This paper presents an approximate multi-parametric nonlinear programming approach to explicit solution of constrained nonlinear model predictive control (MPC) problems in the presence of model uncertainty. The case of time-invariant parameter uncertainty is considered. The explicit MPC controller is based on an orthogonal search tree structure of the state space partition and is designed by so...

after protein phosphorylation returns to basal levels), the potentiatory effect on 5-HT secretion seems to be selectively 'desensitized' or 'switched-off' with incubation periods > 2 min or > 20 min in stirred and unstirred platelets, respectively, even in the presence of sustained 45 kDa protein phosphorylation. As the time of onset of this process and the inhibition of agonist-induced 5-HT se...

Bacterial infection shortly after mating interferes with establishment of pregnancy. Injection of peptidoglycan-polysaccharide (PG-PS), a component of gram-positive bacteria, into sheep on day 5 after mating reduces pregnancy rate. Experiments were designed to evaluate the acute-phase response (APR) in ewes to injection of PG-PS on day 5 after mating (day 0). Catheters were inserted into the ju...

Introduction: Textile industries produce large volume of colored dye effluents which are toxic and removal of dyes from wastewater is a significant environmental issue. Advanced oxidation process (AOPs) is alternative method for the complete degradation many organic pollutants. ZnO and TiO2 are important photocatalysts with high catalytic activity that have attracted much research attention. ...

To reduce the shortcomings of existing filtering assistance, talc was modified by a two-step method. In first step, talcum powder heated microwave in acid solution. second stirred with Hexadecyl Trimethyl Ammonium Bromide (HTAB) solution for optimum time under an temperature. The temperature, and amount HTAB were investigated batch membrane filtration experiments kaolin suspension. effects new ...

Friction Stir Processing (FSP) is a method for solid-state processing, in which rotating tool moved onto the material surface to modify microstructure and thus obtain improved properties of surface. We study effects FSP on aluminium alloy A6061-T651 using made at Institute Metal Science, Equipment, Technologies with Centre Hydro- Aerodynamics (IMSETCHA) Bulgarian Academy Sciences. The has threa...

Introduction - Thermoplastic polymers have many potential uses in medicine and dentistry as an alternative to the commonly used titanium. Since 1980s, polyaryletherketones (PAEKs) been increasingly employed biomaterials for trauma, orthopedic, spinal implants. Due several advantages of these materials, metal-free restorations are performing important role current medical therapies. PEEK is biol...

room temperature and then maintained at 80°C for 3 h to form micro-cubic PB particles. The solid product was collected by centrifugation and washed six times with Milli-Q water. The final PB product was then dried in a vacuum oven. The GO was synthesised by a modified Hummer's method. [1] To prepare GOPCs, the GO and PB were stirred together in an aqueous solution to form slurries with differen...
