USE OF DISCRIPTOR FINGERPRINTS TO SIMILARITY AND CLUSTER ANALYSIS OF BIODIESEL FUELS ON THE BASIS OF THEIR COMPOSITION AND PROPERTIES. INTRODUCTION OF FUZZY DESCRIPTOR FINGERPRINTS[ ]


A novel approach for similarity search of different objects in clusters, the fuzzy descriptor fingerprints has been devised. Each cluster is characterized by a fuzzy descriptor fingerprint which is formed of real values instead of Boolean values 0=false and 1=true. A novel similarity index for similarity comparison between Boolean and fuzzy fingerprints, the Fuzzy Factor (FF) has been introduced. This method has been applied to the similarity and cluster analysis of biodiesel fuels

Study of Pratt Truss bridge with post-tension members of different layouts for strengthening[ ]


Majority of steel bridges in India and abroad are structurally deficient and functionally obsolete. The total no of bridges in India is 127154, out of which 56169 or more bridges are more than 80 years old. Thus 44.0 percent of bridges that we commute have outlived their life. These bridges are strengthened by post tensioned tendon layouts to meet the current and future loading and traffic requirements. The stiffness method of analysis is suggested. The layouts are straight, one-drape, and two drape tendon layouts are proposed and the tendons do not coincide with the truss members. However the tendon layout can be internal or external. Applications of these methods are rare in steel structures, but high-strength steel cables can be used effectively to increase the working capacity of steel structure.

Optical Character Recognition for Running C Code[ ]


‘Tesseract’ is an OCR (optical character recognition) engine for various operating systems. In the following paper, using the concept of ‘Tesseract’, a new code runner has been proposed, named as, which can also be used to run handwritten codes. An Android application is developed which enables a person to take a picture of a piece of code by an android phone and within seconds, the output of the code is displayed on the screen. Earlier, it has been observed that the OCR engine works only for the printed text with good accuracy. But the newly developed code runner helps in detecting handwritten codes by customizing and training the system. This code runner reduces the problem and saves the time for the coders by directly clicking the picture and getting the output simultaneously on the mobile screen itself.

Preliminary Tunes of PYTHIA to the Minimum Bias data from Hadron Collider Experiments[ ]


Current high energy event generation softwares combines Quantum Chromodynamics and phenomenological models which re-quires many free parsamters. These relatively free parameters need to be tuned to describe the experimental data well. We present tuning of Monte Carlo event generator PYTHIA6 to the published Minimum Bias data from high energy proton-(anti)proton collider experiments, Large Hadron Collider and Tevatron. Five parameters of Multiple Parton Interactions model are selected and tuned using two different parton density functions. The results are compared to the tunes from ATLAS called AMBT1 tune. Studies have shown that the parameter values depend sensitively on the chosen hadronisation tuning and the chosen PDF set.

Classification of normal and anomalous regions in 3D human cerebrovascular phantom[ ]


Detection of anomaly in cerebrovasculature is a vital job as it can lead to predict and assess the cerebrovascular diseases. Classification of anomalous part in human cerebrovascular phantom can help to detect some of the vascular diseases. Disease like aneurysm causes a number of deaths worldwide and so it is very crucial for clinicians to predict or assess it. Hemodynamics is commonly thought to play an important role in the mechanisms of development, progression, and rupture of aneurysm. It is reasonable to assume that rupture risk assessment can be improved by incorporating hemodynamic analysis on the parameter like wall shear stress(wss), velocity, static pressure information. So to compare the hemodynamic parameters on different cerebrovascular phantoms with and without aneurysm and to find some features from that for pattern classification, carries a significant role in prediction of occurrence of aneurysm and subsequently rupture risk of the same.

Experimental Study on the use of Nano Chemical and Cement in the modification of Subgrade[ ]


Weak soils are most likely to cause damage to all structures including road pavements. Stabilization of soil is done to avoid these damages and improve strength. It also helps in improving the compaction characteristics of soil. In this work, chemical stabilization of black cotton soil was done to improve the subgrade. Soaked CBR test was conducted on soil treated with nano chemical Terrasil with Cement as binder. The percentage addition of Terrasil was varied from 0.03%, 0.05%, 0.07% and 0.09% inorder to find the optimum content of the nano chemical. With optimum percentage of Terrasil and with varying percentage of cement such as 1%, 2%, 3%, and 4% on soil, CBR test was conducted.The maximum CBR value is obtained at a combination of 0.07% Terrasil and 3% Cement. CBR percentage was increased by 3.6 times when compared to soil without stabilizer. SEM and EDAX analysis was done to know the morphology and chemical composition in the unstabilized and stabilized soil sample.

