introduction morphological segmentation of land surface is commonly used for land surface allocation in management and environmental sciences. the first step in assigning a piece of land to a specific application is to divide it into homogeneous morphological segments. traditional field-based geomorphological mapping can be time consuming, costly, and challenging when large areas, particularly ...

Although microplastics (MPs) are ubiquitous environmental contaminants, little is known about their occurrence and behavior in the terrestrial setting. In this study, MPs have been isolated from soils collected various geomorphological features (yardangs, sand dunes, moving sands, seasonal lakes) of Kavir Lut Deserts on Iranian plateau. The number identified 300 g samples ranged zero (not detec...

We investigated the hardware implementation of an area-efficient superconducting lookup table (LUT) based on a single flux quantum (SFQ) logic by using newly proposed small memory cell. The cell is composed nondestructive read-out (NDRO) flip-flop with input circuits that convert dc current to SFQ pulse signal. datum can be written selected in 2-D array applying both <italic xmlns:mml="http://w...

A novel approach to testing lookup table (LUT) based field programmable gate arrays (FPGAs) is proposed in this paper. A general structure for the basic configurable logic array blocks (CLBs) is assumed. We group k CLBs in the column into a cell, where k denotes the number of inputs of an LUT. The whole chip is configured as a group of one-dimensional iterative logic arrays of cells. We assume ...

The objective of our article is to demonstrate that some physical defects in a LUT can change its propagation delay. We propose a simplified 'timing' model of the LUT which determines its propagation delay. Such a model is exploited to analyse the effects of a defect on the LUT behaviour, from which we demonstrate that they can cause a timing fault on it. Anywhere in a LUT, a timing defect can ...
