自适应设计在电子医疗的应用研究

自适应网页设计是一种目前国内外最新流行的网页设计技术,通过对网页页面的大小调整、重新布局等来满足用户来自不同大小的手持移动设备,如笔记本电脑、平板电脑、智能手机等对网页直接实时访问的需求。在能给用户提供理想的网页视觉体验前提下,大大减少了针对于小屏幕移动设备的网页重新开发成本。文中通过总结现有的国外自适应网页设计方法,提出了一个网页的基本自适应框架,并且基于该框架设计并实现了一整套具有网页自适应功能的电子医疗系统。系统测试表明,较普通不具有自适应功能的网页,利用该框架的自适应网页在页面读取速度与访问时间上有显著的提高。

Business process improvement using multi-objective optimisation

Business process redesign and improvement has become an increasingly attractive subject in the wider area of business process intelligence. Although there have been many attempts to establish a business process redesign framework, there is little work on the actual optimisation of business processes with given objectives. Furthermore, most of the attempts to optimise a business process are manual and do not involve a formal automated methodology. This paper proposes a process improvement approach for automated multi-objective optimisation of business processes. The proposed framework uses a generic business process model that is formally defined. The formal definition of business processes is necessary to ensure that the optimisation will take place in a clearly defined, repeatable and verifiable way. Multi-objectivity is expressed in terms of process cost and duration as two key objectives for any business process. The business process model is programmed and incorporated into a software optimisation platform where a selection of multi-objective optimisation algorithms can be applied to a business process design. This paper outlines a case study of business process design that is optimised by the state-of-the-art multi-objective optimisation algorithm NSGA2. The results indicate that, although business process optimisation is a highly constrained problem with fragmented search space, a number of alternative optimised business processes that meet the optimisation criteria can be produced. The paper also provides directions for future research in this area.

Intelligence and mobility for BT’s next generation networks

In common with the majority of service providers today, BT currently implements services and applications with a disparate set of intelligence components, which have been provided over a number of years. It is a key belief that a unified intelligence architecture, implemented as software components in centralised data centres, is essential to hit the key strategic requirements of improved customer experience, increased speed to market and cost reduction. Unification of network and user client intelligence is key. BTs proposed multiservice network and intelligence platform needs to support fixed, mobile and mobility services as well as the broad range of communications applications. The intelligence platform needs to provide the necessary reuse of common capabilities, e.g. authentication, to support these services and applications. Enabling applications to be delivered in co-operation with partners, as well as providing enterprise solutions for specific organisations, is commercially important. This paper describes the architecture for this major change for intelligence in the BT network.     

Operational risk management with real-time business intelligence

Operational risk is a function of the complexity of the business and the environment that the business operates in. Such complexities increase as the business or the environment become more dynamic, i.e. where change is a permanent feature and a factor to build into the management of the business. The key question that arises is how do businesses respond to such changes today and, if the nature of the business and the environment is becoming more and more dynamic, what actions can businesses take to predict and prepare for change. Viewed in this manner, operational risk becomes very closely related to the operational performance of the enterprise because it can be considered as dealing with changes that have a negative impact on the operational objectives. It is vital for enterprises to understand in real time how they are performing, and where on the spectrum of operational risk they are positioned. To accomplish this, it is essential to have a system for establishing the status of a business at any moment in time in relation to its performance objectives. This is the role of real-time business intelligence (RTBI), without which operational risk management could be out of date, or in some cases out of synchronisation with the business cycle, with serious consequences. This paper discusses the cornerstones of RTBI and demonstrates how these are also essential elements of an effective operational risk management framework.

Web—mail跨站漏洞检测技术研究

Web程序通常在页面中嵌入使用JavaScrip脚本来实现检测动态客户端行为。这些脚本在用户浏览器的上下文中被执行。为了防范恶意的JavaScript脚本,浏览器可以使用一套沙盒机制,使脚本只能访问到自己所在网站域的资源。如果用户被诱骗至一个中间的、受信任的网站,然后从该网站下载恶意脚本,那么此套安全机制就失效了。文章呈现了一套Web邮件跨站代码检测系统模型,该模型能满足高效率、优性能下的完整代码测试需求。根据设计需求,文章实现了Web邮件跨站脚本检测系统。最后,对系统的测试结果表明：系统具有一定的可行性与实用性。

TRack others if you can: localized proximity detection for mobile networks

For a set of mobile users with designated friendship relations, it is a recurring issue to keep track of whether some friends appear in the vicinity of a given user. While both distributed and centralized solutions for proximity detection have been proposed, the cost metrics for evaluating these proposals are always based on counting the number of message (e.g., query or update) exchanges. However, as mobile users often rely on wireless networks to maintain their connectivity, the cost incurred by any message passing is strongly affected by the distance between the sender and receiver. In this paper, we propose TRack Others if You can (TROY) as a novel distributed solution for proximity detection. Extending the principle of spatial tessellations, TROY incurs only localized message exchanges and is thus superior to existing proposals in terms of more realistic cost metrics that take into account the actual energy consumption of message passing. Moreover, our spatial tessellations inspired analytical framework allows for a meaningful comparison with an existing work. Finally, we use extensive experiments to validate the efficiency of TROY.
