301 | 17,205 | Projections onto the range of the exponential Radon transform and reconstruction algorithms | Inverse Problems | In recent articles Metz and Pan have introduced a large class of methods for inverting the exponential Radon transform that are parametrized by a function ω of two variables. We show that when ω satisfies a certain constraint, the corresponding inversion method uses projection to the range of the transform. The addition of another constraint on ω makes this projection orthogonal with respect to a weighted inner product. Their quasi-optimal algorithm uses the projection that is orthogonal with respect to the ordinary inner product. | ["Clarkson E."] | ["7005797126"] | 1,999 | 9 | [] | 10.1088/0266-5611/15/2/014 | Article | English | [{"id": "60010065", "name": "Optical Sciences Center, University of Arizona, Tucson, AZ 85721, United States", "fullName": "Optical Sciences Center, University of Arizona", "reference": "a", "fullAddress": "Tucson, AZ 85721, United States", "departmentId": "103550683"}] |
302 | 17,251 | Quantum stochastic calculus and quantum nonlinear filtering | Journal of Multivariate Analysis | A *-algebraic indefinite structure of quantum stochastic (QS) calculus is introduced and a continuity property of generalized nonadapted QS integrals is proved under the natural integrability conditions in an infinitely dimensional nuclear space. The class of nondemolition output QS processes in quantum open systems is characterized in terms of the QS calculus, and the problem of QS nonlinear filtering with respect to nondemolition, continuous measurements is investigated. The stochastic calculus of a posteriori conditional expectations in quantum observed systems is developed and a general quantum filtering stochastic equation for 2 QS process is derived. An application to the description of the spontaneous collapse of the quantum spin under continuous observation is given. © 1992. | ["Belavkin V.P."] | ["7004580130"] | 1,992 | 225 | ["conditional expectation", "output process", "quantum filtering", "quantum system", "stochastic calculus"] | 10.1016/0047-259X(92)90042-E | Article | English | [{"id": "60027509", "name": "Università di Roma II, Rome, Italy", "fullName": "Università di Roma II", "reference": "a", "fullAddress": "Rome, Italy", "departmentId": null}] |

304 | 17,298 | Learning and Incentive-Compatible Mechanisms for Public Goods Provision: An Experimental Study | Journal of Political Economy | This is the first systematic experimental study of the comparative performance of two incentive-compatible mechanisms for public goods provision: the basic quadratic mechanism by Groves and Ledyard and the paired-difference mechanism by Walker. Our experiments demonstrate that the performance of the basic quadratic mechanism under a high punishment parameter is far better than that of the same mechanism under a low punishment parameter, which, in turn, is better than that of the paired-difference mechanism. We estimate three individual behavioral models: an exponentialized relative payoff sum model outperforms the generalized fictitious play model. We also provide a sufficient condition for convergence under the basic quadratic mechanism. | ["Chen Y.", "Tang F.-F."] | ["8889740400", "7201979717"] | 1,998 | 53 | [] | 10.1086/250024 | Article | English | [{"id": "60025778", "name": "University of Michigan, United States", "fullName": "University of Michigan", "reference": "a", "fullAddress": "United States", "departmentId": null}, {"id": "60017161", "name": "University of Bonn, National University of Singapore, Singapore", "fullName": "University of Bonn, National University of Singapore", "reference": "b", "fullAddress": "Singapore", "departmentId": null}] |
305 | 17,341 | An algorithm for solving linearly constrained optimization problems | Mathematical Programming | An algorithm for minimization of functions of many variables, subject possibly to linear constraints on the variables, is described. In it a subproblem is solved in which a quadratic approximation is made to the object function and minimized over a region in which the approximation is valid. A strategy for deciding when this region should be expanded or contracted is given. The quadratic approximation involves estimating the hessian of the object function by a matrix which is updated at each iteration by a formula recently reported by Powell [6]. This formula enables convergence of the algorithm from any feasible point to be proved. Use of such an approximation, as against using exact second derivatives, also enables a reduction of about 60% to be made in the number of operations to solve the subproblem. Numerical evidence is reported showing that the algorithm is efficient in the number of function evaluations required to solve well known test problems. © 1972 North-Holland Publishing Company. | ["Fletcher R."] | ["7201875201"] | 1,972 | 35 | [] | 10.1007/BF01584540 | Article | English | [{"id": "60004643", "name": "A.E.R.E., Harwell, Didcot, Berks, United Kingdom", "fullName": "A.E.R.E.", "reference": "a", "fullAddress": "Harwell, Didcot, Berks, United Kingdom", "departmentId": "106817171"}] |
306 | 17,482 | A magnetomechanical model of the magnetic brush | Journal of Applied Physics | A mathematical model based on first principles has been formulated to predict the behavior of the magnetic brush in the development zone of an electrophotographic process. As a first approximation, the brush is modeled as a collection of straight chains whose length distribution is derived from a magnetic energy minimization principle. Results with the model are compared with experimental measurements of the tangential and normal forces exerted by the brush on the photoreceptor.

