Theoretical analysis of polarisation-insensitive wavelength conversion by four-wave mixing in photonic crystal fibre

Polarisation-insensitive wavelength conversion by four-wave mixing (FWM) has been demonstrated in a 20 m short nonlinear photonics crystal fibre. Theoretical analysis confirms that the combination of a 45° pump launch and a minimum pump-probe detuning is required to reduce the polarisation sensitivity of FWM to ∼1 dB.
Risk and economics of disease introduction into dairy farms.

A well closed farming system will enhance the success of disease eradication programs, because introduction or reintroduction of infectious diseases are less likely. The economic implications of a more closed farming system will not always been obvious for farmers. The management decisions need to be made for different parts of the farm and are farm-specific. The objective of the study was to obtain input for and to develop an on-farm decisions support model to calculate the economic consequences of a more closed farming system. The input was based on IBR, since there were numerous data on this disease, but a more closed farming system will prevent introduction of other diseases as well (i.e. Bovine Virus Diarrhoea Virus (BVDV), Leptospira interrogans serovar hardjo (L. hardjo) , and Salmonella enterica subsp. enterica serotype Dublin (S. dublin) ). Direct animal contacts such as purchase of cattle, participating in cattle shows, and cattle that breach or escape and mingle with other cattle were found to be important risk factors for introduction of Bovine Herpesvirus type 1 (BHV1). Furthermore, the use of protective farm clothing was found to be an important preventive factor. The effect of a BHV1 outbreak on milk production was estimated with a random effect model. An outbreak of BHV1 on a BHV1-free farm, caused limited milk production losses of on average 39 kg per cow during the outbreak, but the variability was high (95% CI 1-77 kg). Nine percent of Dutch BHV1-free dairy farms that were also at risk for BVDV, L. hardjo and/or S. dublin had one introduction per year of one of these four diseases. All these results were incorporated in the static, deterministic economic model. The management measures to reduce the probability of introduction of BHV1, the costs of these measures, and the risk reduction of these measures were obtained from other sources. Costs were calculated by using partial budgeting. The model was verified and partly validated and a sensitivity analysis was carried out to obtain insight into the model behaviour. A hypothetical 55-cow dairy farm that refrained from purchasing cattle, provided protective clothing to professional visitors and a temporary worker, and placed a double fence on six ha. of land to prevent over the fence contacts, had to spend Dfl. 4495 in five years. The probability of disease introduction was decreased by 74%. The avoided losses for disease introduction amounted to Dfl. 7033 over five years. The benefit of becoming more closed for this hypothetical farm was Dfl. 2538. The implementation of a more closed system will be profitable for most farms. The profitability will increase when a farm is at risk for more diseases, but will decrease when farms are limited in their facilities to rear replacement heifers or when a large amount of pasture adjoins pasture of other cattle farms.

Dual‐mode resonator with modified dual‐square‐Loop for WLAN and WiMAX quad‐band filter design

We propose the improved configurations with dual‐mode dual‐square‐loop resonators (DMDSLR) for quad‐band bandpass filter (BPF) design. The modified DMDSLR filter employs two sets of the loops. The square loop is designed to operate at the first and third resonated frequencies (2.4/5.22 GHz) and the G‐shaped loop is employed at the second and fourth resonated frequencies (3.59/6.6 GHz). The resonant frequency equations of DMDSLR are introduced for simply designing quad‐band BPF. Resonant frequencies can be controlled by tuning the perimeter ratio of the square loops. A systematic design procedure with the design map is applied for accuracy design. To obtain lower insertion loss, higher out‐of‐band rejection level and wider bandwidth of quad‐band, the miniaturized DMDSLR with meander‐line technique is proposed. The proposed filters are successfully simulated and measured showing frequency responses and current distributions. It can be applied to WLAN and WiMAX quad‐band systems. © 2013 Wiley Periodicals, Inc. Int J RF and Microwave CAE 24:332–340, 2014.
A WIRELESS APPROACH TO DEVICE-FREE LOCALISATION (DFL) FOR INDOOR ENVIRONMENTS

Determining the location of individuals within indoor locations can be useful in various scenarios including security, gaming and ambient assisted living for the elderly. Healthcare services globally are seeking to allow people to stay in their familiar home environments longer due to the multitude of benefits associated with living in non-clinical environments. Technology to determine an individual's movements or lack of movement is key to ensuring that home emergencies are detected and responded to promptly. This paper proposes a device-free wireless-based localisation (DFL) system which would enable the individual to proceed with normal daily activities without the constraint of having to wear a traceable device. The principal behind this is that the human body absorbs/reflects the radio signal being transmitted from a transmitter to one or more receiving stations. The system design procedure facilitates the use of a minimum number of wireless nodes with the aid of a principle component analysis (PCA) based intelligent signal processing technique. Results demonstrate that human detection and tracking are possible to within 1m resolutions with a minimal wireless hardware infrastructure. (6 pages)
The fog influence on bit error ratio

