In radio-frequency receivers, variable-gain amplifiers (VGAs) are often used in order to compensate for the change of the signal level during the channel transmission and to relax the constraints on the succeeding analog-to-digital converter (ADC). In this paper, a novel VGA is introduced using a floating-gate MOS transistor (FGMOS). The voltage gain, the linearity, the valid region for proper operation, and the sensitivity are discussed and quantitative expressions are derived for them. The performance of this amplifier is verified by simulation adopting the 45 nm CMOS technology with Vdd = 1 V.

IoT (Internet of Things) is a system where objects are embedded with sensor technology to interact with each other over wireless communication medium to generate, exchange and transfer data without human interaction. It provides interaction between physical world and cyber world which is known as cyber physical systems. IoT can be implemented as smart cities, smart homes, traffic management systems etc. Research has proven that, any system with the characteristics of remote management, dynamic topology, resource constraints and wireless communication medium are always susceptible to security issues. This research aims to investigate and identify the specific types of IoT applications suitable for UAE, analyse the potential security threats associated them and their impacts on these applications. A thorough exploration and review of the available literature has been done to identify the IoT application systems and related cyber vulnerabilities.

During the analysis of circuits containing multi transistors, the researcher is faced with a tremendous problem. This is due to the fact the MOS/BJT transistor is a four/three-terminal device with a large number of specifying parameters. In order to simplify the analysis, the four/three-terminal complicated MOS/BJT transistor can be replaced by a two-terminal fictitious resistor with a proper resistance. In this paper, a procedure is described to find a formula for the equivalent resistance of the MOS or the BJT transistor, and thus simplifying the analysis of such circuits considerably. Also, the procedure is applied to circuits containing a single transistor and to circuits containing series and parallel connections of transistors in order to estimate the propagation delays. The derived formulas are verified by comparison with the simulation results adopting the 65 nm CMOS technology with a power-supply voltage of 1 V.

In this paper, we present a spectral parallelism electronic system that works as a data acquisition and image reconstruction system for magnetic resonance imaging (MRI). It uses a custom receiver chain and narrowband bandpass filters. The broadband magnetic resonance (MR) signal is spectrally separated into multiple narrowband channels. Then each channel signal is processed individually and the system recombines the frequency-limited narrowband signals from the separate channels to reconstruct images or signal profiles. The final image is reconstructed by recombining all the channels data via weighted addition, where the weights correspond to the frequency responses of each narrowband filter. Results were obtained using a clinical MRI system and the images acquired by the developed embedded system showed the feasibility of achieving images with signal-to-noise ratio comparable to those produced by the clinical system.

Breast cancer is one of the most widespread diseases among women in the UAE and worldwide. Correct and early diagnosis is an extremely important step in rehabilitation and treatment. However, it is not an easy one due to several uncertainties in detection using mammograms. Machine Learning (ML) techniques can be used to develop tools for physicians that can be used as an effective mechanism for early detection and diagnosis of breast cancer which will greatly enhance the survival rate of patients. This paper compares three of the most popular ML techniques commonly used for breast cancer detection and diagnosis, namely Support Vector Machine (SVM), Random Forest (RF) and Bayesian Networks (BN). The Wisconsin original breast cancer data set was used as a training set to evaluate and compare the performance of the three ML classifiers in terms of key parameters such as accuracy, recall, precision and area of ROC. The results obtained in this paper provide an overview of the state of art ML techniques for breast cancer detection.

Renewable Energy sources are increasing their share in Distribution Generation System (DGS). The diversified sources of power generation can cause many Power Quality (PQ) problems. The need to monitor these changes is becoming paramount. The different level of voltage levels is also becoming a major area of interest. As the photovoltaic (PV) system consists of many parts they produce PQ disturbances coming from many sources. The power inverters and converters can inject harmonics into the system and grid. These disturbances have to be monitored so electrical equipment could be designed to improve the Power Quality (PQ) at the grid, and at the consumer level. The paper presents the results of monitoring of PQ disturbances at the consumer level that uses a hybrid power source (PV module) and utility power grid.

The Substrate Integrated Waveguides (SIWs), compared to the non-planar rectangular waveguides are flexible, compact, robust, easily manufactured and suitable for planar integration. SWI supports transmission of electromagnetic waves; they are also candidate in designing high speed circuits, antennas and couplers. In this paper, we propose a wire-loaded substrate integrated waveguide (SIW) structure that supports the energy-tunneling phenomenon. As anticipated, the proposed model supports energy tunneling depending upon the wire length. The resulting transmission response is, therefore, highly frequency selective. Hence, such configurations can be employed to design highly sensitive dielectric sensors and high frequency filters.

In this paper, we are targeting Altera Cyclone IV FPGA family to design an efficient GCD (Greatest Common Divisor) coprocessor based on Euclid's method with variable datapath sizes. The design was synthesized using seven chip technologies in terms of maximum frequency and critical path delay of the coprocessor. As a result, the comparison between different FPGA devices shows that Xilinx devices XC7VH290T-2-HCG1155 as well as XC7K70T-2-FBG676 recorded the best values of maximum frequencies of243.934 MHz down to 39.94 MHz for 32 bit and 1024 bit datapaths, respectively. Finally, the comparison with previous designs illustrates that the proposed coprocessor design has a throughput efficiency of even two times faster than other designs. Hence, the proposed work will help the FPGA system designers to better utilize the hardware performance for many applications such as cryptosystems design.

In this paper, we present the simulated design of a dual-polarized H-shaped aperture-coupled microstrip antenna for ultra-wideband radio frequency identification (UWB-RFID) applications. The antenna has a compact design (30 × 30 × 6.9 mm3) with a hybrid structure. The feed portion is on a Ferro A6M low-temperature co-fired ceramic (LTCC) substrate, while the square patches are deposited onto Rogers RT-5880 substrate layers. The antenna is designed to operate in the frequency range of 6–8 GHz. The proposed antenna achieves a dual-polarized broadside radiation pattern having a high gain of 7.71 dB. It also achieves a fractional bandwidth of 28.5% and a port isolation of more than −25 dB at the center frequency of 7 GHz.

With the increased volume of patent databases during the past years, it becomes necessary for companies to correctly classify and identify innovative patents in a timely manner though the use of automation. Although many patent classification methods have been proposed, the accuracy remains the most challenging factor for the success of a classification model. This paper presents an empirical study for automatic patent classification systems through the application of a three-phase model. Patent query, text processing, and the classification phases are applied, and a document frequency matrix and boosted tree (BT) classifier are used to classify patents into two classes. Model validation, accuracy and performance are calculated to determine the effectiveness of the proposed model.
