    We study the endogenous Stackelberg relations in a dynamic market. We analyze a twice-repeated duopoly where, in the beginning, each firm chooses either a quantity-sticky production mode or a quantity-flexible production mode. The size of the market becomes observable after the first period. In the second period, a firm can adjust its quantity if, and only if, it has adopted the flexible mode. Hence, if one firm chooses the sticky mode whilst the other chooses the flexible mode, then they respectively play the roles of a Stackelberg leader and a Stackelberg follower in the second marketing period. We compute the supply quantities at equilibrium and the corresponding expected profits of the firms. We also analyze the effect of the slope parameter of the demand curve on the expected supply quantities and on the profits.

    Full Text Available Interactions among selfish users sharing a common transmission channel can be modeled as a noncooperative game using the game theory framework. When selfish users choose their transmission probabilities independently without any coordination mechanism, Nash equilibria usually result in a network collapse. We propose a methodology that transforms the noncooperative game into a Stackelberg game. Stackelberg equilibria of the Stackelberg game can overcome the deficiency of the Nash equilibria of the original game. A particular type of Stackelberg intervention is constructed to show that any positive payoff profile feasible with independent transmission probabilities can be achieved as a Stackelberg equilibrium payoff profile. We discuss criteria to select an operating point of the network and informational requirements for the Stackelberg game. We relax the requirements and examine the effects of relaxation on performance.

    Full Text Available We first analyze quality and price decisions in a supply chain with two Stackelberg games: Manufacturer’s Stackelberg (MS and Supplier’s Stackelberg (SS. Then, we investigate how equilibrium solutions are influenced by proposed quality improvement policies: coordination and manufacturer’s involvement. Also, we derive the conditions under which the policies can be implemented in both MS and SS strategies. Numerical experiments illustrate the problems and several related issues are discussed. The results suggest that proposed quality improvement policies can realize Pareto improvement for the supply chain performance.

    The Stackelberg equilibrium is a solution concept that describes optimal strategies to commit to: Player~1 (the leader) first commits to a strategy that is publicly announced, then Player~2 (the follower) plays a best response to the leader's choice. We study Stackelberg equilibria in finite...... sequential (i.e., extensive-form) games and provide new exact algorithms, approximate algorithms, and hardness results for finding equilibria for several classes of such two-player games....

    Full Text Available This paper formulates an integrated inventory model that allows Stackelberg game policy for optimizing joint total cost of a vendor and buyer system. After receiving the lot, the buyer commences an inspection process to determine the defective items. All defective items the buyer sends to vendor during the receiving of the next lot. Due to increasing number of shipments fixed and variable transportation, as well as carbon emissions, are considered, which makes the model sustainable integrated model forever. To reduce the setup cost for the vendor, a discrete setup reduction is considered for maximization more profit. The players of the integrated model are with unequal power (as leader and follower and the Stackelberg game strategy is utilized to solve this model for obtaining global optimum solution over the finite planning horizon. An illustrative numerical example is given to understand this model clearly.

    Full Text Available With the integration of physical plant and network, cyber-physical systems (CPSs are increasingly vulnerable due to their distributed and hierarchical framework. Stackelberg interdependent security game (SISG is proposed for characterizing the interdependent security in CPSs, that is, the interactions between individual CPSs, which are selfish but nonmalicious with the payoff function being formulated from a cross-layer perspective. The pure-strategy equilibria for two-player symmetric SISG are firstly analyzed with the strategy gap between individual and social optimum being characterized, which is known as negative externalities. Then, the results are further extended to the asymmetric and m-player SISG. At last, a numerical case of practical experiment platform is analyzed for determining the comprehensively optimal security configuration for administrator.

  9. Chaotic dynamics in nonlinear duopoly Stackelberg game with heterogeneous players

    2018-02-01

    In this paper, a nonlinear duopoly Stackelberg game of competition on output is concerned. In consideration of the effects of difference between plan products and actual products, the two heterogeneous players always adopt suitable strategies which can improve their benefits most. In general, status of each firm is unequal. As the firms take strategies sequentially and produce simultaneously, complex behaviors are brought about. Numerical simulation presents period doubling bifurcation, maximal Lyapunov exponent and chaos. Moreover, an appropriate method of chaos controlling is applied and fractal dimension is analyzed as well.

  10. Stackelberg Game for Product Renewal in Supply Chain

    Full Text Available The paper studied the process of product renewal in a supply chain, which is composed of one manufacturer and one retailer. There are original product and renewal product in the supply chain. A market share shift model for renewal product was firstly built on a increment function and a shift function. Based on the model, the decision-making plane consisting of two variables was divided into four areas. Since the process of product renewal was divided into two stages, Stackelberg-Nash game model and Stackelberg-merger game model could be built to describe this process. The optimal solutions of product pricing strategy of two games were obtained. The relationships between renewal rate, cost, pricing strategy, and profits were got by numerical simulation. Some insights were obtained from this paper. Higher renewal rate will make participants’ profits and total profit increase at the same margin cost. What is more important, the way of the optimal decision making of the SC was that RP comes onto the market with a great price differential between OP and RP.

    This paper extends the work of Wang (2002) by considering a differentiated Stackelberg model, when the leader firm is an inside innovator and licenses its new technology by three options, that is, fixed-fee licensing, royalty licensing, and two-part tariff licensing. The main contributions and conclusions of this paper are threefold. First of all, this paper derives a very different result from Wang (2002). We show that, with a nondrastic innovation, royalty licensing is always better than fixed-fee licensing for the innovator; with a drastic innovation, royalty licensing is superior to fixed-fee licensing for small values of substitution coefficient d; however when d becomes closer to 1, neither fee nor royalty licensing will occur. Secondly, this paper shows that the innovator is always better off in case of two-part tariff licensing than fixed-fee licensing no matter what the innovation size is. Thirdly, the innovator always prefers to license its nondrastic innovation by means of a two-part tariff instead of licensing by means of a royalty; however, with a drastic innovation, the optimal licensing strategy can be either a two-part tariff or a royalty, depending upon the differentiation of the goods.

  13. Quantum Stackelberg duopoly in the presence of correlated noise

    2010-01-01

    We study the influence of entanglement and correlated noise using correlated amplitude damping, depolarizing and phase damping channels on the quantum Stackelberg duopoly. Our investigations show that under the influence of an amplitude damping channel a critical point exists for an unentangled initial state at which firms get equal payoffs. The game becomes a follower advantage game when the channel is highly decohered. Two critical points corresponding to two values of the entanglement angle are found in the presence of correlated noise. Within the range of these limits of the entanglement angle, the game is a follower advantage game. In the case of a depolarizing channel, the payoffs of the two firms are strongly influenced by the memory parameter. The presence of quantum memory ensures the existence of the Nash equilibrium for the entire range of decoherence and entanglement parameters for both the channels. A local maximum in the payoffs is observed which vanishes as the channel correlation increases. Moreover, under the influence of the depolarizing channel, the game is always a leader advantage game. Furthermore, it is seen that the phase damping channel does not affect the outcome of the game.

  16. Dynamic Stackelberg game model for water rationalization in drought emergency

    2014-09-01

    In water resource management, in case of a limited resource, there is a conflict situation between different consumers. In this paper, a dynamic game-theoretical model is suggested for the solution of such conflict. Let us suppose that in a region, water supply is based on a given aquifer, from which a quantity of effective reserve can be used without damaging the aquifer, and a long drought is foreseen. The use of water is divided between the social sector represented by the local authority, and the production sector, in our case, simplified to a single agricultural producer using water for irrigation; they are the players in the game. For a fixed time period, every day, a given amount is available, from which first the authority, then the producer takes a proportion, which corresponds to the strategy choices of the players. A price function is given, which depends on the total available reserve, the payoffs of both players are quantified as their net incomes for the whole period: for the producer: profit from selling the product minus price of water and tax paid, for the authority: tax received plus the gain for the authority from selling the water bought to the social sector minus price of water purchased. A solution (equilibrium) of the game consists of such strategy choices of both players, with which each player maximizes her/his total payoff (over the whole time horizon of the game) provided that the other player also maximizes her/his own payoff. In the paper, in a mathematical model for the above conflict situation, a deterministic continuum-strategy two-player discrete-time dynamic Stackelberg game with fixed finite time duration and closed-loop information structure is proposed, where the authority is “leader” and the producer is “follower”. The algorithms for the solution of the game are based on recent theoretical results of the authors. Illustrative numerical examples are also given.

  17. On Stackelberg and Inverse Stackelberg Games and Their Applications in the Optimal Toll Design Problem, the Energy Markets Liberalization Problem, and in the Theory of Incentives

    International Nuclear Information System (INIS)

    Stankova, K.

    2009-01-01

    Inverse (or reverse) Stackelberg games have become the subject of recent game theory research, as a special type or as an extension of Stackelberg games. So far, only very little theory about inverse Stackelberg games is available and the available theory is still in its infancy. In this thesis we focus on theoretically solving such problems and we propose to treat several challenging problems in various fields inside this framework. In Stackelberg games a so-called leader determines actions for one or more so-called followers. The problem of finding an optimal strategy for the leader in these games is in general extremely hard to solve, and often even completely unsolvable. Starting from simple static problems and proceeding to more difficult dynamic ones, we show how to find the optimal strategy for the leader in a heuristic manner. In this thesis, the application of game theory is proposed in the following domains: The optimal toll design problem, the electricity markets liberalization problem, and the theory of incentives. The optimal toll design problem is a game of the Stackelberg type in which a road authority acts as the leader and drivers in the road network act as the followers. The road authority sets tolls on some of the links in the network in order to maximize its objective function, while the drivers make their travel decisions in order to minimize their perceived travel costs. If the toll that the road authority sets is traffic-flow invariant, the problem is the 'classical' Stackelberg game; if the toll is traffic-flow dependent, the problem is of the inverse Stackelberg type. We determine the optimal traffic-flow dependent toll for the road authority for both static and dynamic variants of the problem. If the solution concept for the drivers' behavior is the deterministic user equilibrium, the problem can be dealt with analytically. If the stochastic user equilibrium applies, numerical methods have to be applied to find a solution. As the problem

    Full Text Available Recently, wireless network technologies were designed for most of the applications. Congestion raised in the wireless network degrades the performance and reduces the throughput. Congestion-free network is quit essen- tial in the transport layer to prevent performance degradation in a wireless network. Game theory is a branch of applied mathematics and applied sciences that used in wireless network, political science, biology, computer science, philosophy and economics. e great challenges of wireless network are their congestion by various factors. E ective congestion-free alternate path routing is pretty essential to increase network performance. Stackelberg game theory model is currently employed as an e ective tool to design and formulate conges- tion issues in wireless networks. is work uses a Stackelberg game to design alternate path model to avoid congestion. In this game, leaders and followers are selected to select an alternate routing path. e correlated equilibrium is used in Stackelberg game for making better decision between non-cooperation and cooperation. Congestion was continuously monitored to increase the throughput in the network. Simulation results show that the proposed scheme could extensively improve the network performance by reducing congestion with the help of Stackelberg game and thereby enhance throughput.

  1. Strong Stackelberg reasoning in symmetric games: An experimental replication and extension

    Directory of Open Access Journals (Sweden)

    Briony D. Pulford

    2014-02-01

    Full Text Available In common interest games in which players are motivated to coordinate their strategies to achieve a jointly optimal outcome, orthodox game theory provides no general reason or justification for choosing the required strategies. In the simplest cases, where the optimal strategies are intuitively obvious, human decision makers generally coordinate without difficulty, but how they achieve this is poorly understood. Most theories seeking to explain strategic coordination have limited applicability, or require changes to the game specification, or introduce implausible assumptions or radical departures from fundamental game-theoretic assumptions. The theory of strong Stackelberg reasoning, according to which players choose strategies that would maximize their own payoffs if their co-players could invariably anticipate any strategy and respond with a best reply to it, avoids these problems and explains strategic coordination in all dyadic common interest games. Previous experimental evidence has provided evidence for strong Stackelberg reasoning in asymmetric games. Here we report evidence from two experiments consistent with players being influenced by strong Stackelberg reasoning in a wide variety of symmetric 3 × 3 games but tending to revert to other choice criteria when strong Stackelberg reasoning generates small payoffs.

    This article analyses export taxes in a Bertrand duopoly with product differentiation, where a home and a foreign firm both export to a third-country market. It is shown that the maximum-revenue export tax always exceeds the optimum-welfare export tax. In a Nash equilibrium in export taxes, the country with the low cost firm imposes the largest export tax. The results under Bertrand duopoly are compared with those under Cournot duopoly. It is shown that the absolute value of the export subsid...

    2014-01-01

    Full Text Available This paper studies channel consisting of a manufacturer and two retailers. As a basis for comparison, the first, multiagent Stackelberg model has been structured based on perfect rationality. Further, fairness preference theory will be embedded in marketing channel multiagent Stackelberg model, and the results show that if the retailers have a jealous fairness preference, the manufacturer will reduce the wholesale price, retailers will increase the effort level, product sales will be increased, and the total channel utility and manufacturers’ utility will be pareto improvement, but the pareto improvement of retailers’ utility is associated with the interval of jealousy fairness preference coefficient. If the retailers have a sympathetic fairness preference, the manufacturer increases wholesale price, retailers reduce the effort level, and the total channel utility, manufacturer’s utility, and retailers’ utility are less than that of the no fairness preference utility.

    Full Text Available In this paper, we establish a dynamic game to allocate CSR (Corporate Social Responsibility to the members of a supply chain. We propose a model of a supply chain in a decentralized state which includes a supplier and a manufacturer. For analyzing supply chain performance in decentralized state and the relationships between the members of the supply chain, we formulate a model that crosses through multiperiods with the help of a dynamic discrete Stackelberg game which is made under two different information structures. We obtain an equilibrium point at which both the profits of members and the level of CSR taken up by supply chains are maximized.

    In the present paper we consider a differentiated-good Stackelberg model, when the follower firm engages in an R&D process that gives an endogenous cost-reducing innovation. The aim is two-fold: the first is to study the case when there is no technology transfer between the innovator and the non-innovator firm (the benchmark case); the second is to study the case when there is a technology transfer between the innovator and the non-innovator firm based on a per-unit royalty licensing contract. The main results are relieved.

    2015-01-01

    Wireless Body Area Network (WBAN) is effectively used in healthcare to increase the value of the patient's life and also the value of healthcare services. The biosensor based approach in medical care system makes it difficult to respond to the patients with minimal response time. The medical care unit does not deploy the accessing of ubiquitous broadband connections full time and hence the level of security will not be high always. The security issue also arises in monitoring the user body function records. Most of the systems on the Wireless Body Area Network are not effective in facing the security deployment issues. To access the patient's information with higher security on WBAN, Game Theory with Stackelberg Security Equilibrium (GTSSE) is proposed in this paper. GTSSE mechanism takes all the players into account. The patients are monitored by placing the power position authority initially. The position authority in GTSSE is the organizer and all the other players react to the organizer decision. Based on our proposed approach, experiment has been conducted on factors such as security ratio based on patient's health information, system flexibility level, energy consumption rate, and information loss rate. Stackelberg Security considerably improves the strength of solution with higher security. PMID:26759829

    Firms need to incur substantial sunk costs to break in foreign markets, yet many give up exporting shortly after their first experience, which typically involves very small sales. Conversely, other new exporters shoot up their foreign sales and expand to new destinations. We investigate a simple theoretical mechanism that can rationalize these patterns. A firm discovers its profitability as an exporter only after actually engaging in exporting. The profitability is positively correlated over ...

  10. Computing the Stackelberg/Nash equilibria using the extraproximal method: Convergence analysis and implementation details for Markov chains games

    Directory of Open Access Journals (Sweden)

    Trejo Kristal K.

    2015-06-01

    Full Text Available In this paper we present the extraproximal method for computing the Stackelberg/Nash equilibria in a class of ergodic controlled finite Markov chains games. We exemplify the original game formulation in terms of coupled nonlinear programming problems implementing the Lagrange principle. In addition, Tikhonov’s regularization method is employed to ensure the convergence of the cost-functions to a Stackelberg/Nash equilibrium point. Then, we transform the problem into a system of equations in the proximal format. We present a two-step iterated procedure for solving the extraproximal method: (a the first step (the extra-proximal step consists of a “prediction” which calculates the preliminary position approximation to the equilibrium point, and (b the second step is designed to find a “basic adjustment” of the previous prediction. The procedure is called the “extraproximal method” because of the use of an extrapolation. Each equation in this system is an optimization problem for which the necessary and efficient condition for a minimum is solved using a quadratic programming method. This solution approach provides a drastically quicker rate of convergence to the equilibrium point. We present the analysis of the convergence as well the rate of convergence of the method, which is one of the main results of this paper. Additionally, the extraproximal method is developed in terms of Markov chains for Stackelberg games. Our goal is to analyze completely a three-player Stackelberg game consisting of a leader and two followers. We provide all the details needed to implement the extraproximal method in an efficient and numerically stable way. For instance, a numerical technique is presented for computing the first step parameter (λ of the extraproximal method. The usefulness of the approach is successfully demonstrated by a numerical example related to a pricing oligopoly model for airlines companies.

    This paper studies the importance of export spillovers in a firm's decision to enter specific export markets and extends the current state of the literature by assessing different mechanisms through which they may occur, namely (i) labour movement, (ii) intra-industry spillovers and (iii) inter......-industry linkages. We do so by exploiting a unique data set covering the universe of manufacturing firms in Denmark for the period 1995–2006 which combines transaction-level export data, firm accounting data, employer–employee linked data and information from yearly input–output tables. We corroborate...... the literature on export spillovers by presenting robust evidence of destination-specific export spillovers. The results suggest that labour mobility as well as intra- and inter-industry linkages (backward linkages) are important channels for export spillovers, while presenting heterogeneous effects across firms...

As D2D user equipment (UE can cause interference to cellular UE, scheduling and allocation of channel resources and power of D2D communication need elaborate coordination. In this paper, we propose a joint scheduling and resource allocation scheme to improve the performance of D2D communication. We take UE rate and UE fairness into account by performing interference management. First, we construct a Stackelberg game framework in which we group a macrocellular UE, a femtocellular UE, and a D2D UE to form a two-leader one-follower pair. The cellular UE are leaders, and D2D UE is the follower who buys channel resources from the leaders. We analyze the equilibrium of the game and obtain solutions to the equilibrium. Second, we propose an algorithm for joint scheduling of D2D pairs based on their utility. Finally, we perform computer simulations to study the performance of the proposed scheme.

  13. The influence of entanglement and decoherence on the quantum Stackelberg duopoly game

    2007-01-01

    In this paper, we investigate the influence of entanglement and decoherence on the quantum Stackelberg duopoly (QSD) game. It is shown that the first-mover advantage can be weakened or enhanced due to the existence of entanglement for the QSD game without decoherence. The influence of decoherence induced by the amplitude damping and the phase damping are explicitly studied in the formalism of Kraus operator representations. We show that the amplitude damping drastically changes the Nash equilibrium of the QSD game and the profits of the two players while the phase damping does not affect the Nash equilibrium and the profits of the two players. It is found that under certain conditions there exists a 'critical point' of the damping parameter for the amplitude damping environment. At the 'critical point' the two players have the same moves and payoffs. The QSD game can change from the first-mover advantage game into the follower-mover advantage game when the damping parameter varies from the left-hand-side regime of the 'critical point' to the right-hand-side regime

    2017-05-01

    In this paper, a cooperation method between wind farm and Electric vehicle battery switch station (EVBSS) was proposed. In the pursuit of maximizing their own benefits, the cooperation between wind farm and EVBSS was formulated as a Stackelberg game model by treating them as decision makers in different status. As the leader, wind farm will determine the charging/discharging price to induce the charging and discharging behavior of EVBSS reasonably. Through peak load shifting, wind farm could increase its profits by selling more wind power to the power grid during time interval with a higher purchase price. As the follower, EVBSS will charge or discharge according to the price determined by wind farm. Through optimizing the charging /discharging strategy, EVBSS will try to charge with a lower price and discharge with a higher price in order to increase its profits. Since the possible charging /discharging strategy of EVBSS is known, the wind farm will take the strategy into consideration while deciding the charging /discharging price, and will adjust the price accordingly to increase its profits. The case study proved that the proposed cooperation method and model were feasible and effective.

    This paper provides a direct test of how fixed export costs and productivity jointly determine firm-level export behavior. Using Chilean data, we construct indices of fixed export costs for each industry-region-year triplet and match them to domestic firms. Our empirical results show that firms facing higher fixed export costs are less likely to export, while those with higher productivity export more. These outcomes are the foundation of the widely-used sorting mechanism in the trade models ...

