洪家渡水电站工程高边坡综述

乌江洪家渡水电站坝址河谷深切300余m,硬质岩与软质岩相间分布,岸坡地形陡峻,软弱夹层发育,卸荷、崩塌等物理地质作用强烈。根据坝址地质条件与电站枢纽布置,工程存在:隧洞群进水口同向高边坡整体稳定问题;坝肩开挖、隧洞进出口开挖、厂房开挖及料场开挖等高边坡稳定问题;泄洪冲刷及雾化区1号、2号塌滑体高边坡稳定问题;王家渡堆料场、瓦房寨砂石系统高边坡稳定问题。因此,工程高边坡稳定问题是本工程的主要工程问题之一,但通过参建各方共同努力,本工程高边坡处理都取得了圆满成功。     

Quality of Service in VoIP Communication

The focus of this paper lies in the practical aspects of voice over IP communication. VoIP configurations in the H.323 standard will be presented briefly. Following that, the fundamental protocol procedure of H.323 communication will be briefly explained. A further part of the paper will address the subject QoS (quality of service), and present the common measurement methods used in QoS. Results gained from experiments conducted in a VoIP environment will then follow. The investigations concentrate primarily on the load behavior of voice packets in relation to important parameters of this service. The results obtained are presented and evaluated in diagrams. The paper concludes with a summary.     

Requirements engineering in health care: the example of chemotherapy planning in paediatric oncology

Health care is characterized by highly complex processes of patient care that require unusual amount of communication between different health care professionals of different institutions. Sub-optimal processes can significantly impact on the patient’s health, increase the consumption of services and resources and in severe cases can lead to the patient death. For these reasons, requirements engineering for the development of information technology in health care is a complex process as well: without constant and rigorous evaluation, the impact of new systems on the quality of care is unknown and it is possible that badly designed systems significantly harm patients. To overcome these limitations, we present and discuss an approach to requirements engineering that we applied for the development of applications for chemotherapy planning in paediatric oncology. Chemotherapy planning in paediatric oncology is complex and time-consuming and errors must be avoided by all means. In the multi-hospital/multi-trial-centre environment of paediatric oncology, it is especially difficult and time-consuming to analyse requirements. Our approach combines a grounded theory approach with evolutionary prototyping based on the constant development and refinement of a generic domain model, in this case a domain model for chemotherapy planning in paediatric oncology. The prototypes were introduced in medical centres and final results show that the developed generic domain model is adequate.
