Statistical models for surface-atmosphere energy balance components (net radiation, sensible heat, and soil-stored heat) as functions of global radiation are proposed. This study was carried out during three seasons (winter, spring, and summer) in Mexical... see more

Piezoelectric actuators are the potential actuators having a wide range of applications insmart structures and systems. However, the presence of hysteresis nonlinearity leads todegradation in their performance. This paper discusses a mathematical model fo... see more

The fundamental relationship between the concentration of suspended sediment, C, of a river and its water discharge, Q, during floods is studied qualitatively by analyzing temporal graphics and hysteresis curves (C-Q) graphics. The study of 20 floods of b... see more

The specific conductivity of aqueous cetyltrimethylammonium bro­mide solutions has been investigated below and above the critical micelle con­centration, in order to elucidate slow structural changes. Around the Krafft temperature (˜25 °C) the monomer sol... see more

O conceito de hysteresis sugere que um choque sobre a taxa de câmbio de um país desloca o equilíbrio do setor externo. Neste contexto, a experiência das flutuações do caso brasileiro a partir do Plano Real é exa-minada à luz dessa teoria, obtendo-se três ... see more

The traction electric drives for electric rolling stock of alternating current employ the diode and thyristor rectifiers that predetermine a series of shortcomings. These include the significant emission of reactive power and higher harmonics of currents ... see more

This paper examines the daily struggles of unionized employees whose municipal workplace was undergoing major change influenced by New Public Management. In-depth interviews with 45 front-line service providers revealed widespread frustration with working... see more

Reactive sputter processes frequently exhibit stability problems. The cause of this is that these processes normally exhibit hysteresis effects in the processing curves. Eliminating or decreasing the hysteresis would significantly simplify the use of reac... see more
