This paper introduces Multi-layered Context Ontology Framework (MLCOF) for comprehensive, integrated robot context modeling and reasoning for object recognition. MLCOF consists of six knowledge layers (KLayer) including rules such as an image layer, three geometry (1D, 2D and 3D geometry) layers, an object layer, and a space layer. For each KLayer, we use a 6-tuple ontology structure including ...

The following propositions are true: (1) Let X be a set and F be a finite family of subsets of X. Then there exists a finite family G of subsets of X such that G ⊆ F and ⋃ G = ⋃ F and for every subset g of X such that g ∈ G holds g 6⊆ ⋃ (G \ {g}). (2) Let S be a 1-sorted structure and X be a subset of the carrier of S. Then −X = the carrier of S if and only if X is empty. (3) Let R be an antisy...

Let A be a set and let B be a non empty set. Observe that B is non empty. In this article we present several logical schemes. The scheme FraenkelInvolution deals with a non empty set A, subsets B, C of A, and a unary functor F yielding an element of A, and states that: B = {F(a); a ranges over elements of A : a ∈ C} provided the parameters have the following properties: • C = {F(a); a ranges ov...

In this review we provide evidence linking relational memory to the hippocampus, as well as examples of sensitive relational memory tasks that may help characterize the subtle effects of nutrition on learning and memory. Research into dietary effects on cognition is in its nascent stages, and many studies have cast a wide net with respect to areas of cognition to investigate. However, it may be...

Background: This review focuses on exploring the concept of the nurse-client relationship as it may be informed by relational ethics. Relational ethics is a new approach to ethical practice in health care and can be a framework for nurses and other health professionals in considering how to help patients and families. Purpose: To review the basic elements of relational ethics prior to summarizi...

Children's ability to modify their drawing procedures changes in their rst decade. Young children make size/shape changes and end-of-sequence inser-tions/deletions of drawing elements. Older children also make middle-of-sequence insertions/deletions and position/orientation changes in drawing elements. Why do modiications occur in this order? We argue that older children's modiications require ...

this study focused on the optimization of al—mg to cuzn34 friction stir lap welding (fslw) process for optimal combination of rotational and traverse speeds in order to yield favorable fracture load using grey relational analysis (gra). first, the degree of freedom was calculated for the system. then, the experiments based on the target values and number of considered levels, corresponding orth...

We present a network based approach to characterize organizational architectures in terms of three domain elements individuals, tasks, and resources. Characterizing the possible relations among these elements results in five relational primitives Precedence, Commitment of resources, Assignment of individuals to tasks, Networks (of relations among personnel) and Skills linking individuals to res...

nowadays, in order to reach minimum production cost in machining operations, various optimization methods have been proposed. since turning operation has different parameters affecting the workpiece quality, it was selected as a complicated manufacturing method in this paper. to reach sufficient quality, all influencing parameters such as cutting speed, federate, depth of cut and tool rake angl...

We present a network based approach to characterize C2 architectures in terms of three domain elements individuals, tasks, and resources. Characterizing the possible relations among these elements results in five relational primitives Precedence, Commitment of resources, Assignment of individuals to tasks, Networks (of relations among personnel) and Skills linking individuals to resources. We d...
