This short paper gives an introduction into electronic product catalogs and classification systems such as eCl@ss or UN/SPSC used in this domain. The role of classification systems to foster interoperability of catalog based enterprise systems is explained as well as problems that occur. Afterwards an approach is presented that aims in compensating these problems with the help of a mediating sy...

a two server queueing system with single and batch service is considered in this paper. the arrival process is assumed to be poisson and the service rate follows an exponential distribution. server-i serves the customers in both single and batch service, while server-ii serves the customers in batch service only. the laplace transform of the transient and steady state behavior of the model is c...

in this paper, we present a novel algorithm for vanet using cloud computing. we accomplish processing, routing and traffic control in a centralized and parallel way by adding one or more server to the network. each car or node is considered a client, in such a manner that routing, traffic control, getting information from client and data processing and storing are performed by one or more serve...

AMBAR es un proyecto que busca el desarrollo de un Sistema Generador de AMBientes de Enseñanza-ApRendizaje Constructivistas basados en Objetos de Aprendizaje (OA). Los ambientes generados por AMBAR deben cumplir con atributos como la interoperabilidad, reusabilidad, accesibilidad y escalabilidad, y esto solo se logra vinculándolos a estándares. En este sentido, se encuentra el IMS Learning Desi...

A new framework for support of reliable multipoint communication in ATM networks is presented. It is based on a new adaptation layer type, called the Reliable Multicast ATM Adaptation Layer (RMC-AAL), and on a new network element, called the Group Communication Server (GCS). A set of error control mechanisms tailored for multipoint communication are integrated into RMC-AAL and GCS. Error contro...

The biological data explosion of the 'omics' era requires fast access to many data types in rapidly growing data banks. The MRS server allows for very rapid queries in a large number of flat-file data banks, such as EMBL, UniProt, OMIM, dbEST, PDB, KEGG, etc. This server combines a fast and reliable backend with a very user-friendly implementation of all the commonly used information retrieval ...

In this paper, we recommend and promote global standards of the e-Trade process on the basis of ebXML & web services. For the ebXML Frameworkbased e-Trade to be facilitated, it is urgent for each country to implement and use national ebXML registry and standardize electronic documents, electronic catalog and electronic payment. In UNCEFACT, ebXML-based UN Central Registry & Repository is in the...

E-commerce server reliability is critical, as downtimes cost an average of $10,000 per minute [40]. Commercial web server development today is done with fairly generic programming languages, like Java, Perl, and C#. The generality of these languages, while permitting a wide range of target applications, makes it difficult to guarantee reliability: dynamic type errors, race conditions, and resou...
