矿山地质环境保护研究综述

针对矿区地质环境保护问题,通过分析大量有关文献并结合实践研究,综述了国内外有关矿山开采制度、矿区环境评价与监测技术、矿区地灾防控与生态修复技术等方面的研究进展。对比分析发现:国外矿山地质环境保护着眼微观层面对土壤、水质等方面的修复,而我国矿山地质保护绝大多数尚停留在工程治理层面,法律保障、矿山恢复保证金、矿区绿色复垦技术是现有研究的薄弱环节。因此建议矿区地质灾害保护研究中应高度重视矿山地质环境保护政策、矿山灾变机理、矿山防灾与生态修复技术、矿山地质环境监测预警应急方法、系统与设备等方面,并解读了各研究方向主要思路。研究成果对推动我国矿山地质环境减灾理论研究与防治工程实践具有积极意义。     

Telerobot-enabled HUB-CI model for collaborative lifecycle management of design and prototyping

The HUB-CI model is investigated in a telerobotic system in a client/server network to manage the lifecycle of engineering design and prototyping. The purpose of this platform is to support collaborative engineering design and proof of concept to enhance distributed team collaboration and resource utilization. The suggested platform is exemplified in two collaboration support tools and a physical prototyping platform. Structured Co-Insight Management is developed to support innovative idea exchanges and the consensus decision-making during the design process. Conflict/error detection management helps preventing conflicts and errors during the lifecycle of design and development. Physical collaboration over the network occurs when a team controls the telerobot operation during prototyping and testing in design cycles. A pilot system is implemented with a group project for the design of an electronic circuit (including both hardware and software designs). The functional assessment method is used to compare this platform to other collaborative design tools. The system presented offers unique qualitative advantages as an integrated collaboration support system.

A Progressive Deployment Strategy for Cooperative Adaptive Cruise Control to Improve Trafc Dynamics

Cooperative adaptive cruise control(CACC)vehicles are intelligent vehicles that use vehicular ad hoc networks(VANETs)to share trafc information in real time.Previous studies have shown that CACC could have an impact on increasing highway capacities at high market penetration.Since reaching a high CACC market penetration level is not occurring in the near future,this study presents a progressive deployment approach that demonstrates to have a great potential of reducing trafc congestions at low CACC penetration levels.Using a previously developed microscopic trafc simulation model of a freeway with an on-ramp—created to induce perturbations and trigger stop-and-go trafc,the CACC system s efect on the trafc performance is studied.The results show signifcance and indicate the potential of CACC systems to improve trafc characteristics which can be used to reduce trafc congestion.The study shows that the impact of CACC is positive and not only limited to a high market penetration.By giving CACC vehicles priority access to high-occupancy vehicle(HOV)lanes,the highway capacity could be signifcantly improved with a CACC penetration as low as 20%.
