Repeated patterns are useful clues to learn previously unknown events in an unsupervised way. This paper presents a novel method that detects relatively long variable-length unknown repeated patterns in a motion sequence efficiently. The major contribution of the paper is two-fold: (1) Partly Locality Sensitive Hashing (PLSH) [1] is employed to find repeated patterns efficiently and (2) the problem of finding consecutive time frames that have a large number of repeated patterns is formulated as a combinatorial optimization problem which is solved via Dynamic programming (DP) in polynomial time O(N 1+1/α ) thanks to PLSH where N is the total amount of data. The proposed method was evaluated by detecting repeated interactions between objects in everyday manipulation tasks and outperformed previous methods in terms of accuracy or computational time.

The paper presents new realization of grounded and floating capacitance multiplier circuits using tunable four-terminal floating nullors (TFTFNs). The resulting capacitance value is electronically tunable by means of two bias currents. The grounded capacitance multiplier uses one TFTFN and one grounded capacitor and the floating capacitance multipliers use two TFTFNs and one capacitor. The parasitic impedance effects on the proposed circuit are investigated. PSPICE simulation results are included which verify the workability of the proposed circuits.

Mapping of renewable energy sources has been done. It inspires to figuring out an escalation of energy demand at rural and remote area by promoting Energy Diversification programs.(EDP). Biomass, solar, wind and hydro are four renewable energy resources enable people to provide energy by their own. The mapping describes three zones based on the dominant of the resources. Upstream of tributary zone at which the hydropower may supply energy for running micro hydro power plant. Agriculture and plantation zone produces plenty of biomass for steam turbine power plant. Estuary and coast line zone is the open area where solar radiation and wind speed are potentially able to be harnessed for producing electricity. Promoting energy diversification based on mapping data followed by implementing appropriate technology may give much benefit for sustainable development. A small scale hybrid model power plant is introduced.

This article presents a voltage-mode universal biquadratic filter (low-pass, high-pass, band-pass functions), based on current controlled current conveyor transconductance amplifiers (CCCCTAs). The features of the circuit are that: the quality factor and pole frequency can be tuned orthogonally via the input bias currents: the circuit description is very simple, consisting of merely 3 CCCCTAs and 2 grounded capacitors. Without any external resistors, requiring no component matching conditions, and using only grounded elements, the proposed circuit is very appropriate to further develop into an integrated circuit. Moreover, the proposed circuit enables easy cascading in voltage-mode, due to high-input impedances. The PSPICE simulation results are depicted. The given results agree well with the theoretical anticipation. The power consumption is approximately 4.08mW at ±2.5V power supply voltages.

This article presents the problem of finite time reconstruction of the state and operating mode for a class of non-linear switched systems. The proposed method is based on the non-homogeneous high-order sliding mode approach and it is able to reconstruct both the state and operating mode of the switched system based only on measurable outputs. The observability is derived in terms of certain geometric restrictions on the vector fields of the switched system that require the availability of all its modes. The method does not require the system to be transformed to any normal form. Simulation results support the proposed method.

Artificial Immune Systems (AISs) are composed of techniques inspired by immunology. The clonal selection principle ensures the organism adaptation to fight invading antigens by an immune response activated by the binding of antigens and antibodies. As an immune response can be elicited even when the binding between an antigen and an antibody is not perfect, an approximate binding might suffice, and a Fuzzy Logic mechanism might be the most appropriate mechanism to control such process. This paper presents a novel hybrid model based on concepts of Immune and Fuzzy Systems with applications to pattern recognition problems. The preliminary results obtained here suggest the proposed model is a promising pattern recognition tool.
