The aim of the research in progress is to enhance continuously cast billets images software analyzer (based on sulfur prints and template photos) data aquisition and preparation methods. Aquired sulfur prints images and templates photographs were evaluated according to statistical criteria. Raw data aquisition and preparation methods for continuously cast billets analysis software based on sulfur prints and templates photographs were developed in course of work. Conditions of aquiring templates sulfur prints and photographs were also evaluated

Data Aquisition

This study is meant as a warning and an encouragement alike, when it comes to data aquisition, processing and interpretation in micro sized devices. In our study we start with the raw data gained from radial channel flow between two opposing discs with flow from the centre to the edge. Processing these data with certain concepts of Knudsen number, or more general “micro effects” in mind, is shown to be not at all straightforward. Depending on how critically these data are looked upon and how deep the experimental device is analysed very different “results” are gained.

Mining Methods

Data-driven quality evaluation in the stamping process of car body parts is quite promising because dependencies in the process have not yet been sufficiently researched. However, the application of data mining methods for the process in stamping plants would require a large number of sample data sets. Today, acquiring these data represents a major challenge, because the necessary data are inadequately measured, recorded or stored. Thus, the preconditions for the sample data acquisition must first be created before being able to investigate any correlations. In addition, the process conditions change over time due to wear mechanisms. Therefore, the results do not remain valid and a constant data acquisition is required. In this publication, the current situation in stamping plants regarding the process robustness will be first discussed and the need for data-driven methods will be shown. Subsequently, the state of technology regarding the possibility of collecting the sample data sets for quality analysis in producing car body parts will be researched. At the end of this work, an overview will be provided concerning how this data collection was implemented at BMW as well as what kind of potential can be expected.

Deuteron Spin

The new powerful VME–based data acquisition (DAQ) system has been designed for the Deuteron Spin Structure setup [1] placed at the Nuclotron Internal Target Station [2]. The DAQ system is built using the netgraph–based data acquisition and processing framework ngdp [3, 4]. The software dealing with VME hardware is a set of netgraph nodes in the form of the loadable kernel modules. The specific for current implementation nodes are described, while specific software utilities for the user context are the following. The b2r (binary–to–ROOT) server converts raw data into per trigger and per accelerator spill representations, which are based on C++ classes derived from the ROOT framework [5] ones. This approach allows us to generalize the code for histograms filling and polarization calculations. The b2r optionally stores ROOT events as ROOT TTree in file(s) on HDD, and supports the design of some express offine. The histGUI software module provides an interactive online access for human operator to histograms filled by the r2h (ROOT–to–histograms) server, which obtains the ROOT event representations from b2r. The r2h supports the calculation and histograming of runtime configurable variables as well as raw data variables, and optionally stores ROOT histograms in file(s) on HDD. Since the spin studies at the Nuclotron require fast and precise determination of the deuteron and proton beam polarization, the polarization calculator software module is introduced. This calculator based on runtime configurable r2h code allows us to compute polarization values online and integrate them into the Web–based scheme of representation and control of the polarimeters [6, 7].

Abstract. The Millstone Hill Incoherent Scatter Data Acquisition System (MIDAS) is based on an abstract model of an incoherent scatter radar. This model is implemented in a hierarchical software system, which serves to isolate hardware and low-level software implementation details from higher levels of the system. Inherent in this is the idea that implementation details can easily be changed in response to technological advances. MIDAS is an evolutionary system, and the MIDAS hardware has, in fact, evolved while the basic software model has remained unchanged. From the earliest days of MIDAS, it was realized that some functions implemented in specialized hardware might eventually be implemented by software in a general-purpose computer. MIDAS-W is the realization of this concept. The core component of MIDAS-W is a Sun Microsystems UltraSparc 10 workstation equipped with an Ultrarad 1280 PCI bus analog to digital (A/D) converter board. In the current implementation, a 2.25 MHz intermediate frequency (IF) is bandpass sampled at 1 µs intervals and these samples are multicast over a high-speed Ethernet which serves as a raw data bus. A second workstation receives the samples, converts them to filtered, decimated, complex baseband samples and computes the lag-profile matrix of the decimated samples. Overall performance is approximately ten times better than the previous MIDAS system, which utilizes a custom digital filtering module and array processor based correlator. A major advantage of MIDAS-W is its flexibility. A portable, single-workstation data acquisition system can be implemented by moving the software receiver and correlator programs to the workstation with the A/D converter. When the data samples are multicast, additional data processing systems, for example for raw data recording, can be implemented simply by adding another workstation with suitable software to the high-speed network. Testing of new data processing software is also greatly simplified, because a workstation with the new software can be added to the network without impacting the production system. MIDAS-W has been operated in parallel with the existing MIDAS-1 system to verify that incoherent scatter measurements by the two systems agree. MIDAS-W has also been used in a high-bandwidth mode to collect data on the November, 1999, Leonid meteor shower.Key words: Electromagnetics (instruments and techniques; signal processing and adaptive antennas) – Ionosphere (instruments and techniques)
