The paper describes an approach to extend the coverage of a Link grammar based parser on the constructions that are not being handled currently by the grammar. There are about thirty types of constructions which we have identified till now. In order to make Link grammar handle these constructions, we introduce a preprocessor and a postprocessor. The idea is to handle such constructions via some analysis...
Static random access memories (SRAMs) comprise an increasingly large portion of modern very large scale integrated (VLSI) circuits. The increasing importance of embedded SRAM is due to its low circuit activity factor, leading to low active power density, and productivity of design. The power consumption has become an important issue and has lead to the development of numerous schemes aimed at limiting...
In this paper, a new technique is proposed for multiplication of two sampled analog signals and the output is in digital form. One analog signal is fed to the input of Delta sigma modulator (DSM1) after sampling. The sampled output of the second analog signal is negated or not negated depending on the bit state at the output of DSM1 and is fed to the input of second DSM (DSM2). The resulting bit stream...
Binary decision diagrams (BDDs) are the most frequently used data structure for handling Boolean functions because of their excellent efficiency in terms of time and space. Algebraic decision diagrams (ADDs) have been used to solve general purpose problems such as matrix multiplication, logic synthesis and formal verification. We propose a new type of BDD called weights binary decision diagram (WBDD)...
The number of tasks executing in MPSoC platform can exceed the available resources, requiring efficient run-time mapping strategies to meet the real-time constraints of the applications. This paper describes two new run-time mapping heuristics for mapping applications onto NoC-based heterogeneous multiprocessor systems-on-chip (MPSoC). The heuristics proposed in this paper attempt to map the tasks...
Graphs are being increasingly used to model a wide range of scientific data. Such widespread usage of graphs has generated considerable interest in mining patterns from graph databases. While an array of techniques exists to mine frequent patterns, we still lack a scalable approach to mine statistically significant patterns, specifically patterns with low p-values, that occur at low frequencies. We...
In this paper, we have shown that recognition of machine printed characters can be modeled around the geometry of an alphabet. This geometry is used as a basis for recognizing various characters. The present technique can be implemented for any language, provided, the alphabets of the respective language are made up of geometrical shapes, which is typically true.
Recently a new formulation for realizing a floating inductance (FI) using an OMA (operational mirrored amplifier), which takes into account the dominant pole of the op-amp employed in the OMA, without requiring any external capacitor was proposed. The proposition, however, suffered from a limited input-dynamic-range of operation owing to limited open-loop signal handling capability of the op-amp used...
In this paper, we have presented a talk-through application describing the basic significance of a software defined radio (SDR). We have shown the procedure to build in hardware a specific receiver to work with this application.
In this paper we report the mechanism of charge transport in conducting polymers. The basic concept of defect states in conjugated polymers (solitons, polarons and bipolarons in conjugated polymers) are briefly discussed. This paper addresses sources of disorder in conducting polymers depend on inhomogeneous doping and also the synthesis routes. We synthesized the conjugated polymers by different...
Graphs have become popular for modeling scientific data in recent years. As a result, techniques for mining graphs are extremely important for understanding inherent data and domain characteristics. One such exploratory mining paradigm is the k-MST (minimum spanning tree over k vertices) problem that can be used to discover significant local substructures. In this paper, we present an efficient approximation...
We propose a technique for evaluating the statistical significance of frequent subgraphs in a database. A graph is represented by a feature vector that is a histogram over a set of basis elements. The set of basis elements is chosen based on domain knowledge and consists generally of vertices, edges, or small graphs. A given subgraph is transformed to a feature vector and the significance of the subgraph...
