Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Brain is recognized as one of the complex organ of the human body. Abnormal formation of cells may affect the normal functioning of the brain. These abnormal cells may belong to category of benign cells resulting in low grade glioma or malignant cells resulting in high grade glioma. The treatment plans vary according to grade of glioma detected. This results in need of precise glioma grading. As per World Health Organization, biopsy is considered to be gold standard in glioma grading. Biopsy is an invasive procedure which may contains sampling errors. Biopsy may also contain subjectivity errors. This motivated the clinician to look for other methods which may overcome the limitations of biopsy reports. Machine learning and deep learning approaches using MRI is considered to be most promising alternative approach reported by scientist in literature. The presented work were based on the concept of AdaBoost approach which is an ensemble learning approach. The developed model was optimized w.r.t to two hyper parameters i.e. no. of estimators and learning rate keeping the base model fixed. 68 pp. Englisch.

In a democracy, the authority of the government derives solely from the consent of the governed and elections are the principal mechanism through which the consent of the people is translated into legitimate governmental authority. Apart from conferring legitimacy on governmental power, elections provide an opportunity to the citizens to make policy choices that inform public policy and governance during the term of office of the government elected. To be legitimate and democratic, elections must be competitive, periodic, inclusive and definitive. Democratic elections are an essential defining characteristic of constitutional democratic states and as such, the institutions, principles and processes that govern and inform the electoral system and process are defined in and are an integral part of the constitutions of such states. But democracy is not an end in itself, but a means to a more open and inclusive society in which the needs and aspirations of citizens are maximised and mediated in the context of a collective whole. Consequently, it is imperative to review the constitution periodically. 108 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book proposes a solution to reduce noise in a multiple access differential noise shift keying system. This method improves the performance by reducing the noise variance present in the received signal. Instead of generating noisy samples (beta), the proposed system generates only beta/M number of noisy samples and it is duplicated M times after multiplying each reference signal with a M bit Walsh code to generate the reference signal. This multiplication of Walsh code with the replicated reference signal increases the randomness between the reference signal of users, which reduces the Bit error rate or interference between signals. 128 pp. Englisch.
