Pedestrian crossings in the UK and US require people to walk at 1.2 m/s to cross the road in time; however a large proportion of older people do not walk this fast, potentially discouraging walking or putting older people at risk of injury. We use longitudinal data to investigate changes in walking speed, and ability to cross the road in time, at older ages. 31,015 walking speed measurements we...

WCDMA release 5 supports peak bitrates for data services in the order of 10 Mbit/s, together with reduced delays and increased system throughput. In this paper, a brief introduction to release 5 is given and radio resource management principles associated with the high speed packet data bearers are discussed. Scheduling performance for WWW services, provision of bearers for streaming services, ...

Fuzzy logic controls and neuro-fuzzy controls are accustomed to increase the performance of air conditioning system. In this paper, we are trying to provide the new design air conditioning system by exploitation two logics, namely fuzzy logic and neuro-fuzzy management. This paper proposes a set of rule and uses 2 inputs specifically temperature and humidness and 4 outputs specifically compress...

Nowadays, Military products of superpowers countries have a high level of diversity, delivery speed, and appropriative operational functionality. Therefore, Production of varied, high quality and high speed delivery military products, is essential for enhance Iran's defensive deterrence power. Defense industries supply chain agility is an answer to how to produce military products with these f...

W hile speed management is a key element in the road safety strategies of many regional and national governments, there is little consensus and much controversy over the specific speed reduction interventions that have been employed. Considerable heat—and relatively little light—has accompanied the public debates. This paper reviews the evidence for a population based speed reduction strategy, ...

Dynamically changing CPU voltage and frequency have been shown to greatly save the processor energy. These adjustments can be done at specific power management points (PMPs), which are not without overheads. In this work we study the effect of different overheads on both time and energy; these can be seen as the overhead of computing the new speed, and then the overhead of dynamically adjusting...

Nowadays, we have witnessed the widely recognized phenomenon of high speed data streams. Various statistics computation over data streams is often required by many applications, including processing of relational type queries, data mining and high speed network management. In this paper, we provide survey for three important kinds of aggregate computations over data streams: frequency moment, f...
