Object identity and dynamic recomposition of components

P. Costanza, O. Stiemerling, A.B. Cremers
Proceedings Technology of Object-Oriented Languages and Systems. TOOLS 38  
Dynamic recomposition of components in a program imposes advanced requirements on the expressive power of object-oriented programming languages.  ...  For example, the replacement of a component with another reveals consistency problems stemming from the fact that the concept of object identity tries to fulfil the distinct purposes of reference and comparison  ...  This work is partially located in the TAILOR project at the Institute of Computer Science III of the University of Bonn and has been supported by Deutsche Forschungsgemeinschaft (DFG) under grant CR 65  ...

Perimorph: run-time composition and state management for adaptive systems

E.P. Kasten, P.K. McKinley
2004 24th International Conference on Distributed Computing Systems Workshops, 2004. Proceedings.  
This paper addresses a key issue that arises in run-time recomposition of software: the transfer of nontransient state between old components and their replacements.  ...  The operation of Perimorph is demonstrated through the implementation and testing of a 2D/3D digital elevation mapping application that supports recomposition and handoff among networked devices with varying  ...  However, injection of state is typically back into an identical process or component, DACIA [21] is a system designed to provide modular construction and runtime reconfiguration and recomposition.  ...

Security and Trustworthiness Threats to Composite Services: Taxonomy, Countermeasures, and Research Directions [chapter]

Per Håkon Meland, Muhammad Asim, Dhouha Ayed, Fabiano Dalpiaz, Edith Félix, Paolo Giorgini, Susana Gonzáles, Brett Lempereur, John Ronan
2014 Lecture Notes in Computer Science  
Our main contributions are a taxonomy of threats for composite services in the Future Internet, which organises thirty-two threats within seven categories, and a corresponding taxonomy of thirty-three  ...  These results have been devised from analysing service scenarios and their possible abuse with participants from seventeen organisations from industry and academia.  ...  Such a threat occurs because users are typically unaware of the identity of individual providers, of their geographic distribution, and of the laws that apply in the countries where the service component  ...

Implementation and Comparative Study of Image Fusion Algorithms

Shivsubramani Krishnamoorthy, K P Soman
2010 International Journal of Computer Applications  
The objective of the paper is to assess the wide range of algorithms together, which is not found in the literature.  ...  Image Fusion is a process of combining the relevant information from a set of images, into a single image, wherein the resultant fused image will be more informative and complete than any of the input  ...  The two commonly used order for comparing vector quantities are the component-wise (<) order and strict component-wise order (<<). f(a m )<f(a n ) iff f i (a m )≤ f i (a n ), ∀ and f(a m )≠f(a n ).  ...
