Study on RSS/AOA hybrid localization in life detection in huge disaster situation

AbstractThe search for alien life is hard because we do not know what signatures are unique to life. We show why complex molecules found in high abundance are universal biosignatures and demonstrate the first intrinsic experimentally tractable measure of molecular complexity, called the molecular assembly index (MA). To do this we calculate the complexity of several million molecules and validate that their complexity can be experimentally determined by mass spectrometry. This approach allows us to identify molecular biosignatures from a set of diverse samples from around the world, outer space, and the laboratory, demonstrating it is possible to build a life detection experiment based on MA that could be deployed to extraterrestrial locations, and used as a complexity scale to quantify constraints needed to direct prebiotically plausible processes in the laboratory. Such an approach is vital for finding life elsewhere in the universe or creating de-novo life in the lab.

Respiration Motion

In practical situations such as hostage rescue, earthquake and other similar events, the ultra-wideband (UWB) life-detection radar echo response from the respiration motion of the trapped person is always quasi-/non-periodic in respiration frequency or very weak in respiration amplitude, which can be called quasi-static vital sign. Although it is an extremely difficult task, considering the economic cost, the detection ability of the traditional UWB life-detection radars with only a pair of transceiver antennas is desired to be enhanced for locating the quasi-static trapped human being. This article proposes two different detection methods for quasi-static trapped human beings through the single/multiple observation points, which corresponds to the single-/multi-station radar operating mode, respectively. Proof-of-principle experiments were carried out by our designed radar prototypes, validating the effectiveness of the proposed methods.

To Receive

<span>Indonesia is a country located on top of some tectonic plates that bring potential natural disasters. Disaster management system is considered essential in controlling the situation in the site both before and after the disaster takes place. In disaster situation, the government and society are involved in a volunteer team in order to help minimize victims and support survivors. However, the volunteering activities are often hindered since there are problems in the disaster site. One of the problems is late responses due to poor coordination among volunteers that drives the delay in disaster relief. Therefore, it is necessary to have an application that maps the positions of volunteers in a disaster site, so that the disaster management coordinator can disseminate volunteers to disaster areas based on needs. The purpose of the study is to propose an application called ‘MyMapVolunteers’ that effectively and efficiently detects the position of the volunteers in order to improve disaster management service. In this case, real time and location based service technology will able to detect the position of each volunteer. ‘MyMapVolunteers’ is composed of two platforms, which are mobile and web applications. Mobile platform is an application that uses GPS function provided by the smartphone to find the volunteers’ location coordinates and then send the data of the location automatically and manually. The web platform is used to receive volunteers’ location data and to present them in google map, therefore disaster management coordinator can monitor the positions of and search for volunteers faster.</span>

The Relationship

The Lapindo Mud is a natural disaster occurred 13 years ago and still erupts today. Of course this disaster affects the people who live around it. The people who are the victims of the mud disaster is still survive. Therefore, it is important to understand how this people could survive in this disaster situation. Thus, the purpose of this quantitative, correlational study is to investigate the relationship between gratitude and psychological well-being for the resident around Lapindo mudflow. This research used quantitative method with survey. The scale used was The Gratitude Questionnaire-Six Item Form (GQ-6) developed by McCullough to measured the level of gratitude and Javanese Psychological Well-being Scale developed by Palupi to measured psychological well-being. The result showed that there is relationship between gratitude and psychological well-being in the population/resident around Lapindo mudflow.
