Ambipolar Si Nanowire Field Effect Transistors for Low Current and Temperature Sensing

Giovanni De Micheli, Davide Sacchetto, Yusuf Leblebici

This paper reports on the fabrication and characterization of a pA current and temperature sensing device with ultra-low power consumption based on a Schottky barrier silicon nanowire transistor. Thermionic and trap-assisted tunneling current conduction me ...

Local Model Checking

Rachid Guerraoui, Maysam Yabandeh

Current approaches to model checking distributed systems reduce the problem to that of model checking centralized systems: global states involving all nodes and communication links are systematically explored. The frequent changes in the network element of ...

Repeater Insertion Techniques for 3D Interconnects

Giovanni De Micheli, Vasileios Pavlidis

A new approach for inserting repeaters in 3-D interconnects is proposed. The allocation of repeaters along an interplane interconnect is iteratively determined. The proposed approach is compared with two other techniques based on conventional methods used ...

An Information Theoretic Approach to Speaker Diarization of Meeting Recordings

Deepu Vijayasenan

In this thesis we investigate a non parametric approach to speaker diarization for meeting recordings based on an information theoretic framework. The problem is formulated using the Information Bottleneck (IB) principle. Unlike other approaches where the ...

A partition-free approach to transient and steady-state charge currents

We construct a non-equilibrium steady state and calculate the corresponding current for a mesoscopic Fermi system in the partition-free setting. To this end we study a small sample coupled to a finite number of semi-infinite leads. Initially, the whole sys ...

What role for minibus services in urban areas, in a European market segmentation approach

Regina Witter

In many European cities public transport, particularly busses, are unattractive and underused, due to the lack of direct connections, the need of transfers and the loss of time and comfort. Hence, this study aims at developing the business concept of an al ...

The Complexity of Distinguishing Distributions

Serge Vaudenay, Thomas Baignères

Cryptography often meets the problem of distinguishing distributions. In this paper we review techniques from hypothesis testing to express the advantage of the best distinguisher limited to a given number of samples. We link it with the Chernoff informati ...

A profiling framework for high level design space exploration for memory and system architectures

In 1971, the first microprocessor produced in mass production had 2300 transistor and was able to compute 60'000 operations per second at 740 kHz. Nowadays, even a common gaming console uses a central unit including 243 millions of transistors running at 4 ...

Reduced complexity attacks on the alternating step generator

Willi Meier, Shahram Khazaei, Simon Fischer

In this paper, we present some reduced complexity attacks on the Alternating Step Generator (ASG). The attacks are based on a quite general framework and mostly benefit from the low sampling resistance of the ASG, and of an abnormal behavior related to the ...
