follows: 1. Convert the new bridge B to its canonical variant C(B). 2. Compute H(C(B)), the hash string for the canonical variant. 3. Search the database for all bridges Mi with stored hash string equal to H(C(B)). 4. If no such bridge is found, go to 6. 5. Otherwise convert each bridge Mi to its canonical variant C(Mi) and check whether C(B) = C(Mi) for any i. If so, a duplicate has been found, otherwise continue. 6. There is no duplicate. Store the pair B and H(C(B)) in the database.Since a standard database engine can look up a hash string very rapidly, and canonical variantsand hash strings are also quick to compute, this algorithm successfully met the performancerequirement.A second challenge was determining the unofficial

RAM, 8 analog inputs, 4 PWM outputs,and up to four 8-bit ports for general I/O. It is easily interfaced to a serial port, however to addUSB connectivity an FTDI USB-Serial bridge8 was used. Under Windows and Linux this ICappears as a serial port. The processor (thumb) board includes a power LED and four LEDs onport B for simple diagnostics. A reset switch is used to restart the processor. The design of theboard allows it to be directly inserted into a USB port, eliminating the need for any extra cables.The board was also configured with two diodes to allow it to draw power from the USB port (5V,0.5A) or from an external power source. In this case there was a voltage drop, but the ATMega32works with a supply voltage under 4V. The board uses a

present project therefore is an effort todevelop a much more comprehensive Compressible Fluid Flow Solver (CFFS) intended forclassroom and educational use.Objectives of the paperIn the Department of Mechanical Engineering at Lamar University, compressible flow course isan elective course typically offered in the spring semester of each year. It is a three-credit hourclass with three 1-hour lectures per week. This paper describes the development of a web-basesolver for compressible flows using Java programming language. The main goal of the solver isto provide students with a software tool that can be used in the compressible flow course. Themain objectives of the project are (a) To design and develop a compressible flow solver (b) To test and

To address these issues, there are a number of initiatives that have been made to provideexperimentation facilities over the Internet 3, 4, 5, 6, 7, 8, 9. None of these facilities are designed todeliver a laboratory course that is a part of a regular educational program. In addition to these,all these suffer from one or more of the three main drawbacks. These are: a) complexity indevelopment; b) higher cost; and c) single server can provide access to only one experiment at apoint in time. Although the Internet-based laboratory facilities have a number of potentialbenefits, these drawbacks hinder the process of gaining their popularity. The paper will describe the

The second sample question examined understanding the principles of light sensor operationand, from physics, how light intensity from a point source falls off as a function of distance.This behavior of light is important because most fire-fighting robots depend on light sensors todetect a flame, and many use reflectance sensors to determine distance to arena walls and otherobstacles.Q2: The light intensity from the source O measured in points A and B equalsIA = 4 W/m2, IB = 9 W/m2.

In another example, a student is concerned with her/his performance, andwants to determine whether she/he is keeping up with the rest of the class.The development, analysis, and iterative refinement of these scenarios provided unique insights into theneeds of students viewing their performance data. We discussed these scenarios with other students,faculty, and as a semester long project in a graduate seminar course at Virginia Tech.The insights gained helped us identify several qualities of performance that students are interested in atdifferent times. These include: a) Performance relative to other students b) Perfect scores/missed scores c) Adequacy
