Computational Data Analysis on Global Energy and COVID-19 Pandemic
Momina Shaheen, Muhammad Junaid Anjum, Faizan Ahmad, Aimen Anum
Статья научная
A global consumption of energy is primarily met by the renewable and non-renewable energy production resources. It is necessary to understand the pattern of global energy consumption in past to refine the overall energy policy for an upcoming demand of the energy market. The consumption of energy and its insights are helpful for grid management and forecasting. This paper presents the consumption of renewable and non-renewable energy resources by different nations and presents the analysis of the impact of COVID19 pandemic over the consumption of Energy. From the detailed analysis in this study, it is evident that all countries are shifting their interest to use renewable sources of energy generation. The global consumption of energy was constantly increasing up to 4% each year for three decades (1990 to 2020). However, during COVID-19 outbreak, energy consumption shows a downward trend in 2020 to -4%, which is twice lower than the decrement of energy consumption observed 2008-2009 economic crisis. The COVID-19 pandemic has seriously affected energy consumption of all countries in the world.

T. Saha, M. K. H. Jewel, M. N. Mostakim, N. H. Bhuiyan, M. S. Ali, M. K. Rahman, H. K. Ghosh, Md. Khalid Hossain
Статья научная
An automated greenhouse is a framework that utilizes nursery innovations to make a positive ecological condition virtually to develop ideal creation of plants. Controlling climatic conditions are one of the most critical challenges in agribusiness. In like manner, a robotized nursery framework has been developed to accomplish observations and controlling of the climatic parameters which is straightforwardly or in a roundabout way that administers the plants development and generation. In a nursery using greenhouse structure that is made with glass or plastic it warms up from approaching obvious sun oriented radiation which is consumed by the plants and absorbed by the surface. Eventually air is warmed by the warmth from hot inside surfaces and held within the nursery dividers that makes the environment inside it warmer. With the association of present day innovations, this research takes a risk to actualize these frameworks for farming with no human consideration. The motivation behind this exploration is to make an innovation that makes exceedingly exact environment in a work sparing angle. In this work an Atmega328 MCU is utilized to do some predefined tasks, made by some specific codes with the help of an Arduino prototyping board. The system projects the parameters in a display as well as controls four vital parameters like temperature, light, humidity and soil moisture to accomplish viability and functionality of nursery environment control gadgets.

Cooperative Spectrum Sensing and Weighted-Clustering Algorithm for Cognitive Radio Network
Huiheng Liu, Wei Chen
Статья научная
Cognitive radio is a promising technique for efficient utilization of idle authorized spectrum since it is able to sense the spectrum and reuse the frequency when the primary user is absent. In order to overcome the fading, shadowing or hidden terminals in independent detection, cooperative detection is presented. The performance of cooperative sensing is studied in this paper. To enhance the sensing ability, some weighted-cooperative spectrum sensing techniques have been proposed. In this paper, different from the previous studies, we propose a novel weighted-clustering cooperative spectrum sensing algorithm based on distances for cognitive radio network. We firstly classify the secondary users into a few clusters according to several existent methods, and then use cluster-head to collect the observation results come from different secondary users in the same cluster and make a cluster-decision. Considering the different distances between the clusters and the fusion center, different weightings are used to weight the cluster-decisions before combining. The simulation results show that our proposed method improve the probability of detection and reduce the probability of error.

Cost Modeling for SOC Modules Testing
Balwinder Singh, Arun Khosla, Sukhleen B. Narang
Статья научная
The complexity of the system design is increasing very rapidly as the number of transistors on Integrated Circuits (IC) doubles as per Moore’s law. There is big challenge of testing this complex VLSI circuit, in which whole system is integrated into a single chip called System on Chip (SOC). Cost of testing the SOC is also increasing with complexity. Cost modeling plays a vital role in reduction of test cost and time to market. This paper includes the cost modeling of the SOC Module testing which contains both analog and digital modules. The various test cost parameters and equations are considered from the previous work. The mathematical relations are developed for cost modeling to test the SOC further cost modeling equations are modeled in Graphical User Interface (GUI) in MATLAB, which can be used as a cost estimation tool. A case study is done to calculate the cost of the SOC testing due to Logic Built in Self Test (LBIST) and Memory Built in Self Test (MBIST). VLSI Test engineers can take the benefits of such cost estimation tools for test planning.

Sahar A. El_Rahman, Sahar S. Shabanah
Статья научная
Accreditation is considered as one of the major aspects of ABET, where educational institutions continuously develop the quality of academic programs to achieve it. For the most part of this continuous development needs, the programs determine definite and measured objectives for their students, evaluate their efforts to achieve these objectives, and amend their programs based on the results of that assessment. In addition to providing educational institutions an organized strategy to appraise and develop their programs. The primary focal point to prepare for accreditation is the learning objectives and program outcomes assessment. So, College of Computer and information Sciences (CCIS) at Princess Nourah Bint Abdulrahman (PNU) needs to fulfill ABET criteria to achieve the outcomes. So, CCIS need a system to achieve course assessment matrix without wasting the time and efforts. This system will help the staff members in identifying student learning objectives that are expected to achieve as well as to identify assessment tools and evaluation feedback for each topic. This paper describes Course and Student Management System (CSMS) established to address a course assessment matrix, and help achieve department-stated objectives. Whereas, CSMS is a web based system provides many features to facilitate the creation of articulation matrix, course assessment based on students learning objectives, the student's evaluation and tracking attendance of students. This system is considered as a new method of creating the course assessment matrix that will help the department head, instructors and course coordinator. It is user friendly and interactive interface, saving the time and efforts.
