Quality of service (QoS) support in Mobile Ad-hoc NETworks (MANETs) is a challenging 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(More)
I n t r o d u c t i o n The word "clustering" (unsupervised classification) refers to methods of grouping objects based on some similarity measure between them. Clustering algorithms can be classified into four classes, namely Partitional, Hierarchical, Density-based and Grid-based [8]. Each of these classes has subclasses and different corresponding(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)
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)
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)
LTE-Advanced (Parkvall et al., 2011; 3GPP TR36.814) is the successor of LTE (Long Term Evolution), which is specified by the Third Generation Partnership Project (3GPP). LTEAdvanced can provide downlink and uplink peak rates up to 1 Gb/s and 500 Mb/s, respectively, in 100 MHz of bandwidth. Similar to its predecessor, LTE-Advanced is an Orthogonal Frequency(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)
1 CWC is a national R & D Centre funded by the Singapore National Science and Technology Board. Abstract − 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(More)
