Abstract:
Several models of programmed flight have been constructed to perform calculations on flight path optimization in designing tactical and anti-aircraft-guided missiles. The developed models are based on the determination of interrelated programmed values of altitude and the flight path angle depending on the range which have a differential relationship. The combination of flight altitude and flight-path angle programs allows the users to simulate the steady flight of a guided missile to the calculated endpoint using the methods of proportional control.

Abstract:
Programmed cell death (PCD) is an essential and wide-spread physiological process that results in the elimination of cells. Genes required to carry out this process have been identified, and many of these remain the subjects of intense investigation. Here, we describe PCD, its functions, and some of the consequences when it goes awry. We review PCD in the model system, the fruit fly, Drosophila melanogaster, with a particular emphasis on cell death gene discovery resulting from both genetics and genomics-based approaches.

Abstract:
The article outlines the main problems of automatic planning of the behavior of an autonomous unmanned aerial vehicle in unstable air conditions. It is shown that the urgency of the problem is due to the fact that an autonomous unmanned aerial vehicle independently forms and implements its flight route without support from a ground control station. There is therefore a need to develop a method for automatic control of programmed movements associated with the implementation of the route constructed by the problem solver. To solve this problem we propose an approach to regulating the parameters

Abstract:
Abstract This paper investigates stakeholders’ motivations and barriers within emerging Future Flight business models. Aviation is vital for developing economies, and the urgent need for a transition towards more sustainable practices is gaining prominence. Hence, understanding the factors shaping Future Flight technology’s adoption is crucial. Drawing on ten interviews with pioneering Future Flight-related technologists, business leaders, social entrepreneurs, and policymakers, we employed the Technology-Organisation-Environment framework and Transaction Cost Economics theory to analyse critical factors influencing Future Flight business models. We show participants are concerned about sustainable aviation fuel availability and Future Flight technologies’ readiness. We emphasise the importance of technology maturity and commercial viability for successful Future Flight implementation. Smaller start-ups are poised to lead such development because of their nimbleness and sustainability focus. Concurrently, larger companies face challenges transitioning from traditional business models. We identified regulatory frameworks, social acceptance, and public demand as key drivers. Finally, we show how entrepreneurs desire standardised global regulations to support sustainable aviation practices. We offer insights into the complex dynamics of Future Flight adoption, highlighting companies’ need to evaluate their cultural and human resource strategies while emphasising global regulatory standards’ importance – as part of The CoFFEE Project’s (www.coffeefutureflight.com) broader research programme.

Abstract:
Threshold-based flight data recorder analysis techniques have been widely used across the aerospace industry for fault detection and accident prevention. These techniques can detect pre-programmed events but fail to capture unknown patterns in the dataset. This research proposes a machine learning (ML) algorithm to analyze and detect unusual aero engine performance of a turboshaft engine mounted on a single engine rotorcraft. The performance is first modelled from an FDR dataset consisting of hundred flights, using least squares regression (LSR). A technique to scale the model by adding flight data from subsequent flights is thereafter discussed. Spectral Clustering is used for testing and validating the hypothesis derived from the regression model, by employing synthetically generated FDR data for twenty-five flights.

Abstract:
In the mobile robotic systems a precise estimate of the robot pose (Cartesian [x y] position plus orientation angle θ) with the intention of the path planning optimization is essential for the correct performance, on the part of the robots, for tasks that are destined to it, especially when intention is for mobile robot autonomous navigation. This work uses a ToF (Time-of-Flight) of the RF digital signal interacting with beacons for computational triangulation in the way to provide a pose estimative at bi-dimensional indoor environment, where GPS system is out of range. It's a new technology utilization making good use of old ultrasonic ToF methodology that takes advantage of high performance multicore DSP processors to calculate ToF of the order about ns. A mobile robot platform with differential drive and nonholonomic constraints is used as base for state space, plants and measurements models that are used in the simulations and for validation the experiments. After being tested and validated in the simulator, the control system is programmed in the control board memory of the mobile robot or wheelchair. Thus, the use of material is optimized, firstly validating the entire model virtually and afterwards operating the physical implementation of the navigation system.

Full text
Abstract:
A strategic capability of contemporary naval ships is the ability to launch and recover embarked aircraft such as helicopters in a maritime environment. Such operations are enormously challenging due to deck motion, limited landing space, visibility, ship’s superstructure, etc. This places extreme pressure on the pilot, ship’s crew and the platforms alike, making such shipboard operations the most dangerous of all helicopter flight missions. Therefore, the design and integration of equipment, systems and aids to ensure such operations are done as safely as is practicably possible, presents ship builders, aircraft manufacturers, engineers and pilots with some extremely demanding and complex problems. Major naval ship design/build programmes that include an aviation capability, will inevitably need to engage resources across multiple disciplines that include, but not limited to; engineering, design, logistics, administration, procurement, legal, alliance partners and the customer to manage project risks from the outset. This research highlights the need for a holistic/Systems Engineering approach that recognises risks across the wider ship programme, that can only be managed/resolved by cross-discipline collaboration. This paper presents a novel methodology to elicit risks qualitatively and models the relative risk profile of an aviation project throughout the ship programme lifecycle. The use of an enterprise model based on the three ‘P’ element methodology (3PE): Product, Process, People within an environment has been developed. Furthermore, the research outlines a continuous management and visualisation approach that enables a process of dynamic analysis to both reduce and/or mitigate residual risks progressively throughout the project lifecycle to acceptable levels.

