After reviewing the theoretical and empirical literature on Item Response Theory (IRT) and Item-Nonresponse, this study investigates three issues: Firstly, to identify the most appropriate IRT model for understanding item-nonresponse. Secondly, to…
In this paper, we assessed volatility of Ghana’s inflation rates for 2000 to 2018 using the auto-regressive conditionally heteroskedasticity (ARCH), generalized ARCH (GARCH), and the exponential GARCH (EGARCH) models. The inflation data were obtained…
In this study, we jointly modeled longitudinal CD4 count data and survival outcome (time-to-first occurrence of composite outcome of death, cardiac tamponade or constriction) in other to investigate the effects of Mycobacterium indicus pranii…
Sustainable agricultural growth has become an area of interest for many researchers in the quest to increase food production in the midst of an escalating population. However, the evidence remains largely scanty, isolated and devoid of an in-depth…
This paper assesses the teaching and learning experiences of faculty understanding of blending learning in a Higher Education Institutions (HEIs) in Ghana. The driving force for this paper is the transformational agenda of most HEIs to integrate…
To develop an effective control mechanism for any industrial process it is imperative to have a deep and wide ranging understanding of the process itself. This is especially true in the case of a cement grinding circuits, which is a very complex…

This article develops a model of a closed shredding scheme in a ball mill with a separator with high efficiency at a cement plant. Various existing approaches to the development of such models are investigated and a new one is proposed. Based on the…
Effectively managing the grinding process is essential for increasing the productivity of the circuit and the quality of the final product, as well as for significantly reducing production costs. The article is aimed at developing software for…
This article has developed a regularized predictive control based on the l2-norm of the impulse characteristic of the final duration (KIX) with entry restrictions and input speed for the model of a closed grinding scheme in a ball mill with a…
