Post-translational modifications of the water-soluble human lens crystallins from young adult donors were identified and located using electrospray ionization mass spectrometric analysis intact proteins fast atom bombardment spectrometry enzymatic digests. Peptides corresponding to all sequences alpha A-, B-, beta B2-crystallins found, permitting entire be searched for modifications. The major portions these three not modified. Modifications A-crystallin that detected included 2...
Autonomous vehicle (AV) systems must be comprehensively tested and evaluated before they can deployed. High-fidelity simulators such as CARLA or LGSVL allow this to done safely in very realistic highly customizable environments. Existing testing approaches, however, fail test simulated AVs systematically, focus on specific scenarios oracles (e.g., lane following scenario with the "no collision" requirement) lack any coverage criteria measures. In paper, we propose <inline-formula...
Development of lightweight deep learning crack detection method is essential for the future deployment mobile device-based structure inspection. The primary challenge involves analysis and extraction features from narrow cracks, typically 3–6 pixels wide, which are often obscured by noise such as water stains shadows. model should also maintain high accuracy while ensuring low computational complexity a minimal number parameters. To this end, paper proposes YOLO v5-DE (Dense Feature...
This paper studies the statistical analysis for alarm signals in order to detect whether two are correlated. First, a similarity measurement, namely, Sorgenfrei coefficient, is selected among 22 coefficients binary data literature. The selection based on desired properties associated with specialities of signals. Second, distribution so-called correlation delay shown be indispensable and effective detection correlated alarms. Finally, novel method alarms proposed coefficient delay. Numerical...
Alarm systems play critically important roles for the safe and efficient operation of industrial plants, but they often suffer from too many nuisance alarms. Deadbands are widely used in alarm to reduce number This paper formulates an index determine whether deadbands suitable removing alarms analog signal, proposes a method design deadband width. First, is defined two metrics, namely, normalized durations deviations. If larger than 45°, as indicated by hypothesis test, then associated with...
Abstract In order to solve the problem of unclear relationship between aerodynamic characteristics aircraft engine fan blade airfoil (such as leading edge radius and wedge angle) its resistance foreign body damage (FOD) sensitivity analysis under data redundancy conditions that cannot be achieved by traditional methods, a method based on K-means clustering was proposed. First, simulated impact tests were conducted TC4 titanium alloy specimens using an air cannon. The step-loading test used...
Alarm trippoints are critical parameters of industrial alarm systems in process industries. This paper proposes a method to design optimal for univariate analog variables based on so-called probability plots. An plot involves four statistics, namely, the transition and averaged step toward an trippoint, away from trippoint. Theoretical expressions statistics developed Markov chain theory. The estimated with proper determination quantification intervals transferring discrete state variables....
Abstract To study the influence of different water–binder ratios on corrosion, permeability, and freezing properties concrete, we produced strengths concrete with respective 0.32, 0.38, 0.50, 0.66. The corrosion resistance was studied via three methods: full immersion, half dry wet cycles. impermeability frost were tested analyzed. test results show that modes in order from strong to weak cycles, soaking, soaking. relative dynamic elasticity modulus freeze–thaw index used evaluate based...
Despite remarkable growth in penetration of renewable energy resources power grids, most recovery and restoration strategies cannot fully harness the potentials such due to their inherent uncertainty stochasticity. We propose a resilient disaster scheme unlock flexibility distribution system (DS) through reconfiguration practices efficient utilization mobile sources (MPS) across system. A novel optimization framework is proposed model MPSs dispatch while considering set scenarios capture...

This paper proposes a method to search similar data segments in order assist plant operators analyzing the root causes of an occurring alarm for pivot process variable. The proposed is composed by three major steps: (i) piece-wise linear representations are applied obtain increasing, decreasing and steady trends all related variables; (ii) density peaks cluster analysis used historical with qualitative trends; (iii) most found when variable currently on state. An industrial example provided...
This paper studies the correlation analysis for bivariate alarm signals in order to indicate whether two are correlated, and their cause-effect direction if they correlated. First, seven similarity coefficients selected as measurements binary data, consideration of specialities signals. The upper bounds these theoretically established independent Second, distribution a so-called delay is shown be indispensable effective analysis. Finally, novel method proposed based on ratio coefficient...
This brief proposes an approach to estimate static gains of dynamic models for automatic generation control systems in coal-fired power units. The main idea is infer from amplitude changes model inputs and outputs finite-time ramp responses. First, input output time sequences are approximated by a few straight lines as piecewise linear representations. Second, responses detected the data segments where simultaneously move along with significant changes. Third, estimated obtained solving...
