Ambiguity-Resolved Model Tests for Carrier-Phase GNSS

Applied Sciences
Although the theory of mixed-integer inference is well developed for GNSS parameter estimation, such is not yet the case for the validation and monitoring of mixed-integer GNSS carrier-phase models.

Amidst (waste) abundance: world‐making and struggles in hosting a municipal landfill in the Bolivian lowlands Au milieu de l'abondance (de déchets) : fabrication du monde et luttes liées à la gestion d'une décharge municipale dans les basses terres de Bolivie

Journal of the Royal Anthropological Institute, EarlyView.
In recent decades, solid waste has proliferated worldwide, becoming a pressing global issue. This article explores the role of Indigenous people dwelling within and upon emerging waste scenarios, with a specific focus on involved forms of sociality and ontological contestation. Drawing on the case of a municipal landfill sited on a Guarani community in

Extended GNSS ambiguity resolution models with regularization criterion and constraints

, 2009
This paper firstly presents an extended ambiguity resolution model that deals with an ill-posed problem and constraints among the estimated parameters. In the extended model, the regularization criterion is used instead of the traditional least squares ...

A novel stop-and-go kinematic positioning method for PPP–RTK

Geo-spatial Information Science
The technology of precise point positioning – real time kinematic (PPP – RTK) can realize regional accurate positioning. However, poor quality atmospheric corrections can greatly impact the integer ambiguity resolution.

Not all Temperature Shocks are Alike: Disentangling Heat and High Temperature Shocks and Their Effects on Inflation in Australia

Economic Record, EarlyView.
We study the effects of heat and high temperature shocks on inflation in Australia using monthly, state‐level temperature anomaly data via two stages. In the first stage, we decompose temperature anomalies into orthogonal components using a structural vector autoregression with long‐run restrictions.

Intra‐Seasonal Crop Management and the Potential Benefit of Seasonal Precipitation Forecasts: Farm‐Level Embedded Risk Analysis in Ethiopia

Journal of Agricultural Economics, EarlyView.
ABSTRACT How large is the potential benefit for farmers from obtaining forecasts of total rainfall in the upcoming season? This critically depends on the local farm system and the crop management actions available to farmers to respond to the forecasts issued. Studies assessing the financial value of seasonal precipitation forecasts have so far focused

Seek and Ye Might Not Find: The Effects of Contract Framing on Knowledge Sharing and Knowledge Seeking Qui cherche ne trouve pas toujours : les effets liés à la formulation des contrats sur le partage et la recherche de renseignements

Contemporary Accounting Research, EarlyView.
ABSTRACT We conduct two experiments to examine whether and how the framing (bonus vs. penalty) of a target‐based incentive contract affects knowledge sharing and knowledge seeking. In the first experiment, we predict and find that penalty‐framed contracts increase employees' stress due to the fear of potential loss, which in turn reduces their ...

When Accounting Qualities Collide: Accruals Quality, Comparability and Information Risk in SEO Underpricing

Accounting &Finance, EarlyView.
ABSTRACT We examine how accounting quality attributes jointly mitigate underpricing associated with two dimensions of information risk in seasoned equity offerings (SEOs). In information environments with relatively more potent information asymmetry, the evidence suggests that accruals quality and accounting comparability act as substitutes; i.e ...

A Simple Sequential Method for Integer Ambiguity Resolution in Real-Time GNSS Positioning

, 2008
The successful resolution of integer ambiguities in Global Navigation Satellite System (GNSS) carrier-phase measurements is an essential but challenging task, especially where real-time kinematic (RTK) positioning is concerned.

Volume Quantization with Flexible Singularities for Hexahedral Meshing

Computer Graphics Forum, EarlyView.
Abstract We present a novel algorithm for quantization and subsequent hexahedral mesh generation from seamless volumetric maps. Quantization is the process of choosing integers that represent the numbers of hexahedral elements to be placed in each region of the volume, and transforming the seamless map into an integer‐grid map matching that choice ...
