Evaluation of Giga-bit Ethernet Instrumentation for SalSA Electronics Readout (GEISER)

An instrumentation prototype for acquiring high-speed transient data from an array of high bandwidth antennas is presented. Multi-kilometer cable runs complicate acquisition of such large bandwidth radio signals from an extensive antenna array. Solutions using analog fiber optic links are being explored, though are very expensive. We propose an inexpensive solution that allows for individual operation of each antenna element, operating at potentially high local self-trigger rates. Digitized data packets are transmitted to the surface via commercially available Giga-bit Ethernet hardware. Events are then reconstructed on a computer farm by sorting the received packets using standard networking gear, eliminating the need for custom, very high-speed trigger hardware. Such a system is completely scalable and leverages the hugh capital investment made by the telecommunications industry. Test results from a demonstration prototype are presented.Comment: 8 pages, to be submitted to NIM

Communication, Affect, & Learning in the Classroom

The purpose of the handbook was to synthesize the first three decades of research in instructional communication into a single volume that could help both researchers and instructors understand the value of communication in the instructional process.Preface1.Teaching As a Communication Process The Instructional Communication Process The Teacher The Content The Instructional Strategy The Student The Feedback/Evaluation The Learning Environment/Instructional Context Kibler’s Model of Instruction The ADDIE Model of Instructional Design2.Communicating With Instructional Objectives Why Some Teachers Resent Objectives The Value of Objectives What Objectives Should Communicate3.Instructional Communication Strategies The Teacher As a Speaker The Teacher As a Moderator The Teacher As a Trainer The Teacher As a Manager The Teacher As a Coordinator & Innovator4.Communication, Affect, and Student Needs Measuring Student Affect Basic Academic Needs of Students Traditional Interpersonal Need Models Outcomes of Meeting Student Needs5.Learning Styles What is Learning Style?

Space processes for extended low-G testing

Results of an investigation of verifying the capabilities of space processes in ground based experiments at low-g periods are presented. Limited time experiments were conducted with the processes. A valid representation of the complete process cycle was achieved at low-g periods ranging from 40 to 390 seconds. A minimum equipment inventory, is defined. A modular equipment design, adopted to assure low cost and high program flexibility, is presented as well as procedures and data established for the synthesis and definition of dedicated and mixed rocket payloads
