We present software for spherical harmonic analysis (SHA) and spherical harmonic synthesis (SHS), which can be used for essentially arbitrary degrees and all co-latitudes in the interval (0◦, 180◦). The routines use extended-range floating-point arithmetic, in particular for the computation of the associated Legendre functions. The price to be paid is an increased computation time; for degree 3...

A metal-carbide-intermetallic material based on combustion products of the layer system (Ti-Al-Si)/(Ti-C)/Ti was for first time obtained with help self-propagating high-temperature synthesis (SHS) combined pressing. Exothermic from elementary powders carried out at a pressure 10 MPa, and pressing hot product 100 MPa. It has been shown that SHS contributes to formation permanent joints «metal/ca...

Biochemical research is increasingly using formal modeling, simulation, and analysis methods to improve the understanding of complex systems. Probabilistic analysis techniques such as Monte Carlo methods can be used to determine reachability or safety probabilities for large Stochastic Hybrid System (SHS) models, but systems containing influential rare events may require prohibitively large num...

a r t i c l e i n f o India is a country where 300 million people still live without access to formal electricity, and where hundreds of millions more live with irregular supply through the existing grid network. This paper examines business innovation in the diffusion of off-grid solar technologies in India. An in-country survey of off-grid solar energy providers from across the nation was con...

Spherical harmonic synthesis (SHS) of gravity field functionals at the Earth’s surface requires the use of heights. The present study investigates the gradient approach as an efficient yet accurate strategy to incorporate height information in SHS at densely-spaced multiple points. Taylor series expansions of commonly used functionals quasigeoid heights, gravity disturbances and vertical deflec...

Stable rotor levitation is a challenge for rotational gyroscopes (magnetically suspended gyroscopes (MSG) and electrostatically suspended gyroscopes (ESG)) with a ring- or disk-shaped rotor, which restricts further improvement of gyroscope performance. In addition, complicated pick-up circuits and feedback control electronics propose high requirement on fabrication technology. In the proposed g...

This paper is mainly addressing the design and analysis of a DC micro grid power system in a remote area in Bangladesh. Generation of electricity is not enough to serve its demand. Majority of the islands and the rustic communities are deprived from electricity and most of them are relying on some fossil fuels for searching their required energy. The cost of fuels is high and for this reason th...

the nucleus marks diminutive. Pingding infixation not only creates onset clusters but also introduces a phoneme. Both features are otherwise not found elsewhere in the language. We argue that the infix -, which is cognate with the diminutive -r suffix in other Mandarin dialects, is the result of rhotic metathesis (cf. Blevins and Garrett (1998)). This study shows that Pingding infixation presen...

NMR experiments of " B by both field-swept and high-resolution NMR are reported to probe the electric field gradient at boron sites and its distribution in Pyrex glass. Both spectra are successfully interpreted with the same set of parameters. It is stressed that field-swept NMR experiments to observe total powder spectrum can be helpful to get information on electric field gradients and asymme...

A passive attacker can compromise a generic anonymity protocol by applying the so called disclosure attack, i.e. a special traffic analysis attack. In this work we present a more efficient way to accomplish this goal, i.e. we need less observations by looking for unique minimal hitting sets. We call this the hitting set attack or just HS-attack. In general, solving the minimal hitting set probl...
