The seismic performance of a steel structure depends on various factors, such as the design, materials, and dimensions. One important aspect to consider is the span length of the structure, which can influence the seismic response and the overall performance of the structure. In this study, a 10-story steel structure with chevron bracing system was designed with ABAQUS software and finite element method. The structure was subjected to the El Centro earthquake for 25 seconds using the dynamic analysis method. Furthermore, the W index was defined equal to the span length to the story height, and the values of 0.67, 1.67, and 2.5 were considered for W. The results showed that the increase of the W index has direct relationship with the changes in the seismic parameters of the structure, including the displacement and acceleration, the von mises stress, the acceleration-time, and the displacement-time diagrams in the roof and the base shear force. Changing the index from 0.67 to 1.67 and 2.5 has caused an increase of 13.34% and 16.67%, respectively. Changing the index from 0.67 to 1.67 and 2.5 has caused an increase of 10.15% and 52.28%, respectively. Changing the index from 0.67 to 1.67 and 2.5 has caused an increase of 43.75% and 109.37%, respectively. Changing the index from 0.67 to 1.67 and 2.5 has caused an increase of 20.83% and 47.91%, respectively.

In this study, the substance was theoretically examined using computational techniques to provide more analysis on the cytarabine inhibition on the aluminum surface. Through DFT and molecular dynamic simulations, the quantum chemical approach was used to study the parameters. Al (110) surface was chosen because of the atoms' close proximity and density on the surface. The local and global reactivity, as well as the Fukui function, were computed to determine the molecule's reactivity. The mechanism of cytarabine is assumed to display physiosorption with aluminum surface based on the predicted adsorption and binding energies (-52.476 and 52.476 Kcal/mol) and the negative value of the EHOMO which is -5.133eV. In conclusion, the molecule is described as an efficient aluminum inhibitor having just a mild inhibition on the studied aluminium surface.

Energy carriers as one of the important inputs of production as well as consumer goods of households, play a very important role in determining production costs and household expenditures. Price fluctuations in each of these carriers will cause fluctuations in production costs, consumer spending, and ultimately inflation. The extent of this fluctuation, depending on the importance and share of each carrier, can be examined in the total basket or in the issues of production and consumption. These oscillations can be divided into two parts: "direct load" and "indirect psychological load". Indirect psychological burden shapes the expectations of households and producers, and direct burden reflects the direct impact of price fluctuations. Statistics show that the relative price of energy carriers is lower than the price of other domestically produced goods or energy prices in the region and the world, and this gap between the price of domestic energy carriers compared to world prices has led to its growth over the last decade Accelerate and increase the share of carrier costs in the total consumer basket. Identify the gap between the mentioned variables, the mechanism of presenting corrective or supportive, and institutional policies to reduce the possible negative consequences and put the economy on the path of increasing the efficiency of production factors. This article examines the challenges of managing the consumption of energy carriers in Iran.

In this study, knowledge management in commercial companies has been studied. In an age where knowledge determines the power and wealth of societies, knowledge management and transfer has become the most important task of societies and organizations within them. Organizations that effectively acquire, create, transfer and use knowledge to improve and improve they do their activities and functions. An organization without knowledge cannot organize itself and survive as a living and dynamic military. Organizations are determined to acquire knowledge and use it. Managers who make tough decisions are more likely to seek out experienced people than to constantly expose their knowledge to decisions instead of searching for information in databases. According to studies, managers obtain two-thirds of their information and knowledge by referring to writings and documents (Davenport, 2000). Moves and promotes the knowledge of organizations and is one of the important factors in empowerment. Build organizations to compete in the supply of the new global economy. Today, organizations are in dire need of increasing quality, value, service and speed in order to be able to expand in the market, and this trend will certainly become more important in the future and will be considered as the biggest organizational competitive advantage in the global economy.

