Aims: COVID-19 Vaccination Hesitancy is a public health concern in the world. The present study aimed to determine the prevalence of vaccination hesitancy and its relevant factors using the health belief model among people in northeast Iran.
Instrument & Methods: The present cross-sectional study examined 626 people using convenience sampling. Data were collected through an online survey using a questionnaire based on the health belief model at intervals of 10 September 2021 and 15 October 2021. Data were analyzed by using SPSS 16.
Findings: Overall, 70.6% of the samples reported that they would use the vaccine for free after it becomes available. Health belief model constructs predicted 40% of the variance of vaccination behavioral intention. The results indicated that the perceived barriers were significantly related to using the vaccine, thereby reducing the probability of using the vaccine by 10% (Relative Risk Ratio=0.90, 95% CI: 0.82-0.99). Perceived benefits (Relative Risk Ratio =1.21, 95% CI: 1.11-1.32), perceived susceptibility (Relative Risk Ratio =1.54, 95% Cl: 1.23-1.92), and behavioral intention (Relative Risk Ratio =3.06, 95% CI: 2.23-4.20) had a significant relationship with the probability of using the vaccine.
Conclusion: About one-third of the participants had COVID-19 vaccination hesitancy. Interventions are necessary to increase compliance with vaccination, especially among people with low education levels. The health belief model constructs have a high power of predicting hesitancy and acceptance of COVID-19 vaccination and can be used in intervention programs.

Aims: The objective of this study was to compare growth parameters and phenol content of different safflower (Carthamus tinctorius) cultivars and one wild species of safflower (Carthamus oxyacantha) under urea fertilizer and vermicompost treatments, to distinguish can we use vermicompost instead of urea fertilizer.
Methods: The experiment was carried out under greenhouse conditions. A factorial randomized complete block design with seven replications was used. Experimental treatments were three vermicompost rate; three levels of nitrogen fertilizer; and three types of safflower.
Findings: The number of leaves, leaf area, fresh and dry biomass weights significantly increased with vermicompost application. Urea fertilizer only increased the plant height. The interaction between plant cultivars and vermicompost was significant for phenol content. All growth parameters of safflower except dry biomass weight were significantly different between cultivars. Conclusion: Wild safflower responded more than other cultivars to treatments so it can be used in plant breeding programs. Vermicompost treatment act better than urea fertilizer for growing of safflower, so it can be used instead of chemical fertilizer.

Rice bran sterols have antioxidant activity as well as physiological and biological effects. Because of these benefits, the aim of this study is evaluating the quantity and quality of Iranian rice bran sterols. Three widespread Iranian rice cultivars (Khazar, Hashemi, and Alikazemi) were used for determination of their sterol contents. Two methods of sample preparation were compared and the better one was used in this work. Rice bran samples were saponified directly after acid hydrolysis. Unsaponified materials were extracted, purified by solid phase extraction, silylated, and their sterol fractions determined by GC-MS. The sterol composition (in mg kg-1 bran) of three cultivars (Khazar, Alikazemi, and Hashemi) were 1,330.69, 1,279.95, 1,313.17 β-sitosterol; 747.52, 696.05, 756.8 campesterol; 112.8, 115.36, 114.24 Δ-5-avenasterol, 38.912, 33.08, 38.24 Δ-7-avenasterol; 8.05, 7.07, 7.56c holesterol; 4.20, 3.99, 4.23 brassicasterol; and 2,722.016, 2,706.176, 2,717.68 total sterols, respectively. The results showed that there were no significant differences between the individual and total sterol contents of these three cultivars (P> 0.05), except campesterol, β-sitosterol, and Δ-7-avenasterol. The highest and lowest sterols were ß-sitosterol and campesterol.

The cabbage aphid, Brevicoryne brassicae L. (Hemiptera: Aphididae), is an important pest of canola that can considerably limit crop production through direct or indirect damage. In this study, the effects of Azadirachtin, Tondexir, Palizin, and Thiamethoxam, common insecticides used in managing the cabbage aphid, were investigated on the population growth parameters of this pest. Based on the results, the LC₅₀ values for Thiamethoxam, Palizin, Azadirachtin, and Tondexir were 0.19, 0.63, 1.00, and 3.82 g/L, respectively. Moreover, LC₃₀ concentrations of Thiamethoxam, Palizin, Azadirachtin, and Tondexir were 0.11, 0.10, 0.41, and 1.68 g/L, respectively, applied in the sublethal studies. The cabbage aphids reared on the plants treated with these insecticides had lower longevity, fecundity, and reproductive period than the control treatment. The intrinsic rate of increase (r_m), finite rate of increase (λ), net reproductive rate (R₀), and generation time (T) were lower on Thiamethoxam treatment. Tondexir and Palizin treatments had lower values than Azadirachtin. However, there was no significant difference between the Tondexir and Palizin treatments. The population treated by Azadirachtin had the highest values of growth parameters. According to the results and available information in the context of risk assessment of the studied insecticides, this research recommends the application of Thiamethoxam in the integrated pest management of cabbage aphid.

