Interface Capacitance

The limitations of conventional a.c. capacitance measuring techniques, for such measurements as MIS interface capacitance and measurements of large value electrolytics, has lead to a demand for new methods of capacitance measuring. This article reviews two new approaches which are presently being employed – the quadrature P.S.D. technique and time encoded ballistic techniques.

Do So

Biomedical endeavours can be divided into three major categories: research, education, and testing. Within the context of each of these categories, activities involving whole animals have made major contributions and will continue to do so in the future. However, with technological developments in the areas of biotechnology and computers, new methods are already reducing the use of whole animals in certain areas. This article discusses the general issues of alternatives and then focuses on the development of new approaches to toxicity testing.

Wheel Loading

In the first part a static investigation is made of the total elasticity of the track on soft sub-soil and loose ballast, and for rock and consolidated bedding. The oscillating mass of the permanent way will differ in behaviour, depending on construction, rail profile, sleeper spacing, etc. The damping and the phase shift can be determined by modern measuring techniques and a few limit values are given. In the second part the dynamic behaviour of the track is investigated for velocities up to 200 km/h. New methods of measuring the wheel loading on the rail are briefly described. Elements of permanent way calculation, based on new methods of computation, are briefly considered. The role of the lateral elasticity of the rail is shown in the third part, theoretically and according to measurements.

Increasing of demand in the energy sphere and also unprecedented proliferation of environmental pollutants in the air has pushed human toward the using of renewable energy sources such as photovoltaic systems. Unfortunately, despite all the efforts made, in the field of photovoltaic systems, still the usability of this clean and renewable source is skeptical in the world. This paper examines some basic problems of photovoltaic systems and discusses a few new approaches to reduce some problems of photovoltaic systems. The proposed approaches have capabilities and difficulties which are investigated in this study.

The Comparative Study

This chapter summarizes new approaches to the study of traditional dialects, in particular in Britain and the United States, and discusses how new methods, new results, and new topics of investigation may inform and enrich the study of World Englishes, too. Of particular importance may be the acknowledgement of widespread variability in the ‘homeland’ that is increasingly also historically attested and sociolinguistically described, the study of morphosyntactic variation as an area of language that seems to remain quite stable under settlement conditions, and the comparative study of present-day variability that indicates the breadth (and limits) of variability. In return, results from the comparative study of World Englishes also have the potential to enrich modern dialectology and sociolinguistics.

Rapid changes in time and space in the micro-relief of an ablating glacier surface and radiation-induced melt within the uppermost ice layer, termed the “weathering crust”, seriously affect the accuracy of the short-term ablation measurements. The various measuring techniques commonly used (stakes, ablatometers, ablatographs) and some new methods (measurement of discharge from a small supra-glacial drainage basin, and mass loss directly measured on core samples) are critically reviewed and assessed in the light of these phenomena. The implications for studies of heat and mass balance are discussed.It appears that the direct measurement of mass flux is the most accurate means of assessing short-terni ablation rates. The errors in short-term ablation measurements by any method are largely compensatory and consequently do not influence long-period mass-balance estimates.
