scanning impedance microscopy (sim) is one of the novel scanning probe microscopy (spm) techniques, which has been developed to taking image from sample surface, providing quantitative information with high lateral resolution on the interface capacitance, and investigating the local capacitance–voltage (c–v) behavior of the interface and ac transport properties. the sim is an ordinary afm equip...
This paper discusses open phase faults, which can happen in a system grid-converter-motor drive, and measures to properly handle this type of fault. The authors provide classification algorithms used for the detection loss explain distinctive features each group methods. They review existing algorithms, are based on analysis current signals, discuss their pros cons suggest possible areas usage ...
Vibration signals were measured in a lab-scale fluidized bed to investigate the changes in particle sizes. Experiments were carried out in the bed with a different mass fraction of coarser particles at different superficial gas velocities, and probe heights. The S-statistic test evaluates the dimensionless squared distance between two attractors reconstructed from time series of vibration signa...
Introduction: In this paper, a novel complexity measure is proposed to detect dynamical changes in nonlinear systems using ordinal pattern analysis of time series data taken from the system. Epilepsy is considered as a dynamical change in nonlinear and complex brain system. The ability of the proposed measure for characterizing the normal and epileptic EEG signals when the signal is short or is...
Global Maritime Distress Safety System (GMDSS) is one of the best and most efficient systems for emergency. The systems have been developed to provide mariners global communications and locating network. This system includes land stations for all INMARSAT services to reporting at sea, and so far using this communication system, in marine emergency situations has helped rescue thousands of lives...
This paper reports on the analysis of the signals sent by accelerometers fixed on the axles of a vehicle which passes over a bridge. The length of the bridge is divided into some parts and the transmissibility measurement is applied to the signals recorded by two following instrumented axles. As the transmissibility procedure is performed on the divided signals, the method is called Short Time ...
Research related to diver safety, navigation and monitoring has been identified as crucial for advancing diving activities. These issues are usually dealt with by pairing up divers and adopting well defined rules for diving operations to reduce the chance of accidents. However, during more challenging dives (such as technical dives) these procedures may not be sufficient to ensure almost accide...
We provide updates to the Kepler planet candidate sample based upon nearly two years of high-precision photometry (i.e., Q1–Q8). From an initial list of nearly 13,400 threshold crossing events, 480 new host stars are identified from their flux time series as consistent with hosting transiting planets. Potential transit signals are subjected to further analysis using the pixel-level data, which ...
