Uniform modeling of parameter dependent nonlinear systems

引用

Journal of Zhejiang University-Science C(Computers and Electronics) 2012年第11期13卷 850-858页

作者： najmeh EGHBAL Naser PARIZ Ali KARIMPOUR Department of Electrical Engineering Ferdowsi University of Mashhad

This paper addresses the problem of approximating parameter dependent nonlinear systems in a unified framework. This modeling has been presented for the first time in the form of parameter dependent piecewise affine systems. In this model, the matrices and vectors defining piecewise affine systems are affine functions of parameters. Modeling of the system is done based on distinct spaces of state and parameter, and the operating regions are partitioned into the sections that we call 'multiplied simplices'. It is proven that this method of partitioning leads to less complexity of the approximated model compared with the few existing methods for modeling of parameter dependent nonlinear systems. It is also proven that the approximation is continuous for continuous functions and can be arbitrarily close to the original one. Next, the approximation error is calculated for a special class of parameter dependent nonlinear systems. For this class of systems, by solving an optimization problem, the operating regions can be partitioned into the minimum number of hyper-rectangles such that the modeling error does not exceed a specified value. This modeling method can be the first step towards analyzing the parameter dependent nonlinear systems with a uniform method.

Selective Sensing Characteristics of Ca Doped BeO Nano-sized Tube toward H20 and NH3

引用

Chinese Journal of Chemical Physics 2013年第5期26卷 612-616,I0004页

作者： Maziar Noei Vali Zare-Shahabadi Seyedeh najmeh Razi Department of Chemistry Mahshahr Branch Islamic Azad University Mahshahr Iran Young and Elite Reaserchers Club Mahshahr Branch Islamic Azad University Mahshahr Iran

By means of density functional calculations, the structural and electronic properties of chemical modification of pristine and Ca-doped BeO nanotubes were investigated with NH3 and H20 molecules. It was found that the NH3 and H20 molecules can be adsorbed on the Be atom of the tube sidewall with the adsorption energies of about 36.1 and 39.0 kcal/mol, respectively. Density of states analysis shows that the electronic properties of the BeONT are slightly changed after the adsorption processes. Substitution of a Be atom in the tube surface with a Ca atom increases the adsorption energies by about 7.4 and 14.7 kcal/mol for NH3 and H20, respectively. Unlike the pristine tube, the electronic properties of Ca-doped BeONT are sensitive to NH3 and H20 molecules. Also, the Ca-doped tube is much more sensitive to H20 molecule than NH3 one.

Urban buildings and urban traffic network are considered as the vital arteries of cities which have particular effects especially after the crisis in the search and rescue operations. The aim of this study is to determine the vulnerability of urban areas especially, buildings and traffic networks using multicriteria geographic information systems and decisionmaking methods. As there are many effective criteria on the seismic vulnerability that they have uncertain and vague properties, the method of this paper is applying fuzzy ordered weighted average(OWA) to model the seismic vulnerability of urban buildings and traffic networks in the most optimistic and pessimistic states. The study area is district 6 of Tehran that is affected by the four major faults, and thus will be threatened by the earthquakes. The achieved results illustrated the vulnerability with different degrees of risk levels including very high, high, medium, low and very low. The results show that in the most optimistic case 14% and in the pessimistic case 1% of buildings tolerate in very low vulnerability. The vulnerability of urban street network also indicates that in the optimistic case 12% and in the pessimistic case at most 9% of the area are in appropriate condition and the North and NorthEast of the study area are more vulnerable than South of it.

Objective: To investigate the impact of Humulus Lupulus L. hydroalcoholic extract on the body weights, reproductive organs, sperm quality and hormone levels in male rats. Methods: By simple random sampling method, seventy male Sprague-Dawley rats were randomly assigned to 7 groups including control group [distilled water, 1 mL/(kg·d)], Tween 80 group [25% Tween 80 solution, 1 mL/(kg·d)], olive oil group [olive oil, 1 mL/(kg·d)], diethyl stilbestrol(DES) group [DES, 100 μg/(kg·body weight)], H50, H150 and H450 [50, 150 and 400 mg/(kg·d) of Humulus Lupulus L extract, respectively]. The administration was performed via gavage once daily for 7 weeks. Body and reproductive organs weights including testes, seminal vesicles, epididymis and prostate were weighted and epididymal sperm quality were determined by digital balance. Blood samples were collected and serum free testosterone(T), luteinizing hormone(LH), follicle-stimulating hormone(FSH), and estrogen(E2) levels were measured by rat specific enzyme-linked immunosorbent assay. Results: The percentage increase in mean body weights of rats in the DES and H50, H150 and H450 groups decreased significantly compared to olive oil and Tween 80 groups(all P0.05). Conclusion: Humulus Lupulus L. extract significantly increased the seminal vesicle and testes weights and reduced the sperm motility.

Chinese Journal of Oceanology and Limnology 2016年第1期34卷 13-18页

Effects of irradiated and non-irradiated Ergosan extract(alginic acid) on rainbow trout growth performance and skin mucosal immunity were compared. Ergosan was irradiated at 30 kGy in a cobalt-60 irradiator. A total of 252 fish(128.03±9.4 g) were randomly divided into four equal groups,given the basal diet either unsupplemented with Ergosan(control group) or supplemented with crude Ergosan(5 g/kg),ethanol-extracted Ergosan(0.33 g/kg) or irradiated Ergosan(0.33 g/kg) according to this protocol: basal diet for 15 days,treatment diet for 15 days,basal diet for 10 days and treatment diet for 15 days. Highest growth performance was observed in fish fed irradiated Ergosan(P<0.05). Dietary administration of different Ergosan types did not cause any changes in mucus protein level,but improved alkaline phosphatase level and hemagglutination titer compared with the control(basal diet without Ergosan) on day 55 offeeding trial(P<0.05). Furthermore,the highest value of lysozyme activity was observed in gamma-irradiated Ergosan on day 55. In conclusion,gamma-irradiated Ergosan at 0.33 g/kg was found to improve growth performance and mucus biological components significantly in comparison with the control group(basal diet without Ergosan).
