Data mining for average images in a digital hand atlas

Bone age assessment is a procedure performed in pediatric patients to quickly evaluate parameters of maturation and growth from a left hand and wrist radiograph. Pietka and Cao have developed a Computer-aided diagnosis (CAD) method of bone age assessment based on a digital hand atlas. The aim of this paper is to extend their work by automatically select the best representative image from a group of normal children based on specific bony features that reflect skeletal maturity. The group can be of any ethnic origin and gender from one year to 18 year old in the digital atlas. This best representative image is defined as the "average" image of the group that can be augmented to Piekta and Cao's method to facilitate in the bone age assessment process.
Evaluation of Cooling Technologies for Xeon Phi™ Based High Performance Computing Clusters

Efficient and compact cooling technologies play a pivotal role in determining the performance of high performance computing devices when used with highly parallel workloads in supercomputers. The present work deals with evaluation of different cooling technologies and elucidating their impact on the power, performance, and thermal management of Intel® Xeon Phi™ coprocessors. The scope of the study is to demonstrate enhanced cooling capabilities beyond today’s fan-driven air-cooling for use in high performance computing (HPC) technology, thereby improving the overall Performance per Watt in datacenters. The various cooling technologies evaluated for the present study include air-cooling, liquid-cooling and two-phase immersion-cooling. Air-cooling is evaluated by providing controlled airflow to a cluster of eight 300 W Xeon Phi coprocessors (7120P). For liquid-cooling, two different cold plate technologies are evaluated, viz, Formed tube cold pates and Microchannel based cold plates. Liquidcooling with water as working fluid, is evaluated on single Xeon Phi coprocessors, using inlet conditions in accordance with ASHRAE W2 and W3 class liquid cooled datacenter baselines. For immersion-cooling, a cluster of multiple Xeon Phi coprocessors is evaluated, with three different types of Integrated Heat Spreaders (IHS), viz., bare IHS, IHS with a Boiling Enhancement Coating (BEC) and IHS with BEC coated pin-fins. The entire cluster is immersed in a pool of Novec 649 (3M fluid, boiling point 49 °C at 1 atm), with polycarbonate spacers used to reduce the volume of fluid required, to achieve target fluid/power density of ∼ 3 L/kW. Flow visualization is performed to provide further insight into the boiling behavior during the immersion-cooling process.Performance per Watt of the Xeon Phi coprocessors is characterized as a function of the cooling technologies using several HPC workloads benchmark run at constant frequency, such as the Intel proprietary Power Thermal Utility (PTU), and industry standard HPC benchmarks LINPACK, DGEMM, SGEMM and STREAM. The major parameters measured by sensors on the coprocessor include total power to the coprocessor, CPU temperature, and memory temperature, while the calculated outputs of interest also include the performance per watt and equivalent thermal resistance. As expected, it is observed that both liquid and immersion cooling show improved performance per Watt and lower CPU temperature compared to air-cooling. In addition to elucidating the performance/watt improvement, this work reports on the relationship of cooling technologies on total power consumed by the Xeon-Phi card as a function of coolant inlet temperatures. Further, the paper discusses form-factor advantages to liquid and immersion cooling and compares technologies on a common platform. Finally, the paper concludes by discussing datacenter optimization for cooling in the context of leakage power control for Xeon-Phi coprocessors.Copyright © 2015 by ASME
Remote sensing of the sea-surface by dekametric radar

The evolution of the technique of remote sensing of the sea-surface by dekametric radar is traced from the original observation of the Bragg resonant scattering phenomenon by D. D. Crombie in 1955 to its present applications to the measurement of surface wind-direction and wind-speed, wave-height spectrum, wave-directional spectrum and surface-currents. The central role played by the Doppler spectrum of the radar echoes is illustrated. The generation and spectral properties of wind-driven waves on the sea-surface are discussed including wave-wave interactions and the nature of electromagnetic scattering by first and second-order processes is described.An account is given of the techniques used for UK experiments on ground-wave radar surveying the Celtic Sea from West Wales. Synthetic aperture experiments using a moving vehicle permitted the directional spectrum of the sea-surface to be determined. Sky-wave experiments from a radar in Southern England permitted comparisons with sea-state and surface winds measured in the Rockall Bank area of the North Atlantic by oceanographic vessels and buoys.Finally, work in progress in the US and UK on improved narrow beam and interferometer radars and new methods for inversion of measured Doppler spectra to yield seawave spectra are reviewed.
A new analytical control strategy for a magnetic suspension system under initial position dispersions

