The airborne hyper-spectral survey system CASI/SASI, which has an integrated for gathering both image spectral data, is at the cutting edge developments in remote-sensing field. It can be used to directly identify surface objects based on diagnostic characteristics. In this paper, CASI/SASI were Huaniushan gold-silver-lead-zinc ore district–Gansu produce a lithologic map, altered minerals, and ...

Crushers play an important role in the comminution of minerals and the control of its operation can lead to an increase of the plant throughput and efficiency. This work presents a simple but effective method for controlling a crusher circuit by acting over the feeder and the speed of the conveyor belt carrying out the mineral up to the crusher. Guidelines for tuning the strategy, as well as pr...

Localization for industrial vehicles is a key issue in the development and use of autonomous systems on industrial worksites. The WiFi technology being widely used in such environments can be used as a base for an easy to set up system requiring little hardware. In this paper we propose a system estimating the location of industrial vehicles, based only on WiFi signals, that can operate both in...

Historians attribute the Egyptians in the Nile Delta with preparing the first type of paper, from a marsh grass called Cyperus papyrus. They cut the plant’s stem into thin strips, softened them in the river, and then pounded them into thin sheets that were then left to dry in the sun. The resulting sheets were ideal for writing on, and Egyptians, Greeks, and Romans used them for record keeping,...

Introduction: Determining the mineralogy of Mars constitutes an essential part of understanding of the present and past condition of the surface. After two years of operation, the OMEGA imaging spectrometer on-board Mars Express has achieved near-global coverage with spatial resolution varying between 300 m and 4.8 km depending on the pericentre altitude of the spacecraft's highly elliptical or...

The Hyperspectral Infrared Imager (HyspIRI) is a proposed NASA satellite remote sensing system combining a visible to shortwave infrared (VSWIR) imaging spectrometer with over 200 spectral bands between 0.38 and 2.5 μm and an 8-band thermal infrared (TIR) multispectral imager, both at 60 m spatial resolution. Short Wave Infrared (SWIR) (2.0–2.5 μm) simulation results are described here using Ai...

The process of building organic-inorganic compound structures through biomineralization is extremely impressive and potentially very useful. During biomineral formation, organisms restructure simple, naturally occurring minerals in conjunction with their own organically produced minerals to create new structures, the functions of which often include protection or storage, among others. While th...

1.0 Introduction Imaging Spectrometry data or Hyperspectral Imagery (HSI) acquired using airborne systems have been used in the geologic community since the early 1980’s and represent a mature technology (Goetz et al., 1985; Kruse et al., 1999). The solar spectral range, 0.4 to 2.5 μm, provides abundant information about many important Earth-surface minerals (Clark et al., 1990). In particular,...