This study examines the definition of organizational knowledge in industrial and commercial companies. Knowledge in an organization is knowing the reality or situation of something, however awareness and understanding that have been obtained through experience, study, exploration and mental communication and have been recorded in various forms and the purpose of knowledge management is to identify, acquire and organize and Appropriate storage and transfer of knowledge in order to improve and change the perceptions and performance of employees at different levels of the organization at the appropriate time, which prevents the outflow of intellectual and mental assets from the organization when leaving knowledge agents. Knowledge management consists of various elements such as knowledge production, knowledge acquisition, knowledge storage and transfer and sharing. However, it can be said that knowledge transfer is the movement, distribution and dissemination of knowledge between individuals and mechanized and non-mechanized knowledge bases. In two ways, for which two types of strategies are conceivable, the strategy of person-to-document transfer and the strategy of person-to-person transfer. The role of human resources training and development professionals in the management and knowledge transfer process is critical. These maps can be created through various activities. In fact, education management and human resource development can address the shortage of information and knowledge in a timely manner and lead to the horizontal growth of people in jobs by resorting to knowledge management system along with other resources to meet educational needs.

Schizophrenia has existed throughout history, as ancient Greek physicians have described it with different symptoms, but it was not seriously studied until the second half of the nineteenth century, and from the second half of the nineteenth century the classifications related to Schizophrenia developed, which of course was very personal and tasteful. Arnold pick was the first to use the term Dementia praecox to describe the apparently Hebephrenic type of psychiatric disorder. Schizophrenia is a mental disorder characterized by persistent or recurrent forms of psychosis. The main symptoms include hallucinations, delusions, and disordered thinking. Schizophrenia is a chronic and severe brain disease that affects a person's thoughts, feelings, and behaviors, as well as impairing a person's realism. The onset of the disease is between the ages of 16 and 30, but in rare cases it is also seen in childhood. The prevalence is equal in men and women, but the onset age is earlier in men than women. The age of onset in women is two peaks. The age of onset is 10 to 25 years for men and 25 to 35 years for women. The onset of the disease before the age of 10 and after the age of 60 is rare. In cases that start after the age of 45, it is called schizophrenia with a late onset.

Design, supply and drilling (EPD) contracts, referred to in the downstream industry as turnkey contracts, are new contracts in the drilling industry that can be attractive to both employer and contractor. In this type of contracts, the design, supply of equipment and goods, as well as drilling wells are the responsibility of the drilling contractor. Therefore, all risks in all three stages are the responsibility of the contractor and in this regard, these contracts are attractive to employers. Therefore, by managing and allocating new risk by placing conditions and clauses, these contracts can be replaced by the format of previous contracts. Studies and researches in the field of EPD contracts in the world and Iran in the field of production wells have been done, also projects in this field have been done in South Pars field. However, a comprehensive and complete research on this issue has not been done yet. In the exploration of exploratory wells, in the world and in Iran, research on the contractual risks of this type of contract and how to allocate these risks has not been done yet, and as a result, a project with this title has not been realized yet.

Corona electric discharge phenomenon occurs when the electric field intensity exceeds the corona threshold. In the analysis of this paper, three types of hypotheses of partial charge (electrons, positive ions, negative ions) generated in the air due to corona electrical discharge are considered. The physical process is produced along with the changes and dynamics of the electric charge applied to the field by the charge movement which has velocity due to electric fields and motion due to slope (diffusion) and we will also see losses in electric charge. In this paper, electric load evaluation on a polymer surface by a positive impact corona in the air was performed. Output (circuit current) and input (electric fields and electric charge space density) are considered in computer simulation analysis. Different models have been used to identify the corona, depending on the intensity and extent of the voltage surges. The dynamics and distribution of electric charges and electric fields are analyzed and compared by two models of corona charging (glow and burst impulse).

Due to the accelerated trend of transferring most of the activities to contracting companies, the rate of indicators related to occupational accidents has grown alarmingly and has led to the discussion of evaluating and selecting construction contractors in terms of health. Safety and the environment are of paramount importance. The presented model was performed by analyzing quantitative studies as well as completing a specific questionnaire and field surveys, and the sample size was determined to be 252 with a 95% confidence level and a 5% error probability. The test method was performed using Cameo and Bartlett test and confirmatory factor analysis. The results of the present study indicate that the highest intensity of impact is related to the human resources criterion and the lowest intensity is related to the planning criterion. The proposed model can meet the growing need of organizations for a comprehensive model of evaluation and selection of contractors.

