Metals used in everyday life are produced from ores occurring in the Earth’s crust. Geological processes are known to concentrate minerals to form ores of economic value. Mineral processing engineers concentrate these ores by mechanical and physico-chemical methods while the extractive metallurgist extracts the metals by chemical means.

The last two decades have shown a major shift from stand-alone software systems to networked ones. As with all information system domains, Geographic Information Systems (GISs) have been influenced to a large extent by recent internet developments, resulting in an increasing availability of client/server applications using distributed geo-(web-)services, such as interactive maps, route planners...

The purpose of this study was to determine the accuracy of GPS use for a geosynchronous (GEO) satellite. Current missions at GEO altitude mainly use traditional ranging for orbit determination. With changing mission requirements and the increase in the number of GEO missions, utilizing GPS signals is becoming an increasingly attractive alternative for position and timing determination. A previo...

Slope failure is a common phenomenon all over the world on both man-made and natural slopes. Prolonged rainfall one of climatic factors which largely responsible for slope failure. During heavy prolonged rainfall, part rainwater infiltrates through soil seeps into slope. The infiltrated water lowers matric suction increases porewater pressure. Eventually, generated pressure decreases strength r...

The current international society has entered an era of large-scale power transfer. Government interests have gradually transferred from national strength to national influence. As such, how to quantitatively present the fuzzy geopolitical influence (i.e., geo-influence) has attracted greater attention from scholars. The proposed concept of geo-influence conforms to this trend of power structur...

Geo-replication is the process of maintaining copies of data at geographically dispersed datacenters for better availability and fault-tolerance. The distinguishing characteristic of geo-replication is the large wide-area latency between datacenters that varies widely depending on the location of the datacenters. Thus, choosing which datacenters to deploy a cloud application has a direct impact...

1 Summary Network scalability is one of the critical challenges and requirements in routing protocols for ad hoc networks. This paper presents a novel scalable routing protocol called Geo-LANMAR. The proposed protocol inherits the group motion support of Landmark Routing (LANMAR) and applies the geo-routing concept to deliver packets efficiently. In this framework, the integration between geo-c...

The Software Development Studio is the centerpiece of Carnegie Mellon's Master of Software Engineering Curriculum. It represents 40 per cent of the course units students spend in the program. The Studio has continuously evolved since its prototype in the spring and summer of 1990. The lessons learned about organization, projects, and other issues are the subject of this paper. The use of a well...

This paper aimed to study the soil–water characteristics and stability evolution law of rainfall-induced landslide. Taking two landslide events in Siwan village as an example, formation conditions disaster were analyzed. Additionally, deformation destruction mechanisms landslides discussed in-depth. The hydraulic conductivity analyzed based on TRIM experiment results. Geo-Studio numerical softw...
