Research on Talent Cultivation and Industry-Education Integration Path Construction of College Education under the Perspective of Informatization

Abstract This paper extracts the basic elements of the integration of industry and education under the perspective of symbiosis theory and builds a symbiosis model in the communication and cooperation between symbiosis units according to the symbiosis units in the system of integration of industry and education. Influential factors were screened from different levels, and the DEMATEL method was used to determine the importance degree of system factors in combination with the explanatory structural model so as to construct the structural framework of influential factors. The weights of the influencing factors were finally confirmed through analysis, and empirical research was conducted on three colleges and universities, S1, S2, and S3. The overall performance level of S1 college and university integration is excellent, and the comprehensive judgment value of the college and university integration performance of this college and university is 85.342. The overall performance level of the two colleges and universities, S2 and S3, is good, and the comprehensive judgment value of the college and university integration performance of the two colleges and universities is 77.933 and 81.930, respectively. The evaluation study on the integration of industry and education can provide better recommendations for the integration path.

Case study of the insulation performance in different types of flanking path construction

In many Asian countries, people often live in a high residential density environment due to the narrow land and dense population. As a result, It is common and unavoidable for noisy rooms and noise sensitive rooms to be adjacent (e.g., the audio-visual room is located under the living room of the upstairs residents). In order to improve sound insulation performance, feasible methods include improving direct and flanking sound transmission. Complete insulation performance research about has addressed different types of direct path construction in previous studies. However, to achieve higher insulation performance, the effect of the flanking path is key. The influence of the different flanking path constructions influence on sound transmission has rarely been explored. Therefore, this paper's objective is to study the overall insulation performance of different flanking path constructions (e.g., RC or lightweight construction), and the influence of adding additional layers. In this research, we focus on the vertical room pair situation and review direct and flanking path transmissions according to ISO 12354. Furthermore, we use the simulation software CadnaB to verify the influences of different types of construction, and then make a case in field measurements.

Intelligent Deep Learning and Softmax Routing for Energy-Efficient Wireless Sensor Networks in Public Space Design

The increasing usage of several nodes to transfer the massive volume of data to the remotes in wireless sensor networks is a challenging task to reduce the loss. The high volumes of data transmission in wireless sensor networks (WSN) can surpass their capacity, resulting in congestion, latency issues, and packet loss. However, computational intelligence (CI) models can aid in managing and creating intelligent networks in WSN. The WSN congestion issues result in information loss and increased energy usage. CI-based models have been used to resolve this issue, reducing the latency. This paper proposes SoftMax Routing with Deep Neural Network (SRDNN) for efficient routing in WSN. This will route the data packets by choosing the high energy and lower load. It consists of two parts, such as the construction of the routing path, which determines the residual energy of the node. It is analyzed using SoftMax routing to decide whether the node is efficient in energy. The route request and reply established various paths between the source and destination. The path with minimum buffer space and maximum bandwidth is chosen in the optimal routing. The simulation results under the metrics such as energy consumption, data loss rate, throughput, and delay show the proposed model performance.

GENDER-SPECIFIC LIFE SCENARIOS IN INDIVIDUALS WITH DIFFERENT LEVELS OF TOLERANCE TO UNCERTAINTY

Purpose. Currently, the scenario line of research in personality psychology seems to be particularly promising, since this line of research allows us to identify the specific features of the transformation of the conscious construction of human life paths under changing conditions of uncertainty. The aim of the study is to determine the gender specificity of life scenarios in individuals with different levels of tolerance to uncertainty.
 Materials and Methods. The sampling consisted of 200 people with different levels of tolerance towards uncertainty. The methods of the study included the semantic differential Lifestyle by V.P. Serkin and the New Questionnaire of Tolerance Towards Uncertainty by T.V. Kornilova. The data obtained were processed by means of factor analysis with the help of the program IBM SPSS Statistics 23.
 Results. The results showed that the life scenarios of people with different levels of tolerance to uncertainty are gender-specific: men with a high tolerance to uncertainty show predominant characteristics of the scenario associated with an active life position and the search for novelty, whereas women show a scenario aimed at activity in the social sphere (the desire to actively participate in the fate of others, to help and support). Men with a low tolerance towards uncertainty show such scenario patterns as striving for security, stability and predictability of events, while women – in addition to striving for a convenient, comfortable life – show tactical patterns: emotional restraint and calculation.
 Field of results application. The results of the study can be used in socio-psychological training and counselling to identify and correct an individual’s life scenario.

