The Research on the Characteristics of Chinese Game Virtual Streamers

With the development of the metaverse, many activities have been infiltrated into various virtual interactive experiences. In the widespread live-streaming industry, the virtual anchors who stream behind various animated avatars are favored by a majority of young people. This paper summarizes five characteristics of Chinese game virtual streaming through observations on Bilibili live streaming platform and social media such as Weibo, TikTok and Little Red Book. The author believes that Chinese game virtual streamers have strong role-playing quality, a variety of live games content, humor, versatility and the ability to follow the latest trends. Through these characteristics, they can enrich the live content to attract more audience attention, also strengthen the interaction with the audience and meet the needs of the audience to a greater extent, thus promoting the development of the virtual streaming industry. The analysis of the characteristics of game virtual streamers can make the streamers better improve and strengthen their own advantages and expand the audience group, as well as enable the audience to have a deep understanding of the virtual streamers, which encourages a more appropriate and rational virtual stream watching experience.

How might we simulate a riverside experience through virtual collaboration?

In this paper we explore convergences between personal experiences with water and film-making. Employing a cross-disciplinary collaborative dialogue, Latham and Ward create a virtual stream, that explores the language of each other’s praxis, in architecture and film. McLuhan’s notion that: “The reader is the content of any poem or of the language [s]he employs, and in order to use any of these forms, [s]he must put them on,” (McLuhan 1971, 520) provides a signpost for the immersive experience we seek in our understandings of river, and in our approaches to disciplinary practice.During lockdown in the UK, a displaced, virtual riparian conversation evolved. Through online exchanges of particular ways of seeing and using film as method, new flows in the space between film and architecture, making and experiencing, emerge as a site for experimentation and interrogation. Through remediation and overlay of individual and shared embodied water experience, a conflated flux of differences point towards a new river paradigm.

Design and Implementation of Virtual Stream Management for NAND Flash-Based Storage

NAND flash memory is being widely used as data storage in consumer electronics devices such as tablet computers and smartphones. However, due to the inherent nature of NAND flash memory where in-place update is not supported, NAND flash-based SSDs (Solid-State Drives) suffer from severe performance degradation as they need to move valid data during garbage collection (GC). Recently, multi-streamed SSDs have been proposed to reduce the cost of GC in the SSDs. However, commercial SSDs used in consumer electronics devices support only a small number of streams due to the device’s limitation in hardware resources. This makes it difficult to fully utilize the benefits of the multi-streamed SSDs. In this article, we propose a new concept of <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">virtual streams</i> ( <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">vStreams</i> ) that are independent of the number of available streams within the multi-streamed SSDs. We present the design and implementation of virtual stream management architecture, called vStream-FTL, for efficient stream management in the SSD. Specifically, we present novel mechanisms to monitor the lifetime of each stream with a negligible memory overhead and map one or more vStreams into a physical stream at run time according to the lifetime of vStream. In addition, we implement the enhanced garbage collection scheme, called <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">vStream-aware GC</i> that increases the benefits of multi-streamed SSDs further. Our vStream-FTL allows embedded system developers to manage a sufficient number of streams regardless of the physical streams supported by the device. The evaluation results with smartphone workload show that the proposed vStream-FTL improves throughput by 48% compared to the Legacy-FTL with no stream support.

Virtual stream computing systems with a fuzzy computing environment

The paper reveals the architecture (structure) of virtual stream computing systems with a fuzzy computing environment (closure conditions, constraints, exchanges, small scales and information uncertainty). The system assumes that hardware-software, computing and information-intellectual functions of such systems can actually be implemented and implemented in the form of hardware, software, brainware products for supercomputer technologies of mathematical modelling. Such products allow to obtain more adequate, reliable, meaningful and valuable results in the computational technologies of mathematical modeling. . This is due to the fact that the logic circuits of algorithms and procedures of computational technologies include an information system for referencing coordinates and checking the results of calculations in a fuzzy (diffuse) computing environment based on the principles of locality and specifying the model of the information environment for generating a result.

Flotation plant-wide control strategy evaluated on hybrid pilot plant

In this work, the implementation and use of a metallurgical simulator for a flotation plant, including rougher-cleaner-scavenger, RCS, is presented. The simulator can be fed by the user with input operating and metallurgical variables generated off line or in a hybrid manner. In the last case, the operating variables of all circuits are read from instrumentation installed in the pilot plants and combined with virtual variables, generated by the user, to run the metallurgical simulator in order to predict the characteristics of each virtual stream. The pilot plant is located at the Process Control Laboratory and includes a three pneumatic cells rougher circuit, a flotation column and a two pneumatic cell scavenger circuit. The regrinding and classification stages are simulated by using models based on literature.An expert control system is built in order to find out best operating points, in the sense of metallurgical results, mainly Cu global recovery and specified characteristics of the final concentrate. The expert system administrates the set points of the controllers of the operating variables of the plant (froth depths and air flow rates). The control strategy maximizes the rougher Cu recovery subject to the condition that the produced rougher concentrate can be adequately processed in the cleaner, regrinding, classification and scavenger circuits. To achieve this, the quality of the rougher concentrate (Cu grade over a given value and solid mass flow rate under a given value) is monitored jointly with the degree of saturation of manipulated variables in the rest of the circuits, the quality of the final concentrate and the recovery of the scavenger circuit. The result is to find out how to operate the whole plant to obtain both a final concentrate meeting specifications and the maximum Cu global recovery of the plant. Several examples are discussed.

