A new course entitled "Methods of Operations Research (OR)" was introduced at the Department of Applied Mathematics of Stellenbosch University during the second half of 2001.The aim of this course was to introduce students of OR to the trauma of mathematical modelling in real-world scenarios, instead of merely teaching them a number of theoretical
Background: Numerous plants and plant isolates have been widely reported for the treatment of arthritis.Berberine, a cationic flavonoid, obtained from Berberis aristata DC.(Berberidaceae) has been well reported for the treatment of arthritis.The lipid-based vesicular system including invasomes overcome the stratum corneum barrier and can effectivel
The impact of the work environment on employees has been well researched, with little focus on the pathways of such relationships.This study aimed to examine whether workplace incivility and personality predict workplace stress and organizational citizenship behavior (OCB).The role of John Henryism (JH), Probabilistic Orientation (PO), work self-ef
Traditional security surveillance detection relies on post-event forensics or is hosted on a backend server, making it impossible to identify behaviors filmed in the field online.This paper proposes the Smart City Security System (SCSS) for detecting anomalous activity in public locations online.SCSS combines the DeepSORT and YOLOv4 algorithms to g
An investigation of the system efficiency requires a special approach in terms of its level, content and interrelations with an external environment.In this regard logistic systems are rather complicated that consist of a number of service sub-systems and designed at various levels.Such system complexity requires a development of an efficient mecha
