El objetivo de este paradigma es convertir los objetos que nos rodean en objetos inteligentes de forma tal que, comunicándose a través de Internet, puedan percibir lo que sucede en su entorno y poder reaccionar frente a ello. Se han llevado a cabo numerosos trabajos en materia de estandarización para este paradigma como, por ejemplo, protocolos de comunicación, topologías de red y arquitecturas software de alto nivel que consideran, por sobre todas las cosas, cómo integrar todas las piezas de una solución de Internet de las Cosas en un solo sistema. Sin embargo, no se han identificado arquitecturas de software para la construcción del software de un objeto inteligente que describa los componentes básicos que se deben incluir. En este trabajo se propone una arquitectura de referencia para la construcción de objetos inteligentes en Internet de las Cosas cuyo objetivo es que los ingenieros de software tengan una estructura en la cual basarse y poder reutilizar.

    Investors are a heterogeneous group, they may be large or small, rich or poor, expert or lay man and not all investors need equal degree of protection (Mayya, 1996). An investor has three objectives while investing his money, namely safety of invested money, liquidity position of invested money and return on investment. The return on investment may further be divided into capital gain and the rate of return on investment as interest or dividend. Among all investment options available, securities are considered the most challenging as well as rewarding. Securities include shares, debentures, derivatives, units of mutual funds, Government securities etc. An investor may be an individual or corporate legal entity investing funds with a view to derive maximum economic advantage from investment such as rate of return, capital appreciation, marketability, tax advantage and convenience of investment.The Capital market facilitates mobilization of savings of individuals and pools them into reservoir of capital which can be used for the economic development of a country. An efficient capital market is essential for raising capital by the corporate sector of the economy and for the protection of the interest of investors in corporate securities. There arises a need to strike a balance between raising of capital for economic development on one side and protection of investors on the other. Unless the interests of investors are protected, raising of capital, by corporates is not possible. Like, the primary objective of a senior citizenís asset allocation is the generation of regular income.

A pesquisa objetiva discutir a cidade inteligente como uma reterritorialização do espaço das cidades, pelo exame conceitual de território, territorialidade, desterritorialização e reterritorialização. A justificativa está calcada na busca contemporânea por soluções aos problemas sociais, econômicos e culturais que as cidades enfrentam. A problemática nos induz a responder se as cidades inteligentes, ao criarem soluções, redefinem as formas e funções do espaço e por si constituem uma reterritorialização. A metodologia empregou a pesquisa documental e empírica, com revisão conceitual de autores meritórios nos temas como Komninos (2008, Haesbaert (2004, Raffestin (1993 e Sack (1986. A pesquisa apresenta as respostas à problemática de que o processo de desenvolvimento urbano propagado pelas cidades inteligentes é capaz de redefinir o uso e as ocupações dos espaços locais, regionais e nacionais, ensejando transformação territorial e, dessarte, uma reterritorialização. Abstract Smart cities are forms of appropriation of urban space based on the use of three intelligences – human, collective and artificial – and that implies territorial transformations. The research aims to discuss the smart city as a reterritorialization of all urban space through the conceptual examination of territory, territoriality, deterritorialization and reterritorialization. The justification is grounded in the contemporary search for solutions to social, economic and cultural problems facing cities. The problem leads us to respond if smart cities by creating solutions redefine the forms and space functions and by itself is a reterritorialization.

    1994-01-01

    Photoelectron spectroscopy is regarded as the most powerful means since it can measure almost perfectly the occupied electron state. On the other hand, inverse photoelectron spectroscopy is the technique for measuring unoccupied electron state by using the inverse process of photoelectron spectroscopy, and in principle, the similar experiment to photoelectron spectroscopy becomes feasible. The development of the experimental technology for inverse photoelectron spectroscopy has been carried out energetically by many research groups so far. At present, the heightening of resolution of inverse photoelectron spectroscopy, the development of inverse photoelectron spectroscope in which light energy is variable and so on are carried out. But the inverse photoelectron spectroscope for vacuum ultraviolet region is not on the market. In this report, the principle of inverse photoelectron spectroscopy and the present state of the spectroscope are described, and the direction of the development hereafter is groped. As the experimental equipment, electron guns, light detectors and so on are explained. As the examples of the experiment, the inverse photoelectron spectroscopy of semimagnetic semiconductors and resonance inverse photoelectron spectroscopy are reported. (K.I.)

    Inverse limits provide a powerful tool for constructing complicated spaces from simple ones. They also turn the study of a dynamical system consisting of a space and a self-map into a study of a (likely more complicated) space and a self-homeomorphism. In four chapters along with an appendix containing background material the authors develop the theory of inverse limits. The book begins with an introduction through inverse limits on [0,1] before moving to a general treatment of the subject. Special topics in continuum theory complete the book.

    Intuition suggests that corporate investment should be decreasing in financing constraints. We show that even when financing is obtained using a standard debt contract and there is symmetric information between the firm and outside investors, the relation is actually U-shaped. We thus provide a new...... theoretical explanation for the recent empirical findings of Cleary et al. (2007). We split up the endogenously implied financing costs and propose a trade-off between expected liquidation costs and second-best investment costs. For rather unconstrained firms, the risk of costly liquidation dominates the cost...

    Full Text Available Ha llegado a su madurez la V Generación y con ello sus expresiones: la inteligencia artificial (1-2, los sistemas con el apoyo de conocimientos (3 y la ingeniería de software (4. En Colombia poca acogida parece tener. Es que los conocimientos constituyen un salto paradigmático hacia un nuevo orden mundial: el paso de la Sociedad de la Información a la Sociedad del Conocimiento. No es difícil de colegir la implicación de nuevas generaciones de sistemas de información y aunque la inmensa mayoría de gerentes no quieren saber de nuevos lenguajes ni reprogramaciones, aquí describiremos cómo es posible desarrollar e implementar un sistema inteligente de información gerencia. El concepto de "inteligente" se refiere a la viabilidad de tener un determinado grado de autonomía decisional, un evidente mejor desempeño, una capacidad real de adaptarse a las condiciones particulares de un usuario, el reconocer y generar un plan de trabajo al ejecutivo y en especial por el soporte a las decisiones, lo cual no significa la posibilidad de "reemplazar" al ejecutivo en esta labor, sino por el contrario constituirse en un sistema asistente del ejecutivo. Una innovación en esta arquitectura la constituye la tutoría experta en línea, que constituye un espacio para posibilitar el "entrenamiento gerencial" in situ y además la incorporación de técnicas de aprendizaje maquinal que funcionen en la práctica. Lo anterior significa que UN-SEEGSI pretende ser un ambiente de aprendizaje dual: donde se debe dar un aprendizaje vivencial por parte del usuario y donde debe aprender la máquina en forma subrepticia.

    The mineral price assigned in mining project design is critical to determining the economic feasibility of a project. Nevertheless, although it is not difficult to find literature about market metal prices, it is much more complicated to achieve a specific methodology for calculating the value or which justifications are appropriate to include. This study presents an analysis of various methods for selecting metal prices and investigates the mechanisms and motives underlying price selections. The results describe various attitudes adopted by the designers of mining investment project, and how the price can be determined not just by means of forecasting also by consideration of other relevant parameters.

    In a traditional Black–Scholes market we develop a verification theorem for a general class of investment and consumption problems where the standard dynamic programming principle does not hold. The theorem is an extension of the standard Hamilton–Jacobi–Bellman equation in the form of a system of non-linear differential equations. We derive the optimal investment and consumption strategy for a mean-variance investor without pre-commitment endowed with labor income. In the case of constant risk aversion it turns out that the optimal amount of money to invest in stocks is independent of wealth. The optimal consumption strategy is given as a deterministic bang-bang strategy. In order to have a more realistic model we allow the risk aversion to be time and state dependent. Of special interest is the case were the risk aversion is inversely proportional to present wealth plus the financial value of future labor income net of consumption. Using the verification theorem we give a detailed analysis of this problem. It turns out that the optimal amount of money to invest in stocks is given by a linear function of wealth plus the financial value of future labor income net of consumption. The optimal consumption strategy is again given as a deterministic bang-bang strategy. We also calculate, for a general time and state dependent risk aversion function, the optimal investment and consumption strategy for a mean-standard deviation investor without pre-commitment. In that case, it turns out that it is optimal to take no risk at all.

  1. Managerial Stock Compensation and Risky Investment

    2009-06-01

    Full Text Available This study analyzes the relationship between the mix of CEO equity-based compensation, namely stock options and restricted stock, and firms' risky investment. In general, the theory suggests that long-term compensation aligns CEOs' and shareholders' interests by inducing the managers to undertake risky investment, which has a positive impact on longterm well-being of the firm. However, as my results show, it is important to distinguish between types of awards since they can have different effects on the riskiness of the firm. In this respect, I answer the question how are different types of stock based compensation related to the executives' determination to increase or not the intensity of the firm's risky investment? I find that awarding the CEOs preponderantly with stock options positively affects the firm's level of R&D investment. Conversely, a higher proportion of restricted stock in the CEO's compensation is related to lower investment in (risky R&D. The inverse relation of causality also holds. Firms that make intensive R&D investments are more likely to award their CEOs with more stock options relative to restricted stock. Overall, the results are consistent with the theoretical prediction, in that the managerial compensation scheme plays an important role in determining the level of R&D investment.

    Ph. D. Student Ioana - Julieta Josan

    2012-05-01

    Full Text Available Once with the development of the human capital theory, the education received an economic value. Leading theorists and specialists in the field have shown that the remarkable economic effects of the investments in education influence the chances of acquiring a job and earnings, demonstrating how the theory justifies such an investment. At the hand, the allocation of resources in human capital brings performance and benefits to companies investing in their employees. Also, the investment in human capital is strategic for any country that seeks to create a knowledge economy. Considering the above arguments, the aim of this paper is to highlight the characteristics of investment in human capital, the types of investment, the factors of education investment and the entities interested in investing and their benefits.

  11. Inverse Statistics and Asset Allocation Efficiency

    Science.gov (United States)

    Bolgorian, Meysam

    In this paper using inverse statistics analysis, the effect of investment horizon on the efficiency of portfolio selection is examined. Inverse statistics analysis is a general tool also known as probability distribution of exit time that is used for detecting the distribution of the time in which a stochastic process exits from a zone. This analysis was used in Refs. 1 and 2 for studying the financial returns time series. This distribution provides an optimal investment horizon which determines the most likely horizon for gaining a specific return. Using samples of stocks from Tehran Stock Exchange (TSE) as an emerging market and S&P 500 as a developed market, effect of optimal investment horizon in asset allocation is assessed. It is found that taking into account the optimal investment horizon in TSE leads to more efficiency for large size portfolios while for stocks selected from S&P 500, regardless of portfolio size, this strategy does not only not produce more efficient portfolios, but also longer investment horizons provides more efficiency.

    Knuutinen Reijo

    2017-12-01

    Full Text Available Taxes have become an issue of corporate social responsibility (CSR, but the role of taxation is to some extent an ambiguous and controversial issue in the CSR framework. Similarly, another unclear question is what role investors who are committed to sustainable and responsible investment (SRI see taxes as having on their environmental, social, and governance (ESG agenda. Corporate taxes have an inverse relationship with the return of the investors: taxes paid directly affect what is left on the bottom line, reducing the return of investors. However, investors are now more aware of tax-related risks, which can include different forms of reputation risk. Corporate tax planning may increase the returns, but those increased returns are riskier. This study focuses particularly on the relationship between SRI and taxation. We find that tax matters are considered to be on the ESG agenda, but their role and significance in the ESG analysis is unclear.

    (conventional or intelligent) is possible to get more power generation than if we use the automatic methods based on feedback MW control. Consequently, the financial benefit due to the MW generated along a period of 2 months, is equivalent to return the investment required if the CCPP would had been repowered. Test also showed that with the fuzzy based SGC is possible to get a 'little more' power generation than if we use the PID based SGC. The development and implementation of the SGC was made in three phases: First Phase: Upgrading of the simulation dynamic mathematical model and implementation in a new software platform based on LabWindows/CVI. Second Phase: Design, implementation and testing of the PID based SGC. Third Phase: Design and implementation and testing of the Intelligent SGC, based in fuzzy logic.

  3. INVESTMENT FUNDS IN ROMANIA

    Full Text Available I chose this topic because my goal was to capture in detail all aspects of the evolution of investment funds under the influence of factors leading to globalization of the banking financial market. Main motivation was that I proposed to present in an original manner the concept of investment in mutual funds by the thoroughness of the following points: the different types of investment funds from Romania, the advantages, the risks and the specific costs of the investment in mutual funds and the effects of the financial crisis on the industry of the investment funds on the national level. The financial crisis and the risk of infecting the global economy affected the taste of risk of the investors and their request for the investment fund, determining the orientation of the investors to the funds with a lower risk – the diversified funds, the funds of bonds and the monetary funds. I considered important the theoretical approach of the concept of investments in investment funds because they are a barometer of the macro economical stability, in case the economical increase is positive on the macro economical level the investments in investments funds are increasing too. In Romania the market of the mutual funds is at an incipient level, but with potential and perspectives of development. Due to the bankruptcy of FNI in the beginning of the years 2000 and due to the absence of a clear legislation regarding the calculation of the unitary value of the net asset and the control of the activity developed by the investment funds, the development of the industry of the investment funds had to fight against the crisis of credibility generated by these events. The convergence of the Romanian economy to the European standards will attract also a modification of the structure of the financial investments of the individuals, by an increase of the investments in funds. In the world the investment funds are preferred by the investors for their advantages

Although the rate of investment into real sectors of Russian economics mid 2000 was higher compared to the previous period, annual investment amounts were much lower than in 1990. At present, highest investment amounts are directed to industry extractive branches and to the commerce. Amounts invested to various economy branches do not correspond to their contribution to the country’sGross Added Product; particularly underinvested are manufacturing industry branches. At present, foreign share in the country economy total investment makes 15–18%. Recently, most interesting for foreigners was investment to machine-building branches with overwhelming part (for example, 90% in 2007–2008 of foreign investment into the machine-building industry being directed to creation of new automobile plants. Today, first place in the list of foreign investors’ preferences in Russia is taken by the machine-tool construction sector.

