This work introduces the concept of physical-digital objects: physical objects which allow people to interact with digital information as though it were tangible. I treat the design of physical-digital objects as a new field, and establish a conceptual framework within which to approach this design task. My design strategy treats objects as having both a physical and a digital identity, related...

a fundamental aspect of signal processing is filtering. Filtering involves the manipulation of the spectrum of a signal by passing or blocking certain portions of the spectrum, depending on the frequency of those portions. In this paper, Digital filters are designed using frequency specifications. Matlab provides different options for digital filter design, which includes function, calls to fil...

The transition to digital manufacturing has become more important as the quantity and quality of use computer systems in companies increased. It necessary model, simulate analyse all machines, tools, raw materials optimise process. is even better determine best possible solution at stage defining process by using technologies that data from simulations calculate an optimal design before it buil...

The maximum power point tracking (MPPT) control in the Photovoltaic system is the key control technology, however present controller has the disadvantages of long development cycle, high cost and complex verification, and there are some disadvantages carrying out totally physical simulation or totally digital simulation of different control algorithms. This paper carried out design of hardware ...
