  • This title presents the general principles of instrumentation processes. It explains the theoretical analysis of physical phenomena used by standard sensors and transducers to transform a physical value into an electrical signal. The pre-processing of these signals through electronic circuits – amplification, signal filtering and analog-to-digital conversion – is then detailed, in order to provide useful basic information. Attention is then given to general complex systems.

  • To facilitate the use of syntactic information in the study of child language acquisition, a coding scheme for Grammatical Relations (GRs) in transcripts of parent-child dialogs has been proposed by Sagae, MacWhinney and Lavie (2004). We discuss the use of current NLP techniques to produce the GRs in this annotation scheme. By using a statistical parser (Charniak, 2000) and memorybased learning tools for classification (Daelemans et al., 2004), we obtain high precision and recall of several GRs. ...

  • Multiple studies have attempted to estimate the cost to major weapon system programs of complying with acquisition-related statutes and regulations. Most have investigated the cost of compliance only at the contractor level, though program offices, the Services, and the Office of the Secretary of Defense would also incur such

  • This paper presents a system capable of automatically acquiring subcategorization frames (SCFs) for French verbs from the analysis of large corpora. We applied the system to a large newspaper corpus (consisting of 10 years of the French newspaper ’Le Monde’) and acquired subcategorization information for 3267 verbs. The system learned 286 SCF types for these verbs. From the analysis of 25 representative verbs, we obtained 0.82 precision, 0.59 recall and 0.69 F-measure. These results are comparable with those reported in recent related work. ...

  • This paper presents an approach for the automatic acquisition of qualia structures for nouns from the Web and thus opens the possibility to explore the impact of qualia structures for natural language processing at a larger scale. The approach builds on earlier work based on the idea of matching specific lexico-syntactic patterns conveying a certain semantic relation on the World Wide Web using standard search engines. In our approach, the qualia elements are actually ranked for each qualia role with respect to some measure. ...

  • The LabVIEW Tutorial contains the information you need to get started with the Laboratory Virtual Instrument Engineering Workbench (LabVIEW) software package. LabVIEW simplifies scientific computation, process control, and test and measurement applications, and you can also use it for a wide variety of other programming applications. This manual gives you an overview of the fundamental concepts of LabVIEW, and includes lessons to teach you what you need to know to build your own virtual instruments (VIs) as quickly as possible. This manual does not explain every LabVIEW feature.

  • Until fairly recently most scientific data-gathering systems and industrial control procedures were based on electromechanical devices such as chart recorders and analogue gauges. The capability to process and analyse data was rather limited (and in some cases error prone) unless one had access to a minicomputer or mainframe. Today, that situation has changed considerably. I am sure that most potential readers of this book will be aware of the profound effect the PC has had on the way in which engineers and scientists are able to approach data-gathering tasks....

  • In this paper we present the implementation of a digital lock-in amplifier (LIA) completely based on Labview with a general-purpose data acquisition board (or a high quality sound card) and a high-gain low-noise amplifier. The signal analysis is processed by the software. We describe some characteristics of the LIA including output voltage vs. frequency and output phase vs. noise. The LIA can be used to measure the small signals, even in presence of broadband noise which is several times greater than the signal itself. Since the signal processing takes place on the computer, ...

  • A probit regression model is estimated in order to analyze how firm age and size affect the likelihood of being a HGF. The analysis confirms that firm age and size affect the probability of a firm becoming any type of HGF. Larger firms are more likely to be HGFs measured in absolute numbers and less likely when HGFs are measured in relative numbers. Firm age has a significant negative impact on the likelihood of being a HGF in almost all regressions, indicating that young firms are more likely to be HGFs irrespective of how HGFs are defined. Thus, new firm...
