A new instrument for measuring cloud condensation nuclei (CCN) on board small aircraft is described. Small aircraft are attractive mainly because they are less costly, but they require instruments that are designed for minimum weight, volume, and power con ...
The study of semiconductor interfaces and of solid interfaces in general requires novel instrument capable to investigate the lateral fluctuations of properties on a microscopic scale. We present the first result of a major effort in that framework, whose ...
A novel surveillance system for installed fiber optic cables is presented. It is based on the analysis of the local stimulated Brillouin scattering interaction. The configuration of the instrument rely on the use of a single laser source and the required l ...
During the Limitation of Oxidant Prodn. (LOOP) campaign, different instruments were deployed, providing a complete data set. This will be used to evaluate the model and its ability to reproduce pollution events. Then, the complete data set will be used for ...
The accessory e.g. lamp for illumination of the hand-held instrument (L) and the excitation coils (B1-B3) of the brushless motor (M) are all supplied with current through a rotary connector (F) from a control circuit (C1) within a fixed part of the machine ...
A unique bench-scale heat flux calorimeter is described, which is capable of detecting the low heat signal of an animal cell culture (a max. of 200 mW/l is produced with a batch culture of SF9 insect cells). After the tech. modifications that enhanced the ...
The behavior and performance of four cloud condensation nucleus instruments are theoretically analyzed. They include the static diffusion cloud chamber (SDCC), the Fukuta continuous flow spectrometer (FCNS), the Hudson continuous flow spectrometer (HCNS), ...
Obtaining the listening rates of radio stations in a function of time is an important instrument for determining the impact of publicity. In order to significantly improve the determination of radio listening rates, special watches have been developed whic ...
The geometry of a modern imaging diffractometer is discussed in detail. A method to find all relevant instrument parameters from the control single-crystal measurement data is proposed and the limitations of such a procedure are indicated. Optimization of ...
We present a new type of microinstrument allowing manipulation and mechanical perturbation of individual cells under an optical microscope. These instruments, which we call microplates, are pulled from rectangular glass bars. They have flat tips, typically ...
