최근 스마트폰 사용자의 폭발적 증가에 따른 모바일 인터 넷 서비스 및 멀티미디어에 대한 급격한 수요 증가로 인해 기 존 3G 망이 포화 상태에 이르게 되었고, 이러한 수요를 만족 시키기 위해 4세대 이동 통신 시스템인 LTE (Long-term evolution) 서비스가 개시되었다. 더불어, 현재 LTE 보다 개 선된 LTE-Advanced 시스템에 대한 연구, 표준화, 개발이 활 발히 진행 중에 있다 [1]. LTE-Advanced의 요구 성능은 하향 링크와 상향 링크에서 최대 데이터 전송 속도가 각각 1Gbps와 500Mbps이며, 주파수 전송 효율 역시 하향 링크에서 최대 30 bps/Hz에 이른다. 이와 같이 매우 높은 데이터 전송률과 주파 수 효율을 얻기 위해, LTE-Advanced에 채택...

The Apollo 14 rocks returned to ear th a re divisible into two broad groups: relatively hoinogeneous crystalline rocks and fragmental rocks (breccias). The crystalline rocks are, for the most par t , metaclastic, but a few, including the second largest sample returned, a re aphyric basalts. All of the crystalline rocks a re considered to be clasts dislodged from fragmental rocks. These fragment...

Shape complexity algorithms are mostly based on information theory, which is based on probability theory and statistics, like Shannon’s definition of entropy or mutual information. The input of the probability density function (pdf), which is a part of the entropy function, could be the curvatures of the 3D shape or other numbered features representing the shape. After applying statistical algo...

The mirin contribution of this report is the development of novel algorithms {that make efficient use of the communication system in distributed memory architectures with plrocessing elements interconnected by a hypercube network. These algorithms achieve almost optirr~al overlap of communicatior~ delays by computation, leading to a minimization of communicatioi~ overhead. Rigorous ana1yt:ical ...

By the early 1990s, scientists knew that programmed cell death, or apoptosis, was important for tissue development and homeostasis as well as for cancer progression. Because apoptotic cells activate nucleases to cleave their chromatin, cell death could be followed in vitro by extracting DNA from a population of tissue culture cells and running it out on an agarose gel to look for a characterist...
