An inexpensive blackbody model

A blackbody is a fundamental concept in thermography. A perfect model of blackbody is characterized by emissivity =1 which is difficult to be obtained. There are black body simulators which are being used for calibration of infrared devices. Commercial solutions of blackbody simulators are based on mathematical models of cavity or surface blackbodies and their emissivity is closer to unity e.g....

An EMMA and EPG study on token-to-token variability

The potential role of physical correlates of articulatory variability in vowel production was studied by means of EMMA and EPG. In accordance with Perkell & Nelson (1985), the hypothesis to be tested is that the amount and shape of token-totoken variability is influenced by the amount of palatal contact in such a way that high vowels exhibit different variability patterns than the other vowels....

An Inexpensive Light Stage Dome

This article describes a process for constructing a real-world 1 m-diameter icosahedral dome frame with equipment mounting points at the vertices. Such frames, called Light Stage domes, are important tools for computer graphics and vision measurements and relighting applications. Typical domes have 2 m diameter and are constructed from bolted steel parts. The new half-size dome is inexpensive, ...

An Inexpensive Suture Practice Board

OBJECTIVE We provide a design for an effective suture practice board for surgical instruction that is both easily assembled and repaired. METHODS This model's design is achieved through inexpensive materials that do not compromise adequate simulation through repetitive use. We used a wooden board, synthetic microfiber cloth, and metal plates and screws to create the suture board. Two pieces o...
