This paper uses a method for shape reconstruction of a 2-D homogeneous object with arbitrary geometry and known electrical properties. In this method, the object is illuminated by a Gaussian pulse, modulated with sinusoidal carrier plane wave and the time domains’ footprint signal due to object presence is used for the shape reconstruction. A nonlinear feedback loop is used to minimize the diff...

Although object oriented database systems o er more powerful modeling capability than relational database systems their performance su ers from the increased complexity in the data model Thus e cient index mech anisms must be used to improve the performance In this paper two new signature methods for indexing object oriented databases and the associated operations are de scribed The cost models...

Persistent programming systems are generally recognised as the appropriate technology for the construction and maintenance of large, long-lived object based application systems such as software environments. Here some of the advantages of providing all the support required for the software process within a persistent object store with referential integrity are examined. It is shown that powerfu...

Although object-oriented database systems ooer more powerful modeling capability than relational database systems, their performance suuers from the increased complexity in the data model. Thus, eecient index mechanisms must be used to improve the performance. In this paper, two new signature methods for indexing object-oriented databases and the associated operations are described. The cost mo...

Object-oriented conceptual models strive to capture more semantics in order to better represent requirements of real-world applications. Aggregation is a powerful construct for semantic modeling. Intuitively, it relates a composite object to its component objects. This paper presents a new version of aggregation, with a generalized version of cardinality constraints and a new subcategorization ...

A SOLID object introduced into the intestine induces powerful contractions of the circular muscles which transport the object in an aboral direction. This response has been known for a long time (I-S). In the present paper it will be described in greater detail on the basis of visual observations and records of action potentials. In a subsequent paper the underlying neuromuscular mechanism will...

Object recognition is an important task in image processing and computer vision. This paper presents a perfect method for object recognition with full boundary detection by combining affine scale invariant feature transform (ASIFT) and a region merging algorithm. ASIFT is a fully affine invariant algorithm that means features are invariant to six affine parameters namely translation (2 paramete...

This paper motivates and presents the specification and the implementation of an exception handling system for an dynamically typed object-oriented language. A full object-oriented representation of exceptions and handlers, a meta-object protocol to handle using either termination or resumption makes the system powerful as well as extendible and solves various exception handling issues. Three k...