    Australia is a major uranium supplier. Uranium is exported under conditions laid down to avoid any nuclear proliferation. On 24 May 1977 the Prime Minister had stated the main elements of Australian policy: the strengthening of the system of international safeguards and the selection of importing countries. (Non-nuclear weapon states must be Contracting Parties to the NPT. Nuclear weapon states must undertake not to use Australian uranium for this purpose). Australia retains property of the uranium up to the UF 6 stage (uranium hexafluoride) in the fuel cycle; it reserves the right to stop any export if the importing country no longer complies with AIEA Safeguards. Any transfer to a third country, any irradiated fuel reprocessing, requires Australia's prior agreement. Finally, importing countries must satisfy physical protection conditions. (NEA) [fr

  19. Choosing the optimum burnup

    International Nuclear Information System (INIS)

    Geller, L.; Goldstein, L.; Franks, W.A.

    1986-01-01

    This paper reviews some of the considerations utilities must evaluate when going to higher discharge burnups. The advantages and disadvantages of higher discharge burnups are described, as well as a consistent approach for evaluating optimum discharge burnup and its comparison to current practice. When an analysis is performed over the life of the plant, the design of the terminal cycles has significant impact on the lifetime savings from higher burnups. Designs for high burnup cycles have a greater average inventory value in the core. As one goes to higher burnup, there is a greater likelihood of discarding a larger value in unused fuel unless the terminal cycles are designed carefully. This effect can be large enough in some cases to wipe out the lifetime cost savings relative to operating with a higher discharge burnup cycle

  20. An Optimum Currency Crisis

    Paolo Pasimeni

    2014-12-01

    Full Text Available This paper presents an ex-post assessment of the current situation of the EMU in light of the conditions prescribed by the theory of Optimum Currency Areas (OCA. The analysis shows that some of those conditions were satisfied at the inception of the EMU, others were missing at the beginning, but improved over time as expected by the endogenous approach to the OCA theory. The common fiscal capacity was the main missing element of the initial construction of the Eurozone, and still is. The common budget is so exiguous that its effectiveness as shock absorption mechanism is negligible. The analysis then shows how some of the concerns raised on the eve of the euro did actually materialize, even if not immediately. First, in its first decade the Eurozone did not experience major turbulences, because growing financial integration was compensating the need for fiscal transfers, channelling the excess of saving from the ‘core’ to the ‘periphery’. Second, the mechanism generated record-high private indebtedness in the ‘periphery’ and exposure of the banks in the ‘core’, making the whole system more fragile as it relied upon financial markets’ stability. Third, once the long-feared shock hit, the mechanism proved weak and non-resilient. The inherent weaknesses of the EMU became evident. Fourth, as it had been foreseen, the cost of the adjustment after the shock fell mainly on labour, with much higher and longer unemployment in the Eurozone than both non-Eurozone EU and the US. Fifth, as the theory suggested, the lack of common mechanisms of adjustment dramatically increased the socio-economic divergences within the EMU. The paper finally presents a simulation for a common budget of the Eurozone, linked to the relative current account positions of the member states.

    2012-01-01

    Full Text Available Solving the problem of stabilizing the economy is directly tied to the necessity of keeping the main macroeconomic variables stable. However, macroeconomic stability is not in the general case a purely fiscal or a purely monetary problem. How the central bank and the government interact is of principle importance. We investigate the impact of macroeconomic policies on the dynamics of the exchange rate, inflation, output and stabilization fund and consider different forms of strategic interaction between the government and the central bank. In this paper we build a stylized model of an export-oriented economy. We use numerical examples for our analysis and practical conclusions. The effective interaction of fiscal and monetary policies is possible under a cooperative Stackelberg game interaction with the government as leader. It is shown that the independence of the central bank does not play a crucial role.

While exporting plants have substantially higher productivity levels, we find no evidence that exporti...

  6. Sudanese live sheep and mutton exports competitiveness

    Directory of Open Access Journals (Sweden)

    Babiker Idris Babiker

    2011-01-01

    Full Text Available The livestock sector of Sudan provides livelihood for about 17% of the population. Sudanese livestock products meet the domestic demand for meat in addition to a substantial excess for export amounting to about 22% of total country exports. It contributes about 19% of GDP. Sheep marketing in Sudan is characterised by traditional operations and is informally organised, although, recently there are great efforts by the formal livestock authorities to organise some secondary and terminal livestock markets. These markets are deficient in basic infrastructures and systematic marketing research. The system as a whole is faced by various complex obstacles and constraints, which decrease the contribution of livestock in general, and sheep in particular, to the national economy, and suppress the optimum exploitation of this resource. These obstacles are represented in the lack of transportation networks that connect the production and consumption centres to break the seasonality of supply that creates shortages and high prices at the consumption centres. This paper employs the policy analysis matrix (PAM technique to examine the Sudanese live sheep and mutton competitiveness in the international market. The results indicated that the market price was greater than the border price implying a positive incentive as an implicit subsidy to the live sheep exporter. The mutton exporters were found subsidised as well. The international value added (IVA indicted a positive foreign exchange earnings or savings. Exported live sheep and mutton coefficient of competitiveness (CIC implied that sheep and mutton exports are profitable and internationally competitive.

    2018-01-01

    Full Text Available The paper technically proposes a newly secure scheme for simultaneous wireless power and information transfer (SWIPT frameworks. We take into account an orthogonal frequency division multiplexing (OFDM-based game which is in relation to a multi-input multi-output multi-antenna Eavesdropper (MIMOME strategy. The transceiver is generally able to witness the case imperfect channel state information (ICSI at the transmitter side. Transferring power and information are conducted via orthogonally provided sub-carriers. We propose a two-step Stackelberg game to optimise the Utility Functions of both power and information parts. The price for the first stage (in connection with information is the total power of the other sub-carriers over which the energy is supported. In this stage, the sum secrecy rate should be essentially maximised. The second level of the proposed Stackelberg game is in association with the energy part. In this stage, the price essentially is the total power of the other sub-carriers over which the information is transferred. In this stage, additionally, the total power transferred is fundamentally maximised. Subsequently, the optimally and near-optimally mathematical solutions are derived, for some special cases such as ICSI one. Finally, the simulations validate our scheme as well, authenticating our contribution’s tightness and efficiency.

    A Renewable Energy Exporters Network (REEN) has recently been established, following a meeting of renewable energy exporters and government agencies on 30 October 2000. REEN will assist the Australian renewable energy industry to take advantage of the opportunities offered by the burgeoning global market for renewable energy goods and services. Recent estimates of the significant potential global growth is renewable energy demand have reinforced the industry and Government's view that, in the medium to long-term, growth in the Australian renewable energy industry will largely depend on capturing export market share. Expanding the export market was identified as a crucial component in the Renewable Energy Action Agenda, developed jointly by industry and Government and released in June 2000. It was estimated that, for the industry to achieve its vision of sales of $4 billion per year by 2010, exports would need to comprise approximately 50% of the forecast growth in sales. As such, the need for a specific export strategy for the Australian renewable energy industry was recognised in the Action Agenda, and the establishment of the REEN is one of the first initiatives undertaken as part of the Renewable Energy Export Strategy. The REEN comprises approximately 50 export-ready renewable energy companies, the Department of Industry, Science and Resources, Austrade, and Stage Government agencies such as NSW's Sustainable Energy Development Authority. The Export Network will operate electronically, with face-to-face meetings held as appropriate. The Department of Industry, Science and Resources will facilitate the Export Network and has published a website at www.isr.gov.au/industry/reen. The site includes: a members directory; a discussion forum; information on opportunities to showcase Australian renewable; energy products and services; and Iinks to sites containing information that may be useful to renewable energy exporters.

    Jäkel, Ina Charlotte; Sørensen, Allan

    This paper provides new evidence on manufacturing firms' output prices: in Denmark, on average, exported varieties are sold at a lower price (i.e. a negative exporter price premium) relative to only domestically sold varieties. This finding stands in sharp contrast to previous studies, which have...... found positive exporter price premia. We also document that the exporter price premium varies substantially across products (both in terms of sign and magnitude). We show that in a standard heterogeneous firms model with heterogeneity in quality as well as production efficiency there is indeed no clear......-cut prediction on the sign of the exporter price premium. However, the model unambiguously predicts a negative exporter price premium in terms of quality-adjusted prices, i.e. prices per unit of quality. This prediction is broadly borne out in the Danish data: while the magnitude of the premium varies across...

    This paper considers a decentralized supply chain in which a single supplier sells a perishable product to a single retailer facing uncertain demand. We assume that the supplier and the retailer are both risk averse and utilize Conditional Value at Risk (CVaR), a risk measure method which is popularized in financial risk management, to estimate their risk attitude. We establish a buyback policy model based on Stackelberg game theory under considering supply chain members' risk preference and get the expressions of the supplier's optimal repurchase price and the retailer's optimal order quantity which are compared with those under risk neutral case. Finally, a numerical example is applied to simulate that model and prove related conclusions.

    It had been studied the effect of the ionizing radiation (gamma) in mangoes for exportation, simulating the stage of preservation of the fruit during its transport, through the refrigeration in cold chamber. In a first stage they had been analyzed through loss of weight, pH, treatable acidity, soluble solid, texture and decomposition. Later, sensorial analyses had been become fulfilled (alterations of color, odor, flavor, texture). The assays had been carried through in two stadiums of maturation of the fruits, that is, 2 and 3, with the intention of studying optimum point of harvest for the best dosage of irradiation. The results disclose together that the treatment of the mangoes Tommy Atkins in the dose of 0,75 kGy was significant, with the fruit in stadium 2, for the retardation of the matureness and consequent profit of time for the exportation.

    2011-01-01

    After the Fukushima accident occurred in March 2011, reform of Japan's basic energy plan and energy supply system was reported to be under discussion such as to reduce dependence on nuclear power. Planning of energy policy should be considered based on four evaluation indexes of 'economics'. 'environmental effects', 'stable supply of energy' and 'sustainability'. 'Stable supply of energy' should include stability of domestic energy supply infrastructure against natural disasters in addition to stable supply of overseas resources. 'Sustainability' meant long-term availability of resources. Since there did not exist an almighty energy source and energy supply system superior in terms of every above-mentioned evaluation index, it would be wise to use combining various energy sources and supply system in rational way. This combination lead to optimum energy mix, so-called 'Energy Best Mix'. The author evaluated characteristics of energy sources and energy supply system in terms of four indexes and showed best energy mix from short-, medium- and long-term perspectives. Since fossil fuel resources would deplete anyhow, it would be inevitable for human being to be dependent on non-fossil energy resources regardless of greenhouse effects. At present it would be difficult and no guarantee to establish society fully dependent on renewable energy, then it would be probable to need utilization of nuclear energy in the long term. (T.

    It is shown that the swings and roundabouts of the Asian economic shake out and Australian dollar devaluation are starting to work their way through the Australian export coal market. Perhaps somewhat surprisingly, at this stage the results are not proving to be as bad as were at first predicted by some market watchers. Export revenue and tonnages are up 12% for the year to July 98. Coal exports totaling $9.5 billion left Australia's shores in the 12 months confirming coal as Australia's single largest export revenue earner. Sales volumes in the present financial year are still increasing, the market being driven by steadily increasing Asian demand for steaming coal from places like Korea, Malaysia, Thailand and the Philippines

    International Nuclear Information System (INIS)

    Averyt, W.F.

    1992-01-01

    In 1987 Hydro-Quebec exported over 16 TWh to New England and New York and it plans to export 3,500 MW of firm power, not interruptible, by the early 2000s. It estimates that the northeast US market has an additional potential of 9,000 MW. The export market has become more difficult than anticipated. The federal/state regulatory framework for electricity generation was changing - it encouraged small scale generation, cogeneration and conservation which decreased demand. Demand for power imports has also been influenced by pricing judgements and avoided costs. Environmental concerns and Native protest have become increasingly important factors affecting future export sales and hence the proposed James Bay developments. Regulatory changes affecting supply and pricing, concerns about continental impacts, about further development of electrical sources together with Native requirements will further complicate the Quebec-US electricity trade.

  11. Canada's reactor exports

    International Nuclear Information System (INIS)

    Morrison, R.W.

    1981-01-01

    A brief sketch of the development of Canada's nuclear exports is presented and some of the factors which influence the ability to export reactors have been identified. The potential market for CANDUs is small and will develop slowly. The competition will be tough. There are few good prospects for immediate export orders in the next two or three years. Nonetheless there are reasonable opportunities for CANDU exports, especially in the mid-to-late 1980s. Such sales could be of great benefit to Canada and could do much to sustain the domestic nuclear industry. Apart from its excellent economic and technical performance, the main attraction of the CANDU seems to be the autonomy it confers on purchasing countries, the effectiveness with which the associated technology can be transferred, and the diversification it offers to countries which wish to reduce their dependence on the major industrial suppliers. Each sales opportunity is unique, and marketing strategy will have to be tailored to the customer's needs. Over the next decade, the factors susceptible to Canadian government action which are most likely to influence CANDU exports will be the political commitment of the government to those reactor exports, the performance established by the four 600 MWe CANDUs now nearing completion, the continuing successful operation of the nuclear program in Ontario, and the co-ordination of the different components of Canada's nuclear program (AECL, nuclear industry, utilities, and government) in putting forth a coherent marketing effort and following through with effective project management

  12. Indonesian coal export potential

    1993-01-01

    Indonesia's coal mining sector is expanding rapidly. Much of the increase in coal production since the mid-1980s has been exported. Indonesian coal mining companies have large expansion programs and continuing strong export growth is projected for the remainder of the 1990s. The low mining costs of indonesian coal, together with proximity to Asian markets, mean that Indonesia is well placed to compete strongly with other thermal coal exporters and win market share in the large and expanding thermal coal market in Asia. However, there is significant uncertainty about the likely future level of Indonesia's exportable surplus of coal. The government's planned expansion in coal fired power generation could constrain export growth, while the ability of producers to meet projected output levels is uncertain. The purpose in this article is to review coal supply and demand developments in Indonesia and, taking account of the key determining factors, to estimate the level of coal exports from Indonesia to the year 2000. This time frame has been chosen because all currently committed mine developments are expected to be on stream by 2000 and because it is difficult to project domestic demand for coal beyond that year. 29 refs., 8 tabs., 7 figs

  13. An exporter's checklist

    International Nuclear Information System (INIS)

    Englot, P.

    1995-01-01

    The benefits of exporting goods and services was discussed. The article listed a summary of issues which could be referred to to assist with the development of an effective plan to export. Some issues to consider were: (1) analysis of the export market, such as political and cultural issues, local legislation, competition, infrastructure, transportation and logistics, (2) internal issues, such as people, equipment, capital, time, understanding of the risks, relocation and identification of all costs, (3) sources of support such as banks, government and transporters, (4) development of a solid payment plan. It was concluded that exporting was not for the faint-hearted. It can be expensive, and time consuming, however, if approached in the right spirit it could be highly rewarding. As a rule of thumb, the probability of success was said to be directly related to the amount of effort put into the preparatory phase. Potential exporters were reminded of the very strong infrastructure that exists in Canada to promote and support export initiatives, including all levels of government, financial institutions, freight forwarders and innumerable consultant/specialists

  14. A Stackelberg Game Approach for Energy Outage-Aware Power Distribution of an Off-Grid Base Station over Multiple Retailers

    2018-03-01

    Full Text Available This paper investigates the problem of power distribution for an off-grid base station (BS that operates sustainably without an electrical grid. We consider that multiple retailers with heterogeneous renewable energy sources (RESs compete to maximize their revenues by individually setting the unit power price. Energy outages (EOs, which cause the power supply to fall below that which is sufficient for ensuring the traffic arrival rate required for the off-grid BS, critically affect the users’ service quality. To minimize EOs and operational expenditure (OPEX, the off-grid BS manages the power supply by reacting to the retailers’ pricing decisions. We analyze the economic benefits of power distribution to the off-grid BS from the perspective of the retailers’ pricing competition, by designing a hierarchical decision-making scheme as a multi-leader single-follower Stackelberg game. We derive a closed form expression for the optimal behavior of the off-grid BS and retailers, based on well-designed utility functions. Finally, numerical results demonstrate the proposed solution with its practical convergence time.

    Events that have transpired in the past few years that have caused renewed concern about the spread of nuclear weapons are reviewed. Many proposals have been made recently for keeping the bomb from spreading. The author feels that the most novel and intriguing of them is the one advanced by Senator Abraham Ribicoff and Steven J. Baker; in their proposal, the world market for nuclear reactors would be divided into precisely defined shares among the industrial nations that now manufacture them for export; each exporter would be guaranteed a certain number of sales annually; and each would pledge not to sell uranium enrichment or plutonium reprocessing technology, as Germany did to Brazil. This might not halt proliferation, but it would give the world a few more years to find a solution

    1988-04-01

    A summary is presented of exports of motor gasoline, middle distillate, aviation turbine fuel, heavy fuel oil, and partially processed oil from Canada for the 1987 calendar year. A discussion of petroleum product imports is included in order to put exports in the context of the overall trade. Exports of the above petroleum products averaged 22,200 m 3 /d in 1987, up 15% from 1986 levels. Exports of middle distillates and aviation fuel had the largest gains in 1987. Export prices for light petroleum products stayed relatively close to USA spot prices. The heavy fuel oil price was below the New York spot price in the beginning of 1987 but remained close for the rest of the year. Canada's petroleum products exports were made to 5 countries while imports came from at least 13 countries. The USA remained Canada's largest trading partner in petroleum products. Exports to Japan and the Far East rose ca 60% over 1986. Product outturns for export were 9% of total Canadian refinery throughput. Exports of aviation turbine fuel from Ontario began in April 1987. The top single exporter in Canada was Irving Oil Ltd. with 2,485,000 m 3 . Irving was also the top exporter in 1986. 11 figs., 4 tabs

  12. Gas Exports in Turkmenistan

    2011-01-01

    The Caspian region has been at the center of attention since Europe began seeking alternative routes to natural-gas resources. Turkmenistan has the potential to become an important gas exporter to Europe. As a landlocked country, Turkmenistan until recently has relied on post-Soviet pipeline infrastructures. The Central Asian republic has been at the mercy of Moscow's energy policy, which overlaps its foreign policy. At the same time, the revenue from gas exports is an essential part of the Turkmen national budget. This prompted Ashgabat to look for energy partners bypassing Russian territories. It started to convey natural gas first to Iran and then to China. This gave Turkmenistan strong leverage vis-a-vis Moscow. Ashgabat has not decided to export every gas molecule eastward, but, in jeopardizing its relations with Moscow, it expects more than empty pledges from Europe. On the other hand, a simple question emerges: Does Europe really need alternative sources? The answer is in the hands of Gazprom and Russian policy-makers

    1982-10-01

    A number of authors have calculated x-ray energies for mammography using, as a criterion, the maximum signal-to-noise ratio (SNR) obtainable per unit dose to the breast or conversely the minimum exposure for constant SNR. The predicted optimum energy increases with increasing breast thickness. Tungsten anode x-ray spectra have been measured with and without various added filter materials to determine how close the resultant spectra can be brought to the predicted optimum energies without reducing the x-ray output to unacceptable levels. The proportion of the total number of x-rays in a measured spectrum lying within a narrow energy band centred on the predicted optimum has been used as an optimum energy index. The effect of various filter materials on the measured x-ray spectra has been investigated both experimentally and theoretically. The resulting spectra have been compared with molybdenum anode, molybdenum filtered x-ray spectra normally used for mammography. It is shown that filters with K-absorption edges close to the predicted optimum energies are the most effective at producing the desired spectral shape. The choices of filter thickness and Vp are also explored in relationship to their effect on the resultant x-ray spectral shape and intensity.

    Highlights: ► Optimum loading scheme for BAEC TRIGA core is out-to-in loading with 10 fuels/cycle starting with 5 for the first reload. ► The discharge burnup ranges from 17% to 24% of U235 per fuel element for full power (3 MW) operation. ► Optimum extension of operating core life is 100 MWD per reload cycle. - Abstract: The TRIGA Mark II research reactor of BAEC (Bangladesh Atomic Energy Commission) has been operating since 1986 without any reshuffling or reloading yet. Optimum fuel burnup strategy has been investigated for the present BAEC TRIGA core, where three out-to-in loading schemes have been inspected in terms of core life extension, burnup economy and safety. In considering different schemes of fuel loading, optimization has been searched by only varying the number of fuels discharged and loaded. A cost function has been defined and evaluated based on the calculated core life and fuel load and discharge. The optimum loading scheme has been identified for the TRIGA core, the outside-to-inside fuel loading with ten fuels for each cycle starting with five fuels for the first reload. The discharge burnup has been found ranging from 17% to 24% of U235 per fuel element and optimum extension of core operating life is 100 MWD for each loading cycle. This study will contribute to the in-core fuel management of TRIGA reactor

    The Soviet Union produces 20% of world energy but since 1988 this is in decline. Awakening consumerism and a sea-change in the structure of foreign trade and internal investment are placing this key industry into unprecedented uncertainty. The difference between success and failure goes beyond the 1988 peak of six million barrels daily of exports in oil equivalent. The article quantifies the key areas of energy uncertainty as equal in volume to total OPEC output and sees the long-term changes of success more than ever dependent on coordinated planning and investment as well as on market reality.

