Psychological and social effects of noise from aircraft at Tehran International Airport (Iran)

Karami, K. January 1993 (has links)
This thesis is the result of over 2 years research on the ef f ects of aircraf t noise on human health of the residents around Mehrabad Airport (Tehran). other studies in England, Germany, France, Netherlands, Switzerland, Hong Kong, U. S. A., Australia, Nigeria and Canada show a positive correlation between the extent of social and psychological disorders and aircraft noise. Social survey data from questionnaires translated into Farsi highlight relationships -between noise and psychological problems. The Noise and Number Index (NNI) for aircraft noise assessment was derived from noise measurements and correlated with questionnaires. The results were computed by SPSS PC" software. The analysis of questionnaires data demonstrates that aircraft noise exposure causes annoyance and increases tiredness and affects the efficiency and performance of school teachers. Aircraft noise effects are the most severe of noises experienced by residents. It causes psychological and physiological disorders, sleep disturbance and communication difficulties. Noise is a very important factor which needs more attention and further study on its effects on human health and the impact of aircraft noise on different sections of society.

Rural development in North Central Java, Indonesia

Herman Edyanto, C. B. January 1989 (has links)
This study is concerned with the development of coastal rural areas in Northern Central Java-Indonesia. It examines some aspects of rural development processes, including physical and socio-economic factors. The main objectives are 1.to determine the factors significant in coastal rural development; and 2.to specify the kecamatans (sub-districts) most suitable for development purposes based on the evaluation of those factors. Rich in natural resources, coastal rural areas have a high potential for development but this needs to be properly managed for development. The significant factors for this were identified using factor analysis Regional development in Central Java needs to be broken down into more detail programmes, especially if rural development is the object of the study. As in many rural areas in Indonesia, agriculture is the basic predominant activity in the coastal rural area together with fisheries. Therefore, rural development is often concerned with agricultural development. Discussion of the main problems in the specific area is important. This may include consideration of physical, social and economic and cultural problems. Several problems have, therefore, been recognized, namely: the unsatisfactory nature of agriculture development programmes in accelerating rural development, the 5carcity of capital, and the lack of explicit programmes of coastal rural development. Identification of some potential sectors for development, however,can help the planners to overcome such problems. Thus, physical, social and economic sectors should be examined. This leads to the definition of the significant factors for coastal rural development. This study has identified that commercial factors can accelerate development in rural areas; rural development needs adequate investment so that rational allocation measures should be devised. The distribution of development subsidies to rural areas can not be carried out effectively in the indiscriminate way hitherto used by the Government. Therefore the allocation of funds to development should be concentrated on selected kecamatans. Thus to develop these coastal areas an appropriate selection strategy must be evolved. By identifying the critical factors, the kecaniatans best suited for development can be identified based on the appropriate strategy.

The application of advanced computer models to the prediction of sound in enclosed spaces

Howarth, M. J. January 1998 (has links)
Computer modelling of acoustics in enclosures has developed into various forms, none of which have yet demonstrated 100% accuracy. This thesis therefore details a study of room acoustic computer modelling. It highlights weaknesses with existing modelling techniques and describes the development and subsequent verification of an improved modelling technique. The study discovers that for accurate prediction of many common room acoustic parameters diffuse reflections should be accounted for in the modelling of all reflection orders. However, many of the problems encountered in existing techniques are found to be caused by the way these diffuse reflections are modelled. An improved modelling technique, referred to as a 'Hybrid-Markov' method, is proposed and developed that combines a conventional hybrid method with a radiantexchange process to model diffuse reflections. Initial verification of the new modelling technique results in similar overall accuracies to existing modelling techniques but solves many of the specific problems discovered. It therefore provides a flexible and robust framework for the future development of computer prediction of sound in enclosed spaces.

