Evaluating the effectiveness and performance of neuromorphic hardware is difficult. It is even more difficult when the task of interest is a closed-loop task; that is, a task where the output from the neuromorphic hardware affects some environment, which then in turn affects the hardware's future input. However, closed-loop situations are one of the primary potential uses of neuromorphic hardwa...

1 By Keith Dunne and John F. Russo C losed-loop water recycling is only one of several alternatives available when converting. to aaueous or semiaqueous cleaning. Most CFC users have been accustomed to operating a mature and well-defined process. Conversion to other cleaning technologies has forced users to develop entirely new skills and to develop a good working knowledge of the chemistry of ...

Background The purpose of this study was to evaluate electrode temperatures obtained using a radiofrequency ablation system that incorporates closed loop feedback control to achieve preset target electrode temperatures and to determine if closed loop temperature control results in a lower incidence of developing a coagulum. Methods and Results Two hundred seventy patients underwent catheter abl...

The technique described in this paper uses singular perturbation and balanced structure to reduce the order of a large-scale plant model over a finite frequency range of operations pre-specified by the designer. This method reduces error rate in model reduction of real equipment that has to operate within a finite frequency range. The outcome of reducing the model within a specified frequency r...

green supply chain management is an environmental approach in supply chain management that aims to decrease ecological risks in products’ life cycle. closed-loop supply chain by collecting and recycling the harmful production in nature attempts to achieve this goal. in this paper, due to different strategies in collecting products, several pricing models in two-echelon closed supply chain are p...

This paper is concerned with a novel kind of deployable structures that form closed loops that fold into a bundle of bars using simple hinges. These structures, first envisaged by Dr J.M. Hedgepeth, have potential applications for ultra-lightweight solar arrays, solar sails, and radar structures. A systematic study of the kinematics of closed-loop structures is carried out, and a scheme for sim...

Output noise is strongly related to input in closed-loop control system, which makes model identification of closed-loop difficult, even unidentified in practice. The forward channel model is chosen to isolate disturbance from the output noise to input, and identified by optimization the dynamic characteristics of the process based on closed-loop operation data. The characteristics parameters o...

Solar collector water heating system use solar thermal energy to provide hot for domestic and industrial use. These systems are operated either as open-loop or closed-loop flow circuit. The former loop not recommended the cold climates having freezing problem. Although previous studies on collectors have used operation with working fluid. However, it must high boiling low points colder regions ...

Historically, sensor noise has been a key factor in the analysis of system performance for formation flying spacecraft. Since most interesting formation missions require coordination between multiple spacecraft, knowledge of the relative states must be as accurate as possible. This knowledge is typically used to design a trajectory to meet specific criteria, such as minimizing fuel use or maint...

The Toxics Use Reduction Institute is a multi-disciplinary research, education, and policy center established by the Massachusetts Toxics Use Reduction Act of 1989. The Institute sponsors and conducts research, organizes education and training programs, and provides technical support to promote the reduction in the use of toxic chemicals or the generation of toxic chemical byproducts in industr...
