Semantic Segmentation of Intralobular and Extralobular Tissue from Liver Scaffold H&E Images

Decellularized tissue is an important source for biological tissue engineering. Evaluation of the quality of decellularized tissue is performed using scanned images of hematoxylin-eosin stained (H&E) tissue sections and is usually dependent on the observer. The first step in creating a t...

Synergy of experiment and model for reactive HiPIMS: effect of discharge parameters on WOx composition and deposition rate

Reactive high-power impulse magnetron sputtering of tungsten oxide films using metallic tungsten target (72 mm in diameter) in argon-oxygen atmosphere (total pressure of 0.75 Pa) was carried out. The effect of various discharge parameters on the deposition rate and film oxygen concentration&...

Frequency weighted H2 optimization of multi-mode input shaper

An optimization-based design of a robust multi-mode input shaper is presented with an embedded weighting of the frequency response. By prefixing the delay length in the shaper, the optimization design task is formulated as a standard quadratic programming problem. The shaper robustness ...

Model predictive control of electric drive system with L1-norm

This paper deals with the model predictive control of an electric drive system. Particularly, it focuses on the use of the L1-norm to penalize a speed deviation in a cost function of the predictive control criterion. The benefits and disadvantages of such penalization are disc...

Density Difference Grid Design in a Point-Mass Filter

The paper deals with the Bayesian state estimation of nonlinear stochastic dynamic systems. The stress is laid on the point-mass filter, solving the Bayesian recursive relations for the state estimate conditional density computation using the deterministic grid-based numerical integration method. ...

Automatic statistical evaluation of quality of unit selection speech synthesis with different prosody manipulations

Quality of speech synthesis is a crucial issue in comparison of various text-to-speech (TTS) systems. We proposed a system for automatic evaluation of speech quality by statistical analysis of temporal features (time duration, phrasing, and time structuring of an analysed sentence) together&...

Využití základních nástrojů řízení kvality v metrologii - část II.

Metrology and measurement processes use some basic quality management tools. For proper security of metrological confirmation, we must use quality management tools at different levels, as metrology, measuring processes and quality management are closely linked.

Decentralized and Distributed Active Fault Diagnosis: Multiple Model Estimation Algorithms

The paper focuses on the active fault diagnosis (AFD) of large scale systems. The multiple model framework is considered and two architectures are treated: the decentralized and the distributed one. An essential part of the AFD algorithm is the state estimation, which must be ...

Design of Rao-Blackwellized Point-Mass Smoother for Conditionally Linear and Gaussian Models

This paper deals with the state estimation of nonlinear stochastic dynamic systems. Stress is laid on the numerical solution to the functional recursive relations providing conditional probability density functions of the state. In particular, a novel Rao-Blackwellized point-mass smoother with tw...

A unified curvature-driven approach for weathering and hydraulic erosion simulation on triangular meshes

The significant properties of the maximum likelihood (ML) estimate are consistency, normality, and efficiency. While it has been proven that these properties are valid when the sample size approaches infinity, the behavior of an ML estimator when working with small sample sizes is ...
