This paper describes Haystack, an object storage system optimized for Facebook's Photos
application. Facebook currently stores over 260 billion images, which translates to over 20 …

A logic circuit is said to be combinational if the function it computes depends only on the
inputs applied to the circuit, and is sequential if it depends on some past history in addition …

There is growing recognition of the need to address the fragility of digital information, on
which our society heavily depends for smooth operation in all aspects of daily life. This has …

This book provides insights into how to approach and utilise data science tools,
technologies, and methodologies related to artificial intelligence (AI) in industrial contexts. It …

Object storage systems are a flexible class of storage where data are architectured and
stored in the form of units called objects. Objects may store structured, semi-structured or …

In today's Grids, files are usually managed by Grid data management systems that are
superimposed on existing file and storage systems. In this paper, we analyze this …

The provisioning of an efficient ultra-large scalable distributed storage system for expanding
cloud applications has been a challenging job for researchers in academia and industry. In …

We propose a novel object detection framework for partially-occluded small instances, such
as pedestrians in low resolution surveillance video, cells under a microscope, flocks of small …

Scientific data sets, which grow rapidly in volume, are often attached with plentiful metadata,
such as their associated experiment or simulation information. Thus, it becomes difficult for …

Virtual disks are the main form of storage in today's virtual machine environments. They offer
many attractive features, including whole system versioning, isolation, and mobility, that are …
