The Stability

Research highlights the importance of potato crop, which occupies a prominent food and economic status in food security besides rice, wheat and corn at the local and global level. Despite the expansion of the cultivation of potato crop in Iraq in general and Ameriyah district in particular However, potato productivity remains substandard, this may be due to a lack of knowledge of the most efficient varieties and not to use productive resources at the levels at which technical, specialized and economic efficiency is achieved. Therefore, the aim of the research is to determine the technical, specialized and economic efficiency according to the cultivated seed category. The data envelope analysis (DEA) method was used to estimate technical, specialized and economic efficiency, assuming constant and variable capacity returns. As a result of the study, the Safrana variety achieved the highest average technical efficiency according to the stability of the yield and capacity efficiency in addition to achieving the highest average specialized and economic efficiency, The Lapadia variety achieved the highest average technical efficiency, assuming that capacity returns have changed. Therefore, we recommend the adoption of items that achieve higher efficiency and the need to redistribute the elements of production better and Achieving the optimum levels at which technical, specialized and economic efficiency is achieved and saving what has been wasted.

The Relationship

Building upon previous research, this study examined the relationship between the deployment of spatial resources in the performance of spatial tasks and the level of spatial ability possessed by subjects. Ten Air Force Academy cadets, classified as either high or low in spatial ability by paper and pencil measures, performed tasks that presumably demanded spatial resources. Both the baseline and dual task level of performance was superior for the high spatial ability group. These findings are related to a variable capacity model of processing resources.

Efficient functioning of the wood market is crucial in a country where the forest sector is of strong macroeconomic importance. We investigate the possibility of noncompetitive behavior of the buyers in the Finnish pulpwood market. We simulate the buyers' behavior under alternative competition structures (perfect competition, Cournot oligopsony, and monopsony) and compare the simulated equilibria with the observed behavior in the years 1988–1997. In the static models the pulp industry firms are assumed to maximize their short-run variable profits either under fixed production capacity or, hypothetically, under variable capacity. The results suggest that, during the boom years, the industry has been capacity constrained, sometimes even for monopsony output. During the recession years, the actual wood prices have often been between simulated Cournot oligopsony and monopsony prices. Hence, noncompetitive behavior of the buyers is possible during the recessions. The capacity investment behavior of the industry is explored with dynamic models. The conclusions from these models depend on the price elasticity of pulpwood supply used.

Matching Performance

Variable-capacity matching of continuously variable-capacity double-impeller torque converter applied to a loader was studied in the article. Static variable-capacity matching of continuously variable-capacity double-impeller torque converter was performed under the two-impeller state and slipping state. Dynamic variable-capacity matching based on the V-shaped operating cycle was simulated in order to reflect the matching performance of the double-impeller torque converter more intuitively. The working speed of double-impeller torque converter together with engine was analyzed when the loader shoveled different materials, and the power performance and fuel economy of the whole machine were calculated. The continuously variable-capacity double-impeller torque converter applied to a loader could not only meet the requirements of matching different loader working conditions but also enhances the power performance and fuel economy of the whole machine in running condition compared with the original torque converter.

Heating Mode

The thermal performance of a new two-stage variable capacity air source heat pump (ASHP) and a horizontal ground loop ground source heat pump (GSHP) was investigated side-by-side at the Archetype Sustainable Twin Houses located in Toronto, Canada. The heat pumps were tested in cooling mode, as well as heating mode under extreme winter conditions. In cooling mode, the ASHP COP ranged from 4.7 to 5.7 at an outdoor temperature of 33 degrees C and 16 degrees C respectively, while the GSHP COP ranged from 4.9 (at an ELT of 8.5 degrees C and EST of 19.2 degrees C) to 5.6 (at an ELT of 12. 4 degrees C and EST of 17.8 degrees C). In heating mode, the ASHP COP ranged from 1.79 to 5.0 at an outdoor temperature of -19 degrees C and 9 degrees C respectively, while the GSHP COP ranged from 3.05 (at an ELT of 44.4 degrees C and an EST of 2.7 degrees C) to 3.44 (at an ELT of 41.5 degrees C and an EST of 5.48 degrees C) during the earlier winter test period. Data extrapolation and energy simulation was also performed to predict annual heat pump performance in Toronto as well as other Canadian regions.