A nonlinear magnetic suspension system is considered in this paper. A novel online algorithm based on analytical approach is presented to stabilize the suspended mass. The new algorithm employs a single analytical function to create the ball position and velocity profiles. The reference ball position is described by a series of time dependent exponential functions. Boundary conditions at both initial and final states are automatically satisfied. Moreover, feasible ball position and velocity profiles are ensured by evaluating one algorithm parameter (an exponential factor). The exponential factor is analytically computed by minimizing the peak of electrical power. This new algorithm is capable of generating the well-suited coil voltage that guarantees the stability of the system with a small closed-loop command. Gain Shechting method is used to obtain the closed-loop effort in order to track the analytical reference profiles. Compared to the prior magnetic suspension algorithms, the proposed analytical scheme is qualified to handle very large dispersions in initial ball position while satisfying the ball position and coil voltage constraints. Monte-Carlo simulations with change in initial ball position are presented. The simulation results demonstrated the great reliable performance of the proposed algorithm despite the wide range of initial ball position dispersions.
Southern African Large Frame Indigenous Veld Goat and Boer Goat Wether and Buck Tenderness and Colour of Six Muscles

Meat tenderness, water holding capacity (WHC) and colour attributes of six muscles (Longissimus thoracis et lumborum (LTL), Semimembranosus (SM), Biceps femoris (BF), Supraspinatus (SS), Infraspinatus (IS), Semitendinosus (ST)) from large frame Indigenous Veld Goats (IVG) and Boer Goats (BG) were studied. Weaner male Boer Goats (BG; n = 18; 10 bucks and 8 wethers) and large frame Indigenous Veld Goats (IVG; n = 19; 9 bucks and 10 wethers) were raised on hay and natural grass, and on a commercial pelleted diet to a live weight of 30 - 35 kg. All goats were slaughtered at a commercial abattoir and the dressed carcasses chilled at 4°C within 1-hour post-mortem. The muscles were dissected from both sides 24-hours post-mortem and aged for 1-day and 4-days. Variations in meat characteristics such as ultimate pH, WHC, percentage purge, myofibril fragment length, intramuscular fat, connective tissue characteristics, and Warner-Bratzler shear force. Bucks had higher L* and Hue-angle values, whereas wethers had increased a* and Chroma values. The muscle baseline-data will allow informed decisions to support muscle-specific marketing strategies, which may be used to improve consumer acceptability of chevon.
Noise Characterization of Differential Multi-Element Multiport Networks - the Wave Approach

In this paper there is presented and discussed a general analysis method for noise characterization of noisy multi-element multiport differential networks. It is based on mixed mode, differential and common mode, noise waves representation of noise, generalized mixed-mode scattering parameters and generalized mixed-mode noise wave correlation parameters for the network. There are derived analytical relation between the noise figure for a given output port and the noise matrix and the scattering parameters of the network, as well as the correlations between the input port noise waves. The signal to noise ratio degradation factor is derived and discussed, too. Presented results can be implemented directly in a CAD software for noise analysis of differential microwave multi-element multiport networks with differential as well as with conventional single ended ports.
STATECHARTS TO SPECIFY THE CONTROL OF AUTOMATED MANUFACTURING SYSTEMS

This paper deals with the use of Statecharts formalism, a recent automata-based language, to specify the control of automated manufacturing systems (AMS). Statecharts has been developed for the description of complex reactive systems; it provides high level constructs that facilitate carrying out large problems by a graphical structured approach. The main features of the formalism are given in the introduction. A way to design the most important constructs and mechanisms of a control field is proposed. Then, these constructs are implemented in order to specify the control of a flexible manufacturing and to show the adequacy of Statecharts for AMSs. Other useful constructs are given making if possible to translate control specifications according to a structured analysis method. Generic specification is also presented and the graphical simplification they provide in case of generic behaviour handling is clarified. Extensions made to Statecharts support are also illustrated.
Development of a Tool to Measure the Effectiveness of Kaizen Events within the Wood Products Industry

