We introduced an analysis to identify structural characterization of two-dimensional regular and amorphous networks. The analysis was shown to be reliable to determine the global network rigidity and can also identify local floppy regions in the mixture of rigid and floppy regions. The eigenmode analysis explores the structural properties of various… (More)
A new fully secure ciphertext-policy attributed based encryption (CP-ABE) scheme with high expressibity access policy is presented. Our CP-ABE scheme uses tree-based access structure which includes AND, OR, threshold and NOT gates which granted high degree of expressibility for encryptor to make an access policy. Moreover, our scheme achieves full security… (More)
The numerical estimation of seismic isolation (SI) system with frictional bearing implies an exact solution of pertinent equations of motion. Rigid-perfectly plastic model is widely used technique to approximate the relationship of frictional force-displacement. This paper presents a direct treatment of equations of motion with prediction scheme for… (More)
This paper presents a new offset compensation method by modifying the previous two mode transition map method. Different from the previous method using the mode transition map, the proposed method employs fuzzy logic to smoothly change modes. This proposed method is verified through the computer simulations using Simulink based dynamic model.
—Terminal-based quality of Service (QoS) measurement method for the wireless internet services is proposed. Based on application interface method, which mechanism is sharing the service quality measurement data between the applications, we derive realistic system parameters such as average access time and throughput, and then propose a terminal-based… (More)
We calculate the local correlation functions of charge and spin for the one-chain and two-chain Hubbard model using the density matrix renormalization group method and the recursion technique. Keeping only finite number of states we get good accuracy for the low energy excitations. We study the charge and spin gaps, bandwidths and weights of the spectra for… (More)
