We introduce ChalametPIR: a single-server Private Information Retrieval (PIR) scheme supporting fast, low-bandwidth keyword queries, with a conceptually very simple design. In particular, we develop a generic framework for converting PIR schemes for ...

Filters trade off accuracy for space and occasionally return false positive matches with a bounded error. Numerous systems use filters in fast memory to avoid performing expensive I/Os to slow storage. A fundamental limitation in traditional filters is ...

Filters, such as Bloom, quotient, and cuckoo, save space by maintaining an approximate representation of a set and occasionally returning false positives. Filters play a critical role in building modern dataintensive applications and are used across ...

The paper presents linear predictors and causal filters for discrete-time signals featuring some different kinds of spectrum degeneracy. These predictors and filters are based on approximation of ideal noncausal transfer functions by causal ...

A critical aspect of modern key-value stores is the interaction between compaction policy and filters. Aggressive compaction reduces the on-disk footprint of a key-value store and can improve query performance, but can reduce insertion throughput because ...

Lifelogging is traditionally used for memory augmentation. However, recent research shows that users’ trust in the completeness and accuracy of lifelogs might skew their memories. Privacy-protection alterations such as body blurring and content deletion ...

Biomedical technologies help countless patients in improving the quality of managing health. The latest trend in biomedical engineering includes tissue bioengineering, biosensors, enhanced bone regeneration; and bioinstrumentation. ...

Auritus is an extendable and open-source optimization toolkit designed to enhance and replicate earable applications. Auritus serves two primary functions. Firstly, Auritus handles data collection, pre-processing, and labeling tasks for creating ...

Smart ear-worn devices (called earables) are being equipped with various onboard sensors and algorithms, transforming earphones from simple audio transducers to multi-modal interfaces making rich inferences about human motion and vital signals. However, ...

Log-Structured Merge-Tree (LSM-tree) based storage engines power numerous applications from social media to machine learning, networks, and Blockchain. Today, storage engine performance deteriorates as data increases especially for skewed workloads due ...

We investigate theoretically, the existence of several defects modes in the transmission spectrum and in the band structure of a one-dimensional star waveguide (SWG) structure. The perfect structure exhibits large photonic bands gaps (PBGs) that ...

Image data transfer has increased rigorously in the present times in social networking sites, mobile apps and live streaming video applications. This phenomenon puts enormous effect on internet bandwidth and speed of image transfer and loading. Image ...

Steerable filter pairs that are near quadrature have many image processing applications. This paper proposes a new methodology for designing such filters. The key idea is to design steerable filters by minimizing a departure-from-quadrature function. These ...

Today's filters, such as quotient, cuckoo, and Morton, have a trade-off between space and speed; even when moderately full (e.g., 50%-75% full), their performance degrades nontrivially. The result is that today's systems designers are forced to choose ...

The variation points in software architecture arise as a result of the availability of large number of filters and component libraries. An integration of different architectural styles is crucial and necessary in the development of large‐scale software ...

The use of the C programming language in a Linux programming course---common in most undergraduate computer science programs---has been the standard practice for nearly thirty years. The use of C is appropriate because Linux is written in C and, thus, ...

Foot print, a distinct parameter, is commonly associated with biometrics. Though several methods have been developed in the field of automated biometric based identification, foot print recognition has different characteristics and plays a pivotal role ...

We propose standard object out, an object-oriented analog to the output part of the Unix standard input output library.

Polymorphic Write Streams (PWS) act as architectural adapters between the object-oriented architectural style and the pipes and ...

With the rapid development of Internet finance, credit scoring has played a significant role in peer to peer lending platforms. However, the massive and high-dimensional characteristics of the credit data make it difficult to directly build the credit ...

The abundance of automatically-triggered lifelogging cameras is a privacy threat to bystanders. Countering this by deleting photos limits relevant memory cues and the informative content of lifelogs. An alternative is to obfuscate bystanders, but it is ...
