Themost commonly used coordinate system in the Hough Transform implementation is (ρ, θ). With nimage points, the ranges of (ρ,θ) can be taken to be ρ: [−M, M ] and θ: [−π, π] where M depends onthe image size. If we restrict θ to be in [0, π] range, then normal parameters for the line will beunique. With this restriction, every line in the x

Two implementations will be discussed: (a) a full IBLA where teams of 4-5 studentsmanipulate the different objects, and (b) a demonstration mode in front of a class of 60 students.IntroductionStudents in higher education strive towards improving their factual knowledge, conceptualunderstanding, problem solving skills, and attitudes. Some argue that conceptual understandingis the most meaningful component among student effort. Educators have worked towardspromoting conceptual understanding in the realm of college physics1 and mathematics, althoughmore work can be implemented in the engineering to realize learning gains. Student success caninclude conceptual understanding and pragmatic outcomes

ofknowledge about the parameter. Gelman et al [8] describe two basic interpretations about theprior distribution: the population of possible parameter values or our state of knowledge aboutthe parameter. In setting up the prior distribution, we choose a class of distributions based onmathematical convenience, which for a Poisson distribution would be the conjugate class ofgamma distributions, Gam(a,b). The predictive distribution, the distribution of the randomvariable Y|X, is negative binomial NB(r,p) with probability of success p=(bns+1)/(bt+bns+1) andr=z+a, where an integer approximation is taken instead of a. We use this distribution to predictthe annual occurrences of tropical storms. Data that record the number per year of tropical cyclones

areevaluated by some form of a final report. In the traditional civil engineering curriculum, undergraduate students take courses withboth lecture and laboratory formats. While the lecture courses provide the opportunity forstudents to absorb new information, the purpose of a laboratory is to expose students to thephysical problems associated with a course and reinforce course content. The traditional type oflaboratory has well-planned experiments, typically containing step-by-step guides leading thestudents through each experiment. Generally in groups of four or five, students in-turn conductthe experiment, regurgitate the results, and prepare a laboratory report, arguably fulfilling ABETstudent outcome (b) “an ability to design and conduct

The model is divides into two main phases (a) hypothesisgeneration and (b) hypothesis evaluation. In phase one the problem-solver acquires informationfrom internal or external sources that can be used to support a representation of the problem.Following this representation, one or more hypothesis are developed that may account for thefault.

Maxwell’s Reciprocity TheoremMaxwell’s reciprocity theorem is a fundamental theorem in solid mechanics and is valid in thelinear elastic region. Referring to figure 6, this theorem states that if a load is applied at point Bon a specimen and the deflection is measured at point C, then the load is moved to point C anddeflection is measured at B the two deflection values will be the same. One of the most importantapplications of this theorem is the symmetry of stiffness matrices in finite elements method. Dueto this symmetry, only almost half of the elements of these matrices need to be
