Theoretical Studies of Atomic Structure, Radiative Transitions and Interference Effects

Theoretical calculations concerning the advanced understanding of atomic structure and transitions has been performed for some atomic systems. The importance of different types of correlation depending on system has been investigated both using relativistic and non-relativistic quantum mechanics. Methods for simplifying the analysis of special types of spectra is presented and transition rates and

A note on distinguishing attacks

A new distinguishing attack scenario for stream ciphers, allowing a resynchronization collision attack, is presented. The attack can succeed if the part of the state that depends on both the key and the IV is smaller than twice the key size. It is shown that the attack is applicable to block ciphers in OFB mode. For OFB mode, the attack is more powerful than the previously known generic distinguis

On the Efficient Frequency Estimation of a Single Tone

The frequency estimation of a single tone corrupted by additive white Gaussian noise has received significant attention over the last decades due to its wide applicability in signal processing. In this paper, we propose a computationally fast and statistically improved hybrid single tone estimator which outperforms other recently proposed approaches, lowering the signal-to-noise ratio at which the

Den (o)hållbara förpackningen

I Den [o] hållbara förpackningen analyseras svenska konsumentförpackningar från 1930-talet fram till idag. Boken består av tre delar där läsaren först får lära känna mjölkförpackningarna, som är livsmedelsbranschens kanske vanligaste men samtidigt mest krävande förpackning. Därefter behandlas läkemedelsförpackningarna, en kategori som alltid har kännetecknats av ett högt säkerhetstänkande. Slutlig
