Background In the framework of network sampling, random walk (RW) based estimation techniques provide many pragmatic solutions while uncovering the unknown network as little as possible. Despite several theoretical advances in this area, RW based sampling techniques usually make a strong assumption that the samples are in stationary regime, and hence are impelled to leave out the samples collec...

We propose a semi-automatic method to regenerate simplified vocal tract geometries from very detailed input (e.g. MRI-based geometry) with the possibility to control the level of detail, while maintaining the overall properties. The simplification procedure controls the number and organization of the vertices in the vocal tract surface mesh and can be assigned to replace complex cross-sections ...

In this paper, we study parametric nonlinear regression under the Harris recurrent Markov chain framework. We first consider the nonlinear least squares estimators of the parameters in the homoskedastic case, and establish asymptotic theory for the proposed estimators. Our results show that the convergence rates for the estimators rely not only on the properties of the nonlinear regression func...

vibration generated by vehicles during road transport has an important effect on the agricultural products damage process, particularly vegetable and fruit. modulus of elasticity is one of the most important mechanical properties of fruits and its variation can be described as one of the damage criteria during transportation. this research was conducted to evaluate the effects of vibration para...

narrative frequency is one of the main temporal and stylistic categories as well as an important miraculous aspect de-familiarizing qur’an. the story of adam is among the qur’anic stories that have been repeated in seven verses. of the artistic aspects of this story, it can be referred to its narrative dissemination. the types of frequency differing from singular, anaphoric, style and anaphoric...

This paper reports the fabrication of solid-state nanofiber sensor arrays and their use for detection of multiple proteins using principal component analysis (PCA). Four cationic and anionic fluorescently embedded nanofibers are generated by an electrospinning method, yielding unique patterns of fluorescence change upon interaction with protein samples. Five metal and nonmetal containing protei...

Following previous tests done on chemically regenerable carbon, Norit has developed a new grade of carbon that has faster adsorption kinetics. The effect of repeated cycles and chemical regenerations on the colour removal performance of this carbon has been investigated. Decolourisation trials were performed on brown liquor with a pilot plant supplied by Norit at the SMRI. Tests were carried ou...

Since the late 1980s most of the countries in Central and Eastern Europe have been undergoing a radical socio-economic and political transformation, generally referred to as the ‘transition’ from a centrally planned, command system to a more or less liberalised, Western-style, market economy. The new thinking and the hopes for economic regenerations in the region were centred mainly upon the tw...

In this study, the effects of flow field types on electrochemical properties polymer electrolyte membrane fuel cells (PEMFCs) humidified with NaCl solution are systematically investigated. The parallel and serpentine were used to investigate PEMFCs. Long-term stability was evaluated for 20 h using chronoamperometry. Fuel both fields showed a decrease in performance because solution. Interesting...
