Internet-based computer information systems play critical roles in many aspects of the modern society. However, these systems are constantly under cyber attacks that can cause catastrophic consequences. In order to defend these systems effectively, it is necessary to measure and predict the effectiveness of cyber defense mechanisms. In this paper, we investigate how to measure and predict the e...

Water stress caused by water scarcity has a negative impact on the wine industry. Several strategies have been implemented for optimizing water application in vineyards. In this regard, midday stem water potential (SWP) and thermal infrared (TIR) imaging for crop water stress index (CWSI) have been used to assess plant water stress on a vine-by-vine basis without considering the spatial variabi...

Legumes of the genera Astragalus (milkvetch), Coronilla (crownvetch), Lathyrus (pea vine), Lotus (birdsfoot trefoil), Medicago (alfalfa), Melilotus (clover), Trifolium (clover), and Vicia (common vetch) were inoculated with a population of Melaidogyne chitwoodi from Utah or with one of three M. hapla populations from California, Utah, and Wyoming.Thirty-nine percent to 86% of alfalfa (M. scutel...

1 Outdoor trials were carried out during 2001–02 on strawberries grown in commercial growing bags naturally infested with black vine weevil larvae (BVW) Otiorhynchus sulcatus in Co. Wexford, Ireland. 2 The two nematode isolates used in these trials were Heterorhabditis megidis (UK211) and Heterorhabditis downesi (K122), both laboratory cultured. Growing bags received nematodes either once (May ...

A 2-year study was conducted to evaluate ecophysiological characteristics and yield±quality performance of cv. `̀ Aglianico'' (Vitis vinifera L.) grapevines trained to three different trellises at the same intrarow vine spacing and bud load per meter of row length. Bilateral guyot (BG) showed the lowest vine capacity and bilateral spur-pruned cordon (BSPC), with a vertical shoot positioning had ...

The objective of this study was to elevate water deficit tolerance by improving soluble sugar and free proline accumulation, photosynthetic pigment stabilization, photosynthetic abilities, growth performance and storage root yield in sweet potato cv. 'Tainung 57' using a foliar application of paclobutrazol (PBZ). The experiment followed a Completely Randomized Block Design with four concentrati...

This paper attempted to apply an EVT-based pairwise copula method for modelling risk interaction between foreign exchange rates and equity indices of the Johannesburg Stock Exchange (JSE) model dependence structure underlying assets with some selected listed stock indices. We filtered return residuals using stochastic volatility GJR-GARCH (1,1) models different distributions, we best-fitted in ...

Abstract Estimation of instantaneous peak discharge is important in the design hydraulic structures and reservoir management. In this study, a new approach called CEEMD-Copula-GARCH presented for simulating Qale Shahrokh basin, upstream Zayanderood Dam, Iran. developed method, Complementary ensemble empirical mode decomposition (CEEMD) algorithm was used to analyze observed values generate intr...
