    "Bernoulli" levitation is the basis of many popular counter-intuitive physics demonstrations. However, few of these lend themselves to a quantitative description without recourse to computational fluid dynamics. Levitation of a flat plate is the exception, and we present here a straightforward analysis which illustrates several principles of fluid mechanics in a pedagogically useful way.

    One of the most fun demonstrations in a freshman mechanics class is the levitation of a ball in a steady air stream even when the jet is directed at an angle. This and other demonstrations are often used to argue for the validity of Bernoulli's principle. As cautioned by some authors, however, it is important to avoid making sweeping statements…

  7. Bernoulli Suction Effect on Soap Bubble Blowing?

    Science.gov (United States)

    Davidson, John; Ryu, Sangjin

    2015-11-01

    As a model system for thin-film bubble with two gas-liquid interfaces, we experimentally investigated the pinch-off of soap bubble blowing. Using the lab-built bubble blower and high-speed videography, we have found that the scaling law exponent of soap bubble pinch-off is 2/3, which is similar to that of soap film bridge. Because air flowed through the decreasing neck of soap film tube, we studied possible Bernoulli suction effect on soap bubble pinch-off by evaluating the Reynolds number of airflow. Image processing was utilized to calculate approximate volume of growing soap film tube and the volume flow rate of the airflow, and the Reynolds number was estimated to be 800-3200. This result suggests that soap bubbling may involve the Bernoulli suction effect.

  8. Bernoulli numbers and zeta functions

    2014-01-01

    Two major subjects are treated in this book. The main one is the theory of Bernoulli numbers and the other is the theory of zeta functions. Historically, Bernoulli numbers were introduced to give formulas for the sums of powers of consecutive integers. The real reason that they are indispensable for number theory, however, lies in the fact that special values of the Riemann zeta function can be written by using Bernoulli numbers. This leads to more advanced topics, a number of which are treated in this book: Historical remarks on Bernoulli numbers and the formula for the sum of powers of consecutive integers; a formula for Bernoulli numbers by Stirling numbers; the Clausen–von Staudt theorem on the denominators of Bernoulli numbers; Kummer's congruence between Bernoulli numbers and a related theory of p-adic measures; the Euler–Maclaurin summation formula; the functional equation of the Riemann zeta function and the Dirichlet L functions, and their special values at suitable integers; various formulas of ...

  9. Generalized Bernoulli-Hurwitz numbers and the universal Bernoulli numbers

    International Nuclear Information System (INIS)

    The three fundamental properties of the Bernoulli numbers, namely, the von Staudt-Clausen theorem, von Staudt's second theorem, and Kummer's original congruence, are generalized to new numbers that we call generalized Bernoulli-Hurwitz numbers. These are coefficients in the power series expansion of a higher-genus algebraic function with respect to a suitable variable. Our generalization differs strongly from previous works. Indeed, the order of the power of the modulus prime in our Kummer-type congruences is exactly the same as in the trigonometric function case (namely, Kummer's own congruence for the original Bernoulli numbers), and as in the elliptic function case (namely, H. Lang's extension for the Hurwitz numbers). However, in other past results on higher-genus algebraic functions, the modulus was at most half of its value in these classical cases. This contrast is clarified by investigating the analogue of the three properties above for the universal Bernoulli numbers. Bibliography: 34 titles.

  15. Bernoulli Variational Problem and Beyond

    KAUST Repository

    Lorz, Alexander

    2013-12-17

    The question of \\'cutting the tail\\' of the solution of an elliptic equation arises naturally in several contexts and leads to a singular perturbation problem under the form of a strong cut-off. We consider both the PDE with a drift and the symmetric case where a variational problem can be stated. It is known that, in both cases, the same critical scale arises for the size of the singular perturbation. More interesting is that in both cases another critical parameter (of order one) arises that decides when the limiting behaviour is non-degenerate. We study both theoretically and numerically the values of this critical parameter and, in the symmetric case, ask if the variational solution leads to the same value as for the maximal solution of the PDE. Finally we propose a weak formulation of the limiting Bernoulli problem which incorporates both Dirichlet and Neumann boundary condition. © 2013 Springer-Verlag Berlin Heidelberg.

  1. Sum of Bernoulli Mixtures: Beyond Conditional Independence

    Directory of Open Access Journals (Sweden)

    Taehan Bae

    2014-01-01

    Full Text Available We consider the distribution of the sum of Bernoulli mixtures under a general dependence structure. The level of dependence is measured in terms of a limiting conditional correlation between two of the Bernoulli random variables. The conditioning event is that the mixing random variable is larger than a threshold and the limit is with respect to the threshold tending to one. The large-sample distribution of the empirical frequency and its use in approximating the risk measures, value at risk and conditional tail expectation, are presented for a new class of models which we call double mixtures. Several illustrative examples with a Beta mixing distribution, are given. As well, some data from the area of credit risk are fit with the models, and comparisons are made between the new models and also the classical Beta-binomial model.

  2. Shape optimisation of an underwater Bernoulli gripper

    Science.gov (United States)

    Flint, Tim; Sellier, Mathieu

    2015-11-01

    In this work, we are interested in maximising the suction produced by an underwater Bernoulli gripper. Bernoulli grippers work by exploiting low pressure regions caused by the acceleration of a working fluid through a narrow channel, between the gripper and a surface, to provide a suction force. This mechanism allows for non-contact adhesion to various surfaces and may be used to hold a robot to the hull of a ship while it inspects welds for example. A Bernoulli type pressure analysis was used to model the system with a Darcy friction factor approximation to include the effects of frictional losses. The analysis involved a constrained optimisation in order to avoid cavitation within the mechanism which would result in decreased performance and damage to surfaces. A sensitivity based method and gradient descent approach was used to find the optimum shape of a discretised surface. The model's accuracy has been quantified against finite volume computational fluid dynamics simulation (ANSYS CFX) using the k- ω SST turbulence model. Preliminary results indicate significant improvement in suction force when compared to a simple geometry by retaining a pressure just above that at which cavitation would occur over as much surface area as possible.

  3. Bernoulli's Principle Applied to Brain Fluids: Intracranial Pressure Does Not Drive Cerebral Perfusion or CSF Flow.

    Science.gov (United States)

    Schmidt, Eric; Ros, Maxime; Moyse, Emmanuel; Lorthois, Sylvie; Swider, Pascal

    2016-01-01

    In line with the first law of thermodynamics, Bernoulli's principle states that the total energy in a fluid is the same at all points. We applied Bernoulli's principle to understand the relationship between intracranial pressure (ICP) and intracranial fluids. We analyzed simple fluid physics along a tube to describe the interplay between pressure and velocity. Bernoulli's equation demonstrates that a fluid does not flow along a gradient of pressure or velocity; a fluid flows along a gradient of energy from a high-energy region to a low-energy region. A fluid can even flow against a pressure gradient or a velocity gradient. Pressure and velocity represent part of the total energy. Cerebral blood perfusion is not driven by pressure but by energy: the blood flows from high-energy to lower-energy regions. Hydrocephalus is related to increased cerebrospinal fluid (CSF) resistance (i.e., energy transfer) at various points. Identification of the energy transfer within the CSF circuit is important in understanding and treating CSF-related disorders. Bernoulli's principle is not an abstract concept far from clinical practice. We should be aware that pressure is easy to measure, but it does not induce resumption of fluid flow. Even at the bedside, energy is the key to understanding ICP and fluid dynamics. PMID:27165887

  4. Bernoulli Numbers: from Ada Lovelace to the Debye Functions

    Jacob Bernoulli owes his fame for the numerous contributions to calculus and for his discoveries in the field of probability. Here we will discuss one of his contributions to the theory of numbers, the Bernoulli numbers. They were proposed as a case study by Ada Lovelace in her analysis of Menabrea's report on Babbage Analytical Engine. It is probable that it was this Lovelace's work, that inspired Hans Thirring in using the Bernoulli numbers in the calculus of the Debye functions.

  5. Dynamic Euler-Bernoulli Beam Equation: Classification and Reductions

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available We study a dynamic fourth-order Euler-Bernoulli partial differential equation having a constant elastic modulus and area moment of inertia, a variable lineal mass density g(x, and the applied load denoted by f(u, a function of transverse displacement u(t,x. The complete Lie group classification is obtained for different forms of the variable lineal mass density g(x and applied load f(u. The equivalence transformations are constructed to simplify the determining equations for the symmetries. The principal algebra is one-dimensional and it extends to two- and three-dimensional algebras for an arbitrary applied load, general power-law, exponential, and log type of applied loads for different forms of g(x. For the linear applied load case, we obtain an infinite-dimensional Lie algebra. We recover the Lie symmetry classification results discussed in the literature when g(x is constant with variable applied load f(u. For the general power-law and exponential case the group invariant solutions are derived. The similarity transformations reduce the fourth-order partial differential equation to a fourth-order ordinary differential equation. For the power-law applied load case a compatible initial-boundary value problem for the clamped and free end beam cases is formulated. We deduce the fourth-order ordinary differential equation with appropriate initial and boundary conditions.

    2008-01-01

    Full Text Available This paper presents a theoretical background and an example of extending the Euler-Bernoulli equation from several aspects. Euler-Bernoulli equation (based on the known laws of dynamics should be supplemented with all the forces that are participating in the formation of the bending moment of the considered mode. The stiffness matrix is a full matrix. Damping is an omnipresent elasticity characteristic of real systems, so that it is naturally included in the Euler-Bernoulli equation. It is shown that Daniel Bernoulli's particular integral is just one component of the total elastic deformation of the tip of any mode to which we have to add a component of the elastic deformation of a stationary regime in accordance with the complexity requirements of motion of an elastic robot system. The elastic line equation mode of link of a complex elastic robot system is defined based on the so-called 'Euler-Bernoulli Approach' (EBA. It is shown that the equation of equilibrium of all forces present at mode tip point ('Lumped-mass approach' (LMA follows directly from the elastic line equation for specified boundary conditions. This, in turn, proves the essential relationship between LMA and EBA approaches. In the defined mathematical model of a robotic system with multiple DOF (degree of freedom in the presence of the second mode, the phenomenon of elasticity of both links and joints are considered simultaneously with the presence of the environment dynamics - all based on the previously presented theoretical premises. Simulation results are presented. .

  8. Bernoulli measure of complex admissible kneading sequences

    CERN Document Server

    Bruin, Henk

    2012-01-01

    Iterated quadratic polynomials give rise to a rich collection of different dynamical systems that are parametrized by a simple complex parameter $c$. The different dynamical features are encoded by the \\emph{kneading sequence} which is an infinite sequence over $\\{0,\\1\\}$. Not every such sequence actually occurs in complex dynamics. The set of admissible kneading sequences was described by Milnor and Thurston for real quadratic polynomials, and by the authors in the complex case. We prove that the set of admissible kneading sequences has positive Bernoulli measure within the set of sequences over $\\{0,\\1\\}$.

  9. Bernoulli equation and flow over a mountain

    Science.gov (United States)

    Sun, Wen-Yih; Sun, Oliver M.

    2015-12-01

    The Bernoulli equation is applied to an air parcel which originates at a low level at the inflow region, climbs adiabatically over a mountain with an increase in velocity, then descends on the lee side and forms a strong downslope wind. The parcel departs from hydrostatic equilibrium during its vertical motion. The air parcel can be noticeably cooler than the temperature calculated from adiabatic lapse rate, which allows part of enthalpy to be converted to kinetic energy and produces a stronger wind at mountain peak and a severe downslope wind on the lee side. It was found that the hydrostatic assumption tends to suppress the conversion from enthalpy to kinetic energy. It is also shown that the Froude number defined in the atmosphere is equal to the ratio of kinetic energy to the potential energy, same as in Boussinesq fluid. But in the atmosphere, the Froude number cannot be used to determine whether a parcel can move over a mountain or not, unless the vertical motion is weak and the system is near hydrostatic equilibrium. Numerical simulations confirm that except in highly turbulent areas, the potential temperature and Bernoulli function are almost conserved along the streamline, as well as the change of kinetic energy comes from the change of enthalpy instead of potential energy.

    Full Text Available Purpose: We consider a discrete-time Geo/G/1 retrial queue where the retrial time follows a general distribution, the server subject to Bernoulli vacation policy and the customer has preemptive resume priority, Bernoulli feedback strategy. The main purpose of this paper is to derive the generating functions of the stationary distribution of the system state, the orbit size and some important performance measures. Design/methodology: Using probability generating function technique, some valuable and interesting performance measures of the system are obtained. We also investigate two stochastic decomposition laws and present some numerical results. Findings: We obtain the probability generating functions of the system state distribution as well as those of the orbit size and the system size distributions. We also obtain some analytical expressions for various performance measures such as idle and busy probabilities, mean orbit and system sizes. Originality/value: The analysis of discrete-time retrial queues with Bernoulli vacation, preemptive resume and feedback customers is interesting and to the best of our knowledge, no other scientific journal paper has dealt with this question. This fact gives the reason why efforts should be taken to plug this gap.

    Full Text Available In this paper, the relationship between the original Euler-Bernoulli's rod equation and contemporary knowledge is established. The solution which Daniel Bernoulli defined for the simplest conditions is essentially the solution of 'direct kinematics'. For this reason, special attention is devoted to dynamics and kinematics of elastic mechanisms configuration. The Euler-Bernoulli equation and its solution (used in literature for a long time should be expanded according to the requirements of the mechanisms motion complexity. The elastic deformation is a dynamic value that depends on the total mechanism movements dynamics. Mathematical model of the actuators comprises also elasticity forces.

It is shown that due to electron degeneracy, a nontrivial Beltrami–Bernoulli equilibrium state is possible even for a zero temperature plasma. These states are, conceptually, studied to show the existence of new energy transformation pathways converting, for instance, the degeneracy energy into fluid kinetic energy. Such states may be of relevance to compact astrophysical objects like white dwarfs, neutron stars, etc.

    Wang, Caishi; Ye, Xiaojuan

    2016-05-01

    Quantum Bernoulli noises are the family of annihilation and creation operators acting on Bernoulli functionals, which satisfy a canonical anti-commutation relation in equal time. In this paper, we first present some new results concerning quantum Bernoulli noises, which themselves are interesting. Then, based on these new results, we construct a time-dependent quantum walk with infinitely many degrees of freedom. We prove that the walk has a unitary representation and hence belongs to the category of the so-called unitary quantum walks. We examine its distribution property at the vacuum initial state and some other initial states and find that it has the same limit distribution as the classical random walk, which contrasts sharply with the case of the usual quantum walks with finite degrees of freedom.

    Lecture Demonstration professionals have recently taken a closer look at demonstrations that were traditionally labeled ``Bernoulli Demonstrations'' in most textbooks. This examination has shown that in most cases the Coanda Effect, Magnus Effect, and Entrainment may be better explanations for most of these classic demonstrations. A discussion of other similarly classic demonstrations and some of their problems or misconceptions will also be presented.

  11. On nonlocal characteristics of curved inhomogeneous Euler-Bernoulli nanobeams under different temperature distributions

    Science.gov (United States)

    Ebrahimi, Farzad; Barati, Mohammad Reza

    2016-10-01

    In this paper, thermo-mechanical buckling analysis of curved functionally graded (FG) nanobeams is carried out via an analytical solution method. Curved FG nanobeam is subjected to uniform, linear and nonlinear temperature distributions across the thickness. Three kinds of boundary condition namely, simply supported-simply supported, simply supported-clamped and clamped-clamped are investigated. Thermo-elastic properties of curved FG beam change in radial direction according to the power-law model. Nonlocal elasticity theory is adopted to capture the size effects. Nonlocal governing equations of curved FG nanobeam are obtained from Hamilton's principle based on Euler-Bernoulli beam model. Finally, the influences of thermal loadings, nonlocal parameter, opening angle, material composition, slenderness ratio and boundary conditions on the thermal buckling behavior of nanosize curved FG beams are explored.

    We construct a modified Bernoulli iteration method for solving the quadratic matrix equation AX2+BX+C=0,where A,B and C are square matrices.This method is motivated from the Gauss-Seidel iteration for solving linear systems and the ShermanMorrison-Woodbury formula for updating matrices.Under suitable conditions, we prove the local linear convergence of the Dew method.An algorithm is presented to find the solution of the quadratic matrix equation and some numerical results are given to show the feasibility and the effectiveness of the algorithm.In addition,we also describe and analyze the block version of the modified Bernoulli iteration method.

    2011-01-01

    Full Text Available In this work we prove that the exact internal observability for theEuler-Bernoulli equation is robust with respect to a class of linear perturbations. Our results yield,in particular,that for rectangular domains we have the exact observability in an arbitrarily small time and with an arbitrarily small observation region. The usual method of tackling lower order terms,using Carleman estimates, cannot be applied in this context. More precisely, it is not known if Carleman estimates hold for the evolution Euler-Bernoulli equation with arbitrarily small observation region. Therefore we use a method combining frequency domain techniques,a compactness-uniqueness argument and a Carleman estimate for elliptic problems.

