Answer to histogram

Abstract:

If during a certain time interval a mobile operator takes data of delivery times of each message sent through the network. Can the data be represented using a histogram?Answer: Yes. Suppose there are 30 000 messages sent through the network in the time interval concerned. Class-intervals can be constructed to represent the frequency with which the messages fall within different classes. Thus a histogram will be suitable for representing the data.

Art in Engineering - Moving Art

Abstract:

Students learn how forces are used in the creation of art. They come to understand that it is not just bridge and airplane designers who are concerned about how forces interact with objects, but artists as well. As "paper engineers," students create their own mobiles and pop-up books, and identify and use the forces (air currents, gravity, hand movement) acting upon them.

Creating eBooks for distance education - Case study

Abstract:

Download the supporting PDF file for this episode http://bit.ly/f1v3iH from the Learning to Teach Online project website.

This case study examines the use of eBooks and eReaders as an extension of the usual Blackboard Learning Management System (LMS). This initiative was undertaken as part of the DUCKLING research project (Delivering University Curricula: Knowledge, Learning and Innovation Gains) conducted by the Beyond Distance Research Alliance at the University of Leicester in the UK.

While the context of this study involves distance students, using electronic books can have applications in any discipline where students are required to undertake a significant amount of reading. This case study discusses some advantages of using eBooks, and outlines the process involved in creating and uploading them to an eReader device.

Hurricane Ivan Rainfall Structure seen by TRMM on September 16, 2004

Abstract:

NASAs TRMM spacecraft is used by meteorologists to understand Hurricane Ivan. TRMM views Ivan on September 16, 2004, just as the storms most intense rains and winds makes landfall. The cloud cover is taken by TRMMs Visible and Infrared Scanner (VIRS). The rain structure is taken by TRMMs Tropical Microwave Imager (TMI). It looks underneath of the storms clouds to reveal the underlying rain structure. Blue represents areas with at least 0.25 inches of rain per hour. Green shows at least 0.5 inches of rain per hour. Yellow is at least 1.0 inches of rain and red is at least 2.0 inches of rain per hour.

MERLOT

Abstract:

Multimedia Educational Resource for Learning and Online Teaching. The MIC07 conference theme Jazzing IT up with MERLOT recognizes the collaborative efforts within disciplines and the education community around the World to enhance teaching and learning through the use of Instructional Technology. Conference attendees span all disciplines and the continuum from novice to expert in the development and use of online resources. The conference is designed to foster learning, innovation and practice in the use of information, instruction, and communications technologies in higher education. It is the venue for educators, administrators, and technologists who have interests and expertise in technology-enabled teaching and learning and who recognize the need to remain current in this rapidly advancing field of educational practice and theory.

MobilED blog

Abstract:

MobilED initiative is designing learning environments that are meaningfully enhanced with mobile technologies and services.

We design scenarios and guidelines of how mobile technologies could be used for teaching, learning and empowerment of students within and outside the school context.

We design concepts, prototypes and platforms that will facilitate and support the scenarios and guidelines developed.

We test, evaluate and disseminate the scenarios, guidelines, concepts, prototypes and platforms in real contexts with real people.

Mobile Autonomous Systems Laboratory, January (IAP) 2005

Abstract:

MASLab (Mobile Autonomous System Laboratory) is a robotics contest. The contest takes place during MIT's Independent Activities Period and participants earn 6 units of P/F credit and 6 Engineering Design Points. Teams of three to four students have less than a month to build and program sophisticated robots which must explore an unknown playing field and perform a series of tasks. MASLab provides a significantly more difficult robotics problem than many other university-level robotics contests. Although students know the general size, shape, and color of the floors and walls, the students do not know the exact layout of the playing field. In addition, MASLab robots are completely autonomous, or in other words, the robots operate, calculate, and plan without human intervention. Finally, MASLab is one of the few robotics contests in the country to use a vision based robotics problem.

Mobile Forces

Abstract:

The application of engineering principles is explored in the creation of mobiles. As students create their own mobiles, they take into consideration the forces of gravity and convection air currents. They learn how an understanding of balancing forces is important in both art and engineering design.
