Whole-Genome Identification and Comparative Expression Analysis of Anthocyanin Biosynthetic Genes in Brassica napus

Anthocyanins contribute to most colors of plants and play protective roles in response to abiotic stresses. Brassica napus is widely cultivated worldwide as both an oilseed and a vegetable. However, only several high anthocyanin-containing cultivars have been reported, and the mechanisms of anthocyanin accumulation have not been well-elucidated in B. napus. Here, the phenotype, comparative whole-genome identification, and gene expression analysis were performed to investigate the dynamic change of the anthocyanin content and the gene expression patterns of anthocyanin biosynthetic genes (ABGs) in B. napus. A total of 152 ABGs were identified in the B. napus reference genome. To screen out the critical genes involved in anthocyanin biosynthesis and accumulation, the RNA-seq of young leaves of two B. napus lines with purple leaves (PL) or green leaves (GL), and their F1 progeny at 41, 91, and 101 days were performed to identify the differentially expressed genes. The comparative expression analysis of these ABGs indicated that the upregulation of TT8 together with its target genes (such as DFR, ANS, UFGT, and TT19) might promote the anthocyanin accumulation in PL at the early developmental stage (41–91 days). While the downregulation of those ABGs and anthocyanin degradation at the late developmental stage (91–101 days) might result in the decrease in anthocyanin accumulation. Our results would enhance the understanding of the regulatory network of anthocyanin dynamic accumulation in B. napus.
Moisture availability and crop production.

ABSTRACT THE level of crop production de- pends upon many factors. One of the important influences is the degree of moisture adequacy or deficit. The effects of timing of water deficits during various stages of growth are briefly described. Providing deficits are not during critical periods, there is a surprising degree of uniformity of response to moisture adequacy as measured by the degree to which evapotranspirative demand, ET, is met. Methods for estimating ET and the dependability of rainfall are given. A tentative classification of climate for agricultural production is presented.
Bridging the gap between design and simulation of low voltage CMOS circuits

This work proposes a simplified MOSFET model based on the Advanced Compact MOSFET (ACM) model, which contains only four parameters to assist the designer in understanding how the main MOSFET parameters affect the design. The 4-parameter model was implemented in Verilog-A to simulate different circuits designed with the ACM model. A CMOS inverter and a ring oscillator were designed and simulated, either using the 4-parameter ACM model or the BSIM model. The simulation results demonstrate that the 4-parameter model is very suitable for ultra-low-voltage (ULV) modeling. In the ultra-low-voltage domain, some of the secondary effects of the MOSFET are not relevant and thus not included in the 4-parameter model. A simplified MOSFET model for the ULV domain is of great importance to applications such as energy harvesting, sensor nodes for the Internet of Things, and always-on circuits.
Relationship between settling time and pole–zero placements for three-stage CMOS opamp

In this article, the effect of pole–zero placements on settling time has been analysed for a three-stage CMOS operational amplifier (opamp) with nested Miller compensation (NMC) and reversed nested Miller compensation (RNMC) schemes. In this study, optimised balancing of speed and power is done for a three-stage CMOS opamp for a given load condition (on-chip opamp). Optimum values of circuit parameters have been derived for power efficient shifting of poles and zeros. The effect of placement of poles and zeros on dynamic settling error (DSE) is analysed by means of numerical simulation using MATLAB. This analysis will be useful to ascertain the relationship between pole–zero placements and settling time. The study of the effects of compensation elements on pole–zero placements has been done to assist the circuit designers to achieve better performance. Analysis of the effect of capacitive load on pole–zero placements and DSE has been done in this study. A technique has been developed to find out the upper and lower limits of compensation capacitor that allows fast settling with low power. The validity of the analytical work has been checked by simulation using Tanner tool in 0.35-µm CMOS technology. In the case of RNMC scheme, a power dissipation of 60.17 µw and a settling time of 340 ns are achieved; the results obtained are better than the earlier reported design technique. In the case of NMC, the simulation has been done to validate the analytical analysis.
Distributed Control Design for V2G in DC Fast Charging Stations

In this paper, an SoC-based droop control design is proposed for the vehicle-to-grid (V2G) operating mode of electric vehicles (EVs) in a DC fast charging station (DCFCS). The proposed primary control design aggregates EVs in the V2G mode while balancing EV batteries SoCs during charge and discharge modes to protect EVs from overcharge/overdischarge and increase the time duration at which all connected EVs are able to operate in the V2G mode. The proposed controller employs the output of a sigmoid function as the droop coefficient to allocate power among EV batteries. EV batteries’ energy capacities and SoCs are the variables in the sigmoid function. Compared to the conventional methods, the proposed controller balances SoCs without using the average SoCs to provide complete independence among chargers, considers the effect of different EV batteries energy capacities on the SoC balancing, and balances SoCs faster. The effectiveness of the proposed controller is evaluated through steady-state and transient case studies in the DCFCS with three EVs connected to chargers.
Calibration of laser vibrometer standards according to the standardization project ISO 16063-41

