Abstract:
A balanced regular calorie intake along with a good eating rules is an important factor to fullfill a healthy lifestyle and diet. Both are the main keys to preventing non-communicable diseases (NCDs) which are the largest contributors to world deaths. The effects produced through dietary regulation and calorie intake ideally will affect to the long term, so that consistency and adequate supporting media are needed. Judging from the time scale, action is needed since in, Early action is needed, especially for students who are in the transition period to maturity and independence. Technological developments in the digital era can be used to produce problem solutions ranging from fundamental aspects. Students themselves are familiar with the concept of the calorie tracker application (Craker) even though the majority have never used it. The purpose of this paper is to design the Craker application as a form of solution to regulate diet and calorie intake by applying the theory of human and computer interaction. The result of making this application is to monitor the number of calories consumed by knowing the number of calories in and out so that it is balanced according to the recommendations given based on the user’s profile, for the calorie tracker application we can divide it into three types of calorie tracker applications: web, mobile, and physical.

Abstract:
This paper analyses the human bodies as a site of both aesthetics as well as politics in post-human turn in the novel Oryx and Crake by Margaret Atwood. Questions related to what is a body, who controls it, and what relation does it have to morality at techno-science culture share a negotiation between machine and morality. After the advent of popular culture, the concept of body as cogent and self-bounded entity is blurry one as the discourse of ‘what is a beautiful body’ reflects a growing concern with different approaches of body aesthetics. As seen the novel, Oryx and Crake by Margaret Atwood, we see Crakers— the genetically modified humans as an outcome of Crake’s aesthetics and politics. Jimmy’s father’s involvement in Pigoon Projects designed with the intention of providing human organs for transplantation and Crake’s involvement in creating Crakers—whom Crake had programmed to die at 30 open a new avenue for discussion regarding human identity. Such dimension of body aesthetics is precarious leading to ethical question as progress in science does not only enhance body, it also poses a threat to humanity in entirety. This research is qualitative and interpretive in nature. So, as a researcher, I have brought theoretical insights related to trans-humanism and post-humanism developed by Fukuyama, Braidotti. In the paper, I conclude that though new version of body aesthetics poses a threat to the world itself, it helps to understand how humans have co-evolved with other companion species. Thus, it contributes on the discussion of literary engagement and literary understanding of post humanism.

Abstract:
Furnace 15-F-102 menggunakan tipe silinder vertical, furnace tipe ini memeasukkan udara secara alami atau sering disebut natural draft. Furnace 15-F-102 menggunakan bahan bakar fuel gas. Salah satu faktor yang mempengaruhi biaya operasi kilang yang cukup besar merupakan bahan bakar. Dengan demikian pemakaian bahan bakar selalu menjadi perhatian utama karena ada kemungkinan tidak effisiennya dalam proses pembakaran. Kinerja dari furnace dapat dilihat pada jumlah bahan bakar yang digunakan dan panas yang hilang ke lingkungan, baik panas yang hilang melalui gas asap maupun yang keluar melalui dinding furnace. Kinerja dari furnace yang optimal ditandai dengan rendahnya suhu gas asap, pemakain bahan bakar yang cukup dan exess air. Namun yang sering terjadi dilapangan adalah kekurang tepatannya dalam mengatur excess air sehingga menyebabkan rendahnya kinerja furnace dengan data yang di peroleh. Penulis mencoba untuk melakukan optimasi furnace 15-F-102 di unit RCU PT. X yang ditinjau melalui kebutuhan udara pembakaran dengan harapan kinerja dari furnace 15-F-102 dapat ditingkatkan. Metode yang digunakan oleh penulis untuk mengetahui udara pembakaran yang optimum dengan menghitung neraca panas furnace 15-F-102 dengan metode trial and error, yang kemudian melakukan simulasi udara pembakaran sehingga kerugian panas yang di dapatkan semakin kecil dengan dasar acuan exess air optimum, dan melakukan perhitungan energi yang dapat di hemat. Dari simulasi trial and error didapatkan exess air optimal sebesar 6%. Dengan menggunakan exess air 6% menghasilkan penghematan energi sebesar 337192074,5 Kcal/hr. Dan di dapatkan effisiensi alat sebelum dilakukan optimasi sebesar 81%, setelah dilakukan optimasi sebesar 84%. Setelah di didapatkan nilai effisiensi dapatkan di cari biaya operasi sebelum dilakukan optimasi sebesar Rp. 163.807.872.865,00 pertahun, dan biaya operasi setelah dilakukan optimasi sebesar Rp. 146.900.408.013,00 pertahun, dengan demikian didapatkan penghematan biaya operasi sebesar Rp.16.907.464.851,00 per tahun.

