It is a process to allow users and developers to elicit required information during requirements gathering before implementation starts. Collaborative application is an example of software that possesses knowledge sharing as the main component needed by users in using the application. RE supports software implementation by identifying requirements specification needed for supporting knowledge sharing. This paper gives an overview of requirements elicitation in collaborative application under the umbrella of RE. Thus, Electronic learning domain will be used as an example of collaborative application in order to give the idea of knowledge sharing among users. Electronic-learning can be seen as a collaboration of entities which comprises students, instructors, administrators, designers and developers of the application. Therefore, the challenges of E-learning are also highlighted in this paper in order to depict the importance of RE process for software development purpose.

Their modularity and smaller size offer flexibility advantageous to both development and operational teams. However, the bigger picture is still lacking despite numerous researches on microservices. There are few aspects of microservices that have never been discussed in depth despite being acknowledged repeatedly. The current research is the continuation of our previous paper, "A systematic mapping on microservices". In the named paper we have identified the focus areas of microservices' researches. Along with our previous findings we have spotted several crucial key points that require further discussions. These includes: definition of microservices, their sizes and boundaries. We have also explored the relationship of microservices with SOA and DDD. These are the two terms that are frequently associated with microservices. Finally, we have discussed DevOps, cloud and virtualization as three of the most essential factors in microservices ecosystem. We attempted to clarify the role of each of these factors. Based on our findings, there is still no standardized definition for microservices to-date. In absence of clear guidelines, SOA and DDD concepts are widely being used to develop microservices. DevOps practices together with the cloud environment are playing an important role in facilitating the implementation of microservices. We have also identified containerization as an effective method to overcome the hardware limitation besides speeding up the delivery process.

Indoor Positioning Systems are needed to provide indoor Location Based Services. Wireless LAN fingerprints are one of the best choices for Indoor Positioning Systems because of their low cost, and high accuracy, however they have many drawbacks: creating radio maps is time consuming, the radio maps will become outdated with any environmental change, different mobile devices read the received signal strength (RSS) differently, and peoples' presence in LOS between access points and mobile device affects the RSS. This research proposes a new Adaptive Indoor Positioning System model (called DIPS) based on: a dynamic radio map generator, RSS certainty technique and peoples' presence effect integration for dynamic and multi-floor environments. Dynamic in our context refers to the effects of people and device heterogeneity. DIPS can achieve 98% and 92% positioning accuracy for floor and room positioning, and it achieves 1.2 m for point positioning error. RSS certainty enhanced the positioning accuracy for floor and room for different mobile devices by 11% and 9%. Then by considering the peoples' presence effect, the error is reduced by 0.2 m. In comparison with other works, DIPS achieves better positioning without extra devices.

There has been no comprehensive study reporting on different project sizes in various domains and in multiple countries. We present our extensive literature survey of critical success factors that impact software projects. Forty-three articles from the years 1990 to 2010 were found to be significant contributions that could be analysed in order to develop a list of critical factors that specifically affect the success of software projects. The method of content analysis and frequency analysis was adopted. Twenty-six critical success factors were found to be related to software project success. We suggest that organisation or project manager is attentive to control the top five critical factors to drive towards project success since the percentage of frequency of occurrences for each is more than 50%. Also, it appears that non-technical factors (94%) dominated over technical factors (6%). In a result unique to our study compared with previous one, we found that the factors of clear and frozen requirements, realistic estimation of the schedule and budget, along with a competent project manager are the five most critical success factors of software projects.
