Web Reviews: Nsf Data Management Plan: A Primer, Lisa Johnston

Sci-Tech News

Breaking away from the usual format, this month I’ve decided to focus on a hot topic that should be on the minds of anyone who deals with science and technology researchers and organizations: the National Science Foundation (NSF) Data Management Plan (DMP). This new requirement will open the door to many new conversations with our users about how they manage their data and what we, as library and information professionals, can do to help preserve and disseminate their research data for future generations of researchers. You may use this column as a guide to getting started on developing your own …

The Phenomenology Of The Bachelor Of Science In Hvac Engineering Technology From Ferris State University, Michael Feutz

Dissertations

Career and Technical Education (CTE) has evolved from industry-specific training to a more broad-based education that incorporates core academic learning objectives and prepares the student for work (Rothwell & Gerity, 2008; Uloa, 2006; Reese, 2002; Rojewski, 2002; Stone, 2002; Schmidli, 2001). Little is known about how well individual programs align with the industry for which graduates are prepared, (Zinser, 2003) or what CTE has meant to its graduates.

This research focused on graduates of the Bachelor of Science in Heating, Ventilation and Air Conditioning Engineering Technology (HVAC-ET) at Ferris State University in Big Rapids, Michigan. A phenomenological design was used …

It features stories about people who exist on the fringes of the human experience, from a man who infects himself with hookworms in an effort to cure his severe allergies to a woman who discovers a deaf man who has no language. It also features stories about groups of people on the edges of the human experience, including a community that refuses to leave its town, even though a fire is burning a hundred and fifty feet beneath it and a …

A Structure First Image Inpainting Approach Based On Self-Organizing Map (Som), Bo Chen, Zhaoxia Wang, Ming Bai, Quan Wang, Zhen Sun

Research Collection School Of Computing and Information Systems

This paper presents a structure first image inpainting method based on self-organizing map (SOM). SOM is employed to find the useful structure information of the damaged image. The useful structure information which includes relevant edges of the image is used to simulate the structure information of the lost or damaged area in the image. The structure information is described by distinct or indistinct curves in an image in this paper. The obtained target curves separate the damaged area of the image into several parts. As soon as each part of the damaged image is restored respectively, the damaged image is …

Automobile Exhaust Gas Detection Based On Fuzzy Temperature Compensation System, Zhiyong Wang, Hao Ding, Fufei Hao, Zhaoxia Wang, Zhen Sun, Shujin Li

Research Collection School Of Computing and Information Systems

A temperature compensation scheme of detecting automobile exhaust gas based on fuzzy logic inference is presented in this paper. The principles of the infrared automobile exhaust gas analyzer and the influence of the environmental temperature on analyzer are discussed. A fuzzy inference system is designed to improve the measurement accuracy of the measurement equipment by reducing the measurement errors caused by environmental temperature. The case studies demonstrate the effectiveness of the proposed method. The fuzzy compensation scheme is promising as demonstrated by the simulation results in this paper.

A Test-Bed For Secure Hierarchical Data Aggregation In Wireless Sensor Networks, Vimal Kumar, Joshua Mccarville-Schueths, Sanjay Madria

Computer Science Faculty Research & Creative Works

Data aggregation is a technique used to conserve battery power in wireless sensor networks (WSN). When securing such a network, it is important that we minimize the number of computationally expensive security operations without compromising on the security. This paper deals with the test-bed implementation of our end-to-end secure data aggregation algorithm. Unlike previous algorithms which required separate phases for secure aggregation and integrity verification, ours does not require an additional phase for verification. This saves energy by avoiding additional transmissions and computation overhead on the sensor nodes. We have implemented our secure data aggregation algorithms on mica2 motes. ©2010 …

Polymer (Su-8) Optofluidic Device With Embedded Hydrogel Oxygen Sensing Elements, Zhan Gao, David B. Henthorn, Chang-Soo Kim

Chemical and Biochemical Engineering Faculty Research & Creative Works

The SU-8 photopolymer is an excellent alternative for traditional materials used in fluidic devices such as glass- or silicon-Based inorganic materials. We describe a new chemically anchored, lithographically patterned hydrogel sensing element embedded in a completed SU-8 fluidic channel structure after the channel bonding process. Polyethylene glycol (PEG) hydrogel films incorporating oxygen-responsive ruthenium-complex fluorophores are grafted and patterned by photopolymerization of solution-phase precursors on the modified SU-8 channel surface. the optofluidic sensing platform with this embedded sensing elements exhibited excellent performance in measuring dissolved oxygen content. a unique advantage of this method is the selective growth of various functional films …

Active Bundles For Protecting Confidentiality Of Sensitive Data Throughout Their Lifecycle, Lotfi Ben Othmane

Dissertations

Protecting confidentiality of shared sensitive data requires satisfying conflicting needs for disseminating data and preventing unauthorized data disclosures. We propose a solution named the active bundles scheme for protecting sensitive data from their disclosures to unauthorized parties during their dissemination. The scheme protects data throughout their entire lifecycle, from data creation through their dissemination to their evaporation or apoptosis (a partial or complete self-destruction, respectively).

