Electrical control of magnetism of ferromagnetic semiconductor (Ga,Mn)Sb
Yu Nishitani, Masaki Endo, Fumihiro Matsukura, Hideo Ohno

-- Abstract --

Magnetic semiconductors show hole-induced ferromagnetism which enables us to control their magnetic properties by changing their hole concentration electrically by using a field-effect structures. So far, electric-field control of the Curie temperature T_C has been worked mainly on (Ga,Mn)As and (In,Mn)As. In order to investigate the material dependence of effect of the electric fields, we fabricate a field-effect transistor with a (Ga,Mn)Sb channel. A clear modulation of T_C of (Ga,Mn)Sb is observed through the anomalous Hall effect by the application of electric fields, and the relationship between T_C and hole concentration is compared to that of (Ga,Mn)As.

F1J-2
Electric double layer transistor with a thin (Ga,Mn)As channel layer
Masaki Endo, Daichi Chiba, Hidekazu Shimotani, Fumihiro Matsukura, Yoshihiro Iwasa, Hideo Ohno

-- Abstract --

We have demonstrated electrical control of magnetic property in hole-induced ferromagnetic semiconductor (Ga,Mn)As by utilizing an electric double layer transistor structure. We measured the temperature dependence of sheet resistance R_sheet under gate voltages V_G, and determined the Curie temperature T_C at each V_G, from the hump temperature of R_sheet-T curve. The magnitude of modulation of T_C was reached up to 14 K by changing V_G from +4V to -1V.

F1J-3
Properties of GaAs quantum cascade lasers with a metal-metal waveguide
Tsung-Tse Lin, Keita Ohtani, Hideo Ohno

-- Abstract --

Quantum cascade lasers (QCLs) are a compact THz light source utilizing carrier recycling and intersubband transition in quantum wells, which exhibit high optical output power with a narrow linewidth. The implementation of metal-metal waveguides with high optical confinement, small waveguide loss, and large thermal conductivity is critical for improvement of laser performance. Here we investigate properties of GaAs/AlGaAs THz QCLs with a metal-metal waveguide. In order to study the effect of metal properties on laser characteristics, metal-metal waveguides based on three kinds of metals (Au, Cu, and Ag) are fabricated

F1J-4
Gate voltage dependence of nuclear spin relaxation in an n-GaAs quantum well
Masaaki Ono, Hiroomi Kobayashi, Shunichiro Matsuzaka, Yuzo Ohno, Hideo Ohno

-- Abstract --

Optical and electrical manipulation and detection of nuclear spins insemiconductor nanostructures have been of great interest forunderstanding the spin related physics. In this work, we investigatedthe gate voltage dependence of the nuclear spin relaxation andcoherence time in a Schottky-gated n-GaAs/AlGaAs quantum well (QW) bytime-resolved Kerr-rotation measurements combined with the pulsed-rfnuclear magnetic resonance technique. We show that the nuclear spinrelaxation and coherence time decrease with decreasing electrondensity, and get recovered with depletion of the electrons, indicatingthat the hyperfine interaction is enhanced as the electrons becomelocalized in impurities.

Experimental Study on MIMO Performance of Modulated Scattering Antenna Array in Indoor Environment
Lin Wang, Qiang Chen, Qiaowei Yuan, Kunio Sawaya

-- Abstract --

The modulated scattering antenna array (MSAA) is composed of one normal antenna element and several modulated scattering elements (MSEs). In this report, a 2-element MSAA is used as the receiving antenna in 2 by 2 multiple input multiple output (MIMO) system. MIMO performance of MSAA with various array spacing is measured to investigate the relation between the array spacing and the MIMO performance of the MSAA experimentally in the non-line-of-sight (NLOS) indoor environment. It is found that the error vector magnitude (EVM) and the channel capacity which reflect MIMO performance can be affected by the array spacing. The measured results of the MSAA were compared with that of two-dipole antenna array at the same condition.

F1K-3
Optimal Spectrum Selection Probability in Cognitive Radio Networks
Chung-Wei Wang, Li-Chun Wang, Fumiyuki Adachi

-- Abstract --

In this paper, we characterize the spectrum usage behaviors of spectrum handoff in cognitive radio (CR) networks based on the proposed preemptive resume priority (PRP) M/G/1 queueing network model. Spectrum handoff occurs when the primary user appears and its licensed band is occupied by the secondary users. Spectrum handoff procedures aim to help the secondary users vacate the occupied spectrum and search the target channels to resume the unfinished transmission. Within a packet transmission period, it is likely to have multiple spectrum handoffs. Based on theproposed PRP M/G/1 queueing network model, the total service time with multiple handoffs for various traffic arrival rates and service distributions can be evaluated analytically.

