Stereomatching of oblique and transparent surfaces is described using a model of cortical binocular ‘tuned’ neurons selective for disparities of individual visual features and neurons selective for the position, depth and 3D orientation of local surface patches. The model is based on a simple set of learning rules. In the model, monocular neurons project excitatory connection pathways to binocu...

Purpose: A three-dimensional (3D) finite element analysis (FEA) was performed to evaluate the influence of bone quality, on the stress/strain in bone surrounding the implant. Materials and methods: Three-dimensional finite element models created to replicate completely osseointegrated endosseous titanium implants, were used for the purpose of stress analysis. Two study groups consisting of a re...

Automatic building detection plays an important role in many applications. Traditionally, buildings were detected from monocular or multi-view images, DEM or DSM, and laser scanner data. Oblique imagery is a relatively new data source with distinct advantages: it provides detailed information on facades and multiple views from various perspectives. In this paper we present exploration tests usi...

PURPOSE This in-vitro study aimed to evaluate the fracture resistances and failure modes of endodontically treated mandibular premolars restored with endocrowns and conventional post-core retained crowns. MATERIALS AND METHODS Thirty mandibular premolars were assigned into three groups (n=10): GI, intact teeth; GE, teeth with endocrowns; GC, teeth with conventional post-core supported crowns....

purpose: to evaluate the effect of botulinum toxin-a (bta) injection into the inferior oblique (io) muscle in releaving the symptoms of superior oblique (so) palsy. methods: the study was conducted on patients who were referred for acquired so palsy with less than 2 years of duration. about 10-20 unit of bta was injected into the belly of the inferior oblique muscle through the inferotemporal q...

The Gulf of Aden displays an ideal setting to study oblique rift processes since numerous structural data are available onshore and offshore, down to the ocean-continent transition (OCT). We investigate key observations by means of 3D numerical thermo-mechanical experiments on lithospheric scale. The Gulf formed with a rift-normal of -15° azimuth and under the influence of a supposedly 25° tren...

Virtual 3D city models provide powerful user interfaces for communication of 2D and 3D geoinformation. Providing high quality visualization of massive 3D geoinformation in a scalable, fast, and cost efficient manner is still a challenging task. Especially for mobile and web-based system environments, software and hardware configurations of target systems differ significantly. This makes it hard...

this paper proposes a simple but efficient technique to control 3d overhead crane. load musttrack a desired path and not sway more than a reasonable range.the proposed method uses pidcontrol for trolley to track the desired path and fuzzy control compensation to eliminate the loadswing. only the projection of swing angle is applied to design the fuzzy controller. no plantinformation of crane is...

Occurrence of top down and bottom up fatigue cracking in asphaltic pavements is common. Conventional pavement analysis methods ignore the existence of cracks in asphaltic layers. However, it seems that the responses of cracked pavement would not be the same as a pavement without crack. This paper describes effects of crack type, position and length, and vehicles tire inflation pressure and axle...
