A continuity property for local price adjustment mechanisms
Journal of Mathematical Economics, 1999The local continuity property of local price adjustment mechanisms is discussed. Under some conditions to preferences it is shown that the tatonnement process satisfies the continuity property on a subset of the space of all economies. The characterization of these economies for which the tatonnement process is locally stable is given.

Mechanical properties of locally oxidized graphene electrodes
Archive of Applied Mechanics, 2014Graphene has many outstanding mechanical, electronic and optical properties, which makes it an ideal material for future transparent-flexible electronic devices. In such applications, graphene is exposed to atmospheric conditions and must withstand high mechanical stresses without forming cracks or discontinuities, so that the electrical current can ...

Local Mechanical Properties of Various Bone Cements
Key Engineering Materials, 2013Various bone cements with different compositions were prepared in several model configurations which differed in volume (i.e. setting temperature profile) and mode of mixing (manual and vacuum bowl). Local mechanical properties (nanohardness, elasticity modulus) of all experimental states were measured by nanoindentation technique and compared. Role of

Local Mechanical Properties of Abdominal Aortic Aneurysms
ASME 2008 Summer Bioengineering Conference, Parts A and B, 2008Rupture risk of abdominal aortic aneurysms (AAA) based on wall stress analysis may be superior to the currently used diameter-based rupture risk prediction [4; 5; 6; 7]. In patient specific computational models for wall stress analysis, the geometry of the aneurysm is obtained from CT or MR images.

Robotic palpation and mechanical property characterization for abnormal tissue localization
Medical & Biological Engineering & Computing, 2012Palpation is an intuitive examination procedure in which the kinesthetic and tactile sensations of the physician are used. Although it has been widely used to detect and localize diseased tissues in many clinical fields, the procedure is subjective and dependent on the experience of the individual physician.

A new selection mechanism based on hypervolume and its locality property
2013 IEEE Congress on Evolutionary Computation, 2013In this paper, we propose a new selection mechanism based on the hypervolume indicator and on its “locality property”, which is incorporated into the SMSEMOA, giving rise to the so-called improved SMS-EMOA (iSMS-EMOA). Our proposed selection mechanism is validated using standard test functions taken from the specialized literature, having three to six ...

Assessment of Local Heterogeneity in Mechanical Properties of Nanostructured Hydrogel Networks
ACS Nano, 2017Our current understanding of the mechanical properties of nanostructured biomaterials is rather limited to invasive/destructive and low-throughput techniques such as atomic force microscopy, optical tweezers, and shear rheology. In this report, we demonstrate the capabilities of recently developed dual Brillouin/Raman spectroscopy to interrogate the ...

Nanohardness measurements for studying local mechanical properties of metals
Applied Physics A: Materials Science & Processing, 1998Studying local mechanical properties of metallic alloys and composites and their defect structures such as grain boundaries, cracks, and dislocations allows a better understanding and design of these structural materials. With a nanoindenting atomic force microscope (NI-AFM), which uses diamond tips, such measurements are possible on a nanometer scale.
