Wari Lithic Technology on the Northern Coast of the Andes: Geochemical, 2D Geometric Morphometric, and Technological Analyses of Obsidian Bifaces From San José de Moro

open access: yesArchaeometry, EarlyView.
ABSTRACT This study examines Wari obsidian production in a cache of 39 bifaces found at the Late Moche site of San José de Moro (Jequetepeque Valley, North Coast of Peru, 700–850 ad). Portable X‐ray fluorescence, geometric morphometric, and technological analyses were used to investigate raw material provenance and bifacial production.

Fused Collapsing for Wide BVH Construction

open access: yesComputer Graphics Forum, EarlyView.
Abstract We propose a novel approach for constructing wide bounding volume hierarchies on the GPU by integrating a simple bottom‐up collapsing procedure within an existing binary bottom‐up BVH builder. Our approach directly constructs a wide BVH without traversing a temporary binary BVH as done by previous approaches and achieves 1.4 – 1.6 × lower ...

A Novel Task Caching and Migration Strategy in Multi-Access Edge Computing Based on the Genetic Algorithm

open access: yesFuture Internet, 2019
Multi-access edge computing (MEC) brings high-bandwidth and low-latency access to applications distributed at the edge of the network. Data transmission and exchange become faster, and the overhead of the task migration between mobile devices and edge ...

Optimal Edge Caching for Individualized Demand Dynamics

open access: yesIEEE/ACM Transactions on Networking
The ever-growing end user data demands, and the simultaneous reductions in memory costs are fueling edge-caching deployments. Caching at the edge is substantially different from that at the core and needs to take into account the nature of individual data demands.

Image‐Based Spatio‐Temporal Interpolation for Split Rendering

open access: yesComputer Graphics Forum, EarlyView.
Abstract Low‐powered devices – such as small form factor head‐mounted displays (HMDs) – struggle to deliver a smooth and high‐quality viewing experience, due to their limited power and rendering capabilities. Cloud rendering attempts to solve the quality issue, but leads to prohibitive latency and bandwidth requirements, hindering use with HMDs over ...

Blockchain Based Decentralized and Proactive Caching Strategy in Mobile Edge Computing Environment

open access: yesSensors
In the mobile edge computing (MEC) environment, the edge caching can provide the timely data response service for the intelligent scenarios. However, due to the limited storage capacity of edge nodes and the malicious node behavior, the question of how ...

Encoding Occupancy in Memory Location for Efficient and Compact High‐Resolution Voxel Structures

open access: yesComputer Graphics Forum, EarlyView.
We encode information about geometric structure into the pointers of a sparse voxel directed acyclic graph (SVDAG). Each pointer carries information about the structure of the node it points to. Our encoding improves ray tracing performance and reduces model size in memory.

Extreme weather and economic crisis in the 1430s in England, and the implications for tenurial change

open access: yesThe Economic History Review, EarlyView.
Abstract The 1430s were characterized by extreme weather conditions, food and fodder shortages, and high mortalities among animals and humans, although the severity of events and their consequences in England have received limited attention. The economic downturn and the depressed customary land market in this decade marked the beginning of the Great ...

Dread in the Homeland: Symbolic Politics and Ethnonationalist Struggles for Self‐Determination in Nigeria

open access: yesNations and Nationalism, EarlyView.
ABSTRACT The revival of Biafran separatism in contemporary Nigeria is often explained with three leading theoretical frameworks: relative deprivation, political economy and state repression. Whereas relative deprivation and political economy perspectives posit that the resurgent separatism derives from the perception and empirical reality of ...

A Lightweight Caching Decision Strategy Based on Node Edge-Degree for Information Centric Networking

open access: yesIEEE Access
In-networkcaching as a core function in ICN can greatly improve the content distribution efficiency and reduce redundant network traffic. It is a challenge to design caching strategies in ICN to improve the performance of in-network caching.
