Bending and free vibration analysis of functionally graded plates using a simple shear deformation theory and the concept the neutral surface position

A new first order shear deformation theory is developed for bending and dynamic behaviors of functionally graded plates. Moreover, the number of unknowns of this theory is the least one comparing with the traditional first order and the other higher order shear deformation theories. The equations governing the axial and transverse deformations of functionally graded plates are derived based on the present first order shear deformation plate theory and the physical neutral surface concept. There is no stretching bending coupling effect in the neutral surface based formulation, and consequently, the governing equations and boundary conditions of functionally graded plates based on neutral surface have the simple forms as those of isotropic plates. To examine accuracy of the present formulation, several comparison studies are investigated. It can be concluded that the proposed theory is accurate and simple in solving the static bending and free vibration behaviors of functionally graded plates.
Optimisation of the replenishment problem in the Fashion Retail Industry using Tabu Bees algorithm

The problem of properly allocating several different products in the stores network is one of the crucial processes in the Retail Industry. This means trying to meet market demand and at the same time reducing logistics costs. In this context, main aims of the presented work are to (a) otpimise the replenishment process for the retailer's network of companies with multi product multi store configuration and (b) propose a new algorithm which combines the Basic Bees algorithm, a swarm based optimization technique, with the Tabu Search principles. Attention is focused on the particular case of lost sales and budget constraints for a fashion company. Simulation results show that the use of the Tabu Bees algorithm can guarantee an average 10% improvement in results allowing the model to overcome local minima.
Sard theorems for Lipschitz functions and applications in optimization

We establish a "preparatory Sard theorem" for smooth functions with a partially affine structure. By means of this result, we improve a previous result of Rifford [17, 19] concerning the generalized (Clarke) critical values of Lipschitz functions defined as minima of smooth functions. We also establish a nonsmooth Sard theorem for the class of Lipschitz functions from Rd to Rp that can be expressed as finite selections of Ck functions (more generally, continuous selections over a compact countable set) This recovers readily the classical Sard theorem and extends a previous result of Barbet Daniilidis Dambrine  to the case p 1. Applications in semi infinite and Pareto optimization are given.
Atteinte hepatique, digestive, prise en charge nutritionnelle et troubles de l'oralite chez l'enfant atteint de mucoviscidose

Resume Environ 5 a 8% des patients atteints de mucoviscidose developpent une cirrhose multilobulaire au cours de la premiere decennie. Le depistage annuel de signes d'atteinte hepatique par l'examen clinique, les tests biologiques hepatiques, l'echographie et le suivi sont recommandes afin d'instaurer un traitement par acide ursodesoxycholique et d'identifier les complications: hypertension portale et insuffisance hepatocellulaire. La correction de la malnutrition et la prevention de l'hemorragie digestive sont les principaux objectifs de la prise en charge. Differentes atteintes digestives peuvent etre rencontrees chez ces enfants. Le reflux gastro oesophagien, tres frequent mais souvent neglige, doit etre recherche par pH metrie couplee eventuellement a une impedancemetrie. Des episodes de pancreatite aigue peuvent survenir chez des patients ayant une activite pancreatique exocrine residuelle suffisante. Invagination intestinale aigue, mucocele appendiculaire (accumulation de mucus epais dans l'appendice) syndrome d'occlusion intestinale distale (impaction de selles et de mucus au niveau ileo caecal) syndrome de pullulation bacterienne de l'intestin grele et colite a Clostridium difficile sont a evoquer devant des douleurs abdominales. Sur le plan nutritionnel, la prise en charge preventive et la surveillance attentive de la croissance debutent des le diagnostic. L'alimentation, tout en restant equilibree, doit etre hyper energetique et supplementee en sel. Les extraits pancreatiques lors des repas sont prescrits des l'insuffisance pancreatique exocrine confirmee, de meme que les vitamines liposolubles. En cas de denutrition, la prise en charge nutritionnelle curative par assistance nutritionnelle est d'autant plus efficace qu'elle est precoce, chez des patients a l'etat respiratoire satisfaisant. Les difficultes d'alimentation sont tres frequentes, liees a la physiopathologie de la maladie mais egalement a son retentissement psychologique. Le vecu corporel negatif de l'enfant, la pression medicale et parentale parfois excessive peuvent majorer les refus alimentaires. L'equipe multidisciplinaire doit veiller a proscrire toute attitude contre productive de nourrissage intrusif et valoriser l'instauration d'un climat de plaisir au cours des repas.
ANFIS based prediction model for biomass heating value using proximate analysis components

This paper proposes a new biomass higher heating value (HHV) prediction model using adaptive neuro fuzzy inference system (ANFIS) approach. The 444 data related to wide range biomass based materials are composed from the open literature. The input set for the prediction model is involved of the proximate analysis components such as fixed carbon, ash and volatile matter. Three methods called grid partition, sub clustering and fuzzy c means are considered in the ANFIS model building process, in order to generate fuzzy inference system (FIS) structure. For determining the best ANFIS based prediction model, a number of simulation studies are performed for each FIS method. The optimal result obtained from each method is compared with each other and the results of the models given in the related literature by prediction performance criteria. The results show that sub clustering based ANFIS model is the best biomass HHV prediction model. Its obtained coefficient of regression (R2) and root mean square error (RMSE) are 0.8836 and 1.3006, respectively, in the testing phase. As a conclusion, it can be said that the proposed ANFIS based model is an efficient technique to obtain high accuracy biomass HHV prediction.
Chemical Components and Pharmacological Activities of Terpene Natural Products from the Genus Paeonia
Venue: Molecules

Paeonia is the single genus of ca. 33 known species in the family Paeoniaceae, found in Asia, Europe and Western North America. Up to now, more than 180 compounds have been isolated from nine species of the genus Paeonia, including terpenes, phenols, flavonoids, essential oil and tannins. Terpenes, the most abundant naturally occurring compounds, which accounted for about 57% and occurred in almost every species, are responsible for the observed in vivo and in vitro biological activities. This paper aims to give a comprehensive overview of the recent phytochemical and pharmacological knowledge of the terpenes from Paeonia plants, and enlighten further drug discovery research.
Traffic sign recognition based on weighted ELM and AdaBoost

A novel multiclass AdaBoost based extreme learning machine (ELM) ensemble algorithm is proposed, in which the weighted ELM is selected as the basic weak classifier because of its much faster learning speed and much better generalisation performance than traditional support vector machines. AdaBoost acts as an ensemble learning method of a number of weighted ELMs. Then, an ensemble strong classifier is constructed by the weighted majority vote of all the weighted ELMs. Compared with the existing ELM methods, the proposed algorithm solves the problem of how to train the weighted samples by ELM in multiclass classification directly. Experiments on the German Traffic Sign Recognition Benchmark database demonstrate that the proposed algorithm can achieve a high recognition accuracy of 99.12% with a relatively lower computational complexity than many state of the art algorithms.
On Code Execution Tracking via Power Side Channel
Venue: CCS

With the proliferation of Internet of Things, there is a growing interest in embedded system attacks, e.g. key extraction attacks and firmware modification attacks. Code execution tracking, as the first step to locate vulnerable instruction pieces for key extraction attacks and to conduct control flow integrity checking against firmware modification attacks, is therefore of great value. Because embedded systems, especially legacy embedded systems, have limited resources and may not support software or hardware update, it is important to design low cost code execution tracking methods that require as little system modification as possible. In this work, we propose a non intrusive code execution tracking solution via power side channel, wherein we represent the code execution and its power consumption with a revised hidden Markov model and recover the most likely executed instruction sequence with a revised Viterbi algorithm. By observing the power consumption of the microcontroller unit during execution, we are able to recover the program execution flow with a high accuracy and detect abnormal code execution behavior even when only a single instruction is modified.
Rare Vegetation Degradation within Buffer Zones In Gobustan StateNational Park, Azerbaijan

