INTRODUCTION Impulsive traits are key characteristics in a lot of psychiatric disorders and are part of the "normal" behaviour spectrum. Although impulsivity is a controversial concept, some questionnaires have focused on its "dysfunctional" aspect. The Barratt Impulsive Scale (BIS-10) is the scale the most used to explore impulsiveness, but it does not explore antisocial or nonconform behaviou...

This investigation deals with the transient analysis of the machine repair system consisting of M-operating units operating under the care of single repairman. To improve the system reliability/availability, Y warm standby and S cold standby units are provided to replace the failed units. In case when all spares are being used, the failure of units occurs in degraded fashion. In such situation ...

This paper deals with the Markov modeling and reliability analysis of urea synthesis system of a fertilizer plant. This system was modeled using Markov birth–death process with the assumption that the failure and repair rates of each subsystem follow exponential distribution. The first-order Chapman–Kolmogorov differential equations are developed with the use of mnemonic rule and these equation...

A lökéshullám és az azt előidéző detonációs hullám leírásához három alapvető fontosságú modell ismerete elengedhetetlen. Ezek a gázok állapotváltozóinak ugrásszerű változását okozó lökéshullámok irreverzibilis módon lezajló adiabatikus terjedését leíró Rankine-Hugoniot (RH) modell, valamint az ezen alapuló, a robbanóanyagban letrejövő detonációs hullám terjedését megadó Chapman-Joguet (CJ) mode...

A phase-field model of an oxide relevant to corrosion resistant alloys for film thicknesses below the Debye length L_{D}, where charge neutrality in the oxide does not occur, is formulated. The phase-field model is validated in the Wagner limit using a sharp interface Gouy-Chapman model for the electrostatic double layer. The phase-field simulations show that equilibrium oxide films below the W...

In numerous applications, a hierarchy of models is available to describe the phenomenon under consideration. We focus in this work on general hyperbolic systems with stiff relaxation source terms together with the corresponding hyperbolic equilibrium systems. The goal is to determine the regions of the computational domain where the relaxation model (so-called fine model) can be replaced by the...

A test of flexibility, so widely used that it deserves to be called the classical measure, is hip flexion. It has featured in a variety of guises as the toe-touch test (Weber and Kraus, 1949; Buxton, 1957; Larson, 1974) the sit and reach test (Wells and Dillon, 1952), the femoral trunk angle (Troup, Hood and Chapman, 1968) and supine leg lift (Tanigawa, 1972). Harris (1969) reports on its high ...

The purpose of the present study was to examine the factor structure and the temporal stability of the Chapman psychosis-proneness scales in a representative sample of nonclinical Chinese young adults. The four psychosis-proneness scales evaluated were the Perceptual Aberration (PAS), Magical Ideation (MIS), revised Social Anhedonia (RSAS), and revised Physical Anhedonia (RPAS) scales. The samp...
