This paper reviews the experimental synthesis and engineering developments that focused on various green approaches and large-scale process production routes for quantum dots. Fundamental process engineering principles were illustrated. In relation to the small-scale hot injection method, our discussions focus on the non-injection route that could be scaled up with engineering stir-tank reactor...

multiphase impeller stirred tank reactors enhance mixing of reacting species used in a variety of chemical industries. these reactors have been studied based on computational fluid dynamics (cfd) that can be used in the analysis, design and scale up of these reactors. most of the researches done in this area are limited to single phase reactors, and a few remaining two phase flow investigations...

Knowledge and control of mixing in batch processes can prevent yield losses during scale-up. Therefore, this study, a new heat-mixing model based ono the measurement heat distribution after an applied pulse, is proposed. The was developed to predict mesomixing support scale-up, scale-down, design optimisation reactors. proposed considers influences rotational speed, stirrer type, solvent, stirr...

1. Supported by FCT grant PRAXIS XXI/BD/13875/97 Abstract This paper presents an original approach to the problem of function hiding based on Error Correcting Codes and evaluates the security of this approach. The novelty of the technique consists in using Error Correcting Codes to hide functions instead of encrypting data vectors. This protocol mainly deals with the issue of secure evaluation ...

The effect of the nucleon recoil for antikaon-deuteron scattering is investigated in the framework of effective field theory. In particular, we concentrate on the calculation of the nucleon recoil effect for the double-scattering process. It is shown that the leading correction to the static term that emerges at order ξ with ξ = MK/mN vanishes due to a complete cancellation of individually larg...

A fungal consortium including Aspergillus niger, Mucor hiemalis and Galactomyces geotrichum was tested for the treatment of dairy wastewater. The bio-augmentation method was tested at lab-scale (4 L), at pilot scale (110 L) and at an industrial scale in Wastewater Treatment Plants (WWTP). The positive impact of fungal addition was confirmed when fungi was beforehand accelerated by pre-culture o...

in this study, the effects of oxygen supplementation in different stocking densities of rainbow trout (oncorhynchus mykiss) on the specific growth rates (sgr), feed conversion ratios (fcr) and survival rates were investigated in a commercial-scale culture system. high density cultures were maintained in a total of nine (12 m3) flow-through systems supplemented with o2. initial stocking rates fo...

This paper presents an enhanced version of a portable outof-the-box platform for semi-immersive interactive applications. The enhanced version combines stereoscopic visualization, marker-less user tracking, and multi-touch with self-reflection of users and tangible object interaction. A virtual fish tank simulation demonstrates how real and virtual worlds are seamlessly blended by providing a m...

Supervisory control usually involves timely switching among different courses of action over multiple time scales. In this work, intelligent process supervision is addressed in the context of semi-Markov decision processes and reinforcement learning. Temporally extended actions that represent a way of behaving together with a termination condition are used to achieve a set of operational goals/...

This paper deals with Fault Detection Identification and Isolation (FDII) in actuators and system (component) applied to a Semi Continuous Stirred Tank Reactor(SCSTR). The proposed FDII is based on high gain observers, for detecting faults of actuators and system component. This algorithm has the advantage of detecting multiple faults simultaneously. The observer is constructed from a sub-model...
