Abstract: In the modern society, the concept of “efficiency” has been emphasized in numerous areas, and is especially critical in discussing the transfer-efficiency of the energy generated. If the concept is not being emphasized in, it is likely that numerous severe consequences would be resulted, for instance, the kinetic energy received by drivers might be massive and even ultimately terminate their lives. The paper targets the factor that affects most in the inertial energy transfer of Newton’s Cradle used in the experiment as a subject, getting the information of the actual energy transfer efficiency within the cradle through recording video and locating the position of the balls on a graph paper, analysing the rebounded height level data quantitatively, obtaining the relevant parameters of Cradle such as the mass of the balls and the length of the strings as well as the diameter of the balls through direct measurement. Then, the calculation of the energy loss during the collision would be made and the regression model would be constructed. After that, taking advantage of the hypothesis testing method to testify the significance of the relevant parameter within the Newton’s Cradle model. Next, further modifications, which allows a simulation of the energy transfer efficiency of colliding process to be conducted, could be made and the most influencing factor for energy transferring would be revealed and thus find link with the car accident in the method of reducing the damage caused during the incidents.

Abstract: The sterile insect technique (SIT) is an environment-friendly blighter management technique with application within the area-wide integrated management of key pests, together with the suppression or elimination of introduced populations and therefore the exclusion of recent introductions. Procreative sterility is often evoked by radiation, a convenient and consistent technique that maintains an inexpensive degree of aggressiveness within the discharged insects. The price and effectiveness of an effective program integration of the SIT rely on the balance between sterility and aggressiveness, but it seems that current operational programs with an associate SIT element aren't achieving an associated, applicable balance. In this paper, we will discuss how to improve the sterilization method as well as a simple model and procedure for determining the optimum dose. The work in the gift was focused on an association analysis of the electromagnetic wave technique for insect sterilization as a risk issue. Discharge of enormous numbers of gamma-radiated male flies over the complete island caused concern regarding sterilization as an attainable technique for the dominant insects' public health. Several studies on the sterilization of varied insect vectors of sickness have been conducted since then. The study's goal was to check if electromagnetic waves were an efficient insect management mechanism. Insect sterilization is commonly used to create safe environments for fruit homes, manage blighters, and avoid livestock health issues. The sterilization insect technique entails mass-rearing of the target species, sterilization of the male, and unharnessing in sufficient numbers to equal wild male flies in the natural environment. It's species-specific, with no results for any of the 'non-target' species.
