Leading Firms As Knowledge Gatekeepers In A Networked Environment, Deogratias Harorimana Mr Nov 2008

Leading Firms As Knowledge Gatekeepers In A Networked Environment, Deogratias Harorimana Mr

Dr Deogratias Harorimana

This chapter introduces the role of the knowledge gatekeeper as a mechanism by which knowledge is created and transferred in a networked environment. Knowledge creation and transfer are essential for building a knowledge based economy. The chapter considers obstacles that inhibit this process and argues that leading firms create a shared socio-cultural context that enables the condivision of tacit meanings and codification of knowledge. Leading firms act as gatekeepers of knowledge through the creation of shared virtual platforms. There will be a leading firm that connects several networks of clients and suppliers may not interact directly with one another, but …


Using Triz For Maximizing Information Presentation In Gui, Umakant Mishra Oct 2008

Using Triz For Maximizing Information Presentation In Gui, Umakant Mishra

Umakant Mishra

The modern software tools provide numerous graphic elements in their GUI, which demand more and more screen space. As the size of a display screen cannot be extended beyond a limit, it is typically seen as a constraint in a graphical user interface.

Looking from a TRIZ perspective, the computer screen should display all the information that the user needs (Ideal Final Result). There are various methods of addressing the problem of screen space, some of which are, ”using icons for windows”, “the desktop metaphor”, “the large virtual workspace metaphor”, “multiple virtual workspaces”, “overlapping windows” and “increasing dimensions” etc.

There …


Using Triz To Improve Navigation In Gui, Umakant Mishra Oct 2008

Using Triz To Improve Navigation In Gui, Umakant Mishra

Umakant Mishra

A typical user interface consists of several buttons, menus, windows, trees and other type of controls. The increased number of GUI elements and complexities of the GUI controls necessitate the user to acquire certain level of skill and efficiency in order to operate the GUI. There are many situations which further make the navigation difficult. Ideally the user should face no difficulties in navigating through the user interface. Any operation in the graphical user interface should require minimum pointer operations from the user (Ideal Final Result). This objective of a graphical user interface has led to several inventions trying to …


Using Triz For Minimizing Cursor Movements In Gui, Umakant Mishra Oct 2008

Using Triz For Minimizing Cursor Movements In Gui, Umakant Mishra

Umakant Mishra

Although a GUI is a revolutionary development over its predecessors, it suffers from a typical shortcoming that it requires a lot of pointer movements. As pointer movement is a slow process it affects the overall performance of a GUI operation. Besides too much pointer movement can frustrate a user. Hence, it is desirable to reduce the pointer movements while performing any action through a typical GUI. Ideally the user need not move the pointer to initiate a GUI based operation. In other words the pointer itself should automatically move onto the desired location on the graphical user interface (Ideal Final …

Inventions On Improving Visibility Of Gui Elements, Umakant Mishra

Umakant Mishra

The evolution of computing technology has witnessed tremendous growth in the processing power of the computer. The memory and storage capabilities are also increasing year after year. In contrast to the above, the display area of a PC monitor remains the same. This inhibits the productivity of a computer, as the user does not just have enough view area to interact with the computer. Ideally the display screen should accommodate all required data, objects and GUI elements for user interaction. If some data or object is hidden behind or remaining beyond the display area, it should automatically come to the …


Inventions On User Friendliness Of A Gui- A Triz Based Analysis, Umakant Mishra Oct 2008

Inventions On User Friendliness Of A Gui- A Triz Based Analysis, Umakant Mishra

Umakant Mishra

Although a GUI is considered to be convenient it still has certain shortcomings like ambiguity of pictorial symbols, difficulty of cursor movements, difficulty of interacting with smaller graphic elements, likeliness of making mistakes by slip of fingers, demand of more screen space, difficulty of searching in nested containers etc. Many users fail to operate a computer satisfactorily because of the special skill or training required to operate it. In order to avoid this problem, it is necessary to design the user interface in such a way that even an untrained user should also be able to operate the computer effectively …