307 | 17,526 | Institutional linkages and policy networks in the federal system of West Germany | Publius | West German federalism can be understood as a system of interlocking, but distinct and autonomous, "policy networks." Sectoral policy networks are integrated into overarching networks. The traditional pluri-centrism of state and societal institutions is contrasted with an integrated (but not centralized) economic policy network oriented toward national homogeneity. With the decline of Keynesian macroeconomic policy, however, regional policy networks are being upgraded. At the same time, the political party system and the politicization of administrative agencies have led to the development of an overarching network in which bargaining and accommodation have precedence over hierarchical centralization.

309 | 17,646 | Explanation-Based Learning: An Alternative View | Machine Learning | In the last issue of this journal Mitchell, Keller, and Kedar-Cabelli presented a unifying framework for the explanation-based approach to machine learning. While it works well for a number of systems, the framework does not adequately capture certain aspects of the systems under development by the explanation-based learning group at Illinois. The primary inadequacies arise in the treatment of concept operationality, organization of knowledge into schemata, and learning from observation. This paper outlines six specific problems with the previously proposed framework and presents an alternative generalization method to perform explanation-based learning of new concepts. © 1986, Kluwer Academic Publishers.

311 | 17,758 | Smooth interpolation in triangles | Journal of Approximation Theory | The purpose of this paper is to describe new schemes of interpolation to the boundary values of a function defined on a triangle. These schemes are affine-invariant and combine several Hermite interpolants. They are not, however, finite dimensional schemes. The simplest scheme is exact for quadratic functions, uses rational linear weighting ("blending") functions analogous to the methods of Mangeron and Coons for rectangles, and satisfies a maximum principle. For any positive integer p, there is an analogous scheme which interpolates on the boundary to the function and all its partial derivatives of order p - 1.

314 | 17,843 | A modified chebyshev pseudospectral method with an O(n<sup>−1</sup>) time step restriction | Journal of Computational Physics | The extreme eigenvalues of the Chebyshev pseudospectral differentiation operator are O(N<sup>2</sup>), where N is the number of grid points. As a result of this, the allowable time step in an explicit time marching algorithm is O(N<sup>−2</sup>) which, in many cases, is much below the time step dictated by the physics of the PDE. In this paper we introduce a new differentiation operator whose eigenvalues are O (N) and the allowable time step is O (N<sup>−1</sup>). The new algorithm is based on interpolating at the zeroes of a parameter dependent, nonperiodic trigonometric function. The properties of the new algorithm are similar to those of the Fourier method but in addition it provides highly accurate solution for nonperiodic boundary value problems. © 1993 by Academic Press, Inc. | ["Kosloff D.", "Tal-Ezer H."] | ["7003414015", "6506582879"] | 1,993 | 202 | [] | 10.1006/jcph.1993.1044 | Article | English | [{"id": "60005681", "name": "Department of Geophysical and Planetary Sciences, Raymond and Beverly Sackler Faculty of Exact Sciences, Tel-Aviv University, Tel-Aviv 69 978, Israel", "fullName": "Department of Geophysical and Planetary Sciences, Raymond and Beverly Sackler Faculty of Exact Sciences, Tel-Aviv University", "reference": "a", "fullAddress": "Tel-Aviv 69 978, Israel", "departmentId": "103328576"}, {"id": "60005681", "name": "Institute for Computer Applications in Science and Engineering, School of Mathematical Sciences, Raymond and Beverly Sackler Faculty of Exact Sciences, Tel-Aviv University, Tel-Aviv 69 978, Israel", "fullName": "Institute for Computer Applications in Science and Engineering, School of Mathematical Sciences, Raymond and Beverly Sackler Faculty of Exact Sciences, Tel-Aviv University", "reference": "b", "fullAddress": "Tel-Aviv 69 978, Israel", "departmentId": "106053000"}] |

The NPARC (National PARC) code is employed as an example for analyzing the flow through a supersonic inlet. The flowfield is divided into subregions called blocks. The parallel computation of the problem normally requires commanication between each block after each time step of an explicit Runge-Kutta integration scheme. In the developed procedure, the boundary conditions are frozen for k = 10-29 time steps, and blocks are integrated in time without communication with each other during this period. When the boundary conditions are updated, an oscillatory error rs introduced into the solution with a fundamental period of 4k time steps, which is then filteted in time. As a result, the communication cost of parallel computing is significantly reduced.

