One of the main challenges introducing Augmented Reality technology into industrial applications is fast, reliable, low-cost authoring of animated AR content of product data created in 3D CAD systems. In this paper we present a product data information pipeline from industry used commercial CAD systems to a augmented reality system. The pipeline utilizes ISO 10303 (STEP) data protocol.

Currently, companies face the unprecedented challenges of the global marketplace, collaborative environments and the entire product lifecycle. There are new requirements for product representations, including: platform/application independence, support for the product lifecycle, rapidly sharing information between geographically distributed applications and users, and protection of commercial s...

In this paper the principles and contents of a new product characteristics driven improvement methodology for embedded systems and product development (PROFES) is introduced. The paper includes also experiences of application of the methodology in practice. The methodology was recently developed in an ESPRIT Project called PROFES (PROduct Focused improvement of Embedded Software processes). The...

this study investigated the effect of rumex sc (commercial product which includes of saccharomyces cervisiae, saponin and essential oils) on rumen fermentation, blood glucose, urea, milk yield and milk composition. animals were offered a basal diet containing alfalfa hay (15.5%), corn silage (24%), beet pulp (7%) and concentrate (53.5%). additionally, rumex sc was included in the experimental d...

Creating and maintaining customer loyalty are strategic requirements for modern business. In the current competitive context, product quality, and brand experience are crucial in building and maintaining customer loyalty. Consumer loyalty, which may be classified into cognitive loyalty and affective loyalty, is related to customers' quality perception. Cue utilization theory distinguishes two d...

This paper estimates a dynamic model of product repositioning in di¤erentiated product markets using data from the broadcast radio industry. The feasibility of repositioning can play an important role in determining the medium and long-run e¤ects of demand shocks, mergers and many kinds of policy intervention. The paper extends techniques for estimating dynamic oligopoly models to a setting wit...

OBJECTIVES To find evidence, either corroborating or refuting, for many persisting beliefs regarding the feasibility of carrying out surgical randomised controlled trials with a placebo arm, with emphasis on the challenges related to recruitment, funding, anaesthesia or blinding. DESIGN Systematic review. DATA SOURCES AND STUDY SELECTION The analysis involved studies published between 1959 ...

This paper is devoted to simulate the arc movement in the quenching chamber of the low-voltage circuit breaker. Based on a group of governing equations, a three-dimensional (3-D) arc model is built and solved by a modified commercial code. According to the simulated results, some phenomena such as a ‘bulge’ in front of the arc column, a tail in the rear of the arc column, arc shrinkage near the...

Discrete groups of isometries provide a rich class of groups for detailed study in an undergraduate course in abstract algebra. After developing some geometric tools, we illustrate several important ideas from group theory via symmetry groups. In particular, we consider conjugation, homomorphisms, normal and nonnormal subgroups, generators and relations, quotient groups and direct and semidirec...
