The paper begins with a review of the rational for development of personal rapid transit, the reasons it has taken so long to develop, and the process needed to develop it. Next I show how the PRT concept can be derived from a system-significant equation for life-cycle cost per passengermile as the system that minimizes this quantity. In the bulk of the paper I discuss the state-of-theart of a ...

This paper considers how competition can affect aggregate innovative activity through its effects on firms’ decision whether or not to vertically integrate. A moderate increase in competition enhances innovation incentives, too much competition discourages innovative effort. These effects generates an inverted-U relationship between competition and innovation and between competition and the inc...

본 논문은 직교 주파수 분할 다중 반송파 (OFDM; orthogonal frequency division modulation) 시스템의 최대 전력 대 평균 전력 비율 (PAPR; peak to average-power ratio)을 감소하기 위한 톤 예약 기법 (TR; tone reservation)에서 최고 줄임 톤 (PRT; peak reduction tone) 집합을 적응적으로 적용하는 새로운 방법을 제안한다. TR 기법은 PRT 집합의 크기가 커질수록 PAPR 감소성능이 뛰어난 역관계가 존재한다. OFDM신호의 PAPR을 감소시키기 위해서는 높은 톤 비율을 적용해서 많은 톤을 PRT로 선택해서 PAPR을 감소시키면 데이터 전송효율이 떨어진다. 본 논문은 크기가 서로 다른 PRT 집합을 미리 선...

agents are designed to utilize the known methods of machine learning with Bayesian Networks (BN): parameter learning and structure learning. In addition, a new method of machine learning with BNs, termed utility learning in this paper, is introduced. BN software for Matlab is used to realize the proposed agent. Additional software is written to simulate the PRT problem using various intelligent...

There is an increasing interest on recommending to the user instantly (during typing characters) queries and query results. This is evidenced by the emergence of several systems that offer such functionalities (e.g. Google Instant Search, Facebook for social searching, IMDB for movie searching, etc). In this thesis we consider more informative recommendations based on various precomputed aggreg...

We customize here, for the purposes of precomputed and interactive deformation and animation techniques, some basic concepts and deformation methods of differential topology related to Cobordism Theory.

We apply speciication and veriication techniques based on the timed I/O automaton model of Lynch and Vaandrager to a case study in the area of automated transit. The case study models and veriies selected safety properties for automated Personal Rapid Transit (PRT) systems such as PRT 2000 TM , a system currently being developed at Raytheon. Due to their safety critical nature, PRT 2000 TM and ...