Abstract:
As a dystopia, Margaret Atwood’s novel Oryx and Crake speculates the looming consequences of scientific inventions and technologies manifested in the destruction of natural equilibrium and posthuman complexities. Homo sapiens' unlimited desires and aspirations for enhancement and excellence have driven humans to enact the Creator. Crake, almost a mad scientist in the novel, creates the Crakers — genetically modified humans. To analyze this life force, the paper uses theoretical insights of humanists like Giannozzo Manetti, Rene Descartes and Friedrich Nietzsche regarding their celebration of human exceptionalism, reason, and free will. But, to counter-argue transgression in the pretext of progress, the paper also uses Donna Haraway’s concept of inter-speciesism and Rosi Braidotti’s critical posthumanism. They promote interdependence, critical review of the past and abstinence to address the posthuman crises and existential dilemmas. The enhanced Crakers are immune to starvation and ordinary diseases, devoid of art, imagination and creativity; but ironically feed on grass and their own excrement, and lack the essence of being human. They challenge Crake's genome project by transcending the lab-limitations but adapting to natural evolution. Hence, this paper examines Atwood's speculation of how modern science and technology distorts the symbiosis and disfigures the humans resulting in unwanted negotiations for survival. A post-human homofaber, Crake tries to resolve the existential crisis by eliminating the Bastion of humanity itself but ironically dehumanizes the human. The question is how far will humanity overrule nature? Who is accountable to repair the earth? Thus, this paper enables a thought exercise to retrospect on human insensibility and undergo abstinence of desires and luxury to save the future of this planet and lives from facing the impending apocalypse, as shown in the novel.

Abstract:
One attempt to create a processed product of fishery products in the form of finished goods which main raw material are fishery products is by processing it into crackers. Crackers are generally made from tapioca flour as a source of starch with the addition of spices and water which have a low nutrient content. Addition of nutritional crackers can be done by adding fish meat. While on the other hand, the type of fish as the main raw material for making fish crackers greatly influences the color, texture and taste of fish crackers. As in the case with squid crackers which have distinctive taste and performance when compared to other fish crackers. To see the potential of the squid cracker business, it is necessary to conduct research to see whether the processing of squid into squid crackers is able to provide increased income or in other words whether the squid cracker business is feasible or not and how much added value from processing squid to squid crackers. This study aims to look at the feasibility of squid cracker business in terms of financial aspects and to determine the amount of added value obtained from processing squid into squid crackers. The research showed that the development of a squid cracker business was feasible and prospective to be carried out.

Abstract:
The application of quality and packaging to the cracker business in Lumpatan Sekayu Village is the title or topic of the Community Service Team. Providing counseling in the field of marketing management that specializes in quality and packaging of crackers. The implementation of this community service is by means of direct counseling to the cracker business owner and their workers. The goal is that cracker-making businesses can increase their production as a result of increased sales. The quality and packaging of the crackers has not been the concern of this cracker business maker. Several findings by the Community Service Team concluded in the report, 1). so far they have not considered the quality and packaging of the crackers. 2). The use of traditional means of production and drying, cracker size is not standard. 3). Do not have a business, health and halal permit from the relevant government agency. 4). The local government still lacks attention to cracker entrepreneurs, which are a household industry involving the workforce of local housewives. The Community Service Team after providing counseling will monitor and guide, so that these cracker processors carry it out. The team will provide a way out or a solution if they find a problem. The ultimate goal of community service is to improve the welfare of the owner and maker of crackers as well as the community in Lumpatan Sekayu Village.

Abstract:
AbstractFood and energy intake can be effectively lowered by changing food properties, but little is known whether modifying food shape is sufficient to influence intake. This study investigated the influence of cracker shape and cheese viscosity on ad libitum intake of cracker–cheese combinations. Forty-four participants (thirteen males, 23 (sd 3) years, BMI 21 (sd 2) kg/m2) participated in four late afternoon snack sessions (2 × 2 randomised crossover design). Iso-energetic crackers were baked into flat squares and finger-shape cylindrical sticks and combined with a cheese dip varying in viscosity. Approximately eighty crackers and 500 g cheese dip were served in separate large bowls. Participants consumed crackers with cheese dip ad libitum while watching a movie of 30 min. Dipping behaviour and oral processing behaviour were measured simultaneously by hidden balances under the cheese bowls and video recordings. Cracker intake (28 (sem 1) crackers) of cracker–cheese combinations was not influenced by cracker shape. Cheese intake of cracker–cheese combinations was 15 % higher for flat-squared than finger-shape crackers (131 kJ, P = 0·016), as a larger amount of cheese was scooped with flat-squared crackers (2·9 (sem 0·2) v. 2·3 (sem 0·1) g cheese per dip, P < 0·001) and showed higher eating rate and energy intake rate (P < 0·001). Eating rate over snacking time decreased by reducing bite frequency (P < 0·001) while cheese dip size remained fairly constant (P = 0·12). Larger energy intake from condiments was facilitated by increased cracker surface, and this did not trigger earlier satiation. Changing food carrier surface may be a promising approach to moderate energy intake of often high energy dense condiments, sauces and toppings.

