In recent years,Simultaneous Localization And Mapping(SLAM)technology has prevailed in a wide range of applications,such as autonomous driving,intelligent robots,Augmented reality(Ar),and Virtual reality(Vr).Multi-sensor fusion using the most popular three types of sensors(e.g.,visual sensor,liDAr sensor,and IMU)is becoming ubiquitous in SLAM,in part because of the complementary sensing capabilities and the inevitable shortages(e.g.,low precision and long-term drift)of the stand-alone sensor in challenging *** this article,we survey thoroughly the research efforts taken in this field and strive to provide a concise but complete review of the related ***,a brief introduction of the state estimator formation in SLAM is ***,the state-of-the-art algorithms of different multi-sensor fusion algorithms are *** we analyze the deficiencies associated with the reviewed approaches and formulate some future research *** paper can be considered as a brief guide to newcomers and a comprehensive reference for experienced researchers and engineers to explore new interesting orientations.

The adsorb model of formic acid on NaX derived from TpD was discussed. It was showed that the adsorb sites were various exposed framework O2- centers bearing different basic intensity and spatial resistance. The h-peak was attributed to O2- near S-III in supercage and l-peak to O2- near S-II in beta-cage of faujusite zeolite. The model can explain the experimental results. Meanwhile, a relative standard of basic intensity based on TpD of formic acid was founded.

This paper is concerned with the uniformity of a certain kind of resolvable incomplete block (rIB for simplicity) design which is called the prIB design here. A sufficient and necessary condition is obtained, under which a prIB design is the most uniform in the sense of a discrete discrepancy measure, and the uniform prIB design is shown to be connected. A construction method for such designs via a kind of U-type designs is proposed, and an existence result of these designs is given. This method sets up an important bridge between prIB designs and U-type designs.

The interfacial structure between the room-temperature ionic liquid, 1-butyl-3-methyl-imidazolium hexafluorophosphate (BMIM+/pF6-) and rutile (110) surface is simulated by classical molecular dynam-ics simulation, aiming to model a crucial constituent of the electrolyte/semiconductor interface. The simulation results show several enhanced layers forming in the interfacial region, especially for the anions. A well ordered double layering structure of the ions is also observed in the interfacial region. The cations are found to organize themselves in a parallel alignment with respect to the TiO2 slab, with an obvious elongation of the side chains.
