Current Controversies of Alignment in Total Knee Replacements
Authors: Donaldson James , Joyner James , Tudor Francois
Published: October 2015

Total knee replacement is an increasingly popular operation for end stage knee arthritis. In the majority it alleviates pain and improves function. However up to 20% of patients remain dissatisfied, even with well-aligned and secure implants.

Restoration of a neutral mechanical axis has traditionally been strived for, to improve both function and implant survival and there is historical data to support this. More recently this view has been questioned and some surgeons are trying to improve the function and outcomes by moving away from standard alignment principles in an attempt to reproduce the kinematics of the pre-arthritic knee of that individual. Others are using computers, robots and patient specific guides to improve accuracy. This article aims to review the traditional alignment concept and the newer techniques, along with the evidence behind it.
The Design of the Acoustic Isolator Used in Acoustic Telemetry While
Drilling
Authors: Haiming Xie , Jing Zhou , Feng Zhang
Published: October 2015

The acoustic isolator between the drilling bit and the acoustic piezoelectric transducer can attenuate the drilling
noise transmitted through the drill collar to avoid interference with the transmission of acoustic signals while drilling, and
also can be used to weaken the influence of downlink acoustic signal with the uplink channel produced by the transducer.
This paper improves the characteristic analysis of tapered acoustic transmission model, and the size and structure of the
acoustic isolator has been designed which has the characteristic frequencies of 700~800Hz and 1200~1300Hz.
Prediction on Carbon Emissions Reduction and Analysis on Economic Development Based on Energy Consumption Policy
Authors: Chen Hailong
Published: October 2015

As to the global warming, China has confidence in the development of the economy by bearing responsibility
and obligation toward curbing global warming, which at this time can be achieved by reducing carbon emissions. Industry
is an important material production department in the national economy, and plays a leading role in the national economy.
Chinese industrial production is mainly based on the consumption of fossil fuels, resulting in a large amount of CO2
emission. Therefore, how to find a way to predict the discharge of CO2 by computer technology and make people realize
the importance of low carbon development at industrial level is the focus of this study.

Published: October 2015

Public access to case law is a required prerequisite for the legal certainty
and the rule of law. Nevertheless, according to the law, only authorized
persons can access judgments in their non-anonymized and unredacted form.
This paper proposes a computer aided method for anonymization and redaction
of judgments, with an aim to improve efficiency of overall process. The
anonymization and redaction procedure is based on the access control
mechanism for XML documents. AKOMA NTOSO is chosen as an XML format in order
to facilitate integration with other (legal) information systems, but the
proposed method can be easily adapted to different document types and
different XML formats. The method is verified by a prototype implementation
which is validated by employees in a court of law.
Efficient processing of continuous queries utilizing F-relationship in stock databases
Authors: Park Sanghyun , Ha You-Min , Park Chihyun , Kim Sang-Wook
Published: October 2015

This paper analyzes the properties of user queries in a system for stock
investment recommendation, and defines the F-relationship, which is a new
type of a relationship between two queries. A query is composed of user
defined conditions for an interesting stock item and is systematically
invoked whenever the price of that stock item is changed. An F-relationship
between two queries Q1 and Q2 means that, if the recommendation type of a
preceding query Q1 is X, then its following query Q2 always has X as its
recommendation type, where the recommendation type is one of SELL, HOLD, BUY,
and NONE. If there is an F-relationship between Q1 and Q2, the recommendation
type of Q2 is decided immediately by that of Q1, therefore we can keep Q2
from being actually processed. To exploit this fact, we suggest two methods
in this paper. The former analyzes all the F-relationships among user queries
in the system and represents them as a graph. The latter searches the graph
and decides the order of queries to be processed, which makes the number of
unexecuted queries maximized. With these methods, a large portion of user
queries are not actually processed. As a result, the performance of
processing all the queries is greatly improved. We examined the superiority
of the suggested methods through a variety of experiments using real-world
stock market data. According to the results of our experiments, the overall
time of continuous query processing with our proposed methods has reduced to
less than 10% of that with the traditional method.
Packet dispersion strategy evaluation from the perspective of packet loss pattern and VoIP quality
Authors: Ninkovic Nemanja , Gajin Slavko , Reljin Irini
Published: October 2015

