Industrial Robots are complex systems with hard real time, high safety, reliability and availability requirements. Robot Controllers are part of these systems and they are complex hard real time computers, which control a robot’s mechanical parts. To be useful, Robot Controllers must be programmable by end customers. This is typically done through a domain and vendor specific programming langua...

The bid valuation and construction problem for carriers facing combinatorial auctions for the procurement of freight transportation contracts is very difficult and involves the computation of a number of NP-hard sub problems. In this paper we examine computationally tractable approximation methods for estimating these values and constructing bids. The benefit of our approximation method is that...

During the long-term operation, mallets of the forging hammers are exposed to thermal fatigue due to the cyclic temperature changes and impact loads. Taking into account very high price, and a risk of buying frequently the new parts, the necessity of their reparation becomes obvious. The forging hammer mallet (Figure 1), is primarily exposed to the impact compressive loads, and partially also t...
