Signal Processing’s Impact on Wearable Technology in Healthcare Monitoring

By: 
Dr. Rahul Kher

Wearable sensor technology has improved substantially in recent years – and the personalized healthcare movement is reaping the benefits. Specifically, advancements in miniaturization, smart materials, low-power consumption and ruggedness have transformed ubiquitous monitoring. Monitoring vital physiological parameters including body temperature, heart rate, blood pressure, sugar level, and oxygen saturation in blood is now standard – and affordable.  Today’s increasingly compact, wearable designs incorporate and leverage numerous sensors: accelerometers, SpO2, (an estimate of oxygen saturation in the blood), heart/pulse rate, electrocardiography (ECG), and electroencephalography (EEG), among them. Signal processing plays a significant role too; techniques applied on the acquired sensor data – real-time and off-line – continue to enhance the value, and progress, of healthcare monitoring, which is crucial for use by the public.

Automation is Coming to Research

By: 
Dr. Pavel Loskot, Senior Lecturer, Swansea University

The rapid advancement and proliferation of information and communication technologies (ICT) in the past two decades significantly impacted how we do research. For instance, our research increasingly relies on growing computing power and storage capacity to gather and process the constant production of data - our observations of systems and phenomena we would like to understand, control, and improve. To turn these observations into useful knowledge, findings, discoveries, and better decisions, the data needs to be intelligently processed, and the results of such processing suitably visualized. 

In research communities, the process of obtaining, processing and visualizing data to yield new insights is usually captured and shared in scientific papers. The papers often cite other papers in order to connect new findings with previous findings. This creates an intricate web of interlinked papers comprising most of our scientific knowledge. The web of papers is already very large and growing exponentially. It’s difficult to search and navigate - and easy to continually rediscovering things we already know.

In 2008, United Airlines baggage handlers in Chicago severely damaged Dave Carroll’s Taylor guitar worth $3,500. After nine months of unsuccessful pleas for compensation, Carroll wrote the song "United Breaks Guitars” – a YouTube hit with more than 17 million views. Four weeks later, the airline’s stock fell about 10 percent for a loss of $180 million.

How Signal Processing Supports Multibiometric Systems and Makes them More Secure

By: 
Rohitkumar Thanki

When you first hear the word “biometric,” it’s likely you make the connection to human beings. By definition, biometric means “life to measure.” There are many types of biometric characteristics, such as fingerprints, faces, eyes, speech and palmprints. Commonly used for individual recognition and authentication, these biometric characteristics comprise the biometric system.

The Science Behind Music: How Dıgial Signal Processing Powers Our Favorite Tunes

By: 
Dr. Ibrahim Atakan KUBİLAY

What if we lived in a world without music?  It’s utterly unthinkable. Music has long been an important part of human life.  Researchers found human remain alongside flutes made from animal bones dating more than 40,000 years ago1.  In ancient Greek mythology, muses were goddesses or water nymphs, inspiring humans in the fields of art and science, and spurring incredible developments2.
