Authors: Qaraqe Marwa , Usman Muhammad , Serbes Ahmet , Ansari Imran Shafique , Alouini Mohamed-Slim
Published: March 2021

We present the concept of power HotSpots wherein the bigger satellites in low earth orbits (LEO), having power generation capacity much larger than CubeSats, can transfer their excess energy to CubeSats in need, using optical wireless technology. This provides a business opportunity for larger enterprises having the capability of launching bigger satellites to sell their power to CubeSats. As a proof of concept, this article presents a basic simulation regarding optical wireless power transfer (OWPT) to CubeSats. In addition, we highlight future research challenges in this area to maximize OWPT.
A Survey and Analysis on Automated Glioma Brain Tumor Segmentation and Overall Patient Survival Prediction
Authors: Agravat Rupal , Raval Mehul
Published: March 2021

Glioma is the most deadly brain tumor with high mortality. Treatment planning by human experts depends on the proper diagnosis of physical symptoms along with Magnetic Resonance(MR) image analysis. Highly variability of a brain tumor in terms of size, shape, location, and a high volume of MR images makes the analysis time-consuming. Automatic segmentation methods achieve a reduction in time with excellent reproducible results.

The article aims to survey the advancement of automated methods for Glioma brain tumor segmentation. It is also essential to make an objective evaluation of various models based on the benchmark. Therefore, the 2012 - 2019 BraTS challenges database evaluates state-of-the-art methods. The complexity of tasks under the challenge has grown from segmentation (Task1) to overall survival prediction (Task 2) to uncertainty prediction for classification (Task 3). The paper covers the complete gamut of brain tumor segmentation using handcrafted features to deep neural network models for Task 1. The aim is to showcase a complete change of trends in automated brain tumor models. The paper also covers end to end joint models involving brain tumor segmentation and overall survival prediction. All the methods are probed, and parameters that affect performance are tabulated and analyzed.

Development Life Cycle saw a huge business win in “Time to market”, over
several other advantages like risk aversion, flexibility, requirement
readjustments, collaboration etc. to name a few. This whitepaper elaborates on
the various salient features of DevOps that shapes the way software releases
are made today. DevOps is most suited to
Cloud and this paper explains the way the two technologies synergize. Service Oriented
Architecture is an architectural style that is essential in simplifying the
business and this paper explains how DevOps facilitates creation of granular
services that ultimately helps in attaining flexibility and agility of

Published: March 2021

In 2018, Lombok Island was hit by a series of destructive earthquakes. According to Indonesian Meteo- rological, Climatological, and Geophysical Agency data, about 1,973 felt earthquakes (M > 3) which shaken Lombok were recorded during August 2018 with three earthquakes with the largest magnitude of 6.9 Mw, 6.8 Mw, and 6.2 Mw. National Board for Disaster Management reported about 555 deaths, 1,833 people injured, and 186,010 houses damaged as a result of Lombok earthquake on August 5th, 2018. A number of seismometers were placed on Lombok Island from August 3rd, 2018 to October 19th, 2018 to monitor the aftershock events. There are 17 stations that record seismicity in Lombok consisting of 10 broadband sensors and 7 short period sensors. In this study, we used the Horizontal-to-Vertical Spectral Ratio (HVSR) method to analyze the risk of earthquake in the Lombok region. The basic concept of this method is to do a comparison between the horizontal component spectrum and the vertical component spectrum of a wave, where theoretically the particle movement of the horizontal component is greater than the particle movement of the vertical component on soft ground, whereas on the hard ground both components (horizontal and vertical) will be similar. H/V curve obtained from earthquake record- ings (Earthquake Horizontal-to-Vertical Ratio/EHVR) and H/V curve obtained from microtremor recordings (Microtremor Horizontal-to-Vertical Ratio/MHVR) shows good agreement and high correlation. Empirical correction of EMR (Earthquake-to-Microtremor Ratio) managed to decrease the difference of estimation of predominant frequency and amplification factor between EHVR and MHVR. Predominant frequency, amplification, and seismic vulnerability map agree with the geological condition of Lombok Island, where high value of amplification and seismic vulnerability was found on soft and thick ground. This study conclude that the maximum ground acceleration and the construction of the building should also considered when one wants to investigate the effect of an earthquake to the damage occurred, beside the site effects.
Study of P and S Wave Quality Factor (Qα and Qβ) Around Mt. Jailolo
Authors: Ulfiana Emi , Wandono Wandono , Sianipar Dimas Salomo , Heryandoko Nova
Published: March 2021

