In this study, it is presented a new hybrid model based on deep neural networks to predict the direction and magnitude of the Forex market movement in the short term. The overall model presented is based on the scalping strategy and is provided for high frequency transactions. The proposed hybrid model is based on a combination of three models based on deep neural networks. The first model is a deep neural network with a multi-input structure consisting of a combination of Long Short Term Memory layers. The second model is a deep neural network with a multi-input structure made of a combination of one-dimensional Convolutional Neural network layers. The third model has a simpler structure and is a multi-input model of the Multi-Layer Perceptron layers. The overall model was also a model based on the majority vote of three top models. This study showed that models based on Long Short-Term Memory layers provided better results than the other models and even hybrid models with more than 70% accurate.

The main purpose of this study was to investigate the effect of cultural components on organizational performance in startups. For this purpose, by literature reviewing and theoretical foundations which were derived from independent and dependent variables, the research model was designed. The independent variable of research included cultural components including the dimensions of diversity and breadth, trust and messaging and dependent variable of research included organizational performance in startups. According to the designed model, a questionnaire was distributed among the statistical sample that included all managers of startups in Tehran City. In this regard, 168 questionnaires were distributed by simple random sampling method and by collecting it, the data were analyzed using the structural equation modeling and Amos software. According to the results, all research hypotheses in line with the impact of organizational culture on the dimensions of diversity and breadth, trust and easy communication in startups on organizational performance in startups were confirmed. Also, according to the analysis of the relationship between independent and dependent indices, the variables of messaging, diversity, breadth and trust dimensions showed the highest relationship with 0. 86, 0. 83 and 0. 82, respectively.
