Software Defined Radios (SDR) is integrated with dynamically configurable software to enable Cognitive Radio (CR) design. Higher Channel densities management and continuous service provision are the performance measures for SDR. Incorporating adaptive modulation capability in sophisticated wireless communication techniques necessitates an Automatic Modulation Recognition for SDR. The abundant demodulation requisite for SDR is not catered sufficiently by available Automatic Modulation Recognition techniques. This paper deals with a novel method of automatic modulation identification for Software defined radio. The proposed technique uses a simple method of appending a unique pilot sequence to each modulated data for identification purpose. This work analyzes the performance of the identifier for typical modulations under noisy conditions and at different Signal to Noise Ratios (SNRs). A pre-processing module is also adapted in the modulation identification technique and performs rejection of noise, normalization, carrier frequency estimation and recovery of complex envelope.Keywords

Automatic modulation recognition for software defined radio (SDR) is a research focused on developing 3G and 4G wireless communications with adaptive modulation capability. The existing automatic modulation recognition technology does not satisfy the seamless demodulation requirement of the SDR. The design of automatic modulation recognition method with reduced computational complexity and fast processing speed is needed. The radio systems are increasingly incorporating dynamically configurable software into software defined radio (SDR) design. The ability to change software after manufacture makes SDR a perfect platform for designing Cognitive Radio (CR). The equipment must handle higher channel densities and must meet a high-availability standard to provide uninterrupted service. In addition, the equipment will be flexible to accommodate various air protocols. The statistical performance of the fast automatic modulation recognition associated with its implementation using the SDR is discussed in this work.Keywords

A comparative study for transforming a slow motion system (SMS) into Fast Motion system (FMS) is presented. Priority inversion problem occurs when multiple tasks are running in parallel and request the access of the resource at the same time thereby making the system response slow. In this study an existing SMS running on LPC 1768 board is transformed to FMS using real time concepts -Mutex in μcos that provides inbuilt solution for priority inversion problem by changing the priority of lowest priority task to highest priority momentarily. In the results section, SMs and FMS results are measured which are dependent on different tasks based on priority levels.Keywords

Computers have a plethora of different applications, spread over a wide spectrum of different branches such as electronic fund transfers, air traffic control, and storage of information in medical systems and so on. In all these security is an important aspect of any operating system and access of information to only properly authorized individuals or processes through the use of special security features should be ensured. The main objective of the proposed self healing scheme is to share and secure the information of any system at the same time. However, sharing and protection are two contradictory goals. Protection programs may be completely isolated from each other by executing them on separate non-networked computer, however, this precludes sharing. The proposed work provides data security based on Dynamic Information Flow Tracking by keeping track of the modified capabilities of the resources. A novel feature of this work is that the proposed architecture allows passive threats to co-exist, thus, making the architecture more user-friendly.Keywords

To reduce energy consumption, adiabatic logic families are used, which utilizes AC voltage supplies to recycle energy of circuits instead of being dissipated as heat, a flip flop is realised using PAL-2N (pass transistor adiabatic logic) logic. Using this sequential circuit is implemented. The energy saving is further attained by including power gating in the circuit. With the help of simulation results, it’s shown that energy loss for this adiabatic sequential circuit with power-gating technique is reduced greatly.- Implementation of FPAA Controller with Programmable Control Law Generator

The speed of a single-phase motor is a highly critical parameter. The speed is typically affected by loads placed on the motor. In this work, a FPAA based variable control law controller is presented for controlling the speed of a motor. The proposed controller has an embedded variable control law functional block. The FPAA with the variable control law help in appropriately altering the guidance laws that characterize the system behavior in the event of system trying to track rapid changes in set point.Keywords

