W. E. B. Du Bois on Brown v. Board of Education

The 1960s have been described as the civil rights decade in American history. Few scholar-activists have been identified as strongly with the legal, social, economic, and political changes culminating in the 1960s as has African American historian, sociologist, psychologist W. E. B. Du Bois. Inexplicably, in 2003, the 100-year anniversary of Du Bois\u27 classic, The Souls of Black Folk (1903), came and went with little fanfare within or outside of academia. However, in 2004, the 50-year anniversary of the initial U. S. Supreme Court decision in Brown v. Board of Education (1954) presents an opportunity for ethnic studies in general, and Black studies in particular, to acknowledge the intellectual and political contributions of Du Bois to the civil rights movement in the United States. In the post-Civil Rights Era, some authors have suggested that Du Bois opposed the initial Brown v. Board of Education (1954) ruling. In contrast, I observe in the present paper that Du Bois (1957) opposed the U. S. Supreme Court\u27s subsequent (1955) ruling that invoked the much-criticized term with all deliberate speed, rather than the initial (1954) ruling that rendered the separate but equal doctrine unconstitutional. Moreover, I contend that Du Bois\u27 own values and attitudes were fully consistent with his position on the (1954, 1955) decisions

Enhanced controlling of the SLS Process during a build

Current commercial Rapid Prototyping (RP) systems like Stereolithography (3D Systems Corporation) and Selective Laser Sintering (DTM Corporation) use galvanometers from General Scanning Inc. (GSI) for the positioning of the laser beam. The GSI scanners are delivered as a ''black box". Operating Consoles which are usually Personal Computers (PC) have very few feedback from the performance of the GSI scanners. Therefore, the PC spends 9000 or more of its time waiting for the GSI scanners to be over with the building of the current layer before sending the information regarding the next layer. Also, very little process control can be performed during the scanning of a layer using the GSI scanners. This kind of setup prevents any dynamic controlling of the process that could prevent building errors like burning, warping etc. At Clemson University, our team has developed both hardware and software components that allows a dynamic control of the building process. New features like scanning one vector with laser power as a function of position and/or time are now possible. Both hardware and software issues will be presented.Mechanical Engineerin

Comparison of two-dimensional and three-dimensional droplet trajectory calculations in the vicinity of finite wings

Computational predictions of ice accretion on flying aircraft most commonly rely on modeling in two dimensions (2D). These 2D methods treat an aircraft geometry either as wing-like with infinite span, or as an axisymmetric body. Recently, fully three dimensional (3D) methods have been introduced that model an aircrafts true 3D shape. Because 3D methods are more computationally expensive than 2D methods, 2D methods continue to be widely used. However, a 3D method allows us to investigate whether it is valid to continue applying 2D methods to a finite wing. The extent of disagreement between LEWICE, a 2D method, and LEWICE3D, a 3D method, in calculating local collection efficiencies at the leading edge of finite wings is investigated in this paper
