Published: August 2020

Aquatic insects are species of significant importance to water bodies because they serve various purposes including nutrient cycling, vectors of pathogens and bioindicators of water quality. Analyzing their community structure is a veritable tool in studies of biodiversity and quality of limnetic ecosystems. Therefore, we investigaTed the health status of a pond in Benin City, Nigeria using insect’s abundance, composition, distribution and physicochemical parameters of the waterbody. Insects were sampled using sweep nets and identified to the species level while water samples were collected and analyzed using in-situ and ex-situ methods to determine the physicochemical properties in three sampling stations. The results of the physicochemical assessment of the water indicated that conditions did not differ widely between sites (P > 0.05) except for total alkalinity, and the recorded values were well within the ambient FMEnv permissible limits for surface water except for dissolved oxygen,turbidity and phosphate. A total of 10 insect taxa, comprising of 103 individuals in 2 orders were recorded in the study and among the orders, Hemiptera comprised of 7 species and Coleoptera comprised of 3 species. Majority of the insect fauna found in this study are typically found in similar water bodies in the tropics. However, the obsereved insect community structure revealed a relatively low taxa richness with a dominance of pollution-resistant species which suggests a moderately polluted condition of the waterbody.

Published: August 2020

In this paper, we formulated, designed, implemented and evaluated a model used for classifying stakeholders' requirements that are specified for web application development. The study employed both qualitative and quantitative research approaches in a case study. Requirements were elicited from stakeholders using the interview approach. This involved speaking with the stakeholders directly via groupware and asking them questions about their specific needs that are relevant to the development of web application. In particular, 10 customers of Procrea8 Technology Solution Limited and 9 developers were used as respondents. An interactive genetic algorithm was used to formulate the model. The design was specified using the Unified Modeling Language (UML) tool, and implemented using specified web technology tools. The model was evaluated for completeness and consistency using recall and precision as parameters. The results showed that a list of ordered requirements was produced based on the stakeholders' priorities inputted into the model. The output indicated the order of priorities finally assigned to each of the requirements. The evaluation revealed that the model is effective, efficient, userfriendly, reliable (with 96.3% accuracy), scalable (prioritized over 500 requirements), less timeconsuming (prioritizing over 500 requirements) and able to update ranks whenever changes occur automatically. Also, the model evaluation indicates 97.1% precision (consistency), and 96.0% recall (completeness). The study shows that requirements engineers could use the model to collate stakeholders’ requirements from wide geographical locations.

Published: August 2020

Chats are bound to be an efficient way of disseminating synchronous and asynchronous information through textual messages or video communication among various people over a network. An Integrated Development Environment (IDE), is a text editor that allows developers and engineers to enhance the different features of writing executable software. Using IDEs, the programmer’s productivity is enhanced by consolidating common activities involved in writing computer programs into a single application. These activities include source code editing, auto-completing, syntax highlighting, building executable, debugging, and automated testing. Python is a programming language used to develop mostly sophisticated Machine Learning and web applications. An IDE makes coding in Python much easier and efficient. It consists of features like indentation and code folding which are very important aspects in executing Python programs successfully. Also, unresolved imports or undefined methods are indicated with warnings and error signs to give programmers more information on impending problems. A web-based Python Integrated Development Environment (IDE) was developed by applying modern communication techniques of text and video chats. This software delivers facilities to programmers for efficient development of programs. It also consists of auto-completion, code fixing, code editing, management and automated testing. A cloud-based IDE was deployed because it enables programmers to easily access their projects anywhere and at any time. Also, hardware limitation issues are eliminated with no setups and configurations required, as all the information is to be stored in the cloud. Hypertext Markup Language, Javascript, and Bootstrap Cascading Style Sheet were used to design the front-end interface, while Asynchronous Javascript, and Extensible Markup Language, Hypertext Pre-processor and My Structure Query Language were employed for the back-end design. Various users can be able to write, edit, debug, run, and store the codes on the server. The user can also use the IDE on any internet-enabled devices such as personal computers, mobile devices, and tablets.

Enhancing Computational Time of Lempel-Ziv-Welch-Based Text Compression with Chinese Remainder Theorem.
Authors: Ibrahim MB , Gbolagade KA 
Published: August 2020

The science and art of data compression is presenting information in a compact form. This compact representation of information is generated by recognizing the use of structures that exist in the data. The Lempel-Ziv-Welch (LZW) algorithm is known to be one of the best compressors of text which achieve a high degree of compression. This is possible for text files with lots of redundancies. Thus, the greater the redundancies, the greater the compression achieved. In this paper, the LZW algorithm is further enhanced to achieve a higher degree of compression without compromising its performances through the introduction of an algorithm, called Chinese Remainder Theorem (CRT), is presented. Compression Time and Compression Ratio was used for performance metrics. Simulations was carried out using MATLAB for five (5) text files (of varying sizes) in determining the efficiency of the proposed CRT-LZW technique. This new technique has opened a new development of increasing the speed of compressing data than the traditional LZW. The results show that the CRT-LZW performs better than LZW in terms of computational time by 0.12s to 15.15s, while the compression ratio remains same with 2.56% respectively. The proposed compression time also performed better than some investigative papers implementing LZW-RNS by 0.12s to 2.86s and another by 0.12s to 0.14s.
