Abstract:

During the years of study (2015–2017) there were considered and studied parameters of adaptability of winter soft wheat varieties sown after maize. As a result, the productivity of winter wheat ranged from 77.6 hwt/ha (the variety ‘Polina’) to 83.9 hwt/ha (the variety ‘Kaprizulya’). At a most the productivity varied through the years from 52.5 hwt/ha (the variety ‘Kapitan’) in 2016 to 108.2 hwt/ha (the variety ‘Kaprizulya’) in 2017. The main feature of breeding on adaptability is to control ecological plasticity and stability of the varieties in the breeding process. The varieties ‘Krasa Dona’ and ‘Kaprizulya’ having 1.0 regressive coefficient are considered to be ecologically adaptable. The varieties ‘Lidiya’, ‘Kapitan’, ‘Lilit’ and ‘Volnitsa’ having > 1.0 regressive coefficient are considered to be highly responsive. The varieties ‘Lilit’ and ‘Volny Don’ are characterized with stable genotype (σd2 tends to zero). The varieties ‘Polina’ and ‘Volny Don’ belong to the group of varieties with high indexes of homeostatism, breeding value and low coefficients of variations. The varieties ‘Polina’ and ‘Volny Don’ demonstrate high indexes of stress resistance with the lowest negative values of differences among minimum and maximum indexes of the trait. The varieties ‘Kaprizulya’, ‘Lilit’, ‘Krasa Dona’ and ‘Volny Don’ are found genetically flexible genotypes, as they possess high correspondence degree between the genotype and the environment. According to the parameters of adaptability there have been identified the varieties ‘Polina’ and ‘Volny Don’ with stability, breeding value, stress resistance and high productivity.

Abstract:

The antioxidant activity, lipid peroxidation, and contents of free proline and soluble proteins were investigated on six-year-old beech plants. Provenance Avala, in Serbia, had the best adaptability to environmental factors on locality Fruska Gora due to low lipid peroxidation, high FRAP value, and free proline and soluble proteins contents. Provenances Scharnstein and Mitterndorf, in Austria, had the best adaptability to environmental factors on locality Debeli Lug due to high FRAP value and free proline and soluble proteins contents. FRAP values in majority of provenances from locality Debeli Lug were higher. Correlations parameters were much higher between provenances in locality Debeli Lug, situated at higher altitude, which is the consequence of better adaption to environmental factors influence.

Abstract:

ABSTRACT The objective of this study was to identify the plant arrangement that allows greater grain yield with adaptability and stability of rapeseed hybrids. The experiments were conducted in randomized block design with four replicates and the 12 treatments consisted of combination of inter-row spacings (0.20, 0.40, and 0.60 m) and plant densities (20, 40, 60 and 80 plants m-2). The hybrids Hyola 432 (early cycle) and Hyola 61 (medium cycle) were cultivated in three growing seasons (2008, 2009 and 2010). Grain yield was evaluated based on the parameters adaptability and stability according to the models of Wricke and Eberhart & Russell. The plant arrangement for obtaining higher grain yield depends on the cultivated genotype. Higher grain yield was obtained in the arrangements of 0.20 m x 60 and 0.40 m x 60 plants m-2 for Hyola 432, and in 0.20 m x 60 plants m-2 for Hyola 61, in the three years of evaluation. In the inter-row spacing of 0.40 m and densities of 40 and 60 plants m-2, Hyola 432 shows high yield, adaptability to wide environments and stability. For Hyola 61, high productivity with overall adaptability was obtained in the inter-row spacing of 0.40 m, with 60 plants m-2.

Abstract:

The ability of macromolecules to transduce stimulus information at one site into conformational changes at a distant site, termed “allostery,” is vital for cellular signaling. Here, we propose a link between the sensitivity of allosteric macromolecules to their underlying biophysical parameters, the interrelationships between these parameters, and macromolecular adaptability. We demonstrate that the parameters of a canonical model of the mSlo large-conductance Ca2+-activated K+ (BK) ion channel are non-identifiable with respect to the equilibrium open probability-voltage relationship, a common functional assay. We construct a reduced model with emergent parameters that are identifiable and expressed as combinations of the original mechanistic parameters. These emergent parameters indicate which coordinated changes in mechanistic parameters can leave assay output unchanged. We predict that these coordinated changes are used by allosteric macromolecules to adapt, and we demonstrate how this prediction can be tested experimentally. We show that these predicted parameter compensations are used in the first reported allosteric phenomena: the Bohr effect, by which hemoglobin adapts to varying pH.

