Technical Processing Of University Library: A Theoretical Study, Rajib Kalita

Library Philosophy and Practice (e-journal)

Technical services operations comprise of ordering, claiming and receipt of materials, cataloging and classification of materials; and serials control. Beside these, other technical services operations contain circulation, documents, foreign language and special collections, and bibliographic instruction in technical services areas. This leads me to believe that the distinction between technical services and public or reader services in individual libraries is based on custom and tradition arising out of incidental circumstances, rather than on fundamental principle. In this article, I tried to provide some basic aspect regarding technical processing which help in maintaining the library bitterly. In this article, I include …

Faster First-Order Methods For Stochastic Non-Convex Optimization On Riemannian Manifolds, Pan Zhou, Xiao-Tong Yuan, Jiashi Feng

Research Collection School Of Computing and Information Systems

SPIDER (Stochastic Path Integrated Differential EstimatoR) is an efficient gradient estimation technique developed for non-convex stochastic optimization. Although having been shown to attain nearly optimal computational complexity bounds, the SPIDERtype methods are limited to linear metric spaces. In this paper, we introduce the Riemannian SPIDER (R-SPIDER) method as a novel nonlinear-metric extension of SPIDER for efficient non-convex optimization on Riemannian manifolds. We prove that for finitesum problems with n components, R-SPIDER converges to an -accuracy stationary point within O min n + √ n 2 , 1 3 stochastic gradient evaluations, which is sharper in magnitude than the prior Riemannian …

Revocable Attribute-Based Encryption With Decryption Key Exposure Resistance And Ciphertext Delegation, Shengmin Xu, Guomin Yang, Yi Mu

Research Collection School Of Computing and Information Systems

Attribute-based encryption (ABE) enables fine-grained access control over encrypted data. A practical and popular approach for handing revocation in ABE is to use the indirect revocation mechanism, in which a key generation centre (KGC) periodically broadcasts key update information for all data users over a public channel. Unfortunately, existing RABE schemes are vulnerable to decryption key exposure attack which has been well studied in the identity-based setting. In this paper, we introduce a new notion for RABE called re-randomizable piecewise key generation by allowing a data user to re-randmomize the combined secret key and the key update to obtain the …

The Effects Of Supervisory Style And Supervisory Working Alliance On Supervisee Disclosure In Supervision: A Moderated Mediation Analysis, Chi Li

Counseling & Human Services Theses & Dissertations

Supervisee disclosure in supervision is considered as a critical factor influencing the effectiveness of supervision (Spence et al., 2014). Despite previous researchers’ efforts to understand the concept (e.g., Knox, 2015; Yourman & Farber, 1996), a consensus over the definition for what is considered as supervisee disclosure is missing, posing threats to the construct validity of existing supervisee disclosure measures (e.g., Gunn & Pistole, 2012; Mehr, Ladany, & Caskie; 2015). Therefore, based on a summative definition (e.g., Ladany et al., 1996; Hess et al., 2008; Walsh, Gillespie, Greer & Eanes, 2003), Li and Kemer (under review) developed and provided initial validation …

Cryptic Herbivorous Invertebrates Restructure The Composition Of Degraded Coral Reef Communities In The Florida Keys, Florida, Usa, Angelo Jason Spadaro

Biological Sciences Theses & Dissertations

Coral reefs have been on a trajectory of decline for nearly a century due to a variety of factors that have contributed to the shift in these communities away from dominance by reef-building corals, with commensurate changes on community composition and function. Florida’s reefs are a compelling example of a degraded system that has undergone a phase shift, and thus offered an excellent model system for my study of the effects of grazing by cryptic herbivores on community composition and their potential restoration value. I had four major objectives: (1) determine the suitability of Maguimithrax spinosissimus for manipulating grazing intensity …

Effects Of Prison Program Participation On Recidivism Outcomes, Jordan Jakobs

Sociology & Criminal Justice Theses & Dissertations

Although the relationship between prison programs and recidivism has been extensively researched, few studies have examined the role of commitment as a part of social bond theory and its relationship to prison programs and recidivism. Based on a nationwide sample of 9,890 prisoners, the concept of commitment is used as a paradigm to understand whether completion of prison programs increases bonds of commitment to conventional activities thereby reducing the rate of recidivism. The analyses indicate that commitment improves recidivism outcomes for offenders who completed alcohol and drug treatment programs but not for those in vocational and educational programs. These results …

Must Stay Woke: Black Celebrity Voices Of Dissent In The Post Post-Racial Era, Lily Kunda

