The Amber El Amino area is located 75 kilometres southeast of Prince Rupert. Access to the area is by helicopter from Prince Rupert or Terrace (Figure 1). The El Amino showing (BC MINFILE 103H 071) is located on Sulphide Creek (Figure 2) which drains eastward into Hanna (El Amino) Creek. The Amber showing (BC MINFILE 103H 171) is located 700 metres north of the El Amino showing. Hanna Creek dra...

La introducción de técnicas de predicción basadas en modelos estadísticos en el campo de la Ingeniería de Software lleva ya varios años, especialmente en la estimación de errores residuales luego de una actividad de prueba de un sistema o de defectos totales, detectados y no detectados, durante una actividad de inspección. Estas técnicas son muy valiosas en aquellas áreas en las que la estimaci...

Let Z = {Z(t), t ≥ 0} be a semimartingale reflecting Brownian motion that lives in the three-dimensional non-negative orthant. A 2002 paper by El Kharroubi, Ben Tahar and Yaacoubi gave sufficient conditions for positive recurrence of Z. Recently Bramson, Dai and Harrison have shown that those conditions are also necessary for positive recurrence. In this paper we provide an alternative proof of...

The quality of housing construction in border colonias and the impact of this on the environment and on the health, safety, and quality of life of their inhabitants stems directly from the methods of construction of these dwellings, the materials used, and their design. These were investigated for two Tecate communities, El Rincon and El Descanso, which included colonia sett lements. Conditions...

In the current work, the authors present a symbolic algorithm for finding the inverse of any general nonsingular tridiagonal matrix. The algorithm is mainly based on the work presented in [Y. Huang, W.F. McColl, Analytic inversion of general tridiagonal matrices, J. Phys. A 30 (1997) 7919–7933] and [M.E.A. El-Mikkawy, A fast algorithm for evaluating nth order tridiagonal determinants, J. Comput...

The El Farol bar model, proposed to study the dynamics of competition of agents in a variety of contexts (W.) is studied. We characterize in detail the three regions of the phase diagram (efficient, better than random and inefficient) of the simplest version of the model (D. Challet and Y.-C. Zhang, Physica A, 246, 407 (1997)). The efficient region is shown to have a rich structure, which is in...

the purpose of this article is to identify the various mystical interpretations of horuf-e-moqatta’e (separated letters) in qur’an. ten mystical interpreters-the qur’an-al-azim, haghayegh-al-tafsir, lata’ef- al-esharat, kashf-al-asrar, ara’es-al-bayan, ta’vilat, rouh-al-bayan, manzum e safi, bayan-al-sa’adah- have been selected from several centuries and their explanations, after entries about ...

ABSTRACT In 1829 James Dunlop published the first southern double star catalogue of some 253 stars. The accuracy this has been determined by using Aladin to cross-match them with Gaia DR2 and estimate their positional (right ascension, declination, position angle, separation) magnitude accuracy. Seven per cent could not be identified 14 were single We found 13 stars (5 cent) currently listed in...
