REALIZATION OF KHN AND TT FILTERS USING DDCCTA BLOCK
A new active building block for analog signal processing, namely, Differential Difference Current Conveyor Transconductance Amplifier (DDCCTA) provides the possibility of inbuilt electronic tuning of the parameters of the analog function circuits to be implemented. This block is modified and the performance is checked through PSPICE simulations. A modified block is utilized to realize the KHN and TT filters. The proposed realizations use three DDCCTA for the KHN filter and only one DDCCTA for the TT filter circuit. Also, the resulted realizations are tested via PSPICE simulations.

Design and Implementation of Impulse Radio Ultra-Wideband Transmitter
This paper illustrates the simulation, implementation and testing of an UWB transmitter based on Step Recovery Diode (SRD). For testing purposes, a square wave generator has been also implemented based on Colpitts oscillator and a clipping circuit that was used to trigger the monocycle pulse generator. The simulated output is a monocycle pulse waveform with 300 ps pulse width and acceptable symmetry in both amplitude and shape. Integrating the UWB transmitter and the Colpitts oscillator, the achieved output from this integration after implementation is a monocycle pulse waveform with 420 ps pulse width and acceptable symmetry in both amplitude and shape.

Acquisition and Analysis of Electrocardiogram Waveforms with Diagnosis Transmission through Short Message Service Communication System
In this study, we integrated the electrocardiogram waveform acquisition, analysis and diagnosis transmission into a single monitoring system. The electrocardiogram monitoring system is divided into 3 stages, namely the data acquisition stage, the decision making stage and the alerting system stage. We used a low-pass Butterworth filter in the data acquisition stage for removing the artifacts that introduce noise to the electrocardiogram waveform after the analog-to-digital conversion. In the decisionmaking stage, we implemented the zero crossing algorithm for measuring the different segments of the electrocardiogram waveform. And in the alerting system stage, the diagnosis was transmitted to a mobile phone capable of recognizing attention commands via short messaging system. In this study, the integration of the electrocardiogram waveforms acquisition, analysis and diagnosis transmission into a single monitoring system has been successfully implemented. This monitoring system has demonstrated the capability to measure and detect heart rate and heart rhythm respectively. In a bigger picture, an individual can implement this improvised monitoring system using apersonal computer interfaced with a mobile phone.

A Microcontroller-Based Heart Sounds and Murmurs Generator Using Discrete Wavelet Transform
The most important problem of biomedical engineering either for teaching or research activities is how to obtain data of patients with different clinical situations, because it is difficult to find unhealthy volunteers and also to get ethical approval for any experimental test on patients. Hence, this paper presents a practical generator of heart sounds and murmurs for educational and research purposes. The developed generator produces graphical representations of normal and two abnormal heart sounds, which are aortic stenosis and mitral insufficient. Three datasets of real heart sounds have been preprocessed using discrete wavelet transform, in order to reduce the noise and decompose these cardiac signals to the third approximated level based on Daubechies four-coefficient wavelet. For designation and implementation of the heart sounds generator, the ATmega 2560 microcontroller was carefully chosen to produce the output of all preprocessed datasets. The developed microcontroller-based generator showed successfully different cases of the heart sounds and murmurs, allowing to be used further for testing new automatic classification methods of cardiac valvediseases.

AN ARDUINO BASED HOME AUTOMATION SYSTEM
Security is becoming an important issue everywhere. Home security is becoming necessary nowadays as the possibilities of intrusion are increasing day by day. Safety from theft, leaking of raw gas and fire are the most important requirements of home security system for people. A traditional home security system gives the signals in terms of alarm. However, the GSM (Global System for Mobile communications) based security systems provides enhanced security as whenever a signal from sensor occurs, a text message is sent to a desired number to take necessary actions. This project mainly focuses on the security of a home when the user is away from the place.

