Real time system for measuring the pantograph vertically movement

The measuring of the geometrical parameters regarding the contact line in electric railway transportation presumes a real time acquisition system with high accuracy transducers. Present paper proposes a system for measuring in real time the pantograph vertically movement, which contains a host computer, an integrated controller NI MyRIO, a temperature sensor and an ultrasonic distance sensor. The computing application can display the time variation of measured distance using numerical filters and also to save the information into data files. Real time module provides accuracy, giving a precise timing to acquiring and processing subroutines. Presented method is tested using a laboratory pantograph.
Assessment of psychological problems in schoolgoing adolescents of Aligarh

Background: Adolescence is a period of physical, nutritional, and sexual transition, also remarkable for the accompanying psychological changes. Worldwide, 20% of children and adolescents suffer from a disabling mental illness. Therefore, knowledge of the prevalence of these disorders can be used to design intervention strategies. The present study was conducted in the 13–15 years' age group schoolgoing adolescents, with the objective to estimate the prevalence of psychological morbidity, employing Strength and Difficulties Questionnaire (SDQ). Materials and Methods: A cross-sectional analytical study was conducted in three different schools of Aligarh, in the 13–15 years' age group, with a prior permission from the school authorities. The study was approved by a multidisciplinary Institutional Ethics and Research Advisory Committee. Results: A total of 1456 students were sampled for the study. The prevalence of psychological morbidity on the basis of total difficulties score was found to be 9.75% (95% confidence interval - 8.33–11.39). The prevalence of emotional, conduct, hyperactivity, peer, and prosocial problems was 5.42%, 5.56%, 3.78%, 4.40%, and 4.26%, respectively. Conclusions: Psychological problems are fairly common in the adolescent age group. Despite the need, there is a dearth studies conducted in this crucial age group in India. Of the studies available, a wide variance is reported either due to the difference in diagnostic tools or due to the types of psychological disorders considered in different researches. For the purpose of uniformity and comparability, SDQ stands as a good option.
Concern about the Expanding Prescription Drug Epidemic: A Survey of Licensed Prescribers and Dispensers.

BACKGROUND Prescription drug misuse and abuse has reached epidemic levels in the U.S., and stands as a leading cause of death. As the primary gatekeepers to the medications contributing to this epidemic, it is critical to understand the views of licensed health care professionals. OBJECTIVE In this study, we examine health care professionals' concern regarding prescription drug abuse in their communities and the impact their concern has had on their prescribing and dispensing practices. STUDY DESIGN An online survey of licensed health care providers. SETTING Conducted in Indiana. METHODS This study was a state-wide evaluation of Indiana's prescription drug monitoring program. The questionnaire asked respondents how concerned they were about prescription drug abuse in their community. Variation in the level of concern was examined using ordinary least squares regression and information about the respondents' demographic background and clinical experience. In addition, we used logistic regression to examine whether concern was associated with changing prescribing and/or dispensing behavior. RESULTS The majority of providers indicated they were "moderately" or "extremely concerned" about prescription drug abuse in their communities. The level of concern, however, varied significantly by profession, with pharmacists, physicians, nurse practitioners/physician assistants being more concerned than dentists. Additional analyses indicate that providers with higher levels of concern were those who also reported recently changing their prescribing and/or dispensing behavior. LIMITATIONS The voluntary nature and geographical focus of the study limits the generalizability of the findings. CONCLUSION Concern about prescription drug abuse is generally high across the major health care professions; however, a significant minority of providers, particularly among dentists, expressed little or no concern about the epidemic. Increasing health care providers' general level of concern about prescription drug abuse may be an effective public health tool for encouraging voluntary reductions in prescribing and/or dispensing controlled substances.
Channel Estimation With Systematic Polar Codes

Study of polar codes in fading channels is of great importance when applying polar codes in wireless communications. Channel estimation is a fundamental step for communication to be possible in fading channels. Construction of both systematic and nonsystematic polar codes is based on an information set and the known frozen bits. Efficient implementation of systematic and nonsystematic polar codes exists. When it comes to channel estimation or channel tracking, additional pilot symbols are inserted in the codeword traditionally. In this paper, to improve the performance of polar codes in the finite domain, pilot symbols are selected from the coded symbols themselves. In order to keep the existing efficient structure of polar code encoding, pilot selection is critical since not all selections can reuse the existing structure. In this paper, two pilot selections denoted as Uneven Pilot Selection (UEPS) and Even Pilot Selection (EPS) are proposed, which do not change the efficient polar encoding structure. The proposed UEPS and EPS are proven to satisfy the efficient construction condition. The performance of EPS is shown in this paper to outperform both the UEPS and the traditional pilot insertion scheme. The simulation results provided verify the performance of the proposed pilot selection schemes.
A miniaturized tapered slot antenna with ultra-wide bandwidth

