The optical signature in coastal marine environment is a reflection of the complex distribution of optically active marine components. It is essential to understand the relationship between the remote sensing signal and marine constituent material to take advantage of high resolution remote sensing data available from spaceborne and airborne platforms. The objective of this research was to develop a semi-analytical forward model to predict the remote sensing optical signature in coastal waters dominated by non-planktonic material. Laboratory and in situ measurements collected over a5 year period (1998-2003) were used to compile a biogeooptical database for coastal waters. The database is exploited to realise various biogeophysical relationships. A major advancement proposed in the thesis towards the modelling of backscattering probability was the synthesis of knowledge from Mie theory and particulate composition from geochemical analysis. This approach was used to derive particulate backscattering from in situ absorption and attenuation measurements. Results show that this model can produce backscattering values in a realistic way than with a constant value as proposed by Petzold. Absorption and backscattering values derived from ac-9 measurements were used to calculate radiance reflectance and remote sensing reflectance. The biogeophysical relationships developed were incorporated into the forward optics model to successfully simulate the inherent optical property ratio. Further development of the model and applications through inversion were discussed and outlined.Plymouth Marine Laborator

The search for knowledge : from desire to defence : hypothesis for the introduction of a Peirceisch interpretation of the genetic principle of the process of knowing as a fundamental orientation for a future gnoseology

The aim of the thesis is to defend the hypothesis that an anti- Aristotelian interpretation of the genesis of the process of knowing provides an interesting and fruitful means to understand the human never-ending search for knowledge and to answer doubts concerning the reliability of human knowledge of external reality. Such statement requires an explanation

Conspiracy and revolutionary dictatorship in the ideology of Russian Populism, 1861-1881

Revolutionary conspiracies, abortive and successful, have stirred man's mind since the beginnings of governments. Theorizing on the nature of political dictatorship goes back at least to Plato. It is the ideological linking of these two activities—the plot of a "revolutionary" party to overthrow an existing government, and the establishment of a "dictatorship" by that party in the aftermath of the revolution--, within the framework of the Revolutionary Populist movement in Russia in the 1860's and 1870's that constitutes the thesis of this paper. The French Revolution, with its Jacobin Terror (1793-4) and the "Conspiracy of Equals" of Gracchus Babeuf (1796), offers the most convenient starting point for modern historical research into revolutionary dictatorships and secret society activity. It is conclusively established by the writings of Russian revolutionary figures that the revolutionary events in Prance in the 1790’s, 1830's, and 1840’s share priority with the Russian peasant rebellions of Stenka Razin (l670-1) and Emelyan Pugachev (1773-5) in the influence exerted upon the young radicals of nineteenth century Russia.

The technological economics of glass recycling

This thesis examines the technological economics of glass recycling in Britain. Attention was focused on recovery schemes operated within Scotland, comparisons being made with schemes in the rest of Britain and in Europe. An examination was made of general recycling problems and of glass recycling problems in particular. The various systems for glass recycling were reviewed and were put in the context of the waste management system as a whole. A survey was undertaken of Local Authorities operating glass recycling schemes. The aim was to provide a comprehensive data set to enable a consistent assessment of glass recovery schemes to be taken. This emphasised the importance of taking a standard approach to assessing the viability of recovery schemes. This needs to be done in terms of both private and social costs and benefits to provide a full economic assessment of the system. A general computer model has been developed to allow local authorities to check the viability of their on-going operations. As they operate under different conditions this model was split into separate assessment of a Bottle Bank scheme and a trade collection scheme. In addition, an investment appraisal model was developed to cover both situations. These allow managers to assess the viability of their schemes and can be used to highlight key costs. An International review was undertaken to see what lessons may be learned and what actions may be taken by the local authorities, industry, the general public, and by central government