A Low-Power Low-Noise Neural recording Bioamplifier
This paper presents a low-voltage low-power low-noise amplifier suitable for neural recording applications. The amplifier is able to operate under a 1V supply by alleviating the tradeoff between the noise and the voltage headroom. The amplifier is based on a gm-cell, such that its effective transconductance is not a function of the bias current. As a result the noise contribution of the output transistors can be decreased without increasing the bias current. This bioamplifier rejects DC offset voltage using active low frequency suppression instead of AC coupling capacitors to achieve reduced-size and higher input impedance. The bioamplifier is designed for neural recording of action potentials and simulated in a 130 nm CMOS process. The amplifier consumes 5.2 μW from 1V supply voltage. The input referred noise is 4.7 μVrms. The amplifier has a Bandwidth (BW) from 110 Hz to 9.7 kHz.

Target Signatures and Pose Estimation
The paper discusses an important class of defense and commercial applications in the context of Ground Target (Object) Identification, Classification, and Tracking. The data base of target digital signatures is assembled and formed for a full spatial circle (360 degrees) analysis from such sources as High Resolution Radar and Synthetic Aperture Radar. These digital signatures are analized from which various spatial as well as frequency (wavelet) characteristics of the targets are formed and interpreted, in order to make good estimate of target pose angle. This angle is key for tracking maneouvering targets. Various statistical measures are obtained from digital signatures to assist in pose angle estimation. We also use certain geometrical considerations to determine an initial pose estimate which is the refined using a variety of correlation coefficients. Expected precision of pose estimate is within few degrees, i.e. within few neighboring target signatures. The paper presents several real life ground target signatures as well as several simulated signatures to illustrate our approach.

A Real Time Control System Simulation Model Based on LabVIEW Graphical Programming Language
Embedded control system typically requires an architecture that is designed for reliability and deterministic performance. As a result, real time control system requires processes dedicated to system status monitoring, error handling and watchdog timers. This paper present a six degree-of-freedom (6-DOF) missile model implemented using structured graphical model building blocks. This model illustrates how a graphical representation of a missile model leads to a much clearer representation of the original mathematical model. The LabVIEW graphical programming software and collocate the Real Time/ (6-DOF) model software module are used to establish the missile behavior and nature which integrate the software and hardware equipment. LabVIEW includes tools for low-level system debugging and precise execution timing so that it can increase the flexibility and development of the missiles. Real time simulation is growing in its importance to the success of these systems.A validation of the developed model design is performed through software in loop simulation (SIL). This is to ensure the safety and economics, as the real flight test cannot easily be done.

A new Algorithm for Traffic Congestion Detection using Vehicular Ad hoc Networks
Traffic Congestion in Egypt roads is the same problem facing many cities around the world where traffic congestion is awell-known economic and social problem generating significant costs and safety challenges, and increasing pollution in the cities. Current Conventional infrastructure based solutions to detect traffic congestion, such as surveillance cameras and road surface inductive loops, have the limitations of high deployment costs and limited coverage. This paper contributes towards the development of distributed and cooperative vehicular traffic congestion detection by proposing a new vehicle-to-vehicle (V2V) congestion detection algorithm based on the IEEE 802.11p standard. The new algorithm allows vehicles to be self-aware of the traffic in the city roads, performing congestion detection based on speed monitoring and exchanging traffic information with the surrounding vehicles. Exchanging is achieved using adaptive single-hop broadcasting which depends on the level of congestion. The paper presents the congestion detection algorithm and the cooperative communication in detail, and presents performance evaluation using large-scale simulation in Veins framework based on OMNeT++ simulator and SUMO vehicular mobility simulator. Results show that precise congestion detection and quantification can be achieved using a significantly decreased number of exchanged messages allowing more vehicles to be aware of congestion and be able to avoid it.

Spyware Detection by Extracting and Selecting Features in Executable Files
Spyware detection techniques have been presented using three approaches; signature-based, behavior-based, and specification-based. These approaches failed in detecting new spyware. Data mining is a new approach in detecting spyware that has the ability to detect new spyware or mutated effects of existing spyware. The main challenges in designing anti-spyware systems using data mining techniques are in extracting and selecting the most strong and significant features from spyware data set. In this paper a new approach of extracting and selecting features is proposed. In this approach, the unique features are extracted from all executable files in each class type. Then the selection of the strongest features is done based on the occurrence or the frequency of the features in the data set. The experimental results of the proposed approach outperform all the previous competing approaches.

