The design and implementation of a monolithic micro electro mechanical systems (MEMS)-based gas sensor virtual component is described. The gas sensor virtual component encloses the sensor and its associated analog circuitry into a digital shell so that all interface connections to the virtual component are digital. The system architecture supports an array of gas sensor elements. System respons...

because of large-scale dry regions, salt marsh monitoring is necessary using of remote sensing data's. the aim of this study is to monitor salt kashan using of satellite data's processing. therefore, the satellite images of lissiii sensor were used. initially, the technique of color composite images envi4.8 software was used to clearly distinguish salt. then, principal component analy...

This paper describes development of a simulator for airborne altimetric LiDAR. Main aim of simulator is to replicate the functioning of LiDAR sensor and generate data for a given terrain with specified parameters of the sensor and trajectory. The simulator has three components: 1) Terrain component, 2) Sensor component, and 3) Platform component. The terrain component is formed using multiple m...

Current rotorcraft gas turbine engines typically use titanium alloys and steel for the compressor section single-crystal nickel superalloys hot-section stator vanes rotor blades. However, these material selections are rapidly changing due to increased requirements of power-density efficiency. Future U.S. Army will be using ceramic matrix composites many high temperature engine components their ...

Signal transduction by a traditional two-component system involves a sensor protein that recognizes a physiological signal, autophosphorylates and transfers its phosphate, and a response regulator protein that receives the phosphate, alters its affinity toward specific target proteins or DNA sequences and causes change in metabolic activity or gene expression. In some cases the sensor protein, ...

The Rcs two-component pathway is involved in the regulation of capsule production in Escherichia coli. RcsC is predicted to be the sensor component of this two-component pathway, and in this study we present the first genetic data that support the role of RcsC as a hybrid sensor kinase.

In this study, a multi nanosensor was fabricated for the simultaneous detection of carbon dioxide, methane, ethanol, and ammonia gases, and its electrochemical response to various concentrations of these gases were investigated. In order to fabricate this multi nanosensor, in the first phase, the Graphene-Oxide/Polyaniline (GO/PANI) nanocomposite was synthesized. Chemical ...

Clustering is an important research topic for wireless sensor networks (WSNs). A large variety of approaches has been presented focusing on different performance metrics. Even though all of them have many practical applications, an extremely limited number of software implementations is available to the research community. Furthermore, these very few techniques are implemented for specific WSN ...
