in this paper, a new circuit is proposed for step-up z-source inverter based on qzsi (quasi-z-source inverter). the proposed topology inherits all advantages of the conventional topology. the proposed topology in comparison with conventional topology reduces the st (shoot-through) duty cycle by over 25% at the same voltage boost factor. theoretical analysis of the proposed qzsi in the st and no...

let  be a graded ring and  be a graded -module. we define a topology on graded prime spectrum  of the graded -module  which is analogous to that for , and investigate several properties of the topology.

in this paper, a pointwise pseudo-metric function on the l-realline is constructed. it is proved that the topology induced by this pointwisepseudo-metric is the usual topology.

Abstract Extreme-high-speed communication exceeding 100 Gbps is one requirement for 6G. To satisfy extreme-high-speed-communication, solution to utilize terahertz bands above GHz. determine the new radio-interface technologies and service frequency 6G, propagation characteristics GHz need be understood. In this paper, we introduce our radio-network topology 6G then show dependency of key phenom...

citrus fruits contain numerous nutrients and secondary metabolites including sugars, vitamin c, flavonoids and phenols which have high antioxidant activity and nutritional value. factors such as cultivar, type of stock and fruit position affect the amount of these compounds. hence in this study the amount of sucrose, glucose, total sugar, vitamin c, flavonoids and phenols in pulp, mesocarp and ...

simulation of rough rice drying is one of the proper methods for predicting moisture distribution in the product, and throughout the process of drying. the drying process must be well understood and controlled so that design guidelines which reduce or minimize drying damage to rough rice can be established and improved. therefore, an accurate understanding and description of the drying mechanis...

We present a randomised potential-field based motion planning approach for rough-terrain mobile robot navigation. The motion planning component is closely integrated with a real-time capable rigid-body kinematics and dynamics simulation module. The terrain is approximated as a polygonal surface generated from height data. The robot interacts with the terrain, modelled as a series of physically ...
