Aim: The aim of this study was to investigate the rate of satisfaction and happiness of citizens with parks and urban green space.
Methods: This is a survey study. Six parks were randomly selected among 18 Mashhad large parks. Participants were 360 clients, who were selected by stratified random sampling method. All individuals completed the questionnaires of the satisfaction with park and Oxford happiness version of the park. Data were analyzed using Analysis of Variance (ANOVA).
Findings: The results showed that the level of satisfaction with welfare installations and buildings, green space design, sport facilities, security, furnishings of park, parking and the feeling of happiness is a function of the park type. In addition, the level of satisfaction with green space design is a function of gender.
Conclusion: Satisfaction and happiness as components of health are related with the design of the parks and green space.

The poem of "Rira"’s nima yushij is one of the best modern poems of him. Structural, metrical & lexical features of this poem were caused readers with different horizon of expectations to have sometimes different readings of it in decades. The meaning of this poem has always been concealed in ambiguity by the use of certain words, specially the word "Rira" & the use of symbol in his poems. Reception theory is studing different readings of a text which makes it to recreat every time. Reading of nima’s poetry according to reception theory reveal the difference aspects of his poetry. In this article we intend to express different readings of the "Rira"’s poem in the realms of form & technique as well as the structure of it’s content deal. And also we want to analyize the audience reception from progressive meaning of this poem, diachronically & synchronically. this study show that Nima creates his objects by providing multiple perspectives with the theme of grief and with creating gaps in the text. Meaning in this verse, formed by horizons of expectation, over time. The reader is unaware through the poem & ultimately become conscious. Horizon of expectations prevailing in the poem "Rira" is horizon of expectations And the readers by using the codes of aesthetics assets interpret poem. However, due to the inherent properties of this poem, can be presented each time a new reading of it.

The soaking stage is the most important steps of the parboiling process. Hot soaking requires precise control, because starch granules are gelatinized during soaking. Degree of starch gelatinization (DSG) of rice was measured using differential scanning calorimetry (DSC). This method has high costs and can not be utilized to obtain online data. Thus, in this study a mathematical relationship correlating the DSG of rice to the paddy physical (paddy moisture) -electrical (electrical conductivity (EC) and capacitance sensor output voltage of paddy water) during the soaking portion of the parboiling process was formulated. For measuring of electrical properties of paddy water was designed and manufactured an experimental system of ohmic heater and capacitance sensor for measuring electrical conductivity and voltage, respectively. For doing experiment, paddy (Shiroudi variety) was parboiled by soaking at 60, 65 and 70 oC. At each temperature, samples of paddy and paddy water were selected at five different soaking times. The experimnet results showed that paddy moisture content (21.18-35.1%w.b.), electrical conductivity (0.63-1.6 mS.cm-1) and output voltage of capacitance sensor (216 – 595 mV) of paddy water and rice DSG (5.5 to 31.7%) increased significantly (p<0.05) and exponentially (R2>0.98), exponentially (R2>0.93), quadraticly (R2>0.95) and exponentially (R2>0.96) during soaking, respectively. Linear relationships were fitted between DSG of parboiled rice and physical-electrical properties of paddy water. The results revealed that EC of paddy water be able to predict the DSG of rice during soaking with the lowest regression error.

In this paper, a linear dynamic model for a reaction wheel is identified using experimental analysis. To do this, online input-output data of reaction wheel is sent and received by CAN protocol working with the frequency of one mega bit per second. The experimental hardware consists of reaction wheel, processing board, CAN protocol, and LabVIEW monitoring. Modeling assumes the reaction wheel and its inner control circuit as a black box and takes into account the practical considerations. Initially, behavior of the reaction wheel is examined using test signals for velocity and acceleration as inputs. After that, the test signals are replaced by Chirp and PRBS signals and the output results are saved. According the results obtained in the tests, ARMAX and ARX linear dynamic models are assigned to the motor and different orders of these models are compared with each other to reach the appropriate order of the models. Furthermore, a delay is also incorporated in the model and its proper order is determined by the simulations. Finally, to validate the proposed model, the outputs of the model and plant are compared followed by exerting a new test signal. The results indicate a good agreement between the proposed model and the practical behavior.
