Analysis of some simple stabilizers for physically obfuscated keys
Physically Obfuscated Keys (POK) are used to embed in chips secret bit-strings to be used in cryptographic protocols. Usually a POK is built as an array of elementary 1-bit POKs (cells). In order to guarantee tha...

Low-Complexity Classification Algorithm to Identify Drivers’ Stress Using Electrodermal Activity (EDA) Measurements
We present a system where a simple and low-complexity classification algorithm is used to identify the stress of a person while driving a car, using EDA Skin Potential Response (SPR) measurements. An adaptive ...

Generalized Elias schemes for efficient harvesting of truly random bits
The problem of generating a sequence of true random bits (suitable for cryptographic applications) from random discrete or analog sources is considered. A generalized version, including vector quantization, of...

Making random permutations from physically unclonable constants
The recent availability of reliable schemes for physically unclonable constants (PUC) opens interesting possibilities in the field of security. In this paper, we explore the possibility of using PUCs to embed ...

PTFE Graft as a “Bridge” to Communicating Veins Maturation in the Treatment of an Intrahepatic Cholangiocarcinoma Involving the 3 Hepatic Veins. The Minor-but-Complex Liver Resection
Parenchyma-sparing liver surgery allows resecting hepatic veins (HV) at the hepatocaval confluence with minor (<3 adjacent segments) liver resections. PTFE graft can be used as a bridge to communicating-veins ...

Performance evaluation of wavelet-based distributed video coding schemes
In this paper we propose and compare different distributed video coding (DVC) schemes based on the use of the wavelet transform, which naturally allows for spatial and other forms of scalability. In particular...

Designing local orthogonal bases on finite groups II: Nonabelian case
We extend to general finite groups a well-known relation used for checking the orthogonality of a system of vectors as well as for orthogonalizing a nonorthogonal one. This in turn, is used for designing local...

Local orthogonal bases I: Construction
We present a new method for constructing local orthogonal bases, both in continuous and discrete time. All basis functions are obtained from a single prototype window, and there exists a fast algorithm for imp...

Local orthogonal bases II: Window design
In the first part of this work we presented a technique to find a local orthogonal basis for a given vector space. The concept of a local orthogonal basis can be seen as an extension of the one-dimensional loc...
