A novel objective wrinkle evaluation method for printed fabrics based on multi-view stereo algorithm

Abstract Traditionally, fabric wrinkle assessment is based on human eyes, which is subjective with the disadvantages of low efficiency and accuracy. In this paper, an objective fabric wrinkle evaluation method was proposed to solve the previous problems due to the subjective evaluation. A self-developed multiple image acquisition system was established for the image capturing of wrinkled fabrics from different direction. Three-dimensional (3D) surface profile of wrinkled fabric was reconstructed by an improved patch-based multi-view stereo vision algorithm. A two-dimensional depth image could be generated directly from the 3D point cloud model, after that, four texture feature parameters were extracted from the depth image using gray level co-occurrence matrix. Finally, these four feature parameters were selected as the input vector and wrinkle grade as the output to form a support vector machine for the objective assessment of fabric wrinkle appearance. Our experimental results indicated that the recognition accuracy of the proposed method and system was more than 90%. The originality of our research is that the wrinkle features based on 3D surface profile reconstructing can avoid interference caused by fabric color and texture and further improve the recognition accuracy of objective evaluation.
Energy-aware task allocation strategy for multi robot system

ABSTRACT This paper proposes a distributed energy management task allocation strategy for a multi-robot system (MRS) involved in goods transportation. The main goal in such type of application is maximizing the productivity by transporting the maximum of goods. However, an important aspect of the optimal use of an MRS is an efficient energy management. The aim of this work is to develop a distributed cooperative strategy that considers energy management in task allocation. For this purpose, an Iterative Local Search-based (ILS) metaheuristic and a novel heuristic-based utility function are developed to solve the multi-robot task allocation problem. The proposed strategy uses the MRS as a population of individuals to solve the task allocation in a parallel distributed manner. Each robot runs the ILS-based algorithm and provides its solution for the task allocation, due to the fact that some of ILS parameters are randomly chosen. Thus, this strategy combines the exploration advantage of the population-based metaheuristics and the exploitation advantage and easy implementation on embedded systems (e.g., MRS) of the single-point-search metaheuristics. The proposed strategy is evaluated in a simulated environment and compared to three heuristics, in terms of the average consumed energy, the productivity of the system, and productivity per energy unit consumed.
Lifetime and Predissociation Yield of 14 N 2 b 1 u (v=1)

The lifetime of the b (1)Pi(u)(v=1) state in N-14(2) has been determined experimentally using a laser-based pump-probe scheme and an exceptionally long lifetime of 2.61 ns was found. Semiempirical close-coupling calculations of the radiative lifetime, which include Rydberg-valence interactions in the singlet manifold, are consistent with this large value, giving a value of 3.61 ns and suggesting a predissociation yield of similar to28% for this level of the b state.

Bis (Diamines) Cu and Zn Complexes of Flurbiprofen as Potential Cholinesterase Inhibitors: In Vitro Studies and Docking Simulations

Alzheimer’s disease (AD) causes dementia and continuous damage to brain cells. Cholinesterase inhibitors can alleviate the condition by increasing communication between the nerve cells and reducing the risk of dementia. In an effort to treat Alzheimer’s disease, we synthesized flurbiprofen-based diamines (1,2 diaminoethane and 1,3 diaminopropane) Zn(II), Cu(II) metal complexes and characterized them by single-crystal X-ray analysis, NMR, (FT)-IR, UV-Vis, magnetic susceptibility, elemental analysis and conductivities measurements. Synthesized diamine metal complexes appeared in ionic forms and have distorted octahedral geometry based on conductivity studies, magnetic susceptibility and electronic studies. Single crystal X-ray diffraction analysis confirmed (2b) Cu(H2O)2(L1)2(L2)2 complex formation. Moreover, we tested all synthesized metal complexes against the cholinesterase enzyme that showed higher inhibition potential. In general, copper metal complexes showed higher inhibitory activities than simple metal complexes with flurbiprofen. These synthesized metal complexes may derive more effective and safe inhibitors for cholinesterases.
Validation of the Axial Thrust Estimation Method for Radial Turbomachines

The fast preliminary design and safe operation of turbomachines require a simple and accurate prediction of axial thrust. An underestimation of these forces may result in undersized bearings that can easily overload and suffer damage. While large safety margins are used in bearing design to avoid overloading, this leads to costly oversizing. In this study, the accuracy of currently available axial thrust estimation methods is analyzed by comparing them to each other and to theoretical pressure distribution, numerical simulations, and new experimental data. Available methods tend to underestimate the maximum axial thrust and require data that are unavailable during the preliminary design of turbomachines. This paper presents a new, simple axial thrust estimation method that requires only a few preliminary design parameters as the input data and combines the advantages of previously published methods, resulting in a more accurate axial thrust estimation. The method is validated against previously public data from a radial pump and new experimental data from a centrifugal compressor, the latter measured at Lappeenranta-Lahti University of Technology LUT, Finland, and two gas turbines measured at Aurelia Turbines Oy, Finland. The maximum deviation between the estimated axial thrust using the hybrid method and the measured one is less than 13%, while the other methods deviate by tens of percent.
Low-Complexity High-Throughput QC-LDPC Decoder for 5G New Radio Wireless Communication

