Server farms are popular architectures for computing infrastructures such as supercomputing centers, data centers and web server farms. As server farms become larger and their workloads more complex, designing efficient policies for managing the resources in server farms via trial-and-error becomes intractable. It is hard to predict the exact effect of various parameters on performance. Stochas...

Restoration and maintenance of habitat diversity have been suggested as conservation priorities in farmed landscapes, but how this should be achieved and at what scale are unclear. This study makes a novel comparison of the effectiveness of three wildlife-friendly farming schemes for supporting local habitat diversity and species richness on 12 farms in England.The schemes were: (i) Conservatio...

Ethiopia has the largest livestock population in Africa but the contribution of this resource to the economy is limited and yet the country is in poverty. Dairy development has a big role for the contribution of income generation and employment. Demand for dairy products seems to exceed supply in the country in general and the study area in particular. Hence, the situation of dairy production a...

This paper presents the results of an analysis that predicts the scale efficiency of individual farms and analyses the differences in scale efficiency over time and between farms. Representative farm account data for 1985–2006 are used, and the study applies stochastic frontier analysis using an input distance–function approach. The results show that pig farms have improved their input scale ef...

Abstract Automated additive printer farms, which operate several printers in parallel and thus increase the productivity, are an efficient way to realize a fully flexible mass production, as has been shown by number of examples. By means specifically developed calculation method virtual representations various farm concepts simulation environment, analyzed regarding cost structure productivity....

respiratory disorders are major concern for dairy cattle industry. viruses and bacteria in combinationwith stress play a key role in triggering acute respiratory infections. the most important viral agents arebovine viral diarrhoea virus (bvdv), bovine herpes virus type 1 (bhv-1), bovine respiratory syncytial virus(brsv), parainfluenza virus type 3 (piv-3) and bovine adenovirus (bav). this cros...

The laudable intentions of science to research the effects of different variables on the ability to predict the time death interval accurately have become embroiled onmultiple complex fronts. The colloquial and persistent use of the term ‘body farm’, the rhetoric that surrounds media reporting, and the sometimes distasteful display of the subjects, detract significantly from any scientific meri...

Introduction Throughout the world, the business of dairy farming is rapidly evolving. Consumption of dairy products remains strong but fewer farms are producing more milk using less labor and more purchased services. In the United States, the number of dairy farms dropped from 192,700 in 1990 to 92,000 in 2002 (Wisconsin Agricultural Statistics, 2003). The productivity of these larger farms has...
