Abstract:
AbstractLet $$g(z)=\int _0^zp(t)\exp (q(t))\,dt+c$$ g ( z ) = ∫ 0 z p ( t ) exp ( q ( t ) ) d t + c where p, q are polynomials and $$c\in {\mathbb {C}}$$ c ∈ C , and let f be the function from Newton’s method for g. We show that under suitable assumptions on the zeros of $$g''$$ g ′ ′ the Julia set of f has Lebesgue measure zero. Together with a theorem by Bergweiler, our result implies that $$f^n(z)$$ f n ( z ) converges to zeros of g almost everywhere in $${\mathbb {C}}$$ C if this is the case for each zero of $$g''$$ g ′ ′ that is not a zero of g or $$g'$$ g ′ . In order to prove our result, we establish general conditions ensuring that Julia sets have Lebesgue measure zero.

Abstract:
What it is like to sleep in zero gravity? Is it ever occurred to you? Sleep is actually a physical and mental resting state in which a person becomes relatively inactive, unaware of the environment, and is partially detachment from the world. It is a challenge for architects to design in a very extreme environment, which has different gravity, radiation exposure to avoid, the absence of basic needs (water, oxygen, etc.), sense of orientation (where is the top and where is the bottom?) etc. The lack of ability for human to stand straight in zero gravity environment – fetal position – leads to the choosing of that position for designing sleeping compartment in space – mimicking a sleeping baby, which is, in fact, the healthiest sleeping position. This idea becomes our guideline in proposing the design of a sleeping compartment in zero gravity, particularly in space station. It gives potential advantage for reducing the payloads of habitat module; size and weight, which is a common problems in space travel; mainly for reducing fuel and cost. But on the other hand, the quality of a good sleep should be considered, which is the main aspect of this design. What is a feasible sleeping compartment design for optimizing those needs? This research uses a design exploration approach to solve the problems and to find a suitable solution. The end result from this activity is S.H.E.E.P; Safe Haven with Ergonomics and Effective Performance. This sleeping compartment design is a private space for crew to rest comfortably without any interference from the external environment. This compartment is also equipped with necessary tools.

Abstract:
Let $A \in {\cal C}^n$ be an exceptional extremal copositive $n \times n$ matrix with positive diagonal. A zero $u$ of $A$ is a non-zero nonnegative vector such that $u^TAu = 0$. The support of a zero $u$ is the index set of the positive elements of $u$. A zero $u$ is minimal if there is no other zero $v$ such that $\Supp v \subset \Supp u$ strictly. Let $G$ be the graph on $n$ vertices which has an edge $(i,j)$ if and only if $A$ has a zero with support $\{1,\dots,n\} \setminus \{i,j\}$. In this paper, it is shown that $G$ cannot contain a cycle of length strictly smaller than $n$. As a consequence, if all minimal zeros of $A$ have support of cardinality $n - 2$, then $G$ must be the cycle graph $C_n$.

Abstract:
AbstractLet G be a finite group acting on vector spaces V and W and consider a smooth G-equivariant mapping f: V → W. This paper addresses the question of the zero set of f near a zero x with isotropy subgroup G. It is known from results of Bierstone and Field on G-transversality theory that the zero set in a neighbourhood of x is a stratified set. The purpose of this paper is to partially determine the structure of the stratified set near x using only information from the representations V and W. We define an index s(Σ) for isotropy subgroups Σ of G which is the difference of the dimension of the fixed point subspace of Σ in V and W. Our main result states that if V contains a subspace G-isomorphic to W, then for every maximal isotropy subgroup Σ satisfying s(Σ) > s(G), the zero set of f near x contains a smooth manifold of zeros with isotropy subgroup Σ of dimension s(Σ). We also present partial results in the case of group representations V and W which do not satisfy the conditions of our main theorem. The paper contains many examples and raises several questions concerning the computation of zero sets of equivariant maps. These results have application to the bifurcation theory of G-reversible equivariant vector fields.