Global Social Event Extraction and Analysis by Processing Online News
The understanding of global social pattern can benefit the society operation a lot, including the domestic social governance, international situation awareness, risk assessment and forecasting, conflict resolution, crisis response and future policy planning. As the development of Internet, hundreds of millions of news could be found online every day, reporting the social events around the world, including political events, diplomatic events, cultural events, natural disasters, etc. However, by manual reading and analyzing, it is too difficult to deal with the vast amount of data and obtain valuable information quickly. Thus, in this paper we investigate the global social event extraction and analysis method based on the automatic processing of online news, including 1) event model building, 2) event information extraction and automatic classification based on English news text, 3) global social dynamic analysis and visualization based on event data. Finally, we constructed the method on the real global news data collected from more than 200 sitesto evaluate their performance and interpret some underlying insights of the results.

Low energy building design: Heating, ventilation and air conditioning
The move towards a de-carbonised world, driven partly by climate science and partly by the business opportunities it offers, will need the promotion of environmentally friendly alternatives, if an acceptable stabilisation level of atmospheric carbon dioxide is to be achieved. This requires the harnessing and use of natural resources that produce no airpollution or greenhouse gases and provides comfortable coexistence of human, livestock, and plants. This study reviews the energy-using technologies based on natural resources, which are available to and applicable in the farming industry. Integral concept for buildings with both excellent indoor environment control and sustainable environmental impact are reported in the present communication. Techniques considered are hybrid (controlled natural and mechanical) ventilation including night ventilation, thermo-active building mass systems with free cooling in a cooling tower, and air intake via ground heat exchangers. Special emphasis is put on ventilation concepts utilising ambient energy from air ground and other renewable energy sources, and on the interaction with heating and cooling. It has been observed that for bothresidential and office buildings, the electricity demand of ventilation systems is related to the overall demand of the building and the potential of photovoltaic systems and advanced cogeneration units. The focus of the world’s attention on environmental issues in recent years has stimulated response in many countries, which have led to a closer examination of energy conservation strategies for conventional fossil fuels. One way of reducing building energy consumption is to design buildings, which are more economical in their use of energy for heating, lighting, cooling, ventilation and hot water supply. Passive measures, particularly natural or hybrid ventilation rather than air-conditioning, can dramatically reduce primary energy consumption. However, exploitation of renewable energy in buildings and agricultural greenhouses can, also, significantly contribute towards reducing dependency on fossil fuels. This article describes various designs of low energy buildings. It also, outlines the effect of dense urban building nature on energy consumption, and its contribution to climate change. Measures, which would help to save energy in buildings, are also presented.

Design and Construction of Photovoltaic Biomass Hybrid Energy Power System to Supply A Residence in Egypt
Hybrid energy system has been seen as an excellent solution for electrification of rural place where the grid extension is difficult and economically not feasible. The use of renewable energy sources is becoming very necessary due to the limited reserves of fossil fuels and global environmental concerns for the production of electrical power generation and utilization. Solar energy is the most type of RESS pertaining the meteorological conditions of Egypt. This is due to the sunrise from 3000- 4000 hours/year with average insulations of 5-7 kwh/m2/day in all regions of Egypt. Also, photovoltaic (PV) power system is one of the most technologies used for conversion solar energy into electricity. Also, Biomass resources in Egypt that can be used for energy production are classified into the following categories: non- Plantation biomass, fuel crops (energy plantations) and municipal waste. The estimated total amount of biomass is of the order of 60 million ton/y; their gross calorific value is about 855 million GJ, which is equivalent to about 20 million toe/y. On the other hand, the energy storage (ES) is also incorporated which could help cut electricity demand during peak periods and smoothing variations in power generation by variable solar power. Solar PV and biomass with battery and converter are considered for the hybrid system. A case study was done in a rural village in Egypt. The main task is to find the suitablecomponent size and operation strategy for system which results would lead to the design and planning a hybrid energy system.The above concerns led to a desire to investigate the feasibility study of PV-biomassbatterystorage based generator connected to grid, A study was conducted by collectingthe solar radiation data, an average annual solar radiation was compared and a rankingsystem was performed. This system has a number of advantages over conventionalpower generation technologies. This paper depicts the different system components and their optimal combination forthe efficient generation of electrical energy exploiting locally available resources.In this paper, a proposed approach has been introduced and applied for planning of PVbiomasssystems on the electric utility of residential load in Egypt.This approach includes a model for sizing of PV-biomass-battery storage systemsinteractivethe electric utility grid and evaluating the generation of these systems. Also,a suggested model is presented and applied to assess the impact of this generation thecapacity and energy displacement of conventional power supply (CPS), reduction inpollution and energy tariffs of the study electric utility. Learning mechanism utilizes areference model that describes the desired performance. Finally, comparative analysisbetween the two developed controllers is conducted. It discusses the advantages anddisadvantages of each controller algorithm.

