Renewable energy has a great importance for power generation as it does not use the fossils fuels. Energy generated from alternative energy sources are weather dependent. To generate a continuous power to meet the load requirements, Battery energy storage system are used. Power conversion process must be much efficient as possible to convert the DC stored energy into AC. This conversion process is usually done by the help of inverters. This paper gives the brief overview on three main categories of multilevel inverter like cascaded h-bridge, neutral point clamped and flying capacitor multilevel inverter and highlights their advantages which can also help the scholars to deeply explore the categories of multilevel inverter. Harmonic elimination is usually done by controlling the switching angles of the inverter. Among all the switching angles techniques, selective harmonic elimination pulse width modulation (SHEPWM) technique is widely used, that has also discussed in this paper. Furthermore, to eliminate the harmonics using SHEPWM, it has the set of nonlinear transcendental equations, these set of equations can be effieceintly solved by the optimization methods. The most efficient and reliable optimization method like particle swarm optimization has been discussed with multiple objective functions in this paper. This paper will help the scholars to understand the finest category of multilevel inverter for harmonic elimination in terms of efficiency and output quality.

This work employs the Brownian motion model in which observations are taken sequentially. The objective is to detect a two-sided change in the constant drift by means of a stopping rule. As a performance measure, an extended Lorden criterion is used. The goal is to minimize the worst-case detection delay subject to a constraint in the frequency of false alarms. In a companion paper, attention is drawn to a first category of 2-CUSUM rules for which the harmonic mean rule holds. It is further seen that a special class of 2-CUSUM stopping rules within this category, called drift equalizer rules, perform strictly better than non-equalizer rules, according to this specific performance measure.

Full textAbstract:
High-order harmonic generation is a powerful and sensitive tool for probing atomic and molecular structures, combining in the same measurement an unprecedented attosecond temporal resolution with a high spatial resolution of the order of an angstrom. Imaging of the outermost molecular orbital by high-order harmonic generation has been limited for a long time to very simple molecules, like nitrogen. Recently we demonstrated a technique that overcame several of the issues that have prevented the extension of molecular orbital tomography to more complex species, showing that molecular imaging can be applied to a triatomic molecule like carbon dioxide. Here we report on the application of such a technique to nitrous oxide (N2O) and acetylene (C2H2). This result represents a first step towards the imaging of fragile compounds, a category which includes most of the fundamental biological molecules.

Full textAbstract:
The thesis has been written on the basis of main architectural concepts and their application in real life within a historical context investigation. Main architectural concepts are represented in a harmony of architectural composition that deals with relations among form, structure and space in the unique art work. Genius loci play very important role in the architectural creation - it represents a special and extra-ordinary urban locality and its architectural value in the historical, geographical and cultural context. The origin of Ostravice village within the historical frame concept of Moravia domain is the topic of this thesis. Other historical documents gave information about Bruneswerde as the Brno Castle. That means Brno Castle had to be founded not in Brno (as it has been consid-ered for many years) but it was located in Beskydy at Ostravice. The sacred city – Civitas Dei had been located in Bruneswerde region in early ages as the centre of European culture, education and spiritual life. Civitas Dei – divine Jerusalem in the transcription of St. Augustine's book De civitate Dei – is not only glorification of God and religious fantasy. It is also one of significant clues for recognition of historical architecture. The depiction of unknown settlement from the book of unde-fined origin is a superb testimony about extinct architectural works. They are legible from cadastral maps. Brno Castle - residence of nobility and power served shelter to St. Vojtěch, St. Prokop, St. Václav and St. Ludmila as it is obvious for the mentioned picture. Three major temples, three com-position axes symbolized by three towers on coins are in analogical relation to Brno triangle of four saints - the Saint family of Brno temples. Powerful ambitions of Brno City principals and clergy are inscribed into the urban structure in the way of composition relations which are legible to them who devoted themselves to the mystery of harmony. The absence of historical continuity affects personal attitudes and also identity of the whole community. The architecture truly reflects the past state of polis and it is eloquent even after its death. The architectural composition relations influence the natural environment for long time, longer than the architectural work existence. The geometric order of Renaissance Brno existence has not been in attention of architects so far. The features were discovered in characteristic paintings by Albrecht Durer. They are evidently secret works of the genius. A meaningful collaborator and follower in the extensive project was also his friend Jan Čert from Brno and lately from Vienna. His noble genealogy played a significant role in history of Silesia and Moravia for centuries. It is tendency to consider him as Austrian or even German architect. It is because of the fact that the genealogy tree of his noble family had roots in Moravia. It is supposed that Durer with Jan Čert´s support created the extraordinarily monumental architectural and urban works in Brno. A remarkable consensus in the urban composition of two squares and transition of traditional urban structure of Ostravice Civitas Dei into the modern Brno is also confirmed due to the identification of noble creators and owners, who were at the foundation, transformation and extinction of elements of the Moravian urban structure.

