Abstract:

Dehydrosqualene synthase enzyme has been used as protein target model for exploring docking simulation of pyrazoline analogues. One of diketopiperazine derivates that have similar structure to pyrazoline has antibacterial activity against Staphylococcus aureus (S. aureus). Vina is AutoDock- improved program that capable for molecular screening based on free-energy and binding conformation prediction between ligand and protein target. The aim of these studies is to screen diketopiperazine derivates on dehydrosqualene synthase of S. aureus using Vina. Diketopiperazine derivates, curcumin analogues, curcumin, pentagammavunon derivates (PGV-0 and PGV-1) were calculated for their geometry optimization energy using Gaussian-Density Functional Theory method. 3D-optimized ligands along with reference ligands were screened for their binding energy with dehydrosqualene synthase (2ZCO) by docking using Vina. The lowest values of binding energy were analyzed with statistic method. The results showed that top thirteen ligands of docking binding energy with receptor are diketopiperazine derivates (31%), curcumin analogues (31%), and reference ligands (38%). The new compounds of diketopiperazine derivates and curcumin analogues have better potency of binding energy than curcurmin as lead compound. Keywords: diketopiperazine, Vina, docking, Staphylococcus aureus, curcumin.

Abstract:

This study was conducted to evaluate the effects of sweet potato vine on the onset of puberty and the follicular development in the ovaries of Chinese Meishan gilts. A total of 20 Meishan gilts (initial body weight at 30 ± 0.18 kg) were randomly fed a control (CON) or sweet potato vine (SPV) supplemented diet until 19 days following the third estrous. Sweet potato vine was instead of part of basal diet with the same amount of energy and protein in the sweet potato vine group. The results indicate that gilts fed with sweet potato vine reached puberty 9.4 days later. The development of ovaries was enhanced by sweet potato vine supplementation, characterized by an increase (p < 0.05) in the relative weight of the ovaries and the number of large follicles (>5 mm). Sweet potato vine supplementation increased (p < 0.05) the total superoxide dismutase (T-SOD) and reduced (p < 0.05) the concentration of malondialdehyde (MDA) in the serum of the gilts. Also, the expression of superoxide dismutase-1 (SOD1) and luteinizing hormone receptor (LHR) mRNA in the granulosa cells from the large follicle (>5 mm) of gilts in the SPV group were increased (p < 0.05) as compared with the CON group. These results indicate that gilts fed with sweet potato vine exhibited delayed puberty as well as improved follicular development, which may contribute to the reproductive performance of Chinese Meishan gilts.

Abstract:

The use of residual biomass of forest and/or agricultural origin is an increasingly common issue regarding the incorporation of materials that, until recently, were out of the typical raw material supply chains for the production of biomass pellets, mainly due to the quality constraints that some of these materials present. The need to control the quality of biomass-derived fuels led to the development of standards, such as ENplus®, to define the permitted limits for a set of parameters, such as the ash or alkali metal content. In the present study, samples of vine pruning, and ENplus®-certified pellets were collected and characterized, and the results obtained were compared with the limits presented in the standard. The values presented from vine pruning approximated the values presented by Pinus pinaster wood, the main raw material used in the production of certified pellets in Portugal, except for the values of ash, copper (Cu), and nitrogen (N) contents, with vine pruning being out of the qualifying limits for certification. However, it was found that the incorporation of up to 10% of biomass from vine pruning allowed the fulfillment of the requirements presented in the ENplus® standard, indicating a path for the implementation of circular economy processes in the wine industry.

