Published: March 2017

Shock absorbers are intended for developing forces providing the elimination or reduction of the amplitude of cars or their parts fluctuations. On the CIS railroads, the wedge-type shock absorber became the most wide-spread in trucks of freight cars. In friction shock absorbers, the friction force arises in vertical and horizontal movements of the absorber wedges rubbing on friction plates fixed on the columns of the truck sidewalls. In the article, the modeling of dynamic characteristics of a freight car with the optimized parameters of the wedge-type shock absorber is performed. The modeling is performed by means of the software complex for studying the problems of dynamics of rail vehicles: “The universal mechanism”. A dynamic and block diagram of the dynamic model of the car platform, as well as of the mathematical model for studying the friction force and interaction of contact power elements, accounting the creep forces in contact by means of the FASTSIM algorithm based on the Kalker linear theory, is developed. The obtained results of modeling of an eight-wheel freight car with modernized frictional wedges show that in the truck modernization it is expedient to provide additional devices, for example a frictional shock absorber in the central step of suspension. The results of the carried out study prove the expediency of using for the upgraded truck of 18-100 model the design of M1816.06.000 SB, M1819.00.000 SB wedges, at this it is recommended to accept rigidity of elastic elements of these wedges equal to 1.1 kN/mm that is a compromise solution for the safe car movement in the empty and loaded modes.
An improved state space method for force identification based on function interpolation in the presence of large noise
Authors: Wang Ting , Wan Zhimin , Zheng Weiguang
Published: March 2017

The conventional state space method for force identification has the disadvantage of large discretization error with a low sampling frequency. This paper presents an improved method based on the function interpolation of the external force in time domain. Two types of the interpolation functions are investigated, one is the linear interpolation, and the other type is the sigmoid curve interpolation. Gauss integration method is used for integration computation. Numerical studies show that both of the improved methods based on the two types of interpolation function are more accurate especially when the sampling is long and/or with a low sampling frequency. In addition, the proposed method is also extended for the case of high noise level. The key idea is to divide the time step of measured responses into several smaller time steps to form an overdetermined equation of the inverse force identification. Then, the least square algorithm is adopted, which helps to reduce the effect of the high random noise to improve the accuracy of identified solution.

Authors: Chang Yonggen , Jiang Fan , Zhu Zhencai , Li Wei
Published: March 2017

In order to raise the working reliability of rotating machinery in real applications and reduce the loss caused by unintended breakdowns, a new method based on improved ensemble empirical mode decomposition (EEMD) and envelope spectrum analysis is proposed for fault diagnosis in this paper. First, the collected vibration signals are decomposed into a series of intrinsic mode functions (IMFs) by the improved EEMD (IEEMD). Then, the envelope spectrums of the selected decompositions of IEEMD are analyzed to calculate the energy values within the frequency bands around speed and bearing fault characteristic frequencies (CDFs) as features for fault diagnosis based on support vector machine (SVM). Experiments are carried out to test the effectiveness of the proposed method. Experimental results show that the proposed method can effectively extract fault characteristics and accurately realize classification of bearing under normal, inner race fault, ball fault and outer race fault.
Research on transverse vibration characteristics of rope change device with clamping chain transmission in lifting system
Authors: Kou Baofu , Liu Qiuzu , Li Ning
Published: March 2017

In order to reduce load impact and hydraulic leakage happened in the process of locked rope switching or stroke arrival for the present rope changing devices, a novel type of rope changing device with clamping chain transmission is designed based on the “pipe forming mechanism”. The new device fundamentally improves the safety and stability of steel-rope. By theoretical deduction, the steel-rope transverse vibrations in rope changing of the new device are calculated. Results show that the compacting force of locked-rope mechanism can reduce the transverse vibration amplitude by 80 % or more, which is caused by the polygon effect in chain transmission; as the increasing rigidity of locking disc spring, the limitation for transverse vibration displacement of wire rope becomes stronger, and the effect is fading when the rigidity reaches a certain value. Transverse vibration trends of steel-rope from test are consistent with the theoretical calculation results, which verify the correctness of the theoretical calculation; The maximum vibration amplitude of steel-rope is less than 0.4mm, effectively limiting the transverse vibration caused by the polygon effect in chain transmission and making the steel-rope work continuously and smoothly.

Published: March 2017

French vertical flow constructed wetlands (VFCW) treating raw wastewater have been developed successfully over the last 30 years. Nevertheless, the two-stage VFCWs require a total filtration area of 2–2.5 m2/P.E. Therefore, implementing a one-stage system in which treatment performances reach standard requirements is of interest. Biho-Filter® is one of the solutions developed in France by Epur Nature. Biho-Filter® is a vertical flow system with an unsaturated layer at the top and a saturated layer at the bottom. The aim of this study was to assess this new configuration and to optimize its design and operating conditions. The hydraulic functioning and pollutant removal efficiency of three different Biho-Filter® plants commissioned between 2011 and 2012 were studied. Outlet concentrations of the most efficient Biho-Filter® configuration are 70 mg/L, 15 mg/L, 15 mg/L and 25 mg/L for chemical oxygen demand (COD), 5-day biological oxygen demand (BOD5), total suspended solids (TSS) and total Kjeldahl nitrogen (TKN), respectively. Up to 60% of total nitrogen is removed. Nitrification efficiency is mainly influenced by the height of the unsaturated zone and the recirculation rate. The optimum recirculation rate was found to be 100%. Denitrification in the saturated zone works at best with an influent COD/NO3-N ratio at the inflet of this zone larger than 2 and a hydraulic retention time longer than 0.75 days.