Dissertação de Mestrado em Engenharia Electrotecnica e de ComputadoresEmbora pouco frequente e por acidente, o nervo laríngeo recorrente pode ser seccionado durante a cirurgia tiroideia, o que ocasiona paralisia da corda vocal homolateral. Até hoje não há um método eficaz para o reconstruir, porque o nervo tem características únicas, uma vez que possui fibras adutoras e abdutoras. Se for feita a sua reconstrução com sutura dos topos, algumas fibras adutoras unem-se a abdutoras do outro lado, o que provoca movimentos discinérgicos e descoordenados das cordas vocais. Através de uma nova técnica cirúrgica pretende-se ultrapassar este problema tendo sido para isso escolhida a cabra como modelo animal. As cabras foram operadas e antes e após a cirurgia foram realizados registos do balido para identificar o momento de uma eventual regeneração das fibras nervosas com a consequente recuperação da voz da cabra. Uma das principais contribuições deste trabalho, para além do estudo de um conjunto de métodos e parâmetros que normalmente se utilizam na voz humana, prende-se na contribuição como um auxiliar tecnológico para validar a técnica cirúrgica. Na identificação das alterações na voz das cabras ao longo do período de recobro foram utilizadas avaliações objetivas e subjetivas com a adaptação de uma norma aplicada à voz humana: Comparison Category Rating (CCR). Dada a quantidade de dados envolvidos e a falta de referências na área no que diz respeito ao som da cobaia estabelecida para validar a técnica cirúrgica, o balido da cabra, optou-se por tentar procurar semelhanças a partir da abordagem subjectiva de forma a encontrar uma classe de amostras cujos resultados da avaliação objectiva fossem congruentes com os resultados do método subjectivo seguido. O software Praat serviu para estudar as características da voz das cabras, como o Jitter e o Harmonics to Noise Ratio (HNR). Como resultados da cabra de reconstrução 49, conclui-se que o maior número de sujeitos inquiridos (93,5%) respondeu que a 3ª amostra pós-operatória é a que mais se assemelha com a amostra pré-operatória e a maioria dos indivíduos inquiridos (87,09%) afirma que a voz evolui no sentido da amostra pré-operatória. Referente à cabra 47, não se obteve uma ”melhor” amostra, como esperado pelos resultados médicos.
Although infrequent, and by accident, the recurrent laryngeal nerve can be sectioned during thyroid surgery, causing paralysis of the ipsilateral vocal cord. Nowadays, there is not an effective method to reconstruct, because the nerve has unique characteristics, because it has fiber and water mains abductors. If its reconstruction will be made with suture of the tops, some adductor fibers join the abductors on the other side, resulting in uncoordinated movements and dyssynergia of the vocal cords. Through a new surgical technique aims to overcome this problem have been chosen for this goat as animal model. The goats were operated and before and after surgery were performed bleating records to identify the timing of a possible regeneration of nerve fibers with consequent recovery of voice of the goat. A major contribution of this work beyond the study of a set of methods and parameters are normally used in the human voice, concerns the contribution as a processing aid to validate the technique. In identifying the changes in the voice of the goats during the period of recovery room were used objective and subjective evaluations with adaptation of a standard applied to the human voice: Comparison Category Rating (CCR). Given the amount of data involved and the lack of references in the field with regard to the sound of the goats established to validate the surgical technique, it was decided to try to find similarities from the subjective approach in order to find a class sample results of objective evaluation were congruent with the subjective results of the method followed. The Praat software was used to study the characteristics of voice of the goats, like Jitter and the Harmonics to Noise Ratio (HNR). The results of reconstruction of goat 49, concludes that the greater number of subjects surveyed (93.5%) responded that the 3rd postoperative sample that is most similar to the sample pre-operative and most of those interviewed (87.09%) states that voice heading in the direction of the sample pre-operative. Referring to the goat 47, there was no one ”best”sample, as expected by the medical outcomes.

