Grape Quality Zoning and Selective Harvesting in Small Vineyards—To Adopt or Not to Adopt

نویسندگان

چکیده

The practical application of grape quality zoning and selective harvesting in small vineyards (<1 ha) has not yet gained much importance worldwide. However, winegrowers with are looking for ways to improve wine maximise profit. Therefore, the aim this study was identify most predictive vegetation index among three indices—NDVI, NDRE, OSAVI—at grapevine growth stages efficient use production different types from same vineyard. Multispectral images were used delineate two vigour zones at stages. target vines sampled, determined by overlapping structures each site year. A differential economic analysis performed, considering only costs revenues associated zoning. results show that OSAVI is least predictive, while NDVI NDRE useful harvesting. Multi-year monitoring required determine ideal stage image acquisition. can be economically wineries producing “super-premium” wines

To Adopt or Not to Adopt - That is the Question

The area of adoption and diffusion has had a strong pro-innovation bias (Brancheau and Wetherbe 1990; Parthasarathy and Bhattacherjee 1998; Ram 1987; Venkatesh and Brown 2001). This bias has resulted in somewhat of a neglect of the area of non-adoption. Existing theories including TAM (Davis 1989) and the innovation diffusion theory (Rogers 1983) provide critical insights into technology usage....

Generalizing ADOPT and BnB-ADOPT

ADOPT and BnB-ADOPT are two optimal DCOP search algorithms that are similar except for their search strategies: the former uses best-first search and the latter uses depth-first branch-and-bound search. In this paper, we present a new algorithm, called ADOPT(k), that generalizes them. Its behavior depends on the k parameter. It behaves like ADOPT when k = 1, like BnB-ADOPT when k = ∞ and like a...

Small Enterprises' Predisposition to Adopt an ERP

Enterprise resource planning systems (ERPs) are now being implemented in small and medium enterprises (SMEs). In addition to allowing for the integration of technological architectures, these systems make best practices available to small firms. This paper presents the results of a study that was aimed at identifying the dimensions of SMEs’ readiness for the adoption of this new technology.

ADOPT: Asynchronous Distributed Constraint Optimization with Quality Guarantees ADOPT: Asynchronous Distributed Constraint Optimization with Quality Guarantees

The Distributed Constraint Optimization Problem (DCOP) is able to model a wide variety of distributed reasoning tasks that arise in multiagent systems. Unfortunately, existing methods for DCOP are not able to provide theoretical guarantees on global solution quality while allowing agents to operate asynchronously. We show how this failure can be remedied by allowing agents to make local decisio...