The appearance of burst packet losses and its devastating effect on Voice
over IP (VoIP) service have imposed a requirement for the implementation of
loss recovery mechanisms to address VoIP quality during periods when high
packet loss is exhibited. Existing loss recovery mechanisms are dependent on
end point capabilities, whereas Quality of service (QoS) routing protocols
suffer from complexity and scalability issues. In this paper, we examine
packet dispersion?s ability to address burst losses and provide a
computational model, which is verified using real network testing. A study
has been carried out to investigate the effect of different packet dispersion
strategies on burst losses, which clearly shows dispersion?s qualitative
superiority over single path routing. Furthermore, an analytical approach is
proposed resulting in quality estimation obtained by individual strategies.
Practical evaluation has shown that each strategy copes differently with
various burst scenarios in order to maximize VoIP quality.

Engine Variable Impact Analysis of Fuel Use and Emissions for Heavy-Duty Diesel Maintenance Equipment
Authors: Lewis Phil , Fitriani Heni , Arocho Ingrid
Published: October 2015

Heavy-duty diesel maintenance equipment consumes significant amounts of fuel and consequently emits substantial quantities of pollutants. The purpose of this study was to identify which engine activity variables had the greatest impact on fuel use and emissions rates. A real-world data set was used for a case study fleet containing backhoes, motor graders, and wheel loaders. Multiple linear regression was used to assess the relationships between engine activity variables and fuel use and emissions rates. The engine activity variables of engine speed, manifold absolute pressure, and intake air temperature were used to predict mass per time fuel use and emissions rates of nitrogen oxides, hydrocarbons, carbon monoxide, carbon dioxide, and particulate matter. The results indicated that manifold absolute pressure had the greatest impact on fuel use and emissions rate predictions. Based on this finding, fuel use and emissions estimating models based on manifold absolute pressure were developed as a practical estimating tool for practitioners.
Correlating the Safety Performance of Urban Arterials with Lighting
Authors: Zhao Jiguang , Zhou Huaguo , Hsu Peter
Published: October 2015

This paper presents a new method to evaluate roadway lighting performance at the corridor level based on the illuminance data collected by a mobile lighting measurement system. The illuminance data were collected at 40 ft (12 m) intervals on the outside and inside lanes for both directions of the roadway. Statistical analysis results indicate that the illuminance data at the corridor level fit the lognormal distribution. Two parameters, the mean and the variance of the illuminance, could be used to evaluate the lighting system at the corridor level by comparing the parameters for the roadway lighting systems with those for the design standard. In addition, the daytime and nighttime crash rates for the study corridors were calculated. The results indicate that the illuminance parameters are significantly related with the difference between daytime and nighttime crash rates; this factor further justifies the reasonableness of the new lighting evaluation method. The proposed method is recommended for evaluating lighting systems at the corridor level when the data are collected with the new mobile lighting measurement system.
Effects of Traffic Control Devices on Rural Curve Driving Behavior
Authors: Montella Alfonso , Galante Francesco , Mauriello Filomena , Pariota Luigi
Published: October 2015

This study investigated, by means of a dynamic driving simulator experiment, driver behavior at curves on rural two-lane highways in relation to different advance warning signs, perceptual measures, and delineation treatments. The tested treatments were intended to alert drivers to the presence of low-radius curves and to affect their behavior in the approach to the curve as well as along the curve itself. The study results showed that the advance warning signs, perceptual measures, and delineation treatments tested in the driving simulator experiment produced significant effects on driver behavior. The perceptual treatments (i.e., colored transverse strips, dragon teeth markings, colored median island) were the most effective treatments because they produced significant speed reductions in the approach tangent as well as inside the curve. Deceleration behavior in the approach to the curve was affected significantly by the presence of treatments that helped drivers to detect the curve earlier; early detection provided more time to perform deceleration maneuvers at lower rates. The study results strongly supported the real-world implementation of colored transverse strips, dragon teeth markings, and the colored median island. Implementation of the tested measures should be conducted on similar rural highways to validate general application of the results of this study to other regions.
Green Shared Lane Markings on Urban Arterial in Oakland, California
Authors: Foletta Nicole , Nielson Carrie , Patton Jason , Parks Jamie , Rees Robert
Published: October 2015

