This paper studies the distributed linearly separable computation problem, which is a generalization of many existing computing problems such as gradient coding and linear transform. A master asks ${\mathsf {N}}$ workers to compute fu...

Task assignment, the core problem of Spatial Crowdsourcing (SC), is often modeled as an optimization with multiple constraints, and quality efficiency its solution determines how well SC system works. Fairness a critical aspect task assignment that affects worker participation satisfaction. Although existing studies on have noticed fairness problem, they mainly focus at individual level rather ...

background: as a zoonotic pathogen, encephalitozoon cuniculi is a cause of serious disease in animals and people. the present study was to evaluate the health status examination of this seropositive animal care worker in our pre-vious study. methods: blood samples were taken from five workers. cia test was ap-plied to detect antibodies against e. cuniculi in blood serum. the indirect immunofluo...

Assignment model is a powerful operations research techniques that can be used to solve assignment or allocation problem. This study applies the assignment model to the course allocation problem in Nigeria tertiary institution in order to maximize lecturers’ effectiveness. A well-structured questionnaire was used to obtain data from lecturers and solved with Hungarian method. The study revealed...

Cell formation (CF) problem is one of the most important decision problems in designing a cellular manufacturing system includes grouping machines into machine cells and parts into part families. Several factors should be considered in a cell formation problem. In this work, robust optimization of a mathematical model of a dynamic cell formation problem integrating CF, production planning and w...

We investigate the design of electronic dispersion compensation (EDC) using full optical-field reconstruction in 10Gbit/s on-off keyed transmission systems limited by optical signal-to-noise ratio (OSNR). By effectively suppressing the impairment due to low-frequency component amplification in phase reconstruction, properly designing the transmission system configuration to combat fiber nonline...

[Purpose] This study was conducted to examine physical status and life satisfaction of workers in Korea. [Subjects] In total, 25,455 workers from eight geographical areas were evaluated from 2007 to 2008. [Methods] Physical status of the subjects was measured based on cardiopulmonary endurance, muscular strength, muscular endurance, flexibility, and explosive muscular strength, and a life satis...

We model long-run firm performance, management compensation, and corporate governance in a dynamic, nonstationary world. We show that managerial compensation and governance policies, which, in a single-period context, can best be rationalized by self-serving managerial influence over board policy, are shareholder-wealth maximizing in a dynamic setting. For example, shareholder wealth is maximiz...