  6. Protein export through the bacterial flagellar type III export pathway.

    Science.gov (United States)

    Minamino, Tohru

    2014-08-01

    For construction of the bacterial flagellum, which is responsible for bacterial motility, the flagellar type III export apparatus utilizes both ATP and proton motive force across the cytoplasmic membrane and exports flagellar proteins from the cytoplasm to the distal end of the nascent structure. The export apparatus consists of a membrane-embedded export gate made of FlhA, FlhB, FliO, FliP, FliQ, and FliR and a water-soluble ATPase ring complex consisting of FliH, FliI, and FliJ. FlgN, FliS, and FliT act as substrate-specific chaperones that do not only protect their cognate substrates from degradation and aggregation in the cytoplasm but also efficiently transfer the substrates to the export apparatus. The ATPase ring complex facilitates the initial entry of the substrates into the narrow pore of the export gate. The export gate by itself is a proton-protein antiporter that uses the two components of proton motive force, the electric potential difference and the proton concentration difference, for different steps of the export process. A specific interaction of FlhA with FliJ located in the center of the ATPase ring complex allows the export gate to efficiently use proton motive force to drive protein export. The ATPase ring complex couples ATP binding and hydrolysis to its assembly-disassembly cycle for rapid and efficient protein export cycle.

  7. Exports of petroleum products, 1988

    International Nuclear Information System (INIS)

    1989-04-01

    A summary is presented of exports of motor gasoline, middle distillate, aviation turbine fuel, heavy fuel oil, and partially processed oil from Canada for the 1988 calendar year. A discussion of petroleum product imports is included in order to put exports in the context of the overall trade. Exports of the above petroleum products averaged 32,000 m 3 /d in 1988, up 44% from 1987 levels. Each product except aviation fuel registered increases in export volumes, which reached the highest total volume of the decade. The main reason for the large increase was the first full year of production from the export-directed refinery at Come By Chance, Newfoundland. Export prices for light petroleum products stayed relatively close to USA spot prices. The heavy fuel oil price was mostly above the USA east coast spot price during 1988. Attractive prices on the USA east coast resulted in a few cargoes of middle distillate and motor gasoline shipped from British Columbia. Petroleum products imports came from 12 countries; Quebec had the largest volume of imports in 1988. The USA remained Canada's largest trading partner in petroleum products. Western exporters view the Far East as an ongoing important market. The top single exporter in Canada was Newfoundland Processing, with 32% of the total export volume. 12 figs., 3 tabs

  8. Russian nuclear industry exports

    International Nuclear Information System (INIS)

    Gorbatchev, A.

    2016-01-01

    Rosatom is the world leader for the export of nuclear technologies. 34 reactors of Russian technology are being built or planned worldwide. Most reactors proposed by Rosatom are third generation VVER-1200 units with an electric power output of 1200 MWe. Although the nuclear island is always built by Rosatom, the remain of the plant can be subcontracted to other enterprises and European companies are sought because they would bring a european quality touch to Russian works. One of the main assets of Rosatom is to propose an integrated offer from supplying nuclear fuel to managing nuclear waste via the turnkey building of nuclear power plants. Another important asset is the financial assistance of the Russian state through state credit or the support from Russian national banks that appears to be a decisive advantage in the international competition to win markets. We have to temper the Russian export perspectives by noting that most projects are set in countries that are prone to instabilities and that the economic crisis affecting Russia has a negative impact on its financial means.

  9. Wind exports markets

    International Nuclear Information System (INIS)

    Moghadam, Brian

    2011-01-01

    This paper presents the situation of wind export markets and the principles of firming, shaping and moving. Firming means the conversion of uncertain second to second output into hourly deliveries. Firming of energy is used to make up the difference between the hourly schedule and actual output. Firming of capacity is setting aside generation to stand behind fluctuations in wind output within the hour. Shaping is to convert uncertain hour-to-hour output throughout the year into predetermined deliveries that meet consumer demand. Moving refers to BC's attempts to bring about the transport of clean energy to California. But there are transmission issues involved because the network lines to California are already fully subscribed. One solution would be for IPPs to purchase services from Powerex, or any other service provider, at opportunity cost. Another element is that the market price for wholesale electricity is lower than in recent years. It is safe to say that there are lots of uncertainties involved in wind exports.

    The author investigates the poverty impacts of informal export barriers like transport costs, cumbersome customs practices, costly regulations, and bribes. He models these informal barriers as export taxes that distort the efficient allocation of resources. In low-income agricultural economies, this distortion lowers wages and household agricultural income, thereby leading to higher pover...

  12. Exports of crude oil, 1988

    International Nuclear Information System (INIS)

    1989-06-01

    Effective June 1, 1985, licensing and charging of oil exports ended. The Board now issues export orders specifying neither volumes nor prices and covering an exportation period of up to 1 year for light crude oil and up to 2 years for heavy crude oil, available on request to both Canadian and foreign companies. The Board has assumed a monitoring role, and export prices and volumes are reported monthly by exporters. This annual report provides a review of the volumes and prices associated with the supply and disposition of Canadian crude oil during 1988. Highlights are given with detailed information on prices, both internationally, in Canada, and the Chicago posted price by light or heavy crude, and on volumes including capacity and disposition in both domestic and export markets. A short description of the import market is included. Comparisons are made with the previous year. Export volumes of light crude oil in 1988 increased by 13% to average 50,200 m 3 /d. Export volumes of heavy crude also increased by ca 13% to 62,600 m 3 /d. 15 figs., 2 tabs

    Hermansky, B.

    1977-01-01

    The flow sheets are presented of refuelling schedules aimed at obtaining deep average fuel burnup with levelling up the output along the reactor radius in large PWR reactors. The zone refuelling is described in which only 1/3 of the fuel element number is replaced. The elements are placed in the outer zone of the core. Also described is the distributed refuelling in which fuel elements with different burnups are evenly spaced. A modified refuelling schedule is shown involving the replacement from the outside to the inside where a uniform radial distribution of thermal output is achieved. Calculation methods are shown of determining the optimum refuelling strategy. Dynamic programming is one of the prospective computer methods. Its general algorithm is indicated. A survey is made of some studies on the optimum refuelling strategy in pressurized water reactors. (J.B.)

  17. Optimum Operational Parameters for Yawed Wind Turbines

    David A. Peters

    2011-01-01

    Full Text Available A set of systematical optimum operational parameters for wind turbines under various wind directions is derived by using combined momentum-energy and blade-element-energy concepts. The derivations are solved numerically by fixing some parameters at practical values. Then, the interactions between the produced power and the influential factors of it are generated in the figures. It is shown that the maximum power produced is strongly affected by the wind direction, the tip speed, the pitch angle of the rotor, and the drag coefficient, which are specifically indicated by figures. It also turns out that the maximum power can take place at two different optimum tip speeds in some cases. The equations derived herein can also be used in the modeling of tethered wind turbines which can keep aloft and deliver energy.

  18. Mexico: Imports or exports?

    International Nuclear Information System (INIS)

    Estrada, J.

    2002-01-01

    This presentation provides an overview of Mexico's energy sector. Proven oil reserves place Mexico in ninth position in the world and fourth largest in natural gas reserves. Energy is one of the most important economic activities of the country, representing 3 per cent of Gross Domestic Product (GDP). Oil exports represent 8.4 per cent of total exports. Approximately 40 per cent of total public investment is earmarked for energy projects. The author discusses energy resources and energy sector limitations. The energy sector plan for the period 2001-2006 is discussed. Its goals are to ensure energy supply, to develop the energy sector, to stimulate participation of Mexican enterprises, to promote renewable energy sources, and to strengthen international energy cooperation. The regulatory framework is being adapted to increase private investment. Some graphs are presented, displaying the primary energy production and primary energy consumption. Energy sector reforms are reviewed, as are electricity and natural gas reforms. The energy sector demand for 2000-2010 and investment requirements are reviewed, as well as fuel consumption for power generation. The author discusses the National Pipeline System (SNG) and the bottlenecks caused by pressure efficiency in the northeast, flow restriction on several pipeline segments, variability of the Petroleos Mexicanos (PEMEX) own use, and pressure drop on central regions. The entire prospect for natural gas in the country is reviewed, along with the Strategic Gas Program (PEG) consisting of 20 projects, including 4 non-associated natural gas, 9 exploration and 7 optimization. A section dealing with multiple service contracts is included in the presentation. The authors conclude by stating that the priority is a national energy policy to address Mexico's energy security requirements, to increase natural gas production while promoting the diversification of imports, and a regulatory framework to be updated in light of current

  19. NEW APPROACHES TO EXPORT COMPETITIVENESS

    Directory of Open Access Journals (Sweden)

    Alina Petronela NEGREA

    2015-04-01

    Full Text Available The economic literature and the political discourse typically look at international competitiveness mainly by the means of export market shares. However, globalisation, production fragmentation and the growing importance of global value chains (GVCs increasingly challenge traditional approaches of export competitiveness and call for a more accurate and disaggregated level of analysis. Due to the growing fragmentation of production, a country exports now include a significant amount of imports of intermediate goods which are part of the export value. In this case, a simple analysis of the evolution of exports can distort the international competitive position of a country. The article suggests a new approach based on the value-added content of international trade measured by means of global value chain analysis.

    By exporting, firms sell in markets whose business cycles are not perfectly correlated, and so can be expected to have more stable cash flows. If companies are liquidity constrained, this stability of cash flows can provide exporters with certain advantages over firms that operate solely in a domestic market. For instance, under the existence of liquidity constraints, more stable cash flows should foster more stable capital investments. Moreover, the expectation of more stable future cash flo...

    1987-01-01

    In developing the policy framework for the export of uranium, successive governments have been keenly aware that, in Australia, as in most countries, there has been considerable community interest and controversy surrounding the subject of uranium. When the Australian Labor Government was elected in 1983, it commissioned the Australian Science and Technology Council (ASTEC) to report on Australia's role in the nuclear fuel cycle. In particular, the report examined: (i) Australia's nuclear safeguards arrangements, giving particular attention to the effectiveness of the bilateral and multilateral agreements and to the scope for strengthening these agreements, (ii) the opportunities for Australia through the conditions of its involvement in the nuclear fuel cycle to further advance the cause of nuclear non-proliferation having regard to the policies and practices of recipient countries, (iii) the adequacy of existing technology for the handling and disposal of waste products by consuming countries, and the ways in which Australia could further contribute to the development of safe disposal methods.

    A overview of the Export Administration Act of 1979 and subsequent regulations and amendments focuses on how licensing requirements and restrictions against boycott affect high technology exports. The purpose of these controls is to limit the export of technology with possible military applications, as well as to advance US foreign policy and protect the economy without imposing too great a restriction on the principles of free trade. Thus, the act encompasses political, economic, and security goals. Problems of predictability arise when embargoes or other controls are imposed for political or foreign policy reasons without regard to economic impacts. Amendments have attempted to streamline the exporting process, particularly in the area of computer and software licensing.

  13. Optimum body size of Holstein replacement heifers.

    Science.gov (United States)

    Hoffman, P C

    1997-03-01

    Criteria that define optimum body size of replacement heifers are required by commercial dairy producers to evaluate replacement heifer management programs. Historically recommended body size criteria have been based on live BW measurements. Numerous research studies have observed a positive relationship between BW at first calving and first lactation milk yield, which has served as the impetus for using live BW to define body size of replacement heifers. Live BW is, however, not the only available measurement to define body size. Skeletal measurements such as wither height, length, and pelvic area have been demonstrated to be related to first lactation performance and (or) dystocia. Live BW measurements also do not define differences in body composition. Differences in body composition of replacement heifers at first calving are also related to key performance variables. An updated research data base is available for the modern Holstein genotype to incorporate measures of skeletal growth and body composition with BW when defining body size. These research projects also lend insight into the relative importance of measurements that define body size of replacement heifers. Incorporation of these measurements from current research into present BW recommendations should aid commercial dairy producers to better define replacement heifer growth and management practices. This article proposes enhancements in defining optimum body size and growth characteristics of Holstein replacement heifers.

    Full Text Available Communication aims to discuss the new scientific vision of "the entire integrated" as it follows the recent achievements of quantum physics, psychology and biology. From this perspective, economy is seen as a living organism, part of the social organism and together with de bright ecology. The optimum of the economy as a living organism is based on dynamic compatibilities with all common living requirements. The evolution of economic life is organically linked to the unavoidable circumstances contained in the form of V. Frankl ‘s tragic triad consisting of: pain, guilt and death. In interaction with the holistic triad circumscribed by limitations, uncertainties and open interdependencies, the tragic economic optimum (TEO is formed. It can be understood as that state of economic life in which freedom of choice of scarce resources under uncertainty has in the compatibility of rationality and hope the development criteria of MEANING. TEO means to say YES to economic life even in conditions of resource limitations, bankruptcies and unemployment, negative externalities, stress, etc. By respiritualization of responsibility using scientific knowledge. TEO - involves multicriteria modeling of economic life by integrating human demands, community, environmental, spiritual and business development in the assessment predicting human GDP as a variable wave aggregate.

    Full Text Available The present work deals with the Brazilian exports of sawnwood of non-coniferous, veneer sheets and plywood, from 1961 to 2002. The data regarding the three studied products, sawnwood of non-coniferous, veneer sheets and plywood, were joined through the method of Fisher so that an econometric evaluation of the market of the three products could be carried out. Supply and demand models of the Brazilian exports were specified. The results were satisfactory and they match with the literature. The supply of exports presented a positive answer in relation to the exporter's remuneration, to the production, to the use of the installed capacity (cycles of domestic economical activity and to the tendency, and negative in relation to the internal demand. The demand for the Brazilian exports was influenced positively by the world income, participation index and tendency, and negatively for the relative price. The low elasticity-price of the found demand can have implications in the conservation of the Brazilian forest resources because the exporters can increase the prices, reduce the amounts and still increase the incomes.

  17. Exports of petroleum products, 1990

    International Nuclear Information System (INIS)

    1991-04-01

    A summary is presented of exports of motor gasoline, middle distillate, aviation turbine fuel, heavy fuel oil, and partially processed oil from Canada for the 1990 calendar year. Exports of the above petroleum products averaged 34,000 m 3 /d in 1990, up 12% from 1989 levels. The increase reflects increased output from the Come By Chance refinery in Newfoundland. Motor gasoline exports increased 35% to 10,500 m 3 /d, reflecting refinery upgrading in eastern Canada. Export prices were generally in line with spot product prices in the USA. Spot prices rose sharply following the Kuwait crisis in August 1990 but fell again in November. The spot price for jet fuel rose more dramatically in that period than for other products, reflecting increased military demand. In winter 1989/90 and during the Kuwait conflict, the export price of heating oil tended to track the USA spot price. Petroleum products imports in 1990 were 18,500 m 3 /d, compared to 21,900 m 3 /d in 1988. Imports were lower partially as a result of higher crude runs in Quebec and a Quebec refinery expansion. Imports of heavy fuel oil in eastern Canada continued to be strong in comparison to the mid-1980s. The top single exporter in 1990, as in 1989, was Newfoundland Processing, with a volume of 4,506,400 m 3 . 13 figs., 5 tabs

    A summary is presented of exports of motor gasoline, middle distillate, aviation turbine fuel, heavy fuel oil, and partially processed oil from Canada for the 1989 calendar year. A discussion of petroleum product imports is included in order to put exports in the context of the overall trade. Exports of the above petroleum products averaged 30,400 m 3 /d in 1989, down 5% from 1988 levels. Motor gasoline shipments showed the largest decrease, down 1,500 m 3 to 7,700 m 3 /d. Export prices for light petroleum products stayed relatively close to USA spot prices except in June and July 1989, when attractive prices were obtained for shipments from the prairie provinces. The heavy fuel oil export price was similar to the USA east coast spot price in 1989, except in December. Canada's petroleum products imports in 1989 were 21,600 m 3 /d, compared to 18,400 m 3 /d in 1988. Imports of heavy fuel oil in eastern Canada rose 36% in 1989 because of industries switching from electricity and the high demand for thermal power generation. The USA remained Canada's largest trading partner in petroleum products. The top single exporter in 1989, as in 1988, was Newfoundland Processing, with a volume of 3,484,500 m 3 . 24 figs., 4 tabs

  19. Australia's uranium export potential

    International Nuclear Information System (INIS)

    Mosher, D.V.

    1981-01-01

    During the period 1954-71 in Australia approximately 9000 MT of U 3 O 8 was produced from five separate localities. Of this, 7000 MT was exported to the United Kingdom and United States and the balance stockpiled by the Australian Atomic Energy Commission (AAEC). Australia's uranium ore reserves occur in eight deposits in three states and the Northern Territory. However, 83% of Australia's reserves are contained in four deposits in lower Proterozoic rocks in the East Alligator River region of the Northern Territory. The AAEC has calculated Australia's recoverable uranium reserves by eliminating estimated losses during the mining and milling of the ores. AAEC has estimated reasonably assured resources of 289,000 MT of uranium at a recovery cost of less than US$80 per kilogram uranium. The companies have collectively announced a larger ore reserve than the Australian Atomic Energy Commission. This difference is a result of the companies adopting different ore reserve categories. On August 25, 1977, the federal government announced that Australia would develop its uranium resources subject to stringent environmental controls, recognition of Aboriginal Land Rights, and international safeguards. Australian uranium production should gradually increase from 1981 onward, growing to 10,000 to 15,000 MT by 1985-86. Further increases in capacity may emerge during the second half of the 1980s when expansion plans are implemented. Exploration for uranium has not been intensive due to delays in developing the existing deposits. It is likely that present reserves can be substantially upgraded if more exploration is carried out. 6 figures, 3 tables

    2006-01-01

    This paper investigates whether exporting generates positive productivity spillover effects on other plants operating in the same industry and whether exporting affects productivity of plants in vertically related industries. Using plant-level data from Chile we find that exporters improve productivity of their local suppliers but not of plants that purchase intermediate inputs from them. We also find evidence of horizontal spillovers from exporting. Exporting by foreign-owned plants generate...

    1997-01-01

    One of the major criticisms of government export promotion schemes in many countries is that they tend to be poorly targeted. Awareness levels about export schemes among managers of companies at exporting or pre-exporting stages of internationalization are often quite low, and the perceived usefulness of schemes may decline as companies internationalize and their needs become more specific. One solution may be to develop a better understanding of the needs of managers who make export market d...

    Borel, J.P.

    1984-01-01

    This paper presents an economic analysis for the optimum design of a nuclear heat supply to a given district-heating network. First, a general description of the system is given, which includes a nuclear power plant, a heating power plant and a district-heating network. The heating power plant is fed with steam from the nuclear power plant. It is assumed that the heating network is already in operation and that the nuclear power plant was previously designed to supply electricity. Second, a technical definition of the heat production and transportation installations is given. The optimal power of these installations is examined. The main result is a relationship between the network capacity and the level of the nuclear heat supply as a substitute for oil under the best economic conditions. The analysis also presents information for choosing the best operating mode. Finally, the heating power plant is studied in more detail from the energy, technical and economic aspects. (author)

  12. Optimum Maintenance Strategies for Highway Bridges

    Frangopol, Dan M.; Thoft-Christensen, Palle; Das, Parag C.

    As bridges become older and maintenance costs become higher, transportation agencies are facing challenges related to implementation of optimal bridge management programs based on life cycle cost considerations. A reliability-based approach is necessary to find optimal solutions based on minimum...... expected life-cycle costs or maximum life-cycle benefits. This is because many maintenance activities can be associated with significant costs, but their effects on bridge safety can be minor. In this paper, the program of an investigation on optimum maintenance strategies for different bridge types...... is described. The end result of this investigation will be a general reliability-based framework to be used by the UK Highways Agency in order to plan optimal strategies for the maintenance of its bridge network so as to optimize whole-life costs....

    2011-01-01

    Full Text Available In this study, the basic engineering principles, goals, and constraints are all combined to fuzzy methodology and applied to design of optimally pressurised containers emphasising the ecological and durability merits of various materials. The present fuzzy heuristics approach is derivable from generalisation of conventional analytical optimisation method into fuzzy multitechnical tasks. In the present approach, first the goals and constraints of the end-user are identified. Then decision variables are expressed as functions of the design variables. Their desirable ranges and biases are defined using the same fuzzy satisfaction function form. The optimal result has highest total satisfaction. These are then checked and fine-tuned by finite element method FEM. The optimal solution is the ecoplastic vessel, and aluminium was close. The method reveals that optimum depends strongly on the preset goals and values of the producer, society, and end-user.

    2015-06-01

    Full Text Available Formation sand control is always one of the main concerns of production engineers. There are some different methods to prevent sand production. Choosing a method for preventing formation sand production depends on different reservoir parameters and politic and economic conditions. Sometimes, economic and politic conditions are more effective to choose an optimum than reservoir parameters. Often, simultaneous investigation of politic and economic conditions with reservoir parameters has different results with what is expected. So, choosing the best sand control method is the result of thorough study. Global oil price, duration of sand control project and costs of necessary equipment for each method as economic and politic conditions and well productivity index as reservoir parameter are the main parameters studied in this paper.

