Detection of gravitational waves from inspiraling compact binaries using a network of interferometric detectors

We formulate the data analysis problem for the detection of the Newtonian waveform from an inspiraling compact-binary by a network of arbitrarily oriented and arbitrarily distributed laser interferometric gravitational wave detectors. We obtain for the first time the relation between the optimal statistic and the magnitude of the network correlation vector, which is constructed from the matched network-filter. This generalizes the calculation reported in an earlier work (gr-qc/9906064), where the detectors are taken to be coincident.Comment: 6 pages, RevTeX. Based on talk given at GWDAW-99, Rom

Integrated approach for efficient power consumption and resource allocation in MIMO-OFDMA

The growing interest towards wireless communication advancement with smart devices has provided the desired throughput of wireless communication mechanisms. But, attaining high-speed data packets amenities is the biggest issue in different multimedia applications. Recently, OFDM has come up with the useful features for wireless communication however it faces interference issues at carrier level (intercarrier interferences). To resolve these interference issues in OFDM, various existing mechanisms were utilized cyclic prefix, but it leads to redundancy in transmitted data. Also, the transmission of this redundant data can take some more power and bandwidth. All these limitations factors can be removed from a parallel cancellation mechanism. The integration of parallel cancellation and Convolution Viterbi encoding and decoding in MIMO-OFDMA will be an effective solution to have high data rate which also associations with the benefits of both the architectures of MIMO and OFDMA modulation approaches. This paper deals with this integrated mechanism for efficient resource allocation and power consumption. For performance analysis, MIMO-OFDMA system is analyzed with three different approaches likeMIMO-OFDM system without parallel cancellation (MIMO-OFDMA-WPC), MIMO-OFDMA System with parallel cancellation (MIMO-OFDMA-PC) and proposed IMO-OFDMA system with parallel cancellation and Convolution Viterbi encoding/decoding (pMIMO-OFDMA-PC &CVed) for 4x4 transmitter and receiver. Through performance analysis, it is found that the proposed system achieved better resource allocation (bandwidth) with high data rate by minimized BER rate and achieved least power consumption with least BER

A study on the effectiveness of Guggulu based Karanja Ksharasutra in comparison with Apamarga Ksharasutra in the management of Shalyaja Nadivrana with special reference to Pilonidal Sinus

Shalyaja Nadivrana is an Agantuja variety of Vrana. Nidana Panchaka and treatment is extensively described in Sushruta Samhita - Nidhana and Chikitsa Sthana. Presence of Shalya in the tract is an obstacle to its healing. Management of Nadivrana includes Ksharasutra therapy. The pilonidal sinus is an acquired sinus that develops in young, hirsute men, usually in the intergluteal cleft caused by the intrusion of hair into the skin, causing an abscess and gradually forming a sinus. The study was conducted on 40 randomly assigned patients at SJAUM Hospital, Bengaluru by dividing them into 2 groups - Group A and Group B. These groups were treated with Guggulu-based Karanja Ksharasutra and Apamarga Ksharasutra respectively. Assessment of pain, discharge, LOT, tenderness, and induration in Group A showed 91.67%, 91.3%, 99.9%, 85.19%, 95% and 75.6% improvement and Group B showed 87.5%, 86.96%, 100%, 78.6% and 97.37% improvement respectively. Group A’s overall result was 89.5% and Group B’s overall result was 89.9%. The mean UCT of Group A was 8.3 days/cm and Group B was 7.9 cm/day with p -value <0.05 which is significant. The study showed that the trial drug was as good as the control drug in the management of Shalyaja Nadi Vrana

Predictive Maintenance of Cash Dispenser Using a Cognitive Prioritization Model

In this technical paper, we address the issue of predicting cash dispenser (addressed as ‘Device’ henceforth) failure by harnessing the power of humungous data from service history, logs, metrics, transactions, and plausible environmental factors. This study helps increase device availability, enhanced customer experience, manage risk & compliance and revenue growth. It also helps reduce maintenance cost, travel cost, labour cost, downtime, repair duration and increase meantime between failures (MTBF) of individual components. This study uses a cognitive prioritization model which entails the following at its core; a) Machine Learning engineered features with highest influence on machine failure, b) Observation Windows, Transition Windows and Prediction Windows to accommodate various business processes and service planning delivery windows, and c) A forward-looking evaluation of emerging patterns to determine failure prediction score that is prioritized by business impact, for a predefined time window in the future. The model not only predicts failure score for the devices to be serviced, but it also reduces the service miss impact for the prediction windows

