NUMERICAL SOLUTION OF 2-D EULER EQUATIONS WITH MULTIGRID
Havacılık ve Uzay Teknolojileri Dergisi, 2007 A multigrid scheme is applied to accelerate the convergence of numerical solution of two dimensional Euler equations to steady state. Cell-centered finite volume method with central differencing scheme is used for discretization. Explicit multistage time-

Computer Graphics Forum, EarlyView.Abstract We introduce mixed super‐circles, a position‐curvature formulation of the original dynamic 2D super‐helix model. Compared to the latter, purely curvature‐based model – the so‐called chained formulation –, the mixed formulation that we propose here drastically reduces the algorithmic complexity of the solving scheme – from quadratic to quasi ...

Fast Nodal Hessian Computation for Peridynamic Fracture Simulation
Computer Graphics Forum, EarlyView.A fast, exact nodal Hessian computation for Non‐Ordinary State‐Based Peridynamics is introduced through analytical simplification and a warp‐centric GPU strategy. The method accelerates preconditioned solvers and Vertex Block Descent, enabling interactive fracture simulation with physical accuracy.

Advances in 4D Representation: Geometry, Motion, and Interaction
Computer Graphics Forum, EarlyView.We survey 4D representation through three key pillars — geometry, motion, and interaction — offering a selective, representation‐centric perspective to guide researchers in choosing and customizing the right 4D representation for their tasks. Abstract We present a survey on 4D generation and reconstruction, a fast‐evolving subfield of computer graphics

Life Cycle Consumption and Portfolio Choice Under Real Interest Rate Risk
Financial Management, EarlyView.ABSTRACT We set up a life cycle model with real interest rate risk to demonstrate that real interest rates have implications for optimal household consumption and investments. Lower interest rates lead to higher optimal stock investments and lower consumption.

How Does Progressivity Affect the Tax Cut Multiplier?
International Economic Review, EarlyView.ABSTRACT How does the targeting of personal income tax cuts affect the output multiplier? This paper provides quantitative evidence using a heterogeneous‐agent New‐Keynesian model calibrated to match US distributions of income, wealth, marginal tax rates, and marginal propensities to consume.

Monetary and Macroprudential Policies under Dollar‐Denominated Foreign Debt
Journal of Money, Credit and Banking, EarlyView.Abstract This paper studies monetary and macroprudential policies in a small open economy that borrows from abroad in foreign currency. The model features a novel mechanism in which exchange rate depreciation triggered by a borrowing constraint is amplified through balance of payments adjustments, increasing the real burden of foreign debt and causing ...

Journal of Microscopy, EarlyView.Abstract Transmission Kikuchi diffraction in the scanning electron microscope has gained popularity as a materials characterisation technique for its high throughput and nanometre‐level spatial resolution. While conventional diffraction pattern analysis routines focus on Kikuchi bands on the diffraction patterns, the full physical picture of electron ...
