Authors: Nagaraju Mr. M
Published: July 2022

Abstract: While in taking online classes or in day-to-day activities writing is more important task, as we are living in digital age which means most of our tasks are been shifted to digital trends such as like paying bills, booking tickets, emotion tracking etc., among this writing is at most important task weather you share ideas plan for a particular task taking notes, in this data age stats show humans more often prefer to write and use about 100 pages per average. It is quite our instinct to understand and represent any information which is written in handwriting, but when it comes to digitalworld though they are gesture based, touch based methods they couldn’t match the natural hand-write representation. So, we come with solution for this problem forsome extent by using hand tracking and hand landmark position representation whichis offered by media pipe library form google. This technique uses image processing (OpenCV) to capture video from webcam which will be given to our python application which uses media pipe library to recognize hand and represents it as 0-20 landmark positions. Which will be used to find index finger for writing and use two fingers for removing or erasing pre-written information. This type of application isvery useful in a day to day basic activates for students, teachers and makers in order to easily plan and organize projects, notes etc., Though this technique neither match areal writing experience nor the writing tablet for computers and smartphones which can translate our writing into digital notebook, it does not require any additional equipment and can be easily used to if practiced. This type of application can improvise the understanding by allowing users to explain in a whiteboard like environment in online education.
Enhanced Spectrum Handoff Security Mechanism in Cognitive Radio Network
Authors: Singh Ravendra Kumar
Published: July 2022

Abstract: In this work we introduce a novel cognitive user emulation attack (CUEA) in a cognitive radio network (CRN), which can be exploited by intruders during spectrum handoff. Then, we propose a secure handoff mechanism that can successfully counter such an attack by introducing a coordinating cognitive user that computes the level of trust of each cognitive user based on its behavioral characteristics. Malicious users can be effectively identified by the coordinating cognitive user by looking up the trust values. The performance of the proposed mechanism is validated using MATLAB simulations. The simulation results show that the utility of the proposed mechanism in terms of its probability in correctly identifying false authentication, detection rate, throughput rate, and transmission delay.
KYC Verification Using Blockchain
Authors: N V Sunitha
Published: July 2022

Abstract: The Know Your Customer process that exists today is inefficient and inconvenient for both banks and customers. The procedure is unnecessary and increases operating expenses. Furthermore, it offers little to no privacy protection to users. A blockchain-based method is proposed in this paper. Because documents are maintained by a centralised organisation, verifying KYC documents for multiple financial sectors is a time-consuming and insecure process. The proposed KYC system is a Blockchain-based decentralised system that can be used to establish proof of identity for an individual person. It is also a costeffective method, and the data stored on the decentralised application provides an additional layer of security.

Published: July 2022

Abstract: Due to the day-by-day innovations and development in construction field, the use of natural aggregates is very high and at the same time production of solid wastes from the demolitions of constructions is also very high. Because of these reasons the reuse of demolished constructional wastes came into the picture to reduce the solid waste and to reduce the scarcity of natural aggregates. Crushed waste tiles are used as a replacement to the coarse aggregates. The waste crushed tiles were replaced in place of coarse aggregates by 10%, 20%, 30%, 40%, and 50% without changing the mix design. M20 grade of concrete was designed to prepare the conventional mix. Without changing the mix design different types of mixes were prepared by replacing the coarse aggregates at different percentages of crushed tiles. Experimental investigation like Compressive strength test, workability for different concrete mixes with different percentages of waste crushed after 7, 14 and 28days curing period. Variations in the workability and compressive strength for these different mixes were studied and observed the optimum mix. Add nylon fibers from 0 to 2% with an interval of 0.5% to the optimum mix for improving the strength characteristics.

