    On Large Deviation Property of Recurrence Times

    Full text link
    We extend the study by Ornstein and Weiss on the asymptotic behavior of the normalized version of recurrence times and establish the large deviation property for a certain class of mixing processes. Further, an estimator for entropy based on recurrence times is proposed for which large deviation behavior is proved for stationary and ergodic sources satisfying similar mixing conditions.Comment: 5 pages, International Symposium on Information Theory 201

    A divider of frequency with minimal power & greater speed with multi modulus is elaborated along design of a PLL. In this document by making use of a ff initiated by a pulse is plowed by which a definite divider with 2 levels can improvise the frequency of function & deduce decadence of power. A constituent which is adaptive s formulated to be retained in a divider with great mode of saving in power. The frequency of a defined divider with 2 levels in accordance to CMOS of 130 nm process may attain 4 GHz. The basic decadence f power is division by 49 mode at 63 uW with frequency of 1 GHz or 156uW at 4 GHz. In a contrast of the counter of Johnson FD, frequency of a divider with 2 levels is improvised & so the proportion of optimization of power

    Second law analysis in three-dimensional MHD boundary layer flow and heat transfer of a rotating Casson fluid over a stretching surface has been investigated. Such flow problems have relevance in extraction and manufacturing of rubber and polymer sheets. Solution of these problems is of great interest as they serve a practical purpose. Partial differential equations governing flow and heat transfer have been transformed into non-linear ordinary differential equations by using suitable similarity transformations. These non-linear differential equations have been solved numerically by using shooting techniques with fourth order Runge-Kutta method. Effects of Casson fluid parameter β, rotation parameter λ, Prandtl number Pr and magnetic field parameter M on velocity profile, temperature profile and skin friction number have been analyzed and depicted through graphs and tables. Entropy generation number and Bejan number have also been obtained and discussed

    Background: India accounts for 24% of global neonatal mortality. It is important to study the mortality and morbidity pattern as it helps to implement new treatment protocols, interventions, planning and policy making which helps in better survival and improvement in the quality of life among survivors. The aim of the project study was to determine the causes of morbidity and mortality in neonates admitted in our hospital.Methods: This study was conducted at Special Newborn Care Unit (SNCU) of Veer Chandra Singh Garhwali Government Institute of Medical Science and Research providing level II neonatal care. This is a retrospective hospital based observational study. Data from admission and discharge registers were extracted, compiled and analyzed from March 2016 to February 2018. Neonates taken against medical advice and those referred to tertiary care centers were excluded in calculation of survival outcome. Statistical analysis was done in form of percentage, proportions and chi square test was used to find statistical significance.Results: 1582 neonates were admitted during the study period. 60.80% were inborn and 39.20% were outborn. 59.54% were male and 40.46% were female. Major causes of admission were jaundice (24.72%), sepsis (20.48%), birth asphyxia (18.52%), meconium aspiration syndrome (10.11%). Birth asphyxia was the major cause of mortality, followed by sepsis and prematurity. Mortality was more in outborn babies 14.67% compared to inborn babies 9.80%.Conclusions: Neonatal jaundice, birth asphyxia and sepsis were the commonest causes of morbidity. Common causes of mortality were birth asphyxia and sepsis and prematurity. More deliveries at institutions with SNCU facility, early identification of danger signs and timely referral to tertiary care centers can prevent neonatal deaths

    Repair of Sunken Floor by Integrated Approach: A Case Study

    Get PDF
    The floors and non load bearing walls of a house, having expansive black cotton soil underneath, have been repaired by two methods. A part of the damaged house floors and walls were repaired by the conventional method i.e. removing the expansive soil completely and replacing with non expansive granular material. The remaining part was repaired by integrated approach as described later by Jain and Mewade (2010). The Jain and Mewade (2010) approach consists of removing the expansive soil underneath the damaged floor by about 0.5m, making 50mm diameter, 1m deep holes at 0.75m centre to centre and filling lime slurry in the holes. The broken floor debris and non expansive soil was then filled up to the floor base level and the cement concrete floor was reconstructed. The floor constructed by removal of expansive soil by 1.5m depth in the first method and partial removal and making lime piles in the second method are performing well with no sign of settlement or unevenness any where. The paper presents the success story of one such house repaired by these methods in the year 2008. The second method requires only partial removal and replacement of problematic soil beneath the floor and therefore is fast and economical in comparison to conventional method
