Published: September 2024

This paper investigates the impact of higher derivative input shaping for minimizing both oscillations, namely hook and payload of a multimode double-pendulum overhead crane (MDPOC) system. The MDPOC has greater nonlinearities and stronger internal couplings, especially when involving two oscillation frequencies with multimode dynamic effects. With a suitable system’s natural frequency and damping ratio of the hook and payload oscillations, multimode zero-vibration (ZV-ZV), multimode zero-vibration derivative (ZVD-ZVD) and multimode zero-vibration derivative-derivative (ZVDD-ZVDD) shapers are successfully designed. More interestingly, two scenarios under a fixed cable length and a payload hoisting are considered which are closer to the real practical crane. Thus, an average travel length (ATL)-based shaper method is also considered to further verify the effectiveness and robustness of efficient hook and payload oscillation control under payload hoisting. All the multimode input shaping is simulated using the Matlab software. The simulation results of multimode ZVDD-ZVDD shaper successfully reduced in the overall hook and payload oscillations by 97.9% and 97.2%, respectively, compared to the unshaped system, whereas the multimode ATL-ZVDD shaper reduced hook and payload oscillations by 94.8% and 94.0%, respectively. In fact, the multimode ZVDD-ZVDD and multimode ATL-ZVDD shapers demonstrate the superiority in minimizing the hook and payload oscillations compared to the multimode ZV-ZV, multimode ZVD-ZVD, ATL-ZV and ATL-ZVD shapers. This significant reduction in oscillations enhances the precision and safety of real-world crane operations in industrial settings. It has been proven that considering the additional derivative of input shaping results in a higher level of hook and payload oscillations reduction.

The black locust (Robinia pseudoacacia) population vital state in the urban ecosystem
Authors: Kunakh O. 
Published: September 2024

Many European countries have extensively practiced the cultivation of black locust. This species is characterised by rapid growth, the application possibility for degraded land reclamation and other useful properties, but its adventiveness and invasive status require more thorough research. The aim of the research was to assess the viability of a population of black locust (Robinia pseudoacacia) in urban environment by determining its vital status and measuring height of the plants and diameter of their trunks as the main morphometric indicators. The research was conducted in the recreational area of the Oles Honchar Dnipro National University Botanical Garden. There were recorded 178 plants of R. pseudoacacia. Tree heights were measured by a Suunto PM-5 mechanical height meter in three-time repetition for each plant, and the average value was calculated based on these data. The trunk diameter was measured at the small fork as a distance between two parallel tangents. The vital status of the trees was determined by the 5-point scale of V. A. Alekseev. The height of the vast majority of the studied trees varied 25 to 30 m. The height of one species representative reached 32 m. The trunk diameter of the most trees in the territory ranged 30 to 40 cm. Plants with a trunk diameter of between 40 cm and 50 cm were the next largest group. A 101 cm trunk diameter was found in just one tree. Most plants in the research area had a vitality score of 2 – good state. Accordingly, these were the plants that had the largest trunks of examined trees. The fewest number of plants was in a very bad state and had a score of 5. The good and satisfactory vital conditions were observed in plants whose trunks were the tallest and had the largest diameter, and whose morphometric indices slightly varied (the height-diameter trunk correlation was reliable). Plants in depressed and poor vital state were characterised by significant variability in the morphometric parameters (the correlation between height and trunk diameter was not reliable). The ecological condition of the black locust population in the area was assessed, and it was concluded that its morphometric parameters cannot be used as indicators of plant vitality.

