Live migration of virtual machine (VM) is one of the most important virtualization technologies to facilitate the management and improve the performance of data centers. In this paper, we propose a fast convergent live migration approach called FMC. It is a self-adaptive method which synchronizes the state of the VM migrated between the source and target host by log tracing and replaying instea...

The UCVM (figure 1A) has no mean velocity component (μ(t) = 0) and a real, non-negative relaxation parameter α. Defined as α = 1 τ , τ represents a characteristic time scale of auto-correlation [1, 2]. The parameter β has units of velocity × time−1/2 which makes it difficult to interpret biologically. However, the mean squared speed of the UCVM is given by η2 ≡ lim t→∞ 〈 |v(t)|2 〉 = β2τ , such ...

On extrinsic geometry of unit normal vector fields of Riemannian hyperfoliations. Abstract We consider a unit normal vector field of (local) hyperfoliation on a given Riemannian manifold as a submanifold in the unit tangent bundle with Sasaki metric. We give an explicit expression of the second fundamental form for this submanifold and a rather simple condition its totally geodesic property in ...

A method of detecting moving objects from an image sequence acquired by a single moving camera is presented. No assumptions about the movement of the camera platform is made. Motion detection from a moving platform is a non-trivial problem as the moving camera induces apparent motion in the entire image. The epipolar geometric constraint is used between matched points in consecutive image frame...

the neighborhood has had a long history in iranian urbanization. since urban plans wereintroduced by the authorities to shape urban development in iran half a century ago, the concept of iranian traditional neighborhood has been neglected gradually. the concept of neighborhood has not found the appropriate status in urban design and planning yet. one of the main reasons is that academics, profe...

We analyze a continuous and discrete symmetries of the maximum lifetime problem in two dimensional sensor networks. We show, how a symmetry of the network and invariance of the problem under a given transformation group G can be utilized to simplify its solution. We prove, that for a G-invariant maximum lifetime problem there exists a G-invariant solution. Constrains which follow from the G-inv...

Mechanical neck disorder is a widespread and non-neurological musculoskeletal condition resulting from modern lifestyles. Presently, the fundamental electrophysiological properties of the motor units of the sternocleidomastoid muscles and the characteristics of the short-term synchronization of the motor unit in patients with neck pain are ambiguous. This study therefore aims to clarify the fun...

We construct fundamental domains for arithmetic subgroups of Γ = GL2(Fq [t]). Given ∆ ⊇ Γ(a) we construct a contracted form T of the Bruhat-Tits tree T and a fundamental domain F of ∆ acting on T. We define a lift of F to F ⊂ T called the “bipartite” lift. We show that F is a fundamental domain of ∆ acting on T precisely when F is “∆-compressed.”
