Yashvanth Kumar Guntupalli, Vemula Sai Saketh, S. Amudheswaran, Devashish S Vaishnav
Recommendation system is an information filtering application which anticipates the user's ratings by considering their previous judgements. These systems are an extensive aspect of most state-of-the-art applications. The highly accessible data on the internet is playing a dominant role in these systems. Collaborative filtering is one of the mechanisms of building a recommendation system which when fabricated with the ALS algorithm promises stunning results. This is because of the two-step iterative matrix factorisation approach of ALS. This recommendation system has been built using Amazon food product reviews on Apache Spark by servicing a master and few slave nodes. PySpark's ml library has been used for constructing the ALS model and RDD were utilised for handling the colossal amount of data. Composing the model over 50 ranks i.e., the total count of features chosen. Then the top 3 products which the user might prefer will be recommended.

Rami Mohaisen, M. Al-Mistarihi, Khalid A. Darabkh
This paper analyzes the performance of a two-hop DF cooperative network over different types of fading channels with the availability of multiple $L$ interfering signals nearby the destination. The outage probability is thoroughly analyzed, and observations are made to specify the determinate factors that will influence the system's behavior. Since it is nearly hard to derive the exact expression of the outage probability, we derived an approximated tight closed form expression.

Design and Analysis of Ultra High Speed 16 Channel Cascaded EDF A-DWDM Network with Post Dispersion Compensations Using Optimization of Fiber Bragg Grating 利用光纤光栅优化后色散补偿的超高速16通道级联EDF A-DWDM网络设计与分析
Mahendra Singh, Durgesh Kumar, D. Somwanshi
This article introduces an optimization of optical network system using the residual power of doped-fiber amplifier (EDFA) and optimized dispersion management by fiber bragg grating. If transmitted signal speed is increased to 8 * 5 Gbps, the dispersion is caused due to several reasons and pulse becomes indistinguishable at the destination. Its purpose is to use DCF in network to design and analyze the dispersion compensation system and here FBG used as a post-dispersion compensator. The main purpose is to achieve a constant gain over the entire transmission spectrum of the 16 narrow gap channels to match the amplitude gain of the DWDM system. The method was simulated using Optisystem 16.1 software package to achieve the uniformity of EDFA gain by changing the EDFA pump source power and system CW power. The planner gain is 41±0.4 decibels in the wavelength range from 1548 to 1556 nm, the NF close to 7 dB, the flattened EDFA gain at fiber length close to 8m, the frequency interval between channels is 0.5nm and dispersion significantly managed.
本文介绍了一种利用掺杂光纤放大器(EDFA)剩余功率和光纤光栅优化色散管理的光网络系统优化方法。当传输信号速度提高到8 * 5gbps时,由于多种原因导致色散,脉冲在目的地变得无法区分。其目的是利用DCF在网络中设计和分析色散补偿系统,并将光纤光栅用作色散后补偿器。其主要目的是在16个窄间隙信道的整个传输频谱上实现恒定增益,以匹配DWDM系统的幅度增益。采用Optisystem 16.1软件包对该方法进行仿真,通过改变EDFA泵源功率和系统连续波功率来实现EDFA增益的均匀性。在1548 ~ 1556 nm波长范围内,规划器增益为41±0.4分贝,NF接近7 dB,光纤长度接近8m的平坦EDFA增益,信道间频率间隔为0.5nm,色散得到明显控制。

