Image-based effector servoing is a process of perception-action cycles for handling a robot effector under continual visual feedback. Apart from the primary goal of manipulating objects we apply servoing mechanisms also for determining camera features, e.g. the optical axes of cameras, and for actively changing the view, e.g. for inspecting the object shape. A peg-in-hole application is treated...

In this paper we consider the problem of processing scanned datasets of man-made scenes such as building interiors and office environments. Such datasets are produced in huge quantity and often share a simple structure with sharp crease lines. However, their usual acquisition with mobile devices often leads to poor data quality and established reconstruction methods fail – at least at reconstru...

Because of the complexity of the architecture of the foot radiographic diagnosis is often difficult and injury sometimes unrecognised. Dislocations may be missed on plain radiography because in two dimensions it is difficult to appreciate displacement ofa single bone or disruption of its articulation. Moreover, isolated tarsal dislocations are uncommon and unfamiliarity alone may contribute to ...

ÐWith a huge amount of data stored in spatial databases and the introduction of spatial components to many relational or object-relational databases, it is important to study the methods for spatial data warehousing and OLAP of spatial data. In this paper, we study methods for spatial OLAP, by integration of nonspatial OLAP methods with spatial database implementation techniques. A spatial data...

Forefoot adduction is a common condition between metatarsus adductus, Z-shaped foot and residual clubfoot. This deformity is located in a pure transverse plane at Lisfranc’s joint. Isolated metatarsus adductus is corrected spontaneously for the majority of newborns. In rare uncorrected cases, it could result in Z-shaped foot with a functional hindfoot valgus to equilibrate the resistant metatar...

OBJECTIVES This study aims to investigate the relationship between clinical and US findings together with the prevalence and distribution of US findings indicative of monosodium urate (MSU) crystal deposition within the foot in patients with gout. METHODS A total of 50 patients with gout attending the in-patient and the out-patient clinics of the Rheumatology Departments were prospectively en...

This paper formally proposes a problem about the efficient utilization of the four dimensional space-time. Given a cuboid container, a finite number of rigid cuboid items, and the time length that each item should be continuous baked in the container, the problem asks to arrange the starting time for each item being placed into the container and to arrange the position and orientation for each ...

A Chinese boy, aged six ‘ears, was seen at the Chung Shan Memorial Hospital, Shanghai, on August 12, i947, for discharging sinuses over the left neck, left elbow and dorsum of the left foot. ille sinuses, which had been present for more than a year, began as multiple nodules in the neck, and ruptured. The clinical diagnosis was tuberculosis of the cervical glands, left elbow alld left foot. Rad...

Cells can secrete biotherapeutic molecules that can replace or restore host function. The transplantation of such cells is a promising therapeutic modality for the treatment of several diseases including type 1 diabetes mellitus. These cellular grafts are encapsulated in semipermeable and immunoisolative membranes to protect them from the host immune system, while allowing the transport of nutr...