Abstract:
Communications and information technologies play an increasingly important role both within and between national critical infrastructures. From the food that we eat to the water that we drink, to the energy that we use across all modes of transportation to the systems that protect us when we travel in those systems; we rely on information infrastructures. These interdependencies will increase rapidly in coming years. For instance, the European SESAR programme and the US NextGen initiative are using computational systems to increase the efficiency and maintain the safety of air traffic management with increasing numbers of flights. Similarly, a range of ‘smart grid’ initiatives depend upon computational infrastructures to coordinate the supply and demand of renewable and conventional power sources. The benefits that are provided by telecommunications and information technologies also creates new vulnerabilities, for instance, it is increasingly difficult for national critical infrastructures to recover and reorganise their service provision in the aftermath of computational failures. It is for these reasons that this chapter proposes a telecoms inclusion principle. This states that it order to assess the resilience of any national critical infrastructure we must consider the failure modes and resilience capabilities of telecommunications infrastructures. A consequence of this principle is that the failure of telecommunications infrastructures must be considered in all contingency plans, in drills and exercises, as well as the recovery strategies that are used to mitigate the consequences of an adverse event.

Full text
Abstract:
Cognitive behaviour therapy for anxiety disorders is a brief psychological treatment (1 to 16 sessions), based on the cognitive model of emotional disorders. Within this model, it is assumed that it is not events per se, but rather people's expectations and interpretations of events, which are responsible for the production of negative emotions such as anxiety, anger, guilt, or sadness. In anxiety, the important interpretations, or cognitions, concern perceived physical or psychosocial danger. In everyday life, many situations are objectively dangerous. In such situations, individuals’ perceptions are often realistic appraisals of the inherent danger. However, Beck argues that in anxiety disorders, patients systematically overestimate the danger inherent in certain situations, bodily sensations, or mental processes. Overestimates of danger can arise from distorted estimates of the likelihood of a feared event, distorted estimates of the severity of the event, and/or distorted estimates of one's coping resources and the availability of rescue factors. Once a stimulus is interpreted as a source of danger, an ‘anxiety programme’ is activated. This is a pattern of responses that is probably inherited from our evolutionary past and originally served to protect us from harm in objectively dangerous primitive environments (such as attack from a predator). The programme includes changes in autonomic arousal as preparation for flight/fight/fainting and increased scanning of the environment for possible sources of danger. In modern life, there are also situations in which these responses are adaptive (such as getting out of the path of a speeding car). However, when, as in anxiety disorders, the danger is more imagined than real, these anxiety responses are largely inappropriate. Instead of serving a useful function, they contribute to a series of vicious circles that tend to maintain or exacerbate the anxiety disorder. Two types of vicious circle are common in anxiety disorders. First, the reflexively elicited somatic and cognitive symptoms of anxiety become further sources of perceived danger. For example, blushing can be taken as an indication that one has made a fool of oneself, and this may lead to further embarrassment and blushing; or a racing heart may be taken as evidence of an impending heart attack and this may produce further anxiety and cardiac symptoms. Second, patients often engage in behavioural and cognitive strategies that are intended to prevent the feared events from occurring. However, because the fears are unrealistic, the main effect of these strategies is to prevent patients from disconfirming their negative beliefs. For example, patients who fear that the unusual and racing thoughts experienced during panic attacks indicate that they are in danger of going mad and often try to control their thoughts and (erroneously) believe that if they had not done so, they would have gone mad. Within cognitive models of anxiety disorders, at least two different levels of disturbed thinking are distinguished. First, negative automatic thoughts are those thoughts or images that are present in specific situations when an individual is anxious. For example, someone concerned about social evaluation might have the negative thought, ‘They think I'm boring’, while talking to a group of acquaintances. Second, dysfunctional assumptions are general beliefs, which individuals hold about the world and themselves which are said to make them prone to interpret specific situations in an excessively negative and dysfunctional fashion. For example, a rule involving an extreme equation of self-worth with social approval (‘Unless I am liked by everyone, I am worthless’) might make an individual particularly likely to interpret silent spells in conversation as an indication that others think one is boring. Cognitive behaviour therapy attempts to treat anxiety disorders by (a) helping patients identify their negative danger-related thoughts and beliefs, and (b) modifying these cognitions and the behavioural and cognitive processes that normally maintain them. A wide range of procedures are used to achieve these aims, including education, discussion of evidence for and against the beliefs, imagery modification, attentional manipulations, exposure to feared stimuli, and numerous other behavioural assignments. Within sessions there is a strong emphasis on experiential work and on working with high affect. Between sessions, patients follow extensive homework assignments. As in cognitive behaviour therapy for other disorders, the general approach is one of collaborative empiricism in which patient and therapist view the patient's fearful thoughts as hypotheses to be critically examined and tested.