Abstract:

The estimation of the initial material is the most important part of the breeding process. There is a great necessity in additional objectivity of its characteristics, in identification of the parameters of environmental adaptability, stability, resistance to stressful environmental conditions. Within the collection nursery there have been studied adaptability parameters of 16 sainfoin samples (Onobrychis arenaria Kit. DC) of a sandy species. The purpose of research was to identify sainfoin forms with a complex of adaptive traits based on such characteristics as “green mass productivity” and “seed productivity” to use them in future breeding work. There have been used conventional techniques in the study. The estimation of the adaptability parameters was carried out according to Eberhart S.G., Russell W.G. (1966) presented by V.A. Zykina et al. (2005) and by V.Z. Pakudin (1984). The conducted dispersion analysis of the two-factor trial on the productivity of sainfoin samples showed the correlation between the genotype and the environment. The change in green mass and seed productivity was greatly influenced by the factor ‘year’ (‘environment’) (51% and 58%, respectively). The influence of the factor ‘variety’ (‘sample’) was less (40.7% and 35.5%), the correlation of these factors was also reliable, the interaction variance exceeded the error value and was 65% and 79%. The estimation of sainfoin samples for the presence of adaptive properties revealed that almost all the studied samples had at least one adaptive parameter. But, the sainfoin samples that have several or a set of calculated adaptive properties are obviously more valuable for the use in the breeding process. When cultivating for green mass and seeds, the samples ‘S 5/05’ and ‘GIA 4’ had a high level of resistance to stressful growing conditions (Umin-Umax), a high level of environmental adaptability (bi) and stability (Si2 ), and the samples ‘GIA 2’ and ‘GIA 11’ have these parameters only if they are cultivated for green mass. The variety ‘Severokavkazsky Dvuukosny’ is characterized with high resistance to stressful growing conditions (Umin-Umax) and genetic flexibility ((Umin + Umax) / 2), with a high level of ecological adaptability (bi) and homeostatism (HOM).

Abstract:

When the animals exposed to the high environmental temperature most of the physiological and biochemical parameters are disturbances. The heat-induced changes in each of thermoregulatory parameters as well as water, protein turnover or balances and hormonal levels may be used for evaluation the animal's adaptability to hot climate. Detection of such phenomena in the animals could be achieved by different indices. Most of indices which may be used for detecting the heat adaptability in animals are reviewed in this article paper.

Abstract:

The objective of this work was to estimate the repeatability of adaptability and stability parameters of common bean between years, within each biennium from 2003 to 2012, in Minas Gerais state, Brazil. Grain yield data from trials of value for cultivation and use common bean were analyzed. Grain yield, ecovalence, regression coefficient, and coefficient of determination were estimated considering location and sowing season per year, within each biennium. Subsequently, a analysis of variance these estimates was carried out, and repeatability was estimated in the biennia. Repeatability estimate for grain yield in most of the biennia was relatively high, but for ecovalence and regression coefficient it was null or of small magnitude, which indicates that confidence on identification of common bean lines for recommendation is greater when using means of yield, instead of stability parameters.

Abstract:

Tra Vinh Province is an important agricultural production area of the Mekong Delta in Viet Nam, but its economic development is being heavily affected by climate change. In this study, a set of 14 quotas with the Delphi method were used to assess the climate change adaptability of 24 livelihood models (horticulture, animal husbandry, and aquaculture models) in Tra Vinh Province to find livelihood models with the greatest adaptability. The adaptability was calculated using relevant parameters including weighted scores, raw data points, and mean points of each model. Calculations show that two models have great adaptability (CN01 and TS14), twenty models have relatively pretty good adaptability (CN01, CN03, TS02, TS03, TS05, TS06, TS07,TS08, TS09, TS10, TS11, TS12, TS13, TS14, TS15, TS16, TT01, TT02, TT03, TT04 and TT05), two models have average adaptability (TS04 and TS01), and no models have low adaptability. These two successful models can be applied to farmers in Tra Vinh Province but attention needs to be paid to economic issues such as capital or market. These twenty good adaptive and two average adaptability models should be improved for future applications.

