This paper tries to demonstrate the constantly variable MEANING of building despite its fixed physical appearance. This diversity of MEANING can be attributed to the social diversity of building users, as well as the change in its functions. The authors employ a semiotic approach to explain the coding system developed in the dialectic relationship between the building as a text AND its users as readers.

Some scholars in the field of semiotics believe that the semiotic square of Greimas, in certain texts, has a mechanical AND solid structure AND does not successfully represent MEANING in a discourse. They believe that the tensive model is a more appropriate approach since it has FLUID AND DYNAMIC applications. However, FLUID AND DYNAMIC deep structure of narrative can be illustrated through “consecutive semiotic square;” in other words, it can be shown through the processes of the MEANING production in a narrative from the primary MEANING to the ultimate MEANING. This study proposes a new model, namely, “semiotic ladder” to analyze narratives in the lyrical genre, to discover their inner AND deep structure MEANINGs, AND to prove the DYNAMIC characteristic of MEANING in the semiotic square. We argue that the process of the semiotic ladder, thanks to consecutive semiotic squares, represents the displacement AND FLUIDity of MEANINGs in narratives AND reject the mechanical AND solid feature of squares. This model is applicable to all narrative forms.

Mixer- settlers are widely used for solvent extraction process in industry. The aims of this project are simulation of FLUID flow AND optimizing the operational conditions of settler in solvent extraction process. Designing AND meshing of settler geometry is done by Gambit software. Then, in order to simulate the FLUID flow, the meshed designed imported to Ansys Fluent software. Simulation results were verified before simulation. Effect of Inlet volumetric on phase separation investigated. The effect of geometry of picket fences was investigated by the presence of cubic, cylindrical picket fences, picket fences with 5 corner cross section AND half cylindrical picket fences. A few extra plates of picket fences were located near the entrance of settler. Phase separation in presence of two AND three rows of picket fences investigated. Results indicate that by reducing the inlet volumetric rate, increasing the number of rows, putting extra plates of picket fences in front of entrance AND decreasing the closed to open surface ratio to 2, separation improves.

Considering the fact that the words in the intra-religious attitude are considered in two ways, the first is towards jurisprudential words AND the second is a rational AND conceptual view focusing on their MEANINGs. we have tried to deal with one of the most important issues of intra-religious attitude with a rational approach by descriptive AND analytical method, which is the category of "hermeneutic interpretation" of words, especially the most influential idea of interpretation & that is the view of the "spirit of MEANING" of Ghazali. After Ghazali, Ibn Arabi used this theory of Ghazali regarding the development of MEANING in creating his new idea, AND by re-reading Ghazali's idea with a mystical approach, he presented his own theory regarding the expansion of MEANING. While accepting the argument of the focal point of the theory of the spirit of MEANING, he removes it from the exclusivity to the "linear", AND for this purpose, he brought up arguments as well as the Conditions of Hermeneutic Interpretation in this regard. Ibn Arabi's arguments on transversal interpretation include new formulations in the argument, which after him, this theory was favored AND accepted by Mulla Sadra, AND then it was accepted by his students.

Many diseases are related to cerebrospinal FLUID (CSF) hydroDYNAMICs. Therefore, understANDing the hydroDYNAMICs of CSF flow AND intracranial pressure is helpful for obtaining deeper knowledge of pathological processes AND providing better treatments. Furthermore, engineering a reliable computational method is promising approach for fabricating in vitro models which is essential for inventing generic medicines.A FLUID-Solid Interaction (FSI) model was constructed to simulate CSF flow. An important problem in modeling the CSF flow is the diastolic back flow. In this article, using both rigid AND flexible conditions for ventricular system allowed us to evaluate the effect of surrounding brain tissue. Our model assumed an elastic wall for the ventricles AND a pulsatile CSF input as its boundary conditions. A comparison of the results AND the experimental data was done. The flexible model gave better results because it could reproduce the diastolic back flow mentioned in clinical research studies. The previous rigid models have ignored the brain parenchyma interaction with CSF AND so had not reported the back flow during the diastolic time. In this computational FLUID DYNAMIC (CFD) analysis, the CSF pressure AND flow velocity in different areas were concordant with the experimental data.

HydroDYNAMIC coefficients for an autonomous underwater vehicle (AUV) are obtained by simulating the maneuver tests in computational FLUID DYNAMIC (CFD) media. The simulations are performed for different length to diameter ratios by STAR-CCM+ software. Also the effects of different hydroplanes as a hull appendage is investigated. HydroDYNAMIC forces AND moment are computed AND by using suitable curve fitting linear AND nonlinear hydroDYNAMIC coefficients are calculated. The results show that by increasing the length to diameter ratio the higher hydroDYNAMIC coefficients can be obtained. The comparison of simulated results with the available experimental data shows a very good agreement among them.

In this research, based on nonlocal elasticity theory, static AND DYNAMIC analysis of an elastic homogeneous nanotube conveying FLUID with clamped - clamped boundary conditions is investigated.The nanotube is under electrostatic actuation AND magnetic field with considering the surface effects, mechanical AND thermal force. Transverse displacement of the nanotube consists of two parts static AND DYNAMIC displacement. In this study, the static displacement is calculated by using the weighted residual method AND instability AND vibration frequency is analyzed by applying the generalized differential quadrature method. By applying a voltage greater than the critical value (called Pull-in voltage) the nanotube may undergo instability. In this investigation, the effect of various parameters such as velocity of FLUID, length scale parameter, magnetic field, electrostatically voltage, effects of surface layer AND thermal loading on the static displacements, natural frequency AND Pull - in voltage of the nanotubes conveying FLUID has been studied. Finally, the validity of the results by comparing them with the results of the numerical methods in previous research is investigated, in which there is very good agreement between the results of the present work AND previous studies. The results show that the length scale parameter is significant parameter in the system's Pull - in voltage AND its increasing lead to decreasing the Pull-in voltage. Also, it is shown that the dimensionless frequency AND the static displacements, respectively, is decreased AND increased with increases in the applied voltage.

Explaining the MEANING of “Clear Arabic Language” (Arabic: لسان عربیّ مبین) in the Holy Quran according to the opinions of the commentators (the scholars who interpret the Holy Book of Quran) AND the semantic functions of the words is the main issue of this research. Differences of opinion of commentators (Arabic: مفسّر; plural: Arabic: مفسّرون, Romanized: mufassirūn) AND citing their views for different reasons necessitated this research. The present article has been studied AND evaluated the opinions of the commentators in interpreting the verse AND considers their views about “Clear Arabic Language” (Arabic: لسان عربیّ مبین) in four parts. These include: Taḥaddī (Arabic: تحدّی, The Quranic Challenge), the language of the audience AND the place of revelation, the honor AND capacities of the Arabic language, the eloquence AND explicitness of the specific language of the Qur'an. The results of the research show that the “Clear Arabic Language” beyond the opinions of the commentators is a common understANDing that has revealed the superhuman language of revelation through human conversational style AND considered the universal characteristics, transhumanism, transhistorical of the Holy Book of Quran while considering the conditions AND understANDing of the audience. Paying attention to the Quranic MEANING of related words AND narrations as well as Saussure’s linguistic point of view can confirm the recent MEANING.
