A Comprehensive Study on Pedestrians' Evacuation
Human beings face threats because of unexpected happenings, which can be
avoided through an adequate crisis evacuation plan, which is vital to stop
wound and demise as its negative results. Consequently, different typical
evacuation pedestrians have been created. Moreover, through applied research,
these models for various applications, reproductions, and conditions have been
examined to present an operational model. Furthermore, new models have been
developed to cooperate with system evacuation in residential places in case of
unexpected events. This research has taken into account an inclusive and a
'systematic survey of pedestrian evacuation' to demonstrate models methods by
focusing on the applications' features, techniques, implications, and after
that gather them under various types, for example, classical models, hybridized
models, and generic model. The current analysis assists scholars in this field
of study to write their forthcoming papers about it, which can suggest a novel
structure to recent typical intelligent reproduction with novel features
Quality of life of road traffic injury survivors aged 15-44 years suffered from moderate and severe head injuries in Karachi, Pakistan
Background: Most of Road traffic injuries are predicted to be the third leading contributor to the global burden of disease by 2020 and patients end up into head injuries which leave devastating impacts on individual and society. Quality of Life After Brain Injury (QOLIBRI) is a specific tool that measures quality of life in head injury patients.Methods: This was a cross sectional study among 300 patients aged 15-45 years, attended emergency department of the Aga khan University Hospital. Structured questionnaire included demography, injury details, QOLIBRI, GOSE and WHO Disability Assessment Scale (WHODAS 12 items). Severity of injury was determined by Glasgow coma score of subjects reported in emergency department on admission. This was one time telephonic survey in which bidirectional data was collected from subjects about injury and outcome (QOLIBRI). To identify the determinants of QOL among RTI survivors with head injury multiple linear regressions was applied.Results: The mean QOL score for study sample was 69.86 ± (15.89. Most of the patients 210 (70%) were motorbike rider followed by four-wheelers 69 (23%). Mean age of RTI participants was 28.10 ± (7.68) years. The quality of life decreases with increase in severity of head injury by -697.32 (95% CI; -1006.44, -388.20).Conclusions: This study suggests severity of head injury, recovery time, surgery resulting from RTA, employment, family system and disability to have long term impact on QOL of RTI survivors
Network Qos architecture
There is huge growth in internet recently. This growth is started initially at slow rate with limited number of application, However as the time progresses the nehvork has expanded in term of users and applications, This expansion dictated a alteration and modification of the original protocol to enable higher Quality of service. This chapter provides tan over view about QoS requirement, architecture and mobility suppor
Mobility management enhancement in smart cities using software defined networks
Achieving sustainability in cities relies on effective mobility management (MM) that serves
current and future generations. It involves establishing an inclusive transportation system to
address many issues, like traffic congestion, air pollution, and greenhouse gas emissions. Beyond
environmental concerns, robust mobility management has social and economic advantages,
fostering improved access to vital services like healthcare, education, and employment. Softwaredefined networking (SDN) presents a viable solution for enhancing MM within networks. Unlike
traditional setups, SDN merges MM through a programmable control plane, streamlining network
configurations and enabling features like handover, load balancing, and quality of service (QoS).
The utilization of SDN technology extends to various facets of sustainable city networks,
encompassing areas like network security, performance optimization, big data processing, energy
efficiency, emergency management, carbon emissions reduction, intelligent services, and MM in
vehicular networks. Despite the advantages of SDN-based mobility management, it’s crucial to
acknowledge the challenges and limitations posed by traditional MM methods that SDN aims to
overcome. The paper explores SDN’s potential in sustainable cities, focusing on how it can
transform mobile device management, support various networking technologies, and evaluate the
impact of SDN methods on existing MM systems, considering factors like scalability and
compatibility. The paper asserts that SDN-based MM has substantial potential for promoting
sustainable urban development. By centralizing control, adapting to changing conditions, and
optimizing resource allocation, SDN can contribute to reduced energy consumption, lower carbon
emissions, and more efficient urban mobility. It emphasizes the importance of addressing potential drawbacks to ensure successful implementation in sustainable cities
