Real-time and on-line monitoring of wastewater quality is a subject of growing concern both in the United Kingdom and internationally. Global organic load parameters are traditionally used to define wastewater characteristics and to demonstrate that a wastewater treatment plant meets statutory law. However these measurements are mainly based on sample collection and retrospective analysis which can be time consuming. Existing on-line instruments remain limited by environmental factors, short lifetimes and fouling problems due to the harsh environment in which they have to be located. The recent availability of commercial sensor array instruments could offer a rapid and relatively simple technique for non-invasive monitoring.

In this thesis the problem of load sharing in distributed computer systems is investigated. Fundamental issues that need to be resolved in order to implement a load sharing scheme in a distributed system are identified and possible solutions suggested. A load sharing scheme has been designed and implemented on an existing Unix United system. The performance of this load sharing scheme is then measured for different types of programs. It is demonstrated that a load sharing scheme can be implemented on the Unix United systems using the existing mechanisms provided by the Newcastle Connection, and without making any significant changes to the existing software. It is concluded that under some circumstances a substantial improvement in the system performance can be obtained by the load sharing scheme.

The effect of heavy load carriage on pulmonary function at rest and on breathing pattern and lung volumes during graded exercise was studied. Fifteen males completed treadmill tests to measure VO2peak with and without a 25-kg pack. Subsequently, each subject completed short periods of treadmill walking in loaded and unloaded conditions at intensities equivalent to 55, 65, 75 and 85% of VO2peak. At rest, in the loaded condition, forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) both were reduced by 3% with no change in FEV1/FVC. During exercise with the pack, tidal volume (VT) and end-inspiratory lung volume (EILV) were reduced by 14 and 5%, respectively, while ventilation (VE) was maintained by a 9% increase in breathing frequency (Bf). Rating of perceived exertion (RPE) was always higher during the loaded trial, despite identical oxygen consumption (VO2) and heart rate (HR) responses. During graded exercise under heavy load up to 85% of VO2peak, breathing pattern is altered to maintain VE while respiratory mechanics were not altered.
