Authors: Dessimond Boris , Annesi-Maesano Isabella , Pepin Jean-Louis , Srairi Salim , Pau Giovanni
Published: March 2021

The World Health Organization has estimated that air pollution is a major threat to health, causing approximately nine million premature deaths every year. Each individual has, over their lifetime, a unique exposure to air pollution through their habits, working and living conditions. Medical research requires dedicated tools to assess and understand individual exposure to air pollution in view of investigating its health effects. This paper presents portable sensors produced by the Canarin Project that provides accessible, real time personal exposure data to particulate matter. Our primary results demonstrate the use of portable sensors for the assessment of personal exposure to the different micro-environments attended by individuals, and for inspecting the short-term effects of air pollution through the example of sleep apnea. These findings underscore the necessity of obtaining contextual data in determining environmental exposure and give perspectives for the future of air pollution sensors dedicated to medical research.

Published: March 2021

A quality monitoring system for telecommunication services is relevant for network operators because it can help to improve users’ quality-of-experience (QoE). In this context, this article proposes a quality monitoring system, named Q-Meter, whose main objective is to improve subscriber complaint detection about telecommunication services using online-social-networks (OSNs). The complaint is detected by sentiment analysis performed by a deep learning algorithm, and the subscriber’s geographical location is extracted to evaluate the signal strength. The regions in which users posted a complaint in OSN are analyzed using a freeware application, which uses the radio base station (RBS) information provided by an open database. Experimental results demonstrated that sentiment analysis based on a convolutional neural network (CNN) and a bidirectional long short-term memory (BLSTM)-recurrent neural network (RNN) with the soft-root-sign (SRS) activation function presented a precision of 97% for weak signal topic classification. Additionally, the results showed that 78.3% of the total number of complaints are related to weak coverage, and 92% of these regions were proved that have coverage problems considering a specific cellular operator. Moreover, a Q-Meter is low cost and easy to integrate into current and next-generation cellular networks, and it will be useful in sensing and monitoring tasks.
Multi-Temporal Change Detection Analysis of Vertical Sprawl over Limassol City Centre and Amathus Archaeological Site in Cyprus during 2015–2020 Using the Sentinel-1 Sensor and the Google Earth Engine Platform
Authors: Agapiou Athos
Published: March 2021

Urban sprawl can negatively impact the archaeological record of an area. In order to study the urbanisation process and its patterns, satellite images were used in the past to identify land-use changes and detect individual buildings and constructions. However, this approach involves the acquisition of high-resolution satellite images, the cost of which is increases according to the size of the area under study, as well as the time interval of the analysis. In this paper, we implemented a quick, automatic and low-cost exploration of large areas, for addressing this purpose, aiming to provide at a medium resolution of an overview of the landscape changes. This study focuses on using radar Sentinel-1 images to monitor and detect multi-temporal changes during the period 2015–2020 in Limassol, Cyprus. In addition, the big data cloud platform, Google Earth Engine, was used to process the data. Three different change detection methods were implemented in this platform as follow: (a) vertical transmit, vertical receive (VV) and vertical transmit, horizontal receive (VH) polarisations pseudo-colour composites; (b) the Rapid and Easy Change Detection in Radar Time-Series by Variation Coefficient (REACTIV) Google Earth Engine algorithm; and (c) a multi-temporal Wishart-based change detection algorithm. The overall findings are presented for the wider area of the Limassol city, with special focus on the archaeological site of “Amathus” and the city centre of Limassol. For validation purposes, satellite images from the multi-temporal archive from the Google Earth platform were used. The methods mentioned above were able to capture the urbanization process of the city that has been initiated during this period due to recent large construction projects.
A Novel Finger Vein Recognition Method Based on Aggregation of Radon-Like Features
Authors: Yao Qiong , Song Dan , Xu Xiang , Zou Kun
Published: March 2021

