whitepaper Ethernet Network-Based DAQ and Smart Sensors for the OPERA Long-Baseline Neutrino Experiment2008-03-18 AGILENT
  This paper proposes a data acquisition scheme for the OPERA long-baseline neutrino experiment based exclusively on Ethernet. The expected data rate allows the use of an Ethernet capable device close to the sensor. The basic idea is to build a distributed acquisition system on Ethernet, made of about 1000 nodes of 64 channel front-end modules. Each node will be controlled and readout by an embedded Ethernet chip and will be therefore transparently visible on the network. These modules will be directly controlled by the event building computers and will be able to execute a set of embedded functions for slow control monitoring and data readout. The paper presents a first prototype of Ethernet capable front-end module with high speed ADC and TDC capabilities.

whitepaper The Forrester Wave: Information-as-a-Service, Q1 20082008-01-23 Forrester Research
  Forrester evaluated leading enterprise Information-as-a-Service (IaaS) vendors across 94 criteria and found that BEA Systems, IBM, Oracle, and Red Hat have established leadership positions, thanks to their IaaS capabilities, breadth of focus, and strong product and corporate strategy. BEA Systems and Oracle were the only vendors that topped all IaaS use cases. Ipedo, Composite Software, Microsoft, and Endeca Technologies are Strong Performers because their features and functionality are not sufficiently comprehensive to excel at all IaaS use cases, but Microsoft is among the Leaders in two selective use cases. Xcalia still has work ahead to build stronger features and functionality, but for now, it lags behind the Leaders in some key IaaS capabilities.

whitepaper Conceptual Model Based Normalization of XML2008-01-01 Univerzita Karlova v Praze
  As the popularity of XML as a format for data representation grows the need for storing XML data in an effective way grows as well. Recent research has provided with effective solutions based on storing XML data into relational databases and with new technologies based on storing XML data in the native form. However, design of XML databases has not been studied sufficiently yet. This paper supposes a set of XML schemes that describe XML representation of the data in several types of XML documents. They show that they can not usually store the data directly in this representation because it can contain redundancies. To design an optimal database schema they therefore need to locate these redundancies and eliminate them.

whitepaper Data Acquisition From Cell Phone Using Logical Approach2007-12-01 World Academy of Science, Engineering and Technology
  Cell phone forensics to acquire and analyze data in the cellular phone is nowadays being used in a national investigation organization and a private company. In order to collect cellular phone flash memory data, they have two methods. Firstly, it is a logical method which acquires files and directories from the file system of the cell phone flash memory. Secondly, they can get all data from bit-by-bit copy of entire physical memory using a low level access method. This paper describes a forensic tool to acquire cell phone flash memory data using a logical level approach. By the tool, they can get EFS file system and peek memory data with an arbitrary region from Korea CDMA cell phone.

whitepaper Preliminary Thoughts on the Data Acquisition for the Next Generation of Silicon Tracking Systems2007-12-01 Indian Academy of Sciences
  Preliminary thoughts about the data acquisition system to be developed for the next generation of large area silicon tracker are presented in this paper. This paper describes the set of data delivered by these tracking systems, and the various stages of processing and data flow transmission from the front-end chip sitting on the detector to the latest stage in the data processing. How to best profit from the status of the art technologies is a major goal.   
whitepaper Orchid: Integrating Schema Mapping and ETL2007-11-17 IBM
  This paper describes Orchid, a system that converts declarative mapping specifications into data flow specifications (ETL jobs) and vice versa. Orchid provides an abstract operator model that serves as a common model for both transformation paradigms; both mappings and ETL jobs are transformed into instances of this common model. As an additional benefit, instances of this common model can be optimized and deployed into multiple target environments. Orchid is being deployed in FastTrack, a data transformation toolkit in IBM Information Server.   
whitepaper Deciding the Physical Implementation of ETL Workflows2007-11-09 Association for Computing Machinery
  This paper deals with the problem of determining the best possible physical implementation of an ETL workflow, given its logical-level description and an appropriate cost model as inputs. The paper formulates the problem as a state-space problem and provides a suitable solution for this task. The paper further extends this technique by intentionally introducing sorter activities in the workflow in order to search for alternative physical implementations with lower cost. The paper experimentally assesses the method based on a principled organization of test suites.

whitepaper Bust a Move with Your SSIS - Passing Package Variables2007-11-06 Global Knowledge
  Integration Services (SSIS), the next generation of the Extract, Transport, and Load (ETL) feature included with Microsoft SQL Server 2005 has befuddled Database Administrators. SSIS includes many new capabilities bundled with a Visual Studio front end. This paper explores the creation of sample development data featuring the use of the most basic features in this new interface.

whitepaper Hard Real Time Quick EXAFS Data Acquisition With All Open Source Software on a Commodity Personal Computer2007-10-01 Brookhaven National Laboratory
  This paper describes here the data acquisition subsystem of the Quick EXAFS (QEXAFS) experiment at the National Synchrotron Light Source of Brookhaven National Laboratory. For ease of future growth and flexibility, almost all software components are open source with very active maintainers. Among them, Linux running on x86 desktop computer, RTAI for real-time response, COMEDI driver for the data acquisition hardware, Qt and PyQt for graphical user interface, PyQwt for plotting, and Python for scripting. The signal (A/D) and energy-reading (IK220 encoder) devices in the PCI computer are also EPICS enabled. The control system scans the monochromator energy through a networked EPICS motor. With the real-time kernel, the system is capable of deterministic data-sampling period of tens of micro-seconds with typical timing-jitter of several micro-seconds.

whitepaper Low Cost Data Acquisition Setup for Electrical Machines Laboratory2007-09-05 Politehnica University of Timisoara
  This purpose of this experimental setup in association with the appropriate LabVIEW/Matlab software presented in this paper is especially destinated to be used for testing of electrical machines. This software is useful for the Electrical Machines Laboratory in University, and also for industrial use, in Electrical Machines factory. The simulation feature which is included in the main LabVIEW program is also useful for the student's practices. The facilities in the simulation mode are the same as in acquisition mode. There are the possibilities to continuous develop this software, to be adapted to various transducer boards and to calculate and display various parameters.
