The high data rates required for next generation applications necessitate the use of millimeter wave and terahertz bands where bandwidth is abundant.Due to high path loss in these bands, antenna arrays (AAs) are needed to focus the signal in highly directional beams in the desired directions.However, highly directional communication links in these
This paper is dedicated to the directions of development of rural areas, primarily agricultural areas of the Podlaskie voivodeship, which in light of current criteria has been qualified almost entirely as problem area (ONW).Results presented are culmination of research related to issues Guide Rail of problem areas primarily in the area of the Podla
While modern trends emphasise the need to educate and train the retarded child and adult, many aspects of mental retardation remain in the medical realm.There Small Animal is therefore much that can be done by the medical and paramedical worker to assist the retarded child and its family; not only from the point of view of health but even to achiev
Sensitivity kernels or partial derivatives of phase velocity (c) and group velocity (U) with respect to medium parameters are useful to interpret a given set of observed surface wave velocity data.In addition to phase velocities, group velocities are also being observed to find the radial anisotropy of the crust and mantle.However, sensitivities of
