Engineering Design The development of computer-aided part modeling software can be traced to the early 1960’s. These early CAD packageswere two dimensional systems, designed to fulfill only the role of electronic drawing board. During this same period, efforts in the areaof NC machining by companies in the aeronautical and automotive industries lead to the mathematical work in the area of computer-modeling of sculptured surfaces. Finally, computerization of engineering analysis began with the development of finite element analysis(FEA) software. This software relied upon geometric modeling techniques for both pre-processing (development of the modelgeometry) and post-processing (display of the results)5.During the early 1970’s, efforts were

Proceedings During this period, several formats for pre-freshman summer orientation were utilized and severalsuggestions for developing a group identity were followed. At one point a “Support Program for BlackFreshman in Tech” was instituted in conjunction with a black engineering faculty member and five blackgraduate students. The intent was to provide a “big brother/big sister” arrangement and focused tutoring. Taking 1970 as the reference year, the subsequent growth and a later downward trend of minorityenrollments are shown in Table 1 and Fig. 1. The first half of the decade of the 70’s saw the freshman enrollment rise to 69 or 6.4% of the classand the number of graduates four years later to 50 or 5.4% of the class. The overall

with some informal cooperative learning exercises. In my next class period, I started out by dividing the students into groups of three or four and askingthem to take five minutes to write down everything they could remember about our previous lecture. At theend of the allotted time, I called on each group to tell me one thing from their list and proceeded to write it onthe board. By going from group to group in this manner, and with a little prodding from me, we managed toreconstruct the essential information from my previous lecture in about 15 minutes. The dialogue usually wentsomething like ME: All right, group number one, what do you remember about the last lecture? STUDENTS: We remember an ‘S’-shaped curve

Voiced speech is predominant in spoken vowels. On the other hand, unvoiced speech can be seen as arandom, white noise produced by air turbulence in the vocal tract. Examples of unvoiced speech include thesound of words starting with letters such as “s”, “th”, “f’, “t”, “p”, etc., basically the sound of all consonants.

slightly better for students using EDIC S than for those using the-equivalent text. (The two principalpenalties to EDICS were that the tests excluded anything that involved animations or video, because these couldnot be treated in the text; and that the tests were based on a small part of EDICS and an equivalent smallnumber of pages of text. Computer systems have a large advantage over text when dealing with a large mass ofinformatio~ as is typical of design problems). EDICS could be considered to have won the battle but, becauseof technological limitations, to have lost the war.

where they react and then aredesorbed. In some cases the properties of surface facilitate the reaction. Such a system is calledheterogeneous catalysis. One such reaction is the combination of oxygen and hydrogen to formwater. This mixture when ignited by a spark or flame will ignite and explode with violence.Normally, no reaction occurs at room temperature. However the presence of a platinum substratewill serve to catalyze the reaction. In the mid-1 820’s, Dobereiner passed hydrogen through aplatinum gauze. The hydrogen catalyzed by the platinum combines with oxygen from the air. Themixture ignites and then begins to burn. Dobereiner developed a very successful commercialproduct - fire lighter - based on this principle. The instrument was

Technology transfer refers to all the activities leading to the adoption, adapta-tion, or demonstration of a new product or procedure by any group of users. Due to political considerations, itis sometimes diflicult to transfer technology to some parts of the world where relations are not friendly with theUnited States. In general, the United States willingly shares certain technologies with other countries. Mostoften the problem is a lack of resources in other countries to understand a technology and implement it.
