The Health Insurance Portability and Accountability Act (HIPAA) has set privacy and security regulations for the US healthcare industry. HIPAA has also established principles for security standards that global e-health industry tends to follow. In this paper, a hybrid public key infrastructure...

The critical scaling and universality in the short-time dynamics for spin models on a two-dimensional triangular lattice are investigated by using a Monte Carlo simulation. Emphasis is placed on the dynamic evolutions from fully ordered initial states to show that universal scaling exists...

Many supply chains contain both forward and reverse logistics flows where forwarders are often asked to manage forward and reverse logistics activities in a cost-efficient manner. Reverse logistics jobs are different from forward logistics jobs, apart from the physical movement directions, and...

Estimating seasonal variations in demand is a challenging task faced by many organisations. There may be many stock-keeping units (SKUs) to forecast, but often data histories are short, with very few complete seasonal cycles. It has been suggested in the literature that group seasonal indices...

The discrete-time G/D/1 queues with serially correlated batch arrivals and unit service times have wide applications in modern telecommunication systems. Despite the rich literature in their performance analysis, no simple formula on the relation between system size and sojourn time is known. We...

A review of the innovation and diffusion literature indicates a considerable amount of research, where attention is given to a range of features which may support integration technologies adoption. However, some literature suggests that the findings derived from the study of large enterprises...
