Thermal Response in Antenna Under Laser Irradiation
This investigation focuses on the thermal response of two objects under medium-intensity continuous-wave (CW) laser irradiation: (1) a homogeneous slab and (2) a complex electronic component,...

Inelastic Response of Metal Matrix Composite Tubes
An analytical method which exactly satisfies the equations of the boundary value problem for the inelastic response of laminated metal matrix composite tubes on a point-wise basis is presented....

Optical Scatter From a Space Craft Mirror Due to Microscopic Impacts
This article addresses the issue of how micrometeoroid and man made debris in the space environment can adversely change the optical resolution of a mirror. The study used an algorithm...

Space Station Microgravity Analysis and Assessment
The space station will be a platform for microgravity research. For superior microgravity science, the experiment locations must experience very little acceleration in the quasi-steady...

Modeling of Interaction of Small Particulates in Earth Orbit
The hazards posed by small debris is an area of increasing concern for all space systems. Depending on the size and relative encounter velocity of small particulates, there are a variety...

Integrated Spacecraft Environments Model (ISEM)
Capabilities of the ISEM code are presented that can aid in the understanding of the complex interactions between a space system and the ambient environment. The development of ISEM has...

Efficient Path Planning Strategies for Unmanned Rover Vehicles
Path planning strategies are studied using an optimization model. Four main sub-models are discussed that contribute to the computing of minimum energy vehicle path planning. These are:...

Human Error Models for Structural Reliability
This paper presents models for human errors to be used along with reliability analyses. The models account for the occurrence of errors, their magnitude, and the detection of the errors....

Hurricane Windspeeds at Inland Locations
A critical review of the windfield and filling models used in the hurricane simulation procedure of Batts et al. [1980] clearly indicates that the hurricane windspeeds they obtained for...

Modelling of Extended Endplate Bolted Connections
A methodology based on finite element modelling is examined to study the behaviour of extended endplate bolted connections. ANSYS (Rev. 4.4), a large scale finite element program is used...

An Overview of Shotcrete Usage on the SSC
Shotcrete has been widely used on the Superconducting Super Collider for initial support of tunnel excavations in both the strong and weak rock formations encountered. Different types...

Effects of Sea Surface Movement on Offshore Structures
Examinations are made of the effects of the sea surface movement on the fundamental model response of deep-water, Wave-excited offshore structures. These effects are accounted for by using...

A Generalized Approach to the Local Stability of Stiffened Plates: Part I–Mathematical Formulation
The paper describes a generalized approach for the determination of the buckling stress of stiffened plates under combination of uniform biaxial compression, in-plane bending and shear...

Prisms and Antiprisms
Prisms form a group of mathematical figures, that have found widespread application in many disciplines, but especially in architecture and in building structures. They have two identical...
