As the traditional eutectic SnPb solder alloy has been outlawed, the electronic industry has almost completely transitioned to the lead-free solder alloys. The conventional SAC305 solder alloy used in lead-free electronic assembly has a high melting and processing temperature with a typical peak reflow... READ MORE
Traditional embedded systems such as secure smart cards and nano-sensor networks have been utilized in various usage models. Nevertheless, emerging secure deeply-embedded systems, e.g., implantable and wearable medical devices, have comparably larger “attack surface”. Specifically, with respect to medical devices, a security breach can... READ MORE
Vehicle tracking from an aerial platform poses a number of unique challenges including the small number of pixels representing a vehicle, large camera motion, and parallax error. For these reasons, it is accepted to be a more challenging task than traditional object tracking and... READ MORE
The performance of Indium Gallium Zinc Oxide (IGZO) Thin-Film Transistors (TFTs) has improved significantly in recent years; however, device stability still remains a significant issue. In bottom-gate TFTs a difficult challenge is the lack of gate control on the back-channel region, resulting in distortion in... READ MORE
Consider the airfoil: a carefully designed structure capable of stable lift in a uniform air flow. It so happens that air pressure and radiation (light) pressure are similar phenomena because each transfer momentum to flow-disturbing objects. This, then, begs the question: does an optical...

The ability of structural genomics consortia to determine protein structures more quickly than the proteins can be functionally annotated by conventional experimental means has generated a significant bottleneck that inhibits the progress of certain areas of biological and medical research. This issue is currently... READ MORE
Facial videoplethysmography provides non-contact measurement of heart activity based on blood volume pulsations detected in facial tissue. Typically, the signal is extracted using a simple webcam followed by elaborated signal processing methods, and provides limited accuracy of time-domain characteristics. In this study, we explore...