A Novel Multiscale Numerical Model for Prediction of Texture-Related Impacts on Fuel Consumption
Authors: Mansura Dmytro A. , Thom Nicholas H. , Beckedahl Hartmut J.
Published: March 2017

It is estimated that to overcome rolling resistance (RR) a typical vehicle, on average, consumes 4152 MJ/119 L of fuel annually, depending not only on vehicle-related factors but also on pavement-related factors. A slight improvement in surface properties may thus decrease fuel consumption, bringing substantial long-term socioeconomic benefits per capita per country. This aligns with ever-tighter limits on CO2 in the European Union (95 g/km until 2021), fostering sustainable construction and exploitation of tires and pavements. This paper outlines a newly developed multiscale three-dimensional numerical methodology to quantify texture-dependent RR due to indentation of aggregates into viscoelastic tread compound. It consists of a microscale tread block single-aggregate model and a macroscale car tire finite element model, rolling in a steady-state mode over a rigid smooth surface. Microscale interaction rates are deduced from the macroscale model. Tread compound is simulated by application of a time-dependent, linear, viscoelastic model. The microscale simulations enabled quantification of RR induced by an arrangement of surface aggregates. The outlined texture-dependent RR estimates are based on contact force moment around the contact patch center. The computed contact force results show a significant peak of normal force due to viscoelastic and inertia effects at the onset of the tire–surface contact phase, followed by a gradually decreasing/relaxing stress region with a sudden release at the end of the interaction. The contact forces seem to be of a reasonable distribution and magnitude. The proposed approach allows prediction of RR losses due to compressive forces at the microscale. Macro-distortional RR (which is not the subject of this paper) would then have to be added to find the total tire-related RR.

Se obtuvieron compuestos aligerados de matriz de yeso reforzados con cascarilla de arroz y partículas de poliestireno. Las muestras fueron caracterizadas por medio de análisis mecánico, y morfológico mediante microscopia electrónica de barrido (MEB) y espectroscopia de electrones dispersados (EDS). La zona interfacial entre la matriz de yeso y la fibra de cascarilla de arroz fue estudiada por medio de una prueba de arrancamiento y análisis microestructural. Los resultados obtenidos mostraron que las partículas de poliestireno permiten la obtención de materiales compuestos aligerados pero al mismo tiempo se comprometen las propiedades mecánicas de los mismos, lo que hace que el uso de estos materiales compuestos sea de tipo no estructural. Por otro lado, las fibras de cascarilla de arroz reforzaron la matriz de yeso incrementando significativamente las propiedades de flexo-tracción de la matriz de yeso y la tenacidad de los compuestos al mismo tiempo que disminuyeron la densidad de los mismos.

Influence of Rice Husk Ash Density on the Workability and Strength of Structural Concrete

Published: March 2017

Supplementary cementitious materials (SCMs) have been known to improve the properties of fresh and hardened concrete, and at the same time enhance the sustainability of concrete. Rice husk Ash (RHA), is one such material, but has neither been widely studied nor applied in practice. This work investigated the effect of the density of RHA on the workability and compressive strength of fresh and hardened RHA-replaced concrete respectively. Cement was replaced with RHA in concrete by weight (RHA-W) and by volume (RHA-V) at steps of 0%, 5%, 7.5%, 10%, 15%, 20%, 25% and 30%. The 0% replacement was used as the reference point from which performances were measured. Results showed that unlike the characteristic of other established pozzolans, RHA significantly reduced the workability of wet concrete and the rate of compressive strength gain over curing time due to a high water demand that is caused by the increased volume of replaced concrete, which results from its low density. Workability reduced with increased replacement for both RHA-W and RHA-V. Replacements of above 15% were not possible for the RHA-W due to the high water demand. However, replacements of up to 30% were achieved for the RHA-V. RHA-W specimens achieved lower compressive strengths and were observed to gain strength at a lower rate over the 28 to 91-days period of curing compared to RHA-V specimens. This behavior was attributed to the shortage of water that is necessary for the hydration of cement and subsequent pozzolanic reaction, which is the basis of the contribution that is made to the strength and performance of concrete by SCMs. However, the compressive strengths achieved were above the study’s target concrete strength of class C32/40 at 91 days, which is among those classes that are listed as being durable and suitable for structural applications. A conclusion that RHA should supplement cements by volumetric replacement rather than simple substitution by weight was drawn.
Renforcement des données probantes et des mesures relatives aux partenariats plurisectoriels en santé publique : un projet de
recherche-action
Authors: Willis C. D. , Greene J. K. , Abramowicz A. , Riley B. L.
Published: March 2017

