There remain several unexplored questions in relation to the analysis of regional innovation systems (RISs). This is the case, for example, about the nature of some types of system failures that avoid developing innovations in regional economies. In this case, system failures may hinder the...

In this paper, a novel CAES system (compressed air energy storage) is proposed as a suitable technology for the energy storage in a small scale stand-alone renewable energy power plant (photovoltaic power plant) that is designed to satisfy the energy demand of a radio base station for mobile...

An Energy Bag is a cable-reinforced fabric vessel that is anchored to the sea (or lake) bed at significant depths to be used for underwater compressed air energy storage. In 2011 and 2012, three prototype sub-scale Energy Bags have been tested underwater in the first such tests of their kind. In...

This paper introduces the new ATISBAT model for generating accelerated-time simulations of baggage handling in an airport terminal. The philosophy of this model combines ideas from cellular automaton and neural network theories. The basics of this model was presented at ACA’2012 (in the...

In this paper we introduce a new model, called the GRAM model, that provides an accelerated-time simulation of traffic on a motorway. The model provides an accelerated-time simulation using ideas and techniques from both cellular automata and neural network models. It has been implemented in a...

This paper introduces a new low-cost hybrid drivetrain concept based on compressed air energy storage. In contrast to most contemporary approaches to pneumatic hybridization, which require modification to the primary power plant, this concept is based on a stand-alone pneumatic system that could...

Economic theory posits that the removal of impediments to trade should redound to improvement in the overall well-being of all nations. Unfortunately, for many developing countries, this has not been the case; upon significantly reducing their tariffs, they are yet to see any tangible benefits....

Some concerns relating to the demographics of the region as they impact on agricultural production were discussed. Traditional agriculture was in many instances on the decline. Competitive elements have been seizing the opportunity to supply the region through import substitution. Small and...

Alcohol consumption is considered an important social activity but a major health risk in Latin American and Caribbean countries (LAC). Alcohol consumption net benefits are doubtful and the factors influencing alcohol consumption in the LAC countries are not well documented. In this study, we...

Several Caribbean sugar producing countries are actively looking for viable alternatives to recover some of the expected lost revenues due to the WTO (World Trade Organization) ruling that sugar subsidies in the European Union (EU) are illegal. One alternative worth considering is exporting...

The concept of food insecurity at the household and individual levels has been an area of extensive research in the late 1980s by individual researchers and public agencies. This work culminated in the development of the US Food Security Survey Module (FSSM), which is now seem to be the standard...
