        Recent advances in wireless electronic and communications provide us the ability to build small, economical sensors with low power consumption and many diverse applications. Limited energy capacity of sensors is a huge challenge that will affect these networks. Clustering has been used as a well-known method to handle this challenge. To find appropriate location of clusters' heads, imperialist competitive algorithm as an emerging topic in computational intelligence has been used. Clusters' heads are connected in a three-level model so that cluster heads with low energy capacity and far from station are considered as level three indirectly communicating with base station. This eventually increases lifetime of wireless sensor networks. Manuscript profile

        Despite the success of the Colonial Competition Algorithm (ICA) in solving optimization problems, this algorithm still suffers from repeated entrapment in the local minimum and low convergence speed. In this paper, a new version of this algorithm, called Modified Orthogonal Chaotic Colonial Competition (COICA), is proposed. In the policy of absorbing the proposed version, each colony seeks the space to move towards the colonizer through the definition of a new orthogonal vector. Also, the possibility of selecting powerful empires is defined through the boltzmann distribution function, and the selection operation is performed through the roulette wheel method. The proposed multilevel perceptron neural network (MLP) algorithm is used to classify standard datasets, including ionosphere and sonar. To evaluate the performance of this algorithm and to evaluate the generalizability of the trained neural network with the proposed version, the K-Fold cross-validation method has been used. The results obtained from the simulations confirm the reduction of network training error as well as the improved generalizability of the proposed algorithm. Manuscript profile

        Recommender systems are the systems that help users find and select their target items. Most of the available events for recommender systems are focused on recommending the most relevant items to the users and do not include any context information such as time, location . This paper is presented by the use of geographically tagged photo information which is highly accurate. The distinction point between this thesis and other similar articles is that this paper includes more context (weather conditions, users’ mental status, traffic level, etc.) than similar articles which include only time and location as context. This has brought the users close to each other in a cluster and has led to an increase in the accuracy. The proposed method merges the Colonial Competitive Algorithm and fuzzy clustering for a better and stronger processing against using merely the classic clustering and this has increased the accuracy of the recommendations. Flickr dataset is used to evaluate the presented method. Results of the evaluation indicate that the proposed method can provide location recommendations proportionate to the users’ preferences and their current visiting location. Manuscript profile

        Competitiveness is a complex and multidimensional concept, making it possible to get high-quality feedback from the environment. This research was designed in order to improve the competitiveness capability; because competitiveness plays a basic role in an organization’s productivity. To this end, we employed the cognitive complexity as a strategic concept using its key components including market sensation and customer psychology. Moreover, we examined three dimensions of market intelligence to develop the model. Data was collected through in library studies and interview with master students of Tehran University, school for performing arts and music. Collected data was analyzed by the system dynamics method with the aim of variables’ future behavior estimation. In doing so, 2 scenarios were simulated using Vensim PLE software. In the first scenario, market sensation led to strategic innovation through requisite infrastructure to create and disseminate intelligence. In the second scenario, customer psychology was identified as an effective factor in market accountability and competency creation. Findings showed that little improvement in customer psychology causes more customer perceptual competency. To understand and interpret the complex environment, designing an integrated and intelligence information systems is recommended. This is required to achieve both strategic innovation and organization competency simultaneously in order to increase the capacity of competitiveness. Manuscript profile