Coverage-enhancing approach in multimedia directional sensor networks for smart transportation

Smart transportation has a significantly impact on city management and city planning, which has received extensive attentions from academic and industrial communities. Different from omni-directional sensing system, as a directional sensing system, the multimedia-directional sensor network holds the special coverage scheme, which is usually used for smart cities, smart transportation, and harsh environment surveillance, for instance, nuclear-pollution regions where are inhospitable for people. This paper advances Virtual Stream Artificial Fish-swarm based Coverage-Enhancing Algorithm (VSAFCEA) as a coverage-enhancing means in multimedia directional sensor networks. Firstly, a concept of virtual streams, based on traditional artificial fish-swarm algorithm, is proposed. Then, the traditional behaviors of fishes in artificial fish-swarm algorithm are modified and expanded with several new behaviors. Finally, the presented VSAFCEA is adopted for coverage-enhancing issue in the situation of directional sensor networks with rotational direction-adjustable model. With a sequence of steps of artificial fishes in virtual stream, the presented VSAFCEA can figure out the approximation to the highest area coverage rate. Based on comparison of these simulation results (results of presented VSAFCEA and that of other typical coverage-enhancing ways in directional sensor networks), the conclusion can be drawn that VSAFCEA could attain higher area coverage rate of directional sensor networks with fewer iterative computing times.

Heat recovery networks synthesis of large-scale industrial sites: Heat load distribution problem with virtual process subsystems

This paper presents a targeting strategy to design a heat recovery network for an industrial plant by dividing the system into subsystems while considering the heat transfer opportunities between them. The methodology is based on a sequential approach. The heat recovery opportunity between process units and the optimal flow rates of utilities are first identified using a Mixed Integer Linear Programming (MILP) model. The site is then divided into a number of subsystems where the overall interaction is resumed by a pair of virtual hot and cold stream per subsystem which is reconstructed by solving the heat cascade inside each subsystem. The Heat Load Distribution (HLD) problem is then solved between those packed subsystems in a sequential procedure where each time one of the subsystems is unpacked by switching from the virtual stream pair back into the original ones. The main advantages are to minimize the number of connections between process subsystems, to alleviate the computational complexity of the HLD problem and to generate a feasible network which is compatible with the minimum energy consumption objective. The application of the proposed methodology is illustrated through a number of case studies, discussed and compared with the relevant results from the literature.

EFFECTS OF PASSAGE BARRIERS ON DEMOGRAPHICS AND STABILITY PROPERTIES OF A VIRTUAL TROUT POPULATION

ABSTRACTHabitat fragmentation is widely assumed to have negative effects on populations and communities, but some effects of fragmentation are subtle, difficult to measure and not always negative. For stream fish, barriers to upstream passage, such as waterfalls or culverts with perched outlets, are a common cause of fragmentation. We explored the effects of barriers on a virtual stream trout population occupying a network of reaches in the inSTREAM individual‐based trout population model. The model includes daily habitat selection by individual fish, with barriers represented by assuming trout cannot move upstream past a barrier and move downstream over a barrier only if habitat above it offers low potential fitness. In 78‐year simulations of a resident trout population occupying the stream network of a 25‐km2 catchment, we varied barrier density and observed effects on population stability properties and demographics. Increasing barrier density decreased subpopulation persistence in first‐order tributaries but not larger streams. Barriers at tributary mouths reduced the population's resistance to extreme flows, but additional barriers caused no further loss of resistance. Barriers reduced overall abundance and biomass at intermediate and high densities and caused a small but surprising increase in biomass at low density. In comparison with fish in the remainder of the network, fish in isolated first‐order tributaries had higher survival early in life, smaller sizes at age and reproduced as smaller, younger individuals. Fish that passed over barriers contributed relatively little to downstream populations but, had they not moved, would have increased persistence and abundance of the tributaries they moved from. Relationships such as these would be very difficult to elucidate without a model representing individual behaviour. Copyright © 2011 John Wiley &amp; Sons, Ltd.

Further appreciation of a control system for chemical reactions residing in virtual energy flows through the bio-system

The argument has been advanced in previous papers that the radiative field of classical electromagnetics is a special case of envelopment of space itself (termed here ‘non-reap’ or ‘imaginary energy’) by waves of this field according to the formalism of Clark Maxwell (termed here ‘real energy’) and that, in its non-enveloped state, the virtual field is of special significance for the functioning bio-system.This paper summarizes evidence from a preceding paper from the areas of physical chemistry and theoretical physics to validate the presence of just such a radiationless, non-enveloped virtual field of space elements dissipating matter of inanimate and animate types. As discussed, the non-enveloped field is subject to envelopment by magnetic fields and by the heat part of the electromagnetic spectrum. It is reasoned that the envelopment process itself is concerned with a thrust-delivering atomic and molecular movement so familiar in bio-system function.The virtual stream develops from the polyatom and polymer state so that wavelengths of its components are greater than those wavelengths associated with individual atoms or molecules. The division between the two wavelength types is set for purposes of this quasi-mechanical approach to space elements at the heat part of the spectrum. Properties of control and stability over atomic and molecular systems derive from this wavelength advantage.Irrespective of wavelength, the virtual system is operative free of heat and of the magnetic field. In the presence of appropriate threshold values, these enveloping agents then manifest an arrangement of space elements in real energy or radiative terms. Events during these transitions confer important physical properties on all matter but they are more highly developed and the control they exercise more subtle in animate matter.