  15. Global export thermal coal supply : an overview

    International Nuclear Information System (INIS)

    Rusz, D.

    2010-01-01

    The presentation discussed the outlook for global thermal coal exports for the next decade. Seaborne thermal exports are projected to grow 50 percent within ten years. Indonesia and Australia will continue to dominate seaborne thermal production, and the United States and China will remain swing global thermal suppliers. In 2020, Indonesia and Australia will occupy a strengthened position as the main exporters of thermal coal. Mid-suppliers Russia, South Africa, and Colombia will increase production, but to a lesser extent. Domestic coal requirements will cause Vietnam's exports to decrease substantially. Indonesia, the largest thermal exporter, is expected to grow thermal exports by 54 percent by 2020, but the average quality is projected to decrease. The thermal exports of Australia, the second largest exporter, are projected to grow 90 percent by 2020. Latin American thermal exports are projected to grow 45 percent. For Southern Africa, thermal exports are projected to grow 40 percent by 2020, but domestic production is expected to be twice that of exports. Mozambique is expected to begin exporting in 2015. A cost overview was also presented for seaborne thermal coal exports. Low cost producers dominate the export market. Canada's operating margins are low relative to the world. Asian-Pacific producers will continue to lead and expand their production dominance in the thermal trade. Operating margins for thermal export producers are healthy in general. 14 figs.

  16. China's coal export and inspection

    1993-01-01

    With the development of world's business and trade, coal has become a large part of the import and export goods in the international market. The total amount of coal trade has risen a lot. China is rich in coal resources. According to the estimate made by some experts, the reserve which has been explored recently could be exploited hundreds of years. China's output of raw coal has risen a lot during the past forty years. China coal industry has developed rapidly since the 1980s. It is possible for China to become a big coal export country since it has rich resources and increasing output. The paper suggests four steps which must be taken to expand coal exports in China: improve the level of management and administration of coal mines so as to raise the economic benefit; the follow-up production capacity of the present mines must be enhanced rapidly; step up construction of new large-scale mines; and China's coal washing capacity must be improved speedily since the low capacity has seriously influenced the improvement of coal quality. The paper describes the inspection bureaus and companies that have developed to perform inspection of exports in order to guarantee the quality of export coal

    2016-09-01

    Full Text Available Background: In the area of exporting, in developing countries, including Iran, the concept of export readiness is unknown to many decision makers and field of activity of Iranian pharmaceutical companies have been limited to the domestic market. Therefore, the main objective of this study is to compare the export performance of ten Iranian pharmaceutical companies with their export readiness. Methods: In order to do this, the top ten of Iranian pharmaceutical companies were selected as the sample. The companies' export readiness was measured, and compared with their export volume as well as their export growth (as two factors for determining the export performance in five years, to practically check the model and find the strengths and weaknesses of these Iranian pharmaceutical companies in the export factors. Results: Base on the results of the study, the export readiness of these companies does not have significant correlation with companies' export volume in the current circumstances, but it can predict the export growth in the firm's export rate with 95% certainty. Conclusion: The most important thing is that according to the data collected in our study, most of these ten Iranian pharmaceutical companies are not ready to attend in exporting and international markets and only two companies were ready to export. It seems that making improvement in some variables like obtaining international standards, marketing and exporting education, having a transparent and documented plan and having the responsible person for export could increase export readiness of pharmaceutical companies.

    2013-07-01

    Full Text Available Electric power theft is a problem that continues to plague power sector across the whole country. Every year, the electricity companies face the line losses at an average 20-30% and according to power ministry estimation WAPDA companies lose more than Rs. 125 billion. Significantly, it is enough to destroy the entire power sector of country. According to sources 20% losses means the masses would have to pay extra 20% in terms of electricity tariffs. In other words, the innocent consumers pay the bills of those who steal electricity. For all that, no any permanent solution for this major issue has ever been proposed. We propose an applicable and optimum solution for this impassable problem. In our research, we propose an Electric power theft solution based on three stages; Transmission stage, Distribution stage, and User stage. Without synchronization among all, the complete solution can not be achieved. The proposed solution is simulated on NI (National Instruments Circuit Design Suite Multisim v.10.0. Our research work is an implicit and a workable approach towards the Electric power theft, as for conditions in Pakistan, which is bearing the brunt of power crises already

    2015-07-01

    Full Text Available Abstract In liver scintigraphy radioactive tracers in addition to liver are accumulated in other organs such as spleen. It leads to the presence of secondary source which affects image quality. Therefore knowing the influence of the noise arising from the secondary source and trying to reduce the additional data is necessary. In nuclear medicine imaging using of energy window is a useful way to reduce the noise. In this paper we try to find an optimum energy window to reduce the noise for two different low energy collimators. Liver scintigraphy images with and without activity in spleen were simulated by SIMIND software with different energy window percentages and with Low-Energy High-Resolution LEHR and Low-Energy General-Purpose LEGP collimators. We used with activity of 190 MBq. Spleen was outside of the camera field of view so that just its noise effects on the liver image is examined. Finally the images of liver with activity in spleen were compared with that without activity in spleen by MATLAB code.

  7. Optimum harvest maturity for Leymus chinensis seed

    2016-06-01

    Full Text Available Timely harvest is critical to achieve maximum seed viability and vigour in agricultural production. However, little information exists concerning how to reap the best quality seeds of Leymus chinensis, which is the dominant and most promising grass species in the Songnen Grassland of Northern China. The objective of this study was to investigate and evaluate possible quality indices of the seeds at different days after peak anthesis. Seed quality at different development stages was assessed by the colours of the seed and lemmas, seed weight, moisture content, electrical conductivity of seed leachate and germination indices. Two consecutive years of experimental results showed that the maximum seed quality was recorded at 39 days after peak anthesis. At this date, the colours of the seed and lemmas reached heavy brown and yellow, respectively. The seed weight was highest and the moisture content and the electrical conductivity of seed leachate were lowest. In addition, the seed also reached its maximum germination percentage and energy at this stage, determined using a standard germination test (SGT and accelerated ageing test (AAT. Thus, Leymus chinensis can be harvested at 39 days after peak anthesis based on the changes in parameters. Colour identification can be used as an additional indicator to provide a more rapid and reliable measure of optimum seed maturity; approximately 10 days after the colour of the lemmas reached yellow and the colour of the seed reached heavy brown, the seed of this species was suitable for harvest.

  9. RNA Export through the NPC in Eukaryotes.

    Science.gov (United States)

    Okamura, Masumi; Inose, Haruko; Masuda, Seiji

    2015-03-20

    In eukaryotic cells, RNAs are transcribed in the nucleus and exported to the cytoplasm through the nuclear pore complex. The RNA molecules that are exported from the nucleus into the cytoplasm include messenger RNAs (mRNAs), ribosomal RNAs (rRNAs), transfer RNAs (tRNAs), small nuclear RNAs (snRNAs), micro RNAs (miRNAs), and viral mRNAs. Each RNA is transported by a specific nuclear export receptor. It is believed that most of the mRNAs are exported by Nxf1 (Mex67 in yeast), whereas rRNAs, snRNAs, and a certain subset of mRNAs are exported in a Crm1/Xpo1-dependent manner. tRNAs and miRNAs are exported by Xpot and Xpo5. However, multiple export receptors are involved in the export of some RNAs, such as 60S ribosomal subunit. In addition to these export receptors, some adapter proteins are required to export RNAs. The RNA export system of eukaryotic cells is also used by several types of RNA virus that depend on the machineries of the host cell in the nucleus for replication of their genome, therefore this review describes the RNA export system of two representative viruses. We also discuss the NPC anchoring-dependent mRNA export factors that directly recruit specific genes to the NPC.

    Directory of Open Access Journals (Sweden)

    Jun Katahira

    2015-03-01

    Full Text Available Transport of messenger RNA (mRNA from the nucleus to the cytoplasm is an essential step of eukaryotic gene expression. In the cell nucleus, a precursor mRNA undergoes a series of processing steps, including capping at the 5' ends, splicing and cleavage/polyadenylation at the 3' ends. During this process, the mRNA associates with a wide variety of proteins, forming a messenger ribonucleoprotein (mRNP particle. Association with factors involved in nuclear export also occurs during transcription and processing, and thus nuclear export is fully integrated into mRNA maturation. The coupling between mRNA maturation and nuclear export is an important mechanism for providing only fully functional and competent mRNA to the cytoplasmic translational machinery, thereby ensuring accuracy and swiftness of gene expression. This review describes the molecular mechanism of nuclear mRNA export mediated by the principal transport factors, including Tap-p15 and the TREX complex.

    Under the 10th Malaysian Plan, the government is expecting the renewable energy to contribute approximately 5.5% to the total electricity generation by the year 2015, which amounts to 98MW. One of the initiatives to ensure that the target is achievable was to establish the Sustainable Energy Development Authority of Malaysia. SEDA is given the authority to administer and manage the implementation of the feed-in tariff (FiT) mechanism which is mandated under the Renewable Energy Act 2011. The move to establish SEDA is commendable and the FiT seems to be attractive but there is a need to create awareness on the implementation of the solar electricity generating system (SEGS). In Malaysia, harnessing technologies related to solar energy resources have great potential for implementation. However, the main issue that plagues the implementation of SEGS is the intermittent nature of this source of energy. The availability of sunlight is during the day time, and there is a need for electrical energy storage system, so that there is electricity available during the night time as well. The meteorological condition such as clouds, haze and pollution affects the SEGS as well. The PV based SEGS is seems to be promising electricity generating system that can contribute towards achieving the 5.5% target and will be able to minimize the negative effects of utilizing fossil fuels for electricity generation on the environment. Malaysia is committed to Kyoto Protocol, which emphasizes on fighting global warming by achieving stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system. In this paper, the technical aspects of the implementation of optimum SEGS is discussed, especially pertaining to the positioning of the PV panels.

    1980-01-01

    Economic policy in four oil-producing countries is analyzed within a framework that combines a qualitative assessment of the policy-making process with an empirical formulation based on historical and current trends in these countries. The concept of absorptive capacity is used to analyze the optimum rates of petroleum production in Iran, Iraq, Saudi Arabia, and Kuwait. A control solution with an econometric model is developed which is then modified for alternative development strategies based on analysis of factors influencing production decisions. The study shows the consistencies and inconsistencies between the goals of economic growth, oil production, and exports, and the constraints on economic development. Simulation experiments incorporated a number of the constraints on absorptive capacity. Impact of other constraints such as income distribution and political stability is considered qualitatively.

    2012-05-01

    Full Text Available The present paper investigates the relationship between Competitive Intelligence (CI factors, characteristics, information sources, needs, requirements and the export intensity of exporting companies in South Africa. We establish whether there are significant differences between firms, grouped according to export intensity with respect to awareness, use, information sources and attitude towards CI activities. A questionnaire was developed and sent to exporting firms, resulting in a usable sample of 309 South African respondents. These firms are grouped according to export intensity, and CI practices between groups are compared. The results show that export intensive firms appear to be more aware and supportive of CI activities than less export intensive firms.

  7. The Chinese Export Displacement Effect Revisited

    DEFF Research Database (Denmark)

    Elleby, Christian; Yu, Wusheng; Yu, Qian

    China’s global export share has increased dramatically over the past decades. This development has prompted an empirical literature on whether Chinese exports displace those originated from elsewhere in various destination markets. In this paper we focus on the growth of China’s exports to the East...... African Community (EAC) countries and show how it has affected exports from the European Union (EU) to the EAC. Our main contribution to the literature on the displacement effect of Chinese exports is a set of total and relative displacement estimates based on different specifications of the gravity model...... where we control for country-year fixed effects so as to avoid the “gold medal mistake” of not accounting for time varying “multilateral resistance”. Our findings do not support the hypothesis that Chinese exports have displaced exports from other countries in general. Nor do they support the hypothesis...

  8. NAS Panel faults export controls

    Science.gov (United States)

    Katzoff, Judith A.

    A study prepared by a top-level panel says that current export controls on militarily sensitive U.S. technology may be “overcorrecting” previous weaknesses in that system, resulting in “a complex and confusing control system” that makes it more difficult for U.S. businesses to compete in international markets. Moreover, this control system has “an increasingly corrosive effect” on U.S. relations with allies. The panel recommended that the United States concentrate more effort on bringing about uniformity in the export control policies of countries belonging to the Coordinating Committee on Multilateral Export Controls (CoCom), i.e., most of the member nations in NATO (the North Atlantic Treaty Organization) and Japan.The 21-member panel was appointed by the Committee on Science, Engineering, and Public Policy (COSEPUP), a joint unit of the National Academy of Sciences (NAS), the National Academy of Engineering (NAE), and the Institute of Medicine (IOM). The panel, composed of administrators, researchers, and former government officials, was chaired by AGU member Lew Allen, Jr., director of the Jet Propulsion Laboratory (Pasadena, Calif.) and former chief of staff of the U.S. Air Force. Their report was supported by NAS funds, by a number of private organizations (including AGU), by the U.S. Departments of Commerce, Defense, Energy, and State, by the National Science Foundation, and by the National Aeronautics and Space Administration.

  9. Optimum operation cycle of nuclear plant in power system operation

    International Nuclear Information System (INIS)

    Kurihara, Ikuo; Matsumura, Tetsuo; Katayama, Noboru

    1989-01-01

    Extension of nuclear power plant operation cycle leads to improvement of its capacity factor and affects to suppress thermal plant generation of which fuel cost is relatively high. On the other hand, the number of nuclear fuel assembly to be exchanged at the time of maintenance increases with the operation cycle extension and this makes the fuel cost of nuclear generation high. For this reason, there exists the optimum operation cycle from the power system operation. This report deals with the optimum operation cycle of nuclear plant as the optimum sharing problem of generated energy between nuclear and thermal plants. The incremental fuel cost is considered to find the optimum value. The effects of the generation mix and high burn-up fuel on optimum operation cycle are examined. (author)

  10. Perceived impediments to export involvement among small and medium sized firms : non-exporters perspective

    Directory of Open Access Journals (Sweden)

    Mercy Mpinganjira

    2011-12-01

    Full Text Available Purpose: The main purpose of this paper is to examine perceived impediments to export involvement among non-exporting small and medium sized firms (SME's in Malawi. The study also examines levels of interest in exporting among the firms. Problem investigated: Many countries have programs aimed at promoting export involvement among SME's. Despite this, most SME's continue to ignore exporting as a viable business strategy. Information on perceived impediments to export involvement especially from the non-exporters' perspective is often lacking hence the need for this study. Methodology: Data was collected from 80 owner managers of non-exporting SME's. A structured questionnaire was the main instrument used to collect data. Personal interviews were also held with managers for the purposes of probing their answers to the questions in the questionnaire. Statistical Package for Social Science (SPSS version 18 was used to analyse the quantitative data obtained from use of the structured questionnaire. Qualitative data obtained through personal interviews was analysed used thematic analysis. Findings: The findings of the study showed significant levels of interest in exporting among the firms. The majority of the owner managers indicated willingness to exploit export opportunities that may be readily available to them. The findings however showed that just over half of the respondents had discussed or investigated the possibility of exporting before. On impediments to exporting, the findings showed that managers perceive many factors as important impediments to their firm's involvement in exporting. The top two most important impediments were internal to the firm and related to human resource issues. They included insufficient knowledge about export opportunities and lack of personnel knowledgeable in exporting. Originality and value of the research: A review of literature shows that most export promotion studies tend to focus more on issues relating to

  11. Nuclear export controls - Closing the gaps

    International Nuclear Information System (INIS)

    Schmidt, Fritz W.

    2005-01-01

    Concerns over a nuclear 'black market' have focused international attention on the effectiveness of nuclear export controls. IAEA Director General Mohamed ElBaradei has stated that the emergence of a multinational illicit network demonstrated the inadequacy of the present export control system, that international cooperation on export controls lay on informal arrangements that were not only not binding but also limited in membership, and that export control information was not systematically shared with the IAEA. This criticism, often heard on the political level, does not really do justice to the work of export control groups. The emergence of a multinational illicit network does not necessarily prove failures in export control systems. Criminal activities, by definition, try to circumvent existing rules and regulations, or they exploit the absence of such rules on State level. To fight such individual cases is not so much a task of regular export control systems, whose function lies primarily in establishing standards and procedures for export controls on State level, but rather the task for intelligence services and their international cooperation. The basis of the export control regime is the Nuclear Non-Proliferation Treaty (NPT). Export controls can - and do - play an important role in fostering this universality goal by demanding the implementation of internationally agreed security standards in recipient countries before export licenses are granted. Drawn from the deliberations in the NPT conferences, the current standards to be demanded as conditions of supply are the following: Safeguards, Physical Protection, National export control provisions. According to the NPT system, export controls require IAEA verification in the recipient country. In addition, export controls enable States to provide information to the IAEA on exports and imports as required by the Additional Protocol. The 2005 NPT Review Conference will be an opportunity to review developments

  12. Understanding China's renewable energy technology exports

    International Nuclear Information System (INIS)

    Liu, Jialu; Goldstein, Don

    2013-01-01

    China became a major player in renewable energy (RE) technology during the 2000s. Chinese solar PV cell and module makers quickly dominated global sales in that industry, while the country's wind turbine producers became poised for significant exports after capturing their rapidly growing home market. In countries like the US, Chinese RE technology strength has been met with claims of excessive governmental support of exports. This study examines to what extent Chinese firms' solar PV and wind technology successes have been enabled by policy supports, and whether those policies appear to have been driven by broader goals versus RE export promotion per se. The evidence suggests that governmental policy toward both wind and solar originated in a push for export-competitive Chinese companies. But the specifics differed substantially due to the particular requirements of building technological capabilities in each: export readiness necessitated substantial support for domestic installation of wind but not solar PV power. The findings also suggest that as the decade of the 2000s progressed, environmental goals played an increasing role alongside export promotion in motivating and shaping Chinese RE technology policies. - Highlights: ► Export policy in the rise of Chinese renewable energy technologies is studied. ► Policy supported wind turbine firms' capabilities via domestic uptake, not exports. ► Pre-2009 solar module exports enjoyed, but did not depend on, export subsidies. ► Renewables development also fit wider technology and environmental policy goals.

  13. The optimum design of power distribution for pressurized water reactor

    International Nuclear Information System (INIS)

    Dai, Chunhui; Wei, Xinyu; Tai, Yun; Zhao, Fuyu

    2012-01-01

    Highlights: ► A two-level optimization method is developed. ► LP is optimized by backward diffusion calculation theory. ► Pontryagin’s maximum principle is used to investigate the optimum BP arrangement. ► NSGA-II is applied to coordinate the interrelationship between LP and BP. ► The optimized core saves fuel while providing a large power. -- Abstract: The aim of this work is to develop a two-level optimization method for designing the optimum initial fuel loading pattern and burnable poison placement in pressurized water reactors. At the lower level, based on the fuel loading pattern (LP) optimized by backward diffusion calculation theory, Pontryagin’s maximum principle is employed to investigate the optimum arrangement of burnable poison (BP) that can generate the lowest radial power peaking factor (PPF). At the upper level a multi-objective problem (MOP), with LP and BP as two objective functions, is proposed by coordinate the interrelationship of LP and BP, and optimized by non-dominated sorting genetic algorithm (NSGA-II). The results of optimum designs called ‘Pareto optimum solutions’ are a set of multiple optimum solutions. After sensitivity analysis is performed, the final optimum solution which is chosen based on a typical VVER-1000 reactor reveals that the method could not only save the fuel consumption but also reduce the PPF in comparison to published data.

    Nigdeli, Sinan Melih; Bekdaş, Gebrail

    2012-09-01

    In this study the optimum parameters of tuned mass dampers (TMD) are investigated under earthquake excitations. An optimization strategy was carried out by using the Harmony Search (HS) algorithm. HS is a metaheuristic method which is inspired from the nature of musical performances. In addition to the HS algorithm, the results of the optimization objective are compared with the results of the other documented method and the corresponding results are eliminated. In that case, the best optimum results are obtained. During the optimization, the optimum TMD parameters were searched for single degree of freedom (SDOF) structure models with different periods. The optimization was done for different earthquakes separately and the results were compared.

    This paper examines the exporting behaviour of Russian manufacturers by considering the effects of firm characteristics and external conditions. Two measures of export behaviour are considered: the decision to export and the share of exports to developed markets. I find that specific exporting experience is the main determinant of both export status and destination. Contrary to studies for other countries, firm features, with the exception of firm size, are irrelevant for export status, while...

