Since monitoring one’s ovulation in an accurate manner is significant to the physiological health of women during the reproductive period, it’s better to combine family healthcare and smart home devices to work out feasible ways of ovulation monitoring. A study found that the value of LH(luteinizing hormone) in women’s urine was significantly correlated with ovulation. Therefore, by measuring the peak of LH, the ovulation status of women could be accurately monitored. In this study, a monitoring system was designed to determine ovulation status by detecting LH (luteinizing hormone) value in female urine. This monitoring system was integrated with the household toilet to realize the real-time and accurate monitoring of ovulation status of female individual. In the aspect of hardware, the device appearance, the detection device structure and the micro-control electronic device were designed by applying the Internet of things technology, to help women obtain ovulation information in a convenient and stable manner. Whereas in the aspect of software, the author analyzed the monitoring data based on computer algorithm, developed mobile application, and established the individual longitudinal database with multiple detection values as background data, so as to predict ovulation activity and evaluate ovulation patterns. It would help women track their ovulation more accurately, prevent and indicate gynecological reproductive diseases, and can serve as a supplementary basis for medical diagnosis and treatment results.

In order to improve the flawed method of testing and verifying of the MEMS security system on small caliber bullet, a mini-Hopkinson impact system is built, which is more suitable for MEMS security systems rapid verification test. This system is based on the original Hopkinson pressure bar system, which can easily control the speed of the bullets by firing them with electromagnetic coils. By adjusting the launch series and the charge voltage value, the system can output a numerically adjustable acceleration, whose maximum value can be as high as 45000g. The system just costs a few minutes for a test. Through the test of the impact system we can found that compared to the traditional high load test method, it is more convenient to use this system. It can offer a high-load impact, and the test frequency is higher. The result of the test is more accurate and easier to be monitored in real-time. This mini-Hopkinson impact system can test the threshold determination module effectively. Besides, it can also test other MEMS modules of Small caliber ammunition like MEMS gyroscope, etc.

The process of collecting preferences from users is fundamental during the normal operational life of a recommender system. The preference elicitation strategy can affect both the “user utility” (how well the system can make good recommendations to the new user who is undergoing the elicitation process) and the “system utility” (how well the system can provide good recommendations to all users, given what it learns from the new users). Not only do recommender systems need to gather information from users; they also need this information to be reliable and noiseless, as inconsistencies in user preferences limit prediction accuracy…

If virtual worlds are to fulfil their promise as stages for entertainment, education and artistic endeavour, with who or what shall we people them? And what methods are available to us to design the dramatic elements of these worlds? Both drama and virtual realities are multi-modal experiences. By drawing on crossover research between the disciplines of theatre, HCI and system design, we put forward an innovative basic framework for the design of virtual worlds – an envisionment. This paper will examine the nature of interactive experience in relation to user viewpoint and identity, and will develop a frame of reference for the structure and composition of virtual worlds in dramatic terms: location and environment, content, actions, time-scale, events, metaphysical structures and characters. We shall draw attention to the significance of constraints and potentials to envisionment and to techniques drawn from object-oriented analysis and design to model them. We hope that this paper will stimulate a discussion of the issues raised and future directions for research.
