Abstract. Linear batch codes and codes for private information retrieval (PIR) with a query size t and a restricted size r of the reconstruction sets are studied. New bounds on the parameters of such codes are derived for small values of t or r by providing corresponding constructions. By building on the ideas of Cadambe and Mazumdar, a new bound in a recursive form is derived for batch codes a...

Private Information Retrieval (PIR), despite being well studied, is computationally costly and arduous to scale. We explore lower-cost relaxations of information-theoretic PIR, based on dummy queries, sparse vectors, and compositions with an anonymity system. We prove the security of each scheme using a flexible differentially private definition for private queries that can capture notions of i...

Spatial relationships are important ingredients for expressing constraints in retrieval systems for spatial databases. In this paper we propose a uniied representation of spatial relationships, 2D Projection Interval Relationships (2D-PIR), that integrates both directional and topological relationships. We propose a graph representation for pictures that is based on 2D-PIR. This graph represent...

The private information retrieval (PIR) primitive has received a significant amount of attention from the scientific community since it was first proposed by Chor et al. with other cryptographic primitives [6, 12] and improved upper bounds [3, 16] have been obtained. In this paper, we continue along this path and give an improved upper bound for information theoretic PIR. Our protocol and proof...

PIWI-interacting RNAs (piRNAs) are thought to silence transposon and gene expression during development. However, the roles of piRNAs in somatic tissues are largely unknown. Here we report the identification of 555 piRNAs in human lung bronchial epithelial (HBE) and non-small cell lung cancer (NSCLC) cell lines, including 295 that do not exist in databases termed as piRNA-like sncRNAs or piRNA-...

Software as a Service (SaaS) is one of the delivery model of cloud computing in which service are provided by the service providers and client make use of it through Internet. Here we present a saas in pcloud. pcloud is a distributed system which contains a number of cooperated nodes. In pcloud, distribute the programming software to a number of nodes so that queries can be executed in parallel...

This article describes a system for measuring temperature by monitoring an object’s radiation in the infrared spectrum. Using a measuring device by passing through a data acquisition interface, a long-term observation of the temperature variance of objects on a personal computer by the LabVIEW software is conducted. A special mechanism joined with a pyroelectric infrared ~PIR! sensor, optical c...
