Determination of reproduction accuracy of dot area of irregular structure
Статья научная
The paper deals with the analysis and calculation of the impact of raster element structure on the reproduction accuracy of the area. The process of screening is one of the important stages of preparing images for printing. Depending on the method of forming of an area of a printing element are distinguished: continuous, which is conventionally called analog screening, and screening with their discrete variables - digital screening. Digital screening systems are widely used in computer publishing systems. In the digital screening of forming shape and sizes of raster elements carried out discrete using raster image processor (RIP). A well-known fact is that the value of the dot area is a key information-bearing parameter of discrete screening since reproduction of halftone key in a raster image is carried out by changing the dot area. It is therefore an important and relevant task to determine the dot area.

Development and Evaluation of Mobile Telenursing System for Drug Administration
Статья научная
Mobile telenursing is an emerging sub-field of mobile health that proposes remote nursing care provision with the aim of reducing stress on nurses by enabling them to spend more time on direct patient care rather than indirect care. Most existing mobile telenursing systems are limited to a simple phone call and Short Message Service (SMS) alert thereby rendering them inadequate to support indirect patient cares such as remote prescription based on consultant’s advice and monitoring of drug usage adherence. Hence, this research developed a Mobile Telenursing and Drug Administration System (MTS) characterized by support for the aforementioned indirect patient cares. Domain-Driven Design was employed in designing MTS client-server architecture and its framework. The framework was implemented by developing an SMS reminder system and client mobile application which maintains real-time communication with the webserver. The MTS, which supports real-time consultation between nurse-patient and nurse-consultant, was developed for mobile devices running the Android operating system using the framework implemented. The MTS was programmed using JavaScript and Pusher real-time messaging library of the Android development Kits. The performance of the MTS was evaluated through users’ assessment by administering a set of questionnaire on purposively selected 64 nurses; 53 patients chosen from four (4) purposively selected hospitals (General Hospital, New Bussa; Bowen University Teaching Hospital, Ogbomoso; Alimosho General Hospital, Lagos and Ifako-Ijaiye General Hospital, Lagos). The responses obtained from the questionnaires were statistically evaluated to determine MTS suitability for drug usage monitoring, remote prescription, palliative care, injection administration, patients’ clean-up and follow-up treatment using a correlation test. Also, mean effectiveness and mean acceptability of MTS were evaluated using a t-test at 0.05 level of significance. The MTS was deployed on mobile devices running the Android operating system. The results of performance evaluation revealed that MTS recorded suitability values of drug usage monitoring (r = 0.656), remote prescription (r = 0.829), palliative care (r = 0.925), injection administration (r = -0.772), patients’ clean-up (r = -0.841) and follow-up treatment (r = 0.868) of patients at (p < 0.05). Similarly, MTS recorded mean effectiveness and acceptability values of 3.596 and 3.32, 3.770 and 3.36 at (p < 0.05) for nurses and patients, respectively. The research developed MTS which is suitable for the provisioning of remote nursing care and drug administration without breaking basic medical ethics. The system can be adopted for mobile telenursing and drug administration system.

Appraisal of lecturers’ effectiveness on teaching performance is an administrative duty of educational administrators which is intended to ascertain whether or not lecturers are performing their duty adequately. Most existing appraisal systems (especially in Nigeria) are superior based thus preventing the students that are direct recipients of lecturers’ output to evaluate the teaching competencies of their lecturers. Also, appraisal results that are students’ based are reported questionable in terms of its validity and reliability as the outcome of the evaluation reported biased assessment due to lecturers’ coercion of students into giving falsified evaluation reports or intentional falsification of judgements about a lecturer by sets of students. This study developed a system for students’ appraisal on teaching performance of lecturers (SATP) characterised by support for reduction of students’ partiality and prejudice during appraisal on lecturers’ effectiveness. Domain Driven Design was employed in designing the SATP client-server architecture and its framework. The SATP was programmed using HTML, CSS, JavaScript and PHP. Afterwards, 60 students were allowed to use the system to evaluate 6 lecturers in computer science department, Federal College of Wildlife Management which serves as the purposively selected research domain. The evaluation data obtained from the system were statistically evaluated to determine SATP performance (suitability, effectiveness and ability to detect falsified evaluation) using t-test at 0.10 level of significance. The results of performance evaluation revealed that SATP was found to be visually suitable and effective for lecturers’ evaluation. More so, evaluation data reported as not been falsified by SATP also recorded insignificant differences (∆μ = 0.36, p>0.10) in first and second evaluation while evaluation data reported as been falsified by SATP recorded significant differences (∆μ = 12.22, p<0.10) in first and second appraisal (evaluation). The study concluded that the result of evaluation of lecturers retrieved from the developed SATP is valid and recommend the adoption of the system in tertiary institutions as it will improve the excellence of educators and academics in tertiary institutions.

