  2. 1. Causal links of past climate change in Coupled Model Intercomparison Project Phase 5 climate models

    Author : Thanh Le; MERGE: ModElling the Regional and Global Earth system; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; solar forcing; volcanic forcing; greenhouse gases radiative forcing; Granger causality; near-surface air temperature; ENSO; IOD; CMIP5; North Atlantic;

    Abstract : The climate system is influenced by various external forcings (e.g. volcanic forcing, solar forcing and change of greenhouse gas concentrations) and its own internal climate variability. READ MORE

  4. 2. Drill Failure Detection based on Sound using Artificial Intelligence

    Author : Thanh Tran; Jan Thim; Sebastian Bader; Kalle Åström; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Convolutional neural network; machine failure detection; Mel-spectrogram; long short-term memory; sound signal processing;

    Abstract : In industry, it is crucial to be able to detect damage or abnormal behavior in machines. A machine's downtime can be minimized by detecting and repairing faulty components of the machine as early as possible. It is, however, economically inefficient and labor-intensive to detect machine fault sounds manual. READ MORE

  5. 3. Enhancing Machine Failure Detection with Artificial Intelligence and sound Analysis

    Author : Thanh Tran; Jan Lundgren; Sebastian Bader; Domenico Capriglione; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Failure Detection; Machine Learning; Deep Learning; Sound Signal Processing; Audio Augmentation;

    Abstract : The detection of damage or abnormal behavior in machines is critical in industry, as it allows faulty components to be detected and repaired as early as possible, reducing downtime and minimizing operating and personnel costs. However, manual detection of machine fault sounds is economically inefficient and labor-intensive. READ MORE

  6. 4. Main-Memory Query Processing Utilizing External Indexes

    Author : Thanh Truong; Tore Risch; Martin Kersten; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Database indexing; query processing; index structures; main-memory; index validation; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Abstract : Many applications require storage and indexing of new kinds of data in main-memory, e.g. color histograms, textures, shape features, gene sequences, sensor readings, or financial time series. READ MORE

  7. 5. Towards alkali-stable polymers and hydroxide exchange membranes functionalized with alicyclic quaternary ammonium cations

    Author : Thanh Huong Pham; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydroxide exchange membrane; fuel cell; alicyclic quaternary ammonium; alkali-stable; high hydroxide conductivity; structure-property relationship;

    Abstract : In the current work, cationic polymers functionalized with N-alicyclic quaternary ammonium (QA) cations were synthesized and characterized as potential hydroxide exchange membranes (HEMs) for application in fuel cells. Three different polymers, namely poly(arylene ether sulfone), spiro-ionene and poly(arylene alkylene), were explored as polymer backbones for the HEMs. READ MORE
