Within the framework of Landau-de Gennes theory for nematic liquid crystals, we study temperature-induced isotropic-nematic phase transition on a spherical shell. Below critical temperature, thin layer coating microscopic particle exhibits non-uniform textures due to geometrical frustration. We find exact value threshold temperature and determine exactly at by means weakly nonlinear analysis. T...

background: motivation is a driver to health worker performance in most ghanaian hospitals. in view of this, ghana’s ministry of health has rolled out enough motivational policies to accentuate work performance of health workers. objective: the focus of this study was to examine the impact of motivation and identify how intrinsic and extrinsic motivating factors affect the work performance of h...

considerable attention has been given to the identification of key forms of reward and its linkage to employee engagement. for this purpose following study aims to uncover the influence of extrinsic and intrinsic rewards on employee engagement in the public sector of uganda. a sample of 184 public sector employees was randomly selected and taken from gulu district. a quantitative approach based...

We prove Berger type theorems for the normal holonomy Φ (i.e., the holonomy group of the normal connection) of a full complete complex submanifold M both of Cn and of the complex projective space CP n. Namely, (1) for Cn, if M is irreducible, then Φ acts transitively on the unit sphere of the normal space; (2) for CP n, if Φ does not act transitively, then M is the complex orbit, in the complex...

In recent decades, "Public Sphere" is one of the most important concepts in political science. Jurgen Habermas the famous thinker in this approach is the first to use this concept in critical thinking, where he demonstrates how networking is used for communicative actions. Habermas has not included the Internet as an important part of his thought process in the "public sphere", however, I think...

We propose an extrinsic Bayesian optimization (eBO) framework for general problems on manifolds. algorithms build a surrogate of the objective function by employing Gaussian processes and utilizing uncertainty in that deriving acquisition function. This represents probability improvement based kernel process, which guides search process. The critical challenge designing manifolds lies difficult...
