Key Process Areas (KPAs) for Software Engineering Institute (SEI) Maturity Level 4 can be described in terms of Quantitative Process Management (QPM) which is the metric to control the quantitative performance of a software project. On the other hand, Software Quality Management (SQM) monitors and controls the quality of the project. The survey conducted in this paper covers around 20 software houses of Pakistan. The study revealed that there is weakness in both KPAs, SQM and QPM. Each KPA defines a set of rules that are necessary to be followed to meet the standard but many organizations fail to follow these rules defined in every KPA. If specified and appropriate measures are taken, the software industry will lift it up to the higher CMMI Level.

Event Stream Processing in BRT Environment
Статья научная
Bus Rapid Transit (BRT) system is a kind of Intelligent Transportation System (ITS), which combines wireless communications, computational technologies, floating car data/floating cellular data technologies, inductive loop detection and so on. The GPS (Global Position System) data and the loop detection data are arriving at the BRT dispatch center massively at the same time so the dispatcher can know the real-time status of buses. The passenger flow data are also captured by devices deployed in the stations and then be passed to center too. How to handle those data at low latency and get some events to be used in bus dispatching is really a problem. In this paper, we propose a framework using ESP (event stream processing) technologies that solves the problem more effectively. At last we demonstrate a prototype system implementation that applies in BRT Line 1 project in Beijing.

Статья научная
Computing as a utility has been possible with cloud computing technology. Another technology that has evolved with the internet and has become an inseparable part of our lives is the internet of things (IoT). With the growing use of IoT devices, the data generated and used by them is increasing tremendously, and resource-constrained IoT devices can make use of the cloud for data and computing needs. When IoT and cloud converge there are security and privacy issues as the cloud is a shared resource. Access control mechanisms play an important role in maintaining the security of users' data. Attribute-based encryption provides fine-grained access to data, thus ensuring selective access to data. We review the literature on access control mechanisms for cloud-based IoT and provide an analysis of their strengths and weaknesses. We present a comparison of the mechanisms, highlighting the challenges and open research questions in the field of cloud-based IoT access control and provide suggestions for future research and development.

This research paper investigates the attitudes and behaviors of Sri Lankan internet users toward passwords and password managers. The study addresses the security flaws and malpractices associated with passwords and aims to identify effective password management solutions. Two surveys were conducted, one focusing on user attitudes and strategies related to passwords, and the other evaluating user experiences with decentralized offline password managers. The findings reveal that a significant portion of the participants employed complex password-creation strategies and utilized various methods for storing and reusing passwords. Male participants and individuals in the 20-29 age group were predominant in the study. Surprisingly, only a minority of participants had received training in password creation and management. The analysis also indicated that participants without training tended to create easily breakable pass-words, while those with training opted for more complex and stronger passwords. In terms of password management methods, participants without training relied on manual note-taking or memorization, while those with training pre-ferred secure password managers. Furthermore, the study found a higher prevalence of password reuse among partici-pants who used manual password creation methods compared to those who used password generators. The research underscores the need for improved password management practices and increased awareness among Sri Lankan internet users. The findings introduce novel insights into the existing knowledge of password management and lay the groundwork for developing targeted interventions and strategies to enhance security in the Sri Lankan online landscape.

The role played by the E-learning system is crucial, especially in the urgent need for working away from the universities and colleges such as on holidays, weekends, and during pandemic situations like COVID-19. Researchers have constantly been producing more sophisticated alternatives for effective usage of E-learning systems and among them include models which explain how users accept, use, and evaluate such systems as they use them on daily basis. Due to the low ICT readiness in developing nations like Tanzania, there is a lack of grounds for the inclusion of various factors and dimensions to the conceptual models which in turn results in testing incomplete, intuitive, and ad hoc sets or irrelevant dimensions. This study closes this gap by conducting a systematic documentary review of studies from 2007 to 2020 on E-learning systems to identify the key factors and their associated dimensions. The findings provide foundations that further research on e-learning acceptance in the contexts of developing countries including Tanzania can adopt on formulating hypotheses and generating information on their research contexts.