In 2013, the City of Oakland, California, implemented a green shared lane (i.e., super sharrow) treatment, which consisted of a continuous band of green color on the pavement in conjunction with shared lane markings (i.e., sharrows) as an experimental traffic control device. The implementation was an attempt to improve traffic operations on a multilane urban roadway frequented by cyclists but for which geometric constraints prevented installation of dedicated bicycle lanes. The purpose of the experiment was to promote ( a) safe and legal lane positioning by cyclists and ( b) safe and legal passing by motorists. Through statistical analysis, the effects of the green band (i.e., green shared lane) on user behavior were isolated for comparison with the effects of no bikeway striping and standard sharrows. The key findings were ( a) the green shared lane led cyclists to ride farther from parked cars (i.e., outside of the door zone) than they did with standard sharrows; ( b) standard sharrows and the green sharrow lane led motorists to shift more often from the right to the left travel lane than they did with no bikeway striping; ( c) the average passing distance for motorists who overtook cyclists did not change significantly; ( d) the percentage of motorists who left 3 ft or more when they passed decreased with the presence of the green sharrow lane; and ( e) the green shared lane had no negative operational effect on auto operations, auto speed, or transit speed.

OBJECT

Superior cluneal nerve (SCN) entrapment neuropathy (SCNEN) is a cause of low-back pain (LBP) that can be misdiagnosed as a lumbar spine disorder. The clinical features and etiology of LBP remain poorly understood. In this study, 5 patients with intermittent LBP due to SCNEN who had previously received conservative treatment underwent surgery. The findings are reported and the etiology of LBP is discussed to determine whether it is attributable to SCNEN.

METHODS

Intermittent LBP is defined as a clinical condition in which pain is induced by standing or walking but is absent at rest. Between April 2012 and March 2013, 5 patients in this study who had intermittent LBP due to SCNEN underwent surgery. The patients included 3 men and 2 women, with a mean age of 66 years. The affected side was unilateral in 2 patients and bilateral in 3 (total sites, 8). The interval from symptom onset to treatment averaged 51.4 months; the mean postoperative follow-up period was 17.6 months. The clinical outcomes were assessed using the numerical rating scale (NRS) for LBP, the Japanese Orthopaedic Association (JOA) scale, and the Roland-Morris Disability Questionnaire (RDQ) preoperatively and at the last follow-up; these data were analyzed statistically.

RESULTS

None of the 5 patients reported LBP at rest. Intermittent LBP involving the iliac crest and buttocks was induced by standing or walking an average of 136 m. In 2 patients with unilateral involvement, LBP was improved only by SCN block. Surgeries were performed on 6 sites in 5 patients because the SCN block was only transiently effective. Patients’ SCNs penetrated the orifice of the thoracolumbar fascia. SCN kinking at the orifice was exacerbated at the lumbar-extension provocation posture, and radiating pain increased upon manual intraoperative compression of the SCN in this posture. After releasing the SCN surgically, disappearance of the pain was intraoperatively confirmed by manual compression of the SCN with the patients in the lumbar-extension posture. Surgery was effective in all 5 patients, and all clinical outcome scores indicated significant improvement (p < 0.05).

CONCLUSIONS

To the authors’ knowledge, this is the first report of patients with intermittent LBP due to SCNEN. Clinical and surgical evidence presented suggests that their LBP was exacerbated by lumbar extension and that symptom relief was obtained by SCN block or surgical release of the SCN entrapment. These results suggest that SCNEN should be considered as a causal factor in patients for whom walking elicits LBP.

