چکیده

where Mkk represents the trace components of the moment tensor,  and  are Lame constants. These results imply that the damage evolution and the accumulation of relative crack volume are also estimated from the moment tensor analysis. From moment tensors determined in bending tests of concrete specimens with a notch [Ohtsu & Ohtsuka 1998], the damage and the accumulation of crack volume were estimated. In the case of the center-notched specimen (type CC), the damage suddenly increased, while the damage evolution was gradual in the off-center notched specimen (type OC).

. ge n - ph ] 1 3 M ar 2 00 7 1 The Intrinsic Electric Dipole Moment and the “ Time - Space ” Intrinsic Angular Momentum

In a geometric approach to special relativity it is found that the spin four-tensor S can be decomposed into two 4-vectors, the usual “space-space” intrinsic angular momentum S and a new one, the “time-space” intrinsic angular momentum Z, which are both equally well physical quantities. It is also shown that an electric dipole moment (EDM) of a fundamental particle, as a four-dimensional geomet...

Molecular Ordering of 4-Acetyl-2′-Nitrobiphenyl – A Computational Analysis

The molecular ordering of some biphenyl derivatives like 4-acetyl-2′-nitrobiphenyl (ANBP), 4-nitro2-biphenylamine (NBPA) and 4-acetyl-3′-chlorobiphenyl (ACBP) has been examined using basic concepts of quantum mechanics and intermolecular forces. The CNDO/2 method has been employed to compute the net atomic charge and atomic dipole components at each atomic centre. The modified Rayleigh-Schrödin...

Determination of metrics by boundary energy

This paper reformulates a problem of Sharafutdinov [4] and extend the new variant from the single-time context to the multi-time context. Section 1 is dedicated to the single-time case. It starts with well-known facts of describing geodesics as extremals. Then it is formulated and studied the problem of determination of a metric by the boundary energy. The linearization of this problem leads to...

Spectral Decomposition of a 4-rank Tensor and Applications to Generalised Diffusion Tensor Imaging

Introduction: In 2003 Ozarslan et al introduced Generalised DTI, and showed how the data from a diffusion MRI experiment can be described by a higher rank tensor [1]. In 2005 the same authors proposed two generalised anisotropy metrics that can be calculated from any n-rank tensor [2]. The normalisation of these metrics is achieved by using a scaling function, with parameters that can be change...
