Design and Implementation of a Measurement-Based Policy-Driven Resource Management Framework For Converged Networks
This paper presents the design and implementation of a measurement-based QoS
and resource management framework, CNQF (Converged Networks QoS Management
Framework). CNQF is designed to provide unified, scalable QoS control and
resource management through the use of a policy-based network management
paradigm. It achieves this via distributed functional entities that are
deployed to co-ordinate the resources of the transport network through
centralized policy-driven decisions supported by measurement-based control
architecture. We present the CNQF architecture, implementation of the prototype
and validation of various inbuilt QoS control mechanisms using real traffic
flows on a Linux-based experimental test bed.Comment: in Ictact Journal On Communication Technology: Special Issue On Next

Population response of triploid grass carp to declining levels of hydrilla in the Santee Cooper Reservoirs, South Carolina
Approximately 768,500 triploid grass carp (
Ctenopharyngodon
idella
Valenciennes) were stocked into the Santee Cooper
reservoirs, South Carolina between 1989 and 1996 to
control hydrilla (
Hydrilla verticillata
(L.f.) Royle). Hydrilla
coverage was reduced from a high of 17,272 ha during 1994
to a few ha by 1998. During 1997, 1998 and 1999, at least 98
triploid grass carp were collected yearly for population monitoring.
Estimates of age, growth, and mortality, as well as
population models, were used in the study to monitor triploid
grass carp and predict population trends. Condition declined
from that measured during a previous study in 1994.
The annual mortality rate was estimated at 28% in 1997, 32%
in 1998 and 39% in 1999; however, only the 1999 mortality
rate was significantly different. Few (2 out of 98) of the triploid
grass carp collected during 1999 were older than age 9.
We expect increased mortality due to an aging population
and sparse hydrilla coverage. During 1999, we estimated about
63,000 triploid grass carp system wide and project less than
3,000 fish by 2004, assuming no future stocking.

Sensory textile-bacterial hybrids: textile-bacteria fusion to impart forest-associated scents
This research paper presents a study on the development of living textile-bacterial hybrids, focusing on the scent produced by Streptomyces violaceruber, a bacterial species, throughout its growth phase. The objective of this study was to observe scent profiles of S. violaceruber on two different fibres, cotton, and linen, and analyse the potential impact of fibre properties on scent profile, intensity, and duration. In doing so the research suggests potential opportunities to curate living scent through textiles and the generation of sensory textile-bacterial hybrids. Interdisciplinary methods were applied to compare changes in the volatile compounds present and identify fibres and fabrication processes most suitable to create a living textile. The paper reports on the development of textile samples that are infused with S. violaceruber and observed for their subjective scent as well as the volatile compounds, which were analysed via gas chromatography. The findings of this study confirmed the presence and development of bacterial scents on textiles during bacterial growth. The scents identified included earthy, soil-like, floral, jasmine, and fruity notes, offering potential for further exploration in fibre and yarn selection, as well as the structural design of the textile. This research contributes to the field of biotextiles by examining the influence of textile fibres and knitted textiles on bacterial volatile compounds. It establishes a platform for investigating how different fibres and structural factors influence the bacterial scent profile and provides valuable insights for the future development of living sensory textiles and their integration into various applications
Ethical and methodological issues in engaging young people living in poverty with participatory research methods
This paper discusses the methodological and ethical issues arising from a project that focused on conducting a qualitative study using participatory techniques with children and young people living in disadvantage. The main aim of the study was to explore the impact of poverty on children and young people's access to public and private services. The paper is based on the author's perspective of the first stage of the fieldwork from the project. It discusses the ethical implications of involving children and young people in the research process, in particular issues relating to access and recruitment, the role of young people's advisory groups, use of visual data and collection of data in young people's homes. The paper also identifies some strategies for addressing the difficulties encountered in relation to each of these aspects and it considers the benefits of adopting participatory methods when conducting research with children and young people
