Let G be a word-hyperbolic group with given finite generating set, for which various standard structures and constants have been pre-computed. A (non-practical) algorithm is described that, given as input two lists A and B, each composed of m words in the generators and their inverses, determines whether or not the lists are conjugate in G, and returns a conjugating element should one exist. Th...

Sticks at one of different orientation are placed in an i.i.d. fashion at points of a Poisson point process of intensity λ. Sticks of the same direction have the same length, while sticks in different directions may have different lengths. We study the geometry of finite cluster as λ → ∞. The asymptotic shape of the custer being determined by the probabilities of the sticks in various direction...

In recent years, many studies have been done on forecasting fuzzy time series. First-order fuzzy time series forecasting methods with first-order lagged variables and high-order fuzzy time series forecasting methods with consecutive lagged variables constitute the considerable part of these studies. However, these methods are not effective in forecasting fuzzy time series which contain seasonal...

Flexural wave propagation in an Euler–Bernoulli beam coupled to a set of spring–mass resonators is investigated in the presence of a pump wave in the form of a space–time modulation of the beamresonators coupling stiffness. A phase matching condition implies then that waves incident along or against the pump wave behave differently and gives rise in select frequency bands to one-way blocking an...

the objectives of this experiment were to investigate the application of new ligands including different atoms & evaluation their nucleophile effects against various metals. chemistry researchers are really interested in this field. from among various ligands, there are some ligands with different coordinating ligands as well. there are great number of intermediate complexes and major eleme...

The paper introduces the concept of fault diagnosis using an observer bank of autoregressive time series models. The concept was applied experimentally to diagnose a number of induced faults in a rolling element bearing using the measured time series vibration signal. Three distinct techniques of autoregressive modeling were compared for their performance and reliability under conditions of var...

Hashing has recently sparked a great revolution in cross-modal retrieval because of its low storage cost and high query speed. Recent hashing methods often learn unified or equal-length hash codes to represent the multi-modal data make them intuitively comparable. However, such representations could inherently sacrifice their representation scalability from different modalities may not have one...
