Digital Divide: Bridging The Gap Through Ict In Nigerian Libraries, W. O. Nkanu, Henry Itohowo Okon

Library Philosophy and Practice (e-journal)

For Nigerian libraries to fully use available opportunities arising from the use of emerging digital technologies, and contend with the challenges offered by globalization in a rapidly changing information society like ours, the use of ICT must be given top priority. The widening imbalances of access to ICT has resulted in inequitable access to ICTs and other internet-related technologies associated with the provision and use of information services in Nigerian libraries. These imbalances have implication for quality information service delivery in Nigerian libraries. It is in this context that, this paper, discusses the need to bridge the gap through adequate …

A Comparison Of Term Clusters For Tokenized Words Collected From Controlled Vocabularies, User Keyword Searches, And Online Documents, Elaine Maytag Nowick, Daryl Travnicek, Kent M. Eskridge, Stephen Stein

Library Philosophy and Practice (e-journal)

Tokenized word terms were collected from three sources: controlled vocabulary headings, user keyword searches, and html documents all dealing with issues in water quality. Distances were calculated between word pairs using the Jacquard formula. Distances from the three sources were compared using Spearman rank correlations and clusters were calculated on distances transformed for non-normality using the SAS pseudo-centroid method. Word pair distances from controlled vocabularies were more closely correlated to keyword searches than document distances were to users’ keywords. The mean distance of controlled vocabularies was also closer to that of users. Clusters produced from the three sources were most …

Begin The Adventure : How To Break The Light Barrier By A.D. 2079 (3rd Ed.), Florentin Smarandache, Homer B. Tilton

Branch Mathematics and Statistics Faculty and Staff Publications

This edition, the third, has undergone a subtle name change, going from "A.D. 2070" in the title to A.D. 2079 as the timeline is fine-tuned. Because of the almost universal failure to recognize the distinction between physical (reality-based, dynamical) and visual (appearance-based, kinematical) variables, a tremendous volume of mythology arose over the past 100 years centered around Einstein's reality view of the distortions of special relativity. To get a sense of it, we point the reader to Paul J. Nahin's heroic book, Time Machines, 2nd ed.,- to these Tech Notes in particular: TN#6. "A High-Speed Rocket Is a One-Way Time …

An Essay On Cataloging, Daniel Canncasciato

Library Philosophy and Practice (e-journal)

The imminent arrival of Resource Description and Access (RDA), the proposed successor to Anglo-American Cataloging Rules (AACR), makes now an opportune time to clarify a profound misunderstanding regarding the objective of cataloging. The objective has been widely misunderstood to be about the production of bibliographic records, or about the production of bibliographic records and their supporting authority records, or about the production of perfect bibliographic and authority records. This essay offers a more accurate picture of the objective of cataloging, working from Cutter’s early statement of principles as a reference point in re-considering some misperceptions and actions being taken in …

Experimental Study On Thermal Treatment Of Used Printed Wiring Boards (Pwbs), Xiangjun Zuo

Masters Theses

The availability of cheaper and better electronic products as a result of the rapid innovation in technology in past decades has driven the production of e-waste forward. Printed wiring board (PWB) is a component made of one or more layers of insulating material with electrical conductors. The existing processes of recycling PWBs use pyrometallurgical or hydrometallurgical methods, which generate atmospheric pollution. Green recycling has obvious benefits to decrease the amount of PWBs. Green recycling includes two features, 1) little or zero pollution of toxic gases and heavy metals, and 2) efficient (quick and economical) recycling.

The aim of this work …

Maskless Additive Manufacturing Of Micro Structures By Laser Sintering Of Nanoparticles, Vivekram Ramanathan

Masters Theses

"The focus of this study was to investigate an alternate microfabrication process of sintering nanoparticles using a patterned laser light to generate two dimensional (2D) and three dimensional (3D) geometries. With trends of producing electronic and medical devices using cheaper and faster technologies, a new procedure was developed to deposit and bond miniature patterns of silver nanoparticles onto silicon substrates.

The process consists of spraying silver nanoparticles onto the substrate while a patterned or modulated laser beam is focused onto the sprayed nanoparticles. These nanoparticles exposed under the modulated laser light undergo partial melting or sintering and adhere to the …

Adaptive User Interface For Vehicle Swarm Control, Paul Robinette

Masters Theses

"An algorithm to automatically generate behaviors for robotic vehicles has been created and tested in a laboratory setting. This system is designed to be applied in situations where a large number of robotic vehicles must be controlled by a single operator. The system learns what behaviors the operator typically issues and offers these behaviors to the operator in future missions. This algorithm uses the symbolic clustering method Gram-ART to generate these behaviors. Gram-ART has been shown to be successful at clustering such standard symbolic problems as the mushroom dataset and the Unix commands dataset. The algorithm was tested by having …

Differential cross sections were measured for muon transverse momenta pTμ> 1.5 GeV and pseudorapidities -1. 62. 3, as a function of pTμ>, ημ, Q2and Bjorken x. The charm and beauty contributions to the proton structure function F2were also extracted. The results agree with previous measurements based on independent techniques and are well described by QCD …

Efficient Modular Arithmetic Units For Low Power Cryptographic Applications, Rajashekhar Reddy Modugu

Masters Theses

"The demand for high security in energy constrained devices such as mobiles and PDAs is growing rapidly. This leads to the need for efficient design of cryptographic algorithms which offer data integrity, authentication, non-repudiation and confidentiality of the encrypted data and communication channels. The public key cryptography is an ideal choice for data integrity, authentication and non-repudiation whereas the private key cryptography ensures the confidentiality of the data transmitted. The latter has an extremely high encryption speed but it has certain limitations which make it unsuitable for use in certain applications. Numerous public key cryptographic algorithms are available in the …

A search for events containing an isolated electron or muon and missing transverse momentum produced in e±p collisions is performed with the H1 and ZEUS detectors at HERA. The data were taken in the period 1994-2007 and correspond to an integrated luminosity of 0.98 fb-1. The observed event yields are in good overall agreement with the Standard Model prediction, which is dominated by single W production. In the e+p data, at large hadronic transverse momentum PTX < 25GeV, a total of 23 events are observed compared to a prediction of 14.0 ±1.9. The total single W boson production cross section is measured as 1.06 ± 0.16 (stat.) ± 0.07 (sys.) pb, in agreement with an Standard Model (SM) expectation of 1.26 ± 0.19 pb.
