The effects of link annotations on user search performance in hypertext environments having deep (layered) and shallow link structures were investigated in this study. Four environments were tested—layered-annotated, layered-unannotated, shallow-annotated, and shallow-unannotated. A single document was divided into 48 sections, and layered and unlayered versions were created. Additional version...

Software structuring techniques aim to make systems easier to develop and maintain, increasing their quality. Aspect-Oriented Software Development (AOSD) and Software Architectural Styles are examples of such techniques. In spite of all the benefits of such structuring techniques, it is not always easy or even advantageous to integrate two or more of these techniques. For example, the effects o...

This paper presents a color-resolution layered coding scheme for a scalable video delivery system which operates over heterogeneous networks and distributes real-time streaming video to diverse types of video clients running on devices which range from high-powered workstations to mobile computing devices such as handheld and palm-sized computers. The layered coding scheme employs a wavelet tra...

Inference of ancestry from genetic data is a fundamental problem in computational genetics, with wide applications in human genetics and population genetics. The treatment of ancestry as a continuum instead of a categorical trait has been recently advocated in the literature. Particularly, it was shown that a European individual’s geographic coordinates of origin can be determined up to a few h...

This paper describes design of integrated system for humanoid robotics that consists of three key components, 1) 3D vision, 2) motion planning and 3) bipedal control. Layered system design is adopted to achieve concurrency as well as small latency. Then implementation by using our humanoid type robot H7 and experiments by this architecture are also described. The H7 is expected to be a common t...

Given an uncountable regular cardinal κ, a partial order is κstationarily layered if the collection of regular suborders of P of cardinality less than κ is stationary in Pκ(P). We show that weak compactness can be characterized by this property of partial orders by proving that an uncountable regular cardinal κ is weakly compact if and only if every partial order satisfying the κ-chain conditio...

Layered representations, originally introduced in 7] are important in several applications. Speciically, they are very appropriate for object tracking, object manipulation and content-based scalability which are among the main functionalities of the future standard MPEG-4 2, 3]. A robust representation of moving images based on layers has been presented in 5]. One of the most crucial stages in ...

This paper describes a high-level approach for our improved Cloud Computing Adoption Framework update 1 (CCAF 1.1), which emphasizes on the security policies, recommendations, techniques and technologies to be updated in our framework. Motivation, background, security overview and recent attack methods have been discussed. We propose a solution based on arising needs to improve current Cloud se...

this paper investigates the lateral vibration of single-layered graphene sheets based on a new theory called doublet mechanics with a length scale parameter. after a brief reviewing of doublet mechanics fundamentals, a sixth order partial differential equation that governs the lateral vibration of single-layered graphene sheets is derived. using doublet mechanics, the relation between natural f...

Accessing computer resources from off campus has been a continuing problem for both students and faculty, and this problem has been exacerbated by the growth of our graduate program. A multi-layered remote authentication system has been created for use by students and faculty providing the ability to telecommute and gain remote access to these resources. Security concerns have also been address...
