A New Approach to Speed-up the Fractal Image Compression Process with Desired Image Quality

Now a days saving the bandwidth on the Internet is a major issue. In Indian scenario the issue is more relevant because we don’t have very high speed lines to handle the huge traffic. In this era we cannot think of the messages without still images and videos. Videos are considered as the sequences of frames or images. Therefore image is the basic unit of compression in multimedia messages. Images can be broadly classified into two classes. One that cannot tolerate any loss like technical drawings, geometric shapes or medical images. Another class of image can tolerate loss upto certain extent until the loss is noticible by human eye. The natural images lie in the later class. This paper focuses on lossy compression of natural images with fractal approach. The objective of the paper is two fold. Firstly the search area is minimized by consturcting subsets of domain and range block sets and restricting the search in that particular subset only, this results in fast search. Another objective is to obtain desired closeness between range and domain blocks by adjusting the closeness parameter defined in the paper. To achieve the lossy compression with fractals the image is partitioned into many square shaped blocks called domain blocks. After that the further partition into smaller blocks called range blocks is carried out. For each range block the best matched domain block is searched in the entire image. The performance of the matching procedure is examined by the fact that how closely the matching is done.

Influence of the Oxidant on the Chemical and Field-Effect Passivation of Si by ALD Al2O3

Differences in Si surface passivation by aluminum oxide (Al2O3) films synthesized using H2O and O-3-based thermal atomic layer deposition (ALD) and plasma ALD have been revealed. A low interface defect density of D-it = similar to 1011 eV(-1) cm(-2) was obtained after annealing, independent of the oxidant. This low D-it was found to be vital for the passivation performance. Field-effect passivation was less prominent for H2O-based ALD Al2O3 before and after annealing, whereas for as-deposited ALD films with an O-2 plasma or O-3 as the oxidants, the field-effect passivation was impaired by a very high Dit.

Radioactive Seed Localization for Nonpalpable Breast Lesions in a Community Hospital Setting

Purpose: To compare the positive margin rates for women with nonpalpable breast tumors whom had wire localization compared to radioactive seed localization in a small community hospital. Introduction: Wire localized (WL) breast biopsies have been performed on patients with nonpalpable breast lesions for many years. Radioactive seed localization (RSL) offers advantages of patient comfort and scheduling convenience. There is an extensive literature from large centers regarding the RSL technique. Little is known whether physicians performing these procedures in smaller community hospitals can achieve comparable negative margin rates as those performed with wire localization. Methods: The thirty-six patients who underwent wire localized breast conserving surgery between September 18, 2013 and December 10, 2014, were compared to the 48 radioactive seed localization patients resected between February 12, 2014 and December 18, 2014. The primary objective was to determine if the introduction of the radioactive seed localization technique significantly changed the positive margin rate. Results: Two of 36 wire localized breast biopsied patients had positive margins, compared to 5 of 48 radioactive seed localization patients, a difference which is not statistically different. The specimen weight was larger for the patients treated with the RSL technique. There was a trend toward a higher positive margin rate with older patients. Conclusion: The positive margin rate was similar between the wire localized and radioactive seed localized patients, and comparable to those in the published literature.
Cyber Security : Protection of Human Rights

Presently, it is basic to share data publically on the web. There are numerous social sites which are utilizing person's information to show publically. Although each site clarifies their privacy policies however everybody doesn't know from these points of interest. Thus, there are numerous breaks to person's data. At the point when data is access by unapproved people utilizing Computer as well as Internet then it is a crime known as a cyber crime. It is our right to keep the information private and if someone is rupturing the security of other without approval then it resembles violations of human rights. This article gives information about cyber crime, privacy, right to privacy, and protection of this private data of individuals by National Cyber Security Policy.
Analysing voting behavior of the Lithuanian parliament using cluster analysis and multidimensional scaling : technical aspects

