NOARL's Remote Sensing Branch successfully carried out a demonstration programaimed at extracting sea ice formation from the Geosat altimeter signal. This effort significantly enhanced earlier limited studies done with the GOES-3 altimeter by incorporating the Automated Gain Control (AGC) and the Voltage Proportional to Attitude (VATT) parameters carried in the real-time data stream. These measures of the return pulse were combined in a ratio form to create an 'ice index,' so that all values less than a cutoff magnitude were characteristics of open water, while all remaining values above were sea ice. The altimeter footprint varies in size, depending on the surface roughness. In extremely smooth cases, the surface area in less than 1 km; in rough examples, it may be 5-7 km in areal extent. So, unless the altimeter footprint is fortuitously sampling a location where only one surface type is present (open water, first-year FY ice, multiyear MY ice, etc.), the altimeter waveform will be a mixture of returns from two or more surface types. In general, excellent results were achieved. Sea ice concentrations by ice type over the experiment area agreed with the surface truth to within 5%. When Fy and MY ice types were combined to give total ice concentration, the agreement was within 2%. Thus, linear unmixing has been shown to be a useful paradigm for extracing ice information from waveform shapes. However, this approach needs further investigation. In particular, the method of choosing end members. (i.e., the mixing polytope) in this effort was subjective. (TTL)

The Energy Regulatory Commission (ERC) established the Consumer Welfare Development (CWD) Program in June 2005, a project geared towards improving the customer service skills of the Philippine distribution sector in line with the mandate of the Electric Power Industry Reform Act (EPIRA). Through the assistance of the USAIDs Energy & Clean Air Project (ECAP), three (3) regional basic customer service trainings were conducted from July to August 2005 for Consumer Welfare Desk Officers (CWDOs) from select electric cooperatives (ECs) and private- utilities (DUs). From the three (3) batches, fifteen (15) outstanding participants were selected to undergo an advanced training program entitled TEACH (Teaching Experts and Advocates for Change) held last August 17-19, 2005. By virtue of graduation from the program, the candidates were given accreditation by the ERC as official CWD trainors. In line with the implementation of the CWD, the accredited trainors will be dispatched to conduct training workshops from March to May 2006 for the remaining CWDOs required to undergo a training on Basic Customer Service Skills. While the CWD trainors are required to organize and manage these workshops, they lack the project management skills to operationalize this task. An action planning workshop was necessary to address these concerns and to establish the support mechanism that the ERC and ECAP will jointly provide to ensure the completion of the objective by June 2006. This activity incorporates a CWD program review and refresher course, systems and processes assessment workshop, and strategic planning workshop.

The document contains the proceedings of the Tenth Annual Software Engineering Workshop held at the National Aeronautics and Space Administration (NASA)/Goddard Space Flight Center (GSFC) in Greenbelt, Maryland. The annual meeting is held to report and discuss experiences in the measurement, utilization, and evaluation of software methods, models, and tools. The workshop was conducted in four sessions: Research in the SEL; Tools for Software Management; Software Environments; Experiments with Ada; Twelve papers were presented. Over 400 persons representing 55 private corporations, 6 universities, and 27 agencies of the Federal Government attended the workshop.

These proceedings encompass outcomes from the DoD Cultural Resources Workshop: Prioritizing Cultural Resource Needs in Support of a Sound Investment Strategy, and reflect the views and opinions of workshop participants, and not necessarily those of the Department of Defense. HGL supported this workshop and produced the resulting proceedings document through funding awarded by the DoD Strategic Environmental Research and Development Program and Environmental Security Technology Certification Program (Omaha COE contract W9128F-04-D-0025, TO 0003), and by the DoD Legacy Resource Management Program (Huntsville COE contract W912DY-06-2-0009, project 06-294).

Currently there is much research activity in inversion for geoacoustic properties, both in the development of new methods, and in the application of existing methods to data from shallow water environments. Various techniques such as matched field inversion, matched field tomography, acoustic noise inversion, reflection coefficient inversion, acoustic travel time inversion, and horizontal wavenumber inversion have been investigated. The long term goal of this project is to contribute to the understanding of existing methods, and to the development of new methods for geoacoustic inversion.