Abstract:
Abstract Crater counting is a method which allows us to estimate the surface ages of the planetary bodies, from which the sampling and sample delivery to laboratories on Earth are difficult or impossible. Because the number of craters on a surface unit increases over the time the surface has been exposed to space, old, geologically stable units have more craters than young and active units. When the crater production rate as a function of time is known, the absolute age of the surface unit can be determined based on its crater density. The purpose of this thesis is to investigate the role of small impact craters in crater counts to find out how modern very high-resolution space images can be utilized in age determination of planetary surfaces. The thesis focuses on how reliable crater count based datings are, if only small craters and counting areas are used in age determination. The research is carried out by utilizing crater counts on the outflow channels of Dao, Niger, Harmakhis and Reull Valles, which all are located in the eastern rim region of the Hellas impact basin, on the southern hemisphere of Mars. Crater counts are performed mainly based on the images of ConTeXt Imager (CTX) and High Resolution Imaging Science Experiment (HiRISE) aboard Mars Reconnaissance Orbiter (MRO). The results show that small craters are a very valuable tool to get information about the surface age. Instead of the size-range of counted craters, or the size of counting areas, results are dependent on the variability and scale of the surface modification history. The more variable or larger scale the modification history is, the larger surface area and wider crater diameter range are typically needed to achieve comprehensive age estimations. The crater counts on the eastern Hellas outflow channels support the earlier theories according to which the valles formed during a relatively short time interval, ~ 3.4–3.7 Ga ago. The existence of terrace structures and smaller tributary channels indicate that the outflow channels were filled by several pulses of liquids. The major fluvial activity ended no later than ~ 0.8–1.9 Ga ago, and it was probably controlled by the activity of nearby highland volcanoes. Soon after the declined fluvial activity, the outflow channels were covered by ice-rich deposits. The major reason for this was probably the changed climatic conditions, although in places e.g. impact cratering seems to have contributed to the emplacement of the deposits. The region as a whole was also resurfaced several times because of changes in local climate conditions. The most significant of the resurfacing processes seem to be the episodes of thin ice-rich mantling deposits, the most recent of which dominated the regional modification less than 10 Ma ago. In addition, the region has experienced eolian activity during the last 1 Ma

Abstract:
Cranes are often the most conspicuous machines on a construction site. This is due to their large size, in addition to the important role they have in transporting heavy payloads vertically and horizontally. There are two major families of construction cranes: tower cranes and mobile cranes. Mobile cranes that are mounted on tracks are a subgroup referred to as ``crawler cranes''. Crawler cranes are widely used on construction sites, and are a backbone of the United States construction industry, thus a detailed study of these cranes' behavior is essential. This research studies the tip-over stability of crawler cranes in heavy-lifting applications. Two major applications are discussed: crawler cranes using movable counterweights and crawler cranes in tandem lifting.

