Resource Management From Single-domain 5G to End-to-End 6G Network Slicing:A Survey

Network Slicing (NS) is one of the pillars of the fifth/sixth generation (5G/6G) of mobile networks. It provides the means for Mobile Network Operators (MNOs) to leverage physical infrastructure across different technological domains to support different applications. This survey analyzes the progress made on NS resource management across these domains, with a focus on the interdependence between domains and unique issues that arise in cross-domain and End-to-End (E2E) settings. Based on a generic problem formulation, NS resource management functionalities (e.g., resource allocation and orchestration) are examined across domains, revealing their limits when applied separately per domain. The appropriateness of different problem-solving methodologies is critically analyzed, and practical insights are provided, explaining how resource management should be rethought in cross-domain and E2E contexts. Furthermore, the latest advancements are reported through a detailed analysis of the most relevant research projects and experimental testbeds. Finally, the core issues facing NS resource management are dissected, and the most pertinent research directions are identified, providing practical guidelines for new researchers.<br/

An analysis of correlation between organizational justice and job satisfaction

This study was an attempt to explore the relationship between organizational justice, encompassed by three components: (distributive justice, procedural justice and interactional justice) job satisfaction, that is employees’ perceptions of workplace justice. This study, indeed, investigated the relationship among these justice measures in the Iranian environment. The data were collected through the distribution of questionnaires among 229 employees of Furniture Manufacturing Company through a stratified random sampling. The study findings showed that only one significant relationship existed between the age of respondents and their perceptions of organizational justice. The findings also suggested that this was a positive association organizational justice and job satisfaction. Employee job satisfaction depended upon the organizational justice of managers. Nevertheless, in measuring the three dimensions of organizational justice, the current study used survey items asking employees whether something is generally fair or not. Finally, although, this study was conducted in Iran, it was expected that the findings might have the relevance on a broader scale. The results could be very helpful for developing a new model of organizational justice with new implementation techniques by replicating this study in different countries and contexts

The efficiency of life skill training on emotional intelligence in chronic addicted women with a history of spousal abuse

BACKGROUND: Low emotional intelligence (EI) could affect individuals' coping strategies and make them vulnerable to violence and addiction. This study aims to study the effect of life skill training to improve EI in chronic addicted women with a history of spousal abuse.METHODS: The study was semi-experimental with a pre-test, post-test design. Conducted between October 2016 and January 2017, this study included women addicted to cannabis with a history of spousal abuse referring to some addiction intervention clinics in Tehran, Iran. 30 individuals were selected based on the inclusion and exclusion criteria and also cut-off point for EI using the convenience sampling method. They were then assigned to two groups randomly (each group n = 15). In six sessions, the experimental group received life skill training and the control group were in the waiting list. Both groups were evaluated in baseline and after the intervention by Ghahari’s domestic violence questionnaire and Bar-on Emotional Quotient Inventory (EQ-i). Data were analyzed using multivariate analysis of covariance (MANCOVA) in SPSS software.RESULTS: The experimental group had improvements in total score and components of EI including interpersonal EQ (F = 312.30, P &lt; 0.050) and intrapersonal EQ (F = 295.04, P &lt; 0.050).CONCLUSION: Life skill training could improve EI in addicted women with a history of spousal abuse

Co-Simulation Methods for Holistic Vehicle Design: A Comparison

Vehicle development involves the design and integration of subsystems of different domains to meet performance, efficiency, and emissions targets set during the initial developmental stages. Before a physical prototype of a vehicle or vehicle powertrain is tested, engineers build and test virtual prototypes of the design(s) on multiple stages throughout the development cycle. In addition, controllers and physical prototypes of subsystems are tested under simulated signals before a physical prototype of the vehicle is available. Different departments within an automotive company tend to use different modelling and simulation tools specific to the needs of their specific engineering discipline. While this makes sense considering the development of the said system, subsystem, or component, modern holistic vehicle engineering requires the constituent parts to operate in synergy with one-another in order to ensure vehicle-level optimal performance. Due to the above, integrated simulation of the models developed in different environments is necessary. While a large volume of existing co-simulation related publications aimed towards engineering software developers, user-oriented publications on the characteristics of integration methods are very limited. This paper reviews the current trends in model integration methods applied within the automotive industry. The reviewed model integration methods are evaluated and compared with respect to an array of criteria such as required workflow, software requirements, numerical results, and simulation speed by means of setting up and carrying out simulations on a set of different model integration case studies. The results of this evaluation constitute a comparative analysis of the suitability of each integration method for different automotive design applications. This comparison is aimed towards the end-users of simulation tools, who in the process of setting up a holistic high-level vehicle model, may have to select the most suitable among an array of available model integration techniques, given the application and the set of selection criteria

An Online Calculating Model for Leachate Production in Mazandaran’s Waste Landfills; (Case Study: Babol Municipal Waste Landfill)

Leachate production and management is a challenging environmental issue in municipal landfills and depots in Iran. Leachate contains toxic materials, heavy metals, and organic and microbial pollutants on a significant scale. Its uncontrolled entrance into the surface, groundwater, and soils can also substantially inverse impacts on human health and natural habitats. In Mazandaran province, during the last decades, depots and landfilling of municipal and industrial waste have led to environmental degradation in its eco-sensitive natural zones and brought a series of health, social, and security challenges to the region. Due to the region's high precipitation rate and landfills with no cover, these places practically convert into an extensive resource for leachate production. To diminish the environmental impacts, a lot of work has been done in recent years to develop a sort of leakage gathering system and treatment plants in these landfills, based primarily on an overall estimation. In this study, a calculating computer model has been developed for leakage production based on regional climate conditions and the characteristics of municipal waste. This model is different from the HELP model, which is commonly used for sanitary landfills and is specifically developed for the waste depots of the Mazandaran province. In this model, hydrological methods, which are based on the water balance in the landfill sites, were used for the calculation. The developed model was uploaded as an online service for public use. By referring to the internet address provided, the developed model in the landfill part and the leachate section, the amount of produced leachate for the landfill site of Mazandaran province can be calculated. Also, the leachate volume of the Babol Anjilsi landfill has been calculated as a case study. As a result of this study, the lowest and highest amount of the production leachate for hot and dry months of the year (June and July) and for wet and rainy months (October) was about 63.39 and 260.07 cubic meters per day, respectively
