A cluster of computers can be used to render large amounts of data at very high resolutions. One application of clusters is scientific visualization, which often involves the display of large data sets. This paper describes a prototype system that allows oceanographers to interactively view oceanographic data using a cluster...
Generative programming is a paradigm that seeks to automate the manufacture of software products the same way other industries automated the manufacture of consumer, electric, and mechanical products. I examine how meta-programming fits into the context of generative programming and, along the way, expose theoretic and taxonomic deficiencies. In some...
Modern cryptanalysis is generally based on the mathematical theory. However, side-channel analysis has become increasingly popular recently. The benefit of side-channel cryptanalysis is due to the fact that performers can mount attacks with low costs in terms of time and equipment and are highly successful in extracting useful results. The...
This paper discusses Java Bytecode Obfuscation techniques that make the reverse engineering task more difficult. This paper is structured as follows: Java virtual machine and Java language specifications are discussed first. Then the paper talks about different techniques for protecting software and then details one promising approach named Obfuscation. The...
Shape transformation is a technique for gradually changing one geometric shape to another. A recent approach presents the use of thin-plate radial basis functions as opposed to traditional "blobby sphere" implicit functions. Without the explicit evaluation of he energy function, this approach combined the two traditional steps into one by...
Personalization is defined as a process that facilitates interaction among consumers and providers such that individual consumers are enabled to more readily access the content and services of providers, and individual providers are enabled to more effectively and easily deliver their content and services to consumers. This project presents a...
The WEPP (Water Erosion Prediction Project) application computes soil loss and sediment yield from a field based on the data on crops, management practices, and operations. In order to make WEPP, which is a Windows-based application, easily accessible, Web WEPP (Web-based WEPP) was developed by our research group.

The Façade photometric modeling system, developed by Paul E Debevec at Berkley, is capable of transforming a sparse set of camera images of an architectural scene into a photorealistic 3D model. Users define a rough model out of primitive building blocks and mark where a portion of the edges of...
Alignment of genomic sequences from different species is becoming an increasingly powerful method in biology, and is being used for many purposes. The result of sequence alignments is a list of pairs of matched locations between the pattern string and the text string. However, without any proper visualization tools to...
The concept of forest health has recently emerged as a focal concept for federal forest policy. At the same time, social and political conflicts over the characteristics of a healthy forest, and over the causes of poor forest health, underscore the lack of a shared understanding of what the term...
Effective watershed restoration planning and prioritization is often very difficult because decision making typically involves a large number of alternatives evaluated on the basis of multiple and often conflicting technical, social, economic, and environmental objectives and criteria. In order to solve such complex decision making problems, multiobjective decision making (MODM)...
Coral reef ecosystems are the most diverse on earth, and their subsistence is being threatened by natural and adverse anthropogenic patterns and processes. In an effort to understand and protect these marine environments, several programs have outlined strategies and initiatives. For example, the United States Coral Reef Task Force’s Mapping...

The Bureau of Land Managements (BLM) Emergency Fire Rehabilitation (EFR) policy was developed in 1985 to encourage protection of sites from soil erosion and to minimize potential changes in vegetation communities that may result from the dominance of weedy species. To achieve the goals of EFR policy, managers often used...
In this report, I first introduce three areas of interest to collaborative filtering researchers, namely: (a) how to solve the sparsity and scalability problems in recommendation systems; (b) how to rapidly develop and test collaborative filtering algorithms; and (c) how to apply collaborative filtering to unbounded numeric preference data. In...
Timing attacks enable an attacker to extract secret information from a cryptosystem by observing timing differences with respect to different inputs given to an encryption or decryption algorithm. Werner Schindler has proposed a timing attack on smart card devices. We implemented this attack based on the same approach for RSA...
Accreditation Board for Engineering and Technology, Inc.

download and installation process efficiency. A web-based software installation is...
"A non-redundant number system has the digit set limited ranging from 0 to radix -1. While the Signed digit numbers have digit set consisting of more than radix r values. Hence it is also called redundant number system. Furthermore, the advantage of redundant number system lies in its application for...
Ecoregions are regions of relative homogeneity with respect to specific
ecosystem variables (Bailey 1976; Omernik 1995). There has been an increasing
awareness that effective management of environmental resources must be undertaken
with an ecosystem perspective (Omernik, 1995). Ecoregions serve as a spatial
framework for assessing, managing, and monitoring ecosystems that...
A miniature reciprocating expander is being developed as part of a larger program to develop a heat actuated heat pump for portable applications.

substitution, were investigated in thin film p-type CuScO₂, a wide band gap
semiconductor with the delafossite structure. Films rf-sputtered onto amorphous SiO₂
substrates were polycrystalline after post-deposition annealing. X-ray diffraction was
used to determine that the films are predominantly polycrystalline 3R...

It has long been acknowledged that recreation activities can cause conflict
among stakeholders with different perspectives. In 1949, Aldo Leopold, one of the
earliest proponents of wilderness preservation, noted "Public policies for outdoor
recreation are controversial. Equally conscientious citizens hold opposite views on what
is and what should be done...
The present study investigated the effects of stress and exercise on seawater (SW) adaptation and cortisol dynamics in juvenile steelhead (Oncorhynchus mykiss). To examine the effects of stress, fish acclimated to freshwater (FW) were subjected for 3 hours to confinement stress in FW, and subsequently SW (25 ppt) was introduced...
The influence of streambank location and timing of herbivory on success of planted Booth's willow (Salix boothii Dorn) cuttings along a Rosgen C5-type stream in an eastern Oregon meadow was determined. Willow cuttings were planted on two morphological locations (i.e. point bar and floodplain) in May of 2002 and 2003....
We have performed fluorescence extended X-ray absorption fine structure (EXAFS) measurements on the Cd K-edge of partial electrolyte (PE) treated Cu(In[subscript 0.7]Ga[subscript 0.3])Se₂ (CIGS) thin film samples using synchrotron X-ray radiation. This data was compared to the EXAFS spectra of CdSe and CdO standards. Cd local structure models were constructed...
Monitoring reproductive success, prey species composition, and colony size of marine birds has been proposed as a method of assessing changes in marine systems that are otherwise difficult to sample (Cairns 1987). I measured inter-annual and intra-seasonal variability in reproductive parameters, taxonomic composition of the diet, and adult body condition...
Mitchell Marsh, a tidal salt marsh in the Salmon River Estuary, was diked in the
early 1960s. Restoration of the marsh, which began in late 1978, consisted of partial dike
removal. Several studies have been conducted in the marsh, addressing the status of the
developing salt marsh plant communities. Species...
Over 470 dams have been removed in the United States, and a significant increase in dam removals has
occurred since the early 1990s. The aging of dams is often cited as the primary factor influencing removals;
as dams surpass their functional life span, safety hazards, economic costs, and environmental concerns...
Legislation can be an effective public health tool, and understanding the factors that influence legislative outcomes is advantageous for public health practitioners who propose and advocate for legislation.
