Abstract

This paper presents a moving vehicle detection and tracking system, which comprising of Horizontal Edges method and Local AutoCorrelation. Horizontal Edges characteristic can be strengthened and the influence of weather condition is reduced by using Local AutoCorrelation, so the detection rate of extracting and tracking moving vehicles with horizontal edge can be raised. Local AutoCorrelation images are generated for vehicle detection and based on Horizontal Edges method. The distance of the gravity center of Horizontal Edges is used to track vehicles in traffic video. We verify the system using a variety of weather (in fog, car shadow existence, morning and evening) traffic video. Experimental results have shown that the high detection rate of moving vehicles be obtained by using the proposed method. DOI: http://dx.doi.org/10.11591/telkomnika.v11i11.3485

Abstract

Quantum-dot Cellular Automata (QCA) is one of the most important computing technologies for the future and will be the alternative candidate for current CMOS technology. QCA is attracting a lot of researchers due to many features such as high speed, small size, and low power consumption. QCA has two main building blocks (majority gate and inverter) used for design any Boolean function. QCA also has an inherent capability that used to design many important gates such as XOR and Multiplexer in optimal form without following any Boolean function. This paper presents a novel design 2:1 QCA-Multiplexer in two forms. The proposed design is very simple, highly efficient and can be used to produce many logical functions. The proposed design output comes from the inherent capabilities of quantum technology. New 4:1 QCA-Multiplexer has been built using the proposed structure. The output waveforms showed the wonderful performance of the proposed design in terms of the number of cells, area, and latency.

Abstract

Wireless sensor networks (WSNs) have been widely researched by countries and institutes. The limited node energy has already become a constraint of large-scale applications. Seeking the energy-balance features at sensor nodes to prolong the network lifetime, a multi-track mobile data collecting mechanism (MTMDC) was proposed in this paper. The MTMDC mechanism was composed of three major phases: the Nodes Estimation Phase, the Energy Estimation Phase and the Multi-track Energy-balance Phase. Based on the three phases, a data collection path for mobile data collector or mobile sink (MS) was built to balance the energy consume of the sensor nodes. Theoretical analysis and performance simulations indicated that the proposed MTMDC mechanism has prominent features compared with the existing approaches in terms of the energy-balance performance and network lifetime. DOI : http://dx.doi.org/10.11591/telkomnika.v12i2.3736

Abstract

Micromachined gyroscope always contains two groups of capacitors, one is the driving capacitor, which is used to drive the micromachined gyroscope, to make sure the gyroscope could oscillate along the driving direction. The other is so called the sensing capacitor, which used to detect the displacement along the sensing direction, in order to detect the input angle velocity. Since there are some imperfections during the machining process, the static value of the driving capacitor and sensing capacitor always have some variations. These variations would cause some bad effects in the integrated circuit. In this paper, the variations of driving capacitor and sensing capacitor are analyzed based on the principle of integrated circuit. It is shown that the effect caused by driving capacitor variation would be cancelled in the signal processing, but the driving capacitor variation could cause a DC error signal at the output node of the first LPF in the integrated circuit. This DC error would distort the desired signal at the output node of the amplitude amplifier. So that a DC error self-correcting circuit is designed, both the simulation results and the testing results show that DC error could be self-corrected by this additional circuit. DOI: http://dx.doi.org/10.11591/telkomnika.v11i5.2513

Abstract

Tidal power can play a vital role in integrating as new source of renewable energy to the off-grid power connection in isolated areas, namely Sandwip, in Bangladesh. It can reduce the present energy crisis and improve the social, environmental and economical perspective of Bangladesh. Tidal energy is becoming popular around the world due to its own facilities. The development of any country largely depends on energy sector improvement. Lack of energy sector is because hampering of progress of any country development and energy sector will be stable by only depend on sustainable energy sources. Renewable energy is the only sustainable solution of secure energy which is environmental friendly. Bangladesh has a huge potential of tidal power at different locations but effective measure on this issue have not been considered sincerely. This paper summarizes the current energy scenario and Bangladesh can produce power approximately 53.19MW across the country to reduce the growing energy demand utilizing tidal energy as well as it is shown that Sandwip has high potential of producing tidal power which is approximately 16.49MW by investing only US $10.37 millions. Besides this, cost management for tidal power plant also has been discussed.

Abstract

Water quality monitoring is always the prior element to ensure the drinking water is safe to be consumed. A lot of researches have been carried out over the past decades to design and develop a robust and cost-effective water monitoring system. The conventional water monitoring techniques were based on laboratory instruments which is time-consuming and laborious. Furthermore, it is not suitable when the water sampling point is far from the commercial laboratory centres. These limitations were then been solved by the developments of portable testing kits and microwave technique. The microwave techniques such as spectroscopy techniques and microwave sensor approach have improved the water quality monitoring experience which is convenient without sacrificing the measurement accuracy and sensitivity. Its portability enables the on-site measurement at rural areas and thus reduce the transportation and manpower cost. This paper intends to review the water contaminant detection techniques which include standardized drinking water parameter testing and microwave-based in terms of physical, chemical and microbiological parameters. Furthermore, this review also emphasizes the current trend of the water quality testing method in microwave technique. At the end of this paper, a significant advantages and drawbacks of the techniques are summarized, and recommendations are provided for future development in the water quality monitoring.

Abstract

Auction models and protocols are found efficient in managing resources allocation, which are a key technology in grid computing system. In this paper, a new multi-attribute multi-round reverse auction is proposed, and related reverse auction based protocols are designed. The resource user’s satisfaction degree is introduced into the traditional grid resource allocation problem to help the grid resource broker make multi-attribute decisions with incomplete information. Numerical simulating experiments show that our model and protocols can satisfy the resource user’s quality demand on multiple attributes, and achieve high efficiency in user utility. The results also illustrate that the on-line multi-attribute algorithm in ONMRA protocol has better performance in an on-line setting for grid allocation. DOI: http://dx.doi.org/10.11591/telkomnika.v11i10.3347

Abstract

Hyperspectral unmixing (HU) is an important technique for remotely sensed hyperspectral data exploitation. Hyperspectral unmixing is required to get an accurate estimation due to low spatial resolution of hyperspectral cameras, microscopic material mixing, and multiple scattering that cause spectra measured by hyperspectral cameras are mixtures of spectra of materials in a scene. It is a process of estimating constituent endmembers and their fractional abundances present at each pixel in hyperspectral image. Researchers have devised and investigated many models searching for robust, stable, tractable and accurate unmixing algorithm. Such algorithm are highly desirable to avoid propagation of errors within the process. This paper presents the comparison of hyperspectral unmixing method by using different kind of algorithms. These algorithms are named VCA, NFINDR, SISAL, and CoNMF. The performance of unmixing process is evaluated by calculating the SAD (spectral angle distance) for each endmembers by using same input of hyperspectral data for different algorithm.

Abstract

The main objective of this paper is to present a new numerical method with utilization of fuzzy transform in order to solve various engineering problems that represented by hyperbolic Goursat partial differentical equation (PDE). The application of differential equations are widely used for modelling physical phenomena. There are many complicated and dynamic physical problems involved in developing a differential equation with high accuracy. Some problems requires a complex and time consuming algorithms. Therefore, the application of fuzzy mathematics seems to be appropriate for solving differential equations due to the transformation of differential equations to the algebraic equation which is solvable. Furthermore, development of a numerical method for solving hyperbolic Goursat PDE is presented in this paper. The method are supported by numerical experiment and computation using MATLAB. This will provide a clear picture to the researcher to understand the utilization of fuzzy transform to the hyperbolic Goursat PDE.
