A structured Broyden's-like method for solving systems of nonlinear equations

We suggested a Broyden's-Like method in which the Jacobian of the system has some special structure. In this approach, instead of approximating the whole Jacobian using the Broyden's updating for- mula, we considered an update which only approximates part of the Jacobian matrix that is not easily attained. The anticipation has been to further improve the performance of Broyden's scheme in which the Jacobian of the system has some special structure. The e�ectiveness of our proposed scheme is appraised through numerical comparison with some well known Newton's-like methods.
Evaluation of candidate reference genes for expression study in Saccharum spp. hybrids under heavy metal stress

Heavy metal contamination has been a significant problem limiting agricultural development, but sugarcane has recently emerged as a valuable phytoremediator. To better understand the molecular mechanism behind sugarcane's metal tolerance, it is necessary to analyze the expression of a novel gene(s) by qRT-PCR. Importantly, introducing internal reference gene(s) should be selected based upon gene stable expression, the inclusion of which could enhance both the accuracy and reliability of this method. In this study, 13 candidate genes were selected and evaluated stability of each genes. The results derived by statistical algorithms were then validated by normalizing the expression of metal related gene ScMTP (GenBank Accession No. KP864146), ScMT2-1-3 (GenBank Accession No. JQ627644), ScMPP (GenBank Accession No. CA267392.1) and ScHMA1 (GenBank Accession No. CA156665.1). Collectively, our qRT-PCR results indicated that in heavy metal-exposed sugarcane, APRT was the better single internal control in expression quantification. Moreover, the combination of CAC + CUL provide for a more accurate normalization for gene transcript profiles under these same conditions. The gene expression quantification that included APRT and CAC + CUL suggested that ScMTP had a differential expression pattern, ScMT2-1-3 and ScMPP were slightly inhibited, and ScHMA1 had minimal induction of expression in response to Cd2+ and Cu2+ stresses in sugarcane. Taken together, the suitable reference genes identified in this study will benefit future work aimed at the sugarcane gene functional characterization.
Limited participation or sticky prices? New evidence from firm entry and failures

Traditional models of monetary transmission such as sticky price and limited participation abstract from firm creation and destruction. Only a few papers look at the empirical effects of the monetary shock on the firm turnover measures. But what can we learn about monetary transmission by including measures for firm turnover into the theoretical and empirical models? Based on a large scale vector autoregressive (VAR) model for the U.S. economy I show that a contractionary monetary policy shock increases the number of business bankruptcy filings and failures, and decreases the creation of firms and net entry. According to the limited participation model, a contractionary monetary shock leads to a drop in the number of firms. On the contrary the same shock in the sticky price model increases the number of firms. Therefore the empirical findings support more the limited participation type of the monetary transmission
Embedding Electromagnetic Components into CubeSat Structures Using Additive Manufacturing

Grant funding and National Aeronautics and Space Administration (NASA) launch initiatives for CubeSats make research using satellites research available to universities and projects with relatively low budgets. The small scale of CubeSats—only 10 cm × 10 cm × 10 cm per 1U (one unit) cube, requires efficient use of spacecraft volume. Many CubeSats employ measuring-tape dipole antennas that can only provide omni-directional patterns, or patch antennas that take away surface area needed for solar panels. Additive manufacturing has also become an important topic of research as 3-dimensional printing techniques improve. This work explores techniques for using additive manufacturing to save space on small satellites by embedding electromagnetic components, such as antennas, into the structure elements of a CubeSat. Two primary methods are analyzed, one using finite deposition modeling printing and one using stereolithography. These two types of printers were selected because they are easily accessible and affordable. The filaments for the Finite Deposition Modeling method proved insufficient at this time. However, the stereolithography method successfully produced conductive components embedded within structural elements, including an antenna embedded in a CubeSat cross-brace.
Russian LexicogRaphic Landscape : a TaLe of 12 dicTionaRies

The paper reports on quantitative analysis of 12 Russian dictionaries at three levels: 1) headwords: the size and overlap of word lists, coverage of large corpora, and presence of neologisms; 2) synonyms: overlap of synsets in different dictionaries; 3) definitions: distribution of definition lengths and numbers of senses, as well as textual similarity of same-headword definitions in different dictionaries. The total amount of data in the study is 805,900 dictionary entries, 892,900 definitions, and 84,500 synsets. The study reveals multiple connections and mutual influences between dictionaries, uncovers differences in modern electronic vs. traditional printed resources, as well as suggests directions for development of new and improvement of existing lexical semantic resources.
Visualization of Abstract Audio-visual Information : An Analysis of Art Cognitive Activity Based on Electroencephalogram

