A hierarchical indexing strategy for optimizing Apache Spark with HDFS to efficiently query big geospatial raster data

open access: yesInternational Journal of Digital Earth, 2020
Earth observations and model simulations are generating big multidimensional array-based raster data. However, it is difficult to efficiently query these big raster data due to the inconsistency among the geospatial raster data model, distributed ...

A Maude specification of the Kademlia distributed hash table: centralized version [PDF]

open access: yes, 2017
Kademlia is the most popular peer-to-peer distributed hash table (DHT) currently in use. It offers a number of desirable features that result from the use of a notion of distance between objects based on the bitwise exclusive or of n-bit quantities that ...

Laser Synthesis in Liquid Induced Lattice Distortion in PtFeSn/Activated Carbon for Enhanced Methylcyclohexane Dehydrogenation

open access: yesSmall Methods, EarlyView.
A Pt‐Fe‐Sn alloy catalyst supported on activated carbon is synthesized via laser synthesis in liquid, introducing lattice distortions that enhance active site exposure and toluene desorption. The catalyst achieves a hydrogen evolution rate of 2625 mmol gPt⁻¹ min⁻¹ with 99.96% selectivity and excellent stability, offering a promising strategy for ...

An Ecosystem to Develop Multi‐Agent Systems in Real‐World IoT Applications

open access: yesSoftware: Practice and Experience, EarlyView.
ABSTRACT Software agents and multi‐agent systems are critical components in the development of distributed autonomous systems, as they exhibit a wide range of “intelligence,” from reactive behaviors to advanced reasoning and planning. Integrating these capabilities into multi‐agent systems enables distributed artificial intelligence, a programming ...

Evaluating model and simulation analyzing for P2P Churn

open access: yesTongxin xuebao, 2007
Most P2P algorithms based on distributed Hash table(DHT) faced Churn,which was caused by the continuous process of node joining and failure.A Churn evaluating model was proposed and its formulized description,which could give some important instructions ...

A Distributed Learned Hash Table

open access: yes2025 IEEE 33rd International Conference on Network Protocols (ICNP)
Distributed Hash Tables (DHTs) are pivotal in numerous high-impact key-value applications built on distributed networked systems, offering a decentralized architecture that avoids single points of failure and improves data availability. Despite their widespread utility, DHTs face substantial challenges in handling range queries, which are crucial for ...

Crux: Locality-Preserving Distributed Services

open access: yes, 2018
Distributed systems achieve scalability by distributing load across many machines, but wide-area deployments can introduce worst-case response latencies proportional to the network's diameter.

Quantifying Structural Complexity, Effort, and Performance: An Early Experiment Using Network Design Tasks

open access: yesSystems Engineering, EarlyView.
ABSTRACT Structural Complexity is perceived as driving cost in system development, yet managing it effectively requires empirical understanding. This study investigates human decision‐making using a toy transportation‐style network design task, focusing on how Structural Complexity, Effort, and Performance interact. Seventy‐four participants (primarily