A miniaturized tapered slot antenna is proposed in this paper. The antipodal Vivaldi antenna is fed by the designed microstrip line and resistive loading is used to greatly reduce dimension of the antenna. In addition, a parasitic patch is stuck on the antenna to the increase the antenna's gain. The grid etched on the edge of the antenna is used to reduce the reflection and improve radiation performance. The dimension of the proposed antenna is 75mm × 74mm × 2mm. The measured results show that the bandwidth extends from 0.7 GHz to 6.2 GHz (S11 <; -10dB), while the gain varies from -2dB to 9.4dB, which are in agreement with simulated results by HFSS. Due to the good radiation performance of the antenna, it can be used for ultra-wideband systems which have strict demand for dimension.
Expected Utility Preferences for Contingent Claims and Lotteries

In Arrow’s seminal analysis of optimal risk bearing in which he introduced contingent claim securities, he assumed preferences were representable by a state independent Expected Utility function. Although the classic contingent claim setting assumes agents choose over contingent consumption vectors conditioned on a fixed set of probabilities, later work on information economics suggested that allowing probabilities to change across contingent claim spaces could be an interesting extension. However the set of axioms that are necessary and sufficient for the existence of an Expected Utility representation for the classic contingent claim space with a fixed set of probabilities does not ensure that this form utility extends across multiple contingent claim spaces. In this paper, we derive a set of axioms on preferences which are necessary and sufficient for the existence of an Expected Utility representation when probabilities change. We also consider the incremental axioms which are necessary and sufficient for Expected Utility preferences to extend to the classic lottery setting of von Neumann and Morgenstern, where agents choose not only over consumption vectors but also over probabilities vectors.
Rolling-circle amplification detection of thrombin using surface-enhanced Raman spectroscopy with core-shell nanoparticle probe.

An ultrasensitive surface-enhanced Raman spectroscopy (SERS) sensor based on rolling-circle amplification (RCA)-increased "hot-spot" was developed for the detection of thrombin. The sensor contains a SERS gold nanoparticle@Raman label@SiO2 core-shell nanoparticle probe in which the Raman reporter molecules are sandwiched between a gold nanoparticle core and a thin silica shell by a layer-by-layer method. Thrombin aptamer sequences were immobilized onto the magnetic beads (MBs) through hybridization with their complementary strand. In the presence of thrombin, the aptamer sequence was released; this allowed the remaining single-stranded DNA (ssDNA) to act as primer and initiate in situ RCA reaction to produce long ssDNAs. Then, a large number of SERS probes were attached on the long ssDNA templates, causing thousands of SERS probes to be involved in each biomolecular recognition event. This SERS method achieved the detection of thrombin in the range from 1.0×10(-12) to 1.0×10(-8) M and a detection limit of 4.2×10(-13) M, and showed good performance in real serum samples.

Inclusive Nature-Based Solutions for Urban Regeneration in a Natural Disaster Vulnerability Context: A Case Study of Chongqing, China

Currently, economic development has become a dominant factor in the promotion of urban regeneration in China. This means that decision makers often overlook the impacts on the natural environment when planning urban regeneration within a region. To properly face such challenges and others that may arise, a strategy relying on Nature-Based Solutions (NBS) can enhance the physical and ecological environment of a city, while ensuring greater resilience to natural disasters, and the use of fewer resources. NBS also improves the social well-being of citizens by creating more inclusive and engaged communities. This paper reviews the literature concerning urban regeneration and natural disaster vulnerability to discuss the complex mechanisms of the interactions between natural disaster and urban regeneration. Then, the evaluation model of natural disaster vulnerability in urban area is constructed, and data envelopment analysis (DEA) model is used to assess the vulnerability of natural disasters in various regions of Chongqing. Finally, under the background of NBS, this paper puts forward the way of urban regeneration, and provides an important direction for urban regeneration to realize the sustainable development of cities.
Symbol Recognition by Error-Tolerant Subgraph Matching between Region Adjacency Graphs

We propose an error-tolerant subgraph isomorphism algorithm formulated in terms of region adjacency graphs (RAG). A set of edit operations to transform one RAG into another one are defined as regions are represented by polylines and string matching techniques are used to measure their similarity. The algorithm follows a branch and bound approach driven by the RAG edit operations. This formulation allows matching computing under distorted inputs and also reaching a solution in a near polynomial time. The algorithm has been used for recognizing symbols in hand drawn diagrams.
Safety of a New Amino Acid Formula in Infants Allergic to Cow's Milk and Intolerant to Hydrolysates

