Metamaterial transmission lines are considered as applied to design of advanced microwave devices with improved performance and enhanced functionality. Design examples of different microwave devices using the left-handed transmission lines are presented to demonstrate advantages in miniaturization, bandwidth broadening, and dual-band operation.
There are described the focal plane method and the back projection algorithm in multiplexed measurement systems with coded apertures for a reconstruction of spatial distributions of radiation sources. This method can be used in multiplexed measurement systems with both rectangular and hexagonal coded apertures.
Questions about construction a system of water facilities evaluation hydrobiological indicators using GIS technology. The use of hydrobiological method of valuation allows you to quickly establish the sanitary condition of the water object, to determine the degree and pattern of pollution and how it spreads. The approach of monitoring water areas on indicators characterizing the different levels of...
Electrochemical oxidation is dialysate regeneration method which can be applied in wearable artificial kidneys. In this paper results of Ti/Pt and Ti/diamond electrodes are presented. Urea oxidation rate, ion concentration and pH were measured for both types of electrodes. Urea oxidation rate for platinum and diamond was 69.54±4.3 and 30.60±4.1 mg/h respectively. Both electrodes decreased pH and increased...
Implantable medical devices can benefit greatly from wireless inductive energy supplying. At the same time, there is no universal approach to the design procedure of inductive powering unit. This paper covers two possible operation modes of the unit. Each mode has its own specific features and area of applicability. Parametric sweeps of the system output power and energy transfer efficiency are depicted...
The issue of maintaining of climatic parameters in a particular area is discussed in this paper. The mathematical model which used for calculating energy losses is shown. This module calculates the required minimum expenditure of energy to maintain climatic conditions. The paper shows the effect of using the simplex method.