Institute for the Humanities Theses

In today’s racially charged climate there is an expectation that black celebrities cry out #BlackLivesMatter, get on the field to #TakeAKnee and be #UnapologeticallyBlack whenever they are in the spotlight. This climate transcends what was once seen as a post-racial America— a time where the media portrayed race as no longer being an issue— and encourages black celebrities to address racism. Prior research on black celebrities by Sarah J. Jackson, Ellis Cashmore, bell hooks, James Baldwin and others acknowledges the historical burden placed on black celebrities to publicly discuss racism and represent blackness in order to challenge dominant narratives. Today, …

The Women Of Explosive Ordnance Disposal: Cyborg, Techno-Bodies, Situated Knowledge, And Vibrant Materiality In Military Cultures, April Michelle Cobos

English Theses & Dissertations

Women’s service in the U.S. Explosive Ordnance Disposal (EOD) community began in the 1970s amidst policy changes that opened more active duty roles to women while maintaining restrictions on their access to combat. However, in the past two decades, the changing contexts of war brought the EOD community, and subsequently, these women to the forefront of combat preceding the 2016 policy repeal, positioning these women at a poignant, kairotic moment in history. The exigency of such a project in the field of rhetoric applies to more broadly analyzing the disparities between policy discourse and the lived experiences of individuals who …

Cyber Security- A New Secured Password Generation Algorithm With Graphical Authentication And Alphanumeric Passwords Along With Encryption, Akash Rao

Electrical & Computer Engineering Theses & Dissertations

Graphical passwords are always considered as an alternative of alphanumeric passwords for their better memorability and usability [1]. Alphanumeric passwords provide an adequate amount of satisfaction, but they do not offer better memorability compared to graphical passwords [1].

On the other hand, graphical passwords are considered less secured and provide better memorability [1]. Therefore many researchers have researched on graphical passwords to overcome the vulnerability. One of the most significant weaknesses of the graphical passwords is "Shoulder Surfing Attack," which means, sneaking into a victim's computer to learn the whole password or part of password or some confidential information. Such …

Estimation Of Arterial Wall Parameters Via Model-Based Analysis Of Noninvasively Measured Arterial Pulse Signals, Dan Wang

Mechanical & Aerospace Engineering Theses & Dissertations

This dissertation presents a model-based method for estimating arterial wall parameters from noninvasively measured arterial pulse signals via a microfluidic-based tactile sensor. The sensor entails a polydimethylsiloxane (PDMS) microstructure embedded with 5×1 transducer array built on Pyrex/Polyethylene terephthalate (PET) substrate. The arterial pulse causes a time-varying deflection on the top of the PDMS microstructure, which registers as a resistance change by the transducer at the site of the artery.

Owing to the time-harmonic nature of its radial motion, the arterial wall is modeled as a second-order dynamic system. By combining this dynamic model with a hemodynamic model of blood flow, …

Optical Excitation Of Metastable Krypton And Photoassociative Spectroscopy Of Ultracold Rbar, Grady R. White

Physics Theses & Dissertations

In this presentation, we discuss results from two separate bodies of work. In the first, we investigate all-optical excitation methods to produce metastable-state krypton. The high energies required to excite rare gases out of their ground state present a unique challenge in the context of laser experiments. Laser physics work with rare gases often relies on excitation within an RF discharge. All-optical excitation is a promising replacement for RF discharges, avoids problems caused by ion production and may eventually allow for higher efficiencies. We examine three separate methods of all-optical metastable-state production: using an ArF excimer laser, using the third …

Solid State Polyaniline Supercapacitors Based On Electrodes Fabricated With Electropolymerization, Jonathan R. Blincoe

Electrical & Computer Engineering Theses & Dissertations

Supercapacitors are energy storage devices with the potential to overshadow lithium-ion batteries in the energy storage sector. Generally supercapacitors store less energy than a lithium-ion battery, but make up for it with much higher power densities that allow supercapacitors to charge and discharge quickly. This can be through the formation of an electric double layer or faradaic phenomenon between the electrode and electrolyte. The energy storage mechanism relies heavily on the electrode material and the ions contained within the electrolyte. In this research, polyaniline was used as an active material to prepare supercapacitors. Polyaniline is a conductive polymer that is …

Save Money, Save Water; Developing A Risk Model For Leak Detection And Pipe Replacement Using Spatial Analysis, Angelique Desiree Maldonado

Water Resources Professional Project Reports

It is imperative to properly and proactively maintain a distribution pipe system. The benefits to optimizing a pipe distribution system include ensuring a safe water quality, reducing water loss from leaks and line breaks, minimizing revenue losses and providing a reliable service. There are also economic concerns as pipe replacement is extremely expensive; in the state of New Mexico, an estimated $1.16 billion in drinking water infrastructure is needed over the next 20 years. (USEPA 2013). Because distribution pipe is so costly to replace, an approach that only looks at age or type or non-system specific data may overestimate the …
