business concepts into a petroleum engineering curriculum.AbstractThe interdisciplinary course, PET 4460 – Petroleum Project Evaluation, offered at MontanaTech, was a direct result of the changing landscape in the petroleum engineering field. Thecourse combined engineering concepts that students learned in other courses withentrepreneurship and other business concepts that entry-level petroleum engineers must possessin order to be successful. Faculty from the Business and Petroleum Engineering departmentsdeveloped the course over a two-year time span with input/feedback from the PetroleumEngineering Department’s industrial advisory board as well as input from upper-levelmanagement from many of the businesses operating in the petroleum arena.

, …wR, each > 1, are the integer weights of input1, input2, … inputR, respectively. Forexample, consider the TH34W2 gate, whose n = 4 inputs are labeled A, B, C, and D, shown inFigure 3. The weight of input A, W(A), is therefore 2. Since the gate’s threshold, m, is 3, thisimplies that in order for the output to be asserted, either inputs B, C, and D must all be asserted,or input A must be asserted along with any other input, B, C, or D. NCL threshold gates aredesigned with hysteresis state-holding capability, such that all asserted inputs must bede-asserted before the output will be de-asserted. Hysteresis ensures a complete transition ofinputs back to NULL before asserting the output associated with the next wavefront of inputdata

No ranking or rating distinction is implied by these letters. Interestingly,two of the 31 programs, 14(F) and 21(D), rated 3.2 and 3.1, respectively, in 2006 did not appearon the list in the three prior years.

Naturally, there are advantages and disadvantages in using any of the above meth-ods. By and large, the method of double integration is the commonly used method in determiningslopes and deflections, as well as statically indeterminate reactions at supports, of beams. With-out using singularity functions, the method of double integration has a disadvantage, because itrequires division of a beam into segments for individual studies, where the division is

This provides an opportunity for the students to practiceconcurrent design and engineering. A typical gearbox design project, such as the one shown inFigure B-1, was assigned to each student. Students were required to perform all necessaryengineering calculations as well as to create each part of the gearbox. Students were thenrequired to create an assembly of the gearbox and to check for interference between parts and tocreate an animation of the gearbox.Since a gearbox consists of many parts, it gave the students an

Given two arbitrary sets, A and B, afunction f is a rule that associates a unique element b=f(a) of B to each element a of A. Instead ofsaying "a function", we may use the term: "mapping f: A 1 B" between A and B, or from A toB. A mapping f: A 1 B is said to be one-to-one if different elements of A are mapped intodifferent elements of B. A mapping f: A 1 B is said to be onto B if for each element b of B thereis an element a of A such that b=f(a). Informally speaking, a mapping f: A 1 B is onto B, if Bcan be covered by the elements of A, using the rule b=f(a). A mapping that is not onto B, is saidto be into B. Finally, a mapping f: A 1 B is called bijective (or

Thus known is a binary relation mappingeach book to those persons recorded in the book, and dates is a ternary relation, whose tuplesconsist of a book, a person known in that book, and that person’s birthday. Or at least that’s whatwe intend: without further constraints there is nothing to ensure the persons known in a book areexactly those whose dates are recorded.To create the needed constraints we add “facts” – predicates that must hold in any legal state ofthe system.
