Aspects of superconductivity and fractionalization

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Physics, 2005.Includes bibliographical references (p. 37).Since their discovery in mid 80's, a complete theory of high temperature superconductors is yet to take its final shape. Theory of fractionalization attempts to explain the phenomenon by assuming that the electron is split into two particles, chargon and spinon, carrying charge and spin respectively. Although capable of producing the qualitative features of the phase diagram, this theory is not been able to account for a number of experimental observations. A simple mean field model based on fractionalization ideas is proposed in this work which can possibly get around some of the drawbacks of the original fractionalization theory. Chapter one discusses various aspects of superconductivity along with BCS theory and chapter two talks about the motivation behind considering this model along with its basic features.by Dinesh V.

A Review Paper on Behavior of Node in MANET

MANET Mobile ad-hoc networks (MANETs) is wireless network composed of various wireless equipment connected without any pre-existent infrastructure. It connects various types of equipment through wireless networking. But whenever this network has to communicate with other system it takes the help of its neighbor to send the data so it needs the corporation from other nodes of the network. Also when any node is no relation with the sending data it acts as a medium to forward the unrelated traffic. This is the ideal condition which is expected but in real world most nodes may have selfish behavior who are not corporate to forward the packet to save the resource. So in this paper we are going to study of the selfish node in MANET & their behaviors in various aspects. DOI: 10.17762/ijritcc2321-8169.160414

Clinical and bacteriological study of neonatal septicaemia in a tertiary care hospital

Background: Neonatal sepsis is a clinical syndrome of bacteraemia characterized by systemic signs and symptoms in the first month of life. It is the leading causes of neonatal mortality and morbidity. Early diagnosis and treatment with appropriate antibiotics is important to improve the prognosis of neonatal sepsis. Our objectives were to study the organisms causing neonatal septicaemia, associated risk factors, to correlate CRP with blood culture and to study mortality rate in neonatal septicaemia.Methods: The study of 2 years included clinically suspected cases of neonatal septicaemia admitted in NICU. 566 blood samples were collected, processed and isolates were identified. Maternal and neonatal risk factors were studied. CRP test was done by slide agglutination test.Results: Blood culture was positive in 205 (36.22%) cases. Among the culture positive cases, 128 (62.44%) were males and 77 (37.56%) females with male to female ratio of 1.66:1. Early onset sepsis was present in 137 (66.83%) and late onset sepsis in 68 (33.17%) cases. 107 (52.20%) were low birth weight babies. The most common neonatal risk factor was prematurity 75 (36.58%) and maternal risk factor was prolonged rupture of membrane 65 (31.71%). gram negative bacilli 144 (70.24%) were found to be common cause of sepsis than gram positive cocci 61 (29.76%), Klebsiella pneumoniae 54 (26.34%) being most common pathogen. Out of 566, CRP test was positive in 244 (43.10%) cases. Mortality rate was 23.41%.Conclusions: Neonatal septicaemia is a life-threatening emergency. The study of etiological profile and CRP test plays a significant role

Emotion Recognition by Using Bimodal Fusion

In order to improve the single-mode emotion recognition rate, the bimodal fusion method based on speech and facial expression was proposed. Here emotion recognition rate can be defined as ratio of number of images properly recognized to the number of input images. Single mode emotion recognition term can be used either for emotion recognition through speech or through facial expression. To increase the rate w e combine these two methods by using bimodal fusion. To do the emotion detection through facial expression we use adaptive sub layer compensation ( ASLC) based facial edge detection method and for emotion detection through speech we use well known SVM . Then bimodal emotion detection is obtained by using probability analysis

Finger Knuckle Based Biometric Identifier Using Principal Component Analysis, Feature Extraction and K-NN Classifier

Amidst several biometric measures, the figure knuckle surface is becoming a preferred choice of researchers due to its natural ease of reproducibility and verification. For any purpose of personal identification or crime analysis, figure knuckles surface do not need to be a voluntarily presented, they get exposed naturally. Specific line pattern on the figure knuckle surfaces can be used as effective biometric measure on their own or in combination with other biometrics. Present paper demonstrates the development of a figure knuckle based biometric identification system. The system incorporates principal component analysis (PCA) for feature extraction out of pre-processed and enhanced input image as extracted from knuckle surface video capture. Secondly the system employs k-nn classifier as personal identification algorithm. The system has been tested, verified and validated with many sample test experiments. The paper illustrates the working of the system with detailed intermittent snapshots

Ascites in CML: a rare extramedullary manifestation

Ascites in chronic myeloid leukemia (CML) as an extramedullary manifestation is rarely reported in the literature. A young 23 year old female of chronic myeloid leukemia presenting with extramedullary disease as massive ascites. All stages of granulocytes and a few blasts similar to peripheral blood smear was present in ascitic fluid. Based on clinical symptoms and signs, bone marrow examination, ascitic fluid cytology and ultrasonography of abdomen she was diagnosed as a case of Chronic myeloid leukemia in chronic phase with extramedullary disease as massive ascites. After starting treatment with Imatinib mesylate favourable response was observed
