one of the main requirements for providing software security is the enforcement of access control policies, which is sometimes referred to as the heart of security. the main purpose of access control policies is to protect resources of the system against unauthorized accesses. any error in the implementation of access control policies may lead to undesirable outcomes. hence, we should ensure th...

The AGV (automated guided vehicle) was introduced in UK in 1953 for transporting. But nowadays, due to their high efficiency, flexibility, reliability, safety and system scalability, they are used in various application in industries. In brief, the AGV robot is a system which typically made up of vehicle chassis, embedded controller, motors, drivers, navigation and collision avoidance sensors, ...

background and aim: otoacoustic emissions (oae) and automated auditory brainstem response (aabr) are the most commonly-used methods for universal neonatal hearing screening (unhs). various sensitivity and specificity rates have been reported for the oae and aabr tests as tools for screening newborn hearing. the main objective of this review was to determine the pooled sensitivity and pooled spe...

purpose: to investigate the biomechanical features of transplanted corneas after penetrating keratoplasty (pk), deep anterior lamellar keratoplasty (dalk), and descemet stripping automated endothelial keratoplasty (dsaek) and compare these measurements with those of a normal group. methods: forty-five eyes of 36 patients underwent pk, 23 eyes of 21 patients received dalk using anwar’s big bubbl...

Security is a vital issue in the usage of Automated Teller Machine (ATM) for cash, cashless and many off the counter banking transactions. Weaknesses in the use of ATM machine could not only lead to loss of customer’s data confidentiality and integrity but also breach in the verification of user’s authentication. Several challenges are associated with the use of ATM smart card such as: card clo...

Introduction: It is recommended that the physician apply at least a semi-quantitative segmental scoring system in myocardial perfusion SPECT.  We aimed to assess the agreement between automated semi-quantitative analysis using QPS (quantitative Perfusion SPECT) software and visual approach for calculation of summed stress  score (SSS), summed rest score (SRS) and summed difference score (SDS). ...

Although construction has been known as a highly complex application field for autonomous robotic systems, recent advances in this field offer great hope for using robotic capabilities to develop automated construction. Today, space research agencies seek to build infrastructures without human intervention, and construction companies look to robots with the potential to improve construction qua...

One of the main requirements for providing software security is the enforcement of access control policies which aim to protect resources of the system against unauthorized accesses. Any error in the implementation of such policies may lead to undesirable outcomes. For testing the implementation of access control policies, it is preferred to use automated methods which are faster and more relia...

agent-based negotiation is one of the interesting approaches in the field of automated negotiation in the e-commerce world. establishment an automated negotiation needs to develop a mechanism for it and it is obvious that users would accept a mechanism that is reliable alternative for negotiating individual. therefore, the need to developing efficient and reliable agent-based negotiation mechan...

purpose: to evaluate the visual and refractive outcomes of automated lamellar therapeutic keratoplasty (altk) in patients with keratoconus. methods: in this prospective noncomparative clinical trial, altk was performed in 14 eyes of 14 patients with moderate to severe keratoconus. all patients were spectacle and contact lens intolerant.  uncorrected visual acuity (ucva), best corrected visual a...
