Optimal Resource Scheduler for LTE A based Networks

Long Term Evolution (LTE) may be a commonplace for prime rate radio transmission for cellular telephone and knowledge terminal. It is a complex technology that provides an accumulated network capability and speed by employing a totally special wireless interface beside the counter work enhancements. In the proposed method we deal with the setback of bandwidth administration in LTE-A systems and suggest valuable and profitable solutions to improve the quality of support in these networks. This paper presents an Optimal Resource Schedule which enhances the system throughput of LTE A based networks

Limited Spectrum

Device-to-Device (D2D) communications, which enable direct communication between nearby user devices over the licensed spectrum, have been considered a key technique to improve spectral efficiency and system throughput in cellular networks (CNs). However, the limited spectrum resources cannot be sufficient to support more cellular users (CUs) and D2D users to meet the growth of the traffic data in future wireless networks. Therefore, Long-Term Evolution-Unlicensed (LTE-U) and D2D-Unlicensed (D2D-U) technologies have been proposed to further enhance system capacity by extending the CUs and D2D users on the unlicensed spectrum for communications. In this paper, we consider an LTE network where the CUs and D2D users are allowed to share the unlicensed spectrum with Wi-Fi users. To maximize the sum rate of all users while guaranteeing each user’s quality of service (QoS), we jointly consider user access and resource allocation. To tackle the formulated problem, we propose a matching-iteration-based joint user access and resource allocation algorithm. Simulation results show that the proposed algorithm can significantly improve system throughput compared to the other benchmark algorithms.

Electroencephalogram Eeg

In the health-care system, parameters of patients such as Electroencephalogram (EEG), Electrocardiogram (ECG), Electromyogram (EMG), Glucose, Blood pressure, motion, etc. are monitored in real-time that assist doctors to timely detect and treat unexpected risks of patients. Thus, it is critical for collected sensor data seamlessly roaming between various types of wireless transmission networks such as Personal Area Network (PAN), Wireless Fidelity (WiFi), Long Term Evolution (LTE). Moreover, congestion carrier frequency between multiple close-by PANs can cause high packet drop rates and useless energy consumption of sensors. From above reasons, we proposed a protocol for PAN-gateway to integrate many wireless communication standards (typically ZigBee, WiFi, LTE) and an optimal control network algorithm for Quality of Service (QoS). Flows of sensor data are seamlessly transmitted through many wireless interface standards in order to achieved the best average data rate; sensor energy used effectively and fairness/priority between many users.

Abstract Purpose: This article addresses several intervention approaches that aim to improve life for individuals with severe aphasia. Because severe aphasia significantly compromises language, often for the long term, recommended approaches focus on additional domains that affect quality of life. Treatments are discussed that involve increasing participation in personally relevant life situations, enhancing environmental support for communication and participation, and improving communicative confidence. Methods: Interventions that have been suggested in the aphasia literature as particularly appropriate for people with severe aphasia include training in total communication, training of communication partners, and activity specific training. Conclusion: Several intervention approaches can be implemented to enhance life with severe aphasia.

Change Policy

The organizational structure of long-term care (LTC) facilities often removes the rehab department from the interdisciplinary work culture, inhibiting the speech-language pathologist's (SLP's) communication with the facility administration and limiting the SLP's influence when implementing clinical programs. The SLP then is unable to change policy or monitor the actions of the care staff. When the SLP asks staff members to follow protocols not yet accepted by facility policy, staff may be unable to respond due to confusing or conflicting protocol. The SLP needs to involve members of the facility administration in the policy-making process in order to create successful clinical programs. The SLP must overcome communication barriers by understanding the needs of the administration to explain how staff compliance with clinical goals improves quality of care, regulatory compliance, and patient-family satisfaction, and has the potential to enhance revenue for the facility. By taking this approach, the SLP has a greater opportunity to increase safety, independence, and quality of life for patients who otherwise may not receive access to the appropriate services.
