Mobile Telephone Detection, Benjamin Moss, Todd Hubing

Opportunities for Undergraduate Research Experience Program (OURE)

A common threat to military personnel in Iraq is the use of unconventional warfare. Improvised explosive devices (IEDs) are crudely fashioned using explosives wired to consumer radio electronics. Garage door openers, two-way radios, and mobile telephones are a small sampling of the devices used in IEDs. The diverse nature of these devices makes it difficult to preemptively detect an IED using traditional means. Various methods of mobile phone detection are investigated, taking into account the type of phone and the available detection equipment. Specifically, a first-generation mobile phone is detected using an oscilloscope and MATLAB.

The Online Language Learning Environment: New Roles For The Humanist, James S. Noblitt

Russian Language Journal

Thomas Edison played an important role in improving the technologies needed for the telephone. He was said to have been excited about the educational potential of the new instrument and speculated that it would soon be found in every classroom.

Well, he was right about the educational potential of information and communication technology, but he was wrong about the form the new technology would take.

This chapter raises questions concerning the role humanists will play in determining the development and implementation of information and communication technologies for educational purposes.

Perspectives On Curriculum Construction At The Postsecondary Level: Contexts, Approaches, Principles, Heidi Byrnes

Russian Language Journal

A curriculum is an attempt, wrote Stenhouse three decades ago (1975, 4), to communicate the essential principles and features of an educational proposal in such a form that it is open to critical scrutiny and capable of effective translation into practice.

If one applies that notion of curriculum to the foreign language field in general, and to second- or foreign-language learning in U.S. colleges and universities in particular, one is immediately confronted with a dilemma: how can we speak of a foreign-language curriculum at the college level when a principled approach that is open to scrutiny and that builds on …

Investigations Of The Kinetics Of Liquid Droplets On Soil Substrates Using A Novel Approach: Contact Ratio, Abdelhafiz “Moh’D Adnan” Herbawi

Theses

In view of young’s equation, in which the contact angle “ϑ” and the liquid surface tension γ_lv are the only measurable parameters, the contact angle has been widely conceived as a thermodynamic quantity. Accordingly “ϑ” has been the main focus of most theoretical and experimental investigations. The rate of change in the contact angle has been commonly used as the relevant parameter of spreading dynamics in spite of difficulties associated with contact angle measurements that are well recognized in the literature. Considering that the velocity of the contact line is the pertinent quantity for spreading, it is therefore reasonable …

"An Investigation Into The Potential Of Immobilized Nitrifies In Wastewater Treatment", Ahmed S. Embaby

Theses

Removal of ammonia from wastewater is one of the problematic issues in wastewater treatment because nitrifies are very slow growing and can be washed out from activated sludge processes. There is a need to use higher advanced techniques to retain biomass. Among these techniques is cell immobilization in appropriate reactor environments. Cell immobilization technology can be approached by various methods, including cell entrapment or biofilms. However, these immobilization techniques are often accompanied by challenges in terms of biomass activity preservation and recovery following the immobilization treatment, reduction of nutrients mass transfer rates, adequate performance under shock situations and preservation of …