    Full Text Available We construct a comprehensive measure of overall investment banking competitiveness for follow-on offerings that aggregates the various dimensions of competition such as fees, pricing accuracy, analyst recommendations, distributional abilities, market making prowess, debt offering capabilities, and overall reputation. The measure allows us to incorporate trade-offs that investment banks may use in competing for new or established clients. We find that firms who switch to similar-quality underwriters enjoy more intense competition among investment banks which manifests in lower fees and more optimistic recommendations. Investment banks do compete vigorously for some clients, with the level of competition related to the likelihood of gaining or losing clients. Finally, investment banks not performing up to market norms are more likely to be dropped in the follow-on offering. In contrast, firms who seek a higher reputation underwriter face relatively non-competitive markets.

On the example of "Agrofirm Brusilov" depth analysis of the agricultural enterprises to evaluate of profitability, liquidity, solvency, financial stability, the timing of the return of invested funds and minimizing investment risks was conducted. To study methods of rating and system analysis were used. To justify the conditions of  increasing investment attractiveness farms method of scoring was used. It was established as a result of the use of integrated evaluation of the financial position one can see problem aspects of financial position of the company and develop measures to enhance liquidity, solvency, identify potential for raising the efficiency of company and prevention of financial crisis. The analysis of financial position showed that the management of the enterprise doesn’t  think  about  financial stability and solvency, does not understand the benefit of borrowed capital. Using research results in practice of agricultural enterprises allows us to give a real evaluation of investment attractiveness and justify ways to improve it. Key words: investments, investment attractiveness, potential business, financial position.

  11. Energy investments and employment

    International Nuclear Information System (INIS)

    1993-08-01

    A study was conducted to assess the effect that different energy options would have on provincial and regional employment prospects in British Columbia. Current and future economic and employment patterns were examined to develop a more detailed understanding of the skills, age, gender, location, and other characteristics of British Columbia workers. Over 40 previous studies examining the energy/employment relationship were also reviewed. Based on this review and an analysis of the province's economic and labor conditions, the following conclusions are drawn. Investment in non-energy sectors offers better prospects for reducing unemployment than investment in the energy sector, whether for new supply or improving efficiency. Investments in the energy sector provide fewer jobs than investments in most other sectors of the economy. Among the available electricity supply options, large hydroelectric projects tend to produce the fewest jobs per investment dollar. Smaller thermal projects such as wood residue plants produce the most jobs. If and when more energy is needed in British Columbia, the most cost-effective combination of energy supply and efficiency options will also create the most jobs. Compared to traditional energy supply options, investments in energy efficiency would create about twice as many total jobs, create jobs that better match the skills of the province's unemployed and its population distribution, and create jobs that last longer on the average. Construction-related measures such as improved insulation tend to produce more jobs per investment dollar than the substitution of more energy-efficient equipment. 69 refs., 9 tabs

    As with any technological innovation, time refines the technology, improving upon the original version of the innovative product. The initial GM crops had single traits for either herbicide tolerance or insect resistance. Current varieties have both of these traits stacked together and in many cases other abiotic and biotic traits have also been stacked. This innovation requires investment. While this is relatively straight forward, certain conditions need to exist such that investments can be facilitated. The principle requirement for investment is that regulatory frameworks render consistent and timely decisions. If the certainty of regulatory outcomes weakens, the potential for changes in investment patterns increases.   This article provides a summary background to the leading plant breeding technologies that are either currently being used to develop new crop varieties or are in the pipeline to be applied to plant breeding within the next few years. Challenges for existing regulatory systems are highlighted. Utilizing an option value approach from investment literature, an assessment of uncertainty regarding the regulatory approval for these varying techniques is undertaken. This research highlights which technology development options have the greatest degree of uncertainty and hence, which ones might be expected to see an investment decline. PMID:24499745

    We present a model of investment under uncertainty about fundamentals, using a global games approach. Goldstein & Razin (2003) show that there is an information based trade-off between foreign direct investment (FDI) and portfolio investment (PI) which rationalizes some well known stylised facts in the literature - the relative volatility and reversibility of foreign direct investment versus portfolio investment. We extend their result and show that uncertainty about fundamentals does not imp...

  1. Essays in Investment Theory

    International Nuclear Information System (INIS)

    Bobtcheff, C.

    2006-01-01

    This thesis analyzes different aspects of the investment decision. In the first chapter, we consider an economy in which different energy sources may produce electricity. The model focuses first on the optimal use of a hydroelectric dam from which water can be extracted and which is supplied with a random water flow. The presence of constraints on a minimal and on a maximal storage capacity makes electricity consumption smoothing possible only when the quantity of water available to the agent lies in a certain range that we determine. In a second stage, we introduce a second energy source with unlimited supply at some exogenous cost. The marginal propensity to produce hydroelectricity is an increasing function of the second technology cost. The availability at a low cost of the alternative source improves thus time diversification. Finally, the optimal electric park is composed of a number of dams that is increasing with the cost of the second technology. Chapter 2 studies the decision of an investor who wants to undertake an irreversible investment when he has the choice between two mutually exclusive projects that present input price and/or output price uncertainty. We prove that the investor decides not to invest in any project when each investment generates the same payoff independently of its size. Therefore, some inaction region appears in which the investor prefers not to invest whereas an immediate investment would have been optimal if no choice had been available: a 'choice value' is thus created. A key feature of this bidimensional degree of uncertainty is thus that the payoff generated by each project is not a sufficient statistic to make a rational investment. In this context, our analysis provides a new motive for waiting to invest: the benefits associated with the dominance of one project over the other. In chapter 3, we study the investment decision problem of a duo-poly with price competition on a market of finite size driven by stochastic taste

    2007-01-01

    A multi-dimensional, non-linear dynamic model in continuous time is presented for the purpose of finding the optimal combination of exploitation and capital investment in optimal renewable resource management. Non-malleability of capital is incorporated in the model through an asymmetric cost......-function of investment, and investments can be both positive and negative. Exploitation is controlled through the utilisation rate of available capital. A novel feature in this model is that there are costs associated with the available capital whether it is utilised or not. And, in contrast to most of the previous...... literature, the state variables, namely the physical capital and the biological resource, enter the objective function. Due to the nonlinearities in this model some of the results are in sharp contrast to previous literature....

    We present sharp reconstruction of multi-layer models using a spatially constrained inversion with minimum gradient support regularization. In particular, its application to airborne electromagnetic data is discussed. Airborne surveys produce extremely large datasets, traditionally inverted...... by using smoothly varying 1D models. Smoothness is a result of the regularization constraints applied to address the inversion ill-posedness. The standard Occam-type regularized multi-layer inversion produces results where boundaries between layers are smeared.

    Full Text Available Starting with the year 2009, the European Union, as well as the rest of the world, was affected by the economic and financial crisis, and one of the effects reflected in the decrease of foreign direct investment (FDI projects and also in the reduction of their host locations. Creating a healthy economic environment, that should be efficient for any form of international investment , represents the nowadays challenge of all market economies. This paper concentrates on analyzing our country’s attractiveness from the international investor’s point of view, it also focuses on the Romanian investment policy, its investment climate, as well as on identifying or valuating the strengths and opportunities offered by Romania. The advantages of the foreign direct investments are universally recognized and they basically include the expansion of the production capacity and income, job creation, technologically diffusion and economic development. Creating an appropriate economic environment, that is efficient for any form of international investments represents the nowadays challenge of all market economies. OECD member states experience, for example, outlines the advantages of a functional legal and normative climate, based on the principles of transparency and non discrimination, that are essential for attracting foreign investments. In the actual competition for attracting FDI, every state tries to offer as many incentives to the future foreign investors. The Romanian investment policy sets out incentives in a non-discriminatory and transparent way offering the investors the specific criteria. The Romanian business environment has improved significantly in recent years, driven in particular by EU accession. Major progress has been recorded in areas such as the fiscal environment, rule of law, the fight against corruption and property registration. When considering our country a possible location for the development of their businesses, the foreign

    2003-06-01

    Full Text Available A risk analysis for the installation of milk cooling tanks (250, 500 and 1,000 L on Brazilian rural properties was conducted in this study. The results showed that all investments had a return higher than the annual 12% minimum rate of attractiveness. There was a direct relationship between tank size and investment profitability and an inverse relation between size and risk. The probability of achieving returns lower than the opportunity cost was highest for the smallest tank (42%. In order to make the investment in small cooling tanks more attractive, the dairy industry incentives offered to farmers for supplying cooled milk could be increased. However, this approach might make investments in bulk milk collection by dairy companies infeasible. Thus, a recommendable strategy for a successful modernization of the Brazilian dairy sector’s inbound logistics would be to promote an increase in the volume of the milk produced per farm.

  16. Inflation Protected Investment Strategies

    Directory of Open Access Journals (Sweden)

    Mirco Mahlstedt

    2016-03-01

    Full Text Available In this paper, a dynamic inflation-protected investment strategy is presented, which is based on traditional asset classes and Markov-switching models. Different stock market, as well as inflation regimes are identified, and within those regimes, the inflation hedging potential of stocks, bonds, real estate, commodities and gold are investigated. Within each regime, we determine optimal investment portfolios driven by the investment idea of protection from losses due to changing inflation if inflation is rising or high, but decoupling the performance from inflation if inflation is low. The results clearly indicate that these asset classes behave differently in different stock market and inflation regimes. Whereas in the long-run, we agree with the general opinion in the literature that stocks and bonds are a suitable hedge against inflation, we observe for short time horizons that the hedging potential of each asset class, especially of real estate and commodities, depend strongly on the state of the current market environment. Thus, our approach provides a possible explanation for different statements in the literature regarding the inflation hedging properties of these asset classes. A dynamic inflation-protected investment strategy is developed, which combines inflation protection and upside potential. This strategy outperforms standard buy-and-hold strategies, as well as the well-known 1 N -portfolio.

This measures how well (or how bad) the asset performs over that given period of time. It has been established that the distribution of returns exhibits ``fat tails'' indicating that large returns occur more frequently than what is expected from standard Gaussian stochastic processes [1-3]. Instead of estimating this ``fat tail'' distribution of returns, we propose here an alternative approach, which is outlined by addressing the following question: What is the smallest time interval needed for an asset to cross a fixed return level of say 10%? For a particular asset, we refer to this time as the investment horizon and the corresponding distribution as the investment horizon distribution. This latter distribution complements that of returns and provides new and possibly crucial information for portfolio design and risk-management, as well as for pricing of more exotic options. By considering historical financial data, exemplified by the Dow Jones Industrial Average, we obtain a novel set of probability distributions for the investment horizons which can be used to estimate the optimal investment horizon for a stock or a future contract.

    Full Text Available The article studies investment strategy and efficiency of investment activity of European insurance companies. In particular, it analyses the share of investments of insurance companies of Europe in GDP, investment portfolio of European insurers and its structure, contribution of insurance companies – leaders of investment activity – into the European investment portfolio. It studies influence of the financial crisis upon investment strategy of European insurers and analyses efficiency of investment activity of European insurers in risk insurance and life insurance. The article proves that investment business models of insurance companies are capable of resisting crisis phenomena more efficiently than other financial institutions. It marks out that measures of insurance companies that are directed at increase of profitability of investments require from them both significant expenditures on creation of the system of investment risk management and open access to different categories of financial assets and markets, which influences the general risk level, taken upon by an insurance company. The author draws a conclusion that, taking into account recent developments, European insurers should focus on equity and investment risk management, finding new possibilities for their (investments growth and also adaptation of new systems and operations for solution of these important tasks.

    This paper pretends to call the attention of the audience and of the readers of it on the great importance that on a national level the programs on primary energy as well as on secondary energy saving and conservation have. Even more if we take into account that in our country by constitutional decree, the public service of electric power is reserved to the nation through the Comision Federal de Electricidad (CFE) which is a decentralized organization of the federal Mexican government, therefore subjected to, among many others, the Budgeting Law, Accountancy Law and Public Expenditure Law. We who know CFE, know the great difficulty, always raising, of getting resources for infrastructure works, among which we can cite: power plants, substations, transmission lines and distribution lines. Because of this, the energy saving and conservation programs represent for the electric sector the possibility or deferring the required investments to guarantee the energy offer. On the other hand, the users of the electric public service the implementation into its operational policies energy saving and conservation programs, undoubtedly will result into economical benefits and will improve the ratio kWh/Unit of the terminated product. Finally, in a country like ours, where 66% of generated electric power by the national electric sector comes from fossil fuel power plants, the generalized implementation of saving programs will diminish the need of generating kWh, and consequently, the emission of harmful pollutants to the environment such as nitrogen and sulfur oxides, carbon dioxide and suspended particles.

