This article describes the rationale for the multiphase creative problem solving process, and reports the findings from an empirical investigation conducted to facilitate the problem solving of managers. The ideational skills of the managers were assessed before and after training in a complete process of creative problem solving, along with their ideational attitudes, creative problem solving style (i.e., generator, conceptualizer, optimizer, or implementor), and evaluative skill (i.e., ability to recognize original ideas). The most important findings indicated that the training had a significant impact on the evaluative accuracy of the managers. They were significantly more accurate in their judgments about original ideas after training, both in their identification of original ideas and their recognition of unoriginal ideas. After training, the managers also gave more solutions and more original solutions to problems. Finally, several variables (e.g., the “preference for active divergence” attitude, and the conceptualizer process style) seemed to moderate the impact of training. Training was therefore effective, with specific effects that can be predicted from pre-training individual differences in attitudes and process style.  相似文献

A new method of stochastic model reduction has recently been introduced by Desai et al. [1], [2]. The stability of the reduced order model has not previously, been considered. In this paper, we show that the stability of the reduced order model follows directly from the results of Pernebo and Silverman [3]. It is also shown that the reduced order model is minimal, in the controllability/observability sense. The relevance of this notion of minimality to stochastic minimality is made clear.  相似文献

We discuss calibration and removal of "vignetting" (radial falloff) and exposure (gain) variations from sequences of images. Even when the response curve is known, spatially varying ambiguities prevent us from recovering the vignetting, exposure, and scene radiances uniquely. However, the vignetting and exposure variations can nonetheless be removed from the images without resolving these ambiguities or the previously known scale and gamma ambiguities. Applications include panoramic image mosaics, photometry for material reconstruction, image-based rendering, and preprocessing for correlation-based vision algorithms.  相似文献

In this paper we present a sound and complete semantics for the monitor concept of C.A.R. Hoare. First a method for specification of monitors, introduced by O.-J. Dahl, is reviewed. This method is based on the relation between the historic sequence of monitor procedure calls and the historic sequence of monitor procedure exits. Based on such specifications and our new monitor semantics we present a method by which it is possible to prove that a concrete monitor is an implementation of an abstract one. In the last part of the paper an axiomatic semantics for systems of concurrent processes and monitors is introduced. The method supports verification by separation of concerns: Properties of the communication to and from each process are proven in isolation by a usual Hoare style axiomatic semantics, while abstract monitors are also specified in isolation by the method reviewed in the first part of the paper. These properties of the components of the system are then used in a new proof rule to conclude properties of the complete system. Stein Gjessing received a Ph.D. (actually a Dr. philos.) from the University of Oslo (Norway) in 1985. Presently he is an Associate Professor at the Institute of informatics, University of Oslo, Norway. Dr. Gjessings research interests are in the area of concurrent and distributed programming, operating systems, formal specification and verification and programming languages.  相似文献

The deep connection between the Burrows–Wheeler transform (BWT) and the so-called rank and select data structures for symbol sequences is the basis of most successful approaches to compressed text indexing. Rank of a symbol at a given position equals the number of times the symbol appears in the corresponding prefix of the sequence. Select is the inverse, retrieving the positions of the symbol occurrences. It has been shown that improvements to rank/select algorithms, in combination with the BWT, turn into improved compressed text indexes.  相似文献

The development of an interface coupling program on personal computers for an analysis software system such as ANSYS, SAP, etc. and an optimization software system, MOST, is presented. By controlling and directing the communications the interface coupler integrates the two programs while retaining their versatility and interactive features. The integrated system is used to solve a numerical example of active noise control for a three-dimensional enclosure, in which an energy density level of control points is minimized by adding the sound source to cancel the unwanted noise. The interface coupling program automates with relatively low cost the iterative process for designing an engineering system, remaining flexible in acoustical modelling and efficient in equation solving. Also, the coupling interface is developed in a general-purpose way so that it can be expanded easily to integrate more analysis software packages of different kinds.  相似文献

This article, first of all, supports the idea that the undeniable process of ICT-based technological convergence implies the social, cultural and business unification of the world of media and culture. The poor performance of the megamerger is a clear indicator of the unstable ground of the convergence hypothesis. Secondly, it argues in favour of cooperation between different expertise, skills and cultures to make multimedia products or to supply multimedia services, instead of creating from scratch a brand new class of hybrid skills and professions. Thirdly, a variety of new possible and realistically achievable professional profiles in cultural industries and institutions are illustrated. Eventually a set of public policies, in the light of a new role for cities and regions, is developed.

