QS University Rankings: Latin America - Brazilian dominance points to future economic might

Universities throughout Latin America are in a period of transition. Though precise circumstances vary by country, factors such as the growth in scientific research, massification of social demand for higher education, increased student mobility and the rise of private universities have exerted an influence across the region. These rankings aim to more closely reflect these circumstances than is possible in the overall QS World University Rankings®, as well as giving greater exposure to up-and-coming Latin American institutions. The new QS methodology employs criteria that address region-specific issues, such as the proportion of faculty with a PhD, research productivity per capita and web presence. We have also drawn on by far the largest surveys of Latin American academics and employers ever conducted. From an international perspective, a look at the top 200 provides further evidence of the emergence of Brazil as a future economic power alongside fellow BRIC nations Russia, India and China. Universidade de São Paulo (USP) tops the table, with Universidade Estadual de Campinas (Unicamp) and Universidade Federal de Minas Gerais joining it in the top ten. There are an impressive eight Brazilian universities in the top 20, and 31 in the top 100. Higher education has been earmarked as the engine-room to help Brazil fulfil its massive potential for economic growth, with enrolment tripling from two to six million in the last decade. However, the rankings also show the extent to which Brazil has prioritized research. A remarkable eight of the top ten for papers per faculty are Brazilian, alongside nine of the top ten for the proportion of academic with a PhD.

Recent OECD figures show that education investment grew more in Brazil than in any other OECD nation from 2000-2008 (as a proportion of GDP). The same report shows that Brazilian graduates have comfortably the highest career earnings premium of any OECD nation, which suggests that a more educated workforce is already beginning to reap dividends for the economy as a whole.
Alongside Brazil, universities from Chile, Mexico, Colombia and Argentina feature in a diverse top ten. A poll of Latin American academics named UNAM the region’s top institution for academic reputation, while Universidad de Buenos Aires was named by employers as the top producer of graduate talent. However, USP’s overall strength saw it top the table, ranking as one of the top four institutions in all but one of the seven indicators.
Mexico is the second best-represented nation, with 35 universities in the top 200, led by UNAM (5) and Tecnológico de Monterrey (ITESM) (7). The leading Mexican universities are highly regarded by both academics and employers throughout the region. UNAM ranked number one in the academic reputation survey, while ITESM was the second best-placed university in the employer reputation survey. However, Mexican universities generally perform less well in the research measures. Just two Mexican universities make the top 50 for papers per faculty, with similar scores recorded for citations per paper.
A total of 13 nations are represented in the top 200: Brazil (65), Mexico (35), Argentina (25), Chile (25), Colombia (21), Peru (6), Venezuela (5), Uruguay (4), Costa Rica (3), Cuba (3), Ecuador (3), Panama (1), Paraguay (1), and Puerto Rico (1).

ABSTRACT*

 

The economical and environmental impacts of fossil fuels have forced society to  investigate sustainable solutions.  The  interest  has

            focused on the renewable energy sources since the green and clean benefits. Consequently, investments in research and development in the field of power electronics have increased proportionally, especially in high voltage and high power grid-connected systems.

 

The distributed power generation (DG) systems are becoming more common as the need  for electric power increases because of taking advantage of using different energy sources such as wind and solar. A few examples are hybrid cars, solar houses or hospitals in remote  areas  where  providing  clean,  efficient  and  reliable  electric power is critical to the loads. In such systems, the power is distributed from the source side to the load side via power electronic converters in the system. At low and medium power applications, the task is often left to single-phase inverters where they are the only interface between sources connected to dc bus and loads connected to an ac bus. This dissertation investigates the power quality improvements to properly regulate  the  power  flow  between renewable  source  and  the  utility network. The control method for single-phase inverters used in low and medium power DG systems is based on (and also takes the advantage of) the well-known d-q transformation (which is mostly employed for three-phase   converters’   analysis   and   control   design).   The transformation requires at least two independent phases for each state variable in the system; thus a second phase must  be created. This virtual-phase can be done by DSP implementation, hence there is no need for additional hardware in the system, making it more attractive and cost effective method. 

 

The Proportional-Resonant (PR) controller based current control scheme,   compared   with   conventional  Proportional-Integral (PI)

            controller, not only provides a superior transient  response but  also provides a zero steady-state error as well as a high disturbance rejection and a low output current THD under grid-tie mode operation. The entire controller can be implemented in a DSP digital control board

    This  thesis  aims  to  present  the  design  and  practice  of  a  digital electronic ballast for fluorescent lamps. It introduces the characteristics of lamp, DC/DC converter, power factor correction circuit IC  6561, and resonant circuit IC 6574, The electronic ballast is developed by using IC 6561and IC  6574, and other circuits to meet the need for high power factor, long lamp life, high luminous efficiency, and dimming control.
    Also the circuit operation principle, analysis of carefully designed circuit parameters, practical consideration of self-excitation, and dimming control are explained in detail .The test of real design is carried out at last, and the result shows the proposed digital electronic ballast can fulfill the design purposes.
