    Physicochemical Properties of Some Drugs by Using Machine Learning
    (Library Information Services, COMSATS University Islamabad, Lahore Campus, 2025) Amman Farzeen; CIIT/SP24-RMT-023/LHR; Dr. Kashif Ali; LHR TP 10083
    This study explores the integration of machine learning and multi-criteria decision-making techniques for the characterization and evaluation of potential therapeutics targeting Duchenne Muscular Dystrophy . A dataset comprising the physicochemical properties of twenty anti- Duchenne muscular dystrophy drug candidates is analyzed using topological indices de- rived from molecular graphs. These indices, computed via Python-based algorithms, served as input features for machine learning models. Artificial Neural Networks and Random Forests are employed to predict key physicochemical properties based on the structural de- scriptors. The results demonstrate that topological indices are effective predictors, enabling accurate and consistent performance across both models. To prioritize the drug candidates, the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is applied as an multi-criteria decision-making tool, leveraging the model predictions to rank compounds based on multiple beneficial attributes. The proposed framework highlights the synergy be- tween graph-theoretical descriptors, machine learning, and multi-criteria decision-making, offering a robust in-silico approach for early-stage drug evaluation. This methodology pro- vides a systematic and objective strategy for ranking therapeutic candidates, particularly valuable in the context of rare diseases such as duchenne muscular dystrophy. Key words: Machine learning; Molecular Graph; QSPR Analysis; Topological indices; Ar- tificial Neural Networks; Random Forest; TOPSIS; Python Algorithm; Anti-DMD drugs.

    Entropy Measure of Degree Based Indices for the Boron Nanotubes
    (Library Information Services, COMSATS University Islamabad, Lahore Campus, 2021) Muhammad Shahid; CIIT/SP20-RMT-006/LHR; Dr. Kashif Ali; LHR TP 7624
    The physicochemical properties of molecules are correlated with their chemical struc- ture using degree-based topological indices. The graph entropy zone has captured the imagination of scientists because of its possible application in chemistry. Boron nan- otubular structures are high-interest materials with new electronic characteristics due to the presence of multi center bonds. Mechanical and thermal stability are two chal- lenges that these materials have in nanodevice applications. Therefor they necessitate theoretical research into the other qualities. In this thesis, study the graph entropy mea- sure by using topological invariants of different versions of atom-bond connectivity in- dex Zagreb indices M1(G), M2(G) (including redefined forms ReZG1(G), ReZG2(G) and ReZG3(G) and the forgotten topological index F(G)) which gives a better predic- tion of the chemical properties of different chemical compounds. We computed these indices for boron nanotube because of its significance in nanotechnology. To ensure the correctness of the output, a computational analysis and graphical comparison of generated indices is provided.

    Resolving Topological Index Of Graphs Associated
    (Library Information Services, COMSATS University Islamabad, Lahore Campus, 2021) Ali Bahadar; FA19-RMT-109; Dr. Kashif Ali; LHR TP 7394
    In this thesis, we study a well-known concept of graph theory, called resolvability, in con- text of two types of graphs ( commuting and non-commuting) associated to two algebraic structures (dihedral and semi-dihedral groups). By analyzing the resolving share and the average resolving share of each vertex, we compute the resolving topological index of each graph.

    Group H-magic labelings of graphs
    (Library Information Services, COMSATS University Islamabad, Lahore Campus, 2015) Syed Tahir Raza Rizvi; FA11-PMT-002; Dr. Kashif Ali; LHR TP 5283
    A simple graph G admits an H-covering if each edge in E G is a member of a sub- graph of G isomorphic to H. An H-magic labeling of a graph G possessing an H-covering is a bijective function from the vertex-set and the edge-set of the graph G onto the set 1 2 V G E G if there occurs a positive integer , called the magic sum, such that for every subgraph H of G isomorphic to H, the sum wt H v V H v e E H e is equal to . The sum wt H is termed as, the H-weight. A graph is called H-magic (H-supermagic) if it possesses an H-magic (H-supermagic) labeling. If H is isomorphic to K2, then resulting labeling is known as edge-magic total labeling. This dissertation studies about the formulation of cycle-supermagic labelings for the disjoint union of isomorphic and non isomorphic copies of different families of graphs. We also evaluate the K2-supermagic labelings of some families of alpha trees. More- over, we find the cycle-(super)magic labelings of uniform subdivided graph and cycle- supermagic labelings for non uniform subdivisions of fans and triangular ladders graphs. We also articulate about the introduction of H-groupmagic total labeling of a graph G over a finite abelian group A . In this study, we determine the H-groupmagic total labelings of fan graphs and disjoint union of isomorphic as well as non-isomorphic copies of fan graphs over finite abelian group A 3 n, where n 3

    Analytical and Soliton Solutions for Nonlinear Schr dinger Equation
    (Library Information Services, COMSATS University Islamabad, Lahore Campus, 2019) Badar Nawaz; CIIT/FA13-PMATH-001/LHR; Dr. Kashif Ali; LHR TP 5941
    A soliton which is also known as the traveling wave solution has a unique property,” the collision of two solitons produce the waves whose permanent structure remain the same”. These wave solutions are very stable and having a key role in the mathematical physics, especially in fiber technology. ”A soliton does not change its amplitude, shape and speed for a long distance in a non-local and nonlinear optical media”. The applications of soliton solutions are also in various branches of physics. The soliton solutions can be calculated by using the different types of nonlinearities. The optical solitons are very important in the study of nonlinear optical fibers. In this thesis firstly, we determine different types of soliton solutions of dimensionless form of Quintic Complex Ginzburg-Landau (CGLQ) equation by using modified extended tanh− function method (METFM) and the extended trial equation method (ETEM). Sec- ondly, we obtain bright, singular and Jacobi elliptic soliton solutions for the time fractional perturbed NLSE (TFPNLSE) by using ETEM with Kerr, power and log law nonlineari- ties. Thirdly, we find the combo and dipole soliton solutions for CGLQ model with differ- ent ansatz methods. Next, we construct different soliton solutions for the paraxial NLSE (PNLSE) in Kerr media by ETEM. Then, we get the bright and dark solitons for non- Kerr law NLSE with third order (3OD) and fourth order (4OD) dispersions by Sine-cosine method (SCM)and Bernoullis equation method (BEM) with nonlinearities. In the last, by using Hirota bilinear method (HBM), we obtain the multiple solitons for the nonlinear Telegraph equation (NLTE) and the nonlinear PHI-four equation (NLPFE).

    Chemical graph theory is a branch of mathematical chemistry that uses graph theory techniques mathematically create the chemical phenomena. In addition, chemical graph theory refers to the applications of graph theory to solve molecular chain. In the field of chemical research this theory has important applications. In this thesis, we find the some topological indices and the estimated values of these indices. We determine some entropy of degree based indices of different chemical structures especially the dendrimers and para-line graph and we research the entropies of the graph linked to a new information function accessible. We explore topological indices M1(G)andM2(G), the redefined form of Zagreb indices, the F-index F(G);R(G) index of the molecular chain especially the dendrimers. Furthermore, we compare the predicted values of these indices and give the graphical representation of these indices.
