This paper presents the methodology and the results on the design and development of an autonomous golf ball picking robot. The strategy followed to develop a commercial product is presented, based on prior identification requirements, which consists of picking up golf balls on a Driving Range in a safe and efficient way. A functional prototype was built and tested. It has autonomy of up to 8h ...

A constant-rate multi-mode system is a hybrid system that can switch freely among a finite set of modes, and whose dynamics is specified by a finite number of real-valued variables with mode-dependent constant rates. Alur, Wojtczak, and Trivedi have shown that reachability problems for constant-rate multi-mode systems for open and convex safety sets can be solved in polynomial time. In this pap...

The intensive development of gas transport and compressor manufacturing aimed at increasing the unit capacities pumping units, creating high-flow centrifugal compressors, productivity shops has led to appearance fundamentally new problems in diagnosis industrial pipelines. reasons for premature failure piping manifold stations can be associated with both high static voltage pipelines a level vi...

Introduction Over the last couple of years I have been advocating and exploring educational uses of Web 2.0 applications at a university in Hong Kong. This culminated in a concerted research effort under the umbrella project ‘Pioneering Web 2.0 in education’ which includes smaller projects exploring applications of Wikies, blogs, social networking and social book-marking. This paper briefly rep...

The Full Adders (FAs) constitute the essential elements of digital systems, in a sense that they affect the circuit parameters of such systems. With respect to the MOSFET restrictions, its replacement by new devices and technologies is inevitable. QCA is one of the accomplishments in nanotechnology nominated as the candidate for MOSFET replacement. In this article 4 new layouts are presente...

Introduction: Postgraduate medical education involves the use ofonline-learning tools. However, there is a paucity of data on theuse of online-learning among doctors who are in their 1st and 2ndyears of professional work after graduating from medical school(also known as Foundation doctors). Our aim was to explore theuse of online-learning among Foundation doctors.Methods: A cross-sectional stu...

Introduction: Online formative assessments (OFA’s) have beenincreasingly recognised in medical education as resources thatpromote self-directed learning. Formative assessments are usedto support the self-directed learning of students. Online formativeassessments have been identified to be less time consuming withautomated feedback. This pilot study aimed to determine whetherparticipation and pe...