Cluster-Disjoint Multipath Routing Protocol for Real-Time and Reliable Packet Transmission in Wireless Sensor Networks.

Multipath routing protocol, which is one of the typical schemes to improve end-to-end transmission success ratio in Wireless Sensor Networks (WSNs), exploits two or more paths. However, collisions and interference might occur when each path is adjacent. To prevent this problem, they construct node- or link-disjointed paths. Although the paths could prevent the above-mentioned problem, it still has an issue in the area of time delay. To exploit the disjointed paths, pre-path construction is required. In addition, a lot of time is incurred to recover the whole path when the part of the path is damaged. This phenomenon adversely affects the end-to-end transmission success ratio and transmission time. To alleviate this problem, we propose a cluster-disjoint multipath routing protocol. The proposed scheme divides the whole network into grid clusters of a certain size in the network initialization phase. Each sensor could transmit packets through the pre-constructed cluster structure without the path construction phase. Also, even if any node fails, it could be easily replaced by other nodes within the cluster region. The simulation results show that the proposed scheme has an advantage in terms of transmission delay and end-to-end transmission success ratio compared to existing multipath routing protocols.

Port-Based Anonymous Communication Network: An Efficient and Secure Anonymous Communication Network.

With the rise of the internet, there has been an increasing focus on user anonymity. Anonymous communication networks (ACNs) aim to protect the identity privacy of users in the network. As a typical ACN, Tor achieves user anonymity by relaying user data through a series of relay nodes. However, this results in higher latency due to the transmission of network traffic between multiple nodes. This paper proposes a port-based anonymous communication network (PBACN) to address this issue. First, we propose a path construction algorithm. This algorithm describes constructing paths by partitioning the communication path information, which can reduce the probability of being discovered by adversaries. Secondly, we design a port-based source routing addressing method. During data transmission from the source to the destination, each node can directly forward the data by resolving the address into the port of each node. This method eliminates the need for table lookups, reducing the complexity of routing. Lastly, we propose an entropy-based metric to measure the anonymity of different ACNs. In terms of experimental evaluation, we quantitatively analyze the anonymity and end-to-end delay of various ACNs. The experimental results show that our proposed method reduces end-to-end delay by approximately 25% compared to Tor. When the adversary fraction is 20%, PBACN can improve the anonymity degree by approximately 4%.

Obstacle Adaptive Smooth Path Planning for Mobile Data Collector in the Internet of Things

In the edge-based Internet of Things (IoT) era, wireless sensor networks (WSNs) are the prime source for data collection. In such WSNs, mobile edge nodes such as mobile sinks (MSs) are the superior means to collect sensed data by visiting rendezvous points (RPs). However, WSNs are often obstacle-ridden, which creates hurdles to the movement of the MSs. Most of the existing path planning works dealing with obstacles do not address optimal and smooth path construction. In other words, they have not considered a) optimizing the number of RPs and constructing a feasible path and b) smoothing the constructed path by considering sharp edges and convexity of the obstacle perimeter. In this paper, we address all such issues and develop an efficient scheme for determining an optimal number of RPs using a greedy approach to the set-cover problem and optimized path construction, both in polynomial time. Then, we apply the modified BUG2 algorithm to construct an obstacle-free path, which is then smoothed using the concept of the Bezier curve. Extensive simulations show the superiority of our proposed scheme over the existing algorithms in terms of energy consumption, latency, and so on.

