Skew normal mixture models provide a more flexible framework than the popular normal mixtures for modelling heterogeneous data with asymmetric behaviors. Due to the unboundedness of likelihood function and the divergency of shape parameters, the maximum likelihood estimators of the parameters of interest are often not well defined, leading to dissatisfactory inferential process. We put forward ...

Recent advances in computer performance and affordability have accelerated their application to understanding biological phenomena. Computational models are now an integral part of biological and biomedical research. This paper presents a range of examples that illustrate the important role that computational simulation plays in research in the biological and biomedical sciences. 2003 Elsevier ...

Industrial organizations are complex systems` where the interactions among the various functions such as Sales, Distribution, Manufacturing, Materials, Finance, Human Resources and Maintenance have to be man-aged towards a common purpose of delivering the customers satisfaction. However, since most of these or-ganizations have a `Functional Structure`, each function or department works towards ...

OBJECTIVE To evaluate the efficacy and safety of soybean-derived phosphatidylserine (SB-PS) (300 mg/day) in improving cognitive performance in elderly with memory complaints, following a short duration of 12 weeks' SB-PS administration. METHODS SB-PS was administered daily for 12 weeks to 30 elderly volunteers with memory complaints (age range 50-90 years). Cognitive performance was determine...

Road safety index is an important indicator that has been recently introduced as a useful tool to measure the quality of life in many countries and cities. Road safety index is a complex index and it has at least three main components, including road user behavior, vehicle safety, and road infrastructure effects. Many researchers have selected studying road performance from road safety index pe...

Phosphoric acid production companies have a lot of potential hazards that can lead to work accidents. The preventive actions taken by the company is establishing an SHE (Safety, Health and Environment) division appointing safety representative. Based on results patrol record, it turns out there are still unsafe conditions occur value frequency rate in 2021 worth 0.23. This study aims determine ...

Many functions important to realizing the full potential from electronic health records (EHRs) may not be selected by all physicians using EHRs in the ambulatory setting. This article examines the extent to which EHR systems used by Florida physicians include functionalities that the Institute of Medicine has designated as being critical for optimal performance. Results indicate that EHR system...
