Considerable research has been performed in applying run-time reconfigurable component models to the domain of wireless sensor networks. The ability to dynamically deploy and reconfigure software components has clear advantages in sensor networks, which are typically large in scale and expected to operate for long periods in the face of node mobility, dynamic environmental conditions, and chang...

Context. Distributed software development is currently a modern practice in software industry. This is especially true in Open Source Software (OSS) development community. Understanding how developers’ practices are on those projects may guide communities to successfully manage their projects. Goal. We mined two repositories of the Apache Httpd project in order to gather information about its d...

Microcontroller software typically consists of a few hundred lines of code only, but it is rather different from standard application code. The software is highly hardware and platform specific, and bugs are often a consequence of neglecting subtle specifications of the microcontroller architecture. Currently, there are hardly any tools for analyzing such software automatically. In this paper, ...

A central question in the law and economics literature is whether, with limited resources, police should be deployed randomly over many locations or establish a predictable presence in crime “hot spots”. Critics of static hot spot enforcement have argued that this approach will only lead to crime shifting to other locations. But for short “crackdowns”, this may not apply, as it make take some t...

The effective deployment of police resources is heavily dependent on the quality of analysis available. Over the past decade, the term "hot spots" has come to be commonplace in policing, and it is rare to find a police agency that cannot or does not identify spatial clustering of criminal incidents. Equally rare is the consideration of any other type of clustering. The following study highlight...

The electricity market is a very peculiar market due to the large variety of phenomena that can affect the spot price. However, this market still shows many typical features of other speculative (commodity) markets like, for instance, data clustering and mean reversion. We apply the diffusion entropy analysis (DEA) to the Nordic spot electricity market (Nord Pool). We study the waiting time sta...

background: extremely low frequency electromagnetic fields (elf-emf) have been common in daily life all over the world. they have produced by power lines and electrical appliances, but higher levels of them have raised a lot of concerns about their carcinogenesis. both epidemiological and laboratory studies have suggested that emfs might increase cancer incidence, including acute childhood leuk...

For many years, two-dimensional gel electrophoresis has been the method of choice for the investigation of complex mixtures of proteins. Although there are a number of emerging technologies that can be applied to proteomics, none can yet yield routinely the breadth of information available from two-dimensional gels. To be able to obtain instant information regarding molecular mass and pI, as we...

In order to investigate the safety and stability of loess high slope under dynamic ramming, MatDem software was used simulate process heavy rammer compacting spot which 11 m away from toe slope. The applied with different energies 10000 kN·m, 8000 6000 kN·m. this way, action tamping can be determined. results show that presented circular landslide damage by compaction. Under same ramming times,...

The proper deployment of sensors is very important for the successful completion of the sensing tasks due to the inevitable relation with the physical world. This paper presents a novel method for the redeployment of mobile nodes in a hybrid sensor network consisting of a collection of both static nodes and mobile nodes. In such a sensor network, the locomotion ability of mobile nodes helps the...
