A Cost-Efficient and Reliable Resource Allocation Model Based on Cellular Automaton Entropy for Cloud Project Scheduling

Resource allocation optimization is a typical cloud project scheduling problem: a problem that limits a cloud system’s ability to execute and deliver a project as originally planned. The entropy, as a measure of the degree of disorder in a system, is an indicator of a system’s tendency to progress out of order and into a chaotic condition, and it can thus serve to measure a cloud system’s reliability for project scheduling. In this paper, cellular automaton is used for modeling the complex cloud project scheduling system. Additionally, a method is presented to analysis the reliability of cloud scheduling system by measuring the average resource entropy (ARE). Furthermore, a new cost-efficient and reliable resource allocation (CERRA) model is proposed based on cellular automaton entropy to aid decision maker for planning projects on the cloud. At last, the proposed model is designed using Matlab toolbox and simulated with three basic cloud scheduling algorithm, First Come First Served Algorithm (FCFS), Min-Min Algorithm and Max-Min Algorithm. The simulation results show that the proposed model can lead to achieve a cost-efficient and reliable resource allocation strategy for running projects on the cloud environment.

Performance analysis of orthogonal optical chaotic division multiplexing utilizing semiconductor lasers

In this paper, we numerically investigate the performance of orthogonal optical chaotic division multiplexing (OOCDM) based on active–passive decomposition utilizing semiconductor lasers. To the best of our knowledge, it is the first time that two necessary conditions including chaotic synchronization condition and orthogonal condition of chaotic carriers are defined to quantify the performance of OOCDM. The chaotic characteristics of the output optical powers, including time traces, RF power spectra, and auto-correlation function, are numerically analyzed. The effects of spontaneous emission noise and the following internal and external parameter mismatch on the performance of OOCDM are analyzed in detail, which include gain saturation coefficient, photon lifetime, carrier decay rate, carrier number at transparency, differential gain, linewidth enhancement factor, and pumping current. The numerical results show that the proposed OOCDM system is robust towards spontaneous emission noise and parameter mismatch for certain relative mismatch ratios.

Network Nations: A Transnational History of British and American Broadcasting (review)

Reviewed by: Network Nations: A Transnational History of British and American Broadcasting Noah Arceneaux (bio) Network Nations: A Transnational History of British and American Broadcasting. By Michele Hilmes. New York: Routledge, 2011. Pp. 358. $44.95. In Network Nations (not to be confused with the similarly titled Network Nation by Richard John), Michele Hilmes tackles the histories of American and British broadcasting, subjects that have been explored many times. These two systems are typically cast in opposition to each other, with the British Broadcasting Corporation depicted, in broad strokes, as the stiff hand of the state, determined to make sure listeners eat their vegetables. The American broadcasting system, on the other hand, is said to be so dominated by advertising, popular music, and (most recently) bloviating talk-show hosts that any genuine public service from the medium is all but impossible. Hilmes argues that the best way to understand the British and American systems is to view them not in contrast but in conjunction. Network Nations is a well-researched, comprehensive account of the transnational influences that flowed in both directions across the Atlantic, focusing on the decades of the 1920s through the 1970s. There are many explicit instances of exchange between Britain and the United States, such as during World War II, when many personnel and much programming were shared. We are also reminded, for example, that much of famed journalist Edward R. Murrow’s early training came from the BBC. Hilmes is particularly attuned to the use of electronic media to preserve a national identity, a concern that was much stronger in England than America. Viewing the American and British broadcasting systems in conjunction calls attention to issues that could be glossed over otherwise. In her recounting of the origins of the BBC, Hilmes emphasizes that the centralized system of control, meant to enforce a particular view of British national character, was a deliberate reaction to the chaotic condition of early American radio. There was nonetheless a definite commercial imperative to the BBC’s original mission. The organization began as a consortium of radio manufacturers, determined to make sure there was a reliable over-the-air service that might compel listeners to purchase the new appliance. Commercialism was also present on British airwaves with the sponsored programming that originated from European stations at first, backed by American advertisers, and then from ships anchored just outside official national borders. The most significant strain of influence that flowed from east to west was the notion and definition of “public broadcasting.” In the 1930s, when U.S. reformers attempted to tamp down the commercial nature of American radio, the BBC was a model for what could be achieved. In the United States, there was also a burst of post–World War II activity in serious radio drama and documentary, and Hilmes indicates that much of the inspiration came from England. The BBC continued to inspire American efforts [End Page 951] to increase its public-service programming, culminating with the creation of the Corporation for Public Broadcasting in 1967. To paraphrase Hilmes, there is a reason that PBS speaks with a British accent. The transnational focus of this book is an admirable and welcome antidote to most works of media history. Scholars in this area have often lamented the resolutely national nature of most such research. This situation results from the significant influence that governments have on their respective media systems, and also the nature of national archives in general. Hilmes’s 1997 Radio Voices has inspired many radio historians, and it would certainly be a positive if this newer work had the same influence on the field. There is, however, the unavoidable financial barrier to doing such ambitious, border-spanning research, and faculty at many universities may lack the necessary resources. If Hilmes’s level of research proves difficult to imitate, perhaps it will be successful in calling for increased attention to transnational influences. This work will appeal to many readers, not only those who have a specific interest in the history of broadcasting. Scholars interested in the relationship between the state and technological development will find the book of value, as will those interested in the relationship between media and...

