A Software Defined Radio test bed using the Gnu Radio project was installed on Unix computers and modified so that estimates of the channel state coefficients were taken for a Multiple Input Multiple output (MIMO) system to take advantage of space time transmission at a frequency of 2.4GHz. Two MIMO techniques were implemented, one based on Alamouti and the other on Space Time Spreading. The technique used to estimate channel coefficients is described. The Bit Error Rate performance was compared, when using Binary Phase Shift Keying, between the two systems and it was found that the STS system performed better …

P-type InAs excited by ultrashort optical pulses has been shown to be a strong emitter of terahertz radiation. In a direct comparison between a p-InAs emitter and conventional thermal radiation sources, we demonstrate that under typical excitation conditions p-InAs produces more radiation below 1.2 THz than a globar. By treating the globar as a blackbody emitter we calibrate a silicon bolometer which is used to determine the power of the p-InAs emitter. The emitted terahertz power was found to be 98±10 nW in this experiment.

This study does not support the notion developed from cross cultural advertising literature that members of a particular cultural group will prefer a particular message advertising appeal if it reflects values that are congruent to its culture. An experimental design is applied to examine whether emotional/ high context appeals (n=120) are more persuasive than factual/ low context appeals (n=124) among target groups from collectivist cultural backgrounds. Analysis of Chinese smokers’ pre-and-post intentions to contact the Chinese Quitline after viewing print advertisements determined that there was no difference between the two ad groups’ shift scores. The common use of direct translations …

Background: Food-based clinical trials are vital to advance the scientific evidence for the impact of food on health. These trials reqUire stringent dietary assessment to substantiate effects. We are evaluating the use of a self-administered computerised dietary assessment (DietAdvice) in a current food based weight loss trial. Objective: This cross sectional study aims to compare data from DietAdvice with diet history (DH) and food record (FR) dietary assessments measured at baseline. Materials and Methods: Baseline data for n=71 overweight (23-60 years, BMI 25-37 kg/m2) participants was utilised. Macronutrient data for matched dietary assessments from n=32 participants was obtained for the …
