The objective of this work is the mathematical modelling and the numerical simulation of the stationary, laminar, and natural convection, in a confined square cavity (H = L) filled with two fluids (a mixture of nanoparticles of aluminum oxide and Al2O3 water) in one partition and pure water in the other partition. A porous conductive wall of thickness w (w = L/e) and thermal conductivity Keff constitutes the exchange surface between these two partitions. The fluid movement is modeled by the Navier-Stokes equations in the two partitions, while the porous medium is modelled by the Darcy–Brinkman equation. Comsol Multiphysics software is used to solve the system of differential equations that is based on the finite element method. The results are discussed with particular attention to the mean and local Nusselt number (Nu), streamlines and isotherms. A parametric study for Rayleigh number Ra (102 to 106), volume fraction j (0% to 10%), and Darcy number Da (10-7 to 10-2) is performed. The obtained findings show that the increase in Ra, Da, and j intensifies the flow and improves the thermal exchange on the cold wall. For Da £ 10-5, Nu remains practically low and the natural convection is being dominated by conduction. For Da > 10-5, an increase in Nu is observed and the flows tend towards a purely convective situation. Furthermore, an increase in the heat transfer coefficients is observed with the raise of the porous layer permeability, volume fraction and Rayleigh number.
Flow Topology around Low Reynolds Number Airfoils with Vortex Shedding
Authors: Che Ibrahim Che Intan Hartini , Abdullah Aslam
Published: January 2021

In depth studies on the vortex formation process as well as the periodic behavior of the reattachment profile have been mainly sparked by broad discussions on the flow topology. While the topology methodology is quite well established, the majority of airfoil types have still not been covered. In this study, six low Reynolds number airfoils were considered to investigate the separation bubble structure, vortex shedding and reattachment point. This was done by means of computational fluid dynamics simulations involving the airflow passing several Eppler and Selig models. The method was validated against an established mathematical relationship to indicate that both simulations and analysis technique were reliable. It was observed that the phenomena under investigation directly affect the airfoils aerodynamic performance. In particular, vortex shedding and big reattachment length contribute to the minimum lift. Moreover, high number of vortices in the separation bubble as well as secondary separation bubble result in maximum drag. The results which correspond to low Reynolds number airfoils are applicable in micro aerial vehicles field.

Published: January 2021

Yaşlanmanın en çok bilinen olumsuz sonuçlarından biri de immün sistemdeki zayıflama ve bunun sonucunda ortaya çıkan immün defisitler nedeniyle yeni veya daha önceden karşılaştığımız antijenlere hızlı ve etkili bir cevap verilememesidir. Yaşlanmanın immün sistem üzerine etkileri timus ve kemik iliğindeki B ve T hücreleri ve sekonder lenfoid dokulardaki olgun lenfositlerin fonksiyonlarının farklı düzeylerde azalması ile kendini belli eder. Bu nedenle yaşlı bireylerde bağışıklık sistemi herhangi bir tehdit karşısında kaldığında gençler kadar hızlı ve etkili bir immün cevap oluşturamamaktadır. Özellikle yaşlıların coronavirüs nedeniyle risk altında olduğu bir pandemi döneminde yaşlı çalışmalarının daha çok immün sistemdeki bu değişimler ve altta yatan moleküler olayların tanımlanması şeklinde planlanması ve belki de yaşlıların bağışıklık sisteminin desteklenmesi ile bu ve bundan sonraki olası viral salgınlarla etkili mücadele etmemizi sağlayabilecektir.

Derleme şeklinde yapılan bu çalışma, yaşlılığın sağlık boyutunu değerlendirirken yaşlılıkta meydana gelen immün sistem rahatsızlıklarına karşı alınabilecek önlemleri sosyal hizmet ilişkisiyle ayrıntılı bir şekilde irdeleyecektir. Bununla birlikte, bu çalışmanın merkezinde yer alan yaşlı yetişkinlerin refahını ya da yaşam kalitesini etkileyen faktörleri anlamak ileriki sosyal hizmet kuram ve çalışmalarına temel oluşturabilecektir.

Coronavirus and Influenza Viruses: An Overview of Their Differences and Similarities
Authors: TÜRKMEN Lale , KIVANÇ Aydın
Published: January 2021

SARS-CoV-2 is a new virus that is the cause of the current COVID-19 pandemic. We currently do not have a cure and immunity against this pathogen. Influenza viruses, on the other hand, are constantly evolving and undergo various levels of antigenic drift and shift that will become less recognizable by our immune system. This makes it difficult to develop a widespread effective influenza vaccine and also poses a risk of pandemics by leading to the emergence of new strains of zoonotic Influenza. Both Coronaviruses and Influenza viruses are enveloped RNA viruses and one of the primary pathogens affecting human respiration. COVID-19 and Influenza infections have similar transmission routes and symptoms. The reviewed literature indicates that there are important structural differences between COVID-19 and Influenza. These include differences in genome structures, surface proteins, number of strain and subtypes. In addition, incubation times, risk groups, asymptomatic transmission and transmission rate are important difference between the two viruses. However, unlike Influenza, the lack of vaccines and treatments for COVID-19 poses serious difficulties in controlling the spread of the disease. As a result, Coronavirus is spreading rapidly and due to the risk of possible co-infection with Influenza virus, it is extremely important to evaluate COVID-19 and Influenza infection together and developing public health measures accordingly.