Muhammad Iqbal’s The Reconstruction of Religious Thought in Islam belongs in the category of modern Muslim reformist works, which address, issues of a practical nature faced by Muslims in the social, political, and legal spheres. Iqbal’s Reconstruction analyzes these issues at a deeper, philosophical level, seeking to transform minds and outlook before proposing specific solutions to specific problems. The primary aim of the Reconstruction is to rejuvenate Muslim thought in the modern context. To this end, it enters into a critical engagement with the intellectual, religious, spiritual, and scientific thought of the Muslim and Western traditions, inquiring into the prospects of bringing into harmony, from an Islamic standpoint and in an Islamic setting, tradition and modernity, religion and science. The legacy of the Reconstruction is its invitation to Muslims to reassess the entire Islamic tradition, being fully cognizant of modern developments in thought without breaking with their own past.

Full textAbstract:
This chapter argues that the category of religion eludes traditional Chinese thinking. It outlines the periods of harmony between official Buddhism, Daoism, and Confucianism, commenting on the historical reverence for martial gods and practices of religiously sanctioned human sacrifice and self-mortification. The amorphous religious identity characteristic of China offers a convenient starting point for the analysis. Chinese clerics have been conscious of their religious distinction to the extent of competing with others. The policy has been a major source of friction between the People's Republic of China and the Catholic Church. The Chinese martial art is a multifaceted system of physical and mental self-cultivation that combines military, therapeutic, and religious goals within the same training routine. The imagination of Daoist immortality, the cosmology of the Supreme Ultimate, and the vocabulary of Buddhist enlightenment has been equally tackled to discuss the practitioner's mystical experience.

This chapter focuses on the harmonic and formal procedures found in rock’s verse sections. To begin, the chapter divides the category of verses into sectional verses—those that contain a complete harmonic structure ending with a cadence—and initiating verses—those that contain only the beginning of a harmonic structure, setting up a continuation in later sections. Sectional verses exhibit several common thematic layouts, including periods, srdc, twelve-bar blues, and small aaba, all of which have particular harmonic layouts. The chapter includes a discussion of refrains, in particular distinguishing them from choruses.

This chapter looks at the musical structure, scales, and chords used by Charley Patton, considering the bluesman's “elementary blues.” In this category belong pieces whose harmonic material is more reduced than in the most widespread classical blues formula, namely the three-chord pattern (3C) with two textual verses (2V). One must keep in mind that the 3C2V pattern produces various canonical forms. The chapter then connects that pattern with the tonal scale using selections from Patton's Yazoo double album.

The chapter starts with the discussion of the aesthetic category of “humorous music,” which emerged in the last decade of the eighteenth century, and links it to the theory of multiple agency, proposed by Edward Klorman (2016). There follow two case studies of hypermetric manipulations in the first movements of Haydn’s string quartets Op. 50 No. 3 and Op. 64 No. 1. These analyses reveal how such manipulations act in concert with ingenious deployment of musical topics and contrapuntal-harmonic schemata, and how they affect musical form. The chapter closes with remarks about the role of the first violinist in Haydn’s string quartets.

Chapter 6 deals with the connection between the structure and properties of solids as revealed and studied in polymorphic systems. The subject is divided into properties that depend on the one hand on the bulk—that is, the three-dimensional arrangement of the molecules and the interactions among them—and on the other hand the consideration of the crystal as an “oriented gas” serving to act as a matrix for the molecules to permit the study of molecular properties. Among the properties described in the former category are electrical conductivity, organic magnetic materials, photovoltaicity and photoconductivity, second harmonic generation, chromoisomerism, photochromism, thermochromism and mechanochromism, and the mechanosalient effect. The latter category includes a discussion of spectroscopic studies (infrared, Raman, and ultraviolet/visible), excimer phenomena, time-resolved studies of excited states, photochemical reactions and thermal and gas reactions, along with a variety of emission phenomena. The chapter closes with a brief survey of rapidly emerging and developing high pressure studies