    We investigate the inverse scale space flow as a decomposition method for decomposing data into generalised singular vectors. We show that the inverse scale space flow, based on convex and even and positively one-homogeneous regularisation functionals, can decompose data represented...... by the application of a forward operator to a linear combination of generalised singular vectors into its individual singular vectors. We verify that for this decomposition to hold true, two additional conditions on the singular vectors are sufficient: orthogonality in the data space and inclusion of partial sums...... of the subgradients of the singular vectors in the subdifferential of the regularisation functional at zero. We also address the converse question of when the inverse scale space flow returns a generalised singular vector given that the initial data is arbitrary (and therefore not necessarily in the range...

  12. A-optimal encoding weights for nonlinear inverse problems, with application to the Helmholtz inverse problem

    Science.gov (United States)

    Crestel, Benjamin; Alexanderian, Alen; Stadler, Georg; Ghattas, Omar

    2017-07-01

    The computational cost of solving an inverse problem governed by PDEs, using multiple experiments, increases linearly with the number of experiments. A recently proposed method to decrease this cost uses only a small number of random linear combinations of all experiments for solving the inverse problem. This approach applies to inverse problems where the PDE solution depends linearly on the right-hand side function that models the experiment. As this method is stochastic in essence, the quality of the obtained reconstructions can vary, in particular when only a small number of combinations are used. We develop a Bayesian formulation for the definition and computation of encoding weights that lead to a parameter reconstruction with the least uncertainty. We call these weights A-optimal encoding weights. Our framework applies to inverse problems where the governing PDE is nonlinear with respect to the inversion parameter field. We formulate the problem in infinite dimensions and follow the optimize-then-discretize approach, devoting special attention to the discretization and the choice of numerical methods in order to achieve a computational cost that is independent of the parameter discretization. We elaborate our method for a Helmholtz inverse problem, and derive the adjoint-based expressions for the gradient of the objective function of the optimization problem for finding the A-optimal encoding weights. The proposed method is potentially attractive for real-time monitoring applications, where one can invest the effort to compute optimal weights offline, to later solve an inverse problem repeatedly, over time, at a fraction of the initial cost.

  18. Chinese investment in the EU renewable energy sector: Motives, synergies and policy implications

    International Nuclear Information System (INIS)

    Curran, Louise; Lv, Ping; Spigarelli, Francesca

    2017-01-01

    This paper addresses three questions: how have trade and investment in wind and solar sectors evolved between the EU and China in recent years? Is there a link between rising trade conflicts and trade and investment trends? And what wider motivations and synergies can be identified in Chinese investments in the EU's RE sector? To address these questions we analyze trade and investment data, as well as qualitative data, including information from media and company reports. Large increases in trade and investment were followed by rapid falls since 2012–13. Trade tensions have not led to increases in investment, rather the inverse. We find that Chinese investment in these two sectors is very concentrated in Germany. The key motivation for investment is market seeking, although R+D is also important, especially for wind. Most investments are greenfield, a preference that has persisted over time. Our qualitative analysis of several key acquisitions indicates that technology integration and the consolidation of capacities across the supply chain were key motivations in most of the cases studied. We conclude with some policy orientations. - Highlights: • Chinese investments in solar and wind in Europe are concentrated in Germany. • Large increases in trade and investment were followed by rapid falls since 2012–13. • These falls seem to be related to market difficulties. • Key investment entry mode is greenfield and motivation is market seeking. • In acquisitions, technology seeking plays a key role.

As principais conclusões apontam que os EUA podem reforçar sua posição de "potência inteligente" se investirem mais em bens públicos globais, oferecendo o que povos e governos ao redor do mundo desejam, mas não conseguem sozinhos. Ao complementarem seu poder militar e econômico com um investimento maior em seu poder brando, os EUA poderiam reconstruir a estrutura necessária para lidar com desafios globais.

    This paper summarizes the content of Capgemini's 10. European Energy Markets Observatory (EEMO) report. The EEMO is an annual report that tracks the progress in establishing an open and competitive electricity and gas market in the 27 European countries, including Norway and Switzerland. This tenth edition is based on 2007 and winter 2007-2008 data sets. A 1 trillion euros infrastructure investment is required to build the plants, electrical lines and gas pipelines needed in Europe over the next 25 years. Although today's credit crunch could severely hurt the investment cycle, analysts also anticipate a difficult period for the European energy markets once the recession is over. The report said that Europe has yet to solve the related issues of responding to its energy demand, while curbing its carbon dioxide (CO 2 ) emissions. In 2007, even at a slower pace than previous years, analysts said European electricity consumption still increased by 0.9% and CO 2 emissions stabilized, instead of decreasing. Despite the mild weather, the electricity security of supply deteriorated, analysts said. The Union for the Coordination of Transmission of Electricity (UCTE) real margin - which takes into account non-usable and unavailable generation capacities - dropped from 7.6% in 2006 to 5.3% in 2007. Analysts said without a significant and vigorous investment program in electricity and gas infrastructures, Europe's energy supply security will be threatened. Since the low point in 2005, utilities started to invest again, but have made energy mix choices that are not moving toward a reduction in CO 2 emissions as the majority (58%) of the planned generation capacities will be fossil-fueled. In 2007, investments in renewable capacities grew fast, wind being the industry's preference, with an addition of 8.3 gigawatt (GW) renewables in Europe. However, analysts said this type of 'non-scheduable' source is not always available during peak hours. This partially explains the security

  4. Bayesian seismic AVO inversion

    Energy Technology Data Exchange (ETDEWEB)

    Buland, Arild

    2002-07-01

    A new linearized AVO inversion technique is developed in a Bayesian framework. The objective is to obtain posterior distributions for P-wave velocity, S-wave velocity and density. Distributions for other elastic parameters can also be assessed, for example acoustic impedance, shear impedance and P-wave to S-wave velocity ratio. The inversion algorithm is based on the convolutional model and a linearized weak contrast approximation of the Zoeppritz equation. The solution is represented by a Gaussian posterior distribution with explicit expressions for the posterior expectation and covariance, hence exact prediction intervals for the inverted parameters can be computed under the specified model. The explicit analytical form of the posterior distribution provides a computationally fast inversion method. Tests on synthetic data show that all inverted parameters were almost perfectly retrieved when the noise approached zero. With realistic noise levels, acoustic impedance was the best determined parameter, while the inversion provided practically no information about the density. The inversion algorithm has also been tested on a real 3-D dataset from the Sleipner Field. The results show good agreement with well logs but the uncertainty is high. The stochastic model includes uncertainties of both the elastic parameters, the wavelet and the seismic and well log data. The posterior distribution is explored by Markov chain Monte Carlo simulation using the Gibbs sampler algorithm. The inversion algorithm has been tested on a seismic line from the Heidrun Field with two wells located on the line. The uncertainty of the estimated wavelet is low. In the Heidrun examples the effect of including uncertainty of the wavelet and the noise level was marginal with respect to the AVO inversion results. We have developed a 3-D linearized AVO inversion method with spatially coupled model parameters where the objective is to obtain posterior distributions for P-wave velocity, S

    The seismic reflection exploration technique which is one of the geophysical methods for oil exploration became effectively to image the subsurface structure with rapid development of computer. However, the imagining of subsurface based on the conventional data processing is almost impossible to obtain the information on physical properties of the subsurface such as velocity and density. Since seismic data are implicitly function of velocities of subsurface, it is necessary to develop the inversion method that can delineate the velocity structure using seismic topography and waveform inversion. As a tool to perform seismic inversion, seismic forward modeling program using ray tracing should be developed. In this study, we have developed the algorithm that calculate the travel time of the complex geologic structure using shooting ray tracing by subdividing the geologic model into blocky structure having the constant velocity. With the travel time calculation, the partial derivatives of travel time can be calculated efficiently without difficulties. Since the current ray tracing technique has a limitation to calculate the travel times for extremely complex geologic model, our aim in the future is to develop the powerful ray tracer using the finite element technique. After applying the pseudo waveform inversion to the seismic data of Korea offshore, we can obtain the subsurface velocity model and use the result in bring up the quality of the seismic data processing. If conventional seismic data processing and seismic interpretation are linked with this inversion technique, the high quality of seismic data processing can be expected to image the structure of the subsurface. Future research area is to develop the powerful ray tracer of ray tracing which can calculate the travel times for the extremely complex geologic model. (author). 39 refs., 32 figs., 2 tabs.

    The inverse data space provides a natural separation of primaries and surface-related multiples, as the surface multiples map onto the area around the origin while the primaries map elsewhere. However, the calculation of the inverse data is far from trivial as theory requires infinite time and offset recording. Furthermore regularization issues arise during inversion. We perform the inversion by minimizing the least-squares norm of the misfit function by constraining the $ell_1$ norm of the solution, being the inverse data space. In this way a sparse inversion approach is obtained. We show results on field data with an application to surface multiple removal.

    Population investment is a major topic in the studies of population and economic relations. In this particular area, numerous theoretical and practical problems are still in need of solution. Concerning the problem of population concept, there are three different approaches: (1) to determine the definition of population investment from the relationship between the population growth and the capital from national income used for investment, including investment in the newly increased population and investment in the entire population; (2) to explain population investment from the economic viewpoint that people are producers; and (3) to explain population investment from the expense needed to change a simple labor force to a skillful labor force. The expenses include educational costs, maintanance spending, wages needed to compensate workers in labor, costs for workers to master and learn modern scientific techniques to be used for production, and the costs of keeping a young labor force in the next generation.

    Full Text Available Investment professionals, particularly financial analysts or security analysts evaluate securities and try to determine characteristics of securities and to identify mispriced securities. For that purpose they use different models to estimate the intrinsic value of the common stocks. Traditional valuation models based on the present value of future cash flows are affected by estimated growth rate of the variable used and by the investor’s required rate of return. These models can be used for valuing fixed income securities, such as bonds and preferred stocks. However, in valuing companies with significant growth opportunities they have to expand traditional analysis with option valuation.

    2007-01-01

    It is shown that emulsions stabilized by ionic surfactants can be inverted by controlling the electrical potential across the oil-water interface. The potential dependent partitioning of sodium dodecyl sulfate (SDS) was studied by cyclic voltammetry at the 1,2-dichlorobenzene|water interface. In the emulsion the potential control was achieved by using a potential-determining salt. The inversion of a 1,2-dichlorobenzene-in-water (O/W) emulsion stabilized by SDS was followed by conductometry as a function of added tetrapropylammonium chloride. A sudden drop in conductivity was observed, indicating the change of the continuous phase from water to 1,2-dichlorobenzene, i.e. a water-in-1,2-dichlorobenzene emulsion was formed. The inversion potential is well in accordance with that predicted by the hydrophilic-lipophilic deviation if the interfacial potential is appropriately accounted for

    Full Text Available This study is a multivariate analysis of commodities and stock investment in a newly established market scenario. Return distribution asymmetry is examined with higher order movements. Skewness in commodity future’s return is largely insignificant, whereas kurtosis is highly significant for both stock and commodity future contracts. Correlation analysis is done with Pearson’s and Kendall’s tau measures. Commodities provide significant diversification benefits when added in a portfolio of stocks. Compared with stocks, commodity future’s returns show stronger correlation with unexpected inflation. The volatility is measured through Glosten-Jagannathan-Runkle - Generalized Autoregressive Conditional Heteroskedasticity (GJR-GARCH model and reflects that commodities have inverted asymmetric behavior, that is, more impact from the upward shocks compared with downward. Stocks have asymmetric volatility, that is, more impact from negative shocks compared with positive. Gold has highest inverted asymmetric volatility. Tail dependence, measured through Student’s t copula, shows no combined downside movement. In conclusion, commodity investments provide diversification and inflation protection.

    The authors reflect on the article in this issue entitled "Borrow or Serve? An Economic Analysis of Options for Financing a Medical School Education" by Marcu and colleagues, which makes a compelling case that a medical school education is a good investment, no matter what financing option students use, from federal service programs to federal loans. The lead author of this Commentary shares lessons learned from his own medical school education, which was funded by an Armed Forces Health Professions Scholarship, and from his current position interacting with medical students across the United States.Regardless of the financing path they choose, all students should understand basic financial concepts and the details of the various pathways that are available to pay for their medical school education, as well as how each could potentially impact their own future and that of their families. One underappreciated aspect of financing a medical school education is that federal repayment scenarios can link loan payments to income, rather than debt levels, which means that all physicians are able to afford their loan payments no matter what specialty they practice, what they are paid, or where they live.Medical education, while expensive, remains the good investment. An MD degree can lead to a lifetime of personal fulfillment and societal contributions. Everyone, with rare exceptions, accepted to a U.S. medical school will be able to finance their medical education via a path that aligns with their personal values and priorities.

