Conference Paper
An autonomous car, also known as a robot car, self-driving car, is a vehicle that is capable of sensing its environment and moving with little or no human control. In most cases today, a driver can switch "driving mode" of his/her car between manual and autonomous. However, while the mode can be smartly changed, it is not able to show the current d...

Filtering face-piece respirators are the frequent personal protection devices of hospital’s healthcare workers to decrease infective risk, and its protection level is determined by how well the face-piece fits to the wearer’s face. This study aims to apply 3D scan, programmable modeling, 3D printing technology and bio-compatible filament to realize...

Background Traditional splinting processes are skill dependent and irreversible, and patient satisfaction levels during rehabilitation are invariably lowered by the heavy structure and poor ventilation of splints. To overcome this drawback, use of the 3D-printing technology has been proposed in recent years, and there has been an increase in publi...
Conference Paper
Additive manufacturing, the academic term of 3D-Printing, is the way of fabricating new objects by adding materials layer-by-layer. Our team extended this technology to the next level enabling users to add materials directly onto ready-made (3D-printed) objects. Therefore, we named our technology as 'Additive-Additive-Manufacturing'. While 'Additiv...

Background Applying 3D printing technology for the fabrication of custom-made orthoses provides significant advantages, including increased ventilation and lighter weights. Currently, the design of such orthoses is most often performed in the CAD environment, but creating the orthosis model is a time-consuming process that requires significant CAD...
Article
Our demonstration shows a system that estimates internal body structures from 3D surface models using deep convolutional neural networks trained on CT (computed tomography) images of the human body. To take pictures of structures inside the body, we need to use a CT scanner or an MRI (Magnetic Resonance Imaging) scanner. However, assuming that the...

... The past decade has seen more research on embedding Information and Communications Technology (ICT) systems in everyday objects to promote richer ways of interacting with computers [66]. This means that everyday objects such as chairs [21,63], lamps [1], throw cushions [76,87] and tabletop surfaces [3,19] can now serve a dual purpose; primarily in the role they traditionally have been associated with (e.g. a chair for sitting) and alternatively as input and output interfaces in smart home contexts (e.g. a chair as a ubiquitous input device for interaction with a desktop computer [64]). While many of these technical interventions are yet to be fully refined, it is evident that the smart home field is slowly approaching the levels of calm computing as envisioned by Weiser et al. [82], where interactive surfaces will eventually blend in with the surroundings, may not be visibly distinguishable, and would become active when needed. ...
... This was done with inspiration from deimatic behavior 2 as observed in the natural world -where animals can show pacifistic or agonistic disposition (friendly or threatening attitude) by changing the shape of their body, fur, spines, or feathers in accordance with aggressive or submissive attitudes. Another concept by Eguchi et al. [10] uses inflation and deflation to indicate one of three modes: manual driving, automated driving/ platooning, and yielding to a pedestrian. ...
... Ancak aynı seviyede bariyer koruması, sıvı direnci, filtrasyon ve enfeksiyon kontrolü sağlayamayabilirler. 3B baskı teknoloji ile koruyucu ekipmanların yenilikçi tasarımları herhangi bir düzenleyici kurum tarafından onaylanmamıştır ve performanstan ödün verilmiş olabilir. Ancak düşük maliyetli, hızlı ve merkezi olmayan ve dağıtılmış üretim sağladıkları için, 3B baskılı maskeler acil durumlarda yardımcı olarak görülür [15,16]. Örneğin; Ford, 3M ve General Motors'un birlikte COVID-19 hastalığı olan koronavirüse karşı koruyucu yüz maskesi teknik özelliklerini içinde barındıran 3B baskılı yüz kalkanları üretmektedir [17]. ...
... The use of additive manufacturing in medicine can be applied in various elds, ranging from surgical planning in traumatology or urology[8-10] to the creation of orthoses or splints [11] or even to tissue engineering and regenerative medicine [12]. Personalized treatment can be easily achieved due to additive manufacturing that allows the creation of devices designed by assisted design [1]. ...
... In literature, different approaches can be found, which subdivide AM systems regarding their construction. In the following, the differentiation of 3D printers into four system types is used ( Figure 1) [9]: ...
... Li et al., in their study, created parametric models of orthosis using the Visual Programming Language in the CAD environment [42]. Five students from a nursing school participated in a brief training program (~15 min). ...
... It is also being used for hospital inventory management. It keeps track of all the things used and provides timely information about required equipment [34][35][36][37]. ...
