Comparison of Three Imputation Methods for Groundwater Level Timeseries
This study compares three imputation methods applied to the field observations of hydraulic head in subsurface hydrology. Hydrogeological studies that analyze the timeseries of groundwater elevations often face issues with missing data that may mislead bot ...
MDPI2023Optimizing Sales Forecasting, Inventory, Pricing and Sourcing Decisions
In this thesis we address various factors that contribute both theoretically and practically to mitigating supply demand mismatches. The thesis is composed of three chapters, where each chapter is an independent scientific paper. In the first paper, we dev ...
EPFL2023SPHARMA approximations for stationary functional time series on the sphere
In this paper, we focus on isotropic and stationary sphere-cross-time random fields. We first introduce the class of spherical functional autoregressive-moving average processes (SPHARMA), which extend in a natural way the spherical functional autoregressi ...
2021Bioclimatic conditions of the Lower Silesia region (South-West Poland) from 1966 to 2017
This work analyses the temporal and spatial characteristics of bioclimatic conditions in the Lower Silesia region. The daily time values (12UTC) of meteorological variables in the period 1966–2017 from seven synoptic stations of the Institute of Meteorolog ...
Springer2020Dynamic Federated Learning
Ali H. Sayed, Stefan Vlaski, Elsa Rizk
Federated learning has emerged as an umbrella term for centralized coordination strategies in multi-agent environments. While many federated learning architectures process data in an online manner, and are hence adaptive by nature, most performance analyse ...
IEEE2020Global Auto-regressive Depth Recovery via Iterative Non-local Filtering
Pascal Frossard, Jingyu Yang, Xinchen Ye
Existing depth sensing techniques have many shortcomings in terms of resolution, completeness, and accuracy. The performance of 3-D broadcasting systems is therefore limited by the challenges of capturing high-resolution depth data. In this paper, we prese ...
IEEE2019Mutually Coupled Time-to-Digital Converters (TDCs) for Direct Time-of-Flight (dTOF) Image Sensors
Edoardo Charbon, Preethi Padmanabhan, Augusto Ronchini Ximenes
Direct time-of-flight (dTOF) image sensors require accurate and robust timing references for precise depth calculation. On-chip timing references are well-known and understood, but for imaging systems where several thousands of pixels require seamless refe ...
2018Noise Analysis For Environmental Loading Effect On Gps Position Time Series
Jean-Philippe Lucien Montillet, Feng Zhou
This paper focusses on the impact of environment mass loading on GPS time-series of position changes and noise characteristic. We make use of position time series of 206 GPS station ranging from 2001 to 2013 globally distributed. Firstly, we investigate th ...
Institute of Rock Structure and Mechanics, AS CR2017Simultaneous estimation of phase derivative and phase using parallel Kalman filter implementation
Pramod Rastogi, Rishikesh Dilip Kulkarni
This paper proposes a technique for the simultaneous estimation of interference phase derivative and phase from a complex interferogram recorded in an optical interferometric setup. The complex interferogram is represented as a spatially varying autoregres ...