Non-degenerate, three-wave mixing with the Josephson ring modulator

The Josephson ring modulator (JRM) is a device, based on Josephson tunnel junctions, capable of performing non-degenerate mixing in the microwave regime without losses. The generic scattering matrix of the device is calculated by solving coupled quantum Langevin equations. Its form shows that the device can achieve quantum-limited noise performance both as an amplifier and a mixer. Fundamental limitations on simultaneous optimization of performance metrics like gain, bandwidth and dynamic range (including the effect of pump depletion) are discussed. We also present three possible integrations of the JRM as the active medium in a different electromagnetic environment. The resulting circuits, named Josephson parametric converters (JPC), are discussed in detail, and experimental data on their dynamic range are found to be in good agreement with theoretical predictions. We also discuss future prospects and requisite optimization of JPC as a preamplifier for qubit readout applications.Comment: 21 pages, 16 figures, 4 table

A Cross-sectional Study on Prescribing Pattern for Children at Primary Health Care Clinics

Background: Rational prescribing for children is very essential as there is increased risk from the use of medicines in them due to multiple reasons ranging from altered pharmacokinetics to long-term side effects. Drug-related needs of children must be assessed on individual basis to meet appropriate health care outcomes. Aim: This cross-sectional descriptive study aims at assessing drug use pattern and rationality in prescribing pattern as per World Health Organization (WHO) core prescribing indicators. Material and methods: A cross-sectional and prospective study was carried out in private primary health care clinics of Hyderabad, Telangana State. A total number of 300 prescriptions for children were reviewed. Patients’ demographic characteristics, diagnosis and drugs prescribed were recorded in a prestructured and validated data collection form. Results: Average number of drugs per prescription were 1.92. Fever and upper respiratory tract infections were found to be common complaints in this age group. Paracetamol was the most commonly prescribed medication and among prescribed antibiotics, fluoroquinolones occupied the major part. About 67.3% of drugs were from the WHO Model List of Essential Medicines for Children. The percentage of drugs prescribed with generic names was very less. Conclusion: In this study, it was found that the prescription pattern in the selected primary health care centers in Hyderabad was in compliance with the WHO prescribing indicators, except the generic prescribing practice

The Global Survey of the Electrical Energy Distribution System: A Review

This paper gives a review of energy scenario in India and other countries. Today’s demand of the world is to minimize greenhouse gas emissions, during the production of electricity. Henceforth over the world, the production of electrical power is changing by introducing abundantly available renewable energy sources like sun and wind. But, because of the intermittent nature of sustainable power sources, the electrical power network faces many problems, during the transmission and distribution of electricity. For resolving these issues, Electrical Energy Storage (EES) is acknowledged as supporting technology. This paper discusses about the world electrical energy scenario with top renowned developed countries in power generation and consumption. Contribution of traditional power sources changed after the introduction of renewable energy sources like sun and wind. Worldwide Agencies are formed like International Energy Agency (IEA), The Central Intelligence Agency, (CIS) etc. The main aim of these agencies is to provide reliable, affordable and clean energy. This paper will discuss about the regulatory authority and government policies/incentives taken by different countries.  At the end of this paper, author focuses on obstacles in implementation, development and benefits of renewable energy

Threshold Corrections to the Bottom Quark Mass Revisited

Threshold corrections to the bottom quark mass are often estimated under the approximation that tan$\beta$ enhanced contributions are the most dominant. In this work we revisit this common approximation made to the estimation of the supersymmetric threshold corrections to the bottom quark mass. We calculate the full one-loop supersymmetric corrections to the bottom quark mass and survey a large part of the phenomenological MSSM parameter space to study the validity of considering only the tan$\beta$ enhanced corrections. Our analysis demonstrates that this approximation underestimates the size of the threshold corrections by $\sim$12.5% for most of the considered parameter space. We discuss the consequences for fitting the bottom quark mass and for the effective couplings to Higgses. We find that it is important to consider the additional contributions when fitting the bottom quark mass but the modifications to the effective Higgs couplings are typically $\mathcal{O}$(few)% for the majority of the parameter space considered.Comment: 24 pages, 9 figures, 1 table; error in analysis corrected, results substantially modified, version to be submitted to JHE