Characterization of new promising piezoelectric crystals
Andrey Sotnikov
Leibniz Institute for Solid State and Materials Research Dresden

-- Abstract --

Trigonal Sr₃NbGa₃Si₂O₁₄ (SNGS) and Sr₃TaGa₃Si₂O₁₄ (STGS), hexagonal AlN and tetragonal LiAlO₂ piezoelectric single crystals are of current interest as very promising materials for both bulk- and surface acoustic wave devices like resonators, filters and various sensors. SNGS and STGS belong to the same crystal class as quartz (SiO₂), but compared with SiO₂ they have two-three times higher piezoelectric coefficients. AlN has attractive piezoelectric properties and very high values of sound velocities. As expected, piezoelectric response in SNGS, STGS and AlN crystals can be observed up to very high temperatures.
In this paper, we report on the measurements of elastic, dielectric and piezoelectric constants of SNGS, STGS, AlN and LiAlO₂ big bulk single crystals. The elastic and piezoelectric constants were derived from the velocity data of bulk acoustic waves measured by ultrasonic pulse-echo method using crystals samples of the appropriate orientations. Measurements of some piezoelectric and elastic constants of SNGS and STGS crystals at temperatures up to 940⁰C are also presented.

Multilevel Green's Function Interpolation Approach -- a Review
Chan Chi-Hou
City University of Hong Kong

-- Abstract --

This paper presents a review of our development of a fast computational method for large-scale electromagnetic simulations that coined the multilevel Green's function interpolation method. For low-frequency structures, both the computation time and computer memory requirement scale as O(N). For full-wave EM scattering problems, the computation time scales between O(N) and O(N log N) while the computer memory requirement remains O(N). Difficulties encountered and proposed remedies in the course of the development and refinement of this efficient computational method will be discussed.

Qiong Li
Harbin Institute of Technology

-- Abstract --

As an authentication technique, the imagerobust hash has drawn many attentions. However, thebalance between the “robustness” and “security” criteria ofrobust hash is still an open question. A secure sketch basedimage robust hash scheme is presented in this paper. In suchscheme, there is no need to store the image robust digest inthe database directly. What is more, the matching operationcan be implemented in the cryptographic field. It isdemonstrated that the security of such robust hash scheme isimproved to some degree.

Nonlocal dispersion cancellation using entangled photons
So-Young Baek
Pohang University of Science and Technology (POSTECH)

-- Abstract --

A pair of optical pulses traveling through two dispersivemedia will become broadened and, as a result, thedegree of coincidence between the optical pulses will be reduced.For a pair of entangled photons, however, nonlocaldispersion cancellation in which the dispersion experiencedby one photon cancels the dispersion experienced by the otherphoton is possible. In this paper, we report an experimentaldemonstration of nonlocal dispersion cancellation usingentangled photons. The degree of two-photon coincidenceis shown to increase beyond the limit attainable without entanglement.Our results have important applications in fiberbasedquantum communication and quantum metrology.

Generation and evaluation of polarization-entangled photon pairs using two-period quasi-phase matched LiNbO ₃
Wakana Ueno, Hirofumi Suzuki, Shigehiro Nagano, Atsushi Syouji, Ryosuke Shimizu, Koji Suizu, Keiichi Edamatsu

-- Abstract --

Entanglement is one of the key resources in quantum information technology. Spontaneous parametric down-conversion (SPDC) is the main method so far used to generate entangled pairs of photons. Especially, quasi-phase matching (QPM) technique attracts much attention because it enhances the ability of SPDC. We have designed and fabricated periodically poled LiNbO₃ (PPLN) crystals having two poling periods to generate non-degenerate, polarization-entangled photon pairs. Polarization correlation measurement of the generated photon pairs manifests the entanglement.