Mt. Jailolo is a B type volcano that has never  erupted after 1600. Seismic activities around Mt. Jailolo have never been recorded until the swarm in November 2015. Several studies have been done to determine thecause of the swarm, but it is not certain whether the cause of the swarm is tectonic or volcanic activities. The study of attenuation characteristics has never been carried out in the area around Mt. Jailolo. Attenuation characteristics are important to provide the medium information which seismic waves pass through and it can also be applied to the volcanic areas as preliminary disaster mitigation. The main objective of this study is to analyze attenuation characteristics often expressed by Quality factor (Q-factor) of P and S seismic wave (Qα and Qβ), which are inversely proportional to attenuation factor (1/Q). Calculations of Qα and Qβ are obtained using coda normalization method. The study area location is around Mt. Jailolo at 127.3◦ - 127.6◦E and 0.9◦ - 1.2◦ N. Data have been collected with 12 Short Period temporary 7G sensors network belongs to GFZ and BMKG. This study uses 147 swarm events from the sensors with a threshold magnitude of Mw< 5.0, during April 2017. The study obtains Qα(f) = 9.61814f 1.12981 and Qβ(f) = 19.10690f 1.22843. The current analysis concludes that the attenuation beneath Mt. Jailolo corresponds to the volcanic swarms which may have been triggered by its deeper layer’s magmatic activity.

Recent Topic of Saturated Fatty Acid (SFA) for Atherosclerotic Diseases
Authors: M Bando , H Bando
Published: March 2021

Whether saturated fatty acid (SFA) has a clinical influence on atherosclerotic cardiovascular disease (ASCVD) or not has been disputed. Prospective Urban Rural Epidemiology (PURE) study was recently summarized from 21 countries with about 150 thousand data. Dairy intake was negatively correlated with the prevalence of metabolic syndrome and the incidence of diabetes and hypertension. To increase the intake of dairy products would be easy and inexpensive to continue for treatment. Polyunsaturated fatty acid (PUFA) and monounsaturated fatty acid (MUFA) may reduce atherosclerotic diseases with beneficial effects. Clinical evidence of SFA will be hopefully accumulated for practice and research in the future.

Authors: Sumera Shabnum  , Nadeem Iqbal  , Haseebullah Khan
Published: March 2021

Brain drain is one of the important aspects of development economics/Demographic transitions. A populous country has the potential to export human capital. There are so many determinants of Human Capital Outflow (HCO). Some like economic, social, and political drivers are already discussed in the previous studies. This study compares the impact of various classes of variables on the HCO. Furthermore, it gives recommendations for controlling HCO based on such results. Data is collected in the form of questionnaires from three rural and three urban areas of Peshawar. Random sampling is used. Probit models are used for comparing the significance of variables. The study shows that not only the classic variables, i.e. economic, social and political are important but also the newly introduced religious and environmental factors have a great impact on HCO. The forthcoming researchers can do further study by considering even more factors affecting the HCO. They can conduct studies for different areas and on different scales.

Authors: Bobarykina Elena Nikolaevna , Khokhlov Viacheslav Aleksandrovich
Published: March 2021

The purpose of the research is to systematize the factors of formation of one of the directions of the market of industrial goods, namely, the market of electrical goods. Many works by both domestic and foreign authors, who present different points of view and approaches to the study of this phenomenon, are devoted to the functioning of local markets. The market of industrial goods and its component — the market of electrical goods-occupies its place among the local markets of the Russian Federation.
Exterial and internal factors of this market formation are considered, and dominant factors are highlighted. External, uncontrolled factors have a significant impact on the formation and implementation of the strategy of enterprises participating in the local market. Internal, controlled factors, in turn, are divided into stable and changing. Internal factors allow local market participants to respond to external factors in a timely and adequate manner and minimize their negative impact.
The current state of the Russian local market of electrical goods is characterized by the import dependence of some Russian manufacturers of electrical goods on separate product groups. The market is also characterized by growth, which is due to the strategic importance of this product for other sectors of the economy.
Modern trends in the development of the market of electrical goods are identified and analyzed, including the analysis of the structure and volume of production of electrical products in the context of domestic production and import revenues for selected groups of goods. The structure and dynamics of export deliveries of electrical goods are also analyzed in the context of the selected groups of goods and recipient countries.
Keywords: local market, electrical goods, demand, supply, import, export.
CREATING AN ENVIRONMENT FOR THE DEVELOPMENT OF A REGIONAL CLUSTER OF SOCIAL INNOVATIONS: A MARKETING APPROACH
Authors: Chernobaeva Gulnara Efimovna
Published: March 2021