Abstract:

The objective of the present study was to propose fuzzy control systems to support the recommendation of cultivars of different agronomic crops. Grain yield data from 23 lines and 2 cultivars of red bean were used to evaluate the applicability of these controllers. Genotypes were evaluated in nine environments in the Zona da Mata region, Minas Gerais State, Brazil. Using the parameters of Eberhart and Russell analysis, fuzzy controllers were developed with the Mamdani and Sugeno inference systems. Analyses of adaptability and stability were carried out by the method of Eberhart and Russell. The parameters obtained for each genotype were submitted to the respective controllers. There were significant genotypes x environments interaction, which justified the necessity of performing an adaptability and stability analysis. For both controllers (Mamdani and Sugeno), seven lines presented general adaptability, while only one presented adaptability to unfavorable environments. It was also found that both inference systems were useful for developing controllers that had the aim of recommending cultivars. Thus, it was noted that fuzzy control systems have the potential to identify the behavior of bean genotypes.

Abstract. Variation function is an important tool that can characterize the spatial correlation of geological variable quantitatively in geo-statistics. In the random inversion process, for different types of blocks and oil fields, choosing the appropriate function type and the corresponding model parameters, to improve the accuracy of inversion results is particularly important. By taking Gu83 block of GuLong oil field as an example, this article analyses common variation functions such as Gaussian, Spherical, Expo and Gen-Expo method and the influence of random inversion results under different variable distance parameters. From the experimental results, the inversion prediction precision will be higher in this block under the following situations: Expo variation function, horizontal variable distance is 3000 meters and vertical variable distance is 3 meters.

Abstract:

Purpose – The power sector needs frontline employees (FLEs) who are adaptable to the dynamic and complex business environments. There is yet to be a study that defines FLE adaptability as a lived in experience. The main purpose of this study is to explore the dimensions of FLE adaptability in power sector. Design/methodology/approach – FLE adaptability being multifaceted and context based, the research is conducted as a qualitative research in an attempt to identify FLE adaptability dimensions. FLE's working in three power utilities in Western, India participated through purposeful sampling frame. Data were collected using interviews, group discussions and open-ended questionnaire and analyzed in line with grounded theory. Findings – The analysis revealed seven dimensions of FLE adaptability. The dimensions being interpersonal aspect of adaptability, service offering aspect adaptability, political aspects of adaptability, social aspects of adaptability, physical aspects of adaptability, group aspect of adaptability and organizational aspect of adaptability. Research limitations/implications – Given the authors' exploratory qualitative approach and small sample size, these findings should be interpreted with caution until they have been replicated in a variety of settings and with multiple methodologies. Participants in this study were drawn from power sector organizations located in Western, India. This may delimit generalizations. Substantial research needs to be carried out in order to fully develop a complete understanding of this important FLE adaptability construct. Social implications – Power sector is one of the major parameters for the development of country. FLEs are one of the main cogs in the efficient management of power sector. This research stresses the need for FLE for adapting to the social fabric of society especially for services which are essential in nature. The new term coined by the researchers is social consciousness which depicts employee social orientation. Originality/value – There is academic scarcity on research that defines FLE adaptability as a lived in experience. In the previous research on employee adaptability, there was a consistent divide between the setting (laboratory vs field), construct dimensionality (uni- vs multidimensional), assessment format (objective task scores vs subjective ratings), and sample (military vs non-military setting). Thus, the previous research on adaptability could not be generalized on the adaptability spectrum of FLEs; hence, this study revisits the attributes of FLE adaptability.

Abstract:

This study proposes an adaptability index system for product development to enhance engineering system management. The index system takes into account the need to reduce the time required to market new products. The adaptability index is defined by the relationship between the time to develop a current product and the time to develop a subsequent (next) one, so that the recommended index will be useful when a new product with shorter execution times than those of the previous one is introduced into the product design and manufacturing process. Implementing an adaptability system’s parameters are derived from responsiveness, competitiveness, engineering, and marketing activities as reflected in adaptability indices. The study’s methodology is case study through questionnaires, interviews, and records. The authors recommend increasing adaptability by reducing complexity through computer-integrated manufacturing, standardization, and others methodologies. The significant outcome based on the case study is the assessment that is enabled by the proposed adaptability index. This index will guide engineering companies in the selection of the most relevant development processes, protocols, production tools, and procedures aimed at reducing the time-to-market required to generate new products, thus allowing it to meet market demand, increase product diversification, and reduce product lifetimes.

