Measurement of acoustic glitches in solar-type stars from oscillation frequencies observed by Kepler
A. Mazumdar, M. J. P. F. G. Monteiro, J. Ballot +15
For the very best and brightest asteroseismic solar-type targets observed by Kepler, the frequency precision is sufficient to determine the acoustic depths of the surface convectiv…
A new procedure for defining a homogenous line-list for solar-type stars
S. G. Sousa, N. C. Santos, V. Adibekyan +9
Context. The homogenization of the stellar parameters is an important goal for large observational spectroscopic surveys, but it is very difficult to achieve it because of the dive…
Supersonic flutter analysis of flat composite panels by unified formulation
S Natarajan, G Manickam, AJM Ferreira +1
In this paper, the linear flutter characteristics of laminated composite flat panels immersed in a supersonic flow is investigated using field consistent elements within the framew…
Static bending and free vibration of cross ply laminated composite plates using NURBS based finite element method and unified formulation
S Natarajan, H Nguyen-Xuan, AJM Ferreira +1
This paper presents an effective formulation to study the response of laminated composites based on isogeometric approach (IGA) and Carrera unified formulation (CUF). The IGA utili…
Multiple-choice Vector Bin Packing: Arc-flow Formulation with Graph Compression
Filipe Brandão, João Pedro Pedroso
The vector bin packing problem (VBP) is a generalization of bin packing with multiple constraints. In this problem we are required to pack items, represented by p-dimensional vecto…
New inversion, convolution and Titchmarsh's theorems for the half-Hilbert transform
Semyon Yakubovich
While exploiting the generalized Parseval equality for the Mellin transform, we derive the reciprocal inverse operator in the weighted L_2-space related to the Hilbert transform on…
