Liquid level control is one of the emerging control problems getting the interest of technical experts in the area of control. This paper is based on a fuzzy logic control strategy to maintain and stabilize the liquid level in a tank system that deals with pumping of liquid in tanks as well as regulating liquid level and pushing off the liquid into another tank. Fuzzy controller attains optimum performance by eliminating perturbation in steady state and vanishing the overshoot as compared to proportional, integral, and derivative (PID) controller. The proposed fuzzy logic controller shows minimal steady error as compared to PID controller. The defuzzification of the proposed scheme is based on the centroid method to obtain optimum results. The settling time is nearly 50 second while using fuzzy logic control as compared to 80 seconds in PID ...

Beam–column connections are the most critical components of reinforced concrete (RC) structures. ... more Beam–column connections are the most critical components of reinforced concrete (RC) structures. They serve as a load transfer path and take a significant portion of the overall shear. Joints in RC structures constructed with no seismic provisions have an insufficient capacity and ductility under lateral loading and can cause the progressive failure of the entire structure. The joint may fail in the shear prior to the connecting beam and column elements. Therefore, several modeling techniques have been devised in the past to capture the non-linear response of such joints. Modeling techniques used to capture the non-linear response of reinforced-concrete-beam–column joints range from simplified lumped plasticity models to detailed fiber-based finite element (FE) models. The macro-modeling technique for joint modeling is highly efficient in terms of the computational effort, analysis time, and computer memory requirements, and is one of the most widely used modeling techniques. The no...

However, researchers and science educators in remote areas can often find it difficult to access the latest genetic technologies, probably due to its high costs and lack of suitable infrastructure. Recent technological innovations are resulting in portable, low-cost instruments that enable next-generation sequencing in remote environments, offering new opportunities to generate a more widespread network of trained geneticists [2]. We need to formalize educational efforts to teach students and young researchers with hands-on training to excel in molecular and bioinformatics knowledge. Here, we report our experience of using the MinION pocket size sequencer in a graduate course. The graduate course had some theoretical lectures that explained t...

Infectious diseases are considered the main cause of deaths among the top ten worldwide, as per the World Health Organization (WHO). Therefore, tracking and estimating the evolution of these diseases are important to make intervention strategies. We study a real case in which some uncertain variables such as model disturbances, uncertain input and output measurement noise are not exactly available but belong to an interval. Moreover, the uncertain transmission bound rate from the susceptible towards the exposed stage is not available for measurement. We designed an interval estimator using an observability matrix that generates a tight interval vector for the actual states of the SEIR model in a guaranteed way without computing the observer gain. As the developed ...

Despite of the benefits gained from GSD, the developer organizations still face a lot of difficulties in integrating the software components, developed by various GSD teams, into a final product. In our previous study we identified a list of nine critical success factors (CSFs) in the software integration process for GSD vendors, using systematic literature review (SLR) method. In order to validate findings of the SLR, we conducted an empirical study using a questionnaire survey in GSD industry. The findings of our industrial survey are mostly coherent with the SLR findings. However, there is a difference in ranks of the various CSFs across the two data sets (SLR and Industrial Survey).

The analysis proves the location dependent based characteristics of in vivo channel. The results clearly show the highly multipath scenario. It can also be observed that the multipath effect of the channel is much higher in the denser areas, i.e. an antenna placed within the intestine area or inside the stomach. Results prove that in vivo channel is different from a conventional communication channel and therefore extensive studies need to be done to understand the channel.

It is shown that the location dependent characteristics are not only dependent on the in-vivo devices placed inside the human body but also the position of ex-vivo devices can impact the channel. Results are calculated using the mathematical model and curve fitting technique by calculation of the Root Mean Square Error (RMSE). The statistics of error prediction among the measured data and the proposed model is RMSE = 14.46 for the right lateral and RMSE = 11.63 for the left lateral respectively. These results will help system designer in accurate link budget calculation for designing enhance implantable devices.

It enables floor-cleaning robots to identify and avoid hard-to-clean debris, specifically large liquid spillage debris. This paper proposes a debris-detection and classification scheme for an autonomous floor-cleaning robot using a deep Convolutional Neural Network (CNN) and Support Vector Machine (SVM) cascaded technique. The SSD (Single-Shot MultiBox Detector) MobileNet CNN architecture is used for classifying the solid and liquid spill debris on the floor through the captured image. Then, the SVM model is employed for binary classification of liquid spillage regions based on size, which helps floor-cleaning devices to identify the larger liquid spillage debris regions, considered as hard-to-clean debris in this work. The experimental results prove that the proposed technique can efficiently detect and classify the debris on the floor and achieves 95.5% percent classification accurac...

By conducting simulations using a bandwidth (BW) of 50 MHz, we observed that the in vivo radio channel is affected by small-scale fading. This fading results in inter-symbol interference (ISI) affecting upcoming symbol transmission, causing delayed versions of the symbols to arrive at the receiver side and causes increase in BER. A 29 taps channel was observed from the experimentally measured data using a human cadaver and BER was calculated for the measured in vivo channel response along with the ideal additive white Gaussian noise (AWGN) and Rayleigh channel models. Linear and nonlinear adaptive equalizers i.e., decision feedback equalizer (DFE) and least mean square (LMS) were used to improve the BER performance of the in vivo radio channel. It is noticed that both the equalizers improve the BER, but DFE has better BER compared to LMS and shows a 2 dB and 4 dB performance gain of DFE over the LMS at Eb/No = 12 dB and at Eb/No = 14 dB, respectively. The current findings will help guide future researchers and designers in enhancing systems performance of an ultra-wideband in vivo wireless systems.