Today, the cluster approach is one of the most effective models for developing territories. A cluster of social innovations requires the formation of a specific environment that ensures both the sustainable development of the cluster construct itself and the emergence of specific social innovations.
The aim of the research is to determine a set of tools based on the marketing approach for creating a unique environment that ensures the development of a regional cluster of social innovations.
The diagnostic approach allowed us to define the main archetype of social innovation as consumer. Factor analysis allowed us to assess the impact of a set of supply and demand factors on the success of social innovations. Factors of internal and external demand, infrastructure and cultural factors are identified as the main factors of the environment for the development of social innovations. Combining two groups of factors (ensuring the success of social innovations and the success of cluster development) in the absence of their superposition properties allowed us to determine the main tools for creating an environment for the development of a regional cluster of social innovations on the basis of a predictive approach. The specifics of the identified success factors of the regional cluster of social innovations formed the basis for choosing a marketing approach to the formation of the environment.
The formed environment of the regional cluster of social innovations should: ensure the growth of interest of all its potential cluster participants; demonstrate the availability of social initiatives; provoke successful innovations; form an effective system of information support for real and potential cluster participants; contribute to the integration of cluster management processes.

Authors: Blazhevich Oleg Georgievich , Bondar Aleksandr Petrovich
Published: March 2021

The essential approaches to the content of the financial security of the bank are considered and it was noted that the determination of the essence of the financial security of the bank can be carried out in the following logical sequence: bank security; economic security of the bank; financial security of the bank.
Important attention is focused on the elements of the bank’s financial security system. It was noted that the system for ensuring the financial security of a credit institution is a combination of elements that allow a bank to be a reliable, competitive participant in the banking services market.
The methodological aspects of using the integral method in the system of ensuring the financial security of a bank are presented. The assessment of the financial security of JSC » JSB» RUSSIA» was carried out on the basis of the integral method. As a result, it was revealed that the financial security of JSC » JSB» RUSSIA» is at a satisfactory level, which allows the bank and its clients to look confidently into the future, but the management of the credit institution must constantly pay attention to controlling emerging risks and conduct more efficient work in the competitive struggle in the market banking services in the Russian Federation.
The problematic aspects of ensuring the financial security of the bank were identified. The proposed integral indicator makes it possible to obtain a comprehensive assessment of the financial security of a bank, which will increase the efficiency of financial security management of banking institutions

Authors: Kiptum Andrew Rutto , Moraa Moturi Adelaide
Published: March 2021

We evaluated the influence of induced behavioural change on the community to adopt safe excreta disposal practices. This study was informed by unmerited programs which are majorly provided by most of the health organisations providing sanitary facilities rather than effective use which have failed to reduce the persistent occurrence of waterborne epidemics due to unsafe excreta disposal. Information sought in this survey was from two distinct populations of triggered and non-triggered villages of Turkana County, Kenya. Purposive sampling was used in identifying triggered and non-triggered villages, while systematic random sampling was used to administer structured questionnaires to respondents from identified sample units. From analysed data, the results showed latrine users from triggered villages were many compared with non-triggered villages. Again, the variable of education level, which showed to be critical, suggesting to influence latrine use among rural communities irrespective of the triggers. The parameter estimator of public health extension services and information sharing means from the neighbourhood showed to be statistically significant in influencing adoption and diffusion of health knowledge. In conclusion, involving health experts in knowledge diffusion and scaling up formal education among communities influences the adoption of safe excreta disposal practices. The significance of random factor in the OLS model, explains omitted and/or unobserved variables and existences of unclearly explained variables, informs the need for further investigation.
Helical Pile Capacity-to-Torque Correlation: A More Reliable Capacity-to-Torque Factor Based on Full Scale Load Tests
Authors: Souissi Moncef
Published: March 2021

