Gooya et al. [5][6] proposed an energy edge detector for vessel segmentation using the structural tensor.
Descoteaux et al. [8] proposed a boundary vessel segmentation by convolving an image with Gaussian filters at multiple scales to drives the shape evolution.
Also, other interesting methods have been presented in Manniesing et al.[10], Nemitz et al. [11], Hernández Hoyos et al. [12], Orkisz et al. [13].
Description of the proposed molde The model proposed by Li et al.[24] is based on Mumford-Shan model, so it is still a piecewise constant.

Initial and boundary conditions after the laser pulse The initial conditions for the titanium plasma are: XTi =1, Ti,Ti=2.8104 (K) and the initial speed given by Chen et al [4]is: The specific heats ratio for monatomic gases is γ=5/3, kB the Boltzmann constant, and mat the mass of a titanium atom.
This result is confirmed by a study developed by Sentis et al [5].
The results show that the average plasma temperature increases with the pressure of ambient gas in agreement with Gomes et al [6].

Introduction
Nowadays materials are tailor made for particular applications inorder to meet specific design criteria (El Baradie (1)).
In the field of automobile, MMCs are used for piston, piston rings, connecting rods, brake drum and cylinder head due to its better corrosion resistance and wear resistance (Natarajan et al (3), Prasad et al (4)).
The increase in normal load and sliding velocity increases the magnitude of wear (Ramachandra et al (10)).
The wear rate of Al/flyash composite is reduced by increasing flyash content in AMCs.

EL and ER are elasticity modulus of orthotropic principal axis.
(1) By keeping EL=16.27GPa, ER=11.03GPa, GLR=1.17GPa, VLR=0.49 and α2=S/Y=9.25/45 fixed, we select strength ratio α1 at 2.0, 2.5, 3.0, 3.5 and 4.0, respectively.
(2) By keeping EL=16.27GPa, ER=11.03GPa, GLR=1.17GPa, VLR=0.49 and α1=X/Y=100/45 fixed, we select strength ratio α2 at 0.1, 0.15, 0.2, 0.25 and 0.3, respectively.
(3) Now we investigate the effect of different toughness ratio r1=EL/ER, r2=ER/GLR on plastic zone.

Intermediate Phase Growth of Mg-Al Diffusion Couple Under a Strong
Static Magnetic Field
Dong Jie1,a, Z.
The effects of magnetic field on atom diffusion in alloy was previously studied by Youdelis [5,6] and nakajima [7] many years ago using static magnetic field, and recently by Liu et el
Usually, two intermediate phases will form in Al-Mg diffusion couple after annealing.
Two intermediate phases, i.e. β and γ, in Mg-Al couple formed after annealing under different intensity of a strong static magnetic field.
The parabolic rate law is obeyed in the growth of the intermediate phases in Mg-Al couples under the static magnetic field. 2.

A composite containing A356 Al alloy as matrix and ZrB2 particles was made in an induction furnace by mixing Al-15Zr and Al-8B master alloys with Zr:B weight ratio of 9:2.
Al-15% Zr and Al-8% B master alloys were first heated up to 1000°C in a graphite crucible by using a medium frequency induction furnace.
