Natural Radiative Lifetimes of the 5p6s^(1)P_(1) , 5p6s^(3)P_(1,2), and 5p5d^(3)D_(1,2,3) Levels of the Sn I Spectrum by Zero Field Level Crossing Spectroscopy

Natural radiative lifetimes of some excited levels belonging to the 5 p 6 s and 5 p 5 d configurations have been measured by the Hanle method. Some of the levels could be optically excited only from the metastable 3 P 1 and 3 P 2 levels of the 5 p 2 ground configuration. These comparatively low-lying levels were sufficiently populated at the temperature necessary to produce a Sn atomic beam. The f

Recursive estimation of the continuous-time process parameters

The problem of continuous-time process parameter identification is considered. Filtered input-output process signals are used to create a linear differential equation governed by the same continuous-time process parameters. The estimation scheme is implemented by sampling the filtered signals and using a recursive least squares algorithm (RLS). The choice of filter leads to different parameter con

Institutions and Social Mobilization: The Chinese Education Movement in Malaysia

This paper studies the persistency of minority social movement in pushing its agenda over a long period of time. Focus on institution as the main independent variable for social mobilization, this thesis argues that structural institutions such as rules and constitutions shaped the foundation framework for collaboration among the movement community, and legitimated the selection of leaders. Howeve

Market transformation for energy efficiency - a case study of the introduction and diffusion of heat pumps in Sweden and Switzerland

Since 1970s the development and introduction of heat pumps have been supported as a strategy to improve energy efficiency in Sweden and Switzerland. Several policy instruments have been applied, such as R&D, subsidies/electricity price incentives, labelling and quality test centres. The justification of introducing heat pumps as an energy-efficient end use technology was, in general, to decrea

Definite marking and referential status in Greek, Swedish and Polish

This article presents an analysis of definiteness from a cognitive and typological approach. The claim is that definiteness is a property based on referential grounds, and that this property goes beyond the language specific variations. First, some theories of the concept of definiteness are presented, together with a brief typological overview. Then follows the analysis of three languages: Greek
