Prediction Of Effective Permittivity Of Diphasic Dielectrics Using An Equivalent Capacitance Model, Sandeep K. Patil, Marina Koledintseva, Robert W. Schwartz, Wayne Huebner

Electrical and Computer Engineering Faculty Research & Creative Works

An analytical model based on an equivalent capacitance circuit for expressing a static effective permittivity of a composite dielectric with complex-shaped inclusions is presented. The dielectric constant of 0-3 composites is investigated using this model. The geometry of the capacitor containing a composite dielectric is discretized into partial parallel-plate capacitor elements, and the effective permittivity of the composite is obtained from the equivalent capacitance of the structure. First, an individual cell diphasic dielectric (a high-permittivity spherical inclusion enclosed in a lower permittivity parallelepiped) is considered. The capacitance of this cell is modeled as a function of an inclusion radius/volume fraction. …

Biomimetic Subwavelength Antireflective Gratings On Gaas, Chih-Hung Sun, Brian J. Ho, Bin Jiang, Peng Jiang

Mathematics and Statistics Faculty Publications and Presentations

We have developed a simple and scalable bottom-up approach for fabricating moth-eye antireflective coatings on GaAs substrates. Monolayer, non-close-packed silica colloidal crystals are created on crystalline GaAs wafers by a spin-coating-based single-layer reduction technique. These colloidal monolayers can be used as etching masks during a BCl_3 dry-etch process to generate subwavelength-structured antireflective gratings directly on GaAs substrates. The gratings exhibit excellent broadband antireflective properties, and the specular reflection matches with the theoretical prediction using a rigorous coupled-wave analysis model. These bioinspired antireflection coatings have important technological applications ranging from efficient solar cells to IR detectors

Link Layer Multicast Using Smart Antennas: No Client Left Behind, Souvik Sen, Jie Xiong, Rahul Ghosh, Romit Roy Choudhury

Research Collection School Of Computing and Information Systems

Wireless link layer multicast is an important service primitive for emerging applications, such as live video, streaming audio, and other content telecasts. The broadcast nature of the wireless channel is amenable to multicast because a single packet transmission may be received by all clients in the multicast group. However, in view of diverse channel conditions at different clients, the rate of such a transmission is bottlenecked by the rate of the weakest client. Multicast throughput degrades severely. Attempts to increase the data rate result in lower reliability and higher unfairness. This paper utilizes smart beamforming antennas to improve multicast performance …

Shattering And Moving Beyond The Gutenberg Paradigm: The Dawn Of The Electronic Will, Joseph Karl Grant

University of Michigan Journal of Law Reform

Legislators in Nevada have already acted to modernize the law of wills. This Article advocates that other states follow their lead and depart from what is described as the "Gutenberg Paradigm" by adopting similar legislation and embracing electronic technology. Part One of this Article explores the history of print, Johann Gutenberg's role in this development, and the emergence of the "Gutenberg Paradigm." Part Two examines the history and policy underpinnings of will execution formalities, and the role of the "writing" requirement. Part Three explores the use of electronic wills as conforming and nonconforming testamentary instruments. More specifically, Part Three highlights …

Liability For Lapses: First Or Second Order Negligence?, Robert D. Cooter, Ariel Porat

Coase-Sandor Institute for Law & Economics Research Paper Series

"First order precaution" directly affects the probability of an accident, such as judging the speed of a car and stepping on the brakes. Intentions are not always realized, so first order precaution is a draw from a probability distribution. Drawing an uncharacteristically low value is a "lapse." "Second order precaution" reduces the probability of a lapse. Examples include concentration when driving and preparation before performing a medical operation. The prevailing tort rule holds the injurer liable for harm caused by unreasonable first order precaution, regardless of second order precaution. Unlike the standard model, our model allows injurers to make second …

A Darwinist View Of The Living Constitution, Scott Dodson

Vanderbilt Law Review

There is much debate, and has been for some time, over whether we have a "living" Constitution, one that adapts to changing circumstances and evolves over time. The metaphor arose and gained initial force during the Progressive Era and has been at the forefront of the debate on constitutional interpretation ever since. There is a more recent division, most prominently marked by Professor Owen Jones and Professors Brian Leiter and Michael Weisberg, over whether biology has a meaningful role to play in legal developments. Professor Jones has written many articles promoting the potential utility of behavioral and evolutionary science to …

The Changing Usage Of A Mature Campus-Wide Wireless Network, Tristan Henderson, David Kotz, Ilya Abyzov

Dartmouth Scholarship

Wireless Local Area Networks (WLANs) are now commonplace on many academic and corporate campuses. As "Wi-Fi" technology becomes ubiquitous, it is increasingly important to understand trends in the usage of these networks. This paper analyzes an extensive network trace from a mature 802.11 WLAN, including more than 550 access points and 7000 users over seventeen weeks. We employ several measurement techniques, including syslog messages, telephone records, SNMP polling and tcpdump packet captures. This is the largest WLAN study to date, and the first to look at a mature WLAN. We compare this trace to a trace taken after the network's …

Designing More Effective Air Quality Advisories, Justin Olexy

Environmental Science and Management Professional Master's Project Reports

Background: There is increasing concern about the impact of air quality on human health in urban environments and how to best reduce impacts through public policies. An NSF Biocomplexity Project - "Feedbacks between Urban Systems and the Environment" (FUSE), led by Portland State University, studies the human feedbacks and responses to air quality and heat advisories through data collected in city-wide phone surveys in Portland, OR and Houston, TX. On days when ozone levels are predicted to exceed air quality standards, regulatory agencies issue air quality advisories which ask residents to reduce certain air polluting behaviors such as driving …

