It is well known that constraint logic and functional-logic programming languages have many advantages, and there is a growing trend to develop and incorporate effective tools to this class of declarative languages. In particular, debugging tools are a practical need for diagnosing the causes of erroneous computations. Recently [1], we have presented a prototype tool for the declarative diagnos...

When estimating the Doppler frequency, it is common to use a covariance approach. This is especially true for applications such as underwater current profiling . The early developers of this technology made the assumption that the backscattered signal obeyed Gaussian properties. Based on that, a covariance approach have been used for the estimation of the center frequency I the Doppler signal. ...

Multipoint relays o er an optimized way of ooding packets in a radio network. However, this technique requires the last hop knowledge: to decide wether or not a ooding packet is retransmitted, a node needs to know from which node the packet was received. When considering broadcasting at IP level, this information may be di cult to obtain. We thus propose a scheme for computing an optimized conn...

P2 is a new and exciting system that permits declarative implementations of overlay networks. The recently published work cites reasonable implementations and performance for two protocols, Chord and Narada. Our work evaluates P2 through an implementation of a third protocol, the Paxos consensus protocol. P2’s declarative language Overlog, admitted a smooth and readable implementation of the Pa...

Saccadic adaptation is the motor learning process that keeps saccade amplitudes on target. This process is eye position specific: amplitude adaptation that is induced for a saccade at one particular location in the visual field transfers incompletely to saccades at other locations. In our current study, we investigated wether this eye position signal corresponds to the initial or to the final e...

Spinal Cord Injury (SCI) is damage to spinal cord, which is categorized according to the extent of functional loss, sensation loss and inability of the subjects to stand and walk. The patients use two transportation systems including orthosis and wheelchair. It was claimed that standing and walking bring some benefits such as decreasing bone osteoporosis, prevention of pressure sores, and impro...

Three wether sheep equipped with re-entrant cannulae at the proximal duodenum and terminal ileum were given dried cocksfoot in the chopped or ground form and the samples of duodenal and ilea! digesta and faeces obtained for both diets were analysed for individual long-chain fatty acids. The total quantities of fatty acids entering the proximal duodenum (15.2 and 15.4 g/24 h on chopped and groun...

Thirty-two crossbred wether lambs (initial live-weight 31 kg) were fed on a diet (metabolizable energy (ME) 12.8 MJ/kg) ad lib. (ADLIB) or restricted to maintain body-weight (MAINT) for a 21 d period. On days 0, 7, 14 and 21, four lambs per treatment were slaughtered, visceral organs weighed and tissues sampled. During the 21 d period, ME intake in ADLIB lambs increased quadratically with an av...

It is not known if the ruminant animal gastrointestinal tract (GIT) can oxidise essential amino acids (AA) other than leucine. Therefore, the oxidation of four essential AA (leucine, lysine, methionine and phenylalanine), supplied systemically as labelled 1-13C forms, was monitored across the mesenteric-drained viscera (MDV; small intestine) and portal-drained viscera (PDV; total GIT), as part ...
