Human activity recognition using depth information is an emerging and challenging technology in computer vision due to its considerable attention by many practical applications such as smart home/office system, personal health care and 3D video games. This paper presents a novel framework of 3D human body detection, tracking and recognition from depth video sequences using spatiotemporal featur...

In this work, in order to analyze the load distribution on bolted joints, three different configurations of joints were modeled using the finite element method FEM, varying the joined parts and shim thickness, the intensity of the applied loads and the bolt diameter. All the proposed models are bi-dimensional, modeled with plate elements which present the same inertial moment of the parts in be...

Arthrogryposis as a congenital malformation that refers to the fixed flexion of one or more joints as a result of stiffness or limited movements of multiple joints, change of posture and limb function due to permanent contracture of joints and wasting of muscles that usually occur at early stage of gestation. This report describes congenital arthrogryposis associated with musculoskeletal defect...

In recent years the cultural landscape has become an important issue for cultural heritages throughout the world. It represents the "combined works of nature and of man" designated in Article 1 of the World Heritage Convention. When a landscape has a cultural heritage value, important features should be marked and mapped through the delimitation of a conservation area, which may be essential fo...

Suzhou is one of China's most famous ancient cities. It is a city steeped in history with a rich ancient culture and is famous for its scenic spots, water canals, and its traditional Chinese rock and water gardens. With 35 km of waterways and rivers criss-crossing the city, it is often referred to as the "Venice of the East". Bordering Shanghai on the east, Wuxi City on the west, Zhejiang Provi...

Negotiation of constricted canals can be a challenge during endodontic treatment. Over the years, several strategies have been presented in order to overcome the difficulties imposed by this anatomical feature. This paper presents three cases using a different protocol from that recommended by the manufacturer of the Protaper System in order to facilitate the negotiation of constricted canals. ...

recently a method has been developed to decouple the equations of motion for multi-rigid body systems. in this paper, the method is first studied, then the equations of motion for a planar two degree-of-freedom robot with flexible joints are carried out using lagaranges equations and kanes equation with congruency transformations. finally, the results obtained from both methods are throroughly ...