318 | 18,147 | Exact decomposition of the algebraic Riccati equation of deterministic multimodeling optimal control problems | IEEE Transactions on Automatic Control | In this paper we show how to exactly decompose the algebraic Riccati equations of deterministic multimodeling in terms of one pure-slow and two pure-fast algebraic Riccati equations. The algebraic Riccati equations obtained are of reduced-order and nonsymmetric. However, their O(∈) perturbations(where ∈ = ∥<sub>∈2</sub><sup>∈⊥</sup>∥ and ∈<sub>⊥</sub>, ∈<sub>2</sub> are small positive singular perturbation parameters) are symmetric. The Newton method is perfectly suited for solving the nonsymmetric reduced-order pure-slow and pure-fast algebraic Riccati equations since excellent initial guesses are available from their O(∈) perturbed reduced-order symmetric algebraic Riccati equations that can be solved rather easily. The proposed decomposition scheme might facilitates new approaches to mutimodeling control problems that are conceptually simpler and numerically more efficient than the ones previously used. © 2000 IEEE. | ["Coumarbatch C.", "Gajic Z."] | ["6507147214", "55307612500"] | 2,000 | 17 | ["Algebraic riccati equation", "Linear systems", "Multimodeling", "Optimal control", "Singular perturbations"] | 10.1109/9.847124 | Article | English | [{"id": "60119141", "name": "Department of Mathematics, Rutgers University, New Brunswick, NJ 08903, United States", "fullName": "Department of Mathematics, Rutgers University", "reference": "a", "fullAddress": "New Brunswick, NJ 08903, United States", "departmentId": "123158424"}, {"id": "60119141", "name": "Department of Electrical and Computer Engineering, Rutgers University, Piscataway, NJ 08854-8058, United States", "fullName": "Department of Electrical and Computer Engineering, Rutgers University", "reference": "b", "fullAddress": "Piscataway, NJ 08854-8058, United States", "departmentId": "123139397"}] |

Our key idea is that many programming bugs can be explained by novices inappropriately using their knowledge of step-by-step procedural specifications in natural language. We view programming bugs as patches generated in response to an impasse reached by the novice while developing a program. We call such patching strategies bug generators. Several of our bug generators describe how natural language preprogramming knowledge is used by novices to create patches. Other kinds of bug generators are also discussed. We describe a representation both for novice natural language preprogramming knowledge and novice fragmentary programming knowledge. Using these representations and the bug generators, we evaluate the model by analyzing four interviews with novice programmers. © 1985 Lawrence Erlbaum Associates, Inc.

The extent to which monetary control under the new regime has been limited by an exchange rate objective is examined. Through estimation of an explicit Bank of Japan (BoJ) reaction function, we find evidence that the BoJ operating instrument has been systematically manipulated with a view to maintain short-term money control but that this objective has often been dominated by an attempt to moderate yen- dollar exchange rate fluctuations. © 1988. | ["Hutchison M.M."] | ["7006152180"] | 1,988 | 14 | [] | 10.1016/0261-5606(88)90030-7 | Article | English | [{"id": "60024941", "name": "University of California at Santa Cruz, Santa Cruz, CA 95064, United States", "fullName": "University of California at Santa Cruz", "reference": "a", "fullAddress": "Santa Cruz, CA 95064, United States", "departmentId": null}, {"id": "60031864", "name": "Federal Reserve Bank of San Francisco, San Francisco, CA 94105, United States", "fullName": "Federal Reserve Bank of San Francisco", "reference": "b", "fullAddress": "San Francisco, CA 94105, United States", "departmentId": null}] |

However, this methodology cannot be applied in the nonlinear regression framework. In this paper we develop consistent estimators for nonlinear regression specifications when errors in variables are present. We apply our methodology to estimation of Engel curves on household data. First, we find that the 'Lesser-Working' specification of budget shares regressed on the log of income or expenditure should be generalized to higher-order terms in log income. Also, we find that errors in variables in either reported income or expenditure should be accounted for. Lastly and perhaps most interesting, we find rather strong support for the Gorman rank restriction on the matrix of coefficients for the polynomial terms in income. © 1995. | ["Hausman J.A.", "Newey W.K.", "Powell J.L."] | ["7006286384", "6603072064", "7403542084"] | 1,995 | 108 | ["Engel curves", "Errors in variables"] | 10.1016/0304-4076(94)01602-V | Article | English | [{"id": "60022195", "name": "Department of Economics, MIT, Cambridge, MA 02139, United States", "fullName": "Department of Economics, MIT", "reference": "a", "fullAddress": "Cambridge, MA 02139, United States", "departmentId": "105332148"}, {"id": "60003269", "name": "Princeton University, Princeton, NJ 08544, United States", "fullName": "Princeton University", "reference": "b", "fullAddress": "Princeton, NJ 08544, United States", "departmentId": null}] |