All users of primary calibration systems - excepting the national metrological institutes - are under obligation to trace back their reference standards - their Laser vibrometer standards - to their respective national standard if they intend to apply for (or maintain) accreditation or to strive for a very low measuring uncertainty for other reasons. A calibration method will be described in this paper that has been used by the accredited laboratory of SPEKTRA for calibrating a greater number of Laser vibrometer standards. All these calibrations proved the reliability and the very low measuring uncertainty of this method.
High transconductance enhancement-mode AlGaN/GaN HEMTs on SiC substrate

AlGaN=GaN high electron mobility transistors (HEMTs) are excellent candidates for high power and high frequency applications at elevated temperatures owing to their superior material properties [1–4]. To date, most of the efforts on GaN-based electronic devices have been directed towards depletion mode (D-mode) AlGaN=GaN HEMTs. However, some applications involving low-power digital circuits require the integration of both E-mode and D-mode HEMTs. Therefore, there is a great interest in the realisation of E-mode AlGaN=GaN HEMTs. Owing to the large polarisation charge in the AlGaN=GaN heterostructure, fabrication of GaN-based E-mode devices is more difficult compared to other material systems such as InP and GaAs. There have been only a few reports on these devices, and to date, the device performance is as yet unsatisfactory [5–7]. In this Letter, we report the fabrication of 1.0 mm gate-length E-mode AlGaN=GaN HEMTs grown by metal organic chemical vapour deposition (MOCVD) on SiC having a peak extrinsic transconductance of 248 mS=mm. These devices exhibited a current density of 470 mA=mm, a threshold voltage of 75 mV, an fT of 8 GHz and an fmax of 26 GHz. These results are significant improvements over previously reported GaN-based E-mode HEMTs.
Real-Time Motion Control of an Electric Driven OMR using a ROS to Matlab Bridged Approach

The ability to remotely monitor and track the location of autonomous mobile robots assures more control to the logistics companies, which guarantees the supply chain management is more efficient and secure. Therefore, many efforts and studies are focused on providing information about the current and past position of systems involved in the logistics chain, through the use of sensors and GPS-like systems. In recent years, Omnidirectional Mobile Robots are increasingly involved in complex industrial environments due to their navigation capabilities for complex trajectory planning together with task assignments.This paper presents an evaluation study of integrated development for an Omnidirectional Mobile Robot that is designed to serve in a dynamic logistic environment using Marvelmind Indoor Positioning System. The overall supervised system can be efficiently developed using Robot Operating System nodes, the path planning nodes benefiting from using Matlab-Simulink. This paper relates the work-in-progress of a real omnidirectional mobile robots (OMRs) platform subject to indoor localization with Marvelmind IPS network. This study emphasizes the need for consistent data taken from the sensors placed on the robot, the validation being a very important step for accurate robot localization.
Event-Triggered Deadbeat Control for HESS with Bidirectional Multiport Tri-Level Converter

This paper proposes an event-triggered deadbeat control (ETDBC) method for the hybrid energy storage system (HESS) in microgrid. The proposed method combines the event-triggered control strategy and the deadbeat control strategy, so that it possesses the advantages of rapid transient response and elimination of unnecessary operation. Hence it has the capability of maintain the satisfactory system performance and the low operational cost. Moreover, a bidirectional multiport tri-level converter (BMPTL) converter is adopted for the HESS in microgrids, which can integrate the HESS with one converter and reduce the ratings of the components. A digital model of the HESS using the BMPTL converter is built in Simulink to perform the various simulation studies. The comparison between the proposed ETDBC and the traditional deadbeat control method and the performance under the daily practical solar power generation have been conducted. The simulation results demonstrate the effectiveness of the ETDBC method for HESS integrated into microgrids via the BMTL converter.

