Opis:
The social sciences in the recent past have become quite specialized in terms of the problems and responses covered in their purview. The origin of Criminology as specialized branch of learning was a part of similar process. Early Criminology better known as classical criminology emerged as part of protest against the prejudiced and discriminating legal practices that were prevalent in the contemporary society of the early eighteenth century. The leaders of criminal justice reforms were Baccaria and Bentham who demanded the reforms in the law and procedure. Afterwards Criminology has grown to be an advanced field of learning and practice. Emphasis in Criminology, in the interpretation of crime and criminality, has been changing over a period of time. The schools of thoughts in Criminology have been moving from classical to physiological, environmental to psychological and sociological to interactionist approaches and so on. Criminology has been defined as the study of crime, the causes of crime (etiology), the meaning of crime in terms of law, and community reaction to crime. Not too long ago, criminology separated from its mother discipline, sociology, and although there are some historical continuities, it has since developed habits and methods of thinking about crime and criminal behavior that are uniquely its own. Criminology is hence perceived as a most inclusive concept. Criminology involves the inputs from all basic disciplines in social and behavioural sciences in explaining the problem of and response to crime (Jatar, 1979).

Opis:
Silicon carbide (SiC) power devices offer significant benefits of improved efficiency, dynamic performance and reliability of electronic and electric systems. The challenges and prospects of SiC power device development are reviewed considering different device types. A close correlation between an exponential increase of current handling capability during recent five years and improvement in substrate quality is demonstrated. The voltage range of silicon and SiC unipolar and bipolar power devices with respect to the on-state voltage is determined based on device simulation. 4H-SiC unipolar devices are potentially superior to all silicon devices up to 10 kV.4H-SiC unipolar devices are superior to all SiC bipolar devices up to 8÷9 kV. The low end of SiC unipolar devices is determined to be around 200 V provided substrate resistance is reduced by thinning the substrate down to 100 žm. The influence of reduced channel mobility on the specific on-state resistance of 4H-Sic DMOSFETs and UMOSFETs is shown. It has been demonstrated that 6H-SiC DMOSFETs could be a better choice compared to 4H-SiC MOSFETs in the voltage range below 600 V utilising better channel mobility obtainable so far on 6H-SiC polytype. An impact of super junction (SJ) concept on silicon and SiC MOSFET specific on-resistance limits is demonstrated.
