Colorimetric Oxygen Imaging And Quantification With Easily Accessible Optical Devices, Satya Achanta, Sanghan Park, Chang-Soo Kim

Electrical and Computer Engineering Faculty Research & Creative Works

Optical oxygen imaging is essential in monitoring two-dimensional analysis of oxygen distribution. Two easily accessible optical devices were used for oxygen analysis to demonstrate the feasibility of an innovatively simple method. a light panel screen with light-emitting diode (LED) backlight was used as a light source to excite a luminophore film responsive to oxygen. Meso-scale fluidic sensor platform was prepared using porphyrin complex (PtOEP) as the luminophore embedded within ethyl cellulose (EC) polymer matrix. Green LED light uniformly displayed from the light panel excited the luminophore film to exhibit two-dimensional luminescence distribution corresponding to wet gaseous oxygen. a color camera …

On Interference-Aware Precoding For Multi-Antenna Channels With Finite-Alphabet Inputs, Weiliang Zeng, Chengshan Xiao, Jianhua Lu

Electrical and Computer Engineering Faculty Research & Creative Works

This paper investigates the interference-aware linear precoder design with finite-alphabet inputs. It maximizes the mutual information between the transmitter and intended receiver while controlling the interference power caused to unintended receivers. for this nonconcave problem, this work proposes a global optimization approach, which is based on two key observations: 1) the interference-aware precoding problem can be reformulated to the problem minimizing a function with bilinear terms over the intersection of multiple co-centered ellipsoids; 2) these bilinear terms can be relaxed by their convex and concave envelopes. in this way, the global optimal solution is obtained by solving a sequence of …

Single-Carrier Frequency-Domain Turbo Equalization Without Cyclic Prefix Or Zero Padding For Underwater Acoustic Communications, Longbao Wang, Jun Tao, Yahong Rosa Zheng

Electrical and Computer Engineering Faculty Research & Creative Works

A frequency-domain turbo equalization (FDTE) scheme without cyclic prefix (CP) or zero padding is proposed for single-carrier, multiple-input-multiple- output underwater acoustic communication. in the first iteration of the FDTE, the received continuous data stream is divided into consecutive blocks and a combined inter-block-interference (IBI) cancellation and overlapped windowing scheme is used to diagonalize each data block for low-complexity detection in the frequency domain. Since the second iteration, IBI cancellation and CP reconstruction are applied on each block to enable effective symbol detection. This work extends the authors previous work on frequency-domain hard-decision equalization to soft-decision turbo equalization so that it …

Video Compressive Sensing With 3-D Wavelet And 3-D Noiselet, Dao Lam, Donald C. Wunsch

Electrical and Computer Engineering Faculty Research & Creative Works

A new compressive video sampling method is investigated. as opposed to other video sampling methods for which processing is conducted on a single-frame basis, this method is applied on multiple frames of the video stream. by exploiting the extension of Wavelet to 3-D with the support of Noiselet 3-D and combining it with fast reconstruction algorithms, this framework produces successful results quickly while maintaining the quality of the video stream. Despite its simplicity, this new approach outperforms other sophisticated methods. © 2012 IEEE.

Online Optimal Control Of Affine Nonlinear Discrete-Time Systems With Unknown Internal Dynamics By Using Time-Based Policy Update, Travis Dierks, Sarangapani Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, the Hamilton-Jacobi-Bellman equation is solved forward-in-time for the optimal control of a class of general affine nonlinear discrete-time systems without using value and policy iterations. the proposed approach, referred to as adaptive dynamic programming, uses two neural networks (NNs), to solve the infinite horizon optimal regulation control of affine nonlinear discrete-time systems in the presence of unknown internal dynamics and a known control coefficient matrix. One NN approximates the cost function and is referred to as the critic NN, while the second NN generates the control input and is referred to as the action NN. the cost …

A Cross Layer Approach To The Novel Distributed Scheduling Protocol And Event-Triggered Controller Design For Cyber Physical Systems, Hao Xu, Sarangapani Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

In Cyber Physical Systems (CPS), multiple real-time dynamic systems are connected to their corresponding controllers through a shared communication network in contrast with a dedicated line. for such CPS, the existing scheduling schemes for instance Centralized or Distributed Scheduling schemes are unsuitable since the behavior of real-time dynamic systems is ignored during the network protocol design. Therefore, in this paper, a novel distributed scheduling protocol design via cross-layer approach is proposed to optimize the performance of CPS by maximizing the utility function which is generated by using the information collected from both the application and network layers. Subsequently, a novel …

Rssi-Based Localization In Cellular Networks, Lei Wang, Maciej Zawodniok

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents a novel RSSI based localization scheme that employs an existing cellular network infrastructure to perform trilateration. Traditional localization schemes employ RSSI-Based radial distance estimation and trilateration algorithm. However, in a realistic scenario, the RSSI measurements are distorted due to multipath fading thus introducing error in radial distance estimation. Moreover, the selection of the best three anchor cell towers with the lowest localization error is not explored. the proposed scheme improves localization accuracy using two, novel correcting and evaluating metrics: The Radial Distance Error Indicator (RDEI) and the Localization Error Indicator (LEI). the proposed RDEI metric is derived …

