With the aid of sophisticated computer software and advanced digital printing machines, happening colour allows images of considerable complication and intricacy to be designed and produced in modern fabric design by various arrangement of printing colours, which also allows further shifts of colour emphasis of the different visual and psychogenic recept.展开更多

Compared with strong happened-before （SHB） and weak happened- before （WHB）, LSHB supports keeping-read-result and ensures definite sufficiency of testing. Equivalence partitioning the set of SYN-sequences based on LSHB can efficiently reduce the number of testing SYN-sequences. The case studies prove that LSHB has high practicability.展开更多

Although HMM itself is simple, some complex axioms have to be introduced in JMM to prevent the causality loop, which causes absurd out-of-thin-air reads that may break the type safety and se- curity guarantee of Java. The resulting JMM is complex and difficult to understand. It also has many anti-intuitive behav- iors, as demonstrated by the ＂ugly examples＂ by Aspinall and ~ev6~ [1]. Furthermore, HMM （and JMM） specifies only what execution traces are acceptable, but says nothing about how these traces are generated. This gap makes it difficult for static reasoning about programs. In this paper we present OHMM, an operational variation of HMM. The model is specified by giving an operational semantics to a language running on an abstract machine de- signed to simulate HMM. Thanks to its generative nature, the model naturally prevents out-of-thin-air reads. On the other hand, it uses a novel replay mechanism to allow instruc- tions to be executed multiple times, which can be used to model many useful speculations and optimization. The model is weaker than JMM for lockless programs, thus can accom- modate more optimization, such as the reordering of inde- pendent memory accesses that is not valid in JMM. Program behaviors are more natural in this model than in JMM, and many of the anti-intuitive examples in JMM are no longer valid here. We hope OHMM can serve as the basis for new memory models for Java-like languages.展开更多

Even at the World Expo in Shanghai, the much-revered Polish musician is too important to be ignored. To celebrate the maestro, the Poland Pavilion has prepared a series of events to honor the bicentennial celebration of Chopin’s birth. On May 8, Slawomir Majman, Commissioner General of the Polish Section of World Expo 2010, sat down with Beijing Review reporter Hu Yue to discuss the planned events and share his views on Chopin’s music.展开更多

文摘This paper defines a new relation--little strong happened-before（LSHB） and presents the algorithm for LSHB. Compared with strong happened-before （SHB） and weak happened- before （WHB）, LSHB supports keeping-read-result and ensures definite sufficiency of testing. Equivalence partitioning the set of SYN-sequences based on LSHB can efficiently reduce the number of testing SYN-sequences. The case studies prove that LSHB has high practicability.

文摘在未来20多年中发达国家经济面临的主要问题不是经济学和技术,也不是劳动力过剩,而是日益严重的人口的老龄化造成的劳动力不足。以美国为例,即使当前出生率异想天开地上升,也要等到25年后才能诞生一批新的劳动力。这种“The future that has。already happened”势必造成退休年龄推迟、世界经济强国的地位不稳和知识型工人需求剧增等问题。
