The Computer Augmented Field Data Recording System-CAFDRS-is a unique combination of a standard seismic digital field recording system and a mini-computer system, specifically conceived to provide a major advance in monitoring and analysing data as it is being acquired in the field. On-line operations include capability to: composite, vertically stack, correlate VIBROSEIS data, control the recording operation and make power spectrum analysis. Off-line operations include the ability to play back data at a later time, and perform most of these same operations, plus, produce a normal-move-out corrected common-depth-point stacked section. Experience with CAFDRS in the field demonstrates both the versatility of the concept and the effectiveness of being able to analyse data "on the spot" particularly when using the VIBROSEIS technique. Noise, source array and geophone analyses are made "on- line" as the experimental program is conducted. By using the frequency analysis program to obtain power spectra, the optimum vibrator sweep can be established for the particular area.The 16 bit word base used in the mini-computer system preserves the 76db of dynamic range of the data acquired by the XDS-1010 or the DFS III, two of the standard field systems now used in CAFDRS. The dynamic range of the compositing and correlating operations accomplished with the SPC-16 mini-computers compares favorably with that obtained in a large scale data processing centre.The noise editing feature included in the double precision floating point compositing program reduces the deteriorating effect that large bursts of random noise have on most composited data. Composited data correlated in the field compares almost exactly with the same data correlated in the data centre. The NMO/CDP raw stacks produced in the field compare favorably with ones produced in the data centre.Note: VIBROSEIS is a trademark of the Continental Oil Company and DINOSEIS is a trademark of the Atlantic Richfield Oil Company.

Meaningful Data

AbstractCommingled and fragmentary remains are found in numerous contexts worldwide. These assemblages typically require large scale, long term study to fully extract and contextualize meaningful data. However, when uncovered in CRM and foreign settings where remains cannot leave their country of origin, there is a need for quick, reliable data collection. Presented here is a recording system for use in field- and research-based laboratory settings. Utilizing visual forms and a minimal set of observations for skeletal elements from the cranium to the foot, the database facilitates data collection of fragment identification, age at death and sex estimation, dental observations, trauma recording, and taphonomic observations. A data dictionary is also provided, with definitions and value lists used in the database itself. The database has been used in field labs throughout the old world and by numerous researchers who have modified it to meet their own research needs. By presenting a minimal standard of data in a highly adaptable database, the recording system described here provides consistent baseline data in a user-friendly, quick-access format

Remote Data

This paper focuses on development of remote data monitoring and recording system in industries. Now a days we are using many Networked embedded systems for monitoring and control the home or industrial devices.These low cost devices are capable of reporting and receiving information in just the same way that computers on a network. The advent of Internet communication standard, TCP/IP, offers significant potential in terms of remote monitoring and management of construction sites using embedded systems. In this paper the design method of low cost system of remote data monitoring, and recording is designed based on ARM. For this a small HTTP SERVER is built in LPC2148 and it is connected with the remote monitoring terminal through Ethernet. The data can be stored in the SD Card via SPI interface. At the same time, for the sake of the versatility, the FAT file system is built in the SD Card. So, an Ethernet-enabled remote data monitoring system with the ability of data recording is built. This design is having advantage of cost-effective, easily realized, stable and reliable transmission. It can be connected to the INTERNET or LAN through TCP/IP protocol. FreeRTOS is used as an operating system running on ARM processor, an industrial grade RTOS for hard time applications. By this design the data is sent without a PC and system favour’s large scale data acquisition system.

Very Long Baseline Array

The Very Long Baseline Array (VLBA) will be the world's first large-scale dedicated VLBI facility. It is planned as a multipurpose instrument, supporting continuum, spectroscopic, astrometric/geodetic, multi-frequency, bandwidth synthesis, polarization, and pulsar measurements – with a variety of bandwidths, sampling rates, quantization schemes, and multi-band modes. The Array will consist of ten new 25-m precision antennas, in an optimized geographical configuration. Extremely low-noise receivers will support observations with dual polarization in nine frequency bands from 330 MHz to 43 GHz, including almost all conventional VLBI bands. A wideband, high-density recording system will allow unattended operation at a sustained data rate of 128 Mbit/s for 24 hours, and peak rates up to 512 Mbit/s. The VLBA correlator, planned as a 20-station system to support processing of all observations involving the Array, will be by far the largest ever built for VLBI. The Array will be operated remotely, from a new operations and data-reduction center to be built in Socorro, NM.

Spectrum Radio

The quasar 3C216 has the distinction of being classified as a blazar as well as a compact steep-spectrum radio source (Akujor et al, 1993). It has a grossly mis-aligned large-scale radio structure. Previous VLBI images include those of the core region (Barthel et al 1988; Venturi et al 1993) with 1 mas resolution, and the sub-kpc scale core-jet with resolution ca. 25 mas (Fejes et al, 1992; Akujor et al, 1993). In order to investigate the connection between these structures seen on different scales, we have made a 1.6 GHz observation of the core-jet region with a “World Array” VLBI network. This consisted of 20 antennas, at Effelsberg (Germany), Jodrell “Lovell” (UK), Westerbork (Netherlands), Medicina and Noto (Italy), Onsala-26m (Sweden), Torun-15m (Poland), Simeiz (Ukraine), Bear Lakes (Russia), Seshan (China), Hartebeesthoek (S. Africa), Green Bank-43m, VLA and the VLBA antennas at HN, NL, PT, KP, LA, BR, OV (USA). The observations were made on 18 November, 1992, using the Mk2 recording system, and these were amongst the last to be correlated using the JPL-Caltech Block2 processor. The NRAO AIPS package was used for the data analysis.

Period Comet

AbstractUnusual short-period comet 29P/Schwassmann-Wachmann 1 inspired many observers to explain its unpredictable outbursts. In this paper large scale structures and features from the inner part of the coma in time periods around outbursts are studied. CCD images were taken at Whipple Observatory, Mt. Hopkins, in 1989 and at Astronomical Observatory, Modra, from 1995 to 1998. Photographic plates of the comet were taken at Harvard College Observatory, Oak Ridge, from 1974 to 1982. The latter were digitized at first to apply the same techniques of image processing for optimizing the visibility of features in the coma during outbursts. Outbursts and coma structures show various shapes.