IntroductionAbnormal placentation contributes to obstetric morbidity in antiphospholipid antibodies syndrome (APS). The placenta is the main target of antiphospholipid antibodies (aPL) in obstetric APS and is the site of dysfunctional inflammatory responses and thrombosis. Standard treatment for APS during pregnancy includes low-dose aspirin (LDA) plus low molecular weight heparin (LMWH) and, in refractory cases, hydroxychloroquine (HCQ). Recently, a systematic review of the literature identified five main pathological placental lesions in APS patients: placental infarction, decidual vasculopathy, decidual inflammation, increase of syncytial knots due to syncytiotrophoblast death, and decrease in vasculosyncytial membranes. The aims of this study were to investigate whether placental lesions associate with obstetrical outcomes in a cohort of APS patients.Methods130 pregnant APS patients evaluated between 2009 and 2023 at the High-Risk Obstetrics Outpatient Clinic of San Raffaele Hospital, Milan, were enrolled. Placental samples from 25 spontaneously conceived pregnancies in APS patients were collected from January 2017 to May 2023 and analyzed.ResultsAll (n = 130) patients were on LDA and 110/130 (85%) on both LDA and LMWH. Twenty-six patients (20%) also received HCQ. In these patients, signs of placental inflammation (preterm birth and preterm premature rupture of membranes) were less frequently observed. Of the 25 placental samples analyzed, 19 (76%) patients had primary APS, while 6 patients had APS secondary to SLE. All patients were treated with LDA and LMWH. In patients with concomitant systemic lupus erythematosus (SLE) or in refractory APS, HCQ was added. Histological analysis of placental tissue revealed increased syncytial knots in 17/25 (68%) placentas, decreased vasculosyncytial membranes in 11/25 (44%), infarction in 8/25 (32%), presence of macrophages and decidual inflammation in 2/25 (8%), and atherosis or reduction of spiral artery remodeling in 3/25 (12%). We also observed at least two coexisting placental lesions in 12/25 (48%) placentas. In the placenta of patients treated with HCQ we did not observe any decidual inflammation at histology.ConclusionPlacental anomalies have occurred in patients with APS despite close and optimal obstetric monitoring. It is thus tempting to speculate that HCQ may have beneficial effects on pregnancy by decreasing the risk of deciduitis in patients with APS.

The Debt Dilemma: Driver or Brake of Innovation in the EU?
Authors: Fisera Tomas , Vanicek Bernard 
Published: September 2024

In the current economic environment, the issue of increasing indebtedness is receiving considerable attention. This article delves deeper into a comprehensive analysis of how different forms of debt – from households to corporations to governments – affect innovation performance within the European Union (EU). Since the EU includes 25 different countries, it provides a rich background for this analysis covering the period from 2013 to 2021. By applying regression analysis techniques on a large dataset, this study offers a new insight into the complex relationship between indebtedness and innovation performance. A key part of this analysis is the Global Innovation Index, widely recognized as a metric for evaluating innovation performance among nations. The empirical findings of this study reveal a subtle dynamic: while government debt appears to be a drag on innovation performance, private sector indebtedness, including both households and non-financial institutions, shows a positive effect. This dichotomy underlines the crucial importance of implementing responsible fiscal policies that prioritize the promotion of innovation without jeopardizing financial stability. In addition, the research highlights the importance of fostering collaboration between the public and private sectors, supporting university research, and developing innovation incubators to create a robust innovation environment. In addition, this study not only clarifies the current status, but also identifies areas requiring further research, such as research into other factors influencing the innovation environment. However, it is important to acknowledge the limitations associated with the current understanding of the relationship between debt and innovation. These limitations underscore the need for continued refinement of methodologies and investigation of other factors that may influence this interaction, thereby providing fertile ground for future research efforts. In conclusion, this study contributes to a deeper understanding of how debt dynamics shape innovation outcomes in the EU context.

Published: September 2024

Higher Education Institutions (HEIs) have been mandated with the task to train and produce graduates with the capability to contribute to the economy and improve societies through teaching and learning. Furthermore, they are tasked with the responsibility to produce graduates with the capability to produce innovations that change the world for the better. For a university to produce such graduates it would need to focus on the curriculum and ensure that the skills and knowledge taught are relevant to produce innovative graduates. The purpose of this research paper was to identify the predicted and prized skills that a graduate can use to produce groundbreaking innovations. This objective would yield guidance on the most critical skills that should be included in a BCom degree to produce graduates with the capability to produce groundbreaking innovations. This research employed a Mixed-method approach with the use of both qualitative and quantitative approach. Data was collected using semi-structured interviews with 11 participants from the University of Johannesburg commercialisation units and an online questionnaire from 69 innovation experts from the South African Business Innovation Community (Innovation Summit), and the Innovation, Sustainability and Visionary Leadership Group. Data was collected through descriptive content analysis with the aid of Atlas.ti and inferential statistical analysis. This study is part of a completed PhD study, the reporting is only on Predicted and Prized critical skills for a BCom degree graduate. Based on the results ideation, reasoning, problem solving, complex problem solving, critical thinking, creativity and analytical thinking are skills and competences predicted to improve innovation and produce graduates with the capability to innovate. Furthermore, based on the results critical thinking, judgement and decision making are very significant skills for a person with a BCom degree. In conclusion, HEIs should place more emphasis on critical thinking skills within the curriculum and complex problem-solving skills. These skills should not only be exclusive to certain programmes but throughout the entire HEI’s curriculum.

