Utilization of Liquid Carbon Dioxide for Planetary Exploration
The major component of the atmosphere of Venus and Mars is carbon dioxide CO2. This proposal is to use this carbon dioxide for planetary exploration...

Carbon Formation Theory for Space Oxygen Processes
Production of oxygen from the Martian atmosphere or lunar soil and the recovery of oxygen in manned space environments may include carbon formation from CO as a unit process. Thermodynamic...

Active Control of Axial Forces in Beam String Space Frames
The present work discusses a formulation for active control of axial forces of strings in beam string structures to dynamically and/or statically reduce the responses, and proves both...

Stability Analysis of Optimal Active Control Systems with Time-Delay and Other Influence Parameters
This paper presents a theoretical solution for determining the stability region of multi-story buildings equipped with one active tendon controller on a certain floor. In this theoretical...

Robust Active Control of Cable-Stayed Bridge Subjected to Earthquake Ground Motion

Digital Signal Processing Techniques for Active Structural Control
In the past, implementation of active structural control strategies employing PC-based hardware has been problematic due to excessive computational times required for processing the measured...

Generalized Optimal Active Control with Embedded and Half-space Soil-Structure Interaction
The paper presents an optimal active control algorithm with soil-structure interaction for seismic response. By using an intelligent device in the feedback gain matrix, the algorithm can...

CDR - A Chemical Solution to a Mechanical Problem

Use of Expert Systems in Selecting Equilibrium Isotherms of Organic Compound Adsorption on Activated Carbon
An outline of an Expert System (ES) that aids in selecting adsorption isotherms is presented. Such an ES provides an efficient technique for screening the present literature. The ES helps...

Application of Numerical Models in the Design of Clarifiers
In this study, a numerical model of a circular clarifier was applied to reveal the effects of the water depth on the hydraulic and removal efficiency. The velocity and solids concentration...

Evaluating Activated Sludge Secondary Clarifier Performance: A Protocol
To establish a consistent methodology for evaluating secondary clarifier performance, the ASCE Clarifier Research Technical Committee prepared procedural guidelines in the form of a draft...

Sludge Hopper Design for Activated Sludge Clarifiers
Only in the past few years has any attention been allocated to the transport characteristics of sludge collectors. However, no attention has been given to a design rationale for the sludge...

Evaluation of Fe oxide-coated GAC for removal and recovery of Cu(II) from water
A composite solid, prepared by precipitating an Fe oxide onto granular activated carbon (GAC), was evaluated as an adsorbent for the removal and recovery of Cu(II) from water. Relative...

Effect of Sludge Blend on Dewatering Characteristics
This study compares the performance of high solids centrifuges when processing anaerobically digested and undigested mixture of primary sludge and waste activated sludge, in order to evaluate...