Abstract:

Results of research of soft winter wheat new lines of hexaploid level by morphological features, biological properties and biochemical parameters were given. During 2018–2020 in the Northern part of the Central Forest-Steppe of Ukraine the assessment of the general adaptive capacity by the yielding capacity and biological-agronomic traits are given and promising ones are highlighted (Donzorna, Flonormyra, Polezoriana). The new wheat lines have proved themselves well given the consistently high winter, drought resistance, and productivity, coefficient of variation is low, variance of stability, homeostaticity, and selection value – high. According to the biochemical composition of the grain, the studied lines are characterized by medium and high ‘raw’ protein content and gluten content. New selection wheat lines own by the technological indicators (the volumetric bread outut of 100 g of drough, the total baking rating), flour ‘quite satisfactory’, ‘good’, and ‘excellent’ score (Sviatdonivka, Flonormyra). The new wheat line Donzorna is characterized by the presence of 1BL/1RS wheat-rye translocation, which distinguishes it as a donor of resistance to biotic and abiotic factors and requires further more detailed study.

Abstract:

The aim of this study was to identify upland rice genotypes with high stability and adaptability by the GGE biplot method based on the predicted genotypic and phenotypic values. Of the 20 genotypes evaluated, 14 were lines developed by the cooperative program for rice improvement of Minas Gerais and six were controls. The GGE biplot analysis showed that cultivar BRS Pepita and MG1097 were closest to the ideal genotype. In the comparison of the fixed with the random models (% G + GE, prediction error sum of squares and correlation), it was observed that the use of phenotypic means in all comparative parameters indicated a lower predictive potential under simulated imbalance than the use of predicted genotypic values. The conclusion was drawn that BRS Pepita and MG1097 are ideal genotypes for southern Minas Gerais and that the predictive power of the phenotypic means underlying the study of stability and adaptability is lower than of genotypic means.

Abstract:

The hydro turbine generating sets model exists uncertainty in structure and parameters due to its complex structure and operating states multiformity. Especially, the adaptability and robustness of controller is more important for the stabilization control at equilibrium point under given output. Based on Hamiltonian control model of nonlinear hydro turbine generating sets, the L2 disturbance attenuation control is added into the stabilization control to restrain disturbance from model and structure parameters in this paper. The L2 additional control is proved to be asymptotic stability, and its control low is derived. Simulation results show that adding L2 additional control, system can stable to given equilibrium point and has more adaptability and robustness.

Abstract. This article presents the results of a long-term study of a set of oat varieties in the southern forest-steppe zone of the Omsk region. The estimation of parameters of ecological adaptability for protein collection per unit area is given. Purpose. Long-term study of a set of oats varieties in the conditions of the southern forest-steppe zone of the Omsk region according to environmental adaptability parameters calculated on the basis of “protein collection per hectare”. Methods. The research was conducted from 2013 to 2017 in the conditions of the southern forest-steppe of Omsk. A detailed analysis of the adaptability parameters is provided: the indicator “protein collection per hectare” according to Zykin, ecological plasticity index according to Eberhart and Rassel, stability factor according to Lewis, homeostaticity and selection the value of varieties according to Khangildin, relative stability and stability criterion according to Sobolev, intensity according to the method of Udachin. The final adaptability of varieties is estimated by the sum of the ranks obtained by each variety for the studied parameters. Results. The results of the research have shown that they are most adaptive in the southern forest-steppe zone Omsk region filmy varieties Orion, Uranus and Sibirskiy Gerkules (total ranks 34–44) and Sibirskiy golozernyy (total ranks 61). Scientific novelty lies in the study of 13 varieties of membranous and hulless groups of oats, recommended for cultivation in the Omsk region. The collection of protein per hectare is an integral parameter that takes into account two indicators: the actual yield of the variety and the content of crude protein in the grain. Therefore, studies on this indicator are not popular. For the first time, thanks to the adaptive characteristics, varieties are divided according to this characteristic into intensive and extensive. The grouping of varieties depending on the cultivation areas is also given.

