If quality of service could be provided at the transport or the application layer, then it might be deployed simply by software upgrades, instead of requiring a complete upgrade of the network infrastructure. In this paper, we propose a self-admission control scheme that does not require any network support or external monitoring schemes. We apply the admission control scheme to IP telephony as...

AMD’s Advanced Synchronization Facility (ASF) has been evaluated in earlier work in the context of hardware and hybrid transactional memory, software transactional memory, and lock-free programming. In this work, we describe an extension to ASF for applying it in the area of lock elision (LE), which is now a well established concept in academia, but has not found its way into mainstream micro-p...

often given with prednisolone, would have been necessary. In pregnant women with West African (T. brucei gambiense) stage II disease, either melarsoprol or eflornithine can be used, but neither is effective for East African disease. Although efl ornithine can abort early pregnancies and cause disordered organogenesis (9), the severe encephalopathy associated with melarsoprol makes efl ornithine...

The design concept for the integration of the target and the focusing horn system for the proposed BNL neutrino oscillation experiment is described in this paper. Also presented are issues associated with the functionality and thermo-mechanical response of the selected target intercepting the 28 GeV protons of the 1 MW upgraded AGS beam, the loading and mechanical response of the focusing horn ...

With the advent of Hinjection into thfSBrookhaven AGS, circulating beams of up to 3 x 10 protons at 200 MeV have'been obtained. Rf 2.2 x 1013 and acceleration of 1.73 x 10 fspture of up to the transition energy (8 GeV) and 1.64 x 1013 to full energy (' 29 GeV) has been achieved. This represents a 50% increase over the best performance obtained with H+ injection. The increase in circulation beam...

In this paper we present a parser for Lexical Functional Grammar (LFG) which is characterised by incrementally constructing the cand f-structure of a sentence during the parse. We then discuss the possibilities of the earliest check on consistency, coherence and completeness. Incremental construction of f-structure leads to an early detection and abort ion of incorrect paths and so increases pa...

We present our approach to real-time service-oriented scheduling problems with the objective of maximizing the total system utility. Different from the traditional utility accrual scheduling problems that each task is associated with only a single time utility function (TUF), we associate two different TUFs—a profit TUF and a penalty TUF—with each task, tomodel the real-time services that not o...
