in this paper, a compound binomial risk model in the presence of a constant dividend barrier is studied. two types of individual claims, main claims and by-claims, are defined, where every by-claim is induced by the main claim randomly and may be delayed for one time period with a certain probability. in the evaluation of the moments of the present value of dividends, the interest rates are ass...

We point out that quantum field theories based on the concept of Clifford space and Clifford algebra valued-fields involve both positive and negative energies. This is a consequence of the indefinite signature (p, q) of the Clifford space. When the signature is neutral, p = q, then vacuum energy vanishes and there is no cosmological constant problem. A question of the stability of such theories...

a new integrated model is developed for information systems planning. in this model, entitled hisspm, a combination of the strengths of critical success factors (csf) method, analytic hierarchy process (ahp) technique and genetic algorithms (ga) is used to identify and prioritize the required information systems. this model considers both qualitative and quantitative factors, as well as the imp...

A Bayesian statistical model to simultaneously characterize two or more social networks defined over a common set of actors is proposed. The key feature the hierarchical prior distribution that allows user represent entire system jointly, achieving compromise between dependent and independent networks. Among others things, such specification provides an easy way visualize multilayer network dat...

A new model IS proposed for the low-frequency plezoelectnc acttvlty of ZnO films grown on CVD BO, In this MOS structure, wth ZnO as the sermconductor, a depletion layer is induced by means of a d c has voltage Usmg standard semiconductor theory, an expression 1s derived relating the electnc field m tis depletion layer mth the dnvmg a c and d c voltages Due to the built-m charge at the ZnO-StO, ...

We present the formalism and numerical results for torsional oscillations of relativistic stars endowed with a strong dipole magnetic field, assumed to be confined to the crust. In our approach, we focus on axisymmetric modes and neglect higher-order couplings induced by the magnetic field. We do a systematic search of parameter space by computing torsional mode frequencies for various values o...
