In the present work, the exact diagonalization method had been implemented to calculate the ground state energy of shallow donor impurity located at finite distance along the growth axis in GaAs/AlGaAs heterostructure in the presence of a magnetic field taken to be along z direction. The impurity binding energy of the ground state had been calculated as a function of confining frequency and mag...

Wireless sensor networks (WSNs) are widely applied to many applications. Reducing energy consumption plays an important role in WSN. The concept of clustering is one of the popular energy-efficient protocols and it is applied to SEP, DEEC and SGCH technologies. Since the communication energy consumption depends on the communication distance, the communication distance and the residual energy of...

Introduction: The use of electrons in the electron therapy to destroy tumoral tissue is dedicated significant contribution of different methods of radiation therapy. Scattered radiation due to exited electrons of the applicator affect the dose out of the field in the patient's normal tissue. The aim of this study is to determine the peripheral dose outside the applicator in the...

State = R≥0 ×R≥0 For an abstract state (d, a), we call dist(d, a) = d+ a the energy-adjusted distance. The computational state comprises: • A simple distance d ∈ R≥0 to the base station, like the simple distance of an abstract state. • An energy level e ∈ Energy. • An energy-faithful adjustment f ∈ R≥0 capturing energy deficiencies along the route to the base station. • A table nt containing en...

for the urban transportation because of their sustainability, High torque, low volume, zero emission and energy saving. Electric scooter can go certain limit of distance based on the battery capacity it consists. This paper presents the model construction of an energy regenerative electric scooter via MATLAB/SIMULINK so that one can evaluate the performance of the energy recycling technique for...

introduction: this study aimed to assess the scanning electron microscope (sem) analysis of tooth surface irradiated by erbium:yttrium–aluminum–garnet (er:yag) laser with various parameters. methods: number of 25 extracted human third molars free of caries were used in this study. the teeth were put into 5 groups for laser irradiation as follows: group 1 (power: 0.5 w, energy: 50 mj); group 2 (...

We provide a unifying framework linking two classes of statistics used in two-sample and independence testing: on the one hand, the energy distances and distance covariances from the statistics literature; on the other, Maximum Mean Discrepancies (MMD), i.e., distances between embeddings of distributions to reproducing kernel Hilbert spaces (RKHS), as established in machine learning. In the cas...
