Resumen
The concept of compliant axes is developed from the compliance matrix eigenvalue problem. It is shown that the necessary and sufficient conditions for the existence of a compliant axis are two collinear eigenscrews with eigenvalues of equal magnitude and opposite sign. This leads to a new classification of compliance matrices based on the number of compliant axes. Selected matrices from the literature illustrate both the compliant axis concept and the classification.

This article presents an approach for the compliance analysis and lightweight design of a two-degree-of-freedom rotating head by considering both gravity and joint/link compliances, which provides a comprehensive understanding on the posture adjustment mechanism of five-degree-of-freedom hybrid manipulator. A kinetostatic analysis is carried out to consider both externally applied wrench imposed upon the end-effector and gravity of all movable components. Then, a deflection analysis integrating both joint and link compliances and formulation of component compliance matrices are completed by us

Resumen
Spatial elastic behavior is characterized by a 6×6 positive definite matrix, the spatial stiffness matrix, or its inverse, the spatial compliance matrix. Previously, the structure of a spatial stiffness matrix and its realization using a parallel elastic system have been addressed. This paper extends those results to the analysis and realization of a spatial compliance matrix using a serial mechanism and identifies the duality in spatial stiffness and compliance associated with parallel and serial elastic mechanisms. We show that, a spatial compliance matrix can be decomposed into a set of ran

Resumen
This paper investigates the stiffness of a compliant planar parallel manipulator. Instead of establishing stiffness matrix directly for planar mechanisms, we adopt the modeling approach for spatial mechanisms, which allows us to derive two decoupled homogeneous matrices, corresponding to the translational and rotational stiffness. This is achieved by resorting to the generalized eigenvalue problem, through which the eigenscrew decomposition is implemented to yield six screw springs. The principal stiffnesses and their directions are then identified from the eigenvalue problem of the two separa

Resumen
Residual stress determination requirements of production and research users grow rapidly. Commercially available programs enable relatively quick residual stress evaluation with certain level of accuracy and with limited user access to used compliance matrices and calculations. However precise analyses require sensitive approach to compliance matrices determined for individual case e.g. for specific specimen dimensions. Therefore program tools for complex residual stress evaluation by Ring-Core method were developed using finite element analysis and Visual Basic scripts.

Resumen
This paper investigates the effect of strain gage length on residual stress estimated by the slitting (or crack compliance) method. This effect is quantified for a range of gage length normalized by sample thickness, l∕t, between 0.005 and 0.100. For specific l∕t values, compliance matrix elements are determined by finite element methods for a range of crack depth and polynomial basis functions for residual stress. Resulting compliance matrices are shown and used to determine error in residual stress that may arise due to differences in l∕t assumed in data reduction and existing in the slittin

The bond graph approach to modelling biochemical networks is extended to allow hierarchical construction of complex models from simpler components. This is made possible by representing the simpler components as thermodynamically open systems exchanging mass and energy via ports. A key feature of this approach is that the resultant models are robustly thermodynamically compliant: the thermodynamic compliance is not dependent on precise numerical values of parameters. Moreover, the models are reusable owing to the well-defined interface provided by the energy ports. To extract bond graph model

Of the total number of municipalities in the northern region of the State of Goiás, part of them have their own revenues below requirements, if current conditions are maintained, they tend to be incorporated into neighboring municipalities from 2025 onwards in compliance with PEC 188/2019.Would there be an alternative for municipal development and sustainability without the necessary population increase? In this sense, the purpose was to identify the economic and social weaknesses that characterize the municipalities in the northern region and to create a “Dependency Matrix”. The methodology c

Resumen
Introduction. When construction works are scheduled within the framework of a project that encompasses the construction of civil or industrial facilities representing a residential quarter, the focus is placed on the continuous operation of particular specialized construction departments, subject to the adherence to applicable technologies and compliance with standard deadlines that apply to the construction of buildings. The relevance of this problem stems from the complexity of coordination of works to be performed by contractors and subcontractors, involved in the development of a quarter a

Resumen
Linear modeling approaches for compliant mechanisms attract significant attention. However, geometrical nonlinearities require consideration generally because they may result in the modeling error. This paper presents a nonlinear quadrature beam element modeling approach for compliant mechanisms. The geometrically exact beam theory is employed as the basis for the element. Meanwhile, the element tangent stiffness matrix is obtained by using the weak form quadrature element method, which does not need shape functions any more and only performs simple algebraic operations of weighting coefficien

Resumen
Port State Control inspections play a paramount role in the enhancement of maritime safety. Port State Control regimes were established to ensure sustainability of Port State Control inspections. There are a total of 10 Port State Control regimes. Although all of these Port State Control regimes inspect foreign flag ships calling on their ports in compliance with international maritime safety and pollution regulations, still different implementations exist between these Port State Control regimes. According to the detentions, 73% of flag states have different performances in Port State Control

Resumen
A three-node six degree-of-freedom per-node line element that is sensitive to axial, bending, and torsional loading is introduced to model single-axis right circular hinges of constant width that are utilized in compliant mechanisms. The Timoshenko model is applied for bending because this particular configuration is virtually short, and provisions are taken that the element is shear-locking free. The Saint Venant theory, which includes warping, is utilized to model torsion of the variable rectangular cross-section circular hinge. The principle of minimum total potential energy is employed to

Resumen
Bioanalysis is the scientific field of the quantitative determination of xenobiotics (e.g., drugs and their metabolites) and biotics (e.g., macromolecules) in biological matrices. The most common samples in bioanalysis include blood (i.e., serum, plasma and whole blood) and urine. However, the analysis of alternative biosamples, such as hair and nails are gaining more and more attention. The main limitations for the determination of small organic compounds in biological samples is their low concentration in these matrices, in combination with the sample complexity. Therefore, a sample preparat

Resumen
Abstract Background: Afidopyropen is a recently introduced insecticide that provides effective control of insect pests in vegetable crops, including brinjal. Field applications of this insecticide can often result in accumulation of residues in brinjal fruits, leaves, and soil at harvest, which might be a concern for food and environmental safety. This demands an appropriate method for analysis of the residues of this insecticide in these matrices to facilitate residue monitoring and safety compliance checks.

Resumen
The paper presents a vector algebraic method for the displacement and force analysis of the five-rod wheel suspension mechanism, used as a rear suspension in some modern cars. Displacement equations are derived by using the solutions of the vector tetrahedron equations obtained as the closure or constraint equations for spatial multi-loop mechanisms. The method gives the possibility of reducing the system of constraint equations from the original five to two. The resultant equations are expressed in recursive notation, which isrelatively concise in form and convenient for programming, providin
