Background and Purpose: Abies cephalonica Loudon (Greek fir) is a dominant tree species of the mountainous Greece that forms productive forests. Wildfires in fir forests were not considered a major threat but in recent decades, fir ecosystems in Greece have experienced large crown fires with subsequent ecological and economical losses. Materials and Methods: This study was designed to aid our u...

Abstract—In Digital Signal Processing, one of the most important filter type is the FIR filter which can be designed via various methods. Window technique is the most important technique that is used to design the FIR filter. Apart from various window techniques, Dolph-Chebyshev window has the subject of importance for the design of the FIR filter in efficient way. In this paper, the design met...

Finite Impulse Response (FIR) filters are widely applied in multistandard wireless communications. The two key requirements of FIR filters are reconfigurability and low complexity. In this paper, two reconfigurable FIR filter architectures are proposed, namely Constant Shift Method [CSM] and Programmable Shift Method [PSM]. The complexity of linear phase FIR filters is dominated by the number o...

FIR filterbank precoders offer a unifying framework for several digital modulation and multiplexing schemes used in singleand multi-user transmissions, such as OFDM and CDMA. With minimal reduction in bandwidth efficiency, FIR filterbank transmitters can be designed to allow for perfect (in the absence of noise) equalization of any FIR channel with FIR zero-forcing (ZF) equalizer filterbanks. T...

Aim The conservation of biological and genetic diversity is a major goal of reserve systems at local, regional, and national levels. The International Union for the Conservation of Nature and Natural Resources suggests a 12% threshold (area basis) for adequate protection of biological and genetic diversity of a plant community. However, thresholds based on area may protect only a small portion ...

We developed a tissue culture incubator that can continuously irradiate cells with far-infrared radiation (FIR) of wavelengths between 4 and 20 microm with a peak of 7-12 microm, and found that FIR caused different inhibiting effects to five human cancer cell lines, namely A431 (vulva), HSC3 (tongue), Sa3 (gingiva), A549 (lung), and MCF7 (breast). Then, in order to make clear the control system...

The geometrical structures and photophysical properties of Ir(4,6-dFppy)₂(pic) (FIrpic) and its derivative (o-FIr, m-FIr, p-FIr) with dimethylamine substituted at the picolinic acid (N∧O) ligand were fully investigated by density functional theory and time-dependent density functional theory. The simulated electronic structure, as well as absorption and emission spectra of FIrpic are in good ag...