Common short signals and special graphic signals are taken as targets to measure changes in the waveforms related to brain's events of artists so as to explore the reasons why artists can create high-quality works from the perspective of electroencephalogram (EEG). It is found that the occurrence of brain wave peaks in ordinary human brains delays and the wave amplitude reduces; under the stimulation of common signal, the occurrence of brain wave peaks in artist’s brains delays and the wave amplitude reduces. However, after taking appropriate amount of alcohol, the brain wave peak time delays, the wave amplitude rises and area of the waveform increases under the stimulation of the graphic signals that they are interested in. The phenomenon of artists’ high creativity often lies in some biographical literary works or historical materials, but few people analyze their principles from a scientific perspective. The author analyzes people’s thinking process from the perspective of thinking signal formation and information processing operation, as well as uses EEG measurement method to study the reasons why artists create high-quality works.
The production of present and absent presences in education

Abstract Drawing on the distinction between absent and present presences, this article contributes to our understanding of how new managerial and performative discourses are played out in a secondary school context in Sweden. The consequences of numerous educational reforms during the last 20 years include a surge of new independent schools and increased segregation between students due to individual school choice. Following international trends, a yearly national municipal school ranking is published, drawing much attention both in the media and on the policy level, intensifying pressure for results at the municipal level. A case study was conducted in one bottom-ranked Swedish secondary school over the 2012-13 school year, focusing on how relationships between students and staff were negotiated in informal spaces and places. The results illustrate how absent presences and present presences are produced in the practice of schooling. The present presences were publication of results, raising merit scores and grading pressure, and the absent presences were the role of the media in the self-image of schools, increased workload for teachers, the misuse of statistical data and demoralization and determination. The results contribute to the understanding of a) the challenges that teachers and schools are faced with as a consequence of the new managerial and performative discourses in educational settings, and b) the means they draw on to face and resist them in their everyday practices.
ADVANCED MANUFACTURING TECHNOLOGIES FOR AUTOMOTIVE STRUCTURES IN MULTI-MATERIAL DESIGN CONSISTING OF HIGH-STRENGTH STEELS AND CFRP

This paper will show basic technological investigations in the field of prepreg-press-technology to manufacture multi-material or hybrid structures for automotive applications. After giving an overview of the process, research results regarding process and forming parameters as well as process control and cycle times will be discussed. Additional results for crash tests, e. g. of double-Z-profiles, demonstrate the crashworthiness of this new class of materials. Finally, detailed concepts for high-volume processing of structural automotive components with multi-material systems will be discussed. With expected cycle times of 2 to 5 minutes the developed approaches for manufacturing local reinforced structures are possibilities to solve the challenges of high-volume manufacturing in the field of CFRP.
A Comparison of the Leadership Practices of Principals of High Schools That Work Schools as Measured by the Leadership Practices Inventory

According to the online Merriam-Webster dictionary, leadership is defined as "the office or position ofa leader, capacity to lead, the act or an instance of leading. " (Merriam-Webster, 2008). Therefore, oneneeds to go to the definition of "lead" to discover the true meaning of leadership. Accordingly, to leadmeans "to guide on a way especially by going in advance, to direct on a course or in a direction, toserve as a channel for a pipe leads water to the house" (2008). Leadership as a verb must meanthat individuals are able to motivate people to advance in some direction. Leadership also implies thatthe leader serves as a channel for people to move forward to accomplish organizational goals. Thiscould include the need to change organizations so they are ripe to achieve these goals. What thismeans in practice is much more difficult. It is the pursuit of what leader’s do that has motivated many aresearcher including the author to investigate leadership in many venues.
RECONSTRUCTION OF 3D MODELS FROM POINT CLOUDS WITH HYBRID REPRESENTATION

Abstract. The three-dimensional (3D) reconstruction of urban buildings from point clouds has long been an active topic in applications related to human activities. However, due to the structures significantly differ in terms of complexity, the task of 3D reconstruction remains a challenging issue especially for the freeform surfaces. In this paper, we present a new reconstruction algorithm which allows the 3D-models of building as a combination of regular structures and irregular surfaces, where the regular structures are parameterized plane primitives and the irregular surfaces are expressed as meshes. The extraction of irregular surfaces starts with an over-segmented method for the unstructured point data, a region growing approach based the adjacent graph of super-voxels is then applied to collapse these super-voxels, and the freeform surfaces can be clustered from the voxels filtered by a thickness threshold. To achieve these regular planar primitives, the remaining voxels with a larger flatness will be further divided into multiscale super-voxels as basic units, and the final segmented planes are enriched and refined in a mutually reinforcing manner under the framework of a global energy optimization. We have implemented the proposed algorithms and mainly tested on two point clouds that differ in point density and urban characteristic, and experimental results on complex building structures illustrated the efficacy of the proposed framework.
Morphological variability within the Kenyan yam (Dioscorea spp.)

