Las estructuras institucionales y la agenda digital en México
- Montalvo Romero, Mª Teresa
onsidering that the
adoption of information and communication
technologies impacts the lives of citizens
improving access and efficiency in public
services and creating spaces of
transparency, it is only posible through an
agreement of State that establishes a
national agenda towards a knowledge
society. To this purpose, mexican Congress
has created the Special Commission for
Promoting Digital Access to Mexicans.
This commission along with the Mexican
Internet Association (Amipci A.C.) have
focused their attentio
n towards the making
of a law that permits the creation of a
national digital agenda. This will allow the
development of SIC structures and digital
government, to ease the inclusion of all
citizens in the net.
This work focuses its analysis in the
following elements, which...

Conception d'un filtre Analogique / Numérique
- Zhang, Xipeng
[ANGLÈS] In this thesis, a tunable analog filter with digital control is presented. The digital control is implemented by means of a Spartan 3A FPGA and programmable resistors. The system consists of two identical tunable filters. The master filter filters an input tone and the digital control compares the input and the output and modifies the programmable resistors to tune the central frequency of the filter to the input tone. Then, the same parameters are applied to the slave filter obtaining the tunable filter. Simulations and experimental results show the feasibility of this approach.

Communication: Predictive partial linearized path integral simulation of condensed phase electron transfer dynamics
- Huo, Pengfei; Miller, Thomas F., III; Coker, David F.
A partial linearized path integral approach is used to calculate the condensed phase electron transfer (ET) rate by directly evaluating the flux-flux/flux-side quantum time correlation functions. We demonstrate for a simple ET model that this approach can reliably capture the transition between non-adiabatic and adiabatic regimes as the electronic coupling is varied, while other commonly used semi-classical methods are less accurate over the broad range of electronic couplings considered. Further, we show that the approach reliably recovers the Marcus turnover as a function of thermodynamic driving force, giving highly accurate rates over four orders of magnitude from the normal to...
Minority carrier diffusion length in AlGaN: A combined electron beam induced current and transmission microscopy
- Cremades Rodríguez, Ana Isabel; Albrecht, M.; Voigt, A.; Krinke, J.; Dimitrov, R.; Ambacher, O.; Stutzmann, M.
Combined electron beam induced current and transmission electron microscopy measurements have been performed on both undoped and Si-doped AlGaN epitaxial films with aluminium contents x ranging from x=0 to x=0.79. TEM analysis shows the distribution and type of structural defects, the content of cubic phase and the decomposition phenomena strongly to depend on the Al content of the layers. The influence of the cubic phase on the electronic properties of the samples is discussed taking into account the high piezoelectric effect present in these alloys. The diffusion length of minority carriers has been determined by EBIC measurements and a lower...

The Development of Restricting Anorexia Nervosa: Does Personality Predict Individuals' Responses to Short-Term Fasting?
- Watkins, EL
Literature Review: Abstract Aims. There is concern that childhood weight-reduction programs may lead to eating disorder (ED) pathology. The aim was to provide a recent review of the impact of weight-reduction interventions on ED psychopathology or risks. Method. Reference lists and five electronic databases were searched to identify articles on overweight interventions for children aged five to 18, from 2008 to present. Papers were required to report on ED psychopathology. Results. The search yielded 267 articles on obesity interventions, of which 54 reported on psychosocial variables. Twenty-five articles, covering 24 studies, reported specifically on ED pathology or risks, and met...
Analysis and Optimization in Design of Randomized PWM Switching Patterns in DC/DC Converters
- H. Lev-ari; A. M. Stanković
Abstract — The paper addresses synthesis aspects of randomized modulation. While this switching technique attracted considerable interest of power electronic engineers over the last fifteen years, a large majority of references addresses the analysis aspect of randomization- given a randomization procedure the task is to quantify its effects on the power spectrum. This paper addresses the dual problem in which an objective function for the power spectrum is specified first, and then the task is to select the best randomization scheme from a given family. The synthesis problem is difficult because spectral formulas are nonlinear and quite involved. We concentrate...

- Sietse F. Boer; Æ Jaap; M. Koolhaas; D. Natarajan; H. De Vries; D. -j. Saaltink
Ó The Author(s) 2008. This article is published with open access at Springerlink.com Abstract The present study aims at delineating violence from aggression, using genetically selected high (SAL, TA, NC900) and low (LAL, TNA NC100) aggressive mouse strains. Unlike aggression, violence lacks intrinsic control, environmental constraints as well as functional endpoints. Conventional measures namely latency, frequency and duration were used initially to accomplish the objective of delineation using the above strains. However, these quantitative measures fail to reveal further details beyond the magnitude of differential aggression, especially within the high aggressive mouse strains. Hence, it was necessary to analyze further,...
Review Paper Medication-related Clinical Decision Support in Computerized Provider Order Entry Systems: A Review
- Gilad J. Kuperman
While medications can improve patients ’ health, the process of prescribing them is complex and error prone, and medication errors cause many preventable injuries. Computer provider order entry (CPOE) with clinical decision support (CDS), can improve patient safety and lower medication-related costs. To realize the medication-related benefits of CDS within CPOE, one must overcome significant challenges. Healthcare organizations implementing CPOE must understand what classes of CDS their CPOE systems can support, assure that clinical knowledge underlying their CDS systems is reasonable, and appropriately represent electronic patient data. These issues often influence to what extent an institution will succeed with its...

Textile electrode characterization: Dependencies in the skin-clothing-electrode interface
- Macías Macías, Raúl; Fernández Chimeno, Mireya; Bragós Bardia, Ramon
Given the advances in the technology known as smart textiles, the use of textile
electrodes is more and more common. However this kind of electrodes presents some differences regarding the standard ones as the Ag-AgCl electrodes. Therefore to characterize them as best as possible is required. In order to make the characterization reproducible and repetitive, a skin dummy made of agar-agar and a standardized measurement set-up is used in this article.
Thus, some dependencies in the skin-electrode interface are described. These dependencies are related to the surface of the textile electrode, the conductive material and the applied
pressure. Furthermore, the dependencies on clothing...