Abstract:

Combining corn with legumes for silage is a feasible strategy to improve crude protein concentration in corn silage. This study was conducted to determine the fermentation characteristics and overall nutritive value of ensiled corn (Zea mays L.), vine peas (Pisum sativum L.), and mixtures of the two crops at three different ratios. The two crops were ensiled in corn/pea mixtures containing 0, 33, 50, 67, and 100% corn in vacuumed plastic bags for 60 days at room temperature. The addition of peas to corn crude protein and dry matter concentrations in the ensiled forages had a negligible influence on neutral detergent fibre concentration compared with corn silage. Corn silage had a greater (P < 0.05) lactic acid concentration than vine peas silage and the mixtures. There were no differences (P > 0.05) in in vitro dry matter and neutral detergent fibre digestibility among the silages made from the vine peas, corn, and mixtures. Improved fermentation characteristics were obtained in vine peas and corn mixture silage at a ratio of 33 : 67 compared with the other mixtures and vine peas silage. Results generated from this study suggest that combining vine peas with corn for silage could provide livestock with not only a high energy concentration feed, but a high concentration of crude protein as well.

Abstract:

Of the grapevines grown in the Nordic countries, cv. Zilga, bred in Latvia, has proven to be very winter resistant and fast-maturing, and produces abundant harvests. In Finland, it is grown as horticultural and agricultural plant unprotected on open land even at 63 degrees latitude. In Southern Finland (60°24'10''N, 25°01'45''E), the growth cycle of cv. Zilga from bud break to harvest lasted 116 days and to leaf fall 125 days. At the beginning of the harvest, the total sugar content was 19°Bx. Tracking the phenology of the growth cycle and the environmental conditions of the growth site shows that cv. Zilga is well placed to make use of the high ambient temperatures and high solar radiation energy of Northern Europe in May, June, July and August.

Abstract:

In Europe, vine (Vitis vinifera L.) prunings are one of the most abundant types of agricultural waste. It is, therefore, essential to organize the removal of vine waste from the fields in order to prevent the spread of fires, pests, or diseases. Using plant biomass in buildings will help achieve greater energy efficiency and cause less environmental pollution. The objectives of this work were to minimize burning of agricultural waste, reduce the use of natural wood, and obtain a product by using vine pruning waste to manufacture particleboards, assessing their use as an insulating material and their fire-resistance qualities. Eight types of boards were manufactured with vine prunings (two particle sizes, two times, and two pressures), using 9% by weight of urea-formaldehyde as a bonding resin. Experimental tests were conducted to determine the physical, mechanical, thermal, and fire-resistance properties. In general, the panels manufactured performed well as a thermal insulating material with a conductivity between 0.0642 and 0.0676 W/m·K and a classification of Bd0 according to the European standards on fire resistance; some of them may be used to manufacture furniture, interior décor, and load-bearing panels in dry conditions.

Abstract:

Impedance spectroscopy measurements of the LiI-4AgI samples, in the frequency range 20 Hz{1 MHz, and in the temperature range between 353 K and 378 K were made. Both pure and lithium-doped silver iodide showed blocking phenomena in the electrodes and the grain boundary. The blocking phenomena allowed a change in the transport properties of the pure compound in respect to the doped compound as the temperature varied. The curves of electrical modulus in the LiI-4AgI system show asymmetric peaks corresponding with a weak correlation between mobile ions in the diusion process. The electrical conductivity in the AgI-LiI system can be described using a stretched relaxation function of the Kohlrausch-Williams-Watts (KWW) type. We speculat e that the phase of lithium dissolved in the silver iodide favors the formation of islands that disperses the conductivity due to the modication of the relationship among the microscopic energies: microscopic energy and migration energy.

Full text

Abstract:

The production of residual biomass, such as vine pruning, presents environmental problems since its elimination is usually carried out through the uncontrolled burning of the remaining materials and with the emission of greenhouse gases without any counterpart. The use of these residues to produce biochar presents several advantages. In addition to the more common energy recovery, other conversion ways allowing new uses, such as soil amendment and carbon sequestration, can be analyzed as options as well. In the present study, vine pruning biomasses are characterized to evaluate the behavior of the different constituents. Then, the different possible applications are discussed. It is concluded that materials resulting from the pruning of vineyards have excellent characteristics for energy recovery, with an increment of more than 50% in the heating value and almost 60% in the carbon content when carbonized. This recovery procedure contributes to creating new value chains for residual materials to promote sustainable practices in the wine sector.

