The optimization of express estimation of complex dynamic objects nowadays often are used principles of the information theory. It is true as far as the behavior of the object under study is random. Recently, it is observed that the creation of a new approach is frequently based on the implementation of the entropy measure and permutation encoding. It can be used as information for the survey procedure of the complex dynamic cyber-physical system as well. It is done the survey algorithm description and it's illustrated example.

Online incipient chatter detection is a crucial task to improve surface quality, reduce dimensional errors, and protect the cutting tool and machine tool in the highspeed milling process. Since variable background noise in measured signal impacts the accuracy of the incipient chatter detection, it is necessary to develop an appropriate and efficient threshold to detect incipient chatter reliably. This paper proposes an online incipient chatter detection method for high-speed milling process based on once-per-revolution sampling and dynamic threshold variant. First, the once-per-revolution sampling technique is used to reduce the data size and acquire independent data of machining parameters. Next, an incipient chatter indicator MaxEnt, i.e., maximum entropy, is extracted from the once-per-revolution sampled data by using the MaxEnt principle. Finally, a dynamic threshold variant and sequential probability ratio test (SPRT) are used for incipient chatter detection. To validate the effectiveness of the proposed method, a simulated chatter signal, including seven components, is employed. The validated results show that the proposed method could detect the incipient chatter effectively in the variable noise environment.

The exploration of planetary surfaces lies on images and topographic data, typically derived by laser altimetry from planetary missions. This paper deals with an examination of the topography data from the Mars orbiter laser altimeter (MOLA). MOLA data to be processed is massive and 3D dimensional but the obtained resolution of the martian surface is limited to the altimeter data density, especially along the cross-track directions. Therefor a tensor representation can be used to model these types of noise. In this paper an approach to assessing along-track and cross-track noise on altimeter data using a tensor decomposition is proposed. Experimental results show that the quality of the reconstituted signal in the different planes are excellent.

The approach to the use of Internet-devices and Bigdata information technologies while implementing the "Smart Cities" projects by means of information-technological platform of telemetric calculations of water, heat, gas and electricity consumption is proposed by the authors. In the basic version of the offered platform several generations of digital devices for telemetric data transmission capable to be connected to the Internet network by means of network interfaces (LAN) and mobile networks are used. The developed information-technological platform provides combination of Internet devices technology and Bigdata contributing to quick analysis and processing of a large number of obtained and delivered data sets.

Recently, domain-specific language has become more popular in the IT market. Therefore, there are several variants of the domain-oriented programming languages used in the modern world. A variant of domain-specific language that accepts wind farm modeling language at the input and GPSS code at the output to model the queuing system has been proposed in this paper. The ANTLR grammar rules for the implementation of wind farm modeling language have been formed.

Space-filling curves are well known for preserving pixel locality when they are used as paths to traverse 2D image data. Some prediction-based compression algorithms make use of these curves to ensure high pixel values correlation during 2D image data traversal. This work explores the distribution of pixel correlation induced by all possible space-filling curves on 2D image data and demonstrates that commonly used curves, such as the Hilbert or the Peano curves, do not provide the best possible pixel correlation for natural photographic images. Using experimental data collected on a large set of such images, we demonstrate that row-prime ordering is the best choice for preserving maximum pixel values correlation while reducing the dimensionality of 2D natural photographic image data.
