Analysis of Spread Spectrum System Parameters for Design of Hidden Transmission
A. Luc
Radioengineering , 1995,
Abstract: A short analysis of spread spectrum communication system is performed with respect to the determination of its fundamental system parameters for transmitted signal hidden in the noise. The paper shows dependence of processing gains on the correlation circuits at the receiver side. The distance, from which the transmitter signal is hidden in noise, depends on the spread spectrum factor and the transmitted power. At a given interference power density and at a given requirement of transmitted signal hiding we can calculate the spreading factor of system. A processing gain of spread spectrum system determines a depth of signal hiding in the noise. A transmission range of spread spectrum communication system is given by the transmitted power and the processing gain of the system.
Social Time, Bodies and the “Logic of Waiting” in the Configuration of Urban Sensibilities  [PDF]
Ana Lucía Cervio, Victoria D’hers
Current Urban Studies (CUS) , 2014, DOI: 10.4236/cus.2014.21005

Considering the acceleration of social time encouraged by the ever increasing speed in the circulation of goods and products in the current phase of capitalist development, it becomes essential to reflect on the configuration of social sensibilities. Particularly, the logic is embodied in the way city dwellers are, in their feelings and in their modes of possessing (physical things/property). Based on observations from Argentine life that illustrate the unequal access to basic urban services and goods, this article assesses the concept of “waiting mechanism” and its articulation with social sensibilities in peripheral urban contexts. The main assumptions of this analysis are that “waiting” affects bodies and that the experience of the city results from the class inter-play of social and bodily distance and proximity, which opens certain paths and closes others. From this standpoint, it is demonstrated that this “logic of waiting” yields feelings of helplessness socially reproduced through the assertion that “things will always be this way” and structured from the repetition of the experience of lacking (lack of access to basic sanitation, lack of possibilities of transportation, and so on). Thus, the emergence of “waiting” as an ability becomes problematic since it is one of the mechanisms manifesting the living conditions of people (and their historically constructed sensibilities) from the outskirts of cities in the twenty-first century.

Publicaciones periódicas en Argentina: producción discursiva e institucionalización. Referencias a la psicología
Rossi,Lucía A.;
Anuario de investigaciones , 2007,
Abstract: journal's discursive production in argentina related to institutions, is considered from a contextual, prospective view. gender peculiarities and inner organization of conceptual and discursive proposals of journals are analyzed in order to enlight its different itineraries but also figure up the groups who build the journal since a scientific, but also political perspective. some journals present official institutional production, (university). others, a intermediate level- show the discursive production of professional associations, or organized groups. there is a third group of journals without institutional support: one of them a open tribune allows alternative discurse take place. other journal's editor comittee offers free, wide calls for debate. as journals regulate the process of building conceptual and discurse search for findings and agreements, provide the conditions for building institutions the effect of journals over institutions will be researched.
Redes discursivas, políticas e institucionales en las publicaciones periódicas en Argentina (1902-1962): Su influencia en la conformación del discurso psicológico
Rossi,Lucía A.;
Anuario de investigaciones , 2008,
Abstract: this paper deals with the configuration of the psychological discourse published in argentine journals (1900 - 1957) to specify their influence in the different ways of the psychological discourse, according to the scientist and political intention given by the group they belong. it starts with a presentation of them in a wide and political environment. then, it analyzes the articulation among the publications and the institutions that support them. the aim is to reconstruct the weft of the discursive and social alliances among authors -alternation, presence, absence. this will allow to conjecture about the possible intersections or borders among the publications and the appreciation from a discursive analysis methodological approach.

Manejo nutricional en esofagectom a complicada por quilotrax
Diaeta , 2009,
Abstract: perioperative nutrition in digestive tract surgery (esophagectomy) is a basic pillar as regards therapeutic measures, considering a high percentage of affected patients have preoperative malnutrition and since the correlation between inadequate preoperative intake and postoperative complications is widely known. chylothorax is an unusual complication; it has a considerable mortality rate due to nutritional, immunological and body fluids alterations. although the appropriate treatment is controversial, traditional principles in this treatment consist in reducing chyle flow, draining the pleural cavity, preventing sepsis complications and providing enteral nutrition with medium chain triglycerides (mct), which go directly to the portal system. total parenteral nutrition is the option when oral/enteral nutrition has failed. in this paper, a clinical case is introduced where a woman had esophagectomy which evolved into chylothorax at the postoperative stage, and the nutritional management applied is described.
Mujeres, trabajo y educación A principios del siglo XX: las maestras en la prensa católica del sudoeste bonaerense argentino
Diálogos Revista Electrónica de Historia , 2011,
Abstract: the figure of the teacher is significant for the catholics because it resumes many important problems for the catholic church in the end of the xix century and the first decades of the next: the laicism in public education, the remunerated work of women out of the house and the secondary education of women. in particular, the objective of this article is to identify the arguments the catholics used to evaluate the teaching profession. the sources used are the press publications that are printed in bahia blanca and are disseminated in a wide area of influence that covers the southwest of the provincia de buenos aires, the federal territory of la pampa and the north of patagonia, during the first three decades of the xx century. looking at the press discourse from a genre point of view, it will be shown that although there is a laicism process, the catholic formulations contribute in the profile construction of the teaching profession as a feminine mission with roots in the maternal nature. also, even when these ideas are not meant to subvert the genre relations, they support some mutations in the feminine condition because in some cases they legitimate the access to higher education, the work and the right to associate. in the first place, the particular situation of the teaching as a job for women in the southwest of provincia de buenos aires is reconstructed. in the second place, the point of view about the teaching profession transmitted by the catholic press is analyzed.
Construyendo ciudades inseguras: temor y violencia en Argentina
EURE (Santiago) , 2001, DOI: 10.4067/S0250-71612001008200001
Abstract: two processes characterized argentinean urban development during the 90s: increasing crime and fear of crime, and the development of gated communities. both processes have consolidated a model of urban development based on the redefinition of public spaces as well as the importance and development of private closed urbanization. thus, public security has been called as the main reason for people to justify a process of sociospatial segregation that has deeper roots that should be analyzed. in that sense, this article aims to open up a debate on the importance of violence and fear of crime in the definition of the cities own future
?Ciudad sin ciudadanos? Fragmentación, segregación y temor en Santiago
EURE (Santiago) , 2004, DOI: 10.4067/S0250-71612004009100006
Abstract: the city′s image as space of diversity and as a celebration of difference, is under threat in santiago. alternative and dominant images depict the city as conflictive, unruly, disorderly and insecure; where difference became a dangerous element that should be excluded or segregated. in this way, a "city without citizens" is being built, a "no-city" in which people does not interact, just move in the space. the main objetive of this article is to analyze this situation by focusing on one of its elements: fear of crime. the result presents many questions that need to be addressed about the city that is being built and the social consequences of this process.
Las presencias de los padres en las instituciones educativas y la configuración del trabajo docente: el caso de una escuela privada de la Ciudad de Buenos Aires
Intersecciones en antropolog?-a , 2008,
Abstract: this article is based on the hypothesis that the particular shape teacher work takes in a private school in buenos aires city is related to the presence of pupils' parents in the institution. under consideration are ideas about teacher work based on the anthropological relational school which recuperates the meanings produced by the different actors (teachers, pupils' parents) involved in the way specific problems are constructed. here the great diversity that can be found in families' ways of being present at school is fore fronted, as it is considered that a comprehensive analysis of actors should not avoid their mutual relations. this will allow the contents of power relations existing between teachers and families in relation to their positions as regards schooling processes to be specified.
