Scenario of Solid Waste Generation Disposal and Transportation at the University of Rajshahi 拉杰沙希大学固体废物产生、处置和运输情景
Md. Rakib Alam Jewel, Md. Abdur Rahman
This paper presents an investigation on present scenario of solid waste generation, disposal and transportation at the University of Rajshahi and at same time focus is given on quantitative analysis and energy calculation of the wastes in the university. Quantitative analysis shows that the average amount of solid waste generated per day is 7.6 ton and the calculated average per capita per day is 0.57kg ± 0.44 although these numbers may vary from region to region. The total waste generated per month and per year is approximately 229.5 ton and 2754.9 ton respectively. The estimated lower heating value (LHV) of the waste is 83412.3MJ/day from where 4.63MWh electricity can be generated using conventional waste fired power plant (WTE) with efficiency 20%. Although literature study on WTE plant showed that for economically viable WTE plant the throughput must be at least 100ton/d or above which means the waste produced in the university per day is not enough for installing a feasible plant but considering whole Rajshahi town a plant of higher throughput can be installed and economically manageable. Otherwise only for environmental benefits the waste can be burned and diminished by small scale modular incinerator.
本文对拉杰沙希大学固体废物的产生、处置和运输现状进行了调查,同时重点对大学固体废物的定量分析和能量计算进行了研究。定量分析表明,虽然这些数字因地区而异,但平均每天产生的固体废物量为7.6吨,计算得出的人均每天平均为0.57kg±0.44。每月和每年产生的废物总量分别约为229.5吨和2754.9吨。估计废物的较低热值(LHV)为83412.3MJ/天,使用传统的废物燃烧发电厂(WTE)可以产生4.63MWh的电力,效率为20%。虽然文献研究表明,对于经济上可行的WTE工厂,吞吐量必须至少为100吨/天或以上,这意味着大学每天产生的废物不足以安装一个可行的工厂,但考虑到整个Rajshahi镇,可以安装一个更高吞吐量的工厂,并且经济上可管理。否则,仅为了环境效益,废物可以通过小型模块化焚烧炉进行焚烧和减少。

Misadjustment Measurement with Normalized Weighted Noise Covariance based LMS Algorithm 基于归一化加权噪声协方差LMS算法的失调测量
Md. Shoriful Islam, Rubaiyat Yasmin, Shihab Kaviraz, Most.Meftahul Zannat
In this paper, a new refined technique called Normalized Weighted Noise Covariance based LMS (NWC-LMS) technique has been proposed to measure misadjustment of an adaptive filtering system. This technique is aimed to track the measured misadjustment properly. Several techniques had been developed during past years to analyze and calculate the measured misadjustment based on weight noise covariance matrix. However there are still significant error in misadjustment measurement to the calculated misadjustment. The performance of the proposed NWC-LMS technique is verified by computer simulations for an unknown system with additive white Gaussian noise. From the simulation results it is observed that even for larger value of step size, NWC-LMS technique can predict the misadjustment better than the conventional techniques. Around 37 % error improvement is achieved for the larger step size 0.04 with same input condition with our proposed NWC-LMS technique.
本文提出了一种新的改进技术——基于归一化加权噪声协方差的LMS (NWC-LMS)技术来测量自适应滤波系统的失调。该技术的目的是正确跟踪测量误差。近年来发展了几种基于权值噪声协方差矩阵的测量误差分析和计算技术。然而,对计算出的误差差进行测量时仍存在较大误差。通过对具有加性高斯白噪声的未知系统的计算机仿真,验证了所提出的NWC-LMS技术的性能。仿真结果表明,当步长较大时,NWC-LMS技术也能较好地预测误差。在相同的输入条件下,对于较大的步长0.04,我们提出的NWC-LMS技术实现了约37%的误差改进。

Efficient FPGA Implementation of Unified Point Operation for Twisted Edward Curve Cryptography 扭曲爱德华曲线密码统一点运算的高效FPGA实现
Md. Rownak Hossain, Md. Selim Hossain, Yinan Kong
Combination of efficient point operation architecture and high intractability feature of cryptographic curve optimizes the performance of the Edward curve cryptography (EdCC) processor ensuring desired security. This research employs the most recently invented twisted Edward curve for performing point operation. A novel architecture of unified point operation has been designed over the 256-bit prime field which can execute Edward curve point doubling and point addition in one module instead of two divide modules. The proposed architecture has been implemented on Virtex-5 field-programmable gate array technology and achieved 5.48 $mu$ s computational delay and only 10% of available slices for 256-bit point operation. Our design reduces almost 50% of the required clock cycles compared to other designs. Also, it assures a better security characteristic as to the conventional approach. To our best knowledge, the proposed architecture provides better performance in terms of throughput on FPGA than the other work which is effective for the design of the EdCC processor.

