Towards Knowledge Morphing: A Triangulation Approach To Link Tacit And Explicit Knowledge, Fehmida Hussain, Syed Sibte Raza Abidi, Syed Ali Raza Aug 2005

Towards Knowledge Morphing: A Triangulation Approach To Link Tacit And Explicit Knowledge, Fehmida Hussain, Syed Sibte Raza Abidi, Syed Ali Raza

International Conference on Information and Communication Technologies

Current knowledge management systems are largely designed to deal with a single knowledge modality. Given the diversity of knowledge modalities that encompass any given topic/problem it is reasonable to demand access and use of all available knowledge, irrespective of their representation modality, to derive a knowledge-mediated solution. This calls for selecting all knowledge elements (represented in different modalities) that are relevant to the solution of the problem at hand. Thus here we pursue the specification and implementation of such a knowledge-mediated solution using a triangulation approach leading to Knowledge Morphing. In this paper we present a tacit-explicit knowledge morphing (TEKM) …

Using Software Engineering Principles To Develop Reusable Business Rules, Saqib Ali, Ben Soh, Torab Torabi

International Conference on Information and Communication Technologies

Nowadays, businesses need a system that can provide flexibility, reusability and simplicity for their business solutions. However, if business logics or rules are implemented using procedural paradigms, then the business systems will become more complex. In this paper we treat business logics separate from system logics, whereby we analyse a business by describing its rules and developing a set of rule statements. These business rules will be treated as a separate component in the design and implementation of the system. We have found that our proposed method leads to a system, which is more customisable, flexible, efficient, and reusable, in …

A New Approach For Anti-Aliasing Raster Data In Air Borne Imagery, Fahim Arif, Muhammad Akbar

International Conference on Information and Communication Technologies

Air borne sensed data is in the form of raster data. Aliasing is always present in a sampled image causing artifact error. To reduce possible aliasing effects, it is a good idea to blur an image slightly before applying a resampling method on it. This paper presents a technique for anti-aliasing remotely sensed images. The technique uses Gaussian low pass filter (GLPF) for generation of slight blur. Then resampling of raster data is performed with the help of bilinear interpolation. Algorithm is developed in MATLAB using some inbuilt functions.

A Performance Comparison Of Data Encryption Algorithms, Aamer Nadeem, Dr. M. Younus Javed Aug 2005

A Performance Comparison Of Data Encryption Algorithms, Aamer Nadeem, Dr. M. Younus Javed

International Conference on Information and Communication Technologies

The principal goal guiding the design of any encryption algorithm must be security against unauthorized attacks. However, for all practical applications, performance and the cost of implementation are also important concerns. A data encryption algorithm would not be of much use if it is secure enough but slow in performance because it is a common practice to embed encryption algorithms in other applications such as e-commerce, banking, and online transaction processing applications. Embedding of encryption algorithms in other applications also precludes a hardware implementation, and is thus a major cause of degraded overall performance of the system. In this paper, …

Real Time Object Tracking Using Bma, Zeeshan Hameed Khan, Muhammad Aurangzeb Aug 2005

Real Time Object Tracking Using Bma, Zeeshan Hameed Khan, Muhammad Aurangzeb

International Conference on Information and Communication Technologies

This paper describes real time object tracking using block matching algorithm (BMA). Emphasis is made on the development of techniques for tracking a user-selected object through digital image sequences in multimedia systems. The ability to track objects in sequences is useful in situations where the motion of objects is important. It is also useful when a moving object is difficult to see and needs to be highlighted. A tracking tool is also of benefit to the developers of a multimedia system to automatically 'mark up' a moving object so a user of the system can select it and manipulate it.