  14. On the number of empty boxes in the Bernoulli sieve II

    CERN Document Server

    Iksanov, Alexander

    2011-01-01

    The Bernoulli sieve is the infinite "balls-in-boxes" occupancy scheme with random frequencies $P_k=W_1... W_{k-1}(1-W_k)$, where $(W_k)_{k\\in\\mn}$ are independent copies of a random variable $W$ taking values in $(0,1)$. Assuming that the number of balls equals $n$, let $L_n$ denote the number of empty boxes within the occupancy range. In the paper we investigate convergence in distribution of $L_n$ in the two cases which remained open after the previous studies. In particular, provided that $\\me |\\log W|=\\me |\\log (1-W)|=\\infty$ and that the law of $W$ assigns comparable masses to the neighborhoods of 0 and 1, it is shown that $L_n$ weakly converges to a geometric law. This result is derived as a corollary to a more general assertion concerning the number of zero decrements of nonincreasing Markov chains. In the case that $\\me |\\log W|<\\infty$ and $\\me |\\log (1-W)|=\\infty$ we derive several further possible modes of convergence in distribution of $L_n$. It turns out that the class of possible limiting law...

  15. CHARACTERIZATION OF MARKOV-BERNOULLI GEOMETRIC DISTRIBUTION RELATED TO RANDOM SUMS

    Directory of Open Access Journals (Sweden)

    Mohamed Gharib

    2014-01-01

    Full Text Available The Markov-Bernoulli geometric distribution is obtained when a generalization, as a Markov process, of the independent Bernoulli sequence of random variables is introduced by considering the success probability changes with respect to the Markov chain. The resulting model is called the Markov- Bernoulli model and it has a wide variety of application fields. In this study, some characterizations are given concerning the Markov-Bernoulli geometric distribution as the distribution of the summation index of independent randomly truncated non-negative integer valued random variables. The achieved results generalize the corresponding characterizations concerning the usual geometric distribution.

    2006-01-01

    Full Text Available Lean buffering is the smallest buffer capacity necessary to ensure the desired production rate of a manufacturing system. In this paper, analytical methods for selecting lean buffering in serial production lines are developed under the assumption that the machines obey the Bernoulli reliability model. Both closed-form expressions and recursive approaches are investigated. The cases of identical and nonidentical machines are analyzed. Results obtained can be useful for production line designers and production managers to maintain the required production rate with the smallest possible inventories.

    Mathematical modeling and analysis of spatio-temporal chaotic dynamics of flexible simple and curved Euler-Bernoulli beams are carried out. The Kármán-type geometric non-linearity is considered. Algorithms reducing partial differential equations which govern the dynamics of studied objects and associated boundary value problems are reduced to the Cauchy problem through both Finite Difference Method with the approximation of O(c(2)) and Finite Element Method. The obtained Cauchy problem is solved via the fourth and sixth-order Runge-Kutta methods. Validity and reliability of the results are rigorously discussed. Analysis of the chaotic dynamics of flexible Euler-Bernoulli beams for a series of boundary conditions is carried out with the help of the qualitative theory of differential equations. We analyze time histories, phase and modal portraits, autocorrelation functions, the Poincaré and pseudo-Poincaré maps, signs of the first four Lyapunov exponents, as well as the compression factor of the phase volume of an attractor. A novel scenario of transition from periodicity to chaos is obtained, and a transition from chaos to hyper-chaos is illustrated. In particular, we study and explain the phenomenon of transition from symmetric to asymmetric vibrations. Vibration-type charts are given regarding two control parameters: amplitude q(0) and frequency ω(p) of the uniformly distributed periodic excitation. Furthermore, we detected and illustrated how the so called temporal-space chaos is developed following the transition from regular to chaotic system dynamics.

    Full Text Available In this paper, we introduce a new class of generalized  polynomials associated with  the modified Milne-Thomson's polynomials Φ_{n}^{(α}(x,ν of degree n and order α introduced by  Derre and Simsek.The concepts of Bernoulli numbers B_n, Bernoulli polynomials  B_n(x, generalized Bernoulli numbers B_n(a,b, generalized Bernoulli polynomials  B_n(x;a,b,c of Luo et al, Hermite-Bernoulli polynomials  {_HB}_n(x,y of Dattoli et al and {_HB}_n^{(α} (x,y of Pathan  are generalized to the one   {_HB}_n^{(α}(x,y,a,b,c which is called  the generalized  polynomial depending on three positive real parameters. Numerous properties of these polynomials and some relationships between B_n, B_n(x, B_n(a,b, B_n(x;a,b,c and {}_HB_n^{(α}(x,y;a,b,c  are established. Some implicit summation formulae and general symmetry identities are derived by using different analytical means and applying generating functions. These results extend some known summations and identities of generalized Bernoulli numbers and polynomials

    We consider group measure space II$_1$ factors $M=L^{\\infty}(X)\\rtimes\\Gamma$ arising from Bernoulli actions of ICC property (T) groups $\\Gamma$ (more generally, of groups $\\Gamma$ containing an infinite normal subgroup with relative property (T)) and prove a rigidity result for *--homomorphisms $\\theta:M\\to M\\bar{\\otimes}M$. We deduce that the action $\\Gamma\\curvearrowright X$ is W$^*$--superrigid. This means that if $\\Lambda\\curvearrowright Y$ is {\\bf any other} free, ergodic, measure preserving action such that the factors $M=L^{\\infty}(X)\\rtimes\\Gamma$ and $L^{\\infty}(Y)\\rtimes\\Lambda$ are isomorphic, then the actions $\\Gamma\\curvearrowright X$ and $\\Lambda\\curvearrowright Y$ must be conjugate. Moreover, we show that if $p\\in M\\setminus\\{1\\}$ is a projection, then $pMp$ does not admit a group measure space decomposition nor a group von Neumann algebra decomposition (the latter under the additional assumption that $\\Gamma$ is torsion free). We also prove a rigidity result for *--homomorphisms $\\theta:M\\to ...

    The target of this paper is to present an exhaustive study on the small scale effect on vibrational behavior of a rotary tapered axially functionally graded (AFG) microbeam on the basis of Timoshenko and Euler-Bernoulli beam and modified couple stress theories. The variation of the material properties and cross section along the longitudinal direction of the microbeam are taken into consideration as a linear function. Hamilton's principle is used to derive the equations for cantilever and propped cantilever boundary conditions and the generalized differential quadrature method (GDQM) is employed to solve the equations. By parametric study, the effects of small-scale parameter, rates of cross section change of the microbeam and angular velocity on the fundamental and second frequencies of the microbeam are studied. Also, comparison between the frequencies of Timoshenko and Euler-Bernoulli microbeams are presented. The results can be used in many applications such as micro-robots and biomedical microsystems.

    Full Text Available In the present paper, an analytical method is developed to investigate the effects of added mass on natural frequencies and mode shapes of Euler-Bernoulli beams carrying concentrated masse at arbitrary position submerged in a fluid media. A fixed-fixed beams carrying concentrated masse vibrating in a fluid is modeled using the Bernoulli-Euler equation for the beams and the acoustic equation for the fluid. The symbolic software Mathematica is used in order to find the coupled vibration frequencies of a beams with two portions. The frequency equation is deduced and analytically solved. The finite element method using Comsol Multiphysics software results are compared with present method for validation and an acceptable match between them were obtained. In the eigenanalysis, the frequency equation is generated by satisfying all boundary conditions. It is shown that the present formulation is an appropriate and new approach to tackle the problem with good accuracy.

  2. Dynamic probability control limits for risk-adjusted Bernoulli CUSUM charts.

    Science.gov (United States)

    Zhang, Xiang; Woodall, William H

    2015-11-10

    The risk-adjusted Bernoulli cumulative sum (CUSUM) chart developed by Steiner et al. (2000) is an increasingly popular tool for monitoring clinical and surgical performance. In practice, however, the use of a fixed control limit for the chart leads to a quite variable in-control average run length performance for patient populations with different risk score distributions. To overcome this problem, we determine simulation-based dynamic probability control limits (DPCLs) patient-by-patient for the risk-adjusted Bernoulli CUSUM charts. By maintaining the probability of a false alarm at a constant level conditional on no false alarm for previous observations, our risk-adjusted CUSUM charts with DPCLs have consistent in-control performance at the desired level with approximately geometrically distributed run lengths. Our simulation results demonstrate that our method does not rely on any information or assumptions about the patients' risk distributions. The use of DPCLs for risk-adjusted Bernoulli CUSUM charts allows each chart to be designed for the corresponding particular sequence of patients for a surgeon or hospital.

If $X$ and $Y$ are two independent random variables which have respectively Bernoulli and Gamma distributions, we denote by $\\mu$ the distribution of $X+Y.$ The above problem is equivalent to finding the set of $x>0$ such that $\\mu^{{\\ast}x}$ exists.

    In this article,we study the stabilization problem of a nonuniform Euler-Bernoulli beam with locally distributed feedbacks.Firstly,using the semi-group theory,we establish the well-posedness of the associated closed loop system.Then by proving the uniqueness of the solution of a related ordinary differential equations,we derive the asymptotic stability of the closed loop system. Finally,by means of the piecewise frequency domain multiplier method,we prove that the corresponding closed loop system can be exponentially stabilized by only one of the two distributed feedback controls proposed in this paper.

  5. Sign reversals of the output autocorrelation function for the stochastic Bernoulli-Verhulst equation

    We consider a stochastic Bernoulli-Verhulst equation as a model for population growth processes. The effect of fluctuating environment on the carrying capacity of a population is modeled as colored dichotomous noise. Relying on the composite master equation an explicit expression for the stationary autocorrelation function (ACF) of population sizes is found. On the basis of this expression a nonmonotonic decay of the ACF by increasing lag-time is shown. Moreover, in a certain regime of the noise parameters the ACF demonstrates anticorrelation as well as related sign reversals at some values of the lag-time. The conditions for the appearance of this highly unexpected effect are also discussed.

  7. Modified Bernoulli Equation for Use with Combined Electro-Osmotic and Pressure-Driven Microflows

    CERN Document Server

    Adams, Thomas M

    2012-01-01

    In this paper we present electro-osmotic (EO) flow within a more traditional fluid mechanics framework. Specifically, the modified Bernoulli equation (viz. the energy equation, the mechanical energy equation, the pipe flow equation, etc.) is shown to be applicable to EO flows if an electrical potential energy term is also included. The form of the loss term in the modified Bernoulli equation is unaffected by the presence of an electric field; i.e., the loss term still represents the effect of wall shear stress, which can be represented via a friction factor. We show that that the friction factor for pure EO flow (no applied pressure gradient) varies inversely with the Reynolds number based on the Debeye length of the electric double layer. Expressions for friction factor for combined laminar pressure-driven and EO flow are also given. These are shown to be functions of Reynolds number and geometry, as well as the relative strength of the applied electric field to the applied pressure gradient.

    2014-01-01

    The field of neuromorphic silicon synapse circuits is revisited and a parsimonious mathematical framework able to describe the dynamics of this class of log-domain circuits in the aggregate and in a systematic manner is proposed. Starting from the Bernoulli Cell Formalism (BCF), originally formulated for the modular synthesis and analysis of externally linear, time-invariant logarithmic filters, and by means of the identification of new types of Bernoulli Cell (BC) operators presented here, a generalized formalism (GBCF) is established. The expanded formalism covers two new possible and practical combinations of a MOS transistor (MOST) and a linear capacitor. The corresponding mathematical relations codifying each case are presented and discussed through the tutorial treatment of three well-known transistor-level examples of log-domain neuromorphic silicon synapses. The proposed mathematical tool unifies past analysis approaches of the same circuits under a common theoretical framework. The speed advantage of the proposed mathematical framework as an analysis tool is also demonstrated by a compelling comparative circuit analysis example of high order, where the GBCF and another well-known log-domain circuit analysis method are used for the determination of the input-output transfer function of the high (4(th)) order topology.

  9. A Numerical Method of the Euler-Bernoulli Beam with Optimal Local Kelvin-Voigt Damping

    Full Text Available This paper deals with the numerical approximation problem of the optimal control problem governed by the Euler-Bernoulli beam equation with local Kelvin-Voigt damping, which is a nonlinear coefficient control problem with control constraints. The goal of this problem is to design a control input numerically, which is the damping and distributes locally on a subinterval of the region occupied by the beam, such that the total energy of the beam and the control on a given time period is minimal. We firstly use the finite element method (FEM to obtain a finite-dimensional model based on the original PDE system. Then, using the control parameterization method, we approximate the finite-dimensional problem by a standard optimal parameter selection problem, which is a suboptimal problem and can be solved numerically by nonlinear mathematical programming algorithm. At last, some simulation studies will be presented by the proposed numerical approximation method in this paper, where the damping controls act on different locations of the Euler-Bernoulli beam.

    In an effort to improve the accuracy of force-separation curves obtained from atomic force microscope data, we compare force-separation curves computed using two methods to solve the Euler-Bernoulli equation. A recently introduced method using a direct sequential forward solution, Causal Time-Domain Analysis, is compared against a previously introduced Tikhonov Regularization method. Using the direct solution as a benchmark, it is found that the regularization technique is unable to reproduce accurate curve shapes. Using L-curve analysis and adjusting the regularization parameter, λ, to match either the depth or the full width at half maximum of the force curves, the two techniques are contrasted. Matched depths result in full width at half maxima that are off by an average of 27% and matched full width at half maxima produce depths that are off by an average of 109%.

    2011-01-01

    Full Text Available Structural analysis of axially functionally graded tapered Euler-Bernoulli beams is studied using finite element method. A beam element is proposed which takes advantage of the shape functions of homogeneous uniform beam elements. The effects of varying cross-sectional dimensions and mechanical properties of the functionally graded material are included in the evaluation of structural matrices. This method could be used for beam elements with any distributions of mass density and modulus of elasticity with arbitrarily varying cross-sectional area. Assuming polynomial distributions of modulus of elasticity and mass density, the competency of the element is examined in stability analysis, free longitudinal vibration and free transverse vibration of double tapered beams with different boundary conditions and the convergence rate of the element is then investigated.

    Full Text Available By integrating the cardinality balanced multitarget multi-Bernoulli (CBMeMBer filter with the interacting multiple models (IMM algorithm, an MM-CBMeMBer filter is proposed in this paper for tracking multiple maneuvering targets in clutter. The sequential Monte Carlo (SMC method is used to implement the filter for generic multi-target models and the Gaussian mixture (GM method is used to implement the filter for linear-Gaussian multi-target models. Then, the extended Kalman (EK and unscented Kalman filtering approximations for the GM-MM-CBMeMBer filter to accommodate mildly nonlinear models are described briefly. Simulation results are presented to show the effectiveness of the proposed filter.

  16. Model uncertainty in economic impacts of climate change: Bernoulli versus Lotka Volterra dynamics.

    Science.gov (United States)

    Cooke, Roger M

    2013-01-01

    The dynamic economic behavior in most integrated assessment models linking economic growth to climate change involves a differential equation solved by Jacob Bernoulli in 1695. Using the dynamic integrated climate economy (DICE) model and freezing exogenous variables at initial values, this dynamic is shown to produce implausible projections on a 60-year time frame. If world capital started at US$1, after 60 years the world economy would be indistinguishable from one starting with 10 times the current capitalization. Such behavior points to uncertainty at the level of the fundamental dynamics, and suggests that discussions of discounting, utility, damage functions, and ethics should be conducted within a more general modeling vocabulary. Lotka Volterra dynamics is proposed as an alternative with greater prime facie plausibility. With near universality, economists assume that economic growth will go on forever. Lotka Volterra dynamics alert us to the possibility of collapse.

  17. A biclustering algorithm for binary matrices based on penalized Bernoulli likelihood

    KAUST Repository

    Lee, Seokho

    2013-01-31

    We propose a new biclustering method for binary data matrices using the maximum penalized Bernoulli likelihood estimation. Our method applies a multi-layer model defined on the logits of the success probabilities, where each layer represents a simple bicluster structure and the combination of multiple layers is able to reveal complicated, multiple biclusters. The method allows for non-pure biclusters, and can simultaneously identify the 1-prevalent blocks and 0-prevalent blocks. A computationally efficient algorithm is developed and guidelines are provided for specifying the tuning parameters, including initial values of model parameters, the number of layers, and the penalty parameters. Missing-data imputation can be handled in the EM framework. The method is tested using synthetic and real datasets and shows good performance. © 2013 Springer Science+Business Media New York.

  18. Hydraulic concentration of magnetic fields in the solar photosphere. II - Bernoulli effect

    Science.gov (United States)

    Parker, E. N.

    1974-01-01

    The magnetic filaments in the solar photosphere are subject to vigorous kneading and massaging by the convective turbulence at, and beneath, the visible surface. It is shown that the Bernoulli effect of the consequent surging of fluid up and down along the filaments is a major factor in concentrating the magnetic pressure of the filament (the mean square field). The mean field is also increased if the phase velocity of the external massaging exceeds the Alfven speed within the filament. The net observational magnetic result of the surging, then, depends upon the response of the observing instrument, and whether it essentially observes the mean field, the rms field, or whether there are saturation effects. It is suggested that the chromospheric mottles (spicules) seen in H alpha are in fact the intense magnetic filaments that carry most of the magnetic flux across the photospheric boundary of the sun.