The free space optic links are used in places, where it is very difficult to use optical fiber links. The advantages of free space optic link are a great bit rate, easy and fast installation, unlicensed frequency band. The greatest disadvantage is transmission medium, which it uses in case of FSO link, the atmosphere. The worst influence on FSO link is caused by atmospherical effect called fog. This article deals with the study of fog influence on FSO link and its bit error ratio. The real measurement of BER with artificial generated fog and FSO link was performed. The measurement was done in laboratory conditions. The results are presented in this article.
Immersive 3D Visualization of the Collective Behavior of Particles and Crystal Dislocations Using Virtual Reality Technology

In this article, we present a three-dimensional visualization technique that has been developed in order to establish an interactive immersive environment to visualize the particles in granular materials and dislocations in crystals. Simple elementary objects often exhibit complex collective behavior. Understanding of such behaviors and developments of coarse-scale theories, often requires insight into collective behavior that can only be obtained through immersive visualization. By displaying the computational results in a virtual environment with three-dimensional perception, one can immerse inside the model and analyze the intricate and very complex behavior of individual particles and dislocations. We built the stereographic images of the models using OpenGL rendering technique and then combine with the Virtual Reality technology in order to immerse in the three-dimensional model. A head mounted display has been used to allow the user to immerse inside the models and a flock of birds tracking device that allows the movements around and within the immersive environment.

The Development of Optical See-through Display Based on Augmented Reality for Oral Implant Surgery Simulation

AbstractThe aim of this paper is to develop an optical see-through display (OSTD) system applied to the oral implant training. The proposed system includes the calibration, virtual objects and augmented reality (AR) visualization. For the image on the mirco display is projected through the lens and located between the lens and the focal point. The calibration is used to determine the intrinsic camera parameters. In addition, the transformation among the human’s eye, the tracking camera and the magnification of the lens can be computed by the geometry calibration. Finally, the virtual objects can be superimposed upon an existing scene and registered correctly during the tracking. For AR visualization, the useful information, such as the nerve canal, can be viewed during the training. Finally, the proposed system can provide an efficient, stable and realistic method for users in the oral implant operations.

Analysis of Barriers to the Utility of General Aviation Based on a User Survey and Mode Choice Model

General aviation is an underutilized transportation mode, particularly when compared to alternative modes such as the automobile and the commercial airlines. In this research, barriers to the utility of general aviation were identified through a web-based survey of active general aviation pilots, with 1,471 surveys returned and suitable for analysis. The survey data indicated five key barriers which were thought by pilots to be currently reducing their ability to utilize general aviation transportation to its fullest extent: weather, expense of the travel mode, a lack of mobility at the destination, doorstep-to-destination travel time, and reduced access to general aviation transportation. A mode choice model was also constructed to further examine some of these barriers, including travel expense and doorstep-to-destination travel time. While the model considered only key quantitative factors such as travel distance, time and the travelers' value of time, it proved to be quite powerful in demonstrating how general aviation utility is affected by changes in the key factors. From the survey data, and analysis with the mode choice model, several key issues emerge as being important to increasing the utility of general aviation transportation. Improved weather information, including real-time information in the aircraft cockpit, as well as near all-weather capability for general aviation aircraft and better access to ground transportation at the travel destination would significantly increase utility. Furthermore, modifying the business model for owning and operating general aviation aircraft may be the best near-term strategy for lowering the expense of general aviation transportation. Analysis with the mode choice model also indicates that increasing the speed of general aviation aircraft will not necessarily translate into an increase in the utility of general aviation transportation.

Optimum and Suboptimum Estimator Performance for Multibaseline InSAR

Multibaseline methods have been recently proposed to reduce problems of phase ambiguity and data noise in SAR interferometry for topographic mapping. Both phase-only interferometry and direct processing of the complex multibaseline data have been considered. In this paper, two non-model based multibaseline estimators and two recently proposed model based algorithms are discussed and compared in terms of statistical accuracy of the reduced-ambiguity phase estimate. It is shown that model-based processing of the complex multibaseline data can be significantly more efficient than the other methods. Übersicht Mehrbasen-SAR-Interferometrie ist in den letzten Jahren zur Verringerung der Problematik von Phasenmehrdeutigkeiten sowie des Phasenrauschens in Zusammenhang mit der topographischen Kartierung empfohlen worden. Sowohl die alleinige Auswertung der interferometrischen Phasen wie auch die direkte Prozessierung der komplexwertigen Daten sind bisher vorgeschlagen worden. In diesem Beitrag werden zwei Schätzer zur nicht-modellbasierten sowie zwei weitere zur modellbasierten Mehrbasen-SAR-Interferometrie vorgestellt. Ein Vergleich bezüglich der statistischen Genauigkeit der reduzierten mehrdeutigen Phasenschätzung zeigt, daß die modellbasierte Prozessierung der komplexwertigen Daten gegenüber den anderen Methoden bedeutend effizienter ist.

