The Fourier transform usually has been used in the past for analysis of stationary and periodic signals. Its interest is the knowledge of spectral components existing in a waveform; it doesn't matter the moment where they happen. However, when the time localization of the spectral components is needed, the Wavelet Transform (WT) can be used to obtain the optimal timefrequency representation of ...

This paper presents present three novel buffer schemes for system on chip applications that have an interconnection network. The proposed schemes are based on a DAMQ self-compacting buffer to provide larger available buffer space per channel for incoming flits. The proposed schemes outperform existing approaches, and optimize buffer management by providing better throughput when the network has...

This paper presents a pair of algorithms for output and input of pointer structures in binary format. Both algorithms operate in linear space and time. They have been inspired by copying compacting garbage collection algorithms, and make similar assumptions about the representations of pointer structures. In real programs, the transfer of entire pointer structures is often inappropriate. The al...

A unidirectional heap is a heap where all pointers go in one direction, e.g. from newer to older objects. For a strict functional language , such as Erlang, the heap may be arranged so that it is unidirec-tional. We here present a compacting garbage collection algorithm which utilizes the fact that a heap is unidirectional. Only one memory space is used in our algorithm. In fact, no extra memor...

The framework of Finite-State Intersection Grammars employs a parsing technique according to which several finite-state automata are intersected to determine the output automaton. Implementation of the intersection parser has turned out to be a difficult task. Several problems in efficiency arise when disambiguation choices are based on long contexts with many don’t cares. We are concerned with...

Acrylic polymer that is highly stable against chemicals and is a good choice when concrete is subject to chemical attack. In this study, self-compacting concrete (SCC) made using acrylic polymer, nanosilica and microsilica has been investigated. The results of experimental testing showed that the addition of microsilica and acrylic polymer decreased the tensile, compressive and bending strength...

As a vibration- free concrete, self- compacting concrete (SCC) can be easily used in the absence of consolidation, therefore; it is a good option for repairing and retrofitting concrete structures. The quality of repair layer is highly effective on a successful repair. Accordingly, in this study, factors affecting the quality of fiber-reinforced self-compacting concrete repair layer, including ...