Abstract:
The ‘Zero-G’ is designated as a new class of underwater robot that is capable of unrestricted attitude control. A novel control scheme based on internal actuation using Control Moment Gyros (CMGs) is proposed to provide Zero-G Class Autonomous Underwater Vehicles (AUVs) with this unique freedom in control. The equations of motion for a CMG actuated underwater robot are derived and a nonlinear feedback control law formulated based on energy considerations of the system’s coupled dynamics. Singularities, redundancy and null motion are discussed in the context of CMGs and a mathematical escapability condition is developed based on the differential geometry of null motion. A comprehensive geometric study of the singularities of a CMG pyramid is performed and together with considerations of the inverse kinematics of attitude control form the basis of a global steering law that exactly achieves the desired torques, whilst guaranteeing real-time singularity avoidance within a constrained workspace. The development of the CMG actuated Zero-G Class underwater robot IKURA is described. This is the first Zero-G Class prototype and is the first application of CMGs to underwater robots. A series of experiments to demonstrate the practical application of CMGs and verify the associated theoretical developments is described. The open-loop dynamics of the system and the exactness and real-time applicability of the CMG steering law are verified. Experiments are carried out to assess the performance of the proposed control law by comparing the response of the robot to that using alternative control laws that neglect the hydrodynamic interactions of the body and the coupled motion of the CMGs and body respectively. The control law demonstrates a faster response with a smaller overshoot for less overall control activity than the alternative methods. The ability to actively stabilise the passively unstable translational dynamics of the robot are verified. Next, the unrestricted attitude control capability is confirmed with the robot demonstrating the necessary range of attitude control to adopt and maintain any attitude on the surface of a sphere. Finally, the ability to stabilise any attitude while translating in surge is confirmed with the robot performing vertically pitched diving and surfacing in surge. This is the first time an underwater robot has performed such a manoeuvre. This research demonstrates that CMGs are capable of actively stabilising the passively unstable dynamics of an underwater robot with essentially zero-righting moment and are capable of providing it with unrestricted attitude control. The three-dimensional manoeuvring capabilities allow Zero-G Class underwater robots to plan and optimise their missions in a fully threedimensional manner, in a way that has not been possible previously. This study concludes that the application of CMGs for attitude control opens up a path to develop sophisticated Zero-G Class underwater robots and their application to new fields of underwater research.

"Development of a multi-criteria, GIS-based, backcasting framework model (G-BFM) for progression towards zero waste futures, for holistic resource management policy and practice in Northamptonshire by 2050." Thesis, University of Northampton, 2015. http://nectar.northampton.ac.uk/9131/.

Abstract:
The complex nature of waste management and planning requires a long-term strategic policy formation approach incorporating sustainable development principles. Consequently, the transition from a waste paradigm to valuing materials as resources is central for transitioning towards a 'zero waste' future. A need is identified, via infrastructure planning, to move beyond short-term forecasting and predictive methods previously used in waste research in order to overcome target-driven decision-making. The application of a participatory backcasting methodology: visioning, baseline assessment, scenario development and feasibility testing; produced transformative scenarios which are visualised using GIS reflecting the choices, ideas and beliefs of participants. The structural governance (e.g. waste infrastructure planning and strategic waste policy) of an English county is used to evaluate the efficacy of waste management scenarios. A quantitative model was developed to test scenarios for three metrics (tonnages, economics and carbon). The final model utilises the synergy between backcasting and GIS to spatially and temporally analyse empirically quantified outputs. This structured approach produced three transformative scenarios and one reference scenario. Waste prevention and changes to systemic waste generation produced long-term tonnage reductions across the transformative scenarios. Costs of future waste management witnessed the reference scenario outperforming one of the transformative scenarios; while the highest emissions savings were attributable to the scenario most closely reflecting the notion of 'deep sustainability'. In terms of waste infrastructure planning, a centralised pattern of large integrated facilities emphasising catchments rather than administrative boundary were most effective. All three transformative scenarios surpassed the 90% recycling and recovery level used as the zero waste benchmark. The research concludes that backcasting can offer a range of potential futures capable of achieving an arbitrary definition of zero waste. Further, these futures can be visualised and analysed via GIS; enhancing stakeholder engagement. Overall, the GIS-based Backcasting Framework Model (G-BFM) produced has the potential to benefit a range of stakeholders and practitioners and is strategically scalable.

Ces simulations sont basees sur le modele statistique de g. Fai et j. Randrup mis en uvre sous forme d'un code informatique freesco generant les particules emises lors de lma collision. Des resultats tires de ce code montrent que la multiplicite de particules et fragments emis de la collision au+au a 1 gev/u est tres elevee (300) et que la moitie de ces particules et fragments sont des neutres. Les simulations de la partie mur interne tiennent compte, pour les particules et fragments emis entre 0 et 7,5 degres, de la perte d'energie, des fluctuations de perte d'energie et de la diffusion coulombienne multiple dans les differents materiaux entre la cible et le mur interne. Les resultats de ces simulations montrent la bonne identification des differentes charges detectees sur le mur interne ainsi que la bonne efficacite de ce detecteur. La resolution sur la reconstruction du plan de reaction est en accord qualitatif avec les resultats experimentaux de la boule de plastique (berkeley) mais les calculs ne permettent pas d'extraire une valeur du flot de matiere nucleaire a partir des donnees du seul mur interne. Cependant, une valeur de cette observable, importante dans l'evaluation de l'equation d'etat de la matiere nucleaire, peut etre extraite d'une maniere satisfaisante a partir des donnees du domaine 0-30 correspondant a tout le mur de plastique (mur interne et mur externe) du detecteur 4 du g.