This paper describes the development and application of a geometric dimension and tolerance (GD&T) model for use in both design and process planning. The model meets criteria for computability and compatibility with the Y14.5M standard. The model is first used to capture the designers GD&T scheme on a feature based design model, validate its completeness, and then transfer the GD&T to machining features extracted automatically by feature recognition. The model is based on relative degrees of freedom of geometric entities: feature axes, edges, faces and features-of-size. Dimension graphs are created based on the degrees of freedom for each control direction. Datum reference frames and standard tolerance classes are incorporated into the graph. The model allows dimension specification, dimension scheme modification, and dimension scheme validation. A methodology to automatically determine the GD&T of machining volumes obtained by feature recognition is also described.  相似文献

Many have bowed before the recently acquired powers of ‘new technologies’. However, in the shift from tekhnē to tekhnologia, it seems we have lost human values. These values are communicative in nature as technological progress has placed barriers like distance, web pages and ‘miscellaneous extras’ between individuals. Certain values, like the interpersonal pleasures of rendering service, have been lost as their domain of predilection has for many become fully commercially oriented, dominated by the cadence of profitability. Though the popular cultures of the artificial have surged forth to deliver us from the twentieth century, they have enabled some very superfluous dreaming—Man has succumbed to the Godly role of simulating himself and creating other beings. Communication is replaced by machines, services are rendered via many automated devices, procreation has entered the public sphere, robots and entertainment agents educate our youth and mesmerising screen-integrating ‘forms of intelligence’ even think for us. As such, this so-called culture threatens the very values Man constructed in the nineteenth and twentieth centuries to guide himself into the future. But what if the phenomena mentioned just reflect our new values? The author presents an investigation into this cultural shift, its impact on human practices with regards the mind and the body and evokes some pros and cons of generally accepting the ‘Culture of the Artificial’.  相似文献

A few years ago, during a well-attended open Design Automation Conference benchmark forum, a panellist pointed out that “...reporting experimental results is a science and an art. A survey of the literature may reveal a consistent methodology.... Also, we should address the verification of reported results.” In retrospect, the suggestion may have hinted at the vast body of techniques commonly known as experimental design. However, this forum was not ready to expand on the subject. Most search engines currently on the Web return tens of thousands of URLs in response to keyword searches using terms such as experimental design or design of experiments. Few, if any, of these search results point to an evaluation of CAD algorithms. In contrast, the experimental design methodology, pioneered by Fischer during the 1920s in agricultural research, is now firmly established in science and manufacturing. Its application to biomedical research can save lives. Biomedical journals have strict guidelines on how to report experimental results so others may replicate experiments. A URL from a medical school points to a concise illustration of a simple experimental design flow and the terminology used. Adopting the accepted norms of experimental design will give us a scientific method to conduct, verify, and report comparative performance evaluations of CAD algorithms  相似文献

电磁定位具有精度高、速度快和易实现等优点,所以对手术、室内和室外机器人跟踪是一个良好的选择。电磁定位以交变电磁信号作为源信号。交变的电流信号激励发射线圈(信号激励部件)在空间中产生交变的电磁场,感应线圈(信号感应部件)在交变的电磁场中输出频率相同的信号。根据输出信号的幅值和相位信息,我们可以计算出感应线圈相对于发射线圈的位置和方向信息。本文面向机器人定位跟踪,介绍电磁定位系统的原理与实现,包括磁场模型、电磁定位算法与系统软硬件的搭建与实验。本文介绍两种不同的激励模式,分别为分时激励3轴正交发射线圈模式与同时激励2轴正交发射线圈模式,两种模式中的感应线圈均采用3轴正交线圈。实验结果表明,定位系统可以达到1 mm的定位精度。  相似文献