    Based on New Brunswick Power's energy export experience over the past two decades, it appears that Canada could have a very special and unique opportunity to input into the US energy market over the coming decades. The CANDU reactor can offer one of these opportunities. Such business opportunities can be of very real benefit to both countries and to the particular regions involved. Like any other form of business, this one must be carefully planned and must be conducted in an environment conducive to the achievement of the objectives of the business

  19. The Plasmodium export element revisited.

    Directory of Open Access Journals (Sweden)

    Jan Alexander Hiss

    Full Text Available We performed a bioinformatical analysis of protein export elements (PEXEL in the putative proteome of the malaria parasite Plasmodium falciparum. A protein family-specific conservation of physicochemical residue profiles was found for PEXEL-flanking sequence regions. We demonstrate that the family members can be clustered based on the flanking regions only and display characteristic hydrophobicity patterns. This raises the possibility that the flanking regions may contain additional information for a family-specific role of PEXEL. We further show that signal peptide cleavage results in a positional alignment of PEXEL from both proteins with, and without, a signal peptide.

  1. Price and Income Elasticities of Russian Exports

    Directory of Open Access Journals (Sweden)

    Bernardina Algieri

    2004-12-01

    Full Text Available The paper gauges export demand elasticities for Russia using an Error Correction technique within a cointegration framework. An extended version of the Imperfect Substitutes Model has been implemented to estimate the sensitivity of Russian exports without oil components to price and to Russian and world income. Our results suggest a robust and negative long run cointegration relationship between the real effective exchange rate, defined as the weighted average of the rouble’s exchange rates versus a basket of the three currencies with the largest share in the trade turnover adjusted to incorporate inflation rate differences (the ratio of the domestic price indices to the foreign price indices, and Russian exports. An increase in exports by 24% is caused by a real depreciation by 10%. Furthermore, a 10% growth in world income leads to a 33% rise in exports. Finally, exports drop by 14% whenever a 10% increase in domestic income occurs

    We derive an estimating equation to estimate markups using the insight of Hall (1986) and the control function approach of Olley and Pakes (1996). We rely on our method to explore the relationship between markups and export behavior using plant-level data. We find significantly higher markups when...... we control for unobserved productivity shocks. Furthermore, we find significant higher markups for exporting firms and present new evidence on markup-export status dynamics. More specifically, we find that firms' markups significantly increase (decrease) after entering (exiting) export markets. We...... see these results as a first step in opening up the productivity-export black box, and provide a potential explanation for the big measured productivity premia for firms entering export markets....

    1983-01-01

    The problem of optimum long-term development of the nuclear energy system is considered. The optimum strategies (i.e. minimum total uranium consumption) for the transition phase leading to a stationary regime of development are found. For this purpose the author has elaborated a new method of solving linear problems of optimal control which can include jumps in trajectories. The method gives a possibility to fulfil a total synthesis of optimum strategies. A key characteristic of the problem is the productivity function of the nuclear energy system which connects technological system parameters with its growth rate. There are only two types of optimum strategies, according to an increasing or decreasing productivity function. Both cases are illustrated with numerical examples. (orig.) [de

  17. Export Margins, Price and Quantity of Belarus’s Export Growth

    Directory of Open Access Journals (Sweden)

    Otamurodov Shavkat

    2017-03-01

    Full Text Available This paper examines the sources of Belarus’s export growth and decomposes export growth into extensive and intensive margins. This study also aims to determine export margins for intermediate and final goods and to determine the price and quantity components of the intensive export margin. In order to achieve the desired objectives, we use two methods for decomposing export growth, the count method and the export shares method. We analyse Belarus's export growth using export data at the HS-6 digit level for the 2004-2014 period. Our results show that Belarus's exports grew mainly due to growth in the price margin during the studied period 2004-2014. However, the extensive margin was important in export growth to some extent. Comparing the growth rate across final and intermediate goods reveals that although the share of final products in Belarus’s exports is not very big (18.9% in 2014, the average annual growth in exports of final products is higher than that of intermediate goods. Our investigation also shows that Belarus produces a wide range of commodities, but the share of the most of these commodities is not large; its exports depend on a restricted range of commodities. Moreover, most of the commodities are exported to Russia and Ukraine. Our results give us reason to assume that finding new markets for their new products is one of the main challenges for developing countries wishing to increase their exports by an extensive margin. This has important implications for how policy makers promote the trade and diversification of exports.

  8. Scheme to reward microgenerators exporting excess electricity

    International Nuclear Information System (INIS)

    2007-01-01

    Many suppliers are offering tariffs for export. However, many of the tariffs on offer deliver a value that is higher than the underlying commercial value of the electricity to the supplier. In most cases suppliers do not currently register the export within the industry's settlement arrangements and so gain no value from the export they have purchased. It is clear from this that the current situation is unlikely to be sustainable and suppliers will not be able to offer significant payment for a product that has little commercial value to them when the numbers of exporting microgenerators increases. Initiatives to simplify and streamline the existing trading arrangements should be progressed; this should include simplification of processes for registering new export customers and improvements in the provision of new export meters. Suppliers should initiate the change management procedures required to progress Option 1 (allowing suppliers to register a customer's export and import under a single registration (a single MPAN)) through the industry's normal change management procedures. Ofgem should ensure that its review of the Structure of Distribution charges includes the treatment of DUoS charges for customers with microgeneration and ensure that they properly reflect the benefits of microgeneration. Any changes that are progressed should not prevent the subsequent introduction of 'smart meters' that could process both import and export electricity data. Ofgem should ensure that the cost effectiveness of including both an import and export capability in all new metering systems is assessed as part of the metering innovation agenda. Suppliers should make the prices they are offering for export more widely available in a simple and easy to understand form. Government should consider whether additional intervention is required to yield a higher value for exported electricity (or total generation) via mechanisms such as those contemplated under Option 3 (The supplier

    Melin, S.

    2006-01-01

    This presentation analyzed the current global wood pellet market and evaluated some of the forces currently driving market expansion. Global wood pellet production statistics were also presented. Large forest companies are now expanding into the energy sector and seeking to produce processing heat from biomass in addition to creating value-added products such as wood pellets, ethanol and electricity. The European biomass action plan has promised to increase production of energy from biomass from 4 per cent to 8 per cent by 2010. Various biomass boiler eco-directives have been established internationally, and some countries in Europe are now aggressively promoting the use of combined heat and power (CHP) systems. Biofuels mixing quotas have been established in various countries as well as tax relief plans for users of bio-fuels. As a result of these developments, along with various new directives, wood pellet consumption in Europe has increased from approximately 1 million tonnes in 2000 to 5 million tonnes in 2005. Consumption of wood pellets in Canada has increased only marginally in the same time period. While Canada currently exported 330,000 tonnes of wood pellets to Europe in 2006, it is expected that exports will increase to 800,000 tonnes by 2010. Other potential markets for Canadian wood pellets include South America, South Africa, Japan, and China. Production of wood pellets in China is expected to increase from current negligible production figures to approximately 50 million tonnes by 2020. Biomass research and development activities in Europe and North America are continuing to improve the calorific value of wood pellets and improve their mechanical strength. Researchers are also investigating methods of lowering wood pellet production costs. refs., tabs., figs

  13. Barriers faced by Romanian SMEs in exporting

    Directory of Open Access Journals (Sweden)

    Dana BOŞCOR

    2017-07-01

    Full Text Available This study aims to identify the most important barriers faced by Romanians SMEs in the process of exporting. The research was based on a focus group including 12 managers from different exporting companies from Brasov. The most important barriers encountered by companies were linked to currency fluctuations, methods of payment, lack of specialized staff, lack of financial resources and a low level of government support. Results from the study revealed that companies should have access at financing in order to invest in new technologies and to create higher quality products that could meet the requirements of the foreign buyers. In order to reduce the export barriers, small and medium sized exporters should create partnerships for reducing the costs of promotion in foreign markets. The government should also increase its support by offering exporters access at financing and market information at lower costs.

  14. Exporting nuclear engineering and the industry's viewpoint

    1986-01-01

    Nuclear energy offers all possibilities to reduce the energy problems in the world which arise with the world-wide increasing population and the energy demand connected with it. The Federal Republic of Germany lives on the exports of refined technical methods which also include nuclear engineering. The exports of nuclear engineering should lead to a technology transfer with guidance and training on an equal basis between the industrial and developing countries. The preconditions of exporting nuclear-technical systems are a well-functioning domestic market and a certain support by the government, especially with regard to giving guarantees for the special exports risks of these big projects. On the other hand, exports are also needed in order to be able to continue providing high-level technology for the domestic market. (UA) [de

  15. Macroeconomic Effects of Export Demand in Nigeria

    Directory of Open Access Journals (Sweden)

    Bolaji Adesola Adesoye

    2017-05-01

    Full Text Available This study examines the macroeconomic effects of aggregate export demand in Nigeria using annual time series data between 1970 and 2013. The paper made use of the ordinary least square method to analyse the long-run relationship for the period under study. The empirical results confirm that there exists a unique and significant long-run equilibrium relationship among export volume, world income, crude oil price, domestic output, exchange rate and cost of doing business. The estimated results show that domestic income has the highest elasticity, followed by world’s output and cost of doing business, which all report positive relations. Other macroeconomic factors reported negative relationship with aggregate export volume. Thus, an important policy implication of our findings is that stabilizing Nigeria’s export earnings potential by counteracting the external factors that influence adversely the Nigerian exports such as crude oil price and cost of doing business.

  16. Exports and economic growth in Nigeria

    Directory of Open Access Journals (Sweden)

    2016-09-01

    Full Text Available Nigeria is an oil dependent economy, over 90 per cent of its exports receipts in recent years flow from petroleum but this sector is currently affected by local challenges, which include insecurity, oil thefts, sabotage and an unfriendly operational environment. These challenges are generating loses for the major producers and encouraging capital flight but amidst this situation, the economy is said to be having an impressive growth. This paradox informed this research. The study was designed to see the nexus between exports and economic growth in Nigeria. Using data from the Central Bank of Nigeria spanning 1980-2011, the study with the aid of OLS regression analysis found a strong relationship between Exports and economic growth in Nigeria. Nigeria will be better served if it diversifies its export base. It must also create structures that lead to better redistribution of export incomes within the local economy.

  17. Parametric Investigation of Optimum Thermal Insulation Thickness for External Walls

    Omer Kaynakli

    2011-06-01

    Full Text Available Numerous studies have estimated the optimum thickness of thermal insulation materials used in building walls for different climate conditions. The economic parameters (inflation rate, discount rate, lifetime and energy costs, the heating/cooling loads of the building, the wall structure and the properties of the insulation material all affect the optimum insulation thickness. This study focused on the investigation of these parameters that affect the optimum thermal insulation thickness for building walls. To determine the optimum thickness and payback period, an economic model based on life-cycle cost analysis was used. As a result, the optimum thermal insulation thickness increased with increasing the heating and cooling energy requirements, the lifetime of the building, the inflation rate, energy costs and thermal conductivity of insulation. However, the thickness decreased with increasing the discount rate, the insulation material cost, the total wall resistance, the coefficient of performance (COP of the cooling system and the solar radiation incident on a wall. In addition, the effects of these parameters on the total life-cycle cost, payback periods and energy savings were also investigated.

  18. Superstar Exporters: An Empirical Investigation of Strategic Interactions in Danish Export Markets

    DEFF Research Database (Denmark)

    Ciliberto, Federico; Jäkel, Ina Charlotte

    In many countries, exports are highly concentrated among a few "superstar" firms. We estimate the export decisions of superstar firms as the result of a complete information, simultaneous, discrete choice, static entry game. We employ a dataset on the universe of Danish trade transactions by firm...... to export to a given market. Next, we run two counterfactual exercises. We show that failing to account for the strategic interaction among superstar exporters leads to: (i) overstating the probability that firms would start exporting to a market following tariff elimination by 8 percentage points; and, (ii......) overstating the probability that firms would stop exporting to a market if tariffs were imposed by 7.5 percentage points. We also show that competitive effects vary across export markets and competitors. This heterogeneity in the competitive effects implies that there exist multiple equilibria, both...

    2015-01-01

    With its decision taken on 21. October 2014 (Az.: 2 BvE 5/11) the Federal Constitutional Court (BVerfG) decided during court proceedings between administrative bodies on the scope and limits of the parliamentary right of information. Even though the proceeding did not deal with nuclear exports but arm exports, foreign trade law, however, does not only designate an export licence obligation for military weapons but also for so called dual-use goods meaning goods, which can be used both for friendly as well as for military purposes. The export of these goods requires according to the so-called Dual-Use Regulation (EG) 428/2009 a licence. Annex I category 0 of the regulation (EG) 428/2009 lists a variety of nuclear materials, plants and equipment items for which this licence applies. In the same manner as arm exports, also exports of nuclear dual-use goods are being discussed in a special cabinet committee, the Federal Security Council (BSR), which shall coordinate cross-departmentally the German security and defence policy under consideration of economic interests and which categorises its results, according to the rules of procedure, as confidential. Also legally not regulated but common ''preliminary enquiries'' at the responsible Federal Ministry or rather Federal Office of Economics and Export Control by companies which plan an export and want to affirm the general approval for their export business prior to conclusion of contract take not only place for arm exports but also for nuclear dual-use goods. The decision by the Federal Constitutional Court can be applied to consultations about the authorisation of nuclear dual-use goods.

    2010-01-01

    Full Text Available Reduction of total losses in distribution electricity supply network is considered as an important measure which serves for improvement of efficiency of electric power supply systems. This objective can be achieved by optimum distribution of reactive power sources in proper places of distribution electricity supply network. The proposed methodology is based on application of a genetic algorithm. Total expenses for installation of capacitor banks, their operation and also expenses related to electric power losses are considered as an efficiency function which is used for determination of places with optimum values of capacitor bank power. The methodology is the most efficient for selection of optimum places in the network where it is necessary to install capacitor banks with due account of their power control depending on a switched-on load value in the units.

  4. Optimum Groove Location of Hydrodynamic Journal Bearing Using Genetic Algorithm

    Full Text Available This paper presents the various arrangements of grooving location of two-groove oil journal bearing for optimum performance. An attempt has been made to find out the effect of different configurations of two groove oil journal bearing by changing groove locations. Various groove angles that have been considered are 10°, 20°, and 30°. The Reynolds equation is solved numerically in a finite difference grid satisfying the appropriate boundary conditions. Determination of optimum performance is based on maximization of nondimensional load, flow coefficient, and mass parameter and minimization of friction variable using genetic algorithm. The results using genetic algorithm are compared with sequential quadratic programming (SQP. The two grooved bearings in general have grooves placed at diametrically opposite directions. However, the optimum groove locations, arrived at in the present work, are not diametrically opposite.

    It had been studied the effect of the ionizing radiation (gamma) in mangoes for exportation, simulating the stage of preservation of the fruit during its transport, through the refrigeration in cold chamber. In a first stage they had been analyzed through loss of weight, pH, treatable acidity, soluble solid, texture and decomposition. Later, sensorial analyses had been become fulfilled (alterations of color, odor, flavor, texture). The assays had been carried through in two stadiums of maturation of the fruits, that is, 2 and 3, with the intention of studying optimum point of harvest for the best dosage of irradiation. The results disclose together that the treatment of the mangoes Tommy Atkins in the dose of 0,75 kGy was significant, with the fruit in stadium 2, for the retardation of the matureness and consequent profit of time for the exportation.

    Capital goods exports exceed $3 trillion and are volatile. This paper estimates trade elasticities for capital goods exports. For the UK and the U.S., exports depend on exchange rates. For Germany and France they do not. For Japan, exports to non-Asian countries depend on exchange rates and exports to Asian countries depend on Asia's exports to the rest of the world. For all countries, capital exports depend on GDP in the importing countries. These results imply that U.S. exports tumbled in 2...

    Full Text Available Introduction One of the main targets of planners, decision makers and governments is increasing society health with promotion and production of suitable and healthy food. One of the basic commodities that have important role in satisfaction of required human food is milk. So, some part of government and producer healthy budget allocate to milk consumption promotion by using generic advertising. If effectiveness of advertising budget on profitability is more, producer will have more willing to spend for advertising. Determination of optimal generic advertising budget is one of important problem in managerial decision making in producing firm as well as increase in consumption and profit and decrease in wasting and non-optimality of budget. Materials and Methods: In this study, optimal generic advertising budget intensity index (advertising budget share of production cost was estimated under two different scenarios by using equilibrium replacement model. In equilibrium replacement model, producer surplus are maximized in respect to generic advertising in retail level. According to market where two levels of farm and processing before retail exist and there is trade in farm and retail level, we present different models. Fixed and variable proportion hypothesis is another one. Finally, eight relations are presented for determination of milk generic advertising optimum budget. So, we use data from several resources such as previous studies, national (Iran Static center and international institute (Fao formal data and own estimation. Because there are several estimations in previous studies, we identify some scenarios (in two general scenarios for calculation of milk generic advertising optimum budget. Results and Discussion: Estimation of milk generic advertising optimum budget in scenario 1 shows that in case of one market level, fixed supplies and no trade, optimum budget is 0.4672539 percent. In case of one market level and no trade, optimum

  8. Hydrofoils: optimum lift-off speed for sailboats.

    Science.gov (United States)

    Baker, R M

    1968-12-13

    For a hydrofoil sailboat there is a unique optimum lift-off speed. Before this speed is reached, if there are no parasitic vertical hydrofoil appendages, the submerged or partially submerged hydrofoils increase drag and degrade performance. As soon as this speed is reached and the hydrofoils are fully and promptly deployed, the performance of a hydrofoil-borne craft is significantly improved. At speeds exceeding optimum lift-off speed, partially submerged hydrofoils impair performance if there is no significant effect of loading on the hydrofoil lift-to-drag ratio.

A company's strategic fit with the trading environment has to be continuously reconsidered because it is likely to erode. Managers should be well informed in order to develop their judgment and understanding of the driving forces that shape the business environment. The greatest mistakes are made by exporters who think they know a foreign market as well as they know their local one, only to find after an ill-fated export launch, that they do not.

    One approach to improving the competitiveness of photovoltaic systems is the development of designs specifically for export applications. In other words, where is it appropriate in a system design to incorporate components manufactured and/or assembled in the receiving country in order to improve the photovoltaic exports from the US? What appears to be needed is a systematic method of evaluating the potential for export from the US of PV systems for various application in different countries. Development of such a method was the goal of this project.

    This paper derives new comparative statics within a two-country version of the recent offshoring model by Antràs, Fort, and Tintelnot (2014) with nonprohibitive costs of exporting final goods. One key finding is that an asymmetric trade liberalisation might very well imply that the fractions...... of offshorers and exporters increase in one country and decrease in the other country. This model outcome occurs when competition enhances in a country experiencing a decline in its costs of international trade. The fractions of offshorers and exporters certainly increase in a small open economy experiencing...

    2018-03-01

    Full Text Available Small and Medium-sized Enterprises (SMEs are more constrained to export than their large counterparts and SMEs' limited participation in export market is more prevalent in developing than in developed countries. Extant literature suggests that SMEs encounter a set of export inhibiting factors distinct to those faced by large firms and therefore accurate identification of export barriers is crucial in fostering SMEs export. This study investigates the export barriers faced by Indonesian SMEs. The evidences were collected from 271 exporting SMEs and 226 non-exporting SMEs in seven provinces in Jawa, Madura and Bali regions. The results show that the types and severities of export barriers perceived or encountered by SMEs vary across export stages and across products/industries. Further, export barriers can be distinguished by their general or specific nature. The policy and managerial implications of the findings are discussed.

  18. Nuclear safeguards and export controls

    International Nuclear Information System (INIS)

    Mueller, H.

    1994-01-01

    Precisely from the perspective of the two most important nonnuclear weapons states, Japan and Germany, the safeguards and arms control agendas have not been finally dealt with. Because of their central position in the nonproliferation regime as nuclear suppliers and states with large nuclear energy industries, both countries are compelled to take a leading role in pursuing future reforms. In the dialogue with the nonaligned, this leadership position is helped by their nonnuclear status. In fact, Japan and Germany have some interests in common with the nonaligned states, such as the expansion of safeguards in the nuclear weapons states. To be sure, both Japan and Germany will pursue such interests with due regard to the interests of their friends and allies. For Japan, maintaining a close relationship with the United States is as important as shaping viable relations with China. Initiatives and controversies on nuclear policy must be weighed against this interest. By the same token, Germany must take into account the dense network of relations with its allies and with Russia, in addition to the German-French friendship. This will always set limits to Germany's readiness to confront the nuclear weapons states on nuclear issues. This, however, does not mean that both countries must shut up when the P 5 speak. The nuclear weapons register and the extension of the ''erga omnes'' rule in export controls, for example, should not be relegated to the dustbin of history, just because some friendly nuclear powers don't like these ideas.

  6. Optimum position for wells producing at constant wellbore pressure

    1994-12-31

    This paper deals with the determination of the optimum position of several wells, producing at constant different wellbore pressures from a two-dimensional closed-boundary reservoirs, to maximize the cumulative production or the total flow rate. To achieve this objective they authors use an improved version of the analytical solution recently proposed by Rodriguez and Cinco-Ley and an optimization algorithm based on a quasi-Newton procedure with line search. At each iteration the algorithm approximates the negative of the objective function by a cuadratic relation derived from a Taylor series. The improvement of rodriguez and Cinco`s solution is attained in four ways. First, an approximation is obtained, which works better at earlier times (before the boundary dominated period starts) than the previous solution. Second, the infinite sums that are present in the solution are expressed in a condensed form, which is relevant for reducing the computer time when the optimization algorithm is used. Third, the solution is modified to take into account the possibility of having wells starting to produce at different times. This point allows them to deal with the problem of getting the optimum position for an infill drilling program. Last, the solution is extended to include the possibility of changing the value of wellbore pressure or being able to stimulate any of the wells at any time. When the wells are producing at different wellbore pressures it is found that the optimum position is a function of time, otherwise the optimum position is fixed.

