Individual Veri ability in Electronic Voting
upcommons.upc.eduElectronic voting systems have been around for a long time. The rst optical scanners were rst used in 1962, and Direct Recording Electronic Voting Machines (DREs) were introduced in 1975. Complex, time-consuming and error-prone count-ing processes have been made faster, easier and more reliable with electronic mech-anisms.
Thermal properties of graphene: Fundamentals and …
poplab.stanford.eduT o understand the thermal properties of graphene, one must fi rst inspect the lattice vibrational modes (phonons) of the material. The graphene unit cell, marked by dashed lines in Figure 1a , contains N = 2 carbon atoms. This leads to the formation of three acoustic (A) and 3 N – 3 = 3 optical (O) phonon modes,

ocw.mit.eduproperties, including electronic, vibrational, rotational, and electron and nuclear spin states and energies. From this information, we can often deduce a great deal of additional insight, including: Molecular identities – what is the sample composed of? Molecular conformations, geometries, and sizes . Chemical equilibria
Properties of materials - ASM International
www.asminternational.orgOptical properties relate to a material’s response to elec tromagnetic radiation, primarily visible light. Light can be absorbed, transmitted, or reflected. Optical properties are important for all materials, not just transparent materials (think photoelectric effect). Transmissivity

ocw.mit.eduImpurities that have their electronic energy levels close to the valence band extract electrons from the valence band leaving behind holes and are called “acceptors”. These impurities contribute to hole conductivity in semiconductor and result in “p-doping”.
