ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, California / Network-centric data acquisition and telemetry systems continue to gain momentum and adoption. However, inherent non-deterministic network delays hinder these systems’ suitability for use where high-accuracy timing information is required. The emerging IEEE 1588 standard for time distribution offers the potential for real-time data acquisition system development using cost-effective, standards-based network technologies such as Ethernet and IP multicast. This paper discusses the challenges, realities, lessons, and triumphs experienced using IEEE 1588 in the development and implementation of such a large-scale network-centric data acquisition and telemetry system. IEEE 1588 clears a major hurdle in moving the network-centric buzz from theory to realization.

International Telemetering Conference Proceedings / November 04-07, 1991 / Riviera Hotel and Convention Center, Las Vegas, Nevada / During the requirements definition process for a new telemetry and data acquisition product, Veda Systems engineers had the opportunity to examine the requirements for the ideal bus architecture to support future needs. Design goals and requirements were solicited from major users in flight test, space ground station data monitoring and command applications, and C41, as well as Veda’s own engineers. The process resulted in a bus architecture design which could potentially set the standard for the next generation of telemetry and data acquisition systems. This paper outlines the design goals selected and the thought process that yielded the goals in an attempt to promote advancement of current bus design approaches and increased availability of standard architectures and operating environments.

International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / One of the primary tasks of a telemetry system is able to acquire multichannel impulse parameters. Some of the defects of old methods such as, low availability of equipment, channels and data never suit the needs of the requirements for the modern telemetry system, it would be more small, rapid, flexible and low cost. This paper gives a new method, it raises the availability mentioned above and forms an integrated telemetry system with the acquisition of other parameters, so it satisfies the requirements for modern telemetry system.

The evolution of the concept of language interference and how it has been instructionally applied to Spanish English Chicano children in the United States was the central thesis of this work. The study attempted to answer the following questions: (1) What does language interference mean? (2) How is it used? and (3) Why is it used in teaching English to Spanish speaking Chicano students in the United States? The study revealed that: (1) Two implicit paradigms, the languages as habit formation and the languages in contact, explained the meaning of language interference. (2) The guiding assumption operating under the language as habit formation paradigm had never been examined; thus, the wide acceptance of the habit formation theory, which defined interference as differences between two languages causing difficulty and interference. (3) The unexamined assumption in the habit formation paradigm when examined with twelve Spanish English bilingual children in grades 2, 4, and 6 was not valid; thus its instruction practices regarding language learning and language teaching are not valid. (4) Given the new knowledge about language learning and teaching (applied sociolinguistics and applied psycholinguistics), the definition of language interference had to be expanded and redefined; thus a new paradigm emerged--languages in communicative use--but its unexamined assumptions need to be examined now. (5) The wide acceptance of the habit formation definition of language interference was due to racism, prejudice, and elitism in intellectual guise. (6) Given that the habit formation definition of language interference is valid, then changing teachers' perceptions, attitudes, and understanding about language learning and teaching, and bilingualism would necessitate a demythification process. This study was a descriptive, theoretical, and epistemological examination of a phenomena that occurs when two languages are used to communicate. How reality is described depends on one's governing gaze, operating assumptions (both implicit and explicit), logic of reasoning, and theory building. If a theory is built on an unexamined assumption, i.e., has never been tested with reality, then its perpetuation builds an illusion, a myth that people try to make real. The construction and description of reality are challenging tasks in any field of study.

Peace Corps Fellows award for commitment to the community / What are Iskashitaa Refugee Harvesting Network’s roles and objectives in teaching English as a Second Language to adult refugees in the Tucson community? How can we create a classroom environment that builds their language acquisition while promoting self-sufficiency? To inquire into these questions, interviews were conducted with adult refugee students who attend the classes, anecdotal records were kept of the ESL teachers’ weekly reflections and classroom observations were performed. Iskashitaa’s ESL classes should provide a space for English language acquisition, assisting in the acculturation process through introducing material that is based on life-skills, with the teachers serving as a cultural broker, advocate and friend and finally, introducing the adult refugees to the community through volunteer activities with Iskashitaa. There is a need for more inquiry and discussion about the pre-literate refugee population, especially in effective teaching strategies, curriculum ideas and a better understanding of literacy practices within the home. These are matters that merit a larger discussion by people who work in education and with refugees, as feedback would be beneficial from all who work with refugees and can recommend what they have observed, experienced and envision to help in the language acquisition, self-sufficiency and acculturation process for refugees.
