PATH PLANNING FOR INDOOR CONTACT INSPECTION TASKS WITH UAVS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
UAV technology has become a useful tool for the inspection of infrastructures. Structural Health Monitoring methods are already implementing these vehicles to obtain information about the condition of the structure.

Clearance distribution and contact characteristics of misaligned gear couplings considering hob feed path [PDF]

open access: yesScientific Reports
Gear couplings are usually machined using hob and slotting cutter in a predetermined circular path. The tool feed path determines tooth profile. This article designs a new feed path.

Derivation of Path of Contact and Tooth Flank Modification by Minimizing Transmission Error on Face Gear

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2012
This research report discusses how to derive a path of contact on a face gear. A sample was manufactured, in which tooth modification is taken into account, and the sample was investigated as to whether it is robust against alignment errors.

Calculation and experiment of spiral bevel gear by duplex helical method predesigned contact path

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2021
In this paper a method to calculate machine tool setting parameters for spiral bevel gars by duplex helical method is proposed, in which contact path is predesigned. Firstly, machine setting parameters and curvature parameters in reference points of gear

Vertex Contact Representations of Paths on a Grid [PDF]

open access: yesJournal of Graph Algorithms and Applications, 2015
We study Vertex Contact representations of Paths on a Grid (VCPG). In such a representation, the vertices of G are represented by a family of interiorly disjoint grid-paths on a square grid. Adjacencies are represented by contacts between an endpoint of one grid-path and an interior point of another grid-path.

On Contact Graphs of Paths on a Grid [PDF]

open access: yesCoRR, 2018
In this paper we consider Contact graphs of Paths on a Grid (CPG graphs), i.e. graphs for which there exists a family of interiorly disjoint paths on a grid in one-to-one correspondence with their vertex set such that two vertices are adjacent if and only if the corresponding paths touch at a grid-point.

Meshing mechanism considering various combinations of assembly and manufacturing errors on face gear using a transmission-error-controlled curve

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2023
A face gear is typically used in fishing spinning reel mechanism owing to its easy fabrication and good reel handle rotation. As face gears without tooth flank modification are sensitive to assembly errors, the fishing reel sensation becomes unstable in ...

Characteristics and effectiveness of the face gear with transmission-error-controlled curve considering the path of contact (Effect of assembly and manufacturing errors on transmission error)

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2023
The face gear is a crossed gear similar to a hypoid gear. Owing to its compactness and good assemblability, it is used in geared motors and transmissions for helicopters.

Digital contact tracing [PDF]

open access: yesACM SIGCOMM Computer Communication Review, 2020
Since the start of the COVID-19 pandemic, technology enthusiasts have pushed for digital contact tracing as a critical tool for breaking the COVID-19 transmission chains. Motivated by this push, many countries and companies have created apps that enable digital contact tracing with the goal to identify the chain of transmission from an infected ...