This paper investigates the spatial change of rare vegetation cover of Gobustan, Azerbaijan. The Gobustan State National Park (Conservation Area) is a nationally important desert/semi desert located west and south west of Baku, Azerbaijan. In 2007 Gobustan was declared a UNESCO World Heritage Site considered being of "outstanding universal value" for the quality and density of its rock art engravings. The Study Area at Gobustan contains a wealth of historical and archaeological sites and is also known for its rare vegetation. This investigation includes monitoring of existing threats to rare vegetation (Global Climate Change, oil and gas exploration, overgrazing of winter and summer pastures by domestic sheep, goats and cattle, pollution, etc. as well the processing of remote sensing data to produce "measured" vegetation indicators. This study has shown that oil and gas infrastructure, in an ecologically important semi arid region, has a negative effect on species abundance and cover of vegetation. Rare vegetation classification within a buffer zone indicates: Plant cover has decreased in the buffer zone and is higher than the Sensitive Area. Bare ground has increased dramatically in the buffer zone whereas in the Sensitive Area it has decreased slightly.
In vivo tracing of organochloride and organophosphorus pesticides in different organs of hydroponically grown malabar spinach (Basella alba L.
Venue: Journal of hazardous materials

An in vivo uptake and elimination tracing study based on solid phase microextraction (SPME) was conducted to investigate the accumulation, persistence and distribution of organochloride pesticides (OCPs) and organophosphorus pesticides (OPPs) in malabar spinach (Basella alba L. plants. Uptake and elimination of the pesticides were traced in leaves, stems and roots of living malabar spinach plants. Root concentration factor (RCF) distribution concentration factor (DCF) and transpiration stream concentration factor (TSCF) were calculated based on the in vivo tracing data. The tracing data showed that the OCPs were much more accumulative and persistent than the OPPs in roots, while they were similarly accumulative and persistent in leaves and stems. RCF values of the OPPs or OCPs were likely to increase with the increase in LogKow values except fenthion. Obtained DCF values indicated that OPPs and OCPs were more accumulative in the organs containing more lipids. TSCF values showed that the translocation of OPPs and OCPs from roots to foliage was firstly dependent on the hydrophobicity of the compounds, but also significantly affected by the water solubility. This is the first study of generating RCF, DCF and TSCF data in living plants by in vivo sampling method, which provides a foundation to promote the application of in vivo SPME and improve understanding of contaminant behaviors in living plants.
Metabolic analysis of two contrasting wild barley genotypes grown hydroponically reveals adaptive strategies in response to low nitrogen stress.
Venue: Journal of plant physiology

Nitrogen (N) is an essential macronutrient for plants. The increasingly severe environmental problems caused by N fertilizer application urge alleviation of N fertilizer dependence in crop production. In previous studies, we identified the Tibetan wild barley accessions with high tolerance to low nitrogen (LN) In this study, metabolic analysis was done on two wild genotypes (XZ149, tolerant and XZ56, sensitive) to understand the mechanism of LN tolerance, using a hydroponic experiment. Leaf and root samples were taken at seven time points within 18 d after LN treatment, respectively. XZ149 was much less affected by low N stress than XZ56 in plant biomass. A total of 51 differentially accumulated metabolites were identified between LN and normal N treated plants. LN stress induced tissue specific changes in carbon and nitrogen partitioning, and XZ149 had a pattern of energy saving amino acids accumulation and carbon distribution in favor of root growth that contribute to its higher LN tolerance. Moreover, XZ149 is highly capable of producing energy and maintaining the redox homeostasis under LN stress. The current results revealed the mechanisms underlying the wild barley in high LN tolerance and provided the valuable references for developing barley cultivars with LN tolerance.
Selenite supplementation reduces arsenate uptake greater than phosphate but compromises the phosphate level and physiological performance in hydroponically grown Oryza sativa L.
Venue: Environmental toxicology and chemistry