Voltage Stability Investigation of the Egyptian Grid With High Penetration Level of Wind Energy During Steady State and Transient
The large penetration level of wind farms might have deleterious effects on the voltage stability of the electric network.This is because wind farms absorb reactive power from the transmission network and an observable drop in bus voltagesoccur. To mitigate this effect, system must be studied under steady-state and transient conditions. The main objective of this study is to analyze the voltage stability of the Egyptian Electrical Network with large scale wind power under normal condition, under single contingency (N-1) and under transient condition. The single contingency is defined as theloss of any transmission line, transformer, or generator. In addition, the paper determines the size of reactive powercompensation devices (capacitors or STATCOM) that should be installed at weak buses to prevent the voltage collapse during normal and transient states.

Innovative Design & Manufacturing Techniques for Cost Effective & Superior Performance Power Transformers
The critical importance of power transformers in any power system can never be over emphasized. The transformer design and manufacturing techniques have remained more or less the same for almost 150 years. But in recent times continuous efforts to achieve energy efficiency and cost effectiveness without compromising the electrical performance of the system has compelled power engineers to move ahead from conventional transformer design and manufacturing techniques to next generation concepts thus achieving a balance of long term monetary savings and superior performance which was not possible a couple of decades ago. The aim of this research paper is to introduce new design and manufacturing techniques which are evolving to give rise of smarter use of new materials thereby changing the physical construction of traditional transformer. The paper also presents the practical advantages of the emergingdesigns and manufacturing techniques through theoretical design calculations and practical case studies.

Impact of SVC on Voltage Stability of HWF Wind Farm during Grid Disturbance
The continuous increase in the pollution level and fuel price lead to increase the using of renewable energy sources especially wind energy. Due to the increase in wind energy penetration into electrical grid, installing wind farms faces many challenges. Continuity of wind farms connection to grid or at least reconnected after clearance of grid faults isimportant challenge. To overcome these challenges Flexible AC transmission systems (FACTS) elements are used as auxiliary equipment. This paper studies the impact of static var compensator (SVC) as one of FACTS family members on voltage stability of hybrid wind farm (HWF) during some grid disturbance such as over voltage, voltage sage, single to ground fault and three phase faults. This hybrid wind farm is consisting of an equal number of Squirrel Cage Induction Generator (SCIG) and Double Fed Induction Generator (DFIG). With this combination, the main benefits of SCIG andDFIG are collected. Where, SCIG is considered cheap with great effect on system stability especially when it operates without shunt compensator while DFIG can be operated with more stability contributes in the stability of interconnected grid. But DFIG is considered very expensive comparing with SCIG. The current paper presents a comprehensive comparison of recent hybrid wind farm with and without SVC during different types of grid disturbance. All test cases are carried out using MATLAB SIMULINK program.

