An Effective Algorithm to Generate Positive and Negative Association Rules

: Recently, mining negative association rules has received some attention and been proved to be useful in real world. This paper presents an efficient algorithm (PNAR) for mining both positive and negative association rules in databases. The algorithm extends traditional association rules to include negative association rules. When mining negative association rules, we use same minimum support threshold to mine frequent negative itemsets. With a Yule’s Correlation Coefficient measure and pruning strategies, the algorithm can find all valid association rules quickly and overcome some limitations of the previous mining methods. The experimental results demonstrate its effectiveness and efficiency.
A SURF-COLOR MOMENTS FOR IMAGES RETRIEVAL BASED ON BAG-OF-FEATURES

: An important research issue in multimedia databases is the retrieval of similar objects. Most of the Content-Based Image Retrieval (CBIR) system uses the low-level features such as color, texture and shape to extract the features from the images. In Recent years the Interest points are used to extract the most similar images with different view point and different transformations. SURF is fast and robust interest points detector/descriptor which is used in many computer vision applications. In the state-of-the-art the SURF is combined with Color Moments to improve the performance of the system. In this paper, we propose one presentation (LOWE 2004) to improving image search based on the color and shape descriptors. The representation is obtained by the quantification of the SURF (Herbert and all 2008) combined with the color moments (Stricker and all 1995), and so called Bag-of-Features and Colors (BOFC). Experiments show that our descriptor BOFC provides better results than a standard Bag of Visual Words approach based on SURF (BOF).
Effect of chemical cross-linking agents on dentin bonding

Georgia Macedo, DDS: Effect of Chemical Cross-linking Agents on Dentin Bonding. This study investigated the effects of Glutaraldehyde (GA) and Grape Seed Extract (GSE)-induced cross-linking on: 1. the stability of dentin collagen, and 2. dentin bond strengths of sound and caries-affected dentin. Our results demonstrated that the treatments of dentin collagen with GA and GSE significantly increase dentin collagen stability (resistance to collagenase degradation) in sound and caries affected dentin, likely via distinct mechanisms. In addition, the application of chemical cross-linking agents (GA and GSE) to etched dentin prior to bonding procedures significantly enhances dentin bond strengths for sound and caries-affected dentin. Gustavo and Greice all of whom had a very positive influence on my graduate education. Finally and most importantly, I would like to thank especially my parents-Silvio and Sandra, my brothers-Daniel and Silvio Neto, my grandparents, and uncle Arnie and aunt Silvia, whose unconditional love and encouragement made my studies possible. iv DEDICATION To my parents, Dr. Silvio Macedo Jr. and Mrs. Sandra Macedo for their guidance, support, extraordinary courage and unconditional love. Thank you, always.
Prevalence of Overweight and Obesity Among Staff of a Tertiary Institution in Kumasi, Ghana

The study aimed at investigating the prevalence and gender distribution of overweight and obesity among staff at the Kwame Nkrumah University of Science and Technology (KNUST). In a cross-sectional study using simple random sampling, 250 staff members of KNUST aged 25 to 60 years were selected. Height (m) and weight (kg) were measured using standard procedures and body mass index (BMI) was calculated. Overweight and obesity were determined using WHO classification. The Statistical Package for Social Scientists version 20.0 was used to analyze data. Descriptive statistics and independent sample t-test were employed. The prevalence of overweight was 34.4% and that of obesity was 6.0% among the staff of KNUST. The difference in BMI between males and females was not significant (p > 0.05), but males were significantly taller and heavier than females (p < 0.05). A significant number of the subjects were overweight and obese and may be at risk of associated disease conditions.
A Comparative analysis of Sizing and Siting of Distributed Generation Using Evolutionary Techniques

Distributed Generation (DG) resources have a lot of concentration in recent times due to its optimistic impact on power system. most favorable planning of distribution system with distributed generation resources is not only concerned with the sizing of distributed generators but gives due weightage to the placement of generators as well. The installation of DG at optimum location boosts the performance of distribution system as well as presents a cost effective solution thus giving a new dimension to distribution system planning. The positive impacts of optimal distributed generator placement are reflected in terms of improved distribution system reliability, reduced customer interruption costs, reduction in losses and improvement in voltage profile as well as power quality at the consumer terminal. In order to enable electric utilities to obtain maximum benefits, the placement problem calls for state of art optimization techniques capable of handling multiple objective simultaneously in order to present the best feasible solution. This paper aims at providing an overview of several methodologies which have been adopted for finding out optimal location of distributed Generator in distribution system in order to maximize benefits.
A Hybrid Approach to Compress Still Images using Wavelets and Vector Quantization

