A novel chaotic time series prediction method and its application to carrier vibration interference attitude prediction of stabilized platform

Aiming at the problems existing in previous chaos time series prediction methods, a novel chaos times series prediction method, which applies modified GM(1, 1) model with optimizing parameters to study evolution laws of phase point L1 norm in reconstructed phase space, is proposed in this paper. Phase space reconstruction theory is used to reconstruct the unobserved phase space for chaotic time series by C-C method, and L1 norm series of phase points can be obtained in the reconstructed phase space. The modified GM(1, 1) model, which is improved by optimizing background value and optimizing original condition, is used to study the change law of phase point L1 norm for forecasting. The measured data from stabilized platform experiment and three traditional chaos time series are applied to evaluate the performance of the proposed model. To test the prediction method, three accuracy evaluation standards are employed here. The empirical results of stabilized platform are encouraging and indicate that the newly proposed method is excellent in prediction of chaos time series of chaos systems.
EFFECT OF TEST CONDITIONS ON WEAR PROPERTIES OF STEEL-MATRIX COMPOSITES

The friction coefficient and wear behavior of 316L austenitic stainless steel and 316L steel + 8vol% TiB2 + 1vol% B composites were investigated within a temperature range of 20°C to 800°C. The materials were prepared by the powder metallurgy method. The wear behavior was studied by using a ball-on-disc wear tester at room temperature. The surface before and after wear tests was analyzed using scanning electron microscopy (SEM). The results indicated that the friction coefficient and wear resistance of stel-8TiB2-1B composites depend on the wear test conditions.
ditorial odeling and evaluation of highly complex computer systems

odern computer based systems are characterized by several complexity dimensions: a non-exhaustive list includes scale, architecture, distribution, ariability, flexibility, dynamics, workloads, time constraints, dependability, availability, security, performances. The design, implementation, operation, aintenance and evolution of such systems require informed decisions, that must be founded onto techniques and tools enabling an anticipated knowledge bout the behavior of every subsystem, including hardware, software and interactions, and the whole system, and the relationship of the system and the xternal world, considering workloads, communication, sensing of physical interactions. Performance prediction, and in general behavior prediction, may xploit simulation based approaches or analytical techniques to evaluate in advance the effects of design choices, or variability under different workloads, r emerging behavior, of systems, and provide a valuable support in all the phases of the lifecycle of a system by means of proper modeling approaches. In his Special Issue we present some contributions that offer a glance on modeling and evaluation of complex computer based system, and that have been hosen in order to provide a view on different domains and different approaches, mainly focusing on simulation techniques and related applications. © 2017 Published by Elsevier B.V.
Issues and Challenges in Nurturing Sustainable Rural Tourism Development

The majority of the world's population live in underdeveloped rural areas, which are a concern among many people. On one hand disadvantaged rural population inevitably seek regeneration of livelihood and socio-economic empowerment, on the other hand large numbers of natural and manmade resources in rural areas are highly vulnerable to developmental interventions. Hence, ensuring sustainable development in rural areas in conjunction with increasing developmental needs is a predominant challenge. Alongside, tourism has been widely recommended as a development strategy for underdeveloped areas. Emerging alternative tourism approaches are suggested for development in rural areas. This paper aims to elucidate the issues and challenges faced by rural areas in developing alternative tourism with respect to sustainability. The study adopts a content analysis approach, reviewing documented data in either printed or electronic versions. The documents printed with alternative tourism dimension in rural areas, are purposefully selected for the study. The interpretations and findings are elicited from different settings of the rural areas, which are embodied with diverse natural and human elements. The study was able to reveal different issues and challenges, brought forward by previous researchers who deal with different geographical settings of the world. This illuminates the gap between implementation of alternative tourism and reaching the goals of sustainable tourism development in rural areas.