An active bundle packages together sensitive data, metadata, and a virtual machine (VM) specific to the bundle. Metadata contain information related to the use of data, including data access control and dissemination policies. A VM …

Rare Earth Element Transport In The Yucca Mountain Region, Liqiong Zhang

UNLV Theses, Dissertations, Professional Papers, and Capstones

In sync with environmental pollution of solutes in nature, from source, process to consequence, geochemical processes (leaching and sorption) and hydraulic transportation of the rare earth elements (REEs) have been investigated at Yucca Mountain (YM), Nevada. This research includes the leaching behavior of trace elements (including REEs) from aquifer rocks, the surface complexation reactions of REEs in synthetic groundwater, and transportation of reactive REEs in the local-scale groundwater system of YM. This dissertation includes three projects. These studies indicate that surface complexation reactions may retard the transportation of REEs along groundwater paths in YM, which suggests a similar behavior of …

Minimizing Base Column Demands In Multi-Story Buckling Restrained Braced Frames Using Genetic Algorithms, Christopher Hiroshi Yeates

Theses and Dissertations

Most structural optimization procedures focus on minimizing the total volume of steel in an attempt to reduce overall costs. However, many other factors can have an effect on the overall cost of a structure. Base column demands in particular, can affect base plate sizes, anchorage, and foundation design. Researchers have found that present methods for estimating column demands are too conservative. Nonlinear time history analyzes were conducted on buckling-restrained braced frames of six heights. Optimized results were found considering three ductility constraints and two optimization objectives. The two optimization objectives were minimized total brace area and minimized base column demands. …

An Investigation Of Carrier Transport In Hafnium Oxide/Silicon Dioxide Mos Gate Dielectric Stacks From 5.6-400k, Richard G. Southwick Iii

Boise State University Theses and Dissertations

Hafnium oxide (HfO₂) is replacing silicon dioxide (SiO₂) as the gate dielectric in metal oxide semiconductor (MOS) structures driven mainly by need to reduce high leakage currents observed in sub-2nm SiO₂. The high dielectric constant of HfO₂ (~25) compared to SiO₂ (3.9 bulk) allows a thicker HfO₂ layer to be used in place of the thinner SiO₂ layer thereby reducing the gate leakage current in MOS devices while maintaining the same capacitive coupling provided by the thinner SiO₂. However, incorporating HfO₂ into MOS devices produces a SiO …

Pickling Behavior Of Aisi 304 Stainless Steel In Sulfuric And Hydrochloric Acid Solutions, W Homjabok, S Permpoon, G Lothongkum

Journal of Metals, Materials and Minerals

Oxide scales as well as a Cr-depleted layer, which grows between the oxide scale and base metal, are formed on AISI 304 stainless steel surface during high temperature processing. Pickling is an important process which includes mechanical and chemical operations to remove oxide scales, Cr-depleted layers, and to recover the surface passivity. The multi-step pickling is commonly used because of its higher efficiency than a single step pickling. In this study, the multi-step pickling of AISI 304 stainless steel in HCl solution was investigated instead of H2SO4 solution for the first step of pickling. HF+HNO3 mixed acid is traditionally used …

Development Of An Aluminum Semi-Solid Extrusion Process, T Rattanochaikul, S Janudom, N Memongkol, J Wannasin

Journal of Metals, Materials and Minerals

Semi-solid extrusion process is a new forming process that is quite promising because the process requires lower forming pressure than conventional solid extrusion. In addition, semi-solid extrusion does not require large machines, which results in lower production costs. The aim of this article is to study the feasibility of an aluminum semi-solid extrusion process. The semi-solid technique selected for usage in this study was the Gas Induced Semi-Solid (GISS) process. The laboratory extrusion system was developed in this work. In the experiments, nitrogen gas was injected into aluminum melt for about 5 seconds. After that, the obtained semi-solid slurry was …

Development Of Layered Zn-Fe Coatings For Better Corrosion Protection, R S. Bhat, R Udupak, A C. Hegde

Journal of Metals, Materials and Minerals

In this research, the Zn-Fe coating having successive layers of alloys of two different compositions were developed alternatively on mild steel for better corrosion protection. The multilayer coatings, or alternatively, composition modulated alloy (CMA) coatings of different configurations have been developed, and their corrosion behaviors were evaluated by electrochemical DC and AC methods. The cyclic cathode current densities and numbers of layers have been optimised for peak corrosion stability of the coatings. Under optimal condition, the CMA coating having 300 layers, having about 67 nm average thickness was found to be approximately six times higher corrosion resistant than monolayer coating …
