The Art of Reception: Field Visits as Microcosms for Development Interventions of Non‐Governmental Organisations in Uganda

open access: yesJournal of International Development, EarlyView.
ABSTRACT Field visits are common phenomena with non‐governmental organisations in Uganda. During these visits, Ugandan national staff guide visitors on series of meetings and interactions in the field. Following an actor‐oriented approach and drawing on ethnographic data on 14 field visits, this paper understands the field visit as a microcosm for the ...

Involute Helical-bevel Gearing

open access: yesProcedia Engineering, 2015
AbstractThis paper describes helical-bevel gearing (HBG). The helical-bevel gearing commonly includes a cylindrical and a bevel gear. The tooth profiles can be either spur or helical. The involute HBG provides an opportunity to design a broad variety of gear trains, unobtainable by the use of conventional types of gears.

Control System for the Navigation of the Agricultural Robots: A Review

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...

MATHEMATICAL MODELING OF THE PROFILE OF A GEAR CUTTING ROLLING TOOL FOR MACHINING OF NON-INVOLUTE GEAR WHEELS [PDF]

open access: yesFiabilitate şi Durabilitate, 2019
In this article, the relevance of the study of gears with a complex non-involute profile of the tooth flanks is justified. For the subsequent study of non-involute gearings, the task of mathematical modeling of the profile of a gear-cutting rolling ...

Conical Involute Gear. Design of Nonintersecting-Nonparallel-Axis Conical Involute Gear.

open access: yesJSME international journal. Ser. 3, Vibration, control engineering, engineering for industry, 1991
Design of nonintersecting-nonparallel-axis conical involute gears is established. As a result, any conical involute gears which transmit rotational motion between two nonintersecting-nonparallel-axis shafts can be readily designed and made. This design is composed of two methods.