Authors: Saji Ms. Ansu P. , Priya R. Ms. Lekshmi
Published: July 2022

Abstract: As per IS 456:2000, deep beams can be defined as the structures that having span to depth ratio less than 2 for a simply supported beam and 2.5 for a continuous beam. Also these members are loaded on one face and supported on the opposite face. Uses of curved deep beams are increasing in structures like rounded corners of buildings, circular balconies, water tanks etc. Steel Fiber Reinforced Concrete (SFRC) is a concrete with short, discrete lengths of steel fibers which are randomly dispersed. The load deformation behavior of curved deep beam of different curvatures gives an idea about the effect of curvature on the performance of curved deep beam. The structure that generates comparatively small deformation within the applied load can be considered as relatively safe. This paper illustrates the effect of curvature or central angle on the ultimate load behavior of SFRC curved deep beam and analyzing its flexural behaviour. Steel Fiber Reinforced Concrete with 1% steel fiber is used in the current study. The central subtended angles adopted for the study are 00 , 450 , 600 , 900 , 1200 , and 1800 . As the central subtended angle increases, curvature also increases. The analysis of the structure has been carried out using ANSYS Software

Published: July 2022

Abstract: Concrete Filled Double Skin Steel Tube (CFDST) columns are modified form of Concrete Filled Steel Tubular (CFST) columns, developed by several researchers. CFDST column composed of two concentric steel tubes in which concrete is packed in between them. It is available in various geometrical shapes. CFDST have many advantages such as high strength, high bending stiffness, good seismic and fire performance. But it is found that CFDST columns have some disadvantages including ageing of structures, corrosion of steel tubes etc. which reduces the strength of the column. So, to prevent these drawbacks and to strengthen the structure, Glass Fiber Reinforced Polymer (GFRP) can be used as an external cover. The present study aims to do nonlinear static analysis of CFDST columns having different hollow ratio wrapped with and without GFRP under axial compression using ANSYS finite element analysis software.
Recycling Cupola Slag in Concrete as Partial Replacement of Fine Aggregate for Sustainable Construction
Authors: Bhat Sameeulah
Published: July 2022

Abstract: In the current study an effort has been made to investigate the impact of cupola slag inclusion, on the mechanical and durability properties of concrete. Different percentages (10%, 20%, 30%, 50%, and 80%) of cupola slag were used to substitute fine aggregate and corresponding results have been observed. Also, different mechanical and durability tests were carried out to check the suitability of replacing natural fine aggregate by cupola slag. Compressive strength was found to be increased by cupola slag inclusion up to a percentage replacement of fine aggregates of 30%, after which further cupola slag addition resulted in a loss of strength. For flexural and tensile strength similar trends were observed. On the other hand, as the amount of cupola inclusion increased from 0% to 80%, a decreasing trend in both water penetration depth and water absorption was observed. Likewise, for all the aforementioned criteria a notable improvement in chloride penetration was observed due to the inclusion of cupola slag. The study basically focuses on present concern regarding industrial waste which poses a risk to the environment. Industrial waste has been utilized in a sustainable manner, as it has shown improvement in properties as compared to ordinary concrete mix. Such type of modified concrete can be employed in harsh exposure conditions as can be found from durability tests. The findings of this study show that cupola slag is a sustainable matter that works well as a partial replacement for natural sand.

Authors: Kumar Mr Ashil S. , R. Ms. Lekshmi Priya
Published: July 2022

Abstract: The bound bridge is in the position of the bridge where the external horizontal force of the upper singing unit is carried as the lowest volume of the bridge. This removal of horizontal forces in connected areas allows for bound bridges to be created with slightly stronger foundations. Therefore, bounded bridges may be located at higher elevations or created in areas with unstable soil conditions. That the structure does not depend on the horizontal compression force for its integrity in the associated arch bridge. Combined bridges may be out of place, and may later be covered locally. The flexible reaction of a hardpressed concrete bridge under an earthquake load is investigated using a limited portion of the model in the ANSYS software package. A bridge identified as the New Kozhencherry Bridge in Kerala, India has been selected for research. The bridge is a proposed project of the Department of Public Works, Kerala. My paper mainly focus on investigate the performance of frequency influence of vehicle load in bridge.

