An Energy-Harvesting Facade Optimization System for Built Environments

Daylighting is the immediate exploitation of solar energy in the form of nat-<br/>ural lighting and plays an integral role in minimizing the energy footprint<br/>of a building. Smart daylighting enables us to design buildings that provide<br/>comfort and energy savings.<br/><br/>This work proposes a dynamic facade system for buildings which aims...

Kernel isolation of a Capability-based security Operating System

Providing more confidentiality by extending a capability-based OS trough a hardware enforced isolation between the memory of the kernel and other memory. By employing memory tagging and hardware based Inter Process Communication (IPC) this defense gives an overhead of 26 percent.

Passive Localization of Robots with Ambient Light

A lot of research is been being done on Visible Light Communication (VLC), which has shown to be of interest for many applications, such as localization. Since localization based on VLC requires active modulation of light sources, this limits the amount of light sources that can be used for localization. Furthermore, in some situations there...

Intermittent Kernel: A First Attempt

Energy harvesting and battery-free sensing devices show great promise for revolutionizing computing in every known area while expanding to non-conventional use-cases. The promise of cheap, dense, and ubiquitous sensing technology brings new applications for the Internet of Things. However, the future programming model is blurry and complex. With...

Development of a Low-Cost, Solid-State, Line-Laser Distance Sensor: An Integrated Approach

Many robotic systems rely on laser ranging sensors to navigate and map their environment. As robots are getting more advanced, smaller and cheaper, their sensors need to decrease in size and cost, while increasing their reliability and accuracy. Current laser-based sensors have difficulty to meet these properties. They are either large,...

Computing the Vulnerability of Communication Networks to Large-Scale Disasters

Our society is becoming more and more dependent on communication networks. Thus, network operators and designers need to properly prepare themselves against large-scale disasters that could take down a significant amount of networking hardware within a large area.<br/><br/>In this work, we consider the vulnerability of a network to disasters,...

Phase Cancellation and Range Extension in Backscatter Networks

Progress has been made recently in the research of equal hierarchy backscatter communications. There are, however, challenges to overcome before this technology can become mainstream. For example, state-of-the-art solutions to the phase cancellation problem that occurs in such networks are still trivial and sub-optimal, especially in terms of...

Adapting TCP/IP protocol to a Time-Slotted NFC Channel present in a Wireless Power Environment

Kitchen is becoming a hotbed for innovation in the Internet of Things (IoT) revolution. Many kitchen appliances are being connected to the Internet to facilitate `smart-cooking'. The appliances are becoming cordless too, i.e., they are being powered by the inductive power sources which are integrated into the kitchen counter-tops. The Wireless...

Evolving State Machines as Robot Controllers

Automated generation of robot controllers using an Evolutionary Algorithm(EA) has received increasing attention in the last years as it has the potentialfor a reduction in the development time of a robot. Often these EAs generateNeural Networks (NNs) as robot controllers. Using a NN for automaticallygenerating robot controllers has two important...