Data transmission increases vastly and hence the crisis in data security arises. The transmitted data are subjected to various proceedings to ensure security. From the usual way of providing security in the presentation layer alone, it is strongly put forth to provide security in the other layers too. This could be done with the help of the Software Hardware co-design. Apart from the Encryption Techniques, small mechanism to screen the trusted users is provided in the Physical layer itself to enrich the strength of the security. Comparison is done with strong encryption and combined weak encryption and hardware technique.Keywords

This paper discusses an embedded reconfigurable architecture to perform error detection and correction in the physical layer in OSI network. Specifically, the three popular self-healing architectures namely, Cyclic Redundancy Check (CRC), Longitudinal redundancy Check (LRC) and Character Stuffing; are implemented in the field programmable gate array (FPGA). Performance metrics are used to assess the feasibility of the designed reconfigurable architecture. Additionally, to justify the hypothesis of single faults and avoid accumulation of undetected errors in FPGAs and memory systems, scrubbing is used. Relatively little research has been done on designing fault-tolerant reconfigurable fine-grained systems like FPGAs which are complete (i.e. including error recovery). In case of a fault occurrence the correct operation of the affected module must be restored and/or the current state of the circuit coherently re-established. The proposed system shall serve as a core for future embedded server with an ability to perform error detection and correction.Keywords

This paper uses the wavelet, Contourlet transform and the two dimensional Principle Component Analysis (2DPCA) for image denoising. The simulation results is carried out to demonstrate the performance of proposed techniques and the result shows that 2DPCA is superior over contourlet and wavelet transform in maintaining high peak signal -to-noise -ratio. The denoising algorithm is validated by numerical experiments on different standard images and roughness images. Numerical result shows that the proposed method can obtain higher PSNR and less visual artifacts compared with other methods. Also, Contourlet can provide a much more detailed representation for natural images with abundant textural information than Wavelets. The improved two dimensional PCA (2DPCA) extended the traditional principal component analysis theory to the two dimensional situation, and proved to be especially efficient in the analysis of images.Keywords

Level set-contour region based segmentation methods are the numerical techniques for tracking interfaces and shapes. They have been successfully used in image segmentation. It consists of an internal energy term that penalizes deviations of the level set function from a signed distance function, and an external energy term that drives the motion of the zero level set toward the desired image feature. The energy to be re-formulated in a local way. It considers local rather than global image statistics and evolves a contour based on local information. Localized contours are capable of segmenting objects with heterogeneous feature profiles that would be difficult to capture correctly using a standard global method.Keywords

In this work, a method to reduce electroencephalogram (EEG) artifacts from Visual-Evoked Potentials (VEP) in brain-computer interface (BCIs) design is presented. For the test composite signal the frequency ranges corresponding to stimulus-related VEP components were located using cyclo stationary (CS) analysis based algorithm. The resulting cyclic frequency spectrum provides VEP frequency band detection. Using this identified frequency ranges, low pass or band pass filtering is employed for EEG artifacts reduction. The proposed Statistical Coefficient Selection (SCS) and wavelet-based method called Wavelet Denoising Algorithm (WDA) are used to distinguish VEP components and EEG artifacts. The proposed scheme exhibits satisfactory results with various datasetsKeywords

To compare the performance of two speech coders, it is necessary to have some indicator of the intelligibility and quality of the speech produced by each coder. The term intelligibility usually refers to whether the output speech is easily understandable, while the term quality is an indicator of how natural the speech sounds. It is possible for a coder to produce highly intelligible speech that is low quality in that the speech may sound very machine-like and the speaker is not identifiable. On the other hand, it is unlikely that unintelligible speech would be called high quality, but there are situations in which perceptually pleasing speech does not have high intelligibility. We briefly discuss here the most common measures of intelligibility and quality used in formal tests of speech coders.Keywords

A new methodology in partitioning of hardware/software that helps to complete the tasks in time without missing the deadlines is proposed. The scheme is endowed with a sensible and swift hardware elucidation to the quandary of irregularity between data and metadata in multiprocessor systems when information flow tracking functionality is decoupled from the main core. This resolution influences cache lucidity mechanisms to witness interleaving of memory operations from application threads and repeat the same order on metadata processors to preserve uniformity thereby permit approved implementation of dynamic scrutiny on multithreaded programs. Maintains reliability even when a graphics code is moved from user mode to kernel mode. Thus, there is no degradation violation in the proposed scheme. Also, a multistage process approach is used in the present work to allocate and there is no need to alter the applications that are run subsystems are created and allocated dynamically such that any user mode process are offered to run programs across different operating system.

