High tall buildings are more susceptible to dynamic excitations such as wind and seismic excitations. In this paper, design procedure and some current applications of tuned mass damper (TMD) were studied. TMD was proposed to study response of 20 storey height building to seismic excitations using time history analysis with and without the TMD. The study indicates that the response of structur...

Currently employed intrusion detection sensor configurations rarely change. This represents a broad, static attack detection domain. Changes within a dynamic environment, due either to policy changes, or changes within the system’s condition, can make certain attacks more important than others. Static scopes will either result in flooding administrators with relatively less important attack rep...

The evaluation of operations number for the system design has been done for general design strategy. More general methodology for the system and circuit design was elaborated by means of optimum control theory formulation. This approach generalizes the design process and generates infinite number of the different design strategies. The main equations for this general design methodology were ela...

Numerical algorithms for D-optimum design usually rely on a discretization of the design space into a finite set X. Their speed then depends on the cardinality of this set. We show in this paper how it is possible, during the search for an optimum design, to remove from X some design points that cannot be support points of the optimum design, and therefore to accelerate the algorithms.

We consider the problem of designing optimal linear codes (in terms of having the largest minimum distance) subject to a support constraint on the generator matrix. We show that the largest minimum distance can be achieved by a subcode of a Reed-Solomon code of small field size. As a by-product of this result, we settle the GM-MDS conjecture of Dau et. al. in the affirmative.

in this paper we propose and construct fuzzy algebraic additive model, for the estimation of risk in various fields of human activities or nature’s behavior. though the proposed model is useful in a wide range of scientific fields, it was designed for to torrential risk evaluation in the area of river evros. clearly the model’s performance improves when the number of parameters and the actual d...

this paper provides a fuzzy based decision support system (dss) for risk analysis in e-tourism ( electronic tourism ) investment. in general term, e-tourism is the use of information and communication technology (ict) in tourism which may allow operating tourism in least variable cost, least time and increased work efficiency. it is worth noting that there are many factors that affect the deve...

NASA has defined a metric to determine the necessary launch capacity for an advanced life-support system (ALS), designed to support humans for an extended duration beyond low earth orbit. This metric allows the comparison of techniques and technologies over time and between mission scenarios, yielding the optimum physical-chemical and bioregenerative array for human life support. The metric in ...