Subir Datta, Akibul Islam, Tridip Saikia, S. Adhikari
The performance of a grid connected permanent magnet synchronous generator (PMSG) based wind turbine mT) system under varying wind velocity is studied in this paper. To achieve variable speed and constant frequency operation, two vector control schemes are adopted for controlling both the converters. Field oriented based vector control scheme is used to control Machine Side Converter (MSC) and grid oriented based vector control scheme is used to control Grid Side Converter (GS C). Maximum Power Point Tracker (MPPT) is also playing a very important role to extract maximum power from wind and hence, perturb and observe (P & O) algorithm is used. Simulation of the complete system is done in MATLAB/Simulink platform and time domain results are taken under varying wind velocity and analyzed those results in details.

S. Biswas, M. Karim, A. Rajib, M. A. Rahman
Researchers are very much eager to exploit renewable energy whereas non-renewable energy is decreasing day by day. Moreover, non-renewable energy is not suited for the environment due to emission of CO2 as well as global warming is another problem. Solar energy is the vital candidate to attain the goal due to their availability, clean and this is environmental friendly. In this work, Undoped and copper doped zinc oxide (ZnO) thin films have been prepared on glass substrate by sol-gel spin coating method. In order to improve the crystalline quality and stoichiometry, as-deposited films were further annealed at 400°C in air for 1 hr. FT-IR Spectroscopy, XRD and UV—Visible Spectroscopy have been used in the present study to understand the variation of structural, electrical and optical properties with doping concentration. Structural analysis reveals the polycrystalline nature of the bare-ZnO thin films. Cu doped ZnO thin films also showed the polycrystalline nature with decreased crystallite size upon increasing the doping concentrations of the thin films. Finally FTO/ZnO/ZnO:Cu device structure have been fabricated on FTO coated glass substrate and I-V characteristics of FTO/ZnO/ZnO:Cu device structure shows rectifying performance with very high leakage.
在不可再生能源日益减少的情况下,可再生能源的开发利用成为研究人员的迫切愿望。此外,不可再生能源不适合环境,因为二氧化碳的排放和全球变暖是另一个问题。由于太阳能的可用性、清洁性和环保性,它是实现这一目标的重要候选者。本文采用溶胶-凝胶自旋镀膜的方法在玻璃衬底上制备了未掺杂和掺杂铜的氧化锌薄膜。为了改善结晶质量和化学计量,沉积膜在400°C空气中进一步退火1小时。利用FT-IR光谱、XRD和uv -可见光光谱分析了掺杂浓度对结构、电学和光学性能的影响。结构分析揭示了裸露zno薄膜的多晶性质。随着掺杂浓度的增加,Cu掺杂ZnO薄膜也呈现出晶粒尺寸减小的多晶性质。最后在FTO镀膜玻璃基板上制备了FTO/ZnO/ZnO:Cu器件结构,FTO/ZnO/ZnO:Cu器件结构的I-V特性显示出具有很高漏电流的整流性能。

Depression Analysis from Social Media Data in Bangla Language using Long Short Term Memory (LSTM) Recurrent Neural Network Technique 使用长短期记忆(LSTM)递归神经网络技术分析孟加拉语社交媒体数据中的抑郁
A. H. Uddin, Durjoy Bapery, A. Arif
Human emotions like depression are inner sentiments of human beings which expose actual behaviors of a person. Analyzing and determining these type of emotions from people’s social activities in virtual world can be very helpful to understand their behaviors. Existing approaches may be useful for analyzing common sentiments, such as positive, negative or neutral expressions. However, human emotions, such as depression, are very critical and sometimes almost impossible to analyze using these approaches. In this work, we deployed Long Short Term Memory (LSTM) Deep Recurrent Network for depression analysis on Bangla social media data. We created a small dataset of Bangla tweets and stratified it. In this paper, we have shown the effects of hyper-parameter tuning and how it can be helpful for depression analysis on a small Bangla social media dataset. The result shows that 5 layered LSTM of size 128 with batch size 25, learning rate 0.0001 over 20 epochs, the depression detection accuracy is high for stratified dataset with repeated sampling. This result will help psychologists and other researchers to detect depression of individuals from their social activities in virtual world and help them to take necessary measures to prevent undesirable doings resulted from depression.
像抑郁这样的人类情绪是人类的内心情感,它暴露了一个人的实际行为。从人们在虚拟世界中的社交活动中分析和确定这些类型的情绪可以非常有助于理解他们的行为。现有的方法可能有助于分析常见的情绪,如积极的、消极的或中性的表达。然而,人类的情绪,如抑郁,是非常关键的,有时几乎不可能使用这些方法来分析。在这项工作中,我们部署了长短期记忆(LSTM)深度循环网络对孟加拉国社交媒体数据进行抑郁分析。我们创建了一个孟加拉语推文的小数据集,并对其进行了分层。在本文中,我们展示了超参数调整的影响,以及它如何有助于对一个小型孟加拉国社交媒体数据集的抑郁分析。结果表明,5层LSTM的规模为128,batch size为25,20 epoch的学习率为0.0001,对于重复采样的分层数据集,洼地检测准确率较高。这一结果将有助于心理学家和其他研究人员从虚拟世界的社交活动中发现个体的抑郁症,并帮助他们采取必要的措施来防止抑郁症导致的不良行为。