Abstract:
This PhD thesis has been realized within the project of STC/SIMBIOSYS, the stereo channel composing the imaging system on board of the BepiColombo mission to Mercury and providing the global mapping in stereo mode of the Hermean surface. As the aim of this work is supporting the definition of the scientific requirements of STC, the impact craters have been recognized as the surface structure to be investigated, being the most important and common landform of any planetary body with a solid surface, but meanwhile far to be yet completely understood. This thesis addresses to explore the importance of impact crater structure as a tool in investigating a variety of aspects of planetary bodies, whose remote sensing data is the only available information. Earth as well can take advantage from studying such a rarely occurring, complicated and highly dynamic process, as the combining effects of erosion, tectonics and volcanism can hide impact structures. The first theme turns to impact craters not as an individual entity, but as a population of features on planetary surfaces, in particular Mercury. The cratering records, being the result of a long–repeated meteorite bombardment history, can be used to infer surface age after the application of a chronological model to statistical analysis. The data recently acquired by the MESSENGER mission during its three flybys with this planet were the starting point to study two new basins, i.e. Raditladi and Rachmaninoff. The MPF chronological model has been adopted to derive the crater retention age for these basins, whose impact events turned out to occur well after the LHB, posing some puzzles to the current impactor sources in the inner Solar System. In addition, Rachmaninoff interior plains could be emplaced in a very recent period (360 Ma ago), suggesting a long–lasting volcanism up to recent time, and hence a revision to our current knowledge on the thermal state of the planet is proposed The second theme of my thesis addresses the investigation of the impact formation process. The current understanding of impact cratering as a whole has come from a suite of experimental, morphological, analytical and numerical studies. However, shocks codes represent one of the only feasible methods for studying impact craters, as they can simulate a large span of conditions beyond the reach of experiments, in addition to analyze the individual effect of any parameters acting during the impact event. I have used iSALE shock code to simulate two craters, coming from a completely different environment, the Earth and one asteroid, recently observed by a space mission. In the first case, the knowledge of the surrounding area where the structure is located allowed to study in detail the impact crater collapse mechanism that origins a large crater. On the other hand, the good relatively knowledge of the formation of a simple crater allowed to investigate the composition and the structure of the asteroid. In both cases, the numerical modelling of the impact process has demonstrated to be a powerful tool to deepen our comprehension on the Solar System.
Questa tesi di dottorato è stata realizzata nell’ambito del progetto di STC/SIMBIOSYS, il canale stereo appartenente al sistema di imaging che a bordo della missione spaziale BepiColombo avrà l’obiettivo di fornire la mappatura globale della superficie di Mercurio in modalità stereo. Poiché lo scopo di questa tesi è di supportare la definizione dei requisiti scientifici della stereo camera, lo studio dei crateri da impatto è stato selezionato come argomento fondamentale. I crateri da impatto sono infatti la più importante e più diffusa morfologia su qualsiasi corpo planetario dotato di una superficie solida, ma allo stesso tempo non ancora completamente compresi. Questa tesi vuole esplorare l’importanza dei crateri da impatto come tool nell’investigazione di una varietà di aspetti riguardanti i corpi planetari, dei quali si hanno a disposizione solo un numero esiguo di informazioni. Tuttavia, anche nel caso della Terra, per la quale si possiede una grande quantità di dati, lo studio di questo processo altamente dinamico può portare ad una migliore conoscenza del nostro pianeta e delle forze che tutt’ora lo modellano. Il primo tema di questa tesi riguarda lo studio dei crateri da impatto non come un’entità singola, ma una popolazione di oggetti presenti sulle superfici planetarie, in particolare quella di Mercurio. La craterizzazione su di una superficie è il risultato di una lunga storia di bombardamento meteoritico, e può essere quindi usato per derivare l’età di quella superficie, se si applica un modello cronologico basato sull’analisi statistica dei crateri. I dati recentemente acquisiti dalla missione MESSENGER durante i suoi tre flyby con questo pianeta sono stati l’incipit per lo studio di due nuovi bacini, Raditladi e Rachmaninoff. Si è quindi adottato il modello cronologico MPF per derivare l’età in cui si sono formati questi due bacini. Il risultato di questa analisi è che entrambe le strutture si sono originate in un periodo successivo all’LHB, ponendo interrogativi sulle attuali sorgenti di impattori, considerando la notevole dimensione di queste due strutture d’impatto. Inoltre, le piane interne di Rachmaninoff potrebbero essere molto giovani (360 Ma fa), suggerendo un prolungato vulcanismo, e, a sua volta, una revisione delle nostre attuali conoscenze sullo stato termico di questo pianeta. Il secondo tema di questa tesi riguarda lo studio del processo di formazione di un impatto. La nostra attuale comprensione di un evento di impatto viene principalmente da studi sperimentali, morfologici, analitici e numerici. Tuttavia, gli shock code rappresentano l’unico procedimento che permette sia di esplorare condizioni non raggiungibili in laboratorio, sia di capire l’influenza di ciascuna variabile durante il processo di impatto. In questa testi, si è usato iSALE per simulare due crateri, provenienti da due ambienti molto diversi, il nostro pianeta e un asteroide recentemente osservato da una missione spaziale. Nel primo caso, la buona conoscenza della regione dove è collocato il cratere ha permesso di approfondire il meccanismo che sta alla base del collasso di un cratere di grandi dimensioni. Invece, nel secondo caso, era il processo di formazione ad essere meglio conosciuto, dal momento che si trattava di una struttura semplice, e quindi la simulazione numerica è stata finalizzata a investigare la possibile composizione e struttura superficiale di questo asteroide. In entrambi i casi, la modellizzazione numerica del processo di impatto si è dimostrato un capace tool per migliorare la nostra conoscenza del Sistema Solare.