    Techniques from computational algebra provide a framework for treating large classes of inverse problems. In particular, the discretization of many types of integral equations and of partial differential equations with undetermined coefficients lead to systems of polynomial equations. The structure of the solution set of such equations may be examined using algebraic techniques.. For example, the existence and dimensionality of the solution set may be determined. Furthermore, it is possible to bound the total number of solutions. The approach is illustrated by a numerical application to the inverse problem associated with the Helmholtz equation. The algebraic methods are used in the inversion of a set of transverse electric (TE) mode magnetotelluric data from Antarctica. The existence of solutions is demonstrated and the number of solutions is found to be finite, bounded from above at 50. The best fitting structure is dominantly one dimensional with a low crustal resistivity of about 2 ohm-m. Such a low value is compatible with studies suggesting lower surface wave velocities than found in typical stable cratons

Such a low value is compatible with studies suggesting lower surface wave velocities than found in typical stable cratons.

  19. Inverse transition radiation

    International Nuclear Information System (INIS)

    Steinhauer, L.C.; Romea, R.D.; Kimura, W.D.

    1997-01-01

    A new method for laser acceleration is proposed based upon the inverse process of transition radiation. The laser beam intersects an electron-beam traveling between two thin foils. The principle of this acceleration method is explored in terms of its classical and quantum bases and its inverse process. A closely related concept based on the inverse of diffraction radiation is also presented: this concept has the significant advantage that apertures are used to allow free passage of the electron beam. These concepts can produce net acceleration because they do not satisfy the conditions in which the Lawson-Woodward theorem applies (no net acceleration in an unbounded vacuum). Finally, practical aspects such as damage limits at optics are employed to find an optimized set of parameters. For reasonable assumptions an acceleration gradient of 200 MeV/m requiring a laser power of less than 1 GW is projected. An interesting approach to multi-staging the acceleration sections is also presented. copyright 1997 American Institute of Physics

  20. Multilateral negotiations in foreign investment

    2016-04-01

    Full Text Available Direct foreign investment is one of the most important economic variables in the world. Aspects related to international investment agreements are reaching an outstanding place in economic international diplomacy. Nowadays, in the multilateral level there is not an agreement regarding investment and therefore this study is focused on this particular type of agreement. In order to reach this objective this study shows, first of all, how different attempts have been developed to get a multicultural a agreement regarding investment, and to refuse the general opinion that says that exponential growth of foreign investment flows in recent years has given impulse to launch a multilateral investment agreement. Secondly, this study discusses about regulations related to foreign investment under current WTO regulations, such as investment, measure agreements, and service agreement. Then, it analyzes what has happened inside the WTO from the creation of the investment team at the Singapore Conference to the failed Conference in Cancun. Finally, it analyzes the main arguments against the multilateral agreement and the effects of future possible multilateral negotiations in investment and it ends with some recommendations and conclusions.

    In Keynes' General Theory, investment determines effective demand, which determines unemployment and the labour market plays a negligible role. In New Keynesian models, labour market institutions determine the natural rate of unemployment and the speed at which unemployment adjusts to it. Investment is mostly ignored as a key variable behind the problem of high unemployment, despite a strong empirical association between investment and unemployment. We discuss the evolution of the 'Keynesian'...

    This article develops a model where ownership improves efficiency of the housing market as it enhances the utility of housing consumption for some consumers. The model is based on an extended Hotelling-Lancaster utility approach in which the ideal variant of housing is obtainable only by adapting...... the home through a supplementary investment. Ownership offers low costs of adaptation, but has high contract costs compared with renting. Consumers simultaneously decide housing demand and tenure, and because of the different cost structure only consumers with strong preferences for individual adaptation...... of the home choose ownership. This article analyses the consumer's optimization. The model provides an explanation for the observation that homeowners typically live in larger dwelling units than tenants. It also provides and explanation for a high price on housing services tending to reduce homeownership...

  9. Green investment: Trends and determinants

    International Nuclear Information System (INIS)

    Eyraud, Luc; Clements, Benedict; Wane, Abdoul

    2013-01-01

    This paper fills a gap in the macroeconomic literature on renewable sources of energy. It offers a definition of green investment and analyzes the trends and determinants of this investment over the last decade for 35 advanced and emerging countries. We use a new multi-country historical dataset and find that green investment has become a key driver of the energy sector and that its rapid growth is now mostly driven by China. Our econometric results suggest that green investment is boosted by economic growth, a sound financial system conducive to low interest rates, and high fuel prices. We also find that some policy interventions, such as the introduction of carbon pricing schemes or “feed-in-tariffs,” which require use of “green” energy, have a positive and significant impact on green investment. Other interventions, such as biofuel support, do not appear to be associated with higher green investment. - Highlights: • We offer a definition of green investment and review its trend since 2000. • We analyze its determinants from both theoretical and empirical perspectives. • Green investment is boosted by economic growth, interest rates, and fuel prices. • Feed-in-tariffs and carbon pricing schemes impact positively green investment

  13. Investment in Green Technologies

    Science.gov (United States)

    Das Gupta, Supratim

    Since the middle of the 1970's, there has been considerable research about how to deal with exhaustible natural resources which are essential to production. In the absence of substitution possibilities, the finite stock of these resources acts as a limiting factor to continued growth of output and hence consumption possibilities. In our first chapter, we combine a finite natural resource and human capital in the production function and look at the possibility of maintaining a non-declining or sustainable level of consumption for an infinite horizon. Our results show that the return to human capital accumulation plays a key role in ensuring this objective. In our model without physical capital, we obtain a similar result where this return must be such that the fraction of time devoted to acquiring human capital each period is at least as much as the share of natural resources in output. Our second chapter focuses on the transition from a relatively cheap exhaustible natural resource (coal, gasoline) to an expensive alternative technology assumed to be in nearly unlimited supply (wind, solar). Due to significant cost differences between fossil-fuel based energy sources and these alternative (backstop) technologies, their use is not as widespread. Public subsidies to research can however bring about innovation through cheaper production techniques which would significantly reduce the operating costs of these backstop technologies. But without sufficient incentives for investment and patent protections, individual firms typically underinvest in backstop technologies relative to the socially optimal level. In our paper, we find that this underinvestment in the backstop also leads to an under-extraction of the exhaustible natural resource. This imply firms would conserve the natural resource for too long and switch later to the alternative technology relative to the socially optimal solution. We extend the chapter to include pollution as a flow variable. Pollution from

  1. Alternative approaches to transmission investment

    International Nuclear Information System (INIS)

    Welch, J.L.

    2004-01-01

    The International Transmission Company (ITC) is an independent power transmission company that owns, operates and maintains the high voltage transmission system in southeastern Michigan. The company's current focus is on investing in the transmission infrastructure to improve reliability, relieve congestion, improve access to generation and reduce energy costs for consumers. There is a need for investment in power transmission. Trends indicate that power transactions are on the rise while transmission investment is lagging because pricing protocols are inadequate and there is no regional tariff mechanism to allocate the benefits of new investment. The presentation reviewed the applicability of FTRs to transmission owners and the pitfalls of participant funding pricing. It also outlined the regional benefit allocation mechanism (RBAM) with an illustrative example. It was concluded that existing pricing policies must be improved to address the growing need for transmission investment. RBAM is needed to help investors recover costs from project beneficiaries. figs

  3. Public investment versus private investment: The case of Zambia

    Directory of Open Access Journals (Sweden)

    Garikai Makuyana

    2014-05-01

    Full Text Available This paper highlights the growth dynamics of public and private investment in Zambia from 1964 to 2011. The evolution of the two components of investment in Zambia has been a product of market intervention and market-based policies. Initially, after its independence in 1964, the perpetuated market economy limited public investment growth to the basic infrastructural provision – for the first three years. However, the 1967 Mulungushi and the 1968 Matero nationalisation programmes brought about rapid expansion in public investment, especially from the early 1970s to the late 1980s. The market-based reforms that have been implemented in Zambia from 1991 have promoted private investment leadership – thereby, allowing public investment growth in economic activities that have complemented the private sector growth. Although private investment has grown to a position of economic dominance in Zambia, like many developing countries, the country still faces some challenges. These include inadequate and poor infrastructure, the high cost of human capital, cumbersome administrative procedures, and the high cost of financial capital.

  4. Chinese investments in the EU

    Full Text Available China’s investments in the European Union are much lower than what you may expect given the economic size of both entities. These relatively low investments in Europe are a combination of priority and obstacles. The priority for investments is clearly in Asia, Africa and Latin America. This regional pattern is heavily influenced by the need to solve the resource shortage in the medium and long term. The investments in Europe and the United States are mostly market seeking investments. Research specifically focused on Chinese M&A abroad comes to the same conclusion. The success rate of Chinese M&A abroad is much lower than what we see with respect to American or European investments abroad. In this paper, we examine why Chinese firms are facing more difficulties in the European Union than in other regions. The paper focuses on Chinese M&A as proxy for total foreign direct investments abroad. By looking at the factors that have been documented as influencing the level of M&A abroad, it becomes clear that Chinese firms in Europe are hindered by many factors. For example, the trade between China and the EU is relatively low, the institutional quality is lower compared to the United States, there is less experience with respect to Europe and relatively many deals relate to State Owned Enterprises (SOE which makes the deal sensitive. So it is logical that Chinese investments are not very high in Europe. However, the research makes clear that the obstacles for Chinese investments in Europe are disappearing step by step. In that sense, we expect a strong increase of Chinese investments in Europe in the future.

  6. Considering barriers to investment in South Africa

    KB Afful

    2014-10-01

    Full Text Available This paper examines the effect of South Africa’s economic fundamentals on net direct investment and net portfolio investment. The results suggest that the main determinants of investment in South Africa are resource prices, input productivity and the economic performance of the domestic economy. The results illustrate that net direct investment and net portfolio investment are close but not perfect substitutes. In addition, we find that an increase in labour input costs reduces both net direct investment and net portfolio investment. Further, an increase in fixed capital productivity increases net direct investment. Further, also the results illustrate that subsidies increase both net direct investment and net portfolio investment. Moreover, an increase in exports increases both net direct investment and net portfolio investment. Policy recommendations are thus proposed that may increase foreign direct investment in South Africa.

It was claimed that the quality point of view should be demanding part of investments in logistics. Val Log was proposed as an answer to the issues of managing quality of investments in logistics at the tactical level in organizations. By Val Log it is possible to overcome the myth that logistics projects cost money while business projects bring money. Val Log also provides detailed instructions for goals and metrics for each process. By doing changes the quality should be the obvious pillar of our affords doing it.

In the case of constant risk aversion it turns out that the optimal amount of money to invest in stocks is independent of wealth...... of future labor income net of consumption. Using the verification theorem we give a detailed analysis of this problem. It turns out that the optimal amount of money to invest in stocks is given by a linear function of wealth plus the financial value of future labor income net of consumption. The optimal...... consumption strategy is again given as a deterministic bang-bang strategy.

    The state of the groundwater inverse problem is synthesized. Emphasis is placed on aquifer characterization, where modelers have to deal with conceptual model uncertainty (notably spatial and temporal variability), scale dependence, many types of unknown parameters (transmissivity, recharge, boundary conditions, etc.), nonlinearity, and often low sensitivity of state variables (typically heads and concentrations) to aquifer properties. Because of these difficulties, calibration cannot be separated from the modeling process, as it is sometimes done in other fields. Instead, it should be viewed as one step in the process of understanding aquifer behavior. In fact, it is shown that actual parameter estimation methods do not differ from each other in the essence, though they may differ in the computational details. It is argued that there is ample room for improvement in groundwater inversion: development of user-friendly codes, accommodation of variability through geostatistics, incorporation of geological information and different types of data (temperature, occurrence and concentration of isotopes, age, etc.), proper accounting of uncertainty, etc. Despite this, even with existing codes, automatic calibration facilitates enormously the task of modeling. Therefore, it is contended that its use should become standard practice. L'état du problème inverse des eaux souterraines est synthétisé. L'accent est placé sur la caractérisation de l'aquifère, où les modélisateurs doivent jouer avec l'incertitude des modèles conceptuels (notamment la variabilité spatiale et temporelle), les facteurs d'échelle, plusieurs inconnues sur différents paramètres (transmissivité, recharge, conditions aux limites, etc.), la non linéarité, et souvent la sensibilité de plusieurs variables d'état (charges hydrauliques, concentrations) des propriétés de l'aquifère. A cause de ces difficultés, le calibrage ne peut êtreséparé du processus de modélisation, comme c'est le

    Assessing facial attractiveness is a ubiquitous, inherent, and hard-wired phenomenon in everyday interactions. As such, it has highly adapted to the default way that faces are typically processed: viewing faces in upright orientation. By inverting faces, we can disrupt this default mode, and study how facial attractiveness is assessed. Faces, rotated at 90 (tilting to either side) and 180°, were rated on attractiveness and distinctiveness scales. For both orientations, we found that faces were rated more attractive and less distinctive than upright faces. Importantly, these effects were more pronounced for faces rated low in upright orientation, and smaller for highly attractive faces. In other words, the less attractive a face was, the more it gained in attractiveness by inversion or rotation. Based on these findings, we argue that facial attractiveness assessments might not rely on the presence of attractive facial characteristics, but on the absence of distinctive, unattractive characteristics. These unattractive characteristics are potentially weighed against an individual, attractive prototype in assessing facial attractiveness. Copyright © 2017 The Authors. Published by Elsevier B.V.

