1. THE USE OF THE AUTOMATED DIGITAL ZENITH CAMERA SYSTEM IN ISTANBUL FOR THE DETERMINATION OF ASTROGEODETIC VERTICAL DEFLECTION
Abstract: The Digital Zenith Camera Systems (DZCSs) are dedicated astrogeodetic instruments used to obtain highly accurate astrogeodetic vertical deflection (VD) data. The first Turkish DZCS, the Astrogeodetic Camera System (ACSYS), was developed in Istanbul, Turkey in 2015. The ACSYS was capable of determining astrogeodetic VDs with an accuracy of ~0.3 arcs

2. Flexural behavior of hybrid GFRP - concrete railway sleepers
Resumo Este trabalho tem por objetivo apresentar o comportamento à flexão de vigas híbridas de GFRP (glass fiber reinforced polymer - polímero reforçado com fibra de vidro) e concreto para aplicação em dormentes ferroviários. Pretendeu-se obter dormentes com adequada resistência mecânica, não susceptíveis à corrosão, duráveis e mais leves que

4. Hankel transformation method for solving the Westergaard problem for point, line and distributed loads on elastic half-space
Abstract The Hankel transformation method was used in this work to determine the normal and shear stress distributions due to point, line and distributed loads applied to the surface of an elastic media. The elastic media considered in this study was assumed to be inextensible in the horizontal directions, and the only non-vanishing displacement component is

5. Investigating the Influence of Auxiliary Rails on Dynamic Behavior of Railway Transition Zone by a 3D Train-Track Interaction Model
Abstract Abrupt track vertical stiffness variations along railway tracks can lead to increased dynamic loads, asymmetric deformations, damaged track components, and consequently, increased maintenance costs. The junction of slab track and ballasted track is one of the existing areas where vertical track stiffness can suddenly change, therefore requiring a tr

6. Effects of Key Factors on Hull Girder Ultimate Strength Estimation by Progressive Collapse Calculations
Abstract The estimation of the ship hull girder ultimate strength under vertical bending moments as close to real behavior is vital both for design stage or seagoing life. The maximum load carrying capacity of ship hulls called ultimate strength depends on a number of factors including the strength of the structural material, initial distortions, dimensions

7. A New Jacobi-based Iterative Method for the Classical Analysis of Structures
Abstract Traditionally, classical methods of structural analysis such as slope-deflection and moment distribution methods (Cross method) are used for primary analysis of structures and also controlling the results of computer programs. The main objective of this paper is to introduce a new method for classical computing and extending it to a matrix formulati

8. Optimal design of passenger car suspension for ride and road holding
The primary function of a vehicle suspension system is to isolate the road excitations experienced by the tyres from being transmitted to the passengers. In this paper, a suitable optimizing technique is applied at design stage to obtain the suspension parameters of a passive suspension and active suspension for a passenger car which satisfies the performanc

9. Determinação do desvio da vertical empregando observáveis da topografia clássica e do posicionamento por satélites / Determinação do desvio da vertical empregando observáveis da topografia clássica e do posicionamento por satélites
Esta dissertação apresenta uma proposta metodológica para obtenção do desvio da vertical. Os métodos convencionais de determinação do desvio da vertical utilizam as laboriosas observações astronômicas. A metodologia aqui proposta emprega as observáveis da topografia clássica e dos sistemas de posicionamento por satélites. O princípio do métod

10. Análise experimental de vigas pré-formadas de concreto armado à flexão e ao cisalhamento / Experimental analysis of reinforced concrete preformed beams to bending and shear
Reinforced concrete preformed beams are structural elements which present a thin superficial precast concrete layer that defines their geometrical shapes. This superficial layer functions as a formwork that will be incorporated to the beam after the introduction of cast in loco concrete, which will consolidate the structure. This construction system presents

11. FUNDAMENTAL CONCEPTS OF GRAVIMETRIC GEOID DETERMINATION / FUNDAMENTOS CONCEITUAIS DA DETERMINAÇÃO DO GEÓIDE PELO MÉTODO GRAVIMÉTRICO
Fundamentos conceituais da determinação do geóide pelo método gravimétrico com o objetivo de ordenação didática. Mostra-se que o estudo da Terra real possui um grande número de variáveis, o que torna a solução do problema inviável. Estuda-se então, o comportamento da Terra real por meio da determinação de parâmetros da Terra normal. Utiliza-

12. Influence of wood pallets in the behavior of drive-in racks with one level of loading / Influencia dos paletes de madeira no comportamento das estruturas de armazenagem do tipo drive-in com um nivel de carregamento
This dissertation?s intent is to investigate experimentally the influence the wood pallets exert on the behavior of the drive in storage racks with one level of loading. To consider the pallets as roller supported on both rails of the structure implies in not to consider the influence of the friction between the pallets and the rails in the behavior of the s
