Complementary metal oxide semiconductor (CMOS) integrated circuits (ICs) have recently focused on smaller size, lower supply voltage, and power consumption, contributing to the development of power and noise efficient biomedical devices. Since the nature of the biomedical signal is analog, power efficient analog to digital converter (ADC) is needed to translate these signals from physical to digital domain for further processing. This conversion process requires a comparator circuit which becomes the core of energy efficient ADCs. However, the speed and power consumption represent challenges for such designs. This paper presents a CMOS high speed, and low power comparator design used for successive approximation registerSAR ADCs. The proposed design is simulated and analyzed using 65 nm CMOS process. Simulation results for the proposed comparator show that the circuit consumes 70 μ w at 5 GHz of sampling clock with 1V supply. The implications of these results and how critical can the circuit parameters limit the dynamic performance of the comparator circuit are discussed.

Isolated microgrids have become an important topic in research; they can provide energy to remote areas using the available local energy resources including the renewable ones. However, there are some technical problems that face their increasing use such as the frequency deviations specially if renewable sources are used in the microgrid. This work presents a control scheme to minimize the fluctuation in frequency of an isolated microgrid comprising Renewable Energy Sources (RES). The presence of the fluctuating RES in the microgrid leads to deviations in the frequency which in turn can affect stability not to mention performance. Decentralized Robust H infinity (H∞) loop shaping controllers are proposed to keep the deviation in frequency to a minimum in the presence of high levels of uncertainties and provide good disturbance rejection. Particle Swarm optimization is used for H∞ loop shaping controllers and the results are compared against those of PID controllers and shows the effectiveness of the proposed control in terms of robustness, stability and performance.

Studying of flying vehicle motion contains many stochastic criteria with which obligates the control system designer to take into consideration the most effective parameters in control system analysis. These criteria changes with the nature, shape and mission required from this flying vehicle. With the introduction of long slender bodies, the problem of structural flexibility became acute. This flexibility causes additional aerodynamic loads, which in turn cause additional flexure. In addition, coupling occurs between the elastic modes and the control system as the gyros and accelerometers sense the flexure and the rigid body motions. In this paper, we demonstrate a method for determining the natural frequencies and mode shapes of the body bending modes. The work resumes with the derivation of the uncoupled body bending equations in normalized coordinates and finally the transfer function for the flexible vehicle is derived and then the flexibility effect on the system responses is presented. This work is mainly contributed to clarify the amount of airframe flexibility effect on control system behavior and if there is need to compensate this effect.

Photonic network was used with fire control system by replacing the copper cables with polymer optical fibers in order to increase the transmission data rate and the bandwidth. In this paper, CYTOP was chosen to be used to transmit the different signals that are sent from several sensors to ballistic computer due to the superior performance among the other types of polymer fibers. The proposed special photonic networks were implemented for different multiplexing techniques using optisystem software. These techniques were Optical Time Division Multiplexing (OTDM), Optical Wavelength Division Multiplexing (OWDM), and Mode Division Multiplexing (MDM). Based on simulated Q factor, BER, and the eye diagram, OWDM showed the highest performance with increasing number of laser sources (8 laser sources). Hybrid OWDM-MDM network was proposed to minimize the number of laser sources (4 laser sources) while keeping high performance which makes it the most suitable choice for special platforms.

A new technique cancels the sidelobe effect, where a novel sidelobe cancellation filter (SCF) is developed and applied for compound-Barker in combination with linear frequency modulation (LFM) or polyphase waveform. The combination increase number of wave form can be generated and length of code that increase average power that increased signal to noise ratio after comparison. The reverse filter is used to apply a new SCF method. The SCF proposal is integrated into a matched filter (MF). The modified-MF (Mod-MF) can be applied to remove sidelobes for waveform generated from compound-Barker combined with LFM or polyphase. Mathematical derivation of the general, closed form of the SCF proposal. Furthermore, this formula depends on the Barker compound length, LFM parameters and polyphase phase. The filter proposed was generated without the need for adaptive strategies or iteration methods. The Mod-MF impacted preserves the mainline ’s impulse response width and peak values. For a small radar cross section (RCS) the proposed SCF can be detected, even though it is masked by a large RCS target lobe. Finally, the proposed SCF filter in experimental open area is tested for practical work.

According to Medical Statistics conducted in the USA, the number of patients who die every year from Medical errors are estimated to be around 200 to 400 thousand. The most common types of medical mistakes are (Billing errors, incorrect medication/incorrect dosage). Moving towards Electronic Health Records (EHR) instead of the paper-based system can prevent Medical errors. The (EHR) faces challenges regarding the issues of security and privacy. Utilizing blockchain can provide the proper solution to the above-stated challenges. This paper aims to introduce a new supervising strategy regarding accessing, sharing, and storing the (EHR). The proposed strategy enhances the security in a distributed network environment, through applying blockchain technology and hash table. Furthermore, it is applying a newly developed collision-resistant hash function in generating a unique ID for each patient in the EHR System. The Proposed scenario will improve the overall performance of the EHR system making it more efficient and reliable than the traditional system.

nowadays, solving the positioning problem of unmanned ground or aerial vehicle became more and more pivotal. Such vehicles use a navigation system based on the Global Positioning System (GPS) to solve this issue. However, this system could suffer from jamming and satellites visibility especially in harsh environments. Thus, it is necessary to design and implement an integrated system based on the integration between Inertial Navigation System (INS) and GPS to provide a promising solution to guarantee the availability of the positioning solution in these environments. In addition, INS/GPS integration system overcomes the problems faced by each system individually in short and long term accuracy. The purpose of this research is to design and implement an INS/GPS integrated system on an embedded system. It is carried out through two main steps; the first one is the design of an integration algorithm to fuse the INS and the GPS data together using Extended Kalman Filter (EKF). After this step, the second one is the implementation of this system on a Tiva C microcontroller. All the sensors used in hardware implementation are low cost sensor and available on-line as a commercial product. Then, the positioning problem of moving vehicles can be solved by using GPS/INS integration system based on low cost sensors.

Some DC converters are an important part of DC system because these are the main control in DC voltage regulator. The desired performance of this DC converter is following the reference voltage and having a fast response. This paper designs controller using the principle of feedback control to operate a buck converter. The using of a buck converter to control the system has the aim to set the DC bus voltage and then control DC motor speed. The dynamic model of the system is given in the form of a state space, this form is used for investigation of the system. In order to design controller, several system parameters are needed. Giving an observer is promised to reduce the number of sensors used on the system. In the simulation, the PID controller is used to compare with the proposed controller. The performance produced by the proposed controller have a simple design and good response. The performance of the controller is inspected in two terms, angular velocity and armature current. The output response is forced to reach the desired angular velocity value.
