Topology control protocols try to decrease average of node’s transition radius without decreasing network connectivity. In this paper, we propose a new Artificial Immune System-based topology control protocol for wireless sensor networks named AISTC. In this protocol, proper transition radius can be determined using Artificial Immune System algorithm. This protocol is simulated and compared its...

BACKGROUND Open reduction and internal fixation using an interlocking plate system has gained popularity for the treatment of dorsally displaced distal radius fractures. PURPOSE To evaluate the functional and radiological results of treating unstable distal radius fractures with the volar locking plate. PATIENTS AND METHODS A retrospective review was conducted of patients from one instituti...

In this paper, mathematical analysis supported by computer simulation is used to study cellular system information capacity change due to propagation loss and system parameters (such as path loss exponent, shadowing and antenna height) at microwave carrier frequencies greater than 2 GHz and smaller cell size radius. An improved co-channel interference model, which includes the second tier co-ch...

The RADIUS Common Development Environment (RCDE) pulls together many diverse functions into an integrated whole. The main goal of the environment is to provide a system to carry out interactive cartographic modeling of three-dimensional scenes from multiple images, as well as to provide an infrastructure to support the research in, and implementation of, image-understanding-based algorithms for...

An absolute hydrophone calibration technique using ultrasonic far-field with optical interferometry was extended to 40MHz to evaluate the sound pressure amplitude generated by medical ultrasound equipment. A 1-mm nominal radius plane transducer was the calibration sound source for an ultrasonic far-field at 50mm propagation distance at 40MHz. The transducer’s effective radius was 0.88mm at 40MH...

this paper deals with the threshold radius that warrants the use of single restraining rail for transit and railroads. different railways use different threshold radius from 91m to 365m to provide restraining rail. these threshold figures are probably experience driven choices. the need for restraining rail may be related to a so-called derailment alarm coefficient of 1.2 sustained over 2m leng...

introduction: in recent years spatial justice has gained special importance among planners and geographers. since the urban public services form the structure, shape and the nature of the physical, social and urban space, inequities in their distribution cause irreversible negative effects on the structure and the nature of city and social segregation of the people, and serious challenges in th...

Teriparatide significantly increases bone mineral density (BMD) of the lumbar vertebrae and femur and has a strong effect in reducing the risk of bone fractures. However, few detailed investigations with dual-energy X-ray absorptiometry (DXA) of the effects of teriparatide on the radius have been reported; specifically, there are no reports of the use of once-weekly teriparatide. In this study,...