Export quality upgrading under credit constraints

This paper studies whether credit constraints affect the decision of small and medium size enterprises (SMEs) to upgrade the quality of their exported output with respect to the one sold domestically. We use a detailed firm-level data-set on Italian SMEs reporting information on output characteristics, credit rationing and international activities. Employing . rm credit scores used by banks for their lending decisions, we assess how credit constraints affect export quality upgrading. First, we find that exporting firms are less likely to upgrade output quality, when their credit score worsens. A one standard deviation worsening in the credit score lowers the probability of quality upgrading by more than 35 percent. Second, firms exporting to distant markets cut quality upgrading more sharply when their score worsens. The negative impact of credit constraints is confirmed when taking into account firm heterogeneity in size and other relevant . rm attributes. The main result is robust to endogeneity considerations of the credit score. Overall, our findings suggest that, by impacting export quality upgrading, credit constraints may affect the intensive margin of trade.
Changing plastid dynamics within early root and shoot apical meristem-derived tissue of A. thaliana

Whilst plastids are fundamental to many aspects of plant biology and the production of enhanced crop cultivars, research into the dynamics of non-green plastids has remained somewhat disregarded by the scientific community compared to chloroplasts. They are equally pivotal to normal plant development however, and are now increasingly becoming the focus of research made possible by genetic manipulation and reporter gene constructs. The total plastid content of all plant cells originates from small, undifferentiated plastids termed proplastids found within the meristematic regions of both root and shoot tissue. The cellular regulatory mechanisms controlling the development of plastids in young tissues are poorly understood, especially in the case of non-green plastids in roots. This investigation consequently aimed to elucidate the differences in plastid content, morphology and subcellular localization within epidermal cells derived from the root and shoot apical meristems (RAM and SAM respectively) of Arabidopsis thaliana. Quantification of non-green plastids was facilitated via the use of confocal laser scanning microscopy in conjunction with the expression of plastid-targeted green fluorescent protein driven by a constitutive promoter. Characterization of early seedling development and tissue diversification was also achieved by assessing epidermal cell size relative to developmental progression, ultimately facilitating comparative analyses of plastid dynamics on both a temporal and tissue-varietal basis. The number of plastids in epidermal cells within RAM-derived tissue was shown to increase across regions of cell division before being regulated throughout subsequent zones of elongation and maturing root tissue. In contrast, epidermal cells of the hypocotyl exhibit a more generalized increase in plastid number and less strict maintenance of cell plan area coverage during tissue expansion. The findings presented here suggest the functioning of distinct mechanisms regulating plastid division and growth in relation to cell size within shoot and root apical meristem-derived tissues.
Understanding the Impact of Brand Delistings on Assortment Evaluations and Store Switching and Complaining Intentions

Recently, retailers have begun considering which brands they can delist without reducing customer satisfaction, losing category sales, or increasing store switching behavior. Although several studies have considered assortment reductions, none has explicitly investigated the impact of total brand delistings. Therefore, the authors study the impact of brand delistings on assortment evaluations and store switching and complaining intentions. They execute both a controlled experiment and a survey and find that brand delisting mainly has negative consequences when the delisted brands have high equity, assortment size is limited, the assortment consists of a low proportion of high-equity brands, and the brand delistings take place in categories with high hedonic levels. The authors discuss the theoretical and managerial implications of these findings.
2 What Is an Ontology ? Viewpoints from a Philosopher and from an Ontology Engineer

In 1991, the DARPA Knowledge Sharing Effort ([88], p. 37) envisioned a new way to build intelligent systems. It proposed the following: Building knowledge-based systems today usually entails constructing new knowledge bases from scratch. It could be instead done by assembling reusable components. System developers would then only need to worry about creating the specialized knowledge and reasoners new to the specific task of their system. This new system would interoperate with existing systems, using them to perform some of its reasoning. In

Malaysian Muslim University Students in Jordan Factor Structure of the Spiritual Well-Being Scale : Cross-Cultural Comparisons Between Jordanian Arab

This study reported the differences in factor structure of the Spiritual Well-Being Scale (SWBS) among Jordanian Arab and Malaysian Muslim participants and further examined its validity and reliability. A convenience sample of 553 Jordanian Arab and 183 Malaysian Malay Muslim university students was recruited from governmental universities in northern Jordan. The findings of this study revealed that this scale consists of two factors for the Jordanian Arab group, representing the “Religious Well-Being” and the “Existential Well-Being” subscales, and consists of three factors for the Malaysian group, representing the “Affiliation/Meaning and Purpose,” “Positive Existential Well-Being/God Caring and Love,” and “Alienation/Despair” subscales. In conclusion, the factor structure of the SWBS for both groups in this study was psychometrically sound with evidence of acceptable to good validity and reliability. Furthermore, this study supported the multidimensional nature of the SWBS and the earlier notion that ethnicity shapes responses to this scale.
Cylindrical Silicon Nanowire Transistor Modeling Based on Adaptive Neuro-Fuzzy Inference System (ANFIS)

