Design Parameter to Develop Secondary Flow in Twin Screw Extruder

Possibility of generating strong secondary flow in mixing region of twin screw extruder was analyzed numerical FEM simulation using the commercial CFD package Polyflow. Adaptive remeshing - mesh superposition technique was used to generate high density polyethylene velocity profiles in simulation. Clearance between barrel wall and mixing element was increased gradually and observed the changes in flow pattern. Mixing element tip radius was varied by ratio to generate convergence flow in the clearance region and visualize the strength of secondary flow profile. Strong secondary flow at the clearance channel can generates elongation flow and improves the dispersive mixing; helps to decrease the screw length by minimizing kneading disc number in mixing section.
Wideband ferrite substrate integrated waveguide isolator using shape anisotropy

A new variable bandwidth isolator implemented in a substrate integrated waveguide is presented. This design utilizes the shape anisotropy of ferrite multiple slabs to increase the demonstrated isolation bandwidth from ∼100 MHz to ∼1.2 GHz, over 10× increase, using commercially available polycrystalline ferrites. Over 10 dB of isolation with 2–3 dB of insertion loss is demonstrated. This device is also featured as a prototype fabrication with bulk substrates rather than a printed circuit board approach resulting in significant cost and time savings.
Experimental methodology to measure damping in microstructures by using the actuation force hysteresis curve

The study of damping in MEMS (micro electro-mechanical systems) is crucial for dynamic response prediction and functional parameters estimation as switch and release time, resonance and quality factor. Geometrical features (borders, perforations, anchors, etc.) complicate the airflow and impose to validate the results calculated or simulated with models. Fluid damping is the dominant dissipation source, accompanied by structural dissipations, thermo-elastic damping, anchor losses, surface effects and electric losses. In literature, the damping coefficient of MEMS is generally derived from the peaks of the structural frequency response function (FRF) by the half power method. Despite the wide usage of this approach, it is affected by two main drawbacks: highly precise and automated detection instruments are needed, and it is applicable only in resonance conditions. The method presented here is based on the measurement of damping from the hysteresis cycle of the actuation force; it applies in the time domain and works at any frequency and vibration amplitude. The effectiveness of this methodology on MEMS is proved by comparing the damping results with those provided at resonance conditions by the half power method. The samples, designed by the authors, are gold microplates with square holes and elastic springs. The measurements are conducted by the laser vibrometer Polytech MSA500. The comparison shows very good agreement with the damping coefficients calculated with the traditional approach (differences within 2% at resonance).
An Analysis of Unstable Flow Dynamics and Flashback Mechanism Inside a Swirl-Stabilised Lean Burn Combustor

A modern lean burn combustor for propulsion application using a multi-swirler fuel injector system is studied under partially premixed combustion conditions. Combustion induced vortex breakdown (CIVB) plays an important role in establishing the near-field aerodynamic characteristics of lean burn fuel injectors, influencing fuel/air mixing and flame stability. The precise nature of the vortex breakdown can take on several forms mainly consisting of a precessing vortex core (PVC) and the appearance of multiple helical vortices formed in the swirl stream shear layer. In the present study a numerical investigation is carried out with an unsteady Reynolds-averaged Navier Stokes (URANS) solver to capture the evolution of the PVC in the vicinity of the air blast atomizer of the injector and the helical vortex patterns inside the combustor. PVC suppression is captured causing upstream flame propagation and a sudden rise in the temperature near the injector end. The existence of hot-spots is reported near the injector end which can increase NOx production and also cause possible damage to the injector assembly itself. The unsteady dynamics of the PVC, which significantly influences fuel efficiency and emissions, are analyzed for a relatively long period of real time. The variation of velocity along the axis of the combustor confirming upstream flame propagation in to the injector is plotted. Mass weighted average temperatures across different planes in the combustor are monitored as target functions. The influence of different time-step sizes on the prediction of the temperature across these different planes is also presented. For this lean burn combustor using a complex multi-swirler fuel injector system, the results demonstrate the formation of a startup PVC in the vicinity of the air blast atomizer of the injector, its unstable mode of excitation, sustainment and suppression due to CIVB over a period of time and its strong influence on injector near-field aero-thermodynamics.Copyright © 2010 by Rolls-Royce plc
Predicting Recessions and Recoveries in Real Time: The Euro Area-Wide Leading Indicator (ALI)

