In order to improve control performance and eliminate steady, a coupling compensation for 6-DOF parallel robot is presented. Taking dynamic load Tank Simulator as the research object, this paper analyzes the coupling of 6-DOC parallel robot considering the degree of freedom of the 6-DOF parallel manipulator. The coupling angle and coupling velocity are derived based on inverse kinematics model....

We construct R-invariant unification models where a pair of mass-less Higgs doublets is naturally obtained. The masslessness of the Higgs doublets is guaranteed by the unbroken R symmetry. Mass generation for the Higgs doublets is considered from various viewpoints.

We report on work studying the properties of the sphaleron in models of the electroweak interactions with two Higgs doublets in as model-independent a way as possible: by exploring the physical parameter space described by the masses and mixing angles of the Higgs particles. If one of the Higgs particles is heavy, there can be several sphaleron solutions, distinguished by their properties under...

Interaction-driven spontaneous symmetry breaking lies at the heart of many quantum phases matter. In moir\'e systems, broken spin/valley 'flavour' in flat bands underlies parent state out which ultimately correlated and topological ground states emerge. However, microscopic mechanism such flavour its connection to low-temperature many-body remain be understood. Here, we investigate symmetry-bro...

This paper presents construction of a composite right/left-handed (CRLH) transmission line (TL) based bandpass filter using microstrip parallel coupled lines and hairpin lines. For getting high coupling in comparison to conventional edge coupled microstrip line, the floating slot on the ground plane is used. Two configuration named as SOS (short-open-short) the OSO (open-short-open) model are s...

Gauge-coupling unification is just as successful in the standard model with six Higgs doublets as it is in the minimal supersymmetric standard model. However, the gauge couplings unify at 10 GeV, which yields rapid proton decay in the SU(5) model. I propose that the grand-unified gauge group is instead SU(3)c × SU(3)L × SU(3)R, in which baryon number is conserved by the gauge interactions. Natu...

of the genetic code. Why are there strong and weak letter doublets? The first gene, the first protein. Early (ancient) biosynthesis of protein. The idea of the evolution of the genetic code from the CG to the CGUA alphabet has been developed further. The assumption of the originally triplet structure of the genetic code has been substantiated. The hypothesis of the emergence of stop codons at t...

The recent LEP data for gauge coupling constants constrain many grand unified models. In this paper, we study several possibilities for unification of gauge coupling constants. Without an intermediate scale, the minimal supersymmetric standard model with two Higgs doublets is the only possibility. For one intermediate scale, we present a few unification schemes without supersymmetry. One of the...

The compilation of FORTRAN programs for SPMD execution on parallel architectures often requires the application of program restructuring transformations such as loop interchange, loop distribution, loop fusion, loop skewing and statement reordering. Determining the optimal transformation sequence that minimises execution time for a given program is an NP-complete problem. The hypothesis of the ...
