The present document is based on four lectures given for Master of Space and Application in University of Science and Technology of Hanoi. It consists of four parts. The first devoted to filters, the second to DC/DC converter, the third discusses the phase locked loop and the last the modulation. For convenience of the readers the work is organized...
The mechanistic involvement of the renin-angiotensin system (RAS) reaches beyond cardiovascular physiopathology. Recent knowledge pinpoints a pleiotropic role for this system, particularly in the lung, and mainly through locally regulated alternative molecules and secondary pathways. Angiotensin peptides play a role in cell proliferation, immunoinf...
In the framework of a national funded program for nuclear safety, a first prototype of portable gamma camera was built and tested. It integrates a Caliste-HD CdTe-hybrid detector designed for space X-ray astronomy coupled with a new system-on-chip based acquisition system (FPGA and ARM microprocessor) and thermo-electrical coolers for a use at room...
Rheolef is a programming environment for solvingpartial differential equations (PDE) by finite element methods (FEM).Rheolef is botha C++ libraryanda set of commands for unix shell programming.Rheolef expressions bases on the variational formulation of PDEs:polynomial spaces, fields and bilinear formsare C++ types for variables, that can be combin...
Since the mid-2000s, new co-design sites began to emerge all over the world. These "equipped environments" are extremely diverse in their forms: 3D conception virtual environments, Fab Labs, Living Labs, co-work spaces etc. Current available tools range from the simplest to the most sophisticated virtual environments through 3D printers. Despite th...
The present paper is an accessible digest, along with extensions, of previous work by the authors. We propose an unifying and versatile framework for a class of discrete time systems whose state is an element of a group, that we call linear observation systems on groups. Those systems strictly mimic linear systems in the sense that + is replaced wi...