Resumo: A pesquisa foi realizada na cratera de impacto de meteorito de Araguainha (Goiás / Mato Grosso, Brasil) e compreendeu três desenvolvimentos científicos principais. O primeiro engloba a petrografia e geoquímica de rochas graníticas parcialmente fundidas do núcleo da cratera de impacto. Foi possível separar, por petrografia e posicionamento geográfico, os litotipos do granito preservado (GP) dos litotipos de fusão (granito parcialmente fundido (GPF), veios de fusão (VF) e capa de fusão (CF)). Contudo, estes litotipos apresentam características geoquímicas muito semelhantes para elementos maiores, menores, traços e terras raras. O diagrama que se mostrou o melhor discriminante entre os litotipos de fusão e os granitos preservados foi o Th/U x TiO2, que indica enriquecimento relativo na razão Th/U nos granitos. O granito preservado é também rico em quartzo e apresenta empobrecimento em elementos como Ti, Zr, Ce, Y, Eu, Nb e elementos terras raras. Essas características permitem postular uma possível influência hidrotermal na geração dos litotipos de fusão. O segundo desenvolvimento aborda a mobilidade dos elementos traço e geração de fusões félsicas na crosta terrestre durante o impacto de meteoritos e implicações para a evolução da crosta Hadeana. Nesse caso, o processo de acresção crustal por impacto pode ser um mecanismo complementar, capaz de explicar uma importante modificação da crosta terrestre Hadeana ocorrida entre 3.9-4.5 Ga. O terceiro desenvolvimento trata dos efeitos do impacto na indução de fusão incongruente da crosta da Terra, tendo como base a fusão da biotita. O estudo mostrou que a biotita pré-impacto é distinta daquela pós-impacto, com texturas, estrutura e quimismo contrastantes. Demonstrou-se que até 9% do granito de Araguainha é produto de cristalização a partir da quebra da biotita. A biotita funde incongruentemente durante o processo de impacto, produzindo uma fusão aluminosa, que preenche bolsões e rede de fraturas nas rochas. Impactos do tamanho de Araguainha ou maiores são capazes de gerar volumes substanciais de fundidos aluminosos na crosta
Abstract: The focus of this PhD thesis is on granitic targets impacted by meteorites and felsic melting generation in the crust during impacts. Key features of the Araguainha impact crater (Goiás / Mato Grosso, Brazil) were employed as a control. Field, petrographic and analytical data collected in the study area were grouped into three, central scientific developments. The first comprises the petrography and geochemistry of partially melted granitic rocks observed in the core of the Araguainha crater. The work shows that it is possible to separate, by petrography and geographical positioning, preserved granite rocks from melt rock types, such as the partially melted granite (GPF), the melted veins (VF), and the melted caps (CF). These rock types have very similar geochemical characteristics regarding major, minor, trace and rare earth elements. However, melt rock types are readily discriminated from preserved granites in Th/U x TiO2 scatergrams; granites show relative enrichment in the ratio Th/U. Another noteworthy feature is that the preserved granite rich in quartz is depleted in Ti, Zr, Ce, Y, I, Nb and REE, indicating a possible influence of hydrothermal systems in the formation of melt products. The second development provides clues on the mobility of trace elements and generation of felsic melts in the crust during the meteorite impact, and implications for the evolution of the Hadean crust. It is argued that process of crustal accretion by impacts may have been one of the mechanisms that can explain important modification of the Earth's crust during the Hadean (3.9-4.5 Ga). The third development deals with the effects of shock-induced incongruent melting within Earth's crust, using the case of biotite melting. It was demonstrated that pre-impact and pos-impact biotites found in Araguainha show distinct textures, structures and chemistry. Results show that up to 9% of Araguainha granite is a product of magma crystallization from breakdown of biotite. The biotite melts incongruently during the impact process, producing an aluminous fusion, which fulfills pockets and fracture networks of the rocks. Impacts of the size of Araguainha or larger seem to be capable of generating substantial amounts of aluminous melt in the crust