Still, one of the most basic and often overlooked questions is about contract risk planning. If the scope, technical implications or requirements of a contract are not clear, everything will be opaque. This risk is for the buyer because it was paid for what was not due and for the seller may lead to payment by the buyer or the buyer's claim for damages or termination of the contract. As discussed earlier, contractual disputes arise when one or both parties feel that their rights have been violated. Managing expectations is essential and requires effective communication. For the seller, this includes understanding what the buyer or customer wants, guiding the buyer to what the seller can provide, and clarifying what can be done in the contract. Sometimes it is to reassure the parties by each other of delivery restrictions and what is not available and whatever is within the scope of a contract or outside of it. Effective and transparent communication about the scope of work, technical specifications and requirements promotes the expectations of both parties and reduces the likelihood of failure of one party's activities that lead to frustration of the other party.

Distribution of distributed generation resources in distribution systems has several advantages, including reducing losses, improving voltage profiles, reducing pollution, and increasing system reliability. However, one of the most important points regarding the placement of these resources in distribution networks is economic issues and the return on investment and the increase in profits from the placement of these resources. On the other hand, due to the privatization of power systems, other distribution networks will not necessarily own the distributed generation resources. Therefore, despite choosing the location of scattered production resources by the owners of scattered production resources and pricing their production power, the selection of purchasing power from each of the scattered production units or the national electricity system is done by the distribution network operator. It will be for supply. Thus, owners of scattered production resources must choose the location and price of the production capacity of their resources in such a way that their profit is maximized and at the same time the amount of payment paid by the network operator is minimized. Therefore, in this paper, the issue of location and optimal pricing of distributed products is considered to increase the profit of the owner of scattered production resources provided that the distribution company pays the minimum payment cost and the method used to solve this problem is the ant-optimization algorithm. It is inspired by the ant's milk hunting mechanism and is a powerful optimization algorithm.

Exposure to dust in the air is one of the most common environmental hazards in workshops that can have devastating effects on health. In this study, workers' exposure to particles in inhaled air by conventional methods as well as GIS has been investigated. The research was performed cross-sectionally-analytically and the sample size was determined through homogeneous exposure groups and environmental and individual exposure was performed based on standard methods and individual and environmental sampling methods. The obtained data were analyzed using GIS software to determine the distribution maps. In this paper, the mean concentration of exposure to dust for each individual in the matched exposure groups was 8.361 mg/m. The highest level of individual exposure was estimated in the powder operator with a value of 21313 mg/m3 and the lowest in the fine wire emperor with a value of 1.97 mg/m3. The minimum environmental concentration in the cutting hall was 0.305 mg/m and the maximum value was 22 mg/m3 in the powder hall. The results of the evaluation with AIHA criteria in all methods showed that weaving, material, and packaging halls have the highest concentration and cutting halls have the lowest dust concentration. Comparison with the GIS method showed that powdering, materializing, and packing halls have the highest concentration and cutting halls have the lowest dust concentration. Comparison with the GIS method showed that in this method, more people are classified in the risk area.

Nowadays, to involve wind turbines in controlling the network frequency, drop and inertia control methods are usually used for variable speed wind turbines. Adjusting the benefits of droop and inertia control loops is very effective on the performance of wind turbines, but due to the variability of wind speed and network conditions, adjusting the control coefficients that produce the best response in all conditions is impossible. In this paper, a new method for the comparative regulation of the gain of the droplet control loops and the inertia of the doubly-fed induction generator (DFIG) is presented. Also, due to the relief of problems and shortcomings of wind turbine and network modeling, the use of a data-driven method, which operates only on the input and output of the system, has been proposed. In the new idea presented for faster control and prevention of sharp frequency droop, new equations have been calculated to update the coefficients of the control loops using the second fault derivative, which is used in the comparative adjustment of the gain of the droop and inertia control loops. In the proposed control method, the next instantaneous output is first estimated using KVNN and then the coefficients of the frequency control loops are adjusted adaptively using the Hessian matrix. The simulation results for a DFIG wind farm show the proper performance of an adaptive method based on data-driven control in increasing the minimum frequency and improving the network frequency in a permanent and transient state when a fault occurs.

