in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
Aims & Backgrounds: The traditional spaces of the vernacular houses have been neglected in architectural and urban designs due to globalization policies and modernizing urban models, so it is necessary to review and classify their efficiency again in the reconstruction and the design of new villages to strengthen the vernacular identity of villages and to consider it in their physical developme...
until now many studies have been done over recent decades throughout the world to show the right age to start english. in iran, research is still at an early stage in terms of evaluating teachers’ beliefs about teaching children english. the problem of at what age to start teaching english and how to teach english to elementary school children has not been solved neither in this country nor els...
Magnetic Resonance Imaging (MRI) is a noninvasive imaging method widely used in medical diagnosis. Data in MRI are obtained line-by-line within the K-space, where there are usually a great number of such lines. For this reason, magnetic resonance imaging is slow. MRI can be accelerated through several methods such as parallel imaging and compressed sensing, where a fraction of the K-space lines...
in this paper, we introduce λκ−closed sets and study its properties in generalized topological spaces.
we have devided the thesis in to five chapters. the first recollects facts from purely algebraic theory of jordan algebras and also basic properties of jb and jb* - algebras which are needed in the sequel. in the second chapter we extend to jb* - algebras, a classical result due to cleveland [8]. this result shows shows the weakness of jb* - norm topology on a jb* - algebera. in chapter three, ...
WLAN-based location systems are implemented in indoor location service in recent years. These systems suffer largely from the signal disturbance under open WLAN environment, which introduces decrease in accuracy and stability of the location service. This paper presents a new algorithm, which utilizes multi-space projections of radio space on sub-level signal spaces to mitigate the influence fr...
Let ? be an open connected subset of the complex plane C and let T be a bounded linear operator on a Hilbert space H. For ? in ? let e the orthogonal projection onto the null-space of T-?I . We discuss the necessary and sufficient conditions for the map ?? to b e continuous on ?. A generalized Gram- Schmidt process is also given.
This paper intends to highlight one of the key concerns of housing designers i.e. the influence of open space on human satisfaction as well as their attachment to a particular place. Consequently, neighborhood open spaces with their meaningful layout seem to be constituent elements of residential complexes. Although, architects and designers try to create qualitative areas among buildings, the ...
increasing academic and professional language demands around the world are not a deniable fact. the purpose of this study was to investigate english language needs and communication needs of the chemistry students at master and ph.d. levels at the iranian universities. in this research, different methods were used including un-structured interview, structured interview, and two sets of question...
