the importance of attendance on student success has been gained.The research project is far from completion. The opportunity to examine the impacts ofattendance on individual students as they progress through their academic years towardgraduation can be examined. There is still much to investigate leading to new discoveries andfindings uncovering facts that can be utilized to guide and advise students on ways to besuccessful during their college experience. Exactly where the new direction of the study will gois unknown. One future area of research could be to focus on specific reasons for poorattendance that correlate with a drop off in grades.Bibliography 1. Armstrong, J.

Department at OregonInstitute of Technology.Development of the FEA course at OITFinite Element Analysis (FEA) is a numerical method for solving engineering problems bysimulating real-life-operating situations on computers. Finite element analysis proceduresevolved gradually from the work of many people in the fields of engineering, physics, andapplied mathematics. The use of finite element analysis (FEA) become widespread in the 1960’sand 70’s, initially in the automotive and the aerospace industries. During that period of time,expensive mainframe computers were required to run the finite element analysis, and finiteelement models typically required days to create. The task of interpreting results were also verydifficult. Customized software were

In thisapplication, an AISI 1040 steel with 90,000 psi in tensile strength was selected. AssumingFs =1.5, the allowable working bending stress σ b is found as 60,000 psi.

to 1950’s [1] researchers started to explore this technology. Simplyspeaking, computer vision deals with the technology that mimics the capabilitiesof a human (normal) vision system. Naturally, a normal human being is equippedwith sensors for five different sensing capabilities (vision, smell, taste, touch, andhear). These capabilities are controlled by the central nervous system (brain)allowing a human being to demonstrate intelligent behavior. By default, thevision system of a human being is three dimensional and it uses two eyes thatwork as sensors (detectors) to capture images. Earlier computer vision systemused only one camera along with the associated computational platform andsoftware and therefore, it dealt largely with two

Magnet field analysis may also beused for finding torque, force, power losses, and induced voltage, which are the primaryparameters of electrical machine performance study.This paper presents the magnet field analysis of a cylindrical permanent magnet linear alternator.This alternator has four permanent magnet rings mounted on a plunger (shaft), which oscillateslinearly when the machine is working. The magnetic polarities (N pole or S pole) of the rings arein radial direction and the polarities alternate from one ring to the next on each side of theplunger. Two of the magnet rings are on each end of the plunger and a magnetic loop is formedby the permanent magnet rings, plunger, stator