Abstract:

Uncertainty about efficiency and sustainability of shrimp production due to diseases and climatic events may prevent Vietnam from attaining US $10 million target from shrimp exports by 2025. We surveyed 120 and 159 shrimp farmers from Khánh Hòa and Trà Vinh provinces, respectively, to obtain information on their input use, production levels and the effects of diseases and climate change events on their farm profitability. Stochastic production frontier analysis (SFA) discovered that the number of workers, crops and seed costs positively influenced farmers’ profits, while cost of chemicals and labour negatively affected the profit of Khánh Hòa farmers. The number of workers and chemical costs positively affected profits in Trà Vinh, while cost of labour and energy, the number of crops and average stocking density negatively influenced farmer profit in Trà Vinh. Number of years of schooling, experience and average size of ponds positively influenced economic efficiency, while the number of ponds and climatic change events negatively influenced efficiency in Khánh Hòa province. Age and alternative power source positively affected economic efficiency, while disease prevalence affected efficiency of Trà Vinh. All farms practicing intensive or extensive shrimp production achieved 90% efficiency. The government should encourage the wise use of resources, high-quality seeds and a sensitive balance between intensive and extensive culture to sustainably attain its national production and export goals.

Abstract:

AbstractThe purpose of this study was to investigate the hematological and inflammatory responses to 4 maximal high-intensity protocols, considering energy expenditure in each test. 9 healthy volunteers performed 4 high-intensity exercise tests of short [Wingate (WANT); Repeated-sprints (RSA)] and long durations [Continuous VO2 test (VCONT); intermittent VO2 test (VINT)] in a cycle-ergometer, until exhaustion. Hematological parameters and IL-6, IL-10 and creatine kinase (CK) levels were determined before (PRE), POST, 30 min, 1, 2, 12 and 24 h after the end of the protocols. Additionally, energy expenditure was determined. Leucocytes, erythrocytes and lymphocytes increased at POST and returned to PRE values at 30 min for all protocols. Lymphocytes had a second decreased at 2 h and granulocytes increased at 2 h when compared to PRE. Both variables returned to PRE values between 12–24 h into recovery. The magnitude of response for IL-6 was greater in VINT and for IL-10 in VCONT. There was no association of energy expenditure within each exercise protocol with the pattern of IL-6, IL-10 and CK responses to the exercise protocols. The present finding support that similar responses after continuous or intermittent acute protocols are observed when exercises are performed to volitional failure, regardless of the duration and mode of exercise.

Abstract:

Protein–ligand docking is a molecular modeling technique that is used to predict the conformation of a small molecular ligand at the binding pocket of a protein receptor. There are many protein–ligand docking tools, among which AutoDock Vina is the most popular open-source docking software. In recent years, there have been numerous attempts to optimize the search process in AutoDock Vina by means of heuristic optimization methods, such as genetic and particle swarm optimization algorithms. This study, for the first time, explores the use of cuckoo search (CS) to solve the protein–ligand docking problem. The result of this study is CuckooVina, an enhanced conformational search algorithm that hybridizes cuckoo search with differential evolution (DE). Extensive tests using two benchmark datasets, PDBbind 2012 and Astex Diverse set, show that CuckooVina improves the docking performances in terms of RMSD, binding affinity, and success rate compared to Vina though it requires about 9–15% more time to complete a run than Vina. CuckooVina predicts more accurate docking poses with higher binding affinities than PSOVina with similar success rates. CuckooVina’s slower convergence but higher accuracy suggest that it is better able to escape from local energy minima and improves the problem of premature convergence. As a summary, our results assure that the hybrid CS–DE process to continuously generate diverse solutions is a good strategy to maintain the proper balance between global and local exploitation required for the ligand conformational search.

