Solid Freeform Fabrication and Shape Deposition are rapid manufacturing processes which build parts by incremental material deposition and fusion of cross-sectional layers. In this paper, several thermal deposition processes are described for directly fabricating prototype metal shapes using robotically manipulated material deposition systems. A robotic palletizing/part transfer system is also ...

We follow signature-based approach to object-oriented query handling in this paper. The use of signature files as an index for full text search has been widely known and used. Signature file based access methods initially applied on text have now been used to handle set-oriented queries in ObjectOriented Data Bases (OODB). All the proposed methods use either efficient search method or tree base...

AIMS To report abnormal fundus hyperautofluorescence (hyper-AF) and loss of outer retinal layers by spectral domain optical coherence tomography in patients with autoimmune retinopathy (AIR). METHODS Retrospective, observational case series of 14 eyes of 7 patients diagnosed with an AIR for whom colour fundus photographs, fundus AF images and spectral domain optical coherence tomograms (SD-OC...

BACKGROUND AND OBJECTIVE To measure macular choroidal thickness (CT) using spectral-domain optical coherence tomography (OCT) and to investigate the correlation between CT and age, degree of myopia, and history of macular choroidal neovascularization (CNV). PATIENTS AND METHODS A cross-sectional study included 187 highly myopic eyes of 187 patients examined between January and December 2010. ...

BACKGROUND AND OBJECTIVE To determine whether the volumes of macular layers before and after epiretinal membrane (ERM) peeling as measured by spectral-domain optical coherence tomography (SD-OCT) correlated with best-corrected visual acuity (BCVA) or ERM location. PATIENTS AND METHODS Thirty-six eyes with idiopathic ERM and 12 control eyes were imaged preoperatively and postoperatively using ...

The connectionist triangle model of reading aloud proposes that semantic activation of phonology is particularly important for correct pronunciation of low-frequency exception words. Our consideration of this issue (Woollams, Lambon Ralph, Plaut, & Patterson, 2007) reported computational simulations demonstrating that reduction and disruption of this semantic activation resulted in the marked d...

Rule learning is typically used in solving classification and prediction tasks. However, learning of classification rules can be adapted also to subgroup discovery. This paper shows how this can be achieved by modifying the CN2 rule learning algorithm. Modifications include a new covering algorithm (weighted covering algorithm), a new search heuristic (weighted relative accuracy), probabilistic...

In RSA Cryptograms, many modulo calculations are used, but modulo calculation is based on many subtractions and it takes long time to calculate. In this article, we explain about a new modulo calculation algorithm using table. And we proof that upper 3 digits of Radix-2k SD numbers is enough to specify the answer. In the first section, we prepared some useful theorems for operations of Radix-2k...

This paper distils the experience from seven years of knowledge management at sd&m, a German software company with more than 900 employees. For sd&m, knowledge management is a strategic investment with the goal to acquire the right knowledge, to make it accessible to all employees, and to increase their proficiency. Effective knowledge management depends on the right combination of the key elem...

A simple architecture for subsampling LC-based continuous-time SD modulators is introduced. The concept of utilising loop delay to simplify the modulator architecture is generalised to subsampling modulators. Moreover, it is shown that is possible to remove the delay-compensation branch usually used in traditional designs. Removing the delay-compensation branch results in significant simplifica...
