A bstract The naive double-copy of (multi) loop amplitudes involving massive matter coupled to gauge theories will generically produce in a gravitational theory that contains additional contributions from propagating antisymmetric tensor and dilaton states even at tree-level. We present graph-based approach combines the method maximal cuts with construction offer systematic framework isolate pu...

In parallel transmission system, the wide diameter has become an important factor to measure transmission efficiency instead of the diameter. The minimum distance diagram of a directed doubleloop network yields an L-shaped tile, an L-shaped tile can be described by four geometric parameters: a, b, p and q, let m1⁄4a–p, n1⁄4b q, the L-shaped tiles can be classified into 4 types according to the ...

Applications are given of a preconditioned adaptive algorithm for broadband multichannel active noise control. Based on state-space descriptions of the relevant transfer functions, the algorithm uses the inverse of the minimum-phase part of the secondary path in order to improve the speed of convergence. A further improvement of the convergence rate is obtained by using double control filters f...

Students in work based settings gain access to a vast amount of knowledge. This workshop contribution introduces micro articles as a tool to make practical knowledge persistent. Micro articles are used to establish double loop learning in the sense that the learners not only consume but also provide learning objects. The aspired effects are a deeper reflection for the original learner as well a...

A crucial role in representation theory of loop groups of reductive Lie groups and their Lie algebras is played by their non-trivial second cohomology classes which give rise to their central extensions (the affine Kac–Moody groups and Lie algebras). Loop groups embed into the group GL∞ of continuous automorphisms of C((t)), and these classes come from a second cohomology class of GL∞. In a sim...

this paper presents a new control structure to reduce torque ripple in switched reluctance motor. although srm possesses many advantages in motor structure, it suers from large torque ripple that causes some problems such as vibration and acoustic noise. in this paper another control loop is added and torque ripple is de ned as an objective function. by using fuzzy sliding mode strategy, the dc...

Probabilistic data structures are so popular in membership queries, network applications, and so on. Bloom Filter and Cuckoo Filter are two popular space efficient models that incorporate in set membership checking part of many important protocols. They are compact representation of data that use hash functions to randomize a set of items. Being able to store more elements while keeping a reaso...

In this paper a novel direct adaptive fuzzy system is proposed to control flexible-joints robot including actuator dynamics. The design includes two interior loops: the inner loop controls the motor position using proposed approach while the outer loop controls the joint angle of the robot using a PID control law. One novelty of this paper is the use of a PSO algorithm for optimizing the contro...
