New building materials and products in construction reconstruction, which improve the performance efficiency characteristics of buildings, reduce material consumption, cost labor intensity, are always relevant. A promising direction for further development composite is employment pre-bound aggregate materials. Their production a two-stage process, involves at first creating an optimal mix gluin...

ty(x,y) denotes the number of positive integers < i and free of prime factors > y. In the range y > exp((loglogx)5T3+£), *9(x, y) can be well approximated by a "smooth" function, but for y < (logx)2-e, this is no longer the case, since then the influence of irregularities in the distribution of primes becomes apparent. We show that *¡>(x,y) behaves "locally" more regular by giving a sharp estim...

In this paper we propose a method to improve thewaveguides for optical communications based on 2-dimen-sional photonic crystals. To this purpose a standard channelwaveguide is sandwiched between two omnidirectionalChigrin-type 1D dielectric layer stacks. The combination oftotal internal reflection and photonic band gap reflectionenables improved confinement of optical si...

Israel Cidon received the B.Sc (summa cum laude) and the D.Sc. degrees from the Technion -Israel Institute of Techno logy, Haifa, Israel, in 1980 and 1984, respectively, both in electrical engineering. From 1977 to 1980 he was a consulting Research and Development Engineer involved in the design of rnicroprocessor-based equipment. From 1980 to 1984 he was a Teaching Assistant and a Teaching Ins...

Bio logy has been an important source of inspiration in building adaptive autonomous robotic systems. Due to the inherent complexity of these models, most biologicallyinspired robotic systems tend to be ethological without linkage to underlying neural circuit ry. Yet, neural mechanisms are crucial in modeling adaptation and learning. The work presented in this paper describes a schema and neura...
