Fabric Defect Classification Using Combination of Deep Learning and Machine Learning

Fatma Günseli YAŞAR ÇIKLAÇANDIR

Automatic systems can be used in many areas, such as the production stage in factories, country defense, and traffic control. They provide the opportunity to reach results faster with higher success rates thanks to human-computer vision cooperation. In this study, it is aimed to develop an intelligent system that automatically detects and classifies defects in fabrics. Thanks to the developed system, the cause of the malfunction is eliminated, and the recurrence of the malfunction is prevented. Using deep learning methods in fabric defect classification studies has a disadvantage compared to o ...Daha fazlası

Elif Yüzer

Kolorimetrik analiz, biyomoleküllerin saptanmasında kullanılan ve çıplak gözle gözlemlenen maddenin varlığını ve konsantrasyonunu belirlemek için renk değişimlerini kullanılarak ölçülmesini sağlayan bir tekniktir. Sağlık, gıda, ilaç, kozmetik ve boya endüstrileri gibi birçok farklı alanda biyolojik, tıbbi ve çevresel numunelerin analizinde kolorimetrik analiz kullanılmaktadır. Bakım-noktası (POC) testleri kullanım kolaylığı ve ulaşılabilirliği nedeniyle bir çok alanda kullanılmaktadır. POC testlerinin kolorimetrik analiz ile entegrasyonu kullanım kolaylığını arttırmaktadır. Kolorimetrik ...Daha fazlası

The impacts of governance on tourism: a macro perspective Yönetişimin turizm üzerindeki etkileri: makro bir perspektif

Can, Yağmur

ABSTRACTIn this study, the effects of world governance indicators on tourism were empirically analysed, from the 2005 to 2018 period. A literature review for governance is included in the first part. The second part contains the definition of world governance indicators (WGI). In the last part, panel co-integration, and causality analysis have been carried out worldwide within 137 countries. As a result of the analysis, a long-run relationship was found only between the change in the number of tourists and the political stability - no violence index. Also, other world governance indexes voice ...Daha fazlası

Tourist harassment and its impact on tourism experience in Istanbul İstanbul’da turist tacizi ve tacizin turizm deneyimine etkisi

Çetinkaya, Mehmet Yavuz

The tourism industry is referred to as the world’s one of the largest serviceindustries and as one way to achieve development in tourism destinations across the globe and offering benefits and contributing to the local economy for any country. Tourism, which becomes a common phenomenon and important for a wide range of reasons, particularly for the developing countries is one very sensitive and fragile industry to any negativity by its nature. In the global economy, the share of the tourismindustry is increasing and thus, intensifying competition among the growing number of tourism destination ...Daha fazlası

Development of an effective kinematic synthesis and admittance control methodology for rehabilitation robotics Robotik rehabilitasyon için etkili bir kinematik sentez ve admitans kontrol yönteminin geliştirilmesi

Koçak, Mertcan

ABSTRACTThroughout the human life, neurological disorders can occur in body areas due to accidents or other biological factors, which negatively affects human life by destroying nerve commands. In these scenarios, continuous and efficient exercises that focus on injured extremities have great benefits in regaining functional losses by retraining motor movements. Rehabilitation procedures need to be applied quickly in order to create neural plasticity and regain affected motor functions. Although theseactions are mostly performed by therapists in current rehabilitation procedures, robotic rehab ...Daha fazlası

Mandibular asymmetry in unilateral and bilateral posterior crossbite patients using cone-beam computed tomography

İLKNUR VELİ

Objective: To test the hypotheses that (1) there is no difference in mandibular asymmetry between the crossbite and normal side in a unilateral crossbite group (UCG) and between the right and left sides in a bilateral crossbite group (BCG) and a control group (CG); and (2) there is no significant difference in mandibular asymmetry among crossbite groups and control group. Materials and Methods: The cone-beam computed tomography scans of three groups were studied: (1) 15 patients (6 male, 9 female; mean age: 13.51 6 2.03 years) with unilateral posterior crossbite; (2) 15 patients (8 male, ...Daha fazlası

Musculoskeletal Problems in Wheelchair Users: A Review Study

Mobility is the basic need for functionality in human life. Physically disabled people often require mobility aids and wheelchairs are the most commonly preferred assistive mobility devices for enhancing independent functional mobility. Today, powered and manual wheelchair technology is available. Manual wheelchair propulsion necessitates more repetitive loading, but because the human body is not designed for such movement, musculoskeletal and functional issues such as pain and joint limitation may arise among manual wheelchair users. They require more support from their spine, arm, elbow, and ...Daha fazlası
