The NB-IoT (NarrowBand-Internet of Things) radio technology is now widely implemented by mobile phone network operators to support the communication IoT devices such as smart meters, insurance black boxes for cars, connected waste bins, bicycles. In present work, some LTE800 cells different implementing in guard band mode have been investigated. signals, consisting a PRB (Physical Resource Bloc...

BACKGROUND Magneto-acoustic tomography with current injection involves using electrical impedance imaging technology. To explore the potential applications in imaging biological tissue and enhance image quality, a new scan mode for the transducer is proposed that is based on translational and circular scanning to record acoustic signals from sources. METHODS An imaging algorithm to analyze th...

Dynamic Time Warping (DTW) is a time domain based method and widely used in various similar recognition and data mining applications. This paper presents a phase compensation based DTW to process the motor current signals for detecting and quantifying various faults in a two-stage reciprocating compressor under different operating conditions. DTW is an effective method to align up two signals f...

The objective of this study is development of driver’s sleepiness using Visually Evoked Potentials (VEP). VEP computed from EEG signals from the visual cortex. We use the Steady State VEPs (SSVEPs) that are one of the most important EEG signals used in human computer interface systems. SSVEP is a response to visual stimuli presented. We present a classification method to discriminate between...

In this notewe give a new effective proofmethod for the equivalence of the notions of testability and nondeterministic testability for uniform hypergraph parameters. We provide the first effective upper bound on the sample complexity of any nondeterministically testable r-uniform hypergraph parameter as a function of the sample complexity of its witness parameter for arbitrary r. The dependence...

Switched-capacitor (SC) circuits are analog discretetime signal processing circuits. At the front-end of these circuits, the continuous-time input signal has to be transformed into a discrete-time version. In order to optimize the settling speed of the SC circuit by creating step-input settling responses, the input interface circuit has to transform the continuous-time input signal into a unifo...
