Towards Deadline Guaranteed Cloud Storage Services, Guoxin Liu, Haiying Shen, Lei Yu

Publications

More and more organizations move their data and workload to commercial cloud storage systems. However, the multiplexing and sharing of the resources in a cloud storage system present unpredictable data access latency to tenants, which may make online data-intensive applications unable to satisfy their deadline requirements. Thus, it is important for cloud storage systems to provide deadline guaranteed services. In this paper, to meet a current form of service level objective (SLO) that constrains the percentage of each tenant's data access requests failing to meet its required deadline below a given threshold, we build a mathematical model to derive the …

Investing In Youth Work: Learning From Complexity, Kari Denissen Cunnien

Journal of Youth Development

This article proposes key elements for a system of support for youth workers to develop their professional skills and capabilities by using a human development approach. The article argues that narrowed and bureaucratic approaches to professional development can ignore the complex dynamics of human development that support engaged learning and continuous growth and improvement. The author suggests a more dynamic system where professional development in grounded by practice; employs reflection, mentorship and coaching; and supports healthy organizational culture to foster high quality youth work.

A Formative Experiment To Align Middle-School History Instruction With Literacy Goals, Jamie Colwell, David Reinking

Publications

Background/Context

Recent curricular trends based on new standards emphasize the centrality of reading and studying texts in history instruction. That trend suggests a closer alignment between middle-school history instruction and goals for developing literacy. Yet potential obstacles identified in the literature, particularly a teacher's stance toward teaching history, imply challenges to instantiating that alignment. Relatively little research has addressed how relevant conceptual positions such as disciplinary literacy might be realized in authentic practice.

Purpose/Objective

The objective was to investigate how middle-school history instruction could be transformed to align with the literacy goals addressed in new curricular standards and to better …

Boundary Controllability For One-Dimensional Wave And Heat Equations With Potential, Andrew Walton Green

All Theses

In this thesis we investigate the boundary controllability of the wave and heat equa-tions with bounded potential in one dimension. This is done by way of the observability inequality. For the wave equation, we use the Hilbert Uniqueness Method of J. L. Lions to show the observability inequality is sufficient for exact controllability. Observability is shown by the multiplier method when there is no potential and a special Exchange of Vari-ables technique for when potential is present. Due to limitiations of this method we also use a Carleman Estimate which can be extended to higher dimensions. For the heat equation, …

Uniform Micro-Patterning Of An Arbitrary Surface, Viraj Rajendra Kulkarni

All Theses

According to the literature, creating specific micro-level patterns on some surfaces can significantly reduce friction. To this effect, a method is presented to create a regular pattern of micro-level indentations on any irregular surface. Creating a uniform pattern on a regular surface is possible using commercial CAD software, where regular surface is the surface obtained by extrusion or revolution of a 2D sketch along any curve. But, it is complicated and often incorrect for irregular surfaces. The thesis presents the approach followed to create parameterized regular patterns on arbitrary surfaces. Three different algorithms are presented, each achieving a progressively increased …

Investigating Materials That Promote New Organic Methodology And Remediation Of Volatile Organic Compounds, Mckenzie Louise Campbell

All Dissertations

The need for environmentally safe reagents for the promotion of organic transformations is critical in order to reduce hazardous waste and byproducts associated with industrial-scale chemical processes. We have developed two practical methods that obviate the need for harsh oxidative and toxic brominating reagents in electrophilic halogenation reactions.

In our hands, a catalytic loading of the inexpensive, commercially available V2O5 (~$0.25/g) promotes the bromolactonization of a series of substituted alkenoic acids in isolated yields up to 97% by means of the in situ generation of bromenium (Br+) from bromide (Br−) at room temperature. This process obviates the need for molecular …

Simulation Of Reverse Osmosis And Osmotically Driven Membrane Processes, Peng Xie

All Dissertations

To address the increasingly severe global water shortage and pollution problem, reverse osmosis (RO) has been widely used because of its ability to produce high quality water. Meanwhile, related technologies have been developed, called osmotically driven membrane processes (ODMPs). These include forward osmosis (FO), which has potential for wastewater purification and desalination, and pressure retarded osmosis (PRO), which has the capacity to produce energy. The main problems associated with RO and ODMPs are concentration polarization and membrane fouling which deteriorate the quality and quantity of the permeate flux and increase the operating cost of the system. The task of this …

Exploiting The Principal Parametric Resonance Of An Rlc" Circuit For Vibratory Energy Harvesting", Nicholas B. Caldwell

The use of ambient energy sources to independently power small electronic devices, a process commonly known as energy harvesting, has recently become a focus of research due to advances in low-power electronic applications. A particular class of energy harvesting devices, known as vibratory energy harvesters (VEHs), utilizes low-level vibrations present in numerous natural and man-made environments to generate electrical energy for electronic devices.

This work investigates the use of a new technique to harvest energy from ambient vibrations by parametrically exciting a resonance condition of the electric current in a nonlinear oscillating circuit. To accomplish this parametric resonance phenomenon, we …

The Coronary Circulation In An In Vitro Multi-Scale Model Of The Stage 1 Norwood Procedure, Lauren Elizabeth Carter

All Theses

Hypoplastic Left Heart Syndrome (HLHS) is a congenital heart disease where the left ventricle and ascending aorta are underdeveloped. The first of three palliative surgeries for this malformation is the Norwood procedure. In this surgery, an opening is made between the left and right atrium so that all blood can flow into the right ventricle (RV). A reconstructed aorta is anastomosed (connected) to the RV so that the RV can pump oxygenated blood to the body (the systemic circulation). To divert part of the systemic blood flow to the pulmonary circulation, the modified Blalock-Taussig Shunt (mBTS) is connected from the …

Investigating Employee Engagement Through A Self-Determination Theory Framework, Crystal S. Wiedemann

Estimation Of Annual Average Daily Traffic (Aadt) And Missing Hourly Volume Using Artificial Intelligence, Sababa Islam

All Theses

Annual Average Daily Traffic (AADT) is one of the most important traffic parameters used in transportation engineering analysis. Moreover, each state Department of Transportation (DOT) must report the AADT data to Federal Highway Administration (FHWA) annually as part of the Highway Performance Monitoring System (HPMS) requirements. For this reason, state DOTs continually collect AADT data via permanent count stations and short-term counts. In South Carolina, only interstates and primary routes are equipped with permanent count stations. For the majority of the secondary routes, AADT data are estimated based on short-term counts or are simply guesstimated based on their functional classifications. …

A Semi-Analytical Unit Cell Synthesis Method For Design Of Meta-Materials With Targeted Nonlinear Deformation Response, Shanyun Gao

All Theses

A Unit Cell Synthesis Method was developed recently for designing meta-materials from unit cell level to achieve prescribed nonlinear deformation response. The method starts with a process of selecting and combining a set of elemental functional geometries (EFG) and elemental structural geometries (ESG) to form the unit cell structure. A subsequent size optimization is performed to obtain an optimal design which provides the targeted nonlinear deformation behavior. While the method is proven effective in producing feasible meta-material designs, the design and optimization of the unit cells relies heavily on nonlinear finite element analysis, which makes the overall process computationally intensive …
