For example, Bhattacharyya et al. [6] experimentally measured the roll forming loads with different material, thickness and bent angle conditions in order to compare the results with theoretical forming loads calculated with a semi-empirical model.
Lindgren [7] and Larrañaga et al. [8] experimentally measured roll forming forces and torques with different materials in order to validate a roll forming finite element model.
And more recently, Saenz de Argandoña et al. analysed the effect of the roll forming gap in the final quality of the profile and in the forming forces [9].
Acknowledgements The work presented in this paper has been carried out in cooperation with FAGOR ARRASATE Scoop and ORTIC AB within the frame of the EUROSTARS Project “FUTROLL: Development of accurate 3D roll forming technology and machine to manufacture profiles for the automotive industry” (Project number CIIP-20122007) and with the financial support of the Spanish agency CDTI Centro para el Desarrollo Tecnológico Industrial.

Foam glass has also been produced from cathode ray tubes by [8], [9], [10]; Pâmela Andréa Mantey dos Santos et al. had used tobacco residue [11]; eggshells wastes applied by [12]; [13] combined fly ash and bottom ash etc..
Mohanta et.al. has made alumina porous ceramics having a thermal conductivity of 1.2W/m/k and 66% porosity, with sawdust used as the pore-forming agent [37].
Nianhua Chen et. al., [41] has studied the foaming mechanism of foam glass made from graphite and waste bottles by studying the thermal properties, including the maximum foaming conditions.

Castejon et al. [6] developed an automated supervised neural network (NN) diagnosis system of rolling element bearings to classify its condition based on a vibration signal at early stage.
Ugechi et al. [7] developed a diagnosis and prognosis model using artificial neural network (ANN) for vibration parameters classification.
Hajar et al. [9] successfully applied a feed-forward NN to classify a vibration signal of a combined bearing and gear faults simultaneously.
Also, Jena et al. [11] applied the same principle to measure a defect width of a radial ball bearing inner race using acoustic and vibration signal burst duration extracted features.

Sas et al [26] reviewed most of the previous studies that focused on welding parameters for different polymeric materials and are then analyzed.
The bobbin tool model used in the previous study by Bouha et al [51] for welding polyethylene was a very ordinary design.
The study of Bouchouicha et al [57] indicated an empirical association between hardness and tensile strength of the material.

San Keskin et al. [11] have previously produced bacteria-encapsulated cyclodextrin (CD) nanofibers by electrospinning using water as a solvent.
In the study by Škrlec et al. [21], the researchers encapsulated probiotic bacteria in PEO nanofiber and found that the thickening at certain places in the nanofiber was encapsulated probiotic.
Wei et al [22] reported that the probiotic Lactobacillus plantarum were encapsulated with polyvinyl alcohol (PVA) and polyvinyl alcohol/silk fibroin (PVA/SF) nanofibers resulted in a significant thickening of the fibers due to the presence of bacterial cells.