This paper presents a pipelined layered quasi-cyclic low-density parity-check (QC-LDPC) decoder architecture targeting low-complexity, high-throughput, and efficient use of hardware resources compliant with the specifications of 5G new radio (NR) wireless communication standard. First, a combined min-sum (CMS) decoding algorithm, which is a combination of the offset min-sum and the original min-sum algorithm, is proposed. Then, a low-complexity and high-throughput pipelined layered QC-LDPC decoder architecture for enhanced mobile broadband specifications in 5G NR wireless standards based on CMS algorithm with pipeline layered scheduling is presented. Enhanced versions of check node-based processor architectures are proposed to improve the complexity of the LDPC decoders. An efficient minimum-finder for the check node unit architecture that reduces the hardware required for the computation of the first two minima is introduced. Moreover, a low complexity a posteriori information update unit architecture, which only requires one adder array for their operations, is presented. The proposed architecture shows significant improvements in terms of area and throughput compared to other QC-LDPC decoder architectures available in the literature.
Estimation of Gourami Supplies Using Gradient Boosting Decision Tree Method of XGBoost

The need for food supplies are very crucial in a food business, therefore it is necessary to estimate the right supplies to maximize profit. One of the methods to determine these is by looking for patterns and forecasting transaction data. The purpose of this research is to estimate the gourami supplies using transaction data to forecast using the gradient boosting decision tree method from XGBoost. The transaction data used comes from Restaurant X with a time period from 2016 to 2019. A measurement error rate of the model is achieved by using MAE (Mean Absolute Error) and MAPE (Mean Absolute Percentage Error). This study tried five XGBoost models with different features such as lag, rolling window, mean encoding, and mix. The results of this study indicate that the mixed feature model produces an accuracy of 97.54% with an MAE of 0.63 and a MAPE of 2.64%.

Physical, Optical, and Visual Performance of Coated Cross-Laminated Timber during Natural and Artificial Weathering

Cross-laminated timber (CLT) market demand is on the rise in the United States. Adequate protective measures have not been extensively studied. The objective of this study was to investigate the weathering performance of exterior wood coatings. We evaluated coated CLT sample surfaces based on visual appearance, color change (CIE*L*a*b), gloss changes, and water intrusion. From the five exterior wood coatings evaluated, only two showed adequate performance after twelve months field exposure. Based on visual ratings following the ASTM procedures, coating failure occurs more quickly in Mississippi than in Wisconsin, due to its greater decay zone. Both location and coating type impacted the aging of the samples. Artificial weathering results were consistent with natural weathering indicating the two adequate coatings were the most resistant to failure, color, and gloss change. For future studies, new coatings designed for the protection of end-grain in CLT panels should be a target of research and development.
Not All Physical Performance Tests Are Related to Early Season Match Running Performance in Professional Rugby League

Supplemental Digital Content is Available in the Text. Abstract Glassbrook, DJ, Fuller, JT, Wade, JA, and Doyle, TLA. Not all physical performance tests are related to early season match running performance in professional rugby league. J Strength Cond Res 36(7): 1944–1950, 2022—This study aimed to determine which physical tests correlate with early season running performance. Sixteen professional rugby league players performed the 30-15 intermittent fitness test (IFT), 1.2-km time trial, 1 repetition maximum (RM) barbell back squat, isometric midthigh pull (IMTP), countermovement jump (CMJ), barbell squat jump (SJ), and ballistic bench press throw (BBP). Bivariate Pearson's correlations and linear regression were used to compare physical tests with peak match running intensities recorded by a portable Global Positioning System and represented by peak match velocity and acceleration, as well as peak 1-, 4-, 6-, and 8-minute instantaneous acceleration/deceleration periods of play. Significant (p < 0.05) negative correlations (r = −0.55 to −0.60) were observed between the IFT and relative 1-, 4-, 6-, and 8-minute peaks, and between the relative 1RM back squat and relative 1-, 4-, 6-, and 8-minute peaks. Significant positive correlations (r = 0.52–0.84) were observed between the following physical tests and match performance pairs: IFT and peak acceleration; relative 1RM back squat and peak acceleration; SJ peak power (relative and absolute) and peak acceleration; CMJ peak force (relative and absolute) and peak acceleration; CMJ peak power (relative and absolute) and peak acceleration and 1-, 4-, 6-, and 8-minute peaks; and relative BBP peak power and peak velocity and peak acceleration. The results of this study highlight that not all generic tests of physical qualities are related to peak match running performance and only those with significant correlations are likely to be able to indicate how players may perform during match-play.
Can central bank communication help to stabilise inflation expectations?

