectiveness of the proposed method, while the accuracy is still acceptable to some extent.

Dynamic stability analysis is one of important issue in electrical power system study. This paper aims to analyze and design the control of power generation operation system in small disturbance events. This condition is affected by changes in the prime mover of mechanical power input in generator system due to power fluctuation in load, so that the system becomes unstable. In the analysis of electrical power distribution, generation unit provides power output based on regulations of fluctuating power. This distribution system that provides continuous data periodically is actually performing a pattern of dynamic time series model. Within the statistical methods analysis, the presentation of load data will be analyzed through clustering method based on the average distribution and peak loads. This kind of pattern description is purposed to enable the control system for anticipating the changes in the load model, where each of load cluster represents one dynamic system model in appropriate operation condition. The solution of dynamic models control systems, performed by Takagi-Sugeno Fuzzy Inference System (TS-FIS) as multiple soft switching controllers and optimal control gain for each dynamic model. Those can be distributed into TS-FIS outputs, to achieve robustness of power generation system that affected by changes in huge variation of load power. In this study, the cluster analysis technique has produced seven data's groups with interval of 18 MVA. By performing Robust-Fuzzy control through TS-FIS as multiple soft switching, can be proved that the power generating performance is better than using Linear Quadratic Regulator (LQR) optimal control, since Robust-Fuzzy control Integral Absolute Error (IAE) is better than LQR optimal control IAE.

Single phase to ground faults are the most frequent problem in the extra high voltage overhead lines, and are temporary in most cases. This type of fault can be quickly eliminated using a single pole reclosure, but secondary arc phenomenon often makes the reclosure fail to work. This study aimed to obtain the characteristics of the secondary arc on the 500 kV transmission lines as well as obtain a solution to minimize the amplitude of secondary arc on both transposed and untransposed lines, so that the reclosure can work properly and the system maintains its stability. The effect of high speed grounding speed and neutral reactor attachment at neutral of shunt reactors on minimizing secondary arc and a possibility to activate shunt reactor only during dead time are analyzed in this study.

This paper presents the forward kinematics analysis for the Mitsubishi Melfa RV-2AJ industrial robot with a five degree of freedom (DOF) revolute joints. The kinematics problem is defined as the transformation from the joint space to the Cartesian space and vice versa. An analytical solution using Denavit-Hartenberg (D-H) representation to describe the position and orientation of the robot end-effector is presented. Several lab experiments to verify the developed kinematics equations have been conducted. In this study, the developed kinematics solutions were found to be accurate (98.68%) compared to the real robot. These findings have important implication for developing dynamic simulation model that can be used to evaluate position and force control algorithm.

This work considers an simulated energy management for energy harvesting sensor nodes. There are four energy management, that is Optimal Offline Policy, Optimal Online Policy, Constant Water Level Policy, Adaptive Energy WF Policy, and Time-Adaptive Energy WF Policy. Energy harvest source that used in this paper is the sun energy. Optimal energy management is energy management that is able to keep maintaining the availability of energy in each time slot and generates optimal throughput. Work scenario for sensor nodes in this simulation is as wireless nodes. The results are extended to include models where differences in propagation paths cause multipath components of transmitted signal arrives at receiver via different propagation paths and different times. Difference in arrival times at receiver causes received signal interference occurs, which would give rise to phenomenon of fluctuations in amplitude and false of received signal, and raises fundamental phenomenon called Fading. Fluctuations in signal amplitude that occurs is random and can not be determined in advance, and when are incurred.

This paper proposes an approach for optimal power flow with incorporation of preventive and corrective control. The approach is useful for operation planning to guarantee secure operation under both normal and contingency states. Therefore, the approach consists of main problem and sub problem representing normal and contingency states, respectively. In normal state, preventive control is used to secure the system while in contingency state, corrective control is employed to satisfy system constraints. The objective of main problem is to minimize operation cost while the sub problem is aimed to minimize power generation deviation in order to avoid ramp rate violation. The approach uses iterative process involving normal and contingency states. At contingency state, power redispatch is conducted as corrective control to avoid system violation. If power redispatch violates ramp rate of generator unit, the exceeding power will be fed back to normal state to recalculate the generator output in the normal state. This calculation in normal state is called as preventive control. To show the effectiveness of the proposed approach, IEEE 9 bus system and modified Jawa Bali 25 Bus system is used. The result shows that the proposed approach is able to secure the operation under both normal and contingency states.
本文提出了一种结合预防控制和纠正控制的最优潮流求解方法。该方法可用于运行规划，以保证在正常和应急状态下的安全运行。因此，该方法由代表正常状态和偶然性状态的主问题和子问题组成。在正常状态下，采用预防控制来保证系统安全;在应急状态下，采用纠正控制来满足系统约束。主问题的目标是使运行成本最小，子问题的目标是使发电偏差最小，以避免坡道速率违规。该方法使用涉及正常和偶然状态的迭代过程。在应急状态下，电力重新调度作为纠正控制，避免系统违规。如果功率重分配违反发电机组的斜坡速率，则将超出的功率反馈到正常状态，重新计算正常状态下的发电机输出。这种正常状态下的计算称为预防控制。为了验证该方法的有效性，采用了ieee9总线系统和改进的java Bali 25总线系统。结果表明，该方法能够保证系统在正常状态和突发状态下的安全运行。

The previous single element antenna was made of two separated layers, one for the patch antenna (upper) and the other for the feed-line (below), using proximity feed for a thin configuration. In this time, a novel dual feed antenna with a hole-truncated is proposed for the generation of a compact LHCP (Left Handed Circular Polarization) using a compact equilateral triangular-patch antenna, that one of the microstrip-line feeds is longer than the other for introducing a 90° phase delay. The influence of the hole-truncated that embedded on the patch is investigated to make the patch antenna smaller than the previous antenna. The method of moments (IE3D Zeland Software) is used considering a finite ground analysis. The simulation results show that the patch length decreases by 12.65 % (a = 52.80 mm to a = 46.12 mm) with a gain and axial ratio at 2.5025 GHz being 6.82 dBic and 0.66 dB, respectively. The bandwidth of the hole-truncated antenna, by comparison of the previous antenna is smaller.