Allocation of DG Units in Distribution System to Minimize Reactive Power Loss 配电系统中DG机组的配置以减少无功损耗
K. Sharma, Sarfaraz Nawaz
In today's scenario, in order to meet load demand in the distribution system, DG units play a key role in reducing real and reactive power losses. A rise in the demand for the distribution system at the loading centers has been overcome by growing in power generation. One solution to meeting the necessary load demand is to mitigate loss of power in the distribution system. Real Power can be maximized across the network by decreasing the system's reactive power losses. This paper introduces a new analytical approach as well as a new Power Voltage Sensitivity Factor (PVSF) constant that defines the optimal DG size and position. An objective function is utilized to determine the loss of reactive power when reinforced with distributed generators (DGs). To demonstrate the feasibility of the proposed approach, the radial distribution system has been evaluated on the standard IEEE 69-bus and outcomes obtained are contrasted to other approaches.
在当今的情况下,为了满足配电系统的负荷需求,DG机组在降低实际和无功功率损耗方面发挥着关键作用。由于发电量的增加,负荷中心配电系统的需求有所增加。满足必要负荷需求的一种解决方案是减轻配电系统中的电力损耗。通过减少系统的无功损耗,可以使整个网络的实际功率最大化。本文介绍了一种新的分析方法,以及一个新的功率电压敏感系数(PVSF)常数来定义DG的最佳尺寸和位置。利用目标函数确定分布式发电机加固时的无功损失。为了证明该方法的可行性,在标准IEEE 69总线上对径向配电系统进行了评估,并与其他方法进行了对比。

Timely detection of Seismic waves in Ground motion data using Improved S-Transform 基于改进s变换的地震动数据中地震波的及时检测
Ashish Sharma, S. Nanda
In Seismology, exact recognition of arrival times of seismic wave has been a key challenge for a geologist. The arrival time of body waves provides significant information about the hypocenter location, source systems and tomography analysis. In this paper, Linear Gaussian kernel window method is incorporated with S-transform for time frequency decomposition of seismic signals. It progressively controls the window width to increase the concentration of energy and reduce the smearing effect in time-frequency region and minimize the spreading of wave. The IST is applied for time identification body wave components called Primary and Secondary waves. The accelerograph of famous earthquakes of San Francisco in 2014 and California in 2012 regions have been used for the analysis. The superiority of the results obtained from IST is compared with benchmark techniques continuous Wavelet Transform (CWT), Discrete Wavelet Transform (DWT) and S-Transform (ST) in terms of time detection.
在地震学中,准确识别地震波的到达时间一直是地质学家面临的关键挑战。体波的到达时间为震源位置、震源系统和断层扫描分析提供了重要信息。本文将线性高斯核窗法与s变换相结合,对地震信号进行时频分解。逐步控制窗宽,增加能量的集中,减少时频区域的涂抹效应,使波的传播最小化。IST用于时间识别体波分量,称为一次波和二次波。使用了2014年旧金山和2012年加利福尼亚地区的著名地震加速度计进行分析。对比了连续小波变换(CWT)、离散小波变换(DWT)和s变换(ST)等基准技术在时间检测方面的优越性。

Dual Mode OFDM-IM with Multiple Choice of Constellations 具有多种星座选择的双模OFDM-IM
A. K. Gandharva, K. Akshay, J. C. L Ramoji, Arpita Thakre
Orthogonal frequency division multiplexing is a multicarrier digital modulation technique that is extensively used in modern wireless communication systems. Index Modulation combined with orthogonal frequency division multiplexing lead to improved spectral efficiency. Dual mode orthogonal frequency division multiplexing with index modulation aims at increasing spectral efficiency even further. The improved spectral efficiency comes at a cost of increased signal detection complexity at receiver side. Here we propose yet another index modulation aided dual mode orthogonal frequency division multiplexing technique where the two modes can be selected from a set of four modes or constellations. By doing this we increased the proportion of index bits compared to data bits, eventually leading to an increase in spectral efficiency. This paper describes in detail our proposed method, the accompanying transmission and receiver detection technique. We also illustrate the spectral and energy efficiency of proposed technique and compare its performance with its nearest counterparts.
正交频分复用技术是一种广泛应用于现代无线通信系统的多载波数字调制技术。指数调制与正交频分复用相结合,提高了频谱效率。带折射率调制的双模正交频分复用旨在进一步提高频谱效率。频谱效率的提高是以接收机端的信号检测复杂度增加为代价的。在这里,我们提出了另一种索引调制辅助双模正交频分复用技术,其中两种模式可以从一组四种模式或星座中选择。通过这样做,我们增加了索引位相对于数据位的比例,最终导致频谱效率的提高。本文详细介绍了我们提出的方法以及相应的发射和接收检测技术。我们还说明了所提出的技术的频谱和能量效率,并将其性能与最接近的同类产品进行了比较。

