1. 1. Security Assessment of IoT- Devices Grouped by Similar Attributes : Researching patterns in vulnerabilities of IoT- devices by grouping devices based on which protocols are running.

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Filip Sannervik; Parth Magdum; [2021]
   Nyckelord :Internet of Things IoT ; IoT-Devices; Vulnerability Assessment; Grouping IoT-Devices; Self-Organising maps; Vulnerability likelihood.; Sakernas Internet IOT ; IoT-Enheter; Bedömning av Sårbarhet; Gruppering av IoT-Inheter; Self-Organising maps SOMs ; Sårbarhetsrisk.;

   Sammanfattning : The Internet of Things (IoT) is a concept that is getting a lot of attention. IoT devices are growing in popularity and so is the need to protect these devices from attacks and vulnerabilities. Future developers and users of IoT devices need to know what type of devices need extra care and which are more likely to be vulnerable. LÄS MER

3. 2. Assessment of Machine Learning Applied to X-Ray Fluorescence Core Scan Data from the Zinkgruvan Zn-Pb-Ag Deposit, Bergslagen, Sweden

   Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

   Författare :Frans Filip Simán; [2020]
   Nyckelord :XRF; X-Ray Fluorescence; Core Scanning; Machine Learning; AI; SOM; Self Organising Map; CART; Classification and Regression Trees; K-means clustering; Rock Classification; Virtual Core Logging; Zinkgruvan;

   Sammanfattning : Lithological core logging is a subjective and time consuming endeavour which could possibly be automated, the question is if and to what extent this automation would affect the resulting core logs. This study presents a case from the Zinkgruvan Zn-Pb-Ag mine, Bergslagen, Sweden; in which Classification and Regression Trees and K-means Clustering on the Self Organising Map were applied to X-Ray Flourescence lithogeochemistry data derived from automated core scan technology.

4. 3. Assessment of hemodynamic parameters using 4D Flow MRI

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Mattias Andersson; [2018]
   Nyckelord :Hemodynamics; Hemodynamic Parameters; 4D Flow; 4D Flow MRI; Blood flow; Cardiac Disease; Heart Disease; MRI; Magnetic Resonance Imaging; Visualisation; Mathematics and Statistics;

   Sammanfattning : Heart disease is one of the worldwide leading causes of death, and facilitating the work of physicians in this area is therefore of great importance. Imaging of the heart is one of many fields that is used for diagnosis and analysis of cardiac disease. LÄS MER

5. 4. Improving Clustering of Gene Expression Patterns

   Magister-uppsats, Institutionen för datavetenskap

   Författare :Per Jonsson; [2000]
   Nyckelord :gene expression analysis; functional annotation; clustering techniques; self-organising maps;

   Sammanfattning : The central question investigated in this project was whether clustering of gene expression patterns could be done more biologically accurate by providing the clustering technique with additional information about the genes as input besides the expression levels. With the term biologically accurate we mean that the genes should not only be clustered together according to their similarities in expression profiles, but also according to their functional similarity in terms of functional annotation and metabolic pathway.
