FPGA Based Pipelined Parallel Architecture for Fuzzy Logic Controller
Статья научная
This paper presents a high-speed VLSI fuzzy inference processor for the real-time applications using trapezoid-shaped membership functions. Analysis shows that the matching degree between two trapezoid-shaped membership functions can be obtained without traversing all the elements in the universal disclosure set of all possible conditions. A FPGA based pipelined parallel VLSI architecture has been proposed to take advantage of this basic idea, implemented on CycloneII-EP2C70F896C8. The controller is capable of processing fuzzified input. The proposed controller is designed for 2-input 1-output with maximum clock rate is 12.96 MHz and 275.33 MHz for 16 and 8 rules respectively. Thus, the inference speed is 0.81 and 34.41 MFLIPS for 16 and 8 rules, respectively.

Face Recognition in Multi Camera Network with Sh Feature
Статья научная
Multi view face recognition using multiple camera networks is an active research area. The main aim of this paper is to handle different pose variations in multi camera network and recognizing face from those videos. The traditional approaches handle the pose estimation explicitly ,the proposed work will handle the multiple views of the poses .For a given set of multi view video sequences we use particle filter to track the 3D location of the head. The texture map is generated by back projecting the multi view video. The proposed work is developed using the Spherical Harmonic (SH) representation of the face from the texture mapped on to the sphere. A robust feature is constructed based on the properties of SH projection.

Factors Affecting Failing the Programming Skill Examination of Computing Students
Статья научная
This descriptive study utilized a validated instrument to determine the factors that affect failing a programming skill examination. Through this finding, the study attempted to provide solutions to address the concerns of the students. The top three reasons why students failed the programming skill examination were the insufficient time dedicated to programming courses, self-inefficacy in programming, and unmatched question-time allotment. Overall, respondents attributed their failed mark in programming skill examination to question-related factors. This was confirmed through the use of regression analysis. Hence, it was concluded that students failed the programming skill examination because the perceived ability of the students in the programming skill examination did not correspond with the degree of difficulty of the programming skill examination questions. Further, the null hypothesis stating that student-related concerns do not predict the number of times the programming skill examination would be taken was partially rejected. Hence, it was recommended that the programming skill examination questions be calibrated based on the ability of the students. Future research directions were also presented.

The Malaysian university students faced various obstacles and had unmet needs when it is no longer an option to carry out virtual learning during the COVID-19 pandemic. These challenges faced by students call into question their actual use behaviour and true acceptance of the virtual learning environment (VLE). Thus, this study investigated the students’ actual use behaviour of VLEs, the factors that influence the actual use behaviour, the moderating effect of network connectivity on this relationship, and challenges faced by students while using this technology. The Technology Acceptance Model (TAM) and the Unified Theory Acceptance and Use of Technology 2 (UTAUT2) model were used as the theoretical basis of this study. An online survey was conducted among the International Medical University (IMU) students. The finding surmised that most of the students have adopted the VLE during the pandemic. The findings further revealed that factors such as hedonic motivation, perceived usefulness and perceived ease of use positively affect actual use behaviour, while network connectivity has no significant moderating effect on the relationship between the dimensions of the VLE and actual use behaviour. The key challenges include high cost associated with the VLE usage, and the students find the VLE is not entertaining or enjoyable. These results indicate that students will be inclined to accept the technology if there is high hedonic motivation, perceived usefulness, and perceived ease of use. Universities should focus on enhancing these factors to increase the acceptance of this technology among students, as VLEs have untapped potential for distance learning.

Factors that Impact on Rural and Remote Students’ Participation in Higher Education
Статья
This paper aims to explore the factors that impact on rural and remote students’ participation in higher education at university. The findings indicated that the students were familiar only with university scholarships, tertiary preparation program, and head start. Before admission, most students required information on pathways to university, admission requirements, scholarships, and range of courses and after admission they required information on academic support, tutorial assistance, library and IT services. This paper also suggests that universities need to evaluate the effectiveness of the services they offer to both attract and support rural and remote students to University if participation rates are to be raised.

Fault Repairing Strategy Selector for Service-Oriented Architecture
Статья научная
The success of a service oriented computing significantly depends on its reliability and availability. To achieve better reliability and availability, any fault of the service oriented computing has to be properly handled. Low performance on handling the service fault becomes the most proliferated challenge on fault handling approaches. In this paper, a priority based fault handling strategy selection approach for fault recovery of SOA (Service Oriented Architecture) is proposed using priority selector and fault handler. This approach starts from fault detection method and select the first priority level strategies promptly and if fault could not be handled by first highest level then fault handler selects the second level or intermediate priority level for average performance. As a final in the worst case, least level strategies are applied to resolve the faulty situation. Through experiment, the correctness of the proposed algorithm and the efficiency of the approach are proved. This approach results better performance and high rate of fault repairing.

Fault Tolerant ALU using Parity Preserving Reversible Logic Gates
Статья научная
Demand of reliable computing has been a major concern since the dawn of the electronic digital computer age. Reliable computing has various applications not only in the field of military, aerospace and communication but even contemporary commercial applications to fulfill today's automated life style. The tremendous growth in fabrication from small scale integration (SSI) to giant scale integration (GSI) is facing power dissipation as one of the main barriers. To overcome this barrier, researchers need to enter into the reversible logic domain. Making a reversible circuit robust or fault tolerant is much more difficult than a conventional logic circuit. Fault tolerance can be achieved in a system by using parity bits. The main aim of this paper is to come up with a new fault tolerant ALU design based on parity preserving reversible logic gates with improved quantum cost and power overhead as compare to existing fault tolerance based ALU designs. The most stringent requirement for fault tolerant ALU is in real time control system where faulty computation jeopardizes human life or other catastrophic effects.Implentation of proposed design is done using Xilinx ISE design suit 14.2 tool and its performance over existing ALU designs is qualitatively analyzed.

