A recent paper by Knorr et al. (2005a) suggested that the decomposition of resistant soil organic matter is more temperature sensitive than labile organic matter. In Knorr et al.’s (2005a) model, the reference decay rate was presumed to be same for all pools of soil carbon. We refit Knorr et al.’s (2005a) model but allow both the activation energy and the reference decay rate to vary among soil...

and responses from Lomas (Lomas 2005a) and Lavis (Lavis 2005) under the umbrella title Perspectives on Evidence, Synthesis and Decision-Making. Together with Lomas' s essay in our inaugural issue (Lomas 2005b), they provide sometimes complementary , sometimes competing, but invariably thoughtful perspectives on how (and to what extent) research and other evidence can be synthesized, presented a...

In this study, the channel estimation technique for OFDM systems based on Artificial Neural Networks is investigated. This is realized by cosimulation environment to utilize the advantages of different modeling programs. In this cosimulation, Advanced Desing System (ADS 2005A) and MATLAB programs have been used. Both transmitter and receiver of OFDM system and the transmission medium are design...

ii Acknowledgements I sincerely thank my parents and my sister. Without their encouragement, I would not have embarked my journey to this country. I sincerely thank Dr T. Warren Liao for providing me with invaluable guidance, constant encouragement and support throughout the course of my work. He has been very patient in explaining to me about writing a thesis. I have learned many valuable less...

My research explores, develops and evaluates novel technologies and techniques that aim to overcome challenges in interactions between humans and computers, especially in emerging use modalities such as mobile computing, touch interfaces and gestural interaction. Beyond my immediate background in computer science, I draw on a diverse set of skills, including interaction design, physical fabrica...

Preface Invictus Out of the night that covers me, Black as the Pit from pole to pole, I thank whatever gods may be For my unconquerable soul. In the fell clutch of circumstance I have not winced nor cried aloud. Under the bludgeonings of chance My head is bloody, but unbowed. Beyond this place of wrath and tears Looms but the Horror of the shade, And yet the menace of the years Finds, and shall...

Forensic Computing is a new and quickly developing field. It is in the process of becoming an academic discipline or sub-discipline with all the features from full undergraduate and postgraduate course provision to conferences and journals. An important question in this process of turning into an established discipline is whether it will coincide with the recognition of the graduates as profess...

Endometrial cancer, cancer of the lining of the uterus, is the most common gynecologic malignancy in the United States, with an estimated 40,880 new cases diagnosed in 2005 (American Cancer Society [ACS], 2005a). Fortunately, mortality rates for endometrial cancer are relatively low, with 96% of women living five years or longer after being diagnosed with localized disease. Most women (72%) are...

In the 1930s, when the British ruled the country, Jawaharlal Nehru described India's situation as follows: "A servile state, with its splendid strength caged up, hardly daring to breathe freely, governed by strangers from afar; her people poor beyond compare; shortlived and incapable of resisting disease and epidemic; illiteracy rampant; vast areas devoid of all sanitary or medical provision; u...