Perception of audio-visual spatial disparity in the peripheral visual field
DaeGee Kang, Ryota Miyauchi, Yukio Iwaya, Yo-iti Suzuki

-- Abstract --

An experiment was conducted to investigate possible differences in theperception of spatial coherency between auditory and visual stimuliwhen presented from the central visual field and when presented fromthe periphery. The participant was to judge the spatial coherence ofauditory and visual stimuli presented simultaneously using a method ofpsychophysical scaling. When the visual stimulus was presented fromthe periphery, the auditory and visual stimulus were perceived as iforiginating at the same location if the auditory stimulus waspresented outwards by about five to seven degrees from the physicaldirection of the visual stimulus source. These results suggest thatthe audio-visual spatial integration in the peripheral visual fieldshows a different aspect from that in the central visual field.

Atomic-Layer Doping Characteristics of P in Si Cap Layer Growth Using Si₂H₆ on P Atomic Layer Formed on Si_0.3Ge_0.7/Si(100)
Yohei Chiba, Masao Sakuraba, Bernd Tillack, Junichi Murota

-- Abstract --

In Si cap layer growth at 450 ^oC using Si₂H₆ on P atomic layer formed on Si_0.3Ge_0.7/Si(100), relationship between P incorporation and surface segregation has been investigated. At lower initial P atom amount below about 4x10¹⁴ cm^-2, most of the incorporated P atoms are confined within 1 nm-thick region around heterointerface. However, at higher initial P atom amount than 4x10¹⁴ cm^-2, P surface segregation is enhanced, and the incorporated amount tends to saturate at about 4x10¹⁴ cm^-2. Additionally, by atomic-layer doping, very high carrier concentration of more than 1x10²¹ cm^-3within 1 nm region could be realized.

Heavy N Atomic-Layer Doping in Strained Si_1-xGe_x Epitaxial Films on Si(100) by Ultraclean Low-Pressure CVD
Tomoyuki Kawashima, Masao Sakuraba, Bernd Tillack, Junichi Murota

-- Abstract --

N atomic-layer doping in a nanometer-orderSi/Si_1-xGe_x/Si(100) heterostructure usingultraclean low-pressure chemical vapor deposition and its thermalstability at 650 ^oC were investigated. In theSi_0.5Ge_0.5 epitaxial layer, it is found that a Ndoping dose of 6x10¹⁴ cm^-2 can be confinedwithin an about 1.5 nm-thick region even after 650 ^oC heattreatment in contrast to result for Si with a N dose of6x10¹⁴ cm^-2 which was amorphous. Moreover, it issuggested that the confined N atoms in Si_1-xGe_xpreferentially form Si-N bonds and that formation ofSi₃N₄ is enhanced by the heat treatment at 650^oC.

An appropriate and iterative calculation method to derive of all parameters of the single diode model from a single current-voltage characteristic of a solar cell
Mohammad Maksudur Rahman, Ryota Kojima, Ken-ichi Ishibashi, Yasuo Kimura, Michio Niwano

-- Abstract --

Accurate measurement of all solar cell parameters is an important issue in order to analyze the performance of a solar cell. Here we have proposed a stable method for the derivation of solar cell parameters from a single I-V curve under only the valid assumption for a general solar cell. We applied this method to experimental I-V curves of a dye-sensitized solar cell. The I-V curve was calculated using the values of parameters derived from our method, and was found to be in good agreement with the experimental I-V curve.

Uniaxial magnetocrystalline anisotropy for c -plane oriented Co_100-xGe_x film with pseudo-hcp structure
Shintaro Hinata, Shin Saito, Ryuichi Yanagisawa, Migaku Takahashi

-- Abstract --

Effects of Ge addition into Co sputtered film on uniaxialmagnetocrystalline anisotropy energy (K_u) wereinvestigated. Through the quantitative evaluation of degree ofstacking faults using laboratory-scale in-plane XRD, it was foundthat; 1) Saturation magnetization was monotonously decreased withincreasing Ge content, while K_u took the maximumvalue of 6.3。゜10⁶ erg/cm³ at Ge content of 10at%. 2) -A-B-C-stacking probability, P_fcc, showed10% for pure Co film, while, 1% for Co₉₀Ge₁₀film. 3) Ge addition was found to eliminate stacking faults inCo-based magnetic grains, which was one reason of the enhancement ofK_u for CoGe alloy films.