Optimum Multi-Hop Transmission Strategies For Energy Constrained Wireless Sensor Networks, Jingxian Wu, Yahong Rosa Zheng

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents optimum multi-hop transmission strategies (MHTS) for energy constrained wireless sensor networks (WSNs). Nodes in a multi-hop WSN need to transmit their own information and to relay each other's information to a base station (BS), and there are usually multiple available paths between a node and the BS. the optimum MHTS derived in this paper answers three questions: 1) how should a node divide its limited energy between the transmission of the self-information and the relay-information? 2) whether a single path or a combination of multiple paths should be used to route the information from a node to …

Serving Youth Who Are Serving Time: A Study Of The Special Education Services For Incarcerated Youth In A Short-Term Care Facility, Sachiko Hoshide

Doctoral Dissertations

This study examined the communication between sending court and community schools of a County Office of Education’s (COE) Alternative Education program and the receiving juvenile detention facility of a county in a Western state and how the communication between the two facilities affected the level of special education services provided to incarcerated youth, specifically the occurrence of 30-day placement IEPs. The juvenile detention facility was selected as a site because it was a lighthouse program, one of the few chosen to pilot the juvenile detention alternatives initiative (JDAI). JDAI sought to lower the number of incarcerated youth through viable alternatives …

Moral Foundation Theory And Marketing, Steve Lemay, James Coleman, Dave Mcmahon

Journal of Applied Marketing Theory

In setting the stage for Moral Foundations Theory (MFT), Jon Haidt (2004) identified five foundations of intuitive ethics: 1) harm/care; 2) fairness/reciprocity; 3) ingroup/loyalty; 4) authority/respect; 5) and purity/sanctity. Each foundation could have implications for the content of marketing messages, but this research is the first attempt to test those implications in specific markets with specific products. This research explores the practical, promotional uses of John Haidt’s Moral Foundation Theory. Haidt’s work shows a strong relationship between his moral foundations and political orientation. Since marketers can readily get political data at the county level in the United States, these foundations …

Consumer Response To Outsourced 1-800 Calls: It’S The Solution Not The Country, Richard Feinberg, Wenti Xu, Leigh Hokama

Journal of Applied Marketing Theory

The growth of call center outsourcing and its emergence as a political and economic issue may have obscured some very important business and consumer issues. It is believed by many that consumers cannot be satisfied when calls are outsourced (offshored to India for example). The purpose of this study is to understand the relationship between where a call is answered and what happened on that call. In this study call outsourcing is placed within the well understood area of country-oforigin effects. Two experiments were completed in which outsourced country was manipulated with call outcome (resolution or no resolution). The findings …

Reconstituting Constitutions—Institutions And Culture: The Mexican Constitution And Nafta: Human Rights Vis-À-Vis Commerce, Imer Flores

Georgetown Law Faculty Publications and Other Works

The aim of this Essay is threefold. First, this Essay will focus on the main characteristics of both the great transformation, experienced in the Mexican institutional economic framework during the last thirty-five years, in general, and within the past twenty years, in particular, that were made through constitutional reforms. In addition, the greater expectation that such structural reforms generated in the process of re-enacting the constitution in the political context, should be along the lines of human rights and separation of powers. Second, this Essay will attempt to bring into play the role of treaties in this transformational process, by …

The Impact Of President Felipe Calderón’S War On Drugs On The Armed Forces: The Prospects For Mexico’S “Militarization” And Bilateral Relations, George W. Grayson Dr.

Books, Monographs & Collaborative Studies

View the Executive Summary

In the absence of honest, professional civilian law-enforcement agencies, President Felipe Calderón assigned the military the lead role in his nation’s version of the “War on Drugs” that he launched in 2006. While the armed forces have spearheaded the capture and/or death of several dozen cartel capos, the conflict has taken its toll on the organizations in terms of deaths, corruption, desertions, and charges by nongovernmental organizations (NGOs) of hundreds of human rights violations. The nation’s Supreme Court has taken the first step in requiring that officers and enlistees accused of crimes against civilians stand trial …

A National Security Staff For The 21st Century, Jack A. Lecuyer Dr.

Books, Monographs & Collaborative Studies

View the Executive Summary

Our legacy 1947/1989 national security system is unsuited for the dynamic and complex global security environment that has developed since the end of the Cold War. Over time, the National Security Council has evolved from the very limited advisory group initially imagined by President Truman to that of a vast network of interagency groups that were developed since 1989. These interagency groups view themselves as deeply involved in integrating policy development, crisis management, and staffing for the President. However, the National Security Staff (NSS) and the national security system are relics of the industrial age—vertical stovepipes—in …

Thin 3d Multiplication Regions In Plasmonically Enhanced Nanopillar Avalanche Detectors, Pradeep Senanayake, Chung-Hong Hung, Alan C. Farrell, David A. Ramirez, Joshua Shapiro, Chi-Kang Li, Yuh-Renn Wu, Majeed M. Hayat, Diana L. Huffaker