Abstract:

The objective of this work was to estimate genetic parameters and to evaluate simultaneous selection for root yield and for adaptability and stability of cassava genotypes. The effects of genotypes were assumed as fixed and random, and the mixed model methodology (REML/Blup) was used to estimate genetic parameters and the harmonic mean of the relative performance of genotypic values (HMRPGV), for simultaneous selection purposes. Ten genotypes were analyzed in a complete randomized block design, with four replicates. The experiment was carried out in the municipalities of Altamira, Santarém, and Santa Luzia do Pará in the state of Pará, Brazil, in the growing seasons of 2009/2010, 2010/2011, and 2011/2012. Roots were harvested 12 months after planting, in all tested locations. Root yield had low coefficients of genotypic variation (4.25%) and broad-sense heritability of individual plots (0.0424), which resulted in low genetic gain. Due to the low genotypic correlation (0.15), genotype classification as to root yield varied according to the environment. Genotypes CPATU 060, CPATU 229, and CPATU 404 stood out as to their yield, adaptability, and stability.

Abstract:

Ground reaction force and impulse measurement is an established method for assessing the physical condition and efficacy of treatment for some animals. The primary aim of this study was to quantify the kinetic parameters of the limbs of healthy cats at different speeds. The second aim was to determine the explicit relationship between the kinetic parameters and speed. Peak vertical force (PVF), vertical impulse (VI), stance phase duration (SPD), and paw contact area (PCA) of each limb (forelimb, F; hindlimb, H) of seven clinically healthy, client-owned cats were recorded in the speed interval of 0.5–2.5 m/s. The cats were encouraged to pass by a pressure-sensitive walkway with different speeds. The results revealed that there were no significant differences in any of the tested parameters between the left and right forelimbs and the left and right hindlimbs. Means and regression formulas of the kinetic parameters with speed were obtained. It was evident that PVF-F and PVF-H increased linearly with speed, while VI-F and VI-H decreased exponentially. SPD-F was practically equal to SPD-H and exponentially decreased with speed. PCA-F increased linearly with speed, and PCA-H was almost invariable. Pressure-sensitive walkway is a suitable and convenient equipment for assessing the kinetic parameters of cats. Variation of these kinetic parameters with speed can be explained by the functional difference for forelimb-dominant and hindlimb-driven.

Abstract:

The purpose of the current study was to consider and identify promising peas lines with high grain productivity and determine their adaptability parameters. The field study was carried out at the FSBSI “Agricultural Research Center “Donskoy”, located in the southern part of the Rostov region during the 4-year competitive variety testing (2017–2020). The objects of the study were 19 breeding lines developed by the FSBSI “Agricultural Research Center “Donskoy”. All lines were of a leafless type. The standard variety was the variety ‘Aksaysky usaty 5’. The lines ‘G-1002’ (2.60 t/ha), ‘G-1003’ (2.81 t/ha), ‘G-1005’ (2.58 t/ha), ‘G-1007’ (2.56 t/ha), ‘G-1014’ (2.63 t / ha) and ‘B-3790/30-3’ (2.54 t/ha) showed a significant excess over the standard variety. The mean productivity in the competitive variety testing of 2017–2020 was 2.41 t/ha. The maximum productivity difference among the years was 1.63 t/ha, or 89% of the mean productivity. This indicates a high contrast of the cultivation conditions over the years. There have been identified the adaptability parameters of the pea lines (stress resistance, genetic flexibility, homeostaticity and breeding value), which exceeded grain productivity of the standard variety. The lines ‘G-1014’ (5.31), ‘G-1007’ (6.12), and ‘B-3790/30-3’ (6.47) showed the highest homeostaticity. The productivity of these lines was more even over the years and it is preferable to cultivate them in contrasting conditions (zones of risky farming, low agricultural background). The lines ‘G-1002’ (4.19), ‘G-1005’ (4.53) were a bit inferior to them. The line ‘G-1003’ had the lowest level of homeostaticity (3.98). The lines ‘G-1014’ (1.49), ‘G-1007’ (1.47), ‘B-3790/30-3’ (1.44) were characterized with the greatest indicator of breeding value. According to the results of the competitive variety testing in 2017–2019, in 2019 the line ‘G-1003’ with the highest grain productivity, was sent to the State Variety Testing under the name ‘Zernogradsky usaty’ in the North Caucasian (6) region. According to the estimation results of the adaptive properties, the variety is responsive to the improvement of cultivation conditions and has been recommended for cultivation in intensive technology.

