Abstract:
The performance of portable ultrasound systems is affected by the excessive heat generated by amplifiers, thereby reducing the sensitivity and resolution of the transducer devices used in ultrasound systems. Therefore, the amplifier needs to generate low amounts of heat to stabilize portable ultrasound systems. To properly control the amplifier, the related bias circuit must provide proper DC bias voltages for long time periods in ultrasound systems. To this end, a stacked transistor bias circuit was proposed to achieve a relatively constant amplifier performance irrespective of temperature variance without any cooling systems as the portable ultrasound system structure is limited. To prove the proposed concept, the performance of the gain and DC current consumption at different experimental times was measured and compared to a developed class-B amplifier with different bias circuits. The amplifier with the stacked transistor bias circuit outperformed with regard to the gain and DC current variance versus time (−0.72 dB and 0.065 A, respectively) compared to the amplifier with a typical resistor divider bias circuit (−5.27 dB and 0.237 A, respectively) after a certain time (5 min). Consequently, the proposed stacked transistor bias circuit is a useful electronic device for portable ultrasound systems with limited structure sizes because of its relatively low gain and DC current variance with respect to time.

Abstract:
INTRODUCTION: A high percentage of post-stroke patients have permanent aftermathsdespite conventional rehabilitation. Circuit class training offers an efficient way to achieve structured practice of task-related activities during stroke rehabilitation. Aquatic therapy is another therapeutic approach that offers a great variety of options to be a highly dynamic environment, which helps to improving functionality and recover quality of life and independence in people with disabilities. OBJECTIVE: To develop a protocol for a randomized controlled trial. METHODS: Forty participants will be randomized in two groups: aquatic circuit class training (ACCT) and land circuit class training (LCCT). In both groups, the intervention will be a 7-week class therapy, 3-times weekly, giving a total of 20 sessions, 60 minutes each. Blinded assessors will conduct assessments, using standardized tools: baseline, post-intervention, and 20 days follow-up for the effectiveness of the therapy in terms of gait, balance and upper limb motor function. RESULTS/CONCLUSION: This trial will examine the immediate and medium term effect of an ACCT program as compared to a LCCT program in people with stroke. It has the potential to identify interventions that may improve rehabilitation of these patients. Both CCT programs are based in International Classification of Function, Disability and Health model with activities aimed at impairment, activity and participation levels.

Abstract:
Philosophiae Doctor - PhD (Physiotherapy)
Stroke is a debilitating medical and neurological condition. It is the leading cause of adult disability worldwide. Disability from stroke covers the three key classifications of the WHO-ICF framework on human function centred on health and health related issues, implying that the disability in stroke involve structural and activity limitations to participation restriction. Rehabilitation remains the hallmark of managing the plethora of neurological deficits accompanying stroke. Currently, the key advocacy in neuroscientific studies for stroke rehabilitation is that therapy should be directed towards task specificity. Task Specific Training most recently, the form of Circuit Class Therapy and the intensity of multiple repetition of the task has been identified as physiological mechanisms behind sustained motor learning following stroke.Circuit Class Therapy (CCT) is a form of Task Specific Training (TST) that involves the practice of structuring tasks in a circuit or series of workstations. It offers the patient the ability to practice multiple tasks in a conducive environmental because of its three key features of utilisation of different workstations that allow people to practice intensively in a meaningful and progressive way to suit their respective needs; the efficient utilisation of therapists'/trainees' time; and the group dynamics such as peer support and social support. Although these features are attainable following CCT challenges remain in selecting the most efficient intensity that could produce these benefits in stroke survivors. This study investigated the effectiveness of differing intensities of CCT in the rehabilitation of stroke survivors using the ICF framework to guide patients� response assessments after training.

Abstract:
There is increasing evidence that stroke survivors benefit from the provision of intensive, task-specific therapy in the rehabilitation of motor function. Providing such therapy to a number of stroke survivors in a group setting (know as circuit class therapy) has been proposed as an alternative model of physiotherapy service delivery within the inpatient rehabilitation setting. This study investigated the effectiveness and feasibility of circuit class therapy, as compared to the standard practice of one-to-one therapy sessions, within a representative sample of stroke survivors receiving inpatient rehabilitation.

Abstract:
MV (Medium Voltage) controller lineup electrical protection is crucial in protecting the equipment from large scale damage upon the occurrence of an electrical fault, reducing the time to restore power, thereby minimizing the impact to liquids pipelines operation. The paper discusses typical electrical failure modes that may occur in MV controller lineups, and demonstrates practical relaying engineering techniques that enable fast and effective fault clearing. Electrical faults in the MV controller lineup are often arcing type, commonly involve ground. Mitigating arc hazards in MV Class E2 controller lineups has traditionally been challenging without sacrificing the protection selectivity. As the paper demonstrates, a relaying scheme with the combined use of high-speed light-sensing and overcurrent detection will effectively mitigate the incident energy, while maintaining the protection selectivity for non-arcing overcurrent events. For new MV controller lineups, in addition to the “high-speed light detection and fault interruption”, zone-selective interlocking (ZSI) can also be a practical solution in improving relay protection speed, thus reduce the chance of severe arc flash occurrences. ZSI is particularly effective for fault occurrences on the line side of the phase CTs, busways or main incoming circuits. The ZSI scheme can be implemented on both Class E2 and circuit breaker (VCB) type MV controller lineups, however, with slightly different trip logic due to the limited fault clearing capability of the contactor. Although there are multiple contributing factors, the direct causes of electrical failures in MV controller lineup are commonly related to improper power cable installation and handling, potentially leading to premature insulation breakdown due mainly to the proximity effect and/or partial discharge. Inadequate cable separation and prolonged fault trip delay can increase the possibility of arcing fault occurrence. This can usually be mitigated through appropriate cable spacing, adequate conductor insulation, and optimized fault detection schemes. The paper provides overviews of the mechanisms of proximity effect and partial discharge propagation, and the modern relaying approaches for accurate fault type discrimination and facilitating fast fault interruption. Two case studies are provided in the paper as an aid in understanding the electrical fault mechanism originated from cable insulation failure, demonstrating the incident energy reduction before and after the implementation of high-speed light detection and fault interruption solutions on an existing MV controller lineup.
