the sirri jacket offshore platform was designed and installed in persian gulf of iran in 1975 and has been in service since that time. the importance of offshore structure's stability and the failure of this kind of structure during an earthquake in different active zones revealed that earthquake loading has to be considered. in this paper, magnetorheological (mr) fluid dampers have been propos...

International Symposium on Wireless Personal Multimedia Communication (WPMC 2011) in Brest, France. Abstract: Current shipboard monitoring systems use extensive lengths of cables to connect sensors to control units. Replacing wired connections by wireless ones may be an efficient solution to reduce the ship weight and cost. Ships are characterized by a specific metallic environment which can se...

This dissertation presents two contributions to the development of autonomous aerial delivery systems (ADSs), both of which advance the prospect of enabling an ADS to land on a moving platform, such as the deck of a ship at sea. The first contribution addresses the problem of estimating the target’s position and velocity. A novel, dual-rate estimation algorithm based on Unscented Kalman filteri...

1. INTRODUCTION Since the eighties constant augmentation of the demand on worldwide maritime transportation together with acute economical competition have increased the pressure on ship owners and commercial fleets. Crews are often reduced to a minimum and sometimes to even one officer of the watch in the deck. In order to counterbalance these negative effects on safety navigation, and to faci...

The preferred method of randomizing a deck of N cards is the riffle shuffle–cut the deck into two stacks, then riffle the two stacks together. A number of mathematical models have been proposed for this process. The model which has received the most attention, and about which the most is known, is the GSR (for Gilbert, Shannon, and Reeds) shuffle. In this model, all permutations with exactly on...

Concrete bridge decks are prone to ice accumulation. The use of road salts and chemicals for deicing is cost effective but causes damage to concrete and corrosion of reinforcing steel in concrete bridge decks. This problem is a major concern to transportation officials and public works due to rapid degradation of existing concrete pavements and bridge decks. The use of insulation materials for ...

The instructions for generating and sustaining all life forms are encoded within each life form’s genome. A major challenge in the postgenomic sequencing era has been assigning functions to the hundreds of thousands of noncoding sequence elements within our nuclear genome that are homologous to sequences in other species. These snippets of DNA have been hypothesized to impart information for in...