Aims: Vaginismus disorder is the second most common sexual dysfunction in women, and it is a significant issue in the lives of those affected. This disorder has unfortunate and destructive consequences for the individual’s health, the family unit, and the couple’s intimacy. This study aimed to compare vaginismus-specific schema therapy with conventional schema therapy in terms of their effects on sexual self-assertiveness and self-esteem in women with vaginismus disorder.
Materials & Methods: This quasi-experimental research employed a pre-test, post-test, and follow-up design, including a control group. The statistical population consisted of women with vaginismus disorder who were referred to the obstetrics and gynecology clinic of Payambaran Hospital in Tehran, Iran, in 2021, of whom 45 individuals were selected using a purposive sampling method, and were randomly assigned to three groups through a simple lottery method (n=15 per group). The Persian version of Halbert’s Sexual Self-Assertiveness Questionnaire and the Female Sexual Self-Esteem Inventory (SSEI-W) developed by Zeanah and Schwarz were used. The two experimental groups received treatment in ten sessions, each lasting 90 minutes, while the control group did not receive any intervention. Data were analyzed by repeated-measures ANOVA and Bonferroni’s post-hoc test using SPSS 22.
Findings: Both vaginismus-specific schema therapy and conventional schema therapy were effective in increasing sexual self-assertiveness (Eta=0.83) and self-esteem (Eta=0.94) in women with vaginismus disorder compared to the control group (p=0.001). A comparison of the mean differences between the two intervention groups and the control group revealed that vaginismus-specific schema therapy was more effective in improving self-assertiveness and sexual self-esteem in women than conventional schema therapy (p=0.001).
Conclusion: Vaginismus-specific schema therapy for vaginismus enhances sexual self-assertiveness and self-esteem among women with vaginismus by helping them identify their problems.

The purpose of this research was to study the direct and nondirect relations between the total quality management dimensions and perceived procedural justice with organizational commitment. For this aim, 294 persons from Isfahan city organizations were randomly selected to answer the research questionnaires. The questionnaires were Brooks and Zeitz’s total quality management questionnaire with 24 items, Neihoff and Moorman’s procedural justice questionnaire with 15 items, Meyer and Allen’s affective commitment and Hom and Griffeth’s continuance commitment questionnaire with 3 and 5 items, respectively. All of the above questionnaires were translated and prepared for the first time in this research. The reliability and validity of the questionnaires were verified. The research hypotheses were analyzed using Pearson correlation coefficient and path. The results showed that there was a significant positive relationship between the total quality management dimensions and procedural justice with affective commitment. But among the total quality management dimensions, only leader vision and use of data or information along with procedural justice had positive relation with continuance commitment. The results of path analysis showed that there was a direct relation between affective commitment (and not total quality management dimensions and perceived procedural justice) and continuance commitment. Also there was a relation between perceived procedural justice and affective commitment and between the total quality management dimensions and perceived procedural justice. Finally, the implications of theeffects of total quality management dimensions on affective and continuance commitment were discussed . .

