The paper explores the hybrid of SVM and system of Artificial Neural Network as the finest binary classification system for calculating the diabetic nature of people in comparison to Support Vector Machine (SVM). In this research, the sets of all the parameters describing the diabetic nature of a person are taken from the laboratories. This approach is chosen so that a better learning method can be used for various problems. The testing results were found to be in accordance with the accepted results that resemble with the direct diagnosis of a physician. The results of this research shows that this hybrid SVM and Artificial Neural Network (ANN) model is more precise than the SVM model. These results of the hybrid SVM and ANN model suggest that it is very effective for the classification of Diabetic and Non Diabetic nature of a person. This paper highlights the concept of Support Vector Machines and its integration with Artificial Neural Network, the two key characteristics with one being the generalization theory of the SVM model that best describes how to select a hypothesis and functions given by Kernel that introduces the idea of non-linearity without the inclusion of the actual algorithm.

A software practice like code reusability in the successive upgradations of the particular software is increasing vigorously. The software is upgraded when the new requirements of the customers explored in the market, thus it includes some of its own newly defined functionalities and some existing functionalities. However, the upgradation/version also includes the vulnerabilities which are generated either due to the effect of new features or the shared ones that were not resolved while testing. In operational phase, the vulnerabilities are discovered through the users who may adopt multiple versions of the software or have used only the single version. We have observed that the developers face many problems while predicting the multi upgradation vulnerabilities as some proportion of the vulnerabilities and the users of the successive versions are found to be similar. In this research work, we proposed a mathematical model that highlights the prediction of user-dependent vulnerabilities in a Multi-Upgradation software system. The model emphasizes on the impact of the shared code on the vulnerability's frequency rate and user's growth rate. A numerical is illustrated to validate the model capabilities with the help of real life data set.

Historical documents are valuable source of information but commonly suffer from degradation problem. The task is to keep these documents alive to preserve the important information and the heritage of a country. The main aim of this paper is to transform them into digital form and enhance the quality and visualization of the historical images. Image processing techniques such as noise filtering, histogram equalization and power law transformation have been used to result in better representation of images. To evaluate the quality of resultant image, two performance assessment parameters; entropy and standard deviation, have been used. Matlab results indicate the efficacy of proposed technique to remove the background noise and thereby improving the quality of historical degraded images. The proposed method is much easier and may help to archive the documents in digital images with improved quality.

At the present time using the standard (generalized) voltage static load characteristics which can differ from actual considerably is provided in software packages for calculations of the steady-state mode and steady-state stability (in the absence of exact data). Absence of the metering or the incorrect metering of the actual voltage static load characteristic, and also using the standard (generalized) static load characteristics could lead to considerable errors and the incorrect final results while making calculations. The definition experience of actual voltage static load characteristics in different ways made by authors is given in this paper: making tests in situ in electric power systems by allocation of energy area load or separately taken electric power substation to the isolated electric supply, load allocation of the power supply from the power plant generator; registration data using of crash conditions of the electric power system. Such test of actual voltage static load characteristics definition in electric system of Russia it is reduced by authors in making tests in situ technique. Error estimation which can appear in calculations of steady-state modes with the absence of the voltage actual load characteristics is executed.

Intra-ocular lenses are used to replace the natural lenses in eyes when it grows cloudy, a condition known as cataract which is typically observed among elderly people. Lens that is to be placed inside one's eye necessitates the use of precision tools and high quality materials to prevent any damage to one's eyesight. This in turn, requires the development of technologies which aid in production of lenses of superior quality and quality inspection. Currently, most companies perform manual inspection of lenses which is a laborious process and prone to human errors. This paper would postulate an algorithm for the implementation in an automated intra-ocular lens defect detection and quality assessment system. This would reduce time and cost of labor significantly leading to better segregation of lenses and increase in output quality.

Traditionally spectrum sensing approaches do not take the historical traffic data into account. In such approaches, equal amount of time is allocated for spectrum sensing of the sub-bands in the band of interest. In this research paper, we formulate the problem of time optimal spectrum sensing taking the historical data into account. We solve the problem in practically interesting special cases. Effectively interesting integer programming problems are solved. In that effort it is shown that the variance of discrete random variable constitutes a quadratic form associated with a laplacian like matrix. Using this result, time optimal spectrum sensing is formulated as a multi-linear objective function optimization problem.

