HackRF One is a Software Defined Radio (SDR) peripheral capable of transmission or reception (half-duplex) of radio signals from 1MHz to 6GHz. This device is mostly designed for testing and development of modern and next generation radio technologies. It is an open source hardware platform that can be used as a USB peripheral or programmed for stand-alone operation. In the following experiment, i...
A small Preview of Epilepsy Seizure Prediction, What? How? Why?
Epilepsy is a chronic neurological disorder that affects approximately 50 million people worldwide. These intractable seizures postures are a serious risk of injury, restrict the self-sufficiency and mobility of a person. While medication and surgery can, to some degree, relieve the symptoms, these treatments fail to help all patients. Population wide, approximately 1% is suffering from epilepsy...
Bitcoin and the Greater fool theory
Warnings about bitcoins and other cryptocurrencies are coming from all directions. Concerns about the security of the cryptocurrency have continued to shadow it. Last year, almost 120,000 bitcoin worth around $78m (£58m)were stolen from Hong Kong-based Bitfinex, one of the most popular cryptocurrency exchanges, which resulted in a 20% drop in the value of the currency at the time. Moreover, there...

Self-Adaptive Orchestration of energy efficiency capabilities In Heterogeneous Systems
Dynamic resources allocation has become even more attractive as a research direction with commodity computing gaining momentum and bringing new requirements regarding elasticity and flexibility and with the growing importance of cloud computing. The aim is to deliver high-performance computational while leveraging on other aspects, such as energy consumption. Admittedly, heterogeneity comes at...
Principal Component Analysis using Matlab
PCA is a way of identifying patterns in data, and expressing the data in such a way as to highlight their similarities and differences. Below are the steps of the algorithm: close all; % clear all; clc; % data = load('Data/eeg.mat'); % data = data.data{1,2}; Step 1 – Initialize the dataset, 6 vectors of 32 sample data % % Step 1 - Initialize the dataset, 6 vectors of 32 sample data % X =...
Inverse Kinematics Algorithm for Pentapod (five-legged) robot
Inverse kinematics is a much more challenging problem than forward kinematics. It is the procedure when we have a desired end effector position but need to know the joint angles required to achieve it. The solution of the inverse kinematics is computationally expensive, and usually, it takes long time for the real time control of manipulators. Singularities and nonlinearities that make the...
Literature Review in Speech Emotion Recognition
Introduction Speech is one of the fastest and most natural ways of communication between humans. The speech signal contains not only the message but also necessary information like the emotions of the speaker [1]. Therefore, Speech emotion recognition (SER) is a research field that based on speech recognition but deals with the recognizing the emotional state of the speaker. Speech emotion...
Literature Review of Deep Machine Learning for feature extraction
Abstract Feature extraction is a crucial part of many tasks. In recent years, deep learning approaches have achieved significant importance as a way of constructing hierarchical representations from unlabeled data. Understanding how to recognize complex, high-dimensional data is one of the greatest requests of our time. Deep Machine Learning have showed us that there is an efficient and accurate...
Is Computer Science a Science?
Abstract In our times, there has been a tremendous evolution of technology that among others has extended human capabilities. This infiltration of technology in everyday life can be, at least at a high extent, attributed to computers and the development of computer science. In this paper, we examine the definition of science and the scientific method, and we try to justify the validity of the...