-This paper presents a hybrid technique for compression using Wavelet and Vector Quantization (VQ). Wavelet is a technique for representing the image into various degrees of resolution. The input image of size 256 *256 pixels is divided into 4 sub-bands named LL, HL, LH, HH by applying Discrete Wavelet Transform. Vector Quantization is then applied for the lower sub band (LL). The size of lower sub-band is 128*128 pixels. VQ is a lossy image compression technique used to have improved coding efficiency. In the proposed study, the different types of wavelets such as Haar Wavelet, Coiflet Wavelet, Symlet Wavelet, Daubechies Wavelet and Bioorthogonal Wavelet are applied to the input images and the respective lower bands are then subjected to Vector Quantization in the Encoding process. The compressed image is then transmitted or stored in the form of Codebook and the Index Map, which are the outcomes of VQ. In the decoding phase, an image of size 128 x 128 pixels is reconstructed from the stored/transmitted Codebook and Index map. The reconstructed image is then subjected to Inverse DWT to get an output image of size 256 x 256 pixels. Standard images such as Lena, Baboon, Boats, Bridge and Cameraman are used to test the performance of the proposed method. With all the wavelets, the proposed technique leads to better compression ratio without losing the visual effect.
PLC Based Control System for Brix Measurement

This paper presents utilization of Programmable Control System (PLC) for sugar factory brix measurement. Brix is dissolved amount of sucrose crystal to clear syrup named after German mathematician and engineer Adolf Brix (symbol °Bx). Sugar industry use batch pans for boiling of clear syrup to form the sugar crystals. This pure crystal can only be developing in certain confined pan parameters. Pressure, temperature, vacuum and level are the main parameters of a pan system. One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by mass. PLC is a current trend in control system. In sugar industry PLC can be used for controlling parameter of the batch pan. PLC based control system can improve the results of this non-linear multi input multi output system. Keywords— PLC, CONTROL SYSTEM, BRIX, CONDUCTIVITY, CRYSTALLIZER.
Effect of Pesticides used in Tomato Fields of Iran on the Egg Parasitoid Trichogramma brassicae (Hymenoptera: Trichogrammatidae) under Laboratory Conditions

Toxicity of selected insecticides and fungicides on different developmental stages of the egg parasitoid Trichogramma brassicae Bezdenko (Hymenoptera: Trichogrammatidae), were investigated in the laboratory. Persistent toxicity of selected pesticides on the adult stage of parasitoid was also determined. The insecticides cypermethrin, chlorpyrifos, imidacloprid, and indoxacarb had a significant adverse effect on the immature stages of the parasitoid. Among the tested fungicide, benomyl appear to be toxic to the pupal stage of T. brassiace. However, the other tested fungicide, mancozeb, chlorotalonil, and iprodione + carbendazim did not affect the preimaginal stages of the parasitoid. The results of the tests revealed that all the tested fungicides caused high mortality to adult wasps. The results of the persistency test showed that all pesticides were “moderately persistent” except chlorpyrifos that was classified as “persistent”. The implications of these results for the integration of biological and chemical control methods are discussed.
Solar Irradiance Measurement Using Neuro Fuzzy Network

— Solar irradiance is a key parameter for MPPT in pv power plants.The operating point at which a pv array deliver its maximum power ,changes as a function of irradiance and temperature.If we sensed the both solar irradiance and temperature values we can easily compute maximum power point,moreover forcing pv array to operate at that point to increase effiency . Temperature sensing is easy, however, measuring solar irradiance is difficult because irradiance sensors are expensive and difficult to calibrate.To overcome those difficulties we go for measuring irradiance based on neuro fuzzy networks . The proposed sensor is implemented through a photovoltaic cell, a temperature sensor, and a low-cost microcontroller. The use of a microcontroller allows for easy calibration, updates, and enhancement by simply adding code libraries. Furthermore, it can be interfaced via standard communication means with other control devices, integrated into control schemes, and remote-controlled through its embedded web server.
Int. J. Biosci