Full textAbstract:
The living state of matter, while obviously obeying physical and chemical laws, does exhibit some peculiar features which, taken altogether, distinguish it from the rest of the natural world. As discussed at length elsewhere [16, 18], these include, among others, hierarchical organization, individuality, invention, and homeostasis. One key category which was introduced by Waddington [94] is homeorrhesis. Homeorrhesis is the dynamical version of homeostasis and it may be defined as the capacity of living systems to maintain their harmonic dynamical networks through continuous change in response to external and internal noise. In the present chapter, we will discuss, in the light of recent interdisciplinary data, the relationship between noise and self-organization. We propose, as a new feature specific to living systems, the capacity to integrate into flexible and versatile networks a portion of noise of internal and external origin (correlated information), and to utilize it to counteract the disrupting effect of the remaining noise. The analysis will be carried out at the levels of DNA and of organized networks, and will also be tackling the problem from the point of view of the relationship between increases in organismal complexity and entropy levels at the evolutionary scale…. Present-day genomes are the results of evolution, and DNA may be considered as an archive of past events. We use as a working hypothesis the almost unanimously accepted concept of interplay between selection as it fixes "useful" sequences, and mutation-genetic drift forces as they generate noise and continuously shuffling of genomes. Studies on structure and function of genomes have been increasing at a very fast rate following the extraordinary progress in sequencing techniques and, consequently, in GenBank whole genome sequences are available of a number of bacteria, Archaea, viruses, and eukaryotes. DNA content per cell has been increasing during evolution, more recent species having, in general, larger genomes than ancestral ones. This, however, is only a rough approximation of reality. A better analysis of the data tells us that while prokaryotes (bacteria and Archaea) have small genomes ranging from 500,000 base pairs (bp) to 5 million bp, an abrupt increase has occurred in eukaryotes. In this large group, a unicellular organism like Saccharomyces cerevisiae has a 12-million-bp genome, while multicellular organisms range from around 100 million to several billion bp.

The epilogue sets the book off against previous studies of the subjunctive. It summarizes the main results and derives rewarding topics for future studies from them. The frequency rise of subjunctives in main clauses at the end of the 14th century after its previous decreaseinvites an investigation of this construction type in the following periods. The hypothesis of the importance of the simplification of the verbal paradigm for the frequency decrease of the subjunctive is challenged by the observation that third person singular subjunctives contributed most to the survival of the category mood in all periods. This may be only one of the outstanding features of this form of the verbal paradigm. Changing genre conventions were found to correlate with changes in subjunctive use, and this opens a new perspective for genre studies. The inclusion of the category modality in the definition of the subjunctive allows answers to many questions about subjunctive use, among them its different development in individual construction types and adverbial clauses as well as the role it plays in periods of highly valued modal harmony.

This chapter explores various methods for thoroughly learning a score. Although not the focal point of this book, having a well-prepared score before stepping onto the podium will provide better opportunities to design engaging and productive rehearsals. Each broad category of score study (such as text, time, architecture, harmony, etc.) includes sample brain-compatible rehearsal strategies. The chapter concludes with a consideration of frequently asked questions regarding how best to prepare a score for rehearsals and performance. Topics include methods for marking a score, how much or how little to listen to recordings, use of the International Phonetic Alphabet, and how to introduce a new score to your ensemble.

Full textAbstract:
This chapter deals with the frequency development of the subjunctive and its competitors, namely indicatives and modal constructions, in adjectival relative clauses in the historical periods Old English (OE), Middle English (ME), and Early Modern English (EModE). Additionally, it discusses the linguistic and extralinguistic parameters influencing their distribution across these periods. The analysis of a corpus comprising nearly 3,000 relative clauses reveals that the subjunctive in adjectival relative clauses died out in the 16th century, that it was best preserved in text category STA containing legislative texts, and that it was favoured in combination with wh-relative markers and in constructions characterized by modal harmony, i.e. in combination with matrix clauses with verbal syntagms expressing root modality.

Capturing a level of modeling of the flow inside a multi-stage turbomachine, such as unsteadiness for example, can be done at different degrees of details, either by capturing all deterministic features of the flow with a pure unsteady method or by settling for an approximated solution at a lower computational cost. The harmonic methods stand in this second category. Amongst them the “Nonlinear Harmonic Method” from He revealed the most efficient. This method consists of solving the fully nonlinear 3D steady problem and a linearized perturbation system in the frequency domain. As it has been shown by the authors that the circumferential variations exhibit a harmonic behavior, it is proposed here to adapt this method to the through-flow model, where the main nonlinear system would be the common throughflow equations and the auxiliary system would give access to the circumferential stresses. As the numerical local explicit impermeability conditions are unsupported by Fourier series, the adaptation of this technique to the throughflow model passes through a reformulation of the blade effect by a smooth force field as in the “Immersed Boundary Method” from Peskin. A simple example of an inviscid flow around a cylinder will illustrate the preceding developments, bringing back the mean effect of the circumferential non uniformities into the meridional flow.