Captive Animal Behavior Study by Video Analysis.

Three video analysis-based applications for the study of captive animal behavior are presented. The aim of the first one is to provide certain parameters to assess drug efficiency by analyzing the movement of a rat. The scene is a three-chamber plastic box. First, the rat can move only in the middle room. The rat's head pose is the first parameter needed. Secondly, the rodent could walk in all three compartments. The entry number in each area and visit duration are the other indicators used in the final evaluation. The second application is related to a neuroscience experiment. Besides the electroencephalographic (EEG) signals yielded by a radio frequency link from a headset mounted on a monkey, the head placement is a useful source of information for reliable analysis, as well as its orientation. Finally, a fusion method to construct the displacement of a panda bear in a cage and the corresponding motion analysis to recognize its stress states are shown. The arena is a zoological garden that imitates the native environment of a panda bear. This surrounding is monitored by means of four video cameras. We have applied the following stages: (a) panda detection for every video camera; (b) panda path construction from all routes; and (c) panda way filtering and analysis.

PAtCH: Proactive Approach to Circumvent Holes in Wireless Sensor Networks.

The occurrence of hole regions in Wireless Sensor Networks is a significant challenge when applying a greedy technique in a geographic routing approach. The local minimum phenomenon is commonly attributed to physical obstacles, energy depletion of the nodes, failures in communication between neighbors, or even the incorrect deployment of the nodes in the sensing field. To address the problem of hole regions, most approaches choose to abandon the traditional greedy forwarding mechanism to temporarily adopt the well-known perimeter routing scheme applied to nearby nodes or along the edge of a region of a hole. However, this mechanism does not satisfy the network load balance requirement, because it imposes too much traffic to the nodes in the hole's edge, making them overloaded when compared to other network nodes more distant from holes. In this work, we propose a novel location-free geographic routing technique called PAtCH (Proactive Approach to Circumvent Holes in Wireless Sensor Network) to avoid routing holes in WSNs. Our solution can circumvent hole regions and create routing paths toward the destination. We consider that our sink has a higher communication range, and the Received Signal Strength Indicator (RSSI) is used to assist the construction of the routing paths. Our results show the efficiency achieved by our proposed solution in scenarios with hole regions, also maintaining all the benefits of a classic greedy forwarding technique.

Activation of Molecules H<sub>2</sub> on Platinum and Platinovanadium Clusters: Quantum-Chemical DFT Modeling

The NEB DFT/PBE0/def2tzvp quantum-chemical method with the construction of minimum energy paths (MEP) was used to study the activation of H2 molecules by Pt4 and Pt3V clusters. It is shown that, in the case of Pt4 and Pt3V clusters, barrier-free dissociative adsorption of H2 molecules occurs on platinum centers, while molecular adsorption of hydrogen occurs on the vanadium atom in Pt3V with a slight weakening of the H–H bond, but without its breaking. The noted features of the coordination of H2 molecules are explained at the level of the MO method. It has been established that the migration of the H atom from one cluster metal center to another in the considered model clusters, as, possibly, in the phenomenon of hydrogen spillover, occurs at small activation barriers in the direction of the displacement vector corresponding to the normal vibration of the system in the transition state. In the process of hydrogen migration, a significant role of Pt–H–Pt and V–H–Pt bridging groups, which facilitate the transition of H atoms from one metal center of the cluster to another, has been revealed.

