Abstract

Boost half bridge DC-DC converters in the combination of an input-series and output-series (ISOS) connected configuration with a stable control strategy has been investigated in this paper. A stable control strategy comprises of two loops that are current loop and voltage loop. The reference to the current loop has been chosen from the input side of the DC-DC converter. The reference to the voltage loop has been selected from the output side of the DC-DC converter. Such a reference makes the circuit configuration simple, easy and eventually results in reduced cost. The control strategy for input-series output-series (ISOS) configuration of DC-DC converters is proposed to achieve equal input voltage sharing (IVS) as well output voltage sharing (OVS). Furthermore, in this paper, the performance of the stable control strategy for input-series output-series (ISOS) boost half bridge DC-DC converter has been observed not only for the fixed but also for the varying and continuously varying load. The proposed Stable control scheme has been developed by modeling it on MATLAB using Simulink and Simpower toolboxes. The operation of the proposed stable control strategy has been found to be satisfactory.DOI : http://dx.doi.org/10.11591/telkomnika.v12i1.3098

Abstract

The main goal is to simulate different configurations of street lighting system using DIALux and optimize the energy consumption. Data of the existing road in the United Arab Emirates is considered for simulation. Simulation results are validated by building a hardware model. This is accomplished by using LED modules instead of traditional HPS bulbs which is connected to an Arduino to control different sensors. Photo resistors are used to automatically switch the lights ON or OFF depending on the light intensity. Ultrasonic sensors are used to detect motion of cars and pedestrians in order to switch 50% of the lights off if no motion is detected. The recorded data is monitored by a Raspberry Pi which acting as a monitoring device. Practical measurements were conducted at different points on the road selected and are compared with the simulation results.The main goal is to simulate different configurations of street lighting system using DIALux and optimize the energy consumption.

Abstract

Currently, there are a large number of heterogeneous platforms. The standards of Web Services in different platforms are different and complex. Therefore, security interaction of Web services based on heterogeneous platform has become increasingly prominent. In order to realize security interaction of heterogeneous platforms, a security interactive model of Web Service based on WebSphere and .NET is proposed in this paper. The model adopts an approach based on predicate logic to integrate the security policies of heterogeneous platforms and uses the integrated policy to sign the SOAP message. The experimental results show that the model can ensure the safety of SOAP message transmission and realize the security session between these two heterogeneous platforms. DOI : http://dx.doi.org/10.11591/telkomnika.v12i4.4734

Abstract

Software Defined Radio (SDR) is a new technology used to implement different wireless communication standard for mobile communication. The Intermediate Frequency (IF) block is the most demanding block in software defined radio. The most important task in intermediate processing block is digital filtering which is carried out by Finite Impulse Response (FIR) filter. One of the major techniques for the calculation of inner product is Distributed Arithmetic (DA) based FIR filter which uses Look Up Table (LUT) to eliminate the need of multiplier. The efficiency of the DA filter is affected with the increasing number of address line and also due to its serial operation. To overcome this problem parallel and pipeline based DA filter using Offset Binary Coding (OBC) for Two Bit At A Time (2-BAAT) is proposed. Our proposed method achieves less area, low power consumption and nominal delay for SDR application.

Abstract

We propose, in this paper, a new method for Content Based Image Retrieval (CBIR) by exploiting the digital image content. Our method is based on the representation of the digital image content by a characteristics vector of the indexed image. Indeed, we have exploited the image texture to extract its characteristics and for constructing a new descriptor vector by combining the Bidimensional High Resolution Spectral Analysis 2-D ESPRIT (Estimation of Signal Parameters via Rotationnal Invariance Techniques) method and Gabor filter. To evaluate the performance, we have tested our approach on Brodatz image database. The results show that the representation of the digital image content appears significant in research of imaging information.

Abstract

Dual-wavelength dissipation soliton (DS) in the all-normal-dispersion ytterbium-doped fiber laser (YDFL) is reported. Using a phase-shift long period fiber grating (PS-LPFG) as an all-fiber format spectral filter in the laser cavity, self-starting dual-wavelength pulses are obtained by nonlinear polarization evolution (NPE). The mode-locking mechanism of the ANDi cavity with different central wavelengths has analyzed. Experimental results show that the NPE together with the PS-LPFG play key roles in the generation of the dual-wavelength, meanwhile, a switchable dual-wavelength mode-locked fiber laser can achieve through change the polarization of the cavity. DOI: http://dx.doi.org/10.11591/telkomnika.v11i10.2961

Abstract

RTS Game is one of the popular genre in PC gaming, which has been played by various type of players frequently. In RTS game, NPC Defense Building (Tower) has attacking behavior to the closest enemy without considering certain enemy parameters. This causes the NPC Tower to be more predictable by the opponent and easily defeated if NPC attacked by enemies in the group. Thus, this research simulates NPC Tower using Hierarchical Finite State Machine (HFSM) method compared with Finite State Machine (FSM). In this study, NPC Tower detects enemies by seeing at four parameters namely NPC Tower Health, Enemy's Health, Enemy Type, and Tower Distance to enemies. NPC Tower will attack the most dangerous enemy according to the ‘Degree of Danger’ parameter. Then use the decision-making logic of the rule-based system. The output of NPC Tower are three type of behaviors namely Aggressive Attacking, Regular Attacking, and Attack with Special Skill. From the test results of 3 NPC Tower, Kamandaka NPC Tower with HFSM method is winning 8.92% compare to Kamandaka Tower with FSM method. For Gayatri Tower NPC obtained equal results using both HFSM and FSM. Meanwhile, Adikara NPC with HFSM method is 4.62% superior to Adikara Tower with FSM method.