Rational models of electoral behavior emphasize the need of sufficient information for voters to make their decisions. Monitoring the behavior of a single politician is not easy to implement, not to mention of the whole parliament, since for the latter one must apply statistical methods designed for the analysis of large amounts of information. In this paper we propose methods and techniques for the analysis of voting behavior of the Lithuanian Parliament (Seimas) that allow for clearer identification and recognition of voting patterns of the Seimas. Votes of the last sessions of the 2008-2012 term of the Seimas (pre-election period) are analyzed employing cluster analysis. Also, multidimensional scaling is used to visualize the generated results. Results obtained using different vote coding methods and clustering techniques are compared in the paper, too.
Performance comparison of axial-flux-modulated motor with two pole-slot combinations

Axial-flux-modulated motors (AFMMs) with two pole-slot combinations are presented and analyzed quantitatively. They all have new topology structures, and their design rules differ from those of the traditional machine. The concentrated stator windings are designed to reduce the end length and copper losses; therefore, the efficiency of the motors can be improved. Special iron segments in the air-gap are used to modulate the magnetic field. The two proposed AFMMs have 36 stator slots and 30 stator slots, respectively, and the pole-slot combinations are 6 poles for 36 slots and 4 poles for 30 slots. This paper focuses on the comparative performance analysis of the two proposed AFMMs by using the 3D time-stepping finite element method. The flux linkage, air-gap flux density, electromotive force waveforms, output torque, core losses, and efficiency of the two proposed AFMMs have been investigated.
Trends in Arctic sea ice extent from CMIP5, CMIP3 and observations

The rapid retreat and thinning of the Arctic sea ice cover over the past several decades is one of the most striking manifestations of global climate change. Previous research revealed that the observed downward trend in September ice extent exceeded simulated trends from most models participating in the World Climate Research Programme Coupled Model Intercomparison Project Phase 3 (CMIP3). We show here that as a group, simulated trends from the models contributing to CMIP5 are more consistent with observations over the satellite era (1979–2011). Trends from most ensemble members and models nevertheless remain smaller than the observed value. Pointing to strong impacts of internal climate variability, 16% of the ensemble member trends over the satellite era are statistically indistinguishable from zero. Results from the CMIP5 models do not appear to have appreciably reduced uncertainty as to when a seasonally ice‐free Arctic Ocean will be realized.
Approaches in biotechnological applications of natural polymers

Natural polymers, such as gums and mucilage, are biocompatible, cheap, easily available and non-toxic materials of native origin. These polymers are increasingly preferred over synthetic materials for industrial applications due to their intrinsic properties, as well as they are considered alternative sources of raw materials since they present characteristics of sustainability, biodegradability and biosafety. As definition, gums and mucilages are polysaccharides or complex carbohydrates consisting of one or more monosaccharides or their derivatives linked in bewildering variety of linkages and structures. Natural gums are considered polysaccharides naturally occurring in varieties of plant seeds and exudates, tree or shrub exudates, seaweed extracts, fungi, bacteria, and animal sources. Water-soluble gums, also known as hydrocolloids, are considered exudates and are pathological products; therefore, they do not form a part of cell wall. On the other hand, mucilages are part of cell and physiological products. It is important to highlight that gums represent the largest amounts of polymer materials derived from plants. Gums have enormously large and broad applications in both food and non-food industries, being commonly used as thickening, binding, emulsifying, suspending, stabilizing agents and matrices for drug release in pharmaceutical and cosmetic industries. In the food industry, their gelling properties and the ability to mold edible films and coatings are extensively studied. The use of gums depends on the intrinsic properties that they provide, often at costs below those of synthetic polymers. For upgrading the value of gums, they are being processed into various forms, including the most recent nanomaterials, for various biotechnological applications. Thus, the main natural polymers including galactomannans, cellulose, chitin, agar, carrageenan, alginate, cashew gum, pectin and starch, in addition to the current researches about them are reviewed in this article.
Thinking of the blue ocean - strategy beyond the competition