Abstract:

The adaptability of an earth pressure balance (EPB) tunnel boring machine (TBM) to complex geological strata needs to be evaluated when a tunnel project is set up. It is helpful for better design and more suitable technical parameters of the machine. Because the factors that influence adaptability are numerous and interrelated, their effects also differ; hence, a quantitative assessment of adaptability is generally difficult. In the present study, a method for quantitatively evaluating the excavation adaptability of an EPB TBM was developed using an analytic hierarchy process (AHP) and fuzzy comprehensive evaluation. The method first involves an initial selection of factors that may influence tunnelling. Based on the expert questionnaire and their influence weights determined by AHP, the 10 evaluation indexes from 25 primary indexes were selected to establish the evaluation index system (EIS) including a target, criteria, and index level. Fuzzy membership functions are then derived one after another based on the effect of each evaluation index on the EBP TBM tunnelling process. A fuzzy mathematical method was finally presented to determine the adaptability of an EPB TBM excavation performance. The proposed method was applied to two special sections of diameter 6.98 m excavated by two EPB TBMs in the Shenzhen Metro Line 11 project. The geological exploration shows that these two tunnel sections pass through typical composite strata in Shenzhen. The determined adaptability grades of the EPB TBMs used for composite strata were confirmed by the actual tunnel excavation. It indicates that the developed method is reasonable and useful to evaluate tunnelling adaptability of EPB TBM.

Abstract: The objective of this work was to evaluate the association between estimates of adaptability, stability, and productivity in soybean (Glycine max), and to estimate the repeatability coefficient of these associations between years. A total of 22 genotypes were evaluated in 27 environments in the 2012/2013 crop season and in 19 environments in 2013/2014. In the next crop seasons, 28 genotypes were evaluated in 26 environments, in 2014/2015, and in 25 environments in 2015/2016, totalizing 97 trials. Fourteen methods were evaluated; Spearman correlation coefficients were obtained for the parameters of stability, adaptability, and productivity; and the repeatability coefficients, as well as the minimum number of required environments for a coefficient of determination of 80 and 90%, were calculated. The minimum number of environments required to estimate the degree of association between the parameters was low (seven sites). The methods of Eberhart & Russell and GGE biplot are essential in the evaluation of productivity, adaptability, and stability in soybean because they are able to encompass these aspects using a minimum set of methods. The methods of Annicchiarico (AN), Silva & Barreto (SB), Cruz (CR), and Storck & Vencovsky (SV) can be used to generate complementary information, such as: stability for general, favorable, and unfavorable environments (AN); adaptability in favorable and unfavorable environments (SB, CR, and SV); and average productivity in all environments and in favorable or unfavorable environments (SV).

Abstract We study two-stage robust optimization problems with mixed discrete-continuous decisions in both stages. Despite their broad range of applications, these problems pose two fundamental challenges: (i) they constitute infinite-dimensional problems that require a finite-dimensional approximation, and (ii) the presence of discrete recourse decisions typically prohibits duality-based solution schemes. We address the first challenge by studying a K-adaptability formulation that selects K candidate recourse policies before observing the realization of the uncertain parameters and that implements the best of these policies after the realization is known. We address the second challenge through a branch-and-bound scheme that enjoys asymptotic convergence in general and finite convergence under specific conditions. We illustrate the performance of our algorithm in numerical experiments involving benchmark data from several application domains.

