Reprogramming is an important issue in wireless sensor networks. It enables users to extend or correct functionality of a sensor network after deployment, at a low cost. In this paper, we investigate two problems: improving the energy efficiency and improving the delay of reprogramming. As enabling technologies we use data compression and incremental updates. We analyze different algorithms for...

The fixed combination eye drop Duotrav is a combination of travoprost 0.004% and timolol maleate 0.5%. Both travoprost and timolol have been used separately for the treatment of glaucoma by lowering intraocular pressure. Multiple studies have demonstrated the efficacy and safety of the fixed combination travoprost/timolol for the treatment of open-angle glaucoma and ocular hypertension. The onc...

comparative advantage of corn in comparison with other competing crops was investigated applying linear programming, to 2004-2005 data related to classic index (drc) in khuzestan. results showed that corn benefits from a comparative advantage in all cities of khuzestan province with acreage having been increased in the cultivation pattern of 37.5 % of the cities. in addition, comparing optimal ...

An increasing number of studies in a wide range of natural systems have investigated how pulses of resource availability influence ecological processes at individual, population, and community levels. Taken together, these studies suggest that some common processes may underlie pulsed resource dynamics in a wide diversity of systems. Developing a common framework of terms and concepts for the s...

In this thesis we combine Turing categories with Cartesian left additive restriction categories and again with differential restriction categories. The result of the first combination is a new structure which models nondeterministic computation. The result of the second combination is a structure which models the notion of linear resource consumption. We also study the structural background req...

High Performance Computing (HPC) clouds need to be efficiently shared between selfish tenants having applications with different resource requirements and Service Level Objectives (SLOs). The main difficulty relies on providing concurrent resource access to such tenants while maximizing the resource utilization. To overcome this challenge, we propose Merkat, a market-based SLO-driven cloud plat...

Agent oriented software engineering (AOSE) is an emerging field in computer science  and  proposes some systematic ideas for multi agent systems analysis, implementation and maintenance. Despite the various methodologies introduced in the agent-oriented software engineering, the main challenges are defects in different aspects of methodologies. According to the defects resulted from weaknesses ...

importance of human resources and its unique role as a strategic resource, designer and systems executive and organizational systems has found higher position than in the past as far as the advanced enterprise thinking considers human being as the most important resource and asset for an organization. today, new approaches to human resource management emphasizes that should human resource with ...
