An Experimental determination of freeplay and its effect on modal complexity and damping

This experiment is designed to address the effects ofjoint related nonlinearities on system parameters. Specifically, the effects of freeplay on the natural frequency, damping, and modal complexity. Many modal analysis techniques assume a system exhibits linear properties that are time invariant. Large structures are commonly constructed with several pinned and bolted joints and these joints can lead to gap and frictional-type nonlinearities. Joint nonlinearities will result in exaggerated damping estimates and complex time-varying mode shapes. These characteristics will result in incorrect modal parameter estimation when estimation assumes linearity. The experiment's intent is to examine nonlinearities and indicate methods of estimating the amount of nonlinearity and the degree of looseness, of a joint, associated with the nonlinearity. A real system, constructed ofmasses, springs, and viscoelastic components will be tested to arrive at these results. The results of this experiment indicated that it is possible to identify freeplay in the system. In addition to this, a new method of determining a system's degree of nonlinearity was developed.
Variation of Insect Assemblages in Fox and Marten Faeces Collected in Southern Poland

Remains of invertebrates, especially insects, are frequently found in carnivores' faeces. Invertebrates are generally restricted to a given area and many factors such as landuse pattern, vegetation structure or even moisture can separate different groups; thus, invertebrates can be used as bioindicators. Forty-five samples of marten and fox scats were analysed for the presence of insect species. Thirty insect species — which were expected to be found — were identified. Canonical correspondence analysis indicated that the factor ‘species’ (i.e., marten and fox) was the main factor determining invertebrate species variation. Redundancy analysis allowed us to identify invertebrate ecological groups associated with these two carnivores. Martens prefer nest-building insects as a supplementary source of food and mainly forage in meadows, whereas foxes foraged in forest with high volumes of insects as well as necrophages. Martens preferred smaller, while foxes preferred lager insects. We conclude that insects found in faeces might play an important role in understanding food and habitat relationships between sympatric predators.
El Niño induced changes to the Bolivar Channel ecosystem (Galapagos): comparing model simulations with historical biomass time series

During a strong El Nino event, nutrient and phytoplankton concentrations around the Galapagos archipelago greatly decrease, while sea surface temperature increases (>7°C). Several species suffer under these conditions, while some benefit and new species appear. To understand the mechanisms behind observed changes, a trophic reference model of the Bolivar Channel ecosystem was forced by a 16 yr (1994 to 2009) satellite-derived time series of phyto- plankton biomass including the El Nino period 1997/98. Emergent changes in model compartment biomasses, as derived from dynamic simulations, were compared to in situ observations of the subtidal communities and marine vertebrates over the study period. Observed population reduc- tions of seabirds (penguins and flightless cormorants) and of several fish groups were well pre- dicted by the simulations, suggesting that bottom-up effects largely control the system during an El Nino event. Observational data also enabled modifying the reference model to an El Nino state model. In this El Nino model, ecosystem size (total energy throughput) was reduced by 70.1%. Overall system characteristics show great similarities with other coastal upwelling systems of the Peruvian coast in that strong El Nino events cause disruptions to trophic flows and keep them at a low (but highly productive) development state.
APPLICATION OF ABRASIVE-WATERJET FOR 3D MACHINING

Abrasive-waterjet (AWJ) is inherently not suitable for complex 3D machining because of the difficulty in capturing the spent abrasives in a three-dimensional space. The spent abrasives still possess considerable residue cutting power that is not only capable of damaging the target workpiece but also a potential safety hazard to the operators. Designing an optimum catcher for a 3D AWJ system to mitigate damage to the target workpiece with complex 3D features is nearly impossible. Although there are commercial multi-axis 3D AWJ systems, they are only limited to machining relatively simple 3D parts. On the other hand, AWJ is amenable to 3D machining. Approaches to take advantage of the 3D machining capability of AWJ while operating within the limitations of safety are discussed in this paper. Generally, the approaches can be divided into two main categories, those with and those without the requirement of added accessories, respectively. For the approach requiring no additional accessories, the workpieces have to be cut multiple times at different orientations or rely on secondary processes to transform them from 2D to 3D shapes. For a number of applications, special accessories were designed to be mounted on the 2D AWJ platform to facilitate 3D machining. PC-based control software was developed to control the operations of these accessories for automation. Machining processes based on these approaches were developed to facilitate 3D machining using a 2D AWJ platform such that the spent abrasives were always shooting in a generally downward direction toward the machine's water tank. By combining more than one accessory, 3D parts with very complex features can be readily machined. Sample 3D parts machined with the above processes are presented to demonstrate the versatility and advantages of AWJ 3D machining.
Proton Damage Effects on Carbon Nanotube Field-Effect Transistors

