Rovibrational Energies

A new accurate 6D PES is determined obtained from CCSD(T)-F12 calculations including two dissociation channels (HF + OH− and F− + H2O). A novel way is developed to use complex coordinates in variational nuclear motion computations. The rovibrational energies of F−(H2O) (the complete set up to 3700 cm−1) and F−(D2O) have been computed. The tunneling splittings describing the two complexes are obtained.

our aim is to develop a project that will benefit society. But nowadays it is employed to assist human in surveillance, rescue and recovery missions. This paper presents the prototype model of an UGV which is operated wirelessly through manual navigation commands based on the live video captured from the IP camera mounted on the board. The distance measurement is done by the Ultrasonic sensor from the obstacle and displayed in the LCD. The target tracking as well as attacking is done based on the obstacle and environment situation monitored in the live video.

Atomic Populations

We have theoretically studied the atomic populations, electromagnetically induced transparency (EIT), and dispersion in a three-level Λ-type system. The density matrix equations are set up with regard for the relaxation of populations of the ground states, and the optical Bloch equations are solved analytically in the weak probe field approximation. Decoherence effects in the ground and excited states on the EIT line shape and dispersive signals are studied, and it is found that the EIT line width increases and the peak height decreases, as the decoherence rates increase in the ground and excited states. On the other hand, we have observed that the dispersive signals are steeper and of high contrast for the lower decoherence rates in the ground and excited states. We have also analyzed the variations of atomic populations of the energy levels at the pump Rabi frequency, as well as the decoherence rate in the ground state.

Objective. To evaluate the ability of country ambulance services to provide first medical aid in trauma cases. Material and methods. A survey of chiefs of emergency medicine service was performed in October–November 2005, in which 34 of the 59 institutions (58%) were participating. The questionnaire presented questions concerning physical and human resources, performance values, and system configuration. The study has shown that emergency medicine service operates in radius of 23 km, each team providing service for about 40 000 inhabitants. Taking into consideration distance and average on-scene time values, emergency medicine service is capable to render the first medical aid within so-called “golden hour” in case the accident is reported immediately. The physical resources are not quite complete. Not all the cars are equipped with essential first aid measures. Among more rarely found resources are vacuum pumps, intubation sets, defibrillators, vacuum splints, back immobilization devices, and hammock immobilization devices. There are less mentioned resources than working teams and even more than two times less than emergency cars at all. Two-thirds of the operating emergency medicine services do not provide advanced life support procedures. The evaluation of theoretical/practical ability to provide some important medical procedures used in emergency medical care showed that medical staff quite often fails to perform defibrillation, intubation, and pleural cavity drainage. Conclusions. Country ambulance service network configuration according to area under service, number of people served, and response frequency comply with the requirement set. The ambulance vehicles lack complete set up as well as some important supplies. Only rarely the staff is skilled enough to perform such advanced life support procedures as intubation, defibrillation, and pleural drainage.

Accurate, experimental rotational–vibrational energy levels determined via the MARVEL algorithm and published recently for the 14NH3 molecule in J. Quant. Spectrosc. Radiat. Transfer, 2015, 116, 117–130 are analyzed to unravel the promoting and inhibiting effects of vibrations and rotations on the tunneling splittings of the corresponding symmetric (s) and antisymmetric (a) rovibrational energy level pairs.

Since its first appearance in April 2011, the term Industry 4.0 has become synonymous with the production of the future. Nearly all industrialized countries around the globe have set up research programs and industry support projects, and they encourage SMEs and government agencies to actively shape those developments and keep their industries competitive. Today, the Industry 4.0 has already arrived in factories, at least in the highly developed regions of the world. However, so far, most Industry 4.0 activities can be observed in the field of smart control systems. New technologies appear increasingly faster and find their application in production environments. TSN/SDN Ethernet will offer a complete compatible internet communication standard with real-time capabilities. Nevertheless, appropriate protocols for its application and interoperability are still a work in progress; they are called Asset Administration Shells and define a complete set of communication and service standards to easily connect any device from any supplier worldwide to a factory network. In conclusion, industrialized countries are not only suppliers of technologies to the rest of the world, they should also accept their responsibility to help less industrialized regions to find and implement their future business models in an interconnected world.

Orbital Angular Momentum Operator

A new kind of shift operators for infinite circular and spherical wells is identified. These shift operators depend on all spatial variables of quantum systems and connect some eigenstates of confined systems of different radiiRsharing energy levels with a common eigenvalue. In circular well, the momentum operatorsP±=Px±iPyplay the role of shift operators. ThePxandPyoperators, the third projection of the orbital angular momentum operatorLz, and the HamiltonianHform a complete set of commuting operators with the SO(2) symmetry. In spherical well, the shift operators establish a novel relation betweenψlm(r)andψ(l±1)(m±1)(r).

Previous calculations of the dependence on the strength of the external magnetic field H0 of the energy levels and the expected frequencies of nuclear spin resonance lines of Al27 nuclei in a single crystal of LiAl(SiO3)2 (spodumene) have been extended over a wide range of H0 to more general orientations of the crystal with respect to H0.In order to describe the variation with H0 of the relative signal strength of a nuclear spin resonance line in a crystal, as observed with a crossed-coil spectrometer, a system of modified Bloch equations has been set up which describe the behavior of the magnetization vector of a two-level system when transitions are induced by an oscillating magnetic field. Solutions of these equations are used to explain the difference in the dependence on H0 of signal strengths in crossed-coil and in single-coil spectrometers.

This paper proposes a complete set of Urban Parking Guidance and Information System, which includes Parking Subsystem and City Parking Subsystem. The system adopts wireless sense network based on ZigBee technology for the communication network. The parking information terminals that set up in the parking areas automatically identify the parking vehicles and upload the parking information. After processing the data, the Central Control Module would distribute the parking information by LCD screens for the drivers. In terms of parking supply and demand status, the system sends the separately parking information to the corresponding phone number. The system achieves barrier-free intelligent parking management by realizing functions such as three ways of releasing the information of parking lots, inquiry of parking location and convenient register operation.