Abstract:

In Brazil, corn is grown in a wide variety of environments, investments and technologies, requiring the development of different types of hybrids. Breeding programs aim to identify genotypes with productive potential combined with better adaptation and stability. The objective of this work was to evaluate 28 hybrids of F2 maize populations, obtained from a complete diallel, together with the eight parent F2 populations and two commercial witnesses, regarding the main agronomic traits: male flowering (FM), plant height and ear ( AP and AE) and grain mass (MG) and estimate the parameters of adaptability and stability. The experiments were developed in 2008/2009 and 2009/2010, in three locations in the State of São Paulo (Campinas, Mococa and Palmital) and the experimental design used was the randomized blocks with three replications. Individual and joint analyzes of variance were performed, the means being grouped by the Scott-Knott test and the parameters of adaptability and stability estimated by the methods of Eberhart and Russell (1966) and Annicchiarico (1992). There was a significant difference (P <0.01) for treatments, locations and interaction between treatments in all evaluated characters. The average for MG was 7,515 kg ha-1, highlighting the hybrid P4 x P1 with MG of 9,095 kg ha-1. The average of hybrids was 40.5% higher than that of parental F2 populations. The hybrids of F2 populations differ in terms of adaptability and stability for MG, with the majority of hybrids (82%) showing general adaptability. The P4xP1 and P4xP2 hybrids are superior to MG and are promising for recommendation in a wide range of environments.

Abstract:

The bionic fuzzy system embeds the biologically active adaptive strategy into the traditional T-S fuzzy system, which increases the active adaptability. On the basis of the researches, an identification model is added to the system, and a hybrid bionic adaptive fuzzy control method is proposed in this paper, which makes the system have biological adaptability and strong anti-interference ability. The adaptive law contains two items: the first one is the general term for adjusting system parameters by using the current state and the second one is a compensation item for the adjustment of system parameters based on the development trend. Lyapunov synthesis method is used to analyze the stability and convergence of system. The design method of fuzzy controller, adaptive laws, and parameter constraints are given. Finally, the effectiveness of the method is verified by simulation of inverted pendulum model.

For the strong external interference and system nonlinearity and other characteristics in mineral inverter system, we propose a simple auto disturbance rejection controller. The dynamic observation of the uncertain factors and external interference in the system model can be made possible by the use of the extended state observer of the auto disturbances rejection so as to improve the system adaptability to the interference. The simulation tests show that the controller has less overshoot, more adjustable transience and wider selection domain in the stable range to the controlling parameters, meanwhile, the controller has greater adaptability to the inverter power system.

Abstract:

Aiming at the problems of poor adaptability and low secret key generation rate of secret key generation scheme based on single characteristic parameter of wireless channel, a secret key generation method based on joint characteristic parameters of amplitude and phase of wireless channel is proposed. This method is based on the single-eavesdropping wireless fading channel model; the joint characteristic model of amplitude and phase of wireless fading channel is established; it detects and extracts the joint characteristic parameters of amplitude and phase of channel, and then the proposed characteristics are quantified by using the equal probability joint quantization strategy of amplitude and phase to generate the secret key random parameters. In this paper, the amplitude and phase joint feature parameter detection method of wireless channel can not only improve the generation rate of random secret key parameters but also make the eavesdropping party’s eavesdropping error rate closer to 0.5. The test results show that the proposed scheme can significantly improve the rate, reliability, and security of generating key random parameters.

Abstract:

AbstractThe study was conducted to estimate the stability, adaptability, productivity and genetic parameters in Slash pine second-generation half-sib families, considering phenotypic traits in early age. Forty-four families from a first generation seed orchard in Colombo-PR, Brazil, were used in this study. Two progenies tests were established in a randomized complete block design. The first test was implemented in March 2009 in Ribeirão Branco, São Paulo state, containing 40 blocks, one tree per plot, 44 treatments (progenies) and 6 controls. Another test was implemented in Ponta Grossa, Paraná state, using the same experimental design and number of plants per plot, and with 24 treatments, 32 blocks. The growth traits evaluated were total height, diameter at breast height (dbh) and wood volume, within five years. The form traits evaluated were stem form, branch thickness, branch angle, number of branches, fork and fox tail five years after planting. Deviance analysis and estimates of stability, adaptability, productivity and genetic parameters were performed using the methods of best linear unbiased predictor (BLUP) and residual maximum likelihood (REML). There was significant variation among progenies for growth and form traits. Considerable genetic variation was detected mainly for wood volume. High coefficients of genetic variation and heritability showed low environmental influence on phenotypic variation, which is important for the prediction of genetic gain by selection. Crosses between different progenies individuals groups will be prioritized for obtaining heterotics genotypes and increase the probability of obtaining high specific combining ability.