The endomycorrhizal fungus Piriformospora indica is well known for inducing disease resistance, elevation of salt tolerance and increasing biomass in symbiotic plants. The aim of the present study is to evaluate the effect of P. indica on tomato (Lycopersicon esculentum Mill) under lead stress (Concentrations of 1 and 2 mM Pb (NO3)‌2). Lead (Pb) is not an essential nutrient for plants and is known as a hazardous pollutant in the environment which originates from various sources. In this study, the effect of lead toxicity and P. indica on antioxidant enzyme activities in both mycorrhizal (MR) and non-mycorrhizal (NMR) tomato plants were investigated. The experiment was performed by using six treatments (mycorrhizal and non-mycorrhizal with and without lead stress) and two concentrations of Pb (1and 2 mM Pb (NO3)2 solution) and then antioxidant enzyme activities (CAT, SOD and APX) in roots and stems of plants were determined. The results demonstrated that lead could affect the activity of antioxidant enzymes in treating plants. As well, in most cases, the rates of the enzyme activities were higher in roots than those of stems, but the impact Pb treatment on enzyme activities in P. indica colonized plants was not significant. * Corresponding Author: Nasrin Sartipnia  nsartipnia@yahoo.com International Journal of Biosciences | IJB | ISSN: 2220-6655 (Print) 2222-5234 (Online) http://www.innspub. net Vol. 3, No. 12, p. 55-64, 2013
Edge Detection by Using Canny and Prewitt

—Edge detection is the name for a set of mathematical methods which aim at identifying points in a digital image at which the image brightness changes sharply or more formally, has discontinuities. Edge detection is one of the most important stages in image processing. It enables features such as curves, lines and corners to be extracted for the purpose of image identification. In this paper several masks such as Prewitt and Canny are convolved with various images to extract edge of objects in the images. Comparisons of these edge detectors show that Canny produced the sharpest images and produced the best continuity of the edge lines. Results also showed canny produce sharpest and clear edge then prewitt.
The Effect of Prior Gestational Diabetes on the Shape of the Glucose Response Curve during an Oral Glucose Tolerance Test 3 Years after Delivery

Objective Monophasic glucose response (MGR) during an oral glucose tolerance test (OGTT) and gestational diabetes mellitus (GDM) are predictors of type 2 diabetes mellitus (T2DM). We investigated the association between current MGR and (1) glucose tolerance during a pregnancy 3 years before and (2) current glucose tolerance status. We also sought (3) other determinants of MGR. Research Design and Methods. We conducted a nested case-control study of GDM (n = 47 early GDM, diagnosed between 16 and 20 weeks of gestation; n = 40 late GDM, diagnosed between 24 and 28 weeks of gestation) and matched healthy controls (n = 37, normal glucose tolerance during pregnancy) all free from diabetes at follow-up 3.4 ± 0.6 years after delivery. Glucose tolerance was determined by 2-hour 75 g OGTT. Monophasic and biphasic groups were defined based on serum glucose measurements during OGTT. Results The biphasic group was younger, had lower triglyceride levels and area under the OGTT glucose curve, and was less frequently diagnosed with early GDM (25 vs. 45%, all p < 0.05). Women with a biphasic response also tended to have lower systolic blood pressure (p < 0.1). No differences were found in fasting and 2-hour glucose and insulin levels, or BMI. According to multiple logistic regression, MGR was associated with prior early GDM (OR 2.14, 95% CI 0.92-4.99) and elevated triglyceride levels (OR 2.28, 95% CI 1.03-5.03/log (mmol/l)). Conclusions We found that more severe, early-onset GDM was an independent predictor of monophasic glucose response suggesting that monophasic response may represent an intermediate state between GDM and manifest type 2 diabetes.
Transparent conducting oxide (TCO) materials have greater importance due to variety of applications such as electrochromic devices, solar cells, opto electronic devices etc

Transparent p type Aluminum doped tin oxide(SnO2:Al) thin films with different Al percentage (10,15,20,25 and 30) were fabricated using a low cost simplified spray pyrolysis technique. The optical properties of the deposited films were characterized in order to study its transmittance and to calculate the optical constants such as refractive index (n) and extinction coefficient (k). The calculated refractive indexes of the films with various Al concentrations were in the range of 1.668 to 1.676. The extinction coefficient values shows that the grown films were stronger absorbing medium in the lower wavelength region. The electrical studies confirm that the deposited films are p type and have the carrier concentration of the order of 10 to 10/cm.
Review on Cyclotomic FFT with Radix-2 2 16-Point FFT

