Authors: Tobias Joseph D.
Published: June 2014

The field of pediatric pain management continues to evolve, with ongoing changes in our appreciation of the impact of pain on our fragile patients, a better understanding of how to assess pain, and refinements of the medications and techniques used to provide analgesia to patients with acute pain of various etiologies. The following article reviews the techniques for the assessment of pain, including various age-specific pain scoring systems. The pharmacological management of pain is discussed, including the use of agents that inhibit prostaglandin formation—nonsteroidal anti-inflammatory agents and acetaminophen—as well as the “weak opioids” that are commonly used when oral administration is feasible for the treatment of mild to moderate pain.[Pediatr Ann. 2014; 43(7):e163–e168.]

Authors: Kovach Christine R. , Woods Diana Lynn , Devine Elizabeth C. , Logan Brent R. , Raff Hershel
Published: June 2014

This article discusses the use of biobehavioral measures as outcomes for health care intervention studies. Effect size (ES) values for salivary cortisol and observation-based measures of pain and agitation were examined. Effects pre to post treatment were assessed separately for nursing home residents with and without acute psychotic symptoms. This study revealed large positive effects on both pain and agitation measures in the group with acute psychotic symptoms and small-to-medium positive effects on these same measures in the group without acute psychotic symptoms. In both of these groups, the ES values were not consistently positive on the cortisol measures. Prior to determining whether a measure can be used to estimate minimum clinically important differences, it is essential to consider if the biomarker will be responsive to therapy in the populations and contexts being studied.

Published: June 2014

A novel tunable stiffness and damping vibration isolator based on magnetorheological nanocomposites filled with carbon nanotubes (CNMRE) was proposed. The stiffness and damping is controlled by the current applied to the magnetic excitation coil. Under the combined ON–OFF control law, the proposed vibration isolator shows satisfying isolation effect. The simulation results indicate that, in comparison to MRE isolator with ON–OFF stiffness and damping control, CNMRE isolator with ON–OFF control not only has high stiffness and damping capacity, corrosion resistance, and high failure strength which are demanded in industries, but also significantly suppresses vibration under sinusoid excitation, random excitation, and pulse excitation.

A Contribution to the Performance Estimation of Observability with a Thermal Camera, under Real Conditions of Vibrations and Visibility
Authors: Borcan Octavia
Published: June 2014

Most often observation with a thermal camera is not static; the platform on which the surveillance equipment is mounted is affected both by motor vehicle exterior vibrations and amplitudes of the movement in field. In this paper a case study is shown starting from some tests made on a moving boat and a visual method to analyze the motion is presented. Some images acquired in real time are fast and automatic analyzed using NIVision software to quantify the random and the sinusoidal motion made by the motor vibrations and the motion of the platform. Due to this phenomenon the images seems to be blurred but this blurring can be anticipated and avoided through a proper design of platform stabilisation if the motion parameters are known.

Self-Calibration of XY-Stage with Parallel Mechanism
Authors: Furutani Ryoshu , Yokouchi Satoshi , Ozaki Miyu
Published: June 2014

It is important to calibrate the straightness and the squareness of the XY-stage for precision manufacturing and measurement. Normally it is calibrated using much higher precise and accurate measuring instruments and/or artifacts. The high precision and accurate instruments and artifacts are expensive. So, in this paper, Self-calibration method is applied to XY-stage. This method does not require any much high precision and accurate instruments and artifacts. The normal XY-stage moves to the location at the unique coordinates. In this case, it is difficult to apply self-calibration method. Therefore, XY-stage is expanded to XYθ-stage with parallel mechanism. As this stage moves to the location at a lot of coordinates, self-calibration method is applied. This method is confirmed in simulation and experiment. In simulation, the extension lengths of mechanism are estimated from known kinematic parameters and the target coordinates. After that, estimated kinematic parameters are calculated by least-squares method from the extension lengths and the target coordinates. Finally, the positioning coordinates are calculated from the estimated kinematic parameters and the extension lengths. It is proved that the calibration method is effective by comparing the target coordinates and the positioning coordinates. In experiment, the experimental process is similar to the simulation without the estimation of extension lengths. The results of simulation and experiment are shown in this paper.

