This text will help students understand the concepts involved in CIM and it will provide a foundation for applying those concepts in actual industrial situations. CIM is. With design of products changing frequently, and functional requirements becoming more demanding, batch production of high precision components has become a necessity. The. Provides(More)
Speaker recognition is the process of recognizing the speaker based on characteristics such as pitch ,tone in the speech wave. Background noise influences the overall efficiency of speaker recognition system and is still considered as one of the most challenging issue in Speaker Recognition System (SRS). In this paper mel-frequency cepstral coefficients(More)
—A novel channel-allocation method that allows reduction of the four-wave mixing (FWM) effect while maintaining bandwidth efficiency is presented. It is composed of a fractional bandwidth-allocation algorithm, taking into consideration the use of parameters with distinct differences. This proposed technique allows the computation of an optimal(More)
A wavelength conversion technique which can convert an input signal to many wavelengths simultaneously without any probe laser is proposed. 622Mb/s one-to-six wavelength conversion and multicast in a bus network are demonstrated. I. Introduction All-optical wavelength converters are important components to increase the flexibility and capacity of(More)
With the recent advances in smart phones and their ease of availability to common man, researchers are exploring efficient algorithms for face recognition on mobile devices for entertainment applications. The limited memory and processing power on mobile devices pose significant challenge to the satisfactory of popular face recognition algorithms like LBP,(More)
Several environmental toxins with toxic effects to the bone marrow have been identified. Pathology associated with lead intoxication is due to the cellular damage mediated by free radicals. In the current study, we examined the effect of Etlingera elatior extract on lead-induced changes in the oxidative biomarkers and histology of bone marrow of rats.(More)
Expansive clayey soils are highly moisture sensitive with respect to stress, deformation and strength. These soils exhibit extreme variation in deformation such as heaving, loss of shear strength under certain Moisture Content and settlement and shrinkage as the Moisture Content alters. Swelling is the process of increase in volume of soil that occurs(More)
Lead is known to disrupt the biological systems by altering the molecular interactions, cell signaling, and cellular function. Exposure to even low levels of lead may have potential hazardous effects on brain, liver, kidneys and testes. The efficacy of Etlingera elatior (torch ginger) to protect hepatotoxicity induced by lead acetate was evaluated(More)
An algorithm for WDM channel allocation, based on the concept of Optimal Golomb Ruler (OGR), is proposed. This algorithm enhances system performance by locating an allocation set, where the degradation caused by the effects of interchannel interference and Four-Wave Mixing (FWM) is minimal. Two sets of simulation were performed on an 8x10Gbpschannel system(More)
An extremely short long-period grating (LPG) with strong resonance has been developed in a large-mode-area photonic crystal fiber (PCF) by use of the heat source of a CO2 laser. We believe that such a LPG in pure silica PCF is the first example to be obtained with the point-by-point technique. The fabrication method is simple and repeatable. The resulting(More)
