This technical report is an overview of work done on Headline Generation for written and broadcast news. The report covers HMM Hedge, a statistical approach based on the noisy channel model, Hedge Trimmer, a parse-andtrim approach using linguistically motivated trimming rules, and Topiary, a combination of Trimmer and Unsupervised Topic Discovery. Automatic evaluation of summaries using ROUGE a...

We analyze the notion of guessing model, a way to assign combinatorial properties to arbitrary regular cardinals. Guessing models can be used, in combination with inaccessibility, to characterize various large cardinals axioms, ranging from supercompactness to rank-to-rank embeddings. The majority of these large cardinals properties can be defined in terms of suitable elementary embeddings j : ...

Users are normally authenticated via their passwords in computer systems. Since people tend to choose passwords that can be easily remembered, the systems are under the threat of guessing attacks. Many authentication and key distribution protocols have been proposed to protect user passwords from guessing attacks. However, these protocols either are limited to some specific environments or incu...

We consider various versions of the 4 principle. This principle is a known consequence of 0. It is well known that or is not sensitive to minor changes in its definition, e.g.. changing the guessing requirement form "guessing exactly" to "guessing module a finite set". We show however. that this is not true for 4. We consider some other variants of 4 as well. ?

A script independent character segmentation from word images technique has been reported here. Word to character segmentation is an important preprocessing step of optical character recognition process. But in case of handwritten text, presence of touching characters decreases the accuracy of the technique of the segmentation of the characters from the word. In this paper, segmentation of handw...

In closed or open economy models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. We analyze this result in the context of developing economies, where a large proportion of households are credit constrained and the share of food expenditures in total consumption expenditures is high. We develop an open eco...

Recent initiatives to hold back cross-border mergers and acquisitions for ‘strategic’ reasons have made headline news. We discuss whether the initiatives may mark the start of a new protectionist era. We argue that standard globalization indicators show no such signs. However, an increasing divergence of incomes and increased insecurity might raise resistance against the globalization process. ...

The problem of guessing a random string is studied. It arises in the analysis of the strength of secret-key cryptosystems against guessing attacks. Expected number of guesses, or more generally moments of the number of guesses needed to break the cryptosystem grow exponentially with the length of the string. This thesis studies the rate of exponential growth of these moments using the theory of...