Data were collected from manufacturing companies in Kocaeli, which is one of the greatest industrial regions of Turkey.
Status Report: Studies on Small Scale Testing Compared to Cal 133 Mockup Test

This study was triggered by the need for a simple laboratory scale ignition test to serve as a Quality Control Tool in conjunction with larger scale tests. Using the basic California Bulletin 117 (Cal 117) smoldering test configura tion, a number of variables have been screened in a composite ignition scenario to determine the feasibility of correlating with California Bulletin 133 (Cal 133) results. Variables studied included ignition source intensity (7), fabrics (6), and foams (6 types) ranging from standard furniture to high (flammability) per formance types. Results to date indicate feasibility of this approach.
Stress history effect on mining sand with fines contents

This paper presents the results of an experimental investigation of stress history on undrained shear characteristics of reconstituted mining sand with fines contents. The stress history and present state of stress which influence shear strength and deformation of soils are reflected by the overconsolidation ratio (OCR). A series of undrained triaxial tests were conducted on the reconstituted mining sand with clay fines specimens which were overconsolidated, in order to investigate the effects of stress history and clay fines on the stressstrainpore pressure response, peak strength and soil stiffness.
Study on Strength Characteristics of Reinforced Soil by Cement and Bamboo Chips

Soft ground with low bearing capacities is found to large areas in the world. In order to increase the bearing capacity of soft ground and to decreases settlement, some methods were developed for improving the mechanical properties of ground. As a stiffener of soil improvement, bamboo chips were used in this study. Bamboo is one of the fastest-growing plants on Earth and with a large distribution around the world. As a natural material, it is even better for environment and has excellently mechanical characteristic. The bamboo chips were mixed into the test specimen as a stiffener of soil improvement. Unconfined compression test were performed with test specimen, then mechanical characteristics of reinforced soil by cement and bamboo chips were investigated. From the test results, the strength and ductility characteristic of soil improvement are rather better when the bamboo chips are mixed.
The impact of e-service quality, customer satisfaction and loyalty on e-marketing: Moderating effect of perceived value

Since the online market has been growing rapidly over the past several years, electronic marketing activities have drawn a lot of attention. Many companies generated customer loyalty by improving electronic service quality (e-service quality) but the effects needed to be further examined. The first purpose of the study is to integrate relevant literature and develop a comprehensive research model of electronic commerce to identify its antecedent and consequential research variables. This study tests the interrelationships among the perception of e-service quality, customer satisfaction and customer loyalty. The second purpose of this study is to examine the moderating effect of customer perceived value on the relationship between customer satisfaction and loyalty. Through a questionnaire survey, the results of this study indicated that e-service quality has influence on customer satisfaction and then generates customer loyalty, which is consistent with Bagozzi's appraisal→emotional response→behaviour framework. Another key finding is the relationship between customer satisfaction and loyalty, which is stronger for customers with high perceived value than low perceived value. Conclusions indicate that website owners should not only improve e-service quality, but also emphasise customer perceived value.
Analyzing the effects of inventory cost setting rules in a disassembly and recovery environment

In this study we consider a disassembly and recovery facility receiving end-of-life products and facing demand for a specific part that is disassembled from the product and then recovered. The disassembly and recovery operations can be either performed before hand, or upon customer arrival. In the latter case, a discount on the selling price is applied to compensate the customer for waiting for the completion of the disassembly and recovery operations. One of the difficulties faced in planning for such a system is the determination of the opportunity cost associated with carrying recovered parts inventory. The difficulty arises in seeking the value added to the part given the costs incurred for maintaining the product return, disassembly and recovery costs and revenue earned from the hulk, that is the remaining product after the disassembly of the part. The main objective of the study is to investigate the effect of different rules to determine this opportunity cost on the performance of the system. Six rules are considered in the study. The performance of the rules is assessed by a computational study under an approximate inventory control policy.
Autonomous jumping robot with regulable trajectory and flexible feet

In this paper, a prototype of jumping robot with flexible feet is proposed to surmount obstacle efficiently. A six-bar adjustable mechanism for regulating jumping height and distance as well as a self-righting mechanism for uprighting after falling down are presented. The jumping height, jumping distance and energy conversion efficiency (ECE) are analyzed and tested, respectively, through dynamics modeling and jumping experiments. Taking advantage of flexible feet whose parameters are optimally designed, both the ground impulse acting on the robot and external kinetic energy relating to the movement of robot’s center of mass increase, so the performance of jumping height and distance as well as ECE of the robot with flexible feet is better than that of the one without flexible feet. By reducing leg mass and take-off angle as well as increasing stored energy, the external kinetic energy is enlarged, and ECE of the robot with flexible feet could be further improved. Meanwhile, simulation results show that the existing jumping robots which adopt four- or six-bar jumping mechanism are capable of enhancing jumping height and distance as well as ECE by exploiting flexible feet.
Prototype expert system for material selection of polymeric composite automotive dashboard

