OBJECTIVES To establish the relative cost effectiveness of postnatal support in the community in addition to the usual care provided by community midwives. DESIGN Randomised controlled trial with six month follow up. SETTING Recruitment in a university teaching hospital and care provided in women's homes. PARTICIPANTS 623 postnatal women allocated at random to intervention (311) or contro...

OBJECTIVE To assess the effects of preventive home visits to elderly people living in the community. DESIGN Systematic review. SETTING 15 trials retrieved from Medline, Embase, and the Cochrane controlled trial register. MAIN OUTCOME MEASURES Physical function, psychosocial function, falls, admissions to institutions, and mortality. RESULTS Considerable differences in the methodological...

The aim of this paper is to investigate how practical store location decision-making balances formal modelling with the less well-studied informal qualitative inputs. By using case studies from one major UK food retailer, we find that informal knowledge has to be considered seriously alongside quantitative models despite the inclusion of such knowledge often proving challenging. In particular, ...

Train timetabling is a process of assigning suitable arrival and departure times to trains at the stations they visit and at key track junctions. It is desirable that the timetable focusses on passenger preferences and is operationally viable and profitable for the Train Operating Companies (TOCs). Many hard and soft constraints need to be considered relating to the track capacities, set of tra...

in recent years, need to increase the convenience of trips in railway vehicles causes that train operators and manufacturers focus on reducing the noise level which is sensed by passengers. in this paper, first the state of modeling acoustic noise in cab train is discussed and natural frequencies and acoustic mode shapes are derived and then formulation of acoustic pressure in the cab will be o...

background: national transport commission (ntc) classifies train driving as a high-level safety critical job. objective: to assess fitness-for-work among train drivers in yazd, central iran. methods: we evaluated 152 train drivers for their fitness for duty. the results were then compared with ntc guidelines. results: 63.8% of subjects were fit for duty, 34.2% fit subject to review, and 2.0% we...

Agricultural Extension services are among the most important rural services in developing countries. The services are considered to be a key driver of technological change and productivity growth in agriculture. In Kenya, like in the rest of the developing economies, agricultural extension has largely been delivered through supply–driven approaches. Due to perceived low impact of agricultural e...

In the United States, the freight railway industry is already running without much excess capacity. Hence, better planning and scheduling tools are needed to effectively manage the scarce resources, to cope with the rapidly increasing demand for railway transportation. The integration of freight train and passenger train scheduling and dispatching is an important railroad management task since ...

An observer based scheme is proposed to detect sensor faults in wind turbines. In the example used for the proposed scheme the wind turbine drive train is considered. A model of the drive train is used to design the observer, and in this model the wind speed is an important input, however, if an unknown input observer the fault detection scheme can be non dependent on the actual wind speed. The...
