Local Strain Measurement in Tensile Test for an Optimized Characterization of Packaging Steel for Finite Element Analysis
Authors: Knieps Fabian , Köhl Manuel , Merklein Marion
Published: April 2021

The continuous development of packaging steels for thickness reduction processes requires an advanced process design. This process is increasingly supported by finite element analysis to simplify tool construction and material selection purposes. Therefore, the fundamental basis is always the precise material characterization of packaging steel commonly based on tensile tests to determine flow curve and Lankford coefficients. However, due to strong temper rolling and the occurrence of slip bands, most packaging steels just show little elongation in tensile test. Therefore, a method of Paul et al. to determine the flow curve with digital image correlation (DIC) methods in the necking zone was applied in this work to meet the requirements of packaging steel. For the use of anisotropic yield functions, it is necessary to determine Lankford coefficients. Thus, a new method is proposed to measure Lankford coefficients locally with a DIC system in tensile test, also in case that no homogenous forming condition is reached. With the presented approaches the packaging steel TH415 was characterized. In order to validate the developed methods, a demonstrator was simulated with anisotropic yield function Yld2000-2d . The comparison between simulation and experiment showed clear improvements in simulation accuracy when using the newly presented methods for packaging steel.
Temperature Dependent Modelling of Fibre-Reinforced Thermoplastic Organo-Sheet Material for Forming and Joining Process Simulations
Authors: Gröger Benjamin , Hornig Andreas , Hoog Arne , Gude Maik
Published: April 2021

Joining and local forming processes for fibre-reinforced thermoplastics (FRTP) like hole-forming or variations of the clinching process require an in-depth understanding of the process induced effects on meso-scale. For numerical modelling with a geometrical description of a woven fabric, adequate material models for a representative unit cell are identified. Model calibration is achieved employing a mesoscopic finite-element-approach using the embedded element method based on tensile tests of the consolidated organo-sheets and a phenomenological evaluation of photomicrographs. The model takes temperature dependent stiffness and fibre tension failure into account.
A Finite Plasticity Gradient-Damage Model for Sheet Metals during Forming and Clinching
Authors: Friedlein Johannes , Mergheim Julia , Steinmann Paul
Published: April 2021

In recent years, clinching has gathered popularity to join sheets of different materials in industrial applications. The manufacturing process has some advantages, as reduced joining time, reduced costs, and the joints show good fatigue properties. To ensure the joint strength, reliable simulations of the material behaviour accounting for process-induced damage are expected to be beneficial to obtain credible values for the ultimate joint strength and its fatigue limit. A finite plasticity gradient-damage material model is outlined to describe the plastic and damage evolutions during the forming of sheet metals, later applied to clinching. The utilised gradient-enhancement cures the damage-induced localisation by introducing a global damage variable as an additional finite element field. Both, plasticity and damage are strongly coupled, but can, due to a dual-surface approach, evolve independently. The ability of the material model to predict damage in strongly deformed sheets, its flexibility and its regularization properties are illustrated by numerical examples.
Load Path Transmission in Joining Elements
Authors: Steinfelder Christian , Martin Sven , Brosius Alexander , Tröster Thomas
Published: April 2021

The mechanical properties of joined structures are determined considerably by the chosen joining technology. With the aim of providing a method that enables a faster and more profound decision-making in the spatial distribution of joining points during product development, a new method for the load path analysis of joining points is presented. For an exemplary car body, the load type in the joining elements, i.e. pure tensile, shear and combined tensile-shear loads, is determined using finite element analysis (FEA). Based on the evaluated loads, the resulting load paths in selected joining points are analyzed using a 2D FE-model of a clinching point. State of the art methods for load path analysis are dependent on the selected coordinate system or the existing stress state. Thus, a general statement about the load transmission path is not possible at this time. Here, a novel method for the analysis of load paths is used, which is independent of the alignment of the analyzed geometry. The basic assumption of the new load path analysis method was confirmed by using a simple specimen with a square hole in different orientations. The results presented here show a possibility to display the load transmission path invariantly. In further steps, the method will be extended for 3D analysis and the investigation of more complex assemblies. The primary goal of this methodical approach is an even load distribution over the joining elements and the component. This will provide a basis for future design approaches aimed at reducing the number of joining elements in joined structures.
A Method for Characterization of Geometric Deviations in Clinch Points with Computed Tomography and Transient Dynamic Analysis
Authors: Köhler Daniel , Sadeghian Behdad , Kupfer Robert , Troschitz Juliane , Gude Maik , Brosius Alexander
Published: April 2021