Throughout history, the competition had been the dominant strategy of different businesses that based on, the companies were trying to gain a greater share of the market. It should be noted, however, that the fierce competition causing it to be an oversupply. It should also be noted, that always gain a greater share of the market, and it does not mean increased profits. Hence, Researchers of blue ocean strategy convinced that the only way to win the competition is stop trying to win the competition. Instead of entering into a bloody competition of the Red Ocean, have to enter the infinite market space of Blue Ocean and try to create new demands. Blue Ocean market is a market that is still not clear the rules of the game and there are many opportunities for growth and profitability. In a word, blue ocean thinking argues that instead of getting a share of more than cake, we should seek to enlarge the cake. On the other hand, unfortunately, widespread negative effects of the global recession, in our country, also, is quite evident. Therefore, to solve the problems facing organizations in different areas of management, this study was conducted. This paper introduces the blue ocean strategy, then, provides the positive effects of using it. This article is a kind of applied research and the method of doing it, there is a description and analysis and library studies.
Evaluating the selectivity of registered fungicides for soybean against Trichogramma pretiosum Riley, 1879(Hymenoptera: Trichogrammatidae).

The aim of this study was to evaluate the effects of fungicides registered for soybean on the parasitoid Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae). Bioassays wereconducted in laboratory exposing adult insects to dried residues of fungicides, using the methodology proposed by the International Organization for Biological and Integrated Control of Noxious Animals and Plants (IOBC). The experimental design was completely randomized with four replications per treatment. The parameter used for classification of fungicides was based on the reduced parasitism (RP) evidenced by the number of parasitized eggs per female in the control treatment. Based on these results, we found that fungicides are classified in different classes of selectivity to adults of T. pretiosum regarding the tested fungicides. The fungicides cyproconazole, epoxyconazole + kresoxim-methyl, metconazole, thiophanatemethyl (CS), pyraclostrobin, difenoconazole, were classified as harmless (Class 1); carbendazim, carbendazim + thiram, tetraconazole, tetraconazole+ azoxystrobin, epoxyconazol + pyraclostrobin, tebuconazole, prothioconazole + trifloxystrobin, tebuconazole + trifloxystrobin, azoxystrobin, azoxystrobin + cyproconazole, and thiophanate methyl (WG) were slightly harmful (Class 2); flutriafol, thiophanate methyl (WP), epoxyconazole + pyraclostrobin, and cyproconazole+ trifloxystrobin were moderately harmful (Class 3); and Kumulus DF was harmful (Class 4) to the adult parasitoids. Keywords: Chemical control, integrated pest management (IPM), parasitoid eggs, pesticide, International Organization for biological and integrated control of noxious animals and plants (IOBC) methodology, soybean.
Bars in dark-matter-dominated dwarf galaxy discs.

We study the shape and kinematics of simulated dwarf galaxy discs in the APOSTLE suite of Lambda cold dark matter (Lambda CDM) cosmological hydrodynamical simulations. We find that a large fraction of these gas-rich, star-forming discs show weak bars in their stellar component, despite being dark-matter-dominated systems. The bar pattern shape and orientation reflect the ellipticity of the dark matter potential, and its rotation is locked to the slow figure rotation of the triaxial dark halo. The bar-like nature of the potential induces non-circular motions in the gas component, including strong bisymmetric flows that can be readily seen as m = 3 harmonic perturbations in the HI line-of-sight velocity fields. Similar bisymmetric flows are seen in many galaxies of The HI Nearby Galaxy Survey (THINGS) and Local Irregulars That Trace Luminosity Extremes THINGS (LITTLE THINGS), although on average their amplitudes are a factor of similar to 2 weaker than in our simulated discs. Our results indicate that bar-like patterns may arise even when baryons are not dominant, and that they are common enough to warrant careful consideration when analysing the gas kinematics of dwarf galaxy discs.
Preparation, Physico-Chemical Characterization and Pharmacodynamics of Ceftriaxone Loaded BSA Nanoparticles