Bronze Age Kfar Monash. Palestine – A Chemical and Lead Isotope Study into the Provenance of its Copper
Authors: Hauptmann Andreas , Schmitt-Strecker Sigrid , Begemann Friedrich
Published: October 2015

Les objets de cuivre du trésor de Kfar Monash (EB I/ II de Palestine) sont faits de deux types de métaux. Des herminettes, une pointe de lance et un long couteau recourbé sont composés d’un cuivre arsénique, riche en nickel, contenant entre 0,4 et 3,88 % d’arsenic et un rapport moyen de As/ Ni de 1.4. Les autres outils et armes, mais aussi les fi nes et énigmatiques feuilles métalliques, (épaisses d’environ 0,5 mm) sont en cuivre pur. La même partition se retrouve dans l’isotopie du plomb : la proportion du 206Pb pour les objets de cuivre riche en As/ Ni forme un cluster de 208Pb/ 206Pb≈ 2.061, 207Pb/ 206Pb≈ 0.829 et 204Pb/ 206Pb≈ 0.0528 ; en revanche, les objets en cuivre pur montrent une grande variation dans les proportions les plus élevées ; ainsi, par exemple le rapport 208Pb/ 206Pb

varie entre 2,09 et 2,12. Concernant le cuivre riche en AsNi, les éléments traces et l’isotopie du plomb suggèrent que la source d’origine serait située au nord (Anatolie orientale) mais actuellement aucun gisement précis n’a été reconnu. Pour le cuivre pur, les sources possibles sont nombreuses dans le wadi Faynan et dans le sud du Sinaï. En l’absence de marqueurs spécifi ques, les données ne permettent pas d’identifi er une source du minerai. L’identifi cation des sources potentielles de ce minerai ne révèle aucune information sur le lieu de fabrication des objets. Les affi nités culturelles des objets de Kfar Monash avec l’Égypte et la Nubie ne peuvent donc être ni confi rmées ni infi rmées par les données matérielles présentées ici.

INTEGRATION OF EXPONENTIAL SMOOTHING WITH STATE SPACE FORMULATION FOR BUS TRAVEL TIME AND ARRIVAL TIME PREDICTION
Authors: Kumar Selvaraj Vasantha , Dogiparthi Krishna Chaitanya , Vanajakshi Lelitha , Subramanian Shankar Coimbatore
Published: October 2015

In recent years, the problem of bus travel time prediction is becoming more important for applications such as informing passengers regarding the expected bus arrival time in order to make public transit more attractive to the urban commuters. One of the popular techniques reported for such prediction is the use of time series analysis. Most of the studies on the application of time series techniques for bus arrival time prediction used Box-Jenkins AutoRegressive Integrated Moving Average (ARIMA) models, which are presently not suited for real time implementation. This is mainly due to the necessity and dependence of ARIMA models on a time series modelling software to execute. Moreover, the ARIMA model building process is time consuming, making it difficult to use for real-time implementations. Alternatively, Exponential Smoothing (ES) methods can be used, as they are easy to understand and implement when compared to ARIMA models. The present study is an attempt in this direction, where the basic equation of ES is used, as the state equation with Kalman filtering to recursively update the travel time estimate as the new observation becomes available. The proposed algorithm of state space formulation of ES with Kalman filtering for bus travel time and arrival time prediction was field tested using 105 actual bus trips data along a particular bus route from Chennai, India. The results are promising and a comparison of the proposed algorithm with ES alone without state space formulation and Kalman filtering has also been performed. An information system based on a webpage for real-time display of bus arrival times has been designed and developed using the proposed algorithm.
Enfants et adolescents en danger dans la rue : quel diagnostic ? Quelles préconisations ?
Authors: Douville Olivier
Published: October 2015

Définir les conditions d’un possible accompagnement médical et psychologique des mineurs en danger dans la rue suppose de prendre appui sur une clinique des circuits la parole, sur une observation des montages entre lieu et corps, et nécessite un travail préalable d’exploration des terrains dans une logique qui est celle de l’anthropologie de la cité. Nous refusons en ce sens toute lecture ethnopsychiatrique ou culturaliste de ce phénomène moderne et tentons de répondre à la question suivante : quelle vie psychique se met en péril mais se reprend aussi dans ces conduites d’errance extrême que nous allons ici présenter et étudier. Nous proposons alors la notion de « suradaptation paradoxale » qui rend compte de ces montages qu’opèrent les jeunes dans la rue entre parole, corps et relation à autrui. L’auteur montre en quoi cette notion est opérante pour la prise en charge de ces sujets souvent rebelles et vulnérables.

