most of the researches do not differentiate between intuitive critic and passive one – in the field of features, applications and methods. this critical school is called emotional or passive critics which emphasizes aesthetics. thus sensitivity is not the only appliance to wisdom but is a mean to inspire happiness or unhappiness feeling. consequently the passive (critical) school is the result ...
gamma camera is an important apparatus in nuclear medicine imaging. its detection part is consists of a scintillation detector with aheavy collimator. substitution of semiconductor detectors instead of scintillator in these cameras has been effectively studied. in this study, it is aimed to introduce a new design of p-n semiconductor detector array for nuclear medicine imaging. a p-n semiconduc...
in this work the performance of a wavelength division multiple access (wdma) system with direct detection receiver is investigated. for this purpose, the probability of error in a wdma network with ook modulation considering crosstalk, isi, photo detector noise and thermal noise is calculated and the effect of each on system performance is investigated. the system performance in presence of pin...
background: estimating dosimetric parameters for small fields under non-reference conditions leads to significant errors if done based on conventional protocols used for large fields in reference conditions. hence, further correction factors have been introduced to take into account the influence of spectral quality changes when various detectors are used in non-reference conditions at differen...
The radiation hardness of passive CMOS pixel sensors fabricated in 150 nm LFoundry technology is investigated. process lines are especially interest for large-scale silicon detectors as they offer high production throughput at comparatively low cost. Moreover, several features like poly-silicon resistors, MIM-capacitors and metal layers available which can help enhance the sensor design. perfor...
The objective of this research was to improve 3-D imaging system by near-infrared light emission in breast tissue to achieve a more accurate diagnosis of tumor. The results of repeated experiments in this research have shown that with this imaging system, a more accurate diagnosis of abnormal area depends on the location of the sources and detectors. Therefore, an optimal location model has bee...
Abstract This paper reports a review on the relationship between seismic activity and emissions of CO 2 radon. Direct, indirect sampling methods are mainly employed to measure flux concentration in areas. The accumulation chamber technique is mostly used literature. Radon gas emission areas can be considered as short-term pre-seismic precursor. study measurement radon prior earthquakes performe...
Legate (2003) argues, contra Chomsky 2001, that passive vP is a phase in English. In this paper, I present novel Bosnian/Croatian/Serbian (BCS) data from (i) theme vowel quality, (ii) apparent non-local allomorphy and allosemy, (iii) agreement to support the claim not phasal language. Comparing these findings with Legate’s, show those of her diagnostics can be applied BCS put participles on par...
Background & Objective: The present research project is based on the common ground in nuclear and medicine science. The purpose is to determine the concentration of radon gas in residential homes in Fasa in 1395 for investigating the effects of its inhalation on the incidence of lung cancer in residents of the home. Material & Methods: Among the residential houses, 10 houses were selected in di...
