Offloading SLAM for Indoor Mobile Robots with Edge-Fog-Cloud Computing 基于边缘雾云计算的室内移动机器人SLAM卸载
V. Sarker, J. P. Queralta, Tuan Anh Nguyen Gia, H. Tenhunen, Tomi Westerlund
Indoor mobile robots are widely used in industrial environments such as large logistic warehouses. They are often in charge of collecting or sorting products. For such robots, computation-intensive operations account for a significant percentage of the total energy consumption and consequently affect battery life. Besides, in order to keep both the power consumption and hardware complexity low, simple micro-controllers or single-board computers are used as onboard local control units. This limits the computational capabilities of robots and consequently their performance. Offloading heavy computation to Cloud servers has been a widely used approach to solve this problem for cases where large amounts of sensor data such as real-time video feeds need to be analyzed. More recently, Fog and Edge computing are being leveraged for offloading tasks such as image processing and complex navigation algorithms involving non-linear mathematical operations. In this paper, we present a system architecture for offloading computationally expensive localization and mapping tasks to smart Edge gateways which use Fog services. We show how Edge computing brings computational capabilities of the Cloud to the robot environment without compromising operational reliability due to connection issues. Furthermore, we analyze the power consumption of a prototype robot vehicle in different modes and show how battery life can be significantly improved by moving the processing of data to the Edge layer.
室内移动机器人广泛应用于大型物流仓库等工业环境。他们通常负责收集或分类产品。对于这样的机器人,计算密集型操作占总能耗的很大比例,因此影响电池寿命。此外,为了保持低功耗和硬件复杂性,使用简单的微控制器或单板计算机作为板载本地控制单元。这限制了机器人的计算能力,从而限制了它们的性能。在需要分析大量传感器数据(如实时视频馈送)的情况下,将繁重的计算任务卸载到云服务器上已经成为解决这一问题的一种广泛使用的方法。最近,雾和边缘计算被用于卸载图像处理和涉及非线性数学运算的复杂导航算法等任务。在本文中,我们提出了一种系统架构,用于将计算上昂贵的定位和映射任务卸载到使用雾服务的智能边缘网关。我们将展示边缘计算如何将云计算能力引入机器人环境,而不会因连接问题而影响操作可靠性。此外,我们分析了原型机器人车辆在不同模式下的功耗,并展示了如何通过将数据处理移动到边缘层来显着提高电池寿命。

Nesar Uddin, S. Nahian, Md. Saiful Islam, Jewel Sikder Joy
This research paper proposes an energy generation system to utilize renewable energy for off-grid area of Bangladesh which includes hill track areas and Rohinga camps. Most of the hill track areas and Rohinga camps did not access electricity. Again, present system loss of electricity is a great problem in Bangladesh. The main purpose of the paper is to design an optimal hybrid energy management system using HOMER control technique and Fuzzy Logic Controller (FLC). The system consists of PV arrays, Biogas generator, diesel generator, converter and Battery. We have used the HOMER software for effective size calculation of the system components. FLC is used to manage the obtained power from renewable energy sources efficiently. Optimum fuzzy rules are designed to control the shifting of the switches considering the load profiles and availability of renewable sources on a given period of time. For the justification of cost effectiveness and power management system simulation result from our control strategy have been compared with other prevailing systems. In addition, we obtain lower CO2 emission from the system renewable fraction which indicates the environment friendliness. This simulation result provides a summary to utilize renewable energy with properly on recent energy crises in Bangladesh.

Non-Functional Requirements Classification with Feature Extraction and Machine Learning: An Empirical Study 基于特征提取和机器学习的非功能需求分类:实证研究
Md Ariful Haque, Md. Abdur Rahman, Md. Saeed Siddik
Non-Functional Requirements (NFR) describe a set of quality attributes required for a software such as security, reliability, performance, etc. Extracting and considering NFR from software requirement specification can help developers to deliver quality software which meets users expectations completely. Since, the functional and non-functional requirements are mixed together within the same SRS, it requires a lot of human effort for distinguishing them. This paper proposed automatic NFR classification approach for quality software development by combining machine learning feature extraction and classification techniques. An empirical study with seven machine learning algorithms and four feature selection approaches have been applied to automatically classify NFR for finding out the best pair. The experiments were measured with statistical analysis including precision, recall, F1-score, and accuracy of the classification results through all the combinations of the techniques and algorithms. It is found that, SGD SVM classifier achieves best results where precision, recall, F1-score, and accuracy reported as 0.66, 0.61, 0.61, and 0.76 respectively. Additionally, TF-IDF (character level) feature extraction technique illustrated higher average score than others.