Uncollected solid waste has become an ever-growing threat to our livelihoods, posing many problems that span health risks, environmental pollution, and unpleasant aesthetics. Traditional methods of reporting uncollected solid waste have proven ineffective and we struggle to keep pace in addressing the growing volumes of waste. This study focused on developing a solid waste detection and reporting system based on machine learning and geotagging. The developed system sought to enable solid waste management entities to obtain verified solid waste reports and accurate location details of the uncollected waste instances. A ResNet model was trained on commonly used solid waste image datasets from online sources. The model achieved a provisional accuracy beforescore of seventy percent (70%) though this statistic can be improved by adjusting model parameters. A rapid iterative design approach was employed to facilitate the development of the crowdsourcing app. This enabled the researchers to swiftly build, evaluate, and refine functional prototypes of the system before finalization. The resulting system receives solid waste images together with their location data and verifies the correct image reports using the trained model, before finally visualizing the reports on a map. Overall, the system provides a platform for the general public to collaborate with solid waste management bodies in combatting uncollected solid waste. In the future, the system may be diversified to allow reporting other amenity issues besides uncollected solid waste.

Recent trends in Lisbon's winter tourism indicate a shift towards off-peak travel, attracting diverse visitors with its rich cultural heritage, sustainable initiatives, and extended stay options for digital nomads. The city's culinary scene, arts, wellness activities, and tech-driven tourism options enhance its appeal. Aligned with these recent trends, tourism in Lisbon's region during the winter season presents a unique and dynamic landscape influenced by a wide range of motivations, tourist profiles, and travel behaviours. This study aims to define distinctive clusters of winter tourists in Lisbon by analysing these key variables, providing valuable insights specific to the winter travel context. Based on a compiled dataset from the winter season in Lisbon, this study delves into examining the factors driving tourist visits, encompassing socio-economic backgrounds, travel frequency, and age demographics. We aim to reveal the distinctive subgroups that define Lisbon's winter tourist population, employing data analysis techniques such as cluster analysis. From an academic perspective, this study offers a novel tourist segmentation model based on motivations, profiles, and behaviour. This model enriches the existing body of knowledge in tourism studies, providing a valuable reference for future research. For tourism agents in Lisbon, this study provides actionable insights to enhance strategic decision-making. By segmenting winter tourists, they can tailor marketing strategies and product development to cater to diverse tourist segments. Moreover, this approach can lead to economic benefits, optimising resource allocation, and revenue generation.
Perceived Success and Entrepreneurial Identity in West Africa
Authors: Hajji Nouha 
Published: September 2024

This research aims to understand the Fake It Until You Make It (FIUYMI) culture and its impact on entrepreneurial identity in the West African startup ecosystem. Self-presentation is important for entrepreneurs and often they tend to exaggerate their success. In West Africa, this is usually the case for entrepreneurs that want to gain social acceptance among their peers and to secure funding. It is represented by a desire of belonging and is amplified with digital social platforms and peer pressure. This study aims to evaluate the impact of perceived success using mixed methods research with both qualitative and quantitative data. The qualitative phase consists of semi-structured interviews with 20 startup founders from West Africa. The initial objective is to understand the motivations behind employing FIUYMI behaviour and its effect on the entrepreneurial identity and sense of success. A structured survey is then conveyed to 50 startup founders across the same region. The second objective is to quantitatively assess the prevalence of this behaviour and its impact on self-perception, and psychological well-being. Results suggest that FIUYMI is at first a good strategy for entrepreneurs to enhance perceived credibility and attract support and can be a positive tool for entrepreneurs to some extent as it boosts their confidence and network. It may later lead to psychological stress and has a perverse effect on entrepreneurs of not belonging to their community: Even when they achieve their desired outcome, they may consider their achievements to be fraudulent which is linked to a sense of imposter phenomenon. The research goal is to understand the complexities of perceived success and the ‘Fake it Until You Make it’ attitude in the West African context informing effective interventions in entrepreneurial behaviour. By showing its negative impact on an entrepreneur's journey, the research also aims to enhance accurate self-presentation and contribute to a more trustworthy entrepreneurial ecosystem in West Africa for entrepreneurs and investors.