Realization of Sustainable Development of Tour Engineering Land: Guided by the Government and Participated by the Public

Tour engineering land is a special type of land utilization. However, at present academic circles don’t put plenty attention to tour engineering land and each related government department and plan unit also don’t emphasis on the problems arising from tour engineering land use. It causes that using and management of tour engineering land is in the chaotic condition. The spread of tour engineering land is increased and will lead to severe waste and damange of land resources. This is mutually contradictory with the tourism vigorous development. The paper creatively combines land utilization plan, land market management with traveling plan to construct the operation pattern of tour engineering land for its sustainable development.

Study on period doubling bifurcation in current-mode SEPIC converter

Choosing the current of the front inductor as control object, the discrete time model of single-ended primary-inductor converter (SEPIC) converter working in the discontinuous conduction mode (DCM) is established in this paper, and the stability of the fixed point is analyzed. By studying the phase portrait, power spectrum and bifurcation diagram of the circuitry, a special period-doubling bifurcation phenomenon is found in this circuitry. The circuit experiences period, double period, quadruple period and then double period, quadruple period, finally enters into chaotic condition. The experimental results accord with the simulation results, which confirms that the special period-doubling bifurcation exists in the SEPIC converter working in the DCM.

Anti-control and circuit implementation of discrete-time systems under limited regional conditions

In the Chen-Lai and Wang-Chen algorithm , the modular functions are both defined in (-∞,+∞). A modular function, however, in the implementation of electronic circuit, is more reasonable in line with the actual situation if it is defined in a finite region. We take for example the anti-control of a discrete time system, of which the modular function is sine function on the basis of a finite region. And in the sense of Li-Yorke, the chaotic sufficient condition and the rigorous theory proof are provided. As a result, ranges of specific circuit parameters can be determined by both the sufficient conditions resulting from the theorem, and a finite region defined by the device, or the constraint conditions of a dynamic range. Therefore, this provides a fundamental basis for the circuit design and its technology. Based on this method, the anti-control circuit of the discrete time system is designed, of which the modular function is sine function in a finite region. And the experimental results are given for confirming the feasibility of the method. The method presented in this paper can also be applied to the circuit implementation and the anti-control of a discrete time system, of which the modular function is other nonlinear function.

“Th’eternal Brood of Glorie Excellent”: Infants and the Battle for the Future in The Faerie Queene

Given the prominence of infants in The Faerie Queene—both literal children and questing “infant” scions of distinguished families—disappointingly little criticism has had anything to say about them. Even more disconcerting, most scholarship on the subject has focused almost exclusively on readings of separation anxiety and alienation; more extreme examples paint generation and reproduction themselves with broad brush strokes the color of disdain. Childhood becomes a tragicomic parallel to Hobbes’s memorable specter of the chaotic condition of humanity before establishing a government: “solitary, poor, nasty, brutish, and [of course] short.” It is now high time for a balanced reading of reproduction and children in The Faerie Queene. While Spenser’s infants may suffer from alienation and what contemporary psychoanalysis calls separation anxiety, those developmental struggles are crucial steps in the transformative process of the quest. The next generation is born into grave conflict, but generation itself is a good and necessary thing that imbues progeny with the power of their ancestors and recalls the necessity of future (re)generation in the constant imperative of dynastic renaissance. Spenser’s foundling children and infant knights are avatars of “th’eternal brood of glorie excellent” that will continue the allegorical struggle for the triumph of virtue when the current generation is dead and gone.

The Effect of Aspect on Soil Spatial Variability in Central Zagros, Iran

This study addressed the effect of aspect on spatial variability of some of soil physicochemical properties in Central Iran. Two north-facing and south-facing slopes were selected and 102 topsoil samples were randomly collected. Results showed that the spatial distribution and spatial dependency level of the same soil attributes were different in two aspects. Regarding to the kriged maps, only trends of soil pH and silt percentage were more or less similar for both aspects. Our findings suggest that local-scale soil variability in different aspects could grow unstably over time and bring about an unstable and chaotic condition for soil pedogenesis.

