The Project Integration Architecture (PIA) implements a flexible, object-oriented, wrapping architecture which encapsulates all of the information associated with any application. The architecture allows the progress of a project to be tracked and documented in its entirety. Additionally, by bringing all of the information sources and sinks of a project into a single architectural space, the ab...

Sensor devices are used to collect the environment information. Wireless Sensor Network (WSN) is constructed with a set of data collection units. Base station, sinks and sensor devices are used in the WSN. Power resources, bandwidth and storages are the limitations of the sensor devices. Sink nodes are used to collect data from a group of sensor devices. Many to one traffic pattern based data c...

Since our daily life is strongly oriented towards the use of computer systems, everyone is affected by security incidents. Consequently, securing computer systems is of everyone’s interest. Many vulnerabilities in source code can be put down to insufficient validation of input data. Not long ago, a method was introduced to support the auditor in finding and fixing such vulnerabilities. In this ...

One issue with sensor networks is that there are bottleneck nodes, which relay more data than others. Generally, the bottleneck nodes are located near the sink in sensor networks. In order to balance them, systems introducing multiple sinks have been developed. However, there may not always be bottleneck nodes near the sink when sensor node distribution is not uniform. In such a situation, the ...

The overall circuitry of the cerebellar cortex has been known for over a century, but the function of many synaptic connections remains poorly characterized in vivo. We used a one-dimensional multielectrode probe to estimate the current source density (CSD) of Crus IIa in response to perioral tactile stimuli in anesthetized rats and to correlate current sinks and sources to changes in the spike...

Tropical forests play a major role in determining the current atmospheric concentration of CO2, as both sources of CO2 following deforestation and sinks of CO2 probably resulting from CO2 stimulation of forest photosynthesis. Recently, researchers have tried to quantify this role. The results suggest that both the carbon sources and sinks in tropical forests are significantly greater than previ...

A family of closed-form expressions for the scalar field of strongly focused Gaussian beams in oblate spheroidal coordinates is given. The solutions satisfy the wave equation and are free from singularities. The lowest-order solution in the far field closely matches the energy density produced by a sine-condition, high-aperture lens illuminated by a paraxial Gaussian beam. At the large waist li...

Extending our previous work on 2D growth for the Laplace equation we study here multidimensional growth for arbitrary elliptic equations, describing inhomogeneous and anisotropic pattern formations processes. We find that these nonlinear processes are governed by an infinite number of conservation laws. Moreover, in many cases all dynamics of the interface can be reduced to the linear time–depe...
