An integral financial stability index is constructed using Israel macroeconomic data. Approaches relying on the use of dependent variable as well as principal component method and its modifications are examined. Obtained indexes are compared in terms of their forecast quality. In the case of no dependent variable the influence of structural shift is analyzed. © 2014 The Authors. Published by El...

OBJECTIVES This study aimed to compare the dimensional accuracy of two indexing materials, an acrylic resin (GC pattern resin) and a castable composite (Bredent). The effect of time lapse until investment was also investigated. MATERIALS AND METHODS Two standardized brass dies 15 mm apart were prepared and then 20 identical coping-bar assemblies were designed and fabricated by a rapid prototy...

We study skew product systems driven by a hyperbolic base map Ŝ : Θ → Θ (for example, a baker map or an Anosov surface diffeomorphism) and with simple concave fibre maps on R+ like x → ĝ(θ) arctan(x), where θ ∈ Θ is a parameter driven by the base map. The fibrewise attractor is the graph of an upper semicontinuous function θ → φ̂∞(θ) ∈ R+. For many choices of ĝ, φ̂∞ has a residual set of zeros, b...

the effect of different solvent systems on the extraction of antioxidant and anti radical agents of grape seed was studied. for this purpose 6 different solvent systems with similar polarity and different selectivity were used to prepare grape seed extract. extraction efficiency, reducing activity, radical scavenging property and the effect of each extract on the increase of thermal resistance ...

application of distributed generation (dg) units in distribution networks has increased in recent years. sizing and sitting of dg units are two important factors which should be considered, especially for reduction of power losses in distribution system. this paper presents a new approach for dg placement in distribution systems using the mixed integer nonlinear programming (minlp). this approa...

the effect of flour extraction rate on flour composition, dough rheological characteris-tics and the quality of iranian flat breads (lavash, taftoon and barbari) and their staling rate was investigated. flours with different extraction rates (70, 75, 80, 83, 86, 88, 90 and 93) were subjected to different tests. resultes indicated that, by increasing the extraction rate, the amount of protein, f...

The degradation of the overall stability corroded rolled H-shaped steel beams under bending conditions has not been extensively studied. In present study, monotonic tensile tests and were conducted on seven that subjected to electrochemical corrosion in order discuss influence material’s mechanical properties conditions. test results have indicated strength, elastic modulus, elongation declined...