  12. Is there an optimum level for renewable energy?

    International Nuclear Information System (INIS)

    Moriarty, Patrick; Honnery, Damon

    2011-01-01

    Because continued heavy use of fossil fuel will lead to both global climate change and resource depletion of easily accessible fuels, many researchers advocate a rapid transition to renewable energy (RE) sources. In this paper we examine whether RE can provide anywhere near the levels of primary energy forecast by various official organisations in a business-as-usual world. We find that the energy costs of energy will rise in a non-linear manner as total annual primary RE output increases. In addition, increasing levels of RE will lead to increasing levels of ecosystem maintenance energy costs per unit of primary energy output. The result is that there is an optimum level of primary energy output, in the sense that the sustainable level of energy available to the economy is maximised at that level. We further argue that this optimum occurs at levels well below the energy consumption forecasts for a few decades hence. - Highlights: → We need to shift to renewable energy for climate change and fuel depletion reasons. → We examine whether renewable energy can provide the primary energy levels forecast. → The energy costs of energy rise non-linearly with renewable energy output. → There is thus an optimum level of primary energy output. → This optimum occurs at levels well below future official energy use forecasts.

    1995-01-01

    The problem of optimizing the thickness of insulation installed on large hot vessels has been solved using a semi-analytical method. Unlike the previous studies, the derived mathematical expressions for the optimum thickness and total cost of burned fuel and insulating material has been formulated in a general form which facilitates their application to any fuel and insulation characteristics and life time of the system. Moreover, the system analysis took into consideration the normally expected annual increase in fuel price. Also an expression for the net saving in fuel cost-due to the installation of insulation has been derived. The results showed that the required optimum insulation thickness increases as the lifetime of a vessel and fuel price based on the results it is recommended to: (i) Estimate the virtual lifetime of a vessel to calculate the corresponding correct optimum thickness of insulation, (ii) Install an insulation which is thicker somewhat (say 10%) than the optimum one to compensate for both the expected annual increase in fuel price and the natural deterioration in the thermal and mechanical characteristics of the insulation material. 4 figs

  3. How stem defects affect the capability of optimum bucking method?

    Abdullah Emin Akay

    2015-07-01

    Full Text Available In forest harvesting activities, computer-assisted optimum bucking method increases the economic value of harvested trees. The bucking decision highly depends on the log quality grades which mainly vary with the surface characteristics such as stem defects and form of the stems. In this study, the effects of stem defects on optimum bucking method was investigated by comparing bucking applications which were conducted during the logging operations in two different Brutian Pine (Pinus brutia Ten stands. In the applications, the first stand contained the stems with relatively more stem defects than that of the stems in the second stand. The average number of defects per log for sample trees in the first and the second stand was recorded as 3.64 and 2.70, respectively. The results indicated that optimum bucking method increased the average economic value of harvested trees by 15.45% and 8.26 % in the stands, respectively. Therefore, the computer-assisted optimum bucking method potentially provides better results than that of traditional bucking method especially for the harvested trees with more stem defects.

  8. Procedure for determining the optimum rate of increasing shaft depth

    Energy Technology Data Exchange (ETDEWEB)

    Durov, E.M.

    1983-03-01

    Presented is an economic analysis of increasing shaft depth during mine modernization. Investigations carried out by the Yuzhgiproshakht Institute are analyzed. The investigations are aimed at determining the optimum shaft sinking rate (the rate which reduces investment to the minimum). The following factors are considered: coal output of a mine (0.9, 1.2, 1.5 and 1.8 Mt/year), depth at which the new mining level is situated (600, 800, 1200, 1400 and 1600 m), four schemes of increasing depth of 2 central shafts (rock hoisting to ground surface, rock hoisting to the existing level, rock haulage to the developed level, rock haulage to the level being developed using a large diameter borehole drilled from the new level to the shaft bottom and enlarged from shaft bottom to the new level), shaft sinking rate (10, 20, 30, 40, 50 and 60 m/month), range of increasing shaft depth (the difference between depth of the shaft before and after increasing its depth by 100, 200, 300 and 400 m). Comparative evaluations show that the optimum shaft sinking rate depends on the scheme for rock hoisting (one of 4 analyzed), range of increasing shaft depth and gas content in coal seams. The optimum shaft sinking rate ranges from 20 to 40 m/month in coal mines with low methane content and from 20 to 30 m/month in gassy coal mines. The planned coal output of a mine does not influence the optimum shaft sinking rate.

  10. Optimum design for pipe-support allocation against seismic loading

    International Nuclear Information System (INIS)

    Hara, Fumio; Iwasaki, Akira

    1996-01-01

    This paper deals with the optimum design methodology of a piping system subjected to a seismic design loading to reduce its dynamic response by selecting the location of pipe supports and whereby reducing the number of pipe supports to be used. The author employs the Genetic Algorithm for obtaining a reasonably optimum solution of the pipe support location, support capacity and number of supports. The design condition specified by the support location, support capacity and the number of supports to be used is encored by an integer number string for each of the support allocation candidates and they prepare many strings for expressing various kinds of pipe-support allocation state. Corresponding to each string, the authors evaluate the seismic response of the piping system to the design seismic excitation and apply the Genetic Algorithm to select the next generation candidates of support allocation to improve the seismic design performance specified by a weighted linear combination of seismic response magnitude, support capacity and the number of supports needed. Continuing this selection process, they find a reasonably optimum solution to the seismic design problem. They examine the feasibility of this optimum design method by investigating the optimum solution for 5, 7 and 10 degree-of-freedom models of piping system, and find that this method can offer one a theoretically feasible solution to the problem. They will be, thus, liberated from the severe uncertainty of damping value when the pipe support guaranties the design capacity of damping. Finally, they discuss the usefulness of the Genetic Algorithm for the seismic design problem of piping systems and some sensitive points when it will be applied to actual design problems

  11. Global optimum path planning for a redundant space robot

    Science.gov (United States)

    Agrawal, Om P.; Xu, Yangsheng

    1991-12-01

    Robotic manipulators will play a significant role in the maintenance and repair of space stations and satellites, and other future space missions. Robot path planning and control for the above applications should be optimum, since any inefficiency in the planning may considerably risk the success of the space mission. This paper presents a global optimum path planning scheme for redundant space robotic manipulators to be used in such missions. In this formulation, a variational approach is used to minimize the objective functional. Two optimum path planning problems are considered: first, given the end-effector trajectory, find the optimum trajectories of the joints, and second, given the terminal conditions of the end-effector, find the optimum trajectories for the end-effector and the joints. It is explicitly assumed that the gravity is zero in, and the robotic manipulator is mounted on a completely free-flying base (spacecraft) and the attitude control (reaction wheels or thrust jets) is off. Linear and angular momentum conditions for this system lead to a set of mixed holonomic an nonholonomic constraints. These equations are adjoined to the objective functional using a Lagrange multiplier technique. The formulation leads to a system of Differential and Algebraic Equations (DAEs) and a set of terminal conditions. A numerical scheme is presented for forward integration of the above system of DAEs, and an iterative shooting method is used to satisfy the terminal conditions. This approach is significant since most space robots that have been developed so far are redundant. The kinematic redundancy of space robots offers efficient control and provides the necessary dexterity for extra-vehicular activity or avoidance of potential obstacles in space stations.

  14. Australian regulatory changes open crudes to export

    Energy Technology Data Exchange (ETDEWEB)

    Corbett, R.A.

    1988-01-18

    Since the price collapse of 1986, the Australian Government has been deregulating its domestic crude oils, which since the late 1960s, have been allocated solely to Australian refiners at set prices, and where no crude oil was exported. This arrangement is now being dismantled, and has allowed export since 1983, with modest free-market sales since 1985. Much of the exported crude is currently from older, established fields, but with a number of new fields that have come into production recently, some of the newer streams are beginning to find their way to many distant parts of the refining world. There are five important Australian crude oils either now being, or likely to be, exported: Barrow Island and Gippsland crudes, which are produced from fields discovered in 1960s; and Jabiru, Jackson blend, and Northwest Shelf condensate, all coming to production during the last 5 years. This article discusses each of these oils.

  17. The NPT and nuclear export controls

    International Nuclear Information System (INIS)

    Berkhout, F.

    1992-01-01

    Controls on the export of nuclear materials and technology were originally imposed in wartime and under the United States Atomic Energy Act of 1946 to restrict the supply of uranium. But there was no international agreement until the mid 1960s; before that the United States, Canada, France and the Soviet Union imposed export controls on a national basis. The Non-Proliferation Treaty, especially Articles I-IV, set out the first world wide controls on the nuclear trade. These articles are explained in the context of the relevant Committees (the Zangger Committee, the Committee on the Assurance of Supply, the National Export Committee and the Coordinating Committee for Multilateral Export Control) and Guidelines (the Nuclear Suppliers Guidelines and the International Nuclear Fuel Cycle Evaluation). Recent developments which have a bearing on nuclear trade, such as the single European market, the emergence of new supplies and the break-up of the Soviet Union, are considered. (UK)

    Coudray, M.; Perrais, J.P.

    1976-01-01

    Safety problems arising from exportation are especially handled through the French exportation of PWR stations. Regulations differ widely from one country to another. However, very large use of American regulations is made and frequently there is a tendency to harden such or such clause in the quotation. Industry must be ready to give satisfaction to such demands of customers. Sometimes also, it is a mere duplication of French stations which is above all looked for. In that case, it is the problem of using French regulations abroad which arises. Desirable changes in examination proceedings are analyzed together with a French regulation effort aiming to make easier the promotion of their use abroad. Finally, safety may be a factor of success for exportation attempts. It is shown how useless some outbiddings may be, but also how, on the contrary, speeding up of research and development effort towards specific safety problems in case of exportation, is to be promoted [fr

  10. Knowledge spillovers and new ventures’ export orientation

    OpenAIRE

    De Clercq, D.; Hessels, J.; van Stel, A.

    2008-01-01

    textabstractWe draw on the knowledge spillover literature to suggest that a country's proportion of export-oriented new ventures represents an outcome of knowledge spillovers that stem from foreign direct investment (FDI) and international trade (export spillovers) as well as a source of knowledge spillovers (entrepreneurship spillovers). To test the hypotheses, we use macrolevel data from 34 countries during the period 2002-2005. We find that the relationship between FDI and international tr...

  11. Export Control in the AREVA Group

    International Nuclear Information System (INIS)

    Zero, S.

    2013-01-01

    After the Second World War the nuclear technology was mostly considered inappropriate for the export. It remains strictly regulated today, but the development of the civil applications urged states to facilitate the peaceful uses while establishing a strict control in the domains of the internal security and the nuclear proliferation. AREVA decided to set up an Export Control program applied to all the products and in all the countries where the group operates. AREVA can export products or make transfer of technology considered as sensitive for the non-proliferation and the risks linked to the terrorism. This sensitiveness results from the nature of the products or from the country of destination and in certain cases both of them. AREVA has set up an Export Control program and an interactive e-learning training within the Group to make exports of sensitive products, raw materials and technologies more secure. The subject is rather complex, the regulations are constantly evolving, and becoming familiar with them is necessarily a gradual process, but it must be made in-depth, hence the idea of regular training sessions. The implementation of the Export Control in the AREVA Group declines in four fundamental stages: -) Policy and procedure; -) Appointment of Export Control Officers (ECO); -) Training; and -) Audit and Self Assessment. The training program is composed by the following elements: Ethics (Value Charter) of the Group, Non-proliferation, international regulations and more particularly those that are applicable in Europe (Germany and France) and in the United States. Particular attention is devoted to the Export Control practice in China, Japan and India. (A.C.)

    The EU Commission Communication of 24 April 2014 to the Council and the European Parliament ''The review of export control policy: Ensuring Security and Competitiveness in a changing world'' as well as the increasingly number of inquiries and applications to the German Federal Government (e.g. the rejection of Hermes guarantees and state funding of nuclear export and termination of bilateral cooperation in the field of nuclear technologies) once again reason to discuss the current tension between the principle of free movement of goods, competitiveness and export promotion on the one hand and the export control on the other.

  13. Renewables and exports: how Export Credit Agencies could help develop markets

    International Nuclear Information System (INIS)

    Volpi, G.; Salter, L.

    2002-01-01

    Future export markets for renewable energies have enormous potential, yet business-as-usual investment trends will not achieve that potential, write Giulio Volpi and Liam Salter. They examine the role that Export Credit Agencies - which have provided essential support for exports in the conventional energy business - could play in aiding the renewables sector, characterized as it is by small- and medium-sized enterprises. This new role will require certain reforms - but without those reforms the Export Credit Agencies will simply not be providing relevant services to new technologies and new market players. (author)

    This paper examines whether first-time exporters achieve productivity improvements through learning-by-exporting effects. The results suggest that the start of exporting to North America/Europe has a strong positive effect on sales and employment growth, R&D activity, and productivity growth. On the other hand, the start of exporting to Asia does not have any strong productivity-enhancing effects, although it does tend to boost the growth rates of sales and employment and to be associated wit...

    2016-11-01

    Full Text Available The aim of the article is to form and develop theoretical and methodological foundations for diagnostics of the enterprise export potential, which should be understood as a process of identification, analysis and assessment of the level of potential possibility and readiness of the enterprise to implement export activities taking into account the impact of interrelated internal variables (goals, technology, structure, tasks, educational and professional potential of the staff and factors of the enterprise external environment (customers, competitors, suppliers, intermediaries, contact audience, etc. in order to ensure a qualitatively new level of its development and formation of its prospects. It is determined that the key business indicators of the system for diagnostics of enterprise export potential are: the level of enterprises competitiveness in the international (global market; the level of competitiveness of enterprise products; the level of competitiveness of enterprise export products; the level of enterprise resource opportunities; the level of enterprise export performance. Prospects for further research in this direction are to develop a classification (specifically detailed list of objectives of the enterprise diagnostics by the level of detail (element, partial, complex, taking into account diagnostics of export potential of the enterprise as part of diagnostic objective.

  16. Export of carbon from chloroplasts at night

    Schleucher, J.; Vanderveer, P.J.; Sharkey, T.D. [Univ. of Wisconsin, Madison, WI (United States)

    1998-12-01

    Hexose export from chloroplasts at night has been inferred in previous studies of mutant and transgenic plants. The authors have tested whether hexose export is the normal route of carbon export from chloroplasts at night. The authors used nuclear magnetic resonance to distinguish glucose (Glc) made from hexose export and Glc made from triose export. Glc synthesized in vitro from fructose-6-phosphate in the presence of deuterium-labeled water had deuterium incorporated at C-2, whereas synthesis from triose phosphates caused C-2 through C-5 to become deuterated. In both tomato (Lycopersicon esculentum L.) and bean (phaseolus vulgaris L.), Glc from sucrose made at night in the presence of deuterium-enriched water was deuterated only in the C-2 position, indicating that >75% of carbon is exported as hexoses at night. In darkness the phosphate in the cytosol was 28 mM, whereas that in the chloroplasts was 5 mW, but hexose phosphates were 10-fold higher in the cytosol than in the chloroplasts. Therefore, hexose phosphates would not move out of chloroplasts without the input of energy. The authors conclude that most carbon leaves chloroplasts at night as Glc, maltose, or higher maltodextrins under normal conditions.

  17. Nuclear export controls and nuclear safeguards

    International Nuclear Information System (INIS)

    Sevini, F.

    2013-01-01

    The export control of dual use goods has developed since the early seventies to counter nuclear proliferation. The paper provides an overview of dual-use export control issues also in relation with the Additional Protocol to the Comprehensive Safeguards Agreement, which requires States to provide declarations of the export of the controlled items listed in its Annex II, derived from the Nuclear Suppliers Group Trigger list. Recommendations for improvement are proposed. On the EU level, the paper summarises the framework set by the European Council Regulation 428/2009, requiring Member States to impose control on exports, brokering and transit of dual use goods. The Regulation includes the so-called 'EU dual-use control list' integrating the lists of dual-use items defined by the international regimes and requires also the control on intangible technology transfers as foreseen by U.N. Security Council Resolution 1540. ESARDA has recently launched a new sub-Working Group on export control, which raised large interest and may evolve to a full-fledged working group. Export control may provide an opportunity of technical collaboration between ESARDA and INMM. The paper is followed by the slides of the presentation. (author)

  18. Export-led Growth Hypothesis: Turkey Application

    Directory of Open Access Journals (Sweden)

    İsmail KÜÇÜKAKSOY

    2015-12-01

    Full Text Available This paper aims to investigate validity of “Export-led Growth Hypothesis” for Turkey using quarterly data in period from 2003:Q1 to 2015:Q1. Hypothesis argues that there is causality relationship from real export to real Gross Domestic Product (GDP. Johansen cointegration test, Gregory-Hansen cointegration test, Toda-Yamamoto causality test, Fully Modified Ordinary Least Squares (FMOLS, Canonical cointegrating regression (CCR and Dynamic ordinary least squares (DOLS methods were used in this study. Findings can be summarized as follows: a According to Johansen cointegration test there is no relationship among variables in the long-run whereas Gregory-Hansen cointegration test has determined relationship in the long-run; b According to Toda-Yamamoto causality test there is bidirectional causality between real export and real GDP. This finding proves the validity of “Export-led Growth Hypothesis” for Turkey; c According to FMOLS, CCR, DOLS methods a 1% increase in the real export increases the real GDP by 1.5195%, 1.5552%, 1.3171% respectively in the long-run. These methods prove the validity of “Export-led Growth Hypothesis” for Turkey.

  1. The optimal currency-peg for an oil exporting country: The case of Saudi Arabia

    International Nuclear Information System (INIS)

    Almasbahi, M.S.

    1990-01-01

    In a world of generalized floating exchange rates, it is not enough to solve the problem of exchange rate policy by determining whether to peg or float the currency under consideration. It is also necessary to choose to what major currency to peg. The main purpose of this study is to investigate and determine empirically the optimum currency peg for the Saudi riyal. To accomplish this goal, a simple conventional trade model, that includes variables found in many other studies of import and export demand, was used. In addition, an exchange rate term was added as a separate independent variable in the import and export demand equations in order to assess the effect of exchange rate on the trade flows. The criteria for the optimal currency peg in this study were based on two factors. First, the error statistics for projected imports and exports using alternative exchange rate regimes. Second, variances of projected imports, exports and trade balance using alternative exchange rate regimes. The exchange rate has a significant impact on the Saudia Arabian trade flows which implies that changes in the riyals value affect the Saudi trade deficit. Moreover, the exchange rate has a more powerful effect on its aggregate imports than on the world demand for its exports. There is also a strong support for the hypothesis that the exchange rate affects the value of the Saudi bilateral trade with its five major trade partners. On the aggregate level, the SDR peg seems to be the best currency peg for the Saudi riyal since it provides the best prediction errors and the lowest variance for the trade balance. Finally, on the disaggregate level, the US dollar provides the best performance and yields the best results among all the six currency pegs considered in this study

  6. RECENT APPROACHES IN THE OPTIMUM CURRENCY AREAS THEORY

    Directory of Open Access Journals (Sweden)

    AURA SOCOL

    2011-04-01

    Full Text Available This study is dealing with the endogenous characteristic of the OCA criteria, starting from the idea that a higherconformity of the business cycles will result in a better timing of the economic cycles and, thus, in getting closerto the quality of an optimum currency area. Thus, if the classical theory is focused on a static approach of theproblem, the new theories assert that these conditions are dynamic, and they cannot be positively affected evenby the establishment of the Economic and Monetary Union. The consequences are overwhelming, as theendogenous approach shows that a monetary union can be achieved even if all the conditions mentioned inMundell’s optimum currency areas theory are not met, showing that some of them may also be met subsequentto the unification. Thus, a country joining a monetary union, althogh it does not meet the criteria for an optimumcurrency area, will ex post lead to the increase of the integration and business cycle correlation degree.

  7. Determining optimum aging time using novel core flooding equipment

    DEFF Research Database (Denmark)

    Ahkami, Mehrdad; Chakravarty, Krishna Hara; Xiarchos, Ioannis

    2016-01-01

    New methods for enhanced oil recovery are typically developed using core flooding techniques. Establishing reservoir conditions is essential before the experimental campaign commences. The realistic oil-rock wettability can be obtained through optimum aging of the core. Aging time is affected...... by temperature, crude oil, formation brine, and coreplug lithology. Minimum time can significantly reduce the experimental cost while insufficient aging time can result in false conclusions. Real-time online resistivity measurements of coreplugs are presented and a novel method is introduced for determining...... the optimum aging time regardless of variations in crude oil, rock, and brine properties. State of the art core flooding equipment has been developed that can be used for consistently determining the resistivity of the coreplug during aging and waterflooding using advanced data acquisition software...

