   Abstract : Epilepsy affects more than 50 million people and is one of the most prevalent neurological disorders and has a high impact on the quality of life of those suffering from it. However, 70% of epilepsy patients can live seizure free with proper diagnosis and treatment. Patients are evaluated using scalp EEG recordings which is cheap and non-invasive. READ MORE

3. 2. Detection of Human Emotion from Noise Speech

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Sai Chandra Sekhar Reddy Nallamilli; Nihanth Kandi; [2020]
   Keywords : Neural Network; Activation Function; Fast Fourier Transform; Karhunen-Loeve Transform; speech enhancement; filtering; Wavelet Transform; Speech preprocessing; signal to noise ratio; shallow neural network;

   Abstract : Detection of a human emotion from human speech is always a challenging task. Factors like intonation, pitch, and loudness of signal vary from different human voice. So, it's important to know the exact pitch, intonation and loudness of a speech for making it a challenging task for detection. READ MORE

4. 3. Traffic Load Predictions Using Machine Learning : Scale your Appliances a priori

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

   Author : Michail Xirouchakis; [2018]
   Keywords : Network Function Virtualization; Software Defined Networking; Machine Learning; Predictions; Network Function Virtualization; Software Defined Networking; Maskininlärning; Prognoser;

   Abstract : Layer 4-7 network functions (NF), such as Firewall or NAPT, have traditionally been implemented in specialized hardware with little to no programmability and extensibility. The scientific community has focused on realizing this functionality in software running on commodity servers instead. Despite the many advancements over the years (e.g. READ MORE

5. 4. Processing of Optical Coherence Tomography Images : Filtering and Segmentation of Pathological Thyroid Tissue

   University essay from Linköpings universitet/Institutionen för medicinsk teknik; Linköpings universitet/Medicinska fakulteten

   Author : Daniela Koller; [2016]
   Keywords : ;

   Abstract : In the human body, the main function of the healthy thyroid gland is the regulation of the metabolism and hormone production. Included in the thyroid are organized structured and uniformly shaped follicles ranging from 50-500 μm in diameter. READ MORE

6. 5. Image Reconstruction using wavelet transform with extended fractional fourier Transform

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling
