Networked control system for the guidance of a four-wheel steering agricultural robotic platform

A current trend in the agricultural area is the development of mobile robots and autonomous vehicles for precision agriculture (PA). One of the major challenges in the design of these robots is the development of the electronic architecture for the control of the devices. In a joint project among research institutions and a private company in Brazil a multifunctional robotic platform for information acquisition in PA is being designed. This platformhas asmain characteristics four-wheel propulsion and independent steering, adjustable width, span of 1,80m in height, diesel engine, hydraulic system, and a CAN-based networked control system (NCS). This paper presents a NCS solution for the platform guidance by the four-wheel hydraulic steering distributed control. The control strategy, centered on the robot manipulators control theory, is based on the difference between the desired and actual position and considering the angular speed of the wheels. The results demonstrate that the NCS was simple and efficient, providing suitable steering performance for the platform guidance. Even though the simplicity of the NCS solution developed, it also overcame some verified control challenges in the robot guidance system design such as the hydraulic system delay, nonlinearities in the steering actuators, and inertia in the steering system due the friction of different terrains.
The relation between Corporate Social Responsibility and Financial Performance

The last few decades CSR has become increasingly important. A lot of research was done into the relation between CSR and financial performance already, but the results were ambiguous, and no specific research was done on Dutch companies. Through regression models the relation between the independent variable CSR and the dependent variable financial performance is researched. Financial performance is measured by both accountingand market-based measures. Control variables include size, risk, industry and R&D costs. The regression model is performed on different Dutch industries as well, to investigate whether the relation between CSR and financial performance would be different across industries. Lastly, the optimal level of CSR to maximize financial performance is researched. The results suggest there is no significant correlation between CSR and financial performance. It is also ambiguous whether this relation would have to be positive or negative. The relation between CSR and financial performance is indeed different across industries. Based on this research there is no optimal amount of CSR to maximize financial performance since there is no significant correlation between these two.
First record and preliminary information on the biology of the deep - sea African crab, Chaceon gordonae (Ingle, 1985) (Brachyura: Geryonidae) in Saint Peter and Saint Paul Archipelago, Brazil

Several studies conducted in Brazilian oceanic islands have generated many results of great significance for the understanding of these ecosystems. However, most of these studies have been restricted to shallow waters, not going beyond 200 m depth. In this work, seven exploratory deep-water fishing surveys were carried out with bottom traps at Saint Peter and Saint Paul Archipelago, between 2012 and 2014, at depths ranging from 300 to 700 m. During these surveys the presence of a deep-sea crab, identified as Chaceon gordonae was recorded, with 458 specimens being caught. Of the sampled specimens, 252 were males and 206 were females. The carapace length (CL) of sampled crabs measured, on the average, 110.81 ± 14.52 mm for males and 102.00 ± 16.55 mm for females. In general, the β1 parameter of the length-weight relationship indicates a positive allometric growth. A comparison of linear regression between the carapace length and right chela length and width for males suggested a morphological maturity of 108.90 and 110.10 mm CL, respectively, whereas the regression between carapace length and abdomen width in females indicated a size at morphological maturity of 84.00 mm CL.
Emotion Recognition Through ANS Responses Evoked by Negative Emotions

Emotion recognition using physiological responses is one of the core processes to implement emotional intelligence in human-computer interaction (HCI) research. The purpose of this study was to investigate emotion-specific ANS responses and test recognition rate using classification algorithm when negative emotion such as fear, surprise, and stress was evoked. The results of one-way ANOVA toward each parameter, there were significant differences among three emotions in skin conductance response (SCR), number of SCR (NSCR), skin temperature (SKT), and high frequency of HRV (HF). Results of emotion recognition applied to statistical method, i.e. linear discriminant analysis (LDA) and 4 machine learning algorithm, i.e. classification and regression tree (CART), self organizing map (SOM), Naive Bayes and support vector machine (SVM) for emotion recognition showed that an accuracy of emotion classification by SVM was the highest and by LDA was the lowest. This can be helpful to provide the basis for the emotion recognition technique in HCI as well as contribute to the standardization in emotion-specific ANS responses.
The PARAFAC-MUSIC Algorithm for DOA Estimation with Doppler Frequency in a MIMO Radar System