Abstract:

Photovoltaic (PV) technology is one of the important renewable energy resources as it is pollution free and clean. PV systems have a high cost of energy and low eciency, consequently, they not made it fully attractive as an alternative option for electricity users. It is essential that PV systems are operated to extract the maximum possible power at all times. Maximum Power Point (MPP) changes with atmospheric conditions (radiation and temperature), it is dicult to sustain MPP at all atmospheric levels. Many Maximum Power Point Tracking (MPPT) have been developed and implemented. These methods varied according to several aspects such as a number of sensors used, complexity, accuracy, speed, ease of hardware implementation, cost and tracking eciency. The MPPT techniques presented in the literature indicate that Variable step size of Perturb & Observe (VP&O), Variable step size of Incremental Conductance (VINC) and Perturb & Observe (P&O) using Fuzzy Logic Controller (FLC) can achieve reliable global MPPT with low cost and complexity and be easily adapted to dierent PV systems. In this paper, we established theoretical and experimental verication of the main MPPT controllers (VP&O, VINC, and P&O using FLC MPPT algorithms) that most cited in the literature. The three MPPT controller has been tested by MATLAB/Simulink to analyze each technique under dierent atmospheric conditions. The experimental results show that the performance of VINC and P&O using FLC is better than VP&O in term of response time.

Abstract:

This paper primarily aims at giving an introduction to an alternative opportunity for vineyards owners many of whom have come to adecision about elimination of their vineyards. The paper is focusing on the Mátra wine-region as a study area, which is the largest mountainwine region in Hungary where more than one third of supported clearing of vineyards have been implemented in the last few years. Theabandoning of vineyards is explicable in more than one way such as very small average size of land or the increasing mean age of ownersetc. The fundamental reason is the chronic doubtfulness of the grape and wine market and the low level of overall profitability of production.Grape production has a long tradition in this region, thus the disappearance of vineyards caused serious problems in land use through theabsolute lack of plans for the future. The popularity of biomass production in the press and the biofuel resultant from vine stocks raiseinterest for short rotation forestry within a group of farmers. Short rotation forestry offers a new chance for some farmers to cut oneself adriftfrom the harmful effects of the market of agricultural products.

Abstract:

For more than ten years, pulsed electric field (PEF) technology has been the subject of a growing number of publications and patents. The technology previously reserved for laboratories is becoming more and more popular and is now a success in the food industry. Since 2015, with the help of the Occitania region, we have been studying the use of the PEF on the microbiological stability of wines on a semi-industrial scale from 5 to 12 hl/hour. This low thermal and energy consuming physical technology requires no inputs to ensure the destruction of microorganisms and microbial stabilization of wines. These tests are performed with a 7 kV/cm electric field generated between the 2 electrodes of the treatment chambers. The objective is to ensure the microbial stabilisation of wines not exceeding 50 ∘C and to cool the wine immediately after treatment without maintaining it at high temperature. The study of the effectiveness of PEF on yeast destruction is carried out during the mutage of sweet wines. The first results obtained show a very good efficiency of the yeast treatment with an instant cessation of alcoholic fermentation and a decrease in the yeast population ranging from − 3 to − 5 Log. No SO2 addition is then required. On wines contaminated by Brettanomyces, the tests show an almost total elimination (< 1/100 ml) of these yeasts by the PEF treatment. These tests also showed that a higher energy level is required to eliminate all lactic acid bacteria from wine. No effects on the physico-chemical characteristics of the wines were found. The impact on the organoleptic characteristics of wines is ongoing. An optimization of the electrical parameters is still necessary.

