At present, although the position theory and algorithm of WSN (Wireless Sensor Network) have been widely researched, however, there still exist many problems on position algorithm needed to be solved, such as low position accuracy and high realization complexity, etc. This paper based on the common trilateral position algorithm uses weighted method to improve the algorithm. The simulation resul...

Although Brazil's twentieth century medicine was strong in the clinical tradition, this was no structural barrier to innovations from the realm of laboratory experiments, contrary to what some historians have argued. The broad debate over the rules of 'experimental methods' reveals a dimension of the struggle waged between proponents of rival medical theories, within a context where dissension ...

Inversion has a disproportionate disruptive effect on the recognition of faces. This may be due to the disruption of holistic or configural encoding employed to recognise upright faces. The paradigm developed by Tanaka and Farah (1993 Quarterly Journal of Experimental Psychology, Section A 46 225-246) was used to investigate the effect of 90 degrees (or orthogonal) rotation on configural encodi...

Although common in the educational and developmental areas, multilevel models are not often utilized in the analysis of data from experimental designs. This article illustrates how multilevel models can be useful with two examples from experimental designs with repeated measurements not involving time. One example demonstrates how to properly examine independent variables for experimental stimu...

OBJECTIVE Although the sociodemographic characteristics of food-insecure households have been well documented, there has been little examination of neighbourhood characteristics in relation to this problem. In the present study we examined the association between household food security and neighbourhood features including geographic food access and perceived neighbourhood social capital. DES...