Energy Efficiency Based Resource Allocation Scheme for Cooperative Cognitive Radio Networks
Cooperative communication in cognitive radio networks has been introduced as an important and efficient techniqueto improve the transmission performance of PUs or SUs. In this paper, we consider a cooperative cognitive radio network(CCRN) consisting of multiple primary users (PUs) and multiple secondary users (SUs), where each PU can choose one SUas its relay node. To encourage the forwarding behavior of the SUs, PUs lease a fraction of their allocated spectrum tothe corresponding relay SUs, so that the SUs are capable of transmitting their own data packets. A centralized resourcemanagement architecture is introduced and an energy efficiency based relay selection and power allocation scheme is proposed for the PUs and SUs. The optimization problem is formulated and solved based on a modified Kuhn-Munkres bipartite matching algorithm. Simulation results demonstrate the effectiveness of the proposed scheme.

A HYBRID APPROACH TO CHARGE MOBILE PHONE BATTERY BY SOUND ENERGY
This paper describes charging of mobile phones by making use of sound. Basically here the sound energy is converted into electrical energy; the main principle involved in this project is piezoelectric effect which is the conversion of mechanical force or stress into electrical energy. The Zinc Oxide strands are interceded between two electrodes in this system. The sound absorption pad is placed upon the interceded zinc oxide electrodes. When the generated mechanical waves in the form of sound waves strike the sound absorption pad, vibration occurs. This results in the flexing of the zinc oxide wires. The compressions and rare fractions are due to the sensitivity of the Zno. A nano generator is placed between the sandwiched zinc oxide electrodes. The compressions and rare fractions are given to the nano generator. The nanogenerator converts the given mechanical energy into electrical energy. The generated electrical energy is used to charge the battery.

Target Localization from a UAV Using 3D Terrain Engine
We present a new approach for localizing a ground target from a UAV using 3D terrain engine. We use inaccurate auxiliary sensors on the UAV to obtain an approximate measurement of the camera pose, we use this pose to move the virtual camera inside the engine, and then automatically we find multiple matches between the two images to find the 3D coordinates of the matches using 3D terrain engine. Finally, we test the coplanarity of the 3D points under the camera, depending on this test, we use coplanar or non-coplanar algorithm to estimate accurate global camera pose. The accurate pose is used for localizing targets seen in the image by transmitting a virtual ray from a pixel according to the camera pose until intersect the 3D terrain model in the requested point. We tested the proposed approach on a synthetic and real data. Experimental results proved the feasibility and robustness of the proposed approach and the precision is thesame order as the 3D terrain engine.

On Frequency Tuning of Inverted F Antenna
Internal antennas are widely used in mobile wireless communication devices like smart phones, which have been a major incentive of internal antenna research and design during the last decade, where new designs with wider frequency bands have been introduced; single-band devices have developed into multiband and multimode terminals. Although the average terminal size has decreased drastically, the internal antennas have been designed into standard solutions, to meet the new design requirements, taking into consideration the strict limitations set on the energy absorbed by the users of mobile devices. In this paper, a model for frequency tunable ferrite-based Inverted F Antenna is proposed by altering the permeability of the ferrite material.

Error Control for a Designed State Estimator Function Block of Foundation Fieldbus
Design and simulation of a Foundation Fieldbus State Estimator Function Block (FFSEFB), which can control and minimize the system estimated states' error is proposed in this paper. Due to the importance of the foundation fieldbus systems in manufacturing field, there is a great need for extending their uploaded signals data capacity with high accuracy. A state estimator function block is designed, simulated and analyzed using Matlab/Simulink program to be adapted with a foundation fieldbus of any dynamic system. The designed block contains an adapted PI controller to eliminate the estimated error and ensures a smooth stable block response. The adapted controller block is added in different locations to eliminate the error results from the estate estimator. The controller parameters are changed according to the system input signal to ensure over-damped estimated output signal with zero error. Artificial Neural Network (ANN) technique is utilized in controller parameters determination. The developed intelligent controlled state estimator function block is tested on a 3rd order dynamic system, and the results presents satisfying output. The block design and optimization using Matlab/Simulink and is implemented to an impeded system.