When joining lightweight parts of various materials, clinching is a cost efficient solution. In a production line, the quality of a clinch point is primarily controlled by measurement of dimensions, which are accessible from outside. However, methods such as visual testing and measuring the bottom thickness as well as the outer diameter are not able to deliver any information about the most significant geometrical characteristic of the clinch point, neck thickness and undercut. Furthermore, ex-situ destructive methods such as microsectioning cannot detect elastic deformations and cracks that close after unloading. In order to exceed the current limits, a new non-destructive in-situ testing method for the clinching process is necessary. This work proposes a concept to characterize clinch points in-situ by combining two complementary non-destructive methods, namely, computed tomography (CT) and ultrasonic testing. Firstly, clinch points with different geometrical characteristics are analysed experimentally using ex-situ CT to get a highly spatially resolved 3D-image of the object. In this context, highly X-ray attenuating materials enhancing the visibility of the sheet-sheet interface are investigated. Secondly, the test specimens are modelled using finite element method (FEM) and a transient dynamic analysis (TDA) is conducted to study the effect of the geometrical differences on the deformation energy and to qualify the TDA as a fast in-situ non-destructive method for characterizing clinch points at high temporal resolution.
Towards a new epidemiological definition of chronic rhinitis: prevalence of nasal complaints in the general population
Authors: Avdeeva K.S. , Fokkens W.J. , Reitsma S.
Published: April 2021

Background: Chronic rhinitis (CR) is currently defined as the presence of at least two nasal symptoms for at least 1 hour per day for more than 12 weeks per year. Such definition lacks evidence-based foundation. CR patients are often divided into ‘runners’ and ‘blockers’, although the evidence supporting such subdivision is limited. The aim of the study was to define CR, to estimate its prevalence and the proportion of ‘runners’ and ‘blockers’. Methods: Cross-sectional, questionnaire-based study in a random sample of participants representing the general population of the Netherlands. Results: The questionnaire was sent to 5000 residents of the Netherlands; the response rate was 27%. CR was defined as at least 1 nasal complaint present for more than 3 weeks per year. The prevalence of CR in the general population was 40%. Participants who would have been excluded by the former CR definition were shown to have a significantly higher VAS compared to the controls. The larger part of CR group was represented by non-allergic rhinitis (NAR): 70% vs 30%. There were 25% ‘Blockers’ and 22% ‘Runners’ in the CR group, whereas more than a half of the CR group could be classified in neither of these subgroups. Conclusion: Based on our data, we suggest that the current definition of CR should be revised and propose a new definition: at least one nasal complaint present for at least 3 weeks per year; although future studies are needed to further validate the proposed definition.

