Abstract:
As one of the most outstanding Japanese authors, Haruki Murakami always comes up with excellent ideas of surrealistic stories. The Postmodern condition is evident in most of Murakami’s novels. A sense of alienation of character and world is evident by a language medium invented to form a kind of rhythmic syntax structure which complements the illustration of the main characters’ subconscious fears and paranoia in the course of his exploration of a seemingly chaotic world. His portrayal of characters is unique and significant that expresses the dichotomy of characters who fight between reality and fantasy. Nevertheless, their ambition to be free from the structures that bound them do not always come true. Some of them left their symbolic mechanism to enter another one. In the end, the characters cannot be the Other; as long as they are still in the clutches of a particular token device they would only be able to be the other. His Characters explore themselves in search of meaning of their existence. His characters often utter speeches which directly contradict their subsequent actions.They are male, middle-aged, leading aimless existences. They enjoy preparing and eating such western foods as spaghetti; they love American pop culture, particularly music of the 1960s and 1970s; and they are hedonistic and idle. They either engage in casual love affairs or fantasize about having them. His novels like After dark(2004) and The Wind-Up Bird Chronicle (1994) is postmodern works by the coexistence of the surreal scenes.

Abstract:
Wind as a clean and renewable energy source has been used by humans for centuries. However, in recent years with the increase in the number and size of wind turbines, their impact on avifauna has become worrisome. Researchers estimated that in the U.S. up to 500,000 birds die annually due to collisions with wind turbines. This article proposes a system for mitigating bird mortality around wind farms. The solution is based on a stereo-vision system embedded in distributed computing and IoT paradigms. After a bird’s detection in a defined zone, the decision-making system activates a collision avoidance routine composed of light and sound deterrents and the turbine stopping procedure. The development process applies a User-Driven Design approach along with the process of component selection and heuristic adjustment. This proposal includes a bird detection method and localization procedure. The bird identification is carried out using artificial intelligence algorithms. Validation tests with a fixed-wing drone and verifying observations by ornithologists proved the system’s desired reliability of detecting a bird with wingspan over 1.5 m from at least 300 m. Moreover, the suitability of the system to classify the size of the detected bird into one of three wingspan categories, small, medium and large, was confirmed.

Abstract:
In this essay Murakami Haruki’s novel The Wind Up Bird Chronicle was analysed from the perspective of Mikhail Bakhtin’s theory of the chronotope. The aim was to explore the concept of time and space as presented in the novel. In particular, the analysis focused on how Bakhtin’s chronotopes can be applied to The Wind Up Bird Chronicle, how the chronotopes can enhance our understanding of the novel, and finally how the chronotope theory can be applied to the concept of ‘magic realism’ that is often used to describe Murakami’s authorship. Four chronotopes, presented by Bachtin, were selected and applied to the novel: every-day life, the road, crisis and the castle. The concept of the chronotope allows analysis of how time and space work together in literature and how they form patterns of correlation in the sujet. Results showed that the four chronotopes were found in the novel, and that they also interacted with each other. The chronotope of everyday-life was apparent throughout the novel, and the narrator was under its control. The narrator also seemed to create every-day life out of the chronotopes of the road and crisis by re-living the crises in the road. These three chronotopes seemed inseparable in The Wind Up Bird Chronicle. Finally, the fourth chronotope, the castle, illustrated how a concrete room in the novel, a house, became a part of time and space through a character who, by his presence, gave the impression of slowing down time. When this character disappeared, time made its way through space, making the chronotope of the castle visible. The essay concludes that the chronotope theory was a relevant way to analyse The Wind Up Chronicle as it provided a concept of how time and space appeared together in a novel where time and space is always present. The analysis helped creating a way of understanding the patterns in the novel, which were not always clear, thereby also increasing the understanding of The Wind Up Bird Chronicle.

