Abstract. We study main parameters of earthquakes from the perspective of the first digit phenomenon: the nonuniform probability of the lower first digit different from zero compared to the higher ones. We found that source parameters like coseismic slip distributions at the fault and coseismic inland displacements show first digit anomaly. We also found the tsunami runups measured after the earthquake to display the phenomenon. Other parameters found to obey first digit anomaly are related to the aftershocks: we show that seismic moment liberation and seismic waiting times also display an ano

Surface tension is an important property of liquid, the bulk surface tension concept changes considerably when minute volume of a given liquid (drop let radius<10nm) is considered. Although an extensive thermodynamical treatment and theoretical basis have been considered in the past on the curvature dependence of surface tension, yet its experimental evaluation is deemed necessary and it has been shown hither to that positronium annihilation parameters serve faithfully to this purpose. However, the drastic lowering of surface tension with the dispersion of surfactant in the liquid phase dis

Abstract:

A dynamic model is established to investigate tombstoning phenomenon of passive SMT components during reflow. This model consists of three dynamic equations for the motion of the component and four nonlinear algebraic equations for area conservation, constant curvatures for solder fillets, and solder height-length relations. The formulation neglects the gravity effect in the solder. It is shown that formation of tombstoning depends on a combination of parameters such as component geometry, pad sizes, gap size between pads, molten solder volume and properties, and contact angles.

Abstract We use from in distribution of the equations for a non viscous, incompressible liquid. Using the Dirac filtering property some integral equations were obtained, giving the liquid velocity and pressure fields due to the bubble’s implosion. The difficulties derive from the fact that the system of differential equations with partial derivates is non-linear and the distribution in the spherical coordinates depends on several parameters. The most important criterion, decisive in the cavitation process, is the one in which the vaporization pressure intervenes pv.

The character and authenticity of the Czech beer, which has been accorded the protected geographical indication (PGI) Česk&eacute; pivo by the EU, are based on specific technology and use of unique raw materials. A number of chemical and sensorial markers of the Czech beer differ from those of other lager or Pils-type beers. The majority of Czech beers contain residual (unfermented) extract. One of the most typical characteristics of Czech beers is the difference in attenuation; its long-term recorded limit value is 4.5%. Another important characteristic typical of the Czech beer is bitter

When there exist certain kinds of matching in an electric system between the nonlinear input and noise, amplifying the input noise may dramatically increase the output SNR other than decrease it. And stochastic resonance is a phenomenon that when noise is input at certain amplitude the output SNR reaches its peak. Generalized stochastic resonance is the kind of nonlinear phenomena that the output (output SNR, output mean value, etc.) is a non-monotonic function of some parameter of noise (amplitude, correlation time) or input (amplitude, frequency).

Abstract:

Switching phenomenon of the bathtub vortex in a double-orifice water tank is experimentally investigated. This alternation between “vortexflow” and “nonvortex flow” is caused by flow rate differences through the two orifices. The oscillation frequency is experimentally examined by changing the design parameters, such as the orifice size, the distance between two orifices, and the fluid level. A linear relationship is obtained between the frequency and the flow rate difference.

This note considers a puzzling phenomenon that is observed in some semiparametric estimation problems.

This phenomenon takes place even in cases of semi-nonparametric models in which the nuisance parameters are infinite-dimensional and cannot be estimated at the parametric rate. We examine the structure and present the necessary and sufficient condition for the occurrence of this puzzle. We also provide a simple sufficient conditio

Abstract:

Turbulent macro-instabilities in the process of mixing in cylindrical baffled vessel provided with pitched blade impeller were studied. Rules of macro-instability occurrence were investigated in their dependence on physical parameters of three Newtonian liquids mixed and on the regime of mixing. The observations were realized partly visually, partly by means of a specially designed mechanical measuring device connected with an electronic recorder indicating the manifestations of instability in the liquid.

Abstract:

Russia is the only country in the G20 group of nations where Donald Trump is the preferred choice for the next President of the United States. This article examines a hypothesis that Trump owes his popularity in Russia to the way Russian media frames his image. The media content was analyzed by quantitative parameters and then, these parameters were further complimented with a discourse analysis which, in addition to examining the texts themselves, also appeals to the reality beyond the texts, including social and political circumstances that surround the issue. The results demonstrate that th

Abstract:

The authors analyze street-level corruption as a complex criminological phenomenon. They use the methods of statistical, comparative law and correlation analysis to examine the dynamics of street-level bribery, outline its conceptual borders and identify the key criminological parameters and characteristics of bribery. The presented corruption indicators (street-level corruption type, corruption-infestation index of state and local authorities, structure of bribery and transactional costs index) make it possible to widen the borders of criminological research of street-level bribery, introduce

Abstract:

In this paper we introduce a variation on Glaser's method for determining the shape of the failure rate function of a mixture. It has often been seen that the shape of the failure rate depends on the mixing parameter q. Our method provides an explanation for this phenomenon. We then illustrate our technique with the mixture of an exponential and a gamma density for all possible cases.

Abstract:

Excessive scaling is one of the main nuisances in relation to the use of drinking water. Ever more water companies try to minimise scaling. Although scaling is an old problem, prediction of scaling has been proven to be very tricky. Traditionally, the (Langelier) Saturation Index is used to evaluate scaling properties of drinking water. From experience it is well known that this parameter is not suitable for proper prediction. New parameters have been developed and standardised for scaling prediction, namely the Calcium Carbonate Precipitation Potential, calculated at a temperature of 90°C (CC

Abstract:

Frieze patterns (in the sense of Conway and Coxeter) are related to cluster algebras of type A and to signed continuant polynomials. In view of studying certain classes of cluster algebras with coefficients, we extend the concept of signed continuant polynomial to define a new family of friezes, called c-friezes, which generalises frieze patterns. Having in mind the cluster algebras of finite type, we identify a necessary and sufficient condition for obtaining periodic c-friezes. Taking into account the Laurent phenomenon and the positivity conjecture, we present ways of generating c-friezes o