The Subversive Desire of English Renaissance Revenge Tragedy

The most important factor that made English renaissance revenge tragedy so popular at that time was not only the sensational violence and bloodshed on the stage but also its representation of the chaotic political and religious problems in the late Tudor Dynasty. People in the Tudor and Stuart Dynasty wanted effective government and religious stability, but they were not achieved. The contemporary dramatists criticized and mocked the chaotic political and social condition, using the setting of other countries, and satisfied the audience’s subversive desire. Revenge tragedy was the most effective means to deliver this political desire by characterizing the immorality of the ruling class and by maximizing the revenger’s suffering. Even though the revengers cannot avoid the destruction, their subversive madness and mockery could give off Dionysiac desire and pleasure beyond moral order. When we see the renaissance revenge tragedy in the perspective of Christianity, revenge tragedy can be interpreted within the God-centered conservative view. The Christian belief at that time prohibited private revenge. The protagonist of the renaissance revenge tragedy feels conflict between the private revenge and God’s providence. If he gives up his private revenge and depends on God’s justice and law of the country, he does not get the tragic end. However, if he commits private revenge, he cannot but undergo the destruction. Based on this view, revenge tragedy can be the good means to deliver the moral lesson, which emphasizes God's providence and justice ahead the revenger’s desire and emotion. However, renaissance revenge tragedy reveals the subversive desire which makes the God-centered morals and ruling order suspicious. The revenger is portrayed as a hero. He is not just the incarnation of revenge but the hero who reveals the reality of the corrupt power. The revenger’s painful choice and private revenge involve the political meaning that suspects and criticize God’s or the king’s justice. When the king and the law are not able to take the role of carrying out justice, the revenger’s private vengeance and destruction becomes the good means to bring the audience into the political recognition of social injustice.

An efficient framework of emergency response to facilitate disaster recovery for fire-damaged medical equipment – Case study at a large medical centre after a fire

The major role of disaster recovery management is to rapidly restore the chaotic condition to normal, which includes mitigation, preparedness, response, and recovery. To reduce secondary damage and loss, the recovery process must be facilitated. Information technologies (including network, web-based, computer, and related software tools) speed up the work process to rapidly deliver disaster information to the related department. In this paper, we share an experience that used a framework of emergency response, including a simple pre-operating process and a web-based information system, to effectively manage and control damaged medical equipment after a fire accident in a hospital operating room. This web-based information system was built in only 2 weeks and was used to manage a large amount of medical equipment affected by the fire. Since then, it effectively prevented the interruption of clinical work at 22 clinical units by supporting the reconstruction activities.

Dependence of entanglement dynamics on the global classical dynamical regime

We analyze the connections between the dynamical generation of continuous variable entanglement and the underlying classical trajectories in pairs of coupled oscillators. In the quantization of a periodic cycle, we find periodic entanglement which has twice the frequency of the corresponding classical motion. Such frequency doubling continues to hold true in the entanglement dynamics for a second model that exhibits a two-frequency orbit in the classical domain. In addition, the periodicity and the quasiperiodicity of the entanglement are found to be independent of the local classical dynamical behavior. Finally, in our third model, the entanglement production rate is found to be (i) higher in the chaotic regime and (ii) insensitive toward the choice of regular or chaotic initial condition in the mixed regime. In summary, we have illustrated through our sample models that the generation of dynamical pattern of entanglement can depend completely on the global classical dynamical regime without being influenced by the local classical behavior.

Entropy-based scheduling of resource-constrained construction projects

A method is presented for resource allocation and scheduling of resource-constrained projects by use of a measure of the projects' entropy. The entropy, as a measure of the degree of disorder in a system, is an indicator of a project's tendency to progress out of order and into a chaotic condition and it can thus serve to forecast a project's development. The entropy metric used in the analysis is based on the resource assignments per activity (required vs. assigned resource units).

The “Multiple Hormone Deficienc” Theory of Aging: Is Human Senescence Caused Mainly by Multiple Hormone Deficiencies?

