In the market of wireless communication, high data-rate transmission and high spectral efficiency have been the trend. The IEEE 802.11 a/g standards working at 5GHz/2.4GHz ISM bands can support data rate up to 54Mbits/s using OFDM modulation. The newly proposed 802.11n technology now uses 64-QAM to achieve higher spectral efficiency. The DVB and many other systems will also use QAM for its data transmission.

The cost of achieving this higher spectral efficiency using higher order QAM is that the transmitter and receiver requires a higher signal to noise ratio (SNR) with the same...

This monograph is a translation of two seminal works on corpus-based studies of Mandarin Chinese words and parts of speech.

The original books were published as two pioneering technical reports by Chinese Knowledge and Information Processing group (CKIP) at Academia Sinica in 1993 and 1996, respectively. Since then, the standard and PoS tagset proposed in the CKIP report have become the de facto standard in Chinese corpora and computational linguistics, in particular in the context of traditional Chinese texts.

This new translation represents and develops the principles and...

This thesis reported a novel method for fabricating Lab-on-a-CD based on the platform of CD-Recording technology. Through the use of photoresist SU-8 in the indirect thermo-cured method, a protocol of cocktail approach of multiple-dye systems was developed. In this work, the compound prescription that SU-8 mixed with Cyanine was adopted in fabrication of microstructures. Various tests including spectroscopic, optical microscopic and scanning probe microscopic, and thermoanalysis have been conducted to study the SU-8 microstructures. It would be advantageous in fast prototyping and low...

Two important questions arise regarding the development of Jazz music in China. First, what common elements explain why Jazz music in these two cities, and indeed the country as a whole, is so less well developed than in other non-Western countries that managed to import and adapt it? Second, what explains the different aesthetic foci in Beijing and Shanghai, China's two greatest cities and major centers of such Chinese Jazz music? This paper examines Jazz music in these two cities, with reference to the historical roots of Jazz in China, the competing co-development of different concepts of...

The discourse constructing a queer representative with LGBT identity embodies subversive queer rebellion grounding interdependence between advertisers, stars, and audiences in commercial television. Considering her media roles for American Express, CoverGirl, and J.C. Penney, as well as a daytime talk show host, Ellen DeGeneres expresses queerness, queer moments, and space in accordance with anti-heteronormativity described by Alexander Doty. In the mainstream advertising, using LGBT subculture texts is a strategy for advertisers to target mass heterosexual consumers, while simultaneously not...

Since I was a child, I had always loved Manhattan and dreamed of moving there one day. In the autumn of 2014, I rented an apartment there for three months with the intent of looking for an apartment to purchase. So along with my two cats, Liz and Dick, I headed off to Manhattan. I spent many hours walking the streets of various areas of the city. I began taking general photos of the various neighborhoods with my iPhone. At first I took overall photos of each neighborhood then I started to look closer and deeper and began to focus on the details: old buildings, interesting doors, people, their...

Test-taking strategies and steps to succeed as an EMT

No two EMT exam experiences are exactly alike, as questions are tailored to the test-taker and range in topics from handling medical emergencies and patient assessment, to medical ethics, ambulance operations, and pediatrics. EMT Exam For Dummies takes the intimidation out of the test, offering everything you need to prepare for--and pass--the exam. Along with the book, there is also an online companion website that features two additional practice tests, and over 200 flashcards to ensure that you do your best on test...