The PARAFAC-MUSIC algorithm is proposed to estimate the direction-of-arrival (DOA) of the targets with Doppler frequency in a monostatic MIMO radar system in this paper. To estimate the Doppler frequency, the PARAFAC (parallel factor) algorithm is firstly utilized in the proposed algorithm, and after the compensation of Doppler frequency, MUSIC (multiple signal classification) algorithm is applied to estimate the DOA. By these two steps, the DOA of moving targets can be estimated successfully. Simulation results show that the proposed PARAFAC-MUSIC algorithm has a higher accuracy than the PARAFAC algorithm and the MUSIC algorithm in DOA estimation.
Can the retirement consumption puzzle be resolved? Evidence from UK panel data

This paper uses UK panel data to shed further light on the fall in spending at retirement (the “retirement-consumption puzzle”). It compares the profiles of spending and well-being at retirement for different groups, defined according to whether retirement is voluntary or involuntary. Where retirement is voluntary, food spending and individual well-being are largely smoothed through retirement; where retirement is involuntary, both food spending and well-being fall. This is consistent with the retirement consumption puzzle being linked to negative wealth shocks. However, there remains one group for whom retirement appears to be voluntary, yet whose spending falls. Fully resolving the puzzle requires a better understanding of how the nature of retirement links to spending and of how different groups substitute leisure for consumption.
Determining the nexus between social entrepreneurship and the employability of graduates

Social entrepreneurs have, in several ways, been re gard d as engines of intense socioeconomic development. They are also famous for intervening w ith projects for society’s problems that are often, either inadvertently ignored or inadequately managed by mainstream society. The issue of graduate employability has gained increased tension around the world especially in emerging markets such as South Africa. Currently, suggestion are that considering the avowed contribution of social entrepreneurs, it may be wor thwhile to start examining how they can assist with graduate employability in South Africa. This paper therefore takes an exploratory, yet focused scrutiny of the social entrepreneurship eco system to find out the likelihood of social entrepreneurs participating in programmes that prep are students for the workplace thereby reducing graduate unemployability. This is a conce ptual paper that has benefitted from an extensive review of literature. Conclusions are dra wn therefrom to suggest that opportunities exist for social entrepreneurs to provide practical , project-based learning opportunities for college and university students so that by the time they graduate they have attained reasonable work-readiness levels that stand them in good stead for employment.

Soil Inorganic Carbon Research Progress in China

Inorganic carbon comprises approximately a third of the total C pool in soils worldwide, largely in the form of pedogenic calcite. Most of the SIC pool is located in arid and semi-arid regions of the world and accumulates as subsurface concentrations of carbonate minerals, predominantly calcite (CaCO3), as the result of minimal leaching through the soil column. The content of SIC is affected by many reasons, climate and land use types are the two major factors. Moreover, human activities play more and more important role in carbon cycle. Understanding the processes governing the storage and flux of this inorganic C pool is crucial to the development of accurate regional and global C budgets.
Inflation differentials in the Euroa area and their determinants: an empirical vies

In this paper, we present evidence on the statistical features of observed dispersion in HICP inflation rates in the Euro area. Our descriptive exercise shows that there is still a remarkable dispersion of HICP inflation rates across the member countries. We find that most of dispersion originates in the non-traded categories of the HICP. This suggests that the main source of dispersion in countries’ headline inflation rates is in those components of the HICP where non-traded goods (services, (public) goods with regulated and administered prices) are more intensely represented. We then examine the determinants of inflation differentials in a panel of the states of the Euro area in 1999–2007 using alternative classifications of this group and three different datasets. The evidence presented shows that output gaps and a proxy for price level convergence were statistically significant. On the other hand, some determinants that were found significant in previous studies (for example Honohan and Lane 2003, 2004; ECB, 2003) has no impact on inflation in our expanded time span (e.g. exchange rate movements) The dispersion of HICP inflation is expected to increase in the coming years as the new EU member states will join the Euro area. There are some risks for these countries connected with the common monetary policy, which is adjusted more to the conditions of stabilized advanced economies forming the core of the Euro area. This creates potential problems for the EU common monetary policy (ECB), in particular negative (positive) interest rates, their repercussions on investment processes, consumption and the possibility of creating asset bubbles.