Authors: Lin Cherng Shing , Chou Kuo Da , Yu Chia Chun
Published: June 2014

Based on the European New Car Assessment Program, which offers rigorous testing conditions, this study developed a numerical model for the computer simulation of crash analysis and analyzed two crash situations: a high-speed vehicle crashing into a wall and a high-speed test vehicle crashing into a static vehicle. The Simulation model was constructed using the superior functions of the Patran software, and the Pam-crash software was employed to perform various calculations for analysis. In crashes, the structure of vehicle bodies are greatly compressed and deformed because of high-speed impact force, which simultaneously generates high speed acceleration. Vehicle structural deformation constricts the driver and passengers, and acceleration can cause them physical harm. Thus, the objective of this study was to identify the sources of harm to driver and passengers when crashes occur. The research results can be a reference for vehicle manufacturers in future vehicle development and a reference for future academic research.

Published: June 2014

In this study, experiments were performed to study the effects of electrode materials mixed with nickel in electrical discharge machining (EDM) of SUS 304 material. Experiments were constructed using parameters consisting of pulse-on time, pulse-off time, discharge current and electrode polarity, respectively. The analysis of structural features of the surface was accomplished using a scanning electron microscope (SEM) as well as an element analysis created on the surface, after the EDM process, by using Energy-dispersive x-ray spectroscopy (EDS). The results of the experiments found that nickel elements in the electrode material have an effect on the working performance of material removal rate and electrode wear ratio. The electrode wear ratio reduces when nickel elements increase. Moreover, the surface roughness had the lowest level at electrode 15 % nickel element. Thus, electrode wear during the EDM process of nickel element from electrodes and other elements, combined with surface metalworking, becomes a recast layer of nickel.

Published: June 2014

A two-run genetic programming (GP) is proposed to estimate the slump flow of high-performance concrete (HPC) using several significant concrete ingredients in this study. GP optimizes functions and their associated coefficients simultaneously and is suitable to automatically discover relationships between nonlinear systems. Basic-GP usually suffers from premature convergence, which cannot acquire satisfying solutions and show satisfied performance only on low dimensional problems. Therefore it was improved by an automatically incremental procedure to improve the search ability and avoid local optimum. The results demonstrated that two-run GP generates an accurate formula through and has 7.5 % improvement on root mean squared error (RMSE) for predicting the slump flow of HPC than Basic-GP.

The present work is concerned with the rolling motion of the battery pack when EV travelling on the road. First McPherson suspension system was regarded as the research object with detailed analysis of its structural features and motion characteristics. Establish the mathematical model which could apply to calculating the rolling motion of the vehicle body. Through MATLAB/Simulink simulation software, we could calculate the rolling angle on passive suspension. On this basis, assume that the battery pack mounted on the vehicle body and make it passive connection and PID connection. When the body rolls, the battery pack will produce a certain angle then. Next establish the mathematical model to summarize the relationship between the two variables. Then we set the parameters and calculate the roll angle of battery pack in both cases for comparison. Simulation results show that road irregularities will make battery rotate an angle and PID controller can effectively reduce the angle, especially angular acceleration. This paper put forward a new idea that battery is connected with body by active control on EV, and proves the superiority in reducing the rolling angle.

Published: June 2014

Faster and more accurate optical aspheric testing methods are required in many technical fields. A digital moiré phase shifting interferometer (DMPSI) with partial compensation lens (PCL) is proposed. With digital phase shifting technique, only one shot of interferogram is required, so the system structure is simpler with lower sensitivity to the environmental vibration. PCL is designed to enlarge the measurement range of asphericity. A DMPSI prototype in Fizeau configuration has been developed. After calibration, spherical surface is tested with accuracy comparable to Zygo interferometer.

Authors: Liang Ping , Zhang Yu Hang , Wei Jun , Yu Bing
Published: June 2014

Based on the weighted inverse topological change method and by introducing a new concept of mass submembers, a dynamical system can be transformed into a static one. Using the properties of the weighted D value, i.e. the weighted D value decreases monotonously with parameter λ increasing; a new method called the weighted D value iteration method is presented for computing the eigenpairs (eigenvalues and eigenvectors). Using this method a series of eigenpairs of a finite element structure can be obtained. It has a merit of simpler algorithm and less computation efforts. Not as the power method, its stability and convergence rate does not depend on the distribution of eigenvalues, and convergent quickly. An example is given to demonstrate the valid of this method.

Authors: Zhang Qian , Yang Yi Ping , Jiang Xin Wei
Published: June 2014

It is important to take account into both the spectral domain and spatial domain information for hyperspectral image analysis. Thus, how to effectively integrate both spectral and spatial information confronts us. Motived by the least square form of PCA, we extend it to a low-rank matrix approximation form for multi-feature dimensionality redu-ction. In addition, we use the ensemble manifold regularize-ation techniques to capture the complementary information provided by spectral-spatial features of hyperspectral image. Experimental results on public hyperspectral data set demonstrate the effectiveness of our proposed method.