Patrolling Operation Using Functional Heterogeneous Two-Wheeled Mobile Robots and Viewpoints
In this paper, the patrolling operation using two-wheeled mobile robots for monitoring a given area is considered. The two-wheeled mobile robots are considered to be functionally heterogeneous while visiting a set of viewpoints which are considered heterogeneous as well. The problem is typically related to the well-known Travelling Salesman Problem.The functionally heterogeneous two-wheeled mobile robots will only be able to visit the view points that correspond to their heterogeneous functionalities. This could be related to their heterogeneous monitoring capabilities. It is required to obtain the optimal overall minimum travel distance while preserving the constraints of the heterogeneous monitoring functionality to have the most efficient patrolling performance. A new formulation is introduced using mixed-integer programing with simulations to present the exact optimal trajectories that can represent such problems.

Swinging Tension sensor and Control Structure for Gyroscope Fiber Winding Process
One of the common applications of optical fiber coils is optical gyroscope in which optical fiber has tiny cross-section (order of 100 micro meters). Accordingly, with such characteristics, it is required to maintain tension forces applied to fiber during winding process within very low limits. This paper proposes tension sensor and control structure to achieve high precision of fiber tension during winding process. The advantage of the proposed structure of tension sensing and control mechanism is to relax the control objective. Hence, the proposed mechanism allows the use of high torque motors with slow dynamics and large time constant (required for driving large inertia supply spool), yet achieve high transient performance. In this paper, the proposed tension sensing and control mechanism is introduced, its mathematical model is developed and model accuracy is discussed. A conventional PID controller is introduced in tension control loop to verify the developed model transient performance. The simulation results are presented. The results show the validity of the proposed mechanism and it mathematical model.

Pyroelectric Parameters Measurement of Infrared Sensor Based on PANICSA/ PVDF/BaTiO3 Composite Films
An infrared sensor based on composite of polyaniline/polyvinylidene fluoride (PANI/PVDF)/ barium titanate (BaTiO3) with different weight percentages (25, 50, 70 and 100) of BaTiO3 has been fabricated. PANI doped with camphor sulfonic acid (CSA) was prepared chemically. Electrical measurements such as electrical conductivity and pyroelectric current and coefficient of these composites were performed. It was found that the pyroelectric coefficient increases with increasing of the weight percentage of BaTiO3. The behavior of electrical conductivity of PANI-CSA/PVDF/BaTiO3 composite films with different weight percentages of BaTiO3 was followed up the percolation theory. The percolation threshold value of PANICSA/PVDF/BaTiO3 composite films was found at 25 wt.% of BaTiO3. The conductivity of the composite films was increased from 4.08×10-8 S/cm 0 wt.% of BaTiO3 to 8.84×10-6 S/cm at 100 wt.% of BaTiO3. The pyroelectric coefficient values were enhanced from 2.35×10-5 to 1.27×10-3 C/m2˚C at 0 wt.% and 100 wt.% of BaTiO3, respectively.

AUTOMATIC SELECTION OF OVERLAPPING STRIP PAIRS/REGIONS FOR OPTIMIZED LIDAR SYSTEM CALIBRATION
Recently, laser scanning systems (airborne and terrestrial mobile mapping systems) have been established as a leading technology for collecting high density 3D information from an object's surface. The availability of generated surface models is very important for various industrial, military, environmental, and public applications. The accuracy of the derived point cloud coordinates from a LiDAR system is affected by inherent systematic and random errors. The impact of random errors depends on the precision of the system’s measurements, which comprise position and orientation information from the GPS/INS unit, mirror angles, and ranges. On the other hand, systematic errors are mainly caused by biases in the mounting parameters (i.e., lever arm offset and boresight angles) relating the system components as well as biases in the system measurements (e.g., ranges and mirror angles). In order to ensure the geometric quality of the collected point cloud, the LiDAR systems should undergo a rigorous calibration procedure to estimate the system parameters that minimize the discrepancies between conjugate surface elements in overlapping LiDAR strips. The main objective of this paper is to look into an existing LiDAR system calibration technique, which is based on manual selection of overlapping regions between LiDAR strips and how to increase the efficiency of this technique by automatic selection of appropriate overlapping strip pairs, which should achieve the minimum optimal flight configuration that maximizes the impact of the discrepancies among conjugate surface elements in overlapping strips as well as automatic selection of regions within the appropriate overlapping strip pairs. The methodology of the proposed technique can be summarized as follows: first, the LiDAR strip pairs are grouped based on the flight configuration; second, appropriate overlapping strip pairs from each group is automatically selected; third, regions within the appropriate overlapping strip pairs are automatically selected based on their angles (slopes and aspects) and distribution; finally, the calibration procedure is applied. Theexperimental results have shown that the quality of the estimated parameters using the automatic selection are quite comparable to the estimated parameters using the manual selection while the proposed method is fully automated, and much faster.