We say that a planar part is polygonal if its convex hull is a polygon. We consider the following problem: given a list of n vertices describing a polygonal part whose initial orientation is unknown, find the shortest sequence of mechanical gripper actions that is guaranteed to orient the part up to symmetry in its convex hull. We show that such a sequence exists for any polygonal part by giving an O[n<sup> 2</sup> log n) algorithm for finding the sequence. Since the gripper actions do not require feedback, this result implies that any polygonal part can be oriented without sensors. © 1993 Springer-Verlag New York Inc. | ["Goldberg K.Y."] | ["35453491100"] | 1,993 | 292 | ["Compliance", "Compliant motion planning", "Grasping", "Motion planning with uncertainty", "Parts feeding", "Planning", "Robotics"] | 10.1007/BF01891840 | Article | English | [{"id": "60029311", "name": "Institute for Robotics and Intelligent Systems, Computer Science Department, University of Southern California, Los Angeles, 90089-0273, CA, United States", "fullName": "Institute for Robotics and Intelligent Systems, Computer Science Department, University of Southern California", "reference": "a", "fullAddress": "Los Angeles, 90089-0273, CA, United States", "departmentId": "100243703"}] |

335 | 19,414 | The M/G/1 queue with processor sharing and its relation to a feedback queue | Queueing Systems | The central model of this paper is an M/M/1 queue with a general probabilistic feedback mechanism. When a customer completes his ith service, he departs from the system with probability 1-p(i) and he cycles back with probability p(i). The mean service time of each customer is the same for each cycle. We determine the joint distribution of the successive sojourn times of a tagged customer at his loops through the system. Subsequently we let the mean service time at each loop shrink to zero and the feedback probabilities approach one in such a way that the mean total required service time remains constant. The behaviour of the feedback queue then approaches that of an M/G/1 processor sharing queue, different choices of the feedback probabilities leading to different service time distributions in the processor sharing model. This is exploited to analyse the sojourn time distribution in the M/G/1 queue with processor sharing. Some variants are also considered, viz., an M/M/1 feedback queue with additional customers who are always present, and an M/G/1 processor sharing queue with feedback. © 1991 J.C. Baltzer A.G.

339 | 19,618 | Vehicle routing with stochastic demands and restricted failures | ZOR Zeitschrift für Operations Research Methods and Models of Operations Research | This paper considers a class of stochastic vehicle routing problems (SVRPs) with random demands, in which the number of potential failures per route is restricted either by the data or the problem constraints. These are realistic cases as it makes little sense to plan vehicle routes that systematically fail a large number of times. First, a chance constrained version of the problem is considered which can be solved to optimality by algorithms similar to those developed for the deterministic vehicle routing problem (VRP). Three classes of SVRP with recourse are then analyzed. In all cases, route failures can only occur at one of the last k customers of the planned route. Since in general, SVRPs are considerably more intractable than the deterministic VRPs, it is interesting to note that these realistic stochastic problems can be solved as a sequence of deterministic traveling salesman problems (TSPs). In particular, when k=1 the SVRP with recourse reduces to a single TSP. © 1993 Physica-Verlag. | ["Dror M.", "Laporte G.", "Louveaux F.V."] | ["7005100478", "7101734278", "6603153633"] | 1,993 | 38 | [] | 10.1007/BF01415995 | Article | English | [{"id": "60010065", "name": "Decision Sciences, College of Business and Public Adminstration, The University of Arizona, Tucson, 85721, Arizona, United States", "fullName": "Decision Sciences, College of Business and Public Adminstration, The University of Arizona", "reference": "a", "fullAddress": "Tucson, 85721, Arizona, United States", "departmentId": "103550726"}, {"id": "60009507", "name": "Centre de recherche sur les trasports, Université de Montréal, H3C 3J7, succursale A.

