Cloud Computing: Strategies For Cloud Computing Adoption, Faith J. Shimba Dec 2010

Cloud Computing: Strategies For Cloud Computing Adoption, Faith J. Shimba

Faith Joel Shimba

The advent of cloud computing in recent years has sparked an interest from different IT stakeholders. This is a result of the new economic model for the IT department that cloud computing promises. The model promises to remove the need for heavy investment for limited IT resources towards renting IT resources and paying based on usage. Although, the adoption of cloud computing promises various benefits to organizations, a successful adoption requires an understanding of different dynamics and expertise in diverse domains. Currently there are inadequate guidelines for adoption and this book proposes a roadmap for cloud computing adoption called ROCCA ...


Bridging The Gap Between The Industrial Environment And The Classroom Via Project-Based Learning, Michael W. Martin Oct 2010

Bridging The Gap Between The Industrial Environment And The Classroom Via Project-Based Learning, Michael W. Martin

Michael W Martin

Recent engineering education research has concluded that most engineering curricula do not promote attainment of many characteristics desired in practicing engineers. Methods to attain these characteristics include both project-based learning (PBL) and simulation of workplace situations in the educational environment. The presenter will outline the use of both PBL and workplace simulation through the implementation of a semester-long project in a senior-level Data Acquisition course taught out of the Department of Engineering Technology at Northern Michigan University. A typical undergraduate experimental analysis or data acquisition course will review topics including; sensoring, hardware requirements, testing techniques, computer integration, software use, and ...


The Impact Of Multiple Computing And Digital Arts Degrees On Undergraduate Recruitment, Amber Settle, Liz Friedman, Mary Jo Davidson Oct 2010

The Impact Of Multiple Computing And Digital Arts Degrees On Undergraduate Recruitment, Amber Settle, Liz Friedman, Mary Jo Davidson

Amber Settle

In this paper, we describe a two-year study of the factors influencing freshman and first-year transfer student enrollment at the College of Computing and Digital Media (CDM) at DePaul University. Our results show that the reputation of the institution, the particular degree programs at DePaul CDM, and to a lesser degree the diversity of degree programs available, were all positive factors for application and enrollment at DePaul. Factors that were not of primary importance included parental influence, the fact that DePaul is a liberal arts institution, and recommendations from relatives and friends.

Absolute Ground-State Nitrogen Atom Density In A N2/Ch4 Late Afterglow: Talif Experiments And Modelling Studies, Et. Es-Sebbar, M.-C. Gazeau, Y. Benilan, A. Jolly, C D. Pintassilgo

Dr. Et-touhami Es-sebbar

Following a first study on a late afterglow in flowing pure nitrogen post discharge, we report new two-photon absorption laser-induced fluorescence (TALIF) measurements of the absolute ground-state atomic nitrogen density N(4S) and investigate the influence of methane introduced downstream from the discharge by varying the CH4 mixing ratio from 0% up to 50%. The N (4S) maximum density is about 2.2 × 1015 cm−3 in pure N2 for a residence time of 22 ms and does not change significantly for methane mixing ratio up to ~15%, while above, a drastic decrease is observed. The influence of the residence ...

Talif Investigation And Modelling Of The Absolute N(4s) Density In A N2-Ch4 Late Afterglow, C.D. Pintassilgo, Et. Es-Sebbar, Y. Benilan, M-C. Gazeau, A. Jolly Jul 2010

Talif Investigation And Modelling Of The Absolute N(4s) Density In A N2-Ch4 Late Afterglow, C.D. Pintassilgo, Et. Es-Sebbar, Y. Benilan, M-C. Gazeau, A. Jolly

Dr. Et-touhami Es-sebbar

The purpose of the present work is the experimental and numerical study of the absolute ground-state nitrogen atoms density N(4S) in the late afterglow of a pure N2 flowing microwave discharge in which different amounts of CH4 have been injected at 25 cm downstream from the nitrogen discharge. The absolute N(4S) concentrations have been measured using Two-photon Absorption Laser-Induced Fluorescence (TALIF), while a detailed kinetic model has been developed to simulate both the discharge and the post-discharge regions. Theoretical predictions are then compared to experimental measurements.

Combined Experimental And Theoretical Studies On Methane Photolysis At 121.6 Nm And 248 Nm- Implications On A Program Of Laboratory Simulations Of Titan’S Atmosphere, C. Romanzin, E. Arzoumanian, Et. Es-Sebbar, A. Jolly, S. Perrier, M.-C. Gazeau, Y. Bénilan

Dr. Et-touhami Es-sebbar

Methane is, together with N2, the main precursor of Titan’s atmospheric chemistry. In our laboratory, we are currently developing a program of laboratory simulations of Titan’s atmosphere, where methane is intended to be dissociated by multiphotonic photolysis at 248 nm. A preliminary study has shown that multiphotonic absorption of methane at 248 nm is efficient and leads to the production of hydrocarbons such as C2H2 (Romanzin et al., 2008). Yet, at this wavelength, little is known about the branching ratios of the hydrocarbon radicals (CH3, CH2 and CH) and their following photochemistry. This paper thus aims at investigating ...


