In an earlier paper, we designed a similarity based video retrieval system. Queries are speciied in a language called Hierarchical Temporal Language (HTL). In this paper, we present several extensions of the HTL language. These extensions include queries that can have the negation operator and any other logical and temporal operators such as disjunction. EEcient algorithms for processing querie...

A metering scheme is a method by which an audit agency is able to measure the interaction between clients and servers on the web during a certain number of time frames. Naor and Pinkas 7] considered metering schemes in which any server is able to construct a proof to be sent to the audit agency if and only if it has been visited by at least a number, say h, of clients in a given time frame. In ...

The observation that near-threshold low-contrast visual distractors can equally influence perceptual state and goal-directed motor responses was recently taken as an argument against a sharp separation between a conscious vision for perception and an unconscious vision for action. However, data supporting the dual visual system theory have principally involved high-contrast stimuli. In the pres...

There is little standardization of how to measure cycling gross efficiency (GE). Therefore, the purposes of these studies were to evaluate the effect of: i) stage duration, ii) relative exercise intensity, iii) work capacity and iv) a prior maximal incremental test on GE. Trained subjects (n=28) performed incremental tests with stage durations of 1-, 3-, and 6-min to establish the effect of sta...

We study an overlapping generations model of human capital accumulation with threshold effects using regional data for West Germany. Our basic goal is to shed light on what makes German regions grow. The paper finds that the relative income distribution appears to be stratifying into a trimodal distribution. Thus, application of the threshold model to a real world case, here West Germany, shows...

The dimpling in the CuO2 planes of overdoped Y1−yCayBa2Cu3 O6.96−6.98, (y = 0.02−0.2) has been measured by x-ray absorption-fine-structure spectroscopy (Y-K EXAFS). A step-like decrease around 12% Ca indicates a percolation threshold for distorted sites of 5 cells, and thus phase segregation. We conclude the charge carriers added by substitution of Y by Ca to be trapped at the Ca sites and thei...

Variable-threshold threshold elements (V-T threshold elements) are threshold elements in which the weights are fixed while the threshold may be varied. When the threshold is varied, a set of functions is generated. A concept termed complete uniformity, analogous to complete monotonicity, is shown to be a necessary condition for a set of functions to be realizable by a single V-T threshold eleme...

Three basic auditory abilities were measured in 21 visually impaired college students and 21 sighted college students with same age and gender composition. The measurement consists of the hearing level of 11 tones, masking thresholds of same 11 tones masked by 80dB narrow band noises and frequency difference limens (FDL) of 3 tones. The results indicate that all the three auditory abilities of ...

The objective of the study was to verify whether young males' balance was affected by 30min prolonged treadmill running (TR) at individual ventilatory (IVT) and anaerobic (IAT) thresholds in recovery time. The VO2max, IAT and IVT during an incremental TR were determined. Mean displacement amplitude (Acp) and velocity (Vcp) of center of pressure were recorded before (pre) and after (0min post; 5...

Realistic network-like systems are usually composed of multiple networks with interacting relations such as school-enterprise research and development (R&D) collaboration networks. Here we study the percolation properties of a special kind of that R&D collaboration networks, namely institute-enterprise R&D collaboration networks (IERDCNs). We introduce two actual IERDCNs to show their structura...