Objectives: Amino acid–based formulas (AAFs) are recommended for children with cow's-milk allergy (CMA) failing to respond to extensively hydrolysed formulas (eHFs). We evaluated the effects of a new thickened AAF (TAAF, Novalac), containing a pectin-based thickener, and a reference AAF (RAAF, Neocate) on allergy symptoms and safety, through blood biochemistry analysis and growth. Methods: Infants (ages < 18 months) with CMA symptoms failing to respond to eHFs were randomised in a double-blind manner to receive TAAF or RAAF for 3 months. All of the infants were then fed TAAF for 3 additional months. Paediatric visits occurred at 1, 3, and 6 months. Blood samples were collected at inclusion and 3 months. Results: Results at 1 month were previously described. The 75 infants with proven CMA and eHF intolerance tolerated their allocated formula. At 3 months, the dominant allergic symptom had disappeared in 76.2% of the infants with TAAF and in 51.5% of the infants with RAAF (P = 0.026). The Scoring Atopic Dermatitis Index significantly improved more with TAAF than with RAAF (−27.3 ± 2.3 vs −20.8 ± 2.2, P = 0.048). Of the infants, 92.9% had normal stools (soft or formed consistency) with TAAF vs 75.8% with RAAF (P = 0.051). More infants in TAAF group had better quality of nighttime sleep (P = 0.036) and low frequency of irritability signs (P < 0.001). With both formulas, all of the biochemical parameters were within normal ranges. There were no differences between the 2 groups in any of the anthropometric z scores. Conclusions: The new TAAF was tolerated by all of the infants with CMA and intolerance to eHFs. Anthropometric and clinical data showed that both formulas were safe.
MMSE soft-interference-cancellation aided MCMC detection for MIMO systems

A novel MCMC detection algorithm in MEMO systems is proposed. The Gibbs samples are initialized through a new way after integrating the Minimum Mean Square Error soft-interference-cancellation (SIC-MMSE) algorithm and the convergence of the Markov chain is accelerated. Comparison with the conventional MCMC algorithm shows the novel algorithm performs better with equal number of Gibbs samples, that is, equal complexity. It is proved that our proposed SIC-MMSE-aided MCMC algorithm has superior performance.
A ug 2 00 8 Stationary non-equilibrium properties for a heat conduction model

We consider a stochastic heat conduction model for solids composed by N interacting atoms. The system is in contact with two heat baths at different temperature Tl and Tr. The bulk dynamics conserve two quantities: the energy and the deformation between atoms. If Tl 6= Tr, a heat flux takes place in the system. For large N , the system adopts a linear temperature profile between Tl and Tr. We establish the hydrodynamic limit for the two conserved quantities. We introduce the fluctuations field of the energy and of the deformation in the non-equilibrium steady state. As N goes to infinity, we show that this field converges to a Gaussian field and we compute the limiting covariance matrix. The main contribution of the paper is the study of large deviations for the temperature profile in the non-equilibrium stationary state. A variational formula for the rate function is derived following the recent macroscopic fluctuation theory of Bertini et al.
Interface Framework to Drive an Intelligent Wheelchair Using Facial Expressions

Many of the physically injured use electric wheelchairs as an aid to locomotion. Usually, for commanding this type of wheelchair, it is required the use of one's hands and this poses a problem to those who, besides being unable to use their legs, are also unable to properly use their hands. The aim of the work described here, is to create a prototype of a wheelchair command interface that do not require hand usage. Facial expressions were chosen instead, to provide the necessary visual information for the interface to recognize user commands. The facial expressions are captured by means of a digital camera and interpreted by an application running on a laptop computer on the wheelchair. The software includes digital image processing algorithms for feature detection, such as colour segmentation and edge detection, followed by the application of a neural network that uses these features to detect the desired facial expressions. The results obtained from the framework interface provide strong evidence that it is possible to comfortably drive an intelligent wheelchair using facial expressions.
Log Record Daemon Windows WindowsWindows Applica ons QEMU Controller DMA Recorder Linux WindowsLinux Applica ons QEMU Controller DMA Recorder Virtual Machine Linux Applica ons KVM Linux Virtual Machine Record and Replay Component Memory Interleaving

