AbstractThe bird strike damage on aircrafts is a widely studied matter [1] with a high economic impact on stakeholders finances. Some authors estimate it in about USD1.2 Billion for nowadays commercial worldwide activity [2], and more than USD937 million in direct and other monetary losses per year just for the United States, as an example of civil aviation industry [3]. The present techniques to face this problem have been previously analyzed in order to decrease the wild life hazards at the airport facilities [4] however nowadays there is a new point of view to prevent this risk at airports that requires an interesting approach in relationship with industrial process improvement examples, such approach lies on preserving the natural life at the airport facilities by developing raptor micro-habitats than change into exclusion areas when the risk of being hunted is recognized by the existing wildlife.Therefore, the main goal of this paper is to share several experiences developed at the Spanish dual airport (military & civilian) of San Javier (Spain), as a case of study in where the mathematics and nonlinear sciences provides the foundations of the ontological knowledge for falconry performance as a Wildlife Control Technique for airport facilities.

Nationally, wildlife-aircraft collisions (wildlife strikes) have been increasing over the past 25 years; denoted in the National Wildlife Strike Database that has been maintained by the Federal Aviation Administration (FAA) since 1990. Increasing wildlife populations and air traffic coupled with quieter, faster aircraft create a significant risk to aviation safety; the cost to the civil aviation industry is an estimated $937 million dollars annually. USDA/APHIS/Wildlife Services (WS) provides technical and direct assistance to over 850 airports and airbases around the United States, including Chicago’s O’Hare International Airport (ORD). At ORD, raptors are one of the most commonly struck bird guild and accounted for at least 25% of damaging strikes from 2010-2013. An Integrated Wildlife Damage Management (IWDM) program is implemented at ORD to reduce the presence of wildlife on the airfield, consequently lowering the risk of wildlife strikes. Professional airport wildlife biologists at ORD concentrate much of their efforts on raptor management due to the high strike risk these birds pose to aircraft on the airfield itself. A variety of techniques are currently used to manage raptor populations at ORD. Concurrently, research is being conducted to evaluate the efficacy of the Red-tailed Hawk relocation program at the airport, as well as to assess their movements within the airfield environment.

Regression Tree Model

Air transport is playing an increasing role in the world economy every year. This is facilitated by technological development and the latest developments in the aviation industry, globalization. This paper provides an overview of artificial neural network training methods for airfare predicting. The articles for 2017-2019 were analyzed in order to determine the model with the most accurate prediction. The researchers conducted research on open data collected by themselves and set themselves the goal of creating a model that would advise a user the best time to buy a ticket when the price would be the lowest. The review of the papers by similar themes revealed that the Bagging Regression Tree model has the highest results with an accuracy of 88% and the random forest method has an accuracy of 87%. Civil aviation plays an important role in the economy of each country. Aviation is the best way to cover long distances in comfort in the shortest time. Airlines offer customers a variety of opportunities to travel both within the country and abroad. The main problem of interaction between airlines and customers is the airfare: the former want to sell more at the higher price, and the latter want to buy cheaper. Therefore, companies use their own private algorithms for dynamic pricing and constantly monitor the market situation, responsive to changes in demand and the actions of competitors. This behavior allows them to achieve a balance between the desires of airlines and customers. Scientists are trying to invent a way to predict airfare so that air travelers can buy them at the lowest price. The results of the work in this area provide general rules for the best purchase. For example, according to the article (Udachny, 2016) thebest day to buy a ticket by expedia.com for a domestic flight on the United States is Sunday, and the best period is 57 days before departure. This article provides an overview of the works, the authors of which compared the models of machine learning. Achievements in this area are limited to direct flights of a certain domestic market (USA, India) and 88% accuracy of the forecast (Tziridis et al., 2017). The Bagging Regression Tree model described in the article (Tziridis et al., 2017) can be considered the best result. This trained model can make predictions based only on two parameters: the number of free cargo and the number of days left before departure and has an accuracy of 88%.

Energy conservation and economic potential of large capacity (∼MWth) solar-assisted water-to-water heat pumps (SAHP) is evaluated for year round low temperature (<100° C) industrial process heating applications at four locations in the United States. The long-term thermal performance of the SAHP system is determined by a recently proposed utilizability method that accounts for the variable coefficient of performance of the SAHP system. The large SAHP system appears to be an attractive energy conservation alternative to fuel oil and electricity for locations with high solar resources and low electricity costs. In all but one location, the SAHP system was clearly superior to the solar only systems, such as flat plate and concentrating collectors, from the point of view of the annualized delivered energy cost. For the ranges of collector area and load temperatures considered in this study, the large SAHP system has clearly superior energy conservation potential at all four locations compared to other alternatives such as fuel oil or electricity. However, the practial suitability of SAHP cycle, as determined by the levelized cost of delivered energy, is unfavorable at all four locations when compared with fuel oil.

