Engineering andChemical Engineering students at California State University, Long Beach (CSULB). For thestudents, this course is the first introduction to the concept and principal of Fluid Mechanics. Thestudent learning objective is the ability to apply fundamental fluid flow analysis techniques tovarious fluid systems. The students’ performance is assessed based on homework, quizzes,midterms, and a final exam. In the first Midterm, students’ performance has been belowexpectation where students were tested with questions on hydrostatics. However, later in thesemester, students start to have better understanding of the course materials and theirperformances improve. But, because of their poor performance in the first Midterm, students’overall grades

This wasaccomplished by developing resources and teaching strategies that could be employed in avariety of delivery formats (e.g., fully online, online/hybrid, flipped face-to-face, etc.), providingflexibility for local community colleges to leverage according to their individual needs. Thispaper focuses on the iterative development, testing, and refining of the resources for anintroductory Materials Science course with 3-unit lecture and 1-unit laboratory components. Thiscourse is required as part of recently adopted statewide model associate degree curricula fortransfer into Civil, Mechanical, Aerospace, and Manufacturing engineering bachelor’s

! (Equation 6)where Ci is the concentration of specie i, t is time, and ri is the rate of formation of specie i. If thematerial is a reactant, then ri is negative. The overall rate of formation of a specie takes intoaccount all formation and loss reactions in a mechanism. To begin the exercise, students needed to first identify which reactions formed anddestroyed each specie in the overall mechanism. After doing so, a material balance on that speciecould be developed. As an example, ozone (O3) was formed in reaction 2 with rate r2 anddestroyed in reaction 3 with rate r3. Thus, the net rate of O3 formation was r2- r3, and the materialbalance for O3 was determined to be

equallydivided into small intervals. Survey says that memory size used by each interval is very smallcompared to large global memory of GPGPU 9. Thus, a small DRAM is used for executing shortintervals of benchmark. Therefore, the capacity of DRAM is reduced heavily in the hybridtechnology and major portion of memory is replaced with PCM. For the second issue, aneffective algorithm is used to analyze data criticality. The data which are more frequentlyaccessed and accessed earlier are more critical, thus these data are stored in DRAM. A memorycontroller which is employed will update the position and data criticality of the data placed.2.1 Characteristics of PCM Phase change memory uses a Phase changing material called GST.

One of usteaches a variety of ethics courses in the philosophy department. We met two years ago on ateam drawn together to design an ethics module for a course shared across several engineeringmajors. We are now in the process of piloting a full course in engineering ethics that we believewill be adopted by the university as a liberal arts course for engineering majors.

the workshop.Workshop OverviewThe BudgetROV workshop was designed as a 10-week, extracurricular, student-led workshop to give lowerdivision students a chance to obtain hands-on engineering skills. The BudgetROV (a homegrown,student-built, underwater remotely operated vehicle) was selected as the workshop project. An underwaterROV had a high ‘coolness’ factor to attract a wide range of students, and the budget aspect of the BudgetROVdesign (it is about ⅓ the cost of the leading low-cost underwater robot design - the OpenROV​7​) made itaffordable. The workshop was funded by a $500 grant from the Biology department and from a $30 workshopfee per student participant. The grant and fee covered all the materials costs for building three BudgetROVs

The course topicsinclude number representation and theory, basic logic gates, Boolean algebra, HDL concepts,and general “design concepts”.

IntroductionIn Fall 2014, women represented only 11.3% of computer science and computer engineering, and12.2% of aerospace and mechanical engineering students enrolled in these programs at CaliforniaState University Long Beach (CSULB). Figures 1 and 2 show the applications and enrollments byfirst-time freshman (FTF) in the computer engineering and computer science programs from Fall2003 thru Fall 2014. As can be seen from these figures, the one consistent trend is the lowrepresentation by women in applications and in enrollments, signaling a need for increasedrecruitment.As is the case with nearly all of the computing programs in the US, demand for and enrollment inthese majors continues to grow[1, 2].
