Generalized Yamabe Solitons on Hypersurfaces in Pseudo–Euclidean Spaces
Demirci, Burcu Bektaş; Fujii, Shunya; Maeta, Shun
In this paper, we obtain a classification theorem for generalized
Yamabe solitons, called conformal solitons, on pseudo–Riemannian
hypersurfaces in pseudo–Euclidean spaces by taking the vector field as
the tangential part of the position vector field. By using the theorem, we
also obtain complete classification of Yamabe solitons, almost Yamabe
solitons, k–Yamabe solitons and h–almost Yamabe solitons on pseudo–
Riemannian hypersurfaces in pseudo–Euclidean space under the same assumption.

Detecting Code Smell with a Deep Learning System
Nizam, Ali; Avar, Muhammed Yahya; Adaş, Ömer Kaan; Yanık, Ahmet
Code smell detection is one of the most significant
issues in the software industry. Metric-based static code analysis
tools are used to detect undesirable coding practices known as
code smells and guide refactoring requirements. Furthermore,
the usage of deep learning-based techniques has emerged in code
analysis tasks. The line and block level detection capability of
metric-based tools provides an advantage over deep learning
system systems. This study aims to develop a deep learning-based
system for inter-procedural code smell detection supporting line
and block of code. We created an experimental dataset by
gathering code from GitHub repositories and detecting code
smell on these codes using the metric-based SonarQube tool.
Recurrent neural networks and transformers implementations of
deep neural networks were applied to detect code smells. We also
employed cosine similarity and k-Nearest Neighbor machine
learning techniques for a comprehensive comparison. The
proposed system achieves an average accuracy of approximately
80%. These findings indicate that the proposed system can help
software teams in identifying potential interprocedural code
smells.

Characterizations of Loxodromes on Rotational Surfaces in Euclidean 3–Space
Aksoyak, Ferdağ Kahraman; Demirci, Burcu Bektaş; Babaarslan, Murat
In this paper, we study on the characterizations of loxodromes on the rotational surfaces satisfying
some special geometric properties such as having constant Gaussian curvature and a constant
ratio of principal curvatures (CRPC rotational surfaces). First, we give the parametrizations of
loxodromes parametrized by arc-length parameter on any rotational surfaces in E
3 and then, we
calculate the curvature and the torsion of such loxodromes. Then, we give the parametrizations
of loxodromes on rotational surfaces with constant Gaussian curvature. Also, we investigate
the loxodromes on the CRPC rotational surfaces. Moreover, we give the parametrizations of
loxodromes on the minimal rotational surface which is a special case of CRPC rotational surfaces.
Finally, we give some visual examples to strengthen our main results via Wolfram Mathematica

Genelleştirilmiş 1-Tipinden Gauss Tasvirine Sahip Minkowski Uzayının Yarı-Riemann Alt Manifoldları
Demirci, Burcu Bektaş
Bu makalede, genelleştirilmiş 1-tipinden Gauss tasvirine sahip Minkowski uzayındaki dönel yüzeyler ve regle alt manifoldları üzerine çalışılmıştır. İlk olarak, ikinci çeşit noktasal 1-tipinden Gauss tasviri ile genelleştirilmiş 1-tipinden Gauss tasviri kavramları arasındaki ilişki verilmiştir. Daha sonra, 3-boyutlu Minkowski uzayında sabit ortalama eğriliğe sahip tümden jeodezik olmayan herhangi bir yüzeyin genelleştirilmiş 1-tipinden Gauss tasvirine sahip olamayacağı ispatlanmıştır. Diğer bölümde, 13 uzayındaki bütün dönel yüzeylerin genelleştirilmiş 1-tipinden Gauss tasvirine sahip olduğu gösterilmiştir. Ayrıca, genelleştirilmiş 1-tipinden Gauss tasvirine sahip dönel yüzeylerle ilgili bir örnek verilmiştir. Son bölümde ise, Minkowski uzayındaki regle alt manifoldları üzerine çalışılmıştır ve genelleştirilmiş 1-tipinden Gauss tasvirine sahip silindirik regle alt manifoldları incelenmiştir.; In this article, we study on rotational surfaces and regle submanifolds of the Minkowski space with generalized 1-type Gauss map. First of all, we give a relation between notions of pointwise 1-type Gauss map of the second kind and generalized 1-type Gauss map. Then, we prove that any non-totally geodesic surface in 3-dimensional Minkowski space with constant mean curvature does not have a generalized 1-type Gauss map. In other section, we show that all rotational surfaces in 13 have generalized 1-type Gauss map. Furthermore, we give an example for the rotational surface having generalized 1-type Gauss map. In last section, we study the ruled submanifolds in the Minkowski space and we examine the cylindrical ruled submanifolds having generalized 1-type Gauss map.
