The nuclear physics experiments at the Thomas Jefferson National Accelerator Facility often require longitudinally polarized electrons to be simultaneously delivered to three experimental halls. The degree of longitudinal polarization to each hall varies as function of the accelerator settings, making it challenging in certain situations to deliver a high degree of longitudinal polarization to ...

We describe a method for mapping the functional regions of the brain using a transcranial magnetic stimulation (TMS) device. This device, when placed on a subject's scalp, stimulates the underlying neurons by generating focused magnetic eld pulses. A brain mapping is then generated by measuring responses of di erent motor and sensory functions to this stimulation. The key process in generating ...

In recent years several classic halls for chamber music were renovated and a few halls of similar capacity were built in Russia. We have selected the most interesting ones and measured their acoustical parameters. Here we are presenting detailed descriptions of five halls in Moscow, Tula, Ufa and Penza in combination with the measurement data. Some of them have long reverberation time and their...

Goldin argues that the most significant change in labor markets over the past century was the increased participation of women in the labor market. Figure 1 summarizes historical trends in mens' and womens' labor force participation.

Functional quality of the student residence halls has a great deal of importance due to their collective nature and the fact that they are considered as housing units, identifying and defining the role of intermediary spaces on the spatial organization and and spatial consociation of student residence halls which is a compound system of masses and spatial borderlines can bring order to its syst...

Prefabricated aluminium halls are usually temporary structures with multiple uses. Their biggest advantage is low weight resulting in lower transport costs and allowing for quick assembly. Today, there a growing demand to become permanent structures, therefore, meeting the requirements of EN 199x norm series, it necessary optimize calculation aspect conventional structural systems reinforced bo...
