Location information is an important enabler for context-aware services and communication system improvement. Localization can be performed by comparing the power readings of all surrounding wireless transmitters to a database of these readings at all possible locations, known as the radio map. For this localization process to work, the system requires accurate radio maps. Our […]

In general, if a user is not willing/able to implement himself the solution, attaching sensor and actuator equipment to a computer typically leads to disproportionately expensive  purchases of proprietary hardware or software, which often still requires a considerable time investment. The goal of our planned company is to provide affordable computer-attached electronic equipment to individuals […]

The ever growing market demands for higher data rates and more reliable communication are the main drivers behind the technological growth in the wireless telecommunications industry. This R&D project aims to address an innovative technological shift from conventional wireless cellular networks to a paradigm of cooperative cellular networks that can potentially provide multiple-fold improvements in […]

Pulse shaping devices are the key elements for optical signal processing that are capable of reshaping the temporal waveform of optical pulses.  The applications of pulse shaping devices include ultrahigh-speed optical telecommunication, ultrafast all-optical computing and information processing, biomedical imaging, and electronic and photonic signal/device characterization and monitoring. For these applications, ultrafast optical waveform shapers […]

Solar power is one of the most promising renewable energy sources and its terrestrial abundance is several orders of magnitude higher than world’s consumption. Conventional solar cells, however, collect only a portion of solar energy – mostly visible sunlight. Our technology is capable of collecting the entire solar energy spectrum by using semiconducting nanocrystals (NCs) […]

In a typical scenario, a large heterogeneous software system, installed on many different sites and composed of several interacting components, exchanging data with several different protocols, must be updated to correct some defects, add new functionalities, or replace some obsolete components without breaking the system and while keeping its dependability. This research project aims at […]

Real-time systems are built as sets of components interacting with their environment. In most cases (including robotics, traffic control, manufacturing and industrial applications, etc.), these applications must satisfy "hard" timing constraints. If these constraints are not met, systems decisions (even correctly computed) can lead to catastrophic consequences for goods or lives. The development of real-time […]

In this project, a modified Delta parallel robot is designed in which the number of passive joints is reduced, and an active joint is added to the hardware. To the best of our knowledge, this configuration seems to be the first of its kind. In this project, kinematic and dynamic analyses will be performed. Active […]

Robot-assisted minimally invasive surgery is an emerging field in research and industry. A major challenge with the existing medical robotic systems (including the da Vinci® from Intuitive Surgical) is the lack of haptic feedback (sense of touch). On the other hand, medical imaging is only used for direct visualization in the existing systems. Certain surgical […]

Wireless communication devices have become an essential part of our lives and new ubiquitous applications are evolving rapidly. The spectrum of wireless links is limited and its efficient utilization via smart technology is very crucial to fulfill the ever increasing demand. Femtocell using a low-power home base station is a promising technique for serving indoor […]

Evolution of communication technology is pushing the limits beyond those of conventional radio frequency and millimeter-wave devices. A key trend in this evolution is miniaturization and ultrahigh density integration of radio/microwave frequency devices. Micro-electromechanical systems (MEMS) technology provides the opportunity to develop micro-scale RF devices and satisfy the market demand. This technology has made it […]

Fixed-rate coding for cooperative wireless networks with decode-and-forward (DF) relay processing has received much attention. Yet, only a fairly narrow body of research exists on rateless coded DF relaying networks. Little is known about how the performances and complexity implications of fixed-rate and rateless coded systems compare. Meanwhile, such comparisons play a vital role in […]