The capacity-to-torque ratio, Kt, has been used in the design of helical piles and anchors for over half a century. Numerous research efforts have been conducted to accurately predict this capaci-ty-to-torque ratio. However, almost of all these Kt factors are based on shaft geometry alone. The ca-pacity-to-torque ratio described herein was found to depend on the shaft diameter, shaft geometry, helix configuration, axial load direction, and installation torque. In this study, 799 full scale static load tests in compression and tension were conducted on helical piles of varying shaft diameters, shaft geometry, and helix configurations in different soil types (sand, clay, and weathered bedrock). The collected data were used to study the effect of these variables on the capacity-to-torque ratio and resulted in developing a more reliable capacity-to-torque ratio, Km, that considers the effect of the variables mentioned above. The study shows that the published Kt values in AC358 (ICC-ES Acceptance Criteria for Helical Piles Systems and Devices) underestimate the pile capacity at low torque and overestimate it at high torque. In addition, and based on probability analysis, the predicted capacity using the modified Km results in a higher degree of accuracy than the one based on the published Kt values in AC358.
Use of Case Histories to Illustrate the Effect of Installation Activities on the Side Resistance of Pipe Piles in Plastic Soils
Authors: Saye Steven
Published: March 2021

This paper presents observations of the influence of pile installation methods on the measured side resistance of driven pipe piles bearing in plastic soils. Pile installation practices that can reduce the capacity of completed piles in plastic soils from that calculated include re-driving of piles after partial or full dissipation of excess pore water pressure, long installation times, slow jacking, the influence of surface casing in soft soils, and the use of vibratory hammers. Selected case histories are used to illustrate how deviations from rapid and nearly continuous pile installation can result in poor performance. Designers and Contractors need to be more aware of the damaging effects of these practices and that the selected design approach may not effectively consider the selected installation procedures. Where project requirements dictate use of these installation approaches that damage pile side resistance, the proposed construction influence factors may be used to modify a SHANSEP-based side resistance method to estimate the potential reductions in side resistance associated with the selected approach. Although the number of case histories available are too few to characterize the reliability of the construction influence factor approach, the cases sufficiently demonstrate the damage that can occur when these practices are used and the importance of construction procedures for driven pipe pile foundations that minimize or avoid damage to side resistance and to highlight where special design and testing are merited.
Engaging the importance of community scientists in the management of an invasive marine pest

The introduction of nonnative invasive pests is among the many threats facing coastal ecosystems worldwide. Managing these pests often requires considerable effort and resources, and community scientists can be essential for providing the capacity needed for management and monitoring activities. In response to the invasion of a Northern California estuary by the predatory European green crab, a collaborative team of academic researchers and community scientists initiated a local eradication program. The green crab is listed among the world's 100 worst invaders, and threatened both native species and commercial shellfisheries. The program dramatically reduced the green crab population over a 5-year period, but it rebounded, which necessitated a switch in project goals from eradication to population suppression. Community scientists were essential for facilitating this switch by providing the necessary capacity to quantify population characteristics and maintain reduced crab populations. The result was a sustainable program that successfully maintained low green crab densities, which will likely improve habitat for native species.
LCC-Modellierung von U-Bahn-Stationen: Teil 2 – Entwicklung eines Berechnungstools/LCC-Modeling of Metro Stations: Part 2 – Development of a Calculation Tool

In Zusammenarbeit mit dem österreichischen Verkehrsbetreiber Wiener Linien wurden die Lebenszykluskosten der Wiener U-Bahn-Stationen untersucht. Hauptaugenmerk der Untersuchungen lag auf den schwierig abzuschätzenden Folgekosten. Aufgrund der hohen Komplexität der U-Bahn-Stationen sind diese nicht mit anderen Gebäudetypen vergleichbar, weshalb bestehende LCC-Programme nicht geeignet waren, eine zuverlässige Prognose der Folgekosten zu erstellen. Daher entwickelten die Autoren mithilfe der mit den in diesem Forschungsprojekt unternommenen Untersuchungen gewonnenen Daten ein LCC-Berechnungstool speziell für die Wiener U-Bahn-Stationen. Dieses Berechnungstool ermöglicht die Abschätzung sowie Darstellung der Folgekosten und somit eine Optimierung dieser Kosten.

