    The world of the 21st century will be swifter, more complex, and more connected. Solutions to tomorrow's problems will require the contributions of many disciplines and points of view. There will be tremendous challenges and opportunities for engineers-all engineers-but especially those in the field of bioengineering. Consider the problem the nation now faces with respect to the health care system... View full abstract»

    How much right should an inventor have to control the future? That was the question decided by the United States Supreme Court in the famous 1853 case of Samuel Morse and his telegraph, and the answer the Court gave then is still the law today. This rule of law, now more than 140 years old, says that no matter how great an invention may be, there comes a point where a court will step in and say th... View full abstract»

    Several paradigms or strategies-some of them introduced here-were applied to point out that the EEG serves as a functionally relevant signal (or operator) in various frequency channels. These can be brought to resonant behavior depending on functional brain states. The authors emphasize that the EEG-operators are functionally significant if 1-4 Hz, 4-7 Hz, 8-13 Hz, or 40 Hz activities can be broug... View full abstract»

    The authors review recent efforts to design stimulus waveforms for selective electrical stimulation of the nervous system. Two types of selectivity are considered. Fiber diameter selectivity refers to the ability to activate one group of nerve fibers having a common diameter without activating nerve fibers having different diameters. Spatial selectivity refers to the ability to activate nerve fibe... View full abstract»

    Nurse scheduling is a difficult, multifaceted problem. Here, the authors have presented the efficiency of Constraint Programming for solving this problem. The results obtained are very satisfactory for response time and for flexibility. The advantages of implementing this method are multiple: 1) it saves much time for the head nurse in the generation of schedules (the authors met head nurses for w... View full abstract»

  • Magnetic fields and cancer

    The massive body of epidemiological data searching for a relationship between magnetic field exposure and the incidence and development of cancer tells one that the presumably exposed population has essentially the same health characteristics as the population as a whole. Some comfort may be found in the fact that epidemiology has not revealed any large or unusual associations. But, the cost to so... View full abstract»

    In ophthalmologic diagnostics well-defined light stimuli are used to study the visual system. Sensor arrays are used in applications where the signal-to-noise ratio is very low or where the spatial structure of the signal is of interest. Since the signal-to-noise ratio can be exponentially increased with the designed function it can be assumed, that the reliability of signal detection will also si... View full abstract»

  • Stationarity of the EEG series

    The authors introduce a routine for the analysis of stationarity, which is based on the weak stationarity criteria. From the application of the weak stationarity criteria, one see that only in some cases or in some epochs of a series will the information obtained from these algorithms be reliable. Therefore, one can only obtain dynamic information in those cases. As a complement to this finding, t... View full abstract»

    Several major suppliers of material used in medical devices, including Dow Chemical, Dow Corning and DuPont have recently decided not to sell these materials to device manufacturers. Other material suppliers have done the same or are reviewing their policies on this matter. Some of the biomaterials that have been or may soon become unavailable for medical device manufacturing include polyurethane ... View full abstract»

    This research has shown that features extracted from color skin tumor images by computer vision methods can be reliable discriminators of malignant tumors from benign ones. Reliability was demonstrated by the monotonically increasing success ratios with increasing training set size and by the small standard deviations from the mean success rates. An average success rate of 70 percent in diagnosing... View full abstract»

    Engineering today is the backbone for support and advancement of the environment to keep the United States a world leader in the realm of health care. Over the past year, the expense for health care has astoundingly risen by over $100 billion. Hence, many politicians have proposed several ideas for a reform policy that will cut spending on health care, yet improve it at the same time. The Clinton ... View full abstract»

    Power wheelchair controllers become more sophisticated as motor control and human/machine interaction research progresses. The result of this increasing sophistication is that more people are provided with independent mobility. The challenge for engineering is to provide safe and effective mobility in a dynamic environment. Fortunately, many of the control methods outlined in here make that goal a... View full abstract»

    Extensive epidemiological and laboratory research has been conducted over the last 15 years on the biological and health consequences of exposure to ELF EMFs. Some epidemiological studies have found weak associations between exposure to power-frequency EMFs and some forms of cancer, such as leukemia; while other studies have failed to find such associations. The primary limitation with most epidem... View full abstract»

    The study demonstrated that computer-based waveform subtraction is a viable approach for the accurate determination of the refractory periods (RPs) of the neurally-evoked compound electromyograms (ncEMGs) and the refraction of neuromuscular transmission. Computer-based waveform subtraction can easily extract the R2 waveform from the complex ncEMGs and calculate accurate R2/R1 ratios. The method is... View full abstract»
