Intuition. Suppose that your lecturer writes the number 25927 on the board and asks everyone in the class for its prime factorisation. Immediately Alice, who is incidentally a friend of the lecturer, shouts 11 × 2357. What conclusion can be drawn from this? Can we conclude that Alice is very good at factoring integers? It might haven been the case that Alice’s favourite primes are 11 and 2357 a...

This type of game was introduced by Bodlaender [2]. He considers a variant, which we will call game g, in which Alice must move first and passing is not allowed. In order to obtain upper and lower bounds for a parameter associated with game g, two other variants are useful. In the game B Bob may move first. He may also miss one or several turns, but Alice must always move. In the other variant,...

In previous studies, we have used quantitative methods to examine the effectiveness of the Alice programming language in terms of student enjoyment, confidence, and learning outcomes. However, in terms of the overall quality of a learning experience, quantitative measures provide only part of the story. This paper reports on the use of Alice from a student perspective using qualitative data gat...

Consider three players Alice, Bob and Cath who hold a, b and c cards, respectively, from a deck of d = a+ b+ c cards. The cards are all different and players only know their own cards. Suppose Alice and Bob wish to communicate their cards to each other without Cath learning whether Alice or Bob holds a specific card. Considering the cards as consecutive natural numbers 0, 1, ..., we investigate...

beryllium chemical combination has a considerable effect on the design and fabrication of the241am9be neutron source. in this investigation the beryllium combinations were studied as a generator ofneutrons with various mass percentage, and the neutron yields were also calculated using the results of thealice and srim codes calculations per unit incident charge. the neutron yields of beryllium ...

Alice and Bob are connected via a two-way binary channel. This paper describes an algorithm to enable Alice to send a message to Bob when 1) an oblivious adversary flips an unknown number of bits, T , on the channel; and 2) the message length L, and a desired error probability, ǫ are public knowledge. With probability at least 1− ǫ, our algorithm ensures that Bob receives the correct message, a...

This paper describes how NOMLEX, a dictionary of nominalizations, can be used in Information Extraction (IE). This paper details a procedure which maps syntactic and semantic information designed for writing an IE pattern for an active clause (IBM appointed Alice Smith as vice president) into a set of patterns for nominaliza-tions (e.g., IBM's appointment of Alice Smith as vice president and Al...

In this work we study the problem of confidential communication when different resources of randomness are available. We start with the relay channel where source observations are available at each terminal. We study the scenario where the transmitter (Alice) sends a private message to the destination (Bob), which is confidential to the relay (Eve). Alice and Bob also want to agree on a secret ...
