This paper describes the design of a portable, cheap and easy to handle microcontroller-based heart monitoring system using a Atmega32 model-based microcontroller and GLCD. The project is capable of detecting and distinguishing the normal heart signal from an abnormal one. A circuit was designed to convert the sound signals from the heart into electrical signals. The signal so obtained was then...

Researchers disagree about the critical drivers of success in high-tech markets and whether high-tech markets are efficient. Many authors suspect that network effects play a big role leading to perverse markets in which the dominant brands do not have the best quality. At the same time, few researchers assert that high-tech markets are efficient with best quality brands dominating. We develop a...

results of an evaluation of the impact of agricultural science and technology (as and t) policy system institutions on efficiency and technical change in kenyan and ugandan agriculture are presented here. data envelopment analysis was used to derive efficiency and technical change and logistic regression applied to delineate as and t institutions that induced efficiency and technical progress. ...

Business managers are facing the dynamic environment nowadays, and encountering more and more difficulties in decision-making. In order to formulate suitable strategies, they must consider all aspects of dynamic environments and situations which they meet. Sun Tzu's The Art of War is probably the oldest military book in Chinese and the principles which Sun Tzu advocated are still valuable in ma...

Sustainable development has been widely considered as an important issue in the hightech industry. The purpose of this study is to investigate the factors motivating sustainability development strategies adoption and implementation and to study the relationships between the motivating factors and the readiness of implementation at strategic level (management willingness) and tactical level (res...

Current approaches to CSCW application support are limited by their failure to support application distribution, internal application concurrency, anonymous communication, easy application integration, and run-time application behaviour modi cation. This paper argues that these limitations may be addressed at the language level. Accordingly, we introduce a new model and language which assimilat...

Creativity has become an important factor in recent years, as companies need to be able to quickly adapt to take advantage of new opportunities and handle fast paced changes in their environment. Creativity theorists have proposed models to explain creative thought that go beyond the individual to encompass social aspects of creativity. However, most existing research concerns an individual and...

This paper presents an analysis of the modifications that a synchronous computer support for collaborative writing introduces into the organization of the co-authors’ writing. The analysis is grounded in case studies of different groups of co-authors writing a report together face-toface and at a distance through a collaborative writing computer system. Drawing from these studies I suggest that...

This paper presents an analysis of Liberia’s membership to date in the Africa Coast to Europe (ACE) submarine cable consortium and its initial governance structures, challenges and successes. A connection to the ACE cable will offer Liberia its first terrestrial international Internet gateway and is seen as a path to increasing ICT access and use in that country. This study employs a four-point...

This paper discusses two examples of how shared technical support platforms are adapted and developed in organizations. One is support for object oriented design and programming, the other, production of documents in an office. These two cases represent longitudinal studies of the use, the adaptation and the development of these platforms. This development involved active mediation of platform ...
