Rendements d’utilisation et consommation d’énergie au Québec

The concept of useful energy consumption has been used by some authors by weighting observed energy consumptions. It is argued in this paper that the weights should not be the regression parameter estimates of the GNP on various forms of energy consumptions as they are now, but they should be the mechanical use efficiency of each energy form. A number of functional forms of the GNP are then obtained, all very good from the econometric viewpoint. Finally, it is pointed out that the rate of substitution between different forms of energy does depend on the functional form of the GN

INNOVATION OF TRAINING METHODS TO MEET THE NEEDS OF UNIVERSITY STUDENTS UNDER "LEARNING CITIZEN" MODEL

After reflecting on the situation, the paper focuses on analyzing the innovation of higher education methods to meet learners' needs under the "learning citizen" model in the context of approaching the Fourth Industrial Revolution, with many opportunities and challenges. The paper identifies that higher education innovation to meet learners' needs under the "learning citizen" model is an effective way to take care of people's spiritual and material life, which is an important contribution to build a learning society.

THE WAR ON NATIONAL DEFENSE IN THE SOUTHWESTERN BORDER AREA (1975-1979) AND SOME ORIENTATION OF UNIVERSITY TEACHING IN VIETNAM

The war to protect the Fatherland in the southwest border area (1975-1979) is a historical process of great significance for the cause of the struggle and defense of the Socialist Fatherland. In Vietnam, the teaching on the war to protect the Fatherland in the southwestern border has not been focused on all training levels. From the perspective of history, the article clarifies the cause and nature of the war to protect the Fatherland in the southwestern border, thereby drawing some lessons for the national liberation cause and orient the teaching content of tertiary level in Vietnam.

EULER CHARACTERISTIC OF TANGO BUNDLES

We are interested in a vector bundle constructed by Tango (1976). The Tango bundle is an indecomposable vector bundle of rank n-1 on the complex projective space P^n. In particular, we show that the Euler characteristic of the Tango bundle on P^n is equal to 2n-1

A characterization of the algebraic degree in semidefinite programming

In this article, we show that the algebraic degree in semidefinite programming can be expressed in terms of the coefficient of a certain monomial in a doubly symmetric polynomial. This characterization of the algebraic degree allows us to use the theory of symmetric polynomials to obtain many interesting results of Nie, Ranestad and Sturmfels in a simpler way.Comment: 14 page

The role of orographic effects on occurrence of the heavy rainfall event over Central Vietnam in November 1999

In this study, the WRF model is used to investigate the role of Central Vietnam terrain on occurrence of the heavy rainfall event in November 1999 over Central Vietnam. Two model experiments with and without terrain were performed to examine the orographic blocking effects during the event. In the terrain experiment, the results from a three-day simulation show that the model reasonably well captures northeast monsoon circulation, tropical cyclones and the occurrence of heavy rainfall in Central Vietnam. The topography causes a high pressure anomaly intensifying northeast monsoon. When the terrain is removed, the three-day accumulated rainfall decreases approximately 75% in comparison with that in the terrain experiment. The terrain blocking and lifting effects in strong wind and moisture laden conditions combined with convergence circulation over open ocean are the main factors for occurrence of the heavy rainfall event
