The self-purification process of water streams is studied and the physical-chemical mechanism of it is determined. The naturally occurring self-purification process at the Boyne River site is monitored. Experiments at several creeks and…
A flotational mechanism of Etobicoke Creek's self-purification has been investigated. It is shown that the froth contains a high concentration of polluting agents. Chemical analyses of the top layer of surface water in comparison to both…
The Niagara River self-purification through the natural formation of froth at a site of the Niagara Whirlpool basin has been investigated. It is shown that the naturally formed froth on the water surface of the Niagara Whirlpool contains a…
In order to keep aquatic ecosystems safe and healthy, it is imperative that cleaning be done frequently. This research suggests the use of autonomous underwater rovers for effective underwater cleaning as a novel approach to this issue. The…
A purification scheme which utilizes the action of repeated measurements on a (part of a total) quantum system is briefly reviewed and is applied to a few simple systems to show how it enables us to extract an entangled state as a target…
Starting from the observation that reversible processes cannot increase the purity of any input state, we study deterministic physical processes, which map a set of states to a set of pure states. Such a process must map any state to the…
We survey models and algorithms for stream verification.
We describe the design, installation, and operation of a purification system that is able to provide large volumes of high purity ASTM (D1193-91) Type-I water to a high energy physics experiment. The water environment is underground in a…
Purification is a process in which decoherence is partially reversed by using several input systems which have been subject to the same noise. The purity of the outputs generally increases with the number of input systems, and decreases…
The effect of filtering operation with respect to purification and concentration of entanglement in quantum states are discussed in this paper. It is shown, through examples, that the local action of the filtering operator on a part of the…
We investigate the purification of entangled states by local actions using a variant of entanglement swapping. We show that there exists a measure of entanglement which is conserved in this type of purification procedure.
Natural language processing models have emerged that can generate usable software and automate a number of programming tasks with high fidelity. These tools have yet to have an impact on the chemistry community. Yet, our initial testing…
