Dynamic translinear (DTL) circuits use the exponential inputoutput relation of the transistor as a primitive for the synthesis of electronic circuits. As a consequence the analysis of the dynamic behaviour of this type of circuits in the presence of parasitics results in analyzing dynamic nonlinear circuits. There are three different approaches that can be applied: the linear time-invariant (LT...

With due attention to the fact that the local and foreign vehicle industries are changing and modifying the previous designs in order to produce new designs, the components of self-propelled are to be differently analyzed. Static and dynamic analysis is one of them. In this paper, chassis and body of a o-457 bus were studied and analyzed under finite element method (using ANSYS).This process wa...

The variation law of satellite clock bias (SCB) can be regarded as a grey system because the spaceborne atomic is very sensitive and vulnerable to many factors. GM (1,1) model core foundation system, which has been highly valued successfully applied in SCB prediction since its production. However, there are still some problems further studied such lack stability effect practical application. In...

Verification bias arises in diagnostic test evaluation studies when the results from a first test are verified by a reference test only in a non-representative subsample of the original study subjects. This occurs, for example, when inclusion probabilities for the subsample depend on first-stage results and/or on a covariate related to disease status. Reference standard bias arises when the ref...

BACKGROUND AND OBJECTIVES Previous research suggests that attention bias toward threat contributes to the development and maintenance of anxiety. The current study extends this work by mapping the neural correlates of experimentally-induced changes in attention bias. The study examines both behavioral and psychophysiological changes associated with experimentally-induced changes in threat bias....

In this paper, the self-alignment for stationary strapdown inertial navigation system (SINS) is formulated as an optimization problem, and two gradient descent optimization-based SINS methods (GD1 GD2) are proposed. The highlight lies in that quaternion-based objective functions firstly to solve problem. Different from conventional initial alignment methods, we construct a function using gravit...

infiltration plays an important role in surface and subsurface hydrology and it is a key factor in the rainfall and runoff equations. the use of new approaches that have no limitations of common theoretical and empirical methods to determine infiltration relationships, will minimize the necessity of time consuming and costly experiments to determine permeability values and will make it possible...

We report results of numerical simulations for a model of generation of orientation selectivity in macaque striate cortex. In contrast to previous models, where the initial orientation bias is generated by convergent geniculate input to simple cells and subsequently sharpened by lateral circuits, our approach is based on anisotropic intracortical excitatory connections which provide both the in...
