On the issue of the special structure of multiplevalued trigger with multiple-rail-output, a synchronous edge-triggered improved ternary JK flip-flop with three-rail output structure is presented based on the negative differential resistance (NDR) characteristic and the literal operation as well as the module operation. The ternary NDR JK flip-flop could set the logic values of the output to realize...
Photoperiod is an important factor to the inducing plants flowering. This paper presents the analysis in the photoperiodic reaction types approaches of plant flowering. It is pointed out that the photoperiod plays an concrete role in application of plant flowering. Meanwhile, other environment factors are needed to be considered. In order to make the effective development in agricultural planting...
Telehealth implementations are often inadequately evaluated, due to selective focus of interest and limited analysis of individual factors. This paper provides an appraisal of some generic approaches to evaluating telehealth implementations, based on a survey of contributions in the literature. Some strengths and limitations of existing approaches are identified. Adoption of a framework-based strategy...
Hardness sensing is a valuable capability for a robot touch sensor. We describe a novel method of hardness sensing that does not require accurate control of contact conditions. A GelSight sensor is a tactile sensor that provides high resolution tactile images, which enables a robot to infer object properties such as geometry and fine texture, as well as contact force and slip conditions. The sensor...
Interactive news recommender systems allow the user to steer the received recommendations in the desired directions through explicit interaction with the system. It provides a user experience in between a “lean back and let the news wash over me” experience and an “active search and hunt for specific pieces” experience. On the other hand, this added level of interaction might also be perceived as...
A number of communications in the work of the informative sites of leading scientific organizations of the Russian Federation, including in the structure of the Russian Academy of Sciences and Federal Agency of Scientific Organizations is researched.
Data visualizations have become an integral role for management system. It not only allows users to witness, explore and understand large amounts of information, but also convey information more directly expressed. This paper presents how to use JavaScript third-party library such as Flot and D3.js for collection, analysis, processing and visualization of data by using Ajax.
Each airborne heat exchanger vibration test has very high dynamic performance requirements for the fixture used by it. Mode analysis of some airborne heat exchanger was carried out using the ANSYS software on the basis of the finite element modal analysis method's theory, so as to identify the fixture's natural frequency. In addition, the effectiveness and accuracy of the finite element modal analysis...
In this paper, the relationship between the distance metrics and the data model was analyzed and a new algorithm for keystroke dynamics classification was proposed. The results of the experiments on the CMU and GREYC keystroke dynamics benchmark and mobile devices datasets were evaluated. The classifiers using the proposed algorithm outperform existing top performing keystroke dynamics classifiers...
A kind of closed hydraulic system controlled by servo motor and constant pump is introduced for controlling the experimental press. By using AMESim and Adams, the hydraulic system model and motion model of the beam of the experimental press are established and co-simulation is carried out. PID controller is used in this hydraulic system to improve the control performance. Simulation results indicate...
Servo mechanical press is a complicated system with several transmission processes. The friction and other nonlinear factors are critical problems of servo press controlling. This paper focuses on the performance improvements of position tracking on servo press. In order to carry out the researches, first, the mathematic model which expresses the mechanical transmission processes is built to analyze...
Unidirectional proportional pump-controlled asymmetric cylinder systems are widely used on industry machines, but the analysis and synthesis of such systems is very hard due to the nonlinearity caused by the different working areas of cylinder piston. The limit of one-way flow control ability of the pump and the working pressure make the problem more complex. It is very hard to find an effective method...
The given paper depicts a conducted analysis of special positions of manipulation systems basing on the parallel structure mechanisms used in aggressive media. Motional systems of these mechanisms are not located within the border of an operational zone, with this aim a development of algorithms is requested for withdrawal of mechanisms from special positions. The obtained research results can be...
In response to national policy for energy conservation and emissions reduction which require the appearance of new type of fly ash brick molding machine. Hence, it's exigent to explore substitute for the early brick machine. New type of fly ash brick molding machine is an automatic machine which is used to produce high density bricks with coal ash. It is good for energy saving and environmental protection...
In this two-hour workshop, we propose leading a discussion of an important, yet underinvestigated, facet of entrepreneurial communication: pitching. Specifically, we will discuss formal pitching, storytelling, and written elements of the pitch. We will do this by drawing on our own research, other published research, rhetorical theory, management theory, and our experience. Audience members will learn...
Direct growth of graphene by industrially scalable methods on suitable dielectric substrates is critical to the development of practical electronic and spintronic devices. Graphene growth by molecular beam epitaxy on the commensurate substrate h-BN(0001) and on other weakly interacting substrates has previously been demonstrated. We have been able to use MBE to grow graphene on incommensurate Co3O4(111),...
The aim of this research is to study behavior of numerical methods for solving one-dimensional stationary Schr¨odinger equation. Two testing tasks are taken for example: the probability tunneling of the square potential barrier and “hyperbolic” potential barrier. The precision and speed of various methods were evaluated.
Educational opportunities in the field of biomedical engineering and biomedical technician have been increased today. The concept of clinical engineering was born and gain a rapid development stage due to the employment of personnel trained in this area in health facilities. The importance of clinical engineering units that provide or control purchasing of medical equipment, checking and acceptance...