In this paper, Adaptive Neuro-Fuzzy Inference System (ANFIS) is applied for modeling and simulation of DC characteristic of cylindrical Silicon Nanowire Transistor (SNWT). Device Geometry parameters, terminal voltages, temperature and output current were selected as the main factors of modeling. The results obtained are compared with numerical method and a good match has been observed between them, which represent accuracy of model. Finally, we imported the ANFIS model as a voltage controlled current source in a circuit simulator like HSPICE and simulated a SNWT inverter and common- source amplifier by this model.
Strategies to improve success of in utero stem-cell transplantation in nonimmunodeficient fetuses

1744-165X/$ see front matter a 200 doi:10.1016/j.siny. 2008.03. 002 Summary Most genetic diseases of the lymphohematopoietic system, including hemoglobinopathies, can now be diagnosed early in gestation. However, as yet, prenatal treatment is not available. Postnatal therapy by hematopoietic stem cell (HSC) transplantation from bone marrow, mobilized peripheral blood, or umbilical cord blood is possible for several of these diseases, in particular for the hemoglobinopathies, but is often limited by a lack of histocompatible donors, severe treatment-associated morbidity, and preexisting organ damage that developed before birth. In-utero transplantation of allogeneic HSC has been performed successfully in various animal models and recently in humans. However, the clinical success of this novel treatment is limited to diseases in which the fetus is affected by severe immunodeficiency. The lack of donor cell engraftment in nonimmunocompromised hosts is thought to be due to immunologic barriers, as well as to competitive fetal marrow population by host HSCs. Among the possible strategies to circumvent allogeneic HLA barriers, the use of gene therapy by genetically corrected autologous HSCs in the fetus is one of the most promising approaches. The recent development of strategies to overcome failure of efficient transduction of quiescent hematopoietic cells using new vector constructs and transduction protocols opens new perspectives for gene therapy in general, as well as for prenatal gene transfer in particular. The fetus might be especially susceptible for successful gene therapy approaches because of the developing, expanding hematopoietic system during gestation and the immunologic naiveté early in gestation, precluding immune reaction towards the transgene by inducing tolerance. Ethical issues, in particular regarding treatment safety, must be addressed more closely before clinical trials with fetal gene therapy in human pregnancies can be initiated. a 2008 Elsevier Ltd.

INTENSIVE INSULIN THERAPY FOR STRESS HYPERGLYCEMIA

Hyperglycemia is common in critically ill patients and is associated with increased morbidity and mortality. Intravenous insulin therapy (IIT), adjusted to target the range of 80 to 110 mg/dL, reduces mortality in critically ill adult surgical and medical patients but not in a follow-up trial focuses solely on patients who have septic shock. A recent consensus statement on the treatment of patients who have severe sepsis recommended a target blood glucose level of less than 150 mg/ dL. This is a lower level than prior usual care practices that generally began insulin therapy for blood glucose values exceeding the 180 to 200 mg/dL range during critical illness. A review of published protocols for insulin titration during critical illness showed marked variability in approaches, and the protocols used in the aforementioned trials were paper-based guidelines rather than explicit protocols. Thus it is difficult to know exactly how insulin was dosed during these trials. Furthermore, the nursing effort required to interpret an adequately explicit protocol can be substantial, and IIT increases the risk of hypoglycemia. It remains unclear if self-limited episodes of hypoglycemia contribute to short-term mortality and long-term neurocognitive complications or both. It is increasingly clear, however, that patients who have severe sepsis are at increased risk for hypoglycemia during IIT. In this article, the evidence supporting tight glycemic control and the tools available to accomplish it are reviewed.
in people with type-2 diabetes : a prospective cohort study from ADVANCE Comparison of waist-to-hip ratio and other obesity indices as predictors of cardiovascular disease risk

