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

The application of directional antennas in wireless ad hoc networks brings numerous benefits, such as increased spatial reuse and mitigated interference. Most MAC protocols with directional antennas are based on the RTS/CTS mechanism which works well in wireless ad hoc networks using omni-directional antennas. However, RTS/CTS frames cannot mitigate the interference completely. Besides, they also contribute a lot to the performance overhead. This paper studies the problem from a new perspective. We have found that the transmission success probability under directional transmission and directional reception is quite high when the antenna beamwidth is quite narrow. Motivated by the analytical results, …

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
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
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 …

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
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
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
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 …

Digital rights management allows information owners to control the use and dissemination of electronic documents via a machine-readable licence. This paper describes the design and implementation of a system for creating and enforcing licences containing location constraints that can be used to restrict access to sensitive documents to a defined area. Documents can be loaded onto a portable device and used in the approved areas, but cannot be used if the device moves to another area. Our contribution includes a taxonomy for access control in the presence of requests to perform non-instantaneous controlled actions.

A Reservation-Based Extended Transaction Protocol, Wenbing Zhao, Louise E. Moser, P. Michale Melliar-Smith
Electrical and Computer Engineering Faculty Publications
With the advent of the new generation of Internet-based technology, in particular, web services, the automation of business activities that are distributed across multiple enterprises becomes possible. Business activities are different from traditional transactions in that they are typically asynchronous, loosely coupled, and long running. Therefore, extended transaction protocols are needed to coordinate business activities that span multiple enterprises. Existing extended transaction protocols typically rely on compensating transactions to handle exceptional conditions. In this paper, we identify a number of issues with compensation-based extended transaction protocols and describe a reservation-based extended transaction protocol that addresses those issues. Moreover, we define …

Optimization In Multi-Agent Systems : Structures And Procedures, Ingo Stengel
Optimization In Multi-Agent Systems : Structures And Procedures, Ingo Stengel
Theses
The main advantage for the use of agent technology is in the capacity of agents to represent the interests of individual entities and to act autonomously on their behalf. In multi-agent systems this involves communication, coordination and negotiation.
The focus of this dissertation is to find ways to optimize multi-agent systems at different levels by taking into consideration their structure and the procedures used. As optimization depends to a large extent on the problem to be solved, group forming scenarios, in which self-interested agents compete to form and join groups, have been selected here for consideration. Optimization issues are discussed …

Computational Modeling & Simulation Engineering Faculty Publications
Net-centric services shall be designed to collaborate with other services used within the supported Community of Interest (COI). This requires that such services not only be integratable on the technical level and interoperable on the implementation level, but also that they are composable in the sense that they are semantically and pragmatically consistent and able to exchange information in a consistent and unambiguous way.
In order to support Command-and-Control with Composable Net-centric Services, the human-machine interoperation must be supported as well as the machine-machine interoperation. This paper shows that techniques of computer linguistic can support the human-machine interface by structuring …

Mitigation Of Control Channel Jamming Under Node Capture Attacks, Patrick Tague, Mingya Li, Radha Poovendran
Patrick Tague
Availability of service in many wireless networks depends on the ability for network users to establish and maintain communication channels using control messages from base stations and other users. An adversary with knowledge of the underlying communication protocol can mount an efficient denial of service attack by jamming the communication channels used to exchange control messages. The use of spread spectrum techniques can deter an external adversary from such control channel jamming attacks. However, malicious colluding insiders or an adversary who captures or compromises system users are not deterred by spread spectrum, as they know the required spreading sequences. For …

On The Capacity Of Multi-Channel Wireless Networks Using Directional Antennas, Hong-Ning Dai, Kam-Wing Ng, Raymond Chi-Wing Wong, Min-You Wu
Hong-Ning Dai
The capacity of wireless ad hoc networks is affected by two key factors: the interference among concurrent transmissions and the number of simultaneous transmissions on a single interface. Recent studies found that using multiple channels can separate concurrent transmissions and greatly improve network throughput. However, those studies only consider that wireless nodes are equipped with only omnidirectional antennas, which cause high collisions. On the other hand, some researchers found that directional antennas bring more benefits such as reduced interference and increased spatial reuse compared with omnidirectional antennas. But, they only focused on a single-channel network which only allows finite concurrent …

Electrical power systems play a critical role in spacecraft and aircraft. This paper discusses our development of a diagnostic capability for an electrical power system testbed, ADAPT, using probalistic techniques. In the context of ADAPT, we present two challenges, regarding modelling and real-time performance, often encountered in real-world diagnostic applications. To meet the modelling challenge, we discuss our novel high-level specification language which supports auto-generation of Bayesian networks. To meet the real-time challenge, we compile Bayesian networks intro arithmetic circuits. Arithmetic circuits typically have small footprints and are optimized for the real-time avionics systems found in spacecraft and aircraft. Using …