Abstract:

Based on the canonical vine (C-vine) copula approach, this paper examines the interdependence between the exchange rates of the Chinese Yuan (CNY) and the currencies of major Association of Southeast Asian Nations (ASEAN) countries. The differences in the dependence structure and degree between currencies before and after the Belt and Road (B&R) Initiative were compared in order to investigate the changing role of the Renminbi (RMB) in the ASEAN foreign exchange markets. The results indicate a positive dependence between the exchange rate returns of CNY and the currencies of ASEAN countries and show the rising power of RMB in the regional currency markets after the B&R Initiative was launched. Besides this, the Malaysian Ringgit proved to be most relevant to the other ASEAN currencies, thus playing an important role in the stability of regional financial markets. Moreover, evidence of tail dependence was found in the returns of three currency pairs after the B&R Initiative, which implies the presence of asymmetric dependence between exchange rates. The results from time-varying C-vine copulas further confirmed the robustness of the results from the static C-vine copulas.

Abstract:

This paper concentrates on the capacity credit (CC) evaluation of wind energy, where a new method for constructing the joint distribution of wind speed and load is proposed. The method is based on the skew-normal mixture model (SNMM) and D-vine copulas, which is used to model the marginal distribution and the correlation structure, respectively. Then a cross entropy based importance sampling (CE-IS) is improved to enhance the efficiency of the power system reliability assessment, which is a crucial part of the CC evaluation. After that, the proposed methods are adopted to combine with the secant method to develop a complete algorithm to calculate the CC of wind energy. Numerical tests are designed and carried out based on the IEEE-RTS 79 system and wind speed data obtained from four wind farms in Northwest China. In order to show the superiority of SNMM and D-vine copula, the goodness-of-fit is quantified by different statistics. Besides, the improved CE-IS method is validated by comparison with Monte Carlo sampling (MCS) and traditional CE-IS in the efficiency of reliability assessment. Finally, the proved methods are combined with the secant method to calculate the CC of four wind farms, which can provide information for wind farm planning.

Abstract:

The contribution describe the possibilities of using marc for manufacturing pellets for energy purposes. Experiments associated with pellet production were performed in several variants. Biomass pellet variants consisted of different percentages of vine shoots from vineyards, as well as marc and hay. These test variants were measured for their calorific value, which ranged between 17.36 and 19.21 MJ.kg−1. Bulk density was also determined, ranging between 619.27 and 630.9 kg.m−3. Pellets produced with marc content were also tested for mechanical durability, which was between 96.15 and 96.82% for the test variants. The calorific value, alongside other parameters assessed, shows favourable characteristics towards use in combustion processes. The results obtained show that in terms of the parameters analysed, marc pellets could be an attractive commodity for combustion.

Abstract:

Guaraná (Paullinia cupanaH.B.K., Sapindaceae) is a rainforest vine that was domesticated in the Amazon for its caffeine-rich fruits. Guaraná has long been used as a tonic and to treat various disorders in Brazil and abroad and became a national soda in Brazil about a century ago. In the last two decades or so, guaraná has emerged as a key ingredient in various ‘sports’ and energy drinks as well as concoctions that allegedly boost one's libido. For some time, guaraná's high caffeine content was thought to be a detriment because of health concerns about excessive intake of caffeine-rich drinks. But it is precisely this quality, and the fact that it has a mysterious name and comes from an exotic land, that has propelled guaraná into a global beverage.

Abstract:

Agrarian pruning and plantation removal (APPR) is a common residue from pomo-technical maintenance of orchards, vineyards, and olive groves, frequently overlooked by the energy sector. This paper sheds new light on the socio-economic role of APPR as solid biofuel. The paper suggests business models that could both alleviate energy poverty in rural areas and increase the competitiveness of perennial crop (fruits, olives, vine) production. The effects of mobilizing APPR potential via business models are estimated at the micro (households’ income) and macro (number of households affected, size of the investment, tax effect, CO2eq savings) levels in the Croatian setting. Contrary to classical energy planning, the paper provides an approach that fosters local use of bioenergy by linking rural development with renewable energy end-use. The approach linked pruning energy potential with 47% of Croatian rural households which allows creating an evidence-based policy for rural development utilizing APPR as a sustainable solid biofuel. The most attractive business model for Croatian rural areas is utilization of APPR as a solid biofuel. It could be used as an energy poverty alleviation measure, allowing savings per heating season equivalent to 5%–11% of the average disposable income per household. Net APPR influence at VAT tax is estimated at 5.5 million euro·y−1. The paper proves that using average values for APPR in energy planning could be misleading.

