Yield prediction models

The classification results show that features selected using sepsis subpopulations as background knowledge yield a superior performance in distinguishing septic from non-septic patients regardless of the classification model used. The improved performance is especially pronounced in specificity, which is a current bottleneck in sepsis prediction machine learning models.

After the deep drawing of cup-shaped features, the product develops a "earing" due to the anisotropy of the sheet metal. Predicting the formation of "earing" during the deep drawing process is crucial for decreasing this fault. The goal of this work is to forecast the production of "earing" during the deep drawing process of a cup-shaped detail made of stainless steel SUS304 by modeling and experimental results.

Usnic acid (UA) was extracted from Usnea longissima (L.) Ach. in supercritical carbon dioxide (SC-CO2 ) medium. The selected process parameters were extraction temperature (35–45 °C), amount of co-solvent (0%–5%) and extraction time (5–9 h). These parameters were applied to Box-Behnken design (BBD) belonging to response surface methodology (RSM) to determine optimum process parameters for the highest amount of UA in the extract. g UA/100g lichen, extraction yield % and UA content values were calculated in the range of 0.045–0.317, 2.77–5.

A Kunitz-type trypsin inhibitor protein has been purified and characterized from seeds of Acacia nilotica L. LC-MS/MS analysis of Acacia nilotica trypsin inhibitor (AnTI) provided the N-terminal fragment of 11 amino acids which yielded 100% identity with already reported Kunitz-type trypsin inhibitor protein of Acacia confusa (AcTI) in UniProtKB database search.

This study compares the price predictions of the Vanguard real estate exchangetraded fund (ETF) (VNQ) using the back propagation neural network (BPNN) and autoregressive integrated moving average (ARIMA) models. The input variables for BPNN include the past 3-day closing prices, daily trading volume, MA5, MA20, the S&P 500 index, the United States (US) dollar index, volatility index, 5-year treasury yields, and 10-year treasury yields. In addition, variable reduction is based on multiple linear regression (MLR).

Forecasting solar irradiance has been an important topic and a trend in renewable energy supply share. Exact irradiance forecasting could help facilitate the solar power output prediction. Forecasting improves the planning and operation of the Photovoltaic (PV) system and the power system, then yields many economic advantages. The irradiance can be forecasted using many methods with their accuracies.

Predictive models for the rice crop (Oryza sativa L.) of Chhattisgarh plain and its constituent districts have been made. Models have been fitted for the area, productivity and production of the crop separately for above region. Based on these models prediction of area productivity and production of rice have been made year wise between 1998-99 to 2013-14.

The explosive growth of microbiome research has yielded great quantities of data. These data provide us with many answers, but raise just as many questions. 16S rDNA—the backbone of microbiome analyses—allows us to assess α-diversity, β-diversity, and microbe-microbe associations, which characterize the overall properties of an ecosystem.

Regression models by Hendrick and Scholl technique were developed on sorghum for Tapi and Surat districts of South Gujarat. The daily weather data were used in the study as indicator in crop yield prediction were collected for a period of 32 years. The 28 year data was used for development of the model. The validation of model was done using data set of 2010, 2011, 2012 and 2013.

The weather variables affect the crop differently during various stages of development (Tripathi et al., 2012). Thus, extent of weather influence on crop yield depends not only on the magnitude but also on the distribution pattern of weather variables over the crop season.

The major threat of the agricultural crop is the climate change, which grown globally in the subtropical and the tropical regions. Negative impact on the plant growth, development and the economic yield regarding climate change due to consequences of the draught stress. For the prediction of the climate change and occurrence of the draught many simulation models were recorded, it’s very necessary to improve the crop against the draught stress which ultimately limits the production and the productivity of the crop.

The aim of this study was the calibration and validation of DSSAT model (v4.5) for late sown wheat in western zone of Haryana. The DSSAT model was calibrated with the field experimental data of rabi 2010-11 having 3 levels of irrigation (one irrigation at crown root initiation [CRI], two irrigations at CRI and heading and four irrigations at CRI, late tillering, heading and milking) and 5 nitrogen levels (0, 50, 100, 150 and 200 kg N/ha) and validated with data of experiment rabi 2011-12 conducted at Hisar (29°10ˈ N and 75°46ˈ E).

A set of 27 pearl millet (Pennisetum glaucum (L.) R. Br.] ) hybrids that newly developed using A1 cytoplasmic male-sterile lines, were evaluated over three (two wet and one dry) crop seasons (hereafter refer to as environments) in Randomized Complete Block Design (RCBD) with two replications to predict genotype by environment (G × E) interaction for grain yield and its component traits, and to identify the high yielding stable hybrids through AMMI and cluster analysis method for possible adaption. Analysis of variance showed significant genetic variation for all studied traits exists.

Parameter estimation in statistical modelling plays a crucial role in the real world phenomena. Several alternative analyses may be required for the purpose. An attempt has been made in this paper to estimate the yield of wheat crop using principal components of the weather parameters spread over the crop growth period. Principal component analysis has been used for the purpose of developing zonal yield forecast models because of multicollinearity present among weather variables.

Crop yield models are abstract presentation of interaction of the crop with its environment and can range from simple correlation of yield with a finite number of variables to the complex statistical models with predictive end. The pre-harvest forecasts are useful to farmers to decide in advance their future prospects and course of action. ARIMAX models have been fitted for cotton yield forecasting in Hisar, Fatehabad and Sirsa districts of Haryana.