Nanotechnology applied to Reneweable Energy
Lately, an important application for Nanotechnology is renewable energy. Scientists and engineers have discovered that by using this technology efficiency, cost, size, and weight are improved directly, and the environment and green energy are improved indirectly. Benefits such as these make the investment of capital in the research and development of nanotechnology a top priority element, such as in the strategic European plan. An important subfield of nanotechnology related to energy is nanofabrication. Nanofabrication is the process of designing and creating devices on the nanoscale. Creating devices smaller than 100 nanometers opens many doors for the development of new ways to capture, store, and transfer energy. The inherent level of control that nanofabrication could give scientists and engineers would be critical insolving many of the problems the world is facing today with the current generation of energy technologies. Another current problem is the cost of nanofabrication.

Chemically Reduced Graphene Oxide as Electrodes for Energy Storage Applications
Supercapacitors have attracted increasing attention due to their widespread applications, such as hybrid electric vehicles, power tools, portable electronic equipment and other devices. Using larger surface area of graphene electrodes and thinner dielectrics to achieve larger capacitances is a new trend for increasing capacitance of supercapacitors. This allows for energy densities greater than those of conventional capacitors and power densities greater than those of batteries.. In this paper, graphene oxide was synthesized by improved Hummers method. polyaniline PANI/grapheneoxide (GO) nanocomposite electrode materials were prepared from aniline (ANI), GO and ammoniumpersulfate (APS) by insitu chemical polymerization in ice bath. GO in composite was reduced for 5h and 20h. The crystal structure and the surface topography of all materials were characterized by Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopy. The electrochemical properties were evaluated by cyclic voltammetry (CV), charge-discharge measurements, electrical impedance spectroscopy (EIS) and a four-point probe, respectively. The results show that with increasing reduction time, the oxygen content on the surface of GO was decreased, leading to increased ID/IG ratio in the Raman spectra of GO and increased conductivity of composite. Consequently, the capacitance properties of RGO/PANI composites could be significantly improved by the reduction of GO for 20h. The GO /PANI composite reduced for 20h had a specific capacitance as high as 1405.68 F/g at scan rate of 1 mV/s compared with 291.73 F/g for pristine graphene film.

Fabrication of Asymmetric Supercapacitor Using Aqueous and Polymer Electrolytes for Energy Storage
Supercapacitors represent an attractive alternative for portable electronics and automotive applications due to their high capacitance, specific power and extended life. In fact, the growing demand of portable systems and hybrid electric vehicles, memory protection in CMOS, logic circuit, VCRs, CD players, PCs, UPS in security alarm systems, remote sensing, smoke detectors, etc. require high power in short-term pulses. So, in the last 20 years, supercapacitors have been required for the development of large and small devices driven by electrical power. In this paper, asymmetric supercapacitors with high energy density were successfully fabricated using graphene as negative electrode and polyaniline as positive electrode. The weight of active material was 5.6 mg. The surface topography was characterized by scanning electron microscopy (SEM). The electrochemical properties of the composite were evaluated by cyclic voltammetry (CV), charge-discharge measurements and electrical impedance spectroscopy (EIS). The separator was a filter paper soaked in aqueous potassium hydroxide (6M).This enhances both the specific capacitance to 620.76 F/g at scan rate of 1 mV/s and the energy density to 86.22Wh/kg. Another low leakage supercapacitor was fabricated using polyvinyl alcohol (PVA) separator and 6 mole potassium hydroxide salt with specific capacitance of 220.35 F/g at scan rate of 1 mV/s.