Abstract : This research investigated the effects of proton damage on single-walled carbon nanotube (SWCNT) transistors. The transistors were irradiated by 1.8 MeV protons to determine the damage induced in the SWCNTs and the device substrate using Raman spectroscopy, and to observe the effect on transistor functionality by measuring current-voltage characteristics. Irradiation of the SWCNT transistors to a fluence of 1x10 to the 13th power protons/cm2 resulted in 67% increase in the Raman D/G peak intensity ratio, while at a fluence of 2x10 to the 13th power protons/cm2 the increase in the D/G ratio was only 18%, likely due to radiation annealing. Current-voltage measurements indicated an increasingly negative threshold voltage shift in SWCNT transistors as a function of proton fluence: -1.3 V after a fluence of 1x10 to the 12th power protons/cm2and -1.9 V after a fluence of 2x10 to the 13th power protons/cm2. The drain current decreased 33% after a fluence of 1x10 to the 12th power protons/cm2 and 58% after a fluence of 2x10 to the 13th power protons/cm2. Charge pumping of the SWCNT transistors revealed a significant error attributed to the combination of the non-uniform distribution of SWCNTs across the gate region, adsorbates on the exposed SWCNT and gate oxide surfaces, and inconsistency in transistor performance. The transistor hysteresis also increased as a function of the proton fluence due to interface and bulk charge trapping. This research provided insight into the effect on SWCNT transistors due to proton irradiations up to a fluence of 2x10 to the 13th power protons/cm2 demonstrating both interface and bulk damage effects.
Importance of Personal Goals in People with Independent Versus Interdependent Selves

This paper investigates how the importance attached to personal goals differs according to the person’s independent or interdependent self. Results of one questionnaire study and two priming studies showed that, overall, independents considered their goals more important than interdependents. A closer analysis revealed, however, that interdependents assigned more relevance to social goals (e.g., harmony with others), than to individual goals (e.g., to be successful), whereas independents attached equal importance to both types of goals.
TIMING OF FIVE PALFA-DISCOVERED MILLISECOND PULSARS

We report the discovery and timing results for five millisecond pulsars (MSPs) from the Arecibo PALFA survey: PSRs J1906+0055, J1914+0659, J1933+1726, J1938+2516, and J1957+2516. Timing observations of the five pulsars were conducted with the Arecibo and Lovell telescopes for time spans ranging from 1.5 to 3.3 years. All of the MSPs except one (PSR J1914+0659) are in binary systems with low eccentricities. PSR J1957+2516 is likely a redback pulsar, with a companion and possible eclipses that last ∼10% of the orbit. The position of PSR J1957+2516 is also coincident with a near-infrared source. All five MSPs are distant ( kpc) as determined from their dispersion measures, and none of them show evidence of γ-ray pulsations in a fold of Fermi Gamma-Ray Space Telescope data. These five MSPs bring the total number of MSPs discovered by the PALFA survey to 26 and further demonstrate the power of this survey in finding distant, highly dispersed MSPs deep in the Galactic plane.
Determinants of Argentina's External Trade

Following the liberalization reforms of the late 80s and early 90s, several emerging market economies have experienced large and persistent trade deficits. This paper focuses on the Argentine experience, examining the extent to which trade imbalances in the 1990s resulted from income and relative price movements, as well as from shifts in foreign trade elasticities associated with structural changes. New estimates of export and import equations are presented using a broader set of variables than previous studies and distinguishing between intra and extra MERCOSUR trade. We find that considerable export sensitivity to world commodity prices, domestic absorption, and economic activity in Brazil, combined with a high income elasticity of imports, are key determinants of Argentina's trade balance.
A Relationship between Stakeholder Management and Business Performance in the Czech Republic

The quality of a relationship with stakeholders is often perceived as a way to a competitive advantage of a company. In other words, many authors have defended a hypothesis that the application of stakeholder management leads to a higher business performance. However, empirical verification of such a hypothesis is not trivial. In the first place, the operationalization of the stakeholder management, quality of the relationship towards stakeholders or the importance of stakeholders is a challenge by itself. This article therefore aims to review empirical research of the relationship between stakeholder management and performance of companies located in the Czech Republic. Unfortunately, the authors conclude that studies with factual results from the Czech Republic are almost none. Only two studies explicitly examine the relationship between stakeholder management and business performance. On top of that, both of these studies suffer from an inadequate research design.
From enterprise concepts to formal concepts

A business enterprise is more than its buildings, equipment or financial statements. Enterprise Architecture frameworks thus include a metamodel that attempts to bring together all the enterprise concepts including the visible entities into a unified conceptual structure. Using a simple case study based on the author's institution, the effectiveness of this conceptual structure is explored. The metamodel is stated in Conceptual Graphs then mapped from these graphs' triples into transitive Formal Concept binaries using the CGFCA software. A misalignment in the enterprise concepts is discovered from the derived formal concepts, pointing towards the wider applicability of this approach.
A preliminary account of the fishes of the Lower Cretaceous Wessex Formation (Wealden Group, Barremian) of the Isle of Wight, southern England

