The goal of this article is to present interactive didactic software for analog to digital conversion using PCM method. After a short introduction regarding vocal signal processing we present some method for analog to digital conversion. The didactic software is an applet that can be direct accessed by any interested person.

BACKGROUND Vietnam is experiencing an epidemiologic transition with an increased prevalence of non-communicable diseases. Novel, large-scale, effective, and sustainable interventions to control hypertension in Vietnam are needed. We report the results of a cluster-randomized feasibility trial at 3 months follow-up conducted in Hung Yen province, Vietnam, designed to evaluate the feasibility and...

Systems Engineering (SE) provides a structured, systematic approach to business and technical risk reduction and hazard mitigation. The emphasis of the workshop is on the use of SE by the human factors engineer (HFE) and the role of the HFE in an SE process. The IEA2006 workshop consists of a 90-minute didactic session (summarized here) and a 2-hour practicum, which consists of the detailed ana...

In this paper a new model is proposed for Gate Oxide Short defects based on a non-split MOS transistor. Because the MOS is not split, this model allows to simulate minimum transistors in realistic digital circuits. The construction of the model is presented in details using a comprehensive and didactic approach. It is demonstrated that the electrical behavior of the proposed model perfectly mat...

In this paper authors present a didactic method for teaching Data Structures on Computer Science undergraduate course. An approach using functional along with procedural languages (Haskell and ANSI C) is presented, and adequacy of such a method is discussed. Authors are also concerned on how functional language can help students to learn fundamental concepts and acquire competence on data typin...

In order to improve the usability of the user interface of learning systems, a model is to be developed which supports the process of designing user interfaces with regard to the didactic basis which will be used. Secondly a user model will be constructed which integrates cultural differences among learners and forms the basis for the adaptation of the user interface. In order to achieve these ...

BACKGROUND With increasing pressure to use operating room time efficiently, opportunities for residents to learn fiberoptic orotracheal intubation in the operating room have declined. The purpose of this study was to determine whether fiberoptic orotracheal intubation skills learned outside the operating room on a simple model could be transferred into the clinical setting. METHODS First-year...