Objective: To characterize 43 Kenyan yam cultivars using morphological characters. Methodology and results: Yam cultivars were collected in the major yam growing districts in Kenya. Data of 17 morphological variables measured on these accessions were subjected to multivariate analysis using Principal Component Analysis (PCA) and clustering criterion. The results indicated that the characters contributing most to variability were twining direction, stem colour, spine shape, leaf type and presence or absence of flowering for above ground plant parts; and tuber flesh colour, skin colour, shape of the tuber, hardness of the tuber when cooked, and presence or absence of roots on the tuber surface for the parts below ground. The pruned dendogram generated through agglomerative hierarchical clustering based on the similarity matrix revealed four main groups of this species. One group had only one cultivar which was collected in only one locality in Meru. This is possibly a newly discovered cultivar that has not been previously documented. Conclusion and potential application of findings: This study has showed that there is wide variability in the major yam cultivars grown in Kenya and this can be used to breed higher yielding varieties or screen for cultivars resistant to pests and diseases. The results would also be useful for conservation planning and genetic improvement of the crop. Nevertheless further confirmatory research is required using molecular tools to analyze the diversity detected.
The Role of Phosphorus Slag in Steam-Cured Concrete

Steam curing is an effective method to increase the hydration degree of binder containing phosphorus slag.The role of phosphorus slag in steam-cured concrete was investigated by determining the hydration heat, hydration products, nonevaporable water content, pore structure of paste, and the compressive strength and chloride ion permeability of concrete. The results show that elevated steam curing temperature does not lead to new crystalline hydration products of the composite binder containing phosphorus slag. Elevating steam curing temperature enhances the early hydration heat and nonevaporable water content of the binder containing phosphorus slag more significantly than increasing steam curing time, and it also results in higher late-age hydration degree and finer pore structure. For steam-cured concrete containing phosphorus slag, elevating curing temperature from 60C to 80C tends to decrease the late-age strength and increase the chloride permeability. However, at constant curing temperature of 60C, the steam-cured concrete containing phosphorus slag can achieve satisfied demoulding strength and late-age strength and chloride permeability by extending the steam curing duration.
Investigation of Damping Acceleration Ratio and Site Effects on Seismic Ground Response in the Duzce Region, Turkey

The city of Duzce in Western Black Sea Turkey ha s a experienced of a destructive earthquake with Mw=7.2 in 1999 Duzce earthquake and is situated on the highly active Eursasian plate. The North Anatolian Fault Zone (N AFZ) crosses through Turkey from east to West; earthquake occured on this faul t on August17, 1999 (Kocaeli) and November 12, 1999 (Düzce). Regional geology and sub soil conditions can change the site charecteristics of ground motion. Thus, detect ing he soil magnification at the time of occuring an earthquake, especiallyfor weak soils , is crucial subject for investigators. In this research, one dimensional ground response b ehavior analyses were exucuted for Gölyaka area utilizing the August 17, 1999 Duzce e record with arthquake strong ground motion with DEEP SOIL software. Soil charect ers ics and depth to engineering bedrock at the Gölyaka sites are various and the observed level of the constructional hazard at Gölyaka region at the time of occuring the Duzce earthquake was different as well. Findings revealed that higher magnificatio ns ratios occur at higher periods due to soil behaviour. Result of this research revealed that local geological conditions can magnify ground motion at some periods and, acording to the amplification, and obtained 98 Ali Ateş, Latif. O. Ugur, Rifat Akbiyikli, Inan Keskin, Bur ak Yeşil, Caner Demirdag response spectra can exceed the suggested design sp ectra. As aresult, it is appearent that local site conditions should be taken into consider ation for earthquakeresistant engineering designs on soft soils.
Singleto Multi Clouds for Security in Cloud Computing by using Secret Key Sharing

Now a day Cloud Computing is rapidly using computing technology. For low cost and high-end benefits this cloud computing is utilized. The major issue in this cloud computing is Ensuring the security, because the often store sensitive data with third party cloudproviders but these providers may beuntrusted.Working with single cloud is prevented, because in customer’s perception the failure in service availability and thepossibility of viciousgang in single cloud. To overcome these types of failures, a recent and popular technology is emerged called cloud of clouds or multi clouds or inters clouds. In this paper we illustrated the recent research towards multi clouds from single cloud and addressed possible solutions in security concern.Here we used the SSS (Secret Key Sharing) technique to share the key between servers. From this we can found that there is less attention in the field of multi cloud security compare with single cloud providers. The main intention of this work is to reduce the security risks related to cloud users and to encourage theuse of cloud- of -clouds due to its ability.
The Grassroots of a Green Revolution: Polling America on the Environment