Abstract:
Araguainha é a maior e mais bem exposta cratera complexa da América do Sul, formada em sedimentos horizontais da Bacia do Paraná. Sua portentosa estrutura com aproximados 40 km de diâmetro e 25 km de cavidade transiente revela um contraste negativo de densidade e susceptibilidade magnética na região do soerguimento central. Esta feição permite inferir um limite de propriedade física entre o Núcleo Central Soerguido (NCS) e o Embasamento Granítico Soerguido (EGS), que por sua vez apresenta baixa razão de Koenigsberger. A caracterização geofísica de Araguainha é sustentada por modelamento 2,5D com base em informações gravimétricas, aeromagnéticas e magnéticas terrestres, o que permite classificá-la como uma estrutura concêntrica e simétrica, com profundidade média do embasamento a 1,0 km, exceto para a borda sul, que apresenta soerguimento mais acentuado. A interface embasamento/sedimento é seccionada por pares espelhados de falhas radiais que surgem no estágio de modificação da cratera. Estas estruturas rúpteis conferem as maiores profundidades à região da bacia anelar e promovem constricção dos sedimentos com tensão horizontal radial. A observação e interpretação destas deformações permitem caracterizar Araguainha como uma estrutura de impacto de domínio rúptil-dúctil.
Araguainha is the largest and the best-exposed complex crater of South America, formed in horizontal sediments of the Paraná Basin. Its portentous structure with 40 km in diameter and 25 km of transient cavity reveals a negative contrast of density and magnetic susceptibility in the central uplift. That feature allows to infer a limit of physical property between the uplifted central core and the uplifted granite basement, which shows a low Konigsberger?s ratio. The geophysical characterization of Araguainha is sustained by 2,5D modeling with gravity, aeromagnetic, and ground magnetic information and It allows to classify it as a concentric, symmetrical structure, with average basement depth of 1.0 km, except in the southern rim, that shows a bigger uplift. The basement/sediment interface is cut by specular pairs of radial faults that appears in the modification stage of the crater. These brittle structures are responsible for the biggest depths in the annular basin region, and they promote a sediment constriction with horizontal radial tension. The observation and interpretation of these deformations allow to characterize Araguainha as an impact brittle-ductile domain structure.

Abstract:
AbstractThe training of automated container gantry crane drivers faces with challenges, such as high safety risks, difficult training, and high learning cost. Therefore, we have designed an intelligent simulation system architecture for automated container quay cranes training based on embedded digital twin technology. This system can be directly embedded into the real quay crane remote control console without changing the original quay crane hardware equipment. It enables real-time switching between virtual quay crane remote control operation simulations and real gantry crane remote control operation, providing training for quay bridge drivers while also accounting for the real quay crane operation in time. To achieve seamless switching between real control and simulation training, we have designed two types of controllers: an automatic quay bridge remote control operation simulation system based on OPC UA communication protocol, and a real quay crane automation controller based on PLC control bus. Both controllers can communicate bidirectionally with the remote control room operating station PLC. Practical application at a wharf has demonstrated that our designed system offers high safety, real operation experience, and significant training effectiveness, effectively improving automated quay crane training outcomes, efficiency, and effectiveness.

Abstract:
AbstractThe wind-induced response and wind vibration coefficient of tower cranes under different wind speed spectra and wind direction angles are investigated to reveal the influence of wind speed distribution on the wind vibration characteristics of tower cranes. Firstly, the theoretical formula for the wind vibration coefficient based on random vibration theory is derived. Then, the APDL modeling method establishes a parametric finite element analysis model with the QTZ25 tower crane as a research object, and wind speed time history at various heights is simulated using the harmonic synthesis method. Finally, the wind speed is converted into wind loads, and the finite element model of the QTZ25 crane is subjected to random vibration analysis and spectra analysis under wind loads. The displacement time history response and displacement power spectral density at different heights are obtained, and the wind vibration coefficients are derived accordingly. The analysis results show that the wind vibration coefficient in descending order is Simiu, Davenport, and Harris wind speed spectra excitation (WSSE), respectively. The maximum deviation of the wind vibration coefficient is 12.01% at 26.09 m height with a 45° wind direction angle. In contrast, the maximum deviation of the wind vibration coefficient is 18.57% at the same height with a 0° wind direction angle. This study demonstrates that the wind-induced response of the QTZ25 tower crane remained the same under different wind speed spectra. Meanwhile, the wind vibration coefficient varied for different heights and wind direction angles, and the wind vibration coefficient was higher under Simiu WSSE and lower under Harris WSSE.

