Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control Evaluation of load balancing approaches for Erlang concurrent application in cloud systems Subject The topic of the resource Cloud virtualization, Erlang distribution function, Load balancing, Queueing network analysis, Simulation Description An account of the resource Cloud system accommodates the computing environment including PaaS (platform as a service), SaaS (software as a service), and IaaS (infrastructure as service) that enables the services of cloud systems. Cloud system allows multiple users to employ computing services through browsers, which reflects an alternative service model that alters the local computing workload to a distant site. Cloud virtualization is another characteristic of the clouds that deliver virtual computing services and imitate the functionality of physical computing resources. It refers to an elastic load balancing management that provides the flexible model of on-demand services. The virtualization allows organizations to improve high levels of reliability, accessibility, and scalability by having a capability to execute applications on multiple resources simultaneously. In this paper we use a queuing model to consider a flexible load balancing and evaluate performance metrics such as mean queue length, throughput, mean waiting time, utilization, and mean traversal time. The model is aware of the arrival of concurrent applications with an Erlang distribution. Simulation results regarding performance metrics are investigated. Results point out that in Cloud systems both the fairness and load balancing are to be significantly considered.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control SVC device optimal location for voltage stability enhancement based on a combined particle swarm optimization-continuation power flow technique Subject The topic of the resource FACTS devices, Optimal location, PSO-CPF technique, Static var compensator, Voltage stability Description An account of the resource The increased power system loading combined with the worldwide power industry deregulation requires more reliable and efficient control of the power flow and network stability. Flexible AC transmission systems (FACTS) devices give new opportunities for controlling power and enhancing the usable capacity of the existing transmission lines. This paper presents a combined application of the particle swarm optimization (PSO) and the continuation power flow (CPF) technique to determine the optimal placement of static var compensator (SVC) in order to achieve the static voltage stability margin. The PSO objective function to be maximized is the loading factor to modify the load powers. In this scope, two SVC constraints are considered: the reference voltage in the first case and the total reactance and SVC reactive power in the second case. To test the performance of the proposed method, several simulations were performed on IEEE 30-Bus test systems. The results obtained show the effectiveness of the proposed method to find the optimal placement of the static var compensator and the improvement of the voltage stability.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control The usage of thermoelectric generator as a renewable energy source Subject The topic of the resource Heatsinks, Peltier, Renewable energy, TEG, Thermoelectric generator power plant Description An account of the resource Currently thermoelectric generators (TEG) are widely used in biomedical, military and space satellite power applications. TEG of high power plants are mostly used in automobile and industrial engines. This paper discusses TEG as a renewable energy source. Here the TEG in the application is used in the thermoelectric generator power plant. The working principle of this thermoelectric generator is on the heat side of the TEG peltier which is coated in metal in the form of aluminum, which is heated by a heater. And the cold side of the TEG Peltier is placed on the heat sink (as a heat dissipation metal). Heatsinks are submerged in water which are submerged about half or more. If the temperature of the metal being heated and the temperature of heat dissipation metal have a certain difference, then the temperature difference causes TEG to start working. The greater the temperature difference, the greater the electrical energy produced will be. However, if the temperature difference is too large it will damage the bismuth semiconductor material used. After TEG starts working it will produce voltage and current.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control GWO-based estimation of input-output parameters of thermal power plants Subject The topic of the resource Fuel cost curve, Grey wolf optimizer, Input-output parameters, Parameter estimation Description An account of the resource The fuel cost curve of thermal generators was very important in the calculation of economic dispatch and optimal power flow. Temperature and aging could make changes to fuel cost curve so curve estimation need to be done periodically. The accuracy of the curve parameters estimation strongly affected the calculation of the dispatch. This paper aims to estimate the fuel cost curve parameters by using the grey wolf optimizer method. The problem of curve parameter estimation was made as an optimization problem. The objective function to be minimized was the total number of absolute error or the difference between the actual value and the estimated value of the fuel cost function. The estimated values of parameter that produce the smallest total absolute error were the values of final solution. The simulation results showed that parameter estimation using gray wolf optimizer method further minimized the value of objective function. By using three models of fuel cost curve and given test data, parameter estimation using grey wolf optimizer method produced the better estimation results than those estimation results obtained using least square error, particle swarm optimization, genetic algorithm , artificial bee colony and cuckoo search methods.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control A principal component analysis-based feature dimensionality reduction scheme for content-based image retrieval system Subject The topic of the resource Content-based image retrieval system, Feature dimensionality reduction, Low-level visual feature, Principal component analysis Description An account of the resource In content-based image retrieval (CBIR) system, one approach of image representation is to employ combination of low-level visual features cascaded together into a flat vector. While this presents more descriptive information, it however poses serious challenges in terms of high dimensionality and high computational cost of feature extraction algorithms to deployment of CBIR on platforms (devices) with limited computational and storage resources. Hence, in this work a feature dimensionality reduction technique based on principal component analysis (PCA) is implemented. Each image in a database is indexed using 174-dimensional feature vector comprising of 54-dimensional colour moments (CM54), 32-bin HSV-histogram (HIST32), 48-dimensional gabor wavelet (GW48) and 40-dimensional wavelet moments (MW40). The PCA scheme was incorporated into a CBIR system that utilized the entire feature vector space. The k-largest eigenvalues that yielded a not more than 5% degradation in mean precision were retained for dimensionality reduction. Three image databases (DB10, DB20 and DB100) were used for testing The result obtained showed that with 80% reduction in feature dimensions, tolerable loss of 3.45, 4.39 and 7.40% in mean precision value were achieved on DB10, DB20 and DB100.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control End-effector wheeled robotic arm gaming prototype for upper limb coordination control in home-based therapy Subject The topic of the resource Character recognition, Child education, Edutainment, Intelligence, Robotics Description An account of the resource The stroke patient will be having difficulty to control their upper limb, which causes their handling to become weak and unorganized. Conventional therapy designed to retrain the subject ability when it's losses due to stroke. As previous study concern that a subject with strong motivation and concentration of treatment tends to recover better than people who don't follow the program. This research focused on intensifying the training by providing user with wheel robotic arm to train their upper limb. User will be asked to do exercising on moving particular objects to another position repetitively during a specific period. The robot will help the user to assist and relearn their motoric skill and improve muscle strength and coordination. The result of training is quite convincing when the user gives a positive response toward the practice. Around 86 percent of subject likely prefer the proposed system as their home-based rehabilitation system. The Anova testing with alpha 0.05 shows that there is no significant difference between trained subject and untrained subject on operating the wheeled robotic arm. It's mean the proposed system is reliable and user friendly to be used without an assistant so user can have more flexibility and improve their accomplishment on regaining their motoric skills. The future work will focus on stroke patient testing with more challenge and obstacle in enhancing the effectiveness of the stroke rehabilitation system.
