EVOLUTIONARY ALGORITHMS APPLIED TO LOW-THRUST FORMATION FLYING TRAJECTORY OPTIMIZATION

This paper investigates the application of evolutionary algorithms (EAs) for the fuel-optimal low-thrust formation flying trajectory optimization (FFTO) under the two control direction constraints based on the Clohessy-Wiltshire equations. First, by applying the Pontryagin’s maximum principle, the first-order necessary optimality conditions are derived, which allow for using the initial costates to parameterize the FFTO problem. The search space of the initial costates is determined by enlarging the initial costates of the associated optimal impulsive trajectory. A penalty method is adopted by the EAs to find the optimal solution that satisfies the equality constraints presented in the shooting function. To settle the control discontinuity when propagating the trajectories, an integrator equipped with events detection technique is adopted to automatically determine the switching times according to the switching function. Finally, numerical examples are given to illustrate the performance of the method.
Neural Structured Turing Machine

Differential external memory has greatly improved attention based model, such as neural Turing machines(NTM), however none of existing attention models and memory augmented attention models has considered real-valued structured attention, which may hinders their representation power. Here we take structured information into consideration and propose a Neural Structured Turing Machine(NSTM). Our preliminary experiment on varied length sequence copy task shows the benefit of such structured attention mechanism, leading to a novel perspective for improving differential external memory based mechanism, e.g., NTM.

Criptografia como Ferramenta para o Ensino de Matemática

No centro dos problemas do ensinoaprendizagem em matemática reside a motivação. O aluno não tem atenção para conteúdos que necessitem de abstração ou generalização, sutilezas são totalmente desconhecidas. Por outro lado, o mesmo aluno tem muita atenção para qualquer aparato de alta tecnologia ou assuntos que instiguem seus sentidos. A maioria das aplicações que são usadas nos cursos de graduação envolve pouco sentimento. Além do mais, as aplicações mais belas requerem muito conteúdo, estão no final de uma disciplina e normalmente não são ensinadas. Para motivar o aluno, não basta dizer que todo aparato tecnológico foi constrúıdo a partir de fundamentos matemáticos, ele não vai se motivar a estudar álgebra booleana porque é a base da computação, muito menos cálculo para saber como uma máquina calcula o seno. Ele busca algo novo e não percebe que é necessário conhecer o que existe para poder construir algo novo. Muitos alunos também se apegam a um conhecimento adquirido a partir de ações, algo que possa ser visualizado. Para eles não basta dizer que a série de Fourier é a base da transmissão de sinais [23], ou dizer que os celulares usam a série de Fourier para comunicação, eles querem ver como isto é feito. Infelizmente é inviável mostrar isto a um aluno no ińıcio de sua graduação, no entanto, veremos que isto é fácil quando a motivação surge da aplicação em criptografia. O objetivo básico da criptografia é transmitir uma mensagem a um destinatário sem que outra pessoa possa compreender seu conteúdo. Com o intuito de atingir este objetivo, usa-se todo o conhecimento dispońıvel. Diferente de outras aplicações que requerem um grande conteúdo, pode-se iniciar os estudos com criptografia com conceitos elementares como a contagem. Porém o embasamento matemático não fica em conteúdos básicos, partindo desta aplicação, o professor pode atingir os maiores problemas da atualidade, que são estudados nos departamentos de matemática pura. Foi muito surpreendente a chamada de trabalhos do VIII Simpósio Brasileiro em Segurança da Informação e de Sistemas Computacionais (SBSeg 2008):
CombiningKnowledge Based System withInformation Technology based ProjectManagement

Using the growingtrend for better project management is very much essential and widespread, particularly for information technology (IT) based projects. Many institution’s today have a new or renewed techniques and methods in handling project management. The Internet, computers devices, softwaresystems, applications, knowledge and the practice of interdisciplinary is aworldwide effort and it hascompletely changed the project management activities.Most of IT project need to use some computer applications for more efficient and great quality to increase reliability and improve productivity and also to avoid any failure that may occur. Hence Knowledge based system is (KBS) is a kind of computer database that motivates projects and uses knowledge to solve complex problems. Combining this kind of systems with IT project management will help the integration of these systems to support IT projects management in order to improve the quality, better management and reliability of these projects.The main purpose of this paper isto explore the possibilities of ongoing effect of combining knowledge management system with IT projects management. This will provide the sufficientreview of the idea of knowledge based project management. It discusses the various reasons for managing IT projectcombining with knowledge bases systems. Additionally the paper surveys a number of studies to classify the practices of KBS and IT projects. Finally, the paper highlights in the conclusion as knowledge based systems will be a good tool for IT project management.
Mobile Hotspot in Railway System

