Internet of Things (IoT) am.ng of all the technology revolutions has been considered the next evolution of the internet. IoT has becom. a far m.re popular area in the com.uting world. IoT com.ined a huge num.er of things (devices) that can be connected through the internet. The purpose: this paper aim. to explore the concept of the Internet of Things (IoT) generally and outline the m.in definitions of IoT. The paper also aim. to exam.ne and discuss the obstacles and potential benefits of IoT in Saudi universities. m.thodology: the researchers reviewed the previous literature and focused on several databases to use the recent studies and research related to the IoT. Then, the researchers also used quantitative m.thodology to exam.ne the factors affecting the obstacles and potential benefits of IoT. The data were collected by using a questionnaire distributed online am.ng academ.c staff and a total of 150 participants com.leted the survey. Finding: the result of this study reveals there are twelve factors that affect the potential benefits of using IoT such as reducing hum.n errors, increasing business incom. and worker’s productivity. It also shows the eighteen factors which affect obstacles the IoT use, for exam.le sensors’ cost, data privacy, and data security. These factors have the m.st influence on using IoT in Saudi universities.

This study aim. to provide electricity to a rem.te village in the Union of Com.ros that has been affected by energy problem. for over 40 years. The study uses a 50 kW diesel generator, a 10 kW wind turbine, 1500 kW photovoltaic solar panels, a converter, and storage batteries as the proposed sources. The m.in objective of this study is to conduct a detailed analysis and optim.zation of a hybrid diesel and renewable energy system.to m.et the electricity dem.nd of a rem.te area village of 800 to 1500 inhabitants located in the north of Ngazidja Island in Com.ros. The study uses the Hybrid Optim.zation m.del for Electric Renewable (HOm.R) Pro to conduct sim.lations and optim.ze the analysis using m.teorological data from.Com.ros. The results show that hybrid com.ination is m.re profitable in term. of m.rgin on econom.c cost with a less expensive investm.nt. With a diesel cost of $1/L, an average wind speed of 5.09 m.s and a solar irradiation value of 6.14 kWh/m.sup>2/day, the system.works well with a proportion of renewable energy production of 99.44% with an em.ssion quantity of 1311.407 kg/year. 99.2% of the production com.s from.renewable sources with an estim.ted energy surplus of 2,125,344 kWh/year with the cost of electricity (COE) estim.ted at $0.18/kWh, presenting a cost-effective alternative com.ared to current m.rket rates. These results present better optim.zation of the used hybrid energy system. satisfying energy dem.nd and reducing the environm.ntal im.act.

It is very im.ortant for organizations to develop a com.etitive advantage for long-term.survival in the m.rket. For this purpose, the m.in objective of the study was to assess the role of data m.ning and em.loyee training & Developm.nt to gain a com.etitive advantage. m.reover, the m.diating role of personnel role and knowledge m.nagem.nt is also assessed in the present study. The data in the present study were collected from.the em.loyees of Sm.s in KSA using convenient sam.ling. The response rate of the study was 58.36%. For the analysis of the collected data, the study used PLS 3.2.9. The findings of the study reveal that data m.ning and training and developm.nt plays an im.ortant role for organizations to gain a com.etitive advantage through Knowledge m.nagem.nt and personnel role. The findings of the study fill the gap of lim.ted studies conducted regarding Sm.s of KSA to gain a com.etitive advantage. The findings of the study are helpful for the policym.kers of Sm.s around the globe.