The stability of the power system is essential to ensure its proper functioning. In recent years, Flexible AC Transmission Systems have been considered as one of the effective methods to improve the control ability of the power system and power transition constraints. One of the devices of the parallel flexible alternating current transmission systems is STATCOM which can improve the power system dynamic and transient voltage stability. In this study, a new method for designing the damping controller was proposed to improve the transient power system stability in a single machine network connected to an infinite bus. The STATCOM controller problem in a wide area of the system function was considered as an optimization problem with multi-purpose objective function. Also, the Honey Bee Mating Optimization Algorithm was used to determine its parameters.

One of the most commonly used equipment in the power system, which is exposed to various types of faults for various reasons, is high and low voltage pressure cables. Due to the fact that cables, either power or distribution cables are mostly transported from underground, despite their further reliability in airway, they are more difficult to repair and possibly replace in case of fault, in line with this the correct fault detection and location of them is of utmost important. In this paper, as is clear from the title of the research, the Fourier transform and Modal transform methods are used to find the type and location of faults, so that the efficiency of the selected method for detecting and locating the faults in underground transmission cables is examined and the speed and accuracy of finding a solution to the problem is assessed. In this paper, it is expected that the Fourier transform method, followed by the Modal transform has substantial speed and accuracy in determining the type and location of the faults. Meanwhile, the detection and location indicators are used to determine the type and location of the fault, which as shown in the simulations, will have efficient performance. The sample model is simulated to demonstrate the correctness of these methods. The simulation results from MATLAB and EMTP/ATP software confirm the precise and rapid performance of the proposed method.

In this work, coal residue (pitch) was used to produce an inexpensive protective coating. The residue is primarily rehabitated for just to be suitable for use as a coating material (reference coat) by dissolving it in benzene in a ratio of Pitch/Solvent (P/S) = 3:1 by weight. The reference coating was then mixed with polyurethane (commercial type) in percentages ranging from 5 to 15 % by weight of the solid tar pitch. Well mature mortar cubes (7x7x7cm) with a (w/c =0.4) and sand-cement (s/c= 2.75) were cast and covered with the prepared coatings. The cubes were then soaked individually in tap water, MgCl2-5% conc. and H2SO4- 3.0% conc. for different periods of time. The last two reagents represent sea water and 5 years complete immersion in sewage water respectively. The effect of reagents on the compressive strength, water retention and weight was measured for the cubes. The results revealed that, all prepared coatings gave satisfied physical characteristics. Addition of PUR up to 10% by weight of coal residue produced coating materials with the most favorable physical and chemical behavior.

In general, the stability of the power system can be considered a feature of the system that enables it to remain in equilibrium under normal conditions and regain a different acceptable state if affected by disturbance. Instability in a power system may take many forms, depending on the composition of the system and its operating modes. In order to evaluate the proposed method in damping transient fluctuations and network stability, a study has been carried out on a typical network. Since the topic of the article is in the field of transient stability, in part of the paper, braking resistance modeling in transient stability studies has been investigated. In the section on brake resistor control, brake resistor control is introduced by a switched Thyristor, using the trapezoidal method. Finally, the simulation results of the studied network are presented with the presence of TCBR and its capability of damping in the desired network.

In this paper, a time-based model for distribution network development planning is proposed, considering the possibility of using distributed electricity generation technologies and the existence of capacitor banks. The proposed model specifies the location, capacity, and timing of the use of distributed generation technologies and capacitor banks as well as the schedule for increasing the capacity of the grid lines. The Genetic Enhanced Algorithm is used to solve the stated problem to optimize the network development plan including the time, location and capacity of DG and capacitor banks in the distribution network as well as to optimize the investment cost and operating cost. It was also implemented in a MATLAB programming environment to validate and evaluate the effectiveness of the proposed solution to the problem of distribution network development planning on a 17-bus radial distribution network.
