Teleradiology involving the transfer of vital patient information such as scan images is an important technology to facilitate effective and efficient provision of neurosurgical care in the setting of scarce resources and geographic isolation. We review the implementation of teleradiology initiatives in the small city state of Singapore and its potential and need in the large province of Ontari...

A service ecosystem is a virtual space ideally distributed across networks and geographical areas where vast numbers of services and other digital entities can coexist and converge to form ad-hoc solutions. In this paper we present experimental results showing the performance of two optimization models in service ecosystem. We describe the two models and how they operate under service ecosystem...

Geographical Information Systems (GIS) have long bridged the gap between geo-information databases and applications. Although conceptual modelling approaches for GIS have been particularly successful in the representation of the specific properties of geographical information, there is still a need for a better integration of user intentions and usage. This paper introduces a conceptual framewo...

In this paper, a novel adaptive sliding mode control for rigid robot manipulators is proposed. In the proposed system, since there may exist explicit unknown parameters and perturbations, a Lyapunov based approach is presented to increase system robustness, even in presence of arbitrarily large (but not infinite) discontinuous perturbations. To control and track the robot, a continuous controll...

The world is changed. I feel it in the water. earth. smell air. Much that once was lost.[1]BackgroundThe maritime domain has grown significantly past ten years. It currently a vast interconnected network of cargo

Is the use of an online course delivery format, when compared with the more traditional face-to-face format, good or bad in the context of university education? Those who subscribe to the no-significant-difference perspective argue that online delivery is good, because it allows students with time and geographic distance constraints to obtain the education that they need, with no significant ne...

Point of Departure " First Law of Geography " : " Everything is related to everything else, but near things are more related than distant things. " — Waldo Tobler, 1970 Fundamental Dialectological Postulate: " Geographically proximate varieties tend to be more similar than distant ones. " — Nerbonne & Kleiweg, 2007 Tested on different types of data (surveys, corpora) Several kinds of geograph...

This paper introduces an ontology-based approach to relate properties observed by sensors to geographical processes and events. We use the basic categories in DOLCE to classify them. We illustrate our approach with examples from the surface hydrology domain.

It is a useful premise to assume that every document in a collection and every query issued to an information retrieval (IR) system is geography-dependent. If one can determine what area an article is about (i.e., its’ geographical scope), this information can be used to improve the accuracy with which people, places and organizations named in the article can be located. More importantly, geogr...

Measuring how much cybercrime exists is typically done by first defining cybercrime and then quantifying how many cases fit that definition. The drawback is that definitions vary across countries and many cybercrimes are recorded as traditional crimes. An alternative is to keep traditional definitions of crime and quantify the amount of associated information and communication technologies (ICT...
