the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...
Computer graphics matured over many years and played an important role in the development of engineering products like automotive and aircraft components. The current CAX (CAD/CAM/CAE) tools use computer graphics extensively, while helping in conceiving better designs with improved quality. Nowadays, engineering product development is being done concurrently and collaboratively, due to the adva...
growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
having conducted the experiment and analysed the data, the researcher computed the groups mean scores and variances for the test relating to the research question. as the final atep, a t-test was conodonted for the hypothesis. as noted earlier, the significance level was determined at .05 and .01 respectively. the observed t-value was higher than the critical t-value at. 5 and .01 levels. conse...
Who could have imagined a decade ago what an enormous range of possibilities CAD/CAM systems would offer to the dental laboratory of today? The development of equipment and software, and also the materials which can be processed, has advanced at an unexpected rate in recent years. Anyone who as a manufacturer does not “go along with it”, or even worse lets the competition overtake him, has no c...
This paper presents a control model of the hydroforming and the dual hydroforming process of a tube. The theoretical part includes calculations to measure the change in tube thickness through the developed process. The hydroforming and the dual hydroforming processes are simulated in the SOLIDSIMULATION software and the static and the dynamic simulations are modeled. The obtained results for th...
The growing sophistication of applications continually pushes the design and manufacturing of digital systems to new grades of complexity. Computer aided design education deals with the computer as a tool to help perform the various tasks that comprise the design process of digital systems. In order to understand the capabilities of that tool, one has to study how the tool is used in the differ...
