Salman A. Chowdhury, M. M. Hossain, M. Sayem, Md. Rafiqul Islam Sheikh
In this paper, the performance analyses of Solid State Dye Sensitized Solar Cells (SSDSSCs) are carried out with power grid integration and off-grid operation in the intertropical region being the main focus. It has been observed that electrodes of different compositions such as: TiO2 and ZnO, surface morphology of the thin films used in SSDSSCs, use of different types of dyes as photo sensitizers, use of Nanorods/Nanoparticles as photoanodes — all correspond to different photoelectric conversion efficiencies (PCEs) in SSDSSCs. As the SSDSSCs are free of leakage and corrosion related problems prevalent in conventional liquid-based Dye Sensitized Solar Cells (DSSCs), it has the potential to lower the maintenance cost and improving longevity of a system, so far however SSDSSCs suffer from low PCEs when compared with conventional DSSCs, with a maximum efficiency record of approximately 15 per cent set in 2013 by using solid-state mesoscopic TiO2 solar cells sensitized with lead iodide perovskite (CH3NH3PM3) pigments[1–4], in early 2014 which was further lifted to 16.7 per cent[26]. Careful selection of highly photosensitive dye in conjunction with proper nanotube photonic crystals can optimize the efficiency of SSDSSCs for the intertropicsl region.
本文对固态染料敏化太阳能电池(SSDSSCs)的性能进行了分析,重点研究了其在热带地区的并网和离网运行。研究发现,不同组成的电极(如TiO2和ZnO)、SSDSSCs薄膜的表面形貌、使用不同类型的染料作为光敏剂、使用纳米棒/纳米颗粒作为光阳极,都对应着SSDSSCs中不同的光电转换效率(pce)。由于SSDSSCs不存在传统液体基染料敏化太阳能电池(DSSCs)中普遍存在的泄漏和腐蚀相关问题,因此它具有降低维护成本和延长系统寿命的潜力,然而到目前为止,SSDSSCs与传统DSSCs相比,其pce较低。2013年,使用碘化铅钙钛矿(CH3NH3PM3)颜料敏化的固态介孔TiO2太阳能电池创造了约15%的最高效率记录[1-4],2014年初进一步提高到16.7%[26]。精心选择高光敏染料,结合适当的纳米管光子晶体,可以优化SSDSSCs在热带地区的效率。

A. Tariq, Ruhul Amin, Md. Nazrul Islam Mondal, Md. Ali Hossain
Modern world has become more dependent on electronics and hence speed is a major factor in the field of their functionalities. Modern CPUs work lot faster and efficiently than older versions. Still humans require more and more time efficiency in their daily computational works. In this paper, the main focus is on the increase of time efficiency in computing. Hence this paper shows a time performance comparison between FPGA and CPU implementation. In this regard, Booth's multiplication algorithm has been implemented on both CPU and FPGA to compare the running time. The FPGA implementation is found out to be around 9 times faster than that of a modern CPU implementation.

Gaussian mixture based semi supervised boosting for imbalanced data classification 基于高斯混合的半监督增强非平衡数据分类
Mahit Kumar Paul, B. Pal
Semi supervised approaches are practical in problem domain where pattern clustering is supposed to provide good classification. Gaussian Mixture Model (GMM) can approximate arbitrary probability distribution, thus is considered as a dominant tool for classification in such domains. This paper appraises the functioning for GMM as it is applied to imbalanced datasets which consists of uneven distribution of samples from all the classes. Later, an ensemble approach is presented to boost the GMMs in a semi supervised manner via Adaptive Boosting technique. Experiment on benchmark imbalanced datasets with different imbalance ratio has been carried out. Empirical result demonstrates the efficacy of the proposed Boosted GMM classifier compared to baseline approaches like K-means and GMM.
半监督方法在模式聚类需要提供良好分类的问题领域是实用的。高斯混合模型(GMM)可以近似任意概率分布,因此被认为是这类领域分类的主要工具。本文评估了GMM的功能,因为它适用于由所有类别的样本分布不均匀组成的不平衡数据集。在此基础上,提出了一种集成方法,利用自适应增强技术以半监督的方式增强gmm。在不同不平衡率的基准不平衡数据集上进行了实验。与K-means和GMM等基线方法相比,经验结果证明了所提出的boosting GMM分类器的有效性。

