Evaluation of Randomised Controlled Trials Published in Indian Specialty Dental Journals for Statistical Testing of Baseline Differences: A Meta-Epidemiological Study

open access: yesIndian Journal of Dental Research, 2023
Background: In randomised controlled trials (RCTs), the application of a test of significance to compare the baseline differences between the intervention groups is a common practice, though it has been condemned by many researchers.

Comparison of virtual reality and physical simulation training in first‐year radiography students in South America

open access: yesJournal of Medical Radiation Sciences, 2023
Introduction The aim of this study was to comparatively evaluate the learning outcomes achieved by first‐year radiography students educated with either virtual reality (VR) simulation training or physical simulation training. The implementation of VR has

Study designs: Part 5 – interventional studies (II)

open access: yesPerspectives in Clinical Research, 2019
In the fifth piece of this series on research study designs, we continue the discussion on interventional studies (clinical trials), in which the investigator decides whether or not a particular participant receives the exposure (or intervention).

Balanced allocation through random walk [PDF]

open access: yesInformation Processing Letters, 2018
We consider the allocation problem in which $m \leq (1- ) dn $ items are to be allocated to $n$ bins with capacity $d$. The items $x_1,x_2,\ldots,x_m$ arrive sequentially and when item $x_i$ arrives it is given two possible bin locations $p_i=h_1(x_i),q_i=h_2(x_i)$ via hash functions $h_1,h_2$.

Optimal Resource Allocation in Random Networks with Transportation Bandwidths [PDF]

open access: yes, 2009
We apply statistical physics to study the task of resource allocation in random sparse networks with limited bandwidths for the transportation of resources along the links. Useful algorithms are obtained from recursive relations.

Clinical and quality-of-life outcomes after autologous fascial sling and tension-free vaginal tape: a prospective randomized trial

open access: yesInternational Brazilian Journal of Urology, 2009
Purpose: Evaluate the impact autologous fascial sling (AFS) and tension-free vaginal tape (TVT) procedures on quality-of-life in incontinent women. Materials and Methods: Forty-one women were randomly distributed into two groups.

Performance Analysis of Resource Allocation in THz-Based Subcarrier Index Modulation Systems for Mobile Users

open access: yesIEEE Access, 2021
The recent demand for connections to a huge number of users with very high data rates have motivated research communities to investigate communications into the higher frequency bands, such as millimeter waves and TeraHertz (THz) bands.

Optimal Power Allocation for Artificial Noise Under Imperfect CSI Against Spatially Random Eavesdroppers [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2016
In this paper, we study the secure multiantenna transmission with artificial noise (AN) under imperfect channel state information (CSI) in the presence of spatially randomly distributed eavesdroppers.

An Efficient Reactive Power Control Method for Power Network Systems with Solar Photovoltaic Generators Using Sparse Optimization

open access: yesEnergies, 2017
With the incremental introduction of solar photovoltaic (PV) generators into existing power systems, and their fast-growing share in the gross electricity generation, system voltage stability has become a critical issue.

Distributed resource allocation over random networks based on stochastic approximation [PDF]

open access: yesSystems & control letters (Print), 2015
In this paper, a stochastic approximation (SA) based distributed algorithm is proposed to solve the resource allocation (RA) with uncertainties. In this problem, a group of agents cooperatively optimize a separable optimization problem with a linear ...
