Cylindrical specimen (20 mm x 5 mm, n = 5) consisting of commercially pure titanium ASTM/grade 2 (Ti2 – Dentaurum J.P. Winkelstroeter KGPforzheim, Germany) were casted in the Rematitan system (Rematitan, Dentaurum J.P. Winkerstroeter KG, Pforzheim, Germany) by Vaiazzi Dental Laboratory (São Paulo SP, Brazil). All specimens were cold mounted with epoxy resin and then received the standard metall...

3D printing has the unique ability to produce porous pharmaceutical solid dosage forms on-demand. Although using porosity alter drug release kinetics been proposed in literature, effects of on swellable and erodible have not explored. This study used a model formulation containing hypromellose acetate succinate (HPMCAS), polyethylene oxide (PEO) paracetamol newly developed hot melt droplet depo...

This paper describes n digital control algorithm for a three-phase shunt active power filter (APF) using switching–sliding discrete Fourier transform (SSDFT). Traditionally, APF algorithms use first harmonic detector circuits, which can be implemented the SDFT algorithm. The classical is characterized by long-term stability issues, resulting from numerical errors. Many complex modifications to ...

Inspired by the behaviour of animal populations in nature, we propose a novel exploration algorithm based on Lévy flight (LF) and artificial potential field (APF). The agent is extended to swarm level using APF method through LF search environment. Virtual leaders generate moving steps explore environment mechanism. To achieve collision-free movement an unknown constrained environment, swarm-fo...

Arterioportal fistulas (APFs) are a group of vascular disorders, in which systemic arteries communicate with the portal circulation, presenting as a congenital syndrome or more commonly acquired from iatrogenic instrumentation or abdominal trauma. We report the case of a 58-year-old man who developed ascites without underlying risk factors for portal hypertension, which was attributed to an APF...

In this article we study asymptotic properties of weighted samples produced by the auxiliary particle filter (APF) proposed by Pitt and Shephard (1999a). Besides establishing a central limit theorem (CLT) for smoothed particle estimates, we also derive bounds on the L p error and bias of the same for a finite particle sample size. By examining the recursive formula for the asymptotic variance o...

Use of nonlinear loads at high voltages has increased tremendously in industry. These non-linear loads distort power quality by generating harmonics. Conventional active filters have limitations in high power high voltage systems. Use of multilevel inverter in active filters effectively reduces harmonics in high voltage systems eliminating need of high cost and bulky transformer. This paper pre...

Abstract. Path planning is a key technique used in the operation of bending robots. In this paper, an obstacle-avoidance path-planning method 5 degrees freedom (5 DOF) robot based on improved artificial potential field proposed. Firstly, connecting-rod coordinate system DOF Cartesian established to determine equation motion trajectory robot. Secondly, view problem local minimum (APF) and failur...