The intelligent agent technology is used to develop the expert system. The intelligent agents have their own fuzzy knowledge bases. General description of the knowledge base structure and its relations to the information portal databases are presented. Fuzzy inference models used by the intelligent agents of the expert system are listed.
The Role of the Intraoperative Auxiliary Methods in the Resection of Motor Area Lesions

Abstract Objective In recent years, technologies have advanced considerably in improving surgical outcome following treatment of lesions in eloquent brain areas. The aim of this study is to explore which method is best in the resection of motor area lesions. Methods Prospective, non-randomized study Evaluate on 74 patients who underwent surgery to remove lesions around the motor area. Results Total lesion removal was achieved in 68 patients (93.1%). Fifty-four patients (73.9%) presented normal motor function in the preoperative period; of these, 20 (37.3%) developed transitory deficits. Nevertheless, 85% of these patients later experienced a complete recovery. Nineteen patients presented with motor deficits preoperatively; of these, five presented deteriorating motor abilities. Intraoperative stimulation methods were used in 65% of the patients, primarily in cases of glioma. Conclusions The morbidity in patients submitted to resections of motor area lesions is acceptable and justify the surgical indication with the purpose of maximal resection. Intraoperative stimulation is an important tool that guides glioma resection in many cases.
Disentangling the Empirical Evidence between Personality, Work Experience, and Improvisation among Middle Management Government Officers

This study examined the empirical association between personality traits, workexperience, and improvisation. Big five personality traits (Extraversion, Agreeableness,Conscientiousness, Neuroticism, and Openness) and individual work experience werethe independent variables; whereas individual improvisation was the dependentvariable. Data were collected from middle management level of government officersfrom various ministries in Putrajaya, Malaysia. Results revealed that Extraversionand Openness had a significant and positive contribution towards improvisation whileother traits (Agreeableness, Conscientiousness, and Neuroticism) did not demonstratea significant association with improvisation. The findings of this study could contributeto the collective knowledge of management and be useful to both theorists and managers.
Improvement of saccharification and fermentation by removal of endogenous chemicals from pretreated lignocellulosic biomass

The effects of removal of enzyme inhibitors on saccharification of lignocellulosic biomass and fermentation of their hydrolysate were examined with the aim of improving bioethanol production. Hydrothermal-mechanochemical treated woody powders lost their cell structures and lignin was widely and randomly distributed in treated woody powders. Enzymatic reaction resulted in the formation of many cracks and pores on the woody powder surface, and these cavities extended to the interior of woody powders. The concentrations of 3 kinds of phenolic enzyme inhibitors (gallic, tannic and trimesic acids) in the supernatant of the reaction mixture gradually increased during the enzymatic hydrolysis. Cracks and pores of hydrolyzed woody powders were probably routes of inhibitor release to the reaction mixture. Enzymatic saccharification was improved 1.4-fold by ion-exchange resin treatment after 24 hours of hydrolysis, and inhibition of cellulase activity was decreased by 60-95% compared to the control. Ethanol yield was improved 2.2-fold and lactic acid by 1.3-fold compared to corresponding yields using normal hydrolysates.
Vertebral Bone Drilling (Puncture) Attenuates the Intractable Pain Due to Vertebral Fractures without Collapse

Purpose: Osteoporotic vertebral fractures with no sign of vertebral collapse on initial radiographs, which is so-called occult vertebral fractures (VFs), exist. Occult VFs have a high rate of missed diagnosis, and the treatment of these fractures has rarely been discussed in the literature. We evaluated the effects of vertebral bone drilling for the pain due to occults VFs. Materials and Methods: Eighteen patients with painful osteoporotic occult VFs underwent the vertebral bone drilling. We evaluated the clinical outcome by comparing numerical rating scale (NRS) and activity of daily life (ADL) values between before and after the vertebral bone drilling. Comparisons were made by using Wilcoxon signed rank test. Results: The mean baseline NRS and ADL score, and the mean NRS and ALD score after the bone drilling were 8.4 ± 0.8, 2.2 ± 0.6, 2.4 ± 1.0, 4.6 ± 0.5, respectively. Among the patients, we detected significant improvements in NRS pain score and ADL score after the drilling compared with baseline score (p < 0.0002). Conclusion: Vertebral bone drilling at the site of painful vertebral compression fractures alleviated the intractable pain due to osteoporotic occult VFs.
Data Analytics Reporting Tool for CERN SCADA Systems

This paper describes the concept of a generic data analytics reporting tool for SCADA (Supervisory Control and Data Acquisition) systems at CERN. The tool is a response to a growing demand for smart solutions in the supervision and analysis of control systems data. Large scale data analytics is a rapidly advancing field, but simply performing the analysis is not enough; the results must be made available to the appropriate users (for example operators and process engineers). The tool can report data analytics for objects such as valves and PID controllers directly into the SCADA systems used for operations. More complex analyses involving process interconnections (such as correlation analysis based on machine learning) can also be displayed. A pilot project is being developed for the WinCC Open Architecture (WinCC OA) SCADA system using Hadoop for storage. The reporting tool obtains the metadata and analysis results from Hadoop using Impala, but can easily be switched to any database system that supports SQL standards.
Morphological evolution of microscopic dewetting droplets with slip

