Before integration in the ALICE experiment, the readout chambers of the ALICE-Transition-RadiationDetector (TRD) [1] are tested at the Institut für Kernphysik Frankfurt (IKF), including measurements of their gas amplification factor. In this report, we describe the revisal of these test-procedures by introducing additional measurements to ensure a self-consistent determination of the absolute g...

Leading hadron azimuthal angular correlations in the ALICE central barrel are studied with the HIJING event generator employing scenarios with and without inmedium jet quenching. We investigate the potential of leading hadron correlation studies in the high multiplicity environment of a Pb-Pb collision at √ sNN = 5.5 TeV in the central barrel of the ALICE detector.

The task of privacy amplification, in which Alice holds some partially secret information with respect to an adversary Eve and wishes to distill it until it is completely secret, is known to be solvable almost optimally in both the classical and quantum worlds. Unfortunately, when considering an adversary who is limited only by nonsignalling constraints such a statement cannot be made in genera...

The whitespace-discovery problem describes two parties, Alice and Bob, trying to discovery one another and establish communication over one of a given large segment of communication channels. Subsets of the channels are occupied in each of the local environments surrounding Alice and Bob, as well as in the global environment (Eve). In the absence of a common clock for the two parties, the goal ...

This paper investigates one-round secure computation between two distrusting parties: Alice and Bob each have private inputs to a common function, but only Alice, acting as the receiver, is to learn the output; the protocol is limited to one message from Alice to Bob followed by one message from Bob to Alice. A model in which Bob may be computationally unbounded is investigated, which correspon...

The ALICE Collaboration is an active member of the EDG (also known as DataGrid) project since the very beginning; it took active part in the definition of user requirements and detailed use cases, as well as in the evaluation of the EDG testbed, all along its evolution. In December 2001, ALICE ran the first application job on the testbed, the simulation of a low multiplicity Pb-Pb event at the ...

Consider the following practical scenario. Amother Alice would like to make her assets accessible only to her descen-dents. In order to do so, she encrypts her secret Swiss bank account with her DNA sequences, and provides this information to her descendents. To simplify the scenario and without losing generality, we assume that Alice has only one son, named Bob. Therefore, Alice provides the c...

In this paper we describe some results of the Alice project. Alice is an ontology based e-commerce project which aims to support online users in the task of shopping. Ontologies describing customers, products, typical shopping tasks and the external context form the basis for the Alice architecture. We also build upon two novel interface metaphors originally developed for navigating databases: ...