A Cryptographic Algorithm Based on ASCII and Number System Conversions along with a Cyclic Mathematical Function 一种基于ASCII和数字系统转换以及循环数学函数的密码算法
M. Moon, Md. Palash Uddin, M. I. Afjal, Md. Al Mamun, Md Abu Marjan, Mahjabin Nitu
Data encryption and decryption in an efficient manner are the challenging aspects of modern information theory. An efficient cryptology algorithm is introduced in this paper to offer comparatively higher security of data. In this algorithm, the plaintext to be encrypted is converted into unprintable characters. For encryption, a competent technique is applied based on ASCII and number system conversions which make this algorithm different from others. In the steps of the algorithm, each character of the plaintext is first converted into its equivalent ASCII (decimal) which is further converted to its equivalent octal and hexadecimal numbers. Then, using some matrix manipulations on the decimal, octal and hexadecimal representation of each character the character is transformed to 5 unprintable characters to form the intermediate cipher text. After that, every unprintable character in the intermediate cipher text is further converted into a different unprintable character using a cyclic mathematical function. Performing three steps of processing, the final encrypted text is produced that gives higher level of security. In this way, as there can have total 32 unprintable characters, it will take much time (for a plaintext of only 4 characters it takes 1.53 years to break down) if the intruders try to decrypt the original message with every probable combination. Though the length of the encrypted message is larger than original message in this proposed algorithm, it offers higher security for the real-time communications.
如何有效地对数据进行加密和解密是现代信息论研究的难点。本文介绍了一种有效的密码算法,可以提供较高的数据安全性。在这个算法中,要加密的明文被转换成不可打印的字符。在加密方面,采用了一种基于ASCII和数字系统转换的有效技术,使该算法区别于其他算法。在算法的步骤中,明文的每个字符首先转换为其等效的ASCII(十进制),然后再转换为其等效的八进制和十六进制数。然后,对每个字符的十进制、八进制和十六进制表示进行一些矩阵操作,将字符转换为5个不可打印的字符,形成中间密文。之后,使用循环数学函数将中间密文中的每个不可打印字符进一步转换为另一个不可打印字符。经过三个步骤的处理,最终生成的加密文本具有更高的安全性。这样,由于总共可能有32个不可打印的字符,如果入侵者试图用每种可能的组合解密原始消息,将花费很长时间(对于只有4个字符的明文,需要1.53年才能破解)。该算法虽然加密后的消息长度比原始消息长,但为实时通信提供了更高的安全性。

An efficient cryptology algorithm is introduced in this paper to offer comparatively higher security of data. In this algorithm, the plaintext to be encrypted is converted into unprintable characters. For encryption, a competent technique is applied based on ASCII and number system conversions which make this algorithm different from others. In the steps of the algorithm, each character of the plaintext is first converted into its equivalent ASCII (decimal) which is further converted to its equivalent octal and hexadecimal numbers. Then, using some matrix manipulations on the decimal, octal and hexadecimal representation of each character the character is transformed to 5 unprintable characters to form the intermediate cipher text. After that, every unprintable character in the intermediate cipher text is further converted into a different unprintable character using a cyclic mathematical function.

Evaluating the Effect of Transmission Range (TX) on the Performance of DSDV, AODV and DSR in Vehicular Ad hoc Network (VANET) Traffic Scenarios 车辆自组织网络(VANET)交通场景下传输距离(TX)对DSDV、AODV和DSR性能影响的评估

Vehicular Ad-hoc Networks (VANETs) is an emerging technology that derives from the well-established Mobile Adhoc Network (MANET). VANETs could face a great challenge arising from the dynamic nature of the nodes which occurs due to the frequent change in network topology. In a wireless network, Transmission Range (TX) is an essential part of successful packet delivery. In addition, TX affects network performance by changing the antenna height. If the transmission range is minimized or maximized, that consequently has effects on the network performance such as throughput, packet delivery ratio, the end to end delay and routing load. In this work, various scenarios have constructed to evaluate the effect of transmission range on DSDV, AODV and DSR routing protocol in a VANET highway design using Network Simulator (NS-2).
车载自组织网络(vanet)是一种新兴的技术,起源于成熟的移动自组织网络(MANET)。由于网络拓扑结构的频繁变化,节点的动态性给VANETs带来了巨大的挑战。在无线网络中,传输范围(TX)是数据包成功传递的重要组成部分。另外,TX通过改变天线高度影响网络性能。如果传输范围被最小化或最大化,则会对网络性能产生影响,例如吞吐量、数据包传送率、端到端延迟和路由负载。在这项工作中,利用网络模拟器(NS-2)构建了各种场景来评估传输距离对VANET高速公路设计中DSDV, AODV和DSR路由协议的影响。
