This study aims to validate a banking service redundancy model for Sepah Bank to assess the impact of redundant banking services on operational efficiency, customer experience, and technological integration. The research employs a mixed-methods approach, integrating both qualitative and quantitative analyses. The qualitative phase involves a meta-synthesis of existing literature on banking service redundancy, digital banking optimization, and financial risk management. The quantitative phase utilizes survey data collected from 384 Sepah Bank customers and experts in banking service management.

Abstract Motivation Temporal biomarker discovery in longitudinal data is based on detecting reoccurring trajectories, the so-called shapelets. The search for shapelets requires considering all subsequences in the data. While the accompanying issue of multiple testing has been mitigated in previous work, the redundancy and overlap of the detected shapelets results in an a priori unbounded number of highly similar and structurally meaningless shapelets. As a consequence, current temporal biomarker discovery methods are impractical and underpowered. Results We find that the pre- or post-processin

The validity of complexity simplifications for proteins with different structural features may be different. In this paper, the simplification for proteins is studied using the ratios of successful prediction of structural class under a presumed amino-acid-grouping scheme with a composition-coupled method. It is found that for the α-class proteins, a two-letter alphabet may cover the degree of freedom to characterize the complexity of the class; for the β-class proteins, a 7-letter alphabet might indicate the minimal number of residue types to reconstruct the class feature of the natural prote

This paper presents a robust model-based technique to detect multiple faults in permanent magnet synchronous motors (PMSMs), namely inter-turn short circuit (ITSC) and encoder faults. The proposed model is based on a structural analysis, which uses the dynamic mathematical model of a PMSM in an abc frame to evaluate the system’s structural model in matrix form. The just-determined and over-determined parts of the system are separated by a Dulmage–Mendelsohn decomposition tool. Subsequently, the analytical redundant relations obtained using the over-determined part of the system are used to for

The directions for improving the efficiency of providing remote video services using the aviation info-communication segment in the process of support and decision-making in critical infrastructure systems are substantiated. It is justified that in order to localize or eliminate problematic aspects, it is necessary to apply technologies for reducing the bit intensity of the video stream. This will reduce the information load on the network and create conditions for the involvement of redundant code structures. Accordingly, it is necessary to integrate video data compression technologies for on

Summary This paper proposes a method for quantitative integration of seismic(elastic) anisotropy attributes with reservoir-performance data as an aid in characterizing systems of natural fractures in hydrocarbon reservoirs. This method is demonstrated through application to history matching of reservoir performance using synthetic test cases. Discrete-feature-network (DFN) modeling is a powerful tool for developing fieldwide stochastic realizations of fracture networks in petroleum reservoirs. Such models are typically well conditioned in the vicinity of the wellbore through incorporation of c

AbstractThe multivariate statistical techniques of canonical correlation and canonical redundancy analyses were used to assess the population structure of larvae of Sitona hispidulus (F.) in alfalfa field soil. A series of rhizosphere variables was correlated with a series of insect variables that represented the developmental stages of the insect to identify relationships between the insect and rhizosphere. Results indicated that 1st and 2nd-instar larvae were correlated with small root nodules and soil moisture, but not with taproot biomass. Third- and 4th-instar larvae and pupae were not co

In order to enhance the performance of bearing fault diagnosis and classification, features extraction and features dimensionality reduction have become more important. The original statistical feature set was calculated from single branch reconstruction vibration signals obtained by using maximal overlap discrete wavelet packet transform (MODWPT). In order to reduce redundancy information of original statistical feature set, features selection by adjusted rand index and sum of within-class mean deviations (FSASD) was proposed to select fault sensitive features. Furthermore, a modified feature

AlphaFold2 (AF2) is a protein structure prediction program which provides accurate models. In addition to predicting structural domains, AF2 assigns intrinsically disordered regions (IDRs) by identifying regions with low prediction reliability (pLDDT). Some regions in IDRs undergo disorder-to-order transition upon binding the interaction partner. Here we assessed model structures of AF2 based on the annotations in IDEAL, in which segments with disorder-to-order transition have been collected as Protean Segments (ProSs). We non-redundantly selected ProSs from IDEAL and classified them based on

This work proposes an original approach for monitoring and validating discharge measurements on a lateral storm weir. The approach is based on the combined use of a measuring device and a discharge formula. The developed validation procedure first identifies the erroneous measurements and, consequently, the faulty sensor, using information redundancy on the discharged flow. The erroneous measurements are identified using statistical tests on the relative gap between the measured and simulated discharged flows. Secondly, the erroneous discharge flow measurements are corrected by following the c

Although some work using rotations can be found in the literature, this paper, for the very first time, proposes a statistical analysis that justifies the theoretical advantage of measuring rotations.

To mitigate information loss during encoding, skip connections transfer essential feature maps from the encoder to the decoder, preserving structur
