Multi-Static Reluctance Network With Constant Topology and Fixed Air Gap Parameters Applied to PMSG

IEEE Access
Multi-static reluctance networks (MRN) have been widely used to model the magnetic behavior of Permanent Magnet Synchronous Generators (PMSG), enabling the representation of the rotor motion. However, existing MRN approaches face limitations, as variable-

Turkey—The Return of the Reluctant Generals?

Political Science Quarterly, 1997
In 1996 and 1997, the international community has watched political events in Turkey with interest and some dismay. The unusual attention to Turkish affairs is largely because of the electoral prominence of Islam, which has raised questions about the overall stability of the secular state founded by Kemal Ataturk.

The Cost of a Nutritious Diet in Cafeterias: Evidence From US Military Dining Facilities

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Providing nutritious meals in institutional settings with financial constraints, such as military dining facilities, is challenging. The US Department of War (DoW) and US Department of Agriculture (USDA) collaborated to modernize the Basic Daily Food Allowance (BDFA) using an optimization model that incorporates service members' consumption ...

Drivers of Precision Agriculture Adoption in Italian Viticulture

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines the main drivers influencing the adoption of two types of precision farming technologies in the viticultural sector: Decision Support Systems (DSSs) and Variable Rate Technologies (VRTs). We apply a partial proportional odds model and find that socio‐demographic characteristics are not significant determinants of adoption ...

Swedish farmers' approval of nudges

Agribusiness, EarlyView.
Abstract Interest in the use of behavioral policy approaches, such as nudges, has strongly increased over the past years, including in the domains of food, agricultural and environmental policies. While the approval of nudges among the general public has been studied extensively, we know little about the attitude of farmers toward nudging. Farmers may (