Finger vein (FV) biometrics is one of the most promising individual recognition traits, which has the capabilities of uniqueness, anti-forgery, and bio-assay, etc. However, due to the restricts of imaging environments, the acquired FV images are easily degraded to low-contrast, blur, as well as serious noise disturbance. Therefore, how to extract more efficient and robust features from these low-quality FV images, remains to be addressed. In this paper, a novel feature extraction method of FV images is presented, which combines curvature and radon-like features (RLF). First, an enhanced vein pattern image is obtained by calculating the mean curvature of each pixel in the original FV image. Then, a specific implementation of RLF is developed and performed on the previously obtained vein pattern image, which can effectively aggregate the dispersed spatial information around the vein structures, thus highlight vein patterns and suppress spurious non-boundary responses and noises. Finally, a smoother vein structure image is obtained for subsequent matching and verification. Compared with the existing curvature-based recognition methods, the proposed method can not only preserve the inherent vein patterns, but also eliminate most of the pseudo vein information, so as to restore more smoothing and genuine vein structure information. In order to assess the performance of our proposed RLF-based method, we conducted comprehensive experiments on three public FV databases and a self-built FV database (which contains 37,080 samples that derived from 1030 individuals). The experimental results denoted that RLF-based feature extraction method can obtain more complete and continuous vein patterns, as well as better recognition accuracy.

Published: March 2021

Current ultrasound techniques face several challenges to measure strains when translated from large tendon to in-situ knee collateral ligament applications, despite the potential to reduce knee arthroplasty failures attributed to ligament imbalance. Therefore, we developed, optimized and validated an ultrasound speckle tracking method to assess the in-situ strains of the medial and lateral collateral ligaments. Nine cadaveric legs with total knee implants were submitted to varus/valgus loading and divided into two groups: “optimization” and “validation”. Reference strains were measured using digital image correlation technique, while ultrasound data were processed with a custom-built speckle tracking approach. Using specimens from the “optimization” group, several tracking parameters were tuned towards an optimized tracking performance. The parameters were ranked according to three comparative measures between the ultrasound-based and reference strains: R2, mean absolute error and strains differences at 40 N. Specimens from the “validation” group, processed with the optimal parameters, showed good correlations, along with small mean absolute differences, with correlation values above 0.99 and 0.89 and differences below 0.57% and 0.27% for the lateral and medial collateral ligaments, respectively. This study showed that ultrasound speckle tracking could assess knee collateral ligaments strains in situ and has the potential to be translated to clinics for knee arthroplasty-related procedures.
Occupational Noise on Floating Storage and Offloading Vessels (FSO)
Authors: Rutkowski Grzegorz , Korzeb Jarosław
Published: March 2021

The purpose and scope of this paper are to provide guidance of the potential impacts of being subjected to high level noise recorded on 1st generation (30 years old) floating storage and offloading vessels (FSO) in sector offshore. The international community recognizes that vibroacoustic impacts from commercial ships may have negative consequences for both humans (worker’s) and marine life, especially marine mammals. As regards the effect of noise on human health, there are legal requirements imposing the noise exposure control on personnel working on ships. The acceptable noise exposure standards are established in European Union Directive 2003/10/EC (2003), the NOPSEMA Regulation (2006), the Maritime Labor Convention (MLC) guidelines (2006), and the recommendations of the International Maritime Organization IMO contained, e.g., IMO MEPC.1/Circ.833 (2014). These regulations inform employers and employees what they must do to effectively protect both the marine environment and the health and life safety of workers employed in the maritime industry offshore. This study also presents an analysis of the results of noise measurements carried out on exemplary 1st generation FSO units.
Light and Airy: A Simple Solution for Relativistic Quantum Acceleration Radiation
Authors: Good Michael R. R. , Linder Eric V.
Published: March 2021