Les enfants accueillis en urgence dans les foyers de l’Aide sociale à l’enfance ont subi, pour beaucoup, des traumatismes et notamment des discontinuités relationnelles graves. Ce qui est alors primordial dans le travail auprès d’eux, c’est de leur permettre de retrouver une certaine confiance dans leur environnement et de tisser un lien authentique et fiable. C’est un travail long, loin des échéances des ordonnances judiciaires et difficile à maintenir face à une réalité effractante. Cet article relate mon expérience professionnelle au sein de ces institutions, quel cadre spécifique j’ai pensé avec ces enfants, et comment la forme des entretiens proposés et les accompagnements lors les déplacements vers mon bureau avaient une fonction de holding.
Mieux comprendre les caractéristiques d’un monitoring électronique des performances acceptable par les salariés, à la lumière des théories de la justice organisationnelle
Authors: Ben Fekih Aissi Linda , Neveu Valérie
Published: October 2015

Le monitoring électronique des performances des salariés est aujourd’hui largement répandu dans les organisations avec pour ambition affichée d’améliorer les performances des individus et donc indirectement des organisations. Pourtant, des réactions de rejet et de comportements contreproductifs sont par ailleurs mises en valeur dans la littérature. Nous utilisons le cadre théorique de la justice organisationnelle pour étudier le rôle joué par les perceptions de la justice dans l’acceptation par les salariés du monitoring électronique des performances (MEP). Prenant appui sur 35 entretiens menés auprès de téléopérateurs français, nous mettons en évidence les caractéristiques d’un MEP favorisant les perceptions de justice de la part des salariés et par là une meilleure acceptabilité par ces derniers. Les résultats montrent ainsi notamment le rôle essentiel joué par le manager de proximité dans l’acceptation du MEP mis en place. Il apparaît alors que, sous certaines conditions, le MEP peut être considéré de manière positive par les salariés, comme une source d’apprentissage et de stimulation des performances.

L’observation du corps du bébé ne se fait pas sans le corps de la mère et celui du pédiatre. Tout est mouvement, et concerne même les affects et pensées. Ces derniers, lorsqu’ils sont figés, ne peuvent s’exprimer que par des signes physiques observés sur le corps de l’enfant. Ceux-ci peuvent être vus ou entendus : observés et analysés en tant que tels, ou questionnés d’une autre place. Ainsi, un sens peut être donné, et un lien est parfois possible entre ces symptômes, les émotions, affects du bébé, de la mère, du père, et les histoires familiales. Car le mouvement, c’est la vie.

La oficina salitrera Santa Laura, que es actualmente el lugar donde se mantiene la infraestructura industrial más completa del periodo del procesamiento del salitre, posee una Torre de Lixiviación que es considerada, por su singularidad, el ícono de la otrora industria salitrera en Chile. Esta impresionante estructura, construida casi en su totalidad con madera de Pino Oregón (Pseudotsuga menziesii) y elementos metálicos en sus uniones, sobrelleva desafortunadamente, después del cese del proceso de fabricación de salitre y yodo, el impacto de su pasado productivo y posteriores acciones antrópicasambientales producto de su abandono y falta de mantenimiento. El presente informe, que contemplo inspección básica, instrumental y análisis estructural, es un diagnóstico del estado actual de conservación del edificio. Los resultados obtenidos indican que los elementos que conforman la estructura, con algunas excepciones, se encuentran en buen estado y sin alteración de sus propiedades mecánicas. El análisis estructural determinó que el comportamiento de la planta es favorable, siendo capaz de soportar un evento sísmico de importancia.
Restoration Technique to Optimize Recovery Time for Efficient OSPF Network
Authors: Garg Pertik , Gupta Ashu
Published: October 2015

Some high speed IP networks, which involve interior gateway protocols, such as OSPF, are not capable of finding the new routes to bypass the effect like failure in time. At the point when the failure occurs the network must converge it before the traffic has the capacity to go to and from the network segment that caused a connection disconnect. The duration of the convergence period of these protocols vary from hundred of milliseconds to 10 seconds, which creates unsteadiness and results high packet loss rate. This issue may be determined by proposing an algorithm that can rapidly react to the topology change and reduce the convergence time by providing back up path which is already stored in routing table before the failover occurs.
Signal Processing
Authors: Ghai Deepika , Jain Neelu
Published: October 2015

