In the past, fisheries and aquaculture researchers in Africa have been handicapped by poor access to current scientific literature and difficulties in getting published in visible outlets. Efforts in the past decade to improve access, awareness and use of information have flourished. We examine whether these efforts are reflected in...

The feasibility of developing test circuits to perform in-circuit testing of analog
circuits is investigated in this thesis. A modular approach to analog testing has been
adopted. Accordingly, the testing of an operational amplifier, which is a basic building
block in analog circuits, is addressed. One convenient technique for measuring...
Library faculty are often tenure track, requiring a record of significant publishing and service before achieving tenure. However, meaningful tools and methods for evaluating the scholarship of librarianship frequently fall short of providing an accurate picture of the scholarship of any particular candidate. The authors conducted a case study analyzing...
Collaborative planning to streamline as well as to provide citizens with easier access to geospatial data has a long history in Oregon. A milestone in this process was the launch of the Oregon Spatial Data Library (OSDL) in November 2009. The Oregon Spatial Data Library is a joint effort between...
This has been a banner year for open access, and the momentum shows no sign of letting up. College and university faculties, and the granting agencies that fund a significant amount of their research, are increasingly embracing open access to ensure research findings across disciplines are freely accessible to the...
The Oregon ExplorerTM (www.oregonexplorer.info) strives to support informed decisions and actions by people concerned with Oregon's natural resources and environment. The Oregon Explorer's multi-media environment integrates archived digital documents, mapping and decision support tools, and finding aids for specific natural resource issues and topics. This paper presents the chronology of...
The article discusses effective methods for measuring the success of classroom instruction using original primary sources in special collections and archives and how to translate these effects to demonstrate learning impact that can be used in other assessment projects. The global economic crisis has reportedly pushed assessment activities in libraries...
This study evaluated the effects of pretreatment incising of dry lumber and preservative treatment on the shear strength of 1980 pieces of 2 X 4 dimension lumber (nominal 50 mm X 100 mm X 3.6 m long). Three species groups (Douglas-fir, Hem-Fir. and Spruce-Pine-Fir-South) and two commercially produced machine-stress-rated grades...
The objective of this work is to explore the feasibility of replacing conventional op-amps with inverters in switched-capacitor (SC) circuits. In order to verify the idea, a low-pass filter (LPF) and a second-order delta-sigma (∆Σ) analog-todigital converter (ADC) are designed in the 0.5-m CMOS technology. The low-pass filter structure is...
This report establishes an industry knowledge base for existing anchoring and mooring techniques as applied to wave energy conversion (WEC) devices in and around Oregon. This report on anchoring and mooring techniques is derived from the cumulative experiences of engineers and scientists with many years of experience analyzing, designing and...
Two large-resistance realisation schemes are proposed using switched-capacitor
circuits. The equivalent resistance of the array realisation
increases as the third power of the number of capacitor pairs, and
that of the ladder realisation increases exponentially. The equivalent
resistance for the ladder scheme also grows with the capacitance
ratio. Using these...
In this thesis, novel design techniques have been proposed for implementing high-linearity SC circuits in a standard digital CMOS process. They use nonlinear MOSFET capacitors instead of linear double-poly capacitors. To reduce their nonlinearities, a bias voltage is applied to keep MOSFET capacitors in their accumulation regions. For further reduction...
Ultraviolet-protective compounds, such as mycosporine-like amino acids (MAAs) and related gadusols produced by some bacteria, fungi, algae, and marine invertebrates, are critical for the survival of reef-building corals and other marine organisms exposed to high-solar irradiance. These compounds have also been found in marine fish, where their accumulation is thought...
The advance of digital IC technology has been very fast, as shown by rapid development of DSP, digital communication and digital VLSI. Within electronic signal processing, analog-to-digital conversion is a key function, which converts the analog signal into digital form for further processing. Recently, low-voltage and low-power have become also...
