The impact of slowly digestible sugars in reducing the risk of developing obesity and related metabolic disorders remains unclear. We hypothesised that such carbohydrates (CHO), resulting in a lower glycaemic and insulinaemic response, may lead to greater postprandial fat oxidation rates in subjects with impaired glucose tolerance (IGT). The present study intends to compare the postprandial met...

Three dimensional data is in great demand for the various applications. In order to represent 3D space in details, it is indispensable to acquire 3D shape and texture together efficiently. However, there still lack a reliable, quick, cheap and handy method of acquiring three dimensional data of objects at higher resolution and accuracy in outdoor and moving environments. In this research, we pr...

Despite the ubiquitousness of GPS devices, on board inertial navigation remains important. An IMU like the Sparkfun Ultimate IMU used, contains all the necessary sensors for inertial navigation. These sensors, particularly gyroscopes, are subject to error. An algorithm combining different modalities (acceleration, rotation, and the earth’s magnetic field) to filter this error is developed. The ...

BACKGROUND Biofeedback systems that use inertial measurement units (IMUs) have been shown recently to have the ability to objectively assess exercise technique. However, there are a number of challenges in developing such systems; vast amounts of IMU exercise datasets must be collected and manually labeled for each exercise variation, and naturally occurring technique deviations may not be well...

This paper focuses on evaluating the feasibility of using a low cost Micro Electro Mechanical System (MEMS) – based Inertial Measurement Unit (IMU) integrated with Differential Global Positioning System (DGPS), for land vehicle navigation. The main focus is on position accuracy analysis using a closed loop decentralized GPS/INS integration scheme. A Kalman filter is proposed for the IMU which m...

Surf is an increasingly popular sport and its performance evaluation is often qualitative. This work aims at using a smartphone to collect and analyze the GPS and inertial sensors data in order to obtain quantitative metrics of the surfing performance. Two approaches are compared for detection of wave rides, computing the number of waves rode in a surfing session, the starting time of each wave...

In this paper, performance analysis of hybrid localization based on radio-frequency (RF) and inertial measurement unit (IMU) measurements for a single wireless capsule endoscopy (WCE) traveling the gastrointestinal tract is studied. Specifically, the multiple bodymounted sensors are considered which are located on the front and back of a patient’s medical jacket and form the uniform rectangular...

One precondition for direct sensor orientation with GPS and IMU is the correct sensor calibration. The related parameters as well as the relation between the IMU and the aerial camera (boresight misalignment) have to be determined by conventional bundle block adjustment. During this process a camera self calibration (focal length, principal point, additional parameters etc.) may be performed un...