Bulk screening of Lower Cretaceous Wessex Formation (Wealden Group, Barremian) plant debris beds exposed on the south-east and south-west coasts of the Isle of Wight, southern England, has resulted in the recovery of large quantities of isolated chondrichthyan and osteichthyan fish remains. Among these are teeth representing five species of hybodontoid sharks: Egertonodus basanus, Lonchidion breve, Lonchidion crenulatum, Vectiselachos ornatus, and Parvodus heterodon. Six additional hybodontoid tooth morphs have also been identified. Three are assigned to Hybodus sp. and three to Lonchidion sp. At least two of the latter may represent new species. Three neoselachian teeth were also recovered, two of which represent a protospinacid shark and the third a rhinobatid ray. Osteichthyan remains pertaining to four orders, Pycnodontiformes, Lepisosteiformes, Amiiformes and Aspidorhynchiformes, and the genera Coelodus, ? Scheenstia, Caturus, and Belonostomus have also been recorded. A further pycnodont represented by isolated teeth is also present in the assemblage together with other bony fish remains possibly representing additional taxa. Scanning electron micrographs were obtained of specimens representative of each taxon and these, together with a taxonomic list of the fish assemblages recovered from each of the two plant debris beds considered here, are presented. These assemblages are discussed in terms of community structure and the palaeoenvironments they represent. © 2014 The Linnean Society of London, Biological Journal of the Linnean Society, 2014, 113, 872–896.
Molecular docking study of 3,6 bis(3'substituted propoxy) and 3,6 bis (5'substituted pentyloxy) xanthone derivatives as PGHS- 2 inhibitors

Article history: The primary effect of the NSAIDs is to inhibit cyclooxygenase (COX or prostaglandin synthase), thereby impairing the ultimate transformation of arachidonic acid to prostaglandins, prostacyclin, and thromboxanes. Two related isoforms of the COX enzyme have been described, COX-1 and COX-2. Identification of this cyclooxygenase-2 (COX-2) isoform resulted in the development of selective COX-2 inhibitors, with the hope of producing a safer analgesic and anti-inflammatory agent. The principal benefit with the selective COX-2 inhibitors is the production of comparable analgesia and antiinflammatory effects to the nonselective NSAIDs, but with fewer symptomatic gastric and duodenal ulcers and a decrease in gastrointestinal symptoms. In the present work, twelve novel series of xanthone derivatives (A1-A6 and B1-B6) were allowed to dock against PGHS-2(prostaglandin endoperoxide synthase-2) protein (PDB ID: 3LN1) to evaluate their comparative efficacy in terms of docking performance. The results are discussed on the basis of binding energy value.
Evaluating the Haxe Programming Language Performance comparison between Haxe and platform-specific languages

The goal of this paper is to evaluate the performance of Haxe, a cross-platform programming language. By applying an experimental method and a statistical test, we measure and analyze the performance associated with compiling Haxe source code to five of its targets. We find a significant difference in performance between Haxe-compiled and target-specific language code on four out of five targets, two of which in favour of Haxe and two against it. Our findings are useful for developers who are considering adopting the language with the intent of replacing their current development toolbox with it.
Coercion without Lexical Decomposition: Type-Shifting Effects Revisited

Abstract Recently, there has been a surge of psycholinguistic research on the interpretation of type-shifting constructions. We evaluate some of the theoretical and empirical research in this area and propose a reassessment of the nature of type-shifting operations. We argue, in particular, for a structural gap in type-shifting constructions, motivated mainly by the restructuring nature of the verbs employed. We also argue that the putative underspecification (or indeterminacy) of type-shifting constructions is resolved via pragmatic inferences.
Safeart: a digital signature based anti-counterfeit system for art

It is well known that the world of art (paintings, sculptures, graphics etc) is plagued by the virus of counterfeits and this issue is particularly sensible in a country like Italy where art has flourished for centuries and where in the XX century toomany pieces of art of great painters were copied and/or counterfeited and sold for authentic. Counterfeiting is a crime which involve great amounts of money and is perpetrated at all levels, with no exclusion of the greatest art dealers. Once a style or painter has had success it is even too simple to find a epigone which either can copy a single painting or paints according to one particular style. Great examples in Italy are Morandi, De Chirico, Vedova etc. artists with a well defined (and therefore easy to copy) style. In our university we have developed and implemented a digital system which can prove without any doubt the authenticity of a piece of art and which is tamper-proof at all levels.
Whole genome-scale transcriptome analysis of the amyristolyated enterohemorrhagic Escherichia coli O157:H7

