Resource allocation for statistical quality of service provision in buffered crossbar switches,

INTERNATIONAL JOURNAL OF COMMUNICATION SYSTEMS, Issue 6 2008
Qiang Duan
Abstract The buffered crossbar switch is a promising switching architecture that plays a crucial role for providing quality of service (QoS) in computer networks. Sufficient amount of resources,bandwidth and buffer space,must be allocated in buffered crossbar switches for QoS provision. Resource allocation based on deterministic QoS objectives might be too conservative in practical network operations. To improve resource utilization in buffered crossbar switches, we study the problem of resource allocation for statistical QoS provision in this paper. First, we develop a model and techniques for analyzing the probabilistic delay performance of buffered crossbar switches, which is described by the delay upper bound with a prescribed violation probability. Then, we determine the required amounts of bandwidth and buffer space to achieve the probabilistic delay objectives for different traffic classes in buffered crossbar switches. In our analysis, we apply the effective arrival envelope to specify traffic load in a statistical manner and characterize switch service capacity by using the service curve technique. Instead of just focusing on one specific type of scheduler, the model and techniques developed in this paper are very flexible and can be used for analyzing buffered crossbar switches with a wide variety of scheduling algorithms.

Current situation of German care homes

INTERNATIONAL JOURNAL OF OLDER PEOPLE NURSING, Issue 4 2008

Aim., The aim of this paper is to explore the situation of and current developments in the German care home sector. Background., Germany, like other Western countries, faces demographic change and subsequently tries to develop structures and processes to achieve a care system which can tackle the increasing number of people in need of care with a variety of quality services. Policy strives to set up structures and instruments to enhance the quality of service provision. Discussion., Figures show that the structures in the care sector are changing in favour to increased privatization of homes, a slight increase in size and improved building structures. In order to tackle the expected changes, a mix of low and high skilled qualification and new job profiles arise in the care sector. Other changes to be observed are the development of new living arrangements and the utilization of new technologies to support the care process. Conclusion., This contribution looks at the socio-demographic changes in care, the statutory developments and the structures of care homes as well as current discussions on future developments.

Epilepsy and intellectual disability

JOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 5 2000
C. Bowley
Abstract A Medline and Psychline literature review of epilepsy in people with intellectual disability was performed. The review has highlighted the importance of the impact of epilepsy on the lives of individuals and their families, affecting physical morbidity, leading to an increased mortality and increasing the care-giving burden. Interventions with a strong evidence base are mainly pharmacological with an increasing body of work on the novel antiepileptic drugs. Surprisingly little research exists into the quality of service provision for this population. The authors suggest three areas for future work: (1) an increasing application of research methodologies such as direct observation and qualitative studies into this field; (2) an exploration of the broad impact of treatment and (3) the possibility that epilepsy is a barrier to care provision.

Recognition and management of critical illness by midwives: implications for service provision

JOURNAL OF NURSING MANAGEMENT, Issue 3 2007
ENB 100, PGDipHE, SUZANNE BENCH RGN
Aim, The aim of this study was to explore midwives' recognition and management of critical illness in obstetric women in order to inform service provision. Background, Critical illness is not confined to Intensive Care. Limited published work was located examining factors affecting critical care provision by midwives. Methods, A multi-method design incorporating a paper and pencil simulation (n = 11) and in-depth interviewing (n = 5) was conducted with midwives from a large London National Health Service Trust. This study details and discusses the findings. Results, Findings indicated that frequency and type of critical illness experience impact upon midwives' critical care knowledge and skills. Midwives, especially those who were more junior, expressed anxiety regarding this aspect of practice, and considered the support of senior midwives, medical and nursing staff as crucial to effective client management. Conclusion, This study has yielded important insights into midwives' management of critical illness. Possible mechanisms to enhance the quality of service provision, and midwife support in this area are highlighted. [source]
