Dynamic modeling and control of adaptive impedance for human-manipulator interaction with uncertainty

Robots have been used widely in every field in nowadays, such as in transport, machining and some other tasks interaction with the human. Impedance control is a useful method to maintain the dynamic relationship between the end-point of the manipulator and the external environment. Considering the uncertainties of the robot parameters and the environment, this paper proposes an adaptive impedance controller, before the controller designed, the dynamic model of the manipulator is established. Then a experimental and simulation study is made to verify the control algorithm, the results show that the adaptive impedance control is valid and easy to implement.
Etude de la production de 1,3-propanediol par différentes souches de clostridium butyricum

Clostridium butyricum est une bacterie anaerobie stricte, capable de fermenter le glycerol en formant majoritairement du 1,3-propanediol (1,3-ppd). Nous avons recherche a optimiser les conditions de production du 1,3-ppd, un compose a haute valeur ajoutee. Dans un premier temps, nous avons verifie que la souche de la collection DSM 5431 freinait sa production de 1,3-ppd en raison de l'activite limitante d’un glycerol deshydratase due a la formation d'un intermediaire toxique, le 3-hydroxypropionaldehyde (3-hpa). Nous avons deduit de ce premier resultat que l'amelioration des performances fermentaires de clostridium butyricum passait par l'etude de nouvelles souches (e5) isolees au laboratoire. Afin d'ameliorer le rendement molaire en 1,3-ppd nous avons mene des experiences en continu de confermentation sur des melanges glucose-glycerol. L'ajout de glucose permet d'augmenter ce rendement de 0,6 a 0,9. Afin de completer les etudes physiologiques, nous avons purifie chez la souche sauvage les deux activites majeures : la 1,3-propanediol deshydrogenase et le glycerol deshydrogenase. La premiere enzyme a pu etre purifiee jusqu'a homogeneite et sa sequence n terminale a ete etablie. Le glycerol deshydrogenase n'a pu etre purifiee que partiellement. Nous avons mis a profit les resultats precedents pour etablir un protocole de separation rapide de ces deux activites. Il a permis de mieux caracteriser chacune de ces activites pour les deux souches etudiees (sauvage et mutant) et d'expliquer en particulier l'effet toxique du 3-hpa par une grande affinite de ce compose pour les deshydrogenases. En conclusion, clostridium butyricum e5 apparait comme un excellent micro-organisme pouvant servir d'outil biotechnologique pour l'optimisation de la production de 1,3-propanediol quelle que soit la source carbonee.

Simulation multi-échelle de l'interaction polymère-charge

Dans l’industrie du pneumatique, l’ajout de nanoparticules de silice dans la gomme est un procede couramment utilise en raison des proprietes mecaniques remarquables du materiau composite resultant de ce melange. Cependant, l’origine physico-chimique du comportement de ce materiau demeure inexpliquee. Le but de cette these est de sonder ce systeme par simulation moleculaire. Afin de couvrir de larges etendues spatiales et temporelles, inherentes a ce type de materiau, nous avons adopte une strategie de simulation multi-echelle. A partir de trajectoires atomistiques de reference de haute resolution obtenues par dynamique moleculaire, nous construisons des potentiels gros grain realistes en utilisant la methode d’optimisation bayesienne. Nos modeles rendent compte quantitativement du comportement caracteristique de chaines enchevetrees. La demarche multi-echelle, etendue a l’interaction polymere-silice, nous permet de modeliser convenablement les proprietes thermodynamiques, structurales et dynamiques d’un systeme compose d’une nanoparticule de silice, greffee ou non, plongee dans une matrice de polymere amorphe. Ce travail ouvre la voie a la prediction quantitative des proprietes viscoelastiques des caoutchoucs renforces sur des echelles temporelles de l’ordre de la microseconde. Ces dernieres, inatteignables a l’aide d’une description atomistique, sont desormais accessibles a l’aide de nos jeux de potentiels gros grain.
On high-dimensional tests for mutual independence based on Pearson’s correlation coefficient

