Abstract

Although many methods for optimizing DGplacement and its size in a network with the target of reducingsystem power losses and voltage profile have already beencommended, they still lack from several weaknesses. As a resultmuch can be done about to happen with new algorithms. Theproposed algorithms commonly have stressed their formulationson real power losses only and ignored the reactive power losses.Power systems reactive power injection plays an important rolein voltage stability control, thus the reactive power losses need tobe incorporated in optimizing DG allocation considering theirvoltage profile improvement. Whereas Particle SwarmOptimization (PSO) approach was proposed for finding theoptimal size of DG. This study work intended to apply both realand reactive power flow, power loss sensitivity factors and PSOmethod in finding the candidate buses for DG placement and itssize on Bali’s 150 kV transmission networks. The experimentalresults show that the proposed algorithm is indeed capable ofobtaining a good quality solution efficiently

Abstract

DVC has the characteristics of lighter encoder performance by transferring the efficiency of the field of motion to the decoder. The characteristics of DVC are similar to FRUC which is a technique to improve the quality of video display from the decoder side by inserting interpolated frames. In this study, multi-resolution bilateral motion estimation based on pyramid wavelets is proposed by comparing the order of wavelets contained in the daubechies wavelet. The parameters compared in this study are PSNR and the computational complexity of the proposed method to improve the quality of the video reconstruction from the decoder side. This study shows that the use of the daubechies wavelet order in the proposed method can obtain sufficient category of PSNR values of db6 with a value of 27.37 dB for video images with moving background characteristics and moving objects, good categories of db7 and db10 with a value of 34.8 dB and 32.06 dB for video images with fixed background characteristics and moving objects, and video images with moving background characteristics and fixed objects. The selection of the wavelet order on the daubechies wavelet can be adjusted to the characteristics of the video image that will be used.

Abstract

Abstract— The exact estimation of the number of colonies or Colony Forming Units (CFUs) is frequently used in microbiology research, particularly in the field of bacteria. The number of colonies that develop per gram or milliliter of sample is estimated by multiplying the number of plates, the dilution factor, and the volume used [1]. Counting the number of bacterial colonies can be used to determine a bacterium's growth rate. The cup count method is commonly used to accomplish this manually. An instrument called a colony counter can help with colony counting utilizing the cup count method. This technology works by using a pen connected to a counter to mark the colonies that have been counted. However, because the colony size is tiny and the number of colonies counted is huge, this can lead to inaccuracies, and the same difficulties can happen with manual colony computations. Digital image processing technology has been extensively developed for use in a variety of fields. Researchers had previously undertaken a similar study that attempted to count bacterial colonies and had a 94 percent accuracy rate, but some colonies were not spotted because they were filtered during preprocessing, so they looked into it further. Keywords—Bacteria Colony, Image Processing, Preprocessing,

Abstract

Multilevel inverter (MLI) is one type of inverter that has a multilevel output voltage. Although its better than conventional inverters, the MLIs operating at low frequency still contains low-order harmonics at the output voltage and current which have a negative impact on electrical system. To overcome these problems, Many researchers have developed various control and modulation techniques on inverters to reduce harmonics and minimize switching losses with the aim of optimizing inverter’s efficiency. Selective harmonic elimination pulse-width modulation (SHEPWM) is the most optimal control of all methods that have been developed to remove low-order harmonics from the inverter output voltage. However, there are challenges in the MLIs analysis process using SHEPWM because solving these equations is difficult. Bio-inspired intelligent algorithms (BIAs) is used to solve this problem. This paper describes in full a review of various studies that have been carried out previously related to the operating principle of nine types of BIA and their application in reducing harmonics. The conclusions has been made on the basis of information extracted from the literatures. All important information in this paper regarding harmonic reduction in MLI will help future research to design efficient power conversion systems. Keywords— Bio-inspired algorithm, harmonics, multilevel inverter, optimization, selective harmonic elimination.