Published: April 2021

Water, sanitation, and hygiene (WASH) practices emerged as a critical component to controlling and preventing the spread of the COVID-19 pandemic. We conducted 131 semistructured phone interviews with households in rural Odisha, India, to understand behavior changes made in WASH practices as a result of the pandemic and challenges that would prevent best practices. Interviews were conducted from May through July 2020 with 73 heads of household, 37 caregivers of children < 5 years old, and 21 members of village water and sanitation committees in villages with community-level piped water and high levels of latrine ownership. The majority of respondents (86%, N = 104) reported a change in their handwashing practice due to COVID-19, typically describing an increase in handwashing frequency, more thorough washing method, and/or use of soap. These improved handwashing practices remained in place a few months after the pandemic began and were often described as a new consistent practice after additional daily actions (such as returning home), suggesting new habit formation. Few participants (13%) reported barriers to handwashing. Some respondents also detailed improvements in other WASH behaviors, including village-level cleaning of water tanks and/or treatment of piped water (48% of villages), household water treatment and storage (17% of respondents), and household cleaning (41% of respondents). However, there was minimal change in latrine use and child feces management practices as a result of the pandemic. We provide detailed thematic summaries of qualitative responses to allow for richer insights into these WASH behavior changes during the pandemic. The results also highlight the importance of ensuring communities have adequate WASH infrastructure to enable the practice of safe behaviors and strengthen resilience during a large-scale health crisis.
Fatma Aliye's Women Caharacters in the Public Space
Authors: SOYTÜRK Remzi
Published: April 2021

The concept of "public sphere”, which has been one of the main discussion topics of the academy since the 1980s, derives its basis from Jürgen Habermas' The Structural Transformation of Publicity, published in 1962. The bourgeoisie, whose influence has increased in European society, creates a public community in places such as halls, cafes, and clubs where it had critically discussed in the 18th century, and the influence of this community has spread to the public with the increase in the publishing of magazines and newspapers. The liberal public sphere, where people engage in cultural exchanges, was interrupted and collapsed by the revolutions that started at the end of the 19th century and the wars that continued afterward. There was limited public space in the Ottoman society that started with coffee houses (kahvehane) and reading houses (kıraathane) and continued with increasing publishing activities during the Meşrutiyet period. By actively participating in publishing activities, Ottoman women opened a new way in this public space and strengthened their positions. In this study, which considers the novels of Fatma Aliye, the first Ottoman female writer, chronologically, from the woman who is restricted to the house and has a secondary position against the male power (Hayal ve Hakikat), to the woman who becomes increasingly prominent in the public sphere and has her autonomous voice (Muhadarat, Refet, Udi) will be studied.

Authors:   Institute of Business & Technology, Karachi., Cheema Farooq-E-Azam
Published: April 2021

Purpose-Purpose of this conceptual study was to explore prospects of coaching and mentoring as a HRD intervention in the private sector organizations and government departments in Pakistan. This study was prompted by coaching and mentoring being an effective and efficient mode of employee development compared to traditional off-the-job classroom training programs. Methodology/Sampling-The study was based on comprehensive literature reviewed critically and the diverse factors affecting these two activities as tools of employee development identified including their prerequisites and possible barriers in the way of their introduction and application. The guidelines emerging from the relevant literature were used to make analysis of the internal and external organizational environments and Pakistani culture as a whole. Opinion on the national and organizational culture and other determining factors for the coaching and mentoring as HRD tool was based on wider observation and experience of the authors themselves. Findings-The study did not promise rosy prospects altogether. It concluded that factors like organizational and national cultures, line managers' attitude towards coaching and mentoring and the top managements' overall approach towards the human resource development did not favour introduction and practice of coaching and mentoring as HRD intervention in Pakistan; both private sector local organizations and government sector departments. Practical implications-The study is informative for the HRD practitioners who are ambitious in availing the contemporary HRD interventions including coaching and mentoring in Pakistan like society.

Published: April 2021

An analytical expression for the elastic interaction energy of radiation point defects of the dipole type with the basal dislocation loop of the hcp metal is obtained using the Green's function method for hexagonal crystals in the Krener approach. It was used for numerical calculation of the bias for the basal dislocation loop of zirconium in a toroidal reservoir. The toroidal geometry of the reservoir allows one to perform the calculation for a loop of any size and without any correction of the elastic field in its region of influence. The dependencies of the loop bias on its radius and nature are obtained for various shapes of dipole defects.

