The Ancient Theory of Mind

Happiness and suffering are both the result of two factors combined: the situation in which one is placed and our consciousness of it. Happiness is not only of personal importance, it is also a necessary factor for ensuring peace in society. Therefore it is important to know the two possible ways for the pursuit of happiness: applied science, which focuses on how situations can be controlled, and spirituality, which focuses on developing the various types of consciousness one can have. The notion of purified consciousness is formulated in terms of psychology, neurophysiology, logic and meditative practice. Received February 2002 / Accepted in revised form March 2002

The Modular Structure of Complex Systems

This paper discusses the organization of software that is inherently complex because of very many arbitrary details that must be precisely right for the software to be correct. We show how the software design technique known as information hiding, or abstraction, can be supplemented by a hierarchically structured document, which we call a module guide. The guide is intended to allow both designers and maintainers to identify easily the parts of the software that they must understand, without reading irrelevant details about other parts of the software. The paper includes an extract from a software module guide to illustrate our proposals.     

图像方向性在空域和频域中的特性研究

文章研究了图像的方向性在空域和频域分析中的不同特性。首先,建立了图像的空域模型和频域模型,对两者的特性进行了数学分析,并且通过一定的仿真实验进行了验证。结果表明,图像的空域方向性和频域方向性之间存在着确定的关联性。这一特性在图像的频域分析中有着至关重要的作用。     

The New Mind: thinking beyond the head

Throughout much of the modern period, the human mind has been regarded as a property of the brain and therefore something confined to the inside of the head—a view commonly known as ‘internalism’. But recent works in cognitive science, philosophy, and anthropology, as well as certain trends in the development of technology, suggest an emerging view of the mind as a process not confined to the brain but spread through the body and world—an outlook covered by a family of views labelled ‘externalism’. In this paper, we will suggest there is now sufficient momentum in favour of externalism of various kinds to mark a historical shift in the way the mind is understood. We dub this emerging externalist tendency the ‘New Mind’. Key properties of the New Mind will be summarised and some of its implications considered in areas such as art and culture, technology, and the science of consciousness.

The Role of Modular Robotics in Mediating Nonverbal Social Exchanges

This paper outlines the use of modular robotics to encourage and facilitate nonverbal communication during therapeutic intervention in dementia care. A set of new socially interactive modular robotic devices called rolling pins (RPs) has been designed and developed to assist the therapist in interacting with dementia-affected patients. The RPs are semitransparent plastic tubes that are capable of measuring their orientation and the speed of their rotation; at a local level, they have three types of feedback: red, green, and blue light, sound, and vibration. The peculiarity of the RPs is that they are able to communicate with each other or with other devices equipped with the same radio communication technology. The RPs are usually used in pairs, as the local feedback of an RP can be set depending not only on its own speed and orientation but also on the speed and the orientation of the peer RP. The system is not used as a therapeutic tool per se but as a facilitator and a mediator of social dynamics during normal therapy to counteract social isolation that can result in dementia through the loss of social skills. An experiment is reported that shows that by using the RPs, the patients participated in the activity by coordinating their behavior with the therapist and imitating the same interaction patterns generated by the therapist.

The Role of Domain Expenence in Software Design

A designer's expertise rests on the knowledge and skills which develop with experience in a domain. As a result, when a designer is designing an object in an unfamiliar domain he will not have the same knowledge and skills available to him as when he is designing an object in a familiar domain. In this paper we look at the software designer's underlying constellation of knowledge and skills, and at the way in which this constellation is dependent upon experience in a domain. What skills drop out, what skills, or interactions of skills come forward as experience with the domain changes? To answer the above question, we studied expert designers in experimentally created design contexts with which they were differentially familiar. In this paper we describe the knowledge and skills we found were central to each of the above contexts and discuss the functional utility of each. In addition to discussing the knowledge and skills we observed in expert designers, we will also compare novice and expert behavior.
