Analysis of the Band-Pass and Notch Filter with Dynamic Damping of Fractional Order Including Discrete Models

The paper presents analysis of the second order band-pass and notch filter with a dynamic damping factor βd of fractional order. Factor βd is given in the form of fractional differentiator of order a, i.e. βd=β/sa, where β and a are adjustable parameters. The aim of the paper is to exploit an extra degree of freedom of presented filters to achieve the desired filter specifications and obtain a desired response in the frequency and time domain. Shaping of the frequency response enables achieving a better phase response compared to the integer-order counterparts which is of great concern in many applications. For the implementation purpose, the paper presents a comparison of four discretization techniques: the Osutaloup’s Recursive Algorithm (ORA+Tustin), Continued Fractional Expansion (CFE+Tustin), Interpolation of Frequency Characteristic (IFC+Tustin) and recently proposed AutoRegressive with eXogenous input (ARX)-based direct discretization method

Efficient Placement of Electric Vehicles Charging Stations using Integer Linear Programming

This paper presents an efficient optimization approach for the placement of electric vehicles charging stations within the road network. The approach is based on the integer linear programming technique for solving optimization problems. In this paper, the optimization problem is formulated as complex combinatorial problem with goal to find minimum number of strategically selected locations for charging stations which will enable covering of the route between each two nodes of the road network. The necessary input data are the road network configuration with distances and adopted electric vehicle autonomy. The input data are used for creation of the graph representing the road infrastructure with nodes as potential locations for charging stations. The application of proposed approach is demonstrated on example road configuration with emphasis on its scalability, generality and processing cost

This year MECO project celebrates its anniversary. Five years for a conference is not a long period. But, it is difficult to survive even a few years in the period of conference flooding. It is only possible if one does not make any compromise with the quality

Some Electromechanical Systems and Analogies of Mem-systems Integer and Fractional Order

This paper will provide some an applications of memristors and mem-systems with a particular focus on electromechanical systems and analogies that holds great promise for advanced modeling and control of complex objects and processes. Also, we present the connection between fractional order differintegral operators and behavior of the mem-systems.

Instruction-set architecture exploration strategies for deeply clustered VLIW ASIPs

Instruction-set architecture exploration for clustered VLIW processors is a very complex problem. Most of the existing exploration methods are hand-crafted and time consuming. This paper presents and compares several methods for automating this exploration. We propose and discuss a two-phase method which can quickly explore many different architectures and experimentally demonstrate that this method is capable of automatically achieving a 50% improvement on the energy-delay product cost of an automatically generated architecture for an ECG detection application and a 1% energy-delay product cost improvement compared to a hand-crafted design

Analysis of Electrical Circuits Including Fractional Order Elements

This paper deals with the analysis of electrical circuits with classical one-port elements including two novel defined one-port fractional order elements: fractional-order resistive-capacitive RC-alpha and fractional-order inductive RL-alpha element. The definitions and analytical relations between current, voltage and power of introduced fractional elements are provided. An example of fractional element realization via ladder electrical circuit composed of classical resistors, capacitors and/or inductors is presented. Several examples are analyzed to illustrate he behavior of electrical circuit with fractional order elements for different values of fractional order alpha including differentiator/integrator circuits as well as complex circuits without accumulated energy