Authors: Rudychev V.G. , Azarenkov M.O. , Girka I.O. , Rudychev Y.V.
Published: April 2021

The radiation shielding from γ-quanta of the existing transport containers (TC) for transportation of spent nuclear fuel (SNF) is made of steel or steel plus Pb 25…30 cm thick and weighting ~ 60…80 t. The application of materials with high atomic number, dispersed (solids grinded to a powdery state) to the densities in the range 4 < ρ < 8 g/cm3, is investigated. Simulations based on the Monte Carlo method show that at the densities of dispersed depleted U larger than 5 g/cm3 and shielding thicknesses of more than 30 cm, the absorption of γ-quanta of SNF is greater than that of the shielding made of steel of the same thickness. The application of such materials, while the weight characteristics of the shields are not exceeded, provides radiation shielding for SNF with the high burnup rate and the smaller cooling time or larger amount of the transported SNF.

Published: April 2021

The structure of CVD carbon coatings synthesized in a hydrogen-methane mixture in the plasma of a glow discharge stabilized by a magnetic field using a pulsed power supply was studied by X-ray diffraction analysis and optical microscopy. The range of deposition parameters is determined, which ensure formation of polycrystalline diamond coatings. The coatings consist of diamond crystals with a clearly defined cut and the crystal lattice parameter close to the tabular value for natural diamond. The influence of the methane partial pressure in the gas mixture and the substrate temperature on the size and predominant orientation of diamond crystals in the coatings was determined. It is established that the use of the pulse mode and grounding of the substrate holder helps to improve the quality of diamond coatings.

Authors: Mamontov O.V. , Malyk B.O. , Tokarieva О.V.
Published: April 2021

The system of personnel protection from ionizing radiation in laboratories and industrial premises, where they work with radioactive substances and materials has been considered. A logical scheme in the form of a tree of failures and mathematical expressions for calculating the reliability of the protection system are presented. The coefficients of the influence of individual elements on the reliability of the system are determined. A quantitative analysis of the coefficients of influence made it possible to identify the most significant and most unreliable elements (“weak links”). In order to replace the “weak links”, a list of alternative elements and possible combinations of elements in the protection system has been compiled. Two risk management strategies are proposed. The first strategy involves minimizing the likelihood of failure of the protection system. The second is to minimize the cost of its operation. The possibility of achieving a positive effect has been demonstrated in both cases.
HYDROPHILIC FLORA OF URBANIZED TERRITORIES OF THE VYATKA-KAMA CIS-URALS (ON THE EXAMPLE OF CITIES OF THE UDMURT REPUBLIC)
Authors: Kapitonova O.
Published: April 2021

The flora of water bodies and watercourses in urban territories rarely becomes the object of special research. In the period from 1995 to 2015, we studied the flora of aquatic and semi-aquatic habitats (macrophyte flora) of six cities of the Vyatka-Kama Cis-Urals (VKCU) located on the territory of the Udmurt Republic (eastern European part of Russia): Izhevsk, Glazov, Sarapul, Votkinsk, Mozhga and Kambarka. The studied cities differ in their history, economy, size of the territory and population. It has been revealed that the macrophyte flora of the studied cities was composed of 302 species from 135 genera and 64 families, which makes up 80.3% of the species composition of the macrophyte flora of the VKCU. Izhevsk, the largest of the studied cities, has the richest hydrophilic flora (257 species). In the flora of the water bodies and watercourses of Glazov, 197 species were identified, in Sarapul – 153, in Votkinsk – 194, in Mozhga – 122 species. Kambarka, the smallest of the studied cities, has the second largest macrophyte flora (198 species). It has been established that in the macrophyte flora of the studied urbanized territories, the proportion of hydrophytes (“aquatic core” of the flora) ranges from 13.93% to 20.2% of the species composition of the flora. This is significantly lower than that in the macrophyte flora of the entire territory of the VKCU, where hydrophytes make up 25%. The reduction in the number of species of the “aquatic core” is due to the incomplete representation of ecotopes inhabited by hydrophytes on the territory of cities, as well as the pollution and transformation of their characteristic habitats within urban landscapes. This underlines the vulnerability of the “aquatic core” of the flora. In addition, rare and protected species are represented in the macrophyte flora of cities, the growth of which is often associated with large urban water bodies – factory reservoir ponds. It is concluded that the taxonomic richness of the studied flora depends not so much on the size of urban territories and their geographical location within the region under consideration, but on the presence and diversity of ecotopes inhabited by aquatic and semi-aquatic plants.

