block ciphers have wide applications for hardware and software implementations. in this paper, a new block cipher algorithm with provable security is proposed. the whole structure of the algorithm is novel and has a good encryption and decryption performance. additionally, it has good security with few number of rounds. the structure of the proposed algorithm consists of 4-rounds feistel-like w...

A closed-form limit on the input level of the double impulse as a substitute of a near-fault ground motion is derived for the overturning of a rigid block. The rocking vibration of the rigid block is formulated by using the conservation law of angular momentum and the conservation law of mechanical energy. The initial rotational velocity after the first impulse and the rotational velocity after...

A generalisation of modularity, called block is defined. This a quality function which evaluates label assignment against an arbitrary pattern. Therefore, unlike standard modularity or its variants, network structures can be compared and optimal matrix determined. Some simple algorithms for optimising are described applied on networks with planted structure. In many cases the structure recovere...

This talks examines the effect of angular ordering on the small-x evolution of the unintegrated gluon distribution, and discusses the characteristic function for the CCFM equation. For some time now it has been known that angular ordering [1] is an essential element in any description of small-x final state properties [2]. As a first step of a programme to study the final state in small-x physi...

In the title compound, tetra-hydro-seselin, C14H16O3, a pyran-ocoumarin [systematic name: 8,8-dimethyl-3,4,9,10-tetra-hydro-2H,8H-pyrano[2,3-f]chromen-2-one] obtained from the hydrogenation of seselin in the presence of Pd/C in MeOH at room temperature, the dihedral angle between the central benzene ring and the best planes of the outer fused ring systems are 6.20 (7) and 10.02 (8)°. In the cry...

In this paper, we propose an algorithm of angular mode selection for high-performance HEVC intra prediction. HEVC intra prediction is used to remove the spatial redundancy. Intra prediction has a total of 35 modes and block size of 64x64 to 4x4. Intra prediction has a high amount of calculation and operational time due to performing all 35 modes for each block size for the best cost. The angula...