Introduction

L’initiative Partenariats plurisectoriels de l’Agence de la santé publique du Canada, gérée par le Centre de prévention et de contrôle des maladies chroniques (CPCMC),
réunit différents partenaires en vue de concevoir, de mettre en oeuvre et de faire progresser des approches novatrices visant à améliorer la santé de la population.
Cet article décrit l’évolution et les premières priorités d’un projet de recherche-action (stratégie d’apprentissage et d’amélioration) dont l’objectif est de faciliter l’amélioration continue
de l’initiative de partenariat du CPCMC et de contribuer aux données probantes sur les partenariats plurisectoriels.

Méthodologie

La stratégie d’apprentissage et d’amélioration du CPCMC pour les partenariats plurisectoriels repose sur les consultations avec le personnel et la haute direction du CPCMC
et sur l’examen de cadres conceptuels liés aux partenariats plurisectoriels. Les consultations ont porté sur l’élaboration de l’initiative plurisectorielle, ses obstacles, ses facteurs de réussite et ses indicateurs d’efficacité. Nous avons fait une revue de littérature
et consulté la littérature grise en appliquant une stratégie de recherche systématique puis nous avons résumé nos conclusions sous forme de comptes rendus.

Résultats

Les consultations et l’examen de la littérature ont souligné l’importance de comprendre l’incidence des partenariats, d’élaborer une vision commune, de mettre en
oeuvre un système partagé de mesures et de créer des occasions d’échange de connaissances. C’est dans cette perspective que nous proposons une stratégie d’apprentissage
et d’amélioration en six volets : 1) donner la priorité aux besoins en matière d’apprentissage, 2) relier les besoins aux données probantes, 3) utiliser des méthodes de
collecte de données pertinentes, 4) analyser et synthétiser ces données, 5) fournir une rétroaction aux membres et aux équipes du CPCMC et 6) agir.
Les premiers besoins en matière d’apprentissage concernent la portée des partenariats et les répercussions non anticipées des partenariats plurisectoriels
sur les individus, les équipes, les organismes et les communautés.

Conclusion

Bien que principalement destinée au CPCMC, la stratégie d’apprentissage et d’amélioration pourrait s’avérer tout aussi pertinente pour d’autres publics, notamment
d’autres ministères ou organismes externes intéressées à saisir et partager de nouvelles connaissances sur les partenariats plurisectoriels.

Through his paintings, Earle offers one of the first comprehensive European artistic impressions of parts of New Zealand and its inhabitants prior to the onset of large-scale British colonisation. Many of his conclusions and perspectives were unavoidably subjective, but they at least offer a glimpse into one person’s impression of the country at this time.
What's in a word
Authors: Hata Sandy
Published: March 2017

Language is the cornerstone of communication and can be conveyed in many forms.  One such form is composition or song.  There are many indigenous compositions that provide a backdrop reflecting the landscape, events and relationships that were integral to and impacted on the life of the composer and their communities.

As a research subject, compositions from the early nineteenth century provide a template with which to analyse the language used and its relevance in today’s environment.  Written languages change with the introduction of new technologies and environments. Compositions such as laments have stayed intact as part of an oral tradition.  This research aims to examine whether the written history and poetic prose of the words within compositions has also stayed intact and been maintained. Specific words will be analysed in relation to their usage within both a traditional and modern context.

Igniting the spark: How to achieve collective ownership of a tribal language revitalisation strategy
Authors: O'Regan Hana
Published: March 2017

The Kāi Tahu tribal language Strategy, Kotahi Mano Kāika, Kotahi Mano Wawata – A thousand homes, a thousand dreams, is now in its 11th year and has recently been internally reviewed.  As a tribe we remain in the position of a people whose language is in the worse state of all tribes in New Zealand and we are far from achieving a level of sustainability in our efforts.

The greatest challenge we have faced and continue to face, is the engagement of the majority of our kin who are non-language speakers in our revitalisation effort, and this includes a significant proportion of our tribal governance.  As the language continues to take 2nd place to the wider social and political issues facing the tribal collective, the task of revitalisation becomes increasingly challenging and esperate.

This paper will discuss the strategies that have been used over the past 10 years to achieve collective ownership of our language revitailstion effort and will look the challenges ahead of us as a tribe and as language communities to achieve language sustainability for our people and future generations.
Implementation of modified AQM mechanisms in IP routers

The article is an attempt to answer the question if it makes sense to modify the way of choosing packets to reject inAQM mechanisms. Simulation and analytical research of RED and DSRED mechanisms shows that their efficiency grows when packet is received from the front of the queue. It is especially conspicuous when taking into account the self-similarity of traffic. However implementation of the above mentioned mechanisms in real router does not corroborate such a clear advantage over Drop-From-Front strategy. In this article the results of analytical, simulation and real router research based on the Linux operating system have been presented.
