The growing complexity of analog circuits poses challenging constraints on analog simulation tools. Simulation based optimization approaches have gained a lot of interest to cut down the analog circuit design time and complexity. One of these approaches is the Bayesian optimization (BO) approach, which represents the analog circuit as a black box function, and incorporates optimization goal and constraints aiming to reach the optimum design parameters with the least possible simulation iterations. In this paper, a BO approach for automated sizing of analog circuits is discussed. The proposed approach uses Gaussian Process (GP) as a surrogate model and utilizes SOBOL sampling. The proposed algorithm is validated on a two-stage op amp benchmark circuit and compared to the literature work.

The controlling in the neuron cell activity can achieve by a different external stimulus such as electric stimulation. The neuron cell excitation can define by forming depolarize and hyperpolarize cell membrane. In this paper, we represent the effectiveness of mathematical simulation for the polarization rate. The polarization rate relies on several factors related to the excitation signal duration and the intensity of the applied electric signal. The effectiveness study and analysis of these factors improve the definition of the polarization rate.

Circuit simulation is a crucial but time-consuming step. Dense circuits and sub-circuits are significantly more expensive to simulate than sparse ones. In this paper, a novel dense sub-circuit reduction system is introduced. The proposed methodology uses dense sub-graph mining techniques on top of the model order reduction techniques to reduce the dense sub-circuits in the designs. This paper focuses on comparing four different dense sub-graph mining algorithms in the context of circuit reduction. The conducted experiments showed that the greedy approximation algorithm for edge density maximization is the most suitable for our circuit reduction problem since it provides the best results in terms of scalability on large graphs as well as the density and the size of the detected dense sub-graphs.

Medium Access Control (MAC) protocols play an important role in underwater environment communication. There is a strong need to enhance the performance of MAC protocols in Underwater Sensor Networks (UWSNs) especially improving the adequacy of ALOHA Protocols. In this paper, a Slotted-Buffering-ALOHA protocol is proposed. This protocol is based on three components: buffering, slot time, and Carrier Sense (CS). The simulation results demonstrated a superior execution of this protocol in the throughput rate, the energy consumption, and the average delay in comparison with the three protocols: slotted ALOHA, Slotted-CS ALOHA, and ST-Slotted-CS-ALOHA protocols.

Stroke is the second leading cause of death and a major cause of disability worldwide. Surviving a stroke will likely result in impairments that will need special care, with only 10%of stroke patients making a full recovery. The taxing amount required to assist in recovery and the scarcity of physiotherapists makes it hard and very expensive for stroke patients to seek treatment. This has caused a shift towards robotizing the process and using rehabilitation robotics for therapy and diagnosis of stroke patients, despite the high cost. This paper demonstrates a cheap diagnosing technique that uses common tools and an open-source machine learning algorithm. By using the built-in inertial measurement unit of smartphones and open-source gradient boosting, it was possible to diagnose a patient’s score when performing 3 tasks of the Fugl-Meyer upper-extremity assessment. The accuracy of the model was evaluated using 5-fold cross-validation and yielded an accuracy of 95.56%.

prepaid energy meter has been perform in many regions. Actually, the flaw of the system is the controlling behavior of the customers. The meter must be recharged. That’s why a smart meter system has been created to obtain all electrical energy consumption in a small region. The area consists of individual units like the room in the hall, the apartment in the building, the structure on the street, etc. Power grids,communications and power system simulation are designed. Data is processed and power consumption profiles are created for units for different periods of time obtained from simulations taking into account the definitions of the electricity grid, as well as taking advantage of the use of IoT advantages in how to separate power remotely when a theft is detected in an area. By using MATLAB Simulink the information was obtained from a specific apartment inside the building to calculate the energy through which the messages are displayed on the LCD screen, this system sends SMS messages to the consumer via GSM and also sends them to the electricity company in an encrypted form using arduino micro-controller.

Recognizing the prosody or arud of modern Arabic poems in an automatic way is a big challenge. One of these challenges is the rare work in this field. We found very few publications on recognizing the classical poems arud, but, as far as we know we did not find any publication on applying machine learning techniques to recognize the arud for modern poems where there are no definite numbers of feet for each verse, no fixed rhyme, and meters are mixed. In this paper, we introduce a new system using Artificial intelligence called “IMAP” to identify and recognize the arud for modern Arabic poems. Tafhela (Foot) is a group of syllables that form a prosodic unit regardless of word boundaries. The accuracy of our proposed algorithm was 99%.

Visible light communication (VLC) is considered one of the newest wireless communication technologies that provides transmitted signals with high data rate. Orthogonal frequency division multiplexing (OFDM) is used extensively in VLC due to its ability to support high speed transmission and it gets ride of the inter-symbol interference [1]. OFDM enhancement with wavelet based on discrete wavelet transform (DWT) has achieved remarkable performance compared to OFDM due to interesting wavelet characteristics. OFDM suffers from the issue of peak to average power ratio (PAPR) which reduces the system efficiency especially in VLC system due to the nonlinearity of light emitting diode (LED) which distorts the signal. Wavelet proved an improvement in PAPR reduction of the radiated signal. In our study, an exponential companding PAPR reduction technique is applied on a wavelet-OFDM which satisfies better enhancement in PAPR reduction of the transmitted signal.
