The table presented permits determination of the number of teeth and their displacement coefficients, thus ensuring conditions for a satisfactory operation of the differential gears. 查看全文

22   New recursion formula used in the matrix of the direction cosine in the strapdown inertial navigation and guidance system New recursion formula used in the matrix of the direction cosine in the strapdown inertial navigation and guidance system    2006 Quaternion method, which has been successfully applied to the Strapdown Inertial Navigation and Guidance for tens year, is classical. In general, the practical using of the direction cosine matrix relating body frame. to navigation frame. is essential. However, the quaternion, which is only impermanent variable, can be leaved out. So the paper proposes a new recursion algorithm for the direction cosine matrix without quaternion. Mathematical simulation shows that the algorithm based on the diffe... 查看全文

23   Differentiating the higgs boson from the dilaton and radion at hadron colliders Differentiating the higgs boson from the dilaton and radion at hadron colliders    2012 A number of candidate theories beyond the standard model (SM) predict new scalar bosons below the TeV region. Among these, the radion, which is predicted in the Randall-Sundrum model, and the dilaton, which is predicted by the walking technicolor theory, have very similar couplings to those of the SM Higgs boson, and it is very difficult to differentiate these three spin-0 particles in the expected signals of the Higgs boson at the LHC and Tevatron. We demonstrate that the observation of the rat... 查看全文

26   New operator splitting method for the numerical solution of partial differential equations New operator splitting method for the numerical solution of partial differential equations    1995 We present a new method of operator splitting for the numerical solution of a class of partial differential equations, which we call the odd-even splitting. This method extends the applicability of higher-order composition methods that have appeared recently in the literature. These composition methods can be considerably more efficient than conventional methods and additionally require at least a factor of two less storage capacity. In the case of Hamiltonian partial differential equations the ... 查看全文

27   New approach to geometric profiling of the design elements of the passage part in turbo-machines New approach to geometric profiling of the design elements of the passage part in turbo-machines    1994 In designing highly economical up-to-date aviation turbo-machines, specific requirements for structural elements, contacting a working medium, should be met. For this purpose, at the preliminary design stage, some support points of the contours of pieces are calculated. Further, a corresponding function discreetly specified is interpolated.

29   Randomized Rendez-Vous . . . Randomized Rendez-Vous . . . Evangelos Kranakis, Danny Krizanc, Pat Morin    0 We present a tradeoff between the expected time for two identical agents to rendez-vous on a synchronous, anonymous, oriented ring and the memory requirements of the agents. In particular, we show there exists a 2t state agent, which can achieve rendez-vous on an n node ring in expected time O(n 2 /2 t + 2 t) and that any t/2 state agent requires expected time ?(n 2 /2 t). As a corollary we observe that Θ(log log n) bits of memory are necessary and sufficient to achieve rendez-vous in linear ti... 查看全文

36   Free Probability Theory And Random Matrices Free Probability Theory And Random Matrices Roland Speicher    0 Free probability theory originated in the context of operator algebras, however, one of the main features of that theory is its connection with random matrices. Indeed, free probability can be considered as the theory providing concepts and notations, without relying on random matrices, for dealing with the limit N !1 of N N-random matrices. One of the basic approaches to free probability, on which I will concentrate in this lecture, is of a combinatorial nature and centers around so-called fre... 查看全文

39   NEW METHOD FOR THE EFFICIENT NUMERICAL INTEGRATION OF THE SYSTEM OF ORDINARY DIFFERENTIAL EQUATIONS FROM THE ANALYSIS OF LOSS-OF-COOLANT ACCIDENTS. NEW METHOD FOR THE EFFICIENT NUMERICAL INTEGRATION OF THE SYSTEM OF ORDINARY DIFFERENTIAL EQUATIONS FROM THE ANALYSIS OF LOSS-OF-COOLANT ACCIDENTS.    1973 The simulation of loss-of-coolant accidents with the aid of multinode point models requires the stepwise numerical solution of a system of nonlinear ordinary differential equations for pressure, enthalpy, mass and massflow. In this paper a combination of an implicit and an explicit formula in conjunction with an extrapolation algorithm is introduced. It has proved to be an efficient numerical technique for the integration of the system mentioned. 查看全文

42   Hidden Cues in Random Line Stereograms Hidden Cues in Random Line Stereograms H. K. Nishihara, T. Poggio    1983 Successful fusion of random-line stereograms with breaks in the vernier acuity range has been previously interpreted to suggest that the interpolation process underlying hyperacuity is parallel and preliminary to stereomatching. In this paper (a) we demonstrate with computer experiments that vernier cues are not needed to solve the stereomatching problem posed by these stereograms and (b) we provide psychophysical evidence that human stereopsis probably does not use vernier cues alone to achie... 查看全文

48   On the development of fluid models of the differential type within a new thermodynamic framework On the development of fluid models of the differential type within a new thermodynamic framework    2008 We assess the status of a fluid of grade two within the context of a new thermodynamic framework that has been put into place that appeals to the maximization of the rate of entropy production for making a choice of constitutive equations from an admissible set. Unlike fluid of the rate type like the Maxwell fluid, the Oldroyd-B fluid or Burgers' fluid, we see that certain modifications need to be made if we have to accommodate differential type fluids such as fluids of grade two. © 2008. 查看全文
