CAPTURE: A Mobile Based Indoor Positioning System using Wireless Indoor Positioning System
International Journal of Interactive Mobile Technologies (iJIM), 2018 The existence of mobile devices as a location pointing device using Global Positioning System (GPS) is a very common thing nowadays. The use of GPS as a tool to determine the location of course has a shortage when used indoors. Therefore, the used of indoor location-based services in a room that leverages the use of Access Point (AP) is very important.

Forward‐Biased Perovskite Photodiodes for In‐Sensor Optical Change Sensing
Advanced Functional Materials, EarlyView.A forward‐biased perovskite photodiode is introduced as an in‐sensor analog preprocessing unit that uses current balancing between photocurrent and injection current to generate optical changes relative to programmable optical reference levels. The device directly converts reference‐relative optical changes into bipolar current signals, enabling sensor‐