Abstract This paper investigates a class of statistics based on Pearson’s correlation coefficient for testing the mutual independence of a random vector in high dimensions. Two existing statistics, proposed by Schott (2005) and Mao (2014) respectively, are special cases of the class. A generic testing theory for the class of statistics is developed, which clarifies under what conditions the class of statistics can be employed for the testing purpose. By virtue of the theory, three new tests are introduced, and related statistical properties are discussed. To examine our theoretical findings and check the performance of the new tests, simulation studies are applied. The simulation results justify the theoretical findings and show that the newly introduced tests perform well, as long as both the dimension and the sample size of the data are moderately large.
Intervarietal Variation in Proximate Composition and Antioxidant Potential of Dry Peas (Pisum sativum L)

The present research work was carried out to investigate the proximate composition and antioxidant capacities of newly invented varieties of dry peas. The proximate composition in terms of moisture (7.00-8.50%), ash (3.85-4.97%), fiber (3.8-12.3%) and protein (17.3-18.8%) contents varied significantly with respect to various cultivars. Total phenolic contents (TPC), total flavonoids contents (TFC), percentage inhibition of peroxidation of linoleic acid system, reducing power and DPPH free radical scavenging capacity of different dry peas extracts were found in range of 0.651-0.684 g/100g of GAE, 0.021-0.041 g/100g of CE, 0.713-0.895, 40.051-84.608%, 18.097-24.591 mg/mL, respectively. The amount of TFC, and percent inhibition of per oxidation in linoleic system of different dry peas extracts varied significantly among various cultivars and solvents. From the results of present investigations it is reasonable to say that 80% methanolic extracts of dry peas have exhibited varying degree of antioxidant activity.

Effect of Traditional smoking Method on Nutritive Values and Organoleptic Properties of Sarotherodon galilaeus and Oreochromis niloticus

Fish deterioration or spoilage is one of the greatest problems facing the fishing industry in Nigeria, and since ancient times, smoking has been used to preserve fish products and improve their taste, aroma and colour. The present study was carried out to determine and compare the effects of traditional smoking kiln on nutritional properties and sensory characteristics of Sarotherodon galilaeus and Oreochromis niloticus . A drum type smoking kiln was used for fish smoking. Raw and smoked fish samples were subjected to nutritional analysis and sensory evaluations. Nutritional analysis showed that the crude protein value of smoked O. niloticus (47.69 + 0.13%) was significantly (P<0.05) lower than the smoked S.galilaeus (50.12 + 0.31%) while the crude fat values of S.galilaeus was slightly higher than the O. niloticus . The value of nitrogen free extract of S.galilaeus was higher than the value of O.niloticus with mean values of 18.00 + 0.02% and 0.32±0.01% recorded respectively while the metabolizable energy value of S. galilaeus was significantly (P<0.05) higher than O.niloticus . Sensory evaluation results revealed that smoked S. galilaeus was better in terms of juiciness and overall acceptability while O. niloticus had higher values in term of flavour, tenderness and texture. Based on the results of the study, smoked S. galilaeus and O. niloticus were nutritionally comparable. The results also showed that traditional smoking method is an important preservation method which could enhance the nutritive values of fishes and possibly reduce post-harvest losses. Keywords : Proximate composition, Sarotherodon galilaeus, Oreochromis niloticus, smoking, sensory evaluation.
A Functional Link Between Mental Representation in Long-Term Memory and Cognitive Performance in Working Memory

Although there have been various attempts to identify the perceptual-cognitive mechanisms underlying the superior performance of skilled players over novices in sports, few studies have examined the relationship between mental representations and cognitive performance according to the skill levels of players. The purpose of this study was to investigate the functional link between mental representations in long-term memory and cognitive information processing ability in working memory by analyzing mental representation structure and cognitive performance according to skill level. Twenty male skilled and 25 male novice tennis players participated in this study. Structural dimensional analysis of mental representation was used to evaluate the mental representation structure of a tennis serve. In addition, cognition and movement chronometry was used to assess the cognitive performance of a tennis serve in working memory. Results of the representational analysis showed that the similarity of the skilled players to the standard representation structure was higher than that of novices. Furthermore, results in cognitive performance showed that the skilled players had a higher accuracy and shorter response time compared to the novices. Finally, a significant correlation between the adjusted Rand index and cognition movement chronometry accuracy was observed. Taken together, the mental representation structure and cognitive performance of the skilled players were superior to those of the novices, and mental representations were positively correlated with the accuracy of the cognitive information processing. These results imply that the degree of functional connection between working memory and long-term memory may be used as a perceptual-cognitive factor to explain improvement in performance.
Face liveness detection based on IQA using anova feature selection