Efficient Compression Scheme for Large Natural Text Using Zipf Distribution 使用Zipf分布的大型自然文本的有效压缩方案
Md. Ashiq Mahmood, K. Hasan
Data compression is the way toward modifying, encoding or changing over the bit structure of data in such a way that it expends less space. Character encoding is somewhat related to data compression which represents a character by some sort of encoding framework. Encoding is the way toward putting a succession of characters into a specific arrangement for effective transmission or capacity. Compression of data covers a giant domain of employments including information correspondence, information storing and database development. In this paper we propose an efficient and new compression algorithm for large natural datasets where any characters is encoded by 5 bits called 5-Bit Compression (5BC). The algorithm manages an encoding procedure by 5 bits for any characters in English and Bangla using table look up. The look up table is constructed by using Zipf distribution. The Zipf distribution is a discrete distribution of commonly used characters in different languages. 8 bit characters are converted to 5 bits by parting the characters into 7 sets and utilizing them in a solitary table. The character’s location is then used uniquely encoding by 5 bits. The text can be compressed by 5BC is more than 60% of the actual text. The algorithm for decompression to recover the original data is depicted also. After the output string of 5BC is produced, LZW and Huffman techniques further compress the output string. Optimistic performance is demonstrated by our experimental result.
数据压缩是对数据的位结构进行修改、编码或改变的一种方式,这种方式消耗的空间更少。字符编码在某种程度上与数据压缩有关,它通过某种编码框架表示字符。编码是将一串字符按特定的顺序排列以达到有效传输或容量的一种方法。数据压缩涉及的领域非常广泛,包括信息通信、信息存储和数据库开发。在本文中,我们提出了一种高效的新的压缩算法,用于大型自然数据集,其中任何字符都由5位编码,称为5位压缩(5BC)。该算法通过表查找对英语和孟加拉语中任意字符的编码过程进行5位的管理。查找表是使用Zipf分布构造的。Zipf分布是不同语言中常用字符的离散分布。通过将字符分成7组并在单独的表中使用,将8位字符转换为5位字符。字符的位置被唯一地编码为5位。5BC所能压缩的文本是实际文本的60%以上。文中还描述了恢复原始数据的解压缩算法。在产生5BC的输出字符串后,LZW和Huffman技术进一步压缩输出字符串。我们的实验结果证明了乐观的性能。

An investigation on the surface states evolution of polycrystalline silicon nanowires for gas sensing application 气体传感用多晶硅纳米线表面态演变研究
M. Hakim, Afrida Arshad, S. Shoma, U. Saha
We perform a feasibility study on the application of thin film polycrystalline silicon (polysilicon) nanowires for gas sensing application upon exposure into different gas ambient. The nano-sensors are developed in a relatively cheap reactive ion etching system using a low-density plasma based etch and mature 3 micron lithography. Systematic measurements in air, vacuum, hydrogen and isopropyl alcohol demonstrate promising gas sensitivity and impressive response/recovery times in room temperature. The modification of surface states in nanowires upon exposure into different gas ambient is confirmed through 3D numerical simulation. This investigation demonstrates the potential of polysilicon nanowires for detecting molecules in gas phase thereby reveals that the polysilicon nanowire sensor is promising for a simple, low cost, manufacturable route for gas-sensor fabrication.

Analysis of Air Foils and Design of Blades for a Low-Speed 250W Vertical Axis Wind Turbine Suitable for Coastal Areas of Bangladesh 适用于孟加拉国沿海地区的250W低速垂直轴风力机的翼型分析与叶片设计
M. Murshed, Md. Yeasin Arafat, M. Abdur Razzak
Harnessing wind energy across all over the globe increasing due to raw energy availability and uses of a higher grade of optimized technology. Mostly European countries are adopted this energy expansion over other regions because of the huge availability of wind in these areas. The potential of wind energy in Bangladesh is not tremendously good but has some good prospect if modern technology and greater optimization can take place. Presently the coastal regions, as well as Cox's Bazar, Chittagong, Teknaf, Patenga, Mongla, and Kutubdia, are a most suitable point to harnessing or working on wind energy. Although the velocity of wind in these regions is not perfect for harnessing energy from a big size wind turbine rather it is quite capable to generate electricity from small size turbine in an efficient way. Vertical axis wind turbine (VAWT) is perfectly appropriate for extracting the maximum power from wind in such these low wind speed area. NACA foil is mainly prioritized to build this type small sized VAWT system because of the low maintained mechanism. The small-sized VAWT system needs more analyzed wind data to work in an optimized condition. The positions and efficiency of the turbine system are highly depend on the blade lift and drag coefficient because of random wind flow directions. Counting all these points the main objective is to examine the wind data available in these areas and design a vertical axis wind turbine (VAWT) suitable for small sized electricity generation system in an efficient way by optimizing turbine blades and its foil mechanism.
由于原始能源的可用性和更高等级优化技术的使用,在全球范围内利用风能的情况正在增加。大多数欧洲国家在其他地区采用这种能源扩张,因为这些地区有大量的风能。孟加拉国的风能潜力不是特别好,但如果采用现代技术并进行更大的优化,前景会很好。目前,沿海地区以及考克斯巴扎尔、吉大港、特克纳夫、Patenga、勐拉和库图布迪亚是最适合利用或开发风能的地方。虽然这些地区的风速对于利用大型风力涡轮机的能量来说并不完美,但它相当有能力以有效的方式利用小型风力涡轮机发电。垂直轴风力发电机(VAWT)非常适合在这种低风速地区从风力中提取最大功率。由于低维护机制,NACA箔主要优先用于构建这种小型VAWT系统。小型VAWT系统需要更多的风分析数据才能在优化状态下工作。由于风向的随机性,涡轮系统的位置和效率在很大程度上取决于叶片的升力和阻力系数。计算所有这些点的主要目标是检查这些地区可用的风力数据,并通过优化涡轮机叶片及其箔机构,以有效的方式设计适合小型发电系统的垂直轴风力涡轮机(VAWT)。

