Run-time services like accurate garbage collection and exception handling require static information about programs that is available only at compile-time. Compilers that use off-the-shelf code generators cannot easily produce such information and this severely limits the implementation choices for the run-time system. C-is a portable compiler-target language that includes support for high-leve...

The purpose of this work is that of presenting a version of the Reactive Tabu Search method (RTS) that is suitable for constrained problems, and that of testing RTS on a series of constrained and unconstrained Combinatorial Optimization tasks. The benchmark suite consists of many instances of the N-K model and of the Multiknapsack problem with various sizes and diiculties, deened with portable ...

One of the most important parameters of the system where wind turbine generators (WTGs) are connected is voltage profile at the point of common coupling (PCC). In the earlier stage, WTGs were possible to be disconnected from the system to avoid the damage of WTGs. Following the rapid injection of WTGs to the existing network during last decades, the transmission line operators (TSOs) require WT...

This paper presents a WEB-based manager tool for layout generation. Layout generators for MEMS, digital and analog circuits are provided. This manager allows the user to choose a particular device and set respective specific parameters for the automatic layout construction. Besides the top view layout illustration, such tool offers visualization features such as two-dimensional (2D) cross-secti...

The high penetration of micro-grid (MG) based on renewable distributed generators (DG) in the electrical network has brought about new issues on the stability and the transient operation of the grid. However, the disconnection and the reconnection of these local networks may give rise to undesired transient overcurrents and other damage that have to be avoided. In order to solve this problem, t...

In this paper, the concept of secondary control is applied for voltage unbalance compensation in an islanded microgrid. The aim of the proposed control approach is to enhance the voltage quality at the point of common coupling (PCC). Unbalance compensation is achieved by proper control of distributed generators (DGs). The DGs control structure mainly consists of active and reactive power contro...

Nowadays, chaos generators are an attractive field for research and the challenge is their realization for the development of engineering applications. From more than three decades ago, chaotic oscillators have been designed using discrete electronic devices, very few with integrated circuit technology, and in this work we propose the use of field-programmable gate arrays (FPGAs) for fast proto...

An important utility that digital computer systems should provide is the ability to generate random numbers. Certainly this is true in scientific computing where many years of experience has demonstrated the importance of access to a good random number generator. And in a wider sense, largely due to the encyclopedic efforts of Donald Knuth [18], there is now a realization that random number gen...

Although emissions of air pollutants from some military tactical equipment are not subject to the emissions standards, local communities near military bases must conform to the National Ambient Air Quality Standards. Military diesel generators are widely used in training. A portable in-plume system was used to measure fuel-based emission factors (EFs) for particulate matter (PM), carbon monoxid...
