Optimization of Ship’s Route Scheduling Using Genetic Algorithm

10.11591/ijeecs.v2.i1.pp180-186
Vivi Nur Wijayaningrum , Wayan Firdaus Mahmudy
Route scheduling is a quite complicated process because it involves some determinant factors. Several methods have been used to help resolve the NP-hard problems. This research uses genetic algorithm to assist in optimizing ship scheduling, that where there are several ports to be visited by some ships. The goal is to divide the ship to go to a specific port so that each port is only visited by one ship to minimize the total distance of all ships. The computational experiment produces optimal parameters such as the number of popsize is 30, the number of generations is 100, crossover rate value is 0.3 and mutation rate values is 0.7. The final results is an optimal ship route by minimizing the distance of each ship.

10.11591/ijeecs.v2.i1.pp1-10
Sina Khajeh Ahmad Attari , Mohammad Bakhshipour , Mahmoudreza Shakarami , Farhad Namdari
This paper proposed a novel technique based on teaching-learning-based optimization (TLBO) algorithm in order to find optimal placement of reclosers in the distribution networks which is applied to improve reliability. Reclosers use to eliminate transient faults, faults isolation, network management and enhance reliability to reduce customer outages. According to recloser role in network reliability, the cost for the installation and maintenance must be sustained by distribution companies. Therefore, selecting sufficient number and suitable location for reclosers are important issue. In this paper, the proposed objective function for optimal recloser number and placement has been formulated to improve three reliability indices which consists of three terms; i.e. System Average Interruption Frequency Index (SAIFI), System Average Interruption Duration Index (SAIDI) and Average Energy Not Supplied (AENS). Besides the load model effectiveness has been considered to the simulation. To verify the efficiency of proposed method, it has been conducted to IEEE 69-bus radial distribution system. The obtained simulation results demonstrate the reliability improvement.

Ema Kurnia , I Nengah Surati Jaya , Widi Atmaka
 The earth’s average temperature has been a big issue on the global warming. The warming of the earth is largely the results of emission of carbon dioxide and other greenhouse gasses (GHG) from human activities. As a hinterland of the Capital City, in the last two decades, Bogor is also getting warmer in comparison with the previous decades. This paper presents how the land surface temperature (LST) had been estimated using Split-Window (SW) algorithm and how its spatial distribution in Bogor was computed. The spectral radiance of Landsat-8 TIR bands 10 and 11, the emissivity values, and water vapor used as the input on SW Algorithm. The study revealed that the temperature within the built-up area, have warmer temperature than their surrounding ranging from 400C to 450C of 3,403.9 ha. The use of SW algorithm is quite reliable and accurate to estimate the LST derived from Landsat-8 having a mean deviation of only 2.7%, less than standard acceptable of 10%.

Attack Detection in a Rule-Based System Using Fuzzy Spiking Neural P System

10.11591/ijict.v5i1.pp11-20
Kazeem Idowu Rufai
The virtual area of communication known as cyber space brought about by the debut of the internet has enabled some cyber crimes – ‘Intrusion’ inclusive. So, efforts are being geared towards ensuring that reliable and efficient Intrusion Detection Systems (IDSs) are developed to curtail this menace. However, Spiking Neural P (SN P) systems have been established as a class of distributed parallel computing models. So, in this paper, a novel network intrusion prediction model based on trapezoidal Fuzzy Reasoning Spiking Neural P (tFRSN P) system, is implemented for the very first time for the detection of intrusion. tFRSN P system is an extension of SN P system. It has a graphical modeling advantage which makes it well suited for fuzzy reasoning as well as fuzzy knowledge representation using If-Then rules. The dynamic firing power of neurons is harnessed in a simple parallel matrix-based fuzzy reasoning format to generate inferences. To establish the effectiveness of this approach especially in the area of speed of parallel reasoning and the handling of uncertainties, detection of Brute Force Attack (BFA) is used for demonstration. From the crisp results (0.0431, 0.0414, 0.4453, 0.1703 and 0.0414) obtained, it shows that the parallel processing capability of tFRSN P system could be used to rapidly reason and analyze the severity (possibility of an attack) from any network data.

This paper analyzes the impact of gas drainage borehole drilling rod vibration phenomena stability.Taking 100m hole depth in underground coal mine as an example, the dynamic simulation analysis of the underground gas drainage drilling rod was carried out by using the ANSYS finite element dynamic analysis module LS-DYNA method.According to the collision course between the drill pipe and the coal hole wall, the Lagrange algorithm is introduced to analyze the stress change of drill pipe in the collision course of 98mm, 108mm, 118mm and 128mm. The failure mechanism of drill pipe fatigue fracture and hole wall instability caused by the collision between drill pipe and coal hole is analyzed. The results show that the stress caused by the impact of drilling speed, drilling pressure and coal hole diameter is larger than that caused by the collision between drill pipe and coal wall.

