Performance Evaluation of Web Information Systems [PDF]

open access: yes, 2010
The quality of web information systems is closely related with their users’ expectations. In order to create good quality systems, web designers should understand how users perceive service quality of various performance attributes such as security, usability and information quality, and which ones they value the most.

High-resolution land surface modelling over Africa: the role of uncertain soil properties in combination with forcing temporal resolution [PDF]

open access: yesHydrology and Earth System Sciences
Land surface modelling runs conducted with the Community Land Model version 5.0 (CLM5) over Africa at 3 km resolution were carried out, and we assessed the impact of different sources of soil information and different upscaling strategies for the soil ...

Clock performance as a critical parameter in navigation satellite systems [PDF]

open access: yes, 1978
The high performance of available oscillators has permitted the development of invaluable navigation and geodetic satellite systems. However, still higher performance oscillators would further improve the accuracy or flexibility of the ...

Performance Analysis of Shaft Generator Systems

open access: yesIEEJ Transactions on Industry Applications, 1998
A shaft generator system supplies electrical power required in a ship by using a part of the power produced by the main engine. Since the speed of the main engine can vary over a wide range, an externally commutated thyristor inverter, which has high reliability, is generally used to produce ac power with constant voltage and frequency.

Performance Aware Reconfiguration of Software Systems [PDF]

open access: yes, 2010
In this paper we address the problem of building a scalable component-based system by means of dynamic reconfiguration. Specifically, we consider the system response time as the performance metric; we assume that the system components can be dynamically reconfigured to provide a degraded service with lower response time. Each component operating at one

Distributed performance analysis of heterogeneous systems [PDF]

open access: yes49th IEEE Conference on Decision and Control (CDC), 2010
In the study of distributed systems, it is of fundamental interest to understand how specifications on local components and interconnections influence global properties of the system. In this paper, we consider linear continuous time systems described by sparse matrices. Properties of interest are stability and quadratic performance specifications such

Dynamic Response Analysis Method of a High-Strength RC Beam Subjected to Long-Duration Blast Loading

open access: yesBuildings
An analysis method of normalized pressure–impulse (P-I) diagrams related to the ductility ratio of structural components is proposed, to quickly estimate the dynamic response of high-strength reinforcement concrete (RC) beams subjected to long-duration ...

Performance evaluation of ductless personalized ventilation in comparison with desk fans using numerical simulations [PDF]

open access: yes, 2020
The performance of ductless personalized ventilation (DPV) was compared to the performance of a typical desk fan since they are both stand-alone systems that allow the users to personalize their indoor environment.
