In the future smart factories will satisfy the demand of highly customized products. Stationary and mobile cyber-physical systems (CPS), as part of smart factories will exchange various information. Most of that will happen wirelessly. Out of that reason, a concept for real-time wireless networking of mobile CPS based on LTE is presented in this paper. Through a combination of LTE with GPS and adaptive streaming schemes, a real-time capable wireless communication system seems possible. The paper specifies further the necessary and targeted technical requirements of industrial communication for mobile CPS. It concluded with methods to test, evaluate and validate the communication system.

In today’s world of ‘Data at Finger Tips’, sensors have become ubiquitous, their applications have become numerous and this data is required round the clock and on-thego. The data picked up by the sensors is delivered to end-user in real time by IoT and further utilised for real time reports, off-line analysis and data aggregation. This review paper focuses on the different types of IoT sensors used for monitoring of atmospheric parameters. Sensors aided by wireless networking are the backbone of nowcasting and prevailing trends at any given area. IoT sensors data combined with satellite data and operational models enhance accuracy and expedite weather predictions. IoT data enable validation and updating of atmospheric depression models. Comprehensive study of sensors has been carried out and consolidated in this paper for ready reference by all stakeholdersMeteorological department, pollution control board, Nondestructive testing and evaluation of corrosive elements in atmosphere, farmers and horticulturists, to name a few.

This paper describes some recent results of our quiescent prominence spectrometry program at the Mees Solar Observatory on Haleakala. The observations were made with the 25 cm coronagraph/coudé spectrograph system using a silicon vidicon detector. This detector consists of 500 contiguous channels covering approximately 6 or 80 Å, depending on the grating used. The instrument is interfaced to the Observatory’s PDP 11/45 computer system, and has the important advantages of wide spectral response, linearity and signal-averaging with real-time display. Its principal drawback is the relatively small target size. For the present work, the aperture was about 3″ × 5″. Absolute intensity calibrations were made by measuring quiet regions near sun center.

We have employed cryoelectron microscopy to visualize events that occur during the freeze-drying of artificial membranes by employing real time video capture techniques. Artificial membranes or liposomes which are spherical structures within internal aqueous space are stabilized by water which provides the driving force for spontaneous self-assembly of these structures. Previous assays of damage to these structures which are induced by freeze drying reveal that the two principal deleterious events that occur are 1) fusion of liposomes and 2) leakage of contents trapped within the liposome [1]. In the past the only way to access these events was to examine the liposomes following the dehydration event. This technique allows the event to be monitored in real time as the liposomes destabilize and as water is sublimed at cryo temperatures in the vacuum of the microscope. The method by which liposomes are compromised by freeze-drying are largely unknown. This technique has shown that cryo-protectants such as glycerol and carbohydrates are able to maintain liposomal structure throughout the drying process.