Authors: AKTUĞ Cemile , GÖKTAŞ Sonay , GEZGİNCİ Elif
Published: January 2021

The systematic review was planned to examine the application time of antibiotic prophylaxis to prevent surgical side infections. The keywords, “antibiotic application time”, “antibiotic prophylaxis” and “surgical side infections”, were searched both in Turkish and English in Google Scholar, PUBMED, and EBSCO databases. A total of 5969 studies published between 2009 and 2019 were screened. After the literature review, 5 related studies that met the inclusion criteria were included in the study. Preoperative antibiotic prophylaxis and antibiotic application times were examined. In a study included in the study, it was shown that the risk of developing surgical site infection was reduced in patients who received antibiotics for proclactic purposes 60 minutes before incision line formation. In the remaining four studies, it was stated that prophylactic antibiotherapy applied 30 minutes before surgery minimizes the development of surgical site infection. It was revealed that the application of prophylactic antibiotherapy 30 minutes before the incision line minimizes the risk of infection in the surgical area and the literature should be supported by studies on the time of antibiotic administration.

Published: January 2021

In the work of Mukhin and Varchenko from 2002 there was introduced a Wronskian map from the variety of full flags in a finite dimensional vector space into a product of projective spaces. We establish a precise relationship between this map and the Plücker map. This allows us to recover the result of Varchenko and Wright saying that the polynomials appearing in the image of the Wronsky map are the initial values of the tau-functions for the Kadomtsev-Petviashvili hierarchy.
Solovay reducibility and continuity
Authors: Kumabe Masahiro , Miyabe Kenshi , Mizusawa Yuki , Suzuki Toshio
Published: January 2021

The objective of this study is a better understandingof the relationships between reduction and continuity. Solovay reduction is a variation of Turing reduction based on the distance of two real numbers. We characterize Solovay reduction by the existence of a certain real function that is computable (in the sense of computable analysis) and Lipschitz continuous. We ask whether thereexists a reducibility concept that corresponds to H¨older continuity. The answer is affirmative. We introduce quasi Solovay reduction and characterize this new reduction via H¨older continuity. In addition, we separate it from Solovay reduction and Turing reduction and investigate the relationships between complete sets and partial randomness.

What are the risk factors for human trafficking among African women?
Authors: Fernandez Pacheco Alises Gloria , García Navarro María del Mar
Published: January 2021

In April 2018, the Ödos Project was launched, a shelter pilot initiative for the care and support of migrant women with children promoted by a network of social organizations in Andalusia, Spain. This initiative is designed to offer women who show signs of being victims of trafficking the opportunity to abandon trafficking networks and to have an alternative migration process. This criminological study aims to develop an instrument with which to detect the risk indicators of women who are potential victims of trafficking for sexual exploitation. To this end, risk assessment parameters have been established for shelter residents. To create an ad hoc instrument, a four-phase study was conducted using mixed methodology, which resulted in an improved quantitative pilot questionnaire based on qualitative methodology. The sample used for this study comprised 41 people. Reliability analysis confirms that the indicators used have high internal consistency. The implications of the results for the application of prediction tools in transcultural contexts will be discussed.
Invisibility Cloak using Color Detection and
Segmentation with open CV
Authors: Puneet and Vasudha Bahl
Published: January 2021

Have you ever thought of making visible things invisible, just like the Harry Potter? Have you ever thought
how does one supersede backgrounds and add effects in a movie?
The cloak was magical and invisible in Harry Potter, the movie. As we know there is no magic and no
invisible cloak which exists in the world. It’s all about the graphicstricks.
The concept of an invisibility cloak is a mixture of science, fantasy, and the collective imagination. This paper
helps to create one’s own ‘Invisibility Cloak’.It will make use of Python and OpenCV module specifically
targeting Image Processing and Image Segmentation to create a false sense of invisibility in the frame. It will
explore how an object of a specific color or texture can be manipulated using the OpenCV library of python.
To achieve this, initially we’ll be capturing and storing the backdrop frame . Thereafter we’ll be identifying
the red coloured fabric by making use of the above mentioned algorithms. Then we’ll segment out the red
colored fabric by generating a mask and then finallywe’ll generate the final augmented(magical) output to
create Invisibility cloak. These steps are discussed deeper in thepaper.
Graduate University Admission Predictor
using Machine Learning
Authors: Aashish Singhal and Saurabh Gautam
Published: January 2021

