Wheeled mobile robot trace tracking method based on quantum behavior particle cluster algorithm

The invention discloses a method for tracing the track of a wheeled mobile robot based on a quantum-behaved particle swarm algorithm. The method sets a coordinate system within a motion range first, establishes a kinematic model of the wheeled robot, utilizes an inversion design method to decompose the kinematic model, obtains an error propagation equation of a reference pose and an actual pose through the track generated by path planning, takes the equation as a target function, utilizes the quantum-behaved particle swarm optimization algorithm to obtain parameters of a controller with quick speed and strong global solving capacity, designs the controller through the group of parameters, and further guarantees that the robot can be stably and quickly converged on the target track, namely the target function value is close to or less than an allowable value within a limited time period. The method solves the problems of high nonlinearity and non-integrity of track tracing of the wheeled mobile robot, and can quickly realize track tacing of the wheeled mobile robot and improve the tracing control effect of the mobile robot.

Next generation terrestrial broadcasting platform aligned internet and towards emerging 5g network architectures

A Next Generation Broadcast Platform (NGBP) is disclosed that utilizes 5G software-defined networking (SDN) and network function virtualization (NFV) technologies. The NGBP is designed to enable a new paradigm for broadcasters, wherein the model of fixed wireless spectrum access granted only to the licensees of the spectrum is replaced by a flexible model in which licensed spectrum is pooled together and allocated dynamically to broadcast licensees as well as outside tenants. The NGBP is implemented using SDN / NFV technology, and includes a broadcast market exchange (BMX) entity that allocates the spectrum between tenants based on service level agreements (SLAs) with those users. The NGBP also includes an internet protocol (IP) core and a broadcast centralized radio access network (BC-RAN) which apply the major network functions to broadcaster content in accordance with the determinations of the BMX. The SDN / NFV implementation offers several distinct advantages over NGBP implemented with dedicated network hardware.

Process for making polybutylene terephthalate (PBT) from polyethylene terephthalate (PET)

The invention relates to a process for making modified polybutylene terepththalate random copolymers from a polyethylene terephthalate component. In one embodiment, the invention relates to a two step process in which a 1,4-butane diol component reacts with a polyethylene terephthalate component under conditions that depolymerize the polyethylene terephthalate component into a molten mixture and the molten mixture is placed under subatmospheric conditions that produce the modified polybutylene terepththalate random copolymers. In another embodiment, the invention relates to a three step process in which a diol component selected from the group consisting of ethylene glycol, propylene glycol, and combinations thereof reacts with a polyethylene terephthalate component under conditions sufficient to depolymerize the polyethylene terephthalate component into a first molten mixture; and where the first molten mixture is combined with 1,4-butane diol under conditions that create a second molten mixture that is subsequently placed under subatmospheric conditions that produce the modified polybutylene terepththalate random copolymers. The invention also relates to compositions made from processes of the invention.