We study the quantum radiation of particle production by vacuum from an ultra-relativistic moving mirror (dynamical Casimir effect) solution that allows (possibly for the first time) analytically calculable time evolution of particle creation and an Airy particle spectral distribution. The reality of the beta Bogoliubov coefficients is responsible for the simplicity, and the mirror is asymptotically inertial at the speed of light, with finite energy production. We also discuss general relations regarding negative energy flux, the transformation to the 1-D Schrödinger equation, and the incompleteness of entanglement entropy.
Piscine Orthoreovirus (PRV)-3, but Not PRV-2, Cross-Protects against PRV-1 and Heart and Skeletal Muscle Inflammation in Atlantic Salmon

Published: March 2021

Heart and skeletal muscle inflammation (HSMI), caused by infection with Piscine orthoreovirus-1 (PRV-1), is a common disease in farmed Atlantic salmon (Salmo salar). Both an inactivated whole virus vaccine and a DNA vaccine have previously been tested experimentally against HSMI and demonstrated to give partial but not full protection. To understand the mechanisms involved in protection against HSMI and evaluate the potential of live attenuated vaccine strategies, we set up a cross-protection experiment using PRV genotypes not associated with disease development in Atlantic salmon. The three known genotypes of PRV differ in their preference of salmonid host species. The main target species for PRV-1 is Atlantic salmon. Coho salmon (Oncorhynchus kisutch) is the target species for PRV-2, where the infection may induce erythrocytic inclusion body syndrome (EIBS). PRV-3 is associated with heart pathology and anemia in rainbow trout, but brown trout (S. trutta) is the likely natural main host species. Here, we tested if primary infection with PRV-2 or PRV-3 in Atlantic salmon could induce protection against secondary PRV-1 infection, in comparison with an adjuvanted, inactivated PRV-1 vaccine. Viral kinetics, production of cross-reactive antibodies, and protection against HSMI were studied. PRV-3, and to a low extent PRV-2, induced antibodies cross-reacting with the PRV-1 σ1 protein, whereas no specific antibodies were detected after vaccination with inactivated PRV-1. Ten weeks after immunization, the fish were challenged through cohabitation with PRV-1-infected shedder fish. A primary PRV-3 infection completely blocked PRV-1 infection, while PRV-2 only reduced PRV-1 infection levels and the severity of HSMI pathology in a few individuals. This study indicates that infection with non-pathogenic, replicating PRV could be a future strategy to protect farmed salmon from HSMI.

Published: March 2021

This report describes the first clinical case, to our knowledge, of a dog with polyglandular deficiency syndrome with diabetes mellitus and hypoadrenocorticism. A six-year-old female Cavalier King Charles Spaniel presented with a history of lethargy and appetite loss. The dog was diagnosed with diabetic ketoacidosis based on hyperglycemia and renal glucose and ketone body loss. The dog’s condition improved on intensive treatment of diabetes mellitus; daily subcutaneous insulin detemir injection maintained an appropriate blood glucose level over half a year. However, the dog’s body weight gradually decreased from day 207, and on day 501, it presented with a decreased appetite; the precise cause could not be determined. Based on mild hyponatremia and hyperkalemia, hypoadrenocorticism was suggested; the diagnosis was made using an adrenocorticotropic hormone stimulation test. Daily fludrocortisone with low-dose prednisolone oral administration resulted in poor recovery of the blood chemistry abnormalities; however, monthly desoxycorticosterone pivalate (DOCP) subcutaneous injection with daily low-dose prednisolone oral administration helped in the significant recovery of the abnormalities. Therefore, clinicians should consider the possibility of coexistence of hypoadrenocorticism in dogs with diabetes mellitus presenting with undifferentiated weight loss. Additionally, DOCP (not fludrocortisone) may be useful in treating dogs with diabetes mellitus complicated with hypoadrenocorticism.