Abstract:
Crawler cranes are the most expensive and frequently shared resource on construction sites, industries, etc. It is engaged in offering various combination for booms and large-capacity of mobile cranes to meet the building industry requirements. Computer simulation has proved to be an effective tool for aiding practitioners in modeling complex construction operations, especially three-dimensional simulation that can provide interactive, three-dimensional graphics. As a graphic standard, OpenGL has powerful three-dimensional graphic processing abilities, but is weakness in three-dimensional modeling. Bounding Hierarchical Volumes Tree (BHVT) is very popular structures for objects storage of virtual scenes. Based on BHVT, a method of three-dimensional modeling is proposed. According to its structure and characteristics, the model of the crawler crane is designed. To achieve three-dimensional simulation for a main hoisting crane and an assistant crane (i.e., sliding tail crane) cooperative lifting, several typical mathematical models are established. When simulating the lifting process in the cooperative working mode, the changes of cranes and the lifting equipment, needed for steady lifting, are figured out simultaneously, and then those changes are output to form the relevant curves. The curves are analyzed to decide whether the lifting plan that using a main hoisting crane and a sliding tail crane to lift is safe and reasonable. For the sake of a better interactive simulation, object-oriented framework for three-dimensional graphic creation based on OpenGL is developed, it consists of class BHVTNode, class camera and class renderer, which make data and instructions separated. Combining the class camera and class renderer with the technology BHVT, succeed to simulate the lifting operations of crawler crane, especially achieve the animation of the cooperative lifting, it is visual to observe the whole lifting process, which is good for assisting to design the lifting plan.

Abstract:
Film cooling is studied for cylindrical holes embedded in craters. Different crater geometries are considered for a typical crater depth. Cratered holes occur when blades are coated with thermal barrier coating layers by masking the hole area during TBC spraying. The film performance and behavior will be different for the cratered holes compared to standard cylindrical holes. FLUENT is used to simulate film cooling for the different crater geoemtries and compared to baseline uncratered cylindrical holes. Film effectiveness is reduced by the cratering compared to earlier studies which had two-dimensional trenches instead of craters. The study is performed at a single mainstream Reynolds number based on free-stream velocity and film hole diameter of 11000 at one different coolant-to-mainstream blowing ratio of 1.0.

Abstract:
Abstract Molybdenum splats were produced at three plasma conditions on steel substrates preheated to three temperatures. Morphology of splats and corresponding craters formed on substrates were observed; dimensions of splats and craters were measured with an optical non-contact interferometer. It is found that substrate is significantly melted and deformed upon impact of the droplet, which leads to the formation of flower like splats and craters. On average, only about 36 to 53 % of the areas covered by splats were in good metallurgical/mechanical contact with substrate. Normalized crater volume increases with droplet size and the contact is improved for the high particle energy/high substrate temperature condition as compared with low particle energy/medium substrate energy condition. Splat morphology and crater formation is explained based on impinging jet heat transfer model.

Abstract:
ESA desires to land on the Moon within the European Large Logistics Lander (EL3) program. EL3 comprises multiple landers, each aiming for a different landing site. To this end, the landers require a GNC system that can precisely reach any desired landing site on the entire Moon. Landing with high accuracy requires to include an absolute navigation method into the GNC system, which makes the landers MCMF pose observable. With the crater navigation system, CNav, one such method has been developed at DLR. The basic concept is first detecting impact craters in images periodically acquired of the lunar surface. The second step is matching the craters detected within that image with the ones included in an a priori determined database. From these matches the spacecraft’s absolute position and orientation is determined. Our system uses three different matching strategies which are autonomously selected by considering the system’s current state and other parameters. This advanced matching scheme allows for global navigation, offering a moderate measurement frequency at coarse navigation knowledge, and high-speed operation at tracking-grade state accuracy. A typical CNav operation begins with the crater detector robustly extracting craters from images of the underlying lunar surface taken by the spacecraft. Then, the crater candidates are to be matched against a crater catalog using the advanced matching scheme. The first matching technique is a form of lost-in-space matching, which in principal can be performed in the absence of any a-priori state knowledge. We call this acquisition mode. In case of better on-board navigation accuracy, e.g. from a prior successful CNav solution or from ground updates, a faster, more robust matching mode approach can be used: the tracking mode. After its successful operation, any matching method includes a thorough match verification strategy, which ensures that the probability of a false match is low. During extensive testing it was found that less than 1 percent false matches remain undetected and are returned by the method. Even then the remaining false matches can most likely be detected in a later stage by means of navigation filter internal measurement checking. DLR has a global crater database of more than 40 Mio craters available which serves as a basis for generating the on-board crater catalogs. Thus, CNav can be employed for landing everywhere on the Moon, provided sufficiently illuminated images can be taken and craters are present. Especially at the lunar south pole, it can be difficult to satisfy these two constraints. However, the south pole is one of the prime targets of future missions such as EL3. Therefore, an analysis has been performed in the context of DLR’s contribution to the EL3 study to demonstrate the applicability and performance of CNav for a landing at the south pole. It has been demonstrated that viable approach trajectories exist which are sufficiently illuminated and contain sufficient craters to deliver CNav results down to altitudes of around 1 km above the landing site. In addition, a more detailed investigation of the landing conditions and their impact of the applicability of optical methods for landing on the south pole has been performed. We conclude that landing at or close to the south pole is feasible using CNav. In the paper we will present the results of both the illumination analysis and the CNav performance for a landing at the lunar south pole, thereby we will demonstrate that DLR’s crater navigation can be used to land an EL3 lander at the south pole.

