Abstract: Quickly identifying and apprehending the perpetrator of a violent crime – murder, robbery, rape, and abduction – represent major goals of all law enforcement agencies. The police aim at identifying the author as quickly as possible by using the data gathered upon investigating the crime scene, in order to prevent further violence. The activities to be performed for determining the precise means of committing the crime and for interpreting the criminal’s behavior in his/her interaction with the victim are highly complex and decisively important in establishing the perpetrator’s guilt.

Abstract: The research was achieved by applying several questionnaires and evaluation tests that have shown the efficacy of using the computer in building active thought and skills in the graphical representation of functions \"\", within a Cartesian reference system xOy. Our research was based on the following hypothesis: if we systematically use, in lessons of algebra and mathematical analysis, the GeoGebra software for drawing the graph of a function, then we shall contribute to building attitudes and competences in using the computer for the graphical representation of functions \"\" , within a Cartesian reference system xOy. The purpose of our study is to present a practical computer use model for the students from the Pre- and In-Service Teacher Training Department, “Vasile Alecsandri” University of Bacau, during their pedagogical practice stage of continuous training, aimed at building practical skills in supporting the teaching-learning process with computers. To deal with these issues, we are trying to find the best teaching-learning strategies by using the calculus technique. The research was conducted at the “Stefan cel Mare” National Pedagogical College from Bacau, by assisting 20 lessons of mathematics and 20 lessons of Information and Communication Technology, involving a group of 104 students in the 11th grade. In order to verify the hypothesis, we have established several objectives that orient and guide our activity: knowing the initial level of mathematical training in terms of graphical representation of functions; identifying the frame and reference objectives of the curriculum for mathematical education regarding the graphical representation of functions; designing and conducting a teaching process focused on the use of the computer and the GeoGebra software in learning the graphical representation of functions; final evaluation of the students’ level of training regarding the graphical representation of functions in a plane.

Abstract: Holding responsible a person for criminal liability is necessary if he commits an act that combines, both objective and subjective aspects, the required elements of a specific incrimination rule. The transformation of simple apparent crime takes place among others, also in the existence assumption of some facts which, although it accomplishes all the objective and subjective conditions imposed in the incrimination rule, in reality there are no illicit facts, but facts permitted by the law; in such cases it will not exist offense and by consequence it will be excluded both criminal liability and punishment (example gratia: justificative causes). This category of justificatory cases, fit to transform the apparent crime expressed in removing the criminal nature of the committed act, belongs to both legitimate defense and error of fact, which are stipulated in the Criminal Code, article 44 and article 51.In our approach, however, we do not intend to deal with those two institutions of criminal law - self-defense or error of fact - but we try to express a point of view on the existence and the effects that the legitimate putative defense produces – the state resulting from the contest of the two - the institution of criminal law, less dealt with in the doctrine for the judicial practice, although we believe that it is a reality that can not be challenged.

Relative adjoint transcendental classes and Albanese maps of compact Kaehler manifolds with nef Ricci curvature
Mihai Paun
Mathematics , 2012,
Abstract: Given a surjective holomorphic map between two compact Kaehler manifolds, we investigate the positivity properties of relative adjoint transcendental classes which are inherited from similar fiberwise properties. As a consequence, we solve a problem proposed by J.-P. Demailly, T. Peternell and M. Schneider concerning the Albanese morphism of Kaehler manifolds with nef anticanonical class.
Relative critical exponents, non-vanishing and metrics with minimal singularities
Mihai Paun
Mathematics , 2008,
Abstract: In this article we prove a non-vanishing statement, as well as several properties of metrics with minimal singularities of adjoint bundles. Our arguments involve many ideas from Y.-T. Siu's analytic proof of the finite generation of the canonical ring. An important technical tool is the notion of relative critical exponent of two closed positive currents with respect to a measure.
On the Hopcroft's minimization algorithm
Andrei Paun
Computer Science , 2007,
Abstract: We show that the absolute worst case time complexity for Hopcroft's minimization algorithm applied to unary languages is reached only for de Bruijn words. A previous paper by Berstel and Carton gave the example of de Bruijn words as a language that requires O(n log n) steps by carefully choosing the splitting sets and processing these sets in a FIFO mode. We refine the previous result by showing that the Berstel/Carton example is actually the absolute worst case time complexity in the case of unary languages. We also show that a LIFO implementation will not achieve the same worst time complexity for the case of unary languages. Lastly, we show that the same result is valid also for the cover automata and a modification of the Hopcroft's algorithm, modification used in minimization of cover automata.
L’ amèlioration de la competitvité des entreprises par une strategie de la qualité
Scientific Annals of the Alexandru Ioan Cuza University of Iasi : Economic Sciences Series , 2006,
Abstract: La concurrence accrue manifestée dans le marché détermine les entreprises de chercher des solutions pour améliorer leur compétitivité. Une solution viable est d’adopter une stratégie de la qualité, qui permet de former une perception favorable pour ses produits a ses clients. L’objectif du cet article este de mettre en évidence les avantages qu’on peut bénéficier les entreprises qui adoptent une telle stratégie fondée sur la qualité. Sont présentés les concepts intégrateurs de la qualité: Total Quality Control, Company Wide Quality Control, Total Quality Management, et leur importance pour le succès d’un démarche stratégique de la compétitivité.