Electrical and Computer Engineering Faculty Research and Publications

We demonstrate a nanopillar (NP) device structure for implementing plasmonically enhanced avalanche photodetector arrays with thin avalanche volumes (∼ 310 nm × 150 nm × 150 nm). A localized 3D electric field due to a core–shell PN junction in a NP acts as a multiplication region, while efficient light absorption takes place via surface plasmon polariton Bloch wave (SPP-BW) modes due to a self-aligned metal nanohole lattice. Avalanche gains of ∼216 at 730 nm at −12 V are obtained. We show through capacitance–voltage characterization, temperature-dependent breakdown measurements, and detailed device modeling that the avalanche region is on the order of …

On Cowbells In Rock Anthems (And Property In Ip): A Review Of Justifying Intellectual Property, Eric R. Claeys

San Diego Law Review

I am going to start this Article with two confessions. First, when I was fourteen, my favorite rock song was (Don’t Fear) The Reaper, by Blue Oyster Cult. Second, one of my favorite Saturday Night Live (SNL) sketches is from the 2000 season, “Behind the Music: Blue Oyster Cult.” The sketch is a tribute in memory of Gene Frenkle, the member of Blue Oyster Cult who played the cowbell on (Don’t Fear) The Reaper. The SNL sketch purports to explain how the cowbell made it onto the studio recording. In the sketch, members of the regular SNL cast pretend to …

A Lockean Theory Of Intellectual Property Revisited, Adam D. Moore

San Diego Law Review

The primary, and perhaps sole, function of government according to Locke was to secure and protect the lives, liberties, and property of individuals who consented, explicitly or tacitly, to a specific political union. The question that I will address in this Article, and one that I took up over fifteen years ago, is: should we consider intellectual works to be the proper subjects of Lockean property claims? My answer then and now is “yes,” with the acknowledgement that such a view may require substantial revisions to Anglo-American systems of intellectual property. I will argue that intellectual property rights are no …

Toward A Lockean Moral Justification Of Legal Protection Of Intellectual Property, Kenneth Einar Himma

San Diego Law Review

This Article attempts to provide the beginnings of a viable moral justification for recognizing and providing legal protection of intellectual property. The argument follows a line of arguments that is fairly characterized as “inspired” by John Locke’s attempt to justify legal protection of what he took to be a natural, objective, moral right to material property. That is to say, it is Lockean in spirit in the following sense: Locke grounds his argument for original acquisition in the idea that a person is justified in acquiring something from the commons in virtue of an investment he makes of something that …

Access And The Public Domain, Randal C. Picker

San Diego Law Review

[T]his Article sketches out the emerging public domain. Part III considers three conceptual questions for structuring use of the public domain, focusing on the extent to which the public domain should be viral; on whether we should insist that the public domain be accessed only through the original artifacts embodying it; and on whether private appropriability incentives for distribution of public domain scans match overall social interests. Part IV turns to the tools for restricting use of the public domain, to copyright, contract, the DMCA, and the CFAA. Each of these matters for access to the public domain and for …

Patents As Promoters Of Competition: The Guild Origins Of Patent Law In The Venetian Republic, Ted Sichelman, Sean O'Connor

San Diego Law Review

[T]his Article describes the artisan and merchant guild systems of the Venetian Republic. Part III explores the emergence of the patent system as a means for foreigners and Venetian citizens to compete with the guilds, as well as the eventual addition of negative exclusive rights to the basic license form of positive patent privileges. In so doing, contrary to the speculation of some scholars, we reject with near certainty the contention that the first patent law statute granting exclusionary rights for—in modern parlance—technological inventions was a silk-specific directive enacted by the Venetian Grand Council in the late fourteenth or early …

Transition Relief For Tax Reform’S Third Rail: Reforming The Home Mortgage Interest Deduction After The Housing Market Crash, Nicholaus W. Norvell

San Diego Law Review

This Comment argues that Congress should—in this order of preference—eliminate the mortgage interest deduction, replace it with a credit, or substantially modify it, and that Congress can adopt any of these policies without substantial short-term fallout in the housing market. Part II of this Comment examines how the mortgage interest deduction works, its history, and its intended benefits. Part III scrutinizes the deduction’s inability to achieve its primary objective—increasing homeownership—and examines its negative effects on housing prices, household indebtedness, the environment, and wealth disparity. Accordingly, this Part argues that Congress should reform the deduction, discusses three basic options available for …

Does Therapist Guidance Enhance Assessment-Based Feedback As Couple Relationship Education?, W. Kim Halford, Raylene Chen, Keithia L. Wilson, Jeffry Larson, Dean M. Busby, Thomas Holman

Faculty Publications

Assessment and feedback of relationship strengths and challenges is a widely used brief approach to couple relationship education (CRE). It can be fully automated through the internet, with couples self-interpreting the feedback. This study assessed whether therapist guidance of couples to interpret the report and develop relationship goals enhanced the benefits of the feedback. Thirty-nine couples seeking CRE were randomly assigned to either self-interpretation of an internet-based relationship assessment report (RELATE), or therapist-guided interpretation of the same report (RELATE+). Participants were assessed on relationship satisfaction and psychological distress pre- and post-CRE, and a 6-month follow-up. RELATE and RELATE+ were not …
