Low grade diasporic bauxite in the Jajarm mine with an A/S (Al2O3/SiO2) ratio of 2.3 is not usable in the Bayer process at Jajarm Alumina Complex. Due to the severe interlocking effect between the diaspore and aluminosilicate minerals (Chamosite and Kaolinite) and iron-containing minerals in a microcrystal matrix, the thermo-chemical treatment, which is independent from micro-mineralogy, was ch...

We describe an automatic image enhancement technique based on features extraction methods. The approach takes into account images in Bayer data format, captured using a CCD/CMOS sensor and/or 24-bit color images; after identifying the visually significant features, the algorithm adjusts the exposure level using a “camera response”-like function; then a final HUE reconstruction is achieved. This...

Simulation is a relatively new tool for business process analysis in the Biotech industry. This paper discusses an application of discrete event simulation in analyzing the capacity needs of a shared resource in the manufacturing facility at Bayer Corporation’s Berkeley site. The SIGMA simulation model was used to analyze the workload patterns, run different workload scenarios, taking into cons...

While most imaging devices use the Bayer pattern, virtually all vision methods assume the availability of information for a complete color space. This creates the need for demosaicing step, for which even the fastest naïve interpolation is in some applications a computational burden. In this paper, a complete real-time vision infrastructure is built directly upon the Bayer pattern without inter...

Our recent study showed that the Bayer-dithering technique could substantially improve 3D measurement quality for the binary defocusing method. Yet, the dithering technique was developed to optimize the appearance or intensity representation, rather than the phase, of an image. This paper presents a framework to optimize the Bayer-dithering technique in phase domain by iteratively mutating the ...

This paper addresses the problem of interpolating missing color components at the output of a Bayer color filter array (CFA), a process known as demosaicking. A luma-chroma demultiplexing algorithm is presented in detail, using a least-squares design methodology for the required bandpass filters. A systematic study of objective demosaicking performance and system complexity is carried out, and ...

Most color imaging systems today are based on a monochrome detector with a color filter array (CFA). Typically the Bayer CFA is used. An imaging system’s spatial frequency response (SFR) is one of its most meaningful characteristics. It is directly related to the system’s capability to resolve objects. This work presents a model for calculating the SFR of a Bayer color capture system. Our two d...

Two well known derivatization methods, butylation and methylation, are compared by gas chromatography (GC)-mass spectrometry (MS) to identify organic acids in Bayer liquors. These two derivatization methods should be combined together for the determination of the carboxylic acids. Twenty-four organic acids are identified by GC-MS and 13 organic acids are firstly found in Bayer liquors. The rete...
