Aviation, military, police, and health care personnel have been particularly interested in the operational impact of sleep restriction and work schedules given the potential severe consequences of making fatigue-related errors. Most studies examining the impact of sleep loss or circadian manipulations have been conducted in controlled laboratory settings using small sample sizes. This study exa...

abstract Evaluating mobile applications and devices is particularly challenging given the variability of users, uses, and environments involved. This chapter introduces usability evaluation methods (UEMs) for mobile applications. Over the past decades various usability evaluation methods have been developed and implemented to improve and assure easy-to-use user interfaces and systems. Since mos...

In the software development process, testing is one of the most human intensive steps. Many researchers try to automate test case generation to reduce the manual labor of this step. Negative selection is a famous algorithm in the field of Artificial Immune System (AIS) and many different applications has been developed using its idea. In this paper we have designed a new algorithm based on nega...

The Ohaaki Geothermal field is situated in the Taupo Volcanic Zone of New Zealand. It was the second geothermal field in New Zealand to be developed and is used primarily for electricity generation. Wells were first drilled in the Ohaaki field during the early 1960’s. After a period of well testing following drilling, there was a long period of field recovery until steam production for electric...

Various problems of combinatorial optimization and permutation can be solved with neural network optimization. The problem of estimating the software reliability can be solved with the optimization of failed components to its minimum value. Various solutions of the problem of estimating the software reliability have been given. These solutions are exact and heuristic, but all the exact approach...

since the evolution of public administration as an academic and scientific discipline, different competitive approaches have come forward in this area. public administration as a profession, a scientific field and a political process; or, public administration as an area totally distinguished from business management; and legal, political and administrative approaches towards public administrat...

This work aimed to study the intrinsic tolerance of Greek lentil accessions to imazamoxherbicide by combining bioassays, pot and field experiments. Initially, 31 genotypes wereevaluated in Petri dish bioassays for their tolerance to six concentrations of imazamox. Theaverage root length of 10 lentil seedlings/dish at seven days after herbicide application was usedfor non-linear regression analy...
