BACKGROUND Discovery and validation of protein biomarkers with high specificity is the main challenge of current proteomics studies. Different mass spectrometry models are used as shotgun tools for the discovery of biomarkers. Validation of a set of selected biomarkers from a list of candidates is an important stage in the biomarker identification pipeline. Validation is typically done by tripl...

The switched reluctance motor (SRM) is a promising candidate for electric propulsion systems. In the design process of an SRM, geometry needs to be determined. Using finite element method (FEM) might time-consuming sizing geometry. As alternative, electromagnetic models based on magnetic equivalent circuit (MEC) can utilized SRM. MEC require fewer computational resources and help determine perf...
Abstract Solid rocket motor(SRM) in the whole life cycle, to withstand temperature, gravity, vibration, ignition shock, axial overload and other loads, directly affect of engine. Based on failure mode, mechanism criteria SRM, this paper elaborates explains relevant test numerical simulation methods that storage SRM method analysis, finds under action individual or compound load, column will pro...
Switched reluctance motor (SRM) has many specific advantages and has being gradually used in many kinds of applications. However, because it’s inherently multivariable, strong coupling and highly nonlinear, there are lots of difficulties to build its model. In this paper, the basic operating principle of SRM are briefly introduced firstly, and then numerical and analytical modeling methods are ...
The Switched Reluctance Machine (SRM) based electrical drive systems are ideal for diverse automotive safety-critical applications where the fault tolerance is a basic requirement. The phase independence characteristics of the SRM enable it to operate under partial phase failure conditions also in its classical construction. Its reliability can be improved by applying special fault tolerant des...
SRM drives are the upcoming drives nowadays as these have many advantages such as simplicity , low manufacturing and operating costs, fault tolerance, high torque/inertia ratio and efficiency. The estimation of SRM drive parameters is an important consideration in their field. Many methods are available for this. However the estimation of the optimal parameters is normally preferred. Making use...
This paper presents a new approach to the sensorless control of the switched-reluctance motor (SRM). The basic premise of the method is that an Artificial Neural Network (ANN) forms a very efficient mapping structure for the nonlinear SRM. Through measurement of the phase flux linkages and phase currents the neural network is able to estimate the rotor position, thereby facilitating elimination...

Thus, 1049) has been developed for the Uniif an investigator were to test this SRM National Institute of Standards versity of Pittsburgh smoke toxicity under their laboratory conditions acand Technology, method. SRM 1049 is a nylon 6/6 and cording to the specifications of the UniGaithersburg, MD 20899 has the m...
The Switched Reluctance Motor (SRM) processes great application potential in In-Wheel Motor (IWM) electric vehicles (EV). However the problem of vibration and noise is always a disadvantage of this kind of motor. By utilizing the analytical Fourier fitting method, a convenience method for modeling In-Wheel Switched Reluctance Motor (IW SRM) is proposed for EV applications. And the negative vibr...
