Joint Resource Provisioning In Optical Cloud Networks, Pan Yi 2016 University of Nebraska-Lincoln

Joint Resource Provisioning In Optical Cloud Networks, Pan Yi

Computer Science and Engineering: Theses, Dissertations, and Student Research

Resource allocation is an evolving part of many Cloud computing and data center management problems. For infrastructure as a service (IaaS) in the Cloud, the Cloud service provider allocates virtual machines (VMs) to the customers with required CPU, memory and disk configurations. In addition to the computing infrastructures, the bandwidth resources would also be allocated to customers for data transmission between reserved VMs. In the near future, users may also want to reserve multiple virtual data centers (VDCs) to construct their own virtual Cloud, which could be called data center as a service (DCaaS). For these two types of services ...


Memristor Panic—A Survey Of Different Device Models In Crossbar Architectures, Walt Woods, Mohammad Mahmoud A. Taha, Dat Tran, Jens Burger, Christof Teuscher 2016 Portland State University

Memristor Panic—A Survey Of Different Device Models In Crossbar Architectures, Walt Woods, Mohammad Mahmoud A. Taha, Dat Tran, Jens Burger, Christof Teuscher

Christof Teuscher

The popularity of memristors has led to a wide range of models being proposed for both physically realized devices and their concepts in general. These models have been fit to specific devices, but the resulting device models are not often discussed in relation to specific applications. A common tool in neuromorphic algorithms, crossbar architectures rely exclusively on the electrical properties of the device connecting rows to columns. Using memristors for these connections, we investigate the viability of 14 device models found in literature for this application. We look at these device models in a crossbar architecture, with supporting circuitry clocked ...


Successful Female Students In Undergraduate Computer Science And Computer Engineering: Motivation, Self-Regulation, And Qualitative Characteristics, Melissa Patterson Hazley 2016 University of Nebraska-Lincoln

Successful Female Students In Undergraduate Computer Science And Computer Engineering: Motivation, Self-Regulation, And Qualitative Characteristics, Melissa Patterson Hazley

Public Access Theses and Dissertations from the College of Education and Human Sciences

Computer Science (CS) and Computer Engineering (CE) fields typically have not been successful at recruiting or retaining women students. Research indicates several reasons for this shortage but mainly from three perspectives: social issues, exposure/prior knowledge and curriculum issues in K-12 settings. This mixed-methods research addresses a gap in the literature by investigating the motivation and self-regulation behaviors of successful female students who are studying computer science and computer engineering. The findings in phase one of this study indicated that learning and performance approach goals predicted adaptive strategic self-regulation behaviors including strategy use, knowledge building and engagement. Learning avoidance goals ...


Ac Power Monitoring System Provides Individual Circuit Energy Consumption Data, Jared L. Newman, Grayson H. Dearing, Luke M. Tomlinson, Frederick G. Harmon 2016 Cedarville University

Ac Power Monitoring System Provides Individual Circuit Energy Consumption Data, Jared L. Newman, Grayson H. Dearing, Luke M. Tomlinson, Frederick G. Harmon

The Research and Scholarship Symposium

Motivated by high energy costs, people and organizations want to cut back on their energy consumption. However, the only feedback consumers typically receive is a monthly bill listing their total electricity usage (in kWh). Some companies have begun developing systems that allow households and organizations to monitor their energy usage for individual circuits. Available systems are expensive so a CU engineering senior design team has designed, fabricated, and tested a system for use at Cedarville University. The AC power monitoring system has the ability to measure energy consumption for each individual circuit in the breaker panel, store the data, and ...

Role Of Diffusive, Photovoltaic, And Thermal Effects In Beam Fanning In Linbo3, Jaw-Jueh Liu, Partha P. Banerjee, Q. W. Song 2016 University of Alabama, Huntsville

Role Of Diffusive, Photovoltaic, And Thermal Effects In Beam Fanning In Linbo3, Jaw-Jueh Liu, Partha P. Banerjee, Q. W. Song

Partha Banerjee

We analyze the steady-state (Gaussian) beam fanning in LiNbO3 from the nonlinearly coupled Kukhtarev equations by including both diffusive and photovoltaic effects and by adding the thermal effect in the calculation. There is good agreement between theory and experiment. The results show a symmetric beam-fanning pattern whose size depends on the beam waist and the power. Possible applications of our results in nondestructive testing of material parameters and optical limiting are discussed.


Volume Holographic Optical Elements, Ching-Cherng Sun, Partha P. Banerjee 2016 National Central University

Volume Holographic Optical Elements, Ching-Cherng Sun, Partha P. Banerjee

Partha Banerjee

The final two papers are concerned with the analysis of novel holograms. Banerjee et al. investigate holographic recording and reconstruction for edge-lit holograms recorded in a 90-degree geometry. Various cases of recording and readout that incorporate propagational diffraction have been modeled. It is shown that the 90-degree geometry can result in beam shaping, as evidenced through preliminary experimental results with photorefractive lithium niobate. Nguyen et al. propose a new approach for designing computer-generated holograms. An artificial neural network is used to initiate the genetic algorithm so that the high computation cost of genetic algorithms for synthesizing holograms is significantly reduced ...

Partha Banerjee

Photorefractive polymers have been extensively studied for over two decades and have found applications in holographic displays and optical image processing. The complexity of these materials arises from multiple charge contributions, for example, leading to the formation of competing photorefractive gratings. It has been recently shown that in a photorefractive polymer at relatively moderate applied electric fields the primary charge carriers (holes) establish an initial grating, followed by a subsequent competing grating (electrons) resulting in a decreased two-beam coupling and diffraction efficiencies. In this paper, it is shown that with relatively large sustainable bias fields, the two-beam coupling efficiency is ...