The present study evaluates the reduction of arsenate (As[V] uptake in rice seedlings through individual and combined supplementation of phosphate (PO4(3 and selenite (Se[IV] in a hydroponic condition. The toxic response in seedlings receiving As(V) manifested as inhibition in physiological parameters such as water use efficiency, stomatal conductance, photosynthetic assimilation rate, transpiration rate, photochemical quenching, and electron transport rate, along with growth. Arsenic accumulation significantly decreased with Se(IV) treatment (0.5 mg mL( 1) 1 mg mL( 1) and 2 mg mL( 1) in a dose dependent manner (20% 35% and 53% respectively) however, it compromised the PO4(3 level and physiological performance. The lower level of Se(IV) (0.5 mg mL( 1) was relatively beneficial in terms of reduction in As accumulation than the higher level of Se(IV) (2 mg mL( 1) which was rather toxic. Further, decrease in As uptake, replenished the level of PO4(3 and physiological performance in seedlings treated with As+Se+P compared with those treated with As+Se. However, supplementation with only PO4(3 (10 mg mL( 1) and 20 mg mL( 1) along with As(V) was less effective in reducing As accumulation compared with As+Se. Seedlings receiving As+Se+P also exhibited lower thiobarbituric acid reactive substances (TBARS) and electrical conductivity levels compared with both As+Se and As+P. Among all the treatments, the activity of antioxidant enzymes was highest in plants treated with As+Se+P. Hence, the higher antioxidant enzyme activity in As+Se+P along with lower levels of TBARS, H2 O2 and As accumulation are attributed to the competitive reduction in As uptake in the presence of Se(IV) and PO4(3
Caracterisation de la matiere organique contenue dans les particules de la comete 67P/Churyumov Gerasimenko par spectrometrie de masse avec l'instrument COSIMA de la sonde Rosetta

La sonde spatiale europeenne Rosetta, apres un voyage de dix annees, a rejoint le 6 aout 2014 son objet d'etude, la comete 67P/Churyumov Gerasimenko (67P/C G) Afin de l'etudier de maniere intensive durant deux ans, un total de 21 instruments etait embarque sur l'orbiteur Rosetta et l'atterrisseur Philae. Le spectrometre de masse d'ions secondaires a temps de vol, COSIMA (COmetary Secondary Ions Mass Analyzer) etait l'un des instruments de l'orbiteur et a ete concu pour analyser in situ la composition chimique des particules solides ejectees de la comete 67P/C G. L'objectif de cette these est de caracteriser la composante organique refractaire contenue dans les poussieres cometaires, a l'aide de l'instrument COSIMA. Dans le cadre de ces travaux, j'ai mis au point au point et applique une methodologie pour analyser les spectres de masse cometaires, plus particulierement dans le mode positif de l'instrument. A l'aide de cette methodologie, cinq ions organiques d'origine cometaire ont ete detectes et identifies C+ (m/z 12,00) CH+ (m/z 13,01) CH2+ (m/z 14,02) CH3+ (m/z 15,02) et C2H3+ (m/z 27,02) La caracterisation de cette composante organique a ete effectuee a l'aide de spectres de masse de calibration. Les composes de reference utilises dans ces travaux de these incluent des molecules organiques pures et des analogues de la matiere organique cometaire, tels que des echantillons naturels (des meteorites carbonees, une micrometeorite ultracarbonee, de la matiere organique insoluble extraite de meteorites carbonees) et un echantillon synthetise en laboratoire. La matiere organique insoluble extraite des chondrites carbonees est, a ce jour, le meilleur analogue a la matiere organique refractaire contenue dans les particules de 67P/C G. Ainsi, la matiere organique cometaire serait de haut poids moleculaire et le carbone lie dans de grandes structures macromoleculaires. Le carbone est egalement l'un des elements le plus abondant dans les particules avec un rapport C/Si 5,5 +1,4/ 1,2) La comete 67P/C G figure ainsi parmi les corps les plus riches en carbone du systeme solaire. Enfin, un compose specifique a ete recherche, le polyoxymethylene. Cependant, les indicateurs developpes et appliques aux donnees cometaires ne permettent pas de conclure quant a sa presence dans les particules analysees par COSIMA
Elasticity Debt: A Debt Aware Approach to Reason about Elasticity Decisions in the Cloud
Venue: 2016 IEEE/ACM 9th International Conference on Utility and Cloud Computing (UCC)

