Abstract A novel trajectory tracking strategy is developed for a double actuated swing in a hydraulic construction robot.Specifically, a nonlinear hydraulic dynamics model of a double actuated swing is established, and a parameter adaptive sliding mode control strategy is designed to enhance the trajectory tracking performance.When an object is gra
Order picking is a critical and labour-intensive warehouse management operation that involves removing items from storage locations to fulfil customer orders.This paper analyses a new order-picking problem based on the real case of a Canadian shoe manufacturer characterised by a warehouse with random storage, where different product types can be as
Rapid cooling is one of the most important factors in maintaining initial egg quality.Tests conducted on a poultry ranch in southern Main Tub Water Seal California show that the time required for cooling eggs is greatly affected by the container in which they are packed.Best cooling conditions are obtained when the egg has the least packaging or a
In this paper, Coaster Holder we describe an approach to database preference queries based on the notion of outranking, suited to the situation where preferences on different attributes are not commensurable.This model constitutes an alternative to the use of Pareto order whose main drawback is to leave many tuples incomparable in general.Even thou