In present competitive market place, industries are more focused around the standard test practices & procedures which help in identification of the weak links in the design & help improve robustness of the products. In the similar context most of the electronics product industries have adopted HALT (Highly Accelerated Life Testing) as a standard test practices to uncover the weak links & latent defects in the electronics board against temperature, vibration & the combined (temperature & vibration) stresses. The HALT guidelines accepted by most of the industries emphasizes on only the temperature and vibration step stress test profiles which may not relate to the ASSP (Application Specific Stress Profile) of all the products. This research help in inclusion of ASSP in conventional HALT which helps conduct HALT in more effective way. In this paper, a case study on DCD (Dimming Control Device) has been presented to showcase how an addition of ASSP to conventional HALT step stress test profile has strengthened the design by uncovering the latent defects.

In many countries of the world, distributed generation takes on greater and greater importance. The share of energy generation by distributed generation facilities in the countries of the European Union averages about 20%, incl. in Denmark — 47%, Germany — 45% of all generated energy. This is due to the fact that when integrating distributed generation facilities, additional systemic effects are reached along with generation of electric and heat energy: reduction in losses during energy transmission, increase in reliability of energy supply to consumers, reduction in required investments for development of distribution networks and other effects. The purpose of this article is to determine methods of assessment of systemic effects from integration of distributed generation facilities. The probabilistic economic and mathematical model of reliability of the regional energy system and method of comparative analysis were used for achievement of this purpose. As a result of the carried-out work, methods of assessment of systemic effects were developed and assessed on the example of potential integration of distributed generation facilities into the regional energy system of the Leningrad region of Russia. The potential distributed generation facilities were boiler plants that can be reconstructed into cogeneration facilities. Systemic effects were determined when integrating distributed generation facilities: reduction in capital investments for development of distribution networks of the regional energy system of the Leningrad Region makes 37–90$/kW, reduction in operational costs for energy transmission — 3$/kW, reduction in losses from undersupply of energy at consumers — 110$/kW. Such assessment of systemic effects from integration of distributed generation facilities may be used in a comprehensive planning of development of regional energy systems in order to improve the efficiency of their operation.

A single layer proximity fed circularly polarized microstrip antenna for dual band applications is presented. A cross shaped slot with asymmetric dimensions is present on the radiating element with an X-shaped strip embedded along the cross slot for feeding the square patch. In the proposed design, two pairs of circular slots are loaded orthogonally on the square patch. The suggested circular slots excite two orthogonal waves equal in amplitude and with 90 degree phase difference for circular polarization without cutting any portion of the patch. The antenna dimensions are optimized considering the effect of different radius of the circular slot. The antenna dimension is 80 mm × 80 mm × 1.6 mm. The designed antenna has −10 dB reflection coefficient bandwidths of 3.2–3.9 GHz in the first band and 4.9 GHz to 5.6 GHz in the upper second band. The axial ratio bandwidth lies from 3.3–3.4 GHz in the lower band and an upper band from 5.4 GHz to 5.6 GHz.

Software reliability growth models (SRGMs) proposed on the foundations of Non-Homogenous Poisson Process (NHPP) have been the most accepted way to analyze reliability growth of a software since 1970's. Henceforth, Literature witnesses the evolution of SRGMs in terms of different assumptions, parameters, performance etc. This study is an attempt to model reliability growth phenomenon for Open Source Software (OSS). As the development process followed by OSS significantly differs from proprietary software, traditional software engineering SDLC models can't be followed for its development. OSS development procedure does not incorporate a dedicated testing phase and therefore negligible effort expenditure is done on testing of software prior its release. The volume of volunteer participation in its operational phase thus becomes a significant criterion in the representation of its reliability growth. Also, the impact of sudden changes in fault detection process (change-point) due to several reasons like variations in fault density, irregular team size, volunteer expertise etc is captured in proposed SRGM. This paper suggests a reliability model based on user growth with the concept of change point to better cater the heterogeneity in software failure process. Failure data of GNOME 2.0 is used in this paper reliability growth analysis. Unknown parameters are estimated using Least Square Estimation regression technique. Performance inspection of proposed SRGM is carried out using goodness-of-fit criteria like Mean square error (MSE), Coefficient of Determination (R2), Predictive Ratio Risk (PRR), and Predictive Power (PP). The study recommends that introduction of the change-point in SRGM improves prediction capability of the model and hence establishes an evidence of its applicability.
