Agile practices are release planning, sprint planning, and standup meetings. The Agile provides the requisite time and space for teams, enabling them, to collaborate with each other and build relationship among them. Frequent short meetings are being held daily by Agile teams to identify potential collaboration opportunities to be followed. User Centered Design (UCD) is a user interface design process which lays great emphasis on the usability objectives, user features, environmental circumstances, tasks and work input/flow in the design/model of an interface. However, some challenges occurred when the UCD joins the Agile process such as usability issues, collaboration problems, usability testing etc. The proposed model not only embraces the relevant issues but it resolves the same to a great extent. The evaluation of said model is done through a case study. 2018-01-01T00:00:00Z http://dr.lib.sjp.ac.lk/handle/123456789/11020 An Expert System to Simplify the Management of Human Resources Mobility Said, T.; Otman, A.; Jaafar, A. The management of human resources mobility under constraints within a multiple-sites enterprise can be treated as a complex assignment problem, since we have already formulated and resolved this complex problem by using the genetic algorithm as presented in our previous papers [1] and [2]. In this current paper, we propose an expert system uses a new method to treat a simplified problem without considering the hard constraints. These methods are based of virtual (factious) post addition and employees’ circular permutation modeled by a directed cyclic graph. The aim of this system is also to reduce the number of operations resulting in a significant reduction of execution time and to improve rate mobility of human resources. 2018-01-01T00:00:00Z http://dr.lib.sjp.ac.lk/handle/123456789/11019 Back-Navigation String Matching Algorithm (BSMA) Daniel, M.; Adiela Samuel, R.; Oriji Ikechi, B. This research took a comparative analysis on string matching algorithms. The study focused on developing an efficient algorithm (Back-navigation String matching algorithm) which will be used for large documents. The algorithm whilst compared to the existing system introduced a pattern of search which was done backwardly, from the last character to the first. The existing system considered more number of shifts which was slow and has a bad character shift. The research aimed at developing an efficient string matching for large documents sorting. The research methodology adopted for this project research is the verification and validation methodology which perform its test in a reverse manner so the software developer can at each stage review its step. The proposed system was executed and produced a result which compared with the existing system was termed efficiency. The system introduces a faster means of searching which starts form the last character to the first. The developed system which is the efficient string matching algorithm was analyzed and displayed a faster means of searching documents and is termed efficient because of its computing speed of 2 milliseconds while the naïve algorithm which ran with the computing speed of 154 milliseconds for a total number of 5000 characters. 2018-01-01T00:00:00Z
