All-Optical Network Coding
(2010-04)In this paper, we investigate the application of network coding to all-optical networks from both the algorithmic and infrastructural perspectives. We study the effectiveness of using network coding for optical-layer ... -
The Anglo-Indian community in contemporary India
(1971)The Anglo-Indian Community of today's India continues to face many of the problems familiar to past generations. They continue to exist as a discrete entity finding themselves threatened by nationalism and rising “All-India” ... -
Building A Thriving CS Program In A Small Liberal Arts College
(CCSC, 2011)In this paper we describe several techniques that have helped increase enrollment in the computer science program from 23 computer science majors in 2008 to 42 computer science majors in 2010 – an increase of 82.6%. We ... -
Classifying Networks For Network Coding
(MICS, 2011-04)Network coding is a relatively recent development in the realm of maximizing information transfer in communications and computer networks. Traditional networks operate by simply storing and forwarding data along. Network ... -
"Close-coupling and distorted-wave calculations for electron-impact excitation of the (5p56p) states of xenon"
(American Physical Society, 2004-06)We report on a series of calculations for electron impact-excitation of the (5p^5)6p states in xenon from the ground state (5p^6)^1S_0. As in previous calculations for other noble-gas targets, we find strong evidence of ... -
Design Of An All-Optical WDM Lightpath Concentrator
(PDCS, 2010-11)A design of a nonblocking, all-optical lightpath concentrator using wavelength exchanging optical crossbars and WDM crossbar switches is presented. The proposed concentrator is highly scalable, cost-efficient, and can ... -
Discovering homelessness: teaching, scholarship, and the real world
(2005-05-11)Annual Stalnaker Lecture Series at Drake University, focuses on the outcome of that grant, as well as the experiences both Wright and his students shared in searching out those in the Des Moines community who lived in ... -
"Distributed routing algorithms for multi-hop ad hoc networks using d-hop connected d-dominating sets"
(Elsevier Science, Inc., 2005-04-22)This paper describes a distributed algorithm (generalized d-CDS) for producing a variety of d-dominating sets of nodes that can be used to form the backbone of an ad hoc wireless network. In special cases (ordinary d-CDS), ... -
"Distributed routing schemes for ad hoc networks using d-SPR sets"
(Elsevier Science, 2004-10)In this paper, we propose several new distributed algorithms for producing sets of nodes that can be used to form backbones of an ad hoc wireless network. Our focus is on producing small sets that are d-hop connected and ... -
"The effect of income choice on bias in policy decisions made using cost-benefit analyses"
(Elsevier Science Incorporated, 2004-12-01)Cost-Benefit Analysis (CBA) is often used in policy decisions to determine the economic value of various choices. Although the effects of income disparity are well accepted, one of the reasons for the success of this ... -
"Effects of timber harvest on forest lepidoptera: community, guild, and species responses"
(Ecological Society of America, 2002)Abstract. Two pressing questions for forestry and conservation biology are whether periodic logging in forest ecosystems significantly changes biodiversity and whether the changes can be mitigated through appropriate harvest ... -
Electronic Guide to Wildflowers: Maintaining an Online Database for Natural Areas
(Mason City, Iowa : North Iowa Area Community College, 2001)An online guide to wildflowers of the Saylorville Lake Recreation Area, Des Moines River Basin, Polk Co., Iowa, is maintained as a public information project in cooperation with the U.S. Army Corps of Engineers. Each ... -
"Evaluation of high-dose estrogen and high-dose estrogen plus methyltestosterone treatment on cognitive task performance in postmenopausal women"
(S Karger AG (Basel, Switzerland), 2002)Objectives: To investigate the cognitive effects of high-dose oral estrogen alone or in combination with oral methyltestosterone in postmenopausal women. Methods: Participants were tested with a randomized, double-blind ... -

Generating Interest In Computer Science Through Middle-School Android Summer Camps
(CCSC, 2013-05)We conducted a week-long summer camp to promote interest in computer science among middle-school students. The camp primarily used self-paced video tutorials to teach programming concepts using the App Inventor for Android ... -
"Hierarchical routing in sensor networks using κ-dominating sets "
(Springer-Verlag, 2005)For a connected graph, representing a sensor network, distributed algorithms for the Set Covering Problem can be employed to construct reasonably small subsets of the nodes, called k-SPR sets. Such a set can serve as a ... -
"Human sex differentiation: From transcription factors to gender"
(S Karger AG (Basel, Switzerland), 2000)Over the past decade, knowledge of the genetic control of human sex differentiation has greately expanded our understanding of the developmental processes needed to form a male or female. The purpose of this review is to ... -

"Inertia of the stein transformation with respect to some nonderogatory matrices"
(Elsevier Science, 1996-07)Let A be an n-by-n nonderogatory matrix all of whose eigenvalues lie on the unit circle, and let and be nonnegative integers with + = n. Let ′ and ′ be positive integers and ′ a nonnegative integer with ′ + ′ + ... -
Intraspecific aggregation decreases local species diversity of arthropods
(Ecological Society of America, 2003)Abstract. The aggregation model of species coexistence predicts that insect species diversity within a community is maintained by intraspecific aggregation among resource patches. An untested corollary of this prediction ...