Impact of National Security on Food Security: Evidence from Pakistan[ ]


Pakistan is one of the country in the developing countries which is known for its agricultural and economic growth but still the food security conditions are not satisfactory. Although the country is trying to meet the MDG’s by increasing the food security and reducing the hunger in the country. All the scholars and philosophers are agreed on the point that food insecurities occur when there are insecurities at national level and when we talk about security at national level then it not only include use of force and military might to protect the country from conventional foes and other non-state elements but also include multidimensional security. These dimensions include economic, environmental, security of society, security of natural resources and war risks. This study targets to measure the relationship between national security and food security conditions in Pakistan. For getting results, quantitative regression analysis is used and correlation is checked between all the variables of the food security and national security. For analysis the collection of data is done by the assistance of World Bank, Pakistan Statistical Bureau, UNDP, UCDP, FAO, and the Pakistan Economic Survey. This study allows us to analysis the economic instability, an increase in war risk, insecurity in society, security of environment and insecurity of natural resources and its correlation with food insecurity. Analysis of the results, help us to draw recommendation which are most appropriate and feasible according to the need of the country.

INFLATION VIA MODIFIED GRAVITY & INFLATION IN THE MODIFIED STAROBINSKY MODEL AND IN THE EINSTEIN FRAME[ ]


In the present paper we consider the Starobinsky model of inflation, and find that it is connected to matter scalar field models with a non-minimal coupling to gravity. We then consider quantum induced marginal deformations of the Starobinsky action, and find that such deformations significantly shift the predicted tensor-to-scalar towards higher values. At last we discuss sources for these corrections. In this paper, we review inflation in modified gravity, particularly F(R) gravity, based on Ref. [33]. The deviation of F(R) gravity from general relativity may be interpreted as a kind of quantum corrections in the early universe, or such a modification of gravity could be motivated by the so-called ultraviolet (UV) completion of quantum gravity. In fact, the Starobinsky inflation [32] can be regarded as inflation induced by the modification term of R2 from general relativity. We here attempt to examine inflation by the other forms of modification of gravity.

Analysis of Major, Minor and Trace elements related to Ethiopia Cereal crops using EDXRF technique[ ]


The elemental analysis of cereal crops grown in Ethiopia namely Barley (Hordeum vulgare), Maize (Zeama mays), Finger millet (Eleusine coracana), Sorghum (sorghum bicolor) and Wheat (Triticum aestivum) samples were carried out using EDXRF spectrometer. The concentration of 16 elements (Ca, K, S, P, Zn, Cu, Ni, Co, Fe, Mn, Cr, As, Pb, Sr, Rb and Br) were obtained in the above mentioned five selected cereal crops. The results demonstrated that the relative concentrations of obtained elements in these cereal crops are different from one another. Ca is more in millet while it is least in maize. Contrary to this, K is found high in maize and low in wheat but high concentration of P was present in barley and minimum quantity was obtained in sorghum. Significantly in the present work the concentration of heavy metals were found to be with low level concentration besides the absence of P and Mn elements in maize and P in sorghum were noticed. On the other hand high content of calcium, potassium, zinc and Iron micronutrients were found in all cereal species.

A coastal Lake’s Hydro-chemistry: Sidi Boughaba Case, North Western Morocco[ ]


In order to determine the factors and the mechanisms which control the chemistry and the salinity of the waters of SidiBoughaba Lake, the waters of the lake environment and those taken from a well near the lake, we subjected these waters to a hydro-chemical control at a trimestrial sampling rate. The analyzes revealed a basic pH between 8.38 and 9.03, an electrical conductivity in the range of 12.40 to 17.41 mS/cm and high Sodium and Chloride contents up to the respective values of 3698 mg/L and 6625 mg/L for the waters of the lake on the one hand, and a neutral pH and a low mineralization for those of the wells, on the other hand. The results’ projection on the Piper Diagram revealed the presence of a hydrochloric-sodium facies for the lacustrine waters and a mixed facies for those of the wells. The comparison between the chloride content with the rest of the main elements and the increasing levels of Sodium and Chlorides mentioned above shows that the hydrochemistry of the lake’s water is due to the effect of marine spray, evaporation’s cycles, while the Ca2+- Mg2+ exchange is due to the water-carbonate interaction, and Na+ - Ca2+ or Na+ - Mg2+ exchange is due to the basic exchanges, and the sulphates’ reduction. The calculation of saturation indices revealed that SidiBoughaba Lake waters are under-saturated with evaporite minerals (halite, gypsum and anhydrite) and supersaturated with carbonate minerals (calcite, aragonite and dolomite).

Shift in the Role of the School Principal: Administrator to Instructional Leader[ ]


School is the most important institution in the socialization of children because it can cause an impact on children’s development. Principal’s leadership is often viewed as a major focus of efforts to pursue and achieve excellence in education. In other words, excellence or success of a school is influenced by effective principal leadership. Schools can make a difference to the level of students’ academic performance; however, good or poor school depends on the person who leads the school. Students' academic performance is not only dependent on the performance of the school, but it is also influenced by the management and leadership of the principal. The paper discussed how to change the role of principal as an administrator to instructional leader. The method followed is by defining instructional leadership, knowledge and the instructional leader, skills and the instructional leader, instructional leadership and academic performance, and principal roles as instructional leadership. Going by these the paper recommended the redefinition of the role of principals, by eliminating bureaucratic structures and reinventing relationships in the school setting. And that principals should change their activities as instructional leaders by focusing on instruction; building a community of learners; sharing decision making; sustaining the basics scarce resources; leveraging time; supporting ongoing professional development for all staff members; redirecting resources to support a multifaceted school plan; and creating a climate of integrity for effective teaching and learning.