With the ever-growing need for mobile high-speed access, there is an apparent demand to extend access towards mass transportation vehicles such as trains. In this paper, we propose a novel networking paradigm for railway system. The architecture realizes spatial diversity, and transparency to mobile devices. We further investigate the link layer design approach of the architecture, with the use of erasure coding. The concept of information raining is explained, with simulations illustrating system throughput cyclicity due to positioning of vehicle.
JP1.9 A QUANTITATIVE COMPARISON OF MM5 CLOUD FORECASTS AND GOES CLOUD ANALYSES

In order to mitigate the influence of adverse weather, it has become routine for government and civil organizations to rely on Numerical Weather Prediction (NWP) models to make operational decisions (Roebber and Bosart, 1996). But NWP cloud simulations are fraught with challenges that limit their accuracy. No routine observations of cloud water and cloud ice are taken, therefore NWP models are usually initialized with zero cloud condensate or with condensate mass distributions obtained from earlier runs. Microphysics cloud parameterizations are usually validated based on case studies of winter storm events (e.g. Schultz, 1995). But how well do models forecast clouds on a day-to-day basis, particularly when forcing is weak or terrain-dependent? Our study answers this by statistically comparing cloud forecasts from a high-resolution mesoscale model with cloud analyses from a meteorological satellite.

ASSESSMENT OF IMPACTSON GEOSYSTEMS IN OIL PRODUCTION REGION

This article presentsa sample assessment of contribution of several impact sources to the groundwater condition in the intensive oil production region (PJSC Tatneft) (Tatarstan, Russia). The method proposed is designed to minimize the subjectivity of the assessment and permits to derive the map of a man made impact on the groundwater. The use of river basins is argued as a main spatial unit for characterization of the anthropogenic impact and the environment state due to its scalability properties. Proposed combination of GIS technologies, spatial analysis and statistical approach makes it possible not only to quantify the human impact on the environment, but also to determine the contribution of individual industries as well as to evaluate the quality of the assessment.
Word frequency effects and inter-item associations . A study of the N 400 Kristoffer Åberg

High frequency words are easier to recall compared to low frequency words in lists of only one frequency-range. This effect disappears when words of different frequencies are mixed in a list. Word frequency effects have often been assumed to rely on associations between words. The relationship between word frequency and associations was investigated by controlling associations using Latent Semantic Analysis (LSA) in an experiment of free recall. Event-related potentials (ERPs) were recorded and analysis focused on the N400 component. Behavioral results support the assumption that high frequency words have more associations than low frequency words while electrophysiological data do not. There was still a frequency effect in the N400 for lists of associated words. Results are not conclusive since the attempt to replicate word frequency effects in literature was unsuccessful and replication of results is necessary.
Problem-based Teaching in Construction Law

The construction industry is an exciting place to work, often you are involved in interesting projects and creative problem solving is part of the daily work. In the construction engineering educations we prepare the coming engineers very well on all the positive work tasks and competencies they must hold. But, in the last decade there has been an increasing tendency towards using contracts, agreements and laws much harder and directly in construction projects. Some argues that the success of a project now depends on if one can remember the “general conditions” of Danish construction (called AB92, ABR89 and ABT92) in sleep. To prepare the students for this situation is much harder and sadly often neglected in the education. On the other hand, there is much attention on cooperation in construction, e.g. Partnering. The idea is then to decrease the focus on contracts and increase the cooperation to reach a smoother problem solving process. It is, however not either contracts or Partnering. The students must learn both, and in ever Partnering project the contractual agreements should still be well founded. This paper describes how we at Aalborg University in Denmark teach construction law – in fact engineering students may take several different courses in that area. The teaching form is centred on Problem Based Learning and student engagements. Cases from the “real world” are, therefore, used and the students get to work in groups to discover problems and solutions them self. The teaching is hence not to compare with traditional lecturing, but instead it is more similar to workshops. Experiences so fare has shown that the students are keen on this way of learning, and more over engineers with a couple of years practices and who has participated in these classes seems to be very well prepared for the continuous battling of laws, contracts and agreements.
A Novel Flying Capacitor Multilevel Inverter With Stable Output Voltage

