In this paper, we are presenting a bionic approach towards real-time systems research. Observing that a cell is a real-time computing, but also a producing, system, the work presented here explores the analogy between the real-time computer systems (and their management) and the molecular biology control systems. This paper is a further elaboration of the idea that the DNA is indeed a real-time system. It also gives insight into how knowledge obtained from the biological systems could lead to further evolution and improvement of the human-made complex real-time systems.

This research investigates the outcome of using a computer-based therapy program in ambulatory training for post-acute stroke patients. Patients with stroke typically suffer dysfunctions that impair the complex set of motions involved in walking. The limited amount of therapy and resources offered by the current health care system do not provide the frequency and intensity of training needed for functional recovery of the walking skills in patients following stroke assaults. This non-traditional intervention research technique therefore sought to develop an alternative method capable of providing the frequency and intensity needed for improving the walking skills in post-acute stroke patients. The work also attempted to show how skills gained in virtual environments transfer to the real world. The work employed the case study method to report the results observed from four post-acute stroke patients who trained on the non-traditional intervention program for about half an hour per day, five days a week, for a period of four consecutive weeks at the out-patient department of the Sir John Golding Rehabilitation Center. The patients performed a computer-based painting exercise with their hemiplegic legs using a head-mounted display, and their gait variables were recorded and analyzed to determine the usefulness of the program in ambulatory training for post-acute stroke patients. A follow up examination conducted one week after the intervention sought to determine whether the patients could perform the skills learned on the computer-based intervention program in the real world. The results of the research showed that all the patients improved on their gait parameters and could walk better. An observational gait analysis conducted one week post-intervention showed that the skills gained in the virtual environment transferred to real-world conditions. The study contributes to the current effort to provide wider access to therapeutic intervention techniques using computer technology.

The design of an efficient, long operation near space vehicle will require the effort of researchers in various disciplines. With contributions from aerospace, mechanical and electrical engineers, this goal can be certainly attainable. Aerospace engineers can simulate and design the aerodynamic properties of the vehicle. Mechanical engineers can aid in this process, but their responsibility lies in the mechanics of the propulsion system and any mechanical actuation that needs to be performed in the payload or vehicle. The electrical engineer's primary responsibility is with the power management system. Although this is their primary responsibility, the electrical engineer can also have responsibilities in the propulsion system, controller and communication system. This paper highlights the major tasks required to design a near space vehicle and focuses on the responsibilities of the electrical engineer during the design process.

Miniaturized pressure sensors attached to catheters have numerous applications in the biomedical and life science fields including the monitoring of arterial, ventricular, intracranial and intraocular pressures. Recent advances in MEMS (microelectromechanical systems) technology and its associated fabrication processes, such as DRIE (deep reactive ion etching), have allowed for further miniaturization of these devices, expanding the application landscape to include small animal models and new human applications. One such human application is the wireless measurement of radial arterial blood pressure (BP). The goal of this research program is to produce a truly portable wireless radial arterial monitoring system using a custom-designed ultra-miniature pressure sensor appropriately sized to fit within the tip of a 1-French catheter (333 micron), so that convenient in-vivo measurements of BP are possible. The proposed system consists of two assemblies. The sensor, catheter, and wristband containing the battery and telemetry circuit form one assembly and the portable wireless PDA-sized transceiver module forms the other. This paper reports on the custom miniature MEMS pressure sensor developed for this application.

Consider the problem of tracking a survey's cost and progress. Management must monitor the costs of the survey on a routine basis to ensure that actual expenditures do not exceed the budgeted dollar amounts. Management must monitor the progress of the survey on a routine basis to ensure that work was completed on time. This paper discussed the automated reporting environment by which cost and progress can be monitored. Given that seven systems must be polled for the information and ten reports must be developed, it becomes difficult for the programmer to comprehend where the data originates for the cells in the reports. A somewhat simple means were developed to show the cell relationships with-in reports and between reports using a tree structure. Having the cell relationships in the requirements documentation eases the programming burden as well as tracing the final product back to the requirements and specifications.

The electric vehicle concept is gaining momentum in competing with the internal combustion (IC) based vehicle due to rising fuel prices and demands for alternative energy vehicles. Particularly, fuel cell electric vehicles are gaining attention as a real alternative to the pure IC engine vehicle. Because of this emerging technology, considerable research into the configurations of these fuel cell electric vehicle systems is being considered. The main components include the main power supply, an energy storage system to increase the power density of the system, a DC-DC converter to supply energy to the energy storage system or vehicle accessories and the motor drive. Because these systems are expensive and potentially unsafe when testing new algorithms, there is a need for a static power system test facility. This test facility will include any or all of the components of the actual fuel cell electric vehicle system and can be used to simulate behavior of the system and optimize it. This paper presents such a system that was simulated using MATLABreg Simulink and implemented in hardware for testing of emerging electric vehicle systems at the University of Alabama's Electro-Mechanical Systems Laboratory (EMSyL).

Class AB amplifier stages are commonly used to conserve power in radio transmitters. In this paper, a Class AB amplifier stage is investigated for use in radio receivers to reduce power consumption. In this, a novel superlinear three-terminal transistor consisting of an NMOS transistor in parallel with a PMOS transistor is used to improve Class AB linearity to a level approaching Class A performance. Optimum transistor bias conditions for the linearized Class AB receiver stage are also presented. Measured and simulated results at 1 GHz show supply current reduction of approximately 40 percent and 4 dB improvement in third order intercept point using linearization. Finally, simulations of an improved Class AB design show third order output intercept better than a corresponding Class A stage and show more than 50 percent reduction in power consumption.