Aims: The aim of this study was to compare the strength of associations and discrimination capability of body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR) with cardiovascular disease risk in individuals with type-2 diabetes. Methods and results: Eleven thousand, one hundred and forty men and women were followed for a mean of 4.8 years. The Cox proportional hazard models were used to compute the hazard ratios and 95% confidence intervals (95% CI) for one standard deviation (SD) increase in baseline BMI (SD: 5kg/m), WC (SD: 13cm) and WHR (SD: 0.08) with cardiovascular disease risk. After adjustment, hazard ratio (95% CI) for WC were 1.10 (1.03–1.18) for cardiovascular events, 1.13 (1.03–1.24) for coronary events, and 1.08 (0.98–1.19) for cardiovascular deaths. Estimates for WHR were 1.12 (1.05–1.19), 1.17 (1.08–1.28) and 1.19 (1.09–1.31). BMI was not related to any of these outcomes. Although the receiver operating characteristic curve could not differentiate between anthropometric variables (P values 0.24), the relative integrated discrimination improvement statistic showed an enhancement in the discrimination capabilities of models using WHR for cardiovascular outcomes, except for cerebrovascular events. Conclusion: Strengths of associations and discrimination statistics suggested that WHR was the best predictor of cardiovascular events and mortality in patients with type-2 diabetes and BMI the worst.
Discrete Wavelet Transform based High Performance Face Recognition Using a Novel Statistical Approach

Biometrics has gained significant popularity for individual identification in the last decades as a necessity of supporting especially the law enforcement and personal authentication required applications. The face is one of the distinctive biometrics that can be used to identify an individual. Henceforth, Face Recognition (FR) has attracted the great interest of the scientists and academicians. One of the most popular methods preferred for FR is extracting textual features from face images and subsequently performing classification according to these features. A substantial portion of the previous texture analysis and classification studies have based on extracting features from Gray Level Co-occurrence Matrix (GLCM). In this study, we present an alternative method that utilizes Gray Level Total Displacement Matrix (GLTDM) which holds statistical information about the Discrete Wavelet Transform (DWT) of the original face image. The approximation and three detail sub-bands of the image are first calculated. GLTDMs that are specific to these four matrices are subsequently generated. The Haralick features are extracted from those generated four GLTDMs. At the following stage, a new joint feature vector is formed using these four groups of Haralick features. Lastly, extracted features are classified by using K-NN algorithm. As demonstrated in the simulation results, the proposed approach performs promising results in the context of classification.

Niche overlap and temporal activity patterns of social wasps (Hymenoptera: Vespidae) in a Brazilian cashew orchard.

The use of cashew fruits as a glucidic resource by wasps was quantified in an orchard to evaluate temporal overlap for a species-rich guild of social wasps and to determine if temporal partitioning within this guild reduces competition for food resources and facilitates species coexistence. Wasp activity was measured from 06:00 AM to 06:00 PM in a cashew orchard in Northeastern Brazil. A null model approach was used to evaluate temporal overlap for the entire guild of social wasps. Social wasp foraging time was bimodal and concentrated from 09:00 to 12:00 h and from 14:00 to 16:00 h. Overlap of temporal activity distributions between pairs of wasp species ranged from 0.58 to 0.83 (index of Schoener). Through analyses of temporal overlap for the entire guild, niche overlap among all species was greater than expected by chance. Social wasps show relatively high overlap in temporal activity patterns for all pairs of species (always over 50 percent) and in the analysis of the entire guild, average niche overlap among all pairs of species was greater than expected by the null model (n = 10,000 simulations). This indicated that interspecific interactions did not structure this wasp guild, and that responses to daily fluctuations in abiotic variables (e.g. temperature, humidity) likely structure activity patterns of these social wasps.
Party System Institutionalization and Reliance on Personal Income Tax in Developing Countries

This paper explores the effect of party system institutionalization on the relevance of the personal income tax in the tax composition. Based on a fiscal contractualism approach, it is argued that institutionalized political party systems increase the capacity of political actors to credibly commit to fiscal contracts agreed with wealthy taxpayers. Consequently, in countries characterized by institutionalized political party systems wealthy taxpayers accept paying a bigger share of the tax burden, as reflected in a greater relevance of progressive tax types. The analysis of panel data for more than 90 countries from 1990 to 2010 supports this hypothesis, showing that party system institutionalization has an especially significant and strong positive effect on the relevance of the personal income tax where bureaucratic capacity is low. At high levels of bureaucratic capacity the effect disappears. The findings strongly support the claim that, particularly in developing countries, where bureaucratic capacity tends to be limited, taxation is best understood as a problem of credible commitment.
