The intelligence of a mobile robot is highly dependent on its vision. The main objective of an intelligent mobile robot is in its ability to the online image processing, object detection, and especially visual tracking which is a complex task in stochastic environments. Tracking algorithms suffer from sequence challenges such as illumination variation, occlusion, and background clutter, so an a...

Differential global surface impedance (DGSI) model, a rigorous approach, has been applied to the analysis of three dimensional plasmonic circuits. This model gives a global relation between the tangential electric field and the equivalent surface electric current on the boundary of an object. This approach helps one bring the unknowns to the boundary surface of an object and so avoid volumetric...

one of the modern paradigms to develop an application is object oriented analysis and design. in this paradigm, there are several objects and each object plays some specific roles in applications. in an application, we must distinguish between procedural semantics and declarative semantics for their implementation in a specific programming language. for the procedural semantics, we can write a ...

in this paper the problem of 3d scene and object classification from depth data is addressed. in contrast to high-dimensional feature-based representation, the depth data is described in a low dimensional space. in order to remedy the curse of dimensionality problem, the depth data is described by a sparse model over a learned dictionary. exploiting the algorithmic information theory, a new def...

in an international connection which different factors of legal relation were spread in different countries, bringing of several actions with the same object in different countries court was completely probable. each party with various reasons seeks litigation in a court which provides their interest in better way. however parallel litigation in it he same object impose burdensome charges on li...

This paper analysis approaches and possibilities of executive model aimed to MDA approach. The second part of the article proposes guideline to create executive model, describes basic interactions to object oriented approach and shows possibilities of creating a core of executable model in Java programming language. Annotations are used for executive model object extension. Reflection concept i...

The aim of the COCOON project is to investi gate the design of an object oriented data model with main emphasis on e cient implementation of queries and updates While the nested rela tional kernel of DASDBS is the target physical storage system for COCOON the model is also implemented on top of commercial database sys tems as rst prototypes and to analyze feasibility and compare performance Thi...

Refactorings are usually proposed in an ad hoc way because it is hard to guarantee their soundness with respect to a formal semantics. Usually, even using refactoring tools, developers have to rely on compilation and tests in order to improve their confidence that semantics is preserved, which may not be satisfactory to critical software development. We propose a set of semantics-preserving tra...

The relational model and its extensions are often considered incompatible with object-orientation. However, on the one hand nested relations provide the complex object features demanded by object models. Particularly, powerful query languages exploit the complex data structure while keeping the advantages of the declarative, set-oriented paradigm. On the other hand, object models provide semant...