  4. Multiples waveform inversion

    KAUST Repository

    Zhang, Dongliang

    2013-01-01

    To increase the illumination of the subsurface and to eliminate the dependency of FWI on the source wavelet, we propose multiples waveform inversion (MWI) that transforms each hydrophone into a virtual point source with a time history equal to that of the recorded data. These virtual sources are used to numerically generate downgoing wavefields that are correlated with the backprojected surface-related multiples to give the migration image. Since the recorded data are treated as the virtual sources, knowledge of the source wavelet is not required, and the subsurface illumination is greatly enhanced because the entire free surface acts as an extended source compared to the radiation pattern of a traditional point source. Numerical tests on the Marmousi2 model show that the convergence rate and the spatial resolution of MWI is, respectively, faster and more accurate then FWI. The potential pitfall with this method is that the multiples undergo more than one roundtrip to the surface, which increases attenuation and reduces spatial resolution. This can lead to less resolved tomograms compared to conventional FWI. The possible solution is to combine both FWI and MWI in inverting for the subsurface velocity distribution.

  9. Investment in new product reliability

    International Nuclear Information System (INIS)

    2009-01-01

    Product reliability is of great importance to both manufacturers and customers. Building reliability into a new product is costly, but the consequences of inadequate product reliability can be costlier. This implies that manufacturers need to decide on the optimal investment in new product reliability by achieving a suitable trade-off between the two costs. This paper develops a framework and proposes an approach to help manufacturers decide on the investment in new product reliability.

  1. Investments in liberalised power markets

    International Nuclear Information System (INIS)

    Grenaa Jensen, S.; Meibom, P.

    2005-01-01

    There is considerable uncertainty in the Nordic electricity system with respect to the long-term development in production capacity. The process towards liberalisation of the electricity sector started with a situation of a large capacity margin, but this margin is gradually vanishing. Since the potential investors in new production capacity are unaccustomed with investments under the new regime, it is unknown if and when investments will take place. The purpose of the present study is to analyze if and when investors choose to invest in new electricity production capacity depending on their existing portfolio of power producing units. Electricity price scenarios generated with a partial equilibrium model (Balmorel) are combined with a model of investment decisions. In this, various scenarios concerning the development in the Nordic power market, such as new transmission lines between neighbouring countries, more installed wind power, and changes in CO 2 emission trading costs, are used to investigate the consequences for investments in a natural gas fired, combined cycle power plant. The main result of the analysis is that new investments are highly sensitive to investors existing power production portfolio, as new production units affect the merit order in the power market, i.e. compete with the existing power plants.

    2017-01-01

    This book addresses selected topics in the theory of generalized inverses. Following a discussion of the “reverse order law” problem and certain problems involving completions of operator matrices, it subsequently presents a specific approach to solving the problem of the reverse order law for {1} -generalized inverses. Particular emphasis is placed on the existence of Drazin invertible completions of an upper triangular operator matrix; on the invertibility and different types of generalized invertibility of a linear combination of operators on Hilbert spaces and Banach algebra elements; on the problem of finding representations of the Drazin inverse of a 2x2 block matrix; and on selected additive results and algebraic properties for the Drazin inverse. In addition to the clarity of its content, the book discusses the relevant open problems for each topic discussed. Comments on the latest references on generalized inverses are also included. Accordingly, the book will be useful for graduate students, Ph...

Then, we study the inverse problem of retrieving the optical parameters from boundary measurements, with help of existing results by Choulli and Stefanov. This theoretical analysis is the framework of an attempt to model the color of the skin. For this purpose, a code has been developed to solve the RTE and to study the sensitivity of the measurements made by biophysicists with respect to the physiological parameters responsible for the optical properties of this complex, multi-layered material. On étudie l’équation du transfert radiatif (ETR dans un domaine tridimensionnel infini dans deux directions, et on prouve un résultat d’existence.

Cette analyse sert de cadre théorique à un travail de modélisation de la couleur de la peau. Dans cette perspective, un code à été développé pour résoudre l’ETR et étudier la sensibilité des mesures effectuées par les biophysiciens par rapport aux paramètres physiologiques tenus pour responsables des propriétés optiques de ce complexe matériau multicouche.

    Security of the systems is normally interdependent in such a way that security risks of one part affect other parts and threats spread through the vulnerable links in the network. So, the risks of the systems can be mitigated through investments in the security of interconnecting links. This article takes an innovative look at the problem of security investment of nodes on their vulnerable links in a given contagious network as a game-theoretic model that can be applied to a variety of applications including information systems. In the proposed game model, each node computes its corresponding risk based on the value of its assets, vulnerabilities, and threats to determine the optimum level of security investments on its external links respecting its limited budget. Furthermore, direct and indirect nonlinear influences of a node's security investment on the risks of other nodes are considered. The existence and uniqueness of the game's Nash equilibrium in the proposed game are also proved. Further analysis of the model in a practical case revealed that taking advantage of the investment effects of other players, perfectly rational players (i.e., those who use the utility function of the proposed game model) make more cost-effective decisions than selfish nonrational or semirational players. © 2018 Society for Risk Analysis.

    As liberalisation of global trade and investment accelerates, what happens to the environment? As the world heads for confrontation in Seattle, the questions intensify. Does foreign direct investment mean forsaking environmental protection? Or do multinational corporations export higher standards when they invest abroad? Can a powerful trading nation ban imports of tropical timber produced unsustainably? Should the World Trade Organisation take the views of industry or environmental groups into account when deciding? Must world trade rules be changed to accommodate environmental concerns? This book analyzes key issues in this increasingly controversial arena and includes contributions from Renato Ruggiero, former Director General of the World Trade Organization; The Rt Hon Brian Wilson MP, former UK Minister of Trade; Dr Magda Shahin, Deputy Assistant Minister of Foreign Affairs at the Egyptian Ministry of Foreign Affairs; Pradeep Mehta, Secretary General, Consumer Unity and Trust Society, India; and Dr Michel Potier, Head of the Economics Division at the OECD's Environment Directorate.

    Full Text Available Foreign Direct Investments are a very important segment in the economic activity of a country, due to the effects they bring with. This is mainly because of the trade liberalization, as well as other advantages such as higher returns on investments, potential resource seeking, new market seeking, or cheap labor force. The issue of Foreign Direct Investment is very broad, but in concrete terms, the main goal of this article is the theoretical analysis and its impact in related policies in Albania. Another objective is closely connected with the help of government authorities to better understand the potential and effective impact of FDI in the Albanian economy and use this information in their decision-making.

  9. Bayesian Approach to Inverse Problems

    CERN Document Server

    2008-01-01

    Many scientific, medical or engineering problems raise the issue of recovering some physical quantities from indirect measurements; for instance, detecting or quantifying flaws or cracks within a material from acoustic or electromagnetic measurements at its surface is an essential problem of non-destructive evaluation. The concept of inverse problems precisely originates from the idea of inverting the laws of physics to recover a quantity of interest from measurable data.Unfortunately, most inverse problems are ill-posed, which means that precise and stable solutions are not easy to devise. Regularization is the key concept to solve inverse problems.The goal of this book is to deal with inverse problems and regularized solutions using the Bayesian statistical tools, with a particular view to signal and image estimation

  10. Testing earthquake source inversion methodologies

    KAUST Repository

    Page, Morgan T.

    2011-01-01

    Source Inversion Validation Workshop; Palm Springs, California, 11-12 September 2010; Nowadays earthquake source inversions are routinely performed after large earthquakes and represent a key connection between recorded seismic and geodetic data and the complex rupture process at depth. The resulting earthquake source models quantify the spatiotemporal evolution of ruptures. They are also used to provide a rapid assessment of the severity of an earthquake and to estimate losses. However, because of uncertainties in the data, assumed fault geometry and velocity structure, and chosen rupture parameterization, it is not clear which features of these source models are robust. Improved understanding of the uncertainty and reliability of earthquake source inversions will allow the scientific community to use the robust features of kinematic inversions to more thoroughly investigate the complexity of the rupture process and to better constrain other earthquakerelated computations, such as ground motion simulations and static stress change calculations.

Thus inverse problems are recasted in a form suitable for statistical inference. In particular, a Bayesian approach for regularisation...... problem is given in terms of probability distributions. Posterior inference is obtained by Markov chain Monte Carlo methods and new, powerful simulation techniques based on e.g. coupled Markov chains and simulated tempering is developed to improve the computational efficiency of the overall simulation......Inverse problems arise in many scientific disciplines and pertain to situations where inference is to be made about a particular phenomenon from indirect measurements. A typical example, arising in diffusion tomography, is the inverse boundary value problem for non-invasive reconstruction...

Real options influence investment behavior when risky investments in human capital are irreversible and individuals can affect the timing of the investment. Option values make individuals more reluctant to invest in human capital and, as a result, required returns on the investment increase. Real options may help to explain a larger human capital premium for higher education, smaller responsiveness of higher education inve...

    Inverse cascades of magnetic quantities for turbulent incompressible magnetohydrodynamics are reviewed, for two and three dimensions. The theory is extended to the Strauss equations, a description intermediate between two and three dimensions appropriate to tokamak magnetofluids. Consideration of the absolute equilibrium Gibbs ensemble for the system leads to a prediction of an inverse cascade of magnetic helicity, which may manifest itself as a major disruption. An agenda for computational investigation of this conjecture is proposed

  20. An analysis of household farm investment decisions under varying land tenure arrangements in Ghana

    Directory of Open Access Journals (Sweden)

    Michael Ayamga

    2016-01-01

    Full Text Available Land tenure insecurity is widely perceived as a disincentive for long-term land improvement investment hence the objective of this paper is to evaluate how tenure (insecurity associated with different land use arrangements in Ghana influenced households’ plot level investment decisions and choices. The paper uses data from the Farmer-Based Organisations (FBO survey. The FBO survey collected information from 2,928 households across three ecological zones of Ghana using multistaged cluster sampling. Probit and Tobit models tested the effects of land tenancy and ownership arrangements on households’ investment behaviour while controlling other factors. It was found that marginal farm size was inversely related to tenure insecurity while tenure insecurity correlate positively with value of farm land and not farm size. Individual ownership and documentation of land significantly reduced the probability of households losing uncultivated lands. Individual land ownership increased both the probability of investing and level of investments made in land improvement and irrigation probably due to increasing importance households place on land ownership. Two possible explanations for this finding are: First, that land markets and land relations have changed significantly over the last two decades with increasing money transaction and fixed agreements propelled by population growth and increasing value of land. Secondly, inclusion of irrigation investment as a long term investment in land raises the value of household investment and the time period required to reap the returns on the investments. Households take land ownership and duration of tenancy into consideration if the resource implications of land investments are relatively huge and the time dimension for harvesting returns to investments is relatively long.

    Hirth, Stefan; Uhrig-Homburg, Marliese

    2010-01-01

    This paper analyzes the investment timing of firms facing two dimensions of financing constraints: Liquidity constraints and capital market frictions inducing financing costs. We show that liquidity constraints are not sufficient to explain voluntary investment delay. However, when additionally...... considering financing costs, we can explain both voluntary delay and acceleration of investment. More precisely, we find that investment thresholds are U-shaped in liquid funds. For high-liquidity firms, investment thresholds are decreasing (i.e. accelerated investment takes place) in either dimension...... of financing constraint. In contrast, investment thresholds are increasing (i.e. investment is further delayed) in either form of financing constraint for low-liquidity firms. For intermediate levels of liquidity, investment thresholds are U-shaped in market frictions....

    In the Mexico's National Energy Balance of 2008, it is considered that of the total of the electrical power consumption in our country, 18% is dedicated to lighting. Conscious of the necessity of saving energy in public lighting in this article is presented the design, construction and analysis of the power consumption of a public light fed with electricity of photovoltaic cells and the control of intensity on the light in inverse way of the natural light. A lamp constructed based in light emitting diodes (LEDs) is used. This has the quality of consuming very little energy that could be provided by the sun and be stored to use it at night. With this system, proven at scale, energy savings are obtained superior to 50% of the conventional one and, in relation to the commercial photovoltaic (FV) luminaries up to 30%.

    International Nuclear Information System (INIS)

    Fenimore, E.E.; Klebesadel, R.W.; Laros, J.G.

    1983-01-01

    There are currently two radiation mechanisms being considered for gamma-ray bursts: thermal synchrotron and inverse comptonization. They are mutually exclusive since thermal synchrotron requires a magnetic field of approx. 10 12 Gauss whereas inverse comptonization cannot produce a monotonic spectrum if the field is larger than 10 11 and is too inefficient relative to thermal synchrotron unless the field is less than 10 9 Gauss. Neither mechanism can explain completely the observed characteristics of gamma-ray bursts. However, we conclude that thermal synchrotron is more consistent with the observations if the sources are approx. 40 kpc away whereas inverse comptonization is more consistent if they are approx. 300 pc away. Unfortunately, the source distance is still not known and, thus, the radiation mechanism is still uncertain

    2009-01-01

    Understanding the itinerant-localised bonding role of the 5f electrons in the light actinides will afford an insight into their unusual physical and chemical properties. In recent years, the combination of core and valance band electron spectroscopies with theoretic modelling have already made significant progress in this area. However, information of the unoccupied density of states is still scarce. When compared to the forward photoemission techniques, measurements of the unoccupied states suffer from significantly less sensitivity and lower resolution. In this paper, we report on our experimental apparatus, which is designed to measure the inverse photoemission spectra of the light actinides. Inverse photoemission spectra of UO 2 and UO 2.2 along with the corresponding core and valance electron spectra are presented in this paper. UO 2 has been reported previously, although through its inclusion here it allows us to compare and contrast results from our experimental apparatus to the previous Bremsstrahlung Isochromat Spectroscopy and Inverse Photoemission Spectroscopy investigations

  9. Inverse source problems in elastodynamics

    Science.gov (United States)

    Bao, Gang; Hu, Guanghui; Kian, Yavar; Yin, Tao

    2018-04-01

    We are concerned with time-dependent inverse source problems in elastodynamics. The source term is supposed to be the product of a spatial function and a temporal function with compact support. We present frequency-domain and time-domain approaches to show uniqueness in determining the spatial function from wave fields on a large sphere over a finite time interval. The stability estimate of the temporal function from the data of one receiver and the uniqueness result using partial boundary data are proved. Our arguments rely heavily on the use of the Fourier transform, which motivates inversion schemes that can be easily implemented. A Landweber iterative algorithm for recovering the spatial function and a non-iterative inversion scheme based on the uniqueness proof for recovering the temporal function are proposed. Numerical examples are demonstrated in both two and three dimensions.

