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 ...

Using a wide range of techniques, including differential scanning calorimetry, X-ray diffraction, Rapid Visco Analyser and Fourier Transform Infera Red Spectroscopy, some physicochemical properties of the starch fraction of six Iranian rice cultivars (Tarom, Tarome Hashemi, Neda, Ramezani, Fajr and Kamfirouzi) [1]were studied and compared. DSC data showed that starch granules of different rice ...

temperature is considered as the basic element of climate and also the environmental limiting factor in lutdesert. in this research, in order to identify the temperature of lut desert located in east of central iran, using remote sensing data, six series of modis sensor images related to june 24th & december 23rd 2002, and also january 22nd, march 22nd, june 22nd & september 24th 2003 w...

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, ...

This work presents a multiparametric system capable of characterizing and classifying white wines according to the grape variety and geographical origin. Besides, it quantifies specific parameters of interest for quality control in wine. The system, known as a hybrid electronic tongue, consists of an array of electrochemical microsensors-six ISFET based sensors, a conductivity sensor, a redox p...

We describe measurements of the rotational component of teleseismic surface waves using an inertial high-precision ground-rotation sensor installed at the Laser Interferometer Gravitational-Wave Observatory (LIGO) Hanford Observatory (LHO). The sensor has a noise floor of 0:4 nrad= Hz p at 50 mHz and a translational coupling of less than 1 μrad=m enabling translation-free measurement of small r...

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 ...

Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...

This paper describes the creation of a Kinetic Pen capable of measuring the six-component force and torque that each of four individual contacts applies to the pen during writing. This was done by staggering the mounting of the four sensors along the long axis of the pen and having an extended arm run from the sensor to the grip site, preventing a clustering of the sensors where the digit tips ...
