Alice wants to query a database but she does not want the database to learn what she is querying. She can ask for the entire database. Can she get her query answered with less communication? One model of this problem is Private Information Retrieval, henceforth PIR. We survey results obtained about the PIR model including partial answers to the following questions. (1) What if there are k non-c...

In the past few years several papers showed, that various generative mechanisms in formal language theory that use insertion and deletion operations are capable of generating any recursively enumerable languages [1, 2, 3, 4, 5, 6, 7, 8, 9]. Since such systems are also models of molecular computing, for practical reasons it is important to examine these systems in a restricted case, in which the...

Since most of the concepts and areas of research relevant to this thesis are related to fundamental data management issues (abstraction and representation) an appropriate start for this background analysis is to explain these fundamental issues. In the general case, the concepts of abstraction and representation are the means for us to perceive and interact with data in the most suitable manner...

T-S FUZZY MODEL-BASED MEMORY CONTROL FOR DISCRETE-TIME SYSTEM WITH RANDOM INPUT DELAY

A memory control for T-S fuzzy discrete-time systems with sto- chastic input delay is proposed in this paper. Dierent from the common assumptions on the time delay in the existing literatures, it is assumed in this paper that the delays vary randomly and satisfy some probabilistic dis- tribution. A new state space model of the discrete-time T-S fuzzy system is derived by introducing some stocha...
