Optimization of Railway Mixed Goods Loading Layout considering Stability.

It is well known that stability, center-of-gravity balance, and concentrated-weight are key factors of the transportation safety. The reasonable formulation of the loading layout scheme ensures the safety of shipment based on fully utilizing the effective volume and load capacity of freight vehicles. This paper takes the railway mixed goods loading layout as the research object, considering the constraints such as goods loading center-of-gravity balance, the allowable moment of concentrated-weight, supporting and goods placement mode, and taking the maximum comprehensive utilization rates for both effective volume and load capacity of freight vehicle as the optimization objective, an optimization model of railway mixed goods balanced and anticoncentrated-weight loading layout considering stability is built. Additionally, this paper designs mixed goods classified and simple/general goods block composition methods. We improve the representation and selection of layout space, construct goods block selection algorithm based on the greedy d-step lookahead tree search and goods block evaluation function and propose a goods block placement strategy and update rules of layout space after goods block placement. An optimization algorithm of railway mixed goods balanced and anticoncentrated-weight load layout considering stability is designed. The results show that the formulated scheme not only ensures that the goods meet the full support constraints, but also the comprehensive utilization rate of the effective volume and load capacity of the vehicle is not less than 89%, and the probability of meeting the loading center-of-gravity balance and allowable moment of concentrated-weight are as high as 99% and 99.47%, respectively. The proposed method realizes the balanced and anticoncentrated-weight loading of railway mixed goods, ensures the safe, stable, and efficient goods loading, and provides decision support for the safe loading layout of railway goods.

Spatio-Temporal Variation and Influencing Factors of the Coupling Coordination Degree of Production-Living-Ecological Space in China.

Territorial space is a multi-functional complex. The coordinated production-living-ecological space (PLES) effectively coordinates the man-land relationship, promotes regional sustainable development, and maximizes territorial space. How to build a high-quality national spatial layout and support system for development has become a hot topic of concern in all sectors of society. However, few studies have explored the coupling coordination considering the various production-living-ecological functions of land use type and its influencing factors of PLES at the county scale in China. To address the gap, based on the connotation of PLES theory, this study established a classification and evaluation system for PLES and analyzed the spatio-temporal characteristics, coupling coordination degree, spatial autocorrelation, and influencing factors of PLES in China from 2000 to 2020. The results are as follows: (1) The production space index and living space index in China showed a continuous increase tendency, while the ecological space indexs decreased continuously during the study period. The production space and living space were concentrated in the east of Hu Line, and the ecological space indexes in mountainous areas were significantly higher than those in plain areas during the study period. (2) The gravity centers of PLES all migrated to the west of China to different degrees during the study period. (3) From 2000 to 2020, the basically balanced category was the main coupling coordination type, and the number of seriously unbalanced categories accounted for the least. In the west of the Hu Line, the seriously unbalanced category was dominant, while in the east of the Hu Line were the moderately unbalanced categories and above. (4) During the study period, the low-low type was the main relationship type, widely distributed in western China, followed by the high-high type, mainly situated in the North China Plain, Yangtze River Delta, Pearl River Delta, Jianghan Plain, Chengdu Plain, Northeast China Plain, and some provincial capital cities. (5) Regression results showed that natural factors were the main reason restricting the coordinated development of PLES, and socioeconomic factors could effectively promote the coordinated development of PLES. Landscape pattern also significantly influenced the coordinated development of PLES, but varied greatly. The findings of this study can provide a scientific reference for the optimization of territorial space layout and the promotion of high-quality development of territorial space.

Research on the Equity of Urban Green Park Space Layout Based on Ga2SFCA Optimization Method—Taking the Core Area of Beijing as an Example

(1) Background: The issue of equity in the layout of urban green park spaces is an essential dimension of urban public resource allocation. (2) Objective: To analyze the equity of the distribution of parkland in the core area of Beijing from a quantitative and spatial perspective. By measuring both vehicular and pedestrian transport modes, the study identifies areas with low levels of green space provision and provides strategies for optimization. It is hoped that this study can provide a basis for future green space construction in the core area of Beijing. (3) Methods: In this paper, the Gauss Two-step Floating Catchment Area Method (Ga2SFCA) is used to study the green park space layout in the core area of Beijing. The two modes of 30min-walk and 10min-car-journey were used to measure the fair values of the residential unit scale, the street district scale, and the overall scale, respectively. (4) Results: The study results show that the fair values based on the 30-min walk and the 10-min car journey differ significantly. For the 30-min walk-based travel mode, the proportion of fair (Class IV) and fairer (Class V) areas is approximately 20%, while for the 10 min car-based travel mode, the corresponding class is over 90%. (5) Conclusions: The overall equity of urban parkland in Beijing core area is better for car-based travel modes, while for walking modes, the supply is still insufficient, and the distribution of parkland is polarized.