Digital signal processing algorithms are recursive in nature. These algorithms are explained by iterative data-flow graphs where nodes represent computations and edges represent communications. For all data-flow graphs, time taken to achieve output from the applied input is referred as iteration bound. In this chapter, two algorithms are used for computing the iteration bound i.e. Longest Path Matrix (LPM) and Minimum Cycle Mean (MCM). The iteration bound of single-rate data-flow graph (SRDFG) can be determined by considering the Multi-rate data-flow graph (MRDFG) equivalent of the SRDFG. SRDFG contain more nodes and edges as compared to MRDFG. Reduction of nodes and edges in MRDFG is used for faster determination of the iteration bound.
Adoption of Dual Iris and Periocular Recognition for Human Identification
Authors: Deepika R. , Prasad M. R. , Chetana Srinivas , Manjunath T. C.
Published: October 2015

Personal identification from the iris images acquired under less-constrained imaging environment is highly challenging. Such environment requires the development of efficient iris segmentation approach and recognition strategy which can exploit multiple features available for the potential identification. So, along with the iris features periocular features have increasing attention in biometrics technology. For the recognition purpose iris and periocular information are collected from both the eyes of same person simultaneously. The term periocular refers to the facial region in the immediate vicinity of the eye. Acquisition of image for periocular biometric is expected to require less subject cooperation. In this chapter, a dual iris based multimodal biometric system that increases the performance and accuracy of the typical iris recognition system is proposed.

Published: October 2015

Synthetic Aperture Radar (SAR) are imaging Radar, it uses electromagnetic radiation to illuminate the scanned surface and produce high resolution images in all-weather condition, day and night. Interference of signals causes noise and degrades the quality of the image, it causes serious difficulty in analyzing the images. Speckle is multiplicative noise that inherently exist in SAR images. Artificial Neural Network (ANN) have the capability of learning and is gaining popularity in SAR image processing. Multi-Layer Perceptron (MLP) is a feed forward artificial neural network model that consists of an input layer, several hidden layers, and an output layer. We have simulated MLP with two hidden layer in Matlab. Speckle noises were added to the target SAR image and applied MLP for speckle noise reduction. It is found that speckle noise in SAR images can be reduced by using MLP. We have considered Log-sigmoid, Tan-Sigmoid and Linear Transfer Function for the hidden layers. The MLP network are trained using Gradient descent with momentum back propagation, Resilient back propagation and Levenberg-Marquardt back propagation and comparatively evaluated the performance.
Face Recognition using Fast Fourier Transform
Authors: Baragi Shivakumar , Iyer Nalini C.
Published: October 2015

Biometrics refers to metrics related to human characteristics and Traits. Face Recognition is the process of identification of a person by their facial image. It has been an active area of research for several decades, but still remains a challenging problem because of the complexity of the human face. The objective is to authenticate a person, to have a FAR and FRR very low. This project introduces a new approach for face recognition system using FFT algorithm. The database that contains the images is named as train database and the test image which is stored in test database is compared with the created train database. For further processing RGB data is converted into grayscale, thus reduces the matrix dimension. FFT is applied to the entire database and mean value of the images is computed and the same is repeated on test database also. Based on the threshold value of the test image, face recognition is done. Performance evaluation of Biometrics is done for normal image, skin color image, ageing image and blur image using False Acceptance Rate(FAR), False Rejection Rate(FRR), Equal Error Rate(EER) and also calculated the accuracy of different images.

Fuzzy Model for Middle Section of Continuous Line
Authors: Fedor Pavol , Perdukova Daniela
Published: October 2015

The paper presents a methodology for designing a fuzzy model for the middle section of a continuous processing line for tension processing of various materials (sheet metal, tubes, foil, etc.), which is only described by input/output relations. The measured input/output data of the continuous line are the basis for creating its fuzzy model, which can be further applied in the design of a suitable controller and the verification of its properties by simulation. The first part of the paper describes the procedure of the fuzzy model construction; the second part presents the application of the model in the system of the middle section of a continuous processing line. The fuzzy model structure is based on the state space representation of the dynamic system in discrete form. The properties of the fuzzy model were verified by numerical simulation in Matlab. The obtained results have confirmed the rightness of the design method and its applicability to dynamic systems with multiple inputs and outputs.