During an earthquake and its effect, what happens on buildings is local damage and destruction which is different due to different characteristics such as diverse earthquake and geotechnical characteristic, different methods of analysis for earthquake-resistant structures, etc. Therefore, in addition to removing structural elements and their falling as debris, a shock and impulsive load could be added to the dynamic load imposed by the earthquake. Impact loads with extreme severity are loads with very low frequency of occurrence, but with extraordinary consequences. Undoubtedly appearing greater success in designing buildings resistant against extraordinary loads is required to forecast the real pattern and the impact of the impulsive loads. In other words, identify all possible failure modes of structures under extraordinary loads is necessary, which requires nonlinear analysis of structures under various loading conditions. Detailed modeling of the impact of an upper floor onto the floor below is feasible using current sophisticated nonlinear dynamic analysis software. Yet the computational effort in the case of large and complex structural systems can be excessive, especially if a detailed model of the whole structure is considered. Moreover, such analysis requires structural engineers with considerable expertise in nonlinear structural dynamics. Due to these limitations, detailed impact modeling is not practical for design applications. Hence, there is an evident need for simple, yet sufficiently accurate methodologies that can be used to establish whether the strength, ductility supply and energy absorption capacity of the lower impacted floor are adequate to withstand the imposed dynamic loads from the falling floor(s). This paper proposes a new design methodology for progressive collapse assessment of floor within multi-storey buildings subjected to impact from an above failed floor. The amount of debris and its scattering and distribution on different floors of a building play an important role in the operation of the impact load. The important point is that how these parameters should be considered in the dynamic analysis and how much the structure’s respond is sensitive to the impact characteristics such as impact velocity, the mass of debris and its distribution. This study has attempted to calculate the dynamic load factor (DLF) for samples of steel beams with an elastic-plastic behavior, and to extract the pattern of debris impact load in order to provide an equivalent loading pattern to estimate the performance of structures subjected to above failed floor(s). The study of dynamic load factors for the samples illustrates that the period of beam, the height of falling and the mass of debris have a noticeable effect on the result so that the DLF decreases by increasing in amount of the period of beams or the mass of debris, as well as it increases by increasing the height of falling. About the achieved patters for the impact load what is important is providing multi-line graphs in order to estimate the dynamic effect of the debris impact

A two dimensional numerical study is presented for steady state performance analysis of a catalytic radiant counter-diffusive burner. In these burners, the gaseous fuel enters from the rear of the burner and passes through the insulation and catalyst layers. The oxygen enters the catalyst layer from the burner surface and opposite to the fuel path. The reaction takes place over the catalyst layer. In this paper, the momentum, energy and species conservation equations in porous and non-porous media are solved using the finite element method in the COMSOL software. The simulations are based on proposed corrections on boundary conditions and combustion rate of methane equation. The simulation results compared with experimental measurements published in the literature for the same geometry and conditions which shows a considerable (10%) improvements. It is shown that diffusion of oxygen through the pad limits the catalytic combustion and controls the fuel conversion in the burner.

Calving records of Iranian buffaloes from April 1991 to June 2010 comprising 1,151 herds with 34,911 calving events were used to evaluate reported secondary sex ratio, stillbirth, and calf birth weight. Logistic regression models were applied to analyze stillbirth and calf sex at birth, and statistical analysis of calf birth weight was performed using a linear mixed model. Overall, the ratio of males to females was 53:47. It was observed that there were no significant effects of herd, calving year, season of calving, dam parity or interactions between these effects on the odds of male or female rates in Iranian buffaloes. Greater odds of calf stillbirth existed for calves born from primiparous buffaloes than from multiparous ones (Odds Ratio (OR)= 1.83; P< 0.0001). The greatest odds of stillbirth was for spring season (OR= 2.47; P< 0.0001), and male births had greater odds of stillbirth than female ones in Iranian buffaloes (OR= 1.21; P< 0.01). In general, male calves were heavier than the female calves at birth (P< 0.01) and the birth weights of calves from cows of parity 4 and beyond were significantly more than the weights of calves from cows of other parities (P< 0.01). Fall-born calves had significantly greater body weight at birth than calves born in other seasons (P< 0.01). It seems that providing good management practices for primiparous and multiparous buffaloes to minimize stress before parturition can reduce stillbirth incidence.

Numerical simulation of gaseous detonation is one of the most challenging problems in computational fluid dynamics (i.e., CFD). The presence of sonic locus at the end of the reaction zone isolates the reaction zone and the leading shock from the far-field flow perturbations, so computational domain may be truncated by artificial boundary conditions. However, some artificial boundary conditions generate spurious waves that introduce some errors into the results. The computational domain is usually considered very large for protecting the domain from spurious waves. A systematic study of boundary conditions’ role in simulation of self-sustained detonation has not been performed yet. In the present study, it is aimed to investigate the influence of the width and length of the computational domain on numerical simulation and the effect of activation energy on the length and width of the domain. Instead of considering a very large domain, the so-called non-reflecting boundary condition is implemented in the present investigation. Characteristics method was employed to define the non-reflecting boundary conditions. Finite length of domain was computed for 1D and 2D simulations. Suitable length of the domain was determined for different activation energies. The results indicate that the suitable length and width of the domain for high activation energy mixtures are larger with respect to the corresponding length and width for low activation energy mixtures. Results also show that, using non-reflecting boundary condition, the computational time decreases considerably for both one and two-dimensional simulations.

