This paper presents an advanced version of a configurable demonstrator platform developed for a new wireless local area network called TUTWLAN. TUTWLAN is targeted for limited service areas with stationary or portable terminals. Applications range from simple wireless sensors to multimedia laptops. The network supports the different Quality of Service (QoS) requirements of these applications. The...
Personalized medicine seems to be a potential solution to the known challenges facing clinical research and drug development. However, the personalized approach requires many new software tools that are able to interact with each other. These applications are often developed by academic groups as part of a research project. To be employed in clinical trials, these tools must undergo a process called...
The article presents basic concepts of GMSK modulation and ways creating signals with GMSK modulation. Special attention in the article is given description of testing receiving equipment of the automatic identification system. The design of the hardware-software complex by MATLAB is described. The correct operation of the hardware-software complex was checked by verified AIS Base Station T214. As...
Test case prioritization is a technique for selecting those test cases, which are expected to outperform for determining faulty modules earlier. Different phases of software development lifecycle represent the total software from different point of views, where priority module may vary from phase to phase. However, information from different phases of software development lifecycle is rarely introduced...
Reservation of adequate food is a major concern for many developing countries worldwide. Governments of those countries also want to meet the demand of food in the long term, especially during the period of natural calamity. For low lying region such as Bangladesh, predicting the supply of food is critical. Besides, rice productivity of Bangladesh has also changed due to varying climatic over the...
A number of efforts have been applied on human activity recognition such as face recognition and motion analysis. The major problems in recognition are: 1. Scale. 2. Shift. 3. Projection. Human Activities are identified by the pose of the body such as standing, sitting etc. and some of the activities are like the emotions, facial expressions etc. Generally, human activity recognition is achieved by...
Mobile devices are gradually taking over traditional computers' dominance in human lives. With the ever-increasing shipment of mobile apps running on these devices, their quality issues become a severe challenge. Although automated testing techniques are being widely studied, they mostly fall short of handling mobile apps' complex interactions, e.g., A finger swipe or device shaking gesture, leading...
Reforms in the educational system emphasize more on continuous assessment. The descriptive examination question paper when compared to objective question paper acts as a better aid in continuous assessment for testing the progress of a student under various cognitive levels at different stages of learning. Unfortunately, assessment of descriptive answers is found to be tedious and time consuming by...
To improve the shortage of the existing online examination system, a common online curriculum examination system is designed and realized. Mainly from the system function design, database design and security mechanisms design, the paper elaborates the implementation of the system. Many courses and a variety of questions can be taken into account by the system, and also flexible and comprehensive exam...
Take-A-Break Notification is a software which runs on Windows operating system designed for office workers who have the highest tendency on prolonged computer screens use, in order to reduce Computer Vision Syndrome (CVS). The purpose of this study is to prevent computer users from looking in front of a computer screen for a long period of time. Rapid Application Development (RAD) methodology has...
This research aims to let people know their hierarchy of prolonged distractions starting from the most distracting to the least distracting factors while driving a car. In order to do this, an HTML5 game that simulated a car drive with numerous distractions, which include both audio and visual distractions, was created. The player of the game needs to wear an EEG device, Neurosky, for his or her Beta...
This paper proposes a method for simulating human opinions about graphical artistic expressions like calligraphy using computers. Scanned images of handwriting texts from a large database are labeled as "beautiful writing" or "ugly writing" by two persons based on their own likes. Our objective is to replicate these opinions using machine learning techniques. Shape features are...
Introducing an external user in the capstone design course can be beneficial for the students, but also brings several challenges. The user, who takes on the part of a customer that wishes to take possession of and use the designed product, helps ensure that the project is relevant, usable and within budget and timeline. He or she participates in setting specifications for the product and modifying...
As part of the ongoing Responsive AUV Localization and Mapping project (REALM) Memorial University has been developing an autonomous path localization and following system. This Qualitative Navigation System (QNS) localizes an AUV to a predefined path and generates control inputs to maintain the AUV along that path without the need for an absolute position estimate. QNS processes sonar data into the...
Imbalanced data-set Classification has become a hotspot problem in Data Mining. The essential assumption of the traditional classification algorithms is that the distribution of the classes is balanced, therefore the algorithms used in Imbalanced data-set Classification cannot achieve an ideal effect. In view of imbalance date-set classification, we propose an over sampling method based on support...
The aim of this paper is to propose a reliable and efficient solution for detecting and correcting errors in communication channels. The implementation method of Hamming decoder is the first error correction code used in computers. We used a Spartan 3 reconfigurable circuit because this board is fully compatible with all versions of the Xilinx ISE tools, including the free WebPack. We studied linear...
Attackers regularly evaluate anti-malware software to see whether or not their malware will be detected. This attacker-driven anti-malware testing is something defenders would ideally want to limit. Given that anti-malware products must be widely distributed to be commercially viable, it is not feasible to prevent attackers from running them. Here we examine whether it may be possible to instead limit...
The general purpose Automatic Test System included the general purpose instruments and the special purpose Test Unit Adapter (TUA). With the increasing types of the unit under test, the number of the TUA was increasing too, eventually leading to huge automatic test system. The main idea of this research is removing TUA and connecting the instrument and the equipment under test directly. So the volume...
A plurality of emulated systems is used to create a realistic virtual training environment. Retaining an open architecture allows emulator components to be swapped with physical hardware to create a more expansive variety of virtual training and test environments, as well as to abstract the user from the underlying hardware emulation. This allows for the creation of a low cost training environment...
UAV ground testing system (referred to as: testing system) not only lacks of universality and scalability, also incapable of handling faculties during flying procedure. By using the new generation of automatic test system, LXI(LAN based eXtensions for Instrumentation), the flight simulation method and fault diagnosis technology, it achieves the purpose of expanding the testing system from ground to...
