Oxidized coal as a sorbent for softening water

Sorption tests carried out oxidized nitric acid active carbon in H+- and Na+- form in relation to cations Mg2+ and Ca2+ and mixture thereof. Values obtained statistical volumetric capacity samples and mass loss them during processing nitric acid, that is oxidation state. Discovered correlation between these data and relevant sorption volume samples. Demonstrated a possible water softening oxidized coal subject to specific solution acidity.

An Analysis on the Architecture and the Size of Quantized Hardware Neural Networks Based on Memristors

We have performed different simulation experiments in relation to hardware neural networks (NN) to analyze the role of the number of synapses for different NN architectures in the network accuracy, considering different datasets. A technology that stands upon 4-kbit 1T1R ReRAM arrays, where resistive switching devices based on HfO2 dielectrics are employed, is taken as a reference. In our study, fully dense (FdNN) and convolutional neural networks (CNN) were considered, where the NN size in terms of the number of synapses and of hidden layer neurons were varied. CNNs work better when the number of synapses to be used is limited. If quantized synaptic weights are included, we observed that NN accuracy decreases significantly as the number of synapses is reduced; in this respect, a trade-off between the number of synapses and the NN accuracy has to be achieved. Consequently, the CNN architecture must be carefully designed; in particular, it was noticed that different datasets need specific architectures according to their complexity to achieve good results. It was shown that due to the number of variables that can be changed in the optimization of a NN hardware implementation, a specific solution has to be worked in each case in terms of synaptic weight levels, NN architecture, etc.

Qualitative Theory of Two-Dimensional Polynomial Dynamical Systems

A qualitative theory of two-dimensional quadratic-polynomial integrable dynamical systems (DSs) is constructed on the basis of a discriminant criterion elaborated in the paper. This criterion enables one to pick up a single parameter that makes it possible to identify all feasible solution classes as well as the DS critical and singular points and solutions. The integrability of the considered DS family is established. Nine specific solution classes are identified. In each class, clear types of symmetry are determined and visualized and it is discussed how transformations between the solution classes create new types of symmetries. Visualization is performed as series of phase portraits revealing all possible catastrophic scenarios that result from the transition between the solution classes.

This article discusses passive mechanical architectures for accuracy correction during assembly operations. A specific solution for passive force generation with thresholds is presented. Then, the kinematics of several rotational and translational mechanisms is presented. Afterwards, a case study is introduced and the design of a prototype is presented together with some tests performed on a spark plug assembly task.

A General Solution to the Rank Deficient Integer Least Squares and its Application to GNSS Positioning

<p>The contribution will present a general solution for the estimation of rank deficient integer parameters. A procedure will be presented that allows the computation of integer estimable function for any integer rank deficient least squares problem. The procedure is then applied to GNSS estimation problems. In the framework of undifferenced and uncombined GNSS models, the specific solution to some rank deficient integer least squares model will be presented, namely: the choice of pivot ambiguities in a network of receivers, GLONASS positioning, codeless positioning in the presence of ionospheric delay, satellite specific pseudorange biases estimation in the presence of ionospheric delay. It will been shown how the developed theory generalize previous results and ad hoc solutions present in the literature. Numerical results from real GNSS data will be presented too.</p>

Convergence of solutions of Hamilton–Jacobi equations depending nonlinearly on the unknown function

Motivated by the vanishing contact problem, we study in the present paper the convergence of solutions of Hamilton–Jacobi equations depending nonlinearly on the unknown function. Let H ⁢ ( x , p , u ) {H(x,p,u)} be a continuous Hamiltonian which is strictly increasing in u, and is convex and coercive in p. For each parameter λ > 0 {\lambda>0} , we denote by u λ {u^{\lambda}} the unique viscosity solution of the Hamilton–Jacobi equation H ⁢ ( x , D ⁢ u ⁢ ( x ) , λ ⁢ u ⁢ ( x ) ) = c . H\big{(}x,Du(x),\lambda u(x)\big{)}=c. Under quite general assumptions, we prove that u λ {u^{\lambda}} converges uniformly, as λ tends to zero, to a specific solution of the critical Hamilton–Jacobi equation H ⁢ ( x , D ⁢ u ⁢ ( x ) , 0 ) = c {H(x,Du(x),0)=c} . We also characterize the limit solution in terms of Peierls barrier and Mather measures.

Scientific-Practical Description Of The Status Of The Consumer As A Subject Of Relations Arising From Damage

The definition of consumer status is based on the specifics of the participation of an individual in the procurement of goods (works, services). In this case, if an individual enters into the relevant legal relationship for consumer purposes, he is recognized as a consumer.Therefore, the legislation provides that the damage caused to an individual as a result of a defect in the goods (work, service) can be compensated in the case of purchase of goods for consumer purposes. However, given the breadth and variety of scope of the legal relationship in which an individual participates, the problem of determining its purpose arises.In this case, the nature of the legal relationship and the origin of the purpose for which the goods are purchased will be a specific solution. At the same time, the application of warranty to these situations can be used effectively in solving the problem. This article analyzes the problems of determining the status of the consumer in relation to the damage caused by defects in the goods (works, services) and their solutions.

Systemic ambiguity as a motivation in the emergence of logophoricity

Chapter 4 demonstrates that a systematic ambiguity within a domain may constitute a motivation in the emergence of a function. The functional domain discussed is the domain of reference. The systematic ambiguity at play is the coding of reference in clausal complements of verbs of saying. More specifically, the question is whether the participants in the complement clause are coreferential with the participant in the matrix clause or whether they are not coreferential. Some languages deploy pronouns in the complement clause to code disjoint reference and person, number, and gender agreement on the verb to code coreference (Polish). Other languages deploy pronouns in the complement clause to code coreference and nouns to code disjoint reference (English). The specific solution described in Chapter 4 are logophoric pronouns which code not only coreference with the subject of the matrix clause but also coreference with other arguments of the matrix clause. The Chapter describes how logophoric coding emerged from the de dicto reference markers.

Translation of Trendy Expressions as Extralinguistic Culture-bound References: the Case Study of If You Are The One

Since it was introduced into Australia from China in 2013, the Chinese-to-English subtitled dating game-show If You Are The One (Fei Cheng Wu Rao / 《非诚勿扰》) has been maintaining its super high ratings on the Australian national TV station SBS for all these years. The frequently appeared trendy expressions in IYATO, as the concentrated embodiment of Chinese popular culture, are the significant and inevitable difficulties to the interlingual subtitling of the show. On the premise that the trendy expressions in the text are regarded as Extralinguistic Culture-bound References (ECRs) (Pedersen, 2005, 2011), by employing the systematic translation strategy and influencing parameter proposed by Jan Pedersen (2005, 2011) for rendering and analyzing ECRs in audiovisual works, this paper aims to investigate the specific solution adopted by the subtitler in the translation of typical trendy expression cases in the latest season of the show, so as to bring inspiration and reference to the Chinese-to-English interlingual subtitling of the language-intensive shows in the future.