Multilevel inverters (MLI) are plays an important role in industrial power applications. Generally conventional MLIs are categorized into diode clamped, flying capacitor clamped and cascaded H bridge type. They are having a more number of switches with less number of levels or more. Due to this it can provides a more switching losses and less accuracy. And also it can require more drivers for turn ON the switches, also difficulties in pulse width modulation. The proposed MLI is a new configuration in Flying Capacitor Multilevel Inverter (FCMI). The introduced MLI gives that it consists of less number of switches and gate drivers. And also it has features of voltage balancing property, purge the more dc source, double the output voltage levels, get better the output frequency range. The PWM control by using phase shift PWM. The simulations are made with help of PSIM simulation package and captivating all the parameters values.
HISTOMORPHOLOGICAL POSTNATAL DEVELOPMENTAL STUDY OF THE OVARIES OF THE LOCAL RABBITS ( Oryctologus Cuniculus )

This investigation was carried out to point out structural histomorphological changes that take place in the ovaries of female local rabbits at three different postnatal periods of their life that were kitten, immature and mature does. To conduct such project, 24 rabbits were collected (8 for each age) from the local breeders. Rabbits were euthanized, dissected and subsequently ovaries were collected and fixed with 10% neutral buffered formalin then subjected to routine processing such as dehydration, clearing, embedding and block preparation. Finally, sections of 6 μm were prepared and stained with hematoxylin-eosin and Masson’s trichrome stains. Gross findings showed two functional bilateral elongated triangular-shaped ovaries situated in the abdominal cavity suspended by mesovarian ligament with absence of true ovarian bursa. Microscopic findings revealed prominent structural changes in the ovaries of immature does compared to those of kittens and mature does indicated that immature does after the period of weaning face great developmental growth and changes. The data showed the presence of pre-ovulatory follicles in the mature does and no signs of ovulation because
Using Multiview to Identify Factors that Affect their Use in Electronic Learning Course

The important factors that affect Learning Management System (LMS) implementation by employing the theory of Multi-view 2 were studied. These can be used as a tool to analyze the problems of using e-learning in teaching and learning. The case study used the fundamental course named Information Technology for Life. Quantitative and qualitative research methods were used to answer the research question. Data was collected by following the Multi-view 2 framework representing the results in three dimensions: (i) technical perspective from a group of technicians, (ii) organizational perspective from administrators, and (iii) people perspective from a group of teachers and students. Results of the research could play an important role to support a decision of education leaders in developing information system plans, and to solve problems that occurred in learning systems in the educational
N ov 2 01 7 Unsupervised 3 D Reconstruction from a Single Image via Adversarial Learning

Recent advancements in deep learning opened new opportunities for learning a high-quality 3D model from a single 2D image given sufficient training on large-scale data sets. However, the significant imbalance between available amount of images and 3D models, and the limited availability of labeled 2D image data (i.e. manually annotated pairs between images and their corresponding 3D models), severely impacts the training of most supervised deep learning methods in practice. In this paper, driven by a novel design of adversarial networks, we have developed an unsupervised learning paradigm to reconstruct 3D models from a single 2D image, which is free of manually annotated pairwise input image and its associated 3D model. Particularly, the paradigm begins with training an adaption network via autoencoder with adversarial loss, which embeds unpaired 2D synthesized image domain with real world image domain to a shared latent vector space. Then, we jointly train a 3D deconvolutional network to transform the latent vector space to the 3D object space together with the embedding process. Our experiments verify our network’s robust and superior performance in handling 3D volumetric object generation from a single 2D image.
Strongly coupled N = 4 super Yang-Mills plasma on the Coulomb branch II : Transport coefficients and hard probe parameters

We study N = 4 super Yang-Mills theory on the Coulomb branch (cSYM) by using its Type IIB supergravity dual. We compute the transport coefficients, and hard probe parameters of N = 4 cSYM at finite temperature T . We use the rotating black 3-brane solution of Type IIB supergravity with a single non-zero rotation parameter r0 after analytically continuing r0 → −ir0, and in an ensemble where the Hawking temperature T and a scalar condensate < O >∼ r 0 are held fixed. We find that the bulk viscosity to entropy density ratio of the large black hole branch decreases with temperature and has a maxima around the critical temperature Tc while, for the small black hole branch, it increases with temperature. The other transport coefficients and parameters of hard probes, such as the conductivity, jet quenching parameter, drag force, and momentum diffusion coefficients of the large black hole branch increase with temperature and asymptote to their conformal value while, for the small black hole branch, they decrease with temperature.
EFFECT OF MULTIMEDIA PRINCIPLE ON VOCABULARY LEARNING AMONG SECOND LANGUAGE LEARNERS