This paper examines whether central bank communication stabilises euro area inflation expectations through the information and news channel. A novelty of the study is its use of data from Google Analytics on ECB website traffic as proxy for visitors’ attention to its communication. We conduct several econometric tests with daily data to measure the impact of ECB communication on the information demand of the public and ultimately on inflation expectations. Overall, this study shows that website attention, as captured by search volumes of visitors, influences euro area inflation expectations. We find that increased website attention contributes to narrowing the gap between market-based forecasts and (the mean of) longer-term professional inflation expectations. Our findings add to the theoretical evidence on the existence of an information and news channel. JEL Codes : C20
Superconductivity at 1 K in Y-Au-Si quasicrystal approximants

We report the structural and physical properties of two Y-Au-Si (YAS) compounds, ${\mathrm{Y}}_{14.1}{\mathrm{Au}}_{69.2}{\mathrm{Si}}_{16.7}$ and ${\mathrm{Y}}_{15.4}{\mathrm{Au}}_{68.6}{\mathrm{Si}}_{16.1}$, which are 1/1 approximant crystals of a Tsai-type quasicrystal without intrinsic magnetic moments. The compounds differ by the presence of either a tetrahedron (Au,Si)${}_{4}$ or a single Y atom at the center of their characteristic structural building unit consisting of concentric polyhedral shells. Both compounds exhibit bulk superconductivity, which seems to be of a conventional type-II BCS type. The compound with Y atoms at the cluster center has a slightly higher transition temperature with a sharper step in the specific heat than the compound with tetrahedral units. We discuss the occurrence of this superconducting state in the light of the specific structural and physical properties of these quasicrystal approximants.
Tennis‐resource allocation mechanism in software‐defined data center network

With the rapid development of cloud computing, most network resources are usually stored at Data Center Network (DCN) for providing the remote storage services. Under such paradigm, there arises some issues, such as traffic scheduling, energy saving and resource allocation. At present, the resource allocation in DCN has attracted the extensive concern. In order to effectively manage and allocate these resources in DCN, Software‐Defined Networking can be employed to achieve such purpose, by leveraging its natural abilities for the global control and centralized management. Another point, the tennis is a very popular sport to enhance the physical fitness. However, the tennis‐resources are considerably limited as the building of venue is quite expensive. Therefore, it becomes very significant to investigate the tennis‐resource allocation in Software‐Defined DCN (SDCN). Consider that there are many tenants using the tennis‐resources in SDCN, this paper studies the multi‐tenant tennis‐resource allocation scenario. Meanwhile, the Global Superiority Equalization algorithm is devised. At first, the max‐min fairness is used to determine the allocated number of tennis‐resources for each round. Then, the allocation state is adjusted according to the current situation until the final allocation decision is determined. The experiment results show that the proposed tennis‐resource allocation mechanism can reduce the resource allocation cost and improve the resource utilization. Accordingly, SDCN can handle more tennis‐resource requests and increase the benefit of venue provider.
Design of compact broadband dual‐polarized antenna for 5G applications

This article presents a compact broadband dual‐polarized antenna for use in the sub‐6 GHz 5G applications. The antenna is a novel magneto‐electric (ME) dipole with microstrip‐line aperture‐coupled feed, that is, it is composed of two orthogonal microstrip‐lines coupled with four shorted patches through a crossed slot for the broadband dual‐polarized radiation. The electric and magnetic dipole modes are formed by the shorted patches and the gap between the patches, respectively. Therefore, the antenna achieves a low‐profile. To reduce the back radiation at the aperture‐coupled feed and remain the low‐profile, the antenna is backed by a high impedance surface. The final design with an overall size of 50 mm × 50 mm × 12.5 mm (0.5λmin × 0.5λmin × 0.125λmin) has been fabricated and measured. The measurements result in a bandwidth of 33% (3.02‐4.02 GHz) for voltage standing wave ratio <1.5 and an isolation of >25 dB among the two ports. Its bandwidth covers the specific 5G NR n78 band (3.3‐3.8 GHz). In addition, the antenna achieved a broadside gain of 7.9‐8.5 dBi, a front‐to‐back ratio of >18 dB, and a cross‐polarization level of <− 20 dB across the operational bandwidth.
Numerical Simulation, Response Analysis, and Physical Experiment of Induction Logging in an Inclined Fractured Formation

