This paper describes a flexible, cost-effective, wireless in-home activity monitoring system for assisting patients with cognitive impairments due to traumatic brain injury (TBI). The system locates the subject with fixed home sensors and classifies early morning bathroom activities of daily living with a wearable wireless accelerometer. The system extracts timeand frequencydomain features from...

This paper introduces a system that uses brainwaves, or EEG (electroencephalogram), information to compose and play music in real-time. The system composes music using generative grammars and transition rules controlled by means of information extracted from the EEG of the subject. The paper starts by noting the various attempts at the design of systems that make music from the EEG signals, fol...

The evidence on limited computational ability implies that investors will have difficulty making optimal choices when information requires complex processing, such as aggregating risks across investments or time. The implication for investment advisors is that information should be processed and presented in a format that simplifies optimal choices. For example, individual investments could be ...

Braille code, employing six embossed dots evenly arranged in rectangular letter spaces or cells, constitutes the dominant touch reading or typing system for the blind. Limited to 63 possible dot combinations per cell, there are a number of application examples, such as mathematics and sciences, and assistive technologies, such as braille displays, in which the 6-dot cell braille is extended to ...

Abstract Technology assessment and selection problems have gained importance in recent decades as the used technology often determines enterprises’ competitive advantage. Due to extensive catalogue of criteria that should be considered and, on other hand, available technologies solutions, decision-making process choosing a becomes significant challenge for organisations individuals. This study ...

In this paper, we consider task assignment problem in a cluster of servers. We show that optimal static task assignment is tantamount to equalizing an appropriate cost functions associated with the servers. We also propose an improvement of dynamic Shortest Expected Delay (SED) task assignment policy.

Introduction: Decentralized wastewater treatment facilities are an expensive approach for developing countries. Decentralized wastewater treatment plants (DWWTPs) are a flexible technology. They have low construction and operational costs. Site selection is the most significant stage in the implementation of a DWWTPS. Therefore, the present study aimed to perform a site selection among the prop...

The aim of this research is to design, develop, evaluate and manufacture an assistive/adaptive computer peripheral to facilitate interaction and navigation within Virtual Learning Environments and related learning content for people with physical learning and disabilities. The function of the device will be software specific; however the most common primary functions are those of selection, nav...

This paper develops an idea flows theory of trade and growth with heterogeneous firms. New firms learn from incumbent firms, but the diffusion technology ensures entrants learn not only from frontier technologies, but from the entire technology distribution. By shifting the productivity distribution upwards, selection on productivity causes technology diffusion and this complementarity generate...
