This paper describes the current state-of-the-art in autonomous land vehicle (ALV) systems and technology. Application of ALV systems span relatively structured domains in mining, cargo handling, and agriculture, through potential application in very unstructured tasks such as bush fire fighting, forestry, and defence. In this paper, four key functional ALV technology areas are identified and discussed. These are mobility, localization, navigation, and planning. The essential conclusion of this paper is that the necessary sensors, algorithms, and methods already exist to develop, demonstrate, and commercialize ALVs in many applications.

With the development of vehicle maintenance and repair training teaching or training, how to use of equipment and instruments reasonably, improving teaching efficiency and effectiveness become important for the professional educators. In order to reduce the loss of training equipment, improve the quality of teaching and training, the actual fusion technology has become a research direction. Nakedness fusion technology is the virtual simulation and physical teaching organic combination, provides a good reference for the teaching and training. How to develop and use the actual fusion technology is emphatically expounded in this paper.

This paper evaluates four of the most commonly used, freely available, state-of-the-art parsers on a standard benchmark as well as with respect to a set of data relevant for measuring text cohesion, as one example of a learning technology application that requires fast and accurate syntactic parsing. We outline advantages and disadvantages of existing technologies and make recommendations. Our performance report uses traditional measures based on a gold standard as well as novel dimensions for parsing evaluation. To our knowledge, this is the first attempt to evaluate parsers across genres and grade levels for the implementation in learning technology using both gold standard and directed evaluation methods.

Blockchain technology provides secure, reliable and transparent solutions to different challenges arising from the growing need for connectivity presented nowadays. Recent developments in industrial processes sets fertile ground for the application of this technology. Aiming to understand the state of the art of blockchain technology application in the manufacturing industry, this study presents an investigation of relevant publications on the subject, including also bibliometric and systemic analyzes. 30 articles of major relevance were selected from a portfolio of 1432 publications, presented between 2015 and 2019. Thus, it was possible to identify research trends and opportunities.

Various authors have emphasized the spatial information resident in an electron micrograph taken with adequately coherent radiation. In view of the completion of at least one such instrument, this opportunity is taken to summarize the state of the art of processing such micrographs. We use the usual symbols for the aberration coefficients, and supplement these with £ and 6 for the transverse coherence length and the fractional energy spread respectively. He also assume a weak, biologically interesting sample, with principal interest lying in the molecular skeleton remaining after obvious hydrogen loss and other radiation damage has occurred.

In a study of the properties of a Ta-Au metallization system for thin film technology application, the interdiffusion between Ta(bcc)-Au, βTa-Au and Ta2M-Au films was studied. Considered here is a discussion of the use of the transmission electron microscope(TEM) in the identification of phases formed and characterization of the film microstructures before and after annealing.The films were deposited by sputtering onto silicon wafers with 5000 Å of thermally grown oxide. The film thicknesses were 2000 Å of Ta and 2000 Å of Au. Samples for TEM observation were prepared by ultrasonically cutting 3mm disks from the wafers. The disks were first chemically etched from the silicon side using a HNO3 :HF(19:5) solution followed by ion milling to perforation of the Au side.

Over the past few years it has become apparent in our multi-user facility that the computer system and software supplied in 1985 with our CAMECA CAMEBAX-MICRO electron microprobe analyzer has the greatest potential for improvement and updating of any component of the instrument. While the standard CAMECA software running on a DEC PDP-11/23+ computer under the RSX-11M operating system can perform almost any task required of the instrument, the commands are not always intuitive and can be difficult to remember for the casual user (of which our laboratory has many). Given the widespread and growing use of other microcomputers (such as PC’s and Macintoshes) by users of the microprobe, the PDP has become the “oddball” and has also fallen behind the state-of-the-art in terms of processing speed and disk storage capabilities. Upgrade paths within products available from DEC are considered to be too expensive for the benefits received. After using a Macintosh for other tasks in the laboratory, such as instrument use and billing records, word processing, and graphics display, its unique and “friendly” user interface suggested an easier-to-use system for computer control of the electron microprobe automation. Specifically a Macintosh IIx was chosen for its capacity for third-party add-on cards used in instrument control.