Kaizen implementation and other continuous improvement practices can be used by companies to lower manufacturing costs and increase product value. Kaizen activities are one way that wood products companies can increase their competitiveness. Being able to measure the effectiveness of Kaizen events is important to factors that contribute to Kaizen’s effectiveness as well as identifying the success of Kaizen implementation. However, little research has focused on the implementation of Kaizen and other continuous improvement methods within the wood products industry or on the perceptions of employees within this industry regarding either the motivators for, barriers to, and effectiveness of perceptions of Kaizen, or the drivers affecting Kaizen implementation. The goal of this research is to develop a tool to measure the effectiveness of Kaizen and to apply this tool to companies within the wood products industry. To accomplish this research goal, a case study approach was used in examining how two U.S. wood products companies implemented Kaizen and other continuous improvement initiatives and how employees at these companies viewed such implementation. As part of this case study, interviews were conducted with staff in each company and surveys were administered to production and non-production employees at each company. A tool was developed to measure the perceived effectiveness of Kaizen events, and this tool was tested using the survey data were collected from each company. The results from these analyses show statistically significant differences in how production employees across companies viewed the following: motivators related to cost and quality
Fractional-Order PI Controller with Specific Gain–Phase Margin for MABP Control

ABSTRACT Mean arterial blood pressure (MABP) is one of the most important clinical parameters which is required to be controlled very accurately. Therefore, it is very essential to have an efficient and precise control strategy for regulating the MABP in various clinical conditions, which can work well in uncertain operating environment, and also show good disturbance rejection. Although the fractional-order control scheme has evolved as a strong control strategy in recent times, the design techniques available in the literature are mathematically very complex and hence limit the usage of fractional-order controllers. Moreover, it is observed that the gain and phase margin based techniques that exist in the literature for integer order systems are not completely applicable to the fractional-order systems. Therefore, in this paper, a design scheme is proposed for fractional-order PI controller based on gain and phase margins for controlling the MABP. The beauty of the proposed technique is that the controller designed is found to give better disturbance rejection than the conventional proportional integral (PI) or the IMC-PI controllers for nominal as well as the sensitive and insensitive patients. Thus, the technique proposed here gives the dual advantage of computational simplicity as well as robust controller performance.
Vortex-Induced Vibrations of a Square Cylinder with Damped Free-End Conditions

The authors report the results of vortex-induced vibrations of a square cylinder in a wind tunnel. This constitutes a high mass ratio environment. The square cylinder is mounted in the wind tunnel in such a fashion that it only performs rigid body oscillations perpendicular to the flow direction with damped free-end conditions. This physical situation allows a direct evaluation for analytical models relying on simplified 2D assumptions. The results are also compared with two-dimensional fluid-structure (CFD-CSD) numerical simulations. The comparison shows that despite having one-dimensional motion, the analytical model does not predict the VIV region with correctness. Results show that the numerical simulations and experimental results differ from the analytical model for the prediction of reduced velocity corresponding to peak amplitude. Also the analytical reduced velocity envelope is underpredicted compared to both numerical simulations and experimental data despite the structure being lightly damped. The findings are significant as the experimental results for freely oscillating high mass ratio body show differences from the low mass ratio especially in the transition between VIV and galloping regions. However the numerical simulations show comparatively close agreement.
Visualising the nutritional performance landscapes for the black soldier fly, Hermetia illucens (Diptera: Stratiomyidae)

The black soldier fly (BSF), Hermetia illucens (Diptera: Stratiomyidae), has become one of the most economically important insects that can be a sustainable replacement for traditional feed for swine, poultry, and aquaculture. Despite its emerging importance, studies examining the nutritional requirement of BSF have been scarce. Here we used nutritional geometry approach to determine the separate and combined effects of dietary protein and carbohydrate content on multiple life-history traits and body composition linked to fitness in BSF. BSF larvae were reared on one of 32 chemically defined diets that varied in protein-to-carbohydrate ratio (P:C=1:16, 1:8, 1:4, 1:2, 1:1, 2:1, 4:1, or 8:1) and in protein plus carbohydrate concentration (P+C=60, 120, 180, or 240 g/l). Females developed more slowly into larger adults than males, but two sexes responded to dietary variation in protein and carbohydrate in a similar manner. The topography of the nutritional performance landscapes mapped for all measured traits differed significantly from one another, with the optimal P:C ratio being 1:1.71 for preadult survivorship, 1:1.56 – 1:1.11 for development time, 1:3.36 – 1:3.16 for body weight at adult emergence, and 1:1.83 – 1:1.40 for growth rate. Significant divergence in nutritional optima among these components of fitness indicates that the occurrence of fundamental life-history trade-off can be mediated by macronutrient intake. The index representing the preadult performance of BSF had a nonlinear relationship with dietary protein, with the peak centred at the intermediate P:C ratios of 1:1.43 – 1:1.37. The optimal P:C ratio was 1:2.12 – 1:1.70 for lean body weight and 1:14.14 – 1:10.82 for lipid content. Our results highlight the importance of the balanced composition of dietary protein and carbohydrate for optimising BSF performance and have implications for enhancing the mass production of this beneficial species.
Freeway drivers' willingness to pay for speeding fines