Construction of water space characteristics in Yuanjiang City based on urban water management framework

ABSTRACT Taking the water space landscape in the city as the theme, the relationship between city and water as the core, and Chinese traditional culture as the ideological context, this paper puts forward the theoretical framework and practical cases of urban water management. Urban water management theory provides corresponding theoretical support for the construction of water characteristics and guides practice in many aspects, including water ecology, water environment, water safety, water cycle, water culture, water space and water economy, to optimize the structure and function of the water space. It is necessary to explore measures for constructing water space features from the standpoint of ecological security patterns, urban and rural quality improvement and feature shaping, central urban space layout, and regional coordinated development. The research on the land spatial planning method of waterfront cities proposed by this study can provide new ideas for the spatial land planning of other waterfront cities.

Experimental and theoretical study on flexural behaviour of a new UHPC sandwich slab

In this study, a new type of prefabricated ultra-high performance concrete (UHPC) sandwich slab is proposed, which is composed of UHPC layer at the top and bottom, short UHPC columns and extruded polystyrene foam board (XPS) in the middle layer. The load-bearing and thermal-insulation integrated sandwich slab shows much lower self-weight and less reinforcement than traditional concrete slab, which are very beneficial for construction of precast structures. This paper first presents a reasonable and reliable casting method for the new sandwich structure. Then four-point bending tests on five slabs are conducted to reveal their flexural performance. The investigated parameters include the thickness of the UHPC layer, reinforcement ratio, short column spacing and XPS layout. Test results demonstrate that this type of sandwich slab, with 4500 mm span length, 150 mm thickness and one-way simply supported condition, has excellent anti-cracking and flexural performance, which can sustain an additional uniformly distributed load more than 9 kN/m2 before cracking even without reinforcement. A small ratio of reinforcement 0.13% in the bottom layer can further improve the ultimate bearing capacity by 20% and ultimate deformation by 61%. Finally, the calculation methods of cracking load, peak load and stiffness are proposed, together with design suggestions for typical slab dimensions, which offers valuable guidance for practical engineering.

3D Space Layout Design of Holographic Command Cabin Information Display in Mixed Reality Environment Based on HoloLens 2.

After the command and control information of the command and control cabin is displayed in the form of mixed reality, the large amount of real-time information and static information contained in it will form a dynamic situation that changes all the time. This brings a great burden to the system operator’s cognition, decision-making and operation. In order to solve this problem, this paper studies the three-dimensional spatial layout of holographic command cabin information display in a mixed reality environment. A total of 15 people participated in the experiment, of which 10 were the subjects of the experiment and 5 were the staff of the auxiliary experiment. Ten subjects used the HoloLens 2 generation to conduct visual characteristics and cognitive load experiments and collected and analyzed the subjects’ task completion time, error rate, eye movement and EEG and subjective evaluation data. Through the analysis of experimental data, the laws of visual and cognitive features of three-dimensional space in a mixed reality environment can be obtained. This paper systematically explores the effects of three key attributes: depth distance, information layer number and target relative position depth distance of information distribution in a 3D space, on visual search performance and on cognitive load. The experimental results showed that the optimal depth distance range for information display in the mixed reality environment is: the best depth distance for operation interactions (0.6 m~1.0 m), the best depth distance for accurate identification (2.4 m~2.8 m) and the overall situational awareness best-in-class depth distance (3.4 m~3.6 m). Under a certain angle of view, the number of information layers in the space is as small as possible, and the number of information layers should not exceed five at most. The relative position depth distance between the information layers in space ranges from 0.2 m to 0.35 m. Based on this theory, information layout in a 3D space can achieve a faster and more accurate visual search in a mixed reality environment and effectively reduce the cognitive load.

