The aim of this research was explanation of color changes and behavior of French fries during the process as a mathematical model at various temperatures. Materials and Methods: Blanched potato stripes were fried using a fryer equipped with thermo controller where the sunflower oil was used as a frying media at the temperature of 145, 160 and 175 ºC for 60, 120, 180 and 240 seconds. Surface temperature of the product was measured using T type thermocouple that was located about 1mm below the surface of the strip and recorded using data logger by 2 seconds intervals during process. Color parameters as brightness (L), redness (a) and yellowness (b) were achieved using Lovibond apparatus and kinetic model was fitted on their changes versus time using MATLAB software version of 2009. Finally, critical temperature of color changes during frying was specified by carrying out statistical analysis of equivalent values of color change intensity (∆E∞) as completely randomized design and Duncan mean comparison with 95% confidence level using SPSS software version of 19. Results: The results of this experiment showed that the main part of color parameter changes occurred during early stages of frying process. Higher temperature caused less brightness (L), more redness (a) and more yellowness (b) (more acceptable). The temperature of 160 ºC can be defined as the critical temperature for significant changes (P≤0.05) in the color intensity. Conclusion: Kinetic of crust color changes in French fries follows the raising exponential equation of R2=0.99. Applying high temperature and short time process can be suitable for the control of color quality and therefore food safety. Manuscript profile -

Power system planning and operation, power network reorganization, and many optimization s MoreIntroduction: Load distribution analysis is a fundamental and basic study for all power networks, including distribution networks, which are used in steady-state conditions. Power system planning and operation, power network reorganization, and many optimization studies require a large number of load distribution calculations in normal and emergency situations. Due to the nonlinearity of the system of load distribution equations, it is necessary to use iterative solution methods to solve it. In addition, due to a large number of power grid buses, matrix algebra is used. Some of these applications require fast iterative solutions of load distribution and therefore it is very important that load distribution analysis is performed efficiently. A number of load distribution algorithms are specifically designed for distribution systems. One of these methods considers bus voltages as state variables and works based on an iterative algorithm and uses special methods to increase convergence.Method: The proposed algorithm of this paper called SDLF in this article does not need special matrices and complex programming. In this method, load distribution can be achieved easily with only a simple vector that shows the priority of buses, which we call BPV, and by using the forward-backward sweeper algorithm. It is worth mentioning that the BPV vector itself is extracted from the network topology. This work can be done both visually from the electrical diagram of the network and from the data matrix of network D by MATLAB software. Finding: In terms of the convergence of the solution, increasing the repetition has led to an increase in accuracy, and as a result, the 10th repetition has been chosen as a relatively accurate result to confirm the validity of the method, considering the required engineering precision. The obtained results show that even in the first iteration, an acceptable accuracy for the voltage range has been obtained. In steady state analysis of power networks, the voltage amplitude is more important than the voltage phase. The noteworthy point is that in calculating the voltage phase, it is not necessary to update its value in each step, and it is enough to calculate the voltage phase after obtaining the voltage ranges. Conclusion: In this article, a new method called SDLF is introduced to study the load distribution of distribution networks. The results of the implementation of the proposed method, with an acceptable engineering error, can be used in the common applications of power networks in the first iteration, and based on this, it can be used as an online load distribution in SCADA systems. The effectiveness of the method was checked on the test network of 33 IEEE buses in the text of the article and its validity was confirmed. The introduction of the BPV bus priority vector made it possible to avoid using complex matrices and additional calculations and to reduce the time of load distribution calculations.

A fuzzy controller was designed to guide this robot inside the tube, and its control system was implemented using direct current motors for each of the robot's wheels. The ability of the fuzzy controller of the robot to follow the desired input speed and its response characteristics in the steady state were investigated, and the presented results showed that the fuzzy controller performs better in following high speeds and has a better transient response at these speeds. Using the optimal torque distribution system, the robot control system is improved and the output signal of the fuzzy controller can be sent to the robot wheels in a targeted way. Therefore, the application of this method caused a significant reduction in the power consumption of the robot and optimization of its energy consumption. This designed robot has a high potential for making an accurate sample, commercialization and responding to the current needs of the country's oil and gas industry due to its less expensive mechanism compared to similar ones.

First, the dynamic model of milling with delay is developed from condition form to integral form. Then every period is discretized in limited time sections. Full discretization method is used for manual calculation of system integral. In every small time interval, the Lagrange 3th degree multi term is applied to interpolate the condition part. Furthermore the Lagrange linear multi term is also used for interpolation of delay- and period parts. A discrete dynamic design is achieved. Now it is possible to determine the matrix of condition transition in a time interval. Using this matrix by Floquet theory, lets to predict the stability lobe diagram. A basic example provides verifying of this method by comparison with results from literatures. The MATLAB program to calculate the problem is attached. Manuscript profile -

Despite heavy expenses, it is necessary to use pile. Pile foundations are much more expensive than spread and mat foundations; hence, determining number, dimensions and distances should be done with special care so that these parameters are not determined excessively. For optimized design of pile groups, cost analyses based on settlement equations and bearing capacities to determine number, dimensions and piles distances are necessary. In this research, a computer program has been written in MATLAB language, and by using genetic algorithm which can optimize pile groups design. Outputs of this computer program consist of diameter and length of piles, thickness of pile cap, number of piles and their distances in each direction; therefore, this computer program can design an optimized pile group which tackles technical problems while it is the most economical.

Various approaches are used in the evaluation of this performance, which can be referred to as continuous and discrete approaches. In the continuous approach, two-dimensional and three-dimensional analyzes can be used. One of the very important disadvantages that can be pointed out in the three-dimensional analyzes of piles is the increase in computational costs. Therefore, improving the accuracy of two-dimensional analyzes in order to reduce computational costs is inevitable. The present study has used Abaqus finite element software to evaluate the response of a single pile embedded in single— and double-layer sand under two earthquake records (far-field and near-field). The subsequent stage involved employing the wavelet transformation technique to analyze the signal derived from the pile cross-section. The present study utilized the acceleration time histories of the pile head as the input signal for wavelet transformation. The result showed that the wavelet energy for the pile head signal was higher in the near-field record than in the far-field record. The analysis indicated an 11% and 41% increase in wavelet energy for single-layer and double-layer profiles, respectively. This increase in wavelet energy is due to the significant increase in horizontal displacement of the pile under near-field records compared to far-field records. Therefore, by implementing signal processing analysis employing continuous wavelet transformation on the horizontal acceleration of the pile section, relevant information regarding the type of earthquake records that occurred at the site can be extracted.