Simultaneous Separation

The article examines the possibility of transfer to bipartisan system in Russia. The authors assess the benefits of the two-party system that include first of all the ensuring of actual political competition and authority alternativeness with simultaneous separation of minute non-system forces that may contribute to the country destabilization. The authors analyze the accompanying risks and show that the concept of the two-party system as the catalyst of elite schism is mostly exaggerated. The authors pay separate attention to the experience of bipartisan system implementation in other countries, including the United States. They offer detailed analysis of the generated concept of the bipartisanship crisis and show that this point of view doesn’t quite agree with the current political practice. The authors also examine the foreign experience of the single-party system. They show that the success of the said system is mostly insubstantial, besides many of such systems have altered into more complex structures, while commentators very often use not the actual information but the established myths about this or that country. The authors also offer practical advice regarding the potential technologies of transition to the bipartisan system in Russia.

The Law

Abstract In the review below the author presents a general overview of the selected contemporary legal issues related to the present growth of the aviation industry and the development of aviation technologies. The review is focused on the questions at the intersection of aviation law and personal data protection law. Massive processing of passenger data (Passenger Name Record, PNR) in IT systems is a daily activity for the contemporary aviation industry. Simultaneously, since the mid- 1990s we can observe the rapid growth of personal data protection law as a very new branch of the law. The importance of this new branch of the law for the aviation industry is however still questionable and unclear. This article includes the summary of the author’s own research conducted between 2011 and 2017, in particular his audits in LOT Polish Airlines (June 2011-April 2013) and Lublin Airport (July - September 2013) and the author’s analyses of public information shared by International Civil Aviation Organization (ICAO), International Air Transport Association (IATA), Association of European Airlines (AEA), Civil Aviation Authority (ULC) and (GIODO). The purpose of the author’s research was to determine the applicability of the implementation of technical and organizational measures established by personal data protection law in aviation industry entities.

Lack Of Knowledge

The transfer of some innovative technologies from the laboratory to industrial scale is many times not taken into account in the design and development of some functional materials such as hydrogels to be applied in the biomedical field. There is a lack of knowledge in the scientific field where many aspects of scaling to an industrial process are ignored, and products cannot reach the market. Injectable hydrogels are a good example that we have used in our research to show the different steps needed to follow to get a product in the market based on them. From synthesis and process validation to characterization techniques used and assays performed to ensure the safety and efficacy of the product, following regulation, several well-defined protocols must be adopted. Therefore, this paper summarized all these aspects due to the lack of knowledge that exists about the industrialization of injectable products with the great importance that it entails, and it is intended to serve as a guide on this area to non-initiated scientists. More concretely, in this work, the characteristics and requirements for the development of injectable hydrogels from the laboratory to industrial scale is presented in terms of (i) synthesis techniques employed to obtain injectable hydrogels with tunable desired properties, (ii) the most common characterization techniques to characterize hydrogels, and (iii) the necessary safety and efficacy assays and protocols to industrialize and commercialize injectable hydrogels from the regulatory point of view. Finally, this review also mentioned and explained a real example of the development of a natural hyaluronic acid hydrogel that reached the market as an injectable product.

In 1960 Hanssen and James described to the Institute a system developed and used by the United States Hydrographic Office for selecting the optimum track for transoceanic crossings by applying long-range predictions of winds, waves and currents to a knowledge of how the routed vessel reacts to these variables. The paper (Journal, 13, 253) described how, over a period of two years, an average reduction in travel time of 14 hours was achieved over 1000 optimum routes.In the present papers, presented at an Institute meeting held in London on 19 April, Captain Wepster of the Holland-America Line first of all goes into the benefits which effective ship routing offers the ship operator and then describes the results of the experimental routing programme undertaken by his Company in association with the Royal Netherlands Meteorological Institute. Mr. Verploegh of that Institute then discusses the programme from the forecaster's point of view.

Introduction: Medical errors are a frequent cause of morbidity and mortality in hospitals worldwide. Poor teamwork and communication skills rather than lack of technical knowledge have been identified as a common factor in numerous studies. Objective: To promote a safer medical practice through the adoption of Crew Resource Management (CRM) procedures directly adapted from the aviation industry for the first time in Argentina. Methods: Starting in 2009 we organized a hybrid team of two physicians/amateur aviators and two expert airline pilots with a significant background on safety analysis and CRM training . The setting for the initial experience was a teaching hospital with high volume cardiovascular and organ transplantation departments. CRM training has been offered at least once a year in a non compulsory manner to the entire spectrum of healthcare personnel, including medical and nursing students. Courses are structured in two day sessions divided in several chapters and workshops: Introduction, statistics, leadership, communication skills, and avoidance of risky behaviors. Slides, full text articles and reports are available for permanent consultation by personnel along with discussion forums at the Moodle based site of the program. Results: Satisfaction levels among attendees has consistently averaged 92%. Following training, briefings and debriefings have been implemented as standard procedures along with checklists both at Intensive Care, Operating Rooms and General Ward. No wrong side or wrong patient interventions have been reported over 3 years, while in 1/9500 surgical procedures a misidentification of a patient occurred with successful detection at the second crossed check on admission to the OR. Overdosing was reported in 1 every 4960 admissions, none fatal or disabling. Conclusions: Choosing a hybrid team of physicians and airline pilots rather than physicians or nurses alone as facilitators was a key factor to spark interest in teamwork factors and to avoid fear of punishment following reports. Despite cultural differences, CRM can be as feasible and successful in a Latin American hospital environment as previously shown in several centers in the United States.
