The existence of the Working Group for data-processing in Phytosociology spans about six years, 1969-1975. 'Its activities are summarized and a series of papers to appear in Vegetatio, presenting results of various numerical treatments, mainly of salt marsh vegetation, is introduced. A survey is given of seven releve selections to which treatments were applied. Five main fields of activities are discussed: systematical data-processing, rearrangement of phytosociological tables, development of classification and ordination techniques, numerical syntaxonomy, and theoretical phytosociology. The establishment of the Working Group for Theoretical Phytosociology and its first symposium on theoretical aspects is announced. © 1973 Dr. W. Junk b.v. - Publishers.

The number of software vulnerabilities is increasing year by year. In the era of big data, data-processing software with many users is more concerned by hackers. It is essential to improve the efficiency of discovering vulnerabilities in data-processing software. We noticed that in the process of discovering vulnerabilities, some problems of existing technology such as fuzzing, symbolic execution, and taint analysis have more or fewer relationships with data-processing functions. In fuzzing, there are two types of sanity checks toward the target program: NCC (Non-critical check) and CC (critical check). It is usually challenging to bypass such a sanity check, which leads to low code coverage during fuzzing. In symbolic execution, the constraint solver still has the problem of trying to deal with the constraints of complex algorithms. In taint analysis, the problem of over-taint and under-taint is always the key to affect the accuracy of the results. Therefore, to solve the above problems, it is necessary to identify the data-processing function. Based on identifying data-processing functions, we could identify those sanity checks, ease the solution of complex constraints, and understand the way of taints propagation to assist in software vulnerability discovery and analysis. This paper proposed a method called DPFI(data-processing function identification) for identifying data-processing functions with deep neural networks. We collected 37000 functions from GitHub and implemented the method on the data set with several neural networks, among which the performance of CNN achieved best and F-1-score was 0.90. We then applied the trained model on CGC(cyber grand challenge) data and real softwares for testing. For CGC, we got 448 functions in 20 programs, in which 35 were identified as data-processing functions. For real softwares, such as FFmpeg, 7zip, jpeg, the precision rate all reached 0.90 and F-1-score was above 0.87.

ELEMENTS FOR A SYSTEM OF data-processing IN PHYTOSOCIOLOGY AND ECOLOGY

VEGETATIO 1979年第2期40卷 115-123页

作者： DAVID, P LEPART, J ROMANE, F CNRS ECOTHEQUE MEDITERRANEENNE F-34033 MONTPELLIER FRANCE

An organization for data-processing in phytosociology and plant ecology is described. A good preparation by means of standard sheets for collecting and codifying information from the field is emphasized. The arrangement and the logical sequence of the different methods of data analysis (ecological profiles, factor analysis, etc.) which allows the study of the relations between environmental and floristical variables, in a quick and efficient way are presented. Cooperation with the Ecotheque mediterraneene at Montpellier is both necessary and fruitful. One example is presented using the selection of 58 releves of salt marsh vegetation retained by the Working Group for data-processing of the International Society for Vegetation Science.

Modern laboratory management software must be able to produce pathological reports for all specimens referred for diagnostic analysis, and must also be able to ensure improved quality for each step of the diagnostic process. Indices of diagnostic quality useful for staff members should be made available. The management software should enable user-friendly analysis and comparison in order to choose what kind of changes should to be applied for appropriate implementation of Quality Assurance procedures. This methodology is especially useful for Papsmears.

SYSTEM FOR CODING PLANT SPECIES FOR data-processing IN PHYTOSOCIOLOGY

引用

VEGETATIO 1976年第1期33卷 23-32页

作者： PIGNATTI, S UNIV TRIESTE IST & ORTO BOT I-34100 TRIESTE ITALY

A system for coding plant species is described. The system is in use in the project data-processing in phytosociology. The code consists of 7 digits, 4 for the genus and 3 for the species. The genus code is derived from Dalla Torre and Harms, with ad hoc numbers for Pteridophyta, Bryophyta and Lichenes. Species codes are established according to Flora Europaea, Volumes I-III, and for species not treated there according to an alphabetical list of species based on SW European floras, completed with ad hoc data for other parts of Europe. About 9000 species names have been coded at Trieste [Italy]. The coding system is compared with the systems of Ehrendorfer, Flora Europaea, alphabetic systems and Gould''s international plant index. Problems of nomenclatural changes and species concepts and their bearing on the code are discussed.

6th IFAC Workshop on Distributed Estimation and Control in Networked Systems (NECSYS)

作者： van Horssen, E. P. Antunes, D. Heemels, W. P. M. H. Eindhoven Univ Technol Control Syst Technol Grp POB 513 NL-5600 MB Eindhoven Netherlands

Many control applications, such as vision-based control, require data-processing methods to distill sensor information. This data-processing introduces several undesired effects in the control loop, such as delays, the probability of not acquiring information, and measurement inaccuracies. Often, these effects obey a trade-off. For example, the probability of acquiring control-relevant information, related to the probability of data-loss, is typically higher if a larger delay is allowed. While a single processing method with a reasonable trade-off is typically selected, we propose instead a solution to switch between data-processing methods with different delays and corresponding data-loss probabilities. We prove that the proposed method achieves a better LQG-type performance when compared to the individual methods. A simulation considering a second-order system illustrates the advantages of the proposed method. (C) 2016, IFAC (International Federation of Automatic Control) Hosting Elsevier Ltd.