Cardamomasos, Alvinich y Juandy son tres youtubers y vloggers bolivianos que cuentan con una gran audiencia en las redes sociales. Esto se debe a su capacidad para representar temáticas cotidianas por medio del humor. Sin embargo, los videos de estos tres creadores reproducen estereotipos y conceptos socioculturales relativos al “deber ser” de una mujer. Al mismo tiempo, generan la naturalización de los roles masculinos y femeninos por medio de su exhibición en las plataformas digitales (espacios de difusión que han adquirido mucha importancia en la actualidad). Por todo lo mencionado, el presente trabajo aborda la influencia de la representación estereotipada de las mujeres en los videos humorísticos de estos personajes.
Un acercamiento zoom a la comunicación en el 2020: Nuevos espacios (in) apropiados para comunicarse
Authors: Calvimontes Díaz Vanessa
Published: March 2021

El presente ensayo argumentativo propone una mirada crítica a las plataformas virtuales que se utilizan durante el periodo de distanciamiento social que se vive en Bolivia y el mundo a causa de la pandemia provocada por el coronavirus. Estas aplicaciones pasaron de ser escenarios eventuales de trabajo a convertirse en espacios de esparcimiento y encuentro social. Las limitaciones impuestas por el aislamiento, orillaron a los individuos a buscar nuevas formas de interacción; sin embargo, ¿estas alternativas cumplen con las premisas básicas para una comunicación asertiva? ¿Qué sucede cuando una reunión familiar se traslada a una pantalla de computadora y/o celular donde las limitaciones de expresión no verbal, los problemas tecnológicos, entre otros, están irremediablemente presentes? La comunicación enfrenta un nuevo dilema en el que la tecnología modifica la dinámica dialógica y, como consecuencia, afecta las relaciones socio-culturales. De este análisis surge la siguiente duda: ¿Estamos dispuestos a ceder y adaptarnos a esta nueva “normalidad?

Published: March 2021

Entrepreneurship drives every national or regional economy. Therefore, in fostering entrepreneurship need of a nation, researchers should focus on both the regional and local prospect of entrepreneurship. Although many scholars and policy makers devote their attention on the holistic entrepreneurial situation of a nation’s economy, it is equally important to predict the entrepreneurial determinants of various cultural groups. Therefore, the purpose of this paper is to determine the impacts of some factors on entrepreneurial intention of undergraduates of difference cultural groups in Nigeria. In this study, the theory of planned behaviour was used and the model was empirically tested on a sample of 200 higher institution students in Zamfara state. The finding shows that entrepreneurial intention is taken as a function of subjective norm and perceived behavioural control. Equally, the paper contributes to the literature by empirically comparing the entrepreneurial intention of Hausas and Igbos, it was discovered that Igbos are more entrepreneurial than the Hausas. The result of the study has valuable implications for the policy makers and educators. Since today’s youth are the potential entrepreneurs of the future, understanding their perception about entrepreneurship based on their cultural group can be a contribution to the development of the literature and an important step in designing a more effective policy mechanism for economic growth.

Contempt of Court behavior is rife in the process of resolving court disputes in Indonesia including civil disputes. Contempt of Court actions constitute an insult to the judiciary so that it is appropriate to be sanctioned as a deterrent eff ect. This study aims to determine the actions that can be qualified as a Contempt of Court in the settlement of civil disputes, as well as understanding the law enforcement of the Contempt of Court in the practice of dispute resolution in court and its comparison with Singapore. This study uses normative juridical methods. This method is carried out by examining library materials in the form of legislation, doctrine, and other scientific papers related to the Contempt of Court and interviews with sources to obtain primary data as a secondary data extras, which is then analyzed in a qualitative juridical analysis. The results of the research show that Civil Contempt actions in the practice of civil dispute resolution processes can be interpreted as any act done intentionally not in compliance with every summons, orders, decrees, warnings, or decisions issued by the court resulting in losses to parties who litigate and undermine the authority, dignity and honor of the court. Law enforcement against the actions of Civil Contempt of Court in Indonesia is still considered less eff ective when compared to Singapore. Singapore has included its arrangements in written rules governing the qualifi cations of actions and sanctions imposed. In addition to administrative and civil sanctions, criminal sanctions also apply in order to increase the effectiveness of enforcement of the Civil Contempt of Court.

