Optimum structural design with static aeroelastic constraints

The static aeroelastic performance characteristics, divergence velocity, control effectiveness and lift effectiveness are considered in obtaining an optimum weight structure. A typical swept wing structure is used with upper and lower skins, spar and rib thicknesses, and spar cap and vertical post cross-sectional areas as the design parameters. Incompressible aerodynamic strip theory is used to derive the constraint formulations, and aerodynamic load matrices. A Sequential Unconstrained Minimization Technique (SUMT) algorithm is used to optimize the wing structure to meet the desired performance constraints

Adoption of social media marketing for sustainable business growth of SMEs in emerging economies: The moderating role of leadership support

Social media marketing (SMM) plays an important role in business communication, mar-keting, operations, and other activities. There is a growing interest among researchers, academicians, and practitioners to understand the role of SMM in business sustainability in small and medium enterprises (SMEs) in an emerging economy, like India. Few studies have attempted to understand this role. Thus, the aim of this study is to examine the impact of adopting social media marketing for sustainable business growth of SMEs in an emerging economy. The study also investigates the moderating role of SME leadership support on the relationship between SMM usage and sustainable business growth of SMEs. After reviewing the existing literature and technology adoption model, a theoretical model is developed, which is then validated using a structural equation modeling tech-nique to analyze 304 samples of Indian SMEs that use different social media marketing applications in their enterprises. This study confirmed that SMM tools significantly and positively improve the sustainable growth of SMEs in an emerging economy. Additionally, the study also found that SME leadership team plays a vital role in supporting actual usage of SMM tools that accelerate sustainable business growth of SMEs

Performance Improved Active Power Filter Using Fuzzy Based Adaptive Controller for Renewable Power Generation Systems

An Active power filter implemented with a four-leg voltage-source inverter utilizing a predictive control scheme is introduced. The utilization of a four-leg voltage-source inverter permits the pay of current consonant parts, and in addition lopsided current created by single-stage nonlinear burdens. A point by point yet straightforward numerical model of the dynamic power channel, including the impact of the identical power framework impedance, is determined and used to plan the prescient control calculation. The pay execution of the proposed dynamic power channel and the related control plan under enduring state and transient working conditions is shown through reproductions results. As of late, fuzzy logic controller was connected for active power filter (APF) control application, as the APF is only a current controlled VSI. In this paper, a fuzzy logic based shunt APF is displayed in light of the compelling time idea. The viable time idea disposes of the trigonometric counts and part ID, along these lines it lessens the computational exertion. Reenactment results show the viability of the APF with the fuzzy logic based control procedure. Reproduction results are acquired for both PI controller and fuzzy logic controller and the outcomes are thought about. In the fuzzy controlled four leg inverter APF is utilized for power quality change

Association of Noncontrast Computed Tomography and Perfusion Modalities With Outcomes in Patients Undergoing Late-Window Stroke Thrombectomy

Importance: There is substantial controversy with regards to the adequacy and use of noncontrast head computed tomography (NCCT) for late-window acute ischemic stroke in selecting candidates for mechanical thrombectomy. Objective: To assess clinical outcomes of patients with acute ischemic stroke presenting in the late window who underwent mechanical thrombectomy stratified by NCCT admission in comparison with selection by CT perfusion (CTP) and diffusion-weighted imaging (DWI). Design, setting, and participants: In this multicenter retrospective cohort study, prospectively maintained Stroke Thrombectomy and Aneurysm (STAR) database was used by selecting patients within the late window of acute ischemic stroke and emergent large vessel occlusion from 2013 to 2021. Patients were selected by NCCT, CTP, and DWI. Admission Alberta Stroke Program Early CT Score (ASPECTS) as well as confounding variables were adjusted. Follow-up duration was 90 days. Data were analyzed from November 2021 to March 2022. Exposures: Selection by NCCT, CTP, or DWI. Main outcomes and measures: Primary outcome was functional independence (modified Rankin scale 0-2) at 90 days. Results: Among 3356 patients, 733 underwent late-window mechanical thrombectomy. The median (IQR) age was 69 (58-80) years, 392 (53.5%) were female, and 449 (65.1%) were White. A total of 419 were selected with NCCT, 280 with CTP, and 34 with DWI. Mean (IQR) admission ASPECTS were comparable among groups (NCCT, 8 [7-9]; CTP, 8 [7-9]; DWI 8, [7-9]; P = .37). There was no difference in the 90-day rate of functional independence (aOR, 1.00; 95% CI, 0.59-1.71; P = .99) after adjusting for confounders. Symptomatic intracerebral hemorrhage (NCCT, 34 [8.6%]; CTP, 37 [13.5%]; DWI, 3 [9.1%]; P = .12) and mortality (NCCT, 78 [27.4%]; CTP, 38 [21.1%]; DWI, 7 [29.2%]; P = .29) were similar among groups. Conclusions and relevance: In this cohort study, comparable outcomes were observed in patients in the late window irrespective of neuroimaging selection criteria. Admission NCCT scan may triage emergent large vessel occlusion in the late window

Vampires in the village Žrnovo on the island of Korčula: following an archival document from the 18th century

Središnja tema rada usmjerena je na raščlambu spisa pohranjenog u Državnom arhivu u Mlecima (fond: Capi del Consiglio de’ Dieci: Lettere di Rettori e di altre cariche) koji se odnosi na događaj iz 1748. godine u korčulanskom selu Žrnovo, kada su mještani – vjerujući da su se pojavili vampiri – oskvrnuli nekoliko mjesnih grobova. U radu se podrobno iznose osnovni podaci iz spisa te rečeni događaj analizira u širem društvenom kontekstu i prate se lokalna vjerovanja.The main interest of this essay is the analysis of the document from the State Archive in Venice (file: Capi del Consiglio de’ Dieci: Lettere di Rettori e di altre cariche) which is connected with the episode from 1748 when the inhabitants of the village Žrnove on the island of Korčula in Croatia opened tombs on the local cemetery in the fear of the vampires treating. This essay try to show some social circumstances connected with this event as well as a local vernacular tradition concerning superstitions

Millennial generation preferences for rosé wine: An exploratory study of the Italian and French markets

Purpose: The purpose of this paper is to verify the preferences for the purchase of rosé wine by Italian and French Millennials, with the aim of allowing Italian companies to acquire knowledge in improving the positioning of this product in both the Italian and French markets. Design/methodology/approach: The study involved a descriptive survey conducted between December 2018 and January 2019 on Millennials residing in Italy and France, intercepted via Facebook. In total, 500 valid responses to a highly structured self-administered questionnaire were collected. Descriptive and multivariate analysis techniques were used to examine the responses. Findings: The two groups of Millennials show different preferences in the purchase of rosé wine. French Millennials rarely buy the product, and perhaps only for reasonable prices. Their purchasing process involves no characteristics of particular importance. On the other hand, Italian Millennials buy the product with a higher frequency and show a greater propensity to spend. In general, they attribute greater importance (though not a great deal of importance) to the characteristics of the product, paying attention to both its intrinsic aspects and its territorial origin and the quality certifications. Research limitations/implications: The main limitation of the research is the small sample size. Future insights into the consumption of rosé wine will be sought in other significant European markets. Practical implications: This study is of value to academic researchers, wine industry practitioners and other members of the wine distribution channel, as it provides insights into consumer behavior differences. Originality/value: This research is the first to compare rosé wine preferences of Millennials in France and Italy