The majority of previous studies of induction logging in fractured formations have typically focused on the variation in spatial resistivity distribution around the wellbore. However, the effect of cumulative charge on the boundaries of an inclined fracture with a distinct morphology on induction logging has rarely been discussed. In this work, the 3-D finite element method (3-D FEM) is adopted to investigate the dual-induction logging response of inclined fractures in formations of different resistivities considering the volume contribution and charge contribution. First, induction logging theory is studied, and a 3-D fractured formation model considering cumulative charges is established. Second, the induction logging responses under various fracture resistivities, apertures, dip angles, and formation resistivities are simulated and analyzed. Subsequently, the corresponding logging response characteristics are studied, and the different response laws of inclined fractures in high- and low-resistivity formations are systematically summarized. Third, a 1:5 miniaturized dual-induction logging instrument was designed and manufactured. Furthermore, two devices were built to measure the induction logging response of the inclined fracture (simulated by nanoscale silver film or metal wire mesh) in low- and high-resistivity formations. The results of the physical experiments are consistent with the numerical results, validating the accuracy of the numerical simulation. Both the results reveal that due to the existence of cumulative charge layers on the upper and lower inclined fracture boundaries, the induction logging response rules of the conductive fractures in high-resistivity formations differ from those in low-resistivity formations, and hence, they should be treated differently.
Physical functional capacity of patients with glioma prior to adjuvant radiation: preliminary descriptive study.

Background Few studies have assessed physical functioning in glioma patients with grade II, III, and IV glioma prior to undergoing adjuvant radiation with or without chemotherapy. The aim of this study was to describe the baseline physical functioning capacity of patients with glioma prior to adjuvant therapy compared to validated cutoffs required to maintain independence. Methods This study is a cross-sectional study that recruited patients with grade II, III, and IV glioma (n = 33) undergoing adjuvant radiation with or without chemotherapy. The six-minute walk, thirty-second sit-to-stand, and timed "Up & Go" assessments were used to describe baseline physical functioning. Perceived quality of life from the European Organisation for Research and Treatment of Cancer (EORTC) quality of life questionnaire (QLQ-C30) version 3.0 was used to quantify the quality of life. Results Mean distance walked in the six-minute walk test was 416.2 m (SD 137.6 m) with a mean of 12.2 stands (SD 3.4 stands) achieved during the thirty-second sit-to-stand. Median time to complete the timed "Up & Go" assessment was 7 s (interquartile range: 3 s). One-sample t tests suggest walking distance and chair stands were significantly lower than cutoff criterions to maintain independent living, t(32) = -5.96, P < . 001, bias-corrected accelerated 95% CI [370.7-460.4], and t(32) = -4.60, P < . 01, bias-corrected accelerated 95% CI [11.0-13.4], respectively. Wilcoxon signed-rank test identified significantly shorter median time taken to complete the timed "Up & Go" test compared to the cutoff criterion (z = -4.43, n = 33, P < .01). Conclusion This study suggests glioma patient's aerobic endurance and lower limb strength are below criterion cutoffs recommended to maintain independent living. Timed "Up & Go" scores did not exceed the criterion cutoff, indicating respectable levels of mobility.
A Di-Carbazole-Based Dye as a Potential Sensitizer for Greenhouse-Integrated Dye-Sensitized Solar Cells

For the first time in dye-sensitized solar cell (DSSC) technology, a di-carbazole-based dye was synthesized and evaluated for its usage as a potential sensitizer for the development of wavelength selective semi-transparent DSSCs for greenhouses-oriented applications. The dye was designed to demonstrate a blue light absorption, allowing a high transmittance in the red region of the visible light, even after its adsorption on the anode semiconductor, which is the most important one for the photosynthetic action of the plants. The application of the new dye to DSSCs was examined using either a high-performance iodide-based electrolyte or a highly transparent iodine-free electrolyte to determine a good balance between electric power generation and device transparency. The spectral engineered DSSCs demonstrated quite promising characteristics, providing a high external quantum efficiency (higher than 70%) in the whole blue–green region of the visible light, while allowing high transparency (up to 55%) in the red region, where the second peak in the absorbance spectrum of chlorophyll is located. Finally, the derived results were discussed under the consideration of important metrics for this niche application, including the transparency of the solar cells in the region of photosynthetic active radiation and the attained crop growth factor. The present work constitutes one of the few comprehensive studies carried out up to now in the direction of the development of 3rd generation “agrivoltaics” for their possible integration as cladding materials in energy-autonomous greenhouses.
