This study aims to investigate the academic leaders’ perceptions towards the degree of availability of the dimensions of organizational immunity systems at the University of Tabuk, as well as to reveal the statistically significant differences between the average responses of the study sample members about the degree of availability of these dimensions at their university due to the variables of (gender, leadership position, and college specialization). To achieve the objectives of the study, a descriptive survey method was used. The study population consisted of (200) male and female leaders who were academic leaders at the University of Tabuk. A questionnaire was used as a tool for collecting data, which its validity and reliability were confirmed through the internal consistency coefficient by Cronbach's alpha. The revealed that the degree of availability of the dimensions of organizational immunity systems at the University of Tabuk in the Kingdom of Saudi Arabia, in general, was a medium level of availability with a mean of (2.97). The axis: "Natural Organizational immunity" came in the first order with a mean of (3.02) and a medium level of availability followed by the axis: Acquired Organizational immunity in the second-order with an average of (2.88), and a medium level of availability.
The results revealed also that there were statistically significant differences attributed to the variable of (gender) between the average responses of the study sample about the degree of availability of the dimensions of the Organizational immune systems in general (the tool as a whole), and in the axis of natural organizational immunity as a whole and its dimensions (information, stimuli). There were statistically significant differences in the dimension of organizational memory from the axis of acquired organizational immunity in favor of females, there were no other significant differences discovered.
The results also revealed that there were statistically significant differences attributed to the variable of (leadership position) in the two dimensions (organizational structure, decision-making rights) of the axis of natural organizational immunity, and in my dimensions (organizational memory, and benchmarking) of the axis of acquired organizational immunity, while there were no other significant differences discovered.
The study suggested a set of important recommendations that support the University of Tabuk in strengthening its organizational immunity by applying all necessary measures and procedures to confront various future Organizational challenges.

In this work, the performance of the receiver in a quantum cryptography system based on BB84 protocol is scaled by calculating the Quantum Bit Error Rate (QBER) of the receiver. To apply this performance test, an optical setup was arranged and a circuit was designed and implemented to calculate the QBER. This electronic circuit is used to calculate the number of counts per second generated by the avalanche photodiodes set in the receiver. The calculated counts per second are used to calculate the QBER for the receiver that gives an indication for the performance of the receiver. Minimum QBER, 6%, was obtained with avalanche photodiode excess voltage equals to 2V and laser diode power of 3.16 nW at avalanche photodiode temperature of -10

Smart cities have recently undergone a fundamental evolution that has greatly increased their potentials. In reality, recent advances in the Internet of Things (IoT) have created new opportunities by solving a number of critical issues that are allowing innovations for smart cities as well as the creation and computerization of cutting-edge services and applications for the many city partners. In order to further the development of smart cities toward compelling sharing and connection, this study will explore the information innovation in smart cities in light of the Internet of Things (IoT) and cloud computing (CC). IoT data is first collected in the context of smart cities. The data that is gathered is uniform. The Internet of Things,
