Experimental study on the transient behaviors of mechanically pumped two-phase loop with a novel accumulator for thermal control of space camera payload

Applied Thermal Engineering, 2020
Mechanically pumped two-phase loop (MPTL) shows a promising prospect in thermal control of space camera payload. However, transient behaviors of MPTL caused by start-up and heat sources load-on/off are rarely reported.

Operational control on environmental safety of potentially toxic elements during thermal conversion of metal-accumulator invasive ragweed to biochar

Journal of Cleaner Production, 2018
Ragweed (Ambrosia artemisiifolia L.), a metal-accumulator invasive species, was pyrolyzed under a range of pyrolytic conditions to investigate their influence on immobilization and environmental safety of potentially toxic elements (PTEs) in the produced

A2Q+: Improving Accumulator-Aware Weight Quantization

International Conference on Machine Learning
Quantization techniques commonly reduce the inference costs of neural networks by restricting the precision of weights and activations. Recent studies show that also reducing the precision of the accumulator can further improve hardware efficiency at the

Accumulate repeat accumulate coded modulation

IEEE MILCOM 2004. Military Communications Conference, 2004., 2005
In this paper we propose an innovative coded modulation scheme called "accumulate repeat accumulate coded modulation" (ARA coded modulation). This class of codes can be viewed as serial turbo-like codes, or as a subclass of low density parity check (LDPC) codes that are combined with high level modulation.

Accumulation

2013
From food punnets to credit cards, plastic facilitates every part of our daily lives. It has become central to processes of contemporary socio-material living. Universalised and abstracted, it is often treated as the passive object of political deliberations, or a problematic material demanding human management.

The use of a PCM heat accumulator to improve the efficiency of the district heating substation

Energy, 2019
One of the ways to decrease atmospheric pollution resulting from low-emissions is the widespread use of district heating systems. An important problem for the efficiency of district heating systems is a significant source-end-users difference of heat ...

HYDRAULIC ACCUMULATOR, ESPECIALLY BLADDER ACCUMULATOR

2002
The invention relates to a hydraulic accumulator, especially a bladder accumulator, comprising an accumulator housing (10), a separation element disposed therein that separates within the accumulator housing a gas chamber (16) adjoining a inlet (14) on the gas side from a fluid chamber (18) adjoining an inlet (20) on the fluid side.

Starting Accumulation vs Primitive Accumulation

2014
Marx handed over the tradition of understanding primitive accumulation as a single act of creation of capitalism; not as the first technological leap, which was industrialisation, out of the sequence of further leaps. Consequently, scholars, studying joint features of initial industrialisation in different countries, do not always notice that those ...
