Baby Near is the project created to assist parents to monitor their children in open or closed environments, mainly with crowds, such as supermarkets, malls, playgrounds, among others. The prototype consists of two ends that communicate with each other by Bluetooth, one with a smartphone and another with an Arduino. If the distance between them is highier than the one set by the parents, the cellphone device emits sounds, vibrations and changes on screen that alert the parent that the distance has been exceeded. In addition, the end of the Arduino also has a short distance electronic tag that can be used by parents to insert information relevant to the child's finder. In this way, the system brings to the parents more speed in the detection of an emergency situation due to the increase of the distance of the child.

Now a day every information is stored and shared on the cloud. And so the medical record especially Personal Health Record (PHR) is an important part of health information exchange, that is need to be stored at cloud servers. But there are various privacy problems as personal health information could be discovered to unauthorized people. That need guarantee of the patient control over to their own PHRs, in this method encryption of the PHRs is done before the storage on cloud. But still issues like risks of privacy, efficiency in key administration, flexible access and efficient user administration, have still remained the important challenge toward achieving better, cryptography imposed data access control. In this research development, we develop a mechanism for control of data access to PHRs stored in cloud servers. To achieve this efficient and modular data access control for PHRs, we provide encryption approach for the encryption to each PHR file. For this system method already tried to focus on the multiple data ownership scheme also dividing the users into security domains that highly reduce the key management complication for owners and users. Here the system takes patient privacy as serious issue and guaranteed it by exploiting multi-authority Encryption. Our main aim is not only privacy but also systems scheme try to enable modification of access policies or file attributes, and break-glass access under emergency situations. Our proposed scheme shows Extensive analysis and experimental results are presented for security and efficiency of PHR.

AKARI and Spinning Dust: A look at microwave dust emission via the Infrared Aaron C. Bell's Master's Course Thesis ABSTRACT: Rapidly spinning dust particles having a permanent electric dipole moment have been shown to be a likely carrier of the anomalous microwave emission (AME), a continuous excess of microwave flux in the 10 to 90 GHz range. Small grains, possibly polycyclic aromatic hydrocarbons (PAHs), are a leading suspect. In the absence of a definitive answer on the presence of PAHs or their role as an AME carrier, some predictions have been made as to the implications of spinning PAH emission. Due to the overlap between the CMB and the galactic foreground, this topic is requiring cosmologists to consider the ISM with more care. ISM astronomers are also needing to consider the contribution of cosmological radiation to large-scale dust investigations. We present data from AKARI/Infrared Camera (IRC) due to the effective PAH band coverage of its 9 micron survey to investigate their role within the 98 AME candidate regions identified by Planck Collaboration et al. (2014). We supplement AKARI data with the four Infrared Astronomical Satellite (IRAS) all-sky maps and complement with the Planck High Frequency Instrument (HFI) bands at 857 and 545 GHz to constrain the full dust thermal spectral energy distribution (SED). We sample the average spectral energy distributions (SEDs) all 98 regions. We utilize all 7 AKARI photometric bands, as well as the 4 IRAS bands and 2 HFI. We carry out a modified blackbody fitting, and estimate the optical depth of thermal dust at 250 micron, and compare this to AME parameters. We also show plots of each band's average intensity for all 98 regions vs. AME parameters. We find a positive trend between the optical depth and AME. In the band-by-band comparison the AKARI 9 micron intensity shows a weaker trend with AME. In general, the MIR correlates less strongly with AME than the FIR. The optical depth vs. AME trend improves slightly when looking only at significant AME regions. Scaling the IR intensities by the ISRF strength G0 does not improve the correlations. A slightly positive trend found previously among 10 AME regions vs. AME significance is revisited, using the larger sample of 98. However the trend does not hold up to the full data set. We cannot offer strong support of a spinning dust model. The results highlight the need for full dust SED modelling, and for a better understanding of the role that magnetic dipole emission from dust grains could play in producing the AME.
