Measurements of intense, localized parallel electric fields are reported in association with inertial Alfvén waves and accelerated electron fluxes in a space plasma. The parallel electric fields are localized to several hundreds of Debye lengths and carry potentials on the order of the energy of the accelerated electron fluxes. The structures are observed at sharp maxima or minima of the pertur...

In this paper we identify and present techniques for determining and constructing parallel evaluation structures for polynomials on Custom Computing Machines (CCMs). Since CCMs achieve high throughput rates by the eeective use of pipelining, our primary interest is of the construction of resource eecient structures for any given polynomial P(x). Speciically, we consider CCMs whose conngurable l...

Combinatorial Designs, also known as experimental designs, historically first were used in agriculture. With the advent of electronic computers together with the significant advancement of combinatorics, combinatorial structures have become an often used means in computer science. At present, massively parallel computers become more and more reliable so that they can be used as production syste...

The workspace of a parallel manipulator is usually smaller than the size of the robot itself. It is important to derive new structures that enjoy the advantages of parallel manipulators and also have a large workspace. In this paper we present two configurations of similar structures RRRS and RRSR with rotating links. The RRRS structure has a relatively large workspace—larger than the size of t...

Parallel preference structures are characterized by indifference surfaces that are identical in shape and scale, each being a translation of a basic surface along parallel income-consumption curves. The purpose of this paper is to discuss the properties of parallel structures and their potential usefulness in models of labor supply and commodity demand. Limited applications in production analys...

In this paper, we analyse alignment discrepancies for discourse structures in English-German parallel data – sentence pairs, in which discourse structures in target or source texts have no alignment in the corresponding parallel sentences. The discourse-related structures are designed in form of linguistic patterns based on the information delivered by automatic part-of-speech and dependency an...

The circular dichroism, CD, spectra of the telomere repeats of vertebrates, d(TTAGGG), indicate that parallel type quadruplex structures or disordered single-stranded structures are formed in low salt. Anti-parallel quadruplex structures are favored in the presence of high concentrations, 140 mM, of sodium. External loop, also known as propeller, parallel type structures are favored in the pres...

This paper presents structural evidence of extensional activity in Central Alborz during Mesozoic. The structural evidence of homogenous early stage stretching such as layer-parallel to oblique boudinage of Permian and Triassic rocks in various portions of the study area accompanied by extensional-fibrous fractures were followed with more advanced extensional features. These extensional structu...

In this research, optimal design and assessment of multiple tuned mass dampers (MTMDs) capability in mitigating the damage of nonlinear steel structures subjected to earthquake excitation has been studied. Optimal parameters of TMDs on nonlinear multi-degree-of-freedom (MDOF) structures have been determined based on minimizing the maximum relative displacement (drift) of structure where for sol...

The tremor injury is one of the common symptoms of Parkinson's disease. The patients suffering from Parkinson's disease have difficulty in controlling their movements owing to tremor. The intensity of the disease can be determined through specifying the range of intensity values of involuntary tremor in Parkinson patients. The level of disease in patients is determined through an empirical rang...
