The identification and forecasting of cyber-attacks is crucial process. In this article, we describe a paradigm for
cyber security that makes use of data mining to forecast cyberattacks and identify appropriate countermeasures. The
framework's two primary elements are the surveillance and prevention of cyberattacks. The system constructs a predictive
model to forecast future cyberattacks after first extracting appropriate timing with cyberattacks from previous data that used
a decision tree based on the J48 algorithm. A variety of cyber-attacks, involving DDoS, port scans, and SQL Injection, are
described in the datasets. The suggested framework effectively recognizes cyberattacks and gives patterns associated with
them. The suggested predictive algorithm for identifying cyberattacks has a 99% average prediction performance. The
predictions model's test outcomes demonstrate how effective it is at spotting potential cyberattacks in the future. Moreover,
solutions like malware detection and monitoring were provided using data mining. Given the state of computer networks
today Users of computer networks ought to take security very seriously. In this article, implications of data mining for risk
evaluation and identification were highlighted, along with a unique method for quickly and accurately detecting malware.

An undamped (mechanical as well as electrical) oscillator subjected to a triangular pulse is generally analyzed via ordinary methods such as calculus. In this paper, an undamped (mechanical as well as electrical) oscillator subjected to a triangular pulse was analyzed to obtain its response via the Gupta integral transform (GT). It put forward a new technique for obtaining the response of an undamped oscillator subjected to a triangular pulse force and proves that the GT is an effective integral transform than calculus.

Scientists continue to improve the performance and efficiency of microstrip antenna designs as technology evolves, aiming to improve their adaptability to different environments and constraints. These antennas play an important role in modern communication technologies and in signal path systems demonstrate development, computer modeling and testing of microstrip line and coaxial cable with G-shaped slots in the strip. The antenna was designed and simulated using CST simulation software. Antenna performance was analyzed, considering several factors such as return loss, gain, directness, bandwidth, 3D radiation patterns and more. Simulated results showed that the proposed antennas exhibit a wide frequency range, with the microstrip line feed antenna and coaxial cable obtaining a value of 61% and 65%, respectively. These two antennas exhibited remarkable gain which are 7.784 dBm and 7.787 dBm, respectively. The microstrip line achieved a maximum feed efficiency of 93.12%, while the coaxial cable achieved a maximum feed efficiency of 97.65%. The findings suggest that providing the antenna with coaxial cable as opposed to fine tape line improves its performance. Antennas with coaxial cable have wider bandwidth, higher gain, and better efficiency compared to microstrip line antennas.

The problem of robotic control of an advanced missile requires designing control systems for remote-controlled missiles with sufficient abilities. These control systems need to handle navigation, guidance, propulsion, and potentially other tasks like target acquisition and avoidance of obstacles. The various aspects of missile dynamics are described by complex and non-linear differential equations. Due to this, it becomes difficult to obtain their analytical solutions. During system design and analysis, to solve these complex and non-linear differential equations, numerical techniques like Euler’s technique, the Runge-Kutta technique, or more advanced mathematical techniques are generally used. The advanced missile robotic control problem is one of the problems represented by second-order linear differential equations. In this paper, the integral Rohit transform (RT) has been applied to solve an advanced missile robotic control problem. This transformation has never been applied in working out the advanced missile robotic control problem. This paper applies a new technique for solving the second-order linear differential equation representing the advanced missile robotic control problem to obtain its required turn angle so that it will be able to catch and destroy the attacker. The necessary graphs are plotted to illustrate the numerical solution of the robotic control of an advanced missile. It reveals that the integral Rohit transform (RT) technique is an effective technique to solve the advanced missile robotic control problem.

The study demonstrated that noise changes the number of modes that can oscillate within the small cavity, and the spectral power is concentrated around the fundamental frequency. We also observed a reduction in the distortion that arises from the dispersive solitaire. This behaviour can be attributed to the magnitude of the pulse strength or the loss of its frequency due to the arbitrary interaction between the pulse train and the linear and nonlinear refractive index of the microcavity. The relationship between the dispersion and nonlinearity phenomena inside the microresonators is major in determining the inside field dynamics. The study showed that as the noise in microresonators cannot be cancelled, it is recommended to use a proper pulse width, intensity distribution, and power.

Next-generation optical fibers with diverse operating mechanisms, high functionality, and a porous structure that may be designed are known as photonic crystal fibers, or PCFs. In the meantime, two-dimensional graphene, possessing incredibly unique characteristics, is a perfect material for optoelectronic and optical uses. Recently, many studies have been published based on the integration of graphene with PCFs to create a new graphene PCF (Gr-PCF). There hybrid fibers show outstanding light-mater interaction over a broad spectrum range. This review starts with general introduction about photonic crystal fiber and analysis of optical properties. This is followed by a Plasmonic PCF then Graphene and physico-chemical properties of graphene nanomaterials. The review primarily covers the introduction of graphene and PCFs with many Applications including Optics Communications and different physical sensors.

In this paper, we introduced a class of analytic functions defined by (H–R) fractional derivative defined in the unit disk, we obtained coefficient bounded, so we obtained some theorems of this class. 2000Mathematics Subject classification: 30C45.

In this study, the first derivatives of this equation with respect to temperature (thermo-optic coefficients) and wavelength (spectral dispersion) were derived in the MATLAB software, and a special code was written to solve the equations and found for temperatures that range from 100 to 750 K and wavelength range from 1.2 to 14 µm. The computation results were compared with previously published data, and showed a good agreement. Once that was done, the values of phase velocity and group velocity that depend on refractive index and spectral dispersion in the medium were found. The phase velocity and group velocity were plotted in three dimensions to show the overall change over different values of wavelengths and temperature.