Parameter Optimization and Application of Gas Extraction Technology by Buried Pipes in Goaf of Multi-roadway U-type Working Face

ABSTRACT The gas extraction method by buried pipes in closed connection roadways of goaf was proposed. It was intended to solve large gas emission quantity and over-limit gas concentration at the upper corner in the goaf of highly gassy mine. The study object was 81307 fully mechanized mining face in Baode Coal Mine. The gas distribution characteristics in the goaf during no extraction and those during gas extraction by buried pipes under different extraction parameters were numerically simulated via COMSOL Multiphysics, and the best layout parameters of buried pipes in the goaf were determined. A field optimization experiment was carried out for the extraction parameters. Results showed that the extraction measure by buried pipes could effectively solve the aforementioned over-limit gas concentration at the upper corner when the layout spacing of closed connection roadways was 100 m, extraction pressure was −32 kPa, diameter of extraction pipe was 800 mm, and extraction flow was 600 m3/min. During the experiment, the average gas concentration at the upper corner was 0.38% and that in the return airway was 0.29%. Both of which were lower than the national safety standard, thus reaching the goal of safety production.

Smart Home Product Layout Design Method Based on Real-Number Coding Genetic Algorithm.

Aiming at the problems of poor layout design efficiency of smart home products and low rationality of layout planning, a layout design method for smart home products based on a real-number coding genetic algorithm is proposed. The principles of smart home product layout design are analyzed and the smart home system architecture based on the Internet of Things is designed. Divide the combination of smart home product layout space according to spatial function, extract the visual features of smart home product layout, build a smart home product layout optimization model based on the two constraints of the total area and individual area of smart home product spatial layout, and design a real-coded genetic algorithm. The model is solved to improve the global convergence of the algorithm, and the optimization method for the layout of smart home products is obtained. The experimental results show that the layout design method of smart home products based on a real-number coding genetic algorithm can accurately extract the layout features of smart home products and accurately classify the number of pairs of homes. The efficiency of layout design and rationality of layout planning of smart home products are better, which reflects the effectiveness of this method.

Urban morphology parameters towards multi-risk scenarios for squares in the historical centers: Analyses and definition of square typologies and application to the Italian context

• Historical squares are prone to multi-risks depending on their physical features. • A methodology for defining physical features relevant for multi-risks is proposed. • Physical features of squares are quantitatively identified into parameters. • Identified parameters are tested on case studies for further detailing and testing. • Parameters describe squares typologies performance to multi-risks scenarios. The historical built environment (HBE) in urban areas is prone to disasters, which threaten both people and the historical built heritage itself. In such a scenario, risks depend on the combination between different possible (multi-) hazards (including climate change-related ones), the vulnerability and exposure of HBE users, and the physical (morphology-, typology- and construction-related) features of the HBE. In this context, squares are relevant components of the HBE from a meso‑scale perspective, which is based on the layout and morphology of open spaces, buildings blocks and their users. Squares host cultural heritage and attract users, both tourists and citizens. Moreover, squares are nodal points for the emergency path network and are crucial and significantly affected during the immediate aftermath of the disaster occurrence (e.g. by debris on the ground in the case of seismic hazard during the evacuation phase). Current approaches for risk assessment and mitigation entail the consideration of each specific square, but this approach is time-consuming, scattered between the different hazards and complex to apply to a multi-risk perspective. Therefore, this work provides a methodology to identify and classify the most relevant physical features of squares in the HBE, which are able to improve or worsen the performance of the HBEs to multi-risks from multi-hazard scenarios. The research is rooted in the existing literature and strengthened by experts’ judgement analyses. The proposed methodology synthesizes the considered relevant features of the squares in the HBE into quantitative parameters, which allow to verify the vulnerability to multi-risk of the squares. Such parameters are further organized into classes for the typological assessment of the multi-risk. To test and detail the parameters, the method is tested on a relevant case study, which is the Italian context. Indeed, such a case study is relevant not only for being subject to multi-risks (e.g., seismic, terrorist, heatwave and air pollution), but also because the vast majority of the urban areas are composed by HBEs and hosts cultural heritage sites. Moreover, in this context, squares have not only an environmental, but also a social and economic importance in the HBE and are thus particularly relevant. Then, in the relevant case study of Italy, further detailing and calibration of the defined classes of the relevant parameters, as well as their ranges, are tested on 133 squares, which cover the entire Italian territory. Results demonstrate that the identified classes and ranges of the parameters are suitable for describing historical squares by arranging them into typologies for multi-risks assessment. Although the parameters are here presented for the Italian context, they are of general value and could be tested in other contexts, by calibrating the ranges as illustrated for the specific considered sample. Thus, the outcomes of this work allow moving towards the classification of squares into built environment typologies according to the meso‑scale perspective, provide the bases for and promoting the application of expeditious approaches to multi-risk assessment in the HBE.

