This paper presents a step in microlevel photovoltaic (PV) summation technology for combining unsymmetrical PV modules with differences in specification and age, relocation on nonfertile land, or multilocation mounting by designing an add-on modular hardware interface to a multi-input single-output (MISO) dc bus, using an MISO controller employing a suitable maximum power point (MPP) tracker under partial shading/long distance/mismatching PV module conditions along with a sensorless PV vector control inverter (PV-VCI) driving a three-phase asynchronous squirrel cage induction motor dedicated to irrigation, with the facility of autoconfiguration/autotuning at the beginning. A PV source gets automatically added/removed in a ramp profile in proportion to the load in steps, thus keeping ON only when required, enabling high efficiency, minimum heating, and prolonged life as that of a PV module. The contribution includes a reduced PV energy cost per watt by 24.10%, improved return on investment by 27.48%, improved water discharge yield by 11.06%, and improved MPP tracker impact by 14.59% with 90.88% MISO system efficiency compared to a normal scheme.

The blooming development in hydroponics has demanded the need of a self-controlled automated hydroponics system. Presently there are not many tools available and the existing ones have significant shortcomings for using the real time information. In this paper, a method is proposed to effectively use the data in real time to influence the counteractive steps. The work aims to build a self-controlled automated system which will be in itself smart and intelligent by optimizing the use of present technology. The real time data will be imported from a low cost AVR microcontroller board and the NI LabVIEW to monitor and automate the process in real time and to send this data over the network for IoT applications. The control will be provided by the traditional PID controller tuning. The system has been rigorously tested which proves the validity of the work and is cost effectiveness in such a way that it can be successfully implemented worldwide and in the developing states of India.

The bidirectional impeller pump is a kind of double impeller pump driven by single motor, which can pump and drain water with a single pump. This design effectively overcomes the disadvantages of complicated pipeline arrangement and poor reliability caused by multi-pump operation. In this paper, a bidirectional impeller pump is designed, which can realize the two-way flow of fluid through a special flow channel topology, and the structure and electromagnetic design of the core drive component of the permanent magnet brushless DC motor are carried out. The magnetic field numerical model of the motor is established by Maxwell, and the distribution characteristics of the air gap magnetic field and electromagnetic output characteristics are simulated and analyzed. Taking the output power and efficiency as the optimization objectives, the motor parameters such as the number of turns and wire diameter are optimized. The prototype and the experimental platform for the output characteristics of the bidirectional pump are designed and processed. The simulation results and the rationality of the structure are verified through experiments.

Robotic grasping has been one of research hotspots in the field of robotic and automation due to its wide application requirements. To our best knowledge, current work on grasping mainly focused on graspable region selection for the object observed using a pre-determined end-effector. However, in many applications of either industrial robots or service robots, there are various kinds of objects, using one specified end-effector limits the robots' manipulation capability. In this paper, we propose a method of end-effector selection and robust graspable point selection for various objects. An end-effector selection dataset of 3D models from Dex-Net 2.0 is generated and a fully convolutional network is trained to select the most suitable end-effector as well as compute the class activation map. We propose the CAM-based grasp sampling approach to take the place of random sampling, which combines local features and global information. Experimental results of end effector selection task on our dataset suggest that the powerful localization ability of fully convolutional network harm little to the performance. Compared with random sampling approach in grasp planning problem, our method is faster and more reliable to produce robust grasps.

To achieve better performance with various load and system parameters in controlling a current-source rectifier (CSR) with less computing cost, a neural-network-based implementation of three-logic space-vector modulation (SVM) is proposed in this research, and the random weight change (RWC)algorithm is employed for on-line parameter tuning. The scheme has been simulated in SABER simulation software and the result is compared with the conventional SVM method. The advantage of the method is explicit with a better performance under a non-rated system load. © 2010 ieee.

Graphical User Interfaces (GUIs) are becoming increasingly common for application software in process control. By necessity, process control applications manage numerous complex constraints. Conventional Interfaces display the states of a system without conveying the constraints which drastically reduce the evolutions which must be considered. Our model resolves this difficulty by presenting system parameters in the context of ecological constraints mirroring those of the underlying process. A simulation of a simple steam plant with five different GUIs was used in this experiment. The displays were a conventional Dials display, a Mimic display, an Object display, a Seesaw analogue, and a Fluid-tank analogue. Poor over-all performance in maintaining specified values was found for the Seesaw and the Object displays. The Dials and the Mimic displays performed similarly with greater accuracy. The best control was observed in the experimental Fluid-Tanks display. These Findings are consistent with our hypotheses. For over-all failure detection there were few differences between the Dials, Object and Fluid-Tank. The Seesaw display led the way with false alarms and latency of detection. The Mimic display produced average latencies but with poorer accuracy.

In many of the iris biometric applications plays a major role in tracking the gaze, detecting fatigue, and predicting the age of a person, *** were built for human-computer interaction and security applications such as border control applications or criminal tracking applications. In this paper, we proposed a novel CNN U-Net based model to perform the accurate segmentation of pupil. We experimented on the CASIA database and generated an accuracy of 90% in segmentation. We considered various parameters such as Accuracy, Loss, and Mean Square Error (MSE) to predict the efficiency of the model. The proposed system performed the segmentation of pupil from 512\times 512 images with MSE of 1.24. © 2020 ieee.

As GPU applications expand, the reliability of GPU is drawing more attention since even reliability-demanding applications are executed on GPUs. Silent data corruption (SDC) is widely studied both in irradiation experiments and fault injection experiments. On the other hand, detectable uncorrected error (DUE) is not well studied. This work focuses on DUEs reported by the GPU driver and analyzes those observed in fault injection and neutron irradiation experiments, where faults are injected in the control flow to change the program counter value unexpectedly. The DUE errors of GPU engine exception, GPU memory page fault, and GPU processing stop are observed in both the experiments. On the other hand, the DUE error categorized as internal microcontroller halt by the GPU driver, which is not found in the fault injection experiment, is observed frequently, suggesting the necessity of investigating the failures originating from the faults in the components invisible to programmers.
