In this paper we propose a new scheme for optical signal routing within Linear Lightwave Network (LLN) subnets. LLN is a recently proposed ber optic network which performs only linear operations on optical signals: power combining , splitting and possibly linear optical ampliication. LLN can be partitioned into several subnets where each subnet is a tree providing full broadcast among all stati...

Recently, applicational and technological studies have been performed by a group of scientists and industry, led by DLR, basing on experiences with ocean-colour sensor MOS-IRS. The result is a new low-cost mission concept with special emphasis on coastal-zone remote sensing, which will be able to fill an imported gap in Earth observation data, i.e. to detect the strongly needed data for a bette...

Vibration from equipment mounted on the telescope and in summit support buildings has been a source of performance degradation at existing astronomical observatories, particularly for adaptive optics performance. Rather than relying only on best practices to minimize vibration, we present here a vibration budget that specifies allowable force levels from each source of vibration in the observat...

Integrating the crowd into established systems such as traditional relational databases poses new challenges to the design of a query optimizer. Not only the latency has to be considered, but also monetary costs and the accuracy of results. To achieve a better quality of the final answer, more money is needed to reward the workers. This problem apparently asks for trade-off solutions dependent ...

Female insects have a limited energy budget to invest in reproduction. Clutch size and egg size are two traits typically involved in energy budget trade-offs, and an optimum clutch size is generally predicted. This trade-off, however, is influenced by many factors including the probability of egg parasitism. We studied this possibility in the pine processionary moth (Thaumetopoea pityocampa), w...

Selection of players for a cricket team within a finite budget is a complex task which can be viewed as a constrained multi-objective optimization and a multiple criteria decision making problem. In cricket team formation, batting strength and bowling strength of a team are the major factors affecting its performance and an optimum trade-off needs to be reached in the formation of a good and su...

In this paper we present a novel method for obtaining fast software implementation of the Elliptic Curve Digital Signature Algorithm in the finite field GF(p) with an arbitrary prime modulus p of arbitrary length. The most important feature of the method is that it avoids bit-level operations which are slow on microprocessors and performs word-level operations which are significantly faster. Th...
