Second derivative general linear methods (SGLMs) as an extension of general linear methods (GLMs) have been introduced to improve the stability and accuracy properties of GLMs. The coefficients of SGLMs are given by six matrices, instead of four matrices for GLMs, which are obtained by solving nonlinear systems of order and usually Runge–Kutta stability conditions. In this paper, we introduce a...

The formation of clusters in Helbing’s improved model is studied by an iterative method. It is shown that after certain density we will always obtain a density profile which has the structure of a soliton. Its characteristics such as the amplitude and width are determined by the parameters in the model.

Although employee trust in leaders has garnered substantial empirical research, trust between coworkers has been virtually ignored. Extending the work of D. L. Ferrin, K. T. Dirks, and P. P. Shah (2006), the authors examined the role of group leaders, an influential third party in the workplace, on coworker trust formation. The correlates of the extent to which coworkers trust one another were ...

The problem of designing good Space-Time Block Codes (STBCs) with low maximum-likelihood (ML) decoding complexity has gathered much attention in the literature. All the known low ML decoding complexity techniques utilize the same approach of exploiting either the multigroup decodable or the fast-decodable (conditionally multigroup decodable) structure of a code. We refer to this well known tech...