Published: March 2021

The influence of water quality of Paniyala fish pond on its zooplankton composition and abundance were investigated at four stations for one year between January 2008 and December 2009. Diversity was not high: five groups of zooplankton were found which include Protozoa, Rotifera, Cladocera, Copepoda and Ostracoda. Rotifera dominated numerically (65.75±40.60 Unit/L), followed by protozoa (57.71±37.69 Unit/L) and Cladocera (47.31±28.73 Unit/L). The zooplankton was more prevalent during winter season and there were variations in the composition and abundance along the reservoir continuum. Factors such as temperature, nutrients, food availability, shape and hydrodynamics of the reservoir, as well as reproductive strategies of the organisms, strongly influence the composition and population density of zooplankton. Seasonal trends in zooplankton community composition were also related to changes in environmental characteristics of the river. Our results indicate that the changing water quality status of the Paniyala water pond affected the zooplankton diversity and abundance and such measure could be used as a biomonitoring tool to determine the ecological health of the pond. Prevention of ecological deterioration of this water body would greatly result in a more productive water body, rich in zooplankton and with better fisheries.

Further socialization is needed regarding the importance of paying attention to the basic nutritional needs of cattle. The use of local plants that are often used by the community, such as betel fruit, is a worthy study to be explored. However, people still do not know the other benefits contained in betel fruit. In order to obtain optimal results, the study was carried out with in vitro experiments. Data processing was performed using factorial completely randomized design with three replications. The treatment factors were differentiated based on the length of the betel fruit immersion process in ice water and the length of storage time. The analysis showed that cold storage of grass with betel fruit was successful in increasing the Volattile Fatty Acid component (P> 0.01). The habits of the people of West Papua in utilizing local plants, especially those with tannin, have been scientifically proven to be useful. Cold storage of betel fruit with the addition of grass as ration for cattle has a very significant effect on the levels of iC4 (as iso butyrate), nC4 (as n butyrate), iC5 (as iso valerate), and nC5 (as n valerate). In addition, the Papuan people's habit of adding local plants, especially betel fruit as additional feed has been scientifically proven to be useful.

Several species of the Myrcia genus have been used in folk medicine to treat diabetes. Therefore, the aim of this work was to investigate the inhibitory activity of α-glucosidase and pancreatic lipase in the crude extract (EBF) and in the ethyl acetate fraction (FFA) of Myrcia hatschbachii, as well as to identify isolated phenolic compounds and to evaluate the antioxidant property and preliminary in vitro toxicity against Artemia salina. EBF (IC50: 3.21 μg/mL) and FFA (IC50: 1.14 μg/mL) showed inhibitory activity superior to acarbose (IC50: 193.65 μg/mL). In addition, they showed inhibitory effects of pancreatic lipase (IC50: 556.58 μg/mL for EBF and 532.68 μg/mL for FFA), antioxidant potential, absence of preliminary toxicity and presence of gallic andellagic acids in FFA. The relevant results in the inhibition of α-glucosidase and pancreatic lipase motivate new studies for the development of herbal medicines that assist in the treatment of diabetic patients.

The aim of this study was to undertake a screening experiment on essential oils (EO) of Myrcia lundiana, Ocimum basilicum and Lippia alba against six food-spoiling pathogenic bacteria. Seventy-two (72) samples were initially analyzed for antimicrobial activity based on the agar diffusion test. The minimum inhibitory (MIC) and bactericidal (MBC) concentrations were determined for the 12 samples which showed greatest antimicrobial potential in this stage. Two samples of L. alba, three samples of M. lundiana and seven samples of O. basilicum showed a MIC of 0.12-125 μL/mL for the six tested bacteria. Of these, the EO of O. basilicum cultivar Maria Bonita stood out with the lowest MIC and MBC. Thus, a mixture simulating this essential oil was prepared from commercial standards of the compounds (±)-linalool, geraniol and 1,8-cineole. Significantly higher MIC and MBC were detected in the simulation compared to the respective EO, suggesting a synergistic effectbetween compounds.

