suppose $pi:mathcal{a}rightarrow mathcal{b}$ is a surjective unital $ast$-homomorphism between c*-algebras $mathcal{a}$ and $mathcal{b}$, and $0leq aleq1$ with $ain  mathcal{a}$. we give a sufficient condition that ensures there is a proection $pin mathcal{a}$ such that $pi left( pright) =pi left( aright) $. an easy consequence is a result of [l. g. brown and g. k. pedersen, c*-algebras of real...

This paper presents an approach for text line segmentation which combines connected component based and projection based information to take advantage of aspects of both methods. The proposed system finds baselines of each connected component. Lines are detected by grouping baselines of connected components belonging to each line by projection information. Components are assigned to lines accor...

Many applications in industry require non-contact, fast and accurate measurement of both surface profile and deformation field for manufacturing quality control and structural testing purposes. The fringe projection technique has been widely used due to its high accuracy and spatial resolution in measuring shape and out-of-plane displacement fields, but it cannot identify in-plane displacements...

BACKGROUND The safety and effectiveness of the Natrelle Style 410 highly cohesive silicone gel breast implant (Allergan, Inc., Irvine, Calif.) in full or moderate height and projection have been shown in a 10-year study. Extra-full projection implants may be an appropriate option for some women undergoing breast reconstruction. METHODS A total of 2795 women received at least one Natrelle 410 ...

We investigate the semantic effects of focus in complement clauses of various kinds of complement-taking predicates and argue that the empirically attested readings are predicted by the interplay of two principles: (i) embedded focus locally triggers the presupposition that the existential closure of the background is true, (ii) embedding predicates differ in their presupposition projection pro...

In this study, gene expression profile classification is done via sparse representation in the random feature Space, which is obtained by either random projection or nonlinear random mapping used in Extreme learning machine (ELM). The numerical experiment shows that sparse representation has slightly better performance than ELM.

A non-destructive technique is presented to determine the refractive index profile of holey fiber preforms. The holes are filled with index matching oil and the holey preform deflection data is measured. An improved optical path-length formula and back projection method is used to reconstruct the two-dimensional filled holey fiber preform refractive index distribution.

We have developed an automatic algorithm to detect the skin profiles in the volumetric data acquired by photoacoustic microscopy for subcutaneous vasculature imaging. This algorithm analyzes the relationship between amplitudes of photoacoustic signals generated from the skin surface and underlying blood vessels to achieve a rough estimation of the skin profile. A better approximation of the ski...

different methods arising from scientific investigation for removing noise from chaotic signals have been introduced and one of their best is local projection approach. the local projection approach projects the chaotic data in the neighborhood onto the hyper-plane. selection of neighborhood radius has a direct impact on its performance. a noticeable feature associated with chaotic trajectories...

introduction: monte carlo (mc) is the most common method for simulating virtual spect projections. it is useful for optimizing procedures, evaluating correction algorithms and more recently image reconstruction as a forward projector in iterative algorithms; however, the main drawback of mc is its long run time. we introduced a model based method considering the effect of body attenuation and i...