“The Wind-up Bird Chronicle” is a turning point of Haruki Murakami’s works. It is the first Murakami novel that brings the historical events during Imperial Japan period in. Therefore, there will be three subjects in this thesis. The first subject is “powerful people’s Japan”. The main target of this subject will be Wataya Family, the representive example of powerful people in “The Wind-up Bird Chronicle”. Wataya Family also has a connection to those historical events. The second subject is “soldiers and civilians’ Japan”. The main target of this subject will be Mr. Honda, Lieutenant Mamiya, and Nutmeg Akasaka. These characters’ experiences during wartime period will be focused in this subject. The third subject is “the historical background”. Researching of the wartime period those character experienced is a way to consider Murakami’s thought. Then, the time Murakami wrote “The Wind-up Bird Chronicle” will be focused on. Through these three subjects in this thesis, the author hopes to approach what Murakami wants to tell readers through the ecriture of Imperial Japan.

The main protagonist in Haruki Murakami’s earlier works are often not given a full name or any background information, such as relatives or even particularly close friends. As such, the character is not tied to any group of people– a befitting expression of individualism. And yet, during the 90''s, when South of the Border, West of the Sun and The Wind-Up Bird Chronicle were published, this type of setting of characters who had no background and seemingly no ties to society were replaced by that the main protagonist started to be given a name with Kanji characters, a family, and a personal history. In The Wind-Up Bird Chronicle, descriptions of the Battle of Khalkhin Gol were abundant, and in 1Q84, mentions of the Aum Shinrikyo, a Japanese cult, can be seen. The character setting transition and the incorporation of actual history and social events into his works reveal a change in the attitude of Murakami from being one of ‘social detachment’ to one of ‘social commitment’. What can be seen as well in these socially relevant works is the increase in the proportion that talks about ''the system''. This study has therefore chosen The Wind-Up Bird Chronicle and 1Q84, both stories set in 1984, to analyze primarily through the novel text with the secondary supplement of studies in Sociology and Psychology, in order to investigate the System described in these two works, as well as its relationship to the characters that represents individualism. Investigation of The Wind-Up Bird Chronicle is focused on the sections that describe historical events, exploring collectivism, the power structure, and patriarchy – ideas demonstrated by the nation, the largest of social systems, while the investigation of 1Q84, which heavily describes enclosed systems, analyzes ideas of mind control and collectivism. Furthermore, analysis is conducted on how the system repression influences the individual, and how the individual opposes this influence. The purpose of this research is to understand the image of the Japanese society, in other words, its modern social problems, as reflected in Murakami novels through his writing, and to investigate whether these social problems cause any changes in the author’s viewpoint toward the System.

There are three issues to be studied in this thesis. In Chapter 1, this thesis reviews the advance study in order to confirm the development and Transition in Haruki Murakami Literature. In Chapter 2 to Chapter 4, I study the Realty in “Dance, Dance, Dance”, “South of the Border, West of the Sun”, and “The Wind-Up Bird Chronicle” in Haruki Murakami Literature. To study the Realty in “Dance, Dance, Dance”, “South of the Border, West of the Sun”, and “The Wind-Up Bird Chronicle” is the first issue. According to my study, there is not only one Realty in Haruki Murakami Literature. Specifically speaking, the character make the relationship with others to let himself link with the Reality. The development of the Reality in Haruki Murakami Literature is mentioned in the second issue. We can figure out some changes of the Reality since “Dance, Dance, Dance”. Before “Dance, Dance, Dance”, the Reality is the real word. However, after “Dance, Dance, Dance”, the Reality should not be understood like a space. Especially, since “The Wind-Up Bird Chronicle”, the characters try to heal themselves by the Reality which is unreality. The relationship between the Reality and Haruki Murakami is studied in the third issue. Since 1986 to 1995, Haruki Murakami worked in the EU and USA. He published “Dance, Dance, Dance”, “South of the Border, West of the Sun”, and “The Wind-Up Bird Chronicle” during this 10 years. However, at the same period, Japan was force to face Economic bubble, the Great Hanshin earthquake and Tokyo subway sarin attack. Actually, the transformation of Haruki Murakami proves the change for Japan.