In the past few decades, there has been a growing interest in Facial Biometric systems that became a trend in a wide range of technologies like security, access control and surveillance applications. However, Spoof attacks remain the main challenge faced by facial biometric systems. A spoof attack arises when an individual attempt to disguise as someone else by a fake face to get an unauthorized access to the system, a fake face could be a photograph, dummy face or even a video display. To overcome these attacks on such systems, face liveness detection has been produced. There are various ways to detect the face liveness such by texture, motion analysis, determine a scenic clue or by using a thermal sensor. Two methods of detection were identified based on the necessity of user’s cooperation with the system. One is known as intrusive which requires user interaction with the system such in motion detection and the other is non-intrusive were no user effort is needed. For this purpose, image quality assessment has been utilized in the literature for face anti-spoofing detection. Image quality measures (IQMs) are efficient, user friendly, non-intrusive, low cost and present a low degree of complexity in implementation. However, they exhibit some limitations in terms of accuracy and efficiency of the system. Thus, an effective face liveness detection system based on image quality measures has been proposed in this thesis. The system was designed to conquer the limitations of accuracy in a trade off with high and cost ineffective feature extractor. System’s effectiveness was evaluated and benchmarked with other existing related work on CASIA face anti-spoofing database and the expandability of proposed work was further proven on NUAA imposter database. The feature set was selected based on IQMs discrimination power. Analysis of variance (ANOVA) was the statistical tool used to identify these IQMs. ANOVA was applied to find the p-value and F-score for each of the measures. A low p-value (high F score) for a test refers to an evidence to reject the null hypothesis. Then a feature selection strategy was further implemented to minimize the number of measures. The output measures have been employed as a feature extractor to design and develop the face liveness detection system. Image classification for real and fake samples was implemented by support vector machine (SVM). The system is restricted to 2D images. The test results and evaluations have been implemented by the statistical analysis testing and by liveness detection system in terms of accuracy, half total error rate (HTER) and system’s efficeincy. Results have consistently revealed that the proposed method outperforms other detection techniques over different types of spoofing attacks and mediums. The detection accuracy of the system was increased by nearly 13% while the computational load was decreased by approximately 50 % as compared to the state-of-art. The contribution of this work is to ensure the simplicity of detection system and improves its accuracy along with efficiency.
Notes on Fissidens. I and II

In Note I it is shown that the delimitation of the sections Bryoidium, Pachylomidium, Aloma and Semilimbidium subsect. Bryolimbidium is very vague. Consequently they are united. The resulting section contains the type species of the genus Fissidens and the correct name for it is, therefore, Fissidens. In Note II F. bambergeri Schimp. ex Milde, F. firmus Linb. ex Roth, F. herzogii Ruthe in Herzog, F. canariensis Bryhn and F. bilewskyi Pot. Varde are reduced to synonymy under F. minutulus Sull. F. minutulus is described, figured and characterized. Besides, it is compared with F. ovatifolius Ruthe. F. pusillus (Wils.) Milde, F. minutulus Sull. and F. viridulus (Swartz) Wahl, are compared and found to be three distinct species. F. subimmarginatus Phil, is reduced to synonymy under F. exiguus Sull.
Human Male Meiosis and Sperm Aneuploidies

Reports indicate that infertile males, especially those with low sperm count, have an increase in chromosomally-abnormal spermatozoa, therefore the study of these individuals is critical for the field of assisted reproduction. Importantly, aneuploid sperm remain able to fertilize eggs, often resulting in repetitive intracytoplasmic sperm injection (ICSI) failure, recurrent miscarriage, and offspring with increased genetic risk. Most numerical chromosomal abnormalities, especially monosomies, are inviable and result in spontaneous abortion. However, a subset of chromosomal abnormalities can result in live birth, including trisomies 13, 18, and 21 and sex chromosome aneuploidies. Offspring with these aneuploidies typically display physical disabilities, mental retardation, infertility, etc. (reviewed by Martin, 2008). Thus, effective diagnostic methods to detect sperm aneuploidy are of great interest.
Characterization of glycoprotein obtained from the skin mucus of an Antarctic fish, Trematomus bernacchii

