Introduction: The noise could affect some aspects of human health, including the cognitive performance. In addition to sound pressure level and exposure time, the psychoacoustic features of noise may cause destructive effects on humans. A few recent studies have been conducted on effect of sound quality on cognitive performance. This study aims to find the noise loudness and sharpness levels as...

The paper proposes a novel multi-area state estimator based on wide area measurements where only boundary buses are considered in the coordination level. The power injection measurements are not used during the coordination level reducing the number of states and therefore size of the problem. Instead, a set of pseudo-measurements are included whenever a power injection measurement is available...

in recent years noise has been well known as an environmental pollution. particularly its effects will be more serious in some environments including hospitals which patients need a calm and peaceful condition. this study aims to evaluate hospitals noise pollution level. this study is a cross-sectional study. noise measurements were made in all hospital wards in a workday and weekend from 8 to ...

In deep-submicron technologies the primary component of delay is shifting from logic gates to the interconnect network. Buses can no longer be considered as a set of independent lines that don’t interact. A more appropriate model would treat the bus as a distributed system, where a transition on a line would affect adjacent lines as well. However, the transitions on the buses can be grouped int...

This paper presents the conception, design, implementation and testing of innovative software architectures and software development processes for rapid prototyping of automated transit buses. Our work is motivated by demonstrations of automated transit bus technology in the context of Bus Rapid Transit (BRT) systems. Mission handling and safety issues are handled via a three-layer hierarchical...

Power flow computations are important for operation and planning of the electricity grid, but computationally expensive because nonlinearities size system equations. Linearized methods reduce computational time often have disadvantage that they not applicable to general grids. In this paper we propose a novel linearized power (LPF) technique is able handle PQ- PV-buses, works on both transmissi...
