Design-Side Considerations: A Reaction To Duem, Robert B. K. Brown
Design-Side Considerations: A Reaction To Duem, Robert B. K. Brown
Faculty of Engineering and Information Sciences - Papers: Part A
Evaluation of a system's usability is a difficult task, but a new method, DUEM, addresses several of the issues. Any evaluation conducted after the fact however has limited effect, so further work is required at the design end of the lifecycle. Early-Phase elicitation tools, such as i*, may form the basis for new design tools which simplify software development, improve usability and ensure greater system success. Informing such design tools with the principles of the latest Activity Theory-based usability evaluation methods, such as DUEM should facilitate easier testing. As an added benefit, such a design method can form the first …
Placement And Penetration Of Distributed Generation Under Standard Market Design, Ashish Agalgaonkar, S V. Kulkarni, S A. Khaparde, S A. Soman
Placement And Penetration Of Distributed Generation Under Standard Market Design, Ashish Agalgaonkar, S V. Kulkarni, S A. Khaparde, S A. Soman

Distributed Generation (DG) can help in reducing the cost of electricity to the costumer, relieve network congestion and provide environmentally friendly energy close to load centers. Its capacity is also scalable and it provides voltage support at distribution level. Hence, DG placement and penetration level is an important problem for both the utility and DG owner. The cost of electricity as a commodity depends upon market model. The restructured power markets are slowly maturing with standardizations like Standard Market Design (SMD). The key feature of SMD is the Locational Marginal Pricing (LMP) scheme. This paper examines placement and penetration level …
Design And Implementation Of A Content Filtering Firewall, Rongbo Du, Rei Safavi-Naini, Willy Susilo
Design And Implementation Of A Content Filtering Firewall, Rongbo Du, Rei Safavi-Naini, Willy Susilo
Faculty of Engineering and Information Sciences - Papers: Part A
A firewall is a system for enforcing access control policy between two networks and is one of the most important measures to protect against network attacks. Firewalls traditionally protect the internal network from outside threats. But there has been increasing need for preventing the misuses of the network by the internal users which most previous firewalls overlook. In this paper, we propose a method of adding content filtering functionality to the firewall and describe its implementation. We also show a new attack that combines JAVA Applet and XML to get around the content filtering firewall, hence showing the need for …
Limitations Of Current Design Procedures For Steel Members In Space Frames, Lip H. Teh
Limitations Of Current Design Procedures For Steel Members In Space Frames, Lip H. Teh
Faculty of Engineering and Information Sciences - Papers: Part A
The use of more advanced methods of analysis to design steel frames may lead to substantial material savings, in addition to simplicity in the design procedures. However, these benefits do not yet appear to be a powerful incentive for many structural engineers to abandon the familiar linear elastic analysis (LEA) based design procedures, even when dealing with steel structures that are not regular rectangular frames. This paper uses a heuristic example to demonstrate the serious limitations of the LEA based design procedures, whether alignment charts or system buckling analysis is used to determine the effective lengths of the compression members. …
Toward A Heuristic Optimum Design Of Rolling Schedules For Tandem Cold Rolling Mills, Dadong Wang, A Kiet Tieu, Friso Deboer, B Ma, W. Y. Daniel Yuen
Toward A Heuristic Optimum Design Of Rolling Schedules For Tandem Cold Rolling Mills, Dadong Wang, A Kiet Tieu, Friso Deboer, B Ma, W. Y. Daniel Yuen
Faculty of Engineering and Information Sciences - Papers: Part A
Scheduling for tandem cold mills refers to the determination of inter-stand gauges, tensions and speeds of a specified product. Optimal schedules should result in maximized throughput and minimized operating cost. This paper presents a genetic algorithm based optimization procedure for the scheduling of tandem cold rolling mills. The optimization procedure initiates searching from a logical staring point - an empirical rolling schedule - and ends with an optimum cost. Cost functions are constructed to heuristically direct the genetic algorithm's searching, based on the consideration of power distribution, tension, strip flatness and rolling constraints. Numerical experiments have shown that the proposed …
