The present production study shows that information structure is prosodically expressed in several parallel ways in Finnish. In addition to producing words in narrow focus with (1) a larger duration, (2) higher f0 peaks and greater falls, and (3) an earlier and more consistent peak alignment, participants frequently marked these words using also (4) pauses and (5) non-modal voice quality. Furth...
The geometry of a system of second order differential equations is the geometry of a semispray, which is a globally defined vector field on TM. The metrizability of a given semispray is of special importance. In this paper, the metric associated with the semispray S is applied in order to study some types of foliations on the tangent bundle which are compatible with SODE structure. Indeed, suff...
synthesis, identification and thermal behavior studies of nanoparticles cobalt (ii) bromide has been studied in this research. cobalt (ii) bromide was synthesized by planetary high-energy ball mill. the general formula of this compound is cobr2.6h2o. the synthesized nanoparticles were characterized by fourier transform infrared spectroscopy and also size and structure of synthesized nanoparticl...
Making varnishes from diterpenoid resins with the several orders had been common in Iran from 12th Century and it has also been reported in Europe from medieval ages. Identification of these resins in old samples and investigation of their degradations through ageing process have performed by various methods. FTIR spectrometry has always been of interest to researchers because it is cheap, avai...
A rigorous method is presented for the systematic identification of the structure and the parameters of transport coefficient models in three-dimensional, transient convection-diffusion systems using high resolution measurement data. The transport is represented by a convection term with known convective velocity and a diffusion term with an unknown, generally state-dependent, transport coeffic...
This paper presents a new recurrent neural network (RNN) structure called ENEM for dynamic system identification. ENEM structure is based on Elman network and NARX neural network. In order to show the performance of ENEM for system identification, the results were also compared to the results of Elman network, Jordan network and their modified models. The identification results of linear and no...
The Phomopsis is a genus of imperfect plant pathogenic fungus whose hosts comprise several species in different regions of the world, such as grapes, soybean, acacia, hollyhock, velvetleaf, and several other plants. In this study, samples collected from hollyhock, velvetleaf, purple bauhinia, and acacia plants suspected to be infected with Phomopsis fungi. Samples were culture...
The Existence of crack in a structure leads to local flexibility and changes the stiffness and dynamic behavior of the structure. The dynamic behavior of the cracked structure depends on the depth and the location of the crack. Hence, the changes in the dynamic behavior in the structure due to the crack can be used for identifying the location and depth of the crack. In this study the first th...
identification of the factors causing change in policy process plays an important role in implementing healthy policy process. narrative policy framework introduces new concepts and tools to identify the factors causing policy change. one of the important variables in narrative policy framework is narrative structure. narrative structure has so many elements which the main one is plot. plot lin...
the urgent need of neuraminidase inhibitors (ni) has provided an impetus for understanding the structure requisite at molecular level. our search for selective inhibitors of neuraminidase has led to the identification of pharmacophoric requirements at various positions around acyl thiourea pharmacophore. the main objective of present study is to develop selective ni, with least toxicity and dru...