    Boyadzhiev, G.; Brandmayr, E.; Pinat, T.; Panza, G.F.

    2007-06-01

    The nonlinear inversion of geophysical data in general does not yield a unique solution, but a single model, representing the investigated field, is preferred for an easy geological interpretation of the observations. The analyzed region is constituted by a number of sub-regions where the multi-valued nonlinear inversion is applied, which leads to a multi-valued solution. Therefore, combining the values of the solution in each sub-region, many acceptable models are obtained for the entire region and this complicates the geological interpretation of geophysical investigations. In this paper are presented new methodologies, capable to select one model, among all acceptable ones, that satisfies different criteria of smoothness in the explored space of solutions. In this work we focus on the non-linear inversion of surface waves dispersion curves, which gives structural models of shear-wave velocity versus depth, but the basic concepts have a general validity.

    Detection of inclusions or obstacles inside a body by boundary measurements is an inverse problems very useful in practical applications. When only finite numbers of measurements are available, we try to detect some information on the embedded object such as its size. In this talk we review some recent results on several inverse problems. The idea is to provide constructive upper and lower estimates of the area/volume of the unknown defect in terms of a quantity related to the work that can be expressed with the available boundary data.

    We study an investment model in which agents have the wrong beliefs about the dynamic properties of fundamentals. Specifically, we assume that agents underestimate the rate of mean reversion. The model exhibits the following six properties: (i) Beliefs are excessively optimistic in good times and excessively pessimistic in bad times. (ii) Asset prices are too volatile. (iii) Excess returns are negatively autocorrelated. (iv) High levels of corporate profits predict negative future excess returns. (v) Real economic activity is excessively volatile; the economy experiences amplified investment cycles. (vi) Corporate profits are positively autocorrelated in the short run and negatively autocorrelated in the medium run. The paper provides an illustrative model of animal spirits, amplified business cycles, and excess volatility. PMID:23243469

The results of the research support the idea that the balance of economic power is changing in the world economy and the countries that own a stable and solid industrial base are at an advantage. The new trends determined by the economic crisis in the field of FDI refer to the growing percentage of developing and emerging countries in the global flows of FDI.

  20. Cost Estimates and Investment Decisions

    International Nuclear Information System (INIS)

    Emhjellen, Kjetil; Emhjellen Magne; Osmundsen, Petter

    2001-08-01

    When evaluating new investment projects, oil companies traditionally use the discounted cashflow method. This method requires expected cashflows in the numerator and a risk adjusted required rate of return in the denominator in order to calculate net present value. The capital expenditure (CAPEX) of a project is one of the major cashflows used to calculate net present value. Usually the CAPEX is given by a single cost figure, with some indication of its probability distribution. In the oil industry and many other industries, it is common practice to report a CAPEX that is the estimated 50/50 (median) CAPEX instead of the estimated expected (expected value) CAPEX. In this article we demonstrate how the practice of using a 50/50 (median) CAPEX, when the cost distributions are asymmetric, causes project valuation errors and therefore may lead to wrong investment decisions with acceptance of projects that have negative net present values.

    The future for oil producers in the Gulf is discussed and the emphasis is very much on Saudi Arabia. The net source flow to developing countries is illustrated but substantial changes are expected soon due to a combination of crises in the Far East and in Russia. Foreign investment in Saudi increased dramatically in 1997 and Saudi has great potential for maximising inward flows and minimising outward flows for the benefit of the national economy. It was stressed that at present, international factors are largely negative but domestic factors are very positive and will prevail in determining investments. The paper was presented under the sub-headings of (i) oil prices, (ii) the Asian crisis, (iii) stability in the Middle East, (iv) population growth (v) private sector viability, (vi) redefining the role of the state and (vii) long-term oil revenue prospects. Saudi Arabia is expected to continue to be a major player in the petroleum business

    Hospital capital investment is important for acquiring and maintaining technology and equipment needed to provide health care. Reduction in capital investment by a hospital has negative implications for patient outcomes. Most hospitals rely on debt and internal cash flow to fund capital investment. The great recession may have made it difficult for hospitals to borrow, thus reducing their capital investment. I investigated the impact of the great recession on capital investment made by California hospitals. Modeling how hospital capital investment may have been liquidity constrained during the recession is a novel contribution to the literature. I estimated the model with California Office of Statewide Health Planning and Development data and system generalized method of moments. Findings suggest that not-for-profit and public hospitals were liquidity constrained during the recession. Comparing the changes in hospital capital investment between 2006 and 2009 showed that hospitals used cash flow to increase capital investment by $2.45 million, other things equal. PMID:28617202

    holders have the incentive to over invest. We formulate a dynamic structural model to study the interaction of initial capital structure choice, investment policy, subsequent debt issues, and debt priority rules. We find that priority rules have a substantial impact on investment timing as well......Debt priority rules, i.e., the rules determining how different classes of debt split the firm's assets after bankruptcy, influence the firm's investment decisions. Existing debt benefits from an investment either because the investment is equity financed or because new debt issued to (partly......) finance the investment has lower priority in the event of bankruptcy as is the case for the commonly used absolute priority rule (APR). This incentivizes equity holders to under invest. If debt priority rules are specified in such a way that existing debt can be exploited by issuing new debt, do equity...

    This paper examines how the relative shares of public and private health expenditures impact income inequality. We study a two period overlapping generation's growth model in which longevity is determined by both private and public health expenditure and human capital is the engine of growth. Increased investment in health, reduces mortality, raises return to education and affects income inequality. In such a framework we show that the cross-section earnings inequality is non-decreasing in the private share of health expenditure. We test this prediction empirically using a variable that proxies for the relative intensity of investments (private versus public) using vaccination data from the National Sample Survey Organization for 76 regions in India in the year 1986-87. We link this with region-specific expenditure inequality data for the period 1987-2012. Our empirical findings, though focused on a specific health investment (vaccines), suggest that an increase in the share of the privately provided health care results in higher inequality.

    Islamic finance and Sharia-compliant investing has seen substantial growth over the years. As more investors are interested in becoming fully Sharia-compliant, the question of what may they be giving up in exchange arises. This has led us to analyze the potential of Sharia-compliant investments. It is well known that having a Sharia-compliant investment portfolio could be rather restrictive as some sectors and investment instruments are forbidden such as tobacco, alcohol, gambling, pork produ...

  19. Investment Price Rigidities and Business Cycles

    OpenAIRE

    2015-01-01

    I incorporate investment price rigidity in a two-sector monetary model of business cycles. Fit to quarterly U.S. time series, the model suggests that price sluggishness in the investment sector is the single most empirically relevant friction to match the data. Sticky investment prices constitute an important propagation mechanism to understand the sources of aggregate fluctuations, the dynamic effects of technology shocks, and the properties of the relative price of investment goods.

  5. Superconductivity in Pb inverse opal

    Aliev, Ali E.; Lee, Sergey B.; Zakhidov, Anvar A.; Baughman, Ray H.

    2007-01-01

    Type-II superconducting behavior was observed in highly periodic three-dimensional lead inverse opal prepared by infiltration of melted Pb in blue (D = 160 nm), green (D = 220 nm) and red (D = 300 nm) opals and followed by the extraction of the SiO 2 spheres by chemical etching. The onset of a broad phase transition (ΔT = 0.3 K) was shifted from T c = 7.196 K for bulk Pb to T c = 7.325 K. The upper critical field H c2 (3150 Oe) measured from high-field hysteresis loops exceeds the critical field for bulk lead (803 Oe) fourfold. Two well resolved peaks observed in the hysteresis loops were ascribed to flux penetration into the cylindrical void space that can be found in inverse opal structure and into the periodic structure of Pb nanoparticles. The red inverse opal shows pronounced oscillations of magnetic moment in the mixed state at low temperatures, T 0.9T c has been observed for all of the samples studied. The magnetic field periodicity of resistivity modulation is in good agreement with the lattice parameter of the inverse opal structure. We attribute the failure to observe pronounced modulation in magneto-resistive measurement to difficulties in the precision orientation of the sample along the magnetic field

  9. Wave-equation dispersion inversion

    KAUST Repository

    Li, Jing

    2016-12-08

    We present the theory for wave-equation inversion of dispersion curves, where the misfit function is the sum of the squared differences between the wavenumbers along the predicted and observed dispersion curves. The dispersion curves are obtained from Rayleigh waves recorded by vertical-component geophones. Similar to wave-equation traveltime tomography, the complicated surface wave arrivals in traces are skeletonized as simpler data, namely the picked dispersion curves in the phase-velocity and frequency domains. Solutions to the elastic wave equation and an iterative optimization method are then used to invert these curves for 2-D or 3-D S-wave velocity models. This procedure, denoted as wave-equation dispersion inversion (WD), does not require the assumption of a layered model and is significantly less prone to the cycle-skipping problems of full waveform inversion. The synthetic and field data examples demonstrate that WD can approximately reconstruct the S-wave velocity distributions in laterally heterogeneous media if the dispersion curves can be identified and picked. The WD method is easily extended to anisotropic data and the inversion of dispersion curves associated with Love waves.

  10. Adjoint modeling for acoustic inversion

    Hursky, Paul; Porter, Michael B.; Cornuelle, B. D.; Hodgkiss, W. S.; Kuperman, W. A.

    2004-02-01

    The use of adjoint modeling for acoustic inversion is investigated. An adjoint model is derived from a linearized forward propagation model to propagate data-model misfit at the observation points back through the medium to the medium perturbations not being accounted for in the model. This adjoint model can be used to aid in inverting for these unaccounted medium perturbations. Adjoint methods are being applied to a variety of inversion problems, but have not drawn much attention from the underwater acoustic community. This paper presents an application of adjoint methods to acoustic inversion. Inversions are demonstrated in simulation for both range-independent and range-dependent sound speed profiles using the adjoint of a parabolic equation model. Sensitivity and error analyses are discussed showing how the adjoint model enables calculations to be performed in the space of observations, rather than the often much larger space of model parameters. Using an adjoint model enables directions of steepest descent in the model parameters (what we invert for) to be calculated using far fewer modeling runs than if a forward model only were used.

    Despite many theoretical advances and the increasing availability of high-performance computing clusters, full seismic waveform inversions still face considerable challenges regarding data and workflow management. While the community has access to solvers which can harness modern heterogeneous computing architectures, the computational bottleneck has fallen to these often manpower-bounded issues that need to be overcome to facilitate further progress. Modern inversions involve huge amounts of data and require a tight integration between numerical PDE solvers, data acquisition and processing systems, nonlinear optimization libraries, and job orchestration frameworks. To this end we created a set of libraries and applications revolving around Salvus (http://salvus.io), a novel software package designed to solve large-scale full waveform inverse problems. This presentation focuses on solving passive source seismic full waveform inversions from local to global scales with Salvus. We discuss (i) design choices for the aforementioned components required for full waveform modeling and inversion, (ii) their implementation in the Salvus framework, and (iii) how it is all tied together by a usable workflow system. We combine state-of-the-art algorithms ranging from high-order finite-element solutions of the wave equation to quasi-Newton optimization algorithms using trust-region methods that can handle inexact derivatives. All is steered by an automated interactive graph-based workflow framework capable of orchestrating all necessary pieces. This naturally facilitates the creation of new Earth models and hopefully sparks new scientific insights. Additionally, and even more importantly, it enhances reproducibility and reliability of the final results.

    Full Text Available E n la planificación operativa de los sistemas de transporte es fundamental contar con una caracterización de la demanda del servicio por medio de una matriz origen- destino (OD de viajes. Esta matriz es estimada frecuentemente mediante técnicas de muestreo estadístico que ofrecen resultados de gran calidad pero requieren diseño e implementación compleja y de alto costo. Así, se hace pertinente aprovechar la información de los registros de las tarjetas inteligentes usadas como medios de pago en los sistemas que tienen esta tecnología. Esta fuente de información permite obtener estimaciones de matrices OD de gran calidad con un costo bajo. En este trabajo se implementa una metodología para la estimación de una matriz origen-destino entre estaciones de buses en el sistema de transporte público de Megabús en la ciudad de Pereira. La metodología permite depurar la base de datos teniendo en cuenta las particularidades del sistema, como las formas de ingreso, tipo de tarjeta, reventa de pasajes, y además considera la posibilidad de que un usuario pueda decidir bajarse en una estación intermedia cercana a su estación destino mediante la parametrización de un factor de penalización que está asociado con el tiempo de viaje caminando en la función objetivo. La inclusión del factor no influye significativamente en el porcentaje total de viajes estimados pero sí ajusta algunos valores de la matriz origen-destino, al considerar los descensos en estaciones intermedias. El método posibilita estimar matrices OD para diferentes ventanas de tiempo de cualquier día de la semana y distintas épocas del año.