Abstract:
Abstract This paper presents a novel approach for implementation of digital twin (DT) based Structural Health Monitoring (SHM) of an Palfinger offshore knuckle boom crane. Contrary to most harbor gantry cranes, knuckle boom cranes are highly nonlinear mechanisms that cannot be represented by static reduced order twin models. Such cranes need to be solved by non-linear finite element solvers. The digital twin representation of the Palfinger crane is modelled and simulated real-time in a nonlinear finite element (FE) program, driven by inputs from physical sensors. Model reduction techniques are applied to enable DT co-simulation running two times faster than the physical crane. The inputs from the standard crane instrumentation are processed for noise reduction and singularity removal and converted to hydraulic actuator inputs. A simple inverse method for estimation of the crane payload is implemented based on hydraulic pressures. Structural loads due to wave induced ship motions are predicted based on sensor signals from the ship IMU. Based on the standard ship and crane instrumentation, the digital twin allows for real-time determination of stresses, strains and loads at an unlimited number of hot spots. Hence, a digital twin can be an effective tool for predictive maintenance of real offshore knuckle boom cranes with minor additional costs. The presented approach is described in a general manner and is applicable for offshore cranes used in the industry.

Cranes are used extensively throughout the world in a wide variety of construction and material handling applications. The speed at which these cranes are operated is limited by payload oscillation. Input shaping is one method that reduces this oscillation, allowing higher speeds and improving operational efficiency. Another method to improve the operational capabilities of cranes is to allow base motion. This paper presents initial experimental results from a portable, mobile tower crane. A theoretical model of the crane is presented and experimentally verified. The oscillatory dynamics of the crane are highlighted and controllers to combat these unwanted dynamics are presented.

Abstract:
As sandhill crane populations continue to grow in the United States, so too does crop damage, property damage to homeowners, and the risk of crane collisions with aircraft. Whooping crane populations also continue to grow, but with a global population of about 500 individuals (as of 2017), damage is rare and problems often require different solutions due to the species’ endangered status. The sandhill crane (Grus canadensis), is a long-lived, member of the crane family (Gruidae) and the most numerous of the 15 crane species found worldwide. Over the last 50 years, the species has grown from a rarity─ requiring extensive protection─ to an abundant, widespread species. As their populations have increased, so too have their conflicts with people. Both sandhill and whooping cranes are protected under the Migratory Bird Treaty Act (MBTA) of 1918. This law strictly prohibits the capture, killing, or possession of sandhill and whooping cranes without proper permits. However, the U.S. Fish and Wildlife Service (USFWS) can issue depredation permits under this act for the shooting of sandhill cranes that causeagricultural damage or threaten human health and safety. No federal permit is required to use non-lethal management methods to reduce damage by sandhill cranes.

Abstract:
Research was conducted at the U.S. Army Engineer Research and Development Center (ERDC) in Vicksburg, MS, to identify alternative repair methods and materials for large crater repairs using Rapid Set Concrete Mix®. This report presents the technical evaluation of the field performance of full-depth slab replacement methods conducted using Rapid Set Concrete Mix® over varying strength foundations. The performance of each large crater repair was determined by using a load cart representing one-half of the full gear of a C-17 aircraft. Results indicate that using rapid-setting concrete is a viable material for large crater repairs, and the performance is dependent on surface thickness and base strength.

Abstract:
The Rapid Airfield Damage Recovery (RADR) Next Generation Backfill Technology Comparison Experiment was conducted in July 2017 at the East Campus of the U.S. Army Engineer Research and Development Center (ERDC), located in Vicksburg, MS. The experiment evaluated three different crater backfill technologies to compare their performance and develop a technology trade-off a nalysis. The RADR next generation backfill technologies were compared to the current RADR standard backfill method of flowable fill. Results from this experiment provided useful information on technology rankings and trade-offs. This effort resulted in successful crater backfill solutions that were recommended for further end user evaluation.