The main theme of this dissertation is about women murders in Rio Grande do Sul and aims to analyze the social representations of the phenomenon produced by the media. For that, was searched for news stories involving cases of lethal violence against women, in a digital database of the Zero Hora newspaper, published in the period from January to December 2016. From this research, 48 reports was found, all in the police section, and 6 headlines. Was sought to understand the media's perspective in cases of homicide of women, the emphasis given in some cases to that reports, the relevance of mentioning the victim?s criminal record and / or their involvement in drug trafficking, and situations in which homicide is identified as a crime of passion.It is understood that the lethal violence of women occurs in several situations, which give rise to quite singular configurations. In these homicide arrangements, the gender element - constitutive of social relations - may or may not be present as drive of violence. However, the media darken the gender aspect, making it difficult to understand homicides from their complexity. For the theoretical support of the research, was opted for the theory of social representations, of Serge Moscovici and for the studies developed in gender and sexuality scope. Regarding the theoretical-methodological procedures, the qualitative approach and the set of content analysis techniques were adopted in their thematic modality for data systematization and interpretation. The results pointed out that the media deals with the murder of women covering the possible motivations based on unequal gender relations. The news framing is exclusively in police way, that means, doesn?t consider the multiple dimensions that involves violence against women. The media also produce representations of intimate partner violence in which it is reduced to a crime of passion. These results enable further study in the area, paving the way for future research, and challenge the media to incorporate gender equity into the way they interpret female homicides. The violence between intimate partners is reduced to a crime of passion in representations produced by the media. These results enable further studies in the area, paving the way for future researches, and challenging the media to incorporate gender equity into the way that they interpret female homicides.
O tema geral desta disserta??o ? o homic?dio de mulheres no Rio Grande do Sul e tem como objetivo analisar as representa??es sociais do fen?meno produzidas pela m?dia. Para isso, buscou-se mat?rias de cunho noticioso envolvendo casos de viol?ncia letal contra mulheres em banco de dados digital do Jornal Zero Hora, veiculadas no per?odo de janeiro a dezembro de 2016. A pesquisa resultou em 48 reportagens, todas no caderno policial, e 6 chamadas de capa. Procurou-se compreender a leitura realizada pela m?dia sobre os casos de homic?dio de mulheres, o destaque dado a alguns casos pelo notici?rio, a relev?ncia em mencionar os antecedentes criminais da v?tima e/ou seu envolvimento com o tr?fico de drogas e as situa??es em que o homic?dio ? identificado como crime passional. Compreende-se que a viol?ncia letal de mulheres ocorre em diversas situa??es, as quais originam configura??es bastante singulares. Nestes arranjos de homic?dio, o elemento de g?nero ? constitutivo das rela??es sociais ? pode ou n?o estar presente como motivador da viol?ncia. Todavia, a m?dia oculta o aspecto de g?nero, dificultando a compreens?o dos homic?dios a partir de sua complexidade. Para dar sustenta??o te?rica ? pesquisa, optou-se pela teoria das representa??es sociais, de Serge Moscovici e pelos estudos desenvolvidos na ?rea de g?nero e sexualidade. Quanto aos procedimentos te?rico-metodol?gicos, foi adotada a abordagem qualitativa e o conjunto de t?cnicas da an?lise de conte?do na sua modalidade tem?tica para sistematiza??o e interpreta??o dos dados. Os resultados apontaram que a m?dia trata do homic?dio de mulheres ocultando as poss?veis motiva??es baseadas nas rela??es desiguais de g?nero. O enquadramento da not?cia ? exclusivamente policial, ou seja, n?o considera as m?ltiplas dimens?es que envolve a viol?ncia contra a mulher. A m?dia tamb?m produz representa??es da viol?ncia entre parceiros ?ntimos em que ela ? reduzida a um crime passional. Estes resultados possibilitam o aprofundamento de estudos na ?rea, abrindo caminho para pesquisas futuras, e desafia a m?dia para que incorpore a equidade de g?nero na forma como interpretam os homic?dios de mulheres.

