We propose a practical method to construct sparse integer-constrained cone singularities with low distortion constraints for conformal parameterizations. Our solution for this combinatorial problem is a two-stage procedure that first enhances sparsity for generating an initialization and then optimizes to reduce the number of cones and the parameterization distortion. Central to the first stage is a progressive process to determine the combinatorial variables, i.e., numbers, locations, and angles of cones.

Computer simulations are used to assess the impact of thermal insulation on the transfer of heat and moisture in the exterior walls of residential buildings. The effects of internal and external thermal insulation on a room in a terraced family house are compared using the COMSOL Multiphysics software package, evaluating the influence of the placement of expanded polystyrene thermal insulation on the distribution of heat and moisture in the external wall while monitoring the indoor air temperature during the heating and cooling regimes.

Dependence of refractive index (RI) of seawater on salinity, temperature and wavelength n (S, T, λ) in infrared band is required.However, almost all the existing empirical formulas of the RI of seawater are suitable for the visible waveband (400 nm - 700 nm). There is little report on developing the RI expression of seawater in infrared band, especially the most commonly used 1200 nm - 1650 nm waveband.
