air spindles are one of the main elements of precise machine tools. vibration of these spindles is one of the vital issues necessary for investigation. among parameters which influence air spindle vibrations are rotational speed, compression air method, input nozzle diameter, air gap pressure. in this study using ansys, the effects of air gap thickness on air spindle vibrations have been invest...
precision forging process is widely used for the production of spur gears due to its advantages such asimproved strength and surface finish, little waste of materials and reduction in the machining time ofthe gear. an important aspect of precision forging process is the load required to perform the processsuccessfully and design the forging tools. in this research, a new kinematically admissibl...
Background: A precision health care approach is needed in the context of the healthcare system, especially as an effort to improve the self-management activities of diabetes patients. Thus, the purpose of this study was to explore the perception of the possibility of implementing a precision health care program in hospitals through interviews with policymakers and health professionals. Methods...
As one of the key methods to extract content semantics and structure from audio, automatic audio classification, especially for a speech and a music, is valuable for content-based audio retrieval, video summary and retrieval, and spoken document retrieval, etc. Because hidden Markov model (HMM) can well model audio signal’s time statistical properties, a left-right discrete HMM is proposed to c...
Background: Precision medicine is a new approach in the field of medical sciences that utilizes the genetic characteristics of each patient along with clinical information to guide decisions related to diagnosis and early treatment of diseases. The Personalized Medicine Research Center, as the only center approved by the Ministry of Health, is working on precision medicine context and producing...