Robust beamforming synthesis technique for low side lobe level using taylor excited antenna array 基于泰勒激励天线阵列的低旁瓣级鲁棒波束形成合成技术
M. A. Sarker, M. S. Hossain, M. S. Masud
Antenna array is one of the most useable technologies in present day communication system. There are many applications like biomedical imaging, military communication and radar system where low side lobe level is an essential feature of array processor. There is a trade-off between side lobe level (SLL) and the directivity of the array. Designing an antenna array system with optimum trade-off between SLL and directivity has become a crucial problem. To suppress high SLL of output beam pattern and signal direction mismatches, some notable optimization techniques have been developed. Amplitude weighting of array elements is a well known approach for SLL control. In real-time implementation of antenna array system, the main beam may not be in the assumed direction and the actual signal is treated as an interference signal which is undesirable. Hence the robustness of an array processor against uncertainties is an important issue. In this paper, a method is proposed to keep the SLL at the desired value as well as makes the array system more applicable for real time implementation considering array uncertainties and imperfections.
天线阵列是当今通信系统中应用最为广泛的技术之一。低旁瓣电平是阵列处理器的一个重要特点,在生物医学成像、军事通信和雷达系统等许多应用中都有应用。在旁瓣电平(SLL)和阵列的方向性之间存在权衡。设计一种能在SLL和指向性之间实现最佳平衡的天线阵列系统已成为关键问题。为了抑制输出波束方向和信号方向不匹配的高SLL,人们开发了一些值得注意的优化技术。阵列元素的振幅加权是一种众所周知的小波散射控制方法。在天线阵列系统的实时实现中,主波束可能不在假设的方向上,实际信号被视为干扰信号,这是不希望出现的情况。因此,阵列处理器对不确定性的鲁棒性是一个重要的问题。在考虑阵列的不确定性和不完备性的情况下,本文提出了一种方法,使阵列系统在保持期望SLL值的同时,更适合于实时实现。

Regenerative braking characteristics of PMDC motor by applying different armature voltage 不同电枢电压对PMDC电机再生制动特性的影响
S. Billah, Kazi Khairul Islam
Energy saving and prolonging mileage are very important for battery-operated electric vehicles (BEV). For saving energy in BEV's the key parts are regenerative braking performances. Permanent magnet DC (PMDC) motor based regenerative braking can be a solution to improve energy saving efficiency in BEV. In this paper, a novel regenerative braking mechanism based on PMDC motor is proposed. Based on proposed method braking can be achieved by applying different armature voltage from a battery bank without using additional converter with complex switching technique, ultra capacitor, or complex winding-changeover. An experimental setup has been used to evaluate the performance of the proposed braking system. Simulated results prove that the proposed regenerative braking technique is feasible and effective. Also this research provides simplest system for regenerative braking using PMDC motor to improve the mileage of electric vehicles.

Performance analysis of acoustic microphone array beamformer in the presence of interfering signal 干扰信号存在下的声传声器阵列波束形成器性能分析
M. Hossein, M. S. Hossain, M. Reza
The acoustic beamformer is an important tool which is used in many environments to focus on a specific sound among many reverberations. This paper presents an acoustic microphone array beamformer in the presence of unwanted signal. Time delay and Frost beamforming techniques are used with microphone array to reduce the noise and cancel the interfering signal respectively. The presented beamformers can be able to increase the system SNR without array mismatch. The performance of the time delay and Frost microphone arrays will degrade in the presence of array imperfections. To improve the system performance a robust algorithm is addressed in this paper. The extensive computer simulation is presented to analyze the performance of the acoustic beamformer with different scenarios.

