Anisotropic diiusion has been extensively used as an eecient nonlinear ltering technique for simultaneously performing contrast enhancement and noise reduction, and for deriving consistent scale-space image descriptions. In this paper, we present a general study of anisotropic diiusion schemes based on diierential group-invariant representations of local image structure. We show that the local ...

  Objective(s): Chalcones and their rigid analogues represent an important class of small molecules having anticancer activities. Therefore, in this study the synthesis and cytotoxic activity of new 3-benzylidenchroman-4-ones were described as rigid chalcone analogues.   Materials and Methods: The reaction of resorcinol with 3-chloropropionic acid in the presence of CF3SO3H was a...

Motion of uid elements can be described by the Navier-Stokes equations. They arise from use Law motion to a uid. In this investigation, two dimensional have been engaged. Then they are applied an incompressible viscous movement down inclined plane with net ow. These leads examining effects velocity at various angles inclination and finding boundary layer thickness. Viscous laminar fluid ow also...

Pledgeable assets support more borrowing, which allows for further investment in pledgeable assets. We use this credit multiplier to identify the impact of …nancing frictions on corporate investment. The multiplier suggests that investment–cash ‡ow sensitivities should be increasing in the tangibility of …rms’assets (a proxy for pledgeability), but only if …rms are …nancially constrained. Our e...

Abstract Ongoing global changes are expected to affect the worldwide production of many fisheries and aquaculture systems. Because invertebrates represent a relevant industry, it is crucial anticipate challenges that resulting from current environmental alterations. In this review, we rely on estimated physiological limits six commercialised species sea urchins ( Loxechinus albus , Mesocentrotu...

Assembly operations that involve exible parts differ greatly from rigid-part assembly due to the capacity of the parts to comply with motions of the manipu-lators by yielding to the contact forces. This natural compliance can be exploited in the design of tasks involving the manipulation of exible loads. Namely, using knowledge about the force vector eld generated by conservative restoring forc...

The concept of limited #exibility, originally applied to production planning, has shown that many bene"ts of totally #exible systems can be obtained by less #exible systems. This concept is here applied to shop #oor control. Limited #exibility is considered as a particular routing #exibility that allows system resources to process some products according to a logic chain, as an intermediate con...

Future database software (i.e., applications, systems) can no longer be monolithic. Database technology is evolving towards cooperation and integration. Having components which inter-operate, being self-tuned, scalable and available are new challenges. Event infrastructures are well adapted to support software components integration. Therefore, we propose a exible event service which can be use...

Concerns about drinking water contamination through lead service lines, which connect street mains to homes in many cities the United States, might hinder resource-constrained municipalities from performing important infrastructure upgrades. Construction on disturb lines and increase levels water. We estimate effects of main maintenance children's blood by exploiting unique geocoded data over 2...