        The author of this research is an experienced investor with a long-standing and established presence in the industry and has a dynamic relationship with local universities. He considers the first step as clearly defining the goals of academic self-governance, followed by a thorough identification of incentives for self-governance at higher education institutions. Why should universities be self-governed?What measures need to be taken to achieve “self-governance” at universities?Below, the underlying reasons for progressing towards “self-governance” in higher education institutions will be explained in detail: -The need for investment to develop infrastructure pertinent to universities. -The Government’s limited and arguably insufficient funding for universities. -The need to foster financial and income diversity among universities. -Benefiting from the process of financing as a tool for transformation. -The need to increase welfare benefits and enhance general standards of living for academics through wealth creation by universities themselves. -The need for quantitative and qualitative enhancement of resources made available to university researchers, specialists, and consultants in the field of Industry and Economy. -Helping mitigate the “brain drain” crisis . -The need for improved standards of accountability with respect to university stakeholders. (Through a more prominent involvement of universities in the nation’s development process). -The need for innovation in the field of technology. -Increasing the competitiveness of local universities in accordance with international standards. -The need for independence and financial autonomy of universities to grow and evade restrictions. In this section, we will attempt to clarify our definition of "self-governance at universities" as financial self-governance – aiming to minimize reliance on public funds as the main source of endowments. By emphasizing on the lawful self-governance of universities, in line with their institutional missions, the potential of universities will no longer be constrained by the “what ifs” and “only ifs” commonly heard at academic institutions dependent on public funds. The need for self-governance (financial self-sufficiency) can also be traced in the Constitution. Finally, it is essential to note that by paving the way for self-governance at universities through the allocation of responsibilities among academia as their “national commitment”, we can help transform the industry and promote the sustainable development of the country. Addressing the methods of achieving self-governance, we should reevaluate our perception of universities by looking through a different lens. Perceiving universities as “enterprises” or “firms” reveals the nuanced dimensions of the issue and allows for greater emphasis to be put on "industry" as the main customer of universities. At the third and final stage of the quest, the deviser of the Bridge plan suggests that there will be a systematic yet creative connection between the notion of academic self-governance and the Bridge plan itself. The wagons of academic self-governance will fit perfectly on the railway tracks of the Bridge plan, and the train will head for the destination. In this part, we will provide a brief overview of the Bridge plan for those not familiar with it. The Bridge Plan: The metaphorical use of the term “bridge” is meant to describe the dynamic relationship between the industry and universities, as the driving forces behind the economic development of the country. It should be noted that the Bridge plan is a trnasformational progress towards tackling the most fundamental issues in the national economy–through a process-oriented and purposeful act of “bridgin Manuscript profile

        One of the basic and important research fields in wireless sensor networks is how to place sensor nodes where by using minimum number of sensor nodes all target points are covered and all sensor nodes are connected to the sink. In this paper, a novel method based on imperialist competitive algorithm is used for solving the mentioned problem. In the proposed method, a colony can immigrate from a weak empire to more powerful empire. The idea of immigration is inspired from human society in which a human can emigrate from a country to another country. The network is supposed to be a three-dimensional grid network and the sensor nodes can be only placed at cross-points of the grids while the target points can be deployed at each point of three-dimensional space. The simulation results show that the proposed method uses fewer number of sensor nodes than other similar algorithms and has the less running time. Manuscript profile

        In the path of economical development for promoting technology levels of a country, different methods of acquisition of technology, improving current technology and also developing and boosting a new technology by localizing and also R&D are used. Although transferring and technology acquisition is considered as an effective tool in developing industries but importing machineries and industrial tools does not just mean acquisition. The appropriate acquisition is accompanied with technical knowledge and the knowledge of how to use it. In this regard, the balance between technology strategy and business strategy is extremely important on the increase of competitive advantage and also to technology adaption in the national level. The aim of this research is to identify correlation of Porter's five strategic factors with technology acquisition modes with respect to cho and you's technology absorption model and also determine the correlation of these factors with the absorption of technology method and finally provide a model to align strategic and technological goals of company. Nonparametric test is used for achieving research purposes. Chi-square test is used to determine the independence or correlation between independent variables and the dependent variable, and Kendall tau b is used to determine the homogeneity of the criteria. Based on the results, the alternative of buyers bargaining power has the highest correlation with technology acquisition methods. Manuscript profile