An In-Depth Survey of Bypassing Buffer Overflow Mitigation Techniques

Buffer Overflow (BOF) has been a ubiquitous security vulnerability for more than three decades, potentially compromising any software application or system. This vulnerability occurs primarily when someone attempts to write more bytes of data (shellcode) than a buffer can handle. To date, this primitive attack has been used to attack many different software systems, resulting in numerous buffer overflows. The most common type of buffer overflow is the stack overflow vulnerability, through which an adversary can gain admin privileges remotely, which can then be used to execute shellcode. Numerous mitigation techniques have been developed and deployed to reduce the likelihood of BOF attacks, but attackers still manage to bypass these techniques. A variety of mitigation techniques have been proposed and implemented on the hardware, operating system, and compiler levels. These techniques include No-EXecute (NX) and Address Space Layout Randomization (ASLR). The NX bit prevents the execution of malicious code by making various portions of the address space of a process inoperable. The ASLR algorithm randomly assigns addresses to various parts of the logical address space of a process as it is loaded in memory for execution. Position Independent Executable (PIE) and ASLR provide more robust protection by randomly generating binary segments. Read-only relocation (RELRO) protects the Global Offset Table (GOT) from overwriting attacks. StackGuard protects the stack by placing the canary before the return address in order to prevent stack smashing attacks. Despite all the mitigation techniques in place, hackers continue to be successful in bypassing them, making buffer overflow a persistent vulnerability. The current work aims to describe the stack-based buffer overflow vulnerability and review in detail the mitigation techniques reported in the literature as well as how hackers attempt to bypass them.

A study on the strategies of Park City construction of Chengdu from the perspective of urban heat island mitigation

In the process of urbanization, various urban problems have become increasingly prominent, and the heat island effect is one of them. The expansion of urban land, the increase in construction intensity and the increase in population make the urban heat island effect even worse. The construction of park cities improves the ecological environment of the city and is considered to have a positive effect on alleviating the heat island effect, but it is not clear whether it has such an effect or not. This article explores whether the construction of Park City can help to improve the urban thermal environment effectively, and also, seek solutions for how to improve the construction of park cities so that the heat island effect can be better mitigated. Landsat8 remote sensing images in 2014 and 2019 were used to estimate the fractional vegetation cover (FVC) and land surface temperature (LST) in the Third Ring Road of Chengdu. Land use data were also introduced into the study to analyze LST changes in different surfaces and FVC.The results indicate that: (1) the area of the heat island zone in the Third Ring Road of Chengdu decreased by 0.91% from 2014 to 2019, and the area of the cold island zone increased by 17.89% ; (2) the urban blue-green space is conductive to mitigating the urban heat island effect, in which the water provides the best mitigation, while impervious surface and bare land may aggravate the urban heat island effect; (3) the FVC in the area of the Third Ring Road in Chengdu is on the rise as a whole, and there is a significant negative correlation between FVC and LST (p < 0.01). Based on the above results, this paper shows that Park City construction is beneficial to alleviate the urban heat island effect, and more attention should be paid to blue-green space layout and quality, along with urban ventilation and FVC control. Our results provide useful input for green space planning and the construction of Park City in the future.

O-097 Building the perfect cleanroom IVF lab and maintaining it

Abstract Designing and installing a new ART laboratory is not something one does every day and the challenges one faces are many. Putting together a planning team with all concerned parties and stakeholders already in the very early phase of the project is crucial. The aim of the planning team is to critically consider all wishes and requirements, to weigh all the pros and cons and make realistic choices. The final scenario should comply with regulations and/or legislation. This implicated that IVF laboratory facilities should be constructed according to cleanroom regulations to control air-borne contaminants. The construction costs of laboratory space per square meter is about the same as the cost of an operating room. That's why it's so important to discuss space needs and layout well in advance in the planning team. To avoid future bottlenecks during operation, is might be wise to construct multifunctional facilities i.e. an room dedicated to embryo replacements can be designed without much extra cost in such a way that it is also suitable for performing egg retrieval if necessary. Once the cleanroom is build and the HVAC is working, compliance with the designated classification has to be demonstrated in the formal process of qualification (or validation). Provide enough space for cryostorage. This storage room should be a dedicated, locked room ideally not too far from the laboratory cleanroom and should be easily accessed for liquid nitrogen supply. As an alternative, a centralized liquid nitrogen distribution via a vacuum isolated pressured line (VIP) can be considered. One of the most important choices in terms of space requirements and layout is the type and number of workstations, equipment and incubators. Once the number and exact types are known, their exact position should be drawn on the plans in order to determine the necessary outlet points for medical gasses, electricity plugs and network connections.

