I propose to the administrator of this forum, to open a topic "technical discussions" in order to ensure an exchange between the specialist and ensure a climate scientist at the expense of hot daily download

he John Day Dam outside of Portland, Oregon is a huge producer of electricity and a key portal for goods on their way from the Pacific Northwest to Asia and beyond.
. But if the goods cant get through here, traffic on the entire Columbia River comes to a screeching halt. So with a gate on the dams lock broken, billions of dollars in commerce is on the line and weve got to do something about it. There are nine locks along the Columbia River, and watercraft cant make it through the dams without them. These water elevators can be operated with the touch of a button, providing a simple way for crafts to navigate the differing water levels on either side of a dam. But for eight months, the John Day has been getting by with a temporary fix a caisson that can be moved in and out of place to allow watercraft through. Its a labor intensive solution, one that takes three times as long as a working lock. Were about to change all that. The gate on the John Days lock is finally ready to go in, and were going to follow the process from start to finish

It is better if the subject " Software problems"
is divided based on softwares
for example
CSI products
Autodesk Products
CSC
I think it will be more useful
My final project about revisiting jackup rig using FE software Abaqus. I'm confuse to input material properties like increasing values. How to put elasticity and cohession values increasing with depth (i.e at 0-2m c=20kPa and at 2-8m c=20+2h)?

Vibration problems arise in the design of almost all engineering machinery and structures. Many of these problems are extremely complex but their solution is essential if a safe and satisfactory design is to be achieved. The equations of motion are often insoluble by the classical methods of the calculus and so it is necessary to approximate on order to reduce them to a set of linear equations. The use of matrices simplifies the solution of sets of linear equations. This book describes the matrix formulation of the equations of motion and techniques for the solution of matrix equations. The book describes some typical computer methods and also includes a large number of problems (with solutions) which may conveniently be solved by using a desk calculating machine.
