Detection of Infeasible Paths in Software Testing using UML Application to Gold Vending Machine
Статья научная
Software testing is an integral part of the software development cycle. Software testing involves designing a set of test cases. In white box testing, test cases are usually designed based using path testing. The basis path testing approach involves generation of test cases from a set of independent paths. Each test case is forced to execute a certain test path of the control flow graph. Some cases might arise paths of the control flow graph have no test data to force execution. These paths are infeasible paths. Identification and removal of infeasible paths earlier will reduce testing efforts and cost. In the present work, we used Unified Modeling Language (UML) for detecting of these infeasible paths. For detection of these infeasible paths, the author builds the control flow graph from sequence diagram and then generated independent paths from it. Each path is converted into a set of a linear equation and solved. If there is an inconsistent solution, then the corresponding path is infeasible. The presented approach is evaluated on a case study of an automatic gold vending machine.

Business Process Outsourcing is a budding industry which currently employs millions of workers in the Philippines which draws applicants from undergraduate to professionals. It provides high-quality, well-paying jobs to millions of Filipinos while inspiring economic activity and investments all around. However, attrition rate of around 50 percent in the current year is a big challenge to predict employee turnover. This study came up with a model that can be adopted in the organization to predict possible attrition and guide the employers particularly the HR team in determining first-hand the type of applicant that they have by applying Data Mining techniques. The authors extracted significant predictors among the given data from a BPO company. Fast Correlation-Based Filtering Algorithm was performed to remove irrelevant data and increase learning accuracy. 1470 records with 21 attributes were initially provided and 17 were identified as significant after filtering and preprocessing of data was performed. The preprocessed data was used for model building with the application of Naïve Bayes Algorithm. The resulting model predicted percentage probability of hoppers and stayers. Among the 17 given variables, Total Working Years, Marital Status and Age ranked as the top predictors in determining possibility of attrition. The data was split into 60% training data or a total of 882 records and 40% testing data or a total of 588 records. The predicted number of stayers is 542 or 92.2% and the predicted hoppers or who likely to resign are 46 or 7.8% The model was tested and evaluated to check accuracy of result through confusion matrix cross validation technique which yielded an accuracy percentage of 84.69%.

Development of Knowledge Graph for University Courses Management
Статья научная
The task of Allocating courses to lecturers in many tertiary institutions is done manually by typing using word processor application. Motivated by the widespread application of knowledge graphs in different domains, we present automated approach based on knowledge graph to address the problem of manual course allocation to, a task usually carried out at the beginning of every semester or academic year by departments in tertiary institutions. The development of knowledge graph in a way that enables easy manipulation and automatic generation of course allocation schedule is the core contribution of this paper. Rather than storing the data in relational database tables, the system stores data in a knowledge graph which is in RDF/XML format and refer to it to support intelligent knowledge services. In addition to automatic generation of course allocation schedule, another important feature of the system proposed in this paper is its ability to enable easy implementation of tasks similar to Question Answering that are very important to education administrators, which the existing manual approach does not provide. Testing of the proposed system reveals its ability to perform effectively. Our approach of using Knowledge graph offers advantages such as flexibility and security.
