The use of omega-3 fatty acids for depression treatment is of considerable interest, in part due to the inadequate efficacy and tolerability of standard antidepressant medications. Although several metaanalyses have reported positive outcomes for omega-3 fatty acid treatment of depression, the metaanalysis by Bloch and Hannestad suggests no significant(More)
This paper describes a design approach to include and optimize Java based cryptographic applications into resource limited embedded devices.For easy prototyping and to be platform independent, the security applications are first developed in Java. Two Java cryptographic libraries, the Bouncy Castle API and the IAIK API are ported to a real embedded device(More)
This paper overviews nonlinear dynamics of switching power converters which are common objects in dynamical system theory and power electronics. First, complex dynamics of single switching power converters is discussed. Their nonlinear switching can cause rich chaotic and bifurcation phenomena including complicated superstable periodic behavior in(More)
In the development of medical skill training systems, the efficiency of the system and the provision of quantitative feedback information to the trainee are very important. Furthermore, usage of the simulated operation platform should be as realistic as possible. In order to satisfy these requirements, we developed a robot to be used for airway management(More)
SUMMARY This paper studies rich superstable phenomena in a nonau-tonomous piecewise constant circuit including one impulsive switch. Since the vector field of circuit equation is piecewise constant, embedded return map is piecewise linear and can be described explicitly in principle. As parameters vary the map can have infinite extrema with one flat(More)
SUMMARY This paper studies a chaotic spiking oscillator consisting of two capacitors, two voltage-controlled current sources of signum shape and one impulsive switch. The vector field of circuit equation is piecewise constant and embedded return map is piecewise linear. Using the map parameter condition for chaos generation is given. Using a simple test(More)
Airway management is a basic skill for emergency rescue. The operation of the bag valve mask (BVM) is also a key process. The BVM is used not only to provide oxygen but also to detect if the tracheal tube is inserted in the trachea or bronchus. Currently, there are many training platforms designed for training medical staff. Most of them can provide(More)
