This article applies experimental methods in the laboratory to determine the increase of soil density with explosive energy. The results show that soil moisture, explosive mass, and the distance between compacted soil and the explosion centre have influenced the compaction of the studying soil significantly.

In recent years with the explosion of research in artificial intelligence, deep learning models based on convolutional neural networks (CNNs) are one of the promising architectures for practical applications thanks to their reasonably good achievable accuracy. However, CNNs characterized by convolutional layers often have a large number of parameters and computational workload, leading to large energy consumption for training and network inference.

This paper describes the formulation of two polymer-bonded explosives based on RDX (hexahydro-1,3,5- trinitro-1,3,5-triazine) and fluoroelastomer binders by the water-slurry coating method. The fluoroelastomers are poly(VDF-HFP) (vinylidene fluoride-hexafluoropropene copolymer) and poly(VDF-CTFE) (vinylidene fluoride-chlorotrifluoroethylene copolymer). It has been observed that the impact sensitivity and the friction sensitivity of PBX samples were significantly lower than that of the single RDX.

This paper presents the results of research on the effects of various factors such as the main explosive content, the ratio and component of the binder to the characteristics (ignition temperature, impact sensitivity, chemical stability, brisance by Hess, detonation velocity and explosive strength) of polymer-bonded explosives (PBXs) based on hexogen and nitrocellulose.

The results showed a strong correlation between the load and the premixed mass, defined as the mass of the molten material in low void zones (void fraction < 0.75). The jet diameter and velocity that comprise the flow rate were the primary factors to determine the premixed mass and the load.

Electrical hazard, safety-toe shoes are nonconductive and will prevent the wearers’ feet from completing an electrical circuit to the ground. These shoes can protect against open circuits of up to 600 volts in dry conditions and should be used in conjunction with other insulating equipment and additional precautions to reduce the risk of a worker becoming a path for hazardous electrical energy.

The objective of this book is to acquaint the reader with explosive driven pulsed power devices, theory and applications. This includes those devices that convert the chemical energy stored in high explosives into electrical energy and that use shock waves generated by the explosives to release the energy stored in ferromagnetic or ferroelectric materials in the form of electrical energy. The reader might well ask why one should use explosive driven pulsed power for any application, since it is inherently single shot in nature.

Early in the morning on June 30, 1908, a giant airburst occurred over the basin of the Podkamennaya Tunguska River in Central Siberia, Russia, leveling trees over an area of 2,000 km2 (770 mi2) (Figure 1). Eyewitnesses described a ―fire ball, bright as the Sun‖ (Longo, 2007). The event produced seismic and pressure waves that were recorded all over the world and led to atmospheric phenomena (e.g. , bright nights, noctilucent clouds) observed over much of Eurasia.

A fully integrated and interconnected European Single Market covering telecoms, energy and transport is a prerequisite for competitiveness, jobs and growth. Achieving this requires affordable, accessible, efficient and secure network infrastructure. Accelerating the roll out of the digital economy will bring benefits across all sectors, through enhanced productivity, efficiency and innovation.

Sensors are still some time away from actual mass fabrication and use. Current smartsensor prototypes, such as the Berkeley Renee Mote, have a larger footprint and are generally restricted to the following sensor types: accelerometers, microphones, light, motion and magnetometers. We envision a design inclusive of these sensors types; however, our proposed application assumes a (not so) futuristic scenario that include sensors that test for nitrates (explosives), chemical toxins, biological toxins and radiation.

After two centuries of almost absolute belief in technical and economic progress, human society is in a period of reconsideration and elaboration of new strategies for the ongoing new century. Progress of our civilization with an explosive rise in world population has led to an enormously increased con- sumption of resources and to an equal threat to the environment. Coping with these problems requires all intellectual abilities of our society. In this endeav- or, biotechnology is considered to play a significant role.

Although the vast majority of earthquakes that occur in the world each year have natural causes, some of these earthquakes and a number of lesser magnitude seismic events are related to human activities and are called “induced seismic events” or “induced earthquakes.” Induced seismic activity has been documented since at least the 1920s and has been attributed to a range of human activities including the impoundment of large reservoirs behind dams, controlled explosions related to mining or construction, and underground nuclear tests.

About a year ago I was asked by a firm of insurance loss adjusters to investigate the possibility of reducing the anticipated overrun caused by an explosion at a power station. Based on previous experience of similar problems, I asked the contractors (a firm of international design and build constructors) to let me examine the critical path network which formed the basis of the computer-generated bar charts previously sent to the loss adjusters.

Recently, mobile communication services are penetrating into our society at an explosive growth rate. All of the current communication systems have adopted digital technology. Nowadays, the demand for various wideband services such as high-speed Internet access and video/high-quality image transmission, is increasing. The thirdgeneration mobile communication system has been, designed to support wideband services with the same quality as the fi xed networks.

Global change, including climate change, ecosystem shifts and biodiversity loss as a result of explosive human population growth and consumption, is emerging as one of the most important issues of our time (Vitousek, 1994). Climate change in particular appears to be altering the function, structure and stability of the Earth’s ecosystems (Lovelock, 2009). It has been marked by an 80% increase in atmospheric CO2 level and a 0.

The process of integrated circuits (IC) started its era of very-large-scale integration (VLSI) in 1970’s when thousands of transistors were integrated into a single chip. Since then, the transistors counts and clock frequencies of state-of-art chips have grown by orders of magnitude. Nowadays we are able to integrate more than a billion transistors into a single device. However, the term “VLSI” remains being commonly used, despite of some effort to coin a new term ultralarge- scale integration (ULSI) for finer distinctions many years ago.
