The type of filter affects value of roundness error. There were many studies that explain the differences between filters theoretically and few of them have studied the differences practically. This study aims at introducing a practical comparison of the following filters (2CR50, 2CR75, 2CRPC50, 2CRPC75, Gaussian and no filter) in order to demonstrate the effect of each on roundness error values. RA-120 ROUNDTEST instrument was used for measuring out of roundness of 25 turned workpieces. Least squares reference circle (LSC), minimum zone reference circle (MZC), maximum inscribed reference circle (MIC) and minimum circumscribed reference circle (MCC) methods were used for out of roundness evaluation. The experimental study showed that the filters have a clear effect on the values of the roundness error (RONt) and 2CRPC50, 2CR50 and Gaussian filters give the lowest values of (RONt) compared to others and the relationship between them depends on relation between a sinusoidal wavelength λ and the cut-off in length λc </strong> <strong>. Also from ANOVA analysis the method (LSC, MZC, MIC and MCC) used in RONt evaluation does not affect the relationship between the above-mentioned filters, but rather affects their values</strong>https://bfemu.journals.ekb.eg/article_258989_0c15da5f4fe794d381f02383995c3e02.pdfMansoura University, Faculty of EngineeringMEJ- Mansoura Engineering Journal1110-092347520220927Visual Design and A Role in Improving the Performance of Urban Paths Case Study: Bank Masr Street in Mansoura City132126142710.21608/bfemu.2022.261427ENMarwaAatef Abd ElhadyLecturer at Architectural Engineering Department, Faculty of Engineering, Mansoura University0000-0002-5065-7129AyaTharwat El-sayed AliDemonstrator, Architectural Department, Delta Higher Institute for Engineering and Technology, MansouraJournal Article20220702<strong>Mansoura city includes the largest gathering of the distinctive service activities of the delta region and we find many urban axes, including these health, commercial and educational services, </strong> <strong>Bank Masr street is considered one of the most important urban paths within the heart of the city, so it was chosen as a case study for the research paper and shed light on the elements of urbanism by monitoring the current situation for him and then developing a development proposal in accordance with the foundations of urban design to form a distinctive visual image worthy of the material and moral value of the city of Mansoura.

Therefore, the sustainability of architectural education must be sought in the programs of architecture in Egyptian universities and raise the level of their quality through environmental behavior studies, sustainability and environmental awareness, and digital and virtual practices. Hence, this research evaluates some architectural programs (Mansoura University - Tanta University) using the international verification standards NAAB, RIBA and UIA to determine the extent to which these programs are compatible with them, and the considerations to be considered when seeking international accreditation and achieving sustainability.

In order to generate the RAM, the Delphi technique was adopted to allocate the risks to the appropriate party and to propose the proper risk response as well. The impacts on time, cost, and quality were determined and the top-ranked risks were identified based on the value of their Risk Factor Indices (RFI) values. The major risks were allocated based on Delphi results, 57% to the contractor, 10% to the owner while 33% were shared liability between both. Moreover, the percentages of risk management actions allocated to each risk factor were, the “risk control” represented 33%, and the “contract clause” represented 24%, However, both “avoidance” and “mitigation” represented 19% for each action while the “insurance” represented 5% only of the proposed risk responses.
