An integrated optimization framework, including location assignment under grouping class-based storage policy and schedule of dual shuttle cranes, is offered by presenting a new optimization programming model. The objective functions, which are considered at this level, are the minimization of total costs and energy consumption. Scheduling of dual shuttle cranes among specified locations, which...

Interest points on the building façade are the basic element for 3-D building modeling and texturing. Grouping these points to the same or separate buildings is a fundamental process for establishing building models and detecting building boundaries. The grouping process is generally achieved by analyzing the geometric relation and the distances between the points in the object space, which req...

This paper addresses a commercial districting problem arising in the bottled beverage distribution industry. The problem consists of grouping a set of city blocks into territories so as to maximize territory compactness. As planning requirements, the grouping seeks to balance both number of customers and product demand across territories, maintain connectivity of territories, and limit the tota...

We consider multi-input multi-output (MIMO) Rayleigh block fading channels and examine the V-BLAST architecture proposed for point-to-point communications over such channels. The results obtained are also applicable to the MIMO multiaccess channel. We derive the outage probabilities or upper bounds to outage probabilities, obtained with the optimum decoder and various successive decoders, namel...

Owing to the advantages of low cost, flexibility, and transmission characteristics air–ground (AG) channels, using unmanned aerial vehicle (UAV) as mobile relay assist wireless communication has received significant interest recently. A green non-orthogonal multiple access (NOMA)-based multi-UAV-enabled relaying system with different rate requirements is proposed here. To improve energy efficie...

In this paper, we study user grouping, precoding design, and power allocation for multiple-input multiple-output (MIMO) nonorthogonal multiple access (NOMA) systems. An optimization problem is formulated to the maximize sum rate under a transmit constraint at base station constraints on users, which are nonconvex combinatorial thus very challenging solve. To tackle problem, carry out in two ste...

hypotheses may grow exponentially. To address this problem, it is clear that more a priori information is needed. One This paper addresses the problem of matching line segments in two images from a sequence of images. We propose a new way to incorporate such information is to make implicit algorithm that employs relaxation labeling to integrate the perassumptions about objects in motion, such a...

Quantity of organization in complex networks here is measured as the inverse of the average sum of physical actions of all elements per unit motion multiplied by the Planck’s constant. The meaning of quantity of organization is the number of quanta of action per one unit motion of an element. This definition can be applied to the organization of any complex system. Systems self-organize to decr...