  8. Optimum design of B-series marine propellers

    Directory of Open Access Journals (Sweden)

    M.M. Gaafary

    2011-03-01

    Full Text Available The choice of an optimum marine propeller is one of the most important problems in naval architecture. This problem can be handled using the propeller series diagrams or regression polynomials. This paper introduces a procedure to find out the optimum characteristics of B-series marine propellers. The propeller design process is performed as a single objective function subjected to constraints imposed by cavitation, material strength and required propeller thrust. Although optimization software of commercial type can be adopted to solve the problem, the computer program that has been specially developed for this task may be more useful for its flexibility and possibility to be incorporated, as a subroutine, with the complex ship design process.

    Song, Dong Soo; Lee, Chang Sup; Lee Jae Yong; Kim, Yo Han; Lee, Dong Hyuk [Korea Electric Power Research Institute, Taejon (Korea, Republic of)

    1997-12-31

    To determine the optimum pressurizer water level during normal operation for Kori unit 1, performance and safety analysis are performed. The methodology is developed by evaluating {sup d}ecrease in secondary heat removal{sup e}vents such as Loss of Normal Feedwater accident. To demonstrate optimum pressurizer level setpoint, RETRAN-03 code is used for performance analysis. Analysis results of RETRAN following reactor trip are compared with the actual plant data to justify RETRAN code modelling. The results of performance and safety analyses show that the newly established level setpoints not only improve the performance of pressurizer during transient including reactor trip but also meet the design bases of the pressurizer volume and pressure. 6 refs., 5 figs.

  10. Parallel operation of NH3 screw compressors - the optimum way

    Science.gov (United States)

    Pijnenburg, B.; Ritmann, J.

    2015-08-01

    The use of more smaller industrial NH3 screw compressors operating in parallel seems to offer the optimum way when it comes to fulfilling maximum part load efficiency, increased redundancy and other highly requested features in the industrial refrigeration industry today. Parallel operation in an optimum way can be selected to secure continuous operation and can in most applications be configured to ensure lower overall operating economy. New compressors are developed to meet requirements for flexibility in operation and are controlled in an intelligent way. The intelligent control system keeps focus on all external demands, but yet striving to offer always the lowest possible absorbed power, including in future scenarios with connection to smart grid.

    1996-01-01

    We present a new methodology for obtaining optimum values of the integrated cost of utility investment with customer interruption in distribution planning for electric power systems by determining the reliability cost and worth of the distribution system. Reliability cost refers to investment cost of the utility in achieving a defined level of reliability. Reliability worth is the benefit gained by the utility customer from an increase of reliability. A computer program has been developed to determine comparative reliability indices for a typical distribution network. With the average interruption cost, outage duration, average disconnected load, cost data for distribution equipment, etc. being known, the relation between reliability cost, reliability worth and reliability at the specified load point are obtained. The optimum reliability of the distribution system is then determined from the minimum cost to the utility with customer interruption. The applicability of this approach is demonstrated by several practical networks. (Author)

    Full Text Available Nineteen strains of microorganisms were screened for uricase production. Gliomastix gueg was recognized to produce high levels of the enzyme. The optimum fermentation conditions for uricase production by Gliomastix gueg were examined. Results showed that uric acid medium was the most favorable one, the optimum temperature was at 30ºC, and incubation period required for maximum production was 8 days with aeration level at 150 rpm and at pH 8.0. Sucrose proved to be the best carbon source, uric acid was found to be the best nitrogen source. Both, dipotassium hydrogen phosphate and ferrous chloride as well as some vitamins gave the highest amount of uricase by Gliomastix gueg.

    This work can be separated into two main parts. First, the behavior of the solution of an elliptic variational equation is analyzed when the domain is submitted to a small perturbation. The case of inequations is also considered. Secondly the previous results are used for deriving an optimum design algorithm. This algorithm was suggested by the center-method proposed by Huard. Numerical results show the superiority of the method on other different optimization techniques [fr

    Full Text Available http://dx.doi.org/10.5902/1980509812353This study analyzed the degree of concentration in worldwide exports of forest products in the period rangingfrom 1961 to 2008. The data used are available at the United Nations Food and Agriculture Organization(FAO. The concentration was determined by the concentration ratio [HR (k], the Herfindahl-HirschmanIndex (HHI, Theil Entropy Index (E and the Gini index (G. The main conclusions were: The aggregateBrazilian share in the world exports of forest products is increasing over time; the most important sectors inthe aggregate world exports of forest products, in decreasing order, were pulp, lumber, paper and cardboard,wooden panels, saw and fire wood. According to Bain, the concentration ratio of the four and eight largestexporters of forest products is moderately low; the HHI and Theil Entropy (E show a reduction in theconcentration of world exports of forest products and greater competition among the countries that sell suchproducts; the Gini index indicates that despite the increase in export of forest products over the period ofanalysis, a smaller number of competitors concentrate increasingly larger shares of international exports of these products; summary indices (HHI, E and G indicated that increased competition has not led to a moreequitable distribution of forest products so as to bring down inequalities and concentration of profits in thesector; despite the downward trend in CR (4 and CR (8, there is an increase in G, probably because theeconomies of scale in the international trade have been held by few competitors; caution is recommendedin the analysis of summary indices (HHI, E and G which had better be checked jointly with the partialindices [CR (k] in order to avoid wrong conclusions; countries with a significant share in total exports, suchas Brazil, should seek business strategies to retain competitive advantages, especially those arising fromeconomies of scale.

  19. WHAT IS THE OPTIMUM SIZE OF GOVERNMENT: A SUGGESTION

    Full Text Available What is the optimum size of government? When the rule of law and the establishment of private property rights are taken into consideration, it is clear that the answer will not be at some 0%. On the other hand, when the experience of the old Soviet Union, East Germany and North Korea is considered, the answer will not be at some 100% either. Therefore, extreme points should not be the right answer. This study offers using normal distribution to answer this question. The study has revealed the following findings: (i The total amount of public expenditures as % of GDP, a is at minimum level at 4.55% rate, b is at optimum level at 13.4% rate, c is at maximum level at 31.7%. (ii Thus, as a fiscal rule, countries should: a choose the total amount of public expenditures as % of GDP ≤ 31.7% b target 13.4%. (iii Tree dimensional (3D normal distribution demonstrates that a healthy market system could be built upon a healthy government system (iv This approach rejects Wagner’s law. In a healthy growing economy, optimum government size could be kept at 13.4%. (v The UK, the USA and the European countries have been in the Keynesian-Marxist area, which reduces their average growth.

    This work aims to obtain an optimum analysis sequence for environmental gamma-ray spectroscopy by means of Genie 2000 (Canberra). Twenty different analysis sequences were customized using different peak area percentages and different algorithms for: 1) peak finding, and 2) peak area determination, and with or without the use of a library -based on evaluated nuclear data- of common gamma-ray emitters in environmental samples. The use of an optimum analysis sequence with certified nuclear information avoids the problems originated by the significant variations in out-of-date nuclear parameters of commercial software libraries. Interference-free gamma ray energies with absolute emission probabilities greater than 3.75% were included in the customized library. The gamma-ray spectroscopy system (based on a Ge Re-3522 Canberra detector) was calibrated both in energy and shape by means of the IAEA-2002 reference spectra for software intercomparison. To test the performance of the analysis sequences, the IAEA-2002 reference spectrum was used. The z-score and the reduced χ 2 criteria were used to determine the optimum analysis sequence. The results show an appreciable variation in the peak area determinations and their corresponding uncertainties. Particularly, the combination of second derivative peak locate with simple peak area integration algorithms provides the greater accuracy. Lower accuracy comes from the combination of library directed peak locate algorithm and Genie's Gamma-M peak area determination. (Author)

  3. Optimum Waveforms for Differential Ion Mobility Spectrometry (FAIMS)

    Science.gov (United States)

    Shvartsburg, Alexandre A.; Smith, Richard D.

    2009-01-01

    Differential mobility spectrometry or field asymmetric waveform ion mobility spectrometry (FAIMS) is a new tool for separation and identification of gas-phase ions, particularly in conjunction with mass-spectrometry. In FAIMS, ions are filtered by the difference between mobilities in gases (K) at high and low electric field intensity (E) using asymmetric waveforms. An infinite number of possible waveform profiles make maximizing the performance within engineering constraints a major issue for FAIMS technology refinement. Earlier optimizations assumed the non-constant component of mobility to scale as E2, producing the same result for all ions. Here we show that the optimum profiles are defined by the full series expansion of K(E) that includes terms beyond the 1st that is proportional to E2. For many ion/gas pairs, the first two terms have different signs, and the optimum profiles at sufficiently high E in FAIMS may differ substantially from those previously reported, improving the resolving power by up to 2.2 times. This situation arises for some ions in all FAIMS systems, but becomes more common in recent miniaturized devices that employ higher E. With realistic K(E) dependences, the maximum waveform amplitude is not necessarily optimum and reducing it by up to ∼20 – 30% is beneficial in some cases. The present findings are particularly relevant to targeted analyses where separation depends on the difference between K(E) functions for specific ions. PMID:18585054

    The authors have reviewed U.S. Export-Import Bank (Eximbank) transactions involving chemicals exported to Iraq from January 1987 to August 1990. Specifically, the authors examined (1) whether there was any evidence that the Eximbank financed the export of dual-use chemicals to Iraq and (2) what the Eximbank`s role was in monitoring and controlling chemical exports. Results are based primarily on a review of documents provided to them by the Eximbank. They did not verify the Eximbank data or corroborate it with the records of the banks or exporters involved in the transactions. There was no evidence in the documents they reviewed to suggest that the Eximbank financed the export of dual-use chemicals (chemicals with both commercial and military applications that could be used for chemical weapons) -- as defined by the Department of Commerce -- to Iraq between January 1987 and August 1990. There were approximately 190 transactions between Iraq and the Eximbank during this period. They focused their review on the eight transactions involving pesticides and related products. The Eximbank has no responsibility or authority for monitoring or controlling the export of chemicals or any other commodities: the Departments of Commerce and State and the US Customs Service share those responsibilities. Nevertheless, the Eximbank has recently developed specific procedures to review applications for financing chemical exports. However, such procedures were not in place when the Eximbank approved the applications for seven of eight pesticide transactions that occurred between January 1987 and August 1990.

    Full Text Available Soybean, sesame seed, and rice bran meal proteins were hydrolyzed with two enzymes, namely, papain and bromelain. Experiments were carried out to elucidate the optimum condition for each enzyme when acting on each substrate seperately. Results revealed that the highest relative activities for papain were achieved with E/S 0.06 , 0.29, 0.19 and pH 7.2, 7.0, 7.0 for soybean, sesame,and rice bran meal proteins, respectively. Optimum temperature for papain while hydrolysing the three substrates was 50 ºC. When using bromelain optimum E/S resulting in highest relative activities were 0.067, 0.058 and 0.21 for soybean, sesame,and rice bran meal protein, respectively. Optimum pH was 6.0 and optimum temperature was 45 ºC for bromelain when hydrolysing the protein of the three substrates. A numerical correlation of enzymatic behaviour for the different substrates was calculated.Proteínas de haba de soja, semilla de sésamo y harina de germen de arroz se hidrolizaron con dos enzimas, denominadas, papaina y bromelaina. Se han llevado a cabo experimentos para determinar las condiciones óptimas de cada enzima cuando actúan separadamente sobre cada sustrato. Los resultados mostraron que las mayores actividades relativas para la papaina se consiguieron con una E/S 0,06, 0,29, 0,19 y un pH 7.2, 7.0, 7.0 para las proteínas de haba de soja, sésamo y harina de germen de arroz, respectivamente. La temperatura óptima para la papaina durante la hidrólisis de los tres sustratos fue de 50 ºC. Cuando se usa bromelaina las relaciones E/S óptimas que proporcionaron mayor actividad relativa fueron 0.067, 0.058 y 0.21 para las proteínas de habas de soja, sésamo y harina de germen de arroz respectivamente. El pH óptimo fue 6.0 y la temperatura óptima 45 ºC para la bromelaina cuando se hidroliza la proteína de los tres sustratos.

    In order to ensure that the policy to avoid the proliferation of nuclear weapons is complied with, the French Administration applies stricter controls over the export of certain sensitive products, materials and equipment. To this effect, lists of such products, materials and equipment are published in the form of Notices to exporters and periodically revised. This Notice repeals and replaces the previous Notice published in the Official Gazette of 21 January 1986. Annex I contains the list of materials whose export is subject to nuclear non-proliferation controls. Annex II lists the equipment whose export is subject to the same controls. Annex III includes the list of large nuclear units for which an application for prior approval of export must be submitted to the Administrations concerned. (NEA) [fr

    1993-06-01

    Electricity exports from Hydro-Quebec to utilities in the USA significantly affects the economy and environment of Quebec. These exports may be arranged under interconnection agreements to sell excess capacity and production during off-peak periods or under firm sales contracts. Hydro-Quebec exports could also replace power plants that would otherwise be needed in the USA. The economic environment for Hydro-Quebec exports to the USA is reviewed along with the regulatory environment applicable to international trade (General Agreement on Tariffs and Trade, Canada-USA Free Trade Agreement, North American Free Trade Agreement), Quebec (Canadian federal and provincial law), and the USA (federal and state law). A jurisdictional analysis of power export contracts is then presented, citing examples of contracts already signed by Hydro-Quebec with utilities in New York and New England. Contract law and contract provisions are discussed, including common clauses and particular clauses. Suggestions are made for new clauses that would improve the electricity trade. 215 refs., 13 figs., 3 tabs

    2015-01-01

    While exporting firms and non-exporters have been compared across several dimensions, empirical comparisons on the basis of environmental performance are relatively few. Moreover, analyzing the environmental implications of firm-level exports is not trivial due to non-random selection into exporting. In this light, we examine the impact of exporting on firms' energy efficiency by resorting to an instrumental variables strategy based on a differencing approach (Pitt and Rosenzweig, 1990). Utilizing data from Indonesia, we find (i) exporting to reduce the use of fuels (relative to electricity) and (ii) concerns over endogeneity of exporting status to be relevant. - Highlights: • We examine the impact of exporting on firms' energy efficiency. • We employ cost share equations, firm-level data from Indonesia, and an instrumental variables strategy. • Exporting is found to reduce the use of fuels (relative to electricity).

    Shapar, M.

    1976-01-01

    Since the division of the former US Atomic Energy Commission's tasks, the regulation and control of import and export of nuclear materials and equipment has become the responsability of the Nuclear Regulatory Commission (NRC). The import and export of nuclear fuels, equipment and reactors are therefore subject to prior licensing by the Commission. This requirement aims to guarantee that such activities will not create serious hazards for defense and national safety, and that the exported products will not be diverted from their peaceful uses. The relevant applicable legal provisions are based on the Atomic Energy Act of 1954 and on the detailed regulations issued by the Commission. Under the pressure of public opinion, there is a current tendency to restrict these activities because of the hazards they present, in particular during transport, until the Commission has completed all the necessary studies.

  17. Export Products and Services Quality Management

    2011-05-01

    Full Text Available Quality became the management imperative in the last time and will continue to be the key to success in the future. We often see the words “quality first”, and demands for quality invade every sphere of activity, from the motor vehicles we drive, to the domestic appliances we use, the food we eat and, of course, the products and services we import and export. Quality represents the goal of every business and it is focused on the customer. Satisfying the requirements of the customer is a dynamic activity: both customers and their needs are changing continuous and the suppliers have to recognize this. When it comes to international trade, no exporting country can afford to compromise on quality. The current global economic climate calls for export marketing and promotion efforts with assurances of superior and consistent quality in products and services, rather associated with lower prices.

    Delaleau, Mildred; Borden, Katherine L. B.

    2015-01-01

    Nuclear mRNA export plays an important role in gene expression. We describe the mechanisms of mRNA export including the importance of mRNP assembly, docking with the nuclear basket of the nuclear pore complex (NPC), transit through the central channel of the NPC and cytoplasmic release. We describe multiple mechanisms of mRNA export including NXF1 and CRM1 mediated pathways. Selective groups of mRNAs can be preferentially transported in order to respond to cellular stimuli. RNAs can be selected based on the presence of specific cis-acting RNA elements and binding of specific adaptor proteins. The role that dysregulation of this process plays in human disease is also discussed. PMID:26343730

    This paper examines Pakistan's competitiveness in export of selected horticulture commodities by employing set of revealed comparative advantage (RCA) and revealed competitive advantage indices with respect to global trade. Results demonstrate that Pakistan has comparative and competitive advantage over the period under analysis and indicates a transition from comparative and competitive disadvantage to comparative and competitive advantage during the period under analysis. Tangerines, mandarins, clem have maintained relatively higher revealed comparative advantage as compared to other categories for the whole period under analysis. Onion export has revealed comparative advantage with some fluctuations over time. The research indicates that Pakistan's comparative and competitive advantages have been increasing in all the selected commodities during period under analysis which indicates the potential of horticulture exports for foreign exchange earnings. There is need to strengthen comparative and competitive advantage in horticulture sector by policy support and facilitating role by all stakeholders. (author)

  2. Clean energy exports and the Kyoto Protocol

    Bramley, M.

    2002-01-01

    This paper discussed Canada's attempt in international negotiations to gain credits for energy exports that may result in greenhouse gas emission reductions in the United States. It examined how well founded this position is from an environmental perspective and in terms of international equity and political reality. The author emphasized that the clean energy export issue does not provide a legitimate reason to delay Canada's ratification of the Kyoto Protocol, and cautioned that further renegotiation of Kyoto targets for the first commitment period would not be practical and would jeopardize Canada's international standing. The author did note, however, that for the second commitment period, this issue could be reintroduced. Although the problem can potentially be resolved by granting credits to producers and exempting emissions, it was suggested that the most effective approach would be for countries to factor energy export considerations into their negotiating positions

    Migrants may become entrepreneurs in their host countries.

    The PLOT3D export tool for Tecplot solves the problem of modified data being impossible to output for use by another computational science solver. The PLOT3D Exporter add-on enables the use of the most commonly available visualization tools to engineers for output of a standard format. The exportation of PLOT3D data from Tecplot has far reaching effects because it allows for grid and solution manipulation within a graphical user interface (GUI) that is easily customized with macro language-based and user-developed GUIs. The add-on also enables the use of Tecplot as an interpolation tool for solution conversion between different grids of different types. This one add-on enhances the functionality of Tecplot so significantly, it offers the ability to incorporate Tecplot into a general suite of tools for computational science applications as a 3D graphics engine for visualization of all data. Within the PLOT3D Export Add-on are several functions that enhance the operations and effectiveness of the add-on. Unlike Tecplot output functions, the PLOT3D Export Add-on enables the use of the zone selection dialog in Tecplot to choose which zones are to be written by offering three distinct options - output of active, inactive, or all zones (grid blocks). As the user modifies the zones to output with the zone selection dialog, the zones to be written are similarly updated. This enables the use of Tecplot to create multiple configurations of a geometry being analyzed. For example, if an aircraft is loaded with multiple deflections of flaps, by activating and deactivating different zones for a specific flap setting, new specific configurations of that aircraft can be easily generated by only writing out specific zones. Thus, if ten flap settings are loaded into Tecplot, the PLOT3D Export software can output ten different configurations, one for each flap setting.

    Developing countries with a nuclear programme are about a dozen according to information obtained by IAEA. They are a group hostile to any restriction imposed on nuclear technology export and consider that such restriction is contrary to the global concept of North/South co-operation which provides for transfer of advanced technology. In particular, they object to the fact that nuclear weapon states make use of Article 4 of the NPT. Industrialised countries are required to keep a balance between a regular and stable supply system and the assurance that exported nuclear installations and materials are placed under international control according to the IAEA Safeguards.