On Random Number Generation for Kernel Applications

An operating system kernel uses cryptographically secure pseudorandom number generator (CSPRNG) for creating address space layout randomization (ASLR) offsets to protect memory addresses of processes from exploitation, storing users’ passwords securely and creating cryptographic keys. However, at present, popular kernel CSPRNGs such as Yarrow, Fortuna and /dev/(u)random which are used by MacOS/iOS/FreeBSD, Windows and Linux/Android kernels respectively lack the very crucial property of non-reproducibility of their generated bitstreams which is used to nullify the scope of predicting the bitstream. This paper proposes a CSPRNG called Cryptographically Secure Pseudorandom Number Generator for Kernel Applications (KCS-PRNG) which generates non-reproducible bitstreams. The proposed KCS-PRNG presents an efficient design uniquely configured with two new non-standard and verified elliptic curves and clock-controlled Linear Feedback Shift Registers (LFSRs) and a novel method to consistently generate non-reproducible random bitstreams of arbitrary lengths. The generated bitstreams are statistically indistinguishable from true random bitstreams and provably secure, resilient to important attacks, exhibits backward and forward secrecy, exhibits exponential linear complexity, large period and huge key space.

Capacity Analysis of Vehicle Parking Area in "Terminal Petikemas Surabaya"

Parking is one element of the means that cannot be separated from the overall road transportation system. Parking is a problem that is often found in urban transportation systems both in big cities and in developing cities. The reality that often occurs is that the condition of vehicle parking, including the misuse of the function of the parking space, improper and inadequate arrangement of facility layouts, causes undisciplined vehicle users. To determine parking facilities at a location, a good standard parking requirement is needed so that the parking space provided can accommodate the parked vehicle according to its purpose. This study is located at PT. Surabaya Petikemas Terminal, Perak Barat, Krembangan District, Surabaya City, East Java. The method applied in this study is to conduct a direct survey in the field including recording vehicles entering and leaving to get vehicle data.

The number of newly added cultural spaces and the expansion speed show an increasing trend, expanding at an average annual speed of about 35 km2, effectively increasing the quality of regional planning and construction layout.

SPATIAL EQUITY OF CITY PUBLIC OPEN SPACES BASED ON G2SFCA: A CASE STUDY OF WUHAN, CHINA

Abstract. Urban public open spaces refer to open space between architectural structures in a city or urban agglomeration that is open for urban residents to conduct public exchanges and hold various activities, and their spatial distribution characteristics are important indicators to measure the sustainable development of urban ecological society. Therefore, it is important to evaluate the rationality of urban public open space layout for practical guidance. Address this problem, taking Wuhan as an example, this paper uses high-resolution grid population density data and web map API to construct an evaluation system for the spatial equity of urban public open spaces based on the accessibility index calculated from G2SFCA. The results showed that the layout of public open spaces in Wuhan is not reasonable, and there are significant spatial differences in the accessibility index of different types of public open spaces, as well as a certain degree of imbalance between them and the spatial distribution of population, indicating that there is a "mismatch" and "dislocation" in the supply-demand relationship of public open spaces in Wuhan. These results explain the fairness of public open space layout in Wuhan and provide a scientific basis for a more reasonable and equitable allocation of urban public open spaces in Wuhan.

Research on Traffic Design of Urban Vital Streets

As an important part of urban public spaces, the urban street is an important place for people’s lives, communication, and activities. Its vitality directly affects the vitality of the whole city. It is of great practical significance to examine the current situation and theoretical development of urban streets in China and reconstruct the vitality of streets from the perspective of the traffic users. Based on the “people-oriented” design concept of street traffic, this study took street sections and intersections as the main research object, proposed an overall layout of traffic, space, and facilities. A complete set of humanized and green traffic design methods was constructed to enhance the street vitality. First, through the analysis of the concept of road and street, the traffic connotations of the vital street was determined, the characteristics of the vital street was investigated, and the constituent elements of the vital street was summarized. Then, with a focus on people’s needs, the vital street traffic design methods were mainly divided into two parts: vital street section traffic design and vital street intersection design. Finally, Zhongshan Avenue in Wuhan City was chosen for empirical analysis. Through a field questionnaire survey, the traffic characteristics and traffic demands of residents on Zhongshan Avenue were analyzed, and the traffic design of Zhongshan Avenue was carried out in combination with the traffic design method proposed in this study. The results showed that people’s satisfaction with the renovated Zhongshan Avenue reached 90%. Buses, subways, bicycles, and walkways have become the four major green transportation modes for people to arrive at and leave Zhongshan Avenue, and the renovated Zhongshan Avenue has become a vibrant living street.
