Quentin Skinner is an intellectual historian known for his pioneering work on early-modern European political thought. He was educated at Bedford School and Gonville and Caius College, Cambridge. Author of such works as The Foundations of Modern Political Thought (1978) and Visions of Politics (2002) he served as the Regius Professor of History at the University of Cambridge, and currently as t...

This paper is concerned with the application of Kalman filter based methods for Fault Detection and Identification (FDI). The original Kalman based method, formulated for bias faults only, is extended for three more fault types, namely the actuator or sensor being stuck, sticky or drifting. To benchmark the proposed method, a nonlinear buffer tank system is simulated as well as its linearized v...

High water usage is necessary while ore passes through the many stages of a mineral processing plant. However, dewatering system filters final pulp product to remove water, which reutilized in previous processes. This step fundamental reducing fresh new consumption. Usually, several tanks, pumps, and form system—any failure or shutdowns from those components disbalance flow. The waste tons prod...

An electroplating, or chemical treatment, line is composed of (see fig 1) : tanks containing each a chemical reagent, an input and an output buffer, hoists transporting the products from tank to tank. Therefore, a treatment results from the successive immersion of a product in several tanks. Tanks and hoists can only process one job at a time. Specific chemical constraints exist : • once a prod...

Buffer tanks are widely used within the process industry to prevent flow variations from being directly propagated throughout a plant. The capacity of the tank is used to smoothly transfer inlet flow upsets to the outlet. Ideally, the tank thus works as a low pass filter where the available tank capacity limits the achievable flow smoothing. For infrequently occurring upsets, where the system h...

The judicious use of buffering capacity is important in the development of future continuous pharmaceutical manufacturing processes. The potential benefits are investigated of using optimal-averaging level control for tanks that have buffering capacity for a section of a continuous pharmaceutical pilot plant involving two crystallizers, a combined filtration and washing stage and a buffer tank....

B iopharmaceutical processes are operated in aqueous systems using large quantities of WFI or Purified Water (PW). In the upstream process (USP), WFI is required for media preparation and feed solutions. In the downstream process (DSP), large quantities of PW or WFI are required for buffers, with buffer preparation, buffer storage, and distribution systems representing a significant portion of ...

Štúdium viazania stopových prvkov v sedimente vodnej nádrže Ružín Pre účely posúdenia možnosti využitia fyzikálnych a fyzikálno-chemických metód separácie, vybraná vzorka sedimentu z Ružína bola podrobené 5-stupňovej procedúre sekvenčnej extrakcie (SE) podľa Tessiera (Tessier et al., 1979) a Horowitza (Horowitz, 1991). Vo výluhoch bolo stanovované zastúpenie konštitučných (Fe, Mn, Ca a Mg) ako ...
