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...

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...

In this paper, a systematic overview of PLL-based closed-loop control methods for interleaved DCM/CCM boundary boost PFC converters is presented. It is shown that the PLL-based closed-loop methods always provide stable operation, unlike the open-loop control methods, where the only method which results in stable operation is the slave synchronization to the turn-on instant of the master with cu...

We review the polynomial matrix compensator equation XlDr + YlNr = Dk (COMP), e.g. (Callier and Desoer, 1982, Kučera, 1979; 1991), where (a) the right-coprime polynomial matrix pair (Nr,Dr) is given by the strictly proper rational plant right matrix-fraction P = NrD−1 r , (b) Dk is a given nonsingular stable closed-loop characteristic polynomial matrix, and (c) (Xl, Yl) is a polynomial matrix s...

time-delays are important components of many dynamical systems that describe coupling or interconnection between dynamics, propagation or transport phenomena, and heredity and competition in population dynamics. the stabilization with time delay in observation or control represents difficult mathematical challenges in the control of distributed parameter systems. it is well-known that the stabi...

We derive the Schwinger-Dyson/loop equations for the USp(2k) matrix model which close among the closed and open Wilson loop variables. These loop equations exhibit a complete set of the joining and splitting interactions required for the nonorientable TypeI superstrings. The open loops realize the SO(2nf ) Chan-Paton factor and their linearized loop equations derive the mixed Dirichlet/Neumann ...

We calculate the 10 × 10 two–loop anomalous dimension matrix to order O(ααs) in the dimensional regularization scheme with anticommuting γ5 (NDR) which is necessary for the extension of the ∆S = 1 weak Hamiltonian involving electroweak penguins beyond the leading logarithmic approximation. We demonstrate, how a direct calculation of penguin diagrams involving γ5 in closed fermion loops can be a...