341 | 19,756 | GT cell formation for minimizing the intercell parts flow | International Journal of Production Research | A methodology is proposed to design a GT cell by considering the intercell parts flow in GT cellular manufacturing systems. The problem of GT cell formation is described in a graph using the quantities to be produced in the specified time period and the process routes for producing the products. The objective of this paper is to minimize the total number of parts produced in more than one cell. The problem, formulated as a quadratic assignment problem (QAP), is solved using both Lagrangean relaxation technique and the optimality conditions of quadratic program. Furthermore, in order to obtain the giobal optimal solution rather than the local optimal solution, a branch-and-bound algorithm is employed. Finally, numerical examples are used to show the effectiveness of the solution techniques and GT cell formation procedure. Moreover, a computer simulation is presented, showing the effectiveness of cellular manufacturing systems. © 1992 Taylor & Francis Group, LLC. | ["Song S.", "Hitomi K.", "Hitomi K.", "Hitomi K."] | ["7403350157", "56938147700", "57029992600", "57029974400"] | 1,992 | 42 | [] | 10.1080/00207549208948188 | Article | English | [{"id": "60019716", "name": "Department of Industrial Engineering, Hiroshima Institute of Technology, Saeki-ku, Hiroshima, 731-51, 2-1-1, Miyake, Japan", "fullName": "Department of Industrial Engineering, Hiroshima Institute of Technology", "reference": "a", "fullAddress": "Saeki-ku, Hiroshima, 731-51, 2-1-1, Miyake, Japan", "departmentId": "104005240"}, {"id": "60011001", "name": "Department of Precision Engineering, Kyoto University, Japan", "fullName": "Department of Precision Engineering, Kyoto University", "reference": "b", "fullAddress": "Japan", "departmentId": "103592634"}, {"id": "60016835", "name": "Beijing Institute of Technology, Southwestern Jiaotong University, China", "fullName": "Beijing Institute of Technology, Southwestern Jiaotong University", "reference": "c", "fullAddress": "China", "departmentId": null}, {"id": "60033100", "name": "Nanjing University, China", "fullName": "Nanjing University", "reference": "d", "fullAddress": "China", "departmentId": null}, {"id": "60011132", "name": "Ohio University, OH, United States", "fullName": "Ohio University", "reference": "e", "fullAddress": "OH, United States", "departmentId": null}] |
342 | 19,758 | New Connectivity and MSF Algorithms for Shuffle-Exchange Network and Pram | IEEE Transactions on Computers | Parallel algorithms for finding the connected components (CC) and a minimum spanning FOREST (MSF) of an undirected graph are presented. The primary model of computation considered is that called “shuffle-exchange network” in which each processor has its own local memory, no memory is shared, and communication among processors is done via a fixed degree network. This model is very convenient for actual realization. Both algorithms have depth of 0(log2 n) while using n2 processors. Here n is the number of vertices in the graph. The algorithms are first presented for the PRAM (parallel RAM) model, which is not realizable, but much more convenient for the design and presentation of algorithms. The CC and MSF algorithms are no exceptions. The CC PRAM algorithm is a simplification of the one appearing in [17]. A modification of this algorithm yields a simple and efficient MSF algorithm. Both have depth of O(log m) and they use m processors, where m is the number of edges in the graph.

The method involves 'sharpening' the data by making them slightly more clustered than before, and then computing the estimator in the usual way, but from the sharpened data rather than the original data. The transformation depends in a simple, explicit way on the smoothing parameter employed for the density estimator, which may be based on classical kernel methods, orthogonal series, histosplines, singular integrals or other linear or approximately-linear methods. Bias is reduced by an order of magnitude, at the expense of a constant-factor increase in variance. © 1999 Biometrika Trust. | ["Choi E.", "Hall P."] | ["7402121838", "57203346769"] | 1,999 | 56 | ["Bandwidth", "Bias reduction", "Kernel density estimation", "Nadaraya-watson estimator", "Nonparametric density estimation", "Orthogonal series", "Ridge estimation"] | 10.1093/biomet/86.4.941 | Article | English | [{"id": "60008950", "name": "Centre for Mathematics and Its Applications, Australian National University, Canberra, ACT 0200, Australia", "fullName": "Centre for Mathematics and Its Applications, Australian National University", "reference": "a", "fullAddress": "Canberra, ACT 0200, Australia", "departmentId": "103494083"}] |

In this paper, a nonlinear model-based backstepping control strategy will be proposed for simultaneous air-to-fuel ratio control and speed tracking in passenger/light-duty automobile engines. For comparison purposes, a multi-surface sliding mode controller and an integrated speed-density air-to-fuel controller with attached engine speed regulation will be implemented.

357 | 20,809 | Correlation dimension and systematic geometric effects | Physical Review A | Correlation-dimension calculations have been widely undertaken in attempts to understand various physical and other natural phenomena. Some of these studies have perhaps been incautious in their claims. On the other hand, some authors have been sharply critical of such work. These criticisms hinge on doubts about data-set size. In particular, Smith [Phys. Lett. A 133, 283 (1988)] has suggested that 42D points are a minimum number of data points, where D is the embedding dimension. He has suggested that, as a result, correlation-dimension calculations are limited to dimensions less than 5 or 6 even on supercomputers. By implication, many published results are placed into doubt, discouraging people from undertaking such calculations. We review the concept of critical embedding dimension and undertake a detailed analysis of data-size requirements, which culminates in tight error estimates for determination of correlation dimension. We conclude that, while data requirements are still substantial, they are not nearly so extreme as has been suggested, making the determination of correlation dimension from data sets feasible. Previously reported doubtful calculations of correlation dimension can be reviewed in the light of explicit error estimates. © 1990 The American Physical Society. | ["Nerenberg M.A.H.", "Essex C."] | ["7003854126", "7005347167"] | 1,990 | 153 | [] | 10.1103/PhysRevA.42.7065 | Article | English | [{"id": "60010884", "name": "Department of Applied Mathematics, University of Western Ontario, London, Ont.

