  1. 11. Attitudes Towards Log4j : A Sentiment Analysis Study on Twitter Data

    University essay from Uppsala universitet/Institutionen för informatik och media

    Author : Isabelle Froissart; Julia Ring; [2022]
    Keywords : Sentiment; attitude; Twitter; sentiment analysis; Log4j; opinion;

    Abstract : A major security risk with the use of a Java logging library called Log4j was discovered in November 2021. The vulnerability meant that all Java applications using Log4j could be exploited by hackers through remote code execution. READ MORE

  2. 12. A comparison of energy usage between LoRa 433Mhz and LoRa 868MHz

    University essay from Jönköping University/JTH, Avdelningen för datavetenskap

    Author : Kevin Johansson; Christoffer Eklund; [2021]
    Keywords : LoRa; Internet of things; Data rate; Energy usage;

    Abstract : The number of devices connected to the internet is constantly increasing and therefore putting more weight on the importance of low energy usage. LoRa which is the physical part of the LoRaWAN communication protocol that this paper focuses on is popular in the area of IoT because of its low energy usage. READ MORE

  3. 13. Improving Transformer-Based Molecular Optimization Using Reinforcement Learning

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : PoChun Chang; [2021]
    Keywords : molecular optimization; transformer; nlp; natural language processing; ai; drug discovery; machine learning; deep learning;

    Abstract : By formulating the task of property-based molecular optimization into a neural machine translation problem, researchers have been able to apply the Transformer model from the field of natural language processing to generate molecules with desirable properties by making a small modification to a given starting molecule. These results verify the capability of Transformer models in capturing the connection between properties and structural changes in molecular pairs. READ MORE

  4. 14. Towards observing HH with ATLAS: ZH production and assessing theoretical uncertainties

    University essay from KTH/Fysik

    Author : Jonatan Gisslén; [2021]
    Keywords : ;

    Abstract : Even though the Standard Model of particle physics represents one of the triumphs of modern physics and seems to predict the outcome of any collision experiment, it has several shortcomings and therefore needs to be extended. After the discovery of the Higgs boson, one of the main aims of experimental particle physics is to probe the Standard Model for measurements that deviate from predictions, as this would imply new physics.

  5. 15. Delayed-acceptance approximate Bayesian computation Markov chain Monte Carlo: faster simulation using a surrogate model

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Andrea Krogdal; [2020-01-09]
    Keywords : ABC; MCMC; delayed acceptance; DA; surrogate model;

    Abstract : The thesis introduces an innovative way of decreasing the computational cost of approximate Bayesian computation (ABC) simulations when implemented via Markov chain Monte Carlo (MCMC). Bayesian inference has enjoyed incredible success since the beginning of 1990’s thanks to the re-discovery of MCMC procedures, and the availability of performing personal computers. READ MORE
