Software testing is one of the main activities of software development life cycle (SDLC). More than 50% of the total cost of the project is consumed in software testing phase of SDLC (Beizer, 1990). The main aim of software testing is to produce better quality and reliable software. Broadly, software testing is of two types, white box testing and black box testing. Among the two test approaches towards software testing, white box testing is the preferred one owing to its ability to rec...

Interdisciplinary approaches are becoming increasingly popular in the health sector, specially to improve the diagnosis and management of various diseases [1–4]. Variety of methods of image processing and analyses are available for extracting valuable information from raw images taken from cameras [5]. With the advent of mobile phones, the concept of mobile health or mHealth emerged and it could be broadly described as a medical and public health practice supported by mobile devices su...

1 Introduction The problem of Point-of-Interest (POI) suggestion has gained lot of research attention recently due to the spread of Location Based Social Networks (LBSN). The problem is concerned with recommending interesting places for the users to visit. POI suggestion algorithms personalize the recommendations according to the current user’s context as well as the recorded user’s history. 2 E. Ali et al. In this research, we solve the POI suggestion problem in the context of Facet...

The Learning for Living Project (LFL) was designed and operated over a five year period between 2000 and 2004 by the READ Educational Trust in all nine provinces. In total, 957 primary schools participated in the LFL with 13 164 teachers and an estimated 875 000 learners. The project received R153 million in funding from the Business Trust (BT) and was implemented with the support and cooperation of the National and Provincial Departments of Education (DoE). The fundamental motivat...

What is the meaning we ascribe to the expression ‘reflexive governance’, thereby defining the conditions a collective action must fulfil in order to ensure, to the extent possible, that satisfaction of its members’ normative expectations is ‘maximised’; that is, in order to ensure what is generally called ‘governance in the public interest’? The expression ‘reflexive governance’ can only be understood if we first recall the project that has underpinned REFGOV.1 This...

Students wishing to study at a university where the medium of instruction is different from their mother tongue are often required to prove their proficiency by taking a language test for academic purposes. These tests are considered high-stakes because results are used to make decisions that have important consequences in students’ lives (Bachman & Palmer, 2010; Kane, 2013). In order to guarantee that scores are fair, language tests must be carefully scrutinized and validated to ensure tha...

Machine Learning field, methods based on Deep Learning (e.g. CNN, RNN) becomes the state-of-the-art in several problems of the multimedia domain, especially in audio-visual tasks. Typically, the training of Deep Learning Methods is done in a supervised manner, and it is trained on datasets containing thousands/millions of media examples and several related concepts/classes. During training, the Deep Learning Methods learn a hierarchy of filters that are applied to input data to classify/r...

Action learning has been underpinning an increasing amount of training practice throughout the world for nearly seven decades, since its genesis in the work of Reg Revans (ZuberSkerritt, 2002). Furthermore, action learning has been related to variety of disciplines. These application’s environments have ranged from private companies (Marquardt, 2004) to public sector organizations (Blackler and Kennedy, 2004) and in lesser extent to entrepreneurship development programs, such as start...

The Traveling Salesman Problem (TSP) is a classic optimization problem, which is formally defined by means of a weighted graph G = (V,E), in which V = {v1, v2, ..., vn} is a set of vertices and E = {vi , vj : vi ,vj ∈ V } is a set of edges. Each vertex vi ∈ V represents a city and each edge vi , vj  ∈ E connects the vertices vi and vj . The cost of travel from vi to vj is given by the weight value of the edge vi , vj . The best solution for a TSP instance involves finding th...

Correcting ab initio-based potential energy surfaces (PESs) has been a long-standing goal of computational chemistry. Several approaches dating from 30 years ago have been suggested. In one, a correction potential is added to an existing PES, and parameters of the correction potential are optimized by matching ro-vibrational energies to the experiment.1–3 This approach relies on being able to calculate exact rovibrational energies to make the comparison with the experiment robust. Thus,...
