In standard power cycling tests, forward conduction generates heat in the die and therefore the ther-momechanical stress in the package. In application, however, a significant part of the power losses are switching losses, so that the load current is lower than in standard power cycling test, for an equal temperature swing. A new concept for power cycling tests is presented, which allows the generation...
The problems of implementation and benefits of archival information retrieval system for processing information requests of citizens in the structural units of higher educational establishments are considered. It is proposed to automate the delivery of services in pursuance of biographical and factual queries by archival departments of universities through issuing archival information, excerpts and...
Projects are one of the most important organizational patterns in industry and society. Projects drive change and change takes place in a projectized world. Therefore, project management is a competence field which is required in many areas and on various competence levels. Master education in project management is a special type of delivery for project management competence. It combines a scientific...
The problem of input saturation in linear-quadratic-gaussian (LQG) control of a single-phase converter with LCL filter is addressed by design of an anti-windup compensator. Since the full state is not directly observed, a Kalman filter observer has been designed. Performance of the proposed control is illustrated on simulation examples under ideal sinusoidal source and source with additional harmonics.
The paper gives a brief presentation of organizational and methodical peculiarities of university degree programs public professional accreditation as affective mechanism for quality assurance in engineering education in Russia, USA, Canada, and EU countries.
These days, passengers can use their portable electronic devices (PEDs) in more and more aircraft. Even in those aircraft, where less than 5 years ago this was strictly forbidden. It is safe to say, that with respect to EMC neither the aircraft nor the portable devices have changed much in the last 5 years. So why can authorities and industry now accept, what was inacceptable for such a long time?...
The City4age project combines Internet of Things, data from smart cities and powerful schemes for sending messages, to develop sustainable prevention of MCI/Frailty in aging population. To do so, it combines detection (for early spotting of symptoms) and intervention (for suggesting positive changes of behavior).
Parity RAIDs are used to protect storage systems against disk failures. The idea is to add redundancy to the system by storing the parity of subsets of disks on extra parity disks. A simple two-dimensional scheme is the one in which the data disks are arranged in a rectangular grid, and every row and column is extended by one disk which stores the parity of it.In this paper we describe several two-dimensional...
Sampling from multi-dimensional and complex distributions is still a challenging issue for the signal processing community. In this research area, Hamiltonian Monte Carlo (HMC) schemes have been proposed several years ago, using the target distribution geometry to perform efficient sampling. More recently, a non-smooth HMC (ns-HMC) scheme has been proposed to generalize HMC for distributions having...
Nowadays, more and more Cloud providers are appearing on the market. In this context, a typical issue is represented by the management of distributed services deployed on different federated Cloud providers. Assuming that a distributed service consists of several microservices, in this paper, we specifically focus on the setup of virtual environments and on deployment tasks required in each Federated...
Recent developments in the standardisation of High Efficiency Video Coding (HEVC) have shown that the block-wise activation/deactivation of a colour transform can significantly improve the compression performance. This coding tool is based on a fixed colour space which is either YCgCo in lossy compression mode or YCgCo-R in the lossless mode. The proposed method shows that the performance can be increased...
Graph-based semi-supervised learning for classification endorses a nice interpretation in terms of diffusive random walks, where the regularisation factor in the original optimisation formulation plays the role of a restarting probability. Recently, a new type of biased random walks for characterising certain dynamics on networks have been defined and rely on the γ-th power of the standard Laplacian...
Automatic Music Transcription (AMT) is concerned with the problem of producing the pitch content of a piece of music given a recorded signal. Many methods rely on sparse or low rank models, where the observed magnitude spectra are represented as a linear combination of dictionary atoms corresponding to individual pitches. Some of the most successful approaches use Non-negative Matrix Decomposition...
Intra prediction is a significant coding tool that allows a high level of video compression to be achieved in the current state-of-the-art video coding standard, High Efficiency Video Coding (HEVC), and the joint exploration model (JEM) developed by the Joint Video Exploration Team (JVET) of ITU-T VCEG and ISO/IEC MPEG for the next generation video coding standard. In intra prediction, the top and...
With the recent introduction of High Dynamic Range (HDR) and Wide Color Gamut (WCG) technologies, viewers' quality of experience is highly enriched. To distribute HDR videos over a transmission pipeline, color pixels need to be quantized into integer code-words. Linear quantization is not optimal since the Human Visual System (HVS) do not perceive light in a linear fashion. Thus, perceptual transfer...
JPEG 2000 is one of the most efficient and well performing standards for continuous-tone natural images compression. However, a compression performance loss may occur when encoding images with sparse or locally sparse histograms. Images of the later type include only a subset of the available intensity values implied by the nominal alphabet. This article proposes a new adaptive block-based histogram...
Social networks have been applied in football, or football match analysis to analyze the passing distributions between teams. However, analysis has been mostly done on a manually collected data by considering the widely adopted network metrics such as betweenness and closeness centrality. In this paper, we use professional tracking event data provided by OPTA Sports and analyze the final game of the...
This study used MODIS 3 KM Aerosol Optical Depth (AOD) products, ground-level PM2.5 measurements in Beijing and the Public Health knowledge to estimate the number of death attributed to the long-term exposure to a harmful level of PM2.5 concentrations. The study results demonstrated that 2015 population-weighted averaged PM2.5 in Beijing was 70.46 μg/m3, 369.73% exceeding the China's yearly standard...
The paper describes the RE-SEARCH ALPS project, which aims to gather, consolidate, harmonize and make available to different targets (public and private bodies working at local, regional and national level) data about laboratories, research and innovation centers which are active in particular in the regions of seven countries which constitute the Alpine Area (France, Italy, Switzerland, Austria,...
Digital collections are increasingly used for a variety of purposes. In Europe only, we can conservatively estimate that tens of thousands of users consult digital libraries daily. The usages are often motivated by qualitative and quantitative research. However, caution must be advised as most digitized documents are indexed through their OCRed version, which is far from perfect, especially for ancient...
