The CT density of the same pulmonary nodule can vary significantly between scanners or with the same scanner because several independent factors besides partial volume averaging can affect its determination. Hence a single CT number cannot be used to distinguish calcified from noncalcified nodules, ruling out direct extrapolation of quantitative data(More)
We are designing a number of programming projects which utilize input/output devices, such as joysticks or a homebrewed board we call a MIPPET (Module for Input/Output Programming Projects Enhancing Teaching). These projects have been used or will be used in the closed labs of our CS1 course (taught in C++). The goal of these projects is to enhance student(More)
Eight different conducting polymer films formed from pyrrole and N-substituted pyrrole derivatives were characterized by cyclic voltammetry, X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy. In particular, the XPS of poly[N-butylpyrrole], poly[N-(2-carboxyethyl)pyrrole], poly[N-(6-hydroxyhexyl)pyrrole] and(More)
The approach to program visualization in computer science instruction discussed here has two components: the graphic display of algorithms and the graphic display of their execution. Both types of display are based on the same hierarchical representation of an algorithm (in terms of Scandura FLOWforms, an enhancement and generalization of Nassi-Shneiderman(More)
The attachment of blood platelets to the surface of bare and protein-coated thickness-shear mode acoustic wave devices operating in a flow-through configuration has been studied. Platelets in washed from bind to the gold electrodes of such sensors, but the resulting frequency shifts are far less than predicted by the conventional mass-based model of device(More)