    We consider here small flexural vibrations of an Euler–Bernoulli beam with a lumped mass at one end subject to viscous damping force while the other end is free and the system is set to motion with initial displacement 0() and initial velocity 1(). By investigating the evolution of the motion by Laplace transform, it is proved (in dimensionless units of length and time) that $$\\int_0^1 y_{xt}^2 dx ≤ \\int_0^1 y_{xx}^2 dx, \\quad t>t_0,$$ where 0 may be sufficiently large, provided that {0, 1} satisfy very general restrictions stated in the concluding theorem. This supplies the restrictions for uniform exponential energy decay for stabilization of the beam considered in a recent paper.

    Full Text Available In a recent paper, the authors derived the exact solution for the probability mass function of the geometric distribution of order k, expressing the roots of the associated auxiliary equation in terms of generating functions for Fuss-Catalan numbers. This paper applies the above formalism for the Fuss-Catalan numbers to treat additional problems pertaining to occurrences of success runs. New exact analytical expressions for the probability mass function and probability generating function and so forth are derived. First, we treat sequences of Bernoulli trials with r≥1 occurrences of success runs of length k with l-overlapping. The case l<0, where there must be a gap of at least l trials between success runs, is also studied. Next we treat the distribution of the waiting time for the rth nonoverlapping appearance of a pair of successes separated by at most k-2 failures (k≥2.

  1. Cardinality Balanced Multi-Target Multi-Bernoulli Filter with Error Compensation

    Directory of Open Access Journals (Sweden)

    Xiangyu He

    2016-08-01

    Full Text Available The cardinality balanced multi-target multi-Bernoulli (CBMeMBer filter developed recently has been proved an effective multi-target tracking (MTT algorithm based on the random finite set (RFS theory, and it can jointly estimate the number of targets and their states from a sequence of sensor measurement sets. However, because of the existence of systematic errors in sensor measurements, the CBMeMBer filter can easily produce different levels of performance degradation. In this paper, an extended CBMeMBer filter, in which the joint probability density function of target state and systematic error is recursively estimated, is proposed to address the MTT problem based on the sensor measurements with systematic errors. In addition, an analytic implementation of the extended CBMeMBer filter is also presented for linear Gaussian models. Simulation results confirm that the proposed algorithm can track multiple targets with better performance.

    We consider a model for spacetime in which there is an ubiquitous background Dark Energy which is the Zero Point Field.

Nevertheless we are able to recover meaningful physics, very much in the spirit of Wheeler's Law without Law, that is laws emerging from an underpinning of lawlessness.

    Conceived as a series of more or less autonomous essays, the present book critically exposes the initial developments of continuum thermo-mechanics in a post Newtonian period extending from the creative works of the Bernoullis to the First World war, i.e., roughly during first the “Age of reason” and next the “Birth of the modern world”. The emphasis is rightly placed on the original contributions from the “Continental” scientists (the Bernoulli family, Euler, d’Alembert, Lagrange, Cauchy, Piola, Duhamel, Neumann, Clebsch, Kirchhoff, Helmholtz, Saint-Venant, Boussinesq, the Cosserat brothers, Caratheodory) in competition with their British peers (Green, Kelvin, Stokes, Maxwell, Rayleigh, Love,..). It underlines the main breakthroughs as well as the secondary ones. It highlights the role of scientists who left essential prints in this history of scientific ideas. The book shows how the formidable developments that blossomed in the twentieth century (and perused in a previous book of the author in...

    This monograph is an annotated translation of what is considered to be the world’s first calculus textbook, originally published in French in 1696. That anonymously published textbook on differential calculus was based on lectures given to the Marquis de l’Hôpital in 1691-2 by the great Swiss mathematician, Johann Bernoulli. In the 1920s, a copy of Bernoulli’s lecture notes was discovered in a library in Basel, which presented the opportunity to compare Bernoulli’s notes, in Latin, to l’Hôpital’s text in French. The similarities are remarkable, but there is also much in l’Hôpital’s book that is original and innovative. This book offers the first English translation of Bernoulli's notes, along with the first faithful English translation of l’Hôpital’s text, complete with annotations and commentary. Additionally, a significant portion of the correspondence between l’Hôpital and Bernoulli has been included, also for the fi rst time in English translation. This translation will provide ...

    2008-09-01

    Full Text Available Abstract Background With limited resources available, injury prevention efforts need to be targeted both geographically and to specific populations. As part of a pediatric injury prevention project, data was obtained on all pediatric medical and injury incidents in a fire district to evaluate geographical clustering of pediatric injuries. This will be the first step in attempting to prevent these injuries with specific interventions depending on locations and mechanisms. Results There were a total of 4803 incidents involving patients less than 15 years of age that the fire district responded to during 2001–2005 of which 1997 were categorized as injuries and 2806 as medical calls. The two cohorts (injured versus medical differed in age distribution (7.7 ± 4.4 years versus 5.4 ± 4.8 years, p Conclusion Significant clustering occurs overall for all injury mechanisms combined and for each mechanism depending on the cluster detection method used. There was some overlap in geographic clusters identified by both methods. The Bernoulli method allows more focused cluster mapping and evaluation since it directly uses location data. Once clusters are found, interventions can be targeted to specific geographic locations, location types, ages of victims, and mechanisms of injury.

  9. Using the jackknife for estimation in log link Bernoulli regression models.

    2015-02-10

    Bernoulli (or binomial) regression using a generalized linear model with a log link function, where the exponentiated regression parameters have interpretation as relative risks, is often more appropriate than logistic regression for prospective studies with common outcomes. In particular, many researchers regard relative risks to be more intuitively interpretable than odds ratios. However, for the log link, when the outcome is very prevalent, the likelihood may not have a unique maximum. To circumvent this problem, a 'COPY method' has been proposed, which is equivalent to creating for each subject an additional observation with the same covariates except the response variable has the outcome values interchanged (1's changed to 0's and 0's changed to 1's). The original response is given weight close to 1, while the new observation is given a positive weight close to 0; this approach always leads to convergence of the maximum likelihood algorithm, except for problems with convergence due to multicollinearity among covariates. Even though this method produces a unique maximum, when the outcome is very prevalent, and/or the sample size is relatively small, the COPY method can yield biased estimates. Here, we propose using the jackknife as a bias-reduction approach for the COPY method. The proposed method is motivated by a study of patients undergoing colorectal cancer surgery.

  10. Polytropic index of magnetosheath ions based on homogeneous MHD Bernoulli Integral

    Pang, Xuexia; Cao, Jinbin; Ma, Yuduan

    2016-03-01

    This paper uses Cluster data during the period from 2001 to 2010 to study the polytropic processes of magnetosheath ions. Utilizing the method of homogeneous magnetohydrodynamic (MHD) Bernoulli integral (MBI), we first identify streamflow tubes, then use the constant of polytropic relation to guarantee that the streamflow tube experiences an unchanged polytropic process, and finally determine the polytropic index of ions in these streamflow tubes. The statistical results show that the magnetosheath is a complicated system in which the polytropic index of ions ranges from -2 to 3. The polytropic index distribution of ions is dependent on the electromagnetic energy flux perpendicular to the streamline. The median polytropic index of ions in the magnetosheath is 0.960, 0.965, and 0.974 for perpendicular electromagnetic energy ratio δE × B < 5%, δE × B < 3%, and δE × B < 1%, respectively. There are two basic polytropic processes in the magnetosheath: the dominant isothermal process and the isobaric process. When there is no exchange of electromagnetic energy between neighboring streamflow tubes, the magnetosheath ions are isothermal. However, when the perpendicular electromagnetic energy ratio increases, the isobaric polytropic process starts to emerge. The magnetosheath ion flows are highly localized because most streamflow tubes experiencing same polytropic processes last less than 60 s. Thus, the polytropic index of magnetosheath ion flows is highly variable.

  11. Reverse engineering Boolean networks: from Bernoulli mixture models to rule based systems.

    Directory of Open Access Journals (Sweden)

    Mehreen Saeed

    Full Text Available A Boolean network is a graphical model for representing and analyzing the behavior of gene regulatory networks (GRN. In this context, the accurate and efficient reconstruction of a Boolean network is essential for understanding the gene regulation mechanism and the complex relations that exist therein. In this paper we introduce an elegant and efficient algorithm for the reverse engineering of Boolean networks from a time series of multivariate binary data corresponding to gene expression data. We call our method ReBMM, i.e., reverse engineering based on Bernoulli mixture models. The time complexity of most of the existing reverse engineering techniques is quite high and depends upon the indegree of a node in the network. Due to the high complexity of these methods, they can only be applied to sparsely connected networks of small sizes. ReBMM has a time complexity factor, which is independent of the indegree of a node and is quadratic in the number of nodes in the network, a big improvement over other techniques and yet there is little or no compromise in accuracy. We have tested ReBMM on a number of artificial datasets along with simulated data derived from a plant signaling network. We also used this method to reconstruct a network from real experimental observations of microarray data of the yeast cell cycle. Our method provides a natural framework for generating rules from a probabilistic model. It is simple, intuitive and illustrates excellent empirical results.

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available In the finite element method, there are shortcomings using the conventional formulae to calculate the sectional forces, i.e., the bending moment and the shear force, at any cross-section of Bernoulli-Euler beam under dynamic loads. This paper presents some new finite-element formulae overcoming the shortcomings of the conventional ones to calculate the sectional forces at any cross-section of a Bernoulli-Euler beam on continuously viscoelastic foundation subjected to concentrated moving loads. The proposed formulae can easily degenerate into the formulae for calculating the sectional forces of a simply supported or a continuous Bernoulli-Euler beam subjected to concentrated moving loads, and into the formulae for calculating the sectional forces of a Bernoulli-Euler beam on Winkler foundation under static loads. Five numerical examples including static and dynamic analyses are chosen to illustrate the application of the proposed formulae. Numerical results show: (1 compared with the conventional formulae, the proposed formulae can improve the calculation accuracy of the sectional forces of beam; (2 one should use the proposed formulae, not the conventional formulae, to calculate the sectional forces at any cross-section in Bernoulli-Euler beam.

    According to expressive law theories, expression of values is an important function played by the law. Expressive laws affect behavior, not by threatening sanctions or promising rewards, but by changing individual preferences and tastes and, in some cases, by affecting social norms and values. New laws, however, can run against sticky social norms, failing to achieve their expressive effects. By developing a dynamic model, in this paper we show that inexpressive laws (laws whose expressive fu...

  17. Scrutiny of non-linear differential equations Euler-Bernoulli beam with large rotational deviation by AGM

    2014-12-01

    The kinematic assumptions upon which the Euler-Bernoulli beam theory is founded allow it to be extended to more advanced analysis. Simple superposition allows for three-dimensional transverse loading. Using alternative constitutive equations can allow for viscoelastic or plastic beam deformation. Euler-Bernoulli beam theory can also be extended to the analysis of curved beams, beam buckling, composite beams and geometrically nonlinear beam deflection. In this study, solving the nonlinear differential equation governing the calculation of the large rotation deviation of the beam (or column) has been discussed. Previously to calculate the rotational deviation of the beam, the assumption is made that the angular deviation of the beam is small. By considering the small slope in the linearization of the governing differential equation, the solving is easy. The result of this simplification in some cases will lead to an excessive error. In this paper nonlinear differential equations governing on this system are solved analytically by Akbari-Ganji's method (AGM). Moreover, in AGM by solving a set of algebraic equations, complicated nonlinear equations can easily be solved and without any mathematical operations such as integration solving. The solution of the problem can be obtained very simply and easily. Furthermore, to enhance the accuracy of the results, the Taylor expansion is not needed in most cases via AGM manner. Also, comparisons are made between AGM and numerical method (Runge-Kutta 4th). The results reveal that this method is very effective and simple, and can be applied for other nonlinear problems.

  19. Limit laws for Zipf's law

    International Nuclear Information System (INIS)

    In this communication we establish stochastic limit laws leading from Zipf's law to Pareto's and Heaps' laws. We consider finite ensembles governed by Zipf's law and study their asymptotic statistics as the ensemble size tends to infinity. A Lorenz-curve analysis establishes three types of limit laws for the ensembles' statistical structure: 'communist', 'monarchic', and Paretian. Further considering a dynamic setting in which the ensembles grow stochastically in time, a functional central limit theorem analysis establishes a Gaussian approximation for the ensembles' stochastic growth. The Gaussian approximation provides a generalized and corrected formulation of Heaps' law. (fast track communication)

    A beam-column element based on the Euler-Bernoulli beam theory is researched for nonlinear dynamic analysis of reinforced concrete (RC) structural element. Stiffness matrix of this element is obtained by using rigidity method. A solution technique that included nonlinear dynamic substructure procedure is developed for dynamic analyses of RC frames. A predicted-corrected form of the Bossak-α method is applied for dynamic integration scheme. A comparison of experimental data of a RC column element with numerical results, obtained from proposed solution technique, is studied for verification the numerical solutions. Furthermore, nonlinear cyclic analysis results of a portal reinforced concrete frame are achieved for comparing the proposed solution technique with Fibre element, based on flexibility method. However, seismic damage analyses of an 8-story RC frame structure with soft-story are investigated for cases of lumped/distributed mass and load. Damage region, propagation, and intensities according to both approaches are researched.

  1. A Family of Modified Even Order Bernoulli-Type Multiquadric Quasi-Interpolants with Any Degree Polynomial Reproduction Property

    2014-01-01

    shifts of the function f(x(x∈ℝ to approximate the derivatives of f(x, we propose a family of modified even order Bernoulli-type multiquadric quasi-interpolants which do not require the derivatives of the function approximated at each node and can satisfy any degree polynomial reproduction property. Error estimate indicates that our operators could provide the desired precision by choosing a suitable shape-preserving parameter c and a nonnegative integer m. Numerical comparisons show that this technique provides a higher degree of accuracy. Finally, applying our operators to the fitting of discrete solutions of initial value problems, we find that our method has smaller errors than the Runge-Kutta method of order 4 and Wang et al.’s quasi-interpolation scheme.

  2. Electrohydroelastic Euler-Bernoulli-Morison model for underwater resonant actuation of macro-fiber composite piezoelectric cantilevers

    Bio-inspired hydrodynamic thrust generation using smart materials has received growing attention over the past few years to enable improved maneuverability and agility, small form factor, reduced power consumption, and ease of fabrication in next-generation aquatic swimmers. In order to develop a high-fidelity model to predict the electrohydroelastic dynamics of macro-fiber composite (MFC) piezoelectric structures, in this work, mixing rules-based (i.e. rule of mixtures) electroelastic mechanics formulation is coupled with the global electroelastic dynamics based on the Euler-Bernoulli kinematics and nonlinear fluid loading based on Morison’s semi-empirical model. The focus is placed on the dynamic actuation problem for the first two bending vibration modes under geometrically and materially linear, hydrodynamically nonlinear behavior. The electroelastic and dielectric properties of a representative volume element (piezoelectric fiber and epoxy matrix) between two subsequent interdigitated electrodes are correlated to homogenized parameters of MFC bimorphs and validated for a set of MFCs that have the same overhang length but different widths. Following this process of electroelastic model development and validation, underwater actuation experiments are conducted for different length-to-width aspect ratios (L/b) in quiescent water, and the empirical drag and inertia coefficients are extracted from Morison’s equation to establish the electrohydroelastic model. The repeatability of these empirical coefficients is demonstrated for experiments conducted using aluminum cantilevers of different aspect ratios with a focus on the first two bending modes. The convergence of the nonlinear electrohydroelastic Euler-Bernoulli-Morison model to its hydrodynamically linear counterpart for increased L/b values is also reported. The proposed model, its harmonic balance analysis, and experimental results can be used not only for underwater piezoelectric actuation, but also for

If upon arrival, the server is busy or vacation, the CU8tomer is obliged to leave the service area and to orbit. Each customer in the orbit forms an independent retrial source and the retrial time follows a geometrical law. Just after completion of a customer's service the server may take a vacation of random length or may opt to continue staying in the system to serve the next customer.

  9. Characterization of the Bernoulli-Navier model for a rectangular section beam as the limit of the Kirchhoff-Love model for a plate

    Ribeiro, C.; Viaño, J. M.; Figueiredo, J.; Rodríguez-Arós, Á.

    2016-10-01

    In this paper, we compare the Kirchhoff-Love model for a linearly elastic rectangular plate {Ω^{tɛ}=(0,L)×(-t,t)×(-ɛ,ɛ)} of thickness {2ɛ} with the Bernoulli-Navier model for the same solid considered as a linearly elastic beam of length {L} and cross section {ω_1^{tɛ}=(-t,t)×(-ɛ,ɛ)}. We assume that the solid is clamped on both ends {{0,L}×[-t,t]×[-ɛ,ɛ]}. We show that the scaled version of the displacements field {{{ζ}}^t} in the middle plane, solution of the Kirchhoff-Love model, converges strongly to the unique solution of a one-dimensional problem when the plate width parameter {t} tends to zero. Moreover, after rescaling this limit, we show that, as a matter of fact, it is the solution of the Bernoulli-Navier model for the beam. This means that, under appropriate assumptions on the order of magnitude of the data, the Bernoulli-Navier displacement field is the natural approximation of the Kirchhoff-Love displacement field when the cross section of the plate is rectangular and its width is sufficiently small and homothetic to thickness.

