Research on Pricing Mechanism and Security of Digital Currency

With the rapid development of block chain technology and its application, digital currency, which does not rely on national credit endorsements, is emerging. The financial technological innovation is becoming another strong driving forces for promoting social and economic developments. Unlike the price formation mechanism of traditional fiat currency, the price formation mechanism for digital currency is still unclear. Because financial regulators cannot accurately predict the price trend of digital currency, there is a corresponding lack of means to intervene in the price of digital currency in time of crisis. The lack of such technology also provides a way for security attackers with ulterior motives to attack the monetary system by manipulating the prices of digital currency. This paper will take Bitcoin as an example to study the price formation mechanism of digital currency, therefore clarifying the factors affecting the price of digital currency, and provide the means of price supervision, prediction and intervention for financial regulators to ensure the development of digital currency.
Color-based Object Categorization Model Using Fuzzy HSV Inference System

Color is one of the most identifiable properties of objects and wide range of colors need to be detected. Images captured in RGB color space are hard to extract more than three colors from them due to their cubic shape of merging luminance, saturation, and color spectrum. This paper presents a color-based Object Categorization model that utilizes the HSV color space. The process starts by converting the RGB space into three main components, Hue (wavelength of colors), Saturation (purity of colors), and Value (grayness level or lightness), Unfortunately, Hue causes some sort of fogginess when color classification is applied, due to the gradient between each color. For that, the hue fuzzy sets are used which categorize colors in images. They are used to identify nine deferent object's color and categorize them into the nine common pure colors. The categorization process is then carried out by a PUMA 560 robot in nine different trajectories based on the colors extracted by the fuzzy sets. In order to illuminate bright and dark objects and putting them into the tenth trajectory of the unwanted objects, we modified the saturation and value as fuzzy sets. The system is simulated, tested and proved its effectiveness in detecting colored objects due to their gradient and variations for environments with normal or highly structured light settings, using medium or high-resolution camera.
Psychological and Pedagogical Problems of Beginning Lecturers and Postgraduate Students at Engineering University

The paper discusses the psychological and pedagogical problems faced by beginning teachers and postgraduate students in their pedagogical work at an engineering and technical university. The study shows that the most significant problems concern the variety of the roles of the respondents and their lack of psychological and pedagogical training. Postgraduate students and beginning teachers must be engineers, researchers and educators at the same time. The paper demonstrates the interrelation between the role positions of a teacher at a technical university. However, to implement these roles, a specialist has to have a diverse set of competences. Every specialist is more apt to one or another of these roles. Moreover, the role of an educator is not of top priority for postgraduate students. In the authors’ opinion, this calls for correcting the way training is organized for future teachers of an engineering and technical university with due consideration of personal priorities in their professional work and the needs of universities for replenishing their pedagogical cadres with specialists educated in accordance with the necessities of the time.
Subtraction-Positive Similarity Learning

Many methods evaluate the similarity between two vectors x and y by norm or metric learning. They need to get a subtraction vector x - y and then evaluate its length. However, only considering the length of subtraction vector and ignoring its position may lost a lot of information. In this paper, we propose to utilize the position information of subtraction vector to evaluate the similarity. As the subtraction vector between x and y can be expressed either by x-y or by y-x, its distribution is centrosymmetric and redundancy. Thus, only half of the subtraction vectors are chosen and named as subtraction positive vectors. The subtraction positive vectors from different classes or from the same class are then modeled by Gaussian mixture models or deep neural network. Experiments were carried out on speaker verification databases including NIST SRE08, SRE10 and NIST i-vector challenge 2014. Results demonstrate the effectiveness of the proposed method.