Reinforcement of exchange biasing of ultra thin antiferromagnetic oxide layer
Kazuya Sawada, Naoki Shimomura, Masaaki Doi, Masashi Sahashi

-- Abstract --

Magnetoelectric (ME) effect has attracted attention for controlling ferromagnetic spins by an applying electric field. However, a thick ME material is needed for realizing the electrically controlled exchange biasing because the blocking temperature (T_B) decreases with thinning the thickness. We have obtained higher T_B for Cr₂O₃-Fe₂O₃ NOL (Nano-Oxide-Layer) even 1 nm of the thickness. In this study the exchange bias field for IrMn/CoFe/NOL/CoFe spin valve (SV) and CoFe/NOL/CoFe trilayer are investigated. As a result, T_B of SV (250K) is higher than that of trilayer (25K). This result suggests that the exchange biasing from IrMn supports the stability of antiferromagnetism.

A Fast Method of Subpixel Image Registration Based on Phase-Only Correlations of Image Projections
XiaoYong Zhang, Masahide Abe, Masayuki Kawamata

-- Abstract --

This paper presents a fast subpixel image registration approach based on the phase-only correlation (POC) of the image projections. The two-dimensional (2-D) POC between two images can be decomposed into two one-dimentional POCs of the image projections along the vertical and the horizontal direction. The subpixel displacements are estimated by fitting the 1-D POCs of image projections as the quadratic curves. Experimental results have shown both the low computational cost and the high-accuracy of our method.

Reference Image Estimation for Flicker and Blotch Detection in a Restoration System of Old Film Sequences
Koki Shoji, Masahide Abe, Masayuki Kawamata

-- Abstract --

This paper proposes an estimation method of a common reference image for flicker and blotch detection in a restoration system of old film sequences which digitized by a film scanner at high resolution. It was redundant to set some reference images for flicker and blotch detection since a conventional restoration system detected flicker and blotch respectively which occurred to old film sequences and removed them. To reduce the redundancy, we set a common reference image for flicker and blotch detection by assuming that flicker and blotch are impulsive and Gaussian noise in temporal direction at each pixel respectively. The experimental result shows that the proposed method reduces the computational complexity of the reference image estimation.

An Image Correction Method Using Image Matching Techniques for Projected Images
Toru Takahashi, Tatsuya Kawano, Takafumi Aoki, Satoshi Kondo

-- Abstract --

This paper proposes an image correction method using image matching techniques for projected images. The image correction of projected images is performed using camera-captured images. In conventional methods, the correspondence between projector and camera images is obtained by projecting special light patterns on a display surface. This paper presents a correspondence search technique without using special light patterns. We employ a snapshot of ordinary image to find projector-camera correspondence. We adopt two image matching techniques: (i) SIFT-based feature matching and (ii) POC-based correspondence search technique. Experimental results show that we can correct projected images effectively using the proposed method.

Preparation of Au Films Deposited on Glass Substrates for the Enhancement of Light Emission from Prism-Coupled STM Junction
Jamal Uddin Ahamed, Tomonori Sanbongi, Satoshi Katano, Yoichi Uehara

-- Abstract --

The purpose of present research is to explore the optical and electronic properties of individual nanostructures with atomic scale spatial resolution by prism-coupled scanning tunneling microscope light emission (STM-LE) spectroscopy. STM-LE is electromagnetically enhanced by the thin Au film deposited on the bottom of a hemispherical prism. In this presentation we have studied the structure of Au substrate using atomic force microscope (AFM) and STM. We found that the morphology of the Au surface strongly depends on the cleanliness of glass substrate and deposition temperature. Dry contact or spin coated method was used for the deposition of carbon nanotube (CNT) on the Au surface. We are now developing a prism-coupled STM light collection system for optical measurements of individual CNT adsorbed on the Au films.

Investigation of H2/CH4 Plasma Composition in Nonmagnetic Growth of Single-Walled Carbon Nanotubes by Plasma Chemical Vapor Deposition
Zohreh Ghorannevis, Toshiaki Kato, Toshiro Kaneko, Rikizo Hatakeyama

-- Abstract --

In situ plasma analysis was performed during the single-walled carbon nanotubes (SWNTs) growth from Au catalyst with plasma chemical vapor deposition (PCVD). The system based on optical emission spectroscopy (OES) dedicated for in situ diagnostics of PCVD processes. SWNTs growth were performed for a various H2 flow rates at an radio frequency (RF) power of 50 W. Au metal particles were found to have catalytic activity for growth of SWNTs under the specific plasma condition. The plasma analysis revealed that the intensity of H」\ and CH radical remarkably increased and decreased by increasing the H2 flow rate, respectively. This indicates that the intensity ratio of CH/Hτ could be useful to optimize the growth condition of SWNTs with Au catalyst.

