IS-95, an interim standard proposed for future digital personal communications
systems, uses two levels of encoding of digital data for error control and compatibility
with code-division multiple access (CDMA) transmission. The data is first
convolutionally encoded and the resulting symbols are interleaved and then groups are
encoded as orthogonal Walsh...
This article describes a grant-funded project with the final goal of creating information literacy collaborative partnerships among academic, school, and public libraries. The objectives of the grant as well as an overall description of the project are stated. The emphasis of the article is on the process followed to create...
Measuring the effectiveness of library instruction poses many challenges, yet is essential to validating the time and energy dedicated to it. Over two years, how subject specific library instruction addressed the needs of the students, the instructor and the librarians was studied. Students were surveyed; librarians analyzed their research paper...
Assessing students' information literacy skills can be difficult depending on the involvement of the librarian in a course. To overcome this, librarians created an assignment called the Paper Trail, where students wrote a short essay about their research process and reflected on what they would do differently. Through reviewing and...
Atmospheric methane (CH₄) recorded in Antarctic ice cores represents the closest ice proxy available for Greenland temperature changes beyond times when Greenland climate records are available. The record over four climatic cycles from the Vostok ice core offers the opportunity to study the phase relationship between Greenland and Antarctic climate...
The Coastal Ocean Advances in Shelf Transport (COAST) program conducted an
interdisciplinary study of coastal upwelling off central Oregon during summer 2001.
Two intensive field efforts during May–June and August 2001 were coordinated with
ocean circulation, ecosystem, and atmospheric modeling of the region. A primary
goal was to contrast the...
Most administrators and ecologists agree that reducing the levels of hazardous fuels on forests is essential to restore healthy
watersheds and protect adjacent human communities. The current debate over the appropriateness, technique, and timing of treatments
utilized to restore vegetation structure and composition is currently on-going at local, state, and...
Successful fire exclusion in the 20th century has created severe fire problems across the West. Not every forest is at risk of
uncharacteristically severe wildfire, but drier forests are in need of active management to mitigate fire hazard. We summarize a
set of simple principles important to address in fuel...
A time series of hourly surface current maps in the shelf waters off Newport, Oregon,
was made during April–September 2001 using five SeaSonde HF current mappers, during
Coastal Advances in Shelf Transport (COAST). The surface currents responded rapidly
to the changing winds, in repeated patterns that were strongly affected by...
With growing concerns on environment impact of industrial product development, the product developers are seeking better solutions to achieve desired environmental benign requirements by the regulators and customers besides economic growth. During the last decade, some of the most successful product development companies (such as HP) have established their own...
