In this study, we explore the potential of graph neural networks (GNNs), in combination with transfer learning, for the prediction of molecular solubility, a crucial property in drug discovery and materials science. Our approach begins with the development of a GNN-based model to predict the dipole moment of molecules.

Rubberized concrete is a material that is both ecologically friendly and sustainable, and it has been finding more and more usage in building applications recently. In this study, a machine learning model, namely LightGBM, is developed to predict rubberized concrete's compressive strength (CS) using 11 input parameters.

In this research, Molecular Dynamics (MD) simulations were conducted to explore the temperature effect on the microstructure and phase transition of the Ag0.25Au0.75 alloy. The findings reveal that as the temperature rises, the material's phase transition switches from crystalline to liquid and vice versa.

Dredging plays a crucial role in port management, but disposing dredged material in the ocean raises environmental concerns. In recent years, this practice has become more prevalent in Vietnam. This study examined the dispersion of total suspended solids (TSS) in seawater from the submersion of dredged material in Vung Ang Port, northern Vietnam, to evaluate the environmental impact.

Welcome to the section that really makes this book unique. In my opinion, one of the best ways to prepare for the DB2 9 Fundamentals certification exam (Exam 730) is by answering sample questions that are presented in the same format that you will see when you take the certification exam. In this section you will find 150 sample questions, along with comprehensive answers for every question. (It's not enough to know which answer is correct; it's also important to know why the answer is correct and why the other choices are wrong!)...

This is the 3500 question test certificate B to refer your readers. They settled in the south-east of the island, became the majority and do a variety of languages other natives on the island, the Celts, come dangerously close to oblivion. English is widely used due to the influence of U.S. and UK in the fields of military, economic, science, computer science, politics and culture.

In international pistol shooting competition the performance improvement needed to be able to move into a medal winning position in a final from fourth position is 1.5 points (Bedford et al., 2012). It may be expected therefore, that by providing a method of reducing tremor resulting in a corresponding performance improvement. This research consists of two studies investigating the physiological response and the shooting performance of elite pistol shooters.

The objective of this project was to develop \(Ti{O_2}\) based multifunctional substrates through silver decoration, while simultaneously enhancing the photocatalytic performance of \(Ti{O_2}\) in the substrate. Employing Ag nanoparticles introduced additional functionality to the system, namely surface-enhanced Raman scattering (SERS), thus enabling the detection of trace amounts of organic molecules prior to their degradation, all with the same substrate.

The thesis is performed theoretically and experimentally. The theoretical studies on the dynamics of the single short pulse emission using transient cavity method and narrow linewidth and tunable wavelength generation using Littrow grating configuration were performed. On the other hand, the experimental investigations were carried out Experimental research was carried out based on the optimal results obtained by the theoretical studies.

The research in this thesis follows two directions: The first, using high performance computing currently available, we studied atomic and molecular emissions in astrophysical environment. The radiative transfer model was applied to explain the characteristics of the recombination line masers Hnα in the envelope of the star MWC 349A.
