In architecture, there is a relationship between the forms and meanings. Causal relationship between the meaning of each other's perception, and the perception of the form with the designer. This relation resulted in what students' suffer the most throughout their architectural teaching process which is the difficulty of clarifying the relations during design process, i. e., difficulty of clarifying the relation during architectural design process as intellectual ability to generate design ideas; represented by producing highest number of ideas possible of forms related to a certain designing problem.
The method that has been employed the study of the form and meaning and their perceptions, associating form imagination with its meaning and usage nature to achieve association results. Disparity among architectural students has been distinguished through their tested performance on theoretical architectural design activities.
The phenomenon of associating the form with a certain meaning has been linked to achieving figurative usage through demonstrating the placement of form and meaning and their architectural relationship. Versus The actual usage of the meaning fulfills its role of leading receiver's mind to imagine the meaning unconditionally because of the causal language relationship between the form and its meaning is capable of achieving this purpose.

Eleven simple span reinforced self-compacting concrete deep beams were tested under symmetrically two points top load to examine the influence of the transverse circular openings on their behavior. The variables investigated involve shear span to effective ratio a/d, opening sizes and locations and the amount of inclined reinforcement around the openings. All the beams had the same overall dimension, flexural reinforcement and concrete compressive strength. The test results showed that when the opening positioned at the center of the shear span significantly affects the behavior of the beams tested regardless of a/d ratio and size investigated. Also, it was found that when the opening of a large diameter positioned away from the load path either in thetopor bottom region of the beam reduces the cracking and ultimate load considerably. The inclined reinforcement around the opening was observed to be very efficient in improving the ultimate load capacities and deflection response.

Single point incremental forming SPIF is a flexible manufacturing process that does not require a special die for each part and is conducted on CNC milling machine that control on the motion of the forming tool. The formability is very important in any forming process therefore this work is concentrated on the influence of some factors on formability during SPIF. The factors that were studied are: type of tool path, depth step, feed rate and tool rotational speed. Three factors (depth step, feed rate and tool rotational speed) are examined depending on three levels (low, medium and high levels) while the type of the tool path was examined depending on two levels (low and high levels). In this work the total number of experiments is 18 experiments except the screening experiments that were made beforethe main experimental tests. Response surface method is used to build the predictive model to predict the value of effective strain for experiments that are not experimentally conducted. The results show that the feed rate and interaction between step size and type of tool path have the largest effect on formability. It is found that the maximum value of formability in terms of effective strain was (ε ̅=0.5049) while the minimum value was (ε ̅=0.26456). It is also found that SPIF is affected by the friction at the interface between forming tool and sheet metal as in other metal forming processes.
