A new approach is introduced to 3-D parameterized object estimation and recognition. Though the theory is applicable for any parameterization, we use a model for which objects are approximated by patches of spheres, cylinders, and planes---primitive objects. These primitive surfaces are special cases of 3-D quadric surfaces. Primitive surface estimation is treated as parameter estimation using ...

In this paper we find sufficient conditions on primitive inverse topological semigroup S under which: the inversion inv : (H(S)) (H(S)) is continuous; we show that every topologically periodic countable compact primitive inverse topological semigroups with closed H-classes is topologically isomorphic to an orthogonal sum P i2= Bi (Gi) of topological Brandt extensions Bi (Gi) of countably compac...

The paper presents research results related to an ongoing European IST project called MECASP (Maintenance and improvement of componentbased applications diffused in ASP mode), aiming at developing a set of tools for tracking the evolution of heterogeneous software (built using heterogeneous development tools, such as Java IDEs, relational DBMSs, CASE tools, document editors etc). MECASP cannot ...

Digital imaging is becoming a major information resource within the Internet. Although image access tools are primitive today, they are evolving rapidly. In this paper we look at content descriptor-based and pixel-based image queries for accessing large image libraries. The access methods will be combined and enhanced in future retrieval systems.

In this paper we present an algorithm for computing all algebraic intermediate subfields in a separably generated unirational field extension (which in particular includes the zero characteristic case). One of the main tools is Gröbner bases theory, see [BW93]. Our algorithm also requires computing computing primitive elements and factoring over algebraic extensions. Moreover, the method can be...

STROBE is a system that provides object-oriented programming support tools for INTERLISP. It offers a primitive foundation with which more complex structured object representation schemes can be constructed. STROBE implements multiple resident knowledge bases, tangled generalization hierarchies, flexible inheritance of properties, procedural attachment, and event-sensitive procedure invocation.

In this paper, we provide an overview of Logistical Runtime System (LoRS). LoRS is an integrated ensemble of tools and services that aggregate primitive (best effort, faulty) storage allocations to obtain strong properties such as capacity, performance, reliability, that Grid applications desire. The paper focuses on the design and implementation of LoRS, as well as the storage scheduling decis...

this is the report of a mandibular neuroectodermal/ewing sarcoma in an 8-year-old male cross breed dogthat is unique because of tumor origin location. pedunculated, ulcerative, firm 6.0 × 4.0 × 5.5 cm tumor masseffaced the bone at the rostral part of the mandible and had a white-sanguineous color at cross sectionappearance. histopathologically, small round blue cell tumor was diagnosed. immunoh...
