A Review to do Fishermen Boat Automation with Artificial Intelligence for Sustainable Fishing Experience Ensuring Safety, Security, Navigation and Sharing Information for Omani Fishermen
Fishing wealth is one of the richest resources in the Sultanate of Oman. It is considered as one of the most important economic developments that nation depends on in a larger way. The Sultanate of Oman is characterized by the presence of a large fishing fleet as the number of fishing vessels and boats in it. Good research with the application of modern technology in fishermen boats is required to increase the quality of fishing by providing fishermen with a safe and secure fishing experience. Artificial intelligence (AI) in boat automation technology is new and it is a mandatory demand for Oman’s fisheries sector. At the time of fishing, there are a lot of problems fishermen face such as weather changes, border tracking, navigation, illegal fishing, pirate attack, oil spill, technical fault in boats, etc. Therefore, the application of AI and related techniques in boat automation, information sharing, and preparation of documentation resources is very important in this sector. The main requirement for a fisherman is a high-quality fishing boat with proper communication devices to provide all the required information to fishermen and the control room. In this paper, a review has been made on fishermen’s boats with artificial intelligence for a sustainable fishing experience ensuring safety, security, navigation, and sharing information for Omani fishermen.

Impacts of human-related practices on Ommatissus lybicus infestations of date palm in Oman
Date palm cultivation is economically important in the Sultanate of Oman, with significant financial investments coming from both the government and private individuals. However, a widespread Dubas bug (DB) (Ommatissus lybicus Bergevin) infestation has impacted regions including the Middle East, North Africa, Southeast Russia, and Spain, resulting in widespread damages to date palms. In this study, techniques in spatial statistics including ordinary least squares (OLS), geographically weighted regression (GRW), and exploratory regression (ER) were applied to (a) model the correlation between DB infestations and human-related practices that include irrigation methods, row spacing, palm tree density, and management of undercover and intercropped vegetation, and (b) predict the locations of future DB infestations in northern Oman. Firstly, we extracted row spacing and palm tree density information from remote sensed satellite images. Secondly, we collected data on irrigation practices and management by using a simple questionnaire, augmented with spatial data. Thirdly, we conducted our statistical analyses using all possible combinations of values over a given set of candidate variables using the chosen predictive modelling and regression techniques. Lastly, we identified the combination of human-related practices that are most conducive to the survival and spread of DB. Our results show that there was a strong correlation between DB infestations and several human-related practices parameters (R2 = 0.70). Variables including palm tree density, spacing between trees (less than 5 x 5 m), insecticide application, date palm and farm service (pruning, dethroning, remove weeds, and thinning), irrigation systems, offshoots removal, fertilisation and labour (non-educated) issues, were all found to significantly influence the degree of DB infestations. This study is expected to help reduce the extent and cost of aerial and ground sprayings, while facilitating the allocation of date palm plantations. An integrated pest management (IPM) system monitoring DB infestations, driven by GIS and remote sensed data collections and spatial statistical models, will allow for an effective DB management program in Oman. This will in turn ensure the competitiveness of Oman in the global date fruits market and help preserve national yields.

Analysis of the stress field and strain rate in Zagros-Makran transition zone
Transition boundary between Zagros continental collision and Makran oceanic-continental subduction can be specified by two wide limits: (a) Oman Line is the seismicity boundary with a sizeable reduction in seismicity rate from Zagros in the west to Makran in the east; and (b) the Zendan-Minab-Palami (ZMP) fault system is believed to be a prominent tectonic boundary. The purpose of this paper is to analyze the stress field in the Zagros-Makran transition zone by the iterative joint inversion method developed by Vavrycuk (Geophysical Journal International 199:69-77, 2014). The results suggest a rather uniform pattern of the stress field around these two boundaries. We compare the results with the strain rates obtained from the Global Positioning System (GPS) network stations. In most cases, the velocity vectors show a relatively good agreement with the stress field except for the Bandar Abbas (BABS) station which displays a relatively large deviation between the stress field and the strain vector. This deviation probably reflects a specific location of the BABS station being in the transition zone between Zagros continental collision and Makran subduction zones.

Solar Resource Mapping of AL Duqm Industrial Area
The Sultanate of Oman has one of the highest percentages of potential solar radiation in the world, which puts it in an outstanding position to horde electricity generation plants through photovoltaic solar systems. Oman consists of 11 governorates, and each governorate is divided into many Willyiah, which are made up of small villages. Willyiah of Al Duqm is located in Al Wusta Governorate (19°39'42\"N 57°42'17\"E) in central-eastern Oman. This paper proposes the use of a monthly average hourly diffuse illuminance from meteorological data and from a Geographic Information System (GIS) to identify the best plots suitable for installing photovoltaic solar farms in the Al Duqm Industrial Area. Solar data collected in this study shows that the highest average annual solar radiation data recorded is 5,764 Wh/m2 in the Al Duqm area. Solar radiation data from 2000 to 2012 has been collected for further analysis. The Annual Energy Production (AEP) simulated using ArcGIS ranges between 6,028 Wh/m2 and 3,668 Wh/m2. This shows a very close estimation between simulation results and the data collected from the meteorological department in Oman.

The effect of transnational threats on the security of Persian Gulf maritime petroleum transportation
Today’s interconnected economy is dependent on petroleum products as a principal component of the energy mix and a critical element in global infrastructures. With the escalating demand for oil and natural gas, the world relies heavily on maritime transportation to move 62 % of world trade on fixed routes. The Persian Gulf countries are crucial because about 88 % of oil exports pass through the Strait of Hormuz. The Strait is strategically located between Iran and Oman, where 20 million barrels of crude oil per day is carried by supertankers. These shipments account for 40 % of seaborne oil traded worldwide. According to the Energy Information Administration, due to increasing demand this region will require 2.5 times more tankers than are in existence today to meet demand by 2025. Nevertheless, the persistent, expanding, and increasingly sophisticated physical attacks against maritime transportation present an alarming pattern. The focus of this article is three fold. First, to explain major transnational threats within the context of piracy and terrorism. Second, to present the costs and the economic impacts of piracy and terrorism on international trade. Third, to point out the main contributing factors involved in the increase in the number of attacks on maritime petroleum transportation vessels. Given the strategic importance of the Persian Gulf countries, due to their petroleum contributions to the world, this paper focuses on the maritime flows of petroleum from this region through navigation courses to Asia, the United States, and Europe.

The Ibadhi Imamate of Muhammad bin 'Abdallah al-Khalili (1920-54): The Last Chapter of a Lost and Forgotten Legacy
Oman provided ideal conditions, both internally and externally, for the emergence of an Ibadhi Imamate, which was therefore a political legacy rooted in Omani existence for over 1,000 years, from the time that Oman accepted the yoke of Ibadhi Islam. There was also an essentially dissimilar political legacy which contributed to the development of Oman. It was that of the coastal state, the Muscat Sultanate, epitomized in the tales of Sinbad the Sailor and the navigation logs left by such famed mariners as Ahmad ibn Majid. This legacy identifies Oman as a maritime trading state whose merchants as early as the eighth century traveled from one end of the monsoon region to the other, from China to the shores of East Africa. Here, Rabi deals with the former legacy, that of the Imamate of Oman that came to an end in 1954 and was swept into the ashbin of history, and examines the historical, intellectual and social perspectives and the nature of the Ibadhi Imamate.