  10. Application of game theory on parameter optimization of the novel two-stage Nash nonlinear grey Bernoulli model

    Science.gov (United States)

    Hsin, Pei-Han; Chen, Chun-I.

    2015-10-01

    In grey prediction modeling, there are three parameters in nonlinear grey Bernoulli model (NGBM), including the power n, the coefficient p and the length of raw data used to construct grey forecasting model. Nash NGBM only optimizes n and p by the iterated elimination of weakly dominated strategies of game theory. To optimize above three parameters, this study develops a two-stage game for NNGBM (abbreviated as two-stage NNGBM). In the first stage, find the Nash equilibrium for each possible game. In the second stage, use Minimax principle to find the optimal left topological sequence which has the best forecasting performance. Then, obtain Nash equilibrium which consists of these three parameters. This study also proves that the traditional GM(1, 1), optimal p GM(1, 1) and NGBM(1, 1) are the special cases of the proposed model. In order to show the feasibility of this research, the proposed method is applied to the forecasting of Taiwan's GDP. The results show that five elements in raw data sequence are optimal topological length for constructing NNGBM in the case of Taiwan's GDP forecasting.

  11. Bernoulli particle filter with observer altitude for maritime radiation source tracking in the presence of measurement uncertainty

    Institute of Scientific and Technical Information of China (English)

    Luo Xiaobo; Fan Hongqi; Song Zhiyong; Fu Qiang

    2013-01-01

    For maritime radiation source target tracking in particular electronic counter measures (ECM) environment, there exists two main problems which can deteriorate the tracking perfor-mance of traditional approaches. The first problem is the poor observability of the radiation source. The second one is the measurement uncertainty which includes the uncertainty of the target appear-ing/disappearing and the detection uncertainty (false and missed detections). A novel approach is proposed in this paper for tracking maritime radiation source in the presence of measurement uncertainty. To solve the poor observability of maritime radiation source target, using the radiation source motion restriction, the observer altitude information is incorporated into the bearings-only tracking (BOT) method to obtain the unique target localization. Then the two uncertainties in the ECM environment are modeled by the random finite set (RFS) theory and the Bernoulli filtering method with the observer altitude is adopted to solve the tracking problem of maritime radiation source in such context. Simulation experiments verify the validity of the proposed approach for tracking maritime radiation source, and also demonstrate the superiority of the method compared with the traditional integrated probabilistic data association (IPDA) method. The tracking perfor-mance under different conditions, particularly those involving different duration of radiation source opening and switching-off, indicates that the method to solve our problem is robust and effective.

  12. Free vibration analysis of DWCNTs using CDM and Rayleigh-Schmidt based on Nonlocal Euler-Bernoulli beam theory.

    De Rosa, Maria Anna; Lippiello, Maria

    2014-01-01

    The free vibration response of double-walled carbon nanotubes (DWCNTs) is investigated. The DWCNTs are modelled as two beams, interacting between them through the van der Waals forces, and the nonlocal Euler-Bernoulli beam theory is used. The governing equations of motion are derived using a variational approach and the free frequencies of vibrations are obtained employing two different approaches. In the first method, the two double-walled carbon nanotubes are discretized by means of the so-called "cell discretization method" (CDM) in which each nanotube is reduced to a set of rigid bars linked together by elastic cells. The resulting discrete system takes into account nonlocal effects, constraint elasticities, and the van der Waals forces. The second proposed approach, belonging to the semianalytical methods, is an optimized version of the classical Rayleigh quotient, as proposed originally by Schmidt. The resulting conditions are solved numerically. Numerical examples end the paper, in which the two approaches give lower-upper bounds to the true values, and some comparisons with existing results are offered. Comparisons of the present numerical results with those from the open literature show an excellent agreement.

  13. Dynamical equations for the vector potential and the velocity potential in incompressible irrotational Euler flows: a refined Bernoulli theorem.

    Ohkitani, Koji

    2015-09-01

    We consider incompressible Euler flows in terms of the stream function in two dimensions and the vector potential in three dimensions. We pay special attention to the case with singular distributions of the vorticity, e.g., point vortices in two dimensions. An explicit equation governing the velocity potentials is derived in two steps. (i) Starting from the equation for the stream function [Ohkitani, Nonlinearity 21, T255 (2009)NONLE50951-771510.1088/0951-7715/21/12/T02], which is valid for smooth flows as well, we derive an equation for the complex velocity potential. (ii) Taking a real part of this equation, we find a dynamical equation for the velocity potential, which may be regarded as a refinement of Bernoulli theorem. In three-dimensional incompressible flows, we first derive dynamical equations for the vector potentials which are valid for smooth fields and then recast them in hypercomplex form. The equation for the velocity potential is identified as its real part and is valid, for example, flows with vortex layers. As an application, the Kelvin-Helmholtz problem has been worked out on the basis the current formalism. A connection to the Navier-Stokes regularity problem is addressed as a physical application of the equations for the vector potentials for smooth fields.

  14. The exact explicit dynamic stiffness matrix of multi-cracked Euler-Bernoulli beam and applications to damaged frame structures

    Science.gov (United States)

    Caddemi, S.; Caliò, I.

    2013-06-01

    In this paper the closed form expression of the exact dynamic stiffness matrix of an Euler-Bernoulli beam in the presence of an arbitrary number of concentrated cracks is derived. The procedure adopted for the evaluation of the dynamic stiffness matrix is based on the availability of the exact closed form solution of the vibration modes of the multi-cracked beam, derived by the same authors in a previous paper. The knowledge of the exact explicit dynamic stiffness matrix of the multi-cracked beam makes the direct evaluation of the exact global dynamic stiffness matrix of damaged frame structures possible. Furthermore, it allows the exact evaluation of the frequencies and the corresponding vibration modes, consistent with the distributed parameter model, through the application of the well-known Wittrick-Williams algorithm. Some numerical applications, relative to the evaluation of frequencies and the corresponding mode shapes of multi-cracked framed structure, are reported. Furthermore, the closed-form solution has been validated by comparing with some exact results available in the literature, for a simple single cracked frame. Finally, further new results for a multi-cracked frame have been compared with those obtained by a finite element simulation.

    Considering the uncertainty of measurement origin deriving from the random surviving multi-target, clutter, and the missed detection of sensor, a multi-range hypothesis Bernoulli filter is proposed in order to solve the bearings-only tracking problem. Firstly, a multi-range hypothesis based bearings-only measurement equation is modeled in Cartesian coordinates. Then, a Gaussian mixture multi-range hypothesis cardinality-balanced multi-target multi-Bernoulli filter is derived and proposed. Finally, an adaptive bearings-only birth multi-Bernoulli density is proposed.

    In this article, we study the locally distributed feedback stabilization problem of a nonuniform Euler-Bernoulli beam. Firstly, using the semi-group theory, we establish the wellposedness of the associated closed loop system. Then by proving the uniqueness of the solution to a related ordinary differential equation, we derive the asymptotic stability of the closed loop system. Finally, by means of the piecewise multiplier method, we prove that, by either one distributed force feedback or a distributed moment feedback control, the closed loop system can be exponentially stabilized.

    Full Text Available The law system of a State represents the body of rules passed or recognized by that State inorder to regulate the social relationships, rules that must be freely obeyed by their recipients, otherwisethe State intervening with its coercive power. Throughout the development of the society, pedants havebeen particularly interested in the issue of law systems, each supporting various classifications; theclassification that has remained is the one distinguishing between the Anglo-Saxon, the Roman-German,the religious and respectively the communist law systems. The third main international law system is theMuslim one, founded on the Muslim religion – the Islam. The Islam promotes the idea that Allah createdthe law and therefore it must be preserved and observed as such. Etymologically, the Arabian word“Islam” means “to be wanted, to obey” implying the fact that this law system promotes total andunconditioned submission to Allah. The Islamic law is not built on somebody of laws or leading cases,but has as source. The Islam is meant as a universal religion, the Koran promoting the idea of the unityof mankind; thus, one of the precepts in the Koran asserts that “all men are equal (…, there is nodifference between a white man and a black man, between one who is Arabian and one who is not,except for the measure in which they fear God.” The Koran is founded mainly on the Talmud, Hebrewsource of inspiration, and only on very few Christian sources. The Islam does not forward ideas whichcannot be materialized; on the contrary its ideas are purely practical, easy to be observed by the commonman, ideas subordinated to the principle of monotheism. The uncertainties and gaps of the Koran, whichhave been felt along the years, imposed the need for another set of rules, meant to supplement it – that isSunna. Sunna represents a body of laws and, consequently, the second source of the Koran. Sunnanarrates the life of the prophet Mohamed, the model to

    The concept of mechanical work is inherited from the concepts of potentia absoluta and men's work, both implemented in the Section IX of Daniel Bernoulli's Hydrodynamica in 1738. Nonetheless, Bernoulli did not confuse those two entities: he defined a link from gender to species between the former, general, and the latter, organic. Besides, Bernoulli clearly distinguished vis viva and potentia absoluta (or work). Their mutual conversions are rarely explicitly mentionned in this book, except once, in the Section X of his work, from vis viva to work, and subordinated to the mediation of a machine, in a driving forces substitution problem. His attitude significantly evolved in a text in 1753, in which work and vis viva were unambiguously connected, while the concept of potentia absoluta was reduced to the one of men's work, and the expression itself was abandoned. It was then accepted that work can be converted into vis viva, but the opposite is true in only one case, the intra-organic one. The concept of tiredne...

  16. Case law

    International Nuclear Information System (INIS)

    The first point concerns the judgement of the federal Administration Court on the standing of third parties regarding attacks at interim storage facilities (2008). In its judgement handed down on 10. april 2008, the german Federal Administrative Court overrules a decision of a Higher Regional Administrative Court and declares that residents in the vicinity of an interim storage facility may challenge the licence for that facility on the grounds that the necessary protection has not been provided against disruptive action or other interference by third parties. The second point concerns the judgement of the European Court of justice of a member State to fulfill obligations under directive 96/29 EURATOM (2007): the united kingdom imposed to intervene only if a situation of radioactive contamination results from a present or past activity for the exercise of which a licence was granted. The national legislation does not oblige the authorities to take measures in circumstances in which radioactive contamination results from a past practice which was not the subject of a such licence. The United Kingdom Government admitted the validity of the Commission claims adding that further legislation to transpose that article (article 53) into national laws is in the process of being drawn up. The third point is relative to judgement of the US court of Appeals on licensing of the L.E.S. uranium enrichment facility (2007), on appeal to the Federal Court of Appeals for the district of Columbia, the joint petitioners objected to the Nuclear regulatory Commission (NRC) issuing to the Louisiana Energy Services, L.P.

  4. Application of simplest equations of Bernoulli and Riccati kind for obtaining exact traveling-wave solutions for a class of PDEs with polynomial nonlinearity

    Science.gov (United States)

    Vitanov, Nikolay K.

    2010-08-01

    We search for traveling-wave solutions of the class of equations ∑p=1N1αp{∂pQ}/{∂tp}+∑q=1N2βq{∂qQ}/{∂xq}+∑m=1MμmQm=0 where αp,βq and μm are parameters. We obtain such solutions by the method of simplest equation for the cases when the simplest equation is the the equation of Bernoulli or the equation of Riccati. We modify the methodology of the simplest equation of Kudryashov as follows. Kudryashov uses the first step of the test for Painleve property in order to determine the size of the solution of the studied PDE. We divide the studied PDEs in two parts: part A which contains the derivatives, and part B which contains the rest of the equation. The application of the ansatz or the extended ansatz of Kudryashov, transforms part A and part B to two polynomials. We balance the highest powers of the polynomials for the parts A and B and, thus obtain a balance equation which depends on the kind of the used simplest equation. The balance equations are connected to nonlinear algebraic systems of relationships among the parameters of the equations and the parameters of the solution. On the basis of these systems, we obtain numerous solutions of the studied class of equations.

    2013-01-01

    The current endeavor intended to evaluate the effectiveness and mode of action of Anuloma-Viloma Pranayama (AVP), i.e., alternate nasal breathing exercise, in resolving clinical features of Pratishyaya, i.e., rhinosinusitis. The present study was directed to validate the use of classical “saccharin test” in measuring the nasal health by measuring mucociliary clearance time. This study also highlights the effects of AVP by application of Bernoulli principle in ventilation of paranasal sinuses and surface oxygenation of nasal and paranasal sinuses ciliary epithelium. Clinically, endoscopically and radiologically diagnosed patients of Pratishyaya, i.e., rhinosinusitis, satisfying the inclusion criteria were selected to perform AVP as a breathing exercise regularly for 30 min every day in order to evaluate the effectiveness of AVP in resolving features of rhinosinusitis. Saccharin test was performed before and after completion of 40 days trial to assess the nasal ciliary activity, which has been proved to be directly related to the health of ciliary epithelium and nasal health overall as well. AVP may be regarded as a catalyst to conspicuously enhance ventilation and oxygenation of the paranasal sinuses and the positively effect the nasal respiratory epithelium by increasing better surface availability of oxygen and negative pressure in the nasal cavity itself.

    2013-04-01

    National Federation of Independent Business v. Sebelius, the Supreme Court's ruling on the Patient Protection and Affordable Care Act, is a landmark decision - both for constitutional law and for health care law and policy. Others will study its implications for constitutional limits on a range of federal powers beyond health care. This article considers to what extent the decision is also about health care law, properly conceived. Under one view, health care law is the subdiscipline that inquires how courts and government actors take account of the special features of medicine that make legal or policy issues especially problematic - rather than regarding health care delivery and finance more generically, like most any other economic or social enterprise. Viewed this way, the opinions from the Court's conservative justices are mainly about general constitutional law principles. In contrast, Justice Ruth Bader Ginsburg's dissenting opinion for the four more liberal justices is just as much about health care law as it is about constitutional law. Her opinion gives detailed attention to the unique features of health care finance and delivery in order to inform her analysis of constitutional precedents and principles. Thus, the Court's multiple opinions give a vivid depiction of the compelling contrasts between communal versus individualistic conceptions of caring for those in need, and between health care and health insurance as ordinary commodities versus ones that merit special economic, social, and legal status.

    SummaryIn a world with water resources severely impacted by technology, science must actively contribute to water law. To this end, this paper is an earth scientist's attempt to comprehend essential elements of water law, and to examine their connections to science. Science and law share a common logical framework of starting with a priori prescribed tenets, and drawing consistent inferences. In science, observationally established physical laws constitute the tenets, while in law, they stem from social values. The foundations of modern water law in Europe and the New World were formulated nearly two thousand years ago by Roman jurists who were inspired by Greek philosophy of reason. Recognizing that vital natural elements such as water, air, and the sea were governed by immutable natural laws, they reasoned that these elements belonged to all humans, and therefore cannot be owned as private property. Legally, such public property was to be governed by jus gentium, the law of all people or the law of all nations. In contrast, jus civile or civil law governed private property. Remarkably, jus gentium continues to be relevant in our contemporary society in which science plays a pivotal role in exploiting vital resources common to all. This paper examines the historical roots of modern water law, follows their evolution through the centuries, and examines how the spirit of science inherent in jus gentium is profoundly influencing evolving water and environmental laws in Europe, the United States and elsewhere. In a technological world, scientific knowledge has to lie at the core of water law. Yet, science cannot formulate law. It is hoped that a philosophical understanding of the relationships between science and law will contribute to their constructively coming together in the service of society.

This is also necessary for reasons of social policy, since such a juridicial decision produces an effect which spreads far beyond the litigants. In a constitutional state that has to stand the test in the conflict arising between human rights and technical progress, the controversy on basic rights has to form a part of the trial and of the opinion. There are two sides to the rule of law: The citizen's obligation not to use violence, and his right to be strictly protected by the Basic Law. (HSCH)

  6. Statistical laws in linguistics

    CERN Document Server

    Altmann, Eduardo G

    2015-01-01

    Zipf's law is just one out of many universal laws proposed to describe statistical regularities in language. Here we review and critically discuss how these laws can be statistically interpreted, fitted, and tested (falsified). The modern availability of large databases of written text allows for tests with an unprecedent statistical accuracy and also a characterization of the fluctuations around the typical behavior. We find that fluctuations are usually much larger than expected based on simplifying statistical assumptions (e.g., independence and lack of correlations between observations).These simplifications appear also in usual statistical tests so that the large fluctuations can be erroneously interpreted as a falsification of the law. Instead, here we argue that linguistic laws are only meaningful (falsifiable) if accompanied by a model for which the fluctuations can be computed (e.g., a generative model of the text). The large fluctuations we report show that the constraints imposed by linguistic laws...

    Full Text Available The state as an international entity and its impact on the individual’s right has been and still continues to be a crucial factor in the relationship between private and public persons. States vary in terms of their political system, however, democratic states are based on the separation of powers and human rights within the state. Rule of law is the product of many actors in a state, including laws, individuals, society, political system, separation of powers, human rights, the establishment of civil society, the relationship between law and the individual, as well as, individual-state relations. Purpose and focus of this study is the importance of a functioning state based on law, characteristics of the rule of law, separation of powers and the basic concepts of the rule of law.

