Optimum laminate configuration for minimum weight of filament–wound laminated conical shells subject to buckling load constraint is investigated. In the case of a laminated conical shell the thickness and the ply orientation (the design variables) are functions of the shell coordinates, influencing both the buckling load and its weight. These effects complicate the optimization problem consider...

In this study, we discuss the capacitated facility location-allocation problem with uncertain parameters in which the uncertainty is characterized by given finite numbers of scenarios. In this model, the objective function minimizes the total expected costs of transportation and opening facilities subject to the robustness constraint. To tackle the problem efficiently and effectively, an effici...

Recent advancement in web services plays an important role in business to business and business to consumer interaction. Discovery mechanism is not only used to find a suitable service but also provides collaboration between service providers and consumers by using standard protocols. A static web service discovery mechanism is not only time consuming but requires continuous human interaction. ...

For random systems subject to a constraint, the microcanonical ensemble requires constraint be met by every realisation ("hard constraint"), while canonical only on average ("soft constraint"). It is known that for graphs topological constraints breaking of equivalence may occur when size graph tends infinity, signalled non-vanishing specific relative entropy two ensembles. We investigate what ...

This letter is concerned with the attitude control of a quadrotor unmanned aerial vehicle (UAV) subject to input constraint, constraint and model uncertainty. Firstly, we construct an auxiliary system eliminate adverse impact saturation. Secondly, introduce nonlinear state-dependent function deal directly. Thirdly, neural network utilized identify unknown terms in system. Finally, help backstep...

In this paper, a new formulation along with numerical solution for the problem of finding a point-to-point trajectory with maximum load carrying capacities for flexible manipulators is proposed. For rigid manipulators, the major limiting factor in determining the Dynamic Load Carrying Capacity (DLCC) is the joint actuator capacity. The flexibility exhibited by light weight robots or by robots o...

In this paper, we consider the problem of assigning tasks to operators according to a large set of constraints that include time sensitivity and travel optimization. Our practical instance of this problem combines computational complexity (scheduling the tasks for one technician is NP-hard and little is known about getting a solution [CK92]) and size (around 20000 tasks stored in a database). W...

This paper deals with the leader-follower formation control problem while communication constraint in data transmitting is considered. From a practical point of view, we study the case in which unmanned vehicles are subject to the limited sensing, and communication is of a particular interest. A three-dimensional formation flight of multi-unmanned aerial vehicles with leader-follower configurat...

Onofri [Onofri, A. 2018. ‘The Publicity of Thought.’ Philosophical Quarterly 68 (272): 521–541.] proposes an individuation criterion for thoughts that purports to satisfy both shareability (the notion different thinkers, or a single thinker at times, can and generally do think type-identical thoughts) Frege's constraint (according which two are if it is possible rational subject endorse one whi...