We investigate the dewetting of a droplet on a smooth horizontal solid surface for different slip lengths and equilibrium contact angles. Specifically, we solve for the axisymmetric Stokes flow using the boundary element method with (i) the Navier-slip boundary condition at the solid/liquid boundary and (ii) a time-independent equilibrium contact angle at the contact line. When decreasing the rescaled slip length $\tilde{b}$ with respect to the initial central height of the droplet, the typical non-sphericity of a droplet first increases, reaches a maximum at a characteristic rescaled slip length $\tilde{b}_{m}\approx O(0.1{-}1)$ and then decreases. Regarding different equilibrium contact angles, two universal rescalings are proposed to describe the behaviour of the non-sphericity for rescaled slip lengths larger or smaller than $\tilde{b}_{m}$ . Around $\tilde{b}_{m}$ , the early time evolution of the profiles at the rim can be described by similarity solutions. The results are explained in terms of the structure of the flow field governed by different dissipation channels: elongational flows for $\tilde{b}\gg \tilde{b}_{m}$ , friction at the substrate for $\tilde{b}\approx \tilde{b}_{m}$ and shear flows for $\tilde{b}\ll \tilde{b}_{m}$ . Following the changes between these dominant dissipation mechanisms, our study indicates a crossover to the quasistatic regime when $\tilde{b}$ is many orders of magnitude smaller than $\tilde{b}_{m}$ .
Phenotypic Characterization of Transgenic Miscanthus sinensis Plants Overexpressing Arabidopsis Phytochrome B

Phytochromes are dimeric pigment proteins with reversible photochromism between red and far-red light-absorbing forms. They are photoreceptors that regulate various aspects of plant growth and development and have been used for biotechnological applications to improve agricultural performance of crops. Miscanthus species have been suggested as one of the most promising energy crops. In this paper, Arabidopsis phytochrome B (PHYB) gene was introduced into Miscanthus sinensis using Agrobacterium-mediated transformation method that we developed recently, with the herbicide resistance gene (BAR) as a selection marker. After putative transgenic plants were selected using the herbicide resistance assay, genomic integration of the transgene was confirmed by genomic PCR and Southern blot analysis, and transgene expression was validated by Northern blot analysis. Compared to nontransformed control plants, transgenic plants overexpressing PHYB showed phenotypes with increased phytochrome B function, which includes increased chlorophyll content, decreased plant height, and delayed flowering. Therefore, these results suggest that Arabidopsis phytochrome B is functional in M. sinensis and provide a method to develop Miscanthus varieties with enhanced agricultural performance using phytochromes.
Robust Humanoid Control Using a QP Solver with Integral Gains

We propose a control framework for torque controlled humanoid robots that efficiently minimizes the tracking error in a Quadratic Programming (QP)formulated as multiobjective weighted tasks with constraints. It results in an optimal dynamically-feasible reference that can be tracked robustly, with exponential convergence, without joint torque feedback, in the presence of non modelled torque bias and low-frequency bounded disturbances. This is achieved by introducing integral gains in a Lyapunov-stable torque control, which exploit the passivity properties of the dynamical model of the robot and their effect on the dynamic constraints of the QP solver. The robustness of this framework is demonstrated in simulation by commanding our robot, the HRP-5P, to achieve simultaneously several objectives in the configuration and the Cartesian spaces, in the presence of non-modeled static and kinetic joint friction, as well as an uncertain torque scale.
Variations of the crustal thickness in Nepal Himalayas based on tomographic inversion of regional earthquake data

Abstract. We estimate variations of the crustal thickness beneath the Nepal Himalayas based on tomographic inversion of regional earthquake data. We have obtained a low-velocity anomaly in the upper part of the model down to depths of 40 to 80 km and proposed that the lower limit of this anomaly represents variations of the Moho depth. This statement was supported by results of synthetic modeling. The obtained variations of crustal thickness match fairly well with the free-air gravity anomalies: thinner crust patterns correspond to lower gravity values and vice versa. There is also some correlation with magnetic field: higher magnetic values correspond to the major areas of thicker crust. We propose that elevated magnetic values can be associated with more rigid segments of the incoming Indian crust which cause more compression in the thrust zone and lead to stronger crustal thickening.
Adaptivity in mimetic difference schemes: one-dimensional transient problems

In this paper, we present an h-adaptive process that defines an optimal mesh to compute the solution transient of convection-diffusion-reaction boundary value problems by using mimetic numerical methods. The estimation of the error, in the spatial variable, is made from the discrete version of the gradient operator. The numerical experiment shows the good behavior of the procedure.
