This study has tried to analyze the urban land cover change pattern of Gazipur Sadar Upazila between 2001 and 2021. This study also has made an investigation to classify the urban land cover of Gazipur Sadar Upazila based on categorical spatial zoning and analyze how urbanization affects nearby green spaces to monitor environmental criticality. Multispectral Landsat satellite imageries, population census data, air quality index, and open-ended questionnaire data were used as the operational data. Spectral indices such as NDVI, and IBI, were performed from remotely sensed satellite data. NDVI was used to extract green cover and IBI was used to extract the built-up area. Spatial zoning was done based on existing literature, expert interviews, and RS analysis. Environmental criticality was analyzed by correlating population density and air quality data with the extracted green cover. Between 2001 and...

A small deviation has been found in the characteristic curves. The characteristic curves in terms of CNT channel Diameter variation are also shown. The given parameters for the empirical model does not show proper characteristics while implementing SRAM. In this research, we found out the proper empirical model parameters that should be implemented for designing SRAM. And comparisons has been shown between the empirical model and the ideal CNTFET.