Authors: Guerrero Centeno Jennifer Adriana , Della Giovanna Patricia Silvia
Published: April 2021

Antecedentes: La hidradenitis supurativa (HS) es una enfermedad inflamatoria crónica relacionada con el síndrome metabólico(SM), con un mayor riesgo de comorbilidades cardiovasculares; por lo tanto, se debe mantener un alto grado de sospecha clínica frente al hallazgo de alguno de sus componentes.
Objetivo: Evaluar la prevalencia del SM en los pacientes con diagnóstico de HS en comparación con la población general.
Diseño: Estudio retrospectivo descriptivo.
Métodos: Se revisaron las historias clínicas y el archivo fotográfico de los pacientes con diagnóstico de HS que consultaron entre el 1/9/2017 y el 31/8/2019. Se analizaron las variables: sexo, edad, antecedentes familiares, tiempo de evolución, índice de masa corporal, obesidad abdominal, laboratorio (glucemia y perfil lipídico), presión arterial, tabaquismo, número y localización de las lesiones, gravedad clinicoecográfica, respuesta al tratamiento y evolución clínica.
Resultados: Se evaluaron 30 pacientes con HS valorados en nuestro servicio en los últimos 2 años; 23 mujeres y 7 varones. Predominó el grupo etario de 31-40 años. De ellos, 19 pacientes (63,3%) cumplieron con los criterios necesarios para diagnosticar el SM, hallazgo que no se relacionó con el grado de severidad de la HS.
Conclusiones: La prevalencia del SM en nuestros pacientes con HS fue del 63,3% con respecto al 27,5% de la población general. La importancia de este hallazgo radica en detectar de forma temprana y oportuna la presencia de este síndrome en los pacientes con HS para evitar el riesgo de comorbilidades cardiovasculares a futuro.

Para ello, se realizó una investigación mixta, descriptiva y analítica, en la cual se recolectó datos realizando encuestas, que permitió aplicar tres cuestionarios obteniendo información sobre la calidad del servicio de los establecimientos de EsSalud a nivel nacional. El estudio analizó las variables, aplicando los instrumentos a una muestra de 6000 personas. Según los resultados obtenidos, se concluyó que, durante el período desde el año 2017 al primer trimestre del año 2020, se mantuvo el mismo nivel de cobertura de aseguramiento de los usuarios. El principal problema presentado en la prestación de servicios de EsSalud, es el tiempo de dilación para la atención, de las principales razones para que los usuarios no asistan a los centros de salud. También se evidenció que el principal motivo para acudir a los centros de atención de EsSalud, es que los asegurados no requieren pagar para ser atendidos. Concluyendo que los elementos más satisfactorios del servicio son la atención médica y las cirugías, el aspecto con mayor deficiencia es la demora para la atención.
Surviving the winter: Tetramorium sibiricum n. sp., a new Central Siberian ant species (Hymenoptera: Formicidae)
Authors: Seifert Bernhard
Published: April 2021

A new species of the thermophilous Tetramorium caespitum species complex, T. sibiricum n. sp., is described from the Central Siberian region near Ulan Ude that has mean January temperatures of – 24 °C. The new species is clearly separable from the related species, T. indocile Santschi, 1927 and T. caespitum (Linnaeus, 1758), by exploratory data analyses of 35 phenotypic characters and by a discriminant analysis of seven phenotypic characters. A key to these three species, which all might occur in Central Siberia, is provided. The zoogeographic divide called the Reinig Line (De Lattin, 1967) is considered to be important in separating the ranges of Central and East Palaearctic ant species with less strong cold-hardiness. Based on images of type specimens, Tetramorium annectens Pisarski, 1969 is recognized as heterospecific from T. tsushimae Emery, 1925.

