Smoothed particle hydrodynamics (SPH) is meshless-based numerical method to simulate free-surface flow problems. In this paper, water wave impact on a floating object is studied by implementing SPH method. An open-source DualSPHysics code which is developed based on SPH theory is used to simulate three-dimensional (3D) free-surface flow with floating object. Graphical processing units (GPUs) parallel...
This paper describes the use of convolutional neural network(CNN) method to classify various image and photo of Indonesia ancient temple. The method itself implements Deep Learning technique designed for Computer Vision task. The idea behind CNN is image pre-processing through a stack of convolution layers to create many patterns that can be easily recognized. The result shows that the learning model...
Wireless video capsule endoscopes (VCEs) are used to diagnose intestinal abnormalities. By accurate localization of the VCE, proper diagnosis of the lesions are possible. In this letter, we propose path loss degree based weighted centroid localization (WCL) for VCE. The main challenge in path loss based VCE localization is the random deviation in the measured path loss caused by shadowing and multi-path...
The proposed antenna is implemented for three bands operation system modern global system for mobile (GSM), microwave worldwide interoperability (WiMAX), and local area network (WLAN). The designed antenna consisted of a low profile square-ring planar microstrip antenna, with dimensions of 37×37 mm2. The antenna operates at 1.8 GHz, 3.6 GHz, and 5.5 GHz frequencies for GSM, WiMAX and WLAN characteristics...
The equivalent circuit of square-loop-resonator (SLR) bandpass filter (BPF) with cross-shaped I/O coupling is investigated to be analyzed and compared with the 3D electromagnetics (EM) simulator result. The proposed SLR BPF is designed for X-band frequency application with the center frequency of 9GHz and the −3dB fractional bandwidth larger than 3%. The analysis method is carried out by separating...
Under Real-Time Pricing (RTP) the cost per kWh varies with time as a consequence of the changing supply and demand conditions in the market. Customers that are able to shift their electricity consumption patterns can reduce their costs by using their devices when price is low. This requires a smart power outlet that can turn itself on/off based on price, and customer preferences. This paper is about...
This paper proposes a Multi-Agent System (MAS) modeling and control architecture for a solar driven DC microgrid. The microgrid consists of solar system as a source of power, energy storage system, critical and non-critical houses (loads) with their own solar and storage as well. For the proposed MAS an individual house can have the ability to sell extra power to the main solar source. The main solar...
Hybrid amplifier is a promising technology and give a better performance because it can handle network with a high traffic. Hybrid amplifier is used to optimize gain bandwidth of WDM-based system. Optimization of the hybrid amplifier (Raman-EDFA) make gain spectrum being around the same reinforcement intensity by lowering the gain flatness of 4.3 dB to 0.01 dB with an average gain of about 25.7 dB...
In this paper, described depth first search algorithm being implemented on line maze solver robot. Right hand rule will be used to select the turn priority. Some mazes will be used to test the reliability of this depth first search maze solver robot. In the result, the system is able to use depth first search algorithm well. The robot able to finish non-loop maze with 84.97 s average time and with-loop...
Currently, Blackbox records all important information that happens during the accident that is Flight Data Recorder (FDR) and Cockpit Voice Recorder (CVR). The data is for by applying a compression method to make both of them get into transmission with on demand. This way is probably to present the data without has to find the black box. It will make the investigator easier on the evacuation process...
Heart health is one of the parameters of one's health condition. Besides using the ECG machine, heart conditions can be determined through blood pressure measurement. Patient's hypertension requires the continuous blood pressure measurement. In some conditions, the health of patients cannot be directly checked at healthcare center. For this, the mobile blood pressure meter devices can send data in...
To design an automatic controller of a tracking system usually can be built by analyzing response output system. However in many cases especially in complex dynamics system for example quadrotor controller, it is not trivial to end this. Control design for quadrotor can be done by modeling the dynamics system. When dynamics system can be modeled close to real system characteristics, then accurate...
The goal of this paper is to measure the parallel performances using OpenMP for surface gravity waves simulation. Here, the non-hydrostatic model is used to describe the fluid flows. The discretization of pressure, horizontal and vertical velocity are given in staggered grids by Arakawa grids. The numerical simulation of gravity waves with wavelength 100 meters is elaborated. The results are shown...
In this paper, we implement an embedded control system to a four-wheel omniwheel vehicle. PID control is used to stabilize the velocity of each wheel so the vehicle can move steadily. Color markers are used as navigation waypoints and to correct any deviation on the vehicle movement. The implemented system is capable to reduce the vehicle's movement deviation when move straight from one marker to...
This paper is devoted to investigate the behavior of Newton's method for approximating the epicenter of earthquake. Here, the earthquake in center of Italy 24 August 2016 is considered. The seismic data of Pg waves only is used as preparation data. Here, three scenarios which are depend on the minimum, average and maximum velocity of seismic Pg waves for the numerical simulations are elaborated. The...
To meet the increasing electricity demand in the island of Indonesia, especially in areas that are lack access of electricity, it would be beneficial for these these islands to produce electricity using local potential renewable energy sources. In this study, Papua Province, the eastern region of Indonesia with 28 Districts, where 2,114 villages do not have electricity access was taken as the region...
Ocean wave is one of the potential renewable energy sources that can prospectively be developed into Wave Power Plant. Our study aims to analyze the feasibility of sea wave power plant in the area Sibolga-Tapanuli Tengah which most of the area is ocean and directly adjacent to the Indian Ocean. Water Colum oscillating system (OWC) and Ocean Surface Wave (OSW) are both two methods of converting ocean...
In this research, we proposed the audio watermarking system with adaptive multilevel DWT (discrete wavelet transform) — SVD (singular value decomposition) based on BCH (Bose-Chaudhuri-Hocquenghem) code. The host audio signal is embedded with a watermark signal in the form of an image signal accompanied by several attacks on the watermarking system. The results showed that the perceptual quality of...
Wireless Sensor Network is used in some applications such as environmental monitoring, search and rescue missions, geographic routes and tracking. WSN can be a telemetry solution to ensure that the rescue communication system works properly and effectively. Although localization is not the primary purpose of the Wireless Sensor Network, sensory information is senseless when the location of the observed...
