The scalar-valued score functions of continuous probability distribution
Fabián, Zdeněk
2019 - English
In this report we give theoretical basis of probability theory of continuous random variables based on scalar valued score functions. We maintain consistently the following point of view: It is not the observed value, which is to be used in probabilistic and statistical considerations, but its 'treated form', the value of the scalar-valued score function of distribution of the assumed model. Actually, the opinion that an observed value of random variable should be 'treated' with respect to underlying model is one of main ideas of the inference based on likelihood in classical statistics. However, a vector nature of Fisher score functions of classical statistics does not enable a consistent use of this point of view. Instead, various inference functions are suggested and used in solutions of various statistical problems. Inference function of this report is the scalar-valued score function of distribution.

Absolute Value Mapping
Rohn, Jiří
2019 - English
We prove a necessary and sufficient condition for an absolute value mapping to be bijective. This result simultaneously gives a characterization of unique solvability of an absolute value equation for each right-hand side. Keywords: absolute value mapping; bijectivity; interval matrix; regularity; absolute value equation; unique solvability Available in a digital repository NRGL

Does minimum wage affect workplace safety?
Hradil, Vít
2018 - English
Empirical evidence on the employment effects of minimum wage legislation suggests the possibility that firms react to increases in low-skilled labor costs driven by minimum wages\nby reducing investments in non-wage job aspects, which can mitigate the need for layoffs. Such adjustments may involve the worsening of workplace safety. To evaluate the hypothesis that increases in minimum wages result in a higher incidence of occupational injuries and illnesses, I use employer-level data from the United States and variation in state minimum wages during 1996-2013. The results suggest that states which increase their minimum wage experience an increase in the incidence of occupational injuries and illnesses. The effect appears stronger in industries that employ large numbers of low-wage workers, and those where the workforce is intensively exposed to health risks. Keywords: minimum wage; job safety; occupational injuries and illnesses Fulltext is available at external website.

The low-skilled in the Czech Republic
Bičáková, Alena; Kalíšková, Klára
2018 - English
This study provides evidence on the characteristics, labor market conditions, and labor market\noutcomes of the low-skilled in the Czech Republic. It considers the most relevant policies to\nensure the long-term inclusion of the low-skilled in the labor market. We use the standard\ndefinition of the low-skilled as those individuals with primary or lower-secondary education. Keywords: labor market conditions; labor market outcomes; Czech Republic Fulltext is available at external website.

Balancing Exploitation and Exploration via Fully Probabilistic Design of Decision Policies
Kárný, Miroslav; Hůla, František
2018 - English
Adaptive decision making learns an environment model serving a design of a decision policy. The policy-generated actions influence both the acquired reward and the future knowledge. The optimal policy properly balances exploitation with exploration. The inherent dimensionality\ncurse of decision making under incomplete knowledge prevents the realisation of the optimal design. Keywords: Exploitation; Exploration; Bayesian estimation; Adaptive systems; Fully probabilistic design; Kullback-Leibler divergence; Decision policy; Markov decision process Fulltext is available at external website.

Structural mapping of exploration boreholes walls within first phase - Safety boreholes for Boxcut
Waclawik, Petr; Souček, Kamil; Vavro, Martin; Kukutsch, Radovan; Ram, S.
2018 - English
Structural-geological analysis, i.e. core fracturing assessment within the boxcut safety\nborehole was carried out on the basis of optical televiewer record evaluation. In general,\noptical televiewer (OPTV) probe provides a continuous, unwrapped, high-resolution digital\n360° image of the borehole-walls oriented towards the cardinal points. This technique\nprovides information about the strike, dip direction, dip angle and depth of foliation, bedding\nplanes and fractures, as well as the frequency, aperture and infillings of fractures. Information\nabout spatial characteristics of structural elements is one of its indisputable advantages and\nallows for subsequent statistical evaluations.\nThe structural mapping of boreholes of Boxcut safety boreholes were carried out within the\ncontract of IG CAS (Contract No. D/18/156/00) GEOMET, s.r.o. (as a customer, contract No.\n01/2018). The aim of the contractual research was the realisation and interpretation of the\nfractures by digital logging of boreholes walls.

Validation of comprehensive energy management system based on cloud-sourced information
Nedoma, P.; Herda, Z.; Franc, Z.; Plíhal, Jiří
2018 - English
The main research activity was devoted to develop an application that would enable testing interface between OIKOS board (based on the AURIXTM) and the dissemination module represented by Skoda vehicle demonstrator through serial port RS232. The testing was based on sending the GPS coordinates to the OIKOS unit and receiving recommended speed profile for the given track. While dissemination unit has received GPS coordinates, AURIX chip has sent back messages with prediction of possible speed profile. Further tasks included verification other forms of transmission, such as Wi-Fi, Bluetooth, Ethernet.\n\n Keywords: OIKOS board; dissemination module; GPS Fulltext is available at external website.