    1996-11-01

    Hack's law is reviewed, emphasizing its implications for the elongation of river basins as well as its connections with their fractal characteristics. The relation between Hack's law and the internal structure of river basins is investigated experimentally through digital elevation models. It is found that Hack's exponent, elongation, and some relevant fractal characters are closely related. The self-affine character of basin boundaries is shown to be connected to the power law decay of the probability of total contributing areas at any link and to Hack's law. An explanation for Hack's law is derived from scaling arguments. From the results we suggest that a statistical framework referring to the scaling invariance of the entire basin structure should be used in the interpretation of Hack's law.

A recent model of random group formation [RGF] attempts a general explanation of such phenomena based on Jaynes' notion of maximum entropy applied to a particular choice of cost function. In the present article I argue that the cost function used in the RGF model is in fact unnecessarily complicated, and that power laws can be obtained in a much simpler way by applying maximum entropy ideas directly to the Shannon entropy subject only to a single constraint: that the average of the logarithm of the observable quantity is specified.

    Zipf's law, and power laws in general, have attracted and continue to attract considerable attention in a wide variety of disciplines—from astronomy to demographics to software structure to economics to linguistics to zoology, and even warfare. A recent model of random group formation (RGF) attempts a general explanation of such phenomena based on Jaynes' notion of maximum entropy applied to a particular choice of cost function. In the present paper I argue that the specific cost function used in the RGF model is in fact unnecessarily complicated, and that power laws can be obtained in a much simpler way by applying maximum entropy ideas directly to the Shannon entropy subject only to a single constraint: that the average of the logarithm of the observable quantity is specified.

    of the concept of enjoyment is instructive, and looking at it more closely makes it possible to spell out why obedience in itself does not suffice for a moral existence. Subjecting ourselves to the prescriptions of positive law might actually function as a way of escaping the insatiable demands of the moral law....... In this case, the positive law not only sustains our enjoyment (by securing basic liberties), but also comes to function as an object of enjoyment itself....

    We often think of law as fulfilling certain social functions; for instance, it is said to guide behaviour, maintain order, settle disputes, and provide benefits and services. In the social sciences, more general claims are also made that law stabilizes the dominant mode of production, promotes economic efficiency, secures patriarchy, and so on. 1 What do these claims mean, and what do they contribute to our understanding of law as a social institution? Those are the questions I want to explor...

  16. CONSTANT ASPECTS OF LAW

    Full Text Available "Are we watching, in the succession of history, the appearance and disappearance of legal systems or assisting, in a greater or lesser extent, to what might be considered, in a sense, an evolution of those systems?"1 Law, indissolubly linked to the general evolution of society, has recorded a number of differences in time and space, both in terms of content of various types and positive law systems, and also in terms of forms that take the rules of law, authorities who have the ability to edict it or the procedure to be followed.Indeed, there is no law for all times and all places, as law is not an abstract product of our reason, it comes from the human experience, it is a product of history and that is why institutions of each society can only be different from one society to another.2 But, as in reality there are not quantities of history - many, little or very little - but just history3, we can say that in typology there is not socialist law absolutely different from bourgeois, feudal or slave law, so there is just law. By this approach, I wanted to bring back into question the existence of some factors of constancy in law, those "legal permanencies” investigated by Edmond Picard, believing that "there is something in the legal relationship that necessarily subsist anywhere”.4

  18. Thinking law: thinking law in motion

    Directory of Open Access Journals (Sweden)

    Laura Beth Nielsen

    2014-07-01

    Full Text Available This essay argues that one way to “think law” is to think “law in motion”. I will argue that a “law in motion” perspective embodies four core elements or ‘multiplicities’ which are: (1 multiple methodologies; (2 multiple perspectives; (3 multiple vocalities; and (4 multiple media including objects. As will become evident by the number of inspiring colleagues that have articulated rationales and perspectives for each of these multiplicities, these are not original ideas for which I can claim credit. And yet, the attempt to put them together in a comprehensive schema with consideration for all four of the multiplicities in the same project, demonstrates that a law in motion perspective can bear new fruit. To do this, my article combines analysis of some of the research in Law & Society that exemplifies these trends and my own research on employment civil rights litigation to interrogate the necessity of a “multiple” approach for our “multiple futures.”

    Mayoral Diaz-Asensio, Juan Antonio; Jaremba, Urszula; Nowak, Tobias

    2014-01-01

    The judicial protection system in the European Union (EU) is premised on the fact that national judges are supposed to act as decentralized EU judges. This role is exercised through tools enshrined in, inter alia, primacy, direct and indirect effect of EU law, and the preliminary ruling procedure....... However, a number of studies show that national judges experience difficulties in exercising EU competences due to their lack of knowledge in the field of EU law. In this contribution we study the differences in the level of self-evaluation of EU law knowledge among judges, which consequently influence...... the way judges approach EU law. For that purpose we question the relevance of several institutional and socio-legal factors, such as organization of the judiciary, generation, the system of legal education and judicial training and practical experience with EU law. Our analysis is based on data collected...

    CERN Document Server

    Mittelstaedt, Peter

    2005-01-01

    The book is concerned with the laws of nature and in particular with the laws of physics. The authors discuss three important questions: First, whether the observed regularities are based on strict "laws of nature" that hold rigorously and without any exception. Second, what we call a "law of nature" is studied by comparing this concept with invariance principles, causality principles, teleological principles and means of predicting future events. Finally, on the basis of these investigations the authors treat the ambitious and intricate third question, why the laws of nature hold. Are there rational reasons for this largely unexplained phenomenon? This book addresses students as well as researchers. It will be an excellent reference for those interested in the philosophical foundations of the natural sciences.

    2015-03-01

    We analyze the temperature relaxation phenomena of systems in contact with a thermal reservoir that undergoes a non-Markovian diffusion process. From a generalized Langevin equation, we show that the temperature is governed by a law of cooling of the Newton's law type in which the relaxation time depends on the velocity autocorrelation and is then characterized by the memory function. The analysis of the temperature decay reveals the existence of an anomalous cooling in which the temperature may oscillate. Despite this anomalous behavior, we show that the variation of entropy remains always positive in accordance with the second law of thermodynamics.

    Full Text Available Constitutionalizaton of Law’s different areas is a phenomenon gradually more ingrained in our cultural and legal framework. Maybe the best demonstration is the increasingly prominent role of the Constitutional Court (TC – Constitution’s Supreme Interpreter – in defining and redefining concepts, rights and legal principles touching a range of subjects, from TaxLaw to Human Rights. This is relevant to understand the Law and its current effects whether it is valued positively or negatively.

  20. GENERAL PRINCIPLES OF LAW

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available According to Professor Djuvara “law can be a science, and legal knowledge can also become science when, referring to a number as large as possible of acts of those covered by law, sorts and connects them by their essential characters upon legal concepts or principles which are universally valid, just like the laws of nature”. The general principles of law take a privileged place in the positive legal order and represent the foundation of any legal construction. The essence of the legal principles resides in their generality. In respect of the term “general”, Franck Moderne raised the question on the degree of generality used in order to define a principle as being general – at the level of an institution, of a branch of the law or at the level of the entire legal order. The purpose of this study is to find out the characteristics of law principles. In our opinion, four characteristics can be mentioned.

  5. A new German law

    International Nuclear Information System (INIS)

    A new law about the production of electricity came into effect last april in Germany. A renewable energy expert presents this law and its consequences to the electricity market. The previous EFL (electricity feed-in law, 1991) has greatly contributed to the development of wind energy during the last decade but a new law was necessary to comply with European regulations about free electricity market and with European Commission 's aim of doubling the contribution of renewable energies to the European energy balance by 2010. This law sets the purchase prices of electricity by delivery companies according to the renewable energy (wind, photovoltaic,biomass, biogas, mine gas and geothermal) and a compensation system has been thoroughly elaborated. At the end the customer will have to pay the bill but the price is reasonable, the extra-cost is expected to be somewhere between 35 and 70 French francs a year for each electricity consumer but with the perspective of a doubling of the contribution of renewable energies to the German electricity market between 1995 and 2010.

  8. Fractal probability laws.

    2008-06-01

    We explore six classes of fractal probability laws defined on the positive half-line: Weibull, Frechét, Lévy, hyper Pareto, hyper beta, and hyper shot noise. Each of these classes admits a unique statistical power-law structure, and is uniquely associated with a certain operation of renormalization. All six classes turn out to be one-dimensional projections of underlying Poisson processes which, in turn, are the unique fixed points of Poissonian renormalizations. The first three classes correspond to linear Poissonian renormalizations and are intimately related to extreme value theory (Weibull, Frechét) and to the central limit theorem (Lévy). The other three classes correspond to nonlinear Poissonian renormalizations. Pareto's law--commonly perceived as the "universal fractal probability distribution"--is merely a special case of the hyper Pareto class.

  9. Online Law Dictionaries

    Online dictionaries that assist users in writing legal texts in English as a foreign language are important lexicographic tools. They can help law students bridge the factual and linguistic gaps between the two legal universes involved. However, existing online law dictionaries with English...... in English as a foreign language. The function theory of lexicography offers an appropriate basis as it focuses on three key concepts: user needs, user competences, and user situations. It is proposed that online dictionaries should be designed to satisfy the lexicographically relevant user needs...... by containing the types of data that can best satisfy the needs of students at the three stages of legal text production: draft writing, revising and editing. The theoretical aspects discussed are supported by examples from the online CISG Dictionary, which is a lexicographic tool developed to help Danish law...

  10. Technical rules in law

    International Nuclear Information System (INIS)

    An important source of knowledge for technical experts is the state of the art reflected by catalogues of technical rules. Technical rules may also achieve importance in law due to a legal transformation standard. Here, rigid and flexible reference are controversial with regard to their admissibility from the point of view of constitutional law. In case of a divergence from the generally accepted technical rules, it is assumed - refutably - that the necessary care had not been taken. Technical rules are one out of several sources of information; they have no normative effect. This may result in a duty of anyone applying them to review the state of technology himself. (orig.)

    The purpose of this article is to identify a limit to the appropriate application of property law to the use and storage of bodily material. I argue here that property law ought to be limited to protecting 'contingent rights' and that recent cases where property rights have been recognised in semen represent the application of property law beyond this limit. I also suggest how the law ought to develop in order to avoid the overextensive use of property law.

  14. Law and individuality

    Directory of Open Access Journals (Sweden)

    D.F.M. Strauss

    2007-07-01

    Full Text Available The main contours of the history of philosophical and scientific conceptions of law and individuality are portrayed. This includes an account of perspectives and views found in ancient Greece, the Graeco-Roman world, the medieval speculation and, via the Renaissance, in early modern developments that were continued in the Enlightenment era, in Romanticism and historicism, and were eventually manifested in the linguistic turn. What is important for a proper understanding of modern law conceptions is an acknowledgement of the all-pervading influence of modern nominalism. This orientation was characterised by employing two related distinctions, namely the distinction between conceptual knowledge and concept-transcending knowledge, and that between rationalism and irrationalism. From a systematic point of view, various aspectual terms provide a frame of reference for the idea of a law of nature as a compound basic concept of science. Special attention is given to the nature of normative principles and physical laws. In the last part of the article, these perspectives are applied to a brief assessment of differences and similarities in the thought of Dooyeweerd and Vollenhoven.

  20. Around the circular law

    CERN Document Server

    Bordenave, Charles

    2011-01-01

    These expository notes are centered around the circular law theorem, which states that the empirical spectral distribution of a n \\times n random matrix with i.i.d. entries of variance 1/n tends to the uniform law on the unit disc of the complex plane as the dimension n tends to infinity. This phenomenon is the non-Hermitian counterpart of the semi circular limit for Wigner random Hermitian matrices, and the quarter circular limit for Marchenko-Pastur random covariance matrices. We present a proof in a Gaussian case, due to Silverstein, based on a formula by Ginibre, and a proof of the universal case by revisiting the approach of Tao and Vu, based on the Hermitization of Girko, the logarithmic potential, and the control of the small singular values. Beyond the finite variance model, we also consider the case where the entries have heavy tails, by using the objective method of Aldous and Steele borrowed from randomized combinatorial optimization. The limiting law is then no longer the circular law and is relat...

  6. Energy and Environmental Law

    International Nuclear Information System (INIS)

    The importance of a comprehensive, efficient and safe electric power supply is beyond question. The energy issue represents, particularly in Europe which is poor in natural resources, one of the central challenges of this young century. It undoubtedly has to be solved, but not independent of other geopolitical challenges like especially environmental problems. In view of ongoing climate change, melting ice caps and expansion of desert areas , an energy policy can not be operated (any more) without regard to environmental law aspects. Based on the available network of the different jurisdictions and the increasing number of environmentally relevant energy standards an integrative approach is obvious. Even in the development of the electricity industry it can be seen that the trend in Europe is characterized by a growing environmental awareness. Accompanying this, the liberalization of energy markets and the growing demand in the energy sector led to a realignment of the global energy market. At union legal level the development of an independent environmental law took place in the recent years. Be it the Alpine Convention, Natura 2000 or the Water Framework Directive: all are detached from a purely economic point of view and concerned with the protection of the environment. The claim for the future is a sustainable energy supply. This paper attempts to present a comprehensive system of energy environmental law. The guiding question was therefore the question of whether or to what extent there is a coherent system of energy environmental law. (Kancsar)

  11. Archie's law - a reappraisal

    Science.gov (United States)

    Glover, Paul W. J.

    2016-07-01

    When scientists apply Archie's first law they often include an extra parameter a, which was introduced about 10 years after the equation's first publication by Winsauer et al. (1952), and which is sometimes called the "tortuosity" or "lithology" parameter. This parameter is not, however, theoretically justified. Paradoxically, the Winsauer et al. (1952) form of Archie's law often performs better than the original, more theoretically correct version. The difference in the cementation exponent calculated from these two forms of Archie's law is important, and can lead to a misestimation of reserves by at least 20 % for typical reservoir parameter values. We have examined the apparent paradox, and conclude that while the theoretical form of the law is correct, the data that we have been analysing with Archie's law have been in error. There are at least three types of systematic error that are present in most measurements: (i) a porosity error, (ii) a pore fluid salinity error, and (iii) a temperature error. Each of these systematic errors is sufficient to ensure that a non-unity value of the parameter a is required in order to fit the electrical data well. Fortunately, the inclusion of this parameter in the fit has compensated for the presence of the systematic errors in the electrical and porosity data, leading to a value of cementation exponent that is correct. The exceptions are those cementation exponents that have been calculated for individual core plugs. We make a number of recommendations for reducing the systematic errors that contribute to the problem and suggest that the value of the parameter a may now be used as an indication of data quality.

  13. Hubble's Law Implies Benford's Law for Distances to Galaxies

    Science.gov (United States)

    Hill, Theodore P.; Fox, Ronald F.

    2016-03-01

    A recent article by Alexopoulos and Leontsinis presented empirical evidence that the first digits of the distances from the Earth to galaxies are a reasonably good fit to the probabilities predicted by Benford's law, the well known logarithmic statistical distribution of significant digits. The purpose of the present article is to give a theoretical explanation, based on Hubble's law and mathematical properties of Benford's law, why galaxy distances might be expected to follow Benford's law. The new galaxy-distance law derived here, which is robust with respect to change of scale and base, to additive and multiplicative computational or observational errors, and to variability of the Hubble constant in both time and space, predicts that conformity to Benford's law will improve as more data on distances to galaxies becomes available. Conversely, with the logical derivation of this law presented here, the recent empirical observations may be viewed as independent evidence of the validity of Hubble's law.

    2016-01-01

    Although the last forty years has seen considerable growth in the use of statistics in legal proceedings, it is primarily classical statistical methods rather than Bayesian methods that have been used. Yet the Bayesian approach avoids many of the problems of classical statistics and is also well suited to a broader range of problems. This paper reviews the potential and actual use of Bayes in the law and explains the main reasons for its lack of impact on legal practice. These include misconceptions by the legal community about Bayes’ theorem, over-reliance on the use of the likelihood ratio and the lack of adoption of modern computational methods. We argue that Bayesian Networks (BNs), which automatically produce the necessary Bayesian calculations, provide an opportunity to address most concerns about using Bayes in the law. PMID:27398389

  6. Sovereignty in International Law

    2015-03-01

    Full Text Available We aimed at highlighting in this paper, after analyzing the transformations that took place in the international society, the importance of a particularly sensitive and current topic for public international law, namely the sovereignty. A political and legal concept at the same time, the state sovereignty remains permanently into the attention of researchers in an attempt to determine its role in international relations governed by the international law. The concept of sovereignty is complex, it can be analyzed in terms of the national law, but as a member of international society, a State participates in international relations on the basis of sovereign equality principle, which causes another meaning of sovereignty, which completes the one specific to the internal life. We have analyzed the evolution of the concept of sovereignty and we have identified the causes that led to changes in its characteristics, in order to predict the tendencies in its development. We have highlighted the aspects of the exercise of sovereignty as a result of limiting the powers of state in the favor of international bodies. In preparing this article we have used as research methods the analysis of the problems generated by mentioned subject with reference to the doctrinal views expressed in specialized papers, documentary research, and interpretation of legal norms in the field.