Dry bubble disease is one of the most important serious diseases of the cultivated white button mushroom (Agaricus bisporus (Lange) Imbach). It is a cosmopolitan disease having a worldwide distribution. Ten isolates of Lecanicillium fungicola var. fungicola (Preuss) Zare and Gams were collected from mushroom farms. Sensitivity of the isolates to benomyl, carbendazim, carbendazim+iprodione and prochloraz manganese were studied. All the isolates were resistant to benomyl(ED50= 415.45-748.12 mg L^-1), carbendazim (ED₅₀= 1123.87-1879.59 mg L^-1) and iprodione+carbendazim (ED₅₀= 415.45-748.12 mg L^-1). However, most of the isolates were sensitive to prochloraz manganese (ED₅₀=1.62–12.58 mg L^-1). As the primary source of the pathogen inoculum is casing soil and insects, stringent environmental hygiene of the mushroom houses will play a very important role in preventing and controlling the disease.

To obtain an optimum formulation for stabilizers–emulsifier in ice cream, different combinations of three stabilizers, i.e. basil seed gum, guar gum, and carboxymethyl cellulose, at two concentrations of 0.15 or 0.35% with or without E471 emulsifier were studied using a simplex-centroid mixture design. The regression models for physical properties and texture smoothness of samples were also established. Generally, increasing ratios of basil seed gum in gums mixture increased the apparent viscosity of ice cream mixes and smoothness of texture, but decreased the melting rate. Increasing proportions of guar gum enhanced overrun of samples. Results suggested that the combination of 96.94% basil seed gum and 3.06% guar gum at the concentration of 0.35% with 0.15% emulsifier produced the optimum ice cream. Subsequently, the interaction of the obtained optimum formulation with κ-carrageenan as a secondary stabilizer was studied at two levels of 0.01 and 0.02%. The pH, draw temperature, overrun, hardness, and melting rate were measured through physical methods. Rheological and sensory analyses were also performed. Inclusion of κ-carrageenan in formulations decreased the values of instrumental hardness and improved the smoothness of the samples; while it had no significant effects on other properties such as draw temperature, overrun, sandiness, and foaminess.

The purpose of this study was to examine the role of writing self-efficacy and writing strategy in writing performance. To this aim, 110 Participants filled out two questionnaires including writing self-efficacy questionnaire and writing strategy questionnaire and composed an argumentative writing and a narrative writing chosen from TOEFL writing tasks. The data showed no significant relationship between writing self-efficacy and writing strategy use. There was a significant relationship between writing self-efficacy and writing achievement. Furthermore, a negative relationship was found between writing strategy and writing performance. Results of multiple regression showed that writing self-efficacy was the only significant predictor of writing performance. The outcomes of this study can help  teachers to improve their students’ writing. 

1. Introduction
Different factors affect writing in a second/foreign language (L2) such as cognitive, emotional, linguistic, and social factors (Anastasiou & Michail, 2013; Hayes, 2012; Graham & Perin, 2007). Two important factors influencing writing performance are self-efficacy and writing strategies (Ghoorchaei & Khosravi, 2019Pajares, 2003; Schunk & Pajares, 2010). Although writing strategies and writing self-efficacy are important factors influencing writing performance, there has not been sufficient research on these two variables in the context of teaching English as a foreign language, especially in the academic context of Iran, where learners' writings are traditionally evaluated based on grammatical rules and without considering their beliefs about writing and language strategies (Amiri & Saeedi, 2017; Birjandi & Malmir, 2007). Additionally, only a few previous studies in the context of teaching English as a foreign language have examined how the interaction between writing self-efficacy and writing strategies contributes to writing performance, and it is unclear which of these two factors has a greater impact on writing performance. The aim of this study is to explore the relationship between writing self-efficacy, writing strategies, and writing performance among Iranian English language students. It is worth noting that previous studies have not compared the impact of writing strategies and writing self-efficacy across different writing genres. To this end, this study compares the role of writing strategies and writing self-efficacy in argumentative and narrative writing exercises.
Research Question(s)
The following research questions were formulated:
1.    Is there a significant relationship between writing self-efficacy and writing strategies among English language learners
2.    Is there a significant relationship between English language learners' writing self-efficacy and their writing performance in narrative and argumentative genres?
3.    Is there a significant relationship between English language learners' writing strategies and their writing performance in narrative and argumentative genres?
4.    Can writing self-efficacy and writing strategies significantly predict English language learners' writing performance in narrative and argumentative genres?