Md. Waqeeb T. S. Chowdhury, M. Alam, Abidur Rahman
In this paper a model is proposed and explained in brief on how to manage loads efficiently from the utility end using Power Line Communications (PLC). The model employs the principle of PLC along with the industry based technology called X10 to serve the purpose. The loads at the user end are classified according to its importance and power consuming characteristics, and are allotted X10 device codes. Each power consuming utility is assigned an IP address, which aids in selecting a particular load or a group of loads as per requirements. A simple schematic diagram that illustrates the process is also provided. Moreover, since the used PLC scheme is the Narrow-Band PLC (NB-PLC), a simulation based result is also provided that defines a small segment of the entire NB-PLC frequency range that is suitable for the purpose.

Hybrid renewable energy systems (HRESs) have a great potentiality to provide a more reliable power supply, when compared to a system based on a standalone source. The hybrid system supports the modular design that can mitigate problems associated with the use of individual sources by combining them all in a systematic procedure. In this paper, comparative study for analyzing the effects of four different systems namely: photovoltaic (PV) stand-alone with storage unit, PV-battery-grid system, PV-diesel-battery system, and PV-diesel-grid system are carried out using the HOMER software. Furthermore, an optimal cost analysis is also conducted based on net present cost (NPC). In addition, using real satellite footage with the help of HELIOSCOPE software, an effective configuration of PV array is designed based on real solar irradiance data. The cost optimization of the HRES is developed on the basis of the sets of real data collected from Khulna University of Engineering and Technology (KUET), Khulna, Bangladesh. The study reveals that the approach with PV-diesel-battery system has comparatively lower NPC, less fuel cost, and a limited carbon footprint along with excess electricity to contribute to the national grid.
与基于独立能源的系统相比,混合可再生能源系统(HRESs)在提供更可靠的电力供应方面具有巨大的潜力。混合系统支持模块化设计,通过将所有源组合在一个系统程序中,可以减轻与使用单个源相关的问题。本文利用HOMER软件对光伏单机带存储单元、光伏-电池-并网、光伏-柴油-电池系统、光伏-柴油-并网四种不同系统的发电效果进行了对比研究。在此基础上,进行了基于净当前成本的最优成本分析。此外,利用真实的卫星影像,借助HELIOSCOPE软件,基于真实太阳辐照度数据,设计了有效的光伏阵列配置。HRES的成本优化是根据从孟加拉国库尔纳的库尔纳工程技术大学(KUET)收集的真实数据集开发的。研究表明,使用光伏-柴油电池系统的方法具有相对较低的NPC,更低的燃料成本,有限的碳足迹以及多余的电力为国家电网做出贡献。

Virtual Image from EEG to Recognize Appropriate Emotion using Convolutional Neural Network 利用卷积神经网络识别脑电虚拟图像中的适当情绪
M. Islam, Mohiudding Ahmad
Electroencephalogram (EEG) that measures the electrical activity of the brain has been used extensively to recognize emotion. Normally feature based emotion recognition requires a strong effort to design the perfect feature or feature set related to the classification of emotion. To curtail the manual human effort we designed a model by using a virtual image from EEG with Convolutional Neural Network (CNN). Initially, we calculated Pearson’s correlation coefficients form different sub-bands of EEG to formulate a virtual image. Later, this virtual image was fed into a CNN architecture to classify emotion. We made two distinct protocols; between these, protocol-1 was to classify positive and negative emotion and protocol-2 was to classify four distinct emotions. An overall maximum accuracy of 81.51% on valence and 79.42% on arousal was obtained by using internationally authorized DEAP dataset. Our proposed method is helpful in recognizing emotions efficiently.
测量大脑电活动的脑电图(EEG)已被广泛用于识别情绪。通常,基于特征的情感识别需要努力设计出与情感分类相关的完美特征或特征集。为了减少人工操作的工作量,我们利用卷积神经网络(CNN)设计了一个脑电虚拟图像模型。首先,我们计算脑电不同子带的Pearson相关系数,形成虚拟图像。随后,将该虚拟图像输入CNN架构进行情绪分类。我们制定了两个不同的协议;其中,方案1是对积极和消极情绪进行分类,方案2是对四种不同的情绪进行分类。使用国际认可的DEAP数据,对效价和觉醒的总体最高准确率分别为81.51%和79.42%。我们提出的方法有助于有效地识别情绪。
