This pedagogical tool for asynchronous teaching and learninghas recently been employed in the online engineering program in the State University of NewYork (SUNY) at Stony Brook.Index Terms – Assessment, Asynchronous learning, Online courses, Video Podcast.1. IntroductionMillennial students grow up with exposure to technology and are quite adapted to live withtechnologies, including their products and benefits. As a result, they are also pushing, andperhaps challenging, faculty to expand their technical horizons. Both students and faculty todayhave available to them many technologies that did not exist a decade ago. Such technologies canprovide

. 1. Support mechanisms such as the existence of a water board, a partnership with a local NGO, and strong personal relationships with community members can contribute greatly to sustaining a small-scale project. 2. Engagement in hands-on projects in a real-world environment helps students to better understand the engineer's role in society and transition to a successful professional career. 3. Student reflections show how these experiences have enhanced their education beyond the traditional classroom experience.AcknowledgmentsThe authors would like to thank the Tufts University School of Engineering, the Tufts Institute for GlobalLeadership, and the Jonathan M.

minimum specifications and are required to apply thelearning they had into the design of a NMOS-input Operational Amplifier that can be implemented in an N-well CMOS process. The specifications include open loop gain, gain-bandwidth product, phase margin,common-mode rejection range, slew rate and output swing on a specified load including capacitive loading.The requirements are (1) to create a Mathematica file of their design calculations, (2) verify the design withappropriate SPICE simulations, (3) create a layout design that passes all design rules, and (4) write a reportand do a Powerpoint presentation to the class at the end. Projects that pass the design specifications andlayout rules can be sent out to be fabricated. However, typical turn

cache-timing attack that was capable enoughto break Rijndael’s seal that encapsulates the encryption key. In this paper, we propose Dynamic CacheFlushing (DCF) algorithm which shows a set of pragmatic software measures that would make Rijndaelimpregnable to cache timing attack. The improved Rijndael algorithm viz, DCF Algorithm provides bettersecurity by encrypting key at constant time. 1. Introduction Rijndael is a block cipher adopted as an encryption standard by the U.S. government. It has beenanalyzed extensively and is now used widely worldwide as was the case with its predecessor, the DataEncryption Standard (DES). Rijndael, the AES standard is currently used in various fields. Due to itsimpressive efficiency, it’s being used in

Newton’s Laws.1 Cadets analyzed the motion of the front cart of theroller coaster as the cart executes a loop. Project tasks included the determination of the location and themagnitudes of the maximum and minimum speeds, location and magnitude of the maximum totalacceleration, as well as relating this maximum total acceleration to “g-forces.” After determining that thefront cart feels the greatest total acceleration at the 2 o’clock position, cadets are asked to analyze theforces on the cart at this location. 1a 1b 12 9 3 6 E (Exit) I (Inlet) Figure 1a

analogsignal. Digital control is the simpler of the two control methods since only an on/offsignal need to be received by the device. For a solenoid valve a 5 volt signal might turnthe valve on while a zero volt signal would turn the valve off. An electrical heater isanother example of a device that can work with either digital or analog control. Theheater can either be on or off, digital control, or we can vary the current to the heater,proportional control. To send these signal we simply need an electrical switch. A simpleelectrical switch available commercially is called solid state relays. Other electricalswitches are available.The students also master the following skill list:1.

Robots and Mobile Robots An intelligent robot is different to the traditional mobile robot. The traditional mobile robot uses apowerful microcontroller to control the movement, with the help of sensing devices it normally is able tomake a tactic decision but could not do any sophisticate thinking since the limitation of the computationpower provided by microcontroller. The left of Fig.1 shows the Stamp Bobot which is equipped withStamp microcontroller and light, touch and other sensors.

rationalconsideration of all influencing factors and a careful examination of all impacting parameters are the onlyway toward reaching decisions that are satisfactory to all concerned parties. It is usually the responsibilityof the design engineer to comply with required codes and regulations, to harmonize conflictingviewpoints, and to find a common ground that is acceptable to all. 1 Student Competition, ASEE Zone 1 Conference, West Point, March 28-29, 2008MethodologyA course entitled Artistic Engineering was structured to address a research methodology that examinesthe effect of engineering and non-engineering factors on the design of some of the most sophisticatedstructures ever built

follows: assume that a multiple choice question with four possible answers has correct answer “D” andis worth one point. The traditional technique requires students to select one right answer, so if a studentanswers “D”, the student receives a 1 or a 0 for all other answers. Conversely, a strictly proper scoringrule requires the student assign probabilities that each possible answer is correct, say A=0.1, B=0.2,C=0.05, D=0.65. The student’s score depends on the scoring rule applied. Under the logarithmic scoringrule, the student would receive ln(0.65) points or -0.43. The scores are obviously bounded by (-∞, 0].Usually, the instructor rank orders students’ scores and then assigns final grades. This situation can beextremely punitive for students

This change was made for all eight engineering programs such that all engineeringstudents would experience a common curriculum during the first year. Many benefits have resulted fromthis change over the past decade including the following highlights: • Retention of engineering students from the freshman year to the sophomore year increased from ~60% to ~72% (see figure

content means making tough choices about what to remove in order tomake room. This paper proposes a viable method for weaving a green environmentality into a standardundergraduate reinforced concrete design course without sacrificing course content. The United States Green Building Council has established an industry standard in Green BuildingRating Systems with their Leadership in Energy and Environmental Design (LEED) certification. TheLEED certification process involves earning credits for environmentally friendly construction processesand materials and the use of efficient building systems. The certification has several tiers (gold, silver,etc.) for different levels credit.1 One way LEED credit can be earned is through use of recycled
