This research paper seeks to study the status of tourism promotion in Jordan, in particular via the Internet, with a future plan to develop this type of promotion based on the needs of the country .The aim of this research paper is to draw conclusions that help to know and understand this type of tourism promotion, And to know how to develop it in Hashemite Kingdom of Jordan to disseminate the maximum information about the Kingdom. This research paper is designed to determine the conditions of websites used in tourism promotion of Jordan, to find out the obstacles that face this type of promotion via websites, and the factors that affect its development .The findings and recommendations implied by this research paper will be presented to decision-makers in Jordan tourism sector to be taken into account.The research paper adopted carefully a survey form which is designed to collect data and information. It is used to know the trends and opinions of the research paper sample. The results showed that the tourism promotion through the Internet helps to increase competition in the prices of tourism, while the website design helps to spread information about the tourism offers. Both sexes consider that the website design as a means helps to ensure the information veracity of tourism offers.The research paper recommended to continue development of the role of tourism promotion through the Internet in spreading information about the tourism offers, so as to achieve the greatest possible benefits.

The main findings of the study is that there is no waste of time in travel and tourism companies in Jordan due to organizational and informational aspect, with the exception of certain matters such as conflict of business goals, there isn't coordination between departments of the company, and there isn't renewed and up-to-date information for decision-maker when taking any decision. The study also found that they don't manage time of choke points efficiently, and they're quick to respond to customer orders, except that it does not provide new tourism products to customers in a rapid and up-to-date wayMost importantly, the study recommended tourism and travel companies in Jordan to work to eliminate or decrease conflict in work objectives, guide the company's departments towards coordination among them, provide up-to-date and renewed information continuously for decision maker, and manage choke points time more efficiently, as well as to provide new tourist products for customers in a rapid and up-to-date way.<br /></span></p><span style="font-family: Times New Roman; font-size: small;"> </span>

Accurate simulations of gas turbines’ dynamic performance are essential for improvements in their practical performance and advancements in sustainable energy production. This paper presents models with extremely accurate simulations for a real dual-fuel gas turbine using two state-of-the-art techniques of neural networks: the dynamic neural network and deep neural network. The dynamic neural network has been realized via a nonlinear autoregressive network with exogenous inputs (NARX) artificial neural network (ANN), and the deep neural network has been based on a convolutional neural network (CNN). The outputs selected for simulations are: the output power, the exhausted temperature and the turbine speed or system frequency, whereas the inputs are the natural gas (NG) control valve, the pilot gas control valve and the compressor variables. The data-sets have been prepared in three essential formats for the training and validation of the networks: normalized data, standardized data and SI units’ data. Rigorous effort has been carried out for wide-range trials regarding tweaking the network structures and hyper-parameters, which leads to highly satisfactory results for both models (overall, the minimum recorded MSE in the training of the MISO NARX was 6.2626 × 10−9 and the maximum MSE that was recorded for the MISO CNN was 2.9210 × 10−4, for more than 15 h of GT operation). The results have shown a comparable satisfactory performance for both dynamic NARX ANN and the CNN with a slight superiority of NARX. It can be newly argued that the dynamic ANN is better than the deep learning ANN for the time-based performance simulation of gas turbines (GTs).

This study aims at pointing out and explaining the major factors that can help in implementing environmental accounting in the hotels of Aqaba Special Economic Zone, the study population is going to be the classified and rated hotels of the Aqaba Special Economic Zone Authority, which is 33 hotels in total. This study will basically focus on two tools for gathering the data and information required for achieving the objectives of the study, the financial reports published by the investment department of Aqaba and the questionnaire. The study shows that the hotels in Aqaba Special Economic Zone Authority face difficulties and obstacles in the implementation of environmental accounting because of factors related to legislation, level of awareness about environmental accounting, factors related to the hotels and the qualification of human resource.
