Humidified gas turbines (HGT) offer the attractive possibility of increasing plant efficiency without the cost of an additional steam turbine as is the case for a combined gas-steam cycle. In addition to efficiency gains, adding steam into the combustion process reduces NOx emissions. It increases the specific heat capacity (hence, lowering possible temperature peaks) and reduces the oxygen concen
Identification of cancer subtypes is the central goal in the cancer gene expression data analysis. Modified symmetry-based clustering is an unsupervised learning technique for detecting symmetrical convex or non-convex shaped clusters. To enable fast automatic clustering of cancer tissues (samples), in this chapter, the authors propose a rough set based hybrid approach for modified symmetry-based

The papers in this volume explore the cognitive neuroscience of second language acquisition from the perspectives of critical/sensitive periods, maturational effects, individual differences, neural regions involved, and processing characteristics. The research methodologies used include functional magnetic resonance imaging (fMRI), positron emission tomography (PET), and event related potentials (
Städer i sin snävaste betydelse är ett sentida fenomen. Eftersom de vuxit fram under en process är de inte så entydigt definierade som vi i nutiden antar. Problemet blir tydligt när vi tvingas omnämna orter som ”proto-urbana” eller använda begrepp som ”centralplatser”. Dessa begrepp antyder att livsmönstret inte riktigt utvecklats till en ”riktig” stad eller att det embryonala urbana livsmönstret
