Real-Time Location Systems (RTLS) have become very popular in recent years. These systems provide a contemporary layer of automation named automatic object location detection. Location measurements involve the transmission and reception of signals between hardware components of a system. A RTLS consists of at least two separate hardware components: a signal transmitter and a measuring unit. The...

The problem visual place recognition is commonly used strategy for localization. Most successful appearance based methods typically rely on a large database of views endowed with local or global image descriptors and strive to retrieve the views of the same location. The quality of the results is often affected by the density of the reference views and the robustness of the image representation...

This paper presents a novel Real-Time Localisation System (RTLS) based upon 2.45 GHz Surface Acoustic Wave (SAW) Radio Frequency Identification (RFID) systems. The system utilises a novel localisation method that combines the angular rotation of the RFID reader’s antenna system with the inherent Time-of-Flight (TOF) distance measurement capabilities of the SAW RFID system. The system design res...

It is common practice to fold pressure-time diagrams of compressors into pressure-volume diagrams because the latter are of special thermodynamic significance. For example, the enclosed area represents piston work. The folding is accomplished utilizing knowledge of the top dead center position and kinematic relationships of the compressor. It was found that even a small measurement error of the...

Bicycle sharing programs have emerged as a global trend as an affordable, convenient, and sustainable travel option with various benefits. One of the benefits of such programs is touted to be their positive impacts on transit ridership by extending transit catchment area and providing much needed last-mile connection. Thus, locating bicycle sharing programs in transit station areas is believed ...

Process mining is a rapidly developing field that aims at automated modeling of business processes based on data coming from event logs. In recent years, advances in tracking technologies, e.g., RealTime Locating Systems (RTLS), put forward the ability to log business process events as location sensor data. To apply process mining techniques to such sensor data, one needs to overcome an abstrac...