    2016-02-01

    Full Text Available A statistical model combined with CFD (computational fluid dynamic method was used to explain the detailed phenomena of the process parameters, and a series of experiments were carried out for propylene polymerisation by varying the feed gas composition, reaction initiation temperature, and system pressure, in a fluidised bed catalytic reactor. The propylene polymerisation rate per pass was considered the response to the analysis. Response surface methodology (RSM, with a full factorial central composite experimental design, was applied to develop the model. In this study, analysis of variance (ANOVA indicated an acceptable value for the coefficient of determination and a suitable estimation of a second-order regression model. For better justification, results were also described through a three-dimensional (3D response surface and a related two-dimensional (2D contour plot. These 3D and 2D response analyses provided significant and easy to understand findings on the effect of all the considered process variables on expected findings. To diagnose the model adequacy, the mathematical relationship between the process variables and the extent of polymer conversion was established through the combination of CFD with statistical tools. All the tests showed that the model is an excellent fit with the experimental validation. The maximum extent of polymer conversion per pass was 5.98% at the set time period and with consistent catalyst and co-catalyst feed rates. The optimum conditions for maximum polymerisation was found at reaction temperature (RT 75 °C, system pressure (SP 25 bar, and 75% monomer concentration (MC. The hydrogen percentage was kept fixed at all times. The coefficient of correlation for reaction temperature, system pressure, and monomer concentration ratio, was found to be 0.932. Thus, the experimental results and model predicted values were a reliable fit at optimum process conditions. Detailed and adaptable CFD results were capable

    A spark counter of the type developed by Pestov has been tested with the aim of searching for an optimum time response function, changing voltage, content of noble and quencher gases, pressure and energy-loss. Replacing the usual argon by neon has brought an improvement of the resolution and a significant reduction of tails in the time response function. It has been proven that a counter as long as 90 cm can deliver, using neon gas mixture, a time resolution σ<60 ps with about 1% absolute tail and an efficiency of about 90%

    An optimum filter-based method for discrimination of neutrons and gamma-rays in a mixed radiation field is presented. The existing filter-based implementations of discriminators require sample pulse responses in advance of the experiment run to build the filter coefficients, which makes them less practical. Our novel technique creates the coefficients during the experiment and improves their quality gradually. Applied to several sets of mixed neutron and photon signals obtained through different digitizers using stilbene scintillator, this approach is analyzed and its discrimination quality is measured.

    This study considers periodic preventive maintenance policies, which maximizes the availability of a repairable system with major repair at failure. Three types of preventive maintenance are performed, namely: imperfect preventive maintenance (IPM), perfect preventive maintenance (PPM) and failed preventive maintenance (FPM). The probability that preventive maintenance is perfect depends on the number of imperfect maintenances conducted since the previous renewal cycle, and the probability that preventive maintenance remains imperfect is not increasing. The optimum preventive maintenance time that maximizes availability is derived. Various special cases are considered. A numerical example is given

    2000-10-01

    Designing optimal frac jobs is a complex and time-consuming process. It usually involves the use of a two- or three-dimensional computer model. For the computer models to perform as intended, a wealth of input data is required. The input data includes wellbore configuration and reservoir characteristics such as porosity, permeability, stress and thickness profiles of the pay layers as well as the overburden layers. Among other essential information required for the design process is fracturing fluid type and volume, proppant type and volume, injection rate, proppant concentration and frac job schedule. Some of the parameters such as fluid and proppant types have discrete possible choices. Other parameters such as fluid and proppant volume, on the other hand, assume values from within a range of minimum and maximum values. A potential frac design for a particular pay zone is a combination of all of these parameters. Finding the optimum combination is not a trivial process. It usually requires an experienced engineer and a considerable amount of time to tune the parameters in order to achieve desirable outcome. This paper introduces a new methodology that integrates two virtual intelligence techniques, namely, artificial neural networks and genetic algorithms to automate and simplify the optimum frac job design process. This methodology requires little input from the engineer beyond the reservoir characterizations and wellbore configuration. The software tool that has been developed based on this methodology uses the reservoir characteristics and an optimization criteria indicated by the engineer, for example a certain propped frac length, and provides the detail of the optimum frac design that will result in the specified criteria. An ensemble of neural networks is trained to mimic the two- or three-dimensional frac simulator. Once successfully trained, these networks are capable of providing instantaneous results in response to any set of input parameters. These

    A modified method has been evolved to form the loss coefficients of an electrical power system network by decoupling load and generation and thereby creating additional fictitious load buses. The system losses are then calculated and co-ordinated to arrive at an optimum scheduling of generation using the standard co-ordination equation. The method presented is superior to the ones currently available, in that it is applicable to a multimachine system with random variation of load and it accounts for limits in plant generations and line losses. The precise nature of results and the economy in the cost of energy production obtained by this method is quantified and presented. (author).

    Fourier optical pattern recognition has wonderful properties (high speed, space-invariant operation, low power consumption, target location) and one terrible property (It can work perfectly only for the rare, uninteresting case of two linearly separable categories). More powerful discrimination methods lack the other wonderful properties. I show here how to have it both ways at once. By using roughly the Vapnik- Chervonenkis (VC) dimension number of properly trained Fourier filters in parallel and performing pixel-by-pixel thresholding on the output planes, we can assemble a net output plane which achieves provably optimum, predictable discrimination on any sets.

    Full Text Available his article is about investigation of export-led growth and growth-led export hypotheses in case of Pakistan exports to top three exports partners namely: USA, UAE and UK. Time series data over the period of 1975 to 2012 has been used. Augmented dickey- fuller test has been used to check unit root within data. Co-integration among the variables has been explored by employing the Johansen's co integration technique. Granger causality test has been used to investigate nature causality among variables under investigation. Johansen's co-integration test revealed the presence of co-integration among variables. As major portion of Pakistani exports approximately 30 percent is towards the top three exports partners, so the investigation of export-led growth and growth-led export hypotheses in case of Pakistan's exports to USA, UAE and UK can helpful for policy makers to adopt a suitable policy prescriptions which finally could lead to enhancement and improvement of exports relations with USA, UAE, and UK. This research can lead towards understanding about the dependency of exports and economic growth on each other.

    The aims of the present study are to determine the optimum compression rate in terms of file size reduction and diagnostic quality of the images after compression and evaluate the transmission speed of original or each compressed images. The material consisted of 24 extracted human premolars and molars. The occlusal surfaces and proximal surfaces of the teeth had a clinical disease spectrum that ranged from sound to varying degrees of fissure discoloration and cavitation. The images from Digora system were exported in TIFF and the images from conventional intraoral film were scanned and digitalized in TIFF by Nikon SF-200 scanner(Nikon, Japan). And six compression factors were chosen and applied on the basis of the results from a pilot study. The total number of images to be assessed were 336. Three radiologists assessed the occlusal and proximal surfaces of the teeth with 5-rank scale. Finally diagnosed as either sound or carious lesion by one expert oral pathologist. And sensitivity and specificity and kappa value for diagnostic agreement was calculated. Also the area (Az) values under the ROC curve were calculated and paired t-test and oneway ANOVA test was performed. Thereafter, transmission time of the image files of the each compression level were compared with that of the original image files. No significant difference was found between original and the corresponding images up to 7% (1:14) compression ratio for both the occlusal and proximal caries (p<0.05). JPEG3 (1:14) image files are transmitted fast more than 10 times, maintained diagnostic information in image, compared with original image files. 1:14 compressed image file may be used instead of the original image and reduce storage needs and transmission time.

    Highlights: ► A new optimal distributed generation placement algorithm is proposed. ► Optimal number, sizes and locations of the DGs are determined. ► Technical factors like loss, voltage sag problem are minimized. ► The percentage savings are optimized. - Abstract: The present paper proposes a new formulation for the optimum distributed generator (DG) placement problem which considers a hybrid combination of technical factors, like minimization of the line loss, reduction in the voltage sag problem, etc., and economical factors, like installation and maintenance cost of the DGs. The new formulation proposed is inspired by the idea that the optimum placement of the DGs can help in reducing and mitigating voltage dips in low voltage distribution networks. The problem is configured as a multi-objective, constrained optimization problem, where the optimal number of DGs, along with their sizes and bus locations, are simultaneously obtained. This problem has been solved using genetic algorithm, a traditionally popular stochastic optimization algorithm. A few benchmark systems radial and networked (like 34-bus radial distribution system, 30 bus loop distribution system and IEEE 14 bus system) are considered as the case study where the effectiveness of the proposed algorithm is aptly demonstrated.

    Building Codes are increasingly required to be responsive to social and economic policy concerns. In 1990 the State of Connecticut passes An Act Concerning Global Warming, Public Act 90-219, which mandates the revision of the state building code to require that buildings and building elements be designed to provide optimum cost-effective energy efficiency over the useful life of the building. Further, such revision must meet the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) Standard 90.1 - 1989. As the largest electric energy supplier in Connecticut, Northeast Utilities (NU) sponsored a pilot study of the cost effectiveness of alternative building code standards for commercial construction. This paper reports on this study which analyzed design and construction means, building elements, incremental construction costs, and energy savings to determine the optimum cost-effective building code standard. Findings are that ASHRAE 90.1 results in 21% energy savings and alternative standards above it result in significant additional savings. Benefit/cost analysis showed that both are cost effective

    Müllerian mimicry between chemically defended preys is a textbook example of natural selection favouring phenotypic convergence onto a shared warning signal. Studies of mimicry have concentrated on deciphering the ecological and genetic underpinnings of dramatic switches in mimicry association, producing a well-known mosaic distribution of mimicry patterns across geography. However, little is known about the accuracy of resemblance between natural comimics when the local phenotypic optimum varies. In this study, using analyses of wing shape, pattern and hue, we quantify multimodal phenotypic similarity between butterfly comimics sharing the so-called postman pattern in different localities with varying species composition. We show that subtle but consistent variation between populations of the localized species, Heliconius timareta thelxinoe, enhance resemblance to the abundant comimics which drive the mimicry in each locality. Those results suggest that rarer comimics track the changes in the phenotypic optimum caused by gradual changes in the composition of the mimicry community, providing insights into the process by which intraspecific diversity of mimetic pattern may arise. Furthermore, our results suggest a multimodal evolution of similarity, with coordinated convergence in different features of the phenotype such as wing outline, pattern and hue. Finally, multilocus genotyping allows estimating local hybridization rates between H. timareta and comimic H. melpomene in different populations, raising the hypothesis that mimicry refinement between closely related comimics may be enhanced by adaptive introgression at loci modifying the accuracy of resemblance. © 2016 The Authors.

    ABSTRACT We investigated various essential factors for optimum infrared thermography for cattle clinics. The effect of various factors on the detection of surface temperature was investigated in an experimental room with a fixed ambient temperature using a square positioned on a wall. Various factors of animal objects were examined using cattle to determine the relationships among presence of hair, body surface temperature, surface temperature of the eyeball, the highest temperature of the eye circle, rectum temperature and ambient temperature. Also, the surface temperature of the flank at different time points after eating was examined. The best conditions of thermography for cattle clinics were determined and were as follows: (1) The distance between a thermal camera and an object should be fixed, and the camera should be set within a 45-degree angle with respect to the objects using the optimum focal length. (2) Factors that affect the camera temperature, such as extreme cold or heat, direct sunshine, high humidity and wind, should be avoided. (3) For the comparison of thermographs, imaging should be performed under identical conditions. If this is not achievable, hairless parts should be used. PMID:23759714

    Communications systems builders continue to search for signal formats and receiver architectures that can provide the most efficient utilization of their subsystems, which include power amplifiers as well as transmit and receive apertures. Receivers requiring very small amounts of received power are of particular interest in communications links where transmission distances are very long and losses are large, such as from Deep Space. Helstrom and others ([1],[2],[3]) initiated the study of optimum signal reception using quantum mechanical signal models. They derived the mathematical description and predicted performance of receivers that optimize certain criteria, such as Minimum Probability of Error (MPE). Unfortunately, practical implementation of their proposed receivers has still not been achieved. In parallel, technology has advanced to where noiseless photon counters can be used to achieve quite good performance ([4]). We show here that, when an end-to-end error correction code is added, in fact such a system can out-perform the "optimum" MPE system at low signal powers. In this report, we derive the formulation of a quantum receiver that is shown to be uniformly better than either the MPE or photon-counting receiver.

    2018-01-01

    Full Text Available Affected by regular tides, bidirectional water flows play a crucial role in surface river systems. Using optimization theory to design a water quality monitoring network can reduce the redundant monitoring nodes as well as save the costs for building and running a monitoring network. A novel algorithm is proposed to design an optimum water quality monitoring network for tidal rivers with bidirectional water flows. Two optimization objectives of minimum pollution detection time and maximum pollution detection probability are used in our optimization algorithm. We modify the Multi-Objective Particle Swarm Optimization (MOPSO algorithm and develop new fitness functions to calculate pollution detection time and pollution detection probability in a discrete manner. In addition, the Storm Water Management Model (SWMM is used to simulate hydraulic characteristics and pollution events based on a hypothetical river system studied in the literature. Experimental results show that our algorithm can obtain a better Pareto frontier. The influence of bidirectional water flows to the network design is also identified, which has not been studied in the literature. Besides that, we also find that the probability of bidirectional water flows has no effect on the optimum monitoring network design but slightly changes the mean pollution detection time.

    Discarded scrap tyres have become one of the major environmental problems nowadays. Several studies have been carried out to reuse waste tires as an additive or sand replacement in concrete with appropriate percentages of tire rubber, called as rubberized concrete to solve this problem. The main objectives of this study are to investigate the flexural strength performance of concrete when adding the rubber ash and also to analyse the optimum content of rubber ash in concrete prisms. The performance total of 30 number of concrete prisms in size of 100mm x 100mm x 500 mm were investigated, by partially replacement of rubber ash with percentage of 0%, 3%, 5%, 7% and 9% from the volume of the sand. The flexural strength is increased when percentage of rubber ash is added 3% from control concrete prism, RA 0 for both concrete prism age, 7 days and 28 days with value 1.21% and 0.976% respectively. However, for RA 5, RA 7 and RA 9, the flexural strength was decreased compared to the control for both age, 7 days and 28 days. In conclusion, 3% is the optimum content of rubber ash in concrete prism for both concrete age

    Full Text Available Bioedegradable nanoparticles are intensively investigated for their potential applications in drug delivery systems. Being a biocompatible and biodegradable polymer, chitosan holds great promise for use in this area. This investigation was concerned with determination and optimization of the effective parameters involved in the production of chitosan nanoparticles using ionic gelation method. Studied variables were concentration and pH of the chitosan solution, the ratio of chitosan to sodium tripolyphosphate therein and the molecular weight of chitosan. For this purpose, Taguchistatistical method was used for design of experiments in three levels. The size of chitosan nanoparticle was determined using laser light scattering. The experimental results showed that concentration of chitosan solution was the most important parameter and chitosan molecular weight the least effective parameter. The optimum conditions for preparation of nanoparticles were found to be 1 mg/mL chitosan solution with pH=5, chitosan to sodium tripolyphosphate ratio of 3 and chitosan molecular weight of 200,000 daltons. The average nanoparticle size at optimum conditions was found to be about 150 nm.

    2014-08-01

    Full Text Available To optimize tower crane selection and supporting design, lifting requirements (as well as stability should be examined, followed by a review of economic feasibility. However, construction engineers establish plans based on data provided by equipment suppliers since there are no tools with which to thoroughly examine a support design's suitability for various crane types, and such plans lack the necessary supporting data. In such cases it is impossible to optimize a tower crane selection to satisfy lifting requirements in terms of cost, and to perform lateral support and foundation design. Thus, this study is intended to develop an optimum tower crane selection and supporting design management method based on stability. All cases that are capable of generating an optimization of approximately 3,000 ˜ 15,000 times are calculated to identify the candidate cranes with minimized cost, which are examined. The optimization method developed in the study is expected to support engineers in determining the optimum lifting equipment management.

    Due to their large biomass forests assume an important role in the global carbon cycle by moderating the greenhouse effect of atmospheric pollution. The Kyoto Protocol recognises this contribution by allocating carbon credits to countries which are able to create new forest areas. Sequestrated carbon provides an environmental benefit thus must be taken into account in cost–benefit analysis of afforestation projects. Furthermore, like timber output carbon credits are now tradable assets in the carbon exchange. By using British data, this paper looks at the issue of identifying optimum felling age by considering carbon sequestration benefits simultaneously with timber yields. The results of this analysis show that the inclusion of carbon benefits prolongs the optimum cutting age by requiring trees to stand longer in order to soak up more CO 2 . Consequently this finding must be considered in any carbon accounting calculations. - Highlights: ► Carbon sequestration in forestry is an environmental benefit. ► It moderates the problem of global warming. ► It prolongs the gestation period in harvesting. ► This paper uses British data in less favoured districts for growing Sitka spruce species.

    Full Text Available This article describes the concept and development of a knowledge-based advisory system for the optimum utilisation of South African wool for the benefit of present and potential investors and other interested parties. Wool is a natural animal fibre produced in varying quantities around the world. The wool fibre is far from homogenous; its type and quality, such as fineness and length, depending on the breed of sheep and the environmental conditions prevailing during its growth. Wool is used in a variety of end uses, ranging from fi ne worsted suiting, to hand knitting yarn, carpets, blankets and aircraft upholstery, its use depending largely on its fibre fineness and length. The wool industry is one of the oldest agricultural industries in South Africa, playing an important economic role as an earner of foreign exchange, and providing a living to many people. Wool is produced in many parts of South Africa under extensive, semi-extensive or intensive conditions, and is largely an export commodity. It is produced and traded in a sophisticated free market business environment into the international market place, where supply and demand forces determine price levels. More than 90% of locally produced wool is exported in an unprocessed or semi-processed form which detrimentally affects employment, foreign exchange and income-generating opportunities associated with value-addition prior to export. To reduce the amount of wool exported in unprocessed or semi-processed form, wool-processing enterprises need to be established to produce internationally marketable end products. Therefore, South Africa needs to attract investors into the wool sector, who will set up manufacturing mills in an economically sustainable manner. Potential and present investors in the South African (S.A. wool industry need easily accessible and up-to-date information on the production statistics, processing properties and end-use pplications of the wool they need for the

Wool is used in a variety of end uses, ranging from fi ne worsted suiting, to hand knitting yarn, carpets, blankets and aircraft upholstery, its use depending largely on its fibre fineness and length. The wool industry is one of the oldest agricultural industries in South Africa, playing an important economic role as an earner of foreign exchange, and providing a living to many people. Wool is produced in many parts of South Africa under extensive, semi-extensive or intensive conditions, and is largely an export commodity. It is produced and traded in a sophisticated free market business environment into the international market place, where supply and demand forces determine price levels. More than 90% of locally produced wool is exported in an unprocessed or semi-processed form which detrimentally affects employment, foreign exchange and income-generating opportunities associated with value-addition prior to export. To reduce the amount of wool exported in unprocessed or semi-processed form, wool-processing enterprises need to be established to produce internationally marketable end products. Therefore, South Africa needs to attract investors into the wool sector, who will set up manufacturing mills in an economically sustainable manner. Potential and present investors in the South African (S.A. wool industry need easily accessible and up-to-date information on the production statistics, processing properties and end-use pplications of the wool they need for the

  5. South Korea's export strategy

    2016-01-01

    The main assets of KEPCO is its capacity to build nuclear power plants on-time and its important feedback experience in reactor exploitation. KEPCO manages thermal plants and all the nuclear plants operating in South Korea. In 2009 a contract was signed for the construction of 4 reactors in United Arab Emirates by KEPCO but since then no other major contract has been signed. The Korean export offer includes the APR1400 reactor that is a third generation reactor with a power output of 1400 MWe, 4 APR1400 (Advanced Power Reactor) are being built in Korea. The offer includes also a second generation reactor: the OPR1000 (Optimised Power Reactor) with a power output of 1000 MWe. The OPR1000 has its origin in a technology transfer from Westinghouse. Only 12 OPR1000 are operating in the world and all are situated in Korea. KEPCO is developing a third generation of the OPR1000 reactor named the APR1000 intended for export. The Korean export strategy aims at emergent first-time buyer countries and asian countries. The Korean offer does not neglect niche markets like small reactors and research reactors. The SMART project is a reactor with an output of 300 MWth that will be able to produce electricity and desalinate water. The Korean export strategy relies on a strong cohesiveness and involvement between public and private actors in the nuclear sector. (A.C.)

  20. Challenges to nuclear export controls today

    International Nuclear Information System (INIS)

    Chatelus, R.; Sevini, F.; Janssens, W.; Michel, Q.

    2014-01-01

    Nuclear energy and nuclear proliferation programs are potentially inter-twinned, which is a point to be taken into account when analysing the development of civil nuclear energy, both domestically and as foreign investment. International agreements ensure that the adhering countries fulfil their obligations and do not abuse civil nuclear programs for the production of nuclear weapons. Uranium enrichment is the process currently most focused on in this respect by recent news and recent technological and commercial developments. But also the so-called reactor-based pathway, with extraction of plutonium from spent nuclear fuel by reprocessing remains in the spotlight of inspectors. Two of the main and complementary pillars on which the prevention of such diversion relies, are Strategic Export Control and International Safeguards. Strategic export control is a key barrier against nuclear proliferation. In many countries including the EU, it is set by a legal framework, envisaging implementation, enforcement and prosecution. The goods that can exported only with authorisations are those identified by the international export control regimes; primarily the Nuclear Suppliers Group in the case of nuclear items. It is complemented by nuclear safeguards measures, and especially in the past few years, by the IAEA State Level concept, which looks at the overall country's potential, including its industrial structure to derive conclusions on the absence of undeclared activities. However, the strict control of goods and knowledge is a moving target, since technological developments, globalisation and the intensifying exchange of information via the worldwide web offer increasing opportunities to proliferators to acquire sensitive items and competencies, and create bigger challenges to enforcement, calling for new responses. Research and development programmes must be directed towards supporting the adaptation of current proliferation containment systems to these new
