  1. 1. An Evaluation Study of Leak Testing Technologies for Watertight Plate Heat Exchangers : Fast and sustainable leak testing technology for high energy efficiency products

    University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

    Author : Fritjof Nilsson; Yanjun Peng; [2023]
    Keywords : Leak rate; Optimization; Pressure Decay; Vacuum Technology; Volume; Läckhastighet; Optimering; Tryckfall; Vakuum Teknologi; Volym;

    Abstract : Background: One part of manufacturing a Plate Heat Exchanger (PHE) is to leak test them before delivery. Today, helium is used extensively in leak testing. How-ever, it is unsustainable to use helium in leak testing, because of its non-renewability and therefore becoming more and more expensive. Also, this technology is relatively complex. READ MORE

  3. 2. Status Mapping of tank to grave management of Low-GWP refrigerants.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Sandra Parra Gimeno; [2023]
    Keywords : Refrigerant; Blends; Synthetic low-GWP refrigerant; Natural refrigerant; Global Warming Potential GWP ; Tank-to-grave; Interviews.; Köldmedier; Blandning; Globalt uppvärmningspotential GWP ; Låg-GWP köldmedier; Naturligt köldmedier; installation till destruktion; Intervjuer.;

    Abstract : Refrigeration plays a vital role today in various residential, commercial, and industrial processes, requiring refrigerants to facilitate the cooling or heating processes. Over time, refrigerants have undergone significant changes to meet technological, social, environmental, and economic needs. READ MORE

  4. 3. Multivariate Time Series Data Generation using Generative Adversarial Networks : Generating Realistic Sensor Time Series Data of Vehicles with an Abnormal Behaviour using TimeGAN

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sofia Nord; [2021]
    Keywords : Time Series Data Generation; Generative Adversarial Network; Deep Neural Network; Data Augmentation; Synthetic Data Generation; Generering av Tidsseriedata; Generativa Motstridande Nätverk; Djupa Neurala Nätverk; Dataökning; Syntetisk Datagenerering;

    Abstract : Large datasets are a crucial requirement to achieve high performance, accuracy, and generalisation for any machine learning task, such as prediction or anomaly detection, However, it is not uncommon for datasets to be small or imbalanced since gathering data can be difficult, time-consuming, and expensive. In the task of collecting vehicle sensor time series data, in particular when the vehicle has an abnormal behaviour, these struggles are present and may hinder the automotive industry in its development.

  5. 4. Transfer Learning for Machine Diagnostics

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Abdul Aziz Al Chalati; Syed Asad Naveed; [2020]
    Keywords : Transfer Learning; Pneumatic System; Machine Learning; Deep Learning; Domain Adaptation;

    Abstract : Fault detection and diagnostics are crucial tasks in condition-based maintenance. Industries nowadays are in need of fault identification in their machines as early as possible to save money and take precautionary measures in case of fault occurrence. READ MORE

  6. 5. Early Warning Leakage Detection for Pneumatic Systems on Heavy Duty Vehicles : Evaluating Data Driven and Model Driven Approach

    University essay from KTH/Mekatronik

    Author : Christoffer Larsson Olsson; Erik Svensson; [2019]
    Keywords : Condition Based Maintenance; Predictive Maintenance; Leakage Detection; Data Driven; Model Driven; Tillståndsbaserat Underhåll; Prediktivt Underhåll; Läckagedetektering; Datadriven; Modelldriven;

    Abstract : Modern Heavy Duty Vehicles consist of a multitude of components and operate in various conditions. As there is value in goods transported, there is an incentive to avoid unplanned breakdowns. For this, condition based maintenance can be applied. READ MORE