The development of a framework for sustainable waste management policy and strategy for Malaysia

Wan-A-Kadir, W. January 1997 (has links)
This thesis is an analysis and a comparative study of current trends in Waste Management in the UK and Malaysia. The focus is on identifying the policy and strategy framework of Sustainable Waste Management as adopted in the UK and its application for future waste planning and management in Malaysia. The research on the UK waste management practices was done through analyses of official waste policy documents from 35 English counties. Analyses of the 615 policy statements revealed 52 issues and repetitions of terms or terminologies which were labelled in the analyses as 'variables'. These variables were grouped into five categories which were further analysed by; category, county and source of documents. It was discovered that solid waste management in the UK is well institutional ised and legislated. The UK legislative framework provides policy makers with accessible information so as to identify the objectives and to construct necessary measures for sustainable waste management policies. It also established, that the waste management industry needs active participation both from the public and private sectors A case study on Malaysian waste management indicated a total contrast with those discovered in the UK studies. The present Malaysian waste management systems have to be improved with the introduction of specific legislation on waste and the formation of the correct institutions to overlook the Country's waste activities. The research enabled the author to produce a concise set of recommendations for the improved handling of waste in Malaysia.

Modelling and computer simulation of the behaviour of solder paste in stencil printing for surface mount assembly

He, D. January 1998 (has links)
One of the main challenges facing the electronics manufacturing industry in solder paste printing for ultra-fine pitch surface mount and flip-chip assembly is the difficulty in achieving consistent paste deposit volumes from pad-to-pad. At the very small aperture geometries required for ultra-fine pitch and flip chip assembly, flow properties of the paste becomes one of the dominant factors in the printing process. It is widely accepted that over 60% of assembly defects originate from the solder paste printing stage, and hence the urgent need for a better understanding of solder paste rheology, its behaviour during printing, and its impact on defect generation. This understanding is essential for achieving proper control of the printing process. This thesis presents the result of work on the modelling and computer simulation of solder paste behaviour during printing, and consists of three main parts. The first part concerns the modelling of paste behaviour in stencil printing using a vibrating squeegee. The performance of the vibrating squeegee is analysed and process models developed for predicting the ideal printing conditions. In the second part, the random packing of solder powder and the microstructure of solder paste are numerically simulated by applying Monte Carlo method. The effect particle size distributions on the paste microstructure is studied in this part. Based on the simulation results of the second part, the third part concerns the study of the effect of particle size distribution on the paste viscosity and the hydrodynamic interaction between adjacent particles during paste flow. A theoretical enhanced model for predicting the viscosity of dense suspensions such as solder pastes has been developed. This correlates relative viscosity with particle size distribution and with solid volume fraction of dense suspensions. The results of the work have wide applicability: firstly for solder paste manufacturers in optimising paste printing performance at the development stage and for stencil printing equipment manufacturers in specifying the ideal conditions for defect free printing. The simulation algorithm and the viscosity model are also applicable for a wide range of industrial processing applications; in particular metal or ceramic powder compaction, material surface coating, chemical or food material transportation.

The development of the GIST (Grounding Information Systems) methodology : determining situated requirements in information systems analysis

Hughes, J. January 1998 (has links)
This thesis develops a methodology for situated requirements determination in information systems analysis. The thesis challenges convention and adds to the body of knowledge in this area since the methods of the methodology are more usually associated with the social sciences. The role of the systems analyst and the nature of information systems as a distinct discipline form a major part of the thesis and the scope of this investigation includes an exposition of information systems methodologies in general and 'soft' methodologies in particular. A major element of the thesis is the empirical work carried out in which the researcher has undertaken two 'live' systems analysis studies using the methodology which has been developed in action supported by computer software for qualitative data analysis The results from the study are presented in terms of learning and are analysed to help answer the questions relating to the appropriateness of the methodology and the usefulness of the methodology for practising systems analysts. The research methodology used is action case and the appropriateness of this is examined in depth since studies of this type raise a number of questions relating to the validity of this type of research and the role of the researcher. The thesis draws together the different problems and questions that arise in order to produce a coherent, consistent and academically worthy account based upon the literature and empirical findings. In short the thesis addresses the basic issue that motivated its production, namely, how systems analysts faced with organisational complexity really find out what is going on. The outcomes of the research argue for a new role for the systems analyst as postmodern 'bricoleue and tentatively propose the usefulness of social science methods in information systems practice.
