An Integrated Three-Flow Approach For Front-End Service Composition, Lim Mei Ting
An Integrated Three-Flow Approach For Front-End Service Composition, Lim Mei Ting
Student Works (2020-2029)
End-User Service Composition (EUSC) aims to enable end-user programmers who are not professional developers, develop applications by composing or aggregating existing web services. Despite the effort, studies have shown that end-user programmers are not able to deal with the technical complexities involved in EUSC. One way to deal with this issue is Front-End Service Composition (FESC), which allows end-user programmers to compose web services at the presentation layer of an application by configuring User Interface (UI) widgets that represent the back-end web services. However, apart from there not being enough studies on FESC, end-user programmers also experience a number of …

A Supporting Tool For Requirements Prioritization Process In Agile Software Development, Ramdan Mowad, Khaled Abdelazim Muhammad, Essam Elfakharany
Future Computing and Informatics Journal
Requirements engineering is a crucial phase of software engineering, and requirements prioritization is an essential stage of requirements engineering particularly in agile software development. Requirements prioritization goals at eliciting which requirements of software need to be covered in a particular release. The key point is which requirement will be selected in the next iteration and which one will be delayed to other iterations for minimizing risk during development and meeting stakeholders’ needs. There are many existing techniques for requirement prioritization, but most of these techniques do not cover continuous growth, change of requirements, and requirements dependencies. The prioritization techniques need …

Bulletin of TUIT: Management and Communication Technologies
Formalization approaches of user interface design (UID) in conjunction with model driven techniques aim to improve the usability in terms of conformity to standards or style guides and to leverage code generation of interactive software systems, so that various UI platforms for web, desktop or mobile Applications are supported. Because large parts of the UI are described platform independent instead of platform dependent implementations, re-usability of the UI concept is also improved. However, UI formalization requires the usage of a formal UI description language and a higher level of abstractness compared to concrete UI code. These languages need to be …

Efficient End-To-End Autonomous Driving, Hesham Eraqi
Theses and Dissertations
Steering a car through traffic is a complex task that is difficult to cast into algorithms. Therefore, researchers turn to train artificial neural networks from front-facing camera data stream along with the associated steering angles. Nevertheless, most existing solutions consider only the visual camera frames as input, thus ignoring the temporal relationship between frames. In this work, we propose a Convolution Long Short-Term Memory Recurrent Neural Network (C-LSTM), which is end-to-end trainable, to learn both visual and dynamic temporal dependencies of driving. Additionally, We introduce posing the steering angle regression problem as classification while imposing a spatial relationship between the …

Monetary Impact Of National Exchange Carrier Association Tariffs On Internet Access Cost In Rural Areas, Tim Obermier, Angela K. Hollman
Mountain Plains Journal of Business and Technology
This study examines the monetary impact of tariffs on consumer internet access via a digital subscriber line (DSL). Historically, the Communications Act of 1934 mandated that telephony services be provided to everyone, without exclusion. With the rapid emergence of the internet, the Connect America Fund was recently implemented to ensure equal access to both voice and broadband services. Since many telephony companies have emerged as internet service providers, DSL internet service is often bundled together with a landline telephone, especially in rural areas. This study examines the total cost of such bundled DSL internet service across the classes of cities …