In addition, the resistance of sensors response to oxygen partial pressure was discussed by Kroger–Vink model. The response properties indicated that Pt modified TiO2 was providing excellent response properties when the sensor exposed to hydrogen and oxygen. The response mechanism was suggested to arise from the activation energy (E) of the modified sensing films.

Abstract:

This study explored the impact of fresh sweet potato vine on the growth as well as the metabolites and colon microbial composition in Chinese Meishan gilt. Twenty Meishan gilts (body weight 30 ± 0.18 kg, n = 10 per treatment) were randomly assigned to a control (CON) or sweet potato vine (SPV) supplementation diet treatment. Gilts were housed in individual stalls. In the SPV treatment, 2 kg fresh sweet potato vine was used instead of 0.18 kg basal diet which provided the same amount of digestive energy and crude protein with the exception of crude fiber (CON, 51.00 g/d vs. SPV, 73.94 g/d) in terms of dry matter intake. Gilts were slaughtered and samples were collected on day 19 after the third estrus cycle. The SPV treatment tended to increase slaughter weight of gilts (p = 0.07); it also increased (p < 0.05) gastrointestinal tract weight and intestinal muscle layer thickness. SPV treatment also decreased (p < 0.05) carcass yield and subcutaneous adipose tissue. The concentration of zonulin and endotoxin in plasma was decreased (p < 0.05) as the gilt consumed the SPV diet. Colonic fecal concentrations of endotoxin, lipocalin-2, and tumor necrosis factor-α (TNF-α) were decreased (p < 0.05), and interleukin-10 (IL-10) was increased (p < 0.05) in the SPV treatment. Butyric acid and acetate concentration in colonic content as well as acetate concentration in caecal content were increased (p < 0.05) in the SPV treatment. Furthermore, the expression of carnitine palmityl transferase (CPT-1) and peroxisome proliferator-activated receptor-α (PPAR-α) in gilt liver in SPV treatment was increased (p < 0.05) in comparison with CON treatment. Meanwhile, the composition of the colon microbes was also altered by SPV; representative changes included an increase in Lactobacillus, Bacteroides, Roseburia, and Lachnospira. These results indicate that gilt fed with sweet potato vine had decreased gut permeability, endotoxin and pro-inflammatory cytokines concentrations; colonic fecal microbiota was also changed, which may be further beneficial to the intestinal health of Chinese Meishan gilt.

Abstract:

This paper investigates the dynamic tail dependence risk between BRICS economies and the world energy market, in the context of the COVID-19 financial crisis of 2020, in order to determine optimal investment decisions based on risk metrics. For this purpose, we employ a combination of novel statistical techniques, including Vector Autoregressive (VAR), Markov-switching GJR-GARCH, and vine copula methods. Using a data set consisting of daily stock and world crude oil prices, we find evidence of a structure break in the volatility process, consisting of high and low persistence volatility processes, with a high persistence in the probabilities of transition between lower and higher volatility regimes, as well as the presence of leverage effects. Furthermore, our results based on the C-vine copula confirm the existence of two types of tail dependence: symmetric tail dependence between South Africa and China, South Africa and Russia, and South Africa and India, and asymmetric lower tail dependence between South Africa and Brazil, and South Africa and crude oil. For the purpose of diversification in these markets, we formulate an asset allocation problem using raw returns, MS GARCH returns, and C-vine and R-vine copula-based returns, and optimize it using a Particle Swarm optimization algorithm with a rebalancing strategy. The results demonstrate an inverse relationship between the risk contribution and asset allocation of South Africa and the crude oil market, supporting the existence of a lower tail dependence between them. This suggests that, when South African stocks are in distress, investors tend to shift their holdings in the oil market. Similar results are found between Russia and crude oil, as well as Brazil and crude oil. In the symmetric tail, South African asset allocation is found to have a well-diversified relationship with that of China, Russia, and India, suggesting that these three markets might be good investment destinations when things are not good in South Africa, and vice versa.

