Interactive Breakout Sessions



Two interactive breakout sessions will take place during NATEG DAYS'12; one in the morning of the first day and a second one in the morning of the second day. These sessions are meant to be very interactive and hands-on, with one or two instructors moderating the session and with participation from a small group of students (~25-30/group). Students will be asked to register for one session per day during their registration for the event on the website. A given breakout session can be offered more than once to different groups of students.


Nanotechnology-enabled water purification system

Session Organizers :

Steve Carpenter
Zoubeida Ounais

Summary


The global water crisis is a contemporary economic, political, cultural, and social condition that inhibits adequate access to affordable and efficient water purification systems and is responsible for 3.5 million deaths each year due to disease. In this session participants will work collaboratively in small groups to propose an affordable and efficient point of use water filter produced through the combination of nano-sized silver and local clay. Informed by actual case studies, this session provides participants an opportunity apply science, engineering, and design knowledge to build on existing possibilities and challenges for rendering pathogen contaminated water potable

Participants will:
- Assess case studies of nano-sized silver for rendering pathogens inert
- Examine properties of nanotechnology and local clay
- Propose innovative means to combine nano-silver and local clay to produce an affordable and effective means for rendering pathogen contaminated water potable



Actuators for microsystems applications

Session Organizer :

Ridha Ben Mrad

Summary


The session will start with an overview of microelectromechanical systems (MEMS) technology and its potential. A large number of MEMS sensors are already available in the market. In many cases, MEMS sensors have almost completely replaced traditional sensors over the last 10 years. MEMS actuators are, on the other hand, still developing and a number of significant technical challenges need to be overcome before these MEMS actuators can replace traditional actuators.
A number of problems related to MEMS actuation will then be discussed. The first problem will be focused on enhancing the stroke of surface micromachined electrostatic actuators and the applications of such actuators in a number of fields such as for the development of micromirror-based head up display system and positioning of lenses for next generation cell phone camera systems. The second problem will be focused on actuation at the microscale for the purpose of automation of biomedical laboratory protocols such DNA synthesis, testing for disease such as testing for biomarkers for HIV, Tuberculosis, Hepatitis and others, specifically on digital microfluidic chips where micro droplets of fluids are manipulated in an open area. The fabrication of these chips and issues related to their performance will be discussed.


Products Dissection and Recombination

Session Organizers :

Scarlett Miller
Richard Schuhmann

Summary


Product dissection is often utilized during the design process as a way to systematically uncover opportunities for re-design, provide competitive benchmarks and gain knowledge and insight about a particular product. Since even the most novel ideas are often developed through the combination or reconfiguration of previous ideas and concepts, this session will focus on teaching participants to decipher the physical principles of simple devices, and examine issues of design, manufacturing and materials selection in new product development in order to generate new innovative ideas. The experience is an example of problem-based learning which emphasizes visualization and collaboration.

Participants will:
- Dissect and define the operational physics of common devices
- Reinvent these devices using simple materials
- Recombine these devices into a new product

Satellite dish antennas: How do you watch channels on NileSat and Hotbird? What are some of the problems with existing satellite dish antennas? What are some possible solutions? How do we go about inventing a solution? Green cellular telephony: Is cellular telephony a green technology? What is the carbon footprint of cellular communication? How can we reduce it?


Basic Technical Requirements for Effective Machine Design

Session Organizer :

Lazhar Mazlout

Summary


In order to design machines efficiently, the designer needs to have a good working knowledge of basic machine components and an innovative spirit in putting these individual components into a working system. It is impossible to cover all these components in one session or even in many. However, the most basic and important ones will be covered. Also, we will cover the most common materials used and the main reasons one would select one material over another. Finally, the important aspect of tolerances and fabrication will be presented.


A Window into the wireless industry in the U.S.

Session Organizer :

Mohamed Bourouha

Summary


In this session we will have an overview of wireless networks, trace its evolution, and understand some of its key elements. We will also open a window to one of the most advanced wireless carriers in the US, understand how it operates and what are some of its top challenges

Students will:
* Get an introduction to how such an industry operates in the US
* Have a chance to observe how live Network tools and reports help track network performance and improve coverage foot print
* What are some of the challenges of new generation wireless networks, and what are some of the innovative ways to address them
* Students will also be able to ask questions and interact with the speaker and get a deeper understanding of US corporate work environment and some of the key skills future engineers should have.


Tubular Expansion Technology in Oilfields Down Hole Applications

Session Organizer :

Abdennour Seibi

Summary


Downhole tubular expansion has been developed by Shell in early 90s and became a common technique of well construction and rehabilitation in order to decrease cost of drilling and completion as well as enabling safe exploration of deeper hydrocarbon reserves. Over 99,100 m of solid pipe have been expanded downhole since the first installation on November 25, 1999. The first commercial installation was the in situ expansion of 305 m of 7-5/8 inch OD (194 mm), electric resistance seam welded, "80" grade ("550 MPa") carbon steel pipe in a well in the Gulf of Mexico.
This technology produces extensive plastic radial deformation up to 25% of the pipe diameter; therefore, affecting the pipe ovality and wall thickness. Participants will be divided in small groups to develop the steps involved in the design process of the expansion tools and sensing devices.

Participants will:
* develop customer requirements and design requirements,
* come up with some design alternatives, and
* conduct a detailed design of a selected expansion device.

This session is only offered on July 16th morning.
