geometrical profile (roughness) of joint surfaces influences the behaviour of rock joints under shear loading. with regard to the dilation, there are two models of direct shear test that may simulate the original loading condition existing in the location from where the specimens have been sampled. the first model in which the normal load is constant (cnl) and the discontinuity is free to dilat...

The purpose of this position paper is to introduce the prototype of a design product knowledge representing system which is theoretically guided by our recent work on extending Function-Behaviour-Structure ontology. The basic constructions and data-storing strategies are presented in the paper along with its major interface, thus to give an outline of the working pattern of this system.

The present study investigated behaviour pattern in seventy five patients of electrocardiographically proved coronary heart disease and compared with age and sex matched seventy five normal controls To measure type A-B behaviour in both groups a short rating scale developed by R. W. Bortner was used. It was found that patients of coronary heart disease had significantly higher score on Bortner ...

This paper presents the results of research on the way the network security is affected by the current state of TCP-IP protocol suite behaviour. A number of examples of possible issues are presented. When discussing classes of such issues, it is pointed out that security is affected by the existence of not only incorrect implementations, but also differences in implementations that can be used ...

The performance of concrete primarily depends upon the type and ratio of its constituents, compaction, curing conditions and admixtures used during curing process. Part of this research emphasis to calculate the consequences on strength of concrete when water-cement ratio is constant and the increase in slump occurs with the increase in amount of superplasticizer by percentage. The rest of the ...

In this paper, we investigate the problem of bifurcation control for a delayed logistic growth model. By choosing the timedelay as the bifurcation parameter, we present a Proportional - Derivative (PD) Controller to control Hopf bifurcation. We show that the onset of Hopf bifurcation can be delayed or advanced via a PD Controller by setting proper controlling parameter. Under consideration mode...

in this paper we consider several generalizations of the skew t-normal distribution, and some of their properties. also, we represent several theorems for constructing each generalized skew t-normal distribution. next, we illustrate the application of the proposed distribution studying the ratio of two heavy metals, nickel and vanadium, associated with crude oil in shadgan wetland in the south-...

This paper evaluates an automatic technique for detection of abnormal events in crowds. Crowd behaviour is difficult to predict and might not be easily semantically translated. Moreover it is difficult to track individuals in the crowd using state of the art tracking algorithms. Therefore we characterise crowd behaviour by observing the crowd optical flow and use unsupervised feature extraction...

This paper studies games with ambiguity averse agents, focusing on the relationship between preferences, beliefs over opponent’s preferences, and behaviour in normal form games. Using a carefully chosen 3×2 normal form game we find that a subject’s risk and ambiguity preferences affect the subject’s behaviour in normal form games in the direction suggested by economic theories. In contrast, we ...
