The current paper focuses in more detail on the heat transfer component of this project. The educational goals of the heat transfer tutorials include the following: 1) to develop thermal FE tutorials that are easily accessible and require minimal instructor effort in order to integrate them into a required mechanical engineering undergraduate heat transfer course, 2) to provide undergraduate engineering students with a basic understanding of FE theory as applied to thermal analyses, 3) to provide undergraduate engineering students with an ability to apply commercial FE

Children’s toys and the so called “executive toys” or novelties have also beenemployed as demonstration tools7-10. Properly selected toys offer at least threeadvantages: (1) they are relatively inexpensive and readily available for immediate use;(2) there is a good chance that students are familiar with them from their ownexperiences; and (3) they exhibit a wide variety of scientific concepts. In addition to theirutility for classroom demonstrations, toys can be used for other educational purposessuch as informal science education and inspiring ideas for student projects.The literature on toys in education is

currently available in civil engineering can cover all the aspects of it. At thebeginning of the project, two different approaches were compared: 1. developing only one new class to include all aspects of waste tire applications 2. add teaching modules to different levels and related civil engineering classesThe second method was chosen because it is more flexible and can reach more students. It alsogives students more opportunity to be exposed to waste tire educational materials.Therefore, it was proposed to develop waste tire application teaching modules for a variety ofcivil engineering courses from freshman level to senior level. Each module contained one ormore lectures. Figure 1 illustrates the courses that training modules were developed

Why online teaching? Theanswers will be attempted on this paper.Online in EE-The previous discussion was created to set up the scenario of what we have donesince the Fall semester of 2006. In this section we will indicate the implementation of an onlinegraduate level course in Electrical Engineering. This course has been taught for several years inthe face-to face (classroom) mode and it has had the usual outcomes of such way of teaching.However, online teaching created a challenge of great magnitude at the logistical andinstructional, and

Figure 1. All blocks have identical outer dimensions. Students are allowed to designgeometric features on two planes of the block. The block designs form mating patterns withthose designed and fabricated by other students. The instructor specifies the assembly order ofthe blocks. During the design phase, students must complete their designs and pass them to otherstudents in a scheduled time frame. Students have to interact with each other frequently todiscuss the design details and negotiate necessary modifications. Students must completelyunderstand each others’ drawings and check for possible mismatches both in dimension andshape. Once each design is completed, the drawing will be arbitrarily given to another student forfabrication.The blocks

These are experiences that both increase knowledge and increase credibility. An interestingexample of such an experience in programming might be competing in (and perhaps winning) aninterschool programming competition. The most difficult quadrant for teaching and learning is the lower right. In that quadrant theexperience has high external credibility and has a low potential for increasing knowledge.

Extensive written reports and formal oralpresentations are required in each course.Prior to the curricular changes discussed in this paper, the Aircraft Detail Design course involvedminimal wind tunnel testing and the limited involvement of an HU/COM instructor who servedin strictly an advisory role. The change in the course content addressed perceived weaknessesthrough: 1) additional verification of analysis via test and 2) an increased emphasis oncommunication skills.The first curricular change required students

For K-12, we are talking about first steps toward this goal, which certainly involves enhanced exposure to a broad range of fundamental scientific content as well as conveying the excitement of scientific research. Beyond this, however, is the need to lay a foundation in such overarching subjects as the varied to good scientific process, systematic analysis, and problem-solving, complemented by development of good communication skills and the ability to work well in collaborative groups.

SSL Client AuthenticationIn SSL v3/TLS, the less well known, and frequently unused communal authentication of bothclient and server is applicable. Not only is there the SSL Server certificate as previouslydiscussed, but a client browser certificate is used as well. Thus, those who desire to access theserver must be pre-enrolled and be possessors of a client browser digital certificate. Thecertificate exchange is done via x.509 certificates, and public key cryptography is used to startthe connection. Two to four seconds is required to establish the secure connection. Onceauthentication is made, the channel is secured with symmetric key cryptography methods andhashes, typically RC4 or 3DES for symmetric key and MD5 or SHA-1 for the hash
