Evaluation of sunflower collection by genetic variability based on germination and plantlet development parameters using Artificial Neural Networks

The aim of the research work was to study the genetic variability of sunflower (Heliantus annuus L.) seeds collection. From 1500 available genotypes a set of 120 recombinant inbred lines coming from different countries were selected to perform the study. The genetic variability consisted in two types of experiments: in vivo and in vitro cultures. The recombinant inbred lines were classified usi...

– 5949 Annals of the University of Petro Ş Ani ∼ Economics ∼ Vol . Vii Universitas Publishing House Petro Ş Ani – Romania 2007

The paper approaches certain aspects regarding the involvement of the banking and industrial capital in the development and modernization of gold mining during the existence of „Mica” Company (1920-1948). The paper presents the political and economic factors contributing to the positive results in the field. It also provides examples of the way in which the banking and industrial capital was in...

Authors’ Reply to the “Comments on the Core Vector Machines: Fast SVM Training on Very Large Data Sets”

In this reply, we report results on using the Windows binary of the CVM on the checkers and other real-world data sets. Experimental results show that the CVM is much more stable than is reported in (Loosli and Canu, 2007). Moreover, the analysis of CVM’s stopping criterion in (Loosli and Canu, 2007) is based on some connections between the traditional ν-SVM and C-SVM using the 1-norm error. Ho...

Relativistic dynamics without conservation laws

We show that relativistic dynamics can be approached without using conservation laws (conservation of momentum, of energy and of the centre of mass). Our approach avoids collisions that are not easy to teach without mnemonic aids. The derivations are based on the principle of relativity and on its direct consequence, the addition law of relativistic velocities.