This study develops a new monthly euro Area-wide Leading Indicator (ALI) for the euro area business cycle. It derives the composite ALI by applying a deviation cycle methodology with a one-sided band pass filter and choosing nine leading series. Our main findings are that i) the applied monthly reference business cycle indicator (BCI) derived from industrial production excluding construction is close to identical to the real GDP cycle, ii) the ALI reliably leads the BCI by 6 months and iii) the longer leading components of the ALI are good predictors of the ALI and therefore the BCI up to almost a year ahead and satisfactory predictors by up to 2 years ahead. A real-time analysis for predicting the euro business cycle during the 2008/2009 recession and following recovery confirms these findings. JEL Classification: E32

Homodyne FMCW radar range resolution effects with sinusoidal nonlinearities in the frequency sweep

This paper presents analysis and simulation results describing the effects on the range resolution of linear frequency modulated continuous wave (FMCW) homodyne radar due to sinusoidal nonlinearities in the frequency sweep. Short range applications such as collision avoidance and missile seekers use homodyne FMCW radar. Good range resolution is important to target-to-clutter contrast and to support target discrimination. In FMCW radar systems, range resolution depends on the transmitted bandwidth, the processed overlap between the transmitted and received frequency sweeps, the receiver frequency resolution, and the frequency sweep linearity. Frequency sweep nonlinearity is often the limiting factor in FMCW radar range resolution. This paper specifically addresses the effect of both the amplitude and the frequency of the sinusoidal frequency sweep nonlinearity on the target return spectrum and consequently the range resolution. These results are applicable to the design of modem closed-loop linearizers such as those used for varactor tuned Gunn diode oscillators in millimeter wave (MMW) FMCW radars, because after piecewise linear compensation the residual errors are approximately sinusoidal.
The Correlation between the Number of Asphalt Mixing Plants and the Production of Asphalt Mixtures in European Countries and the Baltic States

The transport infrastructure’s pavement is made of asphalt layers, placed and compacted. The asphalt mixture is produced in an asphalt mixing plant (AMP) using expensive technological equipment which, when it becomes obsolete and worn out, is replaced with new equipment. One of the main problems related to the replacement process is that when it comes to purchasing new AMPs, the decision making involved is, in most cases, highly intuitive due to a lack of clearly defined criteria. In order to remedy this situation, this work presents an analysis of the correlation between the number of AMPs and the production of asphalt mixtures. Firstly, a correlation analysis was performed based on the European Asphalt Pavement Association (EAPA) data. Secondly, the current situation with the AMPs in European countries was analysed. Furthermore, a case study was performed and a system of nine criteria was created to identify why/when road construction companies operating in the Baltic States buy new AMPs. The weights of the criteria have been established by applying the Analytic Hierarchy Process (AHP) method. It was found that the most important criterion during the decision-making process for road construction companies is increased requirements for improving the quality of the asphalt mixture produced (criteria weight 25.0%). With a weight of 20.6%, the second vital criterion is the possibility of receiving support from European funds. The third criterion is the expectation of having a sizeable asphalt-paving site (weight 20.4%). The other six criteria are also significant, their weights varying between 1.6% and 13.5%. The industrial companies can use the obtained results for designing, producing and selling AMPs and adjusting strategic business plans.
Energy storage for long endurance AUVs

