Presence in Collaborative Virtual Environments (CVEs) can be defined into personal presence and co-presence. Personal presence is having a feeling of "being there" in the CVE yourself. Co-presence is having a feeling that ...

A prototype presentation system base is described. It offers mechanisms, tools, and ready-made parts for building user interfaces. A general user interface model underlies the base, organized around the concept of a ...

This research will develop a methodology for designing user interfaces for general-purpose interactive systems. The central concept is the presentation, a structured pictorial or text object conveying information about ...

A method is presented for generating shaped command inputs which significantly reduce or eliminate endpoint vibration. Desired system inputs are altered so that the system completes the requested move without residual ...

Hydraulic fracturing is an effective well stimulation technique which is introduced in the 1950s and widely used in the oil and gas industry. Most of the works about hydraulic fracture assumed that the fracture is symmetric ...

Hydraulic fracturing has been an effective technique to stimulate damaged wells or wells producing from low-permeability formation. It has been established that the orientation of a hydraulic fracture is perpendicular to ...

A composite reservoir is one with multiple lateral compartments; each having distinct rock and fluid properties separated by geologic discontinuities. Geologically, composite reservoirs separated by leaky faults are rife ...

This study investigated transient flow response of heavy oil that exhibit Bingham fluid characteristics. Four wellbore conditions in naturally fractured reservoirs were considered which include horizontal well, hydraulically ...

New equations for bilinear, formation linear and pseudo-radial flow regimes in an infinite commingled fractured multilayered reservoir have been developed. The equations have been extended to Tiab’s Direct Synthesis Technique ...

This dissertation presents an overview of the research work with the above caption. This research is divided into five major sections or parts. Part one deals with interfacial adhesion studies of the layers relevant to ...

Recent research in linguistic analysis of presuppositions has provided numerous indications of the role of presupposition in lexical analysis. Still others have argued there is no distinction between meaning and the ...

Pretty-printing is the conversion of the list structure to a readable format. This paper outlines the computational problems encountered in such a task and documents the current algorithm in use.

Chemical method is the most efficient and flexible method of hydrate control in offshore operations. In recent times, polymers and surfactants have been used to influence the kinetics of hydrate growth and coagulation. ...

The next generation of artificial intelligence programs will require the ability to organize knowledge as groups of active objects. Each object should have only its own local expertise, the ability to operate in parallel ...

R is a text formatter. The information in this primer is meant to explain, in simple English, the basic commands needed to use R. Input for R is prepared on computer systems using a text editor. Which editor employed ...

TEX is our latest text formatter. It is designed specifically for technical text (e.g., mathematics), and produces much higher quality output than other formatters previously available. Donald Knuth designed TEX at Stanford ...

This paper describes the current design for the Act-1 computer programming language and describes the Actor computational model, which the language was designed to support. It provides a perspective from which to view ...