Rural development has become a significant policy challenge in Europe. More employment opportunities have increasingly been concentrated in urban areas, leaving rural regions with ever-continuing down-fall in terms of population size and economic growth. In this context, rural entrepreneurship activity that positively influences rural communities is embedded in broader social or structural policies at the European level. The aim of the article is to investigate societal and economic challenges and their innovative solutions in five European rural regions: Croatia (Slovania), Germany (Münsterland, Saxony-Anhalt), Poland (Małopolska), and Portugal (Alto Minho). This study follows a multi-case method which investigates the diversity of challenges and solutions in selected European rural areas. The comparative analysis reveals that most essential activities aimed at alleviating the development problems of rural areas include education of local communities, improvement of economic and digital infrastructure, activities supporting production and promotion of local products, promotion of cooperation between local communities and producers, and stronger orientation of local policy towards financial support of production enterprises and farms. The conclusions resulting from the study lead to formulating recommendations concerning rural policies in the context of developing entrepreneurship strategies in rural areas.

Interest groups and electronic waste management policy
Authors: Duangthong Thanya , Boonmee Theerayuth
Published: July 2022

The world is now seeing a surge in electronic waste, often known as “e-waste”, and Thailand is Southeast Asia’s second-largest generator of e-waste (Forti, Baldé, Kuehr, & Bel, 2020; The Momentum, 2018). Since the bulk of policymakers is linked with interest groups and political pressures, Thailand has been collecting such issues for a very long time. Thus, the relationship between interest groups and policy in Thailand’s e-waste management was investigated using qualitative methodologies, an in-depth interview, and documentary research. The findings noted that the current e-waste management bill may be advantageous to all sectors since it offers realistic rules and effective mechanisms for e-waste management. Prior to the Waste Electrical and Electronic Equipment Management Act’s implementation, a number of issues must be reviewed, including the determination of the e-waste product type, insufficient law enforcement, a suitable take-back mechanism, public education, waste management technologies, and responsibility distribution. Moreover, several studies have demonstrated the connection between interest groups and e-waste management. Priority should be given to educating the public about the need for electronic waste management, followed by allocating duties to each sector equitably and appropriately.
Shareholder activism: A Swiss case study
Authors: Rautenstrauch Thomas , Hummel Janis
Published: July 2022

This article examines the phenomenon of shareholder activism using a case study methodology as a qualitative research approach. Three affected Swiss public companies have been selected on the basis of an evaluation of all corresponding reports published by Finanz und Wirtschaft (FuW). The study covers the period from 2015 to 2019. The chosen companies, Meyer Burger, GAM (Global Asset Management), and Clariant, were examined over this period. Our results show, that individual activist investors were able to generate substantial profits for themselves during the period studied, but not in a long-term and sustainable manner. Shareholder activism manifested itself in various forms and strategies within the scope of the individual cases. However, we were able to identify a general scheme of engagement for shareholder activists. Our research further shows that interests between long-term investors and management often collide when it comes to decisions about mergers and acquisitions (M&A). This results in shareholders tending to engage in shareholder activism as a countermeasure in order to enforce their demands

measure of landscape environmental heterogeneity. As descriptors of ant
community structure, we considered species composition, community
evenness, and functional response traits. We found that extensively
grazed pastures and within-site heterogeneity in soil moisture at local
scale, and a high diversity of land cover types at the landscape scale
affected ant species composition by promoting nest densities. Ant
community evenness was high in wetter grasslands with low within-site
variability in soil moisture and surrounded by a less diverse landscape.
Fourth-corner models revealed that ant community structure response to
environmental heterogeneity was mediated mainly by worker size, colony
size, and life history traits related with colony reproduction and
foundation. We discuss how within-site local variability in soil
moisture and low intensity grazing promote ant species densities, and
highlight the role of habitat temperature and humidity affecting on
community evenness. We hypothesize that a higher diversity of land cover
types in a forest-dominated landscape buffers less favorable
environmental conditions for ant species establishment and dispersal
between grasslands. We conclude that spatial environmental heterogeneity
at local and landscape scale plays an important role as deterministic
force in filtering ant species and, along with neutral processes (e.g.
stochastic colonization), in shaping ant community structure in
temperate semi-natural upland grasslands.

