The technical and commercial potential of an incremental ring rolling process
Allwood, JM; Kopp, R; Michels, D; Music, O; Oztop, M; Stanistreet, TF; Tekkaya, AE; Tiedemman, I (Elsevier BV, 2005-01-01)
A novel incremental ring rolling process is proposed, in which a narrow mandrel is moved both radially and axially. The process has potential to allow flexible near-net-shape forming of both hot and cold rings, and has bee...
An engineered pancreatic cancer model with intra-tumoral heterogeneity of driver mutations
Moon, Hye-ran; Ozcelikkale, Altug; Yang, Yi; Elzey, Bennett D.; Konieczny, Stephen F.; Han, Bumsoo (Royal Society of Chemistry (RSC), 2020-10-01)
Pancreatic ductal adenocarcinoma (PDAC) is a complex disease with significant intra-tumoral heterogeneity (ITH). Currently, no reliable PDAC tumor model is available that can present ITH profiles in a controlled manner. We...
An ontology-based multi-agent virtual enterprise system (OMAVE): part 2: partner selection
Sadigh, Bahram Lotfi; Nikghadam, Shahrzad; ÖZBAYOĞLU, AHMET MURAT; ÜNVER, HAKKI ÖZGÜR; DOĞDU, ERDOĞAN; KILIÇ, SADIK ENGİN (Informa UK Limited, 2017-01-01)
A virtual enterprise (VE) is a collaboration model between multiple business partners in a value chain. The VE model is particularly feasible and appropriate for small- and medium-sized enterprises (SMEs) and industrial pa...
An ontology-based multi-agent virtual enterprise system (OMAVE): part 1: domain model<bold>l</bold>ing and rule management
Sadigh, Bahram Lotfi; ÜNVER, HAKKI ÖZGÜR; Nikghadam, Shahrzad; DOĞDU, ERDOĞAN; ÖZBAYOĞLU, AHMET MURAT; KILIÇ, SADIK ENGİN (Informa UK Limited, 2017-01-01)
New advancements in computers and information technologies have yielded novel ideas to create more effective virtual collaboration platforms for multiple enterprises. Virtual enterprise (VE) is a collaboration model betwee...
A Multi-Agent System Model for Partner Selection Process in Virtual Enterprise
Virtual Enterprise (VE) is a collaboration model between multiple business partners in a value chain. VE information system deals with highly dynamic information from heterogeneous data sources. In order to manage and stor...
Simulation of a Standard Store Separated from Generic Wing
Sheharyar, M.; Uddin, E.; Ali, Z.; Zaheer, Q.; Mubashar, A. (2018-11-01)
Evaluation of store separation experimentally is expensive; time consuming and dangerous as human risks are involved. This results in development of computational methods to simulate the store separation. Store separation ...
Design and geometrical optimization of the veranda roof pattern with the target of visual comfort in Shareman as one of the Solar Decathlon China 2013 houses
Rezaian, Elnaz; Amini, Kasra; Matoor, Soha; Milani, Sina A.; Fayaz, Rima (2015-06-01)
Veranda as one of the main elements of spatial hierarchy in the traditional Iranian architecture is responsible for providing visual and thermal comfort and energy saving, in the interior and to some extent exterior beside...
A survey of partner selection methodologies for virtual enterprises and development of a goal programming-based approach
Nikghadam, Shahrzad; Sadigh, Bahram Lotfi; ÖZBAYOĞLU, AHMET MURAT; ÜNVER, HAKKI ÖZGÜR; KILIÇ, SADIK ENGİN (2016-07-01)
A virtual enterprise (VE) is a platform that enables dynamic collaboration among manufacturers and service providers with complementary capabilities in order to enhance their market competitiveness. The performance of a VE...
Kara, Dogacan; Donmezer, Nazli; Canan, Talha Furkan; ŞEN, ÖZLEM; ÖZBAY, Ekmel (2016-07-14)
Field plated GaN high electron mobility transistors (HEMTs) are widely preferred amongst other GaN HEMT devices because of their ability to regulate electric field at high power densities. When operated at high power densi...
Numerical investigation on the effect of transversal fluid field deformation on heat transfer in a rod bundle with mixing vanes
Tas-Koehler, Sibel; Lecrivain, Gregory; Krepper, Eckhard; Unger, Sebastian; Hampel, Uwe (Elsevier BV, 2020-05-01)
Spacer grids of fuel rod assemblies are equipped with vanes, which promote flow mixing and turbulence within and across the sub-channels, thereby enhancing the heat transfer. First, a literature study about the various eff...