The epithelial secretions were collected by scraping the skin of Trematomus bernacchii and seven species of temperate-water fishes and examined for the mucous glycoproteins by gel filtration on a Sepharose CL-4B column. In most cases, the glycoproteins were excluded at the void volume and separated from other mucous constitutents. The yields of the glycoproteins resolved were usually high (35-45%) in the following fishes secreting large quantities of thick mucus from their epidermis: Callionymus lunatus, Misgurnus anguillicaudatus, An· guilla japonica and Leiognathus nuchalis. A fish with hard scales, Carassius auratus, gave a mucous glycoprotein in a low yield (8.4% ). Similarly, the glycoproteins of T. bernacchii, Trachurus japonicus and Acanthogobius flavimanus were obtained in their respective yields of 17.5%, 18.9%, and 14.2% . The carbohydrate composition of the mucous glycoprotein in T. bernacchii was determined to consist of N-acetylneuraminic acid, N-acetylgalactosamine, galactose, mannose, fucose and glucose by analytical methods including thin-layer chromato­ graphy, high-performance liquid chromatography and gas-liquid chromatography. The molar ratio of N-acetylneuraminic acid, N-acetylgalactosamine and galactose (1.0 : 4.8 : 1.2) suggests that major carbohydrate chains are constituted by such monoand disaccharide units as N-acetylgalactosamine, N-acetylneuraminyl-N­ acetylgalactosamine, and galactosyl-N-acetylgalactosamine. These carbohydrate units may link through 0-glycosidic linkage to threonine and serine residues in the core polypeptide. Assuming such a structure of the carbohydrate unit, it becomes probable that the mucous glycoprotein secreted from T. bernacchii epithelial tissue has a similar ability to depress freezing point for the antifreeze glycoproteins present in the serum.
Is Oreochromis niloticus invading the Samborombón Bay, Río de la Plata, Argentina?

The Nile tilapia (Oreochromis niloticus) is a species widely cultivated worldwide. In recent decades it was an increasing development of fish farming of this species and the red variety in Argentina and Uruguay. From January to March 2010, four specimens of O. niloticus were captured in the south boundary of Samborombon Bay (S 36° 17 W 56° 46 ), which is the external sector of the Rio de la Plata. Probably the collected specimens were released accidentally from hatcheries placed on the banks of aquatic environments in communication with the Samborombon Bay. The patterns and mechanisms of species dispersal are of significant interest, while the interactions among factors determining invasion success often remain poorly understood. Invasion success is influenced by the ability of invading specie to withstand, interactions with native species and oceanographic characteristics of the new habitat. Of four specimens obtained two were females, one in spawning stage. This is the first record of Nile tilapia from a natural environment in Argentina and could indicate the beginning of a new invasion by a non native species.

Risk factors for human giardiasis in two Romanian counties

Abstract The hereby paper analyses the risk factors most often associated with the appearance of the disease produced by the flagellate protozoan Giardia lamblia in human population: gender, age and patient’s place of origin. Applying the Student t-test in order to verify the hypothesies Ho (null hypothesis-the averages of the two paired series do not differ significantly) and Ha (the alternative hypothesis-the averages of the two paired series differ significantly) leads to the acceptance or rejection of one of them. The observational data had been recorded during 2009-2010 years on to the County hospitals of Tulcea and Vâlcea counties in Romania, the survey being based on more than 5000 human subjects: adults and children of both sexes. More such studies like ours should be carried out in Romania in order to have a better understanding of the epidemiology on parasitic diseases which affect the human population of both sexes, all ages and all life environments.

Non-exponential discounting portfolio management with habit formation

This paper studies the portfolio management problem for an individual with a non-exponential discount function and habit formation in finite time. The investor receives a deterministic income, invests in risky assets, buys insurance and consumes continuously. The objective is to maximize the utility of excessive consumption, heritage and terminal wealth. The non-exponential discounting makes the optimal strategy adopted by a naive person time-inconsistent. The equilibrium for a sophisticated person is Nash subgame perfect equilibrium, and the sophisticated person is time-consistent. We calculate the analytical solution for both the naive strategy and equilibrium strategy in the CRRA case and compare the results of the two strategies. By numerical simulation, we find that the sophisticated individual will spend less on consumption and insurance and save more than the naive person. The difference in the strategies of the naive and sophisticated person decreases over time. Furthermore, if an individual of either type is more patient in the future or has a greater tendency toward habit formation, he/she will consume less and buy less insurance, and the degree of inconsistency will also be increased. The sophisticated person's consumption and habit level are initially lower than those of a naive person but are higher in later periods.
