Learning methods such as neural network and decision tree need a certain number of training samples to achieve a certain level of generalization accuracy. Analytic learning uses prior knowledge and deductive reasoning to expand the information provided by training examples, so it is not restricted by the same boundaries. This paper introduces an analytic learning method called explanation based learning (EBL). In interpretive learning, prior knowledge is used to analyze how the observed learning...

NAND flash, as the mainstream storage medium, has the advantages of high performance, high density, non-volatile and low power consumption. However, due to the special internal structure of NAND flash, it is necessary to design a special controller for data management, which is suitable for all kinds of storage systems. In this paper, a NAND flash controller based on NB-LDPC is completed. We will describe the construction of LDPC code, the implementation of encoding circuit, the realization of d...

This paper found two special points in the space of the charge distribution resulting from thermal electron emission and summed up the characteristics of the two points. Some special characteristics exist between the two points, including constant direction of potential gradient, spontaneous process of remarkable deviation from equilibrium, inconsistence of the directions of forces and fluxes etc. This paper also analyzed the entropy production rates caused by the flow going with the potential g...

Demonstrated the existence of another kind of non-equilibrium ordered structure that emerges at vapor-liquid interface spontaneously. This structure forms spontaneously due to thermal motion of the molecules moving between the vapor phase and the liquid phase. Also presented an experimental model based on this ordered structure. In the model, each spontaneous process can make a segment approach equilibrium, but also cause another segment to deviate from equilibrium. The linkage and complementari...

The present work aims to elaborate a review of the geochemical aspects used to compose the Raw Water Quality Index (WQI), highlighting lake environments and their importance for management practices. This paper is a bibliographic review based on specialized scientific and legislative literature conducted between April 2016 and March 2019. The scientific articles were selected by searching the Scielo database and the Periódicos Capes and the database search was performed using the terminologies r...

Ynones, also known as α, β-acetylenic ketones, have been widespread used in modern synthetic organic chemistry. They exist in biologically active compounds, and are used as vital building blocks in complex molecule synthesis. Consequently, a number of methodologies involving ynones have been developed to access a wide range scaffold using this simple building block. In this paper, the synthesis of a ferrocene tertiary amine cyclop

The article considers physical properties of photon as a quantum of electromagnetic wave in luminiferous medium. An experimental evaluation method for its energy and mass based on radiation pressure effect was presented. The of “photon amplitude” concept was introduced, through which energy is represented similarly to quantum (phonon) energy of elastic mechanical wave. A model of photon as a wave packet in the medium was considere

Sclerosis (MS) is the most common disability in young adults that requires
early symptomatic treatment to prevent long-term disability. Among young
adults, MS is the most common central nerv-ous system (CNS) chronic
inflammatory illness that is characterized by demyelination in the CNS.
However, current disease-modifying treatments are not sufficiently effective
for preventing the variety of symptoms during the co

The paper draws attention to the importance of the notion “luminiferous ether” in physics. There is a proposed method to register its flows generated by natural cosmic movements or created artificially. The work presents the results of ether wind searching with a prototype of the proposed installation located at the altitude of <30 m above sea level. Ether flows with speeds > 20 km/s are not found, which is consistent with the results of previous experiments.