    Federal, state, and local laws in the US now govern almost every aspect of sexuality. This includes sexuality at the workplace, sexuality education, adolescent sexuality, access to sexuality information and sexually explicit materials, sexual orientation, and sexually transmitted disease(STD)/HIV transmission. Almost 33% of the US Supreme Court's docket this past term concerned sexuality issues. In contrast to 50 years ago, when sexuality law was confined to the criminal arena, contemporary "sex crimes" primarily relate to nonconsensual and exploitative behaviors. It is time for lawmakers, judges, lawyers, policy analysts, lobbyists, and advocates to realize they cannot legislate or litigate how, when, or why people fall in love. Rather, the role of the law should be to create and preserve models of justice and equality that seek to preserve one's individual rights to privacy and freedom to choose in matters related to one's sexuality. This includes free access to age-appropriate sexuality information, the right to marriage and children regardless of sexual orientation, comprehensive sexuality education that encompasses information about avoiding unwanted pregnancies and HIV/STDs, access to contraception and abortion, protection from sexually abusive or exploitative relationships, and access to sexual health care.

  12. Hubble's Law Implies Benford's Law for Distances to Stars

    CERN Document Server

    Fox, Ronald F

    2014-01-01

    A recent article by Alexopoulos and Leontsinis presented empirical evidence that the distances to stars listed in the 2011 HYG database "follow well the probabilities predicted by Benford's law", the well known logarithmic statistical distribution of significant digits. The purpose of the present article is to give a theoretical explanation, based on Hubble's law and mathematical properties of Benford's law, why star distances might be expected to follow Benford's law. Conversely, with the logical derivation given here, the empirical observations may be viewed as new independent evidence of the validity of Hubble's law.

    This paper presents two interesting scaling laws, which relate some critical exponents in the critical behavior of spherically symmetric gravitational collapses. These scaling laws are independent of the details of gravity theory under consideration and share similar forms as those in thermodynamic and geometrical phase transitions in condensed matter system. The properties of the scaling laws are discussed and some numerical checks are given.

    Dias Varella, Marcelo

    2014-01-01

    The book provides an overview of how international law is today constructed through diverse macro and microprocesses that expand its traditional subjects and sources, with the attribution of sovereign capacity and power to the international plane (moving the international toward the national). Simultaneously, national laws approximate laws of other nations (moving among nations or moving the national toward the international) and new sources of legal norms emerge, independent of states and international organisations. This expansion occurs in many subject areas, with specific structures: commercial, environmental, human rights, humanitarian, financial, criminal and labor law contribute to the formation of post national law with different modes of functioning, different actors and different sources of law that should be understood as a new complexity of law.

    I noticed during the last years of my research that when it comes to data law, people are only interested into data protection, human rights etc.As a result, data law is often reduced as data protection law or, even worse, as “privacy law”. Such a point of view is not wrong because data law do protect – or at least genuinely tries to protect – privacy, human rights etc. But by doing so, one is likely to refer only to a small part of data law and, what is worse, not to the essential part of it...

When analyzing the insolvency laws of various jurisdictions such foundation will also show up in the variety of insolvency laws. But certain aspect of insolvency law will be affected by local legal culture, basic rights and the way in which a system deals with related matters such as the security rights provided for, or the approach to labor issues for instance.

    Full Text Available Security law, or more comprehensively conflict and security law, on the international level represents the intersection of three distinct but interrelated fields: international humanitarian law (the law of armed conflict, jus in bello, the law of collective security (most identified with the United Nations (UN system, jus ad bellum and arms control law (including non-proliferation. Security in this sense is multifaceted - interest security, military security and, as is often referred to in the context of the EU, human security. As such, the law covers a wide range of specific topics with respect to conflict, encompassing the use of force, including choice of weapons and fighting techniques, extending to the rules applicable in peacekeeping and peace enforcement, and yet also dictating obligations outside the context of conflict, such as safeguarding and securing dual-use materials (those with both peaceful and military applications to prevent malicious use.

    Full Text Available This article is a substantive analysis tracing the legal, philosophical, social, historical, jurisprudence and political backgrounds of juvenile law, which is an outgrowth of the so-calledProgressive movement - a popular social and political movement of the late nineteenth and early twentieth century. I also trace how this socio-political cause célèbre became a fixture in Americanculture and society due to existential child labor abuses which progressive intellectuals used as a pretext to codify juvenile law in federal law and in statutory law in all 50 states by 1925. Moreover the dubious social science and Machiavellian political efforts that created the juvenile justice system out of whole cloth has done much more harm to the Constitution and to the children it was mandated to protect than any of the Progressive ideas initially envisioned rooted in Positive Law (separation of law and morals. Finally, I present am impassioned argument for congressional repeal of all juvenile case law and statutes because they are rooted in Positive Law, contrary to Natural Law (integration of law and morals, the original intent of the constitutional Framers and are therefore patently unconstitutional.

    2011-04-01

    Full Text Available The European Union Law is an unique legal phenomenon developed in the process of European integration within the framework of the European Communities and the European Union; a result of the implementation of the supranational authority of the European institutions. The European Union law is a specific legal system having independent sources and principles that developed at the border-line of international law and domestic law of the EU’s Member States. The authonomy of the European Union law is affirmed by a case-law of the Court of Justice of the European Union.The European Union has its own legal order which is separate from international law and forms an integral part of the legal systems of the Member States. The legal order of the Union is founded on various different sources of law. The different nature of these sources has imposed a hierarchy among them. At the pinnacle of this hierarchy we find primary law, represented by the Treaties and general legal principles, followed by international treaties concluded by the Union and secondary law founded on the Treaties.

    Greffet, Jean-Jacques; Brucoli, Giovanni; Sakat, Emilie; Marquier, François

    2016-01-01

    Thermal emission can be conveniently described using Kirchhoff law which states that the emissivity is equal to the absorptivity for isothermal bodies. For a finite size system, absorptivity is replaced by an absorption cross section. Here, we study the link between thermal emission and absorption by a finite size object which is not isothermal. We define a local absorption rate for a given incident plane wave and we prove that it is equal to the local emissivity rate. Hence, Kirchhoff law can be extended to anisothermal media. A practical consequence is the possibility of analysing thermal radiation by a variety of non-equilibrium systems such as microwave radiation in geophysical remote sensing or X-UV radiation by plasmas. This result provides a theoretical framework to analyse thermal emission by hot electrons in quantum wells, tunnel junctions or graphene. It paves the way to the design of a new generation of incandescent emitters made of subwavelength hot emitters coupled to cold antennas. The antennas ...

    2009-12-01

    Full Text Available The problem of influence of Community law over national criminal law is difficult to be solved even now, because criminal law is very closely related to state sovereignty. However, at European level it is a series of unifying trends in the field of criminal law. This includes: the Corpus Juris Project to develop a number of guiding principles on the protection through criminal law of financial interests of EU, within the European judiciary space; the project of founding a European Prosecutor , which would have extended jurisdiction over the entire European judicial area; at the doctrinaire level the project called ”The Criminal Code of the European Union ” result of encoding the provisions relevant for the Community criminal law and published likewise. Romanian criminal law could not remain outside these trends and this paper reveal some internal acts that reflect the trends observed at European level. Some of this acts have a direct influence, and some of them an indirect influence. An example is represented by art. 3022 of the Romanian Penal Code, which, in the basic variant, besides any operations regarding the import of wastes and residue of any kind or other dangerous goods for public health and environment, incriminates the placing or transit operations on the country without observing the laws. In this text, the phrase "without observing the laws" must be reported to both national regulations and international legal instruments.

  14. Nuclear law and law of the sea - a synthesis

    International Nuclear Information System (INIS)

    The general idea behind the work of the Paris Colloqium on Nuclear Law and Law of the Sea was that of an agreement and sometimes opposition between two specificities, that of the law of the maritime and, in particular, ocean environment, and that of the law of nuclear techniques. These relationships were studied notably in the perspective of the problems of transport of nuclear materials and their liability insurance, as well as from the viewpoint of the operation of nuclear powered ships. Another problem studied in this context is that of radioactive marine pollution. (N.E.A.)

    International Nuclear Information System (INIS)

    Extreme value theory (EVT) asserts that the Fréchet law emerges universally from linearly scaled maxima of collections of independent and identically distributed random variables that are positive-valued. Observations of many real-world sizes, e.g. city-sizes, give rise to the Zipf law: if we rank the sizes decreasingly, and plot the log-sizes versus the log-ranks, then an affine line emerges. In this paper we present an EVT approach to the Zipf law. Specifically, we establish that whenever the Fréchet law emerges from the EVT setting, then the Zipf law follows. The EVT generation of the Zipf law, its universality, and its associated phase transition, are analyzed and described in detail. (letter)

    Feminist legal theory provides a healthy skepticism toward legal doctrine and insists that we reexamine even formally gender-neutral rules to uncover problematic assumptions behind them. The article first outlines feminist legal theory from the perspectives of liberal, cultural, and radical feminism. Examples of how each theory influences legal practice, case law, and legislation are highlighted. Each perspective is then applied to a contemporary bioethical issue, egg donation. Following a brief discussion of the common themes shared by feminist jurisprudence, the article incorporates a narrative reflecting on the integration of the common feminist themes in the context of the passage of the Maryland Health Care Decisions Act. The article concludes that gender does matter and that an understanding of feminist legal theory and practice will enrich the analysis of contemporary bioethical issues.

    In tiny metallic nanostructures, quantum confinement and nonlocal response change the collective plasmonic behavior with important consequences for e.g. field-enhancement and extinction cross sections. We report on our most recent developments of a real-space formulation of an equation-of-motion that goes beyond the common local-response approximation and use of Ohm's law as the central constitutive equation. The electron gas is treated within a semi-classical hydrodynamic model with the emergence of a new intrinsic length scale. We briefly review the new governing wave equations and give examples of applying the nonlocal framework to calculation of extinction cross sections and field enhancement in isolated particles, dimers, and corrugated surfaces.

    A central goal in devising a system of courts is to make judicial services easily accessible. As a consequence, justice is usually administered in a geographically decentralized fashion: trial courts are distributed across the territory in which the jurisdiction's law is applied.

The interaction between the two is becoming increasingly important especially when the urban law is increasingly correlated with the environmental protection, the natural space and the ecological activities.

  13. Economics of mining law

    Science.gov (United States)

    Long, K.R.

    1995-01-01

    Modern mining law, by facilitating socially and environmentally acceptable exploration, development, and production of mineral materials, helps secure the benefits of mineral production while minimizing environmental harm and accounting for increasing land-use competition. Mining investments are sunk costs, irreversibly tied to a particular mineral site, and require many years to recoup. Providing security of tenure is the most critical element of a practical mining law. Governments owning mineral rights have a conflict of interest between their roles as a profit-maximizing landowner and as a guardian of public welfare. As a monopoly supplier, governments have considerable power to manipulate mineral-rights markets. To avoid monopoly rent-seeking by governments, a competitive market for government-owned mineral rights must be created by artifice. What mining firms will pay for mineral rights depends on expected exploration success and extraction costs. Landowners and mining firms will negotlate respective shares of anticipated differential rents, usually allowing for some form of risk sharing. Private landowners do not normally account for external benefits or costs of minerals use. Government ownership of mineral rights allows for direct accounting of social prices for mineral-bearing lands and external costs. An equitable and efficient method is to charge an appropriate reservation price for surface land use, net of the value of land after reclamation, and to recover all or part of differential rents through a flat income or resource-rent tax. The traditional royalty on gross value of production, essentially a regressive income tax, cannot recover as much rent as a flat income tax, causes arbitrary mineral-reserve sterilization, and creates a bias toward development on the extensive margin where marginal environmental costs are higher. Mitigating environmental costs and resolving land-use conflicts require local evaluation and planning. National oversight ensures

    We show that relativistic dynamics can be approached without using conservation laws (conservation of momentum, of energy and of the centre of mass). Our approach avoids collisions that are not easy to teach without mnemonic aids. The derivations are based on the principle of relativity and on its direct consequence, the addition law of relativistic velocities.

    2011-11-01

    Full Text Available In the pages of this study we have emphasized the relation between Law and Morals, between what is just and in just, talking thus not only about the nature of the Law and of the Morals, but also about the relation between the juridical norms and the moral principles. An evaluation of the historical process of the emergence of Law and Morals – be it brief – has enabled us to notice that the Law has evolved step by step from the Moral norms and from the customs of a moral nature, hence the conclusion that the positive juridical norms should also express, in their content, values of a moral nature. In fact, from an ontological point of view, between Law and Morals could not be a divorce, since the notions of “righteousness” and of “justice” themselves are categories of Morals. That is why the theory of juridical positivism, according to which the rule of Law can exist in the absence of Morals since the state is the only source of Law, has no credibility both from a historical and philosophical and from a juridical point of view. Finally, the increasingly higher interest of the philosophers and jurists of our time to perceive and express the content of the nature of Law adequately and, ipso facto, the relation between this one and Morals, was also determined by the international and European legislation regarding the human fundamental rights and liberties.

    2009-01-01

    During the 1970s, something deeply consequential happened in the cultural, economic, and social relationships between science and technology. Paul Forman has proposed that the abrupt reversal of the culturally ascribed primacy in the science-technology relationship circa 1980 be taken as a demarcation of postmodernity from modernity. Modernity's most basic cultural presuppositions-the superiority of theory to practice, the elevation of the public over the private and that of the disinterested over the interested, and the belief that the means sanctify the ends-were ascribed to science. In postmodernity, science is subsumed under technology, and the status of technology relative to science reflects our pragmatic-utilitarian subordination of means to ends. These cultural changes have resonated with deep epistemological and ontological changes within the sciences themselves, and all these have manifested themselves in universities becoming entrepreneurial, and the consequences thereof. Science Without Laws insightfully illustrates some of the changes within the life and human sciences by analyzing the role played by model systems and case studies.

  10. Scaling Laws in Human Language

    CERN Document Server

    Lu, Linyuan; Zhou, Tao

    2012-01-01

    Zipf's law on word frequency is observed in English, French, Spanish, Italian, and so on, yet it does not hold for Chinese, Japanese or Korean characters. A model for writing process is proposed to explain the above difference, which takes into account the effects of finite vocabulary size. Experiments, simulations and analytical solution agree well with each other. The results show that the frequency distribution follows a power law with exponent being equal to 1, at which the corresponding Zipf's exponent diverges. Actually, the distribution obeys exponential form in the Zipf's plot. Deviating from the Heaps' law, the number of distinct words grows with the text length in three stages: It grows linearly in the beginning, then turns to a logarithmical form, and eventually saturates. This work refines previous understanding about Zipf's law and Heaps' law in language systems.

    Does international medical law exist, in the first place, as an independent area of study? If so, is it urgently required in an era of comparative studies? Namely, to what extent, if at all, international studies differ from comparative ones? Besides, what are the particular characteristics of such international discipline? Namely, what are the particular features of this field that elaborate on our legal and scientific understanding in sketching possible definition for this notion of "international medical law?" In addition, how does international medical law correlate with health, ethics and health policies in our globalized world? And finally, what are the challenges that might face the international community, once the concept of "international medical law" is acknowledged? This papers aims at establishing the conceptual grounds for these questions, thus calling for the acknowledgment of a new field of study described as "international medical law".

    A polynomial algorithm.called Reduction,is presented to discover natural laws by analysing a set of experimental data.instead of a heuristic exploration which,when adopted in BACON,can only lead to rediscovering simple laws.A complex law with multiple variables involved can be discovered by reducing it to a search.This search is so efficient that it does not need any backtracking and is able to cover most of possible laws.A reduction-based discovery system,called DISCOVER 2.0,was developed with a flexible knowledge base and an ability of dealing with imperfect data.The system has been verified to be valid computationally,practically,and theoretically,by discovering a great number o complex laws,and can be also viewed as a leaming engine embodied in any intelligent systems to improve their performance by obtaining a general rule from the accumulated data.

  13. Hack's Law: Sinuosity, convexity, elongation

    Science.gov (United States)

    Willemin, James H.

    2000-11-01

    Hack's law, an empirical, power law relationship between drainage basin area and the length of the main stream channel, has long been taken to imply that drainage basins become more elongate (relatively longer and narrower) with increasing basin size. A study of the geometry of 38 basins from three distinct geomorphic settings shows that this geometric interpretation of Hack's law is only occasionally true: Even though Hack's power law relationship holds between basin area and main channel length, these basins do not necessarily become more elongate with increasing size. Rather, Hack's law is an expression of a balance between changes in basin shape and changes in channel planform geometry. For the basins in this study, changes in channel sinuosity play the most important role in this balance; changes in basin shape are far less regular. Local conditions appear to determine the partitioning of importance between changes in basin shape and channel sinuosity.

    We conjecture a novel Generalized Second Law that can be applied in cosmology, regardless of whether an event horizon is present: the generalized entropy increases monotonically outside of certain hypersurfaces we call past Q-screens. A past Q-screen is foliated by surfaces whose generalized entropy (sum of area and entanglement entropy) is stationary along one future null direction and increasing along the other. We prove that our Generalized Second Law holds in spacetimes obeying the Quantum Focussing Conjecture. An analogous law applies to future Q-screens, which appear inside evaporating black holes and in collapsing regions.

