Abstract The Lucene Server project is an attempt to extend the Jakarta Lucene tool with server capabilities. Lucene is a robust Java API that enables you creating indexes from text sources and perform powerful searches on these indexes. With Lucene, creating an index must be done programmatically ...

Application Note Abstract The unique configuration of the PSoC&reg switched capacitor blocks allows construction of a programmable bipolar current source. A detailed explanation of this function is provided demonstrating how to build a programmable current source using a couple basic PSoC User Modul ...

Abstract-The effect of the companding process on QAM signals has been under investigation for the past several years. The compander, included in the PCM telephone network to improve voice performance, has an unusual affect on digital QAM data signals which are transmitted over the same channel. The ...

Abstract. The main aim of this research is to improve communication between student and teacher by using the developing mobile information technologies. Implementing such technologies in education may help to develop learning environments to share the knowledge among students and increase their moti ...

Abstract—The contourlet transform is a new two-dimensional extension of the wavelet transform using multiscale and direc- tional &#64257 lter banks. The contourlet expansion is composed of basis images oriented at various directions in multiple scales, with &#64258 exible aspect ratios. Given this ...

Abstract: The MAX3108 is a complete high-performance universal asynchronous receiver-transmitter (UART) in a tiny 2.1mm ×

The Radio Interface Layer is the name for an interface that was developed especially for the Pocket PC Phone Edition. It is meant to abstract the interface with a phone/modem device. To achieve this it is closely modelled after the GSM AT command interface. Unfortunately the API was not published of ...

Abstract: The MAX9930–MAX9933 family of RF controllers and detector can be used in a wide variety of applications. Anideal application is cable television (CATV) over fiber, where either a RF controller or a RF detector controls the gain of atransimpedance amplifier (TIA). This application n ...

Abstract: The DS4830 optical microcontroller's analog-to-digital converter (ADC) offset can change with temperature and gainselection. However, the DS4830 allows users to measure the ADC internal offset. The measured ADC offset is added to the ADCoffset register to nullify the offset error. Th ...
