Simulating Vehicle Movement and Multi-Hop Connectivity from Basic Safety Messages
The Basic Safety Message (BSM) is a standardized communication packet that is
sent every tenth of a second between connected vehicles using Dedicated Short
Range Communication (DSRC). BSMs contain data about the sending vehicle's
state, such as speed, location, and the status of the turn signal. Currently,
many BSM datasets are available through the connected vehicle testbeds of U.S.
Department of Transportation from all over the country. However, without a
proper visualization tool, it is not possible to analyze or visually get an
overview of the spatio-temporal distribution of the data. With this goal, a web
application has been developed which can ingest a raw BSM dataset and display a
time-based simulation of vehicle movement. The simulation also displays
multi-hop vehicular network connectivity over DSRC. This paper gives details
about the application, including an explanation of the multi-hop partitioning
algorithm used to classify the vehicles into separate network partitions. A
performance analysis for the simulation is included, in which it is suggested
that calculating a connectivity matrix with the multi-hop partitioning
algorithm is computationally expensive for large number of vehicles
Association Rules Mining Based Clinical Observations
Healthcare institutes enrich the repository of patients' disease related
information in an increasing manner which could have been more useful by
carrying out relational analysis. Data mining algorithms are proven to be quite
useful in exploring useful correlations from larger data repositories. In this
paper we have implemented Association Rules mining based a novel idea for
finding co-occurrences of diseases carried by a patient using the healthcare
repository. We have developed a system-prototype for Clinical State Correlation
Prediction (CSCP) which extracts data from patients' healthcare database,
transforms the OLTP data into a Data Warehouse by generating association rules.
The CSCP system helps reveal relations among the diseases. The CSCP system
predicts the correlation(s) among primary disease (the disease for which the
patient visits the doctor) and secondary disease/s (which is/are other
associated disease/s carried by the same patient having the primary disease).Comment: 5 pages, MEDINFO 2010, C. Safran et al. (Eds.), IOS Pres
Land, development and the political class: In a translocal ‘Londoni’ village
This article expands Akhil Gupta’s (1995, American Ethnologist, 22(2), 375–402) thesis of ‘blurred boundaries’ between ‘the state’ and ‘society’ in South Asia to incorporate the impact of historic labour migrations, which complicate established conceptions of the state in Bangladesh. Based on ethnographic fieldwork in an area of high migration to the UK, the article draws attention to a class of transnational politicians, and their intra-class conflicts of interest, in shaping local-level politics. The article supports Faguet’s (2017, Modern Asian Studies 51(6), 1668–94) contention that the decentralisation of local government has led to the emergence of vernacularised political economies that operate in the shadow of the state, which are also intrinsically facilitated by it. It suggests that state actors appropriate symbols, offices and resources, together with traditional authority and kinship dynamics, to create an idiosyncratic polity. Aspiration towards power that might lead to the occupation of state offices are determined by either the aspirant’s status as a British citizen (Londoni) or through intimate social and economic connections to Britain through kinship (gushti) networks. The article thus makes a broader contribution to the existing literature on the anthropology of the state, transnational politics and the nexus of power, money and migration in postcolonial contexts
Hematocrit Level on Blood flow through a Stenosed Artery with Permeable Wall: A Theoretical Study
The paper deals with the hematocrit level on resistance of flow, wall shear stress in a stenosed artery of permeable wall. In the paper we have developed and solved some theoretical formulas based on stenosis and hematocrit effects. The results highlight that the resistance of flow increases for increasing of stenosis height where the hematocrit level (35%-45%) has significant effects. Moreover, the effects of slip parameter and Darcy number due to permeability of the wall on resistance of flow have been investigated. The effects of hematocrit level, slip parameter and Darcy number have been focused on wall shear stress of the permeable inner surface of the artery which has a fashion of downwardly concave for increasing of the z-axis of the artery