Review: Grassroots of a Green Revolution: Polling America on the Environment By Deborah Lynn Guber Reviewed by Kathy Piselli Vistronix, Inc., USA Deborah Lynn Guber. Grassroots of a Green Revolution: Polling America on the Environment. Cambridge, MA: MIT Press, 2003. 328 pp. ISBN 0-262- 57160-9 (trade paper). US$24.95 What does America think about the environment a generation after the first Earth Day? It was in 1970, and it was the year Lake Erie died. Fast forward to the 21st century and in America concern for the environment seems to be everywhere. The federal government, the states, and many localities have an agency dedicated to environmental protection. The word green appears on packaging, on building plans, and on candidates for public office. And while many still don't care much about the ring-headed newt that only inhabits 300 acres between Yeehaw and Holopaw, people quickly radicalize if everyone in town seems to be getting cancer or the children are developing gastroenteritis. Before considering other possibilities, they cast a suspicious eye on emissions from the local factory or fear pollution in their wells from that smelly operation down the road. But is it a real national consensus, a meeting of minds on how we feel about the protection of our planet? Or is it little more than lip service? This is what Guber sets out to explore in this book, using her knowledge of statistics and polling. The book is divided into two broad sections: attitudes and behavior. In the section on attitudes Guber looks at such questions as: Do Americans favor environmental protection? How much? In tackling these questions, she explains basic polling concepts: what is good data, what is bad , and how questions can be framed to pre-select the response. The end of this section deals with the apparent inconsistency of America's commitment to environmental protection. Guber discusses some technical aspects of information gathering and how these can seem to give a picture of inconsistency in poll responses. That chapter concluding section one sets the stage for section two, on behavior. In this section, Guber puts her knowledge to use dissecting why Americans seem to buy green but fail to vote green, including a discussion of the Bush vs. Gore campaign in 2000. She also looks at some well-known state referendums that passed and others that failed to pass, to find out
Comparison of different nutritional levels and the effect of plant growth promoting rhizobacteria (PGPR) on the grain yield and quality of sunflower

An experiment was conducted in 2007 and 2008 to study the effect of organic, chemical and integrated nutritional levels and Plant Growth Promoting Rhizobacteria (PGPR) on the grain yield and quality traits of sunflower ( Helianthus annuus L.). A total of five nutritional levels, including 100% organic (F1), 25% chemical and 75% organic (F2), 50% chemical and 50% organic (F3), 75% chemical and 25% organic (F4) and 100% chemical (F5), were utilised in the main plot, and two levels of PGPR inoculation (I0, I1) were established in sub-plots, respectively. The treatments were arranged in a split-plot design based on RCB with three replications. The height, leaf area index, biological yield, 1000-seed weight, number of seeds, head diameter, harvest index and qualitative properties (except for the oil content) were superior in the F3, F4, and F2 integrated nutritional levels compared to the completely organic (F1) and chemical levels (F5). In the F3 integrated level, the total increased seed yield (2924.9) was approximately 40% of the lowest seed yield for the F1 level (1777.1). According to the results for the yield, the order was F3>F4>F2>F5>F1 respectively. The highest and lowest contents of oil were observed in the F1 level (51.07) and F3 level (49.35), respectively. The results showed that inoculating the seeds with PGPR increased the qualitative and quantitative properties of sunflower significantly, as compared to the control treatment.
Social representations of female-male beauty and aesthetic surgery: a cross-cultural analysis

The aim of our research program is to investigate the socio-psychological interrelations between female/male beauty and aesthetic surgery in various social groups differentiated not only as a function of gender and education variables (female and male, young people with university training in Arts, Informatics and Sport) in three European countries (Italy, Spain and Romania), but also on the basis of psychological dimensions, like self-rated attractiveness, level of self involvement in the topic of aesthetic-plastic surgery, self-identification with salient cultural referents (like Beauty, Body, Culture, Nature, Soul). The Social Representation framework offers a wide range of heuristic and methodological tools especially called for by both the intimate and social nature of the topics under scrutiny. The study is part of a wider research design following an integrated multi-steps path from exploration to experimentation: 1) a study concerning content, structure, polarity, imagined and emotional dimensions of the Social Representations of female and male beauty and of aesthetic surgery; 2) a study focused on internet discussion forums on the topic of plastic/aesthetic surgery and aimed at investigating the construction of social discourse and negotiation among members of "virtual communities"; 3) a study employing the "body map" tool, an innovative tool with a graphical referent concerning the aesthetic surgery ranking of the various parts of the human body; 4) an experimental study focused on the generative activity of mental images and emotions in the S.R. of beauty and aesthetic surgery. The results here presented come from the multi-method research plan obtained in the first step through: a) the "Associative Network", using "female/male beauty" and "plastic/aesthetic surgery" as inductive words; b) the "Involvement level scale"; c) the "Self-attractiveness Scale"; d) the "Self Identification Conceptual Network". The data were explored by means of multi