Deterministic replay, which provides the ability to travel backward in time and reconstruct the past execution flow of a multiprocessor system, has many prominent applications. Prior research in this area can be classified into two categories: hardware-only schemes and software-only schemes. While hardware-only schemes deliver high performance, they require significant modifications to the existing hardware. In contrast, software-only schemes work on commodity hardware, but suffer from excessive performance overhead and huge logs. In this article, we present the design and implementation of a novel system, Samsara, which uses the hardware-assisted virtualization (HAV) extensions to achieve efficient deterministic replay without requiring any hardware modification. Unlike prior software schemes which trace every single memory access to record interleaving, Samsara leverages HAV on commodity processors to track the read-set and write-set for implementing a chunk-based recording scheme in software. By doing so, we avoid all memory access detections, which is a major source of overhead in prior works. Evaluation results show that compared with prior software-only schemes, Samsara significantly reduces the log file size to 1/70th on average, and further reduces the recording overhead from about 10×, reported by state-of-the-art works, to 2.1× on average.
Critical Short Circuit Ratio Analysis on DFIG Wind Farm with Vector Power Control and Synchronized Control

The introduction of renewable energy sources into the AC grid can change and weaken the strength of the grid, which will in turn affect the stability and robustness of the doubly-fed induction generator (DFIG) wind farm. When integrated with weak grids, the DFIG wind turbine with vector power control often suffers from poor performance and robustness, while the DFIG wind turbine with synchronized control provides better stability. This paper investigates the critical short circuit ratios of DFIG wind turbine with vector power control and synchronized control, to analyze the stability boundary of the DFIG wind turbine. Frequency domain methods based on sensitivity and complementary sensitivity of transfer matrix are used to investigate the stability boundary conditions. The critical capacity of DFIG wind farm with conventional vector power control at a certain point of common coupling (PCC) is obtained and is further increased by employing synchronized control properly. The stability boundary is validated by electromagnetic transient simulation of an offshore wind farm connected to a real regional grid.
Knowledge Spillovers And Local Innovation Systems: A Critical Survey

This paper re-examines critically the growing literature on localized knowledge spillovers (LKSs), and finds the econometric evidence on the subject still lacking a firm theoretical background, especially in relation to the more recent developments in the economics of knowledge. LKSs as externalities are too narrow a concept to embrace the wide variety of knowledge transmission mechanisms that may, or may not, spread ideas and expertise while keeping the diffusion process bounded in space.

Measuring the Quality of the Tourist Experience: the Case Study of the Azores

Por um desenvolvimento sustentável da actividade turística entende-se aquele que permite aumentar a qualidade de vida da população residente, promover a melhoria da qualidade da experiência turística, maximizar a rentabilidade das empresas locais e os efeitos multiplicadores do turismo e optimizar os impactes do turismo, assegurando um equilíbrio entre os benefícios económicos e os custos ambientais e socioculturais. Neste trabalho de investigação avalia- se uma das vertentes do conceito de sustentabilidade do turismo para o caso do destino turístico Açores: a qualidade da experiência turística. Atendendo à natureza subjectiva da qualidade do produto turístico, foi implementado um questionário a uma amostra de 400 turistas à saída da Região, durante a época alta (Verão), para se determinar a importância atribuída a um conjunto de vinte e cinco atributos na escolha do destino turístico Açores (expectativas), bem como a satisfação obtida na visita (percepções) perante esses mesmos atributos, de modo a avaliar o desempenho do destino turístico. A paisagem e a natureza foram os atributos considerados mais importantes na escolha do destino turístico, sendo igualmente aqueles que mais contribuíram para a satisfação com a visita. A satisfação média excedeu a importância média atribuída a todos os atributos e foram encontradas diferenças significativas em onze atributos. Através da aplicação da análise factorial, foram identificados seis factores subjacentes à escolha do destino turístico e cinco factores subjacentes à satisfação com a visita. A análise de clusters hierárquica permitiu revelar a presença de três grupos distintos de turistas com base na satisfação obtida na visita: os Encantados (37,5%), os Descobridores (47,7%) e os Sociáveis (14,8%). A qualidade da experiência turística influencia a intenção de regresso e a recomendação do destino.
Idiom-Aware Compositional Distributed Semantics

Idioms are peculiar linguistic constructions that impose great challenges for representing the semantics of language, especially in current prevailing end-to-end neural models, which assume that the semantics of a phrase or sentence can be literally composed from its constitutive words. In this paper, we propose an idiom-aware distributed semantic model to build representation of sentences on the basis of understanding their contained idioms. Our models are grounded in the literal-first psycholinguistic hypothesis, which can adaptively learn semantic compositionality of a phrase literally or idiomatically. To better evaluate our models, we also construct an idiom-enriched sentiment classification dataset with considerable scale and abundant peculiarities of idioms. The qualitative and quantitative experimental analyses demonstrate the efficacy of our models.
