This paper presents an architecture of a charger based on an LDO regulator with high efficiency for a Li-Ion battery which controlled the three-mode: trickle current, fast constant current and constant voltage modes. The simulation results provide the trickle current of 250mA, maximum charging current of 1.12A and charging voltage of 4.2V at the power supply of 4.8 -5 V using TSMC 180nm CMOS technology.

In the last years, Virtual Reality (VR) has been established itself as a highly promising media technology for reconstruction and presentation of cultural heritage sites to a wide audience. Virtual Reality enables not only an exploration of a single artefact but of many virtual objects spatially and temporally arranged into a single scene. The users enter an artificially created space and get a feeling of being a part of it. They can perceive and interact with the objects in the virtual environment in natural way. In this paper we propose a conceptual model of the VR module for the “Virtual Plaza for Immersive Representation of Bulgarian Cultural Heritage Sites”. It contains an analysis of the possible input data and the developed workflows to help experts from the cultural heritage domain to implement various scenarios for presentation of single artefacts and complete scene par of cultural heritage site using the benefits of Virtual Reality as visualization medium.

The models transformation is the fundamental key in Model Driven Architecture approach. In Model Driven Architecture there are two transformations kinds: the CIM to PIM transformation and the PIM to PSM transformation. The researchers focused on the transformation from PIM level to PSM level, because there are several points in common between these two levels. However, the transformation from CIM level to PIM level is rarely discussed in research subjects because they are two completely different levels. This paper proposes a model transformation method to master the transformation from CIM to PIM web-based in accordance with the Model Driven Architecture approach. Indeed, the main value of this method is to propose a transformation from business-oriented models to web-oriented models. This method is founded on building a good CIM level via well-defined rules, allowing us to win precious models that facilitate the task of the transformation from CIM to PIM web-based. Then, we define a set of well- selected rules to move from CIM to PIM web-based so as to ensure a semi-automatic transformation. This method conforms to MDA recommendations by considering the business dimension in the CIM level, and by modeling this latter level using UML activity diagram which is one of OMG standards for modeling business process. Nevertheless, we used UML models into the PIM level, because UML is recommended by MDA in this level.
Scientists have been trying to identify all of the genes in the human genome since the initial draft of the genome was published in 2001. Over the intervening years, much progress has been made in identifying protein-...