Favorable Trail Detection using ACO-Bellman Algorithm in VANETs
Статья научная
Vehicular ad hoc networks (VANETs) are the networks, which configured themselves, where the nodes are moving vehicles. These provide the communications required to deploy Intelligent Transportation Systems (ITS). A major dispute in VANETs is distribution of efficient and computable information because during communication nodes may leave or join the network dynamically. There is no guarantee about node availability at any given time, which leads to traffic problem, congestion problem. Therefore trailing the favorable path is a challengeable issue. Multiple routing algorithms have been developed for routing solution. In this paper the swarm-based algorithm has been presented, which helps to find out the optimal route using Bellman Ford algorithm. Ant colonization searches out the path using pheromones level. Higher the pheromone count of a route gives the optimal choice of path that can be used for packet delivery. Bellman Ford Algorithm optimizes the paths found by Ant Colony Optimization (ACO) by comparing the distance of source to all the nodes of network or cost given to the networks.

Focus Question based Inquiry Guided Learning for the Attainment of Course Learning Outcomes
Статья научная
Teaching and learning Methodologies in technical and engineering education has high impact on attainment of Graduate attributes. Studies have proved that class room teaching with mere usage of Black board (BB) and audio visual presentations doesn't effectively involve the student completely in learning. Also evaluation and assessment with midterm exams and end term exams may not give the complete picture of student learning progress. In fact in today's outcome based education the attainment of course learning outcomes require student centered teaching learning procedures and a continuous evaluation procedure. In this paper Focus question based Inquiry based learning an active teaching learning procedure also student centered is discussed. Also how this method is used for continuous assessment is also explained. It is successfully implemented to under graduate and post graduate students of Computer science and Information technology of engineering college, and the results are presented.

Framework for software code reviews and inspections in a classroom environment
Статья научная
Code reviews and inspections have the purpose to ensure that the code has sufficient quality to be released. It is generally seen as an economical way of finding errors, increase team productivity and sharing technical and product knowledge among team members. This approach is traditionally adopted in software development companies, but their practices may be useful in other contexts, such as in the process of learning software engineering. In this sense, this study proposes an innovative framework for conducting code reviews in a Computer Science course. The proposed framework can be applied in any object-oriented program language, and it is sufficiently concise to be applied in the classroom, namely in a 90-minute session in which all students are invited to collaborate in this process. The findings suggest that code reviews in an academic context can help students to strategically reflect about the performed work, enhance their soft skills, and increase their ability to work in groups. On the other hand, as the main challenges, the findings reveal that students typically don’t have previous experience in performing inspections and it can become difficult to perform a complete inspection in a classroom session.

Free Open Source Software in Electronics Engineering Education: A Survey
Статья научная
Since the last two decades, much attention has been paid to Electronics Engineering (EE) education in India. Various commercial software tools and simulator such as mathematical application packages, electronics CAD tools, learning management systems, multimedia tools and general purpose tools supports EE education. Traditionally, proprietary software packages such as OrCAD Pspice, MATLAB, LabView, Multisim and others too are widely practiced and well integrated in electronics engineering curricula of various Universities nationwide. In today’s market, there are plenty of software tools and packages; however, most of them are expensive. The high cost of standard commercial packages is often hardship for students and faculties. Selecting various appropriate tools for academic use is considered as one of the key challenges in EE education. Over recent years, an alternative trend based on Free Open Source Software (FOSS) has gained momentum in higher education due to several benefits such as cost, license management flexibility, access to source code, security and stability etc. Presently, a plethora of open source software tools and resource related to EE can be deployed in teaching and learning process of EE education. In this communication, a short exposition of Free Open Source Software useful in electronics engineering education and research is presented. A brief outlook of FOSS packages, their web addresses and major highlights are also presented. The overall aim of this paper is to create awareness among instructors and students to impart active and self learning using FOSS.

Fuzzy Latent Semantic Query Expansion Model for Enhancing Information Retrieval
Статья научная
One natural and successful technique to have retrieved documents that is relevant to users' intention is by expanding the original query with other words that best capture the goal of users. However, no matter the means implored on the clustered document while expanding the user queries, only a concept driven document clustering technique has better capacity to spawn results with conceptual relevance to the users' goal. Therefore, this research extends the Concept Based Thesaurus Network document clustering techniques by using the Latent Semantic Analysis tool to identify the Best Fit Concept Based Document Cluster in the network. The Fuzzy Latent Semantic Query Expansion Model process achieved a better precision and recall rate values on experimentation and evaluations when compared with some existing information retrieval approaches.

Fuzzy SLIQ Decision Tree Based on Classification Sensitivity
Статья научная
The determination of membership function is fairly critical to fuzzy decision tree induction. Unfortunately, generally used heuristics, such as SLIQ, show the pathological behavior of the attribute tests at split nodes inclining to select a crisp partition. Hence, for induction of binary fuzzy tree, this paper proposes a method depending on the sensitivity degree of attributes to all classes of training examples to determine the transition region of membership function. The method, properly using the pathological characteristic of common heuristics, overcomes drawbacks of G-FDT algorithm proposed by B. Chandra, and it well remedies defects brought on by the pathological behavior. Moreover, the sensitivity degree based algorithm outperforms G-FDT algorithm in respect to classification accuracy.