Improved two-vector direct power control algorithm-based three-phase pulse width modulation rectifier 基于改进的双矢量直接功率控制算法的三相脉宽调制整流器
Likun Liu, W. Xu, Md. Rabiul Islam
Direct power control (DPC) has received a significant amount of research attention because of its benefits such as simplicity, robustness and excellent dynamic response. Conventional switching-table-based single-vector DPC (SV-DPC) presents irregular power ripples and variable switching frequency, due to the use of predefined switching table and hysteresis comparators. To solve these problems, two-vector DPC (TV-DPC) and three-vector DPC (THV-DPC) based three-phase pulse width modulation (PWM) rectifier are proposed. Although the performance of the THV-DPC is better than that of TV-DPC, its algorithm implementation is very complex and time consuming. In this paper, two-three combined vector DPC (TTCV-DPC) algorithm is presented which combines two and three voltage vectors by the help of the new switching table. The proposed algorithm has less complexity than the THV-DPC and better performance than the TV-DPC. Comprehensive simulations demonstrate the proposed method can get lower power ripple and lower grid-side current total harmonic distortion (THD) than that of TV-DPC.
直接功率控制(DPC)以其简单、鲁棒性和良好的动态响应等优点受到了广泛的关注。传统的基于开关表的单矢量DPC (SV-DPC)由于使用了预定义的开关表和迟滞比较器,导致功率纹波不规则,开关频率可变。为了解决这些问题,提出了基于两矢量DPC (TV-DPC)和三矢量DPC (THV-DPC)的三相脉宽调制整流器。虽然THV-DPC的性能优于TV-DPC,但其算法实现非常复杂且耗时。本文提出了一种利用新型开关表将两个电压矢量和三个电压矢量组合在一起的二-三组合矢量DPC (TTCV-DPC)算法。该算法的复杂度低于THV-DPC,性能优于TV-DPC。综合仿真结果表明,与TV-DPC相比,该方法具有较低的功率纹波和较低的电网侧电流总谐波失真(THD)。

Md. Faruk Hossain, Tanzila Noushin
The aim of this paper is to analyze the effect of adding graphene layer on the porous silicon waveguide sensor.

A solution for the conventional wind farms by using semi-converter based PMSG with a higher capacity 采用基于半变流器的高容量PMSG解决传统风电场的问题
Z. Tasneem, M. Sheikh, M. Islam
The performance of induction generator (IG) based wind farms is not satisfactory these days. The existing IG based farms create a huge problem especially in case of expanding the capacity of the wind farm. This paper introduces a new solution for the problem. It suggests that the introduction of permanent magnet synchronous generator (PMSG) with IG, not only expands the capacity of the wind farm, but also it produces a stable output. A practical case considering Synchronous Generator (SG) in combination with a wind farm having both IG and PMSG has been used. The proposed PMSG has been equipped with the full-rated power converters. The results prove the effectiveness of the proposed model. Simulations have been done by using the engineering software PSCAD/EMTDC. Real wind speed data have been considered for this study.

Real time Google map and Arduino based vehicle tracking system 实时谷歌地图和基于Arduino的车辆跟踪系统
Md Marufi Rahman, J. R. Mou, Kusum Tara, M. I. Sarkar
A vehicle tracking system is very useful for tracking the movement of a vehicle from any location at any time. In this work, real time Google map and Arduino based vehicle tracking system is implemented with Global Positioning System (GPS) and Global system for mobile communication (GSM) technology. GPS module provides geographic coordinates at regular time intervals. Then the GSM module transmits the location of vehicle to cell phone of owner/user in terms of latitude and longitude. At the same time, location is displayed on LCD. Finally, Google map displays the location and name of the place on cell phone. Thus, owner/user will be able to continuously monitor a moving vehicle using the cell phone. In order to show the feasibility and effectiveness of the system, this work presents experimental result of the vehicle tracking system. The proposed system is user friendly and ensures safety and surveillance at low maintenance cost.
车辆跟踪系统对于从任何地点在任何时间跟踪车辆的运动是非常有用的。本文采用全球定位系统(GPS)和全球移动通信系统(GSM)技术,实现了基于谷歌地图和Arduino的实时车辆跟踪系统。GPS模块定时提供地理坐标。然后,GSM模块将车辆的位置以经纬度的形式传输到车主/用户的手机上。同时,位置显示在LCD上。最后,谷歌地图在手机上显示位置和地点的名称。因此,车主/用户将能够使用手机持续监控移动的车辆。为了证明该系统的可行性和有效性,本文给出了车辆跟踪系统的实验结果。该系统操作方便,维护成本低,安全可靠。