Temperature control in plastic extrusion plant is a crucial process. The first order temperature control system comprises of coupling effects, long delay time and large time constants. The model is controlled with three unique control techniques. The first technique is PID control;the second is fuzzy logic control while the third control technique is Adaptive Neuro Fuzzy Control. ANFIS controller is most powerful approach to retrieve the adaptiveness in the case of nonlinear system. While designing a controller it must be first tuned to the system. The tuning synchronizes the controller to the controlled variable and make the process to kept at its desired operating condition. Relatively ANFIS controller gives improved performance than PID & FUZZY controller as shown by simulink of Matlab.Keywords

A field experiment was carried out to study the effect of sulphur, zinc and iron nutrition on growth, yield and nutrient uptake by safflower on Vertisol at the Main Agricultural Research Station, University of Agricultural Sciences, Dharwad, during Rabi season 2002-03. The results indicated that application of 30 kg S per ha showed superior growth parameters like plant height, number of leaves per plant, number of branches per plant and dry matter per plant, yield components like number of capsules, seed weight per head, 1000-seed weight and nutrient uptake of N, P, K, S, Zn and Fe as compared to other treatments. Combinations of sulphur along with micronutrients had significant influenced on the growth, yield and nutrient uptake by safflower. The treatment receiving 30 kg S per ha+Fe+Zn foliar recorded the highest growth, yield and nutrient uptake as compared to 30 kg S per ha, 20 kg S per ha+Fe, Zn foliar, 10 kg S per ha+Fe+Zn foliar spray and control.Keywords

Suppose {Xn, n ∈ Z+) - see below for the notations used - is a sequence of random variables (rv's) such that, for every t > 0 and for ψ given by (1.1) below,
ψ(X(nt);αn;βn)->Y(t),
where Y\l) (in particular) is (assumed) nondegenerate. Then it is shown that, for some positive functions α and β on (0,∞) and for every t > 0,
Y(t)=ψ(Y(1);α(t),β(t))
Explicit expressions for a and p are derived. As an application, the (Pancheva) class of all possible limit laws for power normalized partial maxima of i.i.d rv's ("the p-max stable laws") is re-derived.

In this article, we discuss the potential of airborne hyperspectral data in mapping host rocks of mineral deposits and surface signatures of mineralization using AVIRIS-NG data of a few important geological provinces in India. We present the initial results from the study sites covering parts of northwest India, as well as the Sittampundi Layered Complex (SLC) of Tamil Nadu and the Wajrakarur Kimberlite Field (WKF) of Andhra Pradesh from southern India. Modified spectral summary parameters, originally designed for MRO-CRISM data analysis, have been implemented on AVIRIS-NG mosaic of Jahazpur, Rajasthan for the automatic detection of phyllosilicates, carbonates and Fe–Mg-silicates. Spectral analysis over Ambaji and the surrounding areas indicates the presence of calcite across much of the study area with kaolinite occurring as well in the north and east of the study area. The deepest absorption features at around 2.20 and 2.32 μm and integrated band depth were used to identify and map the spatial distribution of phyllosilicates and carbonates. Suitable thresholds of band depths were applied to map prospective zones for marble exploration. The data over SLC showed potential of AVIRIS-NG hyperspectral data in detecting mafic cumulates and chromitites. We also have demonstrated the potential of AVIRIS-NG data in detecting kimberlite pipe exposures in parts of WKF.Keywords