Using Triz To Design Error-Free Gui, Umakant Mishra Oct 2008

Using Triz To Design Error-Free Gui, Umakant Mishra

Umakant Mishra

A graphical user interface has a lot of advantages over its predecessors. Its beauty, simplicity, adaptability, user-friendliness, visual clarity, speed and ease of operation have made it popular and suitable to a broad range of users. But a GUI also has certain limitations. Like any other type of user interface, a GUI can also be operated wrongly which may yield undesirable results. A good GUI should be intelligent to determine user’s intention and disallow him doing wrong operations. A less error-prone GUI is certainly more effective and efficient. Ideally the GUI should prevent users from doing any mistake while operating …


Arranging Display Of Gui Elements- A Triz Based Analysis, Umakant Mishra Oct 2008

Arranging Display Of Gui Elements- A Triz Based Analysis, Umakant Mishra

Umakant Mishra

One of the biggest drawbacks of the graphical user interface is that it consumes the active display area associated with the device. Whether the display screen is a part of a television, computer, or any other consumer device, the graphical user interface appears on the active area of the display screen. As a result the GUI masks a part of the display screen and the amount of information that can be viewed on the screen is reduced. Ideally the GUI should offer all its features without blocking any part of the display screen. The features should be readily available and …

Inventions On Three Dimensional Gui- A Triz Based Analysis, Umakant Mishra

Umakant Mishra

The graphical user interface has become popular because of its simplicity and user friendliness. The user can do very complex operations through GUI by simple pointer movements. One of its major drawbacks is that it consumes active display area. Every icon, every window and every other GUI element occupies some amount of screen space. It is desirable to display more GUI features within the limited amount of display screen. Adding another dimension to a graphical user interface can yield tremendous benefits such as improving aesthetics, data presentation, screen-space utilization and user friendliness. The user can easily locate the objects in …

Synthesis Design Of Artificial Magnetic Metamaterials Using A Genetic Algorithm, Chien Hsun Chen, P. Y. Chen, H. Wang, J. H. Tsai, W. X. Ni Jan 2008

Synthesis Design Of Artificial Magnetic Metamaterials Using A Genetic Algorithm, Chien Hsun Chen, P. Y. Chen, H. Wang, J. H. Tsai, W. X. Ni

Chien Hsun Chen

In this article, we present a genetic algorithm (GA) as one branch of artificial intelligence (AI) for the optimization-design of the artificial magnetic metamaterial whose structure is automatically generated by computer through the filling element methodology. A representative design example, metamaterials with permeability of negative unity, is investigated and the optimized structures found by the GA are presented. It is also demonstrated that our approach is effective for the synthesis of functional magnetic and electric metamaterials with optimal structures. This GA-based optimization-design technique shows great versatility and applicability in the design of functional metamaterials.


Towards A Business Model For Cellular Network And Telecommunication Operators: A Theoretical Framework, Mutaz M. Al-Debei, Ramzi El-Haddadeh, David Avison Jan 2008

Towards A Business Model For Cellular Network And Telecommunication Operators: A Theoretical Framework, Mutaz M. Al-Debei, Ramzi El-Haddadeh, David Avison

Dr. Mutaz M. Al-Debei

Cellular networks and telecommunications bring major change to the way businesses are conducted. Mobility has become one of the main priorities for users and this has impacted on cellular networks and telecommunication operators (CNTOs). However, entrants into the cellular industry have been confounded primarily by inexistent or weak Business Models (BMs). Designing a BM for a CNTO is complex and requires multiple actors to balance different and often conflicting design requirements. Nevertheless, most research about CNTOs has been technically oriented and has mainly addressed the technological and engineering issues related to their infrastructure. Less attention has been given to the …

Defining The Business Model In The New World Of Digital Business, Mutaz M. Al-Debei, Ramzi El-Haddadeh, David Avison

Dr. Mutaz M. Al-Debei

Recent rapid advances in ICTs, specifically in Internet and mobile technologies, have highlighted the rising importance of the Business Model (BM) in Information Systems (IS). Despite agreement on its importance to an organization’s success, the concept is still fuzzy and vague, and there is no consensus regarding its definition. Furthermore, understanding the BM domain by identifying its meaning, fundamental pillars, and its relevance to other business concepts is by no means complete. In this paper we aim to provide further clarification by first presenting a classification of definitions found in the IS literature; second, proposing guidelines on which to develop …