Temperature-Dependent Photoabsorption Cross-Section Of Cyano-Diacetylene In The Vacuum Uv, N. Fray, Y. Bénilan, M.-C. Gazeau, A. Jolly, M. Schwell, E. Arzoumanian, Et. Es-Sebbar, T. Ferradaz, J.- C. Guillemin Jun 2010

Temperature-Dependent Photoabsorption Cross-Section Of Cyano-Diacetylene In The Vacuum Uv, N. Fray, Y. Bénilan, M.-C. Gazeau, A. Jolly, M. Schwell, E. Arzoumanian, Et. Es-Sebbar, T. Ferradaz, J.- C. Guillemin

Dr. Et-touhami Es-sebbar

Using synchrotron radiation as a tunable VUV light source, we have measured, for the first time, the absolute photoabsorption cross sections of HC5N with a spectral resolution of 0.05 nm in the region between 80 and 205 nm from 233 to 298 K. The measured cross sections are used to predict the HC5N photodestruction rate in the solar system and to model a transmission spectrum in Titan's atmosphere. Comparing the latter with that acquired by the Ultraviolet Imaging Spectrograph on board the Cassini spacecraft, we have determined an upper limit of 2.7 × 10−5 on the HC5N ...

Proceedings Of The 2009 Nrc Federal Facilities Council/James Madison University Symposium On Protecting Large Facility Complexes;, George H. Baker, Cheryl E. Wilkins

George H Baker

Large, complex facilities pose unique protection challenges involving multidisciplinary expertise and collaboration among government, academia, and the private sector. The symposium served as a forum for sharing experiences in dealing with large facility catastrophic events and risk management. The symposium was organized based on the value of interaction among different people representing diverse disciplines. In many instances, such interactions lead to solutions that would not have been developed within disciplinary stovepipes. The venue was divided into three panels addressing physical security, cyber security, and real facility case studies. We were also privileged to have three keynote speakers including Dr. Charles ...

Learning Styles And Entrance Requirements For Online Master’S Programs, Stan Lightner, Mark Doggett, Vesta Whisler Dec 2009

Learning Styles And Entrance Requirements For Online Master’S Programs, Stan Lightner, Mark Doggett, Vesta Whisler

Mark Doggett

As more online graduate programs are created and traditional programs shift to an online format, the need to identify and understand skill sets necessary for students’ success becomes more apparent. Typically, graduate programs rely on entrance requirements such as the GRE, undergraduate GPA, and a writing sample to evaluate an applicant’s potential success. Is it reasonable to expect that other entrance requirements might be needed for student success in online graduate degree programs?

Research comparing learning and personality styles of online learners exists; however, application of this information as part of the admissions process for online graduate programs is ...

Better To Be Frustrated Than Bored: The Incidence, Persistence, And Impact Of Learners' Cognitive-Affective States During Interactions With Three Different Computer-Based Learning Environments, Ryan Baker, Ma.Mercedes Rodrigo, Sidney D'Mello, Arthur Graesser

Ryan S.J.d. Baker

We study the incidence (rate of occurrence), persistence (rate of reoccurrence immediately after occurrence), and impact (effect on behavior) of students’ cognitive-affective states during their use of three different computer-based learning environments. Students’ cognitive-affective states are studied using different populations (Philippines, USA), different methods (quantitative field observation, self-report), and different types of learning environments (dialogue tutor, problemsolving game, and problem-solving based Intelligent Tutoring System). By varying the studies along these multiple factors, we can have greater confidence that findings which generalize across studies are robust. The incidence, persistence, and impact of boredom, frustration, confusion, engaged concentration, delight, and surprise were ...

Controlled Language - Does My Company Need It?, Uwe Muegge Dec 2009

Controlled Language - Does My Company Need It?, Uwe Muegge

Uwe Muegge

A controlled language is a natural language, as opposed to an artificial or constructed language. Natural languages such as English or German are languages that are used by humans for general communication. A controlled language differs from the general language in two significant ways: 1. The grammar rules of a controlled language are typically more restrictive than those of the general language. 2. The vocabulary of a controlled language typically contains only a fraction of the words that are permissible in the general language.

Mining And Civilization, An Illustrated History, Fathi Habashi Dec 2009

Mining And Civilization, An Illustrated History, Fathi Habashi

Fathi Habashi

Mining and Civilization has been conceived to compliment the author's two books History of Metallurgy and Readings in Historical Metallurgy and to fill a gap in the literature. It is difficult to study the history of metallurgy without studying the history of mining at the same time. Each time the author visits ancient ruins or examines an ancient stone statue he recalls the work of miners who brought the material from a quarry so that the sculptor can create a work of art. History of mining, quarrying, and stone carving is history of civilization.
