E-Citrus: A Cloud-Based Citrus Pest and Disease Detection, Diagnostic and Prevention using Convolutional Neural Network

Citrus fruit yields in the Philippines have been fluctuating dramatically in recent years. Diseases, pests, and soil inadequacy have all contributed to the citrus industry's severe decline. More than 15 viruses and virus-like diseases have infected Citrus. Agricultural productivity must improve for a country to be progressive. Resources should be utilized to their full potential, diseases and pests should be controlled efficiently, and technological advancements must be adopted. This application will identify and map common pests and diseases of citrus fruits in Oriental Mindoro, apply image processing techniques to analyze diseases of citrus fruits with corresponding solutions caused by bacteria, and give information about diseases related to citrus fruits and how to cure them. The researchers used the Spiral Model as a Software Development Life Cycle (SDLC) model to develop this application. In this model, researchers can plan the flow of the application. If the application did not meet the desired result, the researchers could revise it again until it met the desired one. The researchers used the convolutional neural network to classify and process the captured images of the citrus fruits’ diseases and pests. The researchers asked the selected Citrus farmers in Oriental Mindoro to evaluate the project using the different ISO 25010 criteria and rated the application as very acceptable overall.

Agile methodologies between software development and music production: an empirical study

Over the past 20 years agile methodologies revolutionized Information Technology, offering tremendous opportunities for the development of Software Engineering as an independent discipline. More specifically, agile methodologies contributed to enhancing the effectiveness and the speed of the production process as well as to improving the productivity and motivations of software developers organized in high performing teams. The agile philosophy can be and has been applied in different contexts and across several domains. This work analyses the relationship between Agile methodologies used by software engineers and the practices pursued by musicians in their daily lives. Our findings suggests that collaborative, strongly planned software development life cycle models (such as Waterfall, V-model, iterative, and Spiral) are not adequate models to describe the daily practices of musical composers. This is because their work requires a lot of flexibility, which such models intrinsically lack, because they are oriented to ensuring some form of monitorable progress. Interestingly, our findings also show that nine out of 12 Agile Principles are consciously or unconsciously followed by musicians in their practices. This suggests that there are some deep connections between these twoprima faciedifferent fields, which are both very creative. Even though our findings await replication, possibly with larger statistical samples, they contribute to open up a new strand of research in the field.

Design and Programming for Multicore machines: An Empirical study on time and effort required by programmer

As the demand for high-performance computing continues to surge, harnessing the full potential of multicore architectures has become paramount. This paper explores a pragmatic approach to transition from sequential to parallel programming, capitalizing on the computational prowess of modern hardware systems. Recognizing the challenges of enforcing parallelism in early software development phases, we advocate for a focus on the implementation stage, where architects, designers, and developers can seamlessly introduce parallel constructs while preserving software integrity. To facilitate this paradigm shift, we introduce the “SDLC model with Parallel Constructs,” a modified Software Development Life Cycle (SDLC) framework comprising additional phases: “Parallel Constructs” and “Test Parallel Constructs.” This model empowers development teams to integrate parallel computing efficiently, enhancing performance and maintaining a structured development process. Our observations reveal intriguing dynamics. Initially, the single-threaded program outperforms its parallel counterpart for smaller datasets, but as data sizes grow, the parallel version demonstrates superior performance. We underscore the pivotal role of available CPU cores and task partitioning in determining efficiency. Our analysis also evaluates the programmer’s effort, measured by lines of code, needed for the transition. Leveraging OpenMP constructs streamlines this transition, reducing programming complexity.

Impact of software development processes on the outcomes of student computing projects: A tale of two universities

Project-based courses are more and more commonly used as an opportunity to teach students structured methods of developing software. Two well-known approaches in this area – traditional and Agile – have been successfully applied to drive academic projects. However too often the default is still to have no organizational process at all. While a large variety of software development life-cycle models exists, little guidance is available on which one to choose to fit the context of working with students. This paper assesses the impact of iterative, sequential and “hands-off” development approaches on the success of student computing projects. A structured, metric-based assessment scheme was applied to investigate team productivity, teamwork and the quality of the final product. Empirical evidence was collected during a controlled experiment carried out at two engineering schools in Europe. More than 100 students at Bachelor’s and Master’s levels participated in the research, with varied software development and teamwork skill sets. Similar patterns were observed among both sets of subjects, with iterative teams demonstrating the highest productivity and superior team cohesion but a decline in the quality of the final product. Sequential development led to a considerable improvement in the external quality characteristics of the software produced, owing to the method’s stress on design activities. The findings of this study will be of use to educators interested in applying software development processes to student groupwork. A set of guidelines is provided for applying a structured way of working in a project-based course.

Formalization of the prediction and ranking of software development life cycle models

The study of software engineering professional practices includes the use of the formal methodology in a software development. Identifying the appropriate methodology will not only reduce the failure of software but will also help to deliver the software in accordance with the predetermined budget and schedule. In literature, few works have been developed a tool for prediction of the most appropriate methodology for the specific software project. In this paper, a method for selecting an appropriate software development life cycle (SDLC) model based on a ranking manner from the highest to the lowest scoring is presented. The selection and ranking of appropriate SDLC elaborate the related SDLC’s critical factors, these factors are given different weights according to the SDLC, then these weights are used by the proposed mathematical method. The proposed approach has been extensively experimented on a dataset by software practitioners who are working in the software industry. Experimental results show that, the proposed method represents an applicable tool in predicting and ranking suitable SDLC models on various types of projects, such as: life-critical systems, commercial uses systems, and entertainment applications.

CHARACTERIZING SOFTWARE QUALITY ASSURANCE PRACTICES IN KENYA

Given the increased reliance on technology, Software Quality Assurance(SQA) has become a vital area in Software Engineering (SE). SQA practices require training, cost and often take more time than actual code writing. Owing to these requirements, software developers often ignore or partly implement SQA practices, leading to potentially poor quality software development. The goal of the study is to characterise SQA practices of software developers in Kenya. As such, quantitative empirical research was conducted. Seventy-seven (N=77) completed questionnaires were received and analysed to yield the required insights. The analysis of the findings indicates compliance with SQA practices. However, the research unearths concerns such as failure to comply with Software Development Life Cycle (SDLC) models as having the potential to lower the quality of software products. The assessment found that Unit testing was the most common type of software test. Based on the findings and literature, recommendations are made. The need to improve software engineering education and invest in software testing is underscored. The results can be generalised to most developing countries and used by software developers and trainers to identify areas in SQA that need strengthening.
