Towards Sensor Database Systems
TLDR
This paper defines the concept of sensor databases mixing stored data represented as relations and sensorData represented as time series, and describes the design and implementation of the COUGAR sensor database system.
LightNVM: The Linux Open-Channel SSD Subsystem
TLDR
The experience of building LightNVM, the Linux Open-Channel SSD subsystem, is presented and a new Physical Page Address I/O interface that exposes SSD parallelism and storage media characteristics is introduced, which integrates into traditional storage stacks, while also enabling storage engines to take advantage of the new I-O interface.
Querying the physical world
TLDR
An abstraction is defined that allows to represent a device network as a database and how distributed query processing techniques are applied in this new context of a device database system is described.
Linux block IO: introducing multi-queue SSD access on multi-core systems
TLDR
This work describes the design of a next generation block layer that is capable of handling tens of millions of IOPS on a multi-core system equipped with a single storage device, and shows that the design scales graciously with the number of cores, even on NUMA systems with multiple sockets.
uFLIP: Understanding Flash IO Patterns
TLDR
This paper defines uFLIP, a benchmark for measuring the response time of flash IO patterns, and presents a benchmarking methodology which takes into account the particular characteristics of flash devices.
Adaptive and Decentralized Operator Placement for In-Network Query Processing
TLDR
An adaptive and decentralized algorithm that progressively refines the placement of operators by walking through neighbor nodes is described, which can achieve near optimal placement onto various graph topologies despite the risks of local minima.
Computational reproducibility: state-of-the-art, challenges, and database research opportunities
TLDR
This tutorial will present a series of guidelines and, through hands-on examples, review existing tools to help authors create of reproducible results and outline open problems and new directions for database-related research having to do with querying computational experiments.
Bluetooth and sensor networks: a reality check
TLDR
The results show that despite obvious limitations the Bluetooth sensor nodes the authors studied exhibit interesting properties, such as a good energy per bit sent ratio, and this reality check underlies the limitations and some promises of Bluetooth for the sensor network regime.
Minimal invariant varieties and first integrals for algebraic foliations
Abstract.Let X be an irreducible algebraic variety over ℂ, endowed with an algebraic foliation $$ {\user1{\mathcal{F}}} $$. In this paper, we introduce the notion of minimal invariant variety V($$