    Wilson's area law in QCD is critically examined. It is shown that the expectation value of the Wilson loop integral $ \\exp(\\int iA_\\mu dx^\\mu) $ in the strong coupling limit vanishes when we employ the conjugate Wilson action which has a proper QED action in the continuum limit. The finite value of Wilson loop with the Wilson action is due to the result of the artifact. The fact that his area law is obtained even for QED simply indicates that the area law is unphysical.

  6. Can Environmental Law be standardized

    International Nuclear Information System (INIS)

    The author makes basic considerations on standardizability both in Constitutional Law and in simple Legislative Law. He discusses in detail a key issue of Environmental Law, namely the standardization of the right of third parties affected to file suit. In painstaking detail work one has to differentiate between standards having and not having an effect which protects third parties, and how far the protection of third parties goes. The limits to standardizability are reached with the use of undetermined legal terms. The shortcomings of standardizability for the legislator could and should be made up for by the statutory power which has to reify standards in a way which could guarantee efficient execution.

    2002-01-01

    Using data from gene expression databases on various organisms and tissues, including yeast, nematodes, human normal and cancer tissues, and embryonic stem cells, we found that the abundances of expressed genes exhibit a power-law distribution with an exponent close to -1, i.e., they obey Zipf's law. Furthermore, by simulations of a simple model with an intra-cellular reaction network, we found that Zipf's law of chemical abundance is a universal feature of cells where such a network optimizes the efficiency and faithfulness of self-reproduction. These findings provide novel insights into the nature of the organization of reaction dynamics in living cells.

    Science.gov (United States)

    Azbel', Mark Ya.

    2004-10-01

    Well-protected human and laboratory animal populations with abundant resources are evolutionarily unprecedented. Physical approach, which takes advantage of their extensively quantified mortality, establishes that its dominant fraction yields the exact law, which is universal for all animals from yeast to humans. Singularities of the law demonstrate new kinds of stepwise adaptation. The law proves that universal mortality is an evolutionary by-product, which at any given age is reversible, independent of previous life history, and disposable. Life expectancy may be extended, arguably to immortality, by minor biological amendments in the animals. Indeed, in nematodes with a small number of perturbed genes and tissues it increased 6-fold (to 430 years in human terms), with no apparent loss in health and vitality. The law relates universal mortality to specific processes in cells and their genetic regulation.

    2006-09-01

    We have used friction force microscopy to probe friction laws for nanoasperities sliding on atomically flat substrates under controlled atmosphere and liquid environment, respectively. A power law relates friction force and normal load in dry air, whereas a linear relationship, i.e., Amontons' law, is observed for junctions fully immersed in model lubricants, namely, octamethylciclotetrasiloxane and squalane. Lubricated contacts display a remarkable friction reduction, with liquid and substrate specific friction coefficients. Comparison with molecular dynamics simulations suggests that load-bearing boundary layers at junction entrance cause the appearance of Amontons' law and impart atomic-scale character to the sliding process; continuum friction models are on the contrary of limited predictive power when applied to lubrication effects. An attempt is done to define general working conditions leading to the manifestation of nanoscale lubricity due to adsorbed boundary layers.

    Under the criminal law of New South Wales, the destruction of a foetus (other than in the course of a medical procedure) constitutes grievous bodily harm to the pregnant woman. Charges can be laid for offences against the woman, but not against the foetus. Many are dissatisfied with this. The Crimes Amendment (Zoe's Law) Bill 2013 (No 2) (NSW) aimed to change this by providing that a foetus is taken to be a living person for the purposes of certain offences. The Bill was strongly opposed on the basis that according personhood to a foetus in this way will have undesirable consequences that could erode the reproductive rights of women. The public debate over how the criminal law addresses the destruction of a foetus has centred on Zoe's Law. This article proposes an alternative amendment. that aims, to accommodate the concerns of the Bill's supporters and its detractors.

  6. Health Law as Social Justice.

    Wiley, Lindsay F

    2014-01-01

    Health law is in the midst of a dramatic transformation. From a relatively narrow discipline focused on regulating relationships among individual patients, health care providers, and third-party payers, it is expanding into a far broader field with a burgeoning commitment to access to health care and assurance of healthy living conditions as matters of social justice. Through a series of incremental reform efforts stretching back decades before the Affordable Care Act and encompassing public health law as well as the law of health care financing and delivery, reducing health disparities has become a central focus of American health law and policy. This Article labels, describes, and furthers a nascent "health justice" movement by examining what it means to view health law as an instrument of social justice. Drawing on the experiences of the reproductive justice, environmental justice, and food justice movements, and on the writings of political philosophers and ethicists on health justice, I propose that health justice offers an alternative to the market competition and patient rights paradigms that currently dominate health law scholarship, advocacy, and reform. I then examine the role of law in reducing health disparities through the health justice lens. I argue that the nascent health justice framework suggests three commitments for the use of law to reduce health disparities. First, to a broader inquiry that views access to health care as one among many social determinants of health deserving of public attention and resources. Second, to probing inquiry into the effects of class, racial, and other forms of social and cultural bias on the design and implementation of measures to reduce health disparities. And third, to collective action grounded in community engagement and participatory parity. In exploring these commitments, I highlight tensions within the social justice framework and between the social justice framework and the nascent health justice movement

    We show that the degree distribution of a growing network with linear preferential attachment approximately follows the Mandelbrot law,and propose an analytical method based on a recursive formula that can be used to obtain a more accurate expression of the shifting coefficient.Simulations demonstrate the advantages of our method. This work provides a possible mechanism leading to the Mandelbrot law of evolving networks,and refines the mainstream analytical methods for the shifting coefficient.

  16. Exact law of live nature

    Science.gov (United States)

    Azbel‧, Mark Ya.

    2005-08-01

    The exact law of mortality dynamics in changing populations and environment is derived. It includes no explicit characteristics of animal-environment interactions (metabolism, etc.) which are a must for life; it is universal for all animals, from single-cell yeast to humans, with their drastically different biology, evolutionary history, and complexity; it is rapidly (within few percent of life span) reversible. Such a law is unique for live systems with their homeostatic self-adjustment to environment (cf. thermodynamics of liquids and glasses). The law which is valid for all live, and only live, systems is their specific natural law. Mortality is an instrument of natural selection and biological diversity. Its law, which is preserved in evolution of all species, is a conservation law of mortality, selection, evolution, biology. The law implies new kinds of intrinsic mortality and adaptation which dominate in evolutionary unprecedented protected populations and, in contrast to species-specific natural selection, proceed via universal stepwise rungs and reduce to universal cellular mechanism. The law demonstrates that intrinsic mortality and at least certain aspects of aging are disposable evolutionary byproducts, and directed genetic and/or biological changes may yield healthy and vital Methuselah lifespan. This is consistent with experiments. Universality implies that single-cell yeast may provide a master key to the cellular mechanism of universal mortality, aging, selection, evolution, and its regulation in all animals. One may look for its manifestations in animal cells also, e.g., in their replicative senescence and cancer. Evolutionary origin and genetic nature of universality are suggested.

It is based on the idea of deactivation of the faults in the vicinity of the main shock of the earthquake. The generalization of the Omori law with the allowance for the nonstationarity of the medium in the source, which is cooling after the main shock, is presented.

  1. Teaching medical ethics and law.

    Science.gov (United States)

    Parker, Malcolm

    2012-03-01

    The teaching of medical ethics is not yet characterised by recognised, standard requirements for formal qualifications, training and experience; this is not surprising as the field is still relatively young and maturing. Under the broad issue of the requirements for teaching medical ethics are numerous more specific questions, one of which concerns whether medical ethics can be taught in isolation from considerations of the law, and vice versa. Ethics and law are cognate, though distinguishable, disciplines. In a practical, professional enterprise such as medicine, they cannot and should not be taught as separate subjects. One way of introducing students to the links and tensions between medical ethics and law is to consider the history of law via its natural and positive traditions. This encourages understanding of how medical practice is placed within the contexts of ethics and law in the pluralist societies in which most students will practise. Four examples of topics from medical ethics teaching are described to support this claim. Australasian medical ethics teachers have paid less attention to the role of law in their curricula than their United Kingdom counterparts. Questions like the one addressed here will help inform future deliberations concerning minimal requirements for teaching medical ethics.

  2. Surface Processes and Hack's law

    Science.gov (United States)

    Walcott, R.

    2010-12-01

    Hack’s law describes the non-linear relationship between the area of a catchment and the length of the longest stream within it. First described in the 1950’s based on a small area in the Appalachians, more recent studies have suggested that this relationship is consistent for over 13 orders of magnitude. As a result Hack’s law is generally considered as one of the fundamental morphological relationships of geomorphology and much effort has been devoted to understanding its origins. This law suggests that catchments are scale independent, however, recent work has demonstrated that the form of catchments varies depending on the type of surface processes operating within the catchment. In this paper we analyse the relationship between hillslope processes and Hack’s law for catchments that range over several orders of magnitude in size in the Himalaya and Chile. We show that Hack’s law varies systematically depending on the mean slope of a catchment. As the dominant process that operates within a catchment also varies with slope and scales with catchment size our findings have important implications for the robustness of Hack’s law and the scale independence of catchments.

  3. Random stress and Omori's law

    CERN Document Server

    Kagan, Yan Y

    2010-01-01

    We consider two statistical regularities that were used to explain Omori's law of the aftershock rate decay: the Levy and Inverse Gaussian (IGD) distributions. These distributions are thought to describe stress behavior influenced by various random factors: post-earthquake stress time history is described by a Brownian motion. Both distributions decay to zero for time intervals close to zero. But this feature contradicts the high immediate aftershock level according to Omori's law. We propose that these statistical distributions are influenced by the power-law stress distribution near the earthquake focal zone and we derive new distributions as a mixture of power-law stress with the exponent psi and Levy as well as IGD distributions. Such new distributions describe the resulting inter-earthquake time intervals and closely resemble Omori's law. The new Levy distribution has a pure power-law form with the exponent -(1+psi/2) and the mixed IGD has two exponents: the same as Levy for small time intervals and -(1+...

    Full Text Available Modern law has shifted towards a positivistic mode of reasoning,and is the instrument of a form of politics that claims wide‐ranging rights of control. In combination with an increase of environmental complexity, law is impacted strongly. It is quantitatively extended, thereby losing its normative power. A globalization of world conditions enters the situation as a new factor. As law has the ability to globalize itself, whereas politics can only do so in a limited way (not a world state, possibilities for a partial re‐disengagement of law from politics result from this. Law is now able to face politics more strongly from a basis of legitimization that is independent from politics.Das Recht der Moderne ist auf den Begründungsmodus der Positivität umgestellt, und es ist Instrument einer Politik mit weitreichendem Steuerungsanspruch. In Kombination mit einer Steigerung der Umweltkomplexität ergibt sich daraus für das Recht eine starke Belastung. Es wird quantitativ ausgedehnt, an normativer Kraft aber eher ärmer. Als neuer Faktor tritt die Globalisierung der Weltverhältnisse in diese Situation ein. Da das Recht sich globalisieren kann, die Politik aber nur begrenzt (kein Weltstaat, ergeben sich daraus Möglichkeiten der partiellen Wiederabkoppelung des Rechts von der Politik. Das Recht könnte der Politik von politikunabhängigen Legitimationsgrundlagen her verstärkt wieder eigenständig gegenübertreten .

  7. Nuclear law and disorder

    International Nuclear Information System (INIS)

    One would like to say that world attention will be focussed on the 2005 Review Conference of the Nuclear Non-Proliferation Treaty (NPT), that governments will rush to implement the 13 Practical Steps to nuclear disarmament already agreed on, that the combined actions of the political and civil order will greatly reduce the present high level of danger of the use of nuclear weapons. Unfortunately, in the real world of political disorder that we live in, none of this is likely to occur. There is no doubt in my mind that the present crisis is the worst the NPT has experienced. The treaty is on the verge of collapse, and the proliferation of nuclear weapons, both among those who already have them and those who want them, is staring us in the face. It is truly shocking that the public knows so little about the nature of the danger and that governments, for the most part, are so desultory in their approach to the upholding of law. While NPT meetings have never been free of conflict, the battles of the past were frequently patched over by an application of goodwill and a minimum show of trust. Now the goodwill and trust are gone largely because the nuclear-weapons States (NWS) have tried to change the rules of the game. Adherence to that bargain enabled the indefinite extension of the treaty in 1995 and the achievement of an 'unequivocal undertaking' in 2000 toward elimination through a programme of 13 Practical Steps. Now the US is rejecting the commitments of 2000 and premising its aggressive diplomacy on the assertion that the problem of the NPT lies not in the NWS's own actions but in the lack of compliance by States such as North Korea and Iran. Brazil bluntly warned: 'The fulfillment of the 13 steps on nuclear disarmament agreed during the 2000 Review Conference have been significantly - one could even say systematically - challenged by action and omission, and various reservations and selective interpretation by Nuclear Weapon States.'

  13. The molecular concept of law

    Directory of Open Access Journals (Sweden)

    Hendrik Gommer

    2011-04-01

    Full Text Available In his famous work The Concept of Law Hart asked himself the question 'what is law?' Hart makes a very strict distinction between rules and morals: morals are rooted in biology, rules source back to society. Hart's sociological truisms have proven to be untrue, because modern evolutionary biology is not about the survival of the individual (or even of a species but about the spreading of genes. This knowledge changes the fundamentals of Hart's theory and therefore his theory as a whole. In addition, my theory captures vital insights of Dworkin, legal realism, Posner and CLS, while at the same time forming a significant improvement upon them.In essence, the biological theory of law presented in this article is based on fractal patterns. Macroscale patterns recur in microscale patterns. The spreading of genes depends on important characteristics of genes: they are stable, they replicate, they need nutrients to replicate and they can cooperate. Superficially, genes, cells, organisms and groups may seem to act purposefully, but it is merely a pattern, with genes as generators, that brings structure to chaos. Human desires are in fact the needs of their genes. Thanks to language, morals can be put in words and become rules. To keep everyone working together, we need an ingenious device - like the law - to maintain that complex situations can continue to be judged on the basis of the simple principle of stability and reciprocity. To a degree, therefore, law itself can be derived from unconscious emotions and morals.

  14. Three laws of energy transitions

    International Nuclear Information System (INIS)

    The paper formulates and explores a hypothesis on three general energy transition laws: the law of stable long-term energy costs to income ratio; the law of improving energy quality; and the law of growing energy productivity. These laws are essential for shaping long-term projections and checking for their consistency. All three are rooted in amazingly stable in time and universal across countries energy costs to income ratios. Limited energy purchasing power sets up thresholds, which, if exceeded, bring asymmetry to energy demand to price elasticity. The author believes, that the theoretical postulate on the substantial substitution among production factors, which is used in the production functions theory, may be incorrect. In reality, innovations mainly lead to the substitution of a low-quality production factor with the same yet of a better-quality. Improving energy quality with stable costs to income ratio is accompanied by growing energy productivity. Energy costs to income thresholds are indicators allowing for better projections of oil prices

  16. On the integration of public law jurisprudence

    2006-01-01

    After two to three hundred years of development,modern public laws have become more and more important,mature and integrated especially since the 20th century.Traditionally,the dispersive and overlapping public law researches were grounded on the sectional public laws like constitutional law,administrative law,criminal law,procedural law,international public law,etc.Nevertheless,with all-around emergence of public law,the traditional research method can no longer adapt to the development needs of the modern public law.Therefore,it is quite necessary for us to create a kind of moderate unified public law between the laws and the sectional public laws,so as to do comprehensive,integrated and systematic researches on various sectional public laws.Based on the indepth argumentation about the necessity of developing unified public laws,this paper further puts forward that,to discuss an all-encompassing way about the main problems of creating the unified public laws and expect to fill the gap with it,the unified public law should define its study objectives mainly focused on the contents of integrated public law criteria,common public law features and general public law rules and so on;form its theoretical basis on the line of the relations between public power and the citizen privilege;establish its category structure found on the concept of public power and the derivative core and basic categories;and build up the disciplinary system based on the systematic integrity of the public law research results.

  7. A new Newton's law of cooling?

    Science.gov (United States)

    Kleiber, M

    1972-12-22

    Several physiologists confuse Fourier's law of animal heat flow with Newton's law of cooling. A critique of this error in 1932 remained ineffective. In 1969 Molnar tested Newton's cooling law. In 1971 Strunk found Newtonian cooling unrealistic for animals. Unfortunately, he called the Fourier formulation of animal heat flow, requiring post-Newtonian observations, a "contemporary Newtonian law of cooling."

  10. Drought, Sustainability, and the Law

    Directory of Open Access Journals (Sweden)

    Robert W. Adler

    2010-07-01

    Full Text Available Researchers and responsible officials have made considerable progress in recent years in efforts to anticipate, plan for, and respond to drought. Some of those efforts are beginning to shift from purely reactive, relief-oriented measures to programs designed to prevent or to mitigate drought impacts. Considerably less attention has been given to laws that may affect practices and policies that either increase or decrease drought vulnerability. Water law regimes, drought response and relief legislation, and laws governing broader but related issues of economic policy—especially agricultural policy—should be evaluated more comprehensively to enhance incentives for more ―water sustainable‖ practices in agriculture and other sectors of the economy. Those changes will be increasingly important if current climate change models are correct in their prediction that many parts of the world can expect more frequent and more severe conditions of meteorological drought in the ensuing decades.