In this present study, we investigated the influence of various extraction methods including maceration, sonication, infusion, decoction, and microwave extraction, on the chemical and biological potential of phytochemicals extracted from three medicinal plants (Ageratum conyzoides, Plantago major and Arctium lappa L). The results were subsequently analyzed by variance analysis. Our results suggested that sonication is the most effective extraction method among the five methods tested herein, for the extraction of phytochemicals that have a high antioxidant potential and high phenolic content. The three plants employed for this study had a high concentration of flavonoids and phenolics which was compatible with the chemosystematics of the species. All the samples possessed a Sun Protection Factor (SPF) of less than 6. Interestingly, a maximum reaction time of approximately 20 min was noted for the complexation of AlCl3with the flavonoids present in the phytochemical extract during analyses of the kinetic parameters. We finally identified that the Ageratum conyzoides extract, prepared by sonication, possessed a significant pharmacological potential against hepatocarcinoma tumour cells, whose result can guide further studies for its therapeutic efficacy.

Hochtransparente Gebäudehüllen ohne sichtbare Tragstruktur oder Treppen, die in der Luft zu schweben scheinen, sind der Traum vieler Architekten. Um diese gestalterischen Anforderungen zu erfüllen und trotzdem die Standsicherheit der gläsernen Struktur zu gewährleisten, kommt der Ausführung der Verbindungspunkte zwischen den Glaselementen eine wichtige Bedeutung zu. Die Verbindungspunkte stellen das verbleibende Sichtbare dar, somit rücken sie in den Fokus des Interesses beim Betrachten der Ganzglaskonstruktion. In diesem Artikel werden neue Ganzglaskonstruktionen mit dem besonderen Blick auf die Ausführung der so wichtigen Verbindungsdetails vorgestellt. Neben den Möglichkeiten von projektspezifischen Lösungen werden auch strukturelle transparente Klebverbindungen zwischen Metall und Glas erläutert.
Querkraftversuche an Spannbetondurchlaufträgern mit Plattenbalkenquerschnitt/Shear tests on prestressed concrete continuous beams with T-shaped cross section

Published: March 2021

Die Nachrechnungen bestehender, älterer deutscher Spannbetonbrücken auf Grundlage der aktuell gültigen Normen und Richtlinien zeigen im Allgemeinen erhebliche Defizite in Bezug auf die erforderliche Querkraftbewehrung. Im Zuge aktueller Forschungstätigkeiten im Auftrag der Bundesanstalt für Straßenwesen (BASt) wurden daher an der TU Dortmund Großversuche durchgeführt, um das Querkrafttragverhalten durchlaufender Spannbetonbalken genauer zu untersuchen. Daraus sollen Rückschlüsse auf zusätzlich vorhandene Querkrafttraganteile gezogen werden, welche derzeit bei der Bemessung mit dem idealisierten Fachwerkmodell nicht in Ansatz gebracht werden. Die wesentlichen Variationsparameter der experimentellen Untersuchungen waren der Querkraftbewehrungsgrad sowie die Belastungsart (Einzellast vs. Streckenlast). Der vorliegende Beitrag stellt die Versuche sowie ausgewählte Versuchsergebnisse und Erkenntnisse in kompakter Form dar.
Numerische Untersuchungen zur Durchstanztragfähigkeit von Flachdeckensystemen/Numerical investigations on punching shear capacity of continuous flat slabs

