For a regular array of hexagonal cells in a suburban outdoor environment, we examined resource allocation schemes in the radio network controller (RNC) for the upand downlink in a UMTS network. In the uplink the noise rise is the parameter of choice. In the downlink the power for different data rates and the connection as a whole serves as the means to control the network. Allocating this resou...

This paper concentrates on the issue of matchmaking in the context of web services. It provides a brief review of the difference between directory services and matchmaking facilities and explains why directories such as UDDI are important but insufficient for web services and need to be complemented with advanced matchmaking facilities. It discusses the requirements that web services place on m...

State-machine sequencing methods in modular 2-phase and 4-phase asynchronous handshake control are compared. Design styles are discussed, and the sequencers are tested against each other using a medium-scale minicomputer test design implemented in FPGAs. Seven 4-phase sequencers are tested. In these comparisons, 2phase control is faster than 4-phase. Within the 4-phase designs, speed is enhance...

One of the challenges of creating a successful project in agile development is the identification of thesequence for developing modules within the program based on the stated requirements. The challengehere is that the difficulty of finding the best solution is a function of the number of modules to becreated plus other factors, giving rise to a NP complete problem. We will start wi...

As the amount of digital video is increasing, efficient w ay s of searching and annotating it according to its content are req uired. T he fi rst step tow ard video index ing is to detect scene changes. A scene is usually defi ned as a seq uence of video frames w ith no significant changes b etw een frames in terms of their visual content. T he simp lest scene cut is rep resented b y a camera b...

During system testing, determining if the observed behaviour of a real–time system is consistent with its requirements specification can be difficult. I propose that a system to check the behaviour against the specification, a monitor, be automatically derived from the requirements documentation. The monitor would model the system requirements as a modified finite state automaton in which the s...

Monitoring seed production in mixed loblolly pinc shortlcaf pine (Pinus taeda L. and Pinus echinata Mill.. respectively) stands may require identifying individual weds hy species. Althuugh lublully pine seeds are UII average Ileavier and larger than thosc of shortleaf pine. there is considerable overlap in these properties for individual seeds. In this study the properties of six seer1 lnrs of ...

Dear Sir, An 11-year-old boy presented to the Sultan Qaboos University Hospital (SQUH), Muscat, Oman, in 2016 with a one-week history of scattered nodular-like erythematous lesions over the arms, petechial rashes over the dorsa of both feet and itchy maculopapular urticarial rashes over both thighs [Figure 1]. He had a high-grade fever which reached 39.5 °C as well as a headache, generalised bo...

It is essential to lubricate the shell since inadequate lubrication leads to defects in the steel product (e.g. longitudinal cracks, sticker breakouts and star cracks). The liquid layer of the slag film, formed between the shell and the mould, lubricates the newly formed shell; the lubrication increases with increasing liquid slag thickness (dl). Lubrication is usually represented by the powder...