A Design Approach for Mac Unit Using Vedic Multiplier 一种基于Vedic乘法器的Mac单元设计方法
Aditi Chhabra, J. Dhanoa
Machine learning problems have been efficiently solved by using Artificial Neural Networks (ANNs). The realization of neural networks on hardware have been shown to provide more significant advantages. In digital neural networks, the weight-input multiplication is an important step. In this paper, a comparative study between different configurations of Vedic multipliers and traditional array multipliers has been performed and further, the hardware implementation of the MAC unit has been performed using VHDL. MAC unit of ANN requires repetitive use of adders and multipliers. The aim behind the comparison is to obtain an alternative approach for the realization of the MAC unit of the neural network. This paper further proposes a network using the alternative multiplier in place of the normal array multiplier. The circuit implemented in this paper has been dedicated to a given data set. The testing accuracy by the network is achieved keeping in mind the precision of the multiplier.

QR code is a two-dimensional matrix barcode which is in the form of label and can be translate by machine-readable optical devices. Each QR code represents its own unique code patterns. It can be scans and retrieves using devices such as smartphones, tablets or computer cameras that have QR code scanning application. In hospitals and clinics, medication prescriptions are given to patients which display the date, patient's name, medication name, dose and instructions. However, details information of each medication prescription are not given. In such, there is a need for patient to retrieve the details of each prescription. The existing QR codes also provide limited information and exclude Material Safety Data Sheet. Importantly, the medication prescription information must be from the trusted resources. Therefore, this research objectives are to develop Medication Prescription QR Code, conduct a case study in Universiti Teknologi MARA in Kedah and test users' acceptance. The methodology includes analysis, design, implementation, testing, deployment and maintenance phases. This study introduces Medication Prescription QR code that offers efficient method for patients to retrieve prescribe medicine detailes information. It provides fast and precise information of specific medicines such as indications, interactions, special precautions, adverse reactions and potential hazards, and information from the Material Safety Data Sheet. Implementation of QR codes able to reduce the cost and resources, and can promote towards green environment. The results indicate that Medication Prescription QR Code has good potential to be used by patients and is a value added for medical practitioners and manufacturers. In addition, it has been recognized and received patent from Intellectual Property Corporation of Malaysia.
二维码是一种以标签形式存在的二维矩阵条码,可以通过机读光学设备进行翻译。每个QR码代表其独特的代码模式。它可以通过智能手机、平板电脑或电脑摄像头等具有二维码扫描应用程序的设备进行扫描和检索。在医院和诊所,给病人开的药物处方上显示日期、病人姓名、药物名称、剂量和说明。但是,没有给出每种药物处方的详细信息。在这种情况下,患者需要检索每个处方的详细信息。现有的QR码也提供有限的信息,不包括材料安全数据表。重要的是,药物处方信息必须来自可信资源。因此,本研究的目的是开发药物处方QR Code,并在kedaah的Universiti Teknologi MARA进行案例研究,并测试用户的接受程度。该方法包括分析、设计、实现、测试、部署和维护阶段。本研究引入了药物处方二维码,为患者检索处方药物详细信息提供了一种高效的方法。它提供了特定药物的快速和准确信息,如适应症、相互作用、特殊预防措施、不良反应和潜在危害,以及来自物质安全数据表的信息。实施二维码能够降低成本和资源,并能促进绿色环保。结果表明,药物处方QR码具有良好的被患者使用的潜力,对医疗从业者和制造商来说是一种增值。此外,该产品还获得了马来西亚知识产权公司的认可和专利。