As a consequence of rapid development in material technology, determination of the right material for a given engineering application was viewed as a crucial decision. Various polymer materials selection methods have been developed to assist designers to determine the right polymer for a given engineering application. This paper presents a new natural fibre composite material selection process for automotive dashboard using expert system. The software tool chosen to assist the development of this expert system is PHPMyAdmin. The software tool was written in Hypertext Preprocessor (PHP) language designed to handle the administration of My Structure Query Language (MySQL) server over the World Wide Web. Various polymer composite properties are considered in order to develop the system. The focused properties of composites in this study are the density, Young’s modulus and tensile strength. In order to demonstrate the system implementation, a car dashboard has been selected as a case study. It has been shown that using PHPMyAdmin for polymer composite materials process can assist designers to determine the right polymer composites for a given engineering application.
Motorcyclist Protection Systems: Analysis of the Crash Test Tolerances of the European Technical Specification and the Spanish Standard

One of the most frequent and harmful kinds of motorcycle accidents is an impact against the post of the roadside barrier, so designers have developed some motorcyclist protection system (MPS) to reduce it. Some countries have developed a standard testing procedure, like the Spanish UNE-135900-2008 standard, identical to the CEN's recently approved Technical Specification (TS 1317-8). These standards specify the test procedure to obtain the behaviour of the MPS, but experimental tests have shown some dispersion of results for identical tests of the same barrier. There are some theories to explain this but the most reasonable is the influence of tolerances of some of the test variables in the final result like impact height, impact velocity, yaw angle, and mass. To analyze these theories, numerical analysis that can measure the independent influence of each parameter in the results has been used, using a correlated numerical model, a common and experimentally tested barrier, and an MPS. So, the results of this paper show how some parameters of impact significantly influence the behaviour of the system, changing impact severity, potential damage, and injuries. Therefore, the test tolerances do not guarantee repeatability and can accept systems too harmful for the same test conditions, so it will be necessary to reduce limit deviations of some impact variables.
Self-Balancing 3-phase 5-Level Flying E-Type Inverter for Photovoltaic Applications

This paper proposes a 3-phase 5-Level Flying E-Type Topology for photovoltaic applications, the converter is able to balance the voltage across the flying capacitors thanks to the modulation technique. The flying capacitor voltages are self-balanced without using any additional balancing circuits or closed-loop controls. Operation modes and characteristics of the proposed converter are presented, as well the voltage balancing approach based on the sinusoidal pulse width modulation scheme is explained. The analysis of the proposed converter has been validated through the digital-switching model realized in Matlab/Simulink environment. Preliminary results show the effectiveness of the proposed converter to balance the DC-bus voltage. Experimental tests on the converter prototype are illustrated.
Should Football Coaches Wear a Suit? The Impact of Skill and Management Structure on Serie A Clubs’ Performance

This paper implements the methodology proposed by Bell et al. (2013) for the English Premier League to test the performance of football club coaches in the Italian Serie A, so as to explore the robustness of this approach to a different setup. Our results show that, over the seasons 2011-12, 2012-13 and 2013- 14, only two coaches out of 49 outperform, three underperform, while the great majority performed as expected. It follows that conclusions about the appropriate sacking time are not easy and the final decision is determined by other circumstances. Although comparison with Premier League has to be taken with caution, our results show that, in the presence of the management structure and the tactical approach typical of Serie A, the model can pick up a few very extreme skill levels but it cannot differentiate among the great majority of coaches.
The Hidden Hazard of an Invisible Flame

A case study is presented of a fatal incident in which a man poured denatured alcohol on the wick of an alcohol stove with the intention of later lighting the wick, failed to first notice the wick had already been lit, and was engulfed in flames after the wick’s flame followed the stream of fuel into the can, and caused an explosion that spewed flaming fuel onto his torso. A survey was conducted to examine common knowledge about the invisible flame of burning denatured alcohol, and showed that none of the participants were aware that denatured alcohol burned with an invisible flame before the survey, and that a small percentage recognized it as a hazard after reading the product label. The incident is evaluated from the perspective of the manufacturer’s failure to guard users from the hazard of the invisible flame and their failure to warn users of the hazard.
Deep Learning models for Smart Building Load Profile Prediction

With the development in the sector of smart cities, smart buildings are becoming quite popular. For effective energy management of smart buildings, the accurate prediction of the electrical consumption data is required. To increase the accuracy of prediction, the paper proposes deep learning methods for load profile prediction in a model-free environment. In this paper, a commercial smart building load profile is predicted using the re-current neural network (RNN), long short term memory (LSTM), bidirectional LSTM (BiLSTM), and gated recurrent unit (GRU) model. Using the best features of RNN and BiLSTM a hybrid model is developed for the load profile prediction. To compare the performance of different models error metrics such as Root Mean Square Error (RMSE) and Mean Absolute Percentage Error (MAPE) are considered for performance evaluation. The paper also highlights the significance of hyperparameters in improving the accuracy of prediction. Finally, from the results, it can be claimed that the hybrid model performs better as compared to RNN, LSTM, and GRU models.