Energy storage is a key issue for long endurance autonomous underwater vehicles. Mission duration, speed through the water and sensor and payload capabilities are constrained by the energy available, which in turn is governed by the characteristics of the energy source or sources and the mass and volume that the vehicle designer can devote to the energy system. Tensioned against these technical issues are those of cost, operational life, ease of use, maintainability, safety, security and continuity of supply of the items forming the energy system. This paper focuses on primary and secondary electrochemical batteries, how existing vehicles have constructed their energy storage systems and seeks to establish whether electrochemical cells alone will be able to provide the necessary energy at an affordable cost for future long endurance AUVs and the missions being considered.
Overlap of Granulomatosis With Polyangiitis and IgA Nephropathy

Acute glomerulonephritis is a constellation of renal disorders which are precipitated by an immunologic mechanism triggering inflammation and proliferation of glomerular tissue resulting in damage to the basement membrane, mesangium, or capillary endothelium. Two of the most well-known manifestations of glomerulonephritis are granulomatosis with polyangiitis (GPA) and IgA nephropathy (IgAN). To our knowledge, these diseases are often found separately and are rarely diagnosed in the same patient. Here, we discuss a case of a 35-year-old male who presented and was diagnosed with simultaneous GPA and IgAN. His renal biopsy was significant for extensive, crescentic, and necrotizing glomerulonephritis and IgA staining on immunofluorescence indicating severe renal damage. Despite full immunosuppressive therapy, our patient failed to recover his renal function. In our case, we hope to raise awareness of these disorders and early recognition of the clinical features. We believe that this case would prompt providers to pursue diagnostic workups to detect these diseases early on, especially when symptoms progressively worsen and become systemic. As demonstrated in our patient, delay in diagnosis can lead to irreversible damage to a patient’s renal function, especially when two types of glomerulonephritis are present.
Dark and Light triad: relationship between personality traits and addiction to mobile phones, video games and internet

The present study analyzed the effects of Light and Dark Triad traits scores on Internet Gaming Disorder, intrapersonal and interpersonal conflicts related to internet consumption, conflicts, and communicational emotional usage related to mobile phones. Light Triad traits include Faith in Humanity, Humanism, and Kantianism. Dark Triad traits include Machiavellianism, Narcissism, and Psychopathy. The study used a quantitative approach with a non-experimental design. The sample consisted of 450 adults of the Honduran population, of which 55.33% were women, and 44.67% were men, with an average mean age of 25.52 years (SD=6.79). Results indicate that Machiavellianism and Psychopathy scores have significant effects over Internet Gaming Disorder scores. Intrapersonal conflicts related to internet consumption were negatively affected by Narcissism scores and positively affected by Machiavellianism. Psychopathy scores explained interpersonal conflicts related to internet consumption scores. On the other hand, conflicts related to mobile phone usage were negatively affected by Narcissism and Kantianism, while Machiavellianism had positive effects. Finally, communicational emotional usage related to mobile phones was significantly affected by Machiavellianism. These results are discussed according to their implications for the behavioral sciences.

EFECTO LÁTIGO EN LA PLANEACIÓN DE LA CADENA DE ABASTECIMIENTO, MEDICIÓN Y CONTROL

The bullwhip effect, is one of the causes of the fluctuations experienced by the projection of demand as the market moves away along the supply chain (SC), as a result of lack of coordination and synchronization between the agents (supplier, manufacturer, distributor, wholesaler, retailer). This situation directly affects the strategic and operation al planning proposed by the member organizations the SC, in relation to response time, storage management, hidden logistics costs and negotiation processes, among others things. Undoubtedly, one way to mitigate this effect is that the SC has a system of management information synchronized under a collaborative environment for negotiation. This business scenario usually occurs does not always easy, reason why we propose a method of measurement and control based in techniques of System Dynamics specifically the application of exponential smoothing and Holt-Winters. These methods allow us to transmit the same demand patterns received, without any variation.

