The dual simplex method is frequently the most efficient technique for solving linear programming (LP) problems. This thesis describes an efficient implementation of the sequential dual simplex method and the design and development of two parallel dual simplex solvers. In serial, many advanced techniques for the (dual) simplex method are implemented, including sparse LU factorization, hyper-spa...

Abstract The topological Tverberg theorem states that any continuous map of a ‐simplex into the Euclidean ‐space maps some points from pairwise disjoint faces simplex to same point whenever is prime power. We substantially generalize this certain CW complexes, including simplicial ‐spheres, ‐space. also discuss atomicity property.

Poly-herbals combination was applied to enhance biological activity, particularly antioxidant activity. This present study purposed assess the synergistic interaction of a five traditional Indonesian herbal plants through simultaneous and integrated statistical technique. The were extracted using maceration, purification conducted before extraction eliminate ballast compounds. A simplex ...

Background : sunlight contains ultraviolet that happened skin problem from mild to severe. To overcome these problems, a sunscreen made natural materials is relatively safe. CKersen Leaves (Muntingia calabura L.) contain total flavonoids and phenolics can be used as active ingredients. In lotion preparations, emulsifiers affect the physical properties of lotions. Objective this research study o...

Muslim population in Indonesia reaches 87% and is one of the countries with largest muslim according to 2010 census. Thaharah things that Muslims pay much attention to, especially worship. One thaharah washing up from najis mughallazah. Soap skin cleansing preparations has become a public basic needs so innovation soap formulation containing bentonite as component can washed mughallazah make it...

Recent work in mathematical neuroscience has calculated the directed graph homology of simplicial complex given by brains sparse adjacency graph, so called connectome. These biological connectomes show an abundance both high-dimensional simplices and Betti-numbers all viable dimensions - contrast to Erd\H{o}s-R\'enyi-graphs comparable size density. An analysis synthetically trained reveals simi...