Abstract Taiwanese drivers, like most drivers, often exceed the legal speed limit and expose themselves to the risk of fine. Although the propensity to exceed the legal speed limit is common in many counties, it is of interest to understand the amount that drivers are willing to pay for driving faster than the law permits. This may provide useful guidance on the extent to which current fines are adequate as a deterrent to speeding. In this paper, the contingent valuation method (CVM) is used to measure drivers' preferences and to estimate econometric models to determine Taiwanese drivers' willingness to pay (WTP) for driving faster than the law allows. Given the high incidence on a zero WTP, a spike model is used to capture this phenomenon. The study identifies some key influences on WTP such as the personal income, the presence/absence of past violations, the risk tolerance of the driver, and the proportion of time spent on the roads where the driver exceeded the speeding limit last year. On average, the freeway drivers in various locations in Taiwan were willing to pay between $43 and $51 for driving faster than the law allows.
Very high-speed differential optoelectronic algorithmic ADC using n-i(MQW)-n SEED technology

This paper describes the design of very high speed optoelectronic analog digital converter based on a digital division algorithm called SRT division using n-i(MQW)-n self electro-optic effect device (SEED) technology. The proposed structure is a pipeline ADC. The SRT algorithm was chosen because it provides a redundancy per stage of the pipeline. The amount of redundancy is dependent on the radix of the SRT algorithm and the number set chosen. The relation between the SRT radix, number set and the division full range is given in this paper. Also a macro-model for the n- i(MQW)-n device was developed and used to simulate all the circuitry and algorithmic operations needed for the ADC. These included analog addition, analog subtraction and integer multiplication. Based on the developed macro-model and n-i(MQW)-n SEED circuit modules a basic unit of the algorithm ADC was designed.
Reliability Calculation of VANET with RSU and SP

VANET is a special type of MANET which consists of moving vehicles as nodes that form a temporary network in an Adhoc fashion. In recent years, many protocols and techniques are available to share the traffic information in VANET. This study focuses on forwarding the road safety information from source vehicle to destination vehicle with RSU (Road Side Unit) and SP (Service Provider). RSU and SP are made to transmit the information to ongoing vehicles without missing the clarity and reliability. The main objective of this study is to find the reliable path from the source vehicle to destination vehicle to transmit the traffic information. Universal Generating Function Technique (UGFT) is one of the important techniques to assess the network reliability in real life. UFGT is applied to find the reliability of nodes and links used in this VANET. Results are obtained by using Network Simulator (NS-2). Simulation results show that information dissemination with RSU and SP outperforms without RSU and SP in terms of Delay, Throughput and Packet loss.

Gamifying Employer Branding: Attracting Critical Talent in Crisis Situations like COVID-19

Abstract Companies build strong employer brands to attract, motivate, and retain employees in crises, as it necessitates engagement and building relations with recruits. This study explores the application of gamification to employer branding and recruitment by analyzing organizational objectives for gamification. Game objectives were gamification-, recruitment-, and employer branding-related. We adopted a text analytics methodology and collected data—users’ reviews (from Glassdoor and Google PlayStore) about the games they played during recruitment. The reviews showed positive and negative sentiments. We apply GAMEFULQUEST, including three components—immersion-related, achievement-related, and social-related—based on self-determination theory and related them to employer brand equity and employer brand engagement.
Tri-band bandpass filters using modified tri-section stepped impedance resonator with improved selectivity and wide upper stopband

This study presents tri-band bandpass filters using two variant designs based on tri-section stepped impedance resonators (SIR) to achieve passband selectivity. The passbands are centred about 2.4, 3.5 and 5.5 GHz, respectively. The first design pertains to an asymmetric stepped impedance stub-loaded tri-section SIR and the second one consists of embedded SIR. Both the techniques contribute in improving the selectivity by inserting transmission zero between first passband and second passband. With a simple extension of one of the input/output coupling feed lines transmission zeros are inserted between second and third passband. The filter exhibits a wide stopband till 10 GHz because of, cascading with the feed line, a low-pass filter with upper cutoff at 6.4 GHz. The passband insertion loss is within 2 dB. The group delay excursion for both the developed filters for the three passband suggests linearity of phase. Fabricated prototypes for both the variants are realised with simulated and measured results in good agreement.