Iwan models have had some exposure recently in modeling the nonlinear response of individual joints. This popularity can be ascribed to their mathematical simplicity, their versatility, and their ability to capture the important responses of mechanical joints under unidirectional loads. There is a lot of history to this category of model. Masing explored kinematic hardening of metals with a model consisting of ten Jenkins elements in series. Soon after, Prandtl explored the behavior of a continuous distribution of such elements. Ishlinskii explored the mathematical structure of such continuous distributions. Much more recently, Iwan demonstrated practical application of such models in capturing various sorts of metal plasticity. Among the features that make such models interesting is a simple relationship between the asymptotic nature of the integral kernel at small values and the power-law relation between force amplitude and dissipation per cycle in harmonic loading. Iwan provided several differential equations for deducing the kernel from force-displacement relations. Segalman and Starr devised methods for deducing kernels from force-displacement curves of arbitrary Masing models. This is illustrated to generate a BPII model equivalent to the Ramberg-Osgood plasticity model. The Segalman-Starr relationship is used to find relationships among several other plasticity models.

Parallel manipulators, compared to serial manipulators, have some interesting properties, such as high stiffness, low inertia, high velocity, good accuracy and large payload capacity. Thus, parallel manipulators, especially the ones with one translation and two rotations as outputs (1T2R), are being increasingly studied. The 3PRS mechanism is a very typical example of this category, but it has accuracy problems caused by the parasitic motion, and low orientation capability. To overcome these problems, new mechanisms are being studied, such as the 2PRU-1PRS manipulator. As the 3PRS manipulator, the degrees of freedom of the 2PRU-1PRS are one translation along the Z-axis and two rotations about the X- and Y-axes. The advantages are that the parasitic motion appears only in one direction instead of in three and that the orientation capability is higher. In this paper we present the design of a 2PRU-1PRS mechanism suitable for vibration tests. In order to do this, we develop a code with an intuitive GUI (graphical user interface) that, for given variable limits, solves the inverse kinematic and dynamic problem for all the variable combinations and obtains the combination that consumes less power for an harmonic trajectory. Taking the simulations results into account, we propose a design that fulfils all the requirements for vibration tests in the three axes.

Reports from onshore E & P activities in Nigeria have shown that operating in the Niger Delta region poses some of the toughest challenges in the world. This region has witnessed a spate of attacks on oil and gas facilities, staff and contractors. Consequently, major oil and gas players have to contend with complex operational uncertainties due to increase pressure from the local communities for improved environmental control measures. To effectively de-risk this region of this category of operational uncertainties, the industry must begin to see environmental performance as not only a measure of how well she can comply with existing environmental regulations, but also as a measure of how well she can pre-empt environmental pressures as well as maintain constant harmony with all concerned stakeholders and seeing herself as responsible to the environment with a view to improve performance. In this project, we have been able to develop SMART* models based on continuous consultation, integrated management approach and continuos improvement attitude (CIA). With a good FOCUS* approach, this will help in safe and effective operations, pre-empt pressures, maintain harmony with local communities and effectively manage operational disturbances within complex environmental settings like the Nigerian Niger Delta area. Finally, we are of the opinion that every industry that seeks to remain efficient and relevant in this millennium should constantly be looking for ways of becoming more environmentally responsible — because no business can call itself efficient if it threatens the environment within which it operates. • SMART is an acronym for Specific, Measurable, Achievable, Realistic and Time Bond. • FOCUS is an acronym for Fair, Objective, Consistent, Unbiased and Succinct.

Full textAbstract:
In this paper, we explore how sonic features can be used to represent network data structures that define relationships between elements. Representations of networks are pervasive in contemporary life (social networks, route planning, etc), and network analysis is an increasingly important aspect of data science (data mining, biological modeling, deep learning, etc). We present our initial findings on the ability of users to understand, decipher, and recreate sound representations to support primary network tasks, such as counting the number of elements in a network, identifying connections between nodes, determining the relative weight of connections between nodes, and recognizing which category an element belongs to. The results of an initial exploratory study (n=6) indicate that users are able to conceptualize mappings between sounds and visual network features, but that when asked to produce a visual representation of sounds users tend to generate outputs that closely resemble familiar musical notation. A more in-depth pilot study (n=26) more specifically examined which sonic parameters (melody, harmony, timbre, rhythm, dynamics) map most effectively to network features (node count, node classification, connectivity, edge weight). Our results indicate that users can conceptualize relationships between sound features and network features, and can create or use mappings between the aural and visual domains.
