BACKGROUND Alerts in the cockpit must be robust, difficult to ignore, and easily recognized. Tactile alerts can provide means to direct the pilot's attention in the already visual-auditory overloaded cockpit environment. OBJECTIVE This research examined the thigh as a placement for vibrotactile display in the cockpit. The authors (a) report initial findings concerning the loci and properties ...

OBJECTIVES Interest in bone graft material has increased with regard to restoration in cases of bone defect around the implant. Autogenous tooth bone graft material was developed and commercialized in 2008. In this study, we evaluated the results of vertical and horizontal ridge augmentation with autogenous tooth bone graft material. MATERIALS AND METHODS This study targeted patients who had ...

Arboreal substrates differ not only in diameter, but also in continuity and orientation. To gain more insight into the dynamics of small-branch locomotion in tetrapods we studied the veiled chameleon walking on inclined and declined perches of up to 60 deg slope. We found that forelimbs and hindlimbs contribute equally to the body's progression along inclines and declines. The higher-positioned...

The management of facial defects has rapidly changed in the last decade. Functional and esthetic requirements have steadily increased along with the refinements of surgery. In the case of advanced atrophy or jaw defects, extensive horizontal and vertical bone augmentation is often unavoidable to enable patients to be fitted with implants. Loss of vertical alveolar bone height is the most common...

In this paper, a new relay system that uses the UAV as station between tethered and ground user (TU2U2G) is proposed. The TU2U2G TUAV viable alternative to replace BS provide seamless service over cable simultaneously supplies stable power reliable wired data-link connection from control station. Compared BS, improves coverage due its high altitude. Also, it overcomes antenna down-tilting, whic...

adequate coverage is one of the main problems for distributed wireless sensor networks and the effectiveness of that highly depends on the sensor deployment scheme. given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage and save power of sensors for movement to target location to adequate coverage. in this paper, we apply fuzzy logic system to...

BACKGROUND Insufficient bone volume often hamper placement of dental implants in the posterior maxilla. PURPOSE The aim of the present clinical study was to evaluate retrospectively the clinical outcome of implant placement in the resorbed posterior maxilla using an osteotome technique without adding any grafting material. MATERIALS AND METHODS Twenty patients with 5 to 9 mm of residual alv...

BACKGROUND Proper implant placement is very important for long-term implant stability. Recently, numerous biomechanical studies have been conducted to clarify the relationship between implant placement and peri-implant stress. The placement of multiple implants in the edentulous posterior mandible has been studied by geometric analysis, three-dimensional finite element analysis (FEA), model exp...