Abstract As a well-loved modern writer in his native Japan, Haruki Murakami’s literatures also gain widespread popularity internationally. Compared to substantial researches focusing on his single novel, the topic on thinking shift of certain novels during a period are relatively fewer. According to Hear the Wind Sing, Pinball, 1973 and A Wild Sheep Chase, one of the most noticeable features in Haruki Murakami’s literatures is main characters’ “closure ”. Main characters always keep a certain distance from social interaction world, enjoying themselves in their own closed world. This closure lifestyle not only associates interpersonal isolation, but also reflects current condition nowadays. However, this closure feature seems to have turned in his subsequent novels after Norwegian Wood. With the emergence of someone who main characters want to interact, they show shift from closure mindset to living with others in the real world. This study focused on Norwegian Wood, South of the Border, West of the Sun, and The Wind-Up Bird Chronicle. Then, illustrated characters’ anxiety and mental change based on the examples of common plots’ repetitiveness, physical change inside the novels. When main characters’ mindset change, the study also explored issues “how they try to find ways out of closed world, further seeking possibilities in the real world” and “other characters’ survival modes”. After these analyses, the study concludes main characters’ growth from self-centeredness to fighting for others. Meanwhile, describes how to overcome life''s unexpected problems, inevitable difficulties in communication during interpersonal interaction, as well as the survival mode lived with others.

Abstract:
Why did I choose to end this book with the Gila River Indian Community’s effort to win back its water? Because it is a parable about how democracy and its courts can not only serve but also be served by the quest for sustainability. The GRIC water settlement brought a long struggle for environmental justice to a triumphant conclusion. Delivering justice meant that a large portion of the region’s available resources would be sequestered from the growth machine. Instead of supplying a new generation of low-density tract housing, the water could now be used to produce healthy, local food for the area population, and, if nonindustrial agriculture prevailed, the result would be a double win for carbon reduction. Surely, this is how a green polity ought to act, redressing the claims of those who have been aggrieved, and doing it in a way that extends long-term benefits for all. If all responses to environmental injustice were able to follow suit, it would be a welcome model for moving forward. Even if the Gila River example is unlikely to be replicated in other places, its guiding spirit is a sound one. What if the key to sustainability lies in innovating healthy pathways out of poverty for populations at risk, rather than marketing green gizmos to those who already have many options to choose from? These are not mutually exclusive options, of course, but the lessons I took away from my research convinced me of the pressing need for clear alternatives to the eco-apartheid syndrome that afflicts Phoenix and so many other cities. Building a low-carbon economy by targeting only the LOHAS demographic (Lifestyles of Health and Sustainability, the upmarket segment of 40 million, or 20 percent of consumers, nationally) will end up doing little more than adding a green gloss to patterns of chronic inequality. Likewise, placing all of our faith in clean-tech fixes will cede too much decision making to a closed circle of experts who, regardless of their technical prowess, will have no power to prevent the uneven application of their solutions.

Abstract:
Fantastic beings proliferate in pre-Han and Han literature and are represented in a variety of forms up through the Six Dynasties period. They pose some problems of identification and classification for both ancient and modern scholars. Thus different sources specify various bird or animal forms for Feilian, the Wind Earl. Chiyou, another pre-Han rebel, now appears as a warlike monster leading a troupe of storm spirits. These thunders of Southeast China do have specific names on one Northern Wei epitaph tablet of 522. Elsewhere auspicious or apotropaic inscriptions on paired messenger birds and evil-averting tomb protectors are often interpreted as names even though archaeological evidence may suggest otherwise. The Chinese “unicorn,” a creature that resists classification, comes to resemble its mate, the “lion.” In general, the forms and functions of mythical beings are established in this period.

