An improved cochlea model with a general user interface

We have developed a flexible ID cochlea model to test hypotheses and data against physical and mathematical constraints. The model is flexible in the sense that several linear and nonlinear model characteristics can be selected, and different boundary conditions can be tested. The software model runs at a reasonable speed at a modern PC. As an example, we will show the results of the model in comparison with the systematic study of the phase behavior (group delay) of distortion product otoacoustic emissions (DPOAEs) in the guinea pig (S. Schneider, V. Prijs and R. Schoonhoven, [9]). We also will demonstrate the effects of some common non-physical boundary conditions. Finally, we briefly indicate that this model of the auditory periphery provides a superior front end for an ASR (automatic speech recognition)-system.

Determination of stability of epimetamorphic rock slope using Minimax Probability Machine

The article employs Minimax Probability Machine (MPM) for the prediction of the stability status of epimetamorphic rock slope. The MPM gives a worst-case bound on the probability of misclassification of future data points. Bulk density (d), height (H), inclination (β), cohesion (c) and internal friction angle (φ) have been used as input of the MPM. This study uses the MPM as a classification technique. Two models {Linear Minimax Probability Machine (LMPM) and Kernelized Minimax Probability Machine (KMPM)} have been developed. The generalization capability of the developed models has been checked by a case study. The experimental results demonstrate that MPM-based approaches are promising tools for the prediction of the stability status of epimetamorphic rock slope.

This study aims to evaluate Micro, Small and Medium Enterprises - (MSMEs) conditions of access to credit under Brazil´s main earmarked credit programs: National Economic and Social Development Bank (BNDES) financings, the Constitutional Financing Funds of the North, Northeast and Center-West regions (FNO, FNE, FCO), and the Employment and Income Generation Program (Proger). These programs were originally assessed by the author in a research report drawn up for the Economic Commission for Latin America and the Caribbean (Eclac), and this study updates information and adds new analyses. In 2004, the total value of credit granted to firms of all sizes under the three credit programs analyzed reached US$ 16.783 million (or 2,3% of GDP), of which US$ 4.613 million were lent to MSMEs, or 27.5 % of all financings. Programs using earmarked funds constitute the only source of financings formedium and long-term investment, as Brazil does not have a private credit market ofthis kind. Earmarked credit programs´ supply of working capital loans has also grown.
Vibration characteristics of OH-58A helicopter main rotor transmission

Abstract : Experimental vibration tests covering a range of torque and speed conditions were performed on the OH-58A helicopter main rotor transmission at the NASA Lewis Research Center. Signals from accelerometers located on the transmission housing were analyzed by using Fourier spectra, power spectra, power spectral density functions, and averaging techniques. Most peaks of the Fourier spectra occurred at the spiral bevel and planetary gear mesh harmonics. The highest level of vibration occurred at the spiral bevel and planetary gear mesh harmonics. The highest level of vibration occurred at the spiral bevel meshing frequency. Transmission speed and vibration measurement location had a significant effect on measured vibration; transmission torque and measurement direction had a small effect.
The importance of recruitment and selection process for sustainability of total quality management

Management literature discusses that the behavioral traits of employees can play an important role in the success of total quality management (TQM). However, little empirical research exists in this regard. Using an international dataset, the present study investigates: the impact of quality management practices on plant competitiveness; and the moderating effect of an employee selection process on the relationship between quality management practices and plant competitiveness. Results show that quality management practices positively impact plant competitiveness. Furthermore, the behavioral traits of employees seem to have a significant impact on the effectiveness of quality management practices. This implies that managers should pay close attention to prospective employees’ behavioral traits and their fit with the TQM philosophy. Managers should not limit their attention to potential employees’ technical skills.

Mood and Vulnerability Prediction through Natural Language Processing

Analyzing various phases of mood using the verbal form of writing can serve as advancement in the field of psychology. The research work highlighted in this paper focuses on the use of sentiment analysis to predict the emotional state and vulnerability of written statements, as per the most generic perceptions, in the English language, with the help of an algorithm. The text pre-processing step discussed in this work involves cultivating and analyzing each word of user input, analyzing their literal and emotional essences to sum up the mood inclination of the statements and other parts-of-speech, to determine the specific mood and the vulnerability of the writing itself. The vulnerability level of the document is also determined, in order to extent out the purpose towards medical treatments where a vulnerable mindset, suffering from mental illness, depression, perceives the capability to inflict harm upon oneself or others can be given proper help and counseling.

Elaboration of analytical thermo-mechanical cutting model matched by numerical and experimental results

The global aim of this paper is to propose a complete analytical model concerning the material removal. In order to take into account all the aspects of the process, a “phenomena split approach”, based on the assumption that the material removal is the summation of three major contributions, ploughing, spring back and “pure cut” was adopted. This new methodology is developed on the base of experimental tests and industrial experience. In fact the chip is not systematically present. When the chip exists, a part of theoretical layer of the material to be removed is transformed in lateral burrs and elastic compression under the tool tip. In this paper this new approach is presented and the “pure cut” contribution is developed in details. This analytical sub-model of chip formation is calibrated and fitted with a finite element modeling, in order to presents new hypothesis and new formula based on the physics close to the tip of the tool. The chip is considered rigid and uniform, and the regime is supposed stationary. Thermo-mechanical law is applied in shear zones where plastic strain, temperature and strain rate are concentrated. The model takes into account the cutting edge radius too, using an equivalent cutting angle. The friction coefficient at the interface tool-chip is also analytically computed and the present model is considered predictive.DOI: http://dx.doi. org/10.5755/j01.mech. 18.6. 3161

