As regards the significant role of stethoscopes in the diagnosis of congenital and adventitious heart diseases and prevention of irreparable complications of these diseases, the quality of hearing sound of these stethoscopes by a physician has a significant impact on the disease diagnosis. This device plays an important role in the early diagnosis of congenital heart and respiratory diseases an...
Introduction: A variety of (deliberate or inaccurate) errors in drug rehabilitation clinics may occur due to use of addictive drugs. Automated drug distribution systems play a significant role in reducing drug medication errors. Method: Firstly, according to the addiction rehabilitation centers requests, the design and construction of the device was performed. The prototype systems were examin...
background and objective: obstructive sleep apnea (osa) is a disease with serious consequences. many portable devices have been developed to overwhelm some of limitations in the accessibility of the gold standard test for osa, polysomnography (psg). this study aimed to determine diagnostic accuracy of a portable sleep apnea screener against psg in patients of a sleep clinic. materials and metho...
Introduction: Essure® device malposition is a rare, but clinically significant complication, for which management is idiosyncratic. This case report describes an unusual example of Essure® migration in order to clarify reasonable management options. Case Presentation: A 50-year old G4P2022 underwent hysteroscopi...
In this paper the effects of transmittance, dispersion angle and diffusion length on the quantum efficiency of solar cells (QESC) have been simulated and investigated. Optical path technic is used for simulation. The results show that base thickness, diffusion length, dispersion angle, number of optical confinement path and transmission angles have an extremely effects on the QESC. Simulation r...
In the present work, the effects of different casting parameters including pouring temperature and cooling rate on stainless steel structures and mechanical properties of heat resistant alloy (HH) were studied. Mo nanoparticles were synthesized through sol-gel method and were coated on the stainless steel device using spin-coating method. The effect of coating layer on the device was studied by...

This paper studies requirements for achieving personal trusted devices. Such devices can be for example smart cards or personal digital assistants. We consider both hardware and operating system security. Together they ensure that the device is trustworthy and is able to protect it’s user’s electronic identity (his private key) and data. We study some security problems with smart cards, and giv...
This paper proposes a method whereby a device can transmit and receive information using a beacon, and also describes application scenarios for the proposed method. In a multi-device to multi-device (MD2MD) content-centric networking (CCN) environment, the main issue involves searching for and connecting to nearby devices. However, if a device can’t find another device that satisfies its requir...