Abstract:
Abstract Subsea export power transmission cables for offshore wind farms are being installed more extensively year-on-year due to the increasing demands for power output from renewable sources. With the increasing number of installations, the number of cable failures during installation has increased. One failure mode involves the temporary or permanent radial deformation of armour wires otherwise known as armour wire bird caging which occurs from a combination of twist, bending and compression loads which build up in a cable. This failure mode can lead to significant remediation costs and schedule delays for projects affected. In this paper, the authors present a method for predicting armour wire bird caging for generic installation configurations based on a review of the root causes from several historical bird caging failure instances. Various numerical models and analyses which simulate the installation conditions are described. The models simulate key response mechanisms including bending-induced twist and inter-layer separation within a cable. Cable loading conditions are compared with cable bird caging limits and the parameters which influence the onset of bird caging are identified. Based on a range of sensitivity analyses, handling curves to assist with installation are developed and a full-scale test validation programme is proposed. This work was performed for a project which received financial and technical support from The Carbon Trust’s Offshore Wind Accelerator (OWA), a collaborative R&D programme funded by nine leading offshore wind developers (EnBW, Equinor, Innogy, Ørsted, RWE, SPR, Shell, SSE, Vattenfall) and the Scottish Government.

Abstract:
The continuing growth of Unmanned Aerial Vehicle (UAV) use in reconnaissance and surveillance has led to an increased demand for novel flight systems that improve vehicle flight capabilities in cluttered and turbulent environments. Bio-inspired wings with feather-like flaps have been proposed to enable bird-scale UAVs to fly robustly in such environments. This paper presents the development of a three-dimensional iterative constant strength doublet Adaptive Panel Method (APM) for calculating the flight characteristics of a multi-body wing operating in any of its possible configurations. A three-dimensional wake relaxation algorithm is incorporated into the model, which enables accurate wake shapes and down-stream roll-up for each flap configuration to be derived. Wake modeling is shown to improve the accuracy of the pressure distributions induced by the wake-body interactions. The flight coefficients calculated using this method are validated by experimental values obtained from a low speed suction wind tunnel operating at a Reynolds number of 300,000. Finally, it is shown that the APM aids in determining accurate surface loads for the preliminary design process of multi-body wings.

Abstract:
Early forecasting of bird migration patterns has important application for example in reducing avian biodiversity loss. An estimated 100 million to 1 billion birds are known to die yearly during migration due to fatal collisions with human made infrastructures such as buildings, high tension lines, wind turbines and aircrafts thus raising a huge concern for conservationists. Building models that can forecast accurate migration patterns is therefore important to enable the optimal management of these critical infrastructures with the sole aim of reducing biodiversity loss. While previous works have largely focused on the task of forecasting migration intensities and the onset of just one migration state, predicting several migration states at even finer granularity is more useful towards optimally managing the infrastructures that causes these deaths. In this work, we consider the task of forecasting migration patterns of the popular Turkey Vulture (Cathartes aura) collected with the aid of satellite telemetry for multiple years at a resolution of one hour. We use a deep Bidirectional-GRU recurrent neural network augmented with an auxiliary task where the state information of one layer is used to initialise the other. Empirical results on a variety of experiments with our approach show we can accurately forecast migration up to one week in advance performing better than a variety of baselines.