Disjoint Paths Construction and Fault-Tolerant Routing in BCube of Data Center Networks

BCube is a promising structure of data center network, as it can significantly improve the performance of typical applications. With the expansion of network scale and increasement of complexity, reliability and stability of networks have become more essential. In this paper, we study the fault-tolerant routings in BCube. Firstly, we design a fault-tolerant routing algorithm based on node disjoint multi-paths. The proposed multi-path routing has stronger fault tolerance, since each path has no other common nodes except the source node and the destination node. Secondly, we investigate an effective fault-tolerant routing based on routing capabilities algorithm for BCube. The proposed algorithm has higher fault tolerance and success rate of finding feasible routes, since it does not limit the faults number. Thirdly, we present an adaptive path finding algorithm for establishing virtual links between any two nodes in BCube, which can shorten the diameter of BCube. Extensive simulation results show that the proposed routing scheme outperforms the existing popular algorithms. Compared with the state-of-the-art fault-tolerant routing algorithms, the proposed algorithm has a 21.5% to 25.3% improvement on both throughput and packet arrival rate. Meanwhile, it reduces the average latency of 18.6% and the maximum latency of 23.7% in networks.

ON THE EXPECTED UNIFORM ERROR OF BROWNIAN MOTION APPROXIMATED BY THE LÉVY–CIESIELSKI CONSTRUCTION

AbstractThe Brownian bridge or Lévy–Ciesielski construction of Brownian paths almost surely converges uniformly to the true Brownian path. We focus on the uniform error. In particular, we show constructively that at level N, at which there are $d=2^N$ points evaluated on the Brownian path, the uniform error and its square, and the uniform error of geometric Brownian motion, have upper bounds of order $\mathcal {O}(\sqrt {\ln d/d})$ , matching the known orders. We apply the results to an option pricing example.

The pipelines and cable trays location problem in naval design

This paper deals with the determination of optimal locations for pipelines and cable trays in naval design. The problem consists of finding the number and types of cable tray routes to be created between various devices in order to minimize a user defined cost function. We reduce the problem to an ad hoc min-cost multicommodity flow problem with additional constraints imposed by technical requirements. This problem is solved for small-sized instances by using off-the-shelf optimization solvers. We also develop an exact relax-and-cut strategy that allows to handle medium-sized instances. For larger instances, we propose a family of heuristic algorithms consisting on the combination of two phases: (I) Construction of initial cable trays paths; and (II) Transformation to feasible cable trays verifying the technical requirements. For each of them, we also propose different strategies which give rise to several algorithms. These algorithms are compared on a computational experience using two types of instances: the first one based on random instances of different sizes and the second one based on instances with well-defined corridors to asses the availability of our methodology to enforce the creation of cable trays. Finally, we also analyze a real size case study provided by our industrial partner, Ghenova, a leading Naval Engineering company, validating our proposal to find solutions for this problem.

Background oriented schlieren image displacement estimation method based on global optical flow

Background oriented schlieren (BOS) technology is a recent non-contact optical diagnostic technology, which can be used for the visualization of variable density flow and the quantitative measurement of the refractive index field. The accuracy of BOS image displacement estimation directly determines the accuracy of refractive index field reconstruction. For BOS images, the optical path construction method, vibration and uneven illumination, blurring and defocusing effects, and the refocusing effect of volume refraction make it difficult for the BOS image sequence to satisfy the constant brightness assumption. In this study, the optical flow algorithm based on the assumption of a constant gradient in PIV is improved and applied to BOS image displacement estimation. A data item based on the assumption of constant brightness combined with the assumption of constant gradient is proposed. The first-order div-curl regularization constraint is used as the spatial smoothing condition, and the non-convex Charbonnier penalty function is used to determine the displacement field by the variational method to minimize the energy function. The proposed method is tested on the synthetic images obtained by two-dimensional turbulent direct numerical simulation (DNS), the BOS synthetic images with brightness changes, and the actual experimental BOS images of the flow field above a premixed butane/air combustion flame with different equivalence ratios. Compared with the current advanced optical flow algorithm, this method has higher accuracy and robustness. Overall, the proposed method can not only obtain more accurate results when the brightness of the BOS synthetic image and experimental image changes, but also helps in retaining the flow details such as small divergence and vorticity structure of the heat flow field while reducing the outliers.