With the increase in the number of graduates who wish to pursue their education, it has become more
challenging to get admission for the students in their dream university. Usually, newly graduate students are
not knowledgeable of the requirements and the procedures of the postgraduate admission and might spent a
considerable amount of money to get advice from consultancy organisations to help them identify their
admission chances. Giving the limited number of universities that can be considered by a human consultant,
however, this approach might be bias and inaccurate. Higher education in abroad universities generally
means we have many options like Canada, USA, UK Germany, Italy, Australia etc. But we are focusing on
only the students who want to do their Masters in America. Students who want to do masters in America
have to write GRE (Graduate Records Examination) and TOEFL (Test of English as a Foreign Language). Once
they have attended the exams they have to prepare their SOP (statement of purpose) and LOR(letter of
recommendation) which are one of the crucial factors they have to consider. These LOR and SOP plays a vital
role if the student was looking for any scholarship. Prospective graduate students always face a dilemma
deciding universities of their choice while applying to master's programs. While there are a good number of
predictors and consultancies that guide a student, they aren't always reliable since decision is made on the
basis of select past admissions. So, with increasing demand of further education, one must not be confused
in where to apply. Then the students have to choose the universities they want to study or apply, we cannot
apply to all the universities that will lead to lot of application fees. Here comes the problem that the student
doesn’t know to which university he might get admission. There are some online blogs which help in these
matters but they are not that much accurate and don't consider all the factors and there are some
consultancy offices which will take lot of our money and time and sometimes they will give some false
information.so our goal is to develop a model which will tell the students their chance of admission into a
respective university. This model should consider all the crucial factors which plays a vital role in student
admission process and should have high accuracy.

Published: January 2021

Visualizations of algorithms contribute to improving computer science education. The process of teaching and
learning of algorithms is often complex and hard to understand problem. Visualization is a useful technique
for learning in any computer science course. In this paper an e-learning tool for shortest paths algorithms
visualization is described. The developed e-learning tool allows creating, editing and saving graph structure
and visualizes the algorithm steps execution. It is intended to be used as a supplement to face-to-face
instruction or as a stand-alone application. The conceptual applicability of the described e-learning tool is
illustrated by implementation of Dijkstra algorithm. The preliminary test results provide evidence of the
usability of the e-learning tool and its potential to support students’ development of efficient mental models
regarding shortest paths algorithms. This e- learning tool is intended to integrate different algorithms for
shortest path determination.
Recommendation System
Authors: Vinay Kumar Saini and Jai Raj Singh Dr. ML Sharma C
Published: January 2021

Research paper recommenders emerged over the last decade to ease finding publications relating to
researchers’ area of interest. The challenge was not just to provide researchers with very rich publications at
any time, any place and in any form but to also offer the right publication to the right researcher in the right
way. Several approaches exist in handling paper recommender systems. However, these approaches
assumed the availability of the whole contents of the recommending papers to be freely accessible, which is
not always true due to factors such as copyright restrictions. This paper presents a collaborative approach for
research paper recommender system. By leveraging the advantages of collab- orative filtering approach, we
utilize the publicly available contextual metadata to infer the hidden associations that exist between
research papers in order to personalize recommen- dations. The novelty of our proposed approach is that it
provides personalized recommen- dations regardless of the research field and regardless of the user’s
expertise. Using a publicly available dataset, our proposed approach has recorded a significant improvement
over other baseline methods in measuring both the overall performance and the ability to return relevant and
useful publications at the top of the recommendation list.

“IVERY”- Interior Design Website
Authors: Gaurav Arora and Anu Rathee
Published: January 2021

The complexity of Web sites are increasing and transforming into Web applications that contain business
logic, interactivity, transaction handling and states. This phenomenon forces the Web developers to adapt
more traditional software engineering techniques to keep the Web applications error free, maintainable,
reusable, well documented etc.
Many Web developers do not use any engineering techniques at all and design mainly to create as
fashionable applications as possible with no regards on the application’s functionality. This results in
applications that are hard to maintain and with poor functionality.
The purpose with this thesis was to see if the use of a more traditional software engineering technique,
namely the Unified Modeling Language with the newly added Web Application Extension, resulted in a Web
application with good design regarding the maintainability of the application .
To investigate the maintainability of an application, the maintainability was further divided into three sub
criteria: extensibility, reusability and documentation. These three criteria were then applied on a case study
were a Web application was designed. From the analysis of the final design, using the three criteria, the
maintainability was derived.
The result of the entire investigation showed that the UML WAE had a good support for extensibility, fair
support for reusability and very good support for documentation. From these results the main conclusion was
derived, that the use of UML WAE resulted in good design regarding the maintainability.
However, the result is limited to our case study and the design created in that case. The result may have
been different if the three criteria had been applied on a different case. Another aspect to consider is that the
quality of a design is often dependent on the knowledge of the persons that carry out the design.
