1. Enabling design characteristics and budget usefulness
Abstract Purpose This study aims to investigate the influence of budgeting design characteristics on perceived budgeting usefulness, based on the enabling-coercive framework. Design/methodology/approach This paper develops a survey in one large publicly-listed Brazilian company that operates in the electric utility industry. The sample comprises 75 middle

2. Structural reliability analysis of steel plane frames with semi-rigid connections
Abstract The design codes for structural design traditionally establish the adoption of partial safety factors to deal with uncertainties. These standards do not allow one to know the real probabilities of failure of a structure. What is needed, from a practical and scientific point of view, is a more consistent approach, based on reliability theory. This ar

3. Optimum Design of Effective Parameters for Orthotropic Plates with Polygonal Cut-Out
Abstract This paper investigates the effect of different parameters on stress analysis of infinite orthotropic plates with central polygonal cutout using gray wolf optimization algorithm. The important features of gray wolf algorithm include flexibility, simplicity, short solution time and ability to avoid local optimums. The effective parameters on stress d

4. Stability Analysis of Variable Stiffness Composite Laminated Plates with Delamination Using Spline-FSM
Abstract The dynamic behavior of variable stiffness composite laminated (VSCL) plate with curvilinear fiber orientation subjected to in-plane end-loads is investigated. A variable stiffness design can increase the laminated composite structural performance and also provides flexibility for trading-offs between various structural properties. In each ply of th

5. Dynamic Response of Dam-Reservoir Systems: Review and a Semi-Analytical Proposal
Abstract This paper presents a review of current techniques employed for dynamic analysis of concrete gravity dams under seismic action. Traditional procedures applied in design bureaus, such as the Pseudo-Static method, often neglect structural dynamic properties, as well as ground amplification effects. A practical alternative arises with the Pseudo-Dynami

6. Concept of a Maneuvering Load Control System and Effect on the Fatigue Life Extension
Abstract This paper presents a methodology for the conceptual design of a Maneuver Load Control system taking into account the airframe flexibility. The system, when switched on, is able to minimize the bending moment augmentation at a wing station near the wing root during an unsteady longitudinal maneuver. The reduction of the incremental wing bending mome

7. Study of the structural, thermal, rheological and film properties of functional copolymers of hydroxyethyl acrylate and methyl methacrylate
Abstract New functional polymers will be prepared using alkyd resins having high solid content (environmentally friendly) and comb-type structural morphology. Different copolymers of hydroxyethyl acrylate and methyl methacrylate (HEMMA) were synthesized by solution polymerization using azo-bis-(isobutyronitrile) (AIBN) as initiator and dimethylformamide as a

8. Construction of a Morphing Wing Rib Actuated by a NiTi Wire
ABSTRACT: The main goal of this paper is to analyze if it is feasible to employ a trained shape memory alloy wire as a linear actuator to modify the camber of a morphing wing rib. In order to achieve this purpose, a morphing rib with a compliant trailing edge was proposed, developed, and subjected to structural analyses to ensure its flexibility. After the r

9. Dynamics of rotating non-linear thin-walled composite beams: analysis of modeling uncertainties
In this article a non-linear model for dynamic analysis of rotating thin-walled composite beams is introduced. The theory is deduced in the context of classic variational principles and the finite element method is employed to discretize and furnish a numerical approximation to the motion equations. The model considers shear flexibility as well as non-linear

11. Poly(L-co-D,L lactic acid-co-trimethylene carbonate) scaffolds for growth of osteoblastic cells (SaOS-2) / Arcabouços de poli(L-co-D,L ácido láctico-co-trimetileno carbonato) para o crescimento de células osteoblásticas (SaOS-2)
Lactic acid based polymers are widely investigated as materials for tissue engineering. The ability to allow hydrolytic degradation, to be reabsorbed by the body and its inherent biocompatibility, make them an excellent choice for this application. However, characteristics such as low flexibility and low elongation ability before the fracture tend to limit t

12. Modelagem em geometria digital aprimorada por técnicas adaptativas de segmentos de retas. / Digital geometry modelling enhancement by straight line segment adaptive techniques.
For the representation of digital straight lines, digitized straight line segments and arcs, each of the available research approaches has its advantages and suitable applications. However, taking into account the complexities of real-world scenarios, the use of these representations is not so popular in situations that require flexible models or involving s
