This paper investigates the researches was done on the TI-ADC considering various problems specially the mismatches occur in during conversion. As we studied, the main reason of these mismatches is the non-uniform manufacturing of the TI-ADC ICs, and due to these reasons mismatches in the form of time, frequency, offset and gain introduced in the signals during conversion process. Many research...

With the rapid development of information and communication technology, modern business activities become increasingly dependent on Information Resource Management (IRM). To manage implemented information resources successfully in practice, one great challenge facing the management team is how to deal with various mismatches between information provider and information user. In this paper, the ...

We are going to present a classification of verb centered mismatches between Spanish and English. This classification is based on a proposal for lexical representation of linguistic knowledge and therefore falls within the scope of lexical semantics. Our proposal is based on a model for lexical description that takes into account meaning components, event structure and diathesis alternations. I...

In this paper, we address the question, ’~/hat types of MT divergences and mismatches must be accommodated in the lexicon?" In our work, we have focused on the treatment of divergences and mismatches in an interlingual (as opposed to a tranfer-based) MT system. In such systems, one uses monolingual lexicons for each of the language under consideration, so divergences and mismatches are not hand...

Gain and timing mismatches in a time-interleaved analog-todigital converter (TI-ADC) cause spurious images in its output spectrum thus effecting its performance. In this paper. we present an efficient digital blind identification structure to adaptively estimate gain and timing mismatches by using the filtered-error least-mean square (FxLMS) algorithm. The identification of mismatches helps in ...

Abstract. Composition of heterogeneous software components is required in many domains to build complex systems. However, such compositions raise mismatches between components. Software adaptation aims at generating adaptors to correct mismatches between components to be composed. In this paper, we propose a formal approach based on Petri nets which relies on mapping rules to generate automatic...

In this paper we consider several variants of the pattern matching problem. In particular, we investigate the following problems: 1) Pattern matching with k mismatches; 2) Approximate counting of mismatches; and 3) Pattern matching with mismatches. The distance metric used is the Hamming distance. We present some novel algorithms and techniques for solving these problems. Both deterministic and...

Although the membrane process is recognized as a green technology and is considered as a key player in the process intensification movement, it is not widely known that the fabrication of membrane itself generates significant amount of waste. With the growing membrane market, more efforts must be placed on improving the sustainability of membrane fabrication such as replacing toxic organic solv...

multileaf collimator (mlc) is among the radiation field shaping systems used for conformal radiotherapy and intensity modulation radiation therapy techniques. the mlc system that has been designed and fabricated in this study includes 52 leaves, 52 stepper motors, 2 dc motors, 16 programmable logic controllers (plcs) and one human machine interface (hmi). this system can be mounted on conventio...

In this paper we propose a digital background adaptive calibration technique for correcting offset and gain mismatches in multi-path sigma-delta (ZA) modulators. The proposed technique allows us to cancel the spurious tones introduced by offset and gain mismatches among the paths only by processing the digital output, without interfering with the operation of the modulator. This solution is als...
