This paper presents the development of a vision-based neuro-fuzzy controller for a two axes gimbal system mounted on a small Unmanned Aerial Vehicle (UAV). The controller uses vision-based object detection as input and generates pan and tilt motion and velocity commands for the gimbal in order to keep the interest object at the center of the image frame. A readial basis function based neuro-fuz...

Vegetarianism is an old classic eating behavior that leads to lessening of several health risk factors. Vegetarian diet is reported to improve control of blood glucose concentration, to lower insulin requirement and to aid in weight control in diabetic patients. However, there is no evidence for the prevalence of diabetes mellitus to be significantly lower in vegetarians than in non-vegetarians...

How much does language influence how we think? How far are the categories of our language contingent and culture-specific? Few questions are of greater significance to the social sciences. In this paper we attempt to demonstrate that linguistic semantics can address these questions with rigour and precision, by analysing some examples of cultural 'key words' in several languages. We want to arg...

This study explored touchscreen keyboards using high precision touchscreen strategies. Phase one evaluated three possible monitor positions: 30, 45, and 75 degrees from horizontal. Results indicate that the 75 degree angle, approximately the standard monitor position, resulted in more fatigue and lower preference ratings. Phase two collected touch bias and key size data for the 30 degree angle....

Integrating the advantage of magnetic bearings with a double gimble control moment gyroscope (DGCMG), a magnetically suspended DGCMG (MSDGCMG) is an ideal actuator in high-precision, long life, and rapid maneuver attitude control systems. The work presented here mainly focuses on performance testing of a MSDGCMG independently developed by Beihang University, based on the single axis air bearing...

A common challenge in developing small-satellite-based Earth-observation (EO) missions is getting the data to the ground. Typically, most satellites download data via space-to-ground radio-frequency (RF) links, communicating directly with fixed ground stations as the satellites fly within range. For many next-generation EO missions, such as hyperspectral imaging or SAR missions, the volume of d...

BACKGROUND Somatisation is particularly challenging in multicultural contexts where patients and physicians often differ in terms of their illness-related beliefs and practices and health care expectations. This paper reports on a exploratory study aimed at better understanding how asylum seeker and refugee patients from the former country of Yugoslavia who were identified by their physicians a...