Synchronverter Control for Parallel Operation of Cascaded H-Bridge Inverter

10.11591/ijeecs.v2.i1.pp107-114
Amar Hamza , Sara Altahir , Xiangwu Yan
A 21-levels cascaded H-bridge multilevel inverter topology based on three-phase voltage source inverter has been proposed as a superior replacement for conventional two-level in high voltage applications. In this work we have presented the usage of the new technique called virtual synchronous generator based synchronverter model to operate the multilevel inverter as synchronous generator, and to share active and reactive power automatically in case of parallel operated inverters of the same type. Carrier-based PWM is used to control each phase leg of the cascaded H-bridge multilevel inverter. This carrier-based PWM scheme is derived from the carrier phase disposition pulse width modulation strategy. By aid of MATLAB/Simulink package a simulation experiment is established to verify the performance of the proposed technique.

Half Iris Matching Based on RED Algorithm

10.11591/ijict.v5i1.pp21-27
Akeel Ali Al-Hillali , Safaa S Omran
Iris recognition is one of the most accurate identification method and it is powerful for secure of information and identification between users. The Ridge Energy Direction (RED) algorithm is the most accurate and fast approach for iris recognition.  The RED algorithm reduces the effects of illumination, since only direction is used. The RED algorithm is applied after a normalization process consisting on two filter types (horizontal and vertical). This paper extends this algorithm by considering the lower portion of the iris because this portion is affected with less noise. We used different size of RED filter on Iris in order to compare the accuracy and time between them. We found that the higher filter size gives more accuracy but more processing time

Optimal Selection of UPFC Parameters and Input Controlling Signal for Damping Power System Oscillations

10.11591/ijeecs.v2.i1.pp61-68
Moslem Salehi , Ali Akbar Motie Birjandi
 Unified power flow controller (UPFC), as one of the most important FACTS devices, can be used to increase the damping of power system oscillation. The effect rate of this controller on increasing oscillation damping depends on the appropriate selection of input controlling signal, optimal selection of UPFC controlling parameters, and its proper position in power system. In this paper, the capability of different UPFC inputs is studied by utilizing singular value decomposition (SVD) method and the best UPFC input controlling signal is selected. Supplementary control parameters are also optimally selected by PSO algorithm. This method's accuracy is simulated on a single-machine system connected to infinite bus.

Energy Efficiency in Cognitive Radio Network: Green Technology Towards Next Generation Networks

10.11591/ijict.v5i1.pp45-50
Seetaiah Kilaru , Adithya gali
Energy efficiency of mobile network is always a challenging task. From the past decade, it is observable that the users who are using multimedia services are increasing in rapid way. These multimedia applications require higher data rates. High data rates will consume more energy of mobile network, which results poor energy efficiency. To meet higher data rates and to achieve energy efficiency, Cognitive Mobile Network with small cell model was explained in this paper. Dynamics of the power grid also have significant impact on mobile networks, hence smart grid implementation was proposed instead of traditional power grid. Most of the existed studies on cognitive mobile network focussed on spectrum sensing only. This paper focussed on cognitive radio network implementation by considering spectrum sensing and smart grid environment. An iterative algorithm was proposed to attain equillibrium condition to the problem. Interference management and energy efficient power allocation were achieved with the introduction of smart grid. Simulation results proved that optimum power allocation and energy efficiency are possible with the introduction of smart grid in cognitive network.

10.11591/ijeecs.v2.i1.pp151-160
N. Satish Kumar , Shobha G
This paper presented an approach to building background model for moving object detection using unsupervised Artificial Neural Network (ANN) without any prior knowledge about foreground objects. First, using Local Binary Pattern (LBP) which is texture feature, builds a statistical Background Model using ANN, then, comparing the behavior of next incoming frame with model and decide each pixel whether is deviating from a model or not. And based on if method detects foreground objects then background model is updated to make this model adaptive. Also, spatial-temporal information has been exploited in this method to suppress sudden illumination variation and to suppress false foreground pixels.  It was demonstrated and proved, by qualitative and quantitative metrics that the newly presented approach is adaptive, generic and can address all issues and challenges for background subtraction. To evaluate the performance of the presented approach this paper compared with recent approaches by using standard metrics and proved that presented method outperforms many existing recent approaches.
