TiNi合金不完全相变的温度记忆效应

通过示差扫描量热分析(DSC)研究了预应变及约束条件下TiNi形状记忆合金的温度记忆效应．结果表明，通过变形约束手段，可以大大拓宽TiNi合金的相变温度区间，使得TiNi合金的温度记忆效应能够在一个非常大的温度范围内发挥作用；同时，变形并约束后TiNi合金的温度记忆效应比自由态TiNi合金的温度记忆效应更加准确．分析表明，马氏体与母相界面处的位错以及界面处的弹性自适应过程是可能的温度记忆效应机制。     

Toward Self‐Motivated,Cognitive, Continually Planning Agents

We present a flexible initial framework for defining self‐motivated, self‐aware agents in simulated worlds, planning continuously so as to maximize long‐term rewards. While such agents employ reasoned exploration of feasible sequences of actions and corresponding states, they also behave opportunistically and recover from failure, thanks to their continual plan updates and quest for rewards. Our framework allows for both specific and general (quantified) knowledge and for epistemic predicates such as knowing‐that and knowing‐whether. Because realistic agents have only partial knowledge of their world, the reasoning of the proposed agents uses a weakened closed‐world assumption; this has consequences for epistemic reasoning, in particular introspection. The planning operators allow for quantitative, gradual change and side effects such as the passage of time, changes in distances and rewards, and language production, using a uniform procedural attachment method. Question answering (involving introspection) and experimental runs are shown for our particular agent ME in a simple world, demonstrating the value of continual deliberate, reward‐driven planning. Though the primary merit of agents definable in our framework is that they combine all of the aforementioned features, they can also be configured as single or multiple goal‐seeking agents and as such perform comparably with some recent experimental agents.     

改进的对象间差异度的限制容差关系模型

不完备信息系统不能直接用经典的粗糙集理论来处理,为此,容差关系、非对称相似关系、限制容差关系、限制非对称相似关系、对象间差异度的限制非对称相似关系等扩充的粗糙集模型被相继提出。通过分析这些模型的优点和不足之处,定义了新的对象间差异度,提出了一种改进的对象间差异度的限制容差关系模型,实例结果表明基于所提出模型的划分更精确,更符合实际。     

Territorial targeting in EU private law

In a series of rulings given in the last few years, the Court of Justice of the European Union (EU) has made use of the concept of targeting by a trader of a particular territorial market as a device for determining the scope of European legislation on private law. The concept is of particular importance in the context of trading activities conducted by means of the Internet, though its significance is not confined to such activities. In particular, the European Court has used the concept of targeting for the purpose of restricting the substantive ambit of intellectual property rights created or harmonised by EU legislation. On the other hand, it has avoided use of the concept of targeting in the context of EU legislation allocating jurisdiction between the courts of the Member States, even in respect of disputes involving intellectual property, except where a legislative text specifically invokes such a concept. The instant paper endeavours to review the position as currently established by the European case-law, and to predict the likely further developments.     

Closing the gap between copyright and designs: an age of enlightenment or state of confusion?

The arena of intellectual property encompasses streams that often interrelate and overlap in protecting different aspects of intellectual property. Australian commentators suggest that ‘one of the most troublesome areas in the entire field of intellectual property has been the relationship between copyright protection for artistic works under the Copyright Act 1968 (Cth) and protection for registered designs under the Designs Act 1906 (Cth).’ [McKeough, J., Stewart, A., & Griffith, P. (2004). Intellectual property in Australia (3rd ed.). Chatswood, NSW: Butterworths.] [Ricketson, S., Richardson, M., & Davison, M. (2009). Intellectual property: Cases, materials and commentary (4th ed.). Chatswood, NSW: LexisNexis Butterworths.] This overlap has caused much confusion for both creators of artistic works and industrial designs, as there is an uncertainty of whether protection against infringement is afforded under the Copyright Act 1988 (Cth) or whether the Designs Act 2003 (Cth) will apply. In Australia, there is limited precedent that examines the crossover between copyright and designs. Essentially, the cases that have tested this issue remain unclear as to whether a design applied industrially will invoke copyright protection. The cases demonstrate that there is an inconsistency in this area despite the aims of the new provisions of the Designs Act 2003 (Cth) to close the loopholes between copyright and designs. This paper will discuss and evaluate the relationship between copyright protection for artistic works and protection for registered designs with respect to the Designs Act 2003 (Cth).     

Application of load balancing based on symmetric balanced incomplete block design to random networks

In a load balancing algorithm [O. Lee, M. Anshel, I. Chung, Design of an efficient load balancing algorithm on distributed networks by employing symmetric balanced incomplete block design, IEE Proceedings - Communications 151 (6) (2004) 535-538] based on the SBIBD (Symmetric Balanced Incomplete Block Design), each node receives global workload information by only two round message exchange with traffic overhead, where v is the number of nodes. It is very efficient and works well only when v=p²+p+1 is used for a prime number p. In this paper, we generated a special incidence structure using the SBIBD and then propose a new load balancing algorithm, which executes well for an arbitrary number of nodes. To accomplish this, we add a number of links to nodes in order for each node to receive more than 80% of the workload information by two round message exchange. For performance of our algorithm, we carried out an experiment for the number of nodes, w, which was up to 5000. Traffic overhead is less than in a round and standard deviation of traffic overhead shows that each node has a mostly well-balanced amount of traffic.
