Characterization of hydraulic behavior of orifices in conduits

Nicolas Jean François Pascal Ghislain Adam

High-head power plants are the main pillar of Swiss peak electricity production. With the 2050 Energy Strategy approved by Swiss voters, the annual production of hydroelectricity should increase by 4%, while 90% of the technically feasible potential is alr ...

An Inner-Product Calculus for Periodic Functions and Curves

Michaël Unser, Daniel Andreas Schmitter, Anaïs Laure Marie-Thérèse Badoual

Our motivation is the design of efficient algorithms to process closed curves represented by basis functions or wavelets. To that end, we introduce an inner-product calculus to evaluate correlations and

Validating formulas for the prediction of ascent speed and mass transfer coefficient for liquid oil droplets and gas bubbles under pressure

Jeremy Samuel Arey, Jonas Gros

Several different formulas exist to predict the ascent speed of gas bubbles and oil droplets released in deep waters. Similarly, different formulas are also available to predict the mass transfer coefficient of compounds dissolving into water during ascent ...

Influence of geometry shape factor on trapping and flushing efficiencies

Anton Schleiss, Sameh Ahmad Kantoush

The trap efficiency of a shallow reservoir depends on the characteristics of the inflowing sediments and the retention time of the water in the reservoir, which in turn are controlled by the reservoir geometry. With the purpose of controlling the trapped a ...

Punching shear design in MC2010: incorporating new knowledge and grounding design expressions on physical models

Aurelio Muttoni, Miguel Fernández Ruiz

Model Code 2010 (MC2010) has presented a deep review on punching shear design with respect to previous versions of Model Code (1978, 1990). These changes have been motivated by the fact that MC2010 is grounded on a physical theory rather than on empirical ...

Ag-44(SR)(30)(4-): a silver-thiolate superatom complex

Francesco Stellacci, Kellen Michael Harkness

Intensely and broadly absorbing nanoparticles (IBANs) of silver protected by arylthiolates were recently synthesized and showed unique optical properties, yet question of their dispersity and their molecular formulas remained. Here IBANs are identified as ...

Influence of geometric, strain and size effects on bond in structural concrete

Aurelio Muttoni, Miguel Fernández Ruiz

Design formulations for calculation of bond strength in structural concrete members usually include a number of parameters such as the stress acting in the reinforcement, the concrete cover and the diameter of the reinforcing bars. These parameters are act ...

La teoría de la fisura crítica como base teórica para el diseño de losas frente a punzonamiento en el nuevo Código Modelo 2010 (The Critical Shear Crack Theory as a physical model for punching shear design and its implementation into new Model Code 2010)

Aurelio Muttoni, Miguel Fernández Ruiz, Juan Sagaseta Albajar

On April 2010, the first complete draft of new Model Code 2010 was published. It introduced a number of innovative design approaches, some of them with respect to shear and punching shear. Contrary to Model Code 90 (or some national and international codes ...

An application of Evolutionary Optimization Algorithms for Determining Concentration and Velocity Profiles in Sheet flows and Overlying Layers

David Andrew Barry, Roham Bakhtyar

The Particle Swarm Optimization (PSO) method and the Genetic Algorithm (GA) were used to derive formulas for determining the velocity and concentration profiles in sheet flows. Specifically, these evolutionary optimization algorithms were used in conjuncti ...

New provisions for punching shear in Model Code 2010 based on the Critical Shear Crack Theory

Aurelio Muttoni, Miguel Fernández Ruiz, Juan Sagaseta Albajar, Luca Tassinari

The provisions for punching shear around concentrated loads in the new Model Code 2010 (MC2010) have been updated, covering a large number of design cases such as slabs with and without transverse reinforcement, different column/slab geometries and prestre ...
