3D objects are produced utilizing the additive manufacturing technique with the aid of computer-aided design software. A few of the techniques that are available in 3D printing technology include the Fused Deposition Method (FDM), Selective Laser Sintering (SLS), Multi Jet Fusion (MJF), Stereolithography Laser Printers (SL), and Digital Light Processing (DLP). In this effort, we have focused on the design and production of a 500 x 500 x 520 mm3 3D printer that is reasonably priced. We employ four-axis mechanisms, one of which is an extruder, three of which are x, y, and z. High Impact Polystyrene (HIPS), Acrylonitrile Butadiene Styrene (ABS), and Polylactic Acid (PLA) are just some of the materials used in the FDM technology that we employ. The filament material is heated until melting, then deposited as one layer at a time. The layers are combined together to form a final 3D model. In this paper, Raspberry Pi is integrated with the 3D printer to improve its usability and convenience. Also, using of Raspberry Pi will enhance the overall functionality such as wireless networking, remote control, and using a sophisticated software. Therefore, the Raspberry Pi can be considered the machine's core control system.

Oftentimes, static analysis of a slab supported by vertical uncoupled Winkler springs is frequently utilized in the structural design of shallow foundations. Many structural designers typically simulate the soil beneath the footing and the raft as a collection of springs with stiffness coefficient estimated based on the modulus of subgrade reaction (ks). Therefore, various approaches for determining ks are compared and reviewed in this work . The main objective of this study is to estimate the modulus of subgrade reaction (ks) of the shallow foundation rested on sandy layer adopting three constitutive soil models (Elastic, Mohr-Coulomb and Hardening soil) utilizing 3D Plaxis analysis. Two parametric studies have been implemented (isolated footing and raft) taking into consideration the effects of foundation thickness and soil constitutive model on ks . The results outlined in this paper show that a thicker footing typically has a lower soil subgrade reaction than one that is thinner; and the estimation of ks based on empirical formulas is being convenient in case of isolated footing. On the other side, the distribution of ks is non-uniform through the raft for all adopted soil models analyses. ks (when considering soil plasticity) is lesser than ks estimated using elastic soil analysis. Using non-linear finite element analysis (considering the soil plasticity) is very important to get more accurate ks and do not depend only on the empirical formulas to evaluate ks of the raft .

Promising remote interactive solutions are offered by the RTC wireless multi-channel data gathering systems. In order to identify and analyze data, this study constructs and uses wireless octet channels. Using an Arduino-Uno connected to National Instruments (NI)-LabVIEW, the data analysis and the appropriate control action will be carried out. A straightforward and user-friendly graphical user interface (GUI) has been created and put into use. The ambient parameters are read us-ing passive infrared (PIR) sensors for temperature, pulse, humidity, and motion. The system offers the possibility of high accuracy data measurements, such as those for temperature and humidity, as well as individual measurements of eight parameters at various reading rates. The means values approach is used to collect correct data for the three sensors in the two described scenarios. Additionally, an effective storage method is employed. It keeps time-and date-stamped information that enables cancellation of any subsequent repeated measurements. The system will only save the most recent updates whenever the environmental parameters have changed. This can significantly reduce the amount of memory needed while yet providing an accurate enough representation of the sensor output. As triggering signals for the actuators, quad flags are used. Finally, this system allows for remote monitoring of the collected data using either a computer or a smartphone with a wifi local area network (WLAN) coverage.

The growth of computer-aided tools used to illustrate or represent the results of architectural projects has been outstanding during the past several years. The establishment of technologies is meant to help designers produce architectural shapes swiftly and interactively. During the earliest design stages, architects may build highly complicated geometric forms and make numerous creative choices due to recent advances in computer technology for parametric design. New ideas and theories could be needed to investigate architectural parametric design alternatives within the theoretical framework. The relevance of parametric design in space design exploration in contemporary architecture is theoretically covered in this study. The topic will then be strengthened by looking at a structure that incorporates parametric design, namely the Abu Dhabi Louvre Museum in the United Arab Emir-ates in order to assess the efficiency of parametric modeling and design ideation.

