Technological survey of tellurium and its compounds

Review includes data on the chemical and physical properties of tellurium, its oxides, and fluorides, pertinent to the process problem of handling fission product tellurium in fluoride form. The technology of tellurium handling in nonaqueous processing of nuclear fuels is also reviewed

\u3cem\u3eLaunching through the Surf\u3c/em\u3e Traveling Exhibit Panel 10: Fiberglassing and Painting a Dory

Panel 10 documents the process of fiberglassing and painting (gelcoating) a new wooden dory. During the spring of 2012, project collaborator Tyrone Marshall photographed Pacific City glasser Jim Allen as he fiberglassed dory number 82, the Rehab.https://digitalcommons.linfield.edu/dory_exhibit/1009/thumbnail.jp

Computational tasks in robotics and factory automation

The design of Manufacturing Planning and Control Systems (MPCSs) — systems that negotiate with Customers and Suppliers to exchange products in return for money in order to generate profit, is discussed.\ud \ud The computational task of MPCS components are systematically specified as a starting point for the development of computational engines, as computer systems and programs, that execute the specified computation. Key issues are the overwhelming complexity and frequently changing application of MPCSs

Advanced Design Concepts for Open Distributed Systems Development

Experience with the engineering of large scale open distributed systems has shown that their design should be specified at several well-defined levels of abstraction, in which each level aims at satisfying specific user, architectural, and implementation needs. Therefore, designers should dispose of a comprehensive design methodology, which allows them to conceive a specification at a certain abstraction level and transform this specification into a conforming specification at a lower abstraction level. The collection of these transformations should abridge the total design trajectory from initial user requirements to final implementation. The authors present and discuss some advanced design concepts that provide a basis for such a design methodolog

What makes industries believe in formal methods

The introduction of formal methods in the design and development departments of an industrial company has far reaching and long lasting consequences. In fact it changes the whole environment of methods, tools and skills that determine the design culture of that company. A decision to replace current design practice by formal methods, therefore, appears a vital one and is not lightly taken. The past has shown that efforts to introduce formal methods in industry has faced a lot of controversy and opposition at various hierarchical levels in companies, resulting in a marginal spread of such methods. This paper revisits the requirements for formal description techniques and identifies some critical success and inhibiting factors associated with the introduction of formal methods in the industrial practice. One of the inhibiting factors is the often encountered lack of appropriateness of the formal model to express and manipulate the design concerns that determine the world of the engineer. This factor motivated our research in the area of architectural and implementation design concepts. The last two sections of this paper report on some results of this research

Advances in architectural concepts to support distributed systems design

This paper presents and discusses some architectural concepts for distributed systems design. These concepts are derived from an analysis of limitations of some currently available standard design languages. We conclude that language design should be based upon the careful consideration of architectural concepts. This paper aims at supporting designers by presenting a methodological design framework in which they can reason about the design and implementation of distributed systems. The paper is also meant for language developers and formalists by presenting a collection of architectural concepts which deserve consideration for formal support
