Speeding is a major cause of traffic accidents and is estimated to be the cause of about 40% of fatalities in road accidents. Speed is a major accident risk factor and affects both rate and severity of traffic accidents. This importance has led to universal use of intelligent control systems for maintaining road safety by enforcing speed regulations. In this study, a modeling is carried out by ...

SOFT HANDOFF MODELING IN CDMA CELLULAR SYSTEMS Jae Kyun Kwon and Dan Keun Sung Department of Electrical Engineering, Korea Advanced Institute of Science and Technology, Korea Abstract|We propose a new analytical soft hando model in a rectangular cell con guration and obtain the probability distribution of the sojourn time in the soft hando region. The movements of a mobile user are categorized ...

1.1 Articular cartilage Articular cartilage is a specialized connective tissue that covers the ends of the bones in the diarthrodial joints. The thickness of human articular cartilage is typically between 1-6 mm. The main functions of articular cartilage are to dissipate and distribute contact stresses during joint loading, and to provide almost frictionless articulation in diarthrodial joints....

A series of poly(ethylene glycol) (PEG)-based segmented block copolymers were synthesized with two structurally different hard segments, linear and heterocyclic aliphatic amines. Ionenes via a modified Menshutkin reaction three weight fractions domains (amine rich segment) soft (PEG oligomers). TGA results show that both DABCO-based ionenes thermally stable up to 250 °C. DSC XRD data indicate i...

OBJECTIVE High-definition transcranial direct current stimulation (HD-tDCS) and high-density electroencephalography require accurate models of current flow for precise targeting and current source reconstruction. At a minimum, such modeling must capture the idiosyncratic anatomy of the brain, cerebrospinal fluid (CSF) and skull for each individual subject. Currently, the process to build such h...

Abstract Polymer semiconductors are promising materials for stretchable, wearable, and implantable devices due to their intrinsic flexibility, facile functionalization, solution processability at low temperatures. However, the crystalline domain of conjugated structure high charge carrier mobility in semiconducting polymers exhibits lower stretchability than that semi‐crystalline or amorphous d...
