The radiations from 60-day Sb lN have been studied by several investigators. H ales and Jordan [2] used a 1800 spectrometer to study the beta spectrum of Sb124. Tbey report the presence of two components with maximum cnergies at 0.74 ± O.03 and 2.45 ± 0.07 million electron volts (NIev) . ~1iller and Omtiss [3], u ing a thin magnetic len spectrometer , also ob erved a complex beta specLrum, but ...

Finding structure in multiple streams of datais an important problem. Consider thestreams of data flowing from a robot’s sen-sors, the monitors in an intensive care unit,or periodic measurements of various indica-tors of the health of the economy. Thereis clearly utility in determining how currentand past values in those streams are relatedto future values. W...

An Artif ic ial Visual System ( AVS ) has been deve l oped to simplify three dimensiona l microscope image~ f o r presentation and man ipul ation l n an interactive compu ter g raphics s ystem.

A recombination algorithm processes the filter ou tputs to detect ob j...

Opacity Pulse Propagation Measuremen ts in Humans: Atraumatic Screening for Carotid Arterial Occlusion • Opacity pulse propagation times to areas of facial skin supplied by internal carotid (medial supraorbital area) and external carotid arteries (lateral supraorbital areas, cheeks, etc.) were carried out in 27 patients with cerebrovascular symptoms, 16 of whom had normal four-vessel angiograph...

Background: Cold crystalloid cardioplegic solution is used for cardiac arrest and myocardial protection during CABG intermittently. There is no defined safety interval time for cardioplegia infusion. Measuremen of the metabolite release from myocardial cells in coronary sinus implicateis accurate protective effect and safety interval of cardioplegia. There is no study that surveys the metabolit...

The measuremen t of the spectral emlSSlVl ty of heated substances may be accomplished by comparing the energy emitted by the substance under study 'with that emitted by a standard substance for radiation at various wavelengths. For such a standard one usually uses a blackbody, that is, a hollow body provided with a hole for viewing the radia tion inside. The inside surface of the blackbody must...

31 Recently, Aharonov, Anandan and Vaidman [1,2] showed t hat the wavefunction of a si ngle quantum system could be determined from t he resu lts of a series of "protective measurements" performed on the system. In t he protective measurement scheme, a-prio ri knowledge of the wavefundion of the system is used in order to measure t his system and protect its wavefunction from changing at the sa...

THISARTICLE IDENTIFIES A NUMBER OF RESEARCH TOPICS related broadly to outcomes assessment in a networked environment and discusses issues affecting these research topics. It also proposes a framework to relate traditional evaluation components and terminology to the networked environment and identifies a number of factors in the networked environment that affect outcomes and other assessment me...
