Technical reports describe the process, progress, or results of technical or scientific research. They include in-depth experimental details, data, and results that are often sent to the funding organization (DOE, NASA and the Department of Defense are top funders) as a report of accountability. Technical reports are usually not peer-reviewed, so evaluation of how the problem, research method, and results are described is the responsibility of the reader.
