论香水容器造型设计的模拟性

论述香水容器造型设计中的模拟性,是指依照客观形象进行描绘和塑造,一般表现在器物的立体造型上,即模拟各种生物形象。模拟不等于复制,模拟则具有较多的主观创造因素,是对物体形象的再创造。     

The meaning of silence

Silence resides in the gaps between the known islands of explicit knowledge. Rather than expecting to build systems with complete information, we take a human-centred approach. Individual citizens need to be active, engage in dialogue and be aware of the importance of tacit knowledge. As societies, we recognise the incompleteness and inconsistency of our discourse.

Internal and external influences on social networking site usage in Thailand

The purpose of the study is to investigate internal and external factors influencing the use of social networking sites (SNSs) in Thailand. Overall (N = 451) participated in this study. Survey research was employed to examine the interrelationships and differences among a set of variables. The results showed that both internal and external factors affecting the use of SNSs and SNS motivation. External factors, particularly media and significant others were more influential than internal factors to predicting time spent on SNSs. People who were influenced by media and significant others would be more likely to spend more time using SNSs and Facebook. SNS motivation led to different SNS use. In particular, those who were motivated to use SNS for relaxation would spend more time using Facebook. In addition, the findings indicated that females would spend more time using YouTube, Twitter, and Hi5 than males. Moreover, females tended more to use SNSs to maintain their friendship than did males.     

Intelligent facial emotion recognition and semantic-based topic detection for a humanoid robot

Automatic perception of human affective behaviour from facial expressions and recognition of intentions and social goals from dialogue contexts would greatly enhance natural human robot interaction. This research concentrates on intelligent neural network based facial emotion recognition and Latent Semantic Analysis based topic detection for a humanoid robot. The work has first of all incorporated Facial Action Coding System describing physical cues and anatomical knowledge of facial behaviour for the detection of neutral and six basic emotions from real-time posed facial expressions. Feedforward neural networks (NN) are used to respectively implement both upper and lower facial Action Units (AU) analysers to recognise six upper and 11 lower facial actions including Inner and Outer Brow Raiser, Lid Tightener, Lip Corner Puller, Upper Lip Raiser, Nose Wrinkler, Mouth Stretch etc. An artificial neural network based facial emotion recogniser is subsequently used to accept the derived 17 Action Units as inputs to decode neutral and six basic emotions from facial expressions. Moreover, in order to advise the robot to make appropriate responses based on the detected affective facial behaviours, Latent Semantic Analysis is used to focus on underlying semantic structures of the data and go beyond linguistic restrictions to identify topics embedded in the users’ conversations. The overall development is integrated with a modern humanoid robot platform under its Linux C++ SDKs. The work presented here shows great potential in developing personalised intelligent agents/robots with emotion and social intelligence.     

Encrypted Books: Mysteries that Fill Hundreds of Pages

Abstract

The cryptology literature and other sources mention several dozen books that are entirely or partially encrypted. However, a systematic treatise about this issue has never been made. This article aims to close this gap. The author has assembled a list of encrypted books that contains 41 entries, so far. Based on this list, an overview on encrypted books is given. Encrypted books are classified according to criteria like purpose, solved/unsolved, encryption method, and creation time. Numerous open research questions are identified. Finally, it is a goal of this article to ask readers for additional information about the books on the list and for encrypted books that are still missing.     

Deriving real-time action systems in a sampling logic

Action systems have been shown to be applicable for modelling and constructing systems in both discrete and hybrid domains. We present a novel semantics for action systems using a sampling logic that facilitates reasoning about the truly concurrent behaviour between an action system and its environment. By reasoning over the apparent states, the sampling logic allows one to determine whether a state predicate is definitely or possibly true over an interval. We present a semantics for action systems that allows the time taken to sample inputs and evaluate expressions (and hence guards) into account. We develop a temporal logic based on the sampling logic that facilitates formalisation of safety, progress, timing and transient properties. Then, we incorporate this logic to the method of enforced properties, which facilitates stepwise refinement of action systems.     

基于RIA技术的在线试衣间系统的设计

目前,大多数服装网上商店只提供服装照片供消费者参考,由于缺乏一个直观的试衣效果,使得较多的顾客对购买的商品不满意,从而导致退换纠纷。针对这一现状,文中基于RIA技术,利用HexBuilder工具和Action Script语言,设计开发了一个基于B／S架构的在线试衣间原型系统。该系统主要完成了在线试衣、人物更换、分享展示和购物车等模块。在线试衣问系统能够增强用户体验,使得消费者对衣服有了更直观具体的了解,从而能极大改善网上购衣的现状,具有较高的实用价值。     

Asynchronous and distributed process improvement: the role of collaborative technologies

Abstract. The recent proliferation of low-cost computer networks has driven the development of a new type of organization, in which geographical and time constraints to collaboration among process teams have been gradually removed. As these organizations have to cope with a fast pace of change, they rely increasingly on distributed and asynchronous process improvement (PI) groups to redesign their processes. Yet little is known about the effects of asynchronous group support systems (GSSs) on PI groups. We investigate the effects of asynchronous GSSs on PI groups through a two-stage action research study of 38 such groups in three organizations, one in Brazil and two in New Zealand, over 4 years and 4 months. Different PI groups voluntarily conducted all, part or none of their communication through an e-mail conferencing (EC) tool. The research suggests that EC support causes a decrease in the organizational costs associated with PI groups, which, combined with an increase in the number of possible simultaneous PI groups, generates an increase in overall organizational PI efficiency. The research also suggests a neutral overall effect of EC support on PI group outcome quality. Two explanatory causal models summarizing these effects are developed, and implications for research and industry practice are discussed.