Human Factors In The Development Of The Mobile Extreme Environment Research Station (Meers) Mission Control System (Mcs), Rebecca Demarco

Human Factors and Applied Psychology Student Conference

The developers for the MEERS MCS were required to develop a novel interface for their product. During the development of the MCS, analytical human factors methods and display principles were implemented to create the user interface. The methods and principles were also used so the MCS had a user centered design. The MCS went through several iterations of design. This presentation discusses the development process of the MEERS MCS from a human factors standpoint.

Animal Rights Talk: Moral Debate Over The Internet, Harold A. Herzog Jr., Beth Dinoff, Jessica R. Page

Harold Herzog

Messages sent over Animal Rights-Talk, an electronic mail network devoted to the discussion of issues related to the animal rights movement, were analyzed. Messages typically fell into the following categories: questions and information, discussions of philosophical issues, ethical problems associated with the treatment of particular species, the politics of the animal rights movement, problems of moral consistency, the ethics of particular uses of non-human species (e.g., meat consumption, biomedical research with animal subjects), and matters pertaining to the internal life of the network (e.g., efforts at control of perceived norm violations). Debates between animal activists and animal researchers ...


Chemical Dynamics Of Aluminum Nanoparticles In Ammonium Nitrate And Ammonium Perchlorate Matrices: Enhanced Reactivity Of Organically Capped Aluminum, William K. Lewis, Barbara A. Harruff-Miller, Joseph R. Gord, Andrew T. Rosenberger, Thomas M. Sexton, Elena A. Guliants, Christopher E. Bunker 2016 Air Force Research Laboratory

Chemical Dynamics Of Aluminum Nanoparticles In Ammonium Nitrate And Ammonium Perchlorate Matrices: Enhanced Reactivity Of Organically Capped Aluminum, William K. Lewis, Barbara A. Harruff-Miller, Joseph R. Gord, Andrew T. Rosenberger, Thomas M. Sexton, Elena A. Guliants, Christopher E. Bunker

Elena A. Guliants

Aluminum nanoparticles have been a subject of active investigation in recent years because of their potential to enhance the energy content of energetic materials. The associated kinetics of the chemical reaction and energy release are, in many cases, governed by the properties of the passivation layer protecting the particle rather than those of the underlying metal core. The passivation layer of Al particles is typically an oxide shell several nanometers thick, but other possibilities are now available. We have previously developed synthesis routes to produce air-stable Al nanoparticles that are capped by oleic acid. In the present study, we examine ...

Carbon Nanoparticles As Visible-Light Photocatalysts For Efficient Co2 Conversion And Beyond, Li Cao, Sushant Sahu, Parambath Anilkumar, Christopher E. Bunker, Juan Xu, K. A. Shiral Fernando, Ping Wang, Elena A. Guliants, Kenneth N. Tackett Ii, Ya-Ping Sun

Elena A. Guliants

Increasing atmospheric CO2 levels have generated much concern, driving the ongoing carbon sequestration effort. A compelling CO2 sequestration option is its photocatalytic conversion to hydrocarbons, for which the use of solar irradiation represents an ultimate solution. Here we report a new strategy of using surface-functionalized small carbon nanoparticles to harvest visible photons for subsequent charge separation on the particle surface in order to drive the efficient photocatalytic process. The aqueous solubility of the catalysts enables photoreduction under more desirable homogeneous reaction conditions. Beyond CO2 conversion, the nanoscale carbon-based photocatalysts are also useful for the photogeneration of H2 from water under ...

Investigating Security Attacks On Wireless Sensor Networks (Wsns) Via An Iot Environmental Monitoring System, Mauricio Tellez Nava, Samy El-Tawab, M. Hossain Heydari

Graduate Showcase of Scholarship and Creative Activities

To demonstrate our work, we have implemented a secure temperature monitoring system that makes use of the IEEE 802.15.4 standard, AES-128 hardware encryption and TelosB sensor nodes. In our design, we consider one of the nodes to be a coordinator node, which plays the role of a central node that establishes network association requests, listens for incoming packets, decrypts the incoming packets and forwards any received packets to the monitoring device. Three other nodes act as end-devices, which play the role of collecting temperature measurements, encrypting the collected data and sending the encrypted packets to the coordinator node ...

Data-Driven Modeling, Control And Tools For Cyber-Physical Energy Systems, Madhur Behl, Achin Jain, Rahul Mangharam

Real-Time and Embedded Systems Lab (mLAB)

Demand response (DR) is becoming increasingly important as the volatility on the grid continues to increase. Current DR approaches are completely manual and rule-based or in- volve deriving first principles based models which are ex- tremely cost and time prohibitive to build. We consider the problem of data-driven end-user DR for large buildings which involves predicting the demand response baseline, evaluating fixed rule based DR strategies and synthesizing DR control actions. We provide a model based control with regression trees algorithm (mbCRT), which allows us to perform closed- loop control for DR strategy synthesis for large commercial buildings. Our data-driven ...


Scalable Verification Of Linear Controller Software, Junkil Park, Miroslav Pajic, Insup Lee, Oleg Sokolsky 2016 University of Pennsylvania

Scalable Verification Of Linear Controller Software, Junkil Park, Miroslav Pajic, Insup Lee, Oleg Sokolsky

Departmental Papers (CIS)

We consider the problem of verifying software implementations of linear time-invariant controllers against mathematical specifications. Given a controller specification, multiple correct implementations may exist, each of which uses a different representation of controller state (e.g., due to optimizations in a third-party code generator). To accommodate this variation, we first extract a controller's mathematical model from the implementation via symbolic execution, and then check input-output equivalence between the extracted model and the specification by similarity checking. We show how to automatically verify the correctness of C code controller implementation using the combination of techniques such as symbolic execution, satisfiability ...