Realisation of a holographic microlaser scalpel using a digital micromirror device

Modern spatial light modulators (SLM) enable the generation of more or less arbitrary light fields in three dimensions. Such light fields can be used for different future applications in the field of biomedical optics. One example is the processing/cutting of biological material on a microscopic scale. By displaying computer generated holograms by suitable SLMs it is possible to ablate complex structures into three-dimensional objects without scanning with very high accuracy on a microscopic scale. To effectively cut biological materials by light, pulsed ultraviolet light is preferable. We will present a combined setup of a holographic laser scalpel using a digital micromirror device (DMD) and holographic optical tweezers using a liquid crystal display (LCD). The setup enables to move and cut or process micro-scaled objects like biological cells or tissue in three dimensions with high accuracy and without any mechanical movements just by changing the hologram displayed by the SLMs. We will show that holograms can be used to compensate aberrations implemented by the DMD or other optical components of the setup. Also we can generate arbitrary light fields like stripes, circles or arbitrary curves. Additionally we will present results for the fast optimization of holograms for the system. In particular we will show results obtained by implementing iterative Fourier transform based algorithms on a standard consumer graphics board (Nvidia 8800GLX). By this approach we are able to compute more than 360 complex 2D FFTs (512 × 512 pixels) per second with floating point precision.
Proposal for a Carbon Fibre Reinforced Composite Bridge across the Strait of Gibraltar at its Narrowest Site

Tremendous progress has been made in the construction of long span bridges within the last two centuries. In this evolution structural concepts and strength of materials used have played key roles. The limiting span is defined as that span at which the structural system will just support itself. Comparison is made between limiting spans of cable-stayed bridges made of steel and of advanced composites. The use of advanced composites would allow the tripling of the limiting span in comparison to steel structures. To compare the quantities of material required for the cables of suspension and cable-stayed bridges, calculations are performed. The results are shown within a proposal for an advanced composites bridge across the Strait of Gibraltar.
Biologia de Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) em Algodoeiro de Fibra Colorida Tratado com Silício

A lagarta Spodoptera frugiperda (Smith) e praga-chave da cultura do milho e a cada ano sua ocorrencia na cultura algodoeira tem aumentado, causando danos severos desde a fase de plântula ate a maturacao. Objetivou-se com este trabalho avaliar o efeito do silicio na biologia de S. frugiperda em algodoeiro de fibra branca e colorida. Os bioensaios foram conduzidos com duas cultivares de algodao, a BRS Cedro (fibras brancas) e BRS Verde (fibras verdes), com e sem aplicacao de silicio. O silicio foi aplicado como solucao de acido silicico a 1 %, na dosagem equivalente a 3 t/ha de SiO 2 . Avaliaram-se os seguintes parâmetros biologicos: mortalidade larval, duracao da fase larval e pupal, viabilidade de pupa, peso das pupas, razao sexual, longevidade dos adultos, machos e femeas e o numero de ovos/femea. Verificou-se que a aplicacao de silicio aumentou apenas a mortalidade de lagartas alimentadas com folhas da BRS Cedro, nao demonstrando nenhum efeito nas lagartas quando aplicado na BRS Verde. Alem disso, na cultivar BRS Cedro, em comparacao com a cultivar BRS Verde, houve menor peso de pupa e menor producao de ovos/femea. Biology of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) in Colored Cotton Treated with Silicon Abstract. The caterpillar Spodoptera frugiperda (Smith) is a key pest of the corn culture and each year its occurrence in the cotton culture has increased, causing severe damage from the seedling phase to maturation. The objective of this work was to evaluate the effect of the silicon on the biology of S. frugiperda in white and colored fiber cotton plants. The bioassays were conducted with two cultivars of cotton, BRS Cedro (white fibers) and BRS Verde (green fibers), with and without silicon application. The silicon was applied as a solution of 1% silicon acid, at a dosage equivalent to 3 ton/ha of SiO 2 . The following biological parameters were evaluated: larval mortality, duration of the larval and pupal phase, pupal viability, pupal weight, gender ratio, adult longevity of males and females and the number of eggs/female. It was verified that the silicon application only increased the mortality of caterpillars fed with BRS Cedro leaves, not demonstrating any effect on the caterpillars when applied on BRS Verde. Furthermore, the BRS Cedro cultivar, when compared to the BRS Verde cultivar, presented a lower pupal weight and a lower eggs/female production.