Abstract:
Even though Unmanned Aerial Vehicles (UAVs) operating at low Reynolds numbers are becoming common, their performance and maneuverability are still greatly limited due to aerodynamic phenomena such as stall and flow separation. Birds mitigate these limitations by adapting their wings and feather shapes during flight. Equipped with a set of small feathers, known as the alula, located near the leading edge and covering 5% to 20% of the span, bird wings can sustain the lift necessary to fly at low velocities and high angles of attack. This paper presents the effect on lift generation of different placements of a Leading-Edge Alula-inpsired Device (LEAD) along the span of a moderate aspect-ratio wing. The device is modeled after the alula on a bird, and it increases the capability of a wing to maintain higher pressure gradients by modifying the near-wall flow close to the leading-edge. It also generates tip vortices that modify the turbulence on the upper-surface of the wing, delaying flow separation. The effect of the LEAD can be compared to traditional slats or vortex generators on two-dimensional wings. For finite wings, on the other hand, the effect depends on the interaction between the LEADs tip vortices and those from the main structure. Wind tunnel experiments were conducted on a cambered wing at post-stall and deep-stall angles of attack at low Reynolds numbers of 100,000 and 135,000. To quantify the aerodynamic effect of the device, the lift generated by the wing with and without the LEAD were measured using a 6-axis force and torque transducer, and the resulting lift coefficients were compared. Results show that the location of the LEAD yielding the highest lift enhancement was 50% semi-span away from the wing root. Lift improvements of up to 32% for post stall and 37% for deep stall were obtained at this location, demonstrating that the three-dimensional effects of the LEAD are important. The lift enhancement was also more prominent on a finite moderate aspect-ratio wing (3D) than on an airfoil (2D), confirming that the LEAD is a three-dimensional device. Identifying the configurations and deployment parameters that improve lift generation the most is needed to design an adaptive LEAD that can be implemented on a UAV wing for increased mission-adaptability.

Abstract:
A low-cost rigid foam-based concentrator technology development program was funded by the DOE SunShot Initiative to meet installed cost goals of $75/m2 vs. current costs of ∼ $200–250/m2. Phase 1 of the project focused on design trades and cost analyses leading to a cost-optimized self-powered autonomous tracking heliostat concept with a mirror surface area in the 100m2 range. In Phase 2 30-year accelerated testing of the mirror modules based on ReflecTec film with 94% specular reflectivity bonded on composite foam substrate were initiated and completed in Phase 3. The tests with 15 coupons showed optical performance degradation of less than 5% in specular reflectance following 30-year equivalent UV testing and other abuse testing such as acid rain, bird dropping, thermal cycling, etc. A small scale prototype (3m×2m) heliostat design based on modular truss elements with removable mirror modules was developed in detail. In this phase components such as the dual-axis actuators were sized and selected based on wind load requirements and pointing accuracy demands were completed. Finite Element analyses for the mechanical structure with mirror modules were performed using three separate commercial codes — ANSYS, COMSOL and SolidWorks to validate the optical errors induced by wind loads on the structure up to 35 mph. Results indicated that the RMS deflections contributed to less than 0.4 mrad pointing error. Dynamic response of the heliostat indicated that the first 5 eigenmodes were in the 17–20 Hz range. The individual structure elements such as the trusses and c-rails were fabricated locally and assembled with the mirror facets in the lab for initial fit check and testing. The nine mirror facet surface errors were characterized using photogrammetry and verified using Reverse Hartmann techniques and showed to be in the order of 1 mrad or less. A three-level controller (main, gateway and heliostat) was architected and built. Tracking of the sun is done using NREL’s Sun Tracking Algorithm implemented in the gateway controller. Target-pointing vectors are calculated for each heliostat and conveyed wirelessly to the individual heliostat controllers for actuating the azimuth and elevation motors. The power subsystem consisting of solar panels and a battery provide 24V for the actuators and controller boards. The system was sized to provide adequate power for a period of 5hrs of operation when power is not available. Initial calibration will be performed with on-site camera tracking the sun’s image on a target located approximately 52m from the heliostat. Testing of the heliostat pointing under calm and windy conditions will be done to demonstrate overall performance that meet DOE targets of 4 mrad under 27mph winds. Commercialization efforts are underway to transition the design to the commercial sector. The project is well on its way to approaching overall cost targets and current estimates are approximately $90–110/m2 and lower costs can be achieved with alternates to the film we have identified.