MASST: A Web-based Basic Mass Spectrometry Search Tool for Molecules to Search Public Data

We introduce a web-enabled small-molecule mass spectrometry (MS) search engine. To date, no tool can query all the public small-molecule tandem MS data in metabolomics repositories, greatly limiting the utility of these resources in clinical, environmental and natural product applications. Therefore, we introduce a Mass Spectrometry Search Tool (MASST) (https://proteosafe-extensions.ucsd.edu/masst/), that enables the discovery of molecular relationships among accessible public metabolomics and natural product tandem mass spectrometry data (MS/MS).
Defect profiles identification of conducting materials using HTS-SQUID gradiometer with multiple frequencies

This paper is concerned with a quantitative nondestructive evaluation of conducting materials using high temperature superconducting quantum interference devices (HTS-SQUIDs). A mathematical model of the nondestructive evaluation system is described by a three dimensional eddy current model. The forward analyses using the finite element model are implemented for conducting materials with a depth-varying crack. A computational method based on the genetic algorithm is proposed for recovering internal defect profiles with HTS-SQUID data.
United Breaks Guitars

When social media propagate a complaint about poor customer service, an international media event ensues. How do viral videos spread and what can firms do about them? This case dissects an incident in which a disgruntled customer used YouTube and Twitter to spread a music video detailing United's mishandling of his $3500 guitar and the company's subsequent refusal to compensate him. The song was called "United Breaks Guitars. " Within one week it received 3 million views and mainstream news coverage followed, with CNN, The Wall Street Journal, BBC, the CBS Morning Show, and many other print and electronic outlets picking up on the story. The mechanics of viral propagation are uncovered and the limited opportunities for response by the firm are revealed. The case supports the notion of the Internet as an insurgent medium, better at attack than at defense.
New insights into genomic selection through population-based non-parametric prediction methods

Genome-wide selection (GWS) is based on a large number of markers widely distributed throughout the genome. Genome-wide selection provides for the estimation of the effect of each molecular marker on the phenotype, thereby allowing for the capture of all genes affecting the quantitative traits of interest. The main statistical tools applied to GWS are based on random regression or dimensionality reduction methods. In this study a new non-parametric method, called Delta-p was proposed, which was then compared to the Genomic Best Linear Unbiased Predictor (G-BLUP) method. Furthermore, a new selection index combining the genetic values obtained by the G-BLUP and Delta-p, named Delta-p/G-BLUP methods, was proposed. The efficiency of the proposed methods was evaluated through both simulation and real studies. The simulated data consisted of eight scenarios comprising a combination of two levels of heritability, two genetic architectures and two dominance status (absence and complete dominance). Each scenario was simulated ten times. All methods were applied to a real dataset of Asian rice (Oryza sativa) aiming to increase the efficiency of a current breeding program. The methods were compared as regards accuracy of prediction (simulation data) or predictive ability (real dataset), bias and recovery of the true genomic heritability. The results indicated that the proposed Delta-p/G-BLUP index outperformed the other methods in both prediction accuracy and predictive ability.
Tunability of bulk acoustic wave solidly mounted resonators using passive elements: Concept, design and implementation

This paper presents the impedance behavior of the bulk acoustic wave solidly mounted resonators (BAW‐SMR). Also, it shows the effects of the addition of passive elements (L, C) to this type of resonators. In addition, this article presents a tunable BAW‐SMR filter realized in a ladder topology used for the 802.11b/g standard (2.40–2.48 GHz). Mainly, the filter fulfills the requirements for the WLAN 802.11 b/g standard, presenting a measured −3.3 dB of insertion loss, –12.7 dB of return loss and selectivity higher than 33 dB at ±30 MHz of the bandwidth. This tunable BAW‐SMR filter has reduced dimensions (1035 × 1075 μm2). Moreover, we show how to shift the center frequency of this tunable filter toward higher and lower frequencies by adding passive elements. Measured shifts of −1.3% of the center frequency (2.44 GHz) toward lower frequency and +0.6% of the center frequency toward higher frequencies are obtained. © 2011 Wiley Periodicals, Inc.