In the human body, the productions, levels and cell receptors of most hormones progressively decline with age, gradually putting the body into various states of endocrine deficiency. The circadian cycles of these hormones also change, sometimes profoundly, with time. In aging individuals, the well‐balanced endocrine system can fall into a chaotic condition with losses, phase‐advancements, phase delays, unpredictable irregularities of nycthemeral hormone cycles, in particular in very old or sick individuals. The desynchronization makes hormone activities peak at the wrong times and become inefficient, and in certain cases health threatening. The occurrence of multiple hormone deficits and spilling through desynchronization may constitute the major causes of human senescence, and they are treatable causes. Several arguments can be put forward to support the view that senescence is mainly a multiple hormone deficiency syndrome: First, many if not most of the signs, symptoms and diseases (including cardiovascular diseases, cancer, obesity, diabetes, osteoporosis, dementia) of senescence are similar to physical consequences of hormone deficiencies and may be caused by hormone deficiencies. Second, most of the presumed causes of senescence such as excessive free radical formation, glycation, cross‐linking of proteins, imbalanced apoptosis system, accumulation of waste products, failure of repair systems, deficient immune system, may be caused or favored by hormone deficiencies. Even genetic causes such as limits to cell proliferation (such as the Hayflick limit of cell division), poor gene polymorphisms, premature telomere shortening and activation of possible genetic “dead program” may have links with hormone deficiencies, being either the consequence, the cause, or the major favoring factor of hormone deficiencies. Third, well‐dosed and ‐balanced hormone supplements may slow down or stop the progression of signs, symptoms, or diseases of senescence and may often reverse or even cure them. If hormone deficiencies and imbalances are the major causes of senescence, what then is the treatment? Crucial for the treatment of senescent persons is to make a correct diagnosis by making up an anamnesis of all symptoms related to hormone disturbances, conducting a thorough physical examination, and getting laboratory tests done such as serum and 24‐hour urine analyses. The physician should look not only for hormone deficiencies, including the mildest ones, but also for any alterations in hormone circadian cycles, and for the presence of any factors—nutritional, dietary, behavioral, lifestyle, environmental (including illumination and indoor, outdoor, or dietary pollutants)—that cause or aggravate hormone deficiencies. After completion of the detailed diagnostic phase and obtaining and analyzing the results of the tests, treatment can start. In general, before supplying hormones, all other factors that contribute to senescence should be eliminated. After that, supplements of the missing hormones can then be administered, carefully respecting an appropriate timing of their intake, and eventually recommending measures such as lifestyle changes to restore circadian rhythmicity.

Rezultat teh posegov so številni poskusi reformiranja pouka in krčenja števila ur latinskega in grškega jezika. Največji pritisk sta oba klasična jezika doživela v obdobju 1921-1926.

Impersonation, Autobiography, and Cross-Cultural Adaptation: Lee Kuo-Hsiu's Shamlet

Lee Kuo-Hsiu's 1992 Shamlet is a "sham" Hamlet that possesses three palimpsestical levels of signification as it rearranges Shakespeare's play. The first level is the parody of the Shakespearean text, where scripted technical errors and confusion prevail when a fictional Taiwanese theater company rehearses and performs Hamlet. The second level is (auto)biographical: the stories of the characters of the company portraying Hamlet reflect the chaotic condition of theatre making and living in contemporary Taiwan, where the economics of the arts are vexed and the political future of the island is unclear. At a third level, where the parody of the Western classical text and the autobiographical rendition of contemporary East Asian reality confront each other in scripted improvisations, a new Asian modernity emerges in the articulate voice of Lee Kuo-Hsiu.

Structure of Hamiltonian Matrix and the Shape of Eigenfunctions: Nuclear Octupole Deformation Model**The project supported by the “100 Person Project” of the Chinese Academy of Sciences and 973 Project under Grant No. G2000077400

The structure of a Hamiltonian matrix for a quantum chaotic system, the nuclear octupole deformation model, has been discussed in detail. The distribution of the eigenfunctions of this system expanded by the eigenstates of a quantum integrable system is studied with the help of generalized Brillouin–Wigner perturbation theory. The results show that a significant randomness in this distribution can be observed when its classical counterpart is under the strong chaotic condition. The averaged shape of the eigenfunctions fits with the Gaussian distribution only when the effects of the symmetry have been removed.

Unstable behavior of single-phase natural circulation under closed loop with connecting tube

Abstract The single-phase natural circulation in a single loop system has been studied by many researchers. In a multiple loop system, the characteristics of natural circulation are more complicated because of the interaction between the loops. In this study, the effects of the multiple loop on the natural circulation instability were investigated experimentally. As the simple multiple loop system, the toroidal loop with insulated connecting tube between both sides (θ-loop) was evaluated. The variation of flow regime in the θ-loop was almost the same as that in the single loop. However, the chaotic condition in an inclined θ-loop was narrower than that of inclined single loop. The flow and the pressure transfer in the connecting tube played an important role in the chaotic condition in the θ-loop.
