Mechanical design

In kinematic synthesis and analysis of planar mechanisms the designer must define a geometry and set of motions for a design task. This paper will focus on how to determine the forces or torques acting on the planar mechanism by numerical method when acceleration and dynamic properties of the linkage are known.

In this paper, we propose a novel DL-based solution for web attack detection, named DL-WAD, leveraging deep learning and natural language processing techniques. Moreover, DL-WAD is designed with a data preprocessing mechanism aimed at differentiating between regular web requests and malicious ones that carry attack payloads encompassing multiple types of web attacks.

This paper presents a procedure to design cellular composite beams according to EN 1994-1-1. In addition, a parametric study is carried out to evaluate the influence of circular opening geometry to ultimate load and failure mode of a series of cellular composite beams. As a result, an optimal dimension of cellular beam is proposed.

This research has raised the question of whether the vibration transmission at a wall junction depends on how the wall is excited (by either a sound wave or a mechanical shaker). The aim of this research is to investigate this question and hence contribute to the revision of the series of standards. Villot and Guigou-Carter (2000) have considered this problem but their equations (10) and (13) appear to be in error. This research will endeavour to derive the correct equations and r epeat Villot and Guigou Carter’s calculations.

3D animation software is extensively used to create graphics for special effects sequences in live-action films, in animated feature film production and for the generation of computer games and virtual reality content. It is a commonly held view within the computer graphics community that 3D animation software is ―just another tool‖ for self-expression. This research questions that view by examining the inherent nature of the tool itself. In doing so, some of the philosophical assumptions embedded in the design of the new digital tool are revealed.

The aim of the work "Stochastic service life prediction of RC girders subjected to chloride induced corrosion – Shear limit state" presented in this thesis is service life prediction of corroded reinforced concrete girders, which forms an important part of durability design. The scope of this work is limited to shear limit state considering the chloride induced corrosion of reinforcement as the degradation mechanism. The review of literature shows that the service life estimation of reinforced concrete bridges exposed to marine environment is an active area of research.

Thermostable and highly water-soluble polymers are essential for polymer flooding — one of the most effective methods used in the enhanced oil recovery (EOR) in hightemperature (HT) offshore reservoirs. In this research, the copolymerization reaction of acrylamide (AM) and N-vinylpyrrolidone (NVP) monomers were performed via a freeradical mechanism induced by gamma-rays (γ-rays) irradiation.

This work presents results from a numerical investigation on the influence of fluid-structure interaction (FSI) on the dynamic response of thin steel plates subjected to blast loading. The loading was generated by a shock tube test facility designed to expose structures to blast-like loading conditions. The steel plates had an exposed area of 0.3 m × 0.3 m and experienced large deformations during the tests.

In Vietnam, lotus plants are widely grown. Some parts of the lotus plant have been used as a tradition medicine. The lotus plant is easy to find, inexpensive, non-toxic and accepted by many Vietnamese people as a means of treating diabetes, and yet data on the mechanism or even effectiveness of lotus leaf on diabetes mellitus was not known. The present study was designed to evaluate the hypoglycemic effect of lotus leaf on mice which had alloxan induced diabetes.
