Ontology search interfaces can benefit from the latest information retrieval advances. This paper introduces a Conjunctive Ontology Browser and Explorer (COBE) for searching and exploring SNOMED CT concepts and visualizing SNOMED CT fragments. COBE combines navigational exploration (NE) with direct lookup (DL) as two complementary modes for finding specific SNOMED CT concepts. The NE mode allow...
Cooperative system is a tendency in the future communications because it provides a spatial diversity to improve the system performance. Three strategies including Amplify-and-Forward (AF) mode, Decode-and-Forward (DF) mode and Compress and Forward (CF) mode could be candidate to be employed in the system. This work considers the cooperative communication systems in DF Mode. The scenario includ...
Like many wide field gamma-ray telescopes, the Milagro observatory has a highly variable point spread function (PSF), dependent upon the characteristics of the incoming photon. Because of the large variations in the PSF, a binned transient search technique is not optimal, and maximum likelihood can be computationally unfeasible. I have expanded upon the Gaussian weighting technique [1] to devel...
The GOLF instrument, as its name implies, was designed to optimise the possibility of measuring low frequency oscillations, in the range of the g-modes and the lower p-modes. The high stability of the instrument , combined with a continuity of data close to 100 % has contributed to providing a velocity time series in which the instrumental noise is indeed extremely low. However, in the region o...
Accurate CCD observations of three Cepheids in the SMC were made with the purpose of confirming their nature of second overtone mode Cepheids. The stars were suspected pulsating in the second overtone mode owing to the unusual light curve and short period reported by Payne-Gaposchkin & Gaposchkin (1966). The analysis of the new data shows that for two stars the previous periods are wrong, and i...
This paper addresses a general class of nonpreemptive resource-constrained project scheduling problems in which activity durations are discrete functions of committed renewable and nonrenewable resources. We provide a well known 0±1 problem formulation and stress the importance of themodel by giving applications within production and operationsmanagement. Furthermore, we prove that the feasibil...
Intra-frame mode selection and inter-frame mode selection are new features introduced in the H.264 standard. Intra-frame mode selection dramatically reduces spatial redundancy in Iframes, while inter-frame mode selection significantly affects the output quality of P-/Bframes by selecting an optimal block size with motion vector(s) or a mode for each macroblock. Unfortunately, this feature requi...
Drawing on Skellam׳s (1958) work on sampling animal populations using transects, we derive a behavioral ecological model of the choice between sit-and-wait and active-search hunting. Using simple, biologically based assumptions about the characteristics of predator and prey, we show how an empirically definable parameter space favoring active-search hunting expands as: (1) the average rate of m...
