The sliding mode control of Variable Structure Systems has a unique role in control theories. First, the exact mathematical treatment represents numerous interesting challenges for the mathematicians. Secondly, in many cases it can be relatively easy to apply without a deeper understanding of its strong mathematical background and is therefore widely used in the field of power electronics. This...

This paper presents a computer simulation model of the unity power factor uninterruptible supply (UPS) topology using single-phase matrix converter (SPMC) that focuses on switching integration for both rectifier and inverter operations. The proposed integrated switches capable controlling SPMC to operate as operation charge DC battery during normal switch an outage conditions continuously insta...

In the high power converters such as three-phase inverters is recommended to operate at low frequencies, due to the switching losses. In addition, modeling errors and non linear loads with unmodeled dynamics frequently degrade the controllers performance resulting in a poor transient response and instability. This paper presents a robust model reference adaptive controller (RMRAC) for three-pha...

This paper deals with the concept of a semi-public good. These semi-public goods are characterized by the fact that their use is being supplemented by specific private goods. The consumption of this complementary private good is constrained by an individual quantity constraint for each individual agent. The quantity constraints depend on the level of the semi-public good. For instance, car driv...

This paper presents empirical evidence about the relationship between market openness and markup distribution of manufacturing firms. The empirical analysis uses a panel data set of Spanish firms in the period 1990-2005, with a structural approach that lets us to identify individual mark-ups. The results point out that tougher competition associated to openness reduces the average of marginal c...

Since 2005, the Land Surface Analysis Satellite Application Facility (LSA SAF) operationally retrieves Land Surface Temperature (LST) for the Spinning Enhanced Visible and Infrared Imager (SEVIRI) on board Meteosat Second Generation (MSG). The high temporal resolution of the Meteosat satellites and their long term availability since 1977 make their data highly valuable for climate studies. In o...

The car industry is confronted with fundamental changes in society, technology and economy and forced to rethink its concept of mobility. Through constant strategic foresight, trend management and a holistic mobility vision, car manufacturers must develop innovative strategies that reflect current and future trends, in order to meet customer needs, technological standards and economic imperativ...
