concerns related to climate change and security of energy supply is pushing various countries to make strategic energy planning decisions. in this regard, energy system modelling is an appropriate method to find out the utilization of current declining non-renewable energy resources and other possible scenarios. consequently, it is available to consider various aspects of energy system decision...

size reduction of high energy materials such as 1, 3, 5, 7-tetranitro- 1, 3, 5, 7-tetraaza cyclooctane (hmx) has considerable influences on improving their explosive characteristics. in this study, nanosized hmx par­ticles were produced using ultrasonically reprecipitation method by applying water as a safe and accessible antisolvent instead of unsafe conventional methods. sem photographs revea...

Pulsating and explosive time profiles of mm-wave solar bursts observed at Metsähovi are examined in terms of the energy release in a single current-carrying loop. We suppose that the electric current in the loop is driven by photospheric convective flows. The flare occurs due to flute instability provoking the penetration of partially ionized plasma from the chromosphere or prominence into the ...

Individual heterogeneity is a key characteristic of many real-world systems, from organisms to humans. However its role in determining the system’s collective dynamics is typically not well understood. Here we study how individual heterogeneity impacts the system network dynamics by comparing linking mechanisms that favor similar or dissimilar individuals. We find that this heterogeneity-based ...

The introduction of inductive storage/opening switCh pulse forming networks as an operational reality in the llUllti-megajoule, sub-microsecond range, makes possible the design and operation of very large high power systems at modest cost.l• 2 The operational simplicity and economy of the pulse shortening system shifts the emphasis from opening switches to that of finding suitably simple, highl...

A 1MV Tandem Proton Accelerator is being developed for the industrial applications such as high-energy implantation and explosive detection. The proton accelerator consists of a 10mA negative hydrogen ion source, two Einzel lens, accelerating tubes, a gas stripper, a 1MV 30mA Cockroft-Walton high voltage power supply, vacuum pumping system, and a high pressure insulating gas system. The large c...

This paper reports the LIBS studies on elemental composition detection and identification by employing a femtosecond (fs) fiber laser. High quality LIBS spectra were obtained in air using near-infrared fs fiber laser coupled with a broadband high sensitivity spectrometer without gating control. Specific ion and neutral emission lines of different materials have been characterized by line scanni...

Explosive collective phenomena have attracted much attention since the discovery of an explosive percolation transition. In this Letter, we demonstrate how an explosive transition shows up in the synchronization of scale-free networks by incorporating a microscopic correlation between the structural and the dynamical properties of the system. The characteristics of the explosive transition are ...

How mechanical and biological processes are coordinated across cells, tissues, and organs to produce complex traits is a key question in biology. Cardamine hirsuta, a relative of Arabidopsis thaliana, uses an explosive mechanism to disperse its seeds. We show that this trait evolved through morphomechanical innovations at different spatial scales. At the organ scale, tension within the fruit wa...
