The "determining modes" concept introduced by Foias and Prodi in 1967 say that if two solutions agree asymptotically in their P projection, then they are asymptotical in their entirety. In this paper, we consider the 2D g-Bénard problem in domains satisfying the Poincaré inequality with homogeneous Dirichlet boundary conditions.

The extensive use of petroleum–based synthetic plastics is leading to various environmental problems such as ecological impact, and untreated plastic waste, particularly micro–plastic pollution. Bioplastics are, therefore, considered one of the prospective solutions to replace conventional plastics.

In this report, we examine the unsteady Stokes equations with nonhomogeneous boundary conditions. As an application of a Carleman estimate, we first establish log type stabilities for the solution of the equations from either an interior measurement of the velocity, or a boundary observation depending on the trace of the velocity and of the Cauchy stress tensor measurements on a part of the boundary.

A hybrid analytical-numerical solution is proposed to solve the problem of a laterally loaded pile with a circular cross-section in multilayered soils. In the pile-soil model, the lateral load is located at the pile head including both lateral force and bending moment. The single pile is considered as a beam on elastic foundation while shear beams model the soil column below the pile toe.

The research objects are the Law on Enterprise Income Tax, the Law on Value-Added Tax, decrees and circulars guiding these laws. The methods used in this study are: Desk Research and Theoretical Research. Results of this study show that the legal framework of tax incentives for startups is incomplete. Besides, results of this study also show that the legal framework of tax incentives for startups still faces many limitations and problems, which requires the need to complete the law.

In addition, we also show that our present solutions are valid for the problems of indentation by a rigid punch on an elastic half-space through a proper replacement of the contact radius and the corresponding material constant. Numerical results are provided to demonstrate the accuracy, applicability, and versatility of the developed solutions.

The dynamic analysis is a necessity in the design, manufacturing and maintenance of structures. The analytic solutions are not available for most practical cases and the Finite Element Method (FEM) is not reliable due to the joint problem, unclear loading, material properties and numerical error. In this paper, we present a way to find modes shape of 3D Frame by FEM program using Matlab.

This thesis proposes and implements a new and novel solution on simulators and real devices to solve the mobility problem in a VPN. The new solution adds mobility support to existing L2TP/IPsec (Layer 2 Tunneling Protocol/IP Security) tunnels. The new solution tunnels Layer 2 packets between VPN clients and a VPN server without using Mobile IP, without incurring tunnel-re-establishment at handoff, without losing packets during handoff, achieves better security than current mobility solutions for VPN, and supports fast handoff in IPv4 networks.

Organizations have long struggled with the successful completion of projects within the time, cost and performance indicators with respect to a customer product or solution that is expected to ultimately meet the customer’s expectations. This thesis demonstrates the link between the successful creation, management and dissemination of project requirements throughout the entire project process using a knowledge management overlay model to ensure the success of the overall project to meet stakeholder needs through the successful creation and transfer of project requirements.

In the work "Master's thesis of Science: User delay tolerance - aware edge node placement optimization for cost minimization", we review the related works and identify the research gaps in Chapter 2. Then, we formulate our problem in Chapter 3 and prove the NP-hardness of the problem in Chapter 4. Base on our problem formulation, we provide a suit of solutions in Chapter 5. After that, we do an comprehensive evaluation on our proposed methods in Chapter 6. Finally, we summarise our work in Chapter 7.

This paper suggests a solution for the image segmentation (IS) problem with the multilevel thresholding based on one of the latest hybrid swarm computation optimization algorithms, particle swarms, and gravitational search (PSGA). The experimental results are comparable with other state-of-the-art algorithms that show that the PSGA on selected images is better than the competitors.