2 Animal and Plant Quarantine Agency, Anyang 430-757, Republic of Korea Abstract : Previously, we demonstrated the presence of a second copy of LPS myristoyl transferase in enterohemorrhagic Escherichia coli O157:H7, an important zoonotic diarrheagenic food-borne pathogen; the pO157-encoded ecf (an eae-conserved fragment) and the chromosomally-encoded lpxM (also referred to as msbM ) genes. Although both genes share the same function as an LPS myristoyl transferase, the pO157-encoded ecf is thermoregulated via an intrinsically curved DNA while the chromosomal lpxM is regulated by the PhoP/Q two component regulatory system. However, it is unclear why E. coli O157: H7 carries two copies of LPS myristoyl transferase that are differentially regulated. In this study, a whole genome-scale transcriptome specific to E. coli O157:H7 was carried out for identification of the genes differentially expressed in the amyristoylated E. coli O157:H7. The results identified a total of 110 EHEC genes that were up- or down-regulated in the amyristoylated E. coli O157:H7 strain, including genes associated with virulence (26.36%), metabolism (20.91%), transport (10.91%), signal transduction (4.55%), genetic information processing (3.64%), stress response (2.73%), regulatory function (2.73%), motility/adherence (3.64%), cell envelope (2.73%), cell division (1.82%) and ORFs of unknown function (17.27%). Of particular interest, the expression of LEE pathogenicity island genes was significantly influenced by LPS structural defects.
A Practical Approach to Obtain Defect Matrix for Integrated Circuit Testing

Testing of integrated circuits (ICs) is always a challenge because the continuous miniaturization process and consequently increase of transistor density in microelectronic industry. Nowadays, the industry has to handle with defects that traditional testing approaches can not detect. The result of this imprecise testing process is the increase number of defective ICs that reach the end consumer. To improve the quality of IC testing, a new approach of fault modeling is being adopted which is not based on transistor or logic gate level, but in the IC layout perspective itself. This paper describes the meaning of testing based on layout perspective, particularly, Cell-Aware Testing (CAT) methodology, and a practical approach to obtain the matrix of defects, in which is the set of test patterns to each modelled fault coming from CAT, and that is the CAT’s main result. Experimental simulation results show the matrix of defects obtained for a specific standard cell that can be immediately used by an ATPG.
Designing Human-Computer Interaction for Mobile Devices with the FMX Application Platform

The article contains a survey of methods of the mobile development with the FMX Applica- tion platform, which allows to build multi-platform solutions for the efficient Human-Computer Interaction. The test projects illustrate some important conclusions regarding the design and testing of mobile applications for iOS and Android operating systems. They demonstrate navigation controls designed in the skeumorphic and flat manner with some comparisons based on interviews with users in several age ranges. Test apps provide also touch gestures, sensor integration and connections to remote internet data sources. Some additional considerations about the localization and internationalization of the mobile applications built with the FMX platform were also presented. The proposed implementation of the software engineering methods for the mobile application develop- ment provides new insights, valuable for software developers dealing with the new FMX platform on iOS and Android.
REDUCING X-ray BRIGHT GALAXY GROUPS IMAGES WITH THELI PIPELINE

Before analyzing the images taken with a Mosaic CCD imager, the images have to reach a state which can be used for further scientic analysis. The transformation of raw images into calibrated images is called data reduction. Transforming HEavely Light into Images (THELI) is a nearly fully automated reduction pipeline software (Erben et al., 2005). This pipeline works on raw images to remove instrumental signatures, mask unwanted signals, and perform photometric and astrometric calibration. Finally THELI constructs a deep co-added mosaic image and a weight map. In this poster, THELI data reduction procedures will be reviewed and the reduction process for raw images of seven X-ray bright groups, extracted from GEMS groups (Osmond & Ponman, 2004) obtained by the Wide Field Imager (WFI) mounted on MPG/ESO telescope at La Silla in March 2006 will be discussed.
THE RELATION OF AUDITOR TENURE TO AUDIT QUALITY: EMPIRICAL EVIDENCE FROM THE GERMAN AUDIT MARKET

This study investigates whether and how the length of an auditor-client relationship affects audit quality. Using a sample of 1,071 firm observations of large listed companies for the sample period of 2005 to 2011, the study is one of the first to empirically analyze this auditing issue for the German audit market. The empirical results demonstrate that neither short term nor long term audit firm tenure seems to be a significant factor with regard to audit quality in Germany. In the wake of the ongoing discussion in the European Union regarding the optimal audit tenure length for the quality of the conducted statutory audits, our findings do not support the idea of a mandatory audit firm rotation rule.
