Realistic mathematical models are of great importance for studying the optical performance of the human eye. Light propagation algorithms provide robust methods to calculate field distributions inside a homogeneous medium, and thus they can be applied to the study of…

What is the relationship between the awareness of linguistic prestige and the security or insecurity in the use of minoritised languages? Is formal linguistic insecurity (as initially described by Labov) the same as the speakers’ perception of linguistic insecurity? Which…

The ntcA gene from Synechococcus sp. strain PCC 7942 encodes a regulatory protein which is required for the expression of all of the genes known to be subject to repression by ammonium in that cyanobacterium. Homologs to ntcA have now…

Over the last three decades, several studies have applied Hellison’s Teaching Personal and Social Responsibility (TPSR) model; most of them have generated strong empirical evidences that support that theoretical framework. TPSR is a programme for positive youth development through physical…

We study stability properties of a proximal point algorithm for solving the inclusion 0 ∈ T (x) when T
is a set-valued mapping that is not necessarily monotone. More precisely we show that the convergence of
our algorithm is uniform,…

The localization of a mobile robot in a real environment is a complex task. In this paper, an algorithm that solves the global localization is presented. The proposal is based on a merit function that ranks different possible poses obtained…

If robotic companions are to be used in the near future by aging adults, they have to be accepted by them. In the process of developing a methodology to measure, predict and explain acceptance of robotic companions, we researched the…

A Discrete Event System (DES) is a discrete state space dynamic system that evolves in accordance with the instantaneous occurrence, at possibly unkown times, of physical events. Given a DES, its behavior (the sequence of displayed events) may not satisfy…

While most scholars and researchers recognize that entrepreneurship occurs differently in other countries, there are relatively few undergraduate courses that focus on International Entrepreneurship. Further, of those with an International focus, few provide students with an opportunity to interact with…

The kinetics of the global thermal decomposition of a PET fibre cloth have been studied in three different atmospheres with nitrogen, 20 and 10% oxygen, using thermogravimetric analysis (TGA) between room temperature and 1050 K. Three different heating rates were…
