Docking of mobile robots requires precise position measurements in relation to the docking platform to accomplish the task successfully. Besides, the pose estimation of the robot with the sensors in an indoor environment should be accurate enough for localization and navigation toward the docking platform. However, the sensor measurements are entitled to disturbances and measurement uncertainties.

Caches today are an important part of mitigating the performance gap between processors and memory which has increased during the last 50 years. Cache policies are vital for the performance of caches and their mission is to select the data which should be contained in the cache and are therefore important for the performance of processors. Graphics processors are very memory bandwidth intensive an

This study investigates how the usage of a Kenyan mobile banking service called M-pesa affects women empowerment and if different forms of usage have a significant effect. This is done through the distribution of a questionnaire in Nairobi, Kenya. Through both a OLS and a 2SLS model the answers about a person’s usage of M-pesa is then run against a constructed a women empowerment index and against

In recent years, the market for mobile applications has continuously grown in size, and appears to continue to grow. This means greater competition among app developing companies as the users expect applications with high usability and a great user experience. To assess these properties the companies can perform usability evaluations. However, practicing traditional usability evaluation methods ca

A real time visualisation method, to be used in mobile gamma-spectrometric search operations using standard detector systems is presented. The new method, called deviation display, uses a modified waterfall display to present relative changes in spectral data over energy and time. Using unshielded (137)Cs and (241)Am point sources and different natural background environments, the behaviour of the

Despite the clear restrictive guidelines about the use of modern handheld devices among children younger than 2 years, parents are seen to extensively use these devices with their infants. However, parents’ perceptions in this regard remain unclear and underexplored especially, in the context of South Asian cultures such as Pakistan. This qualitative study aims to explore parents’ perceptions rega

PURPOSE: This study describes the effects of a mobile geriatric acute team (GAT) treating acutely ill geriatric patients in their homes. GAT offered more advanced diagnostic and treatment options than are normally available to primary-care led mobile teams. The aim of this study was to evaluate if interventions by GAT had effect on the number of emergency department (ED) visits, hospitalisations,

The purpose of this thesis was to investigate hardware usability issues on modern mobile phones, in order to form design guidelines and eventually a concept design proposal focusing on high usability. The project had a Universal Design focus, and the goal was to design a concept that fits as many users as possible. Initially a market analysis was performed in order to find out what phones focusin

Twenty-six patients were operated because of osteo-arthritis of the trapeziometacarpal joint. After excision of the trapezium, they were randomized to receive either a Swanson silicone trapezium implant or a tendon interposition arthroplasty using a strip of the abductor pollicis longus tendon (APL). No infection or clinical silicone synovitis occurred and no major radiographic cyst formation was

In a method and a mobile communications receiver for performing signal measurements, signal measurement data is received from at least one base station during at least part of a measurement period. Each measurement period comprises a number of non-equidistant snapshot measurement windows during which the receiver receives signal measurement data. At least one average signal strength value of the s
