正确理解和运用避碰规则确保船舶航行安全

1972年国际海事组织颁布了《国际海上避碰规则》,简称《规则》。该规则的颁布主要是用于指导航行中的各类船舶在海上的航行安全,是船舶在海上航行生产中重要的法律法规,是船舶在海上航行过程中工作人员必须遵守和重视的航海规则。航海驾驶人员在船舶航行过程中,要对规避规则深入学习,牢固掌握规则中的各项法条与要求,要对规则有正确的理解,严格遵守。在航行过程中,安全无小事,船舶安全保障是海上航行中的首要任务也是必要任务。通过分析近几年船舶航行的相关碰撞事故,发现造成事故的原因除了客观的、不可抗的因素外,主要是人为原因造成的主观因素,对于这种情况,必须双管齐下,一方面要加强船员技术水平的培训,另一方面加强船员的责任心与使命感的教育,加强航行安全教育,改变懒散随意的工作作风,从源头上杜绝人为因素造成的相关船舶碰撞事故。

Multiple stakeholders and middle managers: the role of the hotel financial controller

This article explores the key characteristics of the specific stakeholders for one type of middle manager, the hotel financial controller. Eleven semi-structured interviews among financial personnel showed that although some owners require on-going profits and have high expectations of middle managers, others may take a more long-term view and be less demanding. Head offices provide systems and services for the unit, but a lack of efficiency and strategic planning affects the ability of managers to do their job. The middle manager must take a proactive intrapreneurial approach in communicating and implementing corporate strategic decisions within the unit and in managing the multiple stakeholders, but in return requires more guidance, resources and support from senior management.     

基于FPGA的交通灯控制器的设计

本系统是以Alters 公司的FPGA,ACEX1K系列 EPlK30TC144-3为核心控制器,利用FPGA芯片完成了十字路口交通灯控制器的设计.该系统主要由两个部分组成:硬件部分和控制部分.控制部分核心是用VHDL语言实现了基于状态机的交通灯控制器,还包括分频模块和显示控制模块.该系统可以实现十字路口双向小于99秒的倒计时及双向红绿灯的控制,显示输出使用数码管和LED灯实现.     

基于神经网络的混沌系统滑模同步控制器设计

针对两个混沌系统,论文设计了基于RBF神经网络的滑模同步控制器.同步误差系统的扰动由非线性不确定项和外部扰动组成.基于RBF神经网络,设计了扰动观测器,并给出跟踪扰动变化的校正算法.根据扰动观测器的输出设计了同步观测器.该同步控制器可使误差系统稳定到零,并消除系统的不确定扣外部扰动.最后,仿真算例验证了同步控制器的有效性.     

外置式电子调速器在进口道依茨柴油机上的应用

一、引言某船用辅机采用了进口道依茨（德国）BF6L913C风冷柴油机作为船用发电机组的原动机。规范（技术规格书）要求，稳态调速率和转速波动率的指标为：稳态调速率≤5％．转速波动率±0．5％。经反复调试和测试。在50％、75％负载时，如稳态调速率达到5％，则转速波动率最高达士0．92％：若要将转速波动率≤±O．5％，则稳态调速率达7-8％。

Brexit and its economic consequences

As the formal process of Brexit has already started, there is much uncertainty about Brexit's impacts on Britain's social, political and economic future. This paper examines the economic impact. After briefly discussing some significant EU treaties that serve as the background materials, it presents the key arguments advocated by the leave and remain camps. The economic impact depends critically on the negotiation outcomes. Aside from the debate on the divorce costs, there are numerous issues that must be negotiated, such as immigration, trade in goods, services, agriculture, fisheries and financial regulations. We discuss various scenarios of possible new trade regimes, resulting in different impacts on the UK economy. With each side having its bargaining chips to play, the trade‐offs between “give and take” in the negotiation game are analysed. Considering various strategic options, this paper urges rationality and cooperation, especially weighing both sides’ entwined economic interests, in addition to their mutual security, defence, environmental and world concerns. The potential gains and losses in the event where the UK contemplates new trade arrangements with the non‐EU countries are analysed in the Appendix .
