Many people would expect C to be of type matrix as well. Whether C is a matrix depends on the implementation of operator∗. In the case that the operator returns a matrix then C is a matrix. For the sake of performance, computationally expensive operators very often return an Expression Template and delay the evaluation to a later point in time when it can be performed more efficiently—because w...

To prevent sympathetic detonation in a high performance magazine, barriers between stacks of munitions absorb donor fragments. Acceptor munitions may still initiate on impact of barrier debris or on being thrown into the walls of the magazine itself. These shocks can be reduced to a safe level by increasing the barrier's mass which reduces its velocity and the imparted shock. In addition a poro...

The economic advantages of electronic data interchange (EDI) are widely recognized. Nevertheless, the number of organisations and companies employing EDI is relatively small compared to the total number of businesses worldwide. The huge difference is caused by the fact that current EDI standards include a lot of complexity and their integration into existing applications is too expensive. This ...

To construct a bridge as a crossing building on a very wide river it might not used one span only, therefor, in middle of the river it is needed pillar as support. The existing of the pillars will change velocity distribution, surface water and topography of sediment, especially when the pillar is located on the bend of the river where the very large hydraulic can be hepened. Therefore, this st...

Background Amputation is a surgical procedure for the removal of a limb which is indicated when limb recovery is impossible. There are different types of amputation, and their causes can vary from one area to the other. Therefor, the aim of this study is to find out the patterns and causes of amputations in patients presented to Ayder Referral Hospital, Mekelle, Ethiopia. Methods the record o...

An experimental allergic encephalomyelitis was induced by bovine myelin basic protein (MBP) and bovine galactocerebroside (GC) on male guinea pigs. Animals were divided into five experimental and one control groups. Among the five experimental groups, three were inoculated with 75 micrograms, 150 micrograms and 300 micrograms of MBP, respectively, to see the dose dependency of demyelination. Th...

Modern tracking technology for full body tracking, also referred to as motion capturing, can be used as an alternative or a complementary method to video recordings (see also Chapter 72.a on documenting with data gloves for a discussion). It offers a high precision of position and orientation information regarding specific points of reference, which can be chosen by the experimenter. Motion tra...

Low Power consumption has become growing larger for communication systems and battery operated devices. These are laptop computers, multimedia products, and cell phones. For this battery operated devices, the energy consumption is a critical issue for design since it affect the batteries life. Thereby, the reduction of the energy consumption is become one of the most growing topics in the elect...

Motivated by the possible existence of post-natal cortical plasticity, we analyze Miller’s (J. Neurosci. 14 (1994) 409–441) correlation-based plasticity dynamics using sinusoidal patterns of varying frequency and orientation. After demonstrating that this leads to the formation of a cluttered receptive "eld (RF), and analyzing the reasons therefor, we propose a Kohonen-type, response-dependent ...

The information and communication technology (ICT) we interact with in daily life is more and more distributed in the environment (the so called intelligent space). Most of these devices have increasing calculation capacity and therefore the potential to contribute to an overall distributed calculation power and therefor a processing intelligence. These so called intelligent nodes can for examp...
