The free edges of layered structures require special attention in design processes. Due to the discontinuous material properties, singular stress concentrations occur where layer interfaces meet edge. These bi-material points have be closely examined as possible starting for delamination In present study, we propose an efficient approximate closed-form method analyze interlaminar shear stresses...

purpose: to evaluate visual outcomes and intraocular pressure (iop) after single-site phacotrabeculectomy with mitomycin c in patients with senile cataract and primary open angle glaucoma (poag), pseudoexfoliative glaucoma (pxg), or chronic angle closure glaucoma (cacg). methods: in this retrospective study, patients older than 50 years who had significant cataracts (bcva £ 20/60) and uncontrol...

Switched reluctance motor (SRM) drive has remarkable characteristics that make it attractive for high-speed applications. As the motor's speed increases the shape of the current waveform changes in such way that limits the production of motoring torque. At high speeds, it is possible for the phase current never reaches the desired value due to the self e.m.f. of the motor, therefore, the torque...

The discrete element method (DEM) has been used as a popular simulation method in order to verify the designs by visualizing how materials flow through complex equipment geometries.  Although DEM simulation is a powerful design tool, finding a DEM model that includes all real material properties is not computationally feasible.  In order to obtain more realistic results, particle energy loss du...

An important issue in image analysis is the detection of features in images. Problems occur, when the images contain noise or are rotated. An example for a rotation invariant feature is the apex angle. However, apex angle detection is only expedient, on a special class of images, therefore in this thesis only images with up to two overlaid intrinsically one dimensional structures are considered...
