Abstract
Due to using of inverters in different application such as solar photovoltaic (PV), electric vehicles (EV), harmonic issue in power systems is very important, therefore, different switching methods have been presented for inverters in order to decrease harmonics. The main purpose of this paper is to assess harmonic situation in five-level cascade voltage source inverters (FCL-VSI) using two switching methods, selective harmonic elimination modulation (SHEM) and sinusoidal pulse width modulation (SPWM). To do so, a sample single phase FCL-VSI has been investigated by SHEM and SPWM switching methods and for each method, relation between modulation index and total harmonic distortion (THD) of output voltage has been obtained and also the effect of this parameter on the harmonic content has been studied. In order to obtain favourable results, two switching methods have been implemented on a sample inverter in MATLAB software and results have been evaluated.

Abstract
The purpose for this paper is to identify and rank the criteria affecting museum site selection by utilisation of fuzzy technique for order preference by similarity to an ideal situation (TOPSIS) and analytical hierarchy process (AHP). The paper will develop an integrated analytical hierarchy process, and fuzzy TOPSIS process to upgrade the eminence in decision making for ranking alternative sites for museums. Selecting the best site from various possible posts involves the analysis of different technical, economic, social, and environmental factors. This study presents a multicriteria decision analysis technique based on fuzzy TOPSIS and Analytic Hierarchy Process (AHP). The paper accounts for the ranking of criteria, the incorporated weights of criteria with sub-criteria, and the performance values of the decision matrix. In this replica, the criteria attribute is categorised into the subjective criteria, and objective criteria. Three potential locations were selected based on subtractive summary technique criteria. The sites are ranked according to the view points of different stakeholders using multicriteria evaluation procedure. The results show that the ranking of alternative sites for museums resorts is different for promoters, tourists, and management. This is strongly influenced by the weighing of criteria. However, the recommended multicriteria approach helps stakeholders select the preeminent site according to their interests and objectives. They are also helped to examine the end results of their decision.

Application of Sobol’s Method for Parametric Study of a Robotic Manipulator with Two Flexible Links

489-497Full Text

M. H. Korayem*, A. M. Shafei and A. Azimi

Abstract
The paper’s focus is on studying the sensitivity analysis (SA) of the geometric parameters (including length, thickness and width) of a robotic manipulator with two elastic links. Two important parameters that influence the design of these kinds of robotic systems are the maximum deflection (MD) of the end-effector and the vibration energy (VE) of that point. So, the Sobol’s SA method is applied to determine how these two parameters are influenced by the geometric parameters of the system. The dynamic model of the system is developed based on the Lagrangian formulation. Elastic properties of the links are modeled by applying the Assumed Modes Method (AMM) and the assumption of the Euler Bernoulli Beam Theory (EBBT). Finally, based on the achieved results, a parameter is introduced as a criterion to design the elastic robotic manipulators with the least adverse effects of vibration.

Fatemeh Einollahipeer*, Sanaz Khammar and Ali Sabaghzadeh

Abstract
Sediment, Root, stem and leaf of mangrove tree (Avicenia marina) samples were collected from five stations in Qeshm Island in spring 2013. After preparation, the concentration of every metal was measured using the atomic absorption device Konic NOVAA300. Concentration of the heavy metals Cu, Ni, Pb, and Zn in sediments was measured 42.13, 54.12, 47.90, and 43.61 µg per gram dry weight respectively. The concentrations for the plant’s root were 25.51, 39.76, 9.43, and 18.94 and for the plant’s stem were 24.46, 7.05, 1.17, and 21.65 and for the plant’s leaves were 37.73, 2.44, 0.84, and 33.83 µg per g. According to the calculated Bio Concentration Factor (BCF), plant tissues can be a good bio-indicator for Cu in the region. And, the root is a good bio-indicator for Pb and Ni. For Zn, however, leaf and stem tissues were the best bio-indicators. And the Translocation Factor (TF) was only significant for Cu and Zn in stem and leaf tissues which shows the direct relationship between Cu and Zn concentration in roots and following it, in leaves and stems. Comparing the metal concentration results of the sediment with standard concentrations, it was concluded that only the Ni concentration was critical.

Akbar Rahimipoor

Abstract
The recent bankruptcies of the mega-corporations worldwide and the fluctuations in Stock Exchange in Iran have created the need for instruments to measure the financial capabilities of the firms. Financial ratios are considered to be one of the tools to measure financial capabilities of the companies. Also several models are used to predict bankruptcy. The environmental changes and the exceeding competition between the entities have limited achieving the expected profit for them. Thus, the financial decision making has become more important compared with the past and has forced the mangers to use the advanced techniques in order to make benefit of the new controlling methods. This research is carried out to present the theoretical fundamentals of the research and compare the results of utilizing Falmer and Toffler models in order to predict the companies' bankruptcy. Thus, the data related to 90 firms accepted in Tehran Stock Exchange for the years between 2005 and 2010 were tested. To analyze the data, we used the non-parametric binomial statistical methods. The results showed that in predicting the firms' status with Wilcockson's statistical method, there is a meaningful difference between the results of the two models. Also, in forthcoming studied it was found out that Falmer's model acts more conservatively in bankruptcy prediction than Toffler model.

Abstract
In order to evaluate the effect of soil pH and phosphorous element on growth and yield of tomato plant (Lycopersicom esculentum c.v Calji) in soil culturing, was conducted an experiment as factorial arrangement in completely randomized design with three replications. The first factor was including different soil pHs (6, 7, 8) and the second factor was consisting phosphorous fertilizer (0, 40 and 80 mg P Kg-1 soil) in the form triple super phosphate. To provide nitrogen, 200 mgKg-1 urea was equally used to the plants. Then the traits of flower number, fruit number, plant yield, vitamin C, and TSS and chlorophyll index were recorded. Results indicated that the highest flower number was observed in pH=6.0 and P0 treatment and the lowest in pH=8.0 and P0 treatment. The greatest fruit number was in pH=6.0 and P0 or P40 and the least in pH=8.0 and P0 treatment. The highest chlorophyll amount obtained in pH=8.0 and P40 and the lowest in pH=6.0 and P0 or P40. Generally, application of 40 mg P Kg-1 soil than P0 and P80 had the best influence on the evaluated characteristics. Therefore in the conditions of this experiment, utilization of 40 mg P Kg-1 soil in pH=8.0 or pH=7.0 could improved the quantitative and qualitative traits of tomato plant and fruit.