In the specific example chosen we are trying to locate part of the brainstem, and associated structures of the upper spinal cord and mesencephalon. and determine its size, shape and orientation. The approach is in two parts: firstly, to use a controlled, deformable model, based on superquadric geometric primitives as an initial estimate and apply genetic algorithms as the technique for solving the complex optimization problem of defining an approximate encompassing envelope within which the object will be found.

The “entropy parameter” M and the maximum velocity u<sub>max</sub> are emphasized as important new parameters. Many flow properties can be expressed in terms of M. Knowledge of u<sub>max</sub> is equivalent to knowing the range of flow velocity in a channel cross section, an important statistical parameter, which along with the mean velocity can completely describe the probability-density function of flow velocity and, hence, the velocity distribution and other related flow properties.

In particular, a realized agreement in each period generates information that changes the underlying information structure in the economy. Since the private core (value) depends on the distribution of information across individuals, when agents learn some new information a realized agreement may no longer be in the private core (value) for the new information structure that arises. We define a 'limit full information' economy and address the following issues; (i) Given a sequence x<sup>t</sup> of approximate private core (value) allocations in each period, there is a subsequence that converges to a private core (value) x<sup>*</sup> allocation for the limit full information economy. (ii) Private core (value) allocations x<sup>*</sup> in the limit full information economy, can be approximated by a sequence x<sub>e</sub><sup>t</sup> of approximate private core (value) allocations in each time period.

374 | 21,560 | Characterization of solvent clusters in a supercritical Lennard-Jones fluid | Journal of Chemical Physics | We have developed a new methodology for characterizing the solvent cluster structures which occur in a pure supercritical fluid in its compressible regime. This methodology takes advantage of the time scale separation which exists between collective-cluster and individual-solvent-atom motions in order to classify atoms according to their "instantaneous" local environments. The resultant picture is of a fluid having density inhomogeneities on a mesoscopic length scale - i.e., clusters and cavities. Calculation of partial radial distribution functions shows that atoms residing in different density domains have very different equilibrium structural properties, information which is not available from the usual total radial distribution function. For example, for a 2-dimensional Lennard-Jones fluid at a reduced temperature T<sub>r</sub> = 1.06 the nearest neighbor coordination number in a high density domain is 4.2, whereas in a low density domain it is only 1.0. We have also found that, for such clustering fluids that in a finite volume system there is an ensemble independent [within terms of (1/N)], nonstructural long-range correlation which arises from an excluded volume effect. This long range correlation enables us to determine the average domain size, volume fraction and density for both the high and low density domains. © 1996 American Institute of Physics. | ["Martinez H.L.", "Ravi R.", "Tucker S.C."] | ["56761577100", "7102356024", "57195387130"] | 1,996 | 40 | [] | 10.1063/1.470762 | Article | English | [{"id": "60014439", "name": "Department of Chemistry, University of California, Davis, CA 95616, United States", "fullName": "Department of Chemistry, University of California", "reference": "a", "fullAddress": "Davis, CA 95616, United States", "departmentId": "112836098"}] |

379 | 21,931 | The Joint Estimation of Signal and Noise from the Sum Envelope | IEEE Transactions on Information Theory | The separate estimation of carrier strength and of narrowband additive noise strength from N envelope samples is considered. The mathematical problem is one of the joint estimation of the two parameters in the Rice probability-density function. The estimation is useful, for example, in the radar analysis of targets containing both specular and distributed components. In the mathematical analysis, theoretical Cramér-Rao lower bounds on the standard deviation in unbiased estimation are first determined. Estimation procedures based upon the method of maximum likelihood and two simple methods of moments are then developed. An error analysis for each procedure is performed by Monte Carlo simulation. For the purpose of comparison, two direct averaging methods are also analyzed. Results are extended to the case where an additional noise is also present, but with known strength. It is also shown that the time average of a slowly-varying carrier strength can be estimated despite the presence of noise. © 1967, IEEE.