In this paper, an optimized implementation of the 16-point Radix-4 FFT algorithm with Cyclotamic Fast Fourier Transform (CFFT) will be presented. Cyclotomic FFT is type of FFT algorithm over finite fields. This algorithm decomposes a DFT into several circular convolutions and then derives the DFT results from the circular convolution. In previous paper, the pipeline architecture has been implemented for radix-𝟐𝟐 𝒌𝒌 FFT. This paper shows trade-off between area and performance. It saves less number of adders with respect to design utilization ratio. Thus, Cyclotomic FFT will help to reduce this trade-off over FFT. In this paper, the Radix-4 16-FFT algorithm with CFFT were designed using VHDL (Very High Speed Integrated Circuit Design Hardware Description Language) and this design is useful for OFDM application.In this paper the analysis of FFT with radix-2 2 designed using VHDL and their performance are analysed.
Bactericidal Effects of Povidone-iodine and Chlorhexidine Gluconate on Coagulase-positive Staphylococci

We aimed to evaluate the in vitro bactericidal efficacy of two routine antiseptics used in veterinary hospital, povidone-iodine and chlorhexidine gluconate in isopropanol (CGI),against canine coagulase-positive staphylococci (CoPS). Twenty CoPS were divided into 5 methicillin-resistant Staphylococcus pseudintermedius (MRSP) and 5 isolates each of S. pseudintermedius, S. aureus and S. schleiferi subsp. coagulans defined as methicillin-susceptible CoPS (MSCoPS). The bactericidal efficacy was determined by broth microdilution according to European Standard EN 1656:2000 at concentrations of 0.1, 1 and 10% PI and 0.5, 1 and 2% CGI for 15s, 30s, 45s, 1 min, 3 min and 5 min, respectively. There was no difference in susceptibility values between the strains. Regarding the fastest bactericidal effects, all tested CoPS were killed with 0.1% PI within 45s and 0.5% CGI within only 15s.

Image Mapping and Object Removal Using ADM in Image Inpainting: Review

:- Image inpainting is a technology for restoring the damaged parts of an image by referring to the information from the undamaged parts to make the restored image look “complete”, “continuous” and “natural”. Inpainting traditionally has been done by professional restorers. For instance, in the valuable painting such as in the museum world would be carried out by a skilled art conservator or art restorer. But this process is manual so it is time consuming. Digital Image Inpainting tries to imitate this process and perform the Inpainting automatically. The aim of this work is to develop an automatic system that can remove unwanted objects from the image and restore the image in undetectable way. Among various image inpainting algorithms Alternating Direction Method (ADM) is used for image restoration. ADM works well for solving inverse problem. In this paper, various applications of ADM method for image restoration are discussed.
INVESTIGATION OF MECHANICAL PROPERTIES OF CHITOSAN BASED FILMS: A REVIEW

The present paper describes the investigation of mechanical properties of chitosan based films. The mechanical strength of the chitosan blends demonstrated that they are able to support tensions and other loads. Government concern over the environment, the depletion of fossil fuels, and climate change has promoted the development of bio nanocomposites. Compared to polymeric resources from petroleum, natural polymers from renewable resources have the advantages of biodegradability, biocompatibility, non-toxicity, high reactivity, low cost and ease of availability. The proper utilization of crab shell waste not only solves the problem of their disposal but also forms the basis for many potential products used in the fields such as textiles, photography, medicine, agriculture, food processing etc. Therefore, the aim of this investigation is to enhance the utilization of biopolymer and help to minimize the environmental pollution. The investigation of the mechanical properties of chitosan films are required to understand the mechanical behavior of the chitosan based films. Tensile strength and Percentage Elongation at Break of the films determine their performance and integrity during storage, utilization and handling. Due to low mechanical strength of chitin and chitosan, it is required to modify some of its properties so that they can act as bio adhesives, nanocomposites, waste material which pollutes the environment.
Isolation and Characetrisation of Pathogens from Various Clinical Samples: A Step towards Prevention of Infectious Diseases

When bacterial diagnosis is considered with its antibiotic profiles, it can do wonders in preventing antibiotic resistance. This of course will help clinicians to write accurate, right and complete prescription without need of broad spectrum or antibiotic combination therapy. This is the only policy that is very simple and that very effective with no big limitations to reduce antibiotic resistance along with Multi drug resistance. Used for disease prevention and infection control procedures this data can be used to protect people now and in future. A total number of 908 clinical samples i.e., urine, blood, pus, other body fluids were collected in the laboratory in the period of two years. The samples were streaked on various culture media for bacterial growth and incubated at 37 o C for 24 hours. The plates of the agar media were observed after 24 hours of incubation to identify the types and number of colonies. The plates that were showing no growth were reincubated for next 24 hrs before confirming them as sterile. The results were variable with various types of pathogens in different clinical samples. E.coli was found to be the main causative agent in almost clinical infections.