Group VII Ethylene Response Factors (ERF-VII) are plant-specific
transcription factors (TFs) known for their role in the activation of
hypoxia-responsive genes under low oxygen stress but also in plant
endogenous hypoxic niches. However, their function in the
microaerophilic nitrogen-fixing nodules of legumes has not yet been
investigated. We investigated regulation and the function of the two
Medicago truncatula ERF-VII TFs ( MtERF74 and
MtERF75) in roots and nodules, MtERF74 and MtERF75
in response to hypoxia stress and during the nodulation process using an
RNA interference strategy and targeted proteolysis of MtERF75. Knockdown
of MtERF74 and MtERF75 partially blocked the induction of
hypoxia-responsive genes in roots exposed to hypoxia stress. In
addition, a significant reduction in nodulation capacity and nitrogen
fixation activity was observed in mature nodules of double knockdown
transgenic roots. Overall, the results indicate that MtERF74 and MtERF75
are involved in the induction of MtNR1 and Pgb1.1
expression for efficient Phytogb-NO respiration in the nodule.

This case report describes a unique approach in the treatment of a
patient with severe crowding by an orthopaedic widening of the dental
arches using a skeletally anchored rapid palatal expander. This approach
can serve as a robust alternative to extractions and can be effective in
a variety of situations.

Published: July 2022

Currently the onset of bone damage and the interaction of the cracks
with the surrounding micro-architecture are still a black box. Motivated
to address this issue, our research aims at isolating lacunar
morphological and densitometric effects on crack advancement under both
static and cyclic loading conditions, by implementing static extended
finite element models (XFEM) and fatigue analyses. The effect of lacunar
pathological alterations on damage initiation and progression is
evaluated; the results indicate that high lacunar density considerably
reduces the mechanical strength of the specimens, resulting as the most
influencing parameter among the studied ones. Lacunar size has lower
effect on mechanical strength, reducing it by 2%. Additionally,
specific lacunar alignments play a key role in deviating the crack path,
eventually slowing down its progression. This could shed some light on
evaluating the effects of lacunar alterations on fracture evolution in
presence of pathologies.

Learning traditional singing in Serbian clubs in Vienna - economic aspects between amateurism and professionalism
Authors: Rasic Milos
Published: July 2022

Serbian clubs in Vienna are cultural, artistic, and sports organisations
formed in the 1970s by Yugoslav guest workers, then called Yugoslav clubs.
Since the 1990s, due to significant socio-political changes in the home
country, the work policies of clubs in Vienna have changed, and they have
become Serbian clubs. To learn traditional singing within the folklore
sections of the mentioned clubs, the leaders hire pedagogues from Serbia -
ethnomusicologists or individuals with completed secondary music schools in
the departments of traditional sing?ing. This paper aims to present and
analyse several aspects of learning traditional singing in these
institutions, focusing on the exchange of different forms of capi?tal - from
economic to symbolic and vice versa and reviewing the role of individ?uals
in these systems.
Gender differences in nightmare characteristics following trauma

Published: July 2022

Gender is one of the well-recognized risk factors for idiopathic nightmares, but rarely connected to posttraumatic nightmare characteristics. Thus, this study aims to test gender differences in (posttraumatic) nightmare characteristics after controlling for trauma-related psychopathology in a large sample of people who experienced trauma. Research participants were 707 soldiers (mean age 31.3 years, 19.5% women) admitted to a hospital-based treatment program for veterans who completed extensive assessments consisting of clinical interviews and self-rating measures with respect to socio-demographic characteristics and psychopathology, as well as dream-related variables. Results indicate no gender differences with respect to nightmare frequency, psychophysical and emotional involvement, reorientation, and dream recall after awakening. Differences between men and women in the amount of replicative content are fully, and in case of nightmare related impairment, explained mainly by the presence of PTSD diagnosis, nightmare frequency, and age. This study questions the significance of gender as a risk factor or predictor of specific (posttraumatic) nightmare characteristics in traumatized and military samples. Further research needs to test if our findings are restricted to military contexts or can be generalized to civilian samples.
