The safety of hydrogen storage is essential for the development fuel cell vehicles. A mathematical model a compressed tank established based on mass conservation equation, energy equation and real gas state. Using Matlab/Simulink platform, dual-zone lumped parameter model, which divides into zone wall zone, established. initial conditions MC Default method filling from SAE J2601 are utilized in...

After the Paris Agreement was signed in 2015, many countries worldwide focused on hydrogen economy, aiming for eco-friendly and renewable energy by moving away from existing carbon which has been primary source of global warming. Hydrogen is most common element Earth. As a light substance, can diffuse quickly; however, it also small risk explosion. Representative explosion accidents have includ...

The integration of segregated brain functional modules is a prerequisite for conscious awareness during wakeful rest. Here, we test the hypothesis that temporal integration, measured as long-term memory in the history of neural activity, is another important quality underlying conscious awareness. For this aim, we study the temporal memory of blood oxygen level-dependent signals across the huma...

In this work we devise a classification of mouse activity patterns based on accelerometer data using Detrended Fluctuation Analysis. We use two characteristic mouse behavioural states as benchmarks in this study: waking in free activity and slowwave sleep (SWS). In both situations we find roughly the same pattern: for short time intervals we observe high correlation in activity--a typical 1/f c...

Rats repeatedly ran through a sequence of spatial receptive fields of hippocampal CA1 place cells in a fixed temporal order. A novel combinatorial decoding method reveals that these neurons repeatedly fired in precisely this order in long sequences involving four or more cells during slow wave sleep (SWS) immediately following, but not preceding, the experience. The SWS sequences occurred inter...

Introduction Acquisition of alternative fueled vehicles (AFV) within the United States and the Department of Defense is mandated by Federal Legislation and Executive Order. Under these mandates, the Air Force is required to plan, program, purchase, and utilize alternative fueled vehicles and establish access to refueling facilities. The applicable Acts and Orders accomplish two main goals. Firs...

This paper examines accurate image depth determination in order to achieve accurate navigation. This is critical for Unmanned Aerial Vehicle or UAV aerial refueling and also space debris clearance operations. The theory behind image depth calculation is explained and then synthetic pixel data is manufactured in order to determine a 95% confidence interval on image depth under various errors con...

the capability to preserve human oocytes, blastocysts, ovarian tissue and spermatozoa is an important tool in human assisted reproductive techniques. this preservation allows patients undergoing chemotherapy or radiotherapy to preserve their fertility, and helps to attain all benefits from the costly ovarian superovulation therapies prior to art. the primary goal in establishing an appropriate ...
