Introduction: The aim of this study was to investigate whether there is any relationship between the condition of complete dentures and TMDs. Methods: The sample consisted of 61 consecutive patients (35 females and 26 males) who were admitted to the Department of Prosthodontics of Mashhad Faculty of Dentistry for fabrication of new complete dentures.  The age range of the participants was betwe...

abstractâ cultural norms state human-nature interaction by affecting individual and group values system. ethical norms are the most important ones in which nature and its components become evaluated based on ethical views. there are different ethical normative views toward human-nature interaction. they have been currently categorized into three types of anthropocentric, bio centric and eco cen...

“Terrorists don’t think and move the way armies do. In Afghanistan they learned to hide when they suspected American Bombers were targeting them. To defeat groups like alQaeda, you have to attack as soon as you find them. With speed you can deny sanctuary to terrorists. In Afghanistan the Pentagon was able to reduce that time (the kill chain) to less than 10 minutes. But in those several minute...

As complex autonomous systems become increasingly ubiquitous, their deployment and integration into our daily lives will a significant endeavor. Human–machine trust relationship is now acknowledged as one of the primary aspects that characterize successful integration. In context human–machine interaction (HMI), proper use machines depends both on human machine counterparts. On hand, it how wel...

This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...

Implementing transformational change towards the Net-Centric Operations (NCO) vision in support of enhanced command and control presents technical, operational, and cultural challenges. The technical challenges are being addressed by both industry and the Department of Defense pushing the state of the art further ahead. However, in many cases the technology transformation is too far ahead of th...
