SFF processes have demonstrated the ability to produce parts with locally controlled composition. In the limit, processes such as 3D Printing can create parts with composition control on the length scale of 100 microns. To exploit this potential, new methods to model, exchange, and process parts with local composition need to be developed. An approach to modeling a part’s geometry, topology, an...

Mahmood) Shape from focus (SFF) is one of the optical passive methods for three dimensional (3D) shape recovery of an object from its two dimensional (2D) images. The focus measure plays important role in SFF algorithms. Mo...

PURPOSE Nursing facilities that are determined to have a greater number of quality problems, more serious problems than average, and a demonstrated pattern of quality problems are included in the Special Focus Facility (SFF) initiative. The purpose of this research was to provide descriptive information on these SFFs and to examine the quality characteristics of these facilities. DESIGN AND M...

Male to female gender identity disorder (MTF/GID) is a rare condition. Such patients tend complain that their speaking fundamental frequency (SFF) does not fit because it too low. Type 4 thyroplasty (TP4) conversely increases the pitch of SFF as tension vocal fold tightened causing become high-pitched. While life-threatening for with MTF/GID, can cause substantial worry and stress. TP4 therefor...

OBJECTIVE We evaluated the effects of tooth displacement on frictional force when conventional ligating lingual brackets (CL-LBs), CL-LBs with a narrow bracket width, and self-ligating lingual brackets (SL-LBs) were used with initial leveling and alignment wires. METHODS CL-LBs (7th Generation), CL-LBs with a narrow bracket width (STb), and SL-LBs (In-Ovation L) were tested under three tooth ...

A research program has been initiated to develop a Solid Freeform Fabrication (SFF) technology for combining nanosized particulate or fiber reinforcements with a photocurable thermoset matrix resin in order to produce functional graded composites. The composites that are being studied initially are optical components filled with nano-phase ceramic particles that form gradient refractive index l...

Shape-from-focus (SFF) uses a sequence of space-variantly defocused observations captured with relative motion between camera and scene. It assumes that there is no motion parallax in the frames. This is a restriction and constrains the working environment. Moreover, SFF cannot recover the structure information when there are missing data in the frames due to CCD sensor damage or unavoidable oc...

Historically, the field of image processing grew from electrical engineering as an extension of the signal processing branch, whereas the discipline of computer science was largely responsible for developments in computer vision. An image processing operation typically define a new image in terms of existing image. On the other hand, computer vision deals with meaningful representation of an en...

The potential of a Super Flavor Factory (SFF) for searches of New Physics is reviewed. While very high luminosity B physics is assumed to be at the core of the program, its scope for extensive charm and τ studies are also emphasized. The possibility to run at the Υ(5S) as well as at the Υ(4S) is also very briefly discussed; in principle, this could provide very clean measurements of Bs decays. ...

OBJECTIVE To evaluate the effects of tooth displacement and vibration on frictional force and stick-slip phenomenon (SSP) when conventional brackets were used with a levelling/alignment wire. MATERIALS AND METHODS The samples consisted of six groups (n = 10 per group) with combinations of tooth displacement (2mm lingual displacement [LD], 2mm gingival displacement [GD], and no displacement [c...
