This paper presents a new way for mobile robots’ path planning which is based on the Evolutionary Artificial Potential Fields(EAPF) approach. The APF theory is a traditional method to plan path for a robot. The Evolutionary APF aims at helping a robot jump out of the local minimum point. Using a virtual goal to produce extra force and fixing the direction of the repulsive force are combined to ...

We present in this paper a sequential Monte Carlo methodology for joint detection and tracking of a multiaspect target in image sequences. Unlike the traditional contact/association approach found in the literature, the proposed methodology enables integrated, multiframe target detection and tracking incorporating the statistical models for target aspect, target motion, and background clutter. ...

In this paper, based on a benchmark the performance of Unified Power Quality Conditioner (UPQC), improvement is presented comparatively by using Proportional Integrator (PI)-type controllers optimized Grey Wolf Optimization (GWO) computational intelligence method, fractional order (FO)-type differential and integral calculus, PI-type controller in tandem with Reinforcement Learning—Twin-Delayed...

BACKGROUND Studies have shown that the barks and roots of some Apocynaceae species have anticancer and antimalarial properties. In this study, leaf extracts of five selected species of Apocynaceae used in traditional medicine (Alstonia angustiloba, Calotropis gigantea, Dyera costulata, Kopsia fruticosa and Vallaris glabra) were assessed for antiproliferative (APF) and antiplasmodial (APM) activ...

UNLABELLED This work describes the coffee leaf apoplastic proteome and its modulation by the greenhouse conditions. The apoplastic fluid (APF) was obtained by leaf vacuum infiltration, and the recovered proteins were separated by 2-DE and subsequently identified by matrix assisted laser desorption/ionization time of flight-mass spectrometry, followed by homology search in EST coffee databases. ...

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...
