Reliable measurements of ball mill load parameters and reorganization of the operating statuses are the key factors for saving energy and optimization control. Empirical mode decomposition (EMD) and partial least squares (PLS) are used to analyze shell vibration signal and monitor mill load parameters of ball mill. The shell vibration signal is decomposed into several intrinsic mode functions (...

A customer who places a tentative order at a steel mill customarily receives a due-date quotation, namely the date by which the mill says that it will ship the order. The steel mill wants the due date to be early enough so that the customer won’t balk (withdraw the order), but late enough so that the probability of tardiness is low. This note obtains expressions for the tardiness probability at...

Turn to turn fault is one of the major internal failures in the power transformers that if it is not quickly detected, can be extended and led to a complete transformer breakdown. So, the diagnosis and location of the turn to turn fault of the power transformer, as one of the most important equipment in the power system, is the main objective of this paper. For this purpose, a detailed model of...

Three species of fish, caught at various distances from a kraft pulp ai:d paper mill effluent discharge in Nipigon Bay, were analyzed for organic contaminants. Fishes from all sites contained residues of polychlorinated biphenyls and DDE. Most samples were also contaminated with hexachlorobenzene and several samples contained phthalic acid esters. From sampling sites close to the mill discharge...

The present study aims to develop a dynamical model of cement milling process as well as an autoregressive model of the errors of the previous one. Modeling is based exclusively on long term industrial data sets of five cement mills. Not only the dynamics of each mill is estimated but also separate dynamical parameters are computed for each cement type processed in the same mill. Detailed infor...

The quality of steel strip produced in a wide strip rolling mill depends heavily on the careful selection of initial ground work roll profiles for each of the mill stands in the finishing train. In the past, these profiles were determined by human experts, based on their knowledge and experience. In this research, a Self-Organising Migration Algorithm (SOMA), a heuristic optimisation algorithm,...

Ahmedabad, India’s sixth largest city, saw widespread religious violence in 2002. Using detailed neighborhood level data we show that riot incidence is positively predicted by a neighborhood’s proximity to the, by now largely derelict, textile mills. Mill neighborhoods also exhibit higher levels of religious integration, a fact we trace to the historical religious heterogeneity in the mill work...

as Ph.D., D.C.L., LL.D.! However, his status as a Commissioner of Deeds for various States of the Union was ended by the commissions being revoked, and he was compelled to return his " papers," which had to do with an institution that had taken over the business of the Western University of Illinois, which in its turn was, through one Henry Clough, connected with an equally fraudulent degree-mi...

Given a simple generalized polygonA of line segments and arcs that is free to move and rotate and an oriented monotone chainB composed of smooth parametric curved edges, the positions and orientations forA to gouge-freely contactB (i.e., the contact configurations) is a C0 continuous surface in a three dimensional space R3. Past results either limitB to be polygonal or depend on the very compli...