This paper discusses the importance of vocabulary in language learning and the effect of Multimedia Principle in vocabulary learning. Vocabulary acquisition is an essential part of language learning since it is considered as one of the main components of language proficiency which determine how well learners read, speak, listen and write. The language used in language learning becomes more complex as students move from one level to the next. Having limited vocabulary often hinders students from mastering the four language skills. Generally, in the traditional way of learning a language, only words and their associated meanings in a text-only format are presented to students. However, with the development of technology, multimedia glosses such as visual text, spoken text and graphics manage to assist students in acquiring new vocabulary. Research in the area of multimedia instruction has yielded results that indicate that texts and graphics (Multimedia Principle) are more conducive to learning, rather than just text or graphics alone.
A Study on the Mobile Learning of English and American Literature Based on Wechat Public Account

This paper uses Edgar Dale’s Audio-visual Learning Theory and Jean Piaget’s Constructionist Learning Theory as the theoretical framework to conduct two control experimental tests and a questionnaire research to investigate students’ impression and expectations toward Wechat public account based mobile learning mode as well as its validity, advantages and shortcomings. The findings of the research are as follows: (1) students who use the WeChat public account based mobile learning mode can perform better in acquiring knowledge and passing examinations than non-users; (2) students’ mobile learning habits find a good basis for their acceptance of the new WeChat learning mode; (3) most students respond to the new WeChat learning mode with a positive attitude, and universities can introduce this mode into the course design; (4) this new WeChat learning mode helps students learn literature in the aspects of interest stimulation, ability improvement and literature content learning; (5) WeChat mobile learning is only an extension of the current form of learning and cannot replace the current traditional school education; (6) Mobile learning mode based WeChat public account is an important teaching aid for teachers in the aspects of information dissemination, interactive mode and updated contents; (7) The experience of improving the current mobile learning model of WeChat public account can be enriched from students’ feedback. It is hoped that WeChat mobile learning will efficiently activate students’ learning potentials and promote English and American literature teaching innovation.
The importance of ultraviolet and near infrared wavelength sensitivity for visual discrimination in two species of lacertid lizards

Male and female Lacertid lizards often display conspicuous coloration that is involved in intraspecific communication. However, visual systems of Lacertidae have rarely been studied and the spectral sensitivity of their retinal photoreceptors remains unknown. Here, we characterise the spectral sensitivity of two Lacertid species from contrasting habitats: the wall lizard Podarcis muralis and the common lizard Zootoca vivipara. Both species possess a pure-cone retina with one spectral class of double cones and four spectral classes of single cones. The two species differ in the spectral sensitivity of the LWS cones, the relative abundance of UVS single cones (potentially more abundant in Z. vivipara) and the coloration of oil droplets. Wall lizards have pure vitamin A1-based photopigments, whereas common lizards possess mixed vitamin A1 and A2 photopigments, extending spectral sensitivity into the near infrared, which is a rare feature in terrestrial vertebrates. We found that spectral sensitivity in the UV and near infrared improves discrimination of small variations in throat coloration among Z. vivipara. Thus, retinal specialisations optimise chromatic resolution in common lizards, indicating that the visual system and visual signals might co-evolve.
Fungus e plant interaction in fl uences plant-feeding insects *

Fungal infection of plants alters plant metabolism and therefore their chemistry, by either increasing levels of defence compounds or decreasing levels of nutrients. Such alterations in plants, in turn, influence the performance of the insects that feed on them. Pathogenic fungi live on plants as either biotrophs or necrotrophs. Both bioand necrotrophic fungi alter the physiologies of plants in distinctly different pathways. This article explores the patterns of relationships evident between insects and plants, the latter infected by biotrophic and necrotrophic fungi, using established examples from the vertically and horizontally transmitted biotrophic, endophytic fungi. A curious pattern evident in such interactions refers to the biotrophic, endophytic fungi that live in galls induced by the Cecidomyiidae (Diptera). The insects associated with necrotrophic fungi stand distinct from the patterns of interactions evident among insects, plants, and fungi. An understanding of the ecology of three-way interactions involving distantly related organisms, viz., insects, fungi, and plants, will bear long-term consequences in the better management of annual crop and perennial forest trees. A majority of previously published papers in the context of insecteplantefungus interactions liberally use the terms ‘mutualism’ and ‘symbiosis’, implicating the various benefits conferred on one or more of the participants. In the examples referred to, and the interacting contexts analyzed in this paper, what emerges is that the fungus is parasitically associated with the plant. In the eventuality of an insect interacting with the infected (1⁄4 parasitized) plant, the insect gains (e.g., gall-inducing Cecidomyiidae) or in occasional instances the plant gains (e.g., Epichlo€e infections of Poaceae). A unifying model for insecteplantefungus interacting systems is not readily apparent. The only possible explanation is the independent origins of insect behaviour in either preferring or rejecting the fungus-infected plants. This is possibly driven by specific environmental conditions, in which a specific funguseplanteinsect system would be operating. © 2017 Elsevier Ltd and British Mycological Society.