  11. Zipf Law for Brazilian Cities

    CERN Document Server

    Moura, N J; Jr., Newton J. Moura; Ribeiro, Marcelo B.

    2006-01-01

    This work studies the Zipf Law for cities in Brazil. Data from censuses of 1970, 1980, 1991 and 2000 were used to select a sample containing only cities with 30,000 inhabitants or more. The results show that the population distribution in Brazilian cities does follow a power law similar to the ones found in other countries. Estimates of the power law exponent were found to be 2.22 +/- 0.34 for the 1970 and 1980 censuses, and 2.26 +/- 0.11 for censuses of 1991 and 2000. More accurate results were obtained with the maximum likelihood estimator, showing an exponent equal to 2.41 for 1970 and 2.36 for the other three years.

    2008-01-01

    The paper presents a simple derivation of the Gustafson-Barsis law from the Amdahl's law. In the computer literature these two laws describing the speedup limits of parallel applications are derived separately. It is shown, that treating the time of the execution of the sequential part of the application as a constant, in few lines the Gustafson-Barsis law can be obtained from the Amdahl's law and that the popular claim, that Gustafson-Barsis law overthrows Amdahl's law is a mistake.

  15. Two Concepts of Law of Nature

    2013-01-01

    I argue that there are at least two concepts of law of nature worthy of philosophical interest: strong law and weak law. Strong laws are the laws investigated by fundamental physics, while weak laws feature prominently in the “special sciences” and in a variety of non-scientific contexts. In the first section, I clarify my methodology, which has to do with arguing about concepts. In the next section, I offer a detailed description of strong laws, which I claim satisfy four criteria: (1) If it...

    2011-04-01

    Full Text Available This paper discusses the online Juris Doctor Program (JD Program at RMIT University. The first part of the paper provides a brief overview of the JD Program, the graduate capabilities of the Program and key principles associated with the teaching of law to online postgraduate students. In line with the literature in the area of online teaching and learning, it is argued that online education needs to facilitate deep learning and needs to be based on principles relating to student engagement and active participation.The second part of the paper showcases some of the courses that are taught on an online basis in the JD Program. A blended approach is adapted to the teaching of the advocacy as well as the Negotiation and Dispute Resolution courses. The Contracts Law course adopts a conversational framework to engage online law students. In discussing the online teaching and assessment practices in this course, the paper demonstrates how the teaching and assessment practices in these courses enhance deep learning and graduate skills and attributes essential for law students through premising the activities on principles relating to active learning and deep learning.

  2. Thermodynamic laws in isolated systems.

    Science.gov (United States)

    Hilbert, Stefan; Hänggi, Peter; Dunkel, Jörn

    2014-12-01

    The recent experimental realization of exotic matter states in isolated quantum systems and the ensuing controversy about the existence of negative absolute temperatures demand a careful analysis of the conceptual foundations underlying microcanonical thermostatistics. Here we provide a detailed comparison of the most commonly considered microcanonical entropy definitions, focusing specifically on whether they satisfy or violate the zeroth, first, and second laws of thermodynamics. Our analysis shows that, for a broad class of systems that includes all standard classical Hamiltonian systems, only the Gibbs volume entropy fulfills all three laws simultaneously. To avoid ambiguities, the discussion is restricted to exact results and analytically tractable examples. PMID:25615053

    2016-07-01

    We report the experimental observation of Snell's law for magnetostatic spin waves in thin ferromagnetic Permalloy films by imaging incident, refracted, and reflected waves. We use a thickness step as the interface between two media with different dispersion relations. Since the dispersion relation for magnetostatic waves in thin ferromagnetic films is anisotropic, deviations from the isotropic Snell's law known in optics are observed for incidence angles larger than 25 ° with respect to the interface normal between the two magnetic media. Furthermore, we can show that the thickness step modifies the wavelength and the amplitude of the incident waves. Our findings open up a new way of spin wave steering for magnonic applications.

    Hendrik Gommer

    2011-01-01

    In his famous work The Concept of Law Hart asked himself the question 'what is law?' Hart makes a very strict distinction between rules and morals: morals are rooted in biology, rules source back to society. Hart's sociological truisms have proven to be untrue, because modern evolutionary biology is not about the survival of the individual (or even of a species) but about the spreading of genes. This knowledge changes the fundamentals of Hart's theory and therefore his theory as a whole. In a...

    1999-01-01

    One of the main activities in science teaching, and in particular in Physics teaching, is not only the discussion of both modern problems and problems which solution is an urgent matter. It means that the picture of an active and alive science should be transmitted to the students, mainly to the College students. A central point in this matter is the issue which characterizes the Fundamental Laws of Nature. In this work we emphasize that this sort of laws may exist in areas which are different from those usually considered. In this type of discussion it is neither possible nor desirable to avoid the historical perspective of the scientific development.

    Directory of Open Access Journals (Sweden)

    William R.G. Loader

    2011-06-01

    Full Text Available This article revisited the issue of Jesus’ attitude towards the Torah on the basis of a critical discussion of the most recent extensive treatment of the theme by Meier in his A marginal Jew: Rethinking the historical Jesus: Volume four: Law and love (2009. It engaged Meier’s contribution in the light of contemporary research, concluding that, whilst Meier provided an erudite analysis, his thesis that Jesus’ teaching on divorce and oaths revoked Mosaic law did not convince, for it did not adequately consider the extent to which the contemporary interpretation of the Torah could encompass such radicalisation.

  12. Tempered stable laws as random walk limits

    OpenAIRE

    Chakrabarty, Arijit; Meerschaert, Mark M.

    2010-01-01

    Stable laws can be tempered by modifying the L\\'evy measure to cool the probability of large jumps. Tempered stable laws retain their signature power law behavior at infinity, and infinite divisibility. This paper develops random walk models that converge to a tempered stable law under a triangular array scheme. Since tempered stable laws and processes are useful in statistical physics, these random walk models can provide a basic physical model for the underlying physical phenomena.

  17. Legal certainty and Commercial Law: a comparative perspective (common law x civil law

    Directory of Open Access Journals (Sweden)

    Fábio Ulhoa Coelho

    2015-06-01

    Full Text Available The purpose of this article is to discuss the issue of legal certainty. It reviews the legal certainty in the ambit of Brazilian Law, a civil law jurisdiction. The concept of legal certainty is delimited and its importance for economy and commercial relations is discussed. The most important aspect of legal certainty is “ideology”. The judicial legitimacy of the same-sex family union in Brazil is a highly notable case in which we can see that a norm is interpreted differently when the ideology changes. As “ideology matters”, if a country wants to provide more legal certainty, it has to develop actions aiming at changing the ideology. The conclusion suggests the thesis that ideology would be the most important aspect in the matter of legal certainty also in common law jurisdictions.

    In EU law, nationality and gender were the only equality issues on the legal agenda from the outset in 1958 and for about 40 years. Multiple discrimination was not addressed until the 1990's. The intersectionality approach which has been widely discussed outside Europe has mainly been used...

  16. Predictive implications of Gompertz's law

    Gompertz's law tells us that for humans above the age of 35 the death rate increases exponentially with a doubling time of about 10 years. Here, we show that the same law continues to hold up to age 106. At that age the death rate is about 50%. Beyond 106 there is so far no convincing statistical evidence available because the number of survivors are too small even in large nations. However, assuming that Gompertz's law continues to hold beyond 106, we conclude that the mortality rate becomes equal to 1 at age 120 (meaning that there are 1000 deaths in a population of one thousand). In other words, the upper bound of human life is near 120. The existence of this fixed-point has interesting implications. It allows us to predict the form of the relationship between death rates at age 35 and the doubling time of Gompertz's law. In order to test this prediction, we first carry out a transversal analysis for a sample of countries comprising both industrialized and developing nations. As further confirmation, we also develop a longitudinal analysis using historical data over a time period of almost two centuries. Another prediction arising from this fixed-point model, is that, above a given population threshold, the lifespan of the oldest persons is independent of the size of their national community. This prediction is also supported by empirical evidence.

  18. [Forensic psychiatry and Islamic law].

    Islam is the second most popular monotheistic religion in the world. Its followers, the Muslims, are about 1.2 billion people and are the majority in 56 countries around the globe. Islam is an holistic way and model of life and its rules, according to a large proportion of Muslims, should have more power than the laws deriving from any secular authority. This means that the divine laws, as depicted from Islam's holy scripts, should be the laws of the land. In the strict Islamic states, as Saudi Arabia, the Islamic law or the Shari'ah prevails. Shari'ah means the path, the road each faithful Muslim should follow according to the rules of God. The Islamic views on mental health have some interesting characteristics: on the one hand, the moral necessity for the protection and care of the vulnerable individuals is very strong, but on the other hand superstitions and stigmatization influence the peoples' attitude against mental health patients. At the beginning of its historical course, Islamic world was a pioneer concerning mental health care. Unfortunately, as time passed by, we have observed considerable regression. In our days mental health services provided in most of the Islamic states cannot be considered adequate according to modern Western standards. The same course characterizes the Forensic Psychiatric services and the relevant legislation in the Islamic world.

    The purpose of this article is to discuss the issue of legal certainty. It reviews the legal certainty in the ambit of Brazilian Law, a civil law jurisdiction. The concept of legal certainty is delimited and its importance for economy and commercial relations is discussed. The most important aspect of legal certainty is “ideology”. The judicial legitimacy of the same-sex family union in Brazil is a highly notable case in which we can see that a norm is interpreted differently when the ideolog...

  5. European Energy Law. Report IV

    2007-07-01

    The European Energy Law Report IV presents an overview of the most important legal developments in the field of EU and national energy law as discussed at the 2006 European Energy Law Seminar. It examines recent developments in EU and National Law affecting the energy sector. This includes the increasing use of EU competition law to liberalise the energy markets, the long-awaited implementation of the 2003 Electricity and Gas Directives in Germany and an assessment of Regulation 1775/2005 and its effect on the European gas market. Besides the energy market liberalisation, the Community is increasingly paying attention to the need for a sustainable and clean energy supply. The second part of the book therefore includes chapters on legal issues resulting from the experiences on emission trading in 2005-2007, the regulatory challenges resulting from the new Commission Energy Policy, the impact of the Amsterdam and Berlin Fora on EU Energy policy, and the EU policy framework on energy efficiency. An important tool for improving energy efficiency is the introduction of white certificates. The third part of the report presents the basic principles of white certificates as well as practical experiences and policies in some member states like Italy, France, The Netherlands and the UK. The final part of the report considers several issues related to the development and use of subsea electricity interconnectors and pays special attention to the development of the NorNed cable. It raises the need for a Treaty perspective on the developments of such subsea interconnectors. Then some regulatory views on the development of the NorNed cable and market coupling through the cable are presented. Finally, the economic and regulatory distinction between regulated and merchant interconnectors is discussed.

    Full Text Available The development of Indonesian contract law has been influenced by enacment of new law, court verdicts and legal practices. It has been influenced by civil law and common law systems applied in other countries as well. The enacment of Consumer Protection Act strenghtens position of consumers against profesional seller. The Basic Agrarian Law and its Implementation Laws improve certainty in ownership of land. Courts have recognized, the doctrine of undue influence, acceptance by conduct, but they have not recognized pre contractual liability and have not applied the doctrine of unjustified enrichment in disputes regarding illegal contract. As practical matter, the integration clause under common law system stipulated in contract governed by Indonesian law, whereas Internasional Convention on Sale of Good regarding this issue adopts civil law system.

  7. Laws of reflection and Snell's law revisited by video modeling

    2014-07-01

    Video modelling is being used, nowadays, as a tool for teaching and learning several topics in Physics. Most of these topics are related to kinematics. In this work we show how video modelling can be used for demonstrations and experimental teaching in optics, namely the laws of reflection and the well-known Snell's Law of light. Videos were recorded with a photo camera at 30 frames/s, and analysed with the open source software Tracker. Data collected from several frames was treated with the Data Tool module, and graphs were built to obtain relations between incident, reflected and refraction angles, as well as to determine the refractive index of Perspex. These videos can be freely distributed in the web and explored with students within the classroom, or as a homework assignment to improve student's understanding on specific contents. They present a large didactic potential for teaching basic optics in high school with an interactive methodology.

    The production, the commerce and the use of drugs and other substances are ruled by several conventions of international law, that, at first, have had as object the production and the commerce of drugs for lawful purposes, and the measures required to prevent and to repress, at certain conditions, abuses and unlawful traffics. Just more recently, following some solicitations noticed by the International Community, and according to the concept of "well-balanced approach" described in the text, the measures introduced in this way were supported by a more incisive international movement, fit for the repression of unlawful traffics of drugs and to the adoption of suitable measures of prevention, also to avoid, at national level, sanitary, social and economical implications of the criminal phenomenon.

    Despite more than a century of research by psychologists on issues relating to the law, most such research has focused on a small subset of topics relevant to the legal system. Here, I review several legal topics amenable to psychological research that fall under the broad umbrella of property law: (1) how the concepts of property and ownership are represented cognitively; (2) the relationship between wealth and happiness, consumer behavior, and the priming effect of money concepts; (3) animal and child development in cognition about and behavior toward property and ownership; and (4) the relevance of psychological research on home to legal policy. These and other areas provide potential research agendas for cognitive and social cognitive psychologists. After noting the importance of such research for legal doctrine, theory, and policy, I close with suggestions for effectively communicating empirical findings to the legal community. PMID:20382918

    1961-02-01

    A multiplicative selection rule for mu meson-electron transitions is proposed. A "muon parity" = -1 is considered for the muon and its neutrino, while the "muon parity" for all other particles is +1. The selection rule then states that (-1) exp(no. of initial (-1) parity particles) = (-1) exp(no. of final (-1) parity particles). Several reactions that are forbidden by an additive law but allowed by the multiplicative law are suggested; these reactions include mu{sup +} .> e{sup +} + nu{sub mu} + {ovr nu}{sub e}, e{sup -} + e{sup -} .> mu{sup -} + mu{sup -}, and muonium .> antimuonium (mu{sup +} + e{sup -} .> mu{sup -} + e{sup +}). An intermediate-boson hypothesis is suggested. (T.F.H.)

    The arranged marriages of 210 young people in Yongle Town in Zunyi County of Guizhou Province were dissolved in 1995. The proportion of child betrothals, which generally happens among close relatives, is as high as 85% in the town. Some engagements, known as fetus betrothals or belt betrothals, are arranged before the children are born or while they are still infants strapped (belted) to their mothers. Dissemination of information from the Constitution, the Marriage Law, and the Regulations on the Registration of Marriage concerning marriage, healthier births, and good upbringing of children, and other information on reproductive health, has shown young people that they have the freedom to love and marry of their own free will, that their marriage is protected by law, and that consanguineous marriage is harmful to the health of future generations. Some convinced their parents that their arranged marriages should be annulled.

    Full Text Available The progress in the life sciences and medicine driven by modern advances and discoveries of science and technology has led to the development of assisted reproductive technology as a solution to the problem of infertility, replacing adoption as a traditional alternative to biological parenthood. In this context, deserves special mention surrogacy by the disputes generated from a social standpoint, ethical, legal and biomedical. The disparate regulation of this practice into national law has led to the “reproductive tourism”, that is, the transfer of couples from countries where the practice of surrogacy is illegal in other countries where the practice is legal, leading private international law issues relating to the recognition of the parentage of children born through the use of these techniques.

    The aim of this article is to describe the circumcision procedure during history, its therapeutic and preventive goals, with focus on bioethical, economic and law issues. The origins of this practice are lost in antiquity. It was performed since 3000 BC by the Egyptians for hygienic and religious reasons. Moreover, male circumcision is a religious commandment in Judaism and Islam, and it is customary in some Oriental Orthodox and other Christian churches of Africa. Nowadays, circumcision is performed as a routine procedure by the Jews and the Muslims for religious reasons. The world prevalence of men with circumcision is 12.5-33%, especially in USA, Canada, Islamic people and Africa; in Europe the prevalence rate is low (in Great Britain it is 1.5%). Currently, male circumcision is being highly debated because of ethical, law and scientific issues and the different roles of this procedure: therapeutic, prophylactic (but there is no universal consensus) and ritualistic role. Nowadays, in Italy there is a strong debate about the consensus for this practice and its indications. The Italian law does not allow performing ritualistic circumcision, as a free of charge procedure in public hospitals, at the government's expenses, because the Italian law must protect different religious cultures, in name of the laity of the State. Thus, national bioethical committee (CNB) has established that ritualistic circumcision may only be performed on a paying basis in public hospitals. As a protective practice, circumcision has decreased in the entire world because of the improvement of hygienical conditions and, above all, the lack of unanimous consent on the real usefulness of protective circumcision, even if several studies have recently demonstrated the protecting role of male circumcision against HIV infection.