Cloud elasticity provides the underlying primitives to dynamically acquire and release shared computational resources on demand. Therefore, elasticity constantly takes adaptation decisions to adjust the resource provisioning constrained by quality of service and operating costs minimization. However, dynamic trade offs for resource provisioning rarely consider the value of the adaptation decisions under uncertainty. Part of the problem stems from the lack of a utility driven model to reason about it. In this paper, we introduce the concept of elasticity debt as an approach to reason about elasticity decisions from a utility driven perspective, where we apply the technical debt metaphor in the context of cloud elasticity. Moreover, we extended CloudSim as a proof of concept to show that a debt aware elasticity decision making can achieve a higher utility over time. We provide an elasticity conceptual model that links the key factors to consider when adapting resource provisioning and the potential debts incurred by these decisions. We propose a new perspective to value elasticity decisions in the uncertain cloud environment by introducing a technical debt perspective.
Understanding meaning transfer in celebrity endorsements: a qualitative exploration

Of the three major streams of research in celebrity endorsements, the "Meaning Transfer Model (MTM)" has received the least attention from researchers. In the present study, the authors aim to investigate the basic components of the "Meaning Transfer Model" proposed by McCracken (1986, 1989) and outcome of the flow of meaning through celebrity endorsements.  The authors used an interpretive approach to address four broad research questions framed after a comprehensive literature review. Eight focus group discussions (FGD) (along with embedded word association techniques) were conducted among audience from heterogeneous demographic backgrounds from India. Content and thematic analysis were carried out on the FGD transcripts and the word association test results to generate findings.  The findings indicate seven themes of celebrity meaning, namely, personality, credibility, physical appearance, feelings, performance, values and cogent power. Most meanings were found to be transferred to a brand via the endorsement. The possibility of reverse meaning transfer and the change of celebrity meanings overtime were also observed.  The major contribution of the present study is the development of a measurable and applicable model of meaning transfer in celebrity endorsements, along with a set of testable propositions.  The findings provide a guiding framework for practitioners who would like to use a celebrity endorsement strategy.  This is one of the first attempts to develop a comprehensive model of meaning transfer in celebrity endorsements that includes sub constructs of "meaning" and the moderators in the process.
The Beijing Consensus? How China Has Changed the Western Ideas of Law and Economic Development

Is there a distinctive Chinese model for law and economic development? If so, what does it constitute in the context of concrete policies? Can China's deviation from conventional models be explainable by existing literature? These questions have ignited the debate between the Beijing Consensus and Washington Consensus. This essay provides a systemic, comprehensive account of these seemingly basic yet underexplored questions. Engaging in comparative studies, the author, together with a group of leading legal scholars, create a new set of benchmarks to evaluate the conventional wisdom that the Beijing Consensus challenges and that of the Beijing Consensus itself. Examining various areas of law, including property, securities, company, tax, banking and finance, judiciary, anti corruption, and law and development theories, we conclude that no clear "Beijing Consensus" exists. That said, its challenge to the conventional wisdom invites reformers everywhere to engage in dialogue about the strengths and weaknesses of Chinese policies, helping us to understand what we can and cannot conclude from China's experience.
China's nine dash line, international law, and the Monroe Doctrine analogy

John Mearsheimer has compared China's attitude towards the South China Sea to the Monroe Doctrine of the United States. Mearsheimer does not accord international law much weight and certainly does not regard it as determinative of political outcomes. But many observers of China's disputes in the South China Sea look to international law for rules and processes that could facilitate peaceful resolution of the disputes. In doing so they are variously puzzled, bemused, and/or angered by China's assertion of the nine dash line (Nan Hai Jiu Duan Xian This article draws more broadly on the literature on the Monroe Doctrine, viewing the doctrine as: a unilateral pronouncement of foreign policy; representing resistance; embedded in domestic as opposed to international law; and an assertion of legitimate regional hegemony. Through applying the analogy of the Monroe Doctrine, the article seeks fresh insights into China's legal position in relation to the South China Sea and into the significance of the nine dash line in terms of international law.
