Nowadays the urban growth pattern of cities is growing dramatically; and current suburbs of cities will form the inseparable components of the main city in the near future. In all cities of world vertical and horizontal urban growth have been one of the most important factors noticed by urban managers and planners. Urban growth is a spatial - structural process that refers to the increased importance of towns and cities as a concentration of population within a particular economy and society. Increase in urban points as quantitative issue shows itself in the forms of increase in population of cities and development in built up area scale. The unorganized physical growth of cities is due to their physical discrete and separate development which is mostly in form of forming individual and separate parts. Hence, analysis of the current physical status, and prediction of the future development of cities due to its influence on the politics and management of city and human resources, is of great importance. Regarding the numerous factors affecting the inharmonic physical urban growth, the present article has investigated the rate of urban horizontal growth from two aspects of area and direction.The research method in this article is analytical- comparative and with respect to the evolution of the physical- spatial pattern of Tabriz metropolitan in the 1956-2006 period. Shannon’s Entropy model is utilized for evaluation of the rate of the urban horizontal growth diversity. In order to use this model first we draw the complete and detailed plan of Tabriz city in concentric buffers with width of one kilometer between years 1956-2006 using Auto Cad software and the physical gravity center of Tabriz city which is the same center of cultural- historical part has been considered as basis for buffering modulation, and Sectoral- Geographical model is used for specification of urban growth directions. . In the next phase center of city gravity has drawn in the form of circle with determined diameter and the center of this circle was considered as basis for modulation of geographical sectors and sectoral buffering in 12 geographic directions. The attained results of analyzing the research findings has shown that the sprawl growth and diversity of inharmonic development has occurred in Tabriz metropolitan. The maximum of this rate has happened on the year 1996 and directions of horizontal urban growth are completely coincided on the margins of main connection corridors of city.

Discursive semiotic approach with considering the body-centered subject to create meaning and assert an emotional, sensitive-perceptive and aesthetic dimensions can be an appropriate method to analyze and gloss the confessional texts. According to the teachings of this theory, researchers can resist or appease with the “other” by making inter-discourse challenges and create correspondence or different flows, also try to authenticate or reconstruct their identity. The subject of study in Taj-o-Saltaneh’s Memories as a confessional text, gets converted into a gravitational discursive center in order to gain identity and be set free from meaning crisis; so it can play its significant role in interaction and confrontation with other.
Based on the nature of confessional discourse and emotion-oriented positioning of the subject in Taj-o-Saltaneh’s Memories, it is the emotional dimension of discourse which overcomes the action and cognitive dimension of discourse and influences different levels of syntax validity, intensity-extensity relationships and discursive values by supplying power to the narrator to take positions and limits against discursive competitors. According to the point of view and the position of narrator, the otherness process receives different shapes and creates different identical forms for the subject.
The current research aims to answer the question of how the orientation of the enunciator -subject determines its resistance or appeasement against the realm of rival, and how by referring to semiotic components, these attributions can be achieved. The authors suppose that the subject resist the prevailing discourse with intensity-extensity relationships, symbolization, rhythmic thinking and referring to the phenomenological form of the presence, then with a persuasive appeasement, accepts and surrenders herself. The category of space ties with the identity of subject and finds discursive function and include three features: critical, intermediate, and uncritical all being able to find in Taj-o-Saltaneh discourses which guarantees the presence of the subject.

This study is aimed to investigate the effect of microbial Lipase enzymes in different concentration of 10,30 and 50 ppm and ckecking it effect on bugget`s quality. Physicochemical characteristics of bread such as moisture, volume, texture tough, color and intuitive traits are evaluated. The results revealed that there aren`t  any remarkable differences in smell, volume, taste, crust color, shape coordination, crack and rupture and exterior characteristics between experiments and control experiment in intuitive evaluation (P>0.5). Bread produced in 10,30 ppm values of  Lipase enzyme have more prominence  in  characteristics like inner texture , crust quality, improving the ability to br chewed, proper perforation of the texture than control experiment, but using 10 ppm Lipase showed the most prominence in receiving overall intuitive characteristics. According to the results of texture examinations, using10,30ppm concentrations lipase  is better than 50 ppm lipase. Bread produced with 10ppm lipase showed the maximum volume and best crumb color, and 30 ppm lipase enzyme the best crust color of the all, and it has the maximum moisture between experiments and it was a remarkable difference among all experiments (P<0.5).

In this study, feedback-feedforward control system design and optimizing the performance of crude oil furnace process was investigated in order to be recovered from possible abnormal conditions. First, by developing an accurate nonlinear analytical model, the effects of changes in input parameters and operating conditions on the system’s outputs were determined. Then, in order to eliminate the effects of disturbances on furnace, a feedback- feedforward control system for combustion management was suggested, where its performances were optimized genetic algorithm (GA). In addition, to enhance the thermal stability and to maintain product quality, output difference temperature control system was considered for load distribution between furnace’s streams. Also, in order to recover the furnace from abnormal conditions due to burners’ failures, a supervisory system was designed to change the firing rate setpoints. With respect to different failure scenarios, the optimal burners’ firing rate were captured by applying genetic algorithms to the system model. A multilayer perceptron neural network was employed as the core of the controller to interpolate between different conditions. The obtained results indicate the superior performances of the designed control systems.