Es la alternativa a la Escuela 2.0 y la idea central es facilitar el acceso, desde cualquier lugar del centro, a las TIC como recurso de apoyo en el proceso de enseñanza y aprendizaje. En coherencia con el proyecto CEI, tomamos metodológicamente al centro escolar como unidad de análisis en el trabajo de campo. El cuestionario se pasó a los 18 centros implicados y en 4 de ellos realizamos el estudio de casos: dos de educación Infantil/Primaria y dos de Secundaria. La metodología utilizada en la recogida y tratamiento de datos combina técnicas cuantitativas y cualitativas para dar respuesta al objetivo principal de la investigación. Dicho objetivo se focaliza en analizar cómo a través de las políticas de transferencia de tecnologías al sistema escolar se transforma la organización en la que se desarrolla la práctica docente.Los resultados destacan aspectos relacionados con la contribución de las TIC a la modernización de la educación. El profesorado valora positivamente el programa CEI, porque con estas tecnologías pueden aproximarse más a lo que hoy demanda el alumnado así como a los sus diferentes ritmos de aprendizaje. Sin embargo, los encuestados muestran reticencias ante las políticas que sustentan el programa que se limita a la dotación de medios. De los casos analizados se desprende que las interacciones en el seno organizativo interfieren y determinan.

    Full Text Available The increasing of investment attractiveness of an enterprise for external and internal investors and efficient management of investments play an important role in ensuring the enterprise competitiveness in the market. The purpose of the article is to analyze the essence, features of formation and activation of investment activity of a trade enterprise and the problems it faces in this activity. There proposed the following definition of investments: these are all types of money, property and intellectual contributions aimed to obtain an economic or social effect in the future with regard to possible risks. The effectiveness of using investments is reflected in such final results as the financial condition of the enterprise, its competitiveness, availability of new prospects, and capitalization of the market value of the enterprise, which can be ensured not by increasing the absolute value of capital investments but by achieving greater efficiency per unit of capital. The investment activity of the enterprise implies the existence of a clearly formulated and achievable goal, which is the basis of its own development, and requires the development of a comprehensive investment strategy. The authors developed methodological approaches to improving investment activities of trade enterprises; substantiated the leading role of the state in enhancing investment activities of trade enterprises and creating conditions for effective implementation of the enterprise investment potential. The proposals formulated in the work will help to increase the competitiveness of domestic trade enterprises.

    A steady expansion of nuclear capacity in the European Community is one of the major ways of preventing unacceptable rises in oil imports. Over the period 1978 to 1985, the creation of the necessary nuclear capacity will require about Pound42000 million, and to help utilities Euratom is prepared to provide loans up to 20 per cent of the total investment cost of a project. The purpose is to complement, not replace, traditional financing resources. Fuel cycle facilities may be prominent in future loans. (U.K.)

    By introducing an exhaustible resource into an AK growth model, we can identify the determinants of the scale of green investment needs and its impact on capital accumulation dynamics. The role of green capital in the transition to a low-carbon economy depends, in particular, on the relative magnitudes of the elasticities of demand for polluting goods and of the substitutability between green capital and natural resources. The impact on the optimal savings rate also depends on the productivity of green capital and on the ability to adapt existing capital

    The RAE-1 spacecraft inversion performed October 31, 1972 is described based upon the in-orbit dynamical data in conjunction with results obtained from previously developed computer simulation models. The computer simulations used are predictive of the satellite dynamics, including boom flexing, and are applicable during boom deployment and retraction, inter-phase coast periods, and post-deployment operations. Attitude data, as well as boom tip data, were analyzed in order to obtain a detailed description of the dynamical behavior of the spacecraft during and after the inversion. Runs were made using the computer model and the results were analyzed and compared with the real time data. Close agreement between the actual recorded spacecraft attitude and the computer simulation results was obtained.

    The OSIRIS instrument onboard the Odin satellite, that was launched on February 20, 2001, is a combined optical spectrograph and infrared imager that obtains profil sets of atmospheric spectra from 280 to 800 nm when Odin scans the terrestrial limb. It has been possible to make a preliminary analysis of the ozone profiles using the Chappuis absorption feature. Three algorithms have been developed for ozone profile inversions from these limb spectra sets. We have dubbed these the Gattinger, Von Savigny-Flittner and DOAS methods. These are being evaluated against POAM and other satellite data. Based on performance, one of these will be selected for the operational algorithm. The infrared imager data have been used by Degenstein with the tomographic inversion procedure to derive ozone concentrations above 60 km. This paper will present some of these initial observations and indicate the best algorithm potential of OSIRIS to make spectacular advances in the study of terrestrial ozone.

    Considered is the operation of a typical magnetron mass spectrometer with an internal ion source and that of an inverse magnetron mass spectrometer with an external ion source. It is found that for discrimination of the same mass using the inverse design of mass spectrometers it is possible to employ either r 2 /r 1 times lesser magnetic fields at equal accelerating source-collector voltages, or r 2 /r 1 higher accelerating voltages at equal magnetic fields, as compared to the typical design (r 1 and r 2 being radii of the internal and external electrodes of the analyser, respectively). The design of an inverse-magnetron mass spectrometer is described. The mass analyzer is formed by a cylindrical electrode of 3 mm diameter and a coaxial tubular cylinder of 55 mm diameter. External to the analyzer is an ionizing chamber at the pressure of up to 5x10 -6 torr. The magnetic field along the chamber axis produced by a solenoid was 300 Oe. At the accelerating voltage of 100 V and mass 28, the spectrometer has a resolution of 30 at a half-peak height

    The mission of Environmental Management's (EM) Office of Technology Development (OTD) Innovation Investment Area is to identify and provide development support for two types of technologies that are developed to characterize, treat and dispose of DOE waste, and to remediate contaminated sites. They are: technologies that show promise to address specific EM needs, but require proof-of-principle experimentation; and (2) already proven technologies in other fields that require critical path experimentation to demonstrate feasibility for adaptation to specific EM needs. The underlying strategy is to ensure that private industry, other Federal Agencies, universities, and DOE National Laboratories are major participants in developing and deploying new and emerging technologies. To this end, about 125 different new and emerging technologies are being developed through Innovation Investment Area's (IIA) two program elements: RDDT ampersand E New Initiatives (RD01) and Interagency Agreements (RD02).

    Information and communication systems can improve the timeliness and quality of decisions. These benefits are strategically important to the utility industry in an era of increasing competition. Because these systems often do not reduce labor cost, however, they can be difficult to evaluate. This report presents a new process for reaching consensus of the value of capital investment in information and communication systems. The results of this project is A Strategic Advocacy Process (ASAP), a methodology that can be used to evaluate investments in information technology. ASAP uses belief graphs to produce a living business case showing facts, assumptions, goals, and metrics for measuring progress toward those goals; shows how to use option pricing theory to quantify the value of managerial flexibility; ASAP uses an organizational impact assessment tool to identify the potential impact of new information systems and how to realize the benefits of managerial flexibility. The ASAP methodology addresses the critical problem of correctly valuing information and communication systems. The methodology offers a way to account for the ''intangible'' value of these systems by recognizing the managerial flexibility these systems can provide in addressing risks and uncovering new business opportunities. Metrics for measuring progress toward new goals can be defined, and plans for achieving the goals can be made. As a result, agreement can be reached on the uses, value, and priority of projects based on a metric other than on labor replacement savings

    Full Text Available Modern conditions of economic systems development have necessitated more precise directions of investment process for the economic growth to accelerate. The precipitous fall of oil prices that occurred in the second half of 2014 weighed heavily on foreign direct investment flows to oilexporting countries. The problem of attracting investment is one of the key problems of economic development. The aim of this study is to analyze and evaluate the shifts in the structure of investments, the study of the structure of investments to the Russian economy. Structural changes result from differences in the growth rate of the elements forming an economic system. An integral coefficient has been used for evaluation of structural changes. Multiple regression was used to analyze the impact of various factors on the change in structure of investment. The regression coefficients in the model give quantitative assessment of the pace of change in the structure as it depends on a specific factor. The model estimation shows that the variables “share of investments in manufacturing” (positive influence and “share of investments in the health, physical culture, education” (negative influence have the largest t-values. Hence, these two factors influence the structural changes in investments most strongly The evaluation and analysis of the structural shifts may lead to conclusions regarding the efficiency of the structure investment and adjustment of the economic policy.

    The aim of the paper is to investigate the relation between inverse limit of branched manifolds and codimension zero laminations. We give necessary and sufficient conditions for such an inverse limit to be a lamination. We also show that codimension zero laminations are inverse limits of branched manifolds. The inverse limit structure allows us to show that equicontinuous codimension zero laminations preserves a distance function on transversals.

    Full Text Available Este artículo tiene como propósito destacar los aportes que ofrece el Enfoque de las Organizaciones Inteligentes en relación al cambio y al manejo de las resistencias involucrados en la implementación de técnicas de dirección en las PYMES. El método empleado se basó en el análisis de planteamientos de autores de literatura vinculada con el tema. Entre los factores encontrados que operan negativamente para invertir en nuevas herramientas de dirección, cabe destacar: el enfoque de gestión tradicional que prevalece en el sistema de creencias de los propietarios, la cultura organizacional y el desconocimiento de una metodología adecuada para el diagnóstico y administración de los cambios implícitos en la implementación de nuevas tecnologías. Se concluye que entre las respuestas que ofrece el enfoque de las organizaciones inteligentes, resaltan: facilitar procesos de aprendizaje organizacional en el dueño y líderes para involucrar y crear los compromisos necesarios para modelar e impulsar las nuevas tecnologías, intervenir en el sistema humano cultural de manera que el cambio no se perciba como una amenaza sino como una oportunidad para el crecimiento personal y el desarrollo organizacional y considerar la metodología de análisis de flujos para el diagnóstico, planificación y seguimiento de los cambios asociados en la implementación.

    Today's investment decisions in key sectors such as energy, forestry or transport have significant impacts on the levels of greenhouse gas (GHG) emissions over the coming decades. Given the economic and environmental long-term implications of capital investment and retirement, a climate mitigation regime should aim to encourage capital investment in climate-friendly technologies. Many factors affect technology choice and the timing of investment, including investor expectations about future prices and policies. Recent international discussions have focused on the importance of providing more certainty about future climate policy stringency. The design of commitment periods can play a role in creating this environment. This paper assesses how the length of commitment periods influences policy uncertainty and investment decisions. In particular, the paper analyses the relationship between commitment period length and near term investment decisions in climate friendly technology.

    In the early 1990s Latin America became a favoured target for foreign investors as one of the side-effects of the collapse of communism in Eastern Europe and the Soviet Union. The reason is linked to macroeconomic reforms in Latin America and the failure of equivalent reforms in the former communist countries. Latin American state-owned-oil companies have been welcomed as borrowers on the international financial markets. Simultaneously private sector investment in the oil industry has increased. This chapter examines nationalisation and the state oil companies, the financing of the state sector, privatisation, the boosting of oil exploration and security issues. The sustainability of the economic reforms in the region is discussed. (UK)

    Nuclear power plant ownership in the United States has continued its steady trend toward ownership consolidation and removal of assets from rate regulated environments that began in 1998. This is paralleled by changes in companies providing nuclear services and growing talk of building new units. World wide, new nuclear plant construction and related supplier investment is proceeding around the world. The nuclear fuel supply part of the business is seeing interest and excitement that would have been almost inconceivable a decade ago. Nuclear is now increasingly being recognized for its energy, economic and environmental benefits. For investors, this is a time of opportunity. And the opportunity is strongly supported by excellent performance trends and fundamental change sin the US electricity business. But in order to benefit from these changes, investors must remain cautious and be committed to comprehensively and thoroughly understanding the individual and interrelated technical, regulatory and political issues that surround this useful and powerful technology.

    The contribution of the green production to the world production of electricity reached 20.2% in 2011, it means a slight increase in respect to the figure of 2010: 19.8%. Green electricity is the second source of electricity behind fossil energy (67.9%) but before nuclear power (11.7%). The decrease in nuclear power due to the Fukushima accident has automatically benefited green electricity. The figures show the importance of China, China is now the first electricity producer in the world before US and also passed US for the production of green electricity. At the world scale the production of green electricity can break down into: hydro energy (80.5%), wind energy (10.3%), biomass (6.2%), geothermal energy (1.6%) and solar energy (1.4%). The crisis has slowed down the investment in renewable energies in Europe. (A.C.)

