This paper presents a virtual foundry environment that can be accessed over Internet by design and manufacturing engineers, for preliminary process planning of cast components. The plans are automatically generated by case based reasoning using the nearest neighbor algorithm. An interactive facility is also provided for handling entirely new cases that do not have matching cases in the database...

The production volume of metals and their alloys, taking into account the current demand for materials containing steel, cast iron, non-ferrous will continue to increase in near future [...]

B. Gal, K. Granat, D. Nowak, Wroclaw University of Technology, Department of Foundry Engineering, Plastics and Automation and Automation, Wrocław, Poland The presented basic research was aimed at determining a correlation between compaction degree of moulding sand and its permittivity εr at 2,45·10 9 s-1. The measurement results make a basis for mathematical description of a multilayer technolo...

A lot sizing and scheduling problem from a foundry is considered in which key materials are produced and then transformed into many products on a single machine. A mixed integer programming (MIP) model is developed, taking into account sequence-dependent setup costs and times, and then adapted for rolling horizon use. A relax-and-fix (RF) solution heuristic is proposed and computationally teste...

This paper discusses the possible introduction of hidden reliability defects during CMOS foundry fabrication processes that may lead to accelerated wearout of the devices. These hidden defects or hardware Trojans can be created by deviation from foundry design rules and processing parameters. The Trojans are produced by exploiting time-based wearing mechanisms (HCI, NBTI, TDDB and EM) and/or co...

M. Łucarz, AGH University of Science of Technology, Engineering of Faculty Foundry, Kraków, Poland The paper presents the results of the research on the used moulding sands subjected to mechanical and thermal reclamation at different stages of the process in the foundry. The research on thermal treatment was carried out in an experimental thermal reclamation appliance. The effects of the proces...

The Open Biomedical Ontology (OBO) Foundry initiative is a collaborative effort for developing interoperable, science-based ontologies. OBO uses the Basic Formal Ontology (BFO) as its upper ontology. Ontologies developed for OBO use include some that have been ratified, and others holding the status of candidate. There are no formal, principled criteria that a candidate ontology must meet for r...

this study deals with employing foundry sand (fs) as new low cost iron source in heterogeneousphoto-fenton process for the degradation of herbicide isoproturon (ipu) in aqueous solution. thecharacterization of the fs by eds confirmed presence of iron (23%) required for photo-fenton andsimultaneously confirmed absence of any heavy metals which may be susceptible to leaching. the photo-fenton eff...
