Abstract The goal of this paper is (i) adopt fusion of features (ii) determine the best
method of feature selection technique among ant Colony optimisation, artificial
bee colony optimisation and genetic algorithm. The experimental results
reported that ant colony Optimisation is a promising techniques as feature
selection on Keystroke Dynamics as it outperforms in terms of recognition rate
for our inbuilt database where the distance between the keys has been
considered for the password derivation with recognition rate 97.85%. Finally
the results have shown that a small improvement is obtained by fused features,
which suggest that an effective fusion is necessary. More >

Abstract Medical images are obtained straight from the medical acquisition devices so
that, the image quality becomes poor and may contain noises. Low contrast
and poor quality are the major issues in the production of medical images.
Medical imaging enhancement technology gives way to solve these issues; it
helps the doctors to see the interior portions of the body for early diagnosis,
also it improves the features the visual aspects of an image for a right
diagnosis. This paper proposes a new blend of Particle Swarm Optimization
(PSO) and Accelerated Particle Swarm Optimization (APSO) called Hybrid Partial

Abstract Recognition of human activity is a key element for building intelligent and
pervasive environments. Inhabitants interact with several objects and devices
while performing any activity. Interactive objects and devices convey
information that can be essential factors for activity recognition. Using
embedded sensors with devices or objects, it is possible to get object-use
sequencing data. This approach does not create discomfort to the user than
wearable sensors and has no impact or issue in terms of user privacy than
image sensors. In this paper, we propose a linear model for activity recognition
based on the state-space method. The activities and sensor… More >

techniques, which involve a bit sequence that represents a specified property and
indicates the data items that satisfies this property, are well-known methods to
improve processing time for complex and interactive queries on the read-mostly
or append-only data. This paper proposes an improved bitmap index technique,

Abstract With the spreading of Photovoltaic (PV) grid-connected system, grid-connected
reactive-load compensation and harmonic control is becoming a research focus.
Unipolar and bipolar modulations are widely used in active power filter of PV
grid-connected inverter. Unipolar modulation is good at harmonic, ripples and
efficiency control, while bipolar modulation is good at grid-connected current
control. A comprehensive comparison between the aforementioned modulation
strategies in aspects of basic switching action, effects on operation mode,
current harmonics，efficiency, is done in this paper. Base on it, a hybrid
modulation strategy with the fusion of the unipolar and bipolar modulation is
proposed in this paper. Numerical… More >

Abstract The disadvantages in power system with traditional industrial frequency
transformer can be resolved by Solid State Transformer (SST). Cascaded SST
can be transformerless connected to the high voltage grid. However, the output
performance and reliability of cascaded SST are seriously influenced by DC
voltage balancing problem which exists in cascaded configuration. In this paper,
a DC voltage balancing strategy based on active vector correction is proposed.
This strategy is characterized by on-demand active power and equal reactive
power among modulars. Then, a quantitative analysis method is presented to
validate active power adjusting ability of the traditional and the proposed
strategies.… More >

Abstract With the current trend of deregulation, more power exchange between GENCOs
and DISCOs in different areas exists in the power system. To mitigate the
unscheduled power exchange meets the common interests of GENCOs and
DISCOs, and avoids the power over-loading on tie-lines. However, in the
current control performance standards (CPS), frequency deviations have priority
in the conventional automatic generation control (C-AGC). Thus, a storagebased tie-line control loop (STCL) on the basis of C-AGC (STCL-AGC) is
proposed in this paper, which makes a better tradeoff in the recovery of the
frequency deviations and the unscheduled power exchange. In STCL-AGC,

Abstract Hyperspectral remote sensing, with its narrow band imaging, provides the
potential for fine identification of ground objects, and has unique advantages in
mineral detection. However, the image is nonlinear and the pure pixel is scarce,
so using standard spectrum detection will lead to an increase of the number of
false alarm and missed detection. The density peak algorithm performs well in

is analyzed by computer simulation, and the motion law between each axis of

establish the relationship between the percolation threshold and the Euler

The included angle between adjacent helical wires in the same layer, which is

ratio of each layer wires was formulated into a one-dimensional problem and
golden section method was applied to solve the problem efficiently. Finite