Northern Range Expansion And Coastal Occurrences Of The New Zealand Mud Snail Potamopyrgus Antipodarum (Gray, 1843) In The Northeast Pacific, Timothy Mathias Davidson, Valance E. F. Brenneis, Catherine E. De Rivera, Robyn Draheim, Graham E. Gillespie

Environmental Science and Management Faculty Publications and Presentations

The New Zealand mud snail Potamopyrgus antipodarum (Gray, 1843) is a common invasive species in fresh and brackish water ecosystems in Europe, Australia, Japan, and North America. In some invaded habitats, P. antipodarum can reach high densities (over 500,000 snails m^-2) and dominate the biomass of the benthos, leading to detrimental impacts to native biota and changes in ecosystem dynamics. We report the previously unpublished occurrence of P. antipodarum in thirteen fresh and brackish water systems adjacent to the Pacific coast of North America including a new northern range for P. antipodarum: Port Alberni, Vancouver Island, British …

Do Off-Campus Students Still Use Document Delivery? : Current Trends, Michele D. Behr, Julie L. Hayward

University Libraries Faculty & Staff Publications

The tremendous increase in the availability of full text electronic resources has been particularly beneficial to distance education students who do not have easy access to print collections. However Western Michigan University (WMU) has been experiencing a decrease in requests for traditional document delivery of print based materials. This article presents a case study of WMU document delivery services for the distance education community. A survey was also conducted of libraries serving distance education programs to determine whether other institutions are also experiencing a decrease in usage of document delivery. Survey results show a more universal trend toward decreasing requests …

Estatus Actual De Los Búhos Terrestres (Athene Cunicularia) En La Zona De Puerto López, Ecuador: Efectos De Las Creencias Y Sentimientos Hacía Los Animales Silvestres, Allison Qubain

Independent Study Project (ISP) Collection

In response to negative attitudes towards the existing biodiversity in the region of Puerto Lopez, Ecuador and as a follow-up of a study conducted in 2006 on the status of Burrowing Owl (Athene cunicularia) populations, through informal interviews and observation, this investigation focuses on how local sentiments towards nature have affected the current status of the Burrowing Owl populations and their habitat. The investigation revealed that in addition to the effects of legends and beliefs, there is an existing lack of knowledge, understanding, and appreciation for the extremely high biodiversity, which has created an evident fear instilled in the people. …

La Lucha Por Una Comunidad Sustentable Los Campesinos Tonocote De Breayoj: Manejo De Recursos, Desarrollo Y Elecciones, David Flannelly

Independent Study Project (ISP) Collection

A study about the environment and sustainability has to be soley about topics solely relating directly to nature, right? With this preconception in my mind I went off to study an indigenous subsistence farming community in the northwestern region of Argentina. Initially I solely wanted to focus on the management of resources of the community, the trees, water, and animals. Fate had other plans for my indepent study project. I arrived in the community right in the middle of the last week of historical elections for the province and the community. A new political party of farmers and other poor …

Corallivorous Reef Fishes As Potential Vectors Of Coral Disease Based On A Study Of Dietary Preferences, Tanya Rogers

Independent Study Project (ISP) Collection

The prevalence of coral disease appears to be increasing worldwide, although little is known about how these diseases are transmitted between coral colonies. To examine whether corallivorous fishes could potentially act as disease vectors, this study examined whether and which fish species feed on diseased coral, and whether these fishes actively target diseased coral sections. Branches of Acropora muricata with brown band disease were filmed in the field, and bites taken by fishes on different sections of the coral (live tissue, tissue margin, disease band, dead skeleton, and algae) were recorded. For each fish species, electivity indices were calculated for …

Taking into consideration past history of the area this report aims to examine the views of Hinchinbrook Area boaters and fishermen regarding conservation initiatives and indigenous hunting. A combination of surveying local boaters using a questionnaire and interviews conducted with local experts and people involved in dugong conservation resulted in both numeric results and many personal opinions.

Conservation initiatives include voluntary speed guidelines, voluntary transit lanes, and a Traditional Use of Marine Resource Agreement. Boaters’ opinions and compliance with all the initiatives was examined using a questionnaire which included a True or False section, personal opinions, compliance, and sighting information. …

Vertical Distribution Of Spiders (Araneae) On A Tropical Island, Eric Brown

Independent Study Project (ISP) Collection

The distribution of spiders into vertical layers was studied on Misali Island. In particular, differences in diversity, species richness, abundance, and body length were analyzed. A variety of collection methods were used in order to capture as many different species as possible from three levels of forest: leaf litter, groundcover (up to 1m), and understory (up to 3m). After being sorted to the morphospecies level, the spiders were cataloged and several statistical tests were run. These tests show that spiders do show species-level stratification between different levels of forest. They also pointed towards a particularly firm dividing line between species …

Improving Beekeeping On Unguja Island, Larken Root

Independent Study Project (ISP) Collection

The purpose of this study was to investigate the current practices and methods for improvement of beekeeping on Unguja Island in Zanzibar. Beekeeping has been occurring for many years in Unguja but has retained traditional techniques with little improvement. Improvement can occur in the form of introduction of modern equipment, formation of beekeeping organizations, advancing and diversifying products, and gaining governmental support. Beekeeping is worthy of expansion because of its potential to increase rural income in a sustainable way as well as support conservation of forest areas. The study found that there has so far been little improvement of income …