384 | 22,357 | Bounded controls in distributed-parameter systems | Journal of Applied Mathematics and Mechanics | Control systems with distributed parameters, described by partial differential equations, solvable with respect to the first or second time derivative, are considered. The controls on the right-hand sides of the equations are assumed to be bounded in absolute magnitude. A control method is proposed which brings the controlled system into the null state in a finite time. The proposed approach is based on decomposing the system and applying the time-optimal control for each mode of motion obtained by Fourier-expanding the solution. Estimates for the duration of the control process are obtained. Sufficient conditions for the problem to be solvable are given. Examples are presented. © 1993. | ["Chernous'ko F.L."] | ["7005396393"] | 1,992 | 29 | [] | 10.1016/0021-8928(92)90057-F | Article | English | [{"id": null, "name": "MoscowUSSR", "fullName": null, "reference": "a", "fullAddress": null, "departmentId": null}] |
385 | 22,420 | Multiperiod security markets with differential information. Martingales and resolution times | Journal of Mathematical Economics | We model multiperiod securities markets with differential information. A price system that admits no free lunches is related to martingales when agents have rational expectations. We introduce the concept of resolution time, and show that a better informed agent and a less informed agent must agree on the resolution times of commonly marketed events if they have rational expectations and if there are no free lunches. It then follows that if all elementary events are marketed for a less informed agent then any price system that admits no free lunches to a better informed agent must eliminate any private information asymmetry between the two. We provide an example of a dynamically fully revealing price system that is arbitrage free and yields elementarily complete markets. © 1986. | ["Duffie D.", "Huang C.-f."] | ["6701468567", "23113692400"] | 1,986 | 61 | [] | 10.1016/0304-4068(86)90017-0 | Article | English | [{"id": "60012708", "name": "Stanford University, Stanford, CA 94305, United States", "fullName": "Stanford University", "reference": "a", "fullAddress": "Stanford, CA 94305, United States", "departmentId": null}, {"id": "60022195", "name": "Massachusetts Institute of Technology, Cambridge, MA 02139, United States", "fullName": "Massachusetts Institute of Technology", "reference": "b", "fullAddress": "Cambridge, MA 02139, United States", "departmentId": null}] |

Examples of rigid-link models, and atomic matrix cellular models employing a Lennard-Jones potential, are included. Attention is paid to criteria for the appearance of homogeneous, localized but distributed, and thoroughly-localized solutions. For the atomic models, generalized coordinates that exploit local and global symmetries of unlinked cells are introduced in a block diagonalization context, to clarify the bifurcation structure. A discretized Lagrangian formulation is introduced to untangle the paths for weakly-linked cells. © 1992. | ["Kiyohiro I.", "Providência P.", "Hunt G.W."] | ["7404891398", "24313141800", "7202673972"] | 1,993 | 8 | [] | 10.1016/0020-7683(93)90173-5 | Article | English | [{"id": "60018352", "name": "Department of Civil Engineering, Nagaoka University of Technology, Nagaoka, Niigata, 940-21, Japan", "fullName": "Department of Civil Engineering, Nagaoka University of Technology", "reference": "a", "fullAddress": "Nagaoka, Niigata, 940-21, Japan", "departmentId": "100263870"}, {"id": "60020985", "name": "Department of Civil Engineering, Universidade de Coimbra, Portugal", "fullName": "Department of Civil Engineering, Universidade de Coimbra", "reference": "b", "fullAddress": "Portugal", "departmentId": null}, {"id": "60015150", "name": "Department of Civil Engineering, Imperial College of Science, Technology and Medicine, London, SW7 2BU, United Kingdom", "fullName": "Department of Civil Engineering, Imperial College of Science, Technology and Medicine", "reference": "c", "fullAddress": "London, SW7 2BU, United Kingdom", "departmentId": "103779505"}] |

391 | 22,653 | A generalized neuronal activation function derived from ion-channel characteristics | Network: Computation in Neural Systems | An abstract model neuron, simple enough to be used in analytical studies of neural networks, is defined. It incorporates neuronal adaptation, i.e. the coupling between neuronal activity and excitability, which can control the complexity of neural network dynamics. A generalized neuronal activation function is defined as the output activity, i.e. The firing rate of action potentials, as a function of an input and an excitability variable. For a biological neuron, the intracellular concentration of Ca ions is shown to be a useful excitability variable. The principal features of the generalized activation function are derived by means of a multicompartment model neuron with ionic currents described by Hodgkin-Huxley-type equations. As a relevant neuron type for investigations of cortical associative memory, a neocortical pyramidal cell of the regularly-spiking type is selected. An approximate analytical consideration suggests a simple form of independent variable of the generalized activation function. The complete numerical treatment verifies this form and displays a threshold character of the activation function. The derivation thereby pmvides an interpretation of dynamic threshold models of neuronal adaptation in terms of ionic mechanism. The threshold with respect to the input has well-defined dynamics directly given by the intracellular Ca dynamics. A comparison of the response of the Hodgkin-Huxley-type and reduced-model neumns to a varying input variable indicates that the reduced model is a usefui approximation even for the detailed behaviour of the firing rate. The generalized activation function also accounts for the dependence on neuromodnlation via an adaptability parameter. An absmt model neural network of units thus defined has the capacity to describe complex network dynamics and the simplicity to allow elucidation of mechanisms and applications to large-scale systems. © 1995 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted. | ["Cartling B."] | ["6701366379"] | 1,995 | 11 | [] | 10.1088/0954-898X_6_3_005 | Article | English | [{"id": "60002014", "name": "Department of Theoretical Physics, The Royal Institute of Technology, S-100 44, Stockholm, Sweden", "fullName": "Department of Theoretical Physics, The Royal Institute of Technology", "reference": "a", "fullAddress": "S-100 44, Stockholm, Sweden", "departmentId": "110908102"}] |
392 | 22,678 | The intertemporal dimension of neoclassical production theory | Journal of Economic Surveys | The aim of this survey paper is to provide a guide to the literature on optimal dynamic factor demands to the non-specialist reader interested in applied work. We start with the distinction between variable and quasi-fixed factors of production and use these to characterize the firm's temporary equilibrium. We then review the optimal intertemporal behaviour of the firm, using the notion of adjustment costs as a means to solve the firm's optimization problem. This process gives rise to a system of interrelated dynamic factor demands in a flexible accelerator format. Theoretical difficulties and empirical limitations of this model are discussed. This fact leads us to review the theory of intertemporal duality. We next analyze the issue of expectations in this class of dynamic models. A section reviewing the empirical work on dynamic factor demands follows, after which we offer some concluding remarks. | ["Galeotti M."] | ["16419724600"] | 1,996 | 11 | ["Dynamic factor demands", "Flexible accelerator", "Intertemporal duality", "Intertemporal firm behaviour"] | 10.1111/j.1467-6419.1996.tb00019.x | Article | English | [{"id": "60005254", "name": "Univ. degli Studi di Bergamo", "fullName": "Univ. degli Studi di Bergamo", "reference": "a", "fullAddress": null, "departmentId": null}] |