Authors:   Kosygin Russian State University, KOBOZEVA Darya
Published: April 2021

Modern trends in the field of social and labor relations, and, above all, aspects of pension reform, have significantly affected the position of citizens of late working age in the labor market. Given that the right to work is an inviolable civil right, the desire of many thousands of people to work should be considered as an important aspect of state and demographic policy, and employment policy, and in general — the socio-economic policy of the state. The article presents data reflecting the results of a secondary analysis of the results of a large-scale sociological study of A-RCPOR on the prospects of employment of citizens of retirement age. The study shows the attitude of citizens to work after reaching retirement age and their willingness to continue to perform their work duties.
LA NECESIDAD DE REFORMAR LA LEGISLACIÓN SOBRE CONTRATACIÓN PÚBLICA PARA LUCHAR CONTRA LA CORRUPCIÓN: LAS OBLIGACIONES QUE NOS LLEGAN DESDE EUROPA
Authors: MEDINA ARNÁIZ TERESA
Published: April 2021

la corrupción es un grave problema que perjudica el desarrollo económico, político y social de un país. Su generalización más allá de las fronteras nacionales, preocupa a todos los Estados. Es por ello que, junto a las normativas internas, en los últimos años se han multiplicado los convenios internacionales para prevenir y reprimir las conductas corruptas. En esa línea de actuación se encuentra también la Unión Europea y sus Estados miembros que, desde distintos frentes, vienen desarrollando una política global de lucha contra la corrupción. Uno de sus ámbitos de acción es el de la contratación pública al ser éste uno de los sectores más expuestos al riesgo de corrupción. Este artículo presenta alguna de las medidas adoptadas desde la normativa contractual para reducir el riesgo de favoritismo y corrupción en las adquisiciones públicas.

ustelkeria arazo larria da eta eragin txarra du herrialde baten ekonomia, politika eta gizarte garapenean. Estatuetako mugak gainditu dituenez, estatu guztien kezka da. Hori dela eta, estatuen barruko araudiekin batera, azken urteotan nazioarteko hitzarmenak ugaldu dira jarrera ustelei aurrea hartzeko eta horiek jazartzeko. Ildo horretatik ere doaz Europako Batasuna eta estatu kideak, eta fronte desberdinetatik, ustelkeriaren aurkako politika globala ari dira garatzen. Jarduketa eremu bat kontratazio publikoa da, sektore horretan ustelkeria errazago gerta daitekeelako. Artikulu honetan, eskuraketa publikoetan kutunkeria eta ustelkeria gertatzeko arriskua murrizteko hartutako neurri batzuk azaltzen dira.

corruption is a serious problem that is detrimental to the social, economic and political development of any country. Its extension across national frontiers is a source of concern for all States. Hence, in addition to specific domestic regulations, international conventions have multiplied in recent years to prevent and to curb corrupt practices. The European Union is also moving down this road and has developed a global policy to combat corruption on various fronts. One of its areas of action is public procurement; since 2004, Directives on public procurement have provided for the mandatory exclusion from the tendering process of those tenderers who have been convicted in a final sentence of offences involving corruption. The present article approaches the study of these measures and examines their contribution to the fight against corruption in the context of public procurement.

THE LANGUAGE OF THE INHABITANTS OF SVINIȚA AS AN ETNOGRAPHIC GROUP WITHIN THE BULGARIAN PEOPLE
Authors: ANDREY DANIELA
Published: April 2021

