A new method for increasing LDR in deep drawing is application of anti-lock braking system (ABS) on blank holder. In this method, instead of applying a constant force on blank and control the metal flow, the ABS system holds and releases the blank several times (20 to 50 times) which results increasing LDR. This study investigates the effect of different parameters of ABS on improving the condi...

The paper proposes multi-operation blank localization to fit final product geometries into near net shape blanks. Groups of machining features are located subject tolerance intervals on their relative positions and a lower bound the allowance which accommodates for uncertainties measurement machining. error, i.e., deviation resulting dimensions from center is minimized. problem formulated as co...

Generators for synthetic RDF datasets are very important for testing and benchmarking various semantic data management tasks (e.g. querying, storage, update, compare, integrate). However, the current generators do not support sufficiently (or totally ignore) blank node connectivity issues. Blank nodes are used for various purposes (e.g. for describing complex attributes), and a significant perc...

In various domains and cases, we observe the creation and usage of information elements which are unnamed. Such elements do not have a name, or may have a name that is not externally referable (usually meaningless and not persistent over time). This paper discusses why we will never ‘escape’ from the problem of having to construct mappings between such unnamed elements in information systems. S...

Finite element simulation of stretch flanging process was carried out in order to investigate the effect of process parameters on maximum thinning (%) in stretch flanging process. Influences of initial flange length, punch die clearance, width of sheet metal blank and blank holding force were investigated on maximum thinning (%). Finite element simulation was done using FEM software package ABA...

The effect of aqueous solution of citric acid (CA) on the lipid stability of the European catfish (Silurus glanis) fillets during frozen storage (up to 6 months) was investigated. Rancidity development was measured by several biochemical indices (free fatty acids, peroxides and TBA) and complemented by the measurement of expressible moisture and sensory evaluation (flesh odor, consistency and f...
