Abstract Over the years the term technical progress has been given a wide range of meanings and interpretations. Here we shall use the term in two main senses which will subsequently form the subject-matter of the two main sections of this Survey. First we shall use the term to refer to the effects of changes in technology, or more specifically the role of technical progress in the growth process. Secondly, we shall use the term to refer to changes in technology itself, defining technology as useful knowledge pertaining to the art of production. In this context, we shall be concerned with the knowledge-creating activities of research, invention and development, together with the process of absorption of new knowledge into the productive system. These two interpretations of the term technical progress correspond broadly to the division in the economic literature between “macro”-studies which attempt to quantify the rate of technical progress as a determinant of the growth of output, and “micro”-studies which seek to explain the process of technical change—usually in a disaggregated way in firms and industries. In some places our Survey will overlap with the recent theoretical survey of growth by Hahn and Matthews [112], but in the main it is its complement, except that to emulate its thoroughness and masterly exposition would be a technological feat in itself! Our instructions were to make this Survey Anglo-centric. But for reasons that economists will appreciate it has come inevitably to stride the Atlantic with by far the larger foot in North America.

WE must now introduce technical progress into the picture. At present we continue to assume that corresponding to each state of technical knowledge there is only one possible method of production for each type of commodity and of equipment (a spectrum of technical possibilities, entailing different ratios of labour to capital in a given phase of knowledge will be discussed in the next chapter).1

After more than twenty years, discussions on the truthlikeness of scientific theories, initiated in the seventies, have not, in my opinion, arrived at final conclusions; but they have contributed positively to improving our comprehension of scientific progress. Niiniluoto s (1984) contribution is especially useful to define what we may call the kernel of the current standard view of scientific progress. This can be summarized in the following thesis:

During the past quartile (two month period) most attention has been concentrated on the problem of definition critical temperature at which ''wet'' corrosion first became operable. It has been shown that, in principle, ''wet'' corrosion processes can not be ignored for Yucca Mountain, even for initial times, when the temperature of the surface of containers is well above the boiling temperature of water for the prevailing conditions. This is because the surfaces are covered by highly hydrophilic oxides (e.g. Fe{sub 2}O{sub 3}, NiO, Cr{sub 2}O{sub 3}) that will hydrate to the form of corresponding hydroxides, which are proton conductors, at least when in the ''wet'' condition. Because proton conduction and the presence of ''bound'' water are all that are required for the external environment to support metallic corrosion in either its general or localized form. Thus, the temperature of dehydration of the hydroxide, e.g. M(OH){sub 2} {yields} MO + H{sub 2}O(g), is a better criterion for the upper temperature limit for ''wet'' corrosion than is the boiling temperature of ''bulk'' water. During this first task, we have reviewed the existing thermodynamic data base for the dehydration of metal hydroxides and analytical expressions have been developed that allow the upper temperature limit to be estimated.

An ignition source was constructed that is capable of producing a pulsed corona discharge for the purpose of igniting mixtures in a test chamber. The corona generator can also be used as the ignition source for one cylinder on a test engine. The first tests were performed in a cylindrical shaped chamber to study the characteristics of the corona and analyze various electrode geometries. Next a test chamber was constructed that closely represented the dimensions of the combustion chamber of the test engine at USC. Combustion tests were performed in this chamber and various electrode diameters and geometries were tested. Higher peak pressures and faster pressure rise times were realized consistently in all test chambers versus standard spark plug ignition. A test engine was purchased for the project that has two spark plug ports per cylinder to The data acquisition and control system hardware for the USC engine lab was updated with new equipment. New software was also developed to perform the engine control and data acquisition functions including cylinder pressure monitoring. A ceramic corona electrode has been designed that fits in the new test engine and is capable of withstanding the pressures and temperatures encountered inside the combustion chamber. The corona ignition system was tested on the engine and an increase in both peak pressure and IMEP were seen in the initial test. There are issues that must be addressed before on-engine testing can continue such as EMF interference from the corona generator and electrical insulation on portions of the piston and cylinder head to prevent arcing. The EMF issue can be solved with proper shielding and grounding and various ceramic coatings are being researched for electrical insulation.