Abstract:
Chapter 9 by M. G. Tertr and B. Saveyn provides an estimate of the investment needs and additional costs of bringing the EU’s dependence on fossil fuels from Russia to zero by 2027, with a specific focus on natural gas. This analysis was used to prepare the REPowerEU plan presented by the Commission on the 18th of May 2022. Decoupling the EU from Russian fossil fuel imports has already begun and will pass through various stages affecting both demand and supply. From this perspective, the analysis indicates that implementing the full potential to reach zero-dependence could require 300 billion euros cumulative from now to 2030—which is beyond the Fit for 55 proposal. By the end of 2027, this transition could correspond to approximately 210 billion euros in investment. These REPowerEU investments correspond to about 5% of the total Fit for 55 investments up to 2030 and would come in addition to them. The Commission analysis estimates that the Fit for 55 and REPowerEU measures combined could save the EU 80 billion euros annually on gas imports, 12 billion euros on oil imports, and 1.7 billion euros on coal imports.

Abstract:
This chapter presents proofs of following theorems. Theorem 6.1: Suppose N in Garith is geometrically semisimple. Then Ggeom,N is a normal subgroup of Garith,N. Theorem 6.2: Suppose that N in Garith is arithmetically semisimple and pure of weight zero. If Garith,N is finite, then N is punctual. Indeed, if every Frobenius conjugacy class FrobE,X in Garith,N is quasiunipotent, then N is punctual. Theorem 6.4: Suppose that N in Garith is arithmetically semisimple and pure of weight zero. If Ggeom is finite, then N is punctual. Theorem 6.5: Suppose that N in Garith is arithmetically semisimple and pure of weight zero. Then the group Ggeom,N/G⁰geom,N of connected components of Ggeom,N is cyclic of some prime to p order n.

Abstract:
There is an urgent need for large-scale restoration across the Amazon, which has suffered decades of deteriorating ecological conditions and is fragile in the face of climate change. Restoration at scale can be achieved through seven complementary targets: (a) Achieve zero deforestation by 2030; (b) Avoiding forest degradation; (c) Restoring forests in protected areas; (d) Restoring forests in undesignated lands; (e) Restoring areas that have been cleared above the legal allowance on private lands; (f) Restoring forest cover beyond legal compliance; and (g) Sustainable restoration of degraded farmland.

Abstract:
Extending the previous two years of research results (Mizarch, et al, 2012, Tao, 2011, 2012), the third year’s efforts in both Maryland and Israel were directed towards the engineering of the system. The activities included the robust chick handling and its conveyor system development, optical system improvement, online dynamic motion imaging of chicks, multi-image sequence optimal feather extraction and detection, and pattern recognition. Mechanical System Engineering The third model of the mechanical chick handling system with high-speed imaging system was built as shown in Fig. 1. This system has the improved chick holding cups and motion mechanisms that enable chicks to open wings through the view section. The mechanical system has achieved the speed of 4 chicks per second which exceeds the design specs of 3 chicks per second. In the center of the conveyor, a high-speed camera with UV sensitive optical system, shown in Fig.2, was installed that captures chick images at multiple frames (45 images and system selectable) when the chick passing through the view area. Through intensive discussions and efforts, the PIs of Maryland and ARO have created the protocol of joint hardware and software that uses sequential images of chick in its fall motion to capture opening wings and extract the optimal opening positions. This approached enables the reliable feather feature extraction in dynamic motion and pattern recognition. Improving of Chick Wing Deployment The mechanical system for chick conveying and especially the section that cause chicks to deploy their wings wide open under the fast video camera and the UV light was investigated along the third study year. As a natural behavior, chicks tend to deploy their wings as a mean of balancing their body when a sudden change in the vertical movement was applied. In the latest two years, this was achieved by causing the chicks to move in a free fall, in the earth gravity (g) along short vertical distance. The chicks have always tended to deploy their wing but not always in wide horizontal open situation. Such position is requested in order to get successful image under the video camera. Besides, the cells with checks bumped suddenly at the end of the free falling path. That caused the chicks legs to collapse inside the cells and the image of wing become bluer. For improving the movement and preventing the chick legs from collapsing, a slowing down mechanism was design and tested. This was done by installing of plastic block, that was printed in a predesign variable slope (Fig. 3) at the end of the path of falling cells (Fig.4). The cells are moving down in variable velocity according the block slope and achieve zero velocity at the end of the path. The slop was design in a way that the deacceleration become 0.8g instead the free fall gravity (g) without presence of the block. The tests showed better deployment and wider chick's wing opening as well as better balance along the movement. Design of additional sizes of block slops is under investigation. Slops that create accelerations of 0.7g, 0.9g, and variable accelerations are designed for improving movement path and images.
