In this paper, we introduce a new dedicated 256-bit hash function: NESHA-256. The recently contest for hash functions held by NIST, motivates us to design the new hash function which has a parallel structure. Advantages of parallel structures and also using some ideas from the designing procedure of block-cipher-based hash functions strengthen our proposed(More)
The goal of sparse linear hyperspectral unmixing is to determine a scanty subset of spectral signatures of materials contained in each mixed pixel and to estimate their fractional abundances. This turns into an 0-norm minimization, which is an NP-hard problem. In this paper, we propose a new iterative method, which starts as an 1-norm optimization that is(More)
