Information retrieval applications are are good candidates for hosting in a cloud infrastructure. CiteSeerx, a digital library and search engine, was built with the goal of efficiently disseminating scientific information and literature over the web. The framework for CiteSeerx, an application of the SeerSuite software, was designed with a focus on extensibility and scalability. Its loosely cou...

Recent advances in computing, communications and data storage have led to an increasing number of large digital libraries, which are nowadays publicly available on the Internet. However, to find required information in that enormous mass of data becomes very difficult. In this demo we present a digital library search engine that combines efforts of the AMIS and DMW research projects, each cover...

This paper describes a novel fixturing system for the automated assembly and disassembly of aero engine components. The proposed system has the ability to automatically reconfigure for a number of different parts and allows the precise control and monitoring of its clamping positions and exerted clamping forces. Aspects of the control software of this system, like the graphical user interface (...

Collocations whose semantic content is not or only partially composed from the semantic content of their parts are often viewed as problematic for generation. In this paper a tactical generator combining FUF as the generation engine and HPSG as the grammar framework is presented. It is shown, that the lexicon driven approach to syntactic and semantic processing is well-suited for the generation...

Substitution of a metallic diaphragm for the power piston of a Stirling engine is shown to be a promising approach to transmitting power for a heat-actuated heat pump through a hermetic seal. Hydraulic fluid under high pressure transfers the power from the diaphragu to the compressor plunger, which is balanced by a counterweight. The discussion is divided into three parts which deal with the in...

A White-cell-based binary optical true-time-delay device has two parts: the controller, or switching engine, and the delay elements. Here we discuss in detail the design of both glass blocks and lens trains as delay elements. Glass blocks can be used in our design for delays ranging from one to a few hundred picoseconds. Lens trains are suitable for longer delays. We also analyze the loss assoc...

in this study the performance and emissions characteristics of a heavy-duty, direct injection, compression ignition (ci) engine which is specialized in agriculture, have been investigated experimentally. for this aim, the influence of injection timing, load, engine speed on power, brake specific fuel consumption (bsfc), peak pressure (pp), nitrogen oxides (nox), carbon dioxide (co2), carbon mon...

nowadays, due to the increasing power of diesel engines, especially heavy duty diesel engines, and increasing gas pressure inside the combustion chamber, the forces acting on the engine bearings have dramatically raised. on the other hand, becaus eof the competition in the market, it is necessary to increase the engine bearing life and reduce its failure as much as possible. the engine bearings...
