Hybrid technique, radiation

Hybrid techniques such as corrugating the cone with secondary suction and coating can achieve successful decoupling at higher frequencies, thereby minimizing node flexure. Nonetheless, some degree of node flexure is evident in most direct radiators. Extreme examples are shown in Fig. 3.59 (Berwick, 1994, 49) that illustrate the deleterious effects of such uniform piston breakup. 

Numerical models for Soil-Structure Interaction effects are based on Finite Element Methods (FEM), Boundary Element Methods (BEM) or hybrid techniques. Although FEM are well estabHshed procedures, e.g., Bathe (1996) and Cook et al. (2002), they are not free of shortcomings especially when modeling of infinite domains is in order. In such cases special developments are required to satisfy the radiation condition... 

The U.S. - Australia Symposium on Radiation Effects on Polymeric Materials contained research presentations on fundamental radiation chemistry and physics as well as on technological applications of polymer irradiation. This paper represents a hybrid contribution of these two areas, examining a field of extensive technological importance. Spin casting of radiation sensitive polymer resists for microelectronic fabrication was studied using photophysical techniques that are sensitive to the fundamental radiation response in the ultraviolet range. 

In situ hybridization may be defined as the detection of nucleic acids in situ in cells, tissues, chromosomes, and isolated cell organelles. The technique was described in 1969 by two separate groups who demonstrated repetitive riboso-mal sequences in nuclei of Xenopus oocytes using radiolabeled probes (1,2). Refinements in recombinant DNA technology and the development of nonisotopic probe labeling and detection (3) obviate the need for radiation protection and disposal facilities, and have converted nonisotopic in situ hybridization (NISH) from a purely research technique to one that can be used in routine laboratory testing. 

In order to perform the experiments presented in this Chapter, we implemented the miniMIPS hardened with the novel hybrid HETA technique and the software-based techniques Variables and Inverted Branches on both flash-based and SRAM-based FPGAs. We visited three facilities, used two types of energetio particles, and performed tests for SEE and TID. In the following, each radiation experiment and its results are diseussed in detail. 

Raman Microscope Raman microscopy [41, 42] is a hybrid of optical microscopy and Raman spectroscopy and, in consequence, has all the concomitant advantages of both techniques. The main purpose of the microscope is to excite, collect, and couple the Raman radiation very efficiently from the sample to the Raman spectrometer, and to provide a means for sample positioning and viewing at high magnification. The Raman microscope can analyze the vibrational frequency shift at different points of a surface, so as to resolve areas with different chemical composition, which is referred to as chemical imaging.
