OPTIMAL DESIGN OF ARCH DAMS FOR FREQUENCY LIMITATIONS USING CHARGED SYSTEM SEARCH AND PARTICLE SWARM OPTIMIZATION
In recent years, the importance of economical considerations in the field of dam engineering has motivated many researchers to propose new methods for minimizing the cost of dames and in particular arch dams. This paper presents a method for shape optimization of double curvature arch dams corresponding to minimum construction cost while satisfying different constraints such as natural frequenc...
متن کاملPhysical Aspects of Charged Particle Track Structure
A plasmon generated by a swift charged particle constitutes a coherent excitation about the particle track. We discuss the physics of the plasmon in conden~ed m.atter and its e~ects on ele~tr?n transport in liquid water. Criteria for the existence of the plasmon III a given substance, Its chara~teflsttcs when generated by a swift charged particle, its representation in impact parameter space, a...
متن کاملMotion of a Classical Charged Particle Physical
1550-7998=20 The Lorentz-Dirac equation is not an unavoidable consequence of solely linear and angular momenta conservation for a point charge. It also requires an additional assumption concerning the elementary character of the charge. We here use a less restrictive elementarity assumption for a spinless charge and derive a system of conservation equations that are not properly the equation of...
متن کاملRadiobiological Effects of Highly Charged Ions
The radiobiological effects of highly-charged-ion beams are of interest for tumortherapy and for radioprotection in space. In tumor therapy, high-energy protons and carbon ions exhibit an inverse dose profile, i.e. an increase of energy deposition with penetration depth. This allows a greater tumor dose for protons and carbon ions than for photons. In addition, for the heavier carbon ions, this...
متن کاملHeavy-ion tumor therapy: Physical and radiobiological benefits
High-energy beams of charged nuclear particles !protons and heavier ions" offer significant advantages for the treatment of deep-seated local tumors in comparison to conventional megavolt photon therapy. Their physical depth-dose distribution in tissue is characterized by a small entrance dose and a distinct maximum !Bragg peak" near the end of range with a sharp fall-off at the distal edge. Ta...
