April 2005 Welcome to The CTMA Connector, a monthly newsletter designed to provide news and ideas about the Commercial Technologies for Maintenance Activities (CTMA) program. The CTMA program is a joint Department of Defense/National Center for Manufacturing Sciences (DoD/NCMS) effort promoting collaborative technology development between industry and the DoD maintenance and repair facilities. This newsletter highlights ongoing projects, serves as a forum for promoting new project ideas, and provides other news of interest to the program. Our goal is to stimulate your participation and solicit your input. Feel free to submit items for the newsletter as well as any suggestions to make it more useful. More information about the program can be found at http://ctma.ncms.org/. To subscribe or unsubscribe to the CTMA Connector, send a message to listserv@listserv.ncms.org with "subscribe CTMANewsletter" or "unsubscribe CTMANewsletter" in the subject line. This issue summarizes the results from the 2005 CTMA Symposium held in Tacoma, WA from April 18 - 21. Below are brief descriptions of 51 project ideas developed by the Symposium participants for consideration in the CTMA program. If you are interested in participating in any of the projects, send an e-mail to the NCMS contact person identified with each of the four tracks. Project ideas in each track are not in any particular order. Any questions can be sent to Chuck Ryan, chuckr@ncms.org. CTMA projects must involve new technology development, include >2:1 cost-share from industry, involve cross-service DoD participation, and show industry collaboration. Once projects are approved, all industry participants must also become NCMS government sector members. Further program information is available at http://ctma.ncms.org.
