Summary: The proposed scalable high-radix Montgomery Modular Multiplication circuit utilizes carry-save compressions to eliminate costly multiplications in the Montgomery MM algorithm. It achieves a scalable design by decomposing the multiplicand itself using a radix of 2(w) and offers an issue latency of one cycle. The area complexity is O(wmp), resulting in an Area-Latency-Product complexity of O(N-2).

Summary: It is well established that large temperature gradients cause strong textures in metal parts manufactured via laser beam powder bed fusion, resulting in anisotropic mechanical behavior. This study compared two different modeling techniques for predicting mechanical properties, and found that the model based on equally weighted crystallographic orientations accurately predicted macroscopic properties while reducing computational cost.

Summary: The fracture toughness properties of additively manufactured AlSi10Mg were computationally explored in this study. The investigation involved finite element analysis of a previous experimental work using critical crack opening displacement (COD), stationary crack method, and extended finite element method (XFEM). Load-displacement curves were simulated for each build case using COD method, and the knife-edge displacements from the COD models were used to simulate J resistance behavior. The J curves captured the anisotropy due to varying build conditions, and the fracture toughness values correlated well with experimental results. XFEM models were also created at both specimen scale and meso-scale, successfully predicting crack path and improving understanding of crack propagation behavior.
