Investigations were carried out to evaluate the performance of direct injection diesel engine with medium grade low heat rejection (LHR) combustion chamber and 3 mm air gap insulated piston, 3 mm air gap insulated liner, and ceramic coated cylinder head [ceramic coating with the thickness of 500 µ was made on the inside portion of the cylinder head].The engine had different operating conditions...

This paper reports on a study of the temporal characteristics of phonological error repair in spontaneous Dutch speech, with a focus on how the articulation rate of the correct target word production — the repair — compares to that of the preceding erroneous target word attempt — the reparandum. The study is motivated by two findings from recent independent studies: first, that selfrepair is ge...

We do some simple calculations involving buffers in discrete time process algebra with relative timing. Note: Dedicated to prof.dr. F.E.J. Kruseman Aretz, on the occasion of his ‘afscheidscollege’.

PURPOSE To examine the effect of recall timing on training-session rating of perceived exertion (sRPE) in a population of athletes well familiarized with the method and procedures during a 5-d training microcycle. METHODS Fifty-one top-class field referees (FRs) (age 38.4 ± 3.3 y, height 181 ± 5.6 cm, body mass 76.8 ± 6.8 kg, body-mass index 23.4 ± 1.7 kg/m2, body fat 20.4% ± 3.6%, internatio...

We address three related issues on timing characterization of combinational modules. We first introduce a new notion called timing safe-replaceability as a way of comparing the timing characteristics of two combinational modules formally. This notion allows us to determine whether a new module is a safe replacement of an original module in terms of timing under any surrounding environment. Seco...

This paper presents a design flow for timed asynchronous circuits. It introduces lazy transitions systems as a new computational model to represent the timing information required for synthesis. The notion of laziness explicitly distinguishes between the enabling and the firing of an event in a transition system. Lazy transition systems can be effectively used to model the behavior of asynchron...

This paper proposes a joint timing synchronization and channel estimation scheme for communications systems with multiple transmit antennas based on a well-designed training sequence arrangement. In addition, a generalized maximum-likelihood (ML) channel estimation scheme is presented, and this one-shot scheme is applied to obtain all channel impulse responses (CIR) from different transmit ante...

Several studies document lengthening of the frost-free season within the conterminous United States (U.S.) over the past century, and report trends in spring and fall frost timing that could stem from hemispheric warming. In the absence of warming, theory and case studies link anomalous frost timing to atmospheric circulation anomalies. However, recent efforts to relate a century of observed ch...

The reliability of surface electromyographic (sEMG) variables during swallowing determines the potential usefulness of these measures in swallowing assessment and treatment. This study aimed to establish the reliability of the sEMG measures of the swallowing function of muscles during different swallowing conditions in healthy young and old volunteers. Two groups of volunteers (24 older adults,...
