The artificial potential field (APF) method is a classical path planning algorithm for mobile robots. Although the simple, it still has some defects, which limit scope of its application. In this paper, we propose an adaptive repulsive function to solve problem, goals nonreachable with obstacles nearby (GNRON). Then, (AAPF) combined rolling window used local-minima problem and can be in dynamic environment.

There is a surprising paucity of studies investigating the potential mechanism SKA3 in progression and prognosis kidney renal papillary cell carcinoma (KIRP).We used TCGA other databases to analyze expression, clinical value, mechanisms KIRP patients. We also explored therapeutic agents for through GSCALite.SKA3 mRNA expression was significantly upregulated area under curve 0.792 (95% CI 0.727-0.856). Increased related shorter overall survival, disease-specific survival progression-free...
An air turbine starter (ATS) is used to start the aero-engine before an aircraft takes off, which plays a significant role in reliable operation of and critical flight security, so it vital monitor health predict remaining useful life (RUL) for ATS.