Abstract:

Motivation: Bringing a new drug to the market is expensive and time-consuming. To cut the costs and time, computer-aided drug design (CADD) approaches have been increasingly included in the drug discovery pipeline. However, despite traditional docking tools show a good conformational space sampling ability, they are still unable to produce accurate binding affinity predictions. This work presents a novel scoring function for molecular docking seamlessly integrated into DockingApp, a user-friendly graphical interface for AutoDock Vina. The proposed function is based on a random forest model and a selection of specific features to overcome the existing limits of Vina’s original scoring mechanism. A novel version of DockingApp, named DockingApp RF, has been developed to host the proposed scoring function and to automatize the rescoring procedure of the output of AutoDock Vina, even to nonexpert users. Results: By coupling intermolecular interaction, solvent accessible surface area features and Vina’s energy terms, DockingApp RF’s new scoring function is able to improve the binding affinity prediction of AutoDock Vina. Furthermore, comparison tests carried out on the CASF-2013 and CASF-2016 datasets demonstrate that DockingApp RF’s performance is comparable to other state-of-the-art machine-learning- and deep-learning-based scoring functions. The new scoring function thus represents a significant advancement in terms of the reliability and effectiveness of docking compared to AutoDock Vina’s scoring function. At the same time, the characteristics that made DockingApp appealing to a wide range of users are retained in this new version and have been complemented with additional features.

Abstract:

AbstractTo achieve ambitious climate goals, it is necessary to increase the rate of purposeful retrofit measures in the building sector. As a result, Energy Performance Certificates have been designed as important evaluation and rating criterion to increase the retrofit rate in the EU and Germany. Yet, today’s most frequently used and legally required methods to quantify building energy performance show low prediction accuracy, as recent research reveals. To enhance prediction accuracy, the research community introduced data-driven methods which obtained promising results. However, there are no insights in how far Energy Quantification Methods are particularly suited for energy performance prediction. In this research article the data-driven methods Artificial Neural Network, D-vine copula quantile regression, Extreme Gradient Boosting, Random Forest, and Support Vector Regression are compared with and validated by real-world Energy Performance Certificates of German residential buildings issued by qualified auditors using the engineering method required by law. The results, tested for robustness and systematic bias, show that all data-driven methods exceed the engineering method by almost 50% in terms of prediction accuracy. In contrast to existing literature favoring Artificial Neural Networks and Support Vector Regression, all tested methods show similar prediction accuracy with marginal advantages for Extreme Gradient Boosting and Support Vector Regression in terms of prediction accuracy. Given the higher prediction accuracy of data-driven methods, it seems appropriate to revise the current legislation prescribing engineering methods. In addition, data-driven methods could support different organizations, e.g., asset management, in decision-making in order to reduce financial risk and to cut expenses.

Abstract:

Late frosts are one of the major impact factors on agriculture worldwide with large economic losses for agricultural crops, with a significant impact also in wine production. Given the importance of the wine sector in the world, more and more efforts are being made to identify innovative techniques capable of creating a low-cost and effective protection for vine shoots, as well as reducing energy consumption. In a previous work, cotton candy was identified as an insulating material to solve the problems related to late frosts on vineyards and limit its damages as much as possible. From the results of the previous research, it has proved that cotton candy is an excellent thermal insulator, but it degrades quickly in windy conditions. Thus, climatic tests carried out in windy condition showed that straw can greatly slow down the degradation of cotton candy over time, giving an indirect contribution to the protective effectiveness of cotton candy. In addition, several tests were conducted with different amounts of sugar and straw without wind to evaluate whether the straw can itself make a contribution in terms of thermal insulation, as well as contribute to the protective effectiveness of cotton candy, minimizing energy use as well.
