Blending Problem

This paper introduces a new technology using a new mathematics model to solve the blending problem of two or more kinds of minerals, which grades are very different even in orders of magnitude, and creates a blending system which can produce an optimal program of blending automatically using a feedback process based on Surpac, a mining software, and achieves a real time truck dispatching system finally. All of above can improve quality and quantity of the minerals blending stably, that has been proved in practice. According 2001s record, this system had the Cu grade amplitude down from 10.54% to 3.72% and the Mo grade amplitude from 6.49% to 3.11%.

Research Challenge

With the rapid expansion of the campus scale and the increasing of the geographically dispersed campus, how to adopt new theory, new method and new technology to realize the equipment optimized assignment and the information management is a new research challenge. It is the key to safeguard the national fund to use reasonably, and to speed up the development of education healthily. Through analyzing the domestic and foreign related research works, the paper proposed that it can take use of the spatial data expression and analysis with Geographic Information System (GIS) to realize the large-scale and inter-campuses equipment optimized assignment and information management. It discussed the mathematics model and the system architecture. Moreover, the paper described the key implementation technology in great detail such as spatial data mapping with MapInfo professional 9 and the development of WebGIS functions with MapXtreme. The results show that the solution is feasible and effective.

Abstract—An online automatic disaster monitoring system can reduce or prevent geological mine disasters to protect life and property. Global Navigation Satellite System receivers and the GeoRobot are two kinds of in-situ geosensors widely used for monitoring ground movements near mines. A combined monitoring solution is presented that integrates the advantages of both. In addition, a geosensor network system to be used for geological mine disaster monitoring is described. A complete online automatic mine disaster monitoring system including data transmission, data management, and complex data analysis is outlined. This paper proposes a novel overall architecture for mine disaster monitoring. This architecture can seamlessly integrate sensors for long-term, remote, and near real-time monitoring. In the architecture, three layers are used to collect, manage and process observation data. To demonstrate the applicability of the method, a system encompassing this architecture has been deployed to monitor the safety and stability of a slope at an open-pit mine in Inner Mongolia.

Microfluidic technology has tremendously facilitated the development of in vitro cell cultures and studies. Conventionally, microfluidic devices are fabricated with extensive facilities by well-trained researchers, which hinders the widespread adoption of the technology for broader applications. Enlightened by the fact that low-cost microbore tubing is a natural microfluidic channel, we developed a series of adaptors in a toolkit that can twine, connect, organize, and configure the tubing to produce functional microfluidic units. Three subsets of the toolkit were thoroughly developed: the tubing and scoring tools, the flow adaptors, and the 3D cell culture suite. To demonstrate the usefulness and versatility of the toolkit, we assembled a microfluidic device and successfully applied it for 3D macrophage cultures, flow-based stimulation, and automated near real-time quantitation with new knowledge generated. Overall, we present a new technology that allows simple, fast, and robust assembly of customizable and scalable microfluidic devices with minimal facilities, which is broadly applicable to research that needs or could be enhanced by microfluidics.

Video And Audio

In the previous chapters three real time communications technologies (RTCs) have been discussed. Videoconferences have been used for real time communications in distance learning for many years. In recent years many institutions have used videoconferences in addition to the text-based communications tools in learning management systems: discussion forums and chat. Video chat is a new technology. It is computer based and inexpensive after the purchase of the computer as software is often free and the basic audio and video equipment is inexpensive. Video chat facilitates two-way video and audio communications and thus it is likely to displace videoconference from its place in the market. The Access Grid is also gaining use in education as a teaching tool due to the richness of the experience of multiple video streams, and additional tools that allow true collaboration. How these technologies are used in educational settings has a direct impact on the effectiveness and efficiency of the educational experience and theoretical guides to their use have been discussed earlier in this book. One of the early theoretical approaches was that put forward by Michael Moore.

It is no wonder that the average citizen is concerned about the difficulty of guarding one’s privacy. Now, your own cell phone can reveal your ever-changing whereabouts by means of “location technology” (Lagesse, 2003). Chips that receive coordinates from global positioning satellites now make it possible to locate persons, cars, merchandise, in short, whatever we value. Like most new technology, it is easy to see advantages as well as drawbacks. Some positives of location technology are that ambulances, police and fire services can reach victims more quickly; driving suggestions can be delivered in real time to motorists (thus helping to avoid traffic tie-ups and prevent getting lost); advertisers can inform potential customers of the existence of a nearby hotel, store or restaurant; stores utilizing RFID (see the KEY TERMS section for explanations of possibly unfamiliar terms) can trace merchandise movement to reduce waste, replenish inventory, and stem shoplifting. Some negatives are that nefarious agents can also use location technology to track their prey; location-tracking history can be subpoenaed by one’s legal adversaries; and it is inevitable that corporations and government will have an interest in conducting such monitoring (Griffin & Whitehead, 2001, 2002).

PurposeThe purpose of the paper is to discuss the scope for improving the delivery of FM services through the use of wireless web‐based communications infrastructure, delivered via an application service provider (ASP) business model. This paper discusses the findings from case studies of three organisations and their approach to the management of facilities.Design/methodology/approachAn investigation was undertaken to ascertain the current state of play in terms of managing and tracking processes within the facilities management department of three different organisations. These case studies were chosen from distinct sectors, namely health care, higher education, and banking. Emphasis is placed on analysing how the organisations currently operate with their existing FM systems and the degree of influence technology has on existing processes. This was considered mainly in terms of computer‐aided facilities management (CAFM) and computer‐integrated facilities management (CIFM).FindingsThe study found that a new wireless web‐based service for FM systems would be considered useful. Although notoriously slow adopters of new technology, there was an acceptance by the facilities managers interviewed that a wireless web‐based approach would improve current practice, especially with respect to real‐time job reporting and tracking and in the determination of FM operative working time utilisation.Practical implicationsFurther work by the author is focusing on the development of a suitable demonstrator to illustrate the key concepts of a wireless web‐based FM service which will then be tested and evaluated. For further information, visit the research project web site at www.wirelessfm.org Originality/value – The paper hopefully stimulates discussion in the area of emerging wireless technologies that have the potential to streamline and improve current practices for the management of facilities, in particular that of real‐time job reporting and tracking.
