Pujol Gil, Enric (2017)

The World Wide Web has become the most used information system worldwide. It has fueled an unprecedented commercialization of the Internet by turning this network system designed for academic data ...

Multi-factor authentication based on movement and gesture

Roshandel, Mehran (2017)

Security and usability are in constant touch with each other. It is in the nature of security methods that, the more secure they are, the more they complicate interactions. Yet users dislike using ...

User experience with mobile security and privacy mechanisms

Kraus, Lydia (2017)

Smartphones have become indispensable in the life of many people. They are constant companions, connections to the world, information sources, and substitutes for other devices and tools that had...

Towards energy aware wireless network operation

Pollakis, Emmanuel (2017)

Todays cellular communication networks have come a long way from voice only capabilities to wireless networks that serve millions of users and machine type devices with high data rates and low late...

Fiber optical parametric amplifiers in optical communication systems

Marhic, Michel E.; Andrekson, Peter A.; Petropoulos, Periklis; Radic, Stojan; Peucheret, Christophe; Jazayerifar, Mahmoud (2015)

The prospects for using fiber optical parametric amplifiers (OPAs) in optical communication systems are reviewed. Phase-insensitive amplifiers (PIAs) and phase-sensitive amplifiers (PSAs) are consi...

Security by similarity: information-theoretic secrecy and decentralized detection algorithms for wireless networks

Mohammadi, Jafar (2017)

The broadcasting attribute of the wireless communication channel poses severe security vulnerabilities since any adversary node in the range of reception is able to listen as well as to disrupt the...

Strengthening system security on the ARMv7 processor architecture with hypervisor-based security mechanisms

Vetter, Julian (2017)

The computing landscape has significantly changed over the last decades. The devices we use today to interact with digital content have shifted away from stationary computers towards ubiquitous net...

Liquid phase crystallized silicon on sinusoidal textured glass substrates

Köppel, Grit (2017)

The aim of this thesis is to identify a light trapping scheme for liquid phase crystallized silicon thin-film solar cells providing anti-reflective properties in the wavelength range of interest an...

Contactless visible light probing for nanoscale ICs through 10 μm bulk silicon

Boit, Christian; Lohrke, Heiko; Scholz, Philipp; Beyreuther, Anne; Kerst, Uwe; Iwaki, Y. (2015)

This paper explains why only optical techniques will be able to provide debug and diagnosis of bulk silicon FinFET technologies. In order to apply optical techniques through a convenient thickness ...

Nanocrystalline silicon and silicon oxide contact layers for silicon heterojunction solar cells

Mazzarella, Luana (2017)

Crystalline-silicon solar cells are presently the main technology to supply the rapidly growing market for competitive photovoltaic electricity. To drive conversion efficiency of such cells further...

Gesture-based user authentication on mobile devices using accelerometer and gyroscope

Guse, Dennis (2017)

Mobile devices offer their users lots of possibilities and a feeling of freedom. However, this freedom comes along with new security threats. Sensitive data might be stolen and abused, if an unauth...

Design and provability of a statically configurable hypervisor

Nordholz, Jan (2017)

In this thesis we develop a novel, minimalist design for Type I hypervisors and present a fully working prototype for the ARMv7 and ARMv8 architectures. We introduce its key design paradigm, the Pr...

Energy savings in 5G automotive nomadic relaying networks

Ren, Zhe (2017)

The requirements of ubiquitous connectivity of high speed data access create fundamental challenges for the design of future wireless communication systems and modern vehicle telematic systems. Aga...

Medical image analysis of gastric cancer in digital histopathology: methods, applications and challenges

Sharma, Harshita (2017)

Medical image analysis in digital histopathology is a currently expanding and exciting field of scientific research. In this work, histopathological image analysis is extensively studied and a syst...

Ultrasonic flow metering with highly accurate jitter and offset compensation

Hamouda, Assia (2017)

This thesis proposes a new method for measuring water flow with a transit time ultrasonic flow meter device. The developed method allows the ultrasonic flow meter to reach a better performance than...

Messtechnische Bewertung weißer LED-Leuchten

Bensel, Silvia (2017)

Mit dem Einzug der LED (engl. Light Emitting Diode) in die Allgemeinbeleuchtung wächst der Bedarf an einer vollständigen Charakterisierung moderner Lampen und Leuchten. Dies erfordert die Entwicklu...

Nonlinear spike-and-slab sparse coding for interpretable image encoding

Shelton, Jacquelyn A.; Sheikh, Abdul-Saboor; Bornschein, Jörg; Sterne, Philip; Lücke, Jörg (2015)

Sparse coding is a popular approach to model natural images but has faced two main challenges: modelling low-level image components (such as edge-like structures and their occlusions) and modelling...

Call Graph Generated by Simulation-Based Tracing and Profiling

Busse, Anselm; Karnapke, Reinhardt; Parzyjegla, Helge (2017)
