The goal of the College is to produce graduates having strongtechnology and communication skills as well as a good understanding of business practices andwork ethics.The academic program model is driven by two sets of learning outcomes at both the college andUniversity levels. All IS courses are developed to address College and University level learningoutcomes. Master course syllabi are developed to show the course contributions to variouslearning outcomes. During

Richard Lazarus (ascited in Priesmeyer et al.15) confirmed many of the basic emotions in this list through hisown research and provided much discussion about the interaction of emotions thatdirectly contributed to the interpretation and analysis of emotional dynamics in theEmogram system. An important step in the development of Emogram was the creation ofprecise photographs depicting varying degrees of the eleven basic emotions.The Emogram system provides measures of each of the emotions by combining responsesto low, medium, and extreme expressions of each. It also computes an overall EmotionalQuality (E-Quality) score that reflects the overall emotional

IntroductionInformation and computer technology programs are plagued by several major challenges. First,computing technologies are evolving at a rapid pace, making it difficult for schools to maintainup-to-date technologies in physical labs due to budget constraints. Second, lab exercisesdeveloped by faculty have short life span and need to be updated to reflect new

The course also covers roughly 80% of the core andelective learning outcomes of the Information Technology computing curriculum proposed in2005 by the Association for Computing Machinery2.2. Boundaries and FlowsThese two concepts were chosen as the organizing concepts or “themes” of the course.A boundary separates two elements of a system and may thereby provide a degree of protection.As stated in the US government’s Information Assurance Technical Framework (the IATF),“Information assets exist in physical and logical locations, and boundaries exist between theselocations”8. This statement reflects the fact that students must consider a system’s physical aswell as logical elements

Instructors are also encouraged to act as cognitive coaches who can nurture an environment that can support open inquiry. (Barrows, 2000). It is important that the aims and objectives of problem-based learning are reflected in every aspect of the learning environment created. Problem-based curriculum should document accomplishments at the upper levels of Bloom's Taxonomy Triangle. (Boud & Feletti, 1991). Scholars in the area of cognitive science and educational psychology have identified four features that clearly separate a problem-based curriculum from a traditional, topic-based curriculum. (Nickerson, et. al. 1985). In this

(“Authentic” here is used in the instructional design sense,IE a learning experience that closely reflects the professional practice the students will enter intoupon graduation.) Students pursuing authentic experiences in this manner show great enthusiasmfor learning both because the degree of control they perceive that they have over the process andbecause they sense that they are engaged in projects that are important to a real customer, IE theyare aware of and motivated by the authenticity of

This approach is valuable, but can lead to a sense of isolation ifthe participants cannot easily reflect with each other on their new experience. Other programsassign small groups of students to labs in order to decrease the potential for isolation. Thisresearch reports on the structure of a highly-successful REU site with a relatively rareconfiguration: 15 participants are co-located in a single lab but grouped in teams of three, andeach team works on an existing research project.

The outcomes reflected the fact that thereis some sort of interference that will occur depending on the different sources of interference.As the Bluetooth and IEEE 802.11 continue to grow and gain popularity, it becomes apparentthat more studies should be conducted to avoid the interference issue in the 2.4 GHz band. Toachieve this, IEEE 802.15.2 Task Group has been formed specifically to consider proposalsfor mechanisms to improve the level of coexistence between Bluetooth and IEEE 802.11devices and to come up with recommended practices derived from these.Although different authors discussed the effect of Bluetooth on IEEE802.11b and vice versa,none of them have

higher level.The Cognitive TheoryIt is widely known that programming, even at a simple level, is a difficult activity to learn. Why isthis so? Are novice difficulties really inherent in programming or are they related to the nature ofthe programming tools currently given to novices? Bonar and Soloway11 presented evidence thatcurrent programming languages do not accurately reflect the cognitive strategies used by noviceprogrammers. Instead, Bonar and Soloway11 have found that novice programmers possessknowledge and experience with step-by-step specifications in natural language. This knowledgeand experience gives them powerful intuitions for using a programming language. Programminglanguages, however, are not designed to appeal to these

This fact has been reflected, in part, by a surgein laptop sales over the recent years. Vice president of Gartner’s worldwide computingplatforms, Charles Smulders, states that “Consumers are flocking to notebooks because of lowerprices, better performance, and an increased appreciation for wireless technologies.”5 Theincreased appreciation here stems from the transparently bridging technologies.

The operating systems of interest to the project wereWindows XP and Linux, so these were both investigated for suitability.When attempting to install Windows XP on a USB drive, problems immediately arose, when theinstaller halted before loading the OS.

The earliest MEA implementations had student teams write a single solution to aproblem in the form of a memo to the client and receive feedback from their TA. For researchpurposes, a simple static online submission form, a static feedback form, and a single databasetable were quickly developed. Over time, research revealed that students need multiple feedback,revision, and reflection points to address misconceptions and achieve high quality solutions. As aresult, the toolset has been expanded, patched, and re-patched multiple developers to increaseboth the functionality and the security of the system. Because the class is so large and

The hybrid collocated and non-collocated controlscheme is then realized with an adaptive JBC position controller and an inverse end-point-modelvibration controller. A recursive least squares algorithm is utilized to obtain an inverse model ofthe plant in parametric form. The problem of controller instability arising from the non-minimum phase characteristics exhibited in the plant model is resolved by reflecting the non-invertible zeros into the stability region. The performances of both schemes are investigatedwithin a flexible manipulator simulation facility. An alternative to the parametric approach described
