Dynamic Power Saving via Least-Square Self-Tuning Regulator in the Virtualized Computing Systems

In recent years,power saving problem has become more and more important in many fields and attracted a lot of research interests.In this paper,the authors consider the power saving problem in the virtualized computing system.Since there are multiple objectives in the system as well as many factors influencing the objectives,the problem is complex and hard.The authors will formulate the problem as an optimization problem of power consumption with a prior requirement on performance,which is taken as the response time in the paper.To solve the problem,the authors design the adaptive controller based on least-square self-tuning regulator to dynamically regulate the computing resource so as to track a given reasonable reference performance and then minimize the power consumption using the tracking result supplied by the controller at each time.Simulation is implemented based on the data collected from real machines and the time delay of turning on/off the machine is included in the process.The results show that this method based on adaptive control theory can save power consumption greatly with satisfying the performance requirement at the same time,thus it is suitable and effective to solve the problem.

xmlTRAM +:an XML-based tool for management of requirements and architectures

Information systems have been increasingly used in all aspects of organization's business activities. These systems will inevitably evolve over time. The system development knowledge is a key to the understanding and evolution of these systems. As such, the system development knowledge is a part of the corporate knowledge that needs to be properly managed. In particular, the system requirements and architecture design are the most important system development knowledge. An XML-based tool for managing system requirements and architectures is introduced. The use of the XML technology allows the system requirements and architectures to be easily shared across the organization. The issues discussed include a conceptual model, a logical model and a physical model for the management of system requirements and architectures. In fact, this three-step development process provides a typical methodology for the development of XMLbased systems.

Fostering Design Culture Through Cultivating the User-Designers' Design Thinking and Systems Thinking

In this paper, the essence of design thinking and systems thinking is reviewed, analyzed, and synthesized. Although there are many valuable schools of systems thinking, I focus on both Banathy's and Senge's since there are design spirit embedded in their systems thinking. I attempt to grasp the spirit of Banathy's systems models and the essence of Senge's systems thinking, incorporating them into my design inquiry. I propose adopting an enlightened, transformative design approach in order to enhance the revolution of the public's inner and outer systems through collaborative design engagement. It is expected that by utilizing the transformative design approach, the public or user–designers could gain the necessary skills to envision their own learning, assume responsibility for designing their own learning environments, and systematically reflect upon their habitual thinking and actions. Ultimately, the user-designers would be able to transform their model-driven or theory-driven approaches to systems application into a cultural approach to the cultivation of systems thinking and design thinking. Indeed, design thinking, as well as contemporary systems thinking are two powerful wings to make us fly in the capacious learning world of the 21st century.     

Repositing Thinking for Future Social Systems Design: In Tribute to Bela H. Banathy and His Inspiration of the Fuschl Conversations

Contemporary systems activity can be divided into that stressing feasible and practical short-term measures, and that which is more ideal-aware, focussed on mid-longer term futures, and typically involving on-going community or social systems design. The paper highlights the key differences in approach, but then invites closer collaboration in the cause of the possible contribution that systems thinking could make for a longer term future, with Y3K (Year 3000) as a metaphor for this. This analysis, which derives from work undertaken at Asilomar 1995 and Fuschl conversations in 2000 and 2002, finds that contemporary social system design, which is driven by western culture and is action-oriented, needs adaptation before it could contribute to greater future global harmony. A truly comprehensive systems design process must accommodate a wide range of possible parameters in terms of culture, and appreciation of time and progress. An emerging paradigm as basis for thinking and engaging in social systems design work of the future is offered, which also has relevance to general systems practice.