Akira Sakatoku, Gen Kitagata, Norio Shiratori, Tetsuo Kinoshita

-- Abstract --

In conventional collaborative work environments, provided applicationsare closed in an individual system. Because of this limitation, userscannot composite collaborative work environment freely.To break this limitation, we propose Symbiotic Application CompositionFramework that has affinity between the Digital Space and the RealSpace. Our framework has two features. (1) Users can integrateapplications among several systems. (2) Users reuse applications thatprovided by other users intuitively and flexibly.In this paper, we describe Symbiotic Application CompositionFramework. We discuss support ability for the collaborative work withthis framework. Furthermore, we show design and implementation of theprototype system.

-- Abstract --

In this paper, we describe a communication infrastructure for theagent-oriented middleware in the ubiquitous computing environmentbased on the inter-platform communication mechanism. We propose anadaptive communication mechanism between agent platforms, which canselect communication schemes dynamically and flexibly, according toproperties of the computational environment and requirements of theinter-agent communication. We designed the proposed mechanism andimplemented a prototype system. We also evaluated the system on twotypes of access network. We confirmed that the dynamic selection ofinter-platform communication schemes works effectively according tothe changes of the network resource status.

Design of a Fully-Parallel Content-Addressable Memory Using Phase-Change Devices
Satoru Hanzawa, Takahiro Hanyu

-- Abstract --

A resistive content-addressable memory (CAM) using phase-change devices is proposed. The use of a hierarchical match-line structure and a one-hot-spot block code makes it possible to reduce resistance ratio, β (=R0/R1), for implementing the fully-parallel CAM. In fact, it is demonstrated that a 8nsec-search 72bit-parallel CAM is implemented using phase-change devices whose R0 is more than 12 MΩ and R1 is less than 97 kΩ (i.e., β =123) with maintaining one-day retention.

Design of a Nonvolatile Lookup Table Circuit Based on TMR Logic for an Immediate Wakeup FPGA
Daisuke Suzuki, Masanori Natsui, Takahiro Hanyu

-- Abstract --

This paper presents a nonvolatile lookup-table (LUT) circuit in FPGA using a tunneling magneto-resistive (TMR) device-based logic technology. The circuit is implemented based on logic-in-memory architecture, where TMR devices are distributed over a logic-circuit plane as nonvolatile memory elements. Maximally utilizing a capability of TMR device such as unlimited endurance, scalable write, and small dimension comparable to the employed CMOS technology, a compact and standby-power-free LUT circuit can be obtained.The proposed LUT circuit fabricated by a 0.14・m CMOS/TMR-hybrid process achieves area reduction by 2/3 compared to a conventional SRAM-based one, and immediate wakeup capability.

-- Abstract --

A multiple-valued reconfigurable VLSI suitable for dynamic data-pathcontrol is proposed to use hardware resources efficiently. Hybridarchitecture based on wired programming and dynamic data-path controlis introduced to achieve high utilization ratio of hardware resource.In logic-in-control architecture, each controller is provided near thearithmetic logic circuit, which leads to simple interconnectionsbetween arithmetic logic circuits and controllers. Moreover,superposition of data and control signals is introduced to eliminateskew between data and control signals and interconnection switches forprogramming a routing of the control signal.

TiO2 nanotubes: Formation , Properties and Applications
Patrik Schmuki
University of Erlangen-Nuremberg

-- Abstract --

We report approaches to grow self-organized high aspect ratio titanium oxide nanotubes. Key to obtain highly defined tubes by simple anodization is an optimized and controlled treatment of Ti in fluoride containing solutions. In general, the morphology of porous TiO₂ and of the tubular layers is affected strongly by the electrochemical parameters such as solution pH and anodization voltage. By optimizing the local electrochemical conditions within the tubes layers consisting of highly ordered TiO₂ nanotubes with a length of several 100 micrometers can be grown on Ti surfaces. The diameters that can be obtained range from 20 nm to 200nm - typical wall thicknesses are in the range of 10-20 nm. Novel arrangements (Nanobamboo, nanolace and double walled nanotubes) have been reported. Titanium dioxide is a highly functional material that has numerous interesting properties, for example, in solar energy conversion, catalysis of the decomposition of organic compounds (self-cleaning), wettability and biocompatibility.
We have recently shown that these nanotubular structures show significant solar conversion efficiencies, when dye-sensitized, can be used as a matrix for hydroxyapatite formation to achieve osseointegration with bones, show extremely enhanced visible photoresponse after N-doping, can be used as a highly efficient photocatalyst as a catalyst carrier for Pt/Ru nanoparticles for methanol electrooxidation or as a template for Cu deposition. Further, they show ability to change their hydrophobic/hydrophilic behaviour, free standing nanotube membranes can be produced and size sensitive interactions of biological cells with the nanotubes surface have been reported.
The presentation will not only address the fabrication of self-organized nanotube layers but particularly discuss the latest state in applications.

