A computer information processor processes data to create clear and predictable results. The processing may include the acquisition,
recording, assembly, retrieval, or dissemination of information. For example, in printing a text file, an information
processor assigns to translate and present the digital information for a printed form.
The businesses and governments seek to be able to process a large amount of information since decades ago. Those data
were obtained from the statistical or calculated information. The desire to travel into space further fueled the need to process
massive data and the information processing revolution gained more momentum. The 21st century has seen an explosion of
data and the amount of information processed every day has been rocketing. in ascending order of numbers and millions of
software applications. Trillions of information bytes are processed every minute by hundreds of satellites, millions of software
applications, and billions of devices.. Information processing is still rapidly evolving since growing systems and diversified
ownerships are creating an increasing amount of globally processed information.

Wireless Sensor networks (WSNs) can connect the physical world and the cyberspace, which create an environment for
growing new smart applications. However, WSNs need better resilience as they may be deployed in failure-prone environments,
and WSN nodes easily fail due to unreliable wireless connections, malicious attacks and resource-constrained features.

Dual Band Wireless Applications”. In this paper, the design of a dual-band microstrip patch antenna with operating
frequencies of 2.16 GHz and 2.79 GHz was proposed. The proposed antenna design is based on the defected ground
structure and rectangular patch with corner cuts. The presented antenna structure was simulated and optimized using the
CST microwave studio software. The antenna resonated at 2.16 GHz and 2.79 GHz. The bandwidth of the proposed
antenna was 2.08 GHz-2.25 GHz at center frequency 2.16 GHz and 2.7 GHz-2.87 GHz at center frequency 2.79 GHz. The
optimized antenna model was fabricated and measured which was found suitable for dual-band wireless applications.
7. Swati Bhalaik, Ashutosh Sharma, Rajiv Kumar and Neeru Sharma contributed an article titled “Performance Modeling
and Analysis of WDM Optical Networks under Wavelength Continuity Constraint using MILP”. In this article, the authors
found an optimal path between two end-users and allocated an available wavelength to the chosen path for the successful
data transmission. The comparative results of the proposed and existing mathematical models showed that the proposed
algorithm outperformed in terms of various performance parameters. Finally, it was concluded that network congestion
was reduced marginally in the overall performance of the network.
8. Amit Sharma and Pradeep Kumar Singh contributed an article titled “Taxonomy on Localization Issues and Challenges in

10. Amit Prakash, Dilip Kumar Yadav and Arvind Choubey contributed an article titled “A Survey of Multistage Interconnection
Networks”. This paper was an an extensive survey of multistage interconnection networks. A broad classification of
multistage interconnection networks based on network functionality, reliability and fault tolerance was presented in order
to emphasize the important principles which differentiate between the network architectures. The various multistage interconnection
network designs provided high performance, availability, throughput, lower latency, less power consumption
along with improved fault-tolerance and reliability. However, there is a rising demand for new fault-tolerant and reliable
multistage interconnection networks.
11. Ramanpreet Kaur, Bikrampal Kaur and Ruchi Pasricha contributed an article titled “A Study of Wireless Body Area Networks
and its Routing Protocols for Healthcare Environment”. The aim of this paper was to present an essential depiction
of WBAN development in medical and non- medical applications. It was found that QoS aware protocols were employed
specifically for critical applications. While if we consider radiation imparted from the sensors and tissue protection of the
human body, the thermal aware routing protocol was found to be the solution. Another important conclusion of this paper
is that the various protocols do not provide an optimal solution for selecting the forward node during routing and this solution
primarily depends on residual energy of the nodes and distance of the node from the sink.

Analysis of Tilted Time Window and Support Vector Machine based Learning Object Ranking Method”. This paper proposed
and implemented the Learning Objectives (LO) ranking and retrieval algorithm based on the Tilted Time window
and the Support Vector Machine utilizing both the methods. The proposed model was implemented for the NCBI data-set
and MAT Lab. The experiments were carried out on the NCBI dataset, and LO weights were assigned to be relevant and
non - relevant for a given user query according to the Tilted Time series and the Cosine similarity score. Results showed
that the proposed model has much better accuracy.

