Public-key cryptosystem (PKC) is one of inevitable key technologies in order to accomplish fruitful security applications in ubiquitous computing systems. The ubiquitous computer only has scarce computational resources (like Smart cards, RFID, Sensor Network), however, so that the light weight PKC is necessary for those miniaturized low-power devices. Recently, XTR is considered as one of good ...

Information services are an inherent part of our everyday life. Especially since ubiquitous cities are being developed all over the world their number is increasing even faster. They aim at facilitating the production of information and the access to the needed information and are supposed to make life easier. Until today many different evaluation models (among others, TAM, TAM 2, TAM 3, UTAUT ...

This paper presents the CRISTAL-iSE project as a framework for the management of provenance information in industry. The project itself is a research collaboration between academia and industry. A key factor in the project is the use of a system known as CRISTAL which is a mature system based on proven description driven principles. A crucial element in the description driven approach is that t...

BACKGROUND Controversy exists as to whether disparities in colorectal cancer (CRC) outcomes in African Americans (AAs) are best resolved by screening at age 45 or by proper use of existing guidelines. In 2004, an aggressive colonoscopy-based CRC screening program was implemented throughout New York City. Our goal was to determine the effect of that program on CRC outcomes in our mostly AA popul...

Introduction Fluorine (F) is one of several trace elements receiving much attention owing to its possible harmful effects on health and environment. There are many methods used as the standard method of analysis of total F in soil. These include: ion selective electrode (ISE); X–ray fluorescence (XRF); Ion chromatography; Instrumental Neutron Activation Analysis (INAA); and Atomic and molecular...

1. Abstract We present an incomplete series expansion (ISE) as a basis for function approximation. The ISE is expressed in terms of an approximate Hessian matrix which may contain second, third and even higher order ‘main’ or diagonal terms, but which excludes ‘interaction’ or off-diagonal terms. From the ISE, a family of approximate interpolating functions may be derived. The interpolating fun...

pending on the laboratory. Smaller laboratories analyze the sample on a direct ISE system for Na , K , and Cl , and then forward the remaining sample to the nearest laboratory in the network with the capacity for ultracentrifugation and analysis of the remaining requested test profile. In the larger laboratories equipped with Airfuges, the sample is ultracentrifuged, and all results, including ...

Ion-selective electrode (ISE) based potentiometric gas sensors have shown to be promising analytical tools for detection of chemical vapors. However, such sensors are only capable of detecting those vapors which can be converted into ionic species in solution. This paper describes for the first time a polymer membrane ISE based potentiometric sensing system for sensitive and selective determina...