2. Literature Review
Writing self-efficacy refers to students' beliefs in their abilities to successfully complet writing tasks (Pajares & Valiante, 1997). Previous research has indicated that language learners with higher levels of writing self-efficacy produce better writing (Pajares, 2003; Schunk & Pajares, 2010). In addition, Writing strategies are defined as techniques that L2 learners use to complete a eriting task more efficiently (Collins, 1998). Resrach has indicated that more succesful L2 writers use more effective writing strategies during their writing (Ghoorchaei & Khosravi, 2019). This implies that these two factors are important for L2 writing.  

3. Methodology
In this study, 110 participants were selected through convenience sampling, including 61 undergraduate students and 49 graduate students majoring in English Language Teaching at a public university in Iran. The age range of the participants was from 19 to 35 years (M = 27.86, SD = 7.49), and the sample consisted of 30 men and 80 women. To measure writing self-efficacy, we used Teng et al.’s (2017) questionnaire on a 7 point Likert-type scale and to measure writing strategies, we used Hwang et al.’s (2017) scale on a 5 point Likert-type scale. In addition, to assess participants’ writing performance we asked them to write one narrative writing task and one argumentative writing task, both should include between 200 to 300 words. To achieve inter-rater reliability, two different raters separately assessed all the writings and assigned a score between 0 and 6 for each of the two pieces of writing.

4. Results
With regard to the first research question, our findings did not show any significant relationship between writing self-efficacy and writing staregy use (r = -.072). Then, we examined the relations between self-efficacy and writing performance. Results indicated a positive correlation between self-efficacy and narrative writing performance (r = .282) as well as between self-efficacy and argumentative writing performance (r = .223). Interestingly, with regard to the third research question, we found negative correlations between writing strategies and both narrative writing (r = -.311) and argumentative writing (r = -.273) tasks. Finally, we found that while self-efficacy was a positive predictor of narrative and argumentative tasks, writing strategy use was a negative predictor of narrative and argumentative tasks

In this paper flutter phenomena for a cropped wing with an external store using numerical and experimental methods in a subsonic and incompressible flight regime has been studied. Wing structure was modeled base on von Karman plate theory. A 3D time domain unsteady vortex lattice method was used for wing aerodynamic model and a slender body aerodynamic theory was used for store aerodynamic model. Finally, the aeroelastic governing equations with considering vibratory wing motion has been solved. The experimental tests were performed in an incompressible subsonic wind tunnel. Comparison of experimental results with theoretical analysis shows good agreement with each other especially in calculation of aeroelastic behavior of the wing. In continue, the effects of some parameters such as wing thickness, wing aspect ratio, store position, weight of the store, aerodynamic of the store, store vertical distance from under wing, and center of mass of the store on both flutter speed and instability boundary of the wing have been studied analytically and experimentally. The results show with both increasing aspect ratio and decreasing wing thickness, flutter speed will be decreased. Moreover, change in store position effects on flutter speed of the wing/store configuration. Aerodynamic of the store has no significant effect on flutter speed of the wing/store configuration and increasing store weight leads to increasing flutter speed. Change in center of mass of the store influences on flutter speed.

 The cotton bollworm, Helicoverpa armigera (Hübner), is one of the important polyphagous pests causing serious loss to many economically important crops in Iran. The goal of this experiment was to study the age-stage, two-sex life table of H. armigera on different bean cultivars including white kidney bean (cultivars Daneshkadeh, Pak, and Shokufa), red kidney bean (cultivars Akhtar, Naz, and Sayyad) and common bean (cultivar Talash) under laboratory conditions (25±1^ºC, 65±5% RH, a 16:8 h light-dark photoperiod). The longest and shortest larval period and development time of total pre-adult H. armigera were 19.83±3.83 and 37.58±0.90 days on red kidney bean Akhtar, respectively, and 14.13±0.32 and 31.82±0.42 days on white kidney bean Pak, respectively. The lowest intrinsic rate of increase (r) was on red kidney bean Akhtar (0.115±0.009 day^-1) and the highest on white kidney bean Pak and common bean Talash (0.142±0.001 day^-1). The lowest and highest values of the net reproductive rate (R₀) were on red kidney bean Akhtar (177.3±6.7 offspring) and white kidney bean Shokufa (270.1±6.7 offspring), respectively. The mean generation time (T) on different bean cultivars ranged from 37.03±0.05 to 44.64±0.07 days, which was shortest on white kidney bean Pak and longest on red kidney bean Akhtar. The results revealed that the cultivar Akhtar was the most unsuitable host for population growth of H. armigera.