  5. Inversion of GPS meteorology data

    Directory of Open Access Journals (Sweden)

    K. Hocke

    Full Text Available The GPS meteorology (GPS/MET experiment, led by the Universities Corporation for Atmospheric Research (UCAR, consists of a GPS receiver aboard a low earth orbit (LEO satellite which was launched on 3 April 1995. During a radio occultation the LEO satellite rises or sets relative to one of the 24 GPS satellites at the Earth's horizon. Thereby the atmospheric layers are successively sounded by radio waves which propagate from the GPS satellite to the LEO satellite. From the observed phase path increases, which are due to refraction of the radio waves by the ionosphere and the neutral atmosphere, the atmospheric parameter refractivity, density, pressure and temperature are calculated with high accuracy and resolution (0.5–1.5 km. In the present study, practical aspects of the GPS/MET data analysis are discussed. The retrieval is based on the Abelian integral inversion of the atmospheric bending angle profile into the refractivity index profile. The problem of the upper boundary condition of the Abelian integral is described by examples. The statistical optimization approach which is applied to the data above 40 km and the use of topside bending angle profiles from model atmospheres stabilize the inversion. The retrieved temperature profiles are compared with corresponding profiles which have already been calculated by scientists of UCAR and Jet Propulsion Laboratory (JPL, using Abelian integral inversion too. The comparison shows that in some cases large differences occur (5 K and more. This is probably due to different treatment of the upper boundary condition, data runaways and noise. Several temperature profiles with wavelike structures at tropospheric and stratospheric heights are shown. While the periodic structures at upper stratospheric heights could be caused by residual errors of the ionospheric correction method, the periodic temperature fluctuations at heights below 30 km are most likely caused by atmospheric waves (vertically

    Full Text Available The paper aims to annotate how selection of equity securities can be made by incorporating sustainability into analysis, and to present review of performance evidence of such an investment strategy. The  authors  reviewed  the  scholarly  literature  and contemporary research on what constitutes a socially responsible investment, what risks are associated with such an investment, and what evidence of its performance are  in  different  markets.  They  hypothesized  that  socially  responsible  investments underperform non‐socially aware investments. This paper provides review of relevant corporate sustainability indicators used in investment analysis. Also, this paper is trying to present evidence of a link between  corporate  social  responsibility  and  shareholder  value.  Research  of performance of socially responsible investment equity indices and funds; mostly show that they underperform conventional ones. This paper aims to examine existing findings on socially responsible investing, and to propose modification of corporate strategies accordingly. This paper provides various insights into implications when incorporating environment, social responsibility, and corporate governance into investment strategies.

  7. Calculating investment potential in South America

    International Nuclear Information System (INIS)

    Smith, J.L.

    1995-01-01

    Taxes and licensing provisions typically increase overall costs for private investors, and therefore impede private investment. In addition, the design and structure of tax systems in each country affect the extent to which financial risks are borne by private investors, rather than by the host government. Tax systems that increase perceived financial risks stemming from unpredictable oil prices, development costs and physical characteristics of undiscovered or undeveloped oil fields raise further impediments to private investment. This analysis focuses on both aspects of the investment climate--risk and return--and the way that investment incentives within three South American countries are influenced by tax and licensing regimes

  8. Real Options Analysis of Electricity Investments

    Energy Technology Data Exchange (ETDEWEB)

    Heggedal, Ane Marte

    2012-07-01

    This thesis utilizes real options analysis for evaluating investment opportunities in the electricity sector. It also formally tests how investors in hydropower plants have included uncertainty when considering their investment opportunities. The real options method applies financial options theory to quantify the value of management flexibility and is chosen due to three important characteristics of investments in the electricity sector. First; the investment is completely or partially irreversible, second; the investor can choose when to invest in the facility, and third; there is uncertainty in several factors affecting the cash flows of the investments. Factors of uncertainty include the development of electricity prices, policies, technological advances, and macroeconomics measures.Four papers are included in this thesis. Paper 1, Upgrading hydropower plants with storage: Timing and capacity choice, presents a valuation framework for deciding when to upgrade an existing hydropower plant and which capacity to choose. The second paper, Transmission capacity between Norway and Germany: A real options analysis, sheds light on when two electricity markets, in this case Norway and Germany, should be connected through a sub sea cable. The investor can choose when to invest and the capacity of the cable, and may also choose to invest sequentially. Paper 3, Optimal timing and capacity choice for pumped hydropower storage, investigates when investment in a pumped hydropower plant with storage should be undertaken and what the capacity of the facility should be. Whereas the three first papers investigate investment opportunities, Paper 4, Uncertain climate policy decisions and investment timing: Evidence from small hydropower plants, studies when investors in small hydropower plants chose to invest. The analyses disclose whether the net present value approach or the real options method best describe the investment decisions made by the investors. Viewing investment

    2014-03-01

    Full Text Available The goal of the article lies in the study of the process of optimisation of the structure of investment resources, development of criteria and stages of optimisation of volumes of investment resources for small enterprises by types of economic activity. The article characterises the process of transformation of investment resources into assets and liabilities of the balances of small enterprises and conducts calculation of the structure of sources of formation of investment resources in Ukraine at small enterprises by types of economic activity in 2011. On the basis of the conducted analysis of the structure of investment resources of small enterprises the article forms main groups of criteria of optimisation in the context of individual small enterprises by types of economic activity. The article offers an algorithm and step-by-step scheme of optimisation of investment resources at small enterprises in the form of a multi-stage process of management of investment resources in the context of increase of their mobility and rate of transformation of existing resources into investments. The prospect of further studies in this direction is development of a structural and logic scheme of optimisation of volumes of investment resources at small enterprises.

    2017-02-01

    Full Text Available Effective investment is a factor for long-term company development. As enhancement of investment attractiveness is a required condition for economic growth and improvement of living standards, it needs to be on the agenda at government and company level. The article’s objective is to study investment attractiveness of food industries in Ukraine over 2012–2015. Investment attractiveness of food industries can be measured by indicators of liquidity, financial sustainability, and profit rate. Basically, food industries in Ukraine are attractive for investment, which is demonstrated by assessment of the financial indicators. The investment attractiveness worsened slightly in 2015 compared with 2014. The essential problems faced by food industries are shortage of internal funds and negative profit rate of all the activities, assets and own capital. Official statistical data and software package SPSS are used to build the dendrogram, allowing for dividing food industries by level of investment attractiveness into three groups: industries with high, medium and low level of investment attractiveness. It is found that meat industry is the one with the highest level of investment attractiveness. Also, investors should look positively at food-canning industry, oil and animal fat industry, flour-milling industry, starch and starch products industry, and other foods industry.

  11. BRICS Investment Policies from PFI Perspective

    Directory of Open Access Journals (Sweden)

    Andrei Sakharov 

    2017-12-01

    Full Text Available The Organisation for Economic Co-operation and Development (OECD Policy Framework for Investment (PFI contains recommendations and best practices in 12 investment-related policy areas, and is widely regarded as the world’s most comprehensive and authoritative instrument on international investment regulation. The topicality of PFI recommendations for OECD members and other countries, including Russia, is dictated by competition in international investment markets. The instrument’s implementation can significantly boost a national jurisdiction’s attractiveness to investors and thus increase its economic competitiveness. The experience of the BRICS countries as large developing economies involved in collaboration with the OECD could be of great value from the standpoint of PFI implementation in Russia. This article examines investment policies of Brazil, India, China and South Africa from the perspective of PFI recommendations. The analysis is organized around four major themes: the general characteristics of investment regimes and investment stimuli, national investment regulation regimes, trade policies and overcoming structural limitations. The analysis forms the basis for recommendations to improve the investment policy regime in Russia

    . We offer the solution of some sort of inverse problem: starting from the fields in the invisibility cloak we directly derive the permittivity and permeability tensors of the cloaking shell. This approach can be useful for finding material parameters for the specified electromagnetic fields......The straightforward method of transformation optics implies that one starts from the coordinate transformation and determines the Jacobian matrix, the fields and material parameters of the cloak. However, the coordinate transformation appears as an optional function: it is not necessary to know it...... in the cloaking shell without knowing the coordinate transformation....

    2017-11-01

    Full Text Available In this paper, we examine whether variation in reproductive investment affects the health of Roma women using a dataset collected through original anthropological fieldwork among Roma women in Serbia. Data were collected in 2014–2016 in several Roma semi-urban settlements in central Serbia. The sample consisted of 468 Roma women, averaging 44 years of age. We collected demographic data (age, school levels, socioeconomic status, risk behaviors (smoking and alcohol consumption, marital status, and reproductive history variables (the timing of reproduction, the intensity of reproduction, reproductive effort and investment after birth, in addition to self-reported health, height, and weight. Data analyses showed that somatic, short-term costs of reproduction were revealed in this population, while evolutionary, long-term costs were unobservable—contrariwise, Roma women in poor health contributed more to the gene pool of the next generation than their healthy counterparts. Our findings appear to be consistent with simple trade-off models that suggest inverse relationships between reproductive effort and health. Thus, personal sacrifice—poor health as an outcome—seems crucial for greater reproductive success.

    2018-03-01

    Inverse design can be a useful strategy for discovering interactions that drive particles to spontaneously self-assemble into a desired structure. Here, we extend an inverse design methodology—relative entropy optimization—to determine isotropic interactions that promote assembly of targeted multicomponent phases, and we apply this extension to design interactions for a variety of binary crystals ranging from compact triangular and square architectures to highly open structures with dodecagonal and octadecagonal motifs. We compare the resulting optimized (self- and cross) interactions for the binary assemblies to those obtained from optimization of analogous single-component systems. This comparison reveals that self-interactions act as a "primer" to position particles at approximately correct coordination shell distances, while cross interactions act as the "binder" that refines and locks the system into the desired configuration. For simpler binary targets, it is possible to successfully design self-assembling systems while restricting one of these interaction types to be a hard-core-like potential. However, optimization of both self- and cross interaction types appears necessary to design for assembly of more complex or open structures.

  17. LHC Report: 2 inverse femtobarns!

    CERN Multimedia

    Mike Lamont for the LHC Team

    2011-01-01

    The LHC is enjoying a confluence of twos. This morning (Friday 5 August) we passed 2 inverse femtobarns delivered in 2011; the peak luminosity is now just over 2 x1033 cm-2s-1; and recently fill 2000 was in for nearly 22 hours and delivered around 90 inverse picobarns, almost twice 2010's total.   In order to increase the luminosity we can increase of number of bunches, increase the number of particles per bunch, or decrease the transverse beam size at the interaction point. The beam size can be tackled in two ways: either reduce the size of the injected bunches or squeeze harder with the quadrupole magnets situated on either side of the experiments. Having increased the number of bunches to 1380, the maximum possible with a 50 ns bunch spacing, a one day meeting in Crozet decided to explore the other possibilities. The size of the beams coming from the injectors has been reduced to the minimum possible. This has brought an increase in the peak luminosity of about 50% and the 2 x 1033 cm...

  18. Inverse problems in systems biology

    Engl, Heinz W; Lu, James; Müller, Stefan; Flamm, Christoph; Schuster, Peter; Kügler, Philipp

    2009-01-01

    Systems biology is a new discipline built upon the premise that an understanding of how cells and organisms carry out their functions cannot be gained by looking at cellular components in isolation. Instead, consideration of the interplay between the parts of systems is indispensable for analyzing, modeling, and predicting systems' behavior. Studying biological processes under this premise, systems biology combines experimental techniques and computational methods in order to construct predictive models. Both in building and utilizing models of biological systems, inverse problems arise at several occasions, for example, (i) when experimental time series and steady state data are used to construct biochemical reaction networks, (ii) when model parameters are identified that capture underlying mechanisms or (iii) when desired qualitative behavior such as bistability or limit cycle oscillations is engineered by proper choices of parameter combinations. In this paper we review principles of the modeling process in systems biology and illustrate the ill-posedness and regularization of parameter identification problems in that context. Furthermore, we discuss the methodology of qualitative inverse problems and demonstrate how sparsity enforcing regularization allows the determination of key reaction mechanisms underlying the qualitative behavior.

  19. Small hydro in Ukraine: To invest or not to invest?

    Energy Technology Data Exchange (ETDEWEB)

    Loechen, Liv Arntzen

    2011-07-01

    The vast and unexploited renewable energy potential and the introduction of green tariffs in 2009 have made Ukraine an attractive location for investors within the renewable energy sector. The Green Tariff system offers developers and investors the highest feed-in tariffs in Eastern Europe, and thus far covers alternative energy production from biomass, biogas, wind power plants and hydropower plants. Ukraine has a history in both large- and small hydro production. Whereas the potential of the country's big rivers is now to a great extent exploited, this is not the case for the smaller watercourses. Ukraine is well endowed with small rivers, approximately 60,000 of which can be classified as 'very small'. Most of these are located in the western part of the country, near the Carpathian Mountains. However, despite the natural potential, foreign investors should be aware of the potential risks and hurdles. The country has a huge problem with corruption, and the process of obtaining licenses is not straight forward. On the whole, it can be worthwhile exploring the possibilities of small hydro production in Ukraine for those who can deal with a high level of risk and uncertainty. If not, one would be better advised to look for investment locations elsewhere.(auth)

    2001-01-01

    The purpose of this text is to present the theory and mathematics of inverse scattering, in a simple way, to the many researchers and professionals who use it in their everyday research. While applications range across a broad spectrum of disciplines, examples in this text will focus primarly, but not exclusively, on acoustics. The text will be especially valuable for those applied workers who would like to delve more deeply into the fundamentally mathematical character of the subject matter.Practitioners in this field comprise applied physicists, engineers, and technologists, whereas the theory is almost entirely in the domain of abstract mathematics. This gulf between the two, if bridged, can only lead to improvement in the level of scholarship in this highly important discipline. This is the book''s primary focus.