Welcome to the special issue on “Grid Integration of Renewable Energy Sources” in Recent Advances
in Electrical and Electronics Engineering (EENG). EENG is a peer-reviewed journal that
considers both Research and review based papers.
In most of the countries, renewable energy sources have touched grid parity. The key to increase
the penetration of renewables in the power mix is to have intelligent integration of the renewable
energy sources in the power system network. Integration of intermittent renewable energy sources to
the power system network depends on the scale of power generation. Higher capacity renewables are
connected to the high voltage network and lower capacity renewables are connected in the medium
and low voltage network. There are many technical challenges for integrating the renewables at
higher voltage levels as well as lower voltage levels. It necessitates many technical developments,
for example, in power conditioning devices, to fulfill the necessity for demand flexibility and controllable dispatching of the
The aims of this special issue are to explore the new strategies to overcome the technical challenges of grid integration of
renewable energy sources, such as interconnection (tie-line) capacity among different power system areas (zones), technoeconomic
hybrid system with several types of distributed energy resources, micro-grid and demand-side management capabilities.
IN THIS THEMATIC ISSUE
In the first article, the authors have addressed the problem related to a sudden change in irradiance and temperature, which
causes oscillations in the DC-link voltage, further influencing the dynamic of the system. Feed Forward Compensation (FFC) is
proposed by the authors to overcome the oscillations in the DC-link voltage. The current FFC improves the speed of current
reference estimation and the response of injected currents into the grid. As a consequence, rise time and settling time of the DClink
voltage are reduced. Authors have shared extensive MATLAB simulation results for different conditions to validate the
robustness of the controller under changing environmental conditions.
The second article has proposed a Refined Model Predictive Control (RMPC) strategy for controlling a back-to-back three-
Level (3L) Neutral-Point-Clamped (NPC) converter interfacing a PMSG based WECS with the electric grid. The algorithm
identifies the optimal switching state from the appropriate candidate set of SSs. The performance of RMPC is verified by simulation

Authors have presented the complete simulation modelling and control of Photovoltaic based Distribution Static
Compensator in this article. The configuration proposed by authors has a DSTATCOM, which is fed by a solar photovoltaic
array and PV module to maintain the DC link voltage.
The next article presents the balance of power and voltage of a solid-state transformer for the grid side converter with the
help of the decoupled control technique. Authors of this article have observed that the crossed couple element eliminates by
using decoupling control. It is one of the voltage oriented control techniques. A decoupled control technique allows the bidirectional
power flow and controlling the active power, reactive power and maintaining the steady-state dc interface voltage.
The fifth article proposed the Wavelet Transform (WT) based General Regression Neural Network (GRNN) with statistical
time series input selection technique with an objective to improve the estimation accuracy of wind power. Authors have compared
the results of the proposed model with four different (Naive, Feed Forward Neural Networks, Recurrent Neural Networks
& GRNN) benchmark models on MEAN Absolute Error (MAE) and Mean Absolute Percentage Error (MAPE) accuracy scale.
The last article presented a concept of a PV system integrated with pumped storage for electrification/ implementation in rural
areas. The proposed system operates at Maximum Power Point Tracking (MPPT) without de-rating the PV capacity or any need for ESD. The control philosophy is simple, robust and ensures two modes of operation for pumped storage depending upon
the PV power being generated, load demand and available water level in the lower and upper reservoir. Further, authors
have concluded that to operate the PV system at night with heavy loads, additional ESD may require for better response and

The advances of electronic technologies have opened new opportunities to analyze, manage, and
optimize complex electronic systems dynamically and intelligently. Lots of emerging paradigms have
fundamentally changed the design landscape of complex electronic systems, and have been spurring a
scientific and engineering revolution in the electronic academia and industry. To significantly improve
productivity and performance of conventional electronic hardware and utilities, technology advances in
various areas, such as those in intelligent computing, need to be reexamined and jointly utilized under a
coherent optimization framework to reach an innovative and efficient solution. New models, metrics, and
methodologies in decision theory, evolutionary computing, machine learning, and statistical signal

With the advent of internet times, the combination of the basketball teaching and multimedia becomes
more and more closely, and the use of computer multimedia technology to effectively test the tactical
awareness has been widely concerned. In ‘Research on basketball tactical consciousness aided training
system based on Multimedia Technology’, Based on the analysis of the current development trend of

Harris corner detection based on the characteristic value of the second order matrix to extract corner
features is regarded as one of the most successful algorithms in corner detection. In ‘Harris Corner
Detection Algorithm Optimization.
Based on OTSU’, OTSU algorithm shorted for the maximum variance between clusters can calculates
the maximum variance between the background area and the target area based on the image gray
histograms, and then obtain the adaptive threshold. Because Harris needs to artificially select threshold
and threshold estimation is very difficult, to solve these problems, the OHO algorithm is proposed in this
paper,which aims to optimize the Harris algorithm based on OTSU. The OHO algorithm combines the
characteristics of the high accuracy of Harris algorithm and the adaptive threshold selection of OTSU.
Experiments show that the OHO algorithm can detect more small and authentic corners than traditional
Harris, and it has better adaptability and robustness.
The switched reluctance motor has strong nonlinear feature due to its structure and operation mode, and
the performances and control methods of this new kind of motors are significantly different from those
traditional ones. As a result, the accurate modeling and high performance control of the switched
reluctance motor proves to be very important and has gained widely research. In ‘Switched Reluctance
Motor Control based on Improved Neural network’, a kind of switched reluctance motor based on PID
neural network control method is proposed, which combines artificial fish swarm and particle swarm
optimization to optimize weights and thresholds of BP neural network. Speed response of the improved
BP algorithm has no overshoot, has a smooth transition to the steady state and eliminates the oscillation
phenomena that exists in the PID control. Besides, it reduces the time of transient process to improve the
response speed. Anti-interference ability and robustness is obviously superior to the PID control.