        In the current study, identification and analysis of the factors affecting the electronic signature effect on the prosperity of the job area between the institutions (case study: oil industry) had been studied.In this study, in order to analyze the resulted data, the descriptive and deductive statistical methods have been used, and the SPSS Software is used in this regard. For choosing the test of the hypotheses, first, the data normality test (Kolmogrov-Smirnov) was used for the calculation. The results of the normality test showed that there is no condition for the equality of the variances and the data are not normal. Therefore, in order to perform the test, the non-parametric tests were used, because the conditions related to the parametric tests were not available. For performing the test of the mean difference between the education and using the digital (electronic) signature, regarding the fact that the education level was in the form of categories, and it was higher than two categories, the one-way variance analysis test was used. To compare the means with each other and to determine the level of the meaningfulness of the differences, Tookie Test was used. Regarding the point that all the persons are inside two categories from the viewpoint of the job backgrounds, the T-Test of the independent groups is used in order to review the job backgrounds of the people. Eventually, the final result of the test of the hypotheses showed that considering all the variables, excluding verifying the identity and being undeniable in the process of job units, the effect of utilizing the electronic signature in juicing up the job in two institutes is too much, and the effect of these two ingredients is lower than the average.

        Increasing the dimension of the databases have involved the attribute reduction as a critical issue in data mining that it searches to find a subset of attributes with the most effectiveness on the hidden patterns. In the current years, the rough set theory has been considered by researchers as one of the most effective and efficient tools to the reduction. In this paper, the soccer league competition algorithm is modified and adopted to solve the attribute reduction problem for the first time. The ability to escape the local optimal, the ability to use the information distributed by players in the search space, the rapid convergence to the optimal solutions, and the low algorithm’s parameters were the motivation of considering the algorithm in the current research. The proposed ideas to modify the algorithm consist of utilizing the total power of fixed and saved players in calculating the power of each team, considering the combination of continuous and discrete structures for each player, proposing a novel discretization method, providing a hydraulic analysis appropriate to the research problem for evaluating each player, designing correction in Imitation and Provocation operators based on the challenges in their original version. The proposed ideas are performed on small, medium and large data sets from UCI and the experimental results are compared with the state-of-the-art algorithms. This comparison shows that the competitive advantages of the proposed algorithm over the investigated algorithms. Manuscript profile

        Permeability is one of the most important petrophysical parameters that play a key role in the discussion of production and development of hydrocarbon fields. In this study, first, the magnetic resonance log in Asmari reservoir was evaluated and permeability was calculated using two conventional methods, free fluid model (Coates) and Schlumberger model or mean T2 (SDR). Then, by constructing a simple model of artificial neural network and also combining it with Imperialist competition optimization (ANN-ICA) and particle swarm (ANN-PSO) algorithms, the permeability was estimated. Finally, the results were compared by comparing the estimated COATES permeability and SDR permeability with the actual value, and the estimation accuracy was compared in terms of total squared error and correlation coefficient. The results of this study showed an increase in the accuracy of permeability estimation using a combination of optimization algorithms with artificial neural network. The results of this method can be used as a powerful method to obtain other petrophysical parameters. Manuscript profile

        prudence and the paris convention Competition has different titles, but fair competition in recruitment make the benefits of a all society. But in some instance, competitor use irrecoverable harm to their compet-ing commercial interests by using illegal and unprotected methods. In this case, it is a type of competition in which business competitors use equipment unfairly and compete for unfair titles. Unfortunately, there is no exact definition of the meaning of unfair competition, but in addition to unfair competition, which is discussed in private law, there is no definite way of defining public rights and economic rights, which they call competition law. In the law of instance such as offensive and discriminatory pricing, monopoly, similarity of name and trademark, as well as cases in the field of industrial property rights, we can mention the obstacles to fair competition, in other words, unfair competition. In Imamieh jurisprudence, with its rich resources, it is prohibited to disor-derly competition, among which, in addition to many verses and narratives, it is possible to mention cases such as hoarding, reckoning, and the rule of lawlessness. Given the above, it is clear that the law defends a fair competition and request to reform the com-petitive relationship between individuals, which, assuming this important, can be seen as a Justice-centered economy. In this study, to clarify the nature of Fair competition , con-cept and examples of unfair competition, and to better understand the unfair competition law, compare it with some of the relevant institutions in the Paris Convention and other conventions.