Das Durchstanztragverhalten von Stahlbetonplatten wird seit mehreren Jahrzehnten experimentell erforscht. Aufgrund des hohen Kosten- und Arbeitsaufwandes von Durchstanzversuchen an Flachdeckensystemen wurde der Großteil der vorhandenen Durchstanzversuche an isolierten Flachdeckenausschnitten durchgeführt. Die Geometrie der Versuchskörper wurde dabei mit dem Ziel gewählt, den Stützmomentbereich um die jeweils betrachtete Decke-Stütze-Verbindung zu simulieren. Günstige Einflüsse, die sich in Flachdeckensystemen zum Beispiel aus Momentenumlagerungen oder Druckmembrantragwirkung ergeben, können in diesen Versuchen nicht auftreten. Daher eignen sich die vorhandenen Versuche in erster Linie zur sicheren Abschätzung der Durchstanztragfähigkeit.

 

Aufbauend auf theoretischen und experimentellen Untersuchungen aus der Literatur, wird in diesem Beitrag die Durchstanztragfähigkeit von Flachdeckensystemen anhand von nicht-linearen Finite-Elemente-Simulationen genauer untersucht. Das verwendete numerische Modell wird zunächst anhand von Durchstanzversuchen validiert. Nachfolgend wird das Modell für weiterführende Parameterstudien verwendet, um die Unterschiede zwischen Flachdeckensystemen und –ausschnitten genauer zu analysieren. Die Ergebnisse der numerischen Untersuchungen werden abschließend dafür genutzt, einen praxistauglichen Ansatz zur Bestimmung der Durchstanztragfähigkeit von Flachdeckensystemen im Bereich von Innenstützen abzuleiten.

Welded tubular joints are widely used in structural engineering due to their excellent resistance and stiffness in contrast to open sections, as well as simpler end preparation. Welding residual stresses that occur in these joints after the welding process can affect their structural behavior. Some recent experimental studies have shown that this effect can be considerable. This study numerically evaluates the influence of welding residual stresses on the behavior of rectangular hollow section T joints. The paper consists of two parts. Part I develops and validates a finite element model for the joints directly taking into account welding residual stresses by means of an upstream thermomechanical simulation of the welding process. It is proven that particular attention needs to be paid to the discretization of the model, the material properties and the adequate description of the weld heat input. The validation with experimental results shows that the developed numerical model properly captures the local structural behavior of tubular joints and can be efficiently used for further investigations. Part II employs the constructed model to investigate the effect of welding residual stresses on the resistance and initial stiffness of the considered joints.

Imperfektionen, die bei Traglastberechnungen Berücksichtigung finden müssen, haben ihre Ursachen in Herstellungs- und Fertigungstoleranzen oder werden durch das Schweißen und den damit zumeist einhergehenden Nachbehandlungen in den Bauteilen hervorgerufen. Durch die Wärmewirkung des Schweißens entstehen sowohl sehr große Verformungen als auch signifikante Zug und Druckspannungen. Der strukturelle und geometrische Imperfektionsgrad wird somit maßgeblich von der Anzahl und der Lage der Schweißnähte sowie den Schweißparametern bestimmt. Für die Berücksichtigung in Traglastberechnungen ist ein physikalisch fundiertes Modell erforderlich, welches die Schweißimperfektionen schnell und präzise berechnet. Das gekoppelte analytisch numerische Hybridmodell erfüllt diese Kriterien. Die mathematischen Grundlagen des analytischen Modells sowie die Kopplung mit der numerischen Finite-Elemente-Berechnung werden eingangs vorgestellt und die Anwendung zur Berechnung von Verzügen an einer Schiffsektion demonstriert. Darauffolgend wird das Hybridmodell an einer eben und einer gekrümmten versteiften Platte zur Berechnung der Schweißimperfektionen angewendet. Anschließende Traglastberechnungen sowie der Vergleich mit den Ergebnissen unter der Annahme einer geometrischen Ersatzimperfektion in Form des kritischsten Eigenwerts gibt Auskunft darüber, welches Potenzial die realitätsnahe direkte Berücksichtigung von Schweißimperfektionen birgt.
