1. Artisanal boatbuilding in Brazilian shores: craftsmen, boatyards, and manufacturing process
Yuri Walter, Wilson Kindlein Junior, Tatiana Walter, Marielce de Cassia Ribeiro Tosta

The majority of Brazilian small craft fishing fleet comes from artisanal boatyards which struggles with market pressure, professional social devaluation, and lack of raw materials. This work aims to provide a description about small craft artisanal boatbuilding in Brazilian shores to support initiatives to increase its social, economical, and environmental sustainability. On site visits and interviews about craftsmen social-economics; boatyards' production organization; and manufacturing processes' technological aspects were conducted. Results show that craftsmen are characterized by reasonable income and livelihood degree, compared with workers of similar educational level in their region. Relationships and work organization among them is traditionally structured and community based. Boatyards have sufficient structure, though access to new technologies and resources could be increased. Observed plank on frame building technique depends on workforce skills, commitment, and knowledge, as well as the resulting boats' design and performance. Small craft artisanal boatbuilding is a living sector with its own dynamics, subjected to the creation and eventual adoption of new technologies. Instead of replacing the current manufacturing process by fibreglass reinforced polymer laminates, as suggested by some initiatives, it is believed that this sector's sustainability can be increased by gradual introduction of tools, materials, and techniques while preserving its artisanal characteristics and qualities.

Using suitable fibers and additives in concrete to enhance its performance is an important consideration in the concrete industry with regard to the structural aspects of concrete. The purpose of this project is to investigate numerically the effectiveness of the engineered steel fiber as shear reinforcement in RC beams. Here steel fibers completely replaces the shear reinforcement (stirrups & links). The dimension of beam taken was 1000*150*150 mm with aspect ratio 80. The beams were reinforced with 10 mm steel bars as secondary reinforcement and 12 mm bars as main reinforcement on the tension side. Numerical analysis using ANSYS R16.1 software package was carried out. The load-deflection curves for the beams with different dosage of fibers were drawn superimposing their numerical values. Initially, in all three cases the curve was linear elastic and about 80% of ultimate load they tend to be non-linear. It was observed that there was fair agreement between the results which indicates some favourable aspects concerning the use of steel fibres as shear reinforcement in concrete beams. It was investigated that the inclusion of steel fibres (Hook End Type) improves the shear strength of RC beams without stirrups by improving the matrix between concrete and steel fibers. Thus this project focuses in the design and analysis using the software ANSYS R16.1 for an alternative steel reinforcement with better or equivalent performance.

3. A Comparative Study of Various Methods to Evaluate Impedance Function for Shallow Foundations
Chandra Mohan and Samirsinh Parmar
International Journal of Advances in Engineering & Technology (IJAET), Volume 10 Issue 6, pp. 592-603, December 2017.
The dynamic response of rigid shallow foundations can be evaluated by impedance functions which is defined as a ratio between force or moment (input) versus displacement or rotation (steady state), (output) at the centroid of the base of massless foundation. The foundation vibration problems are described in six degrees of problems hence the impedance functions derived for translational modes. Stiffness and Radiation affects the dynamic soil-structure interaction as Impedance function is a function of stiffness as well as radiation damping. The present paper is comparative study of various methods like Barkan, Dominguez, Dobry and Gazetas for evaluation of impedance functions for various modes of vibration of shallow foundation. The pros and cons of the methods for estimation of impedance function was discussed. The stiffness in vertical direction shows similar trend for all four methods. The use of equivalent radius approach to compute dynamic stiffness and radiation damping causes large errors which leads wrong estimation of impedance functions.

4. Transient Analysis of Piezolaminated Composite Plates Using HSDT
P. Ravikanth Raju, J. Suresh Kumar
International Journal of Advances in Engineering & Technology (IJAET), Volume 10 Issue 6, pp. 604-612, December 2017.
Piezoelectric materials have excellent sensing and actuating capabilities have made them the most practical smart materials to integrate with laminated structures. Integrated structure system can be called a smart structure because of its ability to perform self-diagnosis and quick adaption to environment changes. An analytical procedure has been developed in the work based on higher order shear deformation theory subjected to electromechanical loading for investigating transient characteristics of smart material plates. For analysis two displacement models are to be considered i.e., model-1 accounts for strain in thickness direction is zero whereas in model-2 in-plane displacements are expanded as cubic functions of the thickness coordinate. Navier's technique has been adopted for obtaining solutions of anti-symmetric cross-ply and angle-ply laminates of both model-1 and model-2 with simply supported boundary conditions. For obtaining transient response of a laminated composite plate attached with piezoelectric layer Newmark's method has been used. Effect of thickness coordinate of composite laminated plates attached with piezoelectric layer subjected to electromechanical loadings is studied.

5. Active Safety Control Technique to Prevent Vehicle Crashing

International Journal of Advances in Engineering & Technology (IJAET), Volume 10 Issue 6, pp. 613-618, December 2017.
Alertness during driving is a key aspect. Even a small distraction for the driver may lead to genuine mishaps. The possible reasons can be obstacle, inadequate vehicle control system or human reflexes (e.g. shock) during sudden distraction. Therefore "active" and "passive" systems for vehicle control play a significant role in automotive safety. In this paper, we have discussed an active control technique to prevent the vehicle from crashing. Three different cases of vehicle speed are considered. The presented technique is designed to evaluate the possibility of collision for both front and rear side. The control action will be taken for safe and smooth driving under different situations like parking, urban driving and highway driving.
