Ajax-enabled web applications are a new breed of highly interactive, highly dynamic web applications. Although Ajax allows developers to create rich web applications, Ajax applications can be difficult to comprehend and thus to maintain. For this reason, we have created FireDetective, a tool that uses dynamic analysis at both the client (browser) and server side to facilitate the understanding of Ajax applications. Using an exploratory pre-experimental user study, we see that web developers encounter problems when understanding Ajax applications. We also find preliminary evidence that the FireDetective tool allows web developers to understand Ajax applications more effectively, more efficiently and with more confidence*. © 2010 IEEE.

This paper extends an initial investigation of eHealth from the developers’ perspective. In this extension, our focus is on mobile health data. Despite the significant potential of this development area, few studies try to understand the challenges faced by these professionals. This perspective is relevant to identify the most used technologies and future perspectives for research investigation. Using a KDD-based process, this work analyzed eHealth and mHealth discussions from Stack Overflow (SO) to comprehend this developers’ community. We got and processed 6082 eHealth and 1832 mHealth questions. The most discussed topics include manipulating medical images, electronic health records with the HL7 standard, and frameworks to support mobile health (mHealth) development. Concerning the challenges faced by these developers, there is a lack of understanding of the DICOM and HL7 standards, the absence of data repositories for testing, and the monitoring of health data in the background using mobile and wearable devices. Our results also indicate that discussions have grown mainly on mHealth, primarily due to monitoring health data through wearables and about how to optimize resource consumption during health-monitoring. © 2023, The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd.

Anomaly detection is an important challenge for tasks such as fault diagnosis and intrusion detection in energy constrained wireless sensor networks. A key problem is how to minimise the communication overhead in the network while performing in-network computation when detecting anomalies. Our approach to this problem is based on a formulation that uses distributed, one-class quarter-sphere support vector machines to identify anomalous measurements in the data. We demonstrate using sensor data from the Great Duck Island Project that our distributed approach is energy efficient in terms of communication overhead while achieving comparable accuracy to a centralised scheme.

Despite all efforts to support processes through IT, processes based on paper forms are still prevalent. In this paper, we propose a costeffective and non-technical approach to automate form-based processes. The approach builds on several types of annotations: to help collect and distribute information for form fields;to choose appropriate process execution paths;and to support email distribution or approval for filled forms. We implemented the approach in a prototype, called EzyForms. We conducted a user study with 15 participants, showing that people with little technical background were able to automate the existing formbased processes efficiently. © Springer-Verlag Berlin Heidelberg 2012.

This study investigated the characteristics of data clumps in UML class diagrams. Data clumps are group of variables which appear together in multiple locations. In this study we compared the data clumps characteristics in UML class diagrams with them of source code projects. By analyzing the extensive Lindholmen and GenMyModel datasets, known for their real–world applicability, diversity, and containing more than 100,000 class diagrams in total, significant differences in the distribution and nature of data clumps were revealed. Approximately 19 % of the analyzed class diagrams contained data clumps. It was observed that field–field data clumps predominated in UML class diagrams, particularly in the GenMyModel dataset, while parameter–parameter data clumps were less frequent. Moreover, in contrast to the distribution in source code projects, data clumps in UML class diagrams were typically distributed across multiple classes or interfaces, forming larger chains. parameter–parameter data clumps were predominant in source code projects, indicating more detailed implementation of methods in these projects. These findings reflect different modeling approaches and paradigms among the respective user groups. This study has provided important insights regarding the development of UML modeling tools, teaching methods, and design practices in software development. © 2024 by SCITEPRESS – Science and Technology Publications, Lda.

Multi Radio Multi Channel Wireless Mesh networks (MRMC-WMNs) are undergoing rapid progress and inspiring numerous deployments. These networks require carefully assignment of resources and load balancing to provide the quality guarantees to traffic flows. Load balancing avoids the creation of bottlenecks and increases the network efficiency. Certainly, we need a benchmark to compare the performance of different load balancing mechanisms. In this paper, we consider the scenario of bandwidth-guaranteed broadcast sessions, where each session has a specific bandwidth requirement. The aim of this research is to analyze the performance of broadcasting in small-scale MRMC-WMNs. By considering Wireless Broadcast Advantage (WBA), we formulate channel and node constraints and propose Traffic engineering Efficiency to evaluate the load balancing ability of algorithms. Deriving analytical relationships between throughput, number of transmissions, node and channel utilization is other contribution of this paper. In order to confirm the accuracy of derived analysis, we present some simulations on typical networks. © 2012 GIRI.

Spanning Tree Protocol (STP) is an approved standard protocol that provides a tree forwarding topology in Ethernet networks. Tree topology ensures a unique path from any node to every other node in the network. One of the main disadvantages of STP is its poor load balancing capabilities that results in uneven load distribution and bottlenecks. In our previous work, we have suggested Shortcut Switching Strategy (SSS) to overcome this problem. SSS improves load balancing by using some blocked links to forward traffic. In this paper, we propose a novel forwarding strategy named Enhanced Forwarding Strategy (EFS) that enhances the performance of SSS. Simulation results show that this new strategy decreases the traffic load on links and switches and has a good load balancing performance. © 2012 GIRI.

Background: History based regression testing was proposed as a basis for automating regression test selection, for the purpose of improving transparency and test efficiency, at the function test level in a large scale software development organization. Aim: The study aims at investigating the current manual regression testing process as well as adopting, implementing and evaluating the effect of the proposed method. Method: A case study was launched including: identification of important factors for prioritization and selection of test cases, implementation of the method, and a quantitative and qualitative evaluation. Results: 10 different factors, of which two are history-based, are identified as important for selection. Most of the information needed is available in the test management and error reporting systems while some is embedded in the process. Transparency is increased through a semi-automated method. Our quantitative evaluation indicates a possibility to improve efficiency, while the qualitative evaluation supports the general principles of history-based testing but suggests changes in implementation details. © 2011 IEEE.

The disaggregated architecture of advanced Radio Access networks (RANs) with diverse X-haul latencies, in conjunction with resource-limited multi-access edge computing networks, presents significant challenges in designing a general model in placing baseband and user plane functions to accommodate versatile 5G services. This paper proposes a novel approach, NetMind+, which leverages Deep Reinforcement Learning (DRL) to determine the function placement strategies in diverse and evolving RAN topologies, aiming at minimizing power consumption. NetMind+ resolves the problem with a maze-solving strategy, enabling a Markov Decision Process with standardized action space scales across different networks. Additionally, a Graph Convolutional Network (GCN) based encoding and an incremental learning mechanism are introduced, allowing features from different and dynamic networks to be aggregated into a single DRL agent. This facilitates the generalization capability of DRL and minimizes the negative retraining impact. In an example with three sub-networks, NetMind+ demonstrates a substantial 32.76% improvement in power savings and a 41.67% increase in service stability compared to benchmarks from the existing literature. Compared to traditional methods necessitating a dedicated DRL agent for each network, NetMind+ attains comparable performance with 70% of the training cost savings. Furthermore, it demonstrates robust adaptability during network variations, accelerating training speed by 50%. © 2004-2012 IEEE.

Wireless networks have contributed to the technological advance that popularized the use of mobile devices, and fostered the development of applications targeted to these devices. However, issues such as mobility and communication intermittency, as well as processing, storage and battery constraints demand changes in the traditional software testing process. This paper aims to present testing requirements that are specific to applications developed for mobile devices. We also show that these requirements can improve productivity and efficacy in the testing process of an application.