Berechnungsansatz zur Ermittlung der Schubtragfähigkeit bestehender Spannbeton- brückenträger mit geringem Querkraftbewehrungsgrad/Approach for the determination of the shear strength of existing post-tensioned bridge girders with a minimum amount of transverse reinforcement

Published: March 2021

Bei der rechnerischen Beurteilung der Tragfähigkeit älterer Spannbetonbrückentragwerke mit geringer Querkraftbewehrung stellt sich vermehrt heraus, dass die Querkrafttragfähigkeit nach dem aktuellen Normenstand oftmals nicht mehr erfüllt werden kann. Versuche zeigen jedoch, dass die derzeit anzuwendenden Berechnungsmodelle gerade für diesen Bauwerkstyp konservative Ergebnisse liefern. Es werden daher verfeinerte Rechenmodelle benötigt, welche es ermöglichen, diese Tragreserven zu nutzen. Der hier gezeigte Berechnungsansatz soll dieser Aufgabe gerecht werden. Es wird ein Nachweiskonzept neu aufgegriffen, welches die Nachweisführung in verschiedene Bereiche in Abhängigkeit der auftretenden Rissbildung einteilt. Da sich das Querkrafttragverhalten in den einzelnen Zonen grundlegend voneinander unterscheidet, kommt in den maßgebenden Bereichen ein dem jeweiligen Tragverhalten entsprechendes Berechnungsmodell zum Einsatz. Bei einem Vergleich des Ansatzes für die Bestimmung des kritischen Biegeschubrisses (FSC-Modell) konnte eine sehr gute Übereinstimmung mit Versuchsergebnissen aus der Literatur erzielt werden. Die statische Nachrechnung einer bestehenden Spannbetonbrücke mit geringer Querkraftbewehrung konnte darüber hinaus das große Potenzial des vorgeschlagenen Modells untermauern.

Green Building- und Nachhaltigkeits-Zertifizierungssysteme: Steuerungsinstrumente und Kommunikationstools für nachhaltige Immobilienentwicklung in Neubau und Bestand/Green Building certification systems: management instruments and communication tools for sustainable real estate development for new and existing buildings
Authors: Herzog Kati
Published: March 2021

Ein Zertifikat der drei in der deutschen Bau- und Immobilienbranche am weitesten verbreiteten Green Building und Nachhaltigkeits-Labels DGNB, LEED oder BREEAM ist der Beleg für nachhaltige Gebäudequalität und/oder nachhaltigen Gebäudebetrieb. Festzustellen ist, dass die Anzahl zertifizierter Gebäude weiter steigt und grüne Investments zunehmend an Bedeutung gewinnen. Jüngster Treiber dafür ist das wachsende Bewusstsein und die regulatorische Notwendigkeit der nachhaltigen Ausrichtung von Unternehmen im Hinblick auf ihre Corporate Responsibility. Die Zertifizierung der Nachhaltigkeit von Gebäuden sollte aber nicht nur als eine reine Auszeichnung eines Gebäudes und dessen Betrieb interpretiert werden. Der eigentliche Mehrwert entsteht, wenn die etablierten Nachhaltigkeitssysteme und -kriterien als Instrument zur Steuerung und Kommunikation verstanden werden, um Projekte und den Gebäudebetrieb nachhaltig zu entwickeln. Nachhaltigkeitskriterien lassen sich in Planung, Ausführung und Betrieb steuernd einsetzen, um die Projektziele von Investoren und Eigentümern erfolgreich umzusetzen. Das Nachhaltigkeitssystem mit den dazugehörigen Prozessen wird zum Managementtool, der Auditor als Nachhaltigkeitsexperte zum Nachhaltigkeitsmanager. Das Praxisbeispiel „Zukunftspark Wohlgelegen“ der Stadtsiedlung Heilbronn belegt, wie die Übersetzung einer Unternehmensphilosophie in einen Anerkennungsprozess für Green Building und die Nachhaltigkeitszertifizierung eines Gebäudes die erfolgreiche und nachhaltige Entwicklung des Quartiers stützt und Nachhaltigkeitskriterien sowie die dazugehörigen Prozesse als Steuerungsinstrumente und als Kommunikationstools eingesetzt werden können. Die abschließende Auszeichnung dieser Projekte ist die logische Konsequenz – aber kein Muss.
Bauen und Betreiben nachhaltiger Gebäude – Komplettierung der nationalen Bewertungsmethodik/To build and operate sustainable buildings – completion of the national assessment methodology
Authors: Weixler Otto Kajetan , Pohl Sebastian , Graubner Carl-Alexander
Published: March 2021

