Abstract In this paper, an incremental quaternion interpolation algorithm is introduced. With the assumption of a constant interval between a pair of quaternions, the cost of interpolation algorithm is significantly reduced. Expensive trigonometric calculations in Slerp are replaced with simple linear combination arithmetic. The round-off errors and drifting behavior accumulated through increme...

Channel assignment strategies for use with a high altitude platform, spot beam architecture are examined. A novel power roll-off approximation is derived to allow terrestrial simulation tools to be used, and simulation performance is compared with a theoretical lower bound derived from the Engset distribution. It is shown that the use of cell overlap considerably enhances the blocking probabili...

Cruickshank and Collins [2] ‘Advancing Leadership in Sport: Time to Take Off the Blinkers?’ has created something of a furore around the effectiveness and suitability of dark leadership traits and behaviours. This paper attempts to clarify some of the conceptual issues discussed within their paper, while also redressing a number of literary misrepresentations. Finally, the potential limitations...

One of the main principles of social networks is the concept of homophily, defined as the tendency to form and sustain contacts with similar actors. Studies have shown that homophily can be based on race and ethnicity, on informal or ascribed status (e.g., gender, age, religion, education, occupation), or on shared values and beliefs. In this talk, we will investigate the Persian language blogo...

BLUe’s format is an independent set of TEX macros to assist self-publishing authors with creating, formatting, exchanging and maintaining compuscripts. It comes with a user’s guide and TEXnical documentation. The format builds upon manmac, upon functionalities provided in the TUGboat styles, and upon experience gained by the AMS in TEX formatting. off-off for the time being. The macros are shar...

This paper draws attention to the risk of rounding error in the numerical evaluation of steady-state probabilities for the M/M family of queues. A method for avoiding the risk is presented which is easy to program for calculation in practice.
