Transmission technology

The study advocates for the seamless integration of BIM, creating digital modeling that encompasses various input data, from geometry to costs. This integrated approach enhances real-time collaboration, mitigates errors during design, and streamlines construction processes by aiding scheduling, resource allocation, and progress monitoring.

The management of dairy farming has been historically based on experience and the skills the farm operator has in planning and decisions made. In cases where the farm has large herds, a farming system must be in place, thereby bring an evolution in dairy management, which is datadriven. Precision technologies can bring about increased efficiency and decision making in dairy management. Total farmers that have already adopted the technology is still relatively low, although data shows a growth in the adoption rate.

In this work, nanoscale bimetallic PtNi, PtCo, PtCu catalysts on carbon Vulcan XC72R as supports were synthesized by reduction method under ultrasonic irradiation. The morphology, structure and specific area of synthesized materials were characterized by X-Ray diffraction (XRD), transmission electron microscopy (TEM). The catalytic activity for oxygen reduction reaction (ORR) of PtM/C was investigated by CV and linear sweep voltammetry (LSV) under simulated fuel cell working conditions.

Currently, WiFi, 3G/4G mobile communications are very popular and available in almost every place. Many Internet of Things (IoT) applications based on WiFi and 3G/4G technology modules have been developed and applied directly to social life. However, for applications with WiFi also take some limitations such as short distance transmission and large power consumption.

The adsorption of uranium (VI) by calcium alginate beads was examined by batch experiments. The effects of environmental conditions on U (VI) adsorption were studied, including contact time, pH, initial concentration of U (VI), and temperature. The alginate beads were characterized by using scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. Fourier transform infrared spectra indicated that hydroxyl and alkoxy groups are present at the surface of the beads.

In the Pt/
-Al2O3 catalysts, the distribution of uniform, small particle-size Pt metal on the carrier with high surface area of metal will result in high catalytic activities and will economize noble metals. The distribution of metal depends on the technology of preparation and postpreparation. The influences of the impregnating, drying, calcining and reducing on the distribution of metal have been studied using by physic methods, scan electronic microscope (SEM), transmission electronic microscope (TEM), and the hydrogen distribution has been measured by the method of hydrogen absorption.

Carrier Sense Multiple Access (CSMA) is a probabilisticMedia Access Control (MAC) protocol in which a node verifies the absence of other traffic before transmitting on a shared transmission medium CAN uses a nondestructive bitwise arbitration, which means that messages remain intact after arbitration is completed even if collisions are detected. All the arbitration takes place without corruption or delay of the message that wins the arbitration.

ANALOGUE AND DIGITAL NETWORKS Digital technology in the telephone network is nothing new. Take all the relays in older exchanges as an example. Relays are either "off" or "on", and there is no state in between these. Suitable combinations of relays could build up and "remember" numbers - perhaps a far-fetched example, but in was digital, so it will serve!...

In this paper, we are dealing with a L-band power combiner method using the Wilkinson bridge. This is a modern power combination technique in the microwave technology. The design and simulink of the basic power moduls and Wilkinson bridge were performed using the ADS soflware. We have researched, designed and fabricated the power combination from the basic 200W moduls. The experimental results showed that power combination method using the Wilkinson bridge may be applicable in the L-band transmission....