Gait definition and successive gait-transition method based on energy consumption for a quadruped

In nature, to realize the smooth motion for different speeds, the continuous gait transition is usually required for the quadrupeds. Thus, the gait simulation of quadrupeds is a requisite step to obtain the stable and energy-efficient gait for the walking machines. In this paper, the definitions of the two gait parameters, phasic difference and duty factor are presented, which can determine the gait of the quadrupeds. Then, several typical gaits of the quadrupeds are analyzed such that the seven standard gaits and corresponding parameters are summarized. Additionally, the variance law of the two parameters, which determine the relationship of gait transition, is analyzed. Furthermore, the quadruped gait derivative spectrum (QGDS) is proposed and the gait definition of the quadrupeds is presented. To minimize the power consumption, the choice criterion of gait, the optimal gait in terms of the motion speed, duty factory, and power consumption for the walking machines, is developed. Last, the continuous variance of the gait is implemented by the simulation of the gait transition from walk to trot, which evaluate the choice criterion and transition of gait.

Investigation of hot roller embossing for microfluidic devices

Microfluidics for most bio-related diagnostic applications typically requires single usage disposable chips to avoid bio-fouling and cross-contamination. Individual piece-wise manufacturing of polymeric microfluidic devices has been widely employed in recent years. To significantly lower the manufacturing costs, one possible way is to improve the production yield of polymer microfluidic chips via the hot roller embossing method. This paper discusses the effects of varying the process parameters such as roller temperature, applied pressure and substrate preheating during hot roller embossing (according to a systematic set of experiment designs) and its influence on the corresponding mold to pattern fidelity in terms of normalized embossed depths on the poly(methylmethacrylate) (PMMA) substrate. Concurrently, pattern density studies on the mold were also conducted. Functional testing in terms of fluid flow and micromixing was carried out to evaluate the feasibility of using hot roller embossed PMMA substrates as microfluidic chips.

Solvency II bij verzekeraars: een analyse van jaarrekeningen

In dit artikel wordt op basis van jaarverslagen onderzocht in hoeverre verzekeraars klaar zijn voor Solvency II, het nieuwe wettelijke toezichtskader voor verzekeraars. We kijken naar de organisatorische vereisten van Solvency II en toetsen deze aan beschikbare informatie vanuit jaarverslagen van een aantal grote Europese verzekeraars. Onze conclusie is dat de meeste verzekeraars goed op weg zijn in hun voorbereiding, maar op dit moment een aantal cruciale verbeteringen moeten doorvoeren. Verzekeraars zouden zich moeten richten op dataverzameling die benodigd is voor het bepalen van bijvoorbeeld correlaties. Qua risico-governance zijn er veel verschillen tussen verzekeraars. Operationeel risicomanagement wordt steeds meer beschreven in de jaarverslagen, maar goede interne risicomodellen zijn nog onvoldoende beschikbaar. We eindigen met enkele aandachtspunten in het implementatieproces van Solvency II.
Proposition of Framework for Quality Working Environment Based on Sustainable Design in Small Manufacturing Enterprises

Quality improvements are implemented through various systems, techniques and tools in a company. The implementation of quality initiatives are commonplace in large companies rather than the smaller ones. Small and medium-sized enterprises (SMEs) are usually constrained by their size, expertise and financial resources. Nevertheless, it is important for them to improve their quality of physical work setting and working environment to sustain a competitive advantage. 5S is one of the most widely adopted techniques for industrial housekeeping and, in improving the quality of workplace environment. Since the cost of the development and implementation is one of the main constraints for 5S program at workplace in SMEs, the sustainable design concept shall be adopted. As the main part of the research work, a conceptual model of continuous improvement initiative for quality working environment within small and medium-sized manufacturing companies was developed and proposed. The focus of this research study is on the aspect of how to implement the 5S practices by incorporating sustainable design for improving a quality workplace environment and reducing the environmental impacts through a comprehensive approach. Finally, conclusions are drawn and suggestions made for further research in SME companies.
The preliminary investigation of potential response biomarkers to air pollution (PAHs) exposure on childhood asthma

Background In recent five years, air quality in China has been gradually improved; however, the prevalence of asthma in China has still increased significantly. This study aims to examine whether air pollution exposure is a significant contributor to childhood asthma and to explore the mechanisms using exposure and response biomarkers. Methods The generalized additive model was applied to evaluate the effects of air pollutants on asthma hospitalization. Urinary 1-hydroxypyrene (1-OHPyr) was determined as PAHs exposure biomarker. Metabolic profiles and microbial diversity were screened and selected as response biomarkers. Results Daily average concentrations of the six common air pollutants were not significantly associated with daily childhood asthma hospitalization. Urinary 1-OHPyr level showed large variability among asthmatic children and were positively correlated with the abundance of Prevotella (genus level) and purine metabolism. Conclusions The biomarker of PAHs exposure is associated with metabolic and microbiological biomarkers of childhood asthma. As the potential health risk, we suggest that PAHs should be included in the national monitoring system aiming to reduce the exposure.
