Quality of service QoS support in Mobile Ad-hoc NETworks MANETs i s a c hallenging task. Most of the proposals in the literature only address certain aspects of the QoS support, e.g., QoS routing, QoS medium access control MAC and resource reservation. However, none of them proposes a QoS model for MANETs. Meanwhile, two QoS models have been proposed for(More)
In today fast pace, technologically based world, people need access to information on the go, anywhere at anytime. Because of this, mobile databases are greatly increasing in popularity. Using mobile devices, users can access and modify information without a network connection, and can then synchronize any updates when they get connected. This(More)
Acute myeloid leukemia (AML) is one of the most common acute leukemias in adults and children, yet significant numbers of patients relapse and die of disease. In this study, we identify the dependence of AML blasts on arginine for proliferation. We show that AML blasts constitutively express the arginine transporters CAT-1 and CAT-2B, and that the majority(More)
Cluster validity investigates whether generated clusters are true clusters or due to chance. This is usually done based on subsampling stability analysis. Related to this problem is estimating true number of clusters in a given dataset. There are a number of methods described in the literature to handle both purposes. In this paper, we propose three methods(More)
XML (eXtensible Markup Language) has emerged and is being gradually accepted as the standard for data interchange over the Internet. Since most data is currently stored in relational database systems, the problem of converting relational data into XML assumes special significance. Many researchers have already done some accomplishments in this direction.(More)
− Digital Enhanced Cordless Telecommunications (DECT) [1] is a general radio access technology, which supports local-area mobility only. The interconnection of DECT to Internet is inadequate to support wide-area mobility because IP [2] does not support host mobility between different subnetworks (subnets). This paper describes the interworking of DECT with(More)
In this paper, we present COCALEREX (converting relational to XML) which can address both catalog-based and legacy relational databases. It handles the latter category by first applying the reverse engineering approach described in [2] to extract the ER (Extended Entity Relationship) model from legacy relational databases. This reverse engineering approach(More)