The inhabitants of the Sviniţa village in Mehedinţi County are Bulgarian natives who have preserved their ethnic identity and 15th-century dialect which shares common features with the one spoken in Novo Selo (Vidin). Bulgarian, Hungarian, Serbian and Romanian linguists have proved or, on the contrary, have put into question the Bulgarian origin of the population of Sviniţa, based on the study of its material and spiritual culture as reflected in local vocabulary, ethnonymy, onomastics, etc. This dialect represents both old and new grammatical features of Bulgarian, such as: the reduction of unstressed vowels: а:ъ (браздḁ), е:ъ (е) (бóлън); Bulgarian-specific reflexes ь:ъ, ър/ръ, ъл/лъ, (бърдо, бръв, вълна, ябълка) which are impossible to pronounce in Serbian; phonetic changes such as the elision of h (aiduk); the absence of the infinitive, etc. The presentation of this material is not intended to question the scientific value of previous works and earlier authors’ capacity to account for certain aspects of the history and language of the Bulgarian minorities in Oltenia, but rather aims at providing an overview of the abundant bibliography, mostly unknown to Romanian scholars, and at emphasising that the language and culture of this minority may still represent a viable subject for research.
КЪМ ХАРАКТЕРИСТИКАТА НА СМЕСЕНИЯ ЕЗИК НА ВИЕНСКИТЕ БЪЛГАРИ ОТ ВТОРО ПОКОЛЕНИЕ / TO THE CHARACTERISATION OF THE MIXED LANGUAGE
OF SECOND-GENERATION VIENNESE BULGARIANS
Authors: KOCHEVA ANA
Published: April 2021

Second-generation emigrants who preserve a number of features of the Bulgarian language exhibit bilingualism of a subordinate type. An active process of internal simultaneous translation of a subordinate type is still observed in these speakers. The dominant foreign (Austrian) environment determines the direction of interference. At present, the initial variability between Bulgarian and German language elements typical for first-generation emigrants has begun to disappear in the speech of the second gene-ration and a marked tendency towards the stabilisation of German elements – through direct or indirect borrowing (calquing) – is under way.

Authors:   Uniwersytet Warszawski, Solecki Mateusz
Published: April 2021

The article presents the issue of downburst over Poland. Strong downdrafts are a great danger in aviation, but can also cause damage on the surface of the Earth. On the basis of synoptic maps, aerological and radar data the analysis of synoptic and thermodynamic conditions of the atmosphere in which the phenomenon occurred was conducted. The appearance of the cold front over Lower Silesia and the occurrence of V-notch radar signature over Wroclaw may have suggested the formation of a storm and the associated downburst.

The exponential growth of the Internet of Things (IoT) technology poses various challenges to the classic centralized cloud computing paradigm, including high latency, limited capacity, and network failure. Cloud computing and Fog computing carry the cloud closer to IoT computers in order to overcome these problems. Cloud and Fog provide IoT processing and storage of IoT items locally instead of sending them to the cloud. Cloud and Fog provide quicker reactions and better efficiency in conjunction with the cloud. Cloud and fog computing should also be viewed as the safest approach to ensure that IoT delivers reliable and stable resources to multiple IoT customers. This article discusses the latest in cloud and Fog computing and their convergence with IoT by stressing deployment's advantages and complexities. It also concentrates on cloud and Fog design and new IoT technologies, enhanced by utilizing the cloud and Fog model. Finally, transparent topics are addressed, along with potential testing recommendations for cloud storage and Fog computing, and IoT.

Authors: Mistry Dharmin B , Agrawal Vimlesh V , Patel Vishal B
Published: April 2021

A staggered Truss System (STS) is a prospective steel structure system for high-rise buildings and a steel staggered truss framing system is one of the effective design techniques to improve the efficiency in building construction. Besides, cost reductions arise from a reduction in steel tonnage. The purpose of this study is to carry out a comparative analysis of staggered truss systems with and without a shear wall for 8, 9, and 10-storey buildings using the ETAB software. In this analysis, time histories are used. For the analysis, these structures are modeled in ETABS software and various displacement data are achieved for different types of structures. After analysis of the models, some outcomes were observed and it was concluded that the staggered truss system with the shear wall has lower displacement values compare to the staggered truss system in the x and y-direction. In the y-direction, displacement was 64% to 85% less and in the x-direction, it was 3% to 62% less than the conventional staggered truss system. So, after analyzing the data it was concluded that a staggered truss system with the shear wall is more efficient than the staggered truss system.
