Transaction processing applications such as those exemplified by the TPC-C benchmark are among the most demanding I/O applications for conventional storage systems. Two complementary techniques exist to improve the performance of these systems. Eager-writing allows the free block that is closest to a disk head to be selected for servicing a write request, and mirroring allows the closest replic...

In the absense of frictionless trade, domestic productivity will be a major determinant of prices. Using repeated cross-sections of absolute prices of individual goods across European countries, I find that products of an industry tend to be cheaper in countries with higher productivity in that industry. Similarly, countries with higher productivity in manufacturing have lower prices for produc...

Abstract This study was conducted to evaluate the effect of floor space allowance on productivity sows. A total 48 sows (Landrace × Yorkshire; 220.64 ± 5.18 kg average initial body weight) were randomly assigned four treatments (floor 1.9 m2, 2.1 2.3 2.5 m2). Diets titrated or exceeded nutrient requirements for recommended by Nutrient Requirements Swine National Research Council. All moved allo...

Analysis of the factors affecting the productivity of enterprise software projects the data of which had many missing values revealed five important findings. (1) Productivity was proportional to the root of the fifth power of test case density and the root of the fifth power of fault density. (2) Developing software with a high level of security or reliability are the main causes of low produc...

Low food availability is a major structuring force in deep-sea benthic communities, sustaining only very low densities of organisms in parts of the abyss. These low population densities may result in an Allee effect, whereby local reproductive success is inhibited, and populations are maintained by larval dispersal from bathyal slopes. This slope-abyss source-sink (SASS) hypothesis suggests tha...
