Control Part

Hospital patients, persons of old age, and physically handicapped persons need wheelchairs and helpers. When a helper carries one of these persons, he/she must be attend on the person ridden on a wheelchair. The helpers are busy and have a lot of work. Patients without helpers grow very tired navigating their wheelchairs. To help, we propose an autonomous fuzzy navigation system for an automatic control of a wheelchair. This system consists of a navigation planning part, a navigation control part, and an environment recognition part. In this paper, we describe an intelligent wheelchair with a fuzzy navigation system and discuss experimental results.

Brand Relationship

Back in Chapter 4, we propose a model which attempts to encapsulate the antecedents of a brand relationship and subsequently its influence towards brand loyalty. The findings suggest that brand personality, brand trust, and brand salience are important antecedents to create a brand relationship in the children's market. Meanwhile, brand loyalty was identified as the consequence of a brand relationship, autobiographical memory, and habituation. In this chapter, we are going to expand this discussion by measuring variables concerning future anticipation, ritual, autobiographical memory, and living brand using fuzzy logic on children within the 10-12 years old age group who are assumed to be mature enough to understand and reply to simple direct questions. Ultimately, we would like to see whether the two constructs of future anticipation and ritual are (among) the antecedents of a living brand.

Navigation Control

This chapter proposes a two-input-and-one-output fuzzy controller for a two-wheeled mobile robot. The robot moves following a hybrid plan based on Genetic Algorithms and Constraint Satisfaction Problem techniques. The path yielded by this hybrid plan is structured by artificial beacons. In each position of these beacons, the current velocity of the controlled robot is by itself an input for the fuzzy controller. The second input is the time delay between the current position and the next sub goal to be reached. The proposed fuzzy controller aims to converge the time delay between positions in the path tracking closely to a time window. It gives the appropriate acceleration so that the time delay becomes closer to the time window.

Registrar Training

The co-existence of physical and psychiatric illness in so much of the elderly population poses diagnostic and therapeutic problems for psychiatrists, geriatricians and general practitioners alike, with the presence of physical illness strongly influencing and sometimes limiting the options for treatment of the psychiatric illness. Recognition of this has resulted in the Section of Old Age Psychiatry of the Royal College of Psychiatrists recommending that senior registrar training in old age psychiatry should include a one month attachment to an approved geriatric medicine unit.