Die nationale Bewertungsmethodik für nachhaltige Gebäude gilt gemeinhin als Vehikel zur Systematisierung und Operationalisierung des abstrakten Nachhaltigkeitsansatzes in der Bau- und Immobilienwirtschaft, die als maßgeblicher Wirtschaftssektor damit gleichsam einen wichtigen Meilenstein in der Wahrnehmung ihrer unbestreitbaren Schlüsselrolle für eine nachhaltige sozioökonomische Entwicklung gesetzt hat. Trotz ihrer prinzipiellen Lebenszyklusorientierung bildete die nationale Bewertungsmethodik in ihren verfügbaren Systemvarianten, Nutzungsprofilen und Modulen bislang nicht alle Phasen und Facetten eines Gebäudelebenszyklus in einer unter Nachhaltigkeitsgesichtspunkten optimalen Granularität ab. Dadurch blieben nennenswerte Nachhaltigkeitswirkungen bzw. –potenziale des gesamthaften Gebäudelebenszyklus – namentlich prozessuale Aspekte der Bauwerkserstellung respektive der Nutzungs- und Betriebsphase – unberücksichtigt. Der nachfolgende Beitrag beschreibt neue wissenschaftliche und anwendungspraktische Erkenntnisse zur Steuerung, Optimierung und Bewertung der Nachhaltigkeitsqualität von Bauprozessen einerseits und des (prozessualen) Gebäudebetriebs andererseits und ist eine komprimierte Darstellung der Resultate zweier aktueller kooperativer Forschungscluster der Autoren.

Zur maximalen Durchstanztragfähigkeit von Einzelfundamenten mit einer neuartigen Durchstanzbewehrung/Maximum punching shear resistance of footings with a new punching shear reinforcement
Authors: Hegger Josef , Stark Alexander , Ricker Marcus , Kueres Dominik
Published: March 2021

Aufgrund der geringeren Schlankheit und der Belastung durch Bodenpressungen stellt sich bei Fundamenten und Bodenplatten ein Lastabtrag ein, der infolge der steileren Druckstrebenneigung höhere Durchstanztragfähigkeiten ermöglicht als bei Flachdecken. Die steileren Schubrisse führen jedoch dazu, dass vertikale Durchstanzbewehrungselemente weniger effizient sind als in Flachdecken. Aus diesem Grund scheinen geneigte Bewehrungselemente geeigneter für den Einsatz in Platten mit größerer Bauteildicke und geringerer Schlankheit. Aufbauend auf den Ergebnissen vorhandener experimenteller Untersuchungen an durchstanzbewehrten Einzelfundamenten wurde daher ein neues Durchstanzbewehrungselement mit geneigten Bewehrungsstäben entwickelt.

 

In einer ersten Versuchsserie wurden sieben Versuche an Einzelfundamenten mit der neuartigen Durchstanzbewehrung und einem Versagen innerhalb des durchstanzbewehrten Bereichs durchgeführt. Die Versuche wurden in Anlehnung an eine bereits bestehende Versuchsserie an Einzelfundamenten ohne und mit Bügeln als Durchstanzbewehrung geplant und zeigten im Vergleich eine erhebliche Steigerung der Durchstanztragfähigkeit.

 

Aufbauend auf den Ergebnissen der ersten Versuchsserie wurde eine zweite Versuchsserie durchgeführt, um die maximale Durchstanztragfähigkeit von Fundamenten mit der neuartigen Durchstanzbewehrung zu untersuchen. In den sieben Versuchen wurden die Betondruckfestigkeit, die Schubschlankheit, der bezogene Stützenumfang und die Anordnung der Durchstanzbewehrungselemente variiert. Der Vergleich der Bruchlasten der neu durchgeführten Versuchsserie mit der Durchstanztragfähigkeit nach DIN EN 1992-1-1+NA(D) belegt eine hohe Effizienz der neuartigen Durchstanzbewehrung.