Recent studies showed that most employees occupy “Meaningless Jobs”, due to poor interaction and deprivation of sensing the working outcome of jobs, especially in the design phase of the construction and urbanism project. However, recent studies proved the need for employees’ engagement with different stakeholders to increase productivity and optimize work performance. Although various industries have adopted the Agile Project Management (APM) approach, the Engineering, Pro-curement, and Construction (EPC) industry might not be ready for APM, due to traditional Human Resources Management Systems. Thus, this research aims to identify the need for Agile Methodologies in the EPC industry and to propose APM phi-losophies and methodologies that might fulfill those needs. The methodology is based on two parts. The practical part includes performing a social survey on the design engineers of the EPC to quantify meaningless jobs. The second part includes a comparative analysis of the needs of the EPC industry against Agile adequacies, in addition to analyzing case studies where applying APM was a success in both EPC and Software industries. The analysis is based on reviewing relevant literature and its statistical findings. The research concludes that the majority of the survey subjects occupy a meaningless job. Meanwhile, their needs can be addressed by applying Agile Methodologies, similar to the shift that occurred in the Software industry. Finally, the paper discusses the high affinity and potential of the EPC industry to adopt APM in design phases.

Beam-column connections are one of the most critical components of steel structures. They are responsible for transferring the loads from the beams to the columns, and ensuring that the structure remains stable and strong under all loading conditions. This research investigated numerically using the Finite Element Method (FEM) the effect of blast load on a steel beam-column connection. The beam-column connection consists of an I-beam column with a length of 1500 mm and an I-beam beam with a length of 500 mm. The column and the beam are connected together through a steel plate of thickness 10 mm. The plate is welded to the beam and connected to the columns by 4 ordinary bolts of diameter 16 mm. The Coupled Eulerian-Lagrangian (CEL) modeling technique found in Abaqus/CAE was used to perform the analysis. Lagrangian elements were used to simulate the steel elements and bolts. The Eulerian elements were used to model Trinitrotoluene (TNT) and the surrounding air. A parametric study has been performed for the beam-column connection. The TNT charges were placed at a standoff distance from the center front of the connection on the same level as the bottom surface of the column. TNT charges of 10 kg, 50 kg, and 1000 kg with standoff distances of 2.5 m, and 5 m have been used in the analysis. Analysis has been performed to study the deformation, stresses, and damage of the connection. The results showed that blast load has a major impact on steel bolted beam-column connections as they could destroy the connecting bolts or even completely destroy the connection. Also, TNT charges of less than 10 kg and a standoff distance of more than 5 m have a minor effect on steel bolted beam-column connection. While, TNT charges of more than 1000 kg and a stand-off distance of less than 5 m cause a catastrophic damage and could completely destroy steel bolted beam-column connection. Moreover, the connecting bolts are the weakest link in steel bolted beam-column connections subjected to blast load as they could be damaged even when subjected to small TNT charges.

A three-dimensional computational fluid dynamics simulation for a micro-scale pump has been performed to investigate the sensitivity of the flow rate to frequency change during pump and supply phases. Applying dynamic mesh under different diaphragm actuation frequencies ( 8, 50, 100, 200, and 500 Hz ) and sinusoidal oscillation amplitude of 6.0 µm the results showed that at frequency f ≥ 100 Hz the flow separation has been formed in the diffuser direction for both supply and pump phases. At low frequency f ≤ 50 Hz there is no flow separation in the diffuser or the nozzle direction. The large recirculation zone is created at the dif-fuser bottom wall side. The flow separation was found to be frequency and direction dependent for the micro-diffuser half angle of 5o . The net flow rate increased linearly with the frequency while the net flow per cycle was less sensitive to the change of the frequency.
我们对微型泵进行了三维计算流体动力学模拟，以研究在泵和供给阶段流量对频率变化的敏感性。在不同的膜片驱动频率（8、50、100、200 和 500 Hz）和 6.0 µm 的正弦振幅下应用动态网格，结果表明，在频率 f ≥ 100 Hz 时，供气和泵阶段在扩散器方向都形成了流动分离。在低频 f ≤ 50 Hz 时，扩散器或喷嘴方向没有流动分离。大的再循环区在扩散器底壁一侧形成。在微扩散器半角为 5o 时，流动分离与频率和方向有关。净流量随频率线性增加，而每周期净流量对频率变化的敏感度较低。

Applying dynamic mesh under different diaphragm actuation frequencies ( 8, 50, 100, 200, and 500 Hz ) and sinusoidal oscillation amplitude of 6.0 µm the results showed that at frequency f ≥ 100 Hz the flow separation has been formed in the diffuser direction for both supply and pump phases. At low frequency f ≤ 50 Hz there is no flow separation in the diffuser or the nozzle direction. The large recirculation zone is created at the dif-fuser bottom wall side. The flow separation was found to be frequency and direction dependent for the micro-diffuser half angle of 5o . The net flow rate increased linearly with the frequency while the net flow per cycle was less sensitive to the change of the frequency.","PeriodicalId":267155,"journal":{"name":"Fayoum University Journal of Engineering","volume":"206 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140281984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