FPGA Challenges and Opportunities at 40 nm and Beyond
Stephen Brown
Altera Corporation and the University of Toronto

-- Abstract --

FPGA companies are amongst the earliest adoptersof next-generation integrated circuit process technology, as theeconomics of scaling are more favorable for FPGAs than formany other technologies. Moving to advanced processesinvolves many challenges, including power management,device modeling, increasing I/O performance to match thecomputational capacity, and enabling very large designs to becompleted quickly. In this paper, we highlight the economicand technological advantages of moving FPGAs to moreadvanced processes, and discuss the techniques Altera is usingto overcome the challenges that come with process scaling.

320 Gbit/s/ch WDM Transmission over 525 km Using Time-domain Optical Fourier Transformation
Pengyu Guan, Toshihiko Hirooka, Masataka Nakazawa

-- Abstract --

Increasing the bit rate per wavelength channel is an important goal in terms of realizing future ultrahigh-capacity optical networks with a simple configuration, large flexibility, and low power consumption, in which the complexity of wavelength routing at the switching nodes can be alleviated through the need for fewer wavelength channels. In this paper, we present the first long-haul WDM transmission of 320 Gbit/s OTDM signals, where a single-polarization 5x320 Gbit/s (1.6 Tbit/s) C-band WDM signal was successfully transmitted over 525 km using the time-domain OFT technique.

10 Gbit/s photonic crystal fiber transmissions with 1.1 um directly-modulated single-mode VCSEL
Kengo Koizumi, Masato Yoshida, Toshihiro Hirooka, Masataka Nakazawa

-- Abstract --

We demonstrate 10 Gbit/s transmission over a 5 km photonic crystal fiber (PCF) in the 1.1 um band using a directly-modulated single-mode vertical cavity surface emitting laser (VCSEL). A combination of PCF and VCSEL enables us to achieve high-speed transmission at a low cost and with a simple configuration that does not employ optical modulators or amplifiers. Furthermore, the transmission distance was extended to 14 km by using an ytterbium-doped fiber amplifier (YDFA), and a power penalty-free transmission was successfully achieved.

2 Gsymbol/s 64 QAM-OFDM (24 Gbit/s) coherent optical transmission
Tatsunori Omiya, Keisuke Kasai, Masato Yoshida, Masataka Nakazawa

-- Abstract --

Recently, Orthogonal Frequency Division Multiplexing (OFDM) system, that was originally developed in wireless communication, has been intensively studied in optical communication. The multi-carrier transmission of low-speed orthogonal subcarriers enables us to improve both spectral efficiency and dispersion tolerance by adopting high-level subcarrier modulation formats and employing coherent detection in OFDM. So far, 1 Tb/s per channel OFDM transmission and OFDM optical coherent transmission with 32 QAM subcarrier modulation have been reported. In this report, we realize QAM subcarrier modulation up to 64 levels and demonstrate OFDM transmission over a 160 km.

Design & Simulation of Very Efficient Hybrid Renewable Energy Conversion System
Syed Muhammad Raza Kazmi, Hiroki Goto, Hai-Jiao Guo, Osamu Ichinokura

-- Abstract --

This paper presents a hybrid renewable energy conversion systemcombining the wind energy conversion system (WECS) and photovoltaics(PV) energy system. The most remarkable feature is the novelintelligent control system developed for maximum power point tracking(MPPT) of both WECS and PV systems. Owing to the different nature ofWECS and PV systems, their respective novel control algorithms beardifferent strategies for MPPT. The novel control can track the maximumpower point (MPP) despite the sharp changes in the atmosphericconditions or partial shading effects. The simulation results confirmthat the hybrid renewable energy system based on the proposed MPPTcontrol is much faster and more efficient than the one based on theconventional MPPT method.