Published: October 2015

Due to its relatively low mass density, low cost, high strength, the aluminum alloy is an ideal optical material to fabricate the large metal mirror of infrared band optical systems. The diamond ultra-precision cutting can produce ultra smooth machined surfaces without other finishing processes. Consequently, it can be used as a effective method to fabricate the large metal mirror. However, the tool wear is severe during the ultra-precision processes, which will ruduces the surface error of the large metal mirror. In this work, the ultra-precision cutting tests were performed to investigate the tool wear. The tool wear was examined by using a scanning electron microscope (SEM), and the chip was examined by using x-ray energy dispersive spectrdmeter (EDS). The tool wear mechanism and the influence of the chutting parameters on the tool wear were investigated. The results show that the daimond tool occurred abrasive wear and diffusing wear in the diamond ultra-precision cutting of aluminum alloy. The average clearance wear width increases with an increase of the cutting speed and the feed rate. There is a slight rise in the average clearance wear width as the depth of the cut increases in the range of 5μm-15μm. The average clearance wear width obviously increases when the depth of the cut reaches to 20μm.

Authors: Yu Feng Qin , Wang Jun
Published: October 2015

Because of the non-uniformity of the section shape of rail and complexity of its temperature changing, the degree of thermal expansion and contraction of section must be different which leads to the interior stress is produced inevitable in it. The residual stress in rail is elastic stress and its maximum value is elastic limit stress. They affect the dimension stability, mechanical property, deformation and etc. And it is the important factor of rail quality. This paper builds a finite element model of temperature field through the MSC.Marc software during the process of heating and cooling of 55Q rail, which simulates the rail stress field of air cooling and water cooling. Our paper conducts the experiments on the rails of same material and condition and also selects the temperature and stress of appointed nodes to analyze them. The results of experiments and simulations are very identical. Simulating the residual stress of air cooling and water cooling, the result is that residual stress of water cooling is bigger than that of air cooling. This consequence gives the reference for planning the suitable heat treatment and improving the service life.

Published: October 2015

Jet electrodeposition is one of electrochemical machining methods, which is able to increase cathodic current density, therefore having high deposition rate, good locality and nanocrystalline structure. These advantages enable jet electro-deposition to integrate with rapid prototyping technology in an effort to achieve selective electro-deposition on the cathode surface. This paper combine both methods to prepare nanocrystalline copper parts. The equipment system is developed, which is mainly composed of computer control system, machine body, electrolyte circulation system, nozzle and its hoisting mechanism and other parts. Deposition rate, locality, deposit thickness distribution and forming accuracy are analyzed. A group of nanocrystalline copper parts having good shape and size precision have been prepared.

Basic Experiment of Ultrasonic Deep Rolling with Longitudinal-Torsional Vibration
Authors: Zheng Jian Xin , Hou Ya Li , Ming Ping Mei
Published: October 2015

Orthogonal experiments of ultrasonic deep rolling with Longitudinal-torsional vibration (UDR-LTV) and conventional deep rolling (CDR) Q235 steel were carried out to study the effects of processing parameters on surface roughness. The orthogonal experiments results show that the influence laws of processing parameters on surface roughness are the same, and the values of surface roughness obtained by UDR-LTV are smaller than that of CDR with the same processing parameters. The values of surface roughness obtained by UDR-LTV and CDR increase and then decrease with the increment of the static pressure; and increase with the increment of the feed-rate, and change a little along with the increment of the rolling speed. Meanwhile, the feed-rate has a marked effect on the surface roughness, while the rolling speed has a little effect on the surface roughness. The quadratic regression method is used to construct the mathematic model to predict surface roughness based on the experimental results. The effects of parameter interactions on surface roughness are studied. The research shows that the interaction effects of the rolling speed and the feed-rate, the static pressure and the feed-rate on surface roughness are obvious, but the interaction effect of the static pressure and the rolling speed on surface roughness is not significant. The optimal parameters for the lowest surface roughness are given by the result of orthogonal design and prediction model, which has guiding significance for the application of ultrasonic surface strengthening technology with complex vibration mode.
