Accumulators of high thermal capacity are organized in a natural soil mass ordered by set ("bush") vertical/horizontal heat exchangers, which placed either boreholes or inside cylindrical cavities concrete pipes. As result accumulation, main region accumulated is created, limited the outer contour "bush", certain volume and with temperature, as well buffer sub-region volume, touches one interac...

Compact e-cash schemes allow users to withdraw a wallet containing K coins and to spend each coin unlinkably. We present the first compact e-cash scheme with arbitrary wallet size k ≤ K while the spending protocol is of constant time and space complexity. Known compact e-cash schemes are constructed from either verifiable random functions or bounded accumulators. We use both building blocks to ...

A novel adaptive step size control algorithm is proposed, in which the step size is approximated to the theoretically optimum value via leaky accumulators, realizing quasioprimal control. The algorithm is applicable to most of the known tap weight adaptation algorithms. Analysis yields a set of difference equations for theoretically calculating expected filter convergence, and derives residual ...

− Some measuring systems are very sensitive on disturbances incoming from power supplies. If no accumulators are used for their power supply, which ensure a minimum signal noise and transmission jamming signal from power network, special power supplies have to be constructed for them. An example of a possible influence of a disturbance, which spreads along to the power supply on high pure sine-...

Atmospheric scientists need to observe fluctuations in the ionosphere, both to probe the underlying atmospheric physics, and to remove the effects of these fluctuations from other measurements. We have built an FPGA-based, pipelined array processor that allows us to make these observations in real-time, using passive radar techniques. Our array processor time-multiplexes 16 multiply–accumulator...

Based on the analysis of the structure and the power transmission system of aircraft towing tractor, a new project applying hydraulic drive hybrid power is put forward considering the requirements of towing aircraft and working process without towbar. As the testing and controlling signals of the system are multi channel and distributed, the testing program is designed via LXI bus. The experime...

This research aims to extend the existing knowledge on air quality improvement by arboreal–shrub heritage. The PM accumulation (PM10–100, PM2.5–10, and PM0.2–2.5 (µg·cm−2)) was measured with consolidated gravimetric techniques during spring, summer, fall for 2160 leaf samples belonging basal, median, apical part of crown 17 species located in streets parks 2 European cities (Rimini Krakow).
