a digital look-up table adaptive predistortion technique using a six-port receiver for power amplifier linearization is presented. the system is designed in ka-band for a dvb-s2 satellite link. we use a six-port receiver at the linearizationloop in place of classic heterodyne receivers. the six-port receiver is implemented by the use of passive microwavecircuits and detector diodes. this approa...

Background: Laparoscopic Surgery (LS) may be associated with many port site complications such as hernia, bleeding, infection, subcutaneous emphysema and ugly scars. Some of these complications are serious such as obstructed port site hernia . Rate of these complications is low depending  on size and site of the port incision, type of the trocar that it is used, the condition of  the patient a...

Port-hinterland transport involves freight gathering and distribution between hinterland economies ports. It is responsible for a major portion of the negative externalities entire port-related logistic chain. This study proposes an integrated model framework to facilitate design modal shift policy mixes increase sustainable performance port-hinterland transport. The consists three parts: (1) e...

In order to enhance the level of green and sustainable development economy, national policy ecological civilization construction is proposed. The 14 coastal ports with top 20 container throughput in China 2020 are taken as research objects, environmental efficiency evaluation index system constructed by combining requirements put forward civilization, three-stage SBM model applied measure from ...

In this paper an unsupervised approach to domain adaptation is presented, which exploits external knowledge sources in order to port a classification model into a new thematic domain. Our approach extracts a new feature set from documents of the target domain, and tries to align the new features to the original ones, by exploiting text relatedness from external knowledge sources, such as WordNe...

External radiotherapy following surgery for breast carcinoma may induce radiation injury to the lungs in a number of patients. Two types of injury are recognized that are temporally related to radiotherapy; an acute pneumonitis-like illness and fibrosis, with abnormalities confined to the radiation port (1). However, the spectrum of radiotherapy-induced sequelae may be more diverse. Two patient...

The aim of the research is to identify and quantify direct economic effects resulting from improved seaport nautical access capacity expansion. This case study considers a regional port located in Baltic sea relates users, i.e., shipping operators shippers. were identified for maritime transport by comparing performance two scenarios: with-the-investment without-the-investment. Incremental calc...