Development of a hybridized diversity combiner over nakagami fading channel
Статья научная
Wireless communication system is of paramount importance in the world of telecommunication infrastructure and is expected to be a leading role in the development of a nation. However, the system is characterized by multipath propagation effects that lead to variability of the received signal thereby degrading the performance. Equal Gain Combiner (EGC) being used to address this problem is associated with hardware complexity that results in long processing time, while Threshold Combiner (TC) with low processing time has poor performance. Hence, in this paper, a hybridized Diversity Combiner (DC) consisting of EGC and TC, (TC-EGC) with a closed form expression over Nakagami fading channel is developed. TC-EGC is derived using the conventional EGC and TC at the receiver. Randomly generated bits used as source data are modulated using M-ary Quadrature Amplitude Modulation (M-QAM) and transmitted over Nakagami channel after filtering. The faded signals generated at varying paths ‘L’ (2, 3, 4) are scanned by TC to select the strongest paths. The outputs from the three TCs are combined by EGC to obtain the received signal which is converted to baseband through demodulation. A mathematical expression using the Probability Density Function (PDF) of Nakagami fading channel at varying paths ‘L’ for Outage Probability (OP) is also derived. The technique is simulated using Matrix Laboratory (version 7.2). The performance is evaluated using Signal-to-Noise Ratio (SNR), Outage Probability (OP) and Processing Time (PT). The study shows that the TC-EGC gives lower OP and PT values when compared with conventional EGC and TC, with reduction in hardware complexity. The TC-EGC developed can be used to enhance the performance of wireless communication system.

Nowadays, Diabetes is one of the most common and severe diseases in Bangladesh as well as all over the world. It is not only harmful to the blood but also causes different kinds of diseases like blindness, renal disease, kidney problem, heart diseases etc. that causes a lot of death per year. So, it badly needs to develop a system that can effectively diagnose the diabetes patients using medical details. We propose a strategy for the diagnosis of diabetes using deep neural network by training its attributes in five and ten-fold cross-validation fashion. The Pima Indian Diabetes (PID) data set is retrieved from the UCI machine learning repository database. The results on PID dataset demonstrate that deep learning approach design an auspicious system for the prediction of diabetes with prediction accuracy of 98.35%, F1 score of 98, and MCC of 97 for five-fold cross-validation. Additionally, accuracy of 97.11%, sensitivity of 96.25%, and specificity of 98.80% are obtained for ten-fold cross-validation.

Diagnostic Path-Oriented Test Data Generation by Hyper Cuboids
Статья научная
One of the ways of test data generation is using the path-oriented (path-wise) test data generator. This generator takes the program code and test adequacy criteria as input and generates the test data in order to satisfy the adequacy criteria. One of the problems of this generator in test data generation is the lack of attention to generating the diagnostic test data. In this paper a new approach has been proposed for path-oriented test data generation and by utilizing it, test data is generated automatically realizing the goal of discovering more important errors in the least amount of time. Since that some of the instructions of any programming language are more error-prone, so the paths that contain these instructions are selected for perform test data generation process. Then, the input domains of these paths variables are divided by a divide-and-conquer algorithm to the subdomains. A set of different subdomains is called hypercuboids, and test data will be generated by these hypercuboids. We apply our method in some programs, and compare it with some previous methods. Experimental results show proposed approach outperforms same previous approaches.