Large amount of diesel engine waste heats make researchers design systems that utilize the engine waste heat to provide the cooling demand of the heavy-duty vehicles and improve the engine efficiency. Considerable advantages of adsorption cooling system lead to be nominated for this purpose. Coolant and exhaust gases are the main sources of waste heats of diesel engines and using each of them to drive the adsorption cooling system requires its own equipment and working pair. In this paper, a detailed numerical model has been developed and to examine the performance of the cooling system driven by the coolant waste heat with working pair of silica gel-water and also driven by exhaust waste heat with zeolite13x-water working pair. An identical absorbent bed and ambient conditions have been employed to compare the performance of both systems to identify the more appropriate system. The results show that exhaust driven adsorption cooling system has more capability to meet the vehicle cooling demand. Moreover, the performance of the both adsorption cooling systems were examined under variable ambient condition. Results indicate that increase in ambient temperature leads to almost a linear performance drop in both systems that is more considerable in the coolant- driven adsorption system.

The considerable amount of internal combustion engine waste heat through exhaust gases and the capability of adsorption cooling system to be driven by waste heats cause adsorption cooling systems to be interesting for vehicle air conditioning. Low specific cooling power of these systems leads them to be bulkier with respect to other cooling systems. Therefore, practical use of these system has been a challenge. One of the methods to enhance the system performance is adsorber bed optimization which is only feasible by numerical simulations. Hence, an exhaust waste heat driven adsorption cooling system with longitudinal finned-tube adsorber is simulated three dimensionally and considering heat and mass transfer details. Also, both the intra-particle and inter-particle mass transfer resistance has been taken into account in governing equations in order to study the effect of adsorbent particle diameter on the system performance. Results show that among the examined geometrical configurations, bed with 20 fin numbers and fin height of 10 mm is the optimum case corresponding to the maximum specific cooling power. In addition, adsorbent particle diameter in the range of 0.3-0.4 mm is the most suitable diameter for the adsorber bed packed with zeolite13x grains.

In the present study, for the first time, adsorbent bed of SWS-1L/water adsorption chiller with rectangular and trapezoidal finned flat-tube heat exchanger with has been simulated three dimensionally based on the distributed parameters model and finite volume method. Effects of some important parameters on the chiller performance such as bed averaged pressure, temperature and uptake variations with cycle time have been examined for better understanding of bed dynamic behavior. Also, a comparative study between two different configurations of adsorbent bed including rectangular and trapezoidal fins has been conducted based on identical adsorbent mass. For this purpose, bed temperature, uptake and pressure distributions as well as the vapor flow patterns at the end of heating cycle phases and also effects of fin height and spacing on the system performance have been studied. In this investigation at fixed bed length of 20mm, fin height and spacing variations have been examined in the range of 8-20mm and 3-12mm, respectively. Results indicated that the system performance with rectangular and trapezoidal adsorbent beds are almost similar except for those conditions which fin spacing is 3mm and fin height are 14, 20mm. For the mentioned dimensions, the specific cooling power (SCP) of rectangular beds are almost 5% and 17% (for fin heights of 14 and 20mm, respectively) better than those of trapezoidal beds. Maximum and minimum SCP of adsorption chiller with flat-tube heat exchanger were obtained about 882 and 163W/kg for the smallest and the largest bed geometry and operating conditions considered in this study.

Identification of spin maneuver flight characteristics focused in this paper. To analyses an airplane flying quality, identification of the dynamic modes and extracting their characteristics is essential for assessment of the airplane dynamic stability and response-to-control. The paper aims to present a new method for identification of some flight modes, including natural and nonstandard modes, and extraction of their characteristics the same as instantaneous frequency and instantaneous damping ratio, directly from measurements of flight parameters in the time domain in nonlinear flight regime. Firstly, a conceptual method based on the Empirical Mode Decomposition (EMD) algorithm is proposed. The key issue of the EMD algorithm is to represent the signal as the summation of the pattern and detail parts, besides separating them from each other. by utilize the Empirical Mode Decomposition (EMD) capabilities in real-time, a local-online algorithm is introduced which estimates the signal intrinsic mode functions Secondly, by applying Hilbert- Huang transformation to IMFs obtained by EMD algorithm the flight characteristics the same as instantaneous frequency and instantaneous damping ratio for flight mode has been estimated from spin measured flight data. The results indicate the appropriate performance of the identification method in nonlinear flight regime.
