This paper presents the fomulation of the inverse kinematics and dvnamics of the1 3-RRS parallel platform with three degrees of freedom. For inverse kinematics, The position analysis is f irs f ly performed. Then the differential motion constraint vquations of the movable platform are established, based on which the velocity and acceleration formulae of leg actuators are derived. In inverse dyn...

Abstract The low-temperature electrolysis of CO 2 in membrane-based flow reactors is a promising technology for converting captured into valuable chemicals and fuels. In recent years, substantial improvements reactor design have significantly improved the economic viability this technology; thus, field has experienced rapid increase research interest. Among factors related to design, ion exchan...

The respiratory resistive properties of the normal human respiratory system are volume-dependent. The overall flow resistance (Rmax,rs) can be partitioned into airway resistance (Raw) and the additional resistance (delta Rrs) which may result from the viscoelastic properties of the respiratory system, from inequality of time constants (pendelluft), or from both. Because positive end-expiratory ...

Objective This systematic review aimed to define the relationship between diabetes mellitus (DM) and the risk of aneurysmal subarachnoid haemorrhage (aSAH). Methods Studies associated with DM and aSAH published until March 2016 were retrieved from Pubmed, Embase, Web of Science, and Cochrane Library databases. A random-effects model was used to calculate the relative risks (RRs) with 95% confid...

This paper proposes a new heuristic search algorithm, Recursive Random Search(RRS), for blackbox optimization problems. Specifically, this algorithm is designed for the dynamical parameter optimization of network protocols which emphasizes on obtaining good solutions within a limited time frame rather than full optimization. The RRS algorithm is based on the initial high-efficiency property of ...

The nanogold reaction between HAuCl4 and citrate is very slow, and the catalyst graphene oxide nanoribbon (GONR) enhanced the nanoreaction greatly to produce gold nanoparticles (AuNPs) that exhibited strong surface plasmon resonance (SPR) absorption (Abs) at 550 nm and resonance Rayleigh scattering (RRS) at 550 nm. Upon addition of the peptide of human chorionic gonadotropin (hCG), the peptide ...

BACKGROUND Rapid response systems (RRSs) aim to identify and rescue hospitalized patients whose condition is deteriorating before respiratory or cardiac arrest occurs. Previous studies of RRS implementation have shown variable effectiveness, which may be attributable in part to barriers preventing staff from activating the system. OBJECTIVE To proactively identify barriers to calling for urge...

UNLABELLED We studied lung function in children with and without asthma receiving anesthesia with sevoflurane. Fifty-two children had anesthesia induced with sevoflurane (up to 8%) in a mixture of 50% nitrous oxide in oxygen and then maintained at 3% with children breathing spontaneously via face mask and Jackson-Rees modification of the T-piece. Airway opening pressure and flow were then measu...
