Android Application Development Based Tourist Guiding Mobile Application Using Java & XML Coding

Mobile applications are extremely popular with many higher education institutions offering courses to prepare new developers sought by the software industry. However, teaching and assessing mobile application development poses specific challenges due to the complexity of real-world programming languages and environments. In this work, we present a script-based approach for teaching and assessing Android application development that addresses shortcomings of existing tools that impact negatively on the learning experience. Our evaluation, which covers pedagogical and technical aspects, provides possible evidence that the scripts have been beneficial in helping students to work more efficiently and achieve better results. Additionally, the scripts have been effective in streamlining the grading process and keeping the tutorial material up to date with the evolution of the Android platform.

Boolean Expressions

Students who are enrolled in computer-related courses need to have a fundamental knowledge and application of Boolean expressions. Learning Boolean algebra and digital logic are somehow difficult for students to grasp especially because these disciplines highly require them of critical thinking and logical understanding. To address this need, the researchers designed and developed a mobile application for Android-enabled phones that will assist the teacher in explaining the concepts of Boolean expressions to students. Developmental-experimental designs of research were used. The data gathered from the respondents were analyzed and utilized in the application development where it accepts Boolean expressions and displays the generated simplified expression, truth table, Karnaugh map, and logic circuit diagrams. The application does not require a network connection and runs only on the Android operating system. The researchers used the following tools in the development of the mobile application: Eclipse as editor, Android Software Development Kit (SDK) as a development tool, and SQLite as its database. The mobile application was tested, evaluated, and used by the respondents. Respondents agreed that the application is better than the manual procedures in simplifying Boolean expressions. Thus, this Android-based application is highly recommended as a tool for teaching Boolean expressions.

Mobile Application Development

A native Android application and a multi-platform web application to monitor solar radiation and the output power of a photovoltaic system were developed, in order to establish which is more efficient using the mobile device resources. The methodology for Mobile Application Development [MAD] was adopted and free software tools –Android Studio and HTML5– were used. CPU consumption, response time in sending data and memory usage for the execution of the applications, were compared; also, the user experience was evaluated through the 6Ms survey. The transfer time of a data from the server to the mobile application executed in Chrome was 0.887 seconds, the native application transfers a data in 0.853 seconds –both times are within the acceptable ranges, since the acquisition system stores one data every 5 minutes; the average memory usage was 182 Mb for executing the application in the Chrome browser, while the native application achieved a reduction of 65%, therefore it can be concluded that the native application requires less memory usage for its execution.

The University

Governments the world over are increasingly challenging universities to produce human resources with the right skills sets and knowledge required to drive their economies in this twenty-first century. It therefore becomes important for universities to produce graduates that bring tangible and meaningful contributions to the economies. Graduate tracer studies are hailed to be one of the ways in which universities can respond and reposition themselves to the actual needs of the industry. It is against this background that this study was conducted to establish the relevance of the Department of Information and Communication Technology at Mzuzu University to the Malawian economy by systematically investigating occupations of its former students after graduating from the University. The study adopted a quantitative design by distributing an online-based questionnaire with predominantly closed-ended questions. The study focused on three key objectives: to identify key employing sectors of ICT graduates, to gauge the relevance of the ICT programme to its former students’ jobs and businesses, and to establish the level of satisfaction of the ICT curriculum from the perspectives of former ICT graduates. The key findings from the study are that the ICT programme is relevant to the industry. However, some respondents were of the view that the curriculum should be strengthened by revising it through an addition of courses such as Mobile Application Development, Machine Learning, Natural Language Processing, Data Mining, and LINUX Administration to keep abreast with the ever-changing ICT trends and job requirements. The study strongly recommends the need for regular reviews of the curriculum so that it is continually responding to and matches the needs of the industry.

BACKGROUND Diligent wear of removable orthodontic retainers requires prolonged compliance and is invariably necessary to preserve optimal results. Patient-informed behaviour-change interventions represent a promising and novel means of enhancing compliance with retainer wear. OBJECTIVE To describe the development of a patient-informed mobile application aimed to enhance retainer wear. METHODS Four aspects were considered during mobile application development: participant preferences; analysis of publicly-available retainer-related posts on Twitter; available interventions; and behaviour-change theories. Audio-recorded one-to-one interviews were conducted with a subset of participants to account for patient preferences in terms of features, design and content. A criterion-based purposive sample of participants wearing vacuum-formed retainers for at least 4 years was used. Thematic analysis of transcribed data was undertaken. RESULTS The need to facilitate communication with the treating clinician, responsive reminder and tracking systems, and access to useful and engaging written and visual information, in addition to other personalised and interactive features were considered important. Concerns related to retainer wear shared on Twitter informed an exhaustive list of frequently-asked questions. Application features were mapped to relevant theoretical constructs. Determinants of existing behavioural change theories were used to link application features to expected outcomes. CONCLUSIONS A holistic process involving both patient and professional input can be useful in informing the development of mobile applications. The orthodontic application (“My Retainers”) will undergo further scrutiny in relation to its effectiveness in inducing behavioural change and concerning patient experiences prior to finalisation.

Abstract To maintain the competitive edge and evaluating the needs of the quality app is in the mobile application market. The user’s feedback on these applications plays an essential role in the mobile application development industry. The rapid growth of web technology gave people an opportunity to interact and express their review, rate and share their feedback about applications. In this paper we have scrapped 506259 of user reviews and applications rate from Google Play Store from 14 different categories. The statistical information was measured in the results using different of common machine learning algorithms such as the Logistic Regression, Random Forest Classifier, and Multinomial Naïve Bayes. Different parameters including the accuracy, precision, recall, and F1 score were used to evaluate Bigram, Trigram, and N-gram, and the statistical result of these algorithms was compared. The analysis of each algorithm, one by one, is performed, and the result has been evaluated. It is concluded that logistic regression is the best algorithm for review analysis of the Google Play Store applications. The results have been checked scientifically, and it is found that the accuracy of the logistic regression algorithm for analyzing different reviews based on three classes, i.e., positive, negative, and neutral.
