In this paper design of low pass optimal block digital filter is compared with traditional low pass overlap-save block digital filter. Simulation results show that global error obtained by optimal method is lower than that obtained by traditional overlap-save method. Index Terms Block digital filters, optimum design, overlap-save method, frobenius norm, aliasing, time-varying system.

Aims Micro-CT is an established tool to evaluate the bone architecture in small animals. Especially in-vivo micro-CT is very popular, as it allows longitudinal (i.e. over time) follow-up of the evolution in the same animal. This way, changes in the bone structure over time can be assessed. Usually, bone parameters are measured separately in the different images. To be comparable, a similar loca...

The mixed crystal Rb~ —„(NH4)„HzAs04 (RADA) has been investigated for several values of x(x =0, 0.12, 0.15, and 0.20) by measuring the complex dielectric permittivity along the a tetragonal axis in the temperature range from 3 to 300 K and frequency range from 1 Hz to 30 kHz. We find coexistence of ferroelectric and proton-glass order in RADA for x =0.12 and probably at x 0.15. The long-range f...

We discuss the scaling behaviour of different fermion actions in dynamical simulations of the 2-dimensional massive Schwinger model. We have chosen Wilson, hypercube, twisted mass and overlap fermion actions. As physical observables, the pion mass and the scalar condensate are computed for the above mentioned actions at a number of coupling values and fermion masses. We also discuss possibiliti...

In this paper, first we identify the destruction ways of concrete constructions and the benefits of waste management and the plans to recycle the concrete debris were investigated and it was concluded that the existence of plans to recycle the concrete debris could lead to big economic save ups and by recycling these debris we can create affordable ways for concrete making centers. By the way, ...

In this communication we have summarized and in some details extended the publications on this subject which have appeared in the Japanese literature. 1 In the course of our investigations of that endemic disease of portions of Japan, which agrees clinically with Well's disease, so called, we discovered a spiroch~etal microorganism which is now believed to be the cause of the disease. In the ex...

An important, yet minimally explored, aspect of emotion simulation is the way in which changes in emotion eliciting situations can give rise to different intensities in the resulting emotion instances. Usin~ the work of Ortony, etal. [Ortony e~ al., 1988J as a guide, we propose a set of emotion inLe~siLy ~ariables to be used in modeling the causes of varying emotion intensity, and discuss their...