The aim of the present study was to develop and characterize ceftriaxone loaded BSA nanoparticles. The nanoparticles were prepared by desolvation method. Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and fourier transform infrared (FT-IR) characterization of the synthesized nanoparticles was done. SEM and TEM revealed that the nanoparticles had a smooth and spherical surface and FT-IR revealed that there was no interaction between the drug and the polymer. Encapsulation efficacy of nanoparticles was 44.8%. The mean particle size of BSA obtained was 149.46 ± 1.05 nm, PDI was 0.09 and the zeta potential was -28 mV. In vitro drug release at pH 7.4 was found to be 85.8% at 12 h time period. Various mathematical models were used and the values nearest to R2 were evaluated. Model fitting revealed that it followed the Higuchi and Korsmeyer Peppas Model. The values of R were higher for Higuchi and Korsmeyers peppas model. Pharmacodynamic studies were done, for S. aureus the results of MIC and MBC of Drug were 2.51 μg and 3 μg. The results of MIC and MBC of sample were 1.51 μg and 2.1 μg and for E. coli the results of MIC and MBC of Drug were 0.05 μg and 0.08 μg. The results of MIC and MBC of sample were 0.05 μg and 0.05 μg.
Some rankings for the Athens Olympic Games using DEA models with a constant input

There is no official method to establish a final ranking for the Olympic games. The usual ranking is based on the Lexicographic Multicriteria Method, the main drawback of which is to overvalue gold medals. Furthermore it does not take in account that the various sports may be of different importance. This work proposes a ranking model to eliminate those drawbacks. First we use a modified cross evaluation DEA (Data Envelopment Analysis) model with weighted restrictions for each sport. The outputs are the number of gold, silver and bronze medals and the input is a unitary constant for all countries. After obtaining a rank for each and every sport we build a general ranking using a weighted sum. The weights are calculated taking in account the number of countries that participated in each sport. We use our model with the results of the Athens Olympic Games.
Conservative adaptation of workflow

Business processes and, tberefore, workflow models are often adapted. Adaptations can be caused eitber by procedural changes, affecting all future cases or on an ad-hoc basis for individual cases. Eitber way, cases witb similar but different definitions will coexist in an organization. One can conserve tbe Similarity of such cases by considering tbem as extensions or reductions of one and tbe same common ancestor. The extension/reduction concept is based on selectively blocking and skipping tasks, combined witb delay bisimilarity. Views can be defined and used for monitoring tbe flow of cases on a high level. An example case study is given, using Petri Nets as tbe modeling framework.
The Performance Comparison of LCMV and LCMN to Signals, Interference and Noise

To achieve the SDMA scheme of a smart antenna system, we may introduce the LCMV algorithm to set direction constraints to preserve the desired signals as well as to suppress interference simultaneously. To apply LCMV, however, we will encounter the heavy computing load as well as the unknown covariance matrix problems which make the implementation of a LCMV-based smart antenna system especially challenging. In this paper a simplified algorithm LCMN, with much less computing load, is introduced as the substitute of LCMV algorithm for smart antenna system. The performance of these two algorithms is compared. We found that LCMV is adaptive and outperform LCMN in interference suppression, while LCMN is non-adaptive and is less susceptible to noise. Moreover LCMN can achieve the same performance as that of LCMV does when the columns of constraint matrix can span signal subspace.
Role of Change Management in Information System Implementations: Case of Custom Designed Information System Implementations in Sri Lanka

Utilising information systems (IS) projects in business organizations is extremely high. A high failure rate of IS implementations have also been reported world-wide. Previous literature emphasizes poor Change Management (CM) as one of the major factors behind this high failure rate. This research deals with understanding the CM perspective of IS implementation projects with the overall aim of improving their success rate. Though sufficient research has been undertaken with respect to implementations such as Enterprise Resource Planning (ERP), studies on custom designed IS implementations are quite limited. In particular, such research has not been carried out in developing countries like Sri Lanka. Hence, this research aims at gaining in-depth and comprehensive understanding of change processes associated with custom designed IS implementations in Sri Lankan business organisations. The case study method has been used as the principle research approach of this study. A new framework for implementation of custom designed IS projects focusing on best practices are developed and validated having mapped out six different cases with four theoretical models. This framework highlights certain CM related factors such as top management support and change leader have a major influence on the success rate of IS implementations. This framework can be productively used by IS practitioners in their IS project implementations and by researchers who are interested in this area as a frame of reference for future studies.