394 | 22,768 | Integrated product concepts development and evaluation | International Journal of Computer Integrated Manufacturing | The traditional method of developing products suffers from a lack of information of the later stages of the development process when the early decisions are made. This would probably lead to staggering losses in lead time and project resources. This problem could be avoided if the development team makes the early design decisions with sufficient considerations on other aspects such as manufacturing processes, tool making, etc. This paper aims to present the authors' recent research results in the establishment of a decision making framework at the product concept development process. According to the framework and using the knowledge based system methodology, an integrated product concepts development and evaluation system has been developed for plastic injection moulding part. The system is capable of generating the material selection, injection mould design features, injection mould making process plan, production moulding plan, estimated mould making lead time, and cost estimates of injection mould and production moulding at the product concept stage. © 1999 Taylor & Francis Ltd. | ["Chin K.-S.", "Wong T.N."] | ["7202995439", "55301015400"] | 1,999 | 9 | [] | 10.1080/095119299130416 | Article | English | [{"id": "60013983", "name": "Department of Manufacturing Engineering and Engineering Management, City University of Hong Kong, Tat Chee Avenue, Hong Kong", "fullName": "Department of Manufacturing Engineering and Engineering Management, City University of Hong Kong", "reference": "a", "fullAddress": "Tat Chee Avenue, Hong Kong", "departmentId": "103724838"}, {"id": null, "name": "Department of Industrial and Manufacturing System Engineering, Unive rsity of Hong Kong, Pokfulam, Taiwan", "fullName": "Department of Industrial and Manufacturing System Engineering, Unive rsity of Hong Kong", "reference": "b", "fullAddress": "Pokfulam, Taiwan", "departmentId": null}] |

400 | 23,168 | In Situ Characterization of Laser Diodes from Wide-Band Electrical Noise Measurements | Journal of Lightwave Technology | The wide-band electrical noise characteristics of 0.8-, 1.3-, and l.5-μm laser diodes have been studied theoretically and for the first time also experimentally. The electrical noise is related to the optical intensity noise behavior, and can therefore be used for in situ measurements and characterization of laser diodes. Since the measurements are performed without any optical components, undesired optical feedback is eliminated. The results show that several important laser parameters and characteristics can be extracted from purely electrical noise measurements. Among these are the relaxation frequency, the threshold current, the emission linewidth, optical feedback properties, and longitudinal mode hopping behavior. Good agreement between the noise theory and the electrical noise measurements has been obtained. An expression for obtaining both the spectral linewidth and lineshape from electrical noise measurements is also derived. © 1986 IEEE | ["Andrekson A.", "Andersson P.", "Alping A.", "Eng S.T."] | ["56838367600", "23020653800", "6701408867", "7006280657"] | 1,986 | 21 | [] | 10.1109/JLT.1986.1074803 | Article | English | [{"id": "60000990", "name": "Department of Electrical Measurements, Chalmers University of Technology, 412 96 Gothenburg, Sweden", "fullName": "Department of Electrical Measurements, Chalmers University of Technology", "reference": "a", "fullAddress": "412 96 Gothenburg, Sweden", "departmentId": "103097565"}] |