Research on the integration development path of rural tourism and traditional culture protection and inheritance based on the integration of big data

Abstract This paper studies the integration and development of rural tourism and cultural preservation and inheritance, aiming to explore new development paths for rural tourism. This paper first introduces the basic algorithm and steps of plain Bayesian, and the fusion improves the principal kernel components of the Bayesian model. Using the improved plain Bayesian model to analyze rural tourism and traditional culture protection and inheritance, the problems in the integration process are analyzed from the rural cultural tourism situation, the integration of rural tourism and cultural protection and inheritance, as well as the proposed integration development countermeasures and the construction of the integration development path. In the study of the integration situation, the single indicator of infrastructure construction under the development level system reaches 0.9578, ranking first in the ratio of all three indicators, indicating that infrastructure construction is the most important factor affecting tourism development. Policy support and the construction of the six elements of tourism ranked second at 0.453, indicating its importance. Regarding countermeasures, 90% believe that cultural heritage buildings should be protected, 95% believe that cultural connotations should be deeply explored, and 85% believe that the integration of culture and tourism should be strengthened. Integrating rural tourism and traditional culture preservation is a long-term process that requires continuous exploration and improvement.

Dataplane-Based Fast Failover in SDN-Enabled Wide Area Measurement System of Smart Grid

In the wide area measurement system (WAMS) of smart grid, the real-time monitoring and protection applications have stringent requirements for the end-to-end transmission delays between PMUs and PDC, and fast failover is required to ensure the communication performance after link failures. In this work, the software-defined network (SDN) technology is utilized to enable datapath failover upon a link failure with a global view of the communication network. Then, a novel dataplane based fast failover (DFF) mechanism is proposed to <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">directly</i> re-route the data packet in dataplane without interacting with the SDN controller. Based on the mathematical analysis over the WAMS topology features, the proposed DFF optimizes two procedures of failover: backup path construction, and backup path installation. Using the proposed backup path construction algorithms, the 3-approximate and (1+2 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$\varepsilon$</tex-math></inline-formula> )-approximate ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$0&lt; \varepsilon &lt; 1$</tex-math></inline-formula> ) backup paths can be constructed, theoretically guaranteeing the data transmission delays both <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">during</i> and <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">after</i> failover. Using the proposed LinkID-based FF group table installation method, the conflict of forwarding rules between original and backup paths can be eliminated, while the storage cost is also optimized. The simulation results on six IEEE benchmark test power systems show that the proposed DFF mechanism could achieve lower data transmission delays during and after failover compared to the existing control plane based and dataplane based failover mechanisms.

THE CONTENT AND COMPONENTS OF STUDENTS’ EARLY PROFESSIONAL SELF-DETERMINATION IN THE SYSTEM OF SECONDARY EDUCATION

In this article, the content and components of students’ early professional self-determination in the system of secondary education were studied. The theoretical analysis of the study’s main directions of professional self-determination – structural theories, motivational theories, theories of individuality – made it possible to define professional self-determination as a step-by-step process leading to a successful and conscious career building. It was revealed that the process of self-determination should be carried out in the middle level of the school. The authors proposed the definition of early professional self-determination as a process of personality development, expressed in the conscious construction of a future professional path, considering the needs, motives, interests and inclinations of students, in accordance with the socio-economic conditions of the professional environment. To determine the structure of early professional self-determination (its components), we conducted an online survey among secondary school students in Pavlodar region using a Google form. The survey involved 2968 students in grades 7-9, gender was not considered. Based on the results obtained, the components of early professional self-determination were identified: motivational-value component (personal interest, salary), reflexive-evaluative component (inclinations, abilities), social component (parents, teachers, friends, classmates, popularity of the profession). Thus, these components of early professional self-determination should be directly interconnected and complementary, resulting in a conscious, realistic, desired choice and a plan for immediate actions for personal and professional development.
