Assessing Metal Use and Scarcity Impacts of Vehicle Gliders

This study assesses the metal composition of two vehicle gliders, configured with different equipment levels and evaluates the risk of short and long-term metal scarcity. Entropy analysis is also used for insights on secondary metal recovery strategies. Fifty-five metals are evaluated, with gold, copper, bismuth, lead, molybdenum, and certain rare-earth metals (REMs) subject to the largest supply risks. Differences in equipment levels significantly impact the short-term supply risk for specific metals. Entertainment and communications equipment contain significant amounts of REMs, whereas mirrors and electrical infrastructure contain considerable shares of gold, silver and copper. Some metals are concentrated in a few components while some are dispersed across thousands, impacting recycling opportunities. The broad metal demand of the gliders underscores the automotive industry's role in supply risks for its own manufacturing needs and other societal domains. This emphasizes the significance of comprehensively evaluating metal requirements beyond powertrains for informed resource management.

Analysis of Multimedia Touch Screen Visual Needs of Pre-School Children in the Digital Era

In the advent of the intelligent digital era, numerous industrial products' operations and functionalities have been replaced by digital multimedia touch screens. This shift signifies the gradual integration of digital intelligence visualization into people's lives, work, and learning. Intelligent touch screen devices have replaced mechanically complex office, learning, and entertainment equipment, entering people's lives. This study initially collected relevant domestic and international equipment and research situations, finding that China holds the highest proportion in this category of products and research direction, with considerable accumulated experience. Considering this phenomenon and existing related research, this study focused on pre-school children as the research subjects, investigating the tactile visual and reminder aspects of children's digitized multimedia intelligent touch screen devices. The study revealed that the ownership and usage of such products are significantly influenced by the children's age and their family-related circumstances. Although the elements during usage show minimal differences, combining relevant data highlights pre-school children's visual and interactive requirements during usage. This research conducted surveys and analysis on 102 pre-school children's parents in relatively developed and open areas in China, regarding pre-school children's multimedia touch screen needs and usage, analyzing and discussing related factors, relationships, and patterns of these needs. It has collected and organized preliminary data accurately and in-depth, laying a solid foundation for subsequent related research.

Dadung Feast Rite As A Cultural Expression in Legok Herang Village, Kuningan district

This research aims to examine the tradition of the Dadung Party in Legokherang village, Kuningan Regency, West Java. A tradition that expresses gratitude to God for the harvest and the entity maintaining the relationship between living creatures and nature. The research method used is qualitative with a dance anthropology approach which is elaborated with choreographic concepts. This research shows that the Dadung Party is an integral part of community life and has been passed down from generation to generation. It also has connections to the Islamic beliefs propagated by the Wali Songo. This ritual involves various stages, such as worship, Rajah Pamunah, and entertainment and ritual equipment that must be adhered to by community participants. This tradition is a preserved cultural heritage and functions as a balance to modern culture. The noble philosophical values contained in the dance at the Dadung Party although this dance does not have fixed movements, the emphasis on expression as a manifestation of feelings is very important. Local cultural continuity is a dynamic part of society, and external cultural influences must be adapted to the worldview and local culture.

Sizing of the photovoltaic system for a house located in the Presa la Concepción subdivision in Santiago Cuautlalpan, State of Mexico

To cover the needs of the human being, either electrical or thermal energy is used, which causes greenhouse gases due to the origin of the energy, since most of it is generated by burning fossil fuels. It is necessary to change the source of energy for others that are not polluting, that is, for renewable energies. In a house, energy consumption is in electrical appliances, lighting, air conditioning, entertainment equipment, stove and boyler. In a previous study, strategies were proposed for the passive air conditioning of a house in the Fraccionamiento de Presa la Concepción located in Santiago Cuautlalpan, State of Mexico, considering the bioclimate of the place. In the present study, the photovoltaic system required to cover the energy demand of that house is proposed. The characteristics of the home are briefly described (location, installed load and the bi-monthly consumption reported by CFE), the methodology to be followed for the sizing of the system and its application. A proposal of solar panels, inverter and battery to be used with their respective costs is given.

Heterogeneity Impacts of Farmers’ Participation in Payment for Ecosystem Services Based on the Collective Action Framework

Payments for ecosystem services (PES) are designed to reduce the impact of human activities on eco-sensitive areas. PES programs often adopt economic-incentive and command-control strategies. Increasing the enthusiasm of farmers’ participation is crucial for the sustainability of PES programs and ecosystem restoration. The watershed ecological compensation in Xin’an River Basin is the first horizontal ecological compensation pilot in China. In this study, economic-incentive strategy and command-control strategies in living and farming are implemented simultaneously to improve water quality. Under the collective action framework, we analyze the drivers of farmers’ participation in three concurrent strategies using hierarchical linear models (HLM). The results show: (1) Overall, 81.79%, 76.26%, and 79.11% of farmers are willing to participate in economic-incentive strategy, command-control strategy in living, and command-control strategy in farming, respectively, while 18.21%, 23.74%, and 20.89% are from the village level. (2) Among statistically significant (p < 0.01) factors at the farmer level, social trust (β = 0.305), and social participation (β = 0.134) have positive effects on the economic-incentive strategy; the number of communication and entertainment equipment has a positive effect on the willingness to participate in command-control strategy in living (β = 0.287) and command-control strategy in farming (β = 0.336). (3) At the village level, village characteristics have a direct impact on the farmers’ willingness to participate in strategies. Village woodland area is positively correlated with strategies participation. In addition, village characteristics play a moderating role by influencing farmers’ sustainable livelihood capital. We conclude that different concurrent strategies and collective actions need to be considered in the design of PES programs, particularly in ecologically sensitive areas, which can enrich the theory of collective action and the connotation of PES.

Motion Characteristics Analysis of a Novel Spherical Two-degree-of-freedom Parallel Mechanism

Current research on spherical parallel mechanisms (SPMs) mainly focus on surgical robots, exoskeleton robots, entertainment equipment, and other fields. However, compared with the SPM, the structure types and research contents of the SPM are not abundant enough. In this paper, a novel two-degree-of-freedom (2DOF) SPM with symmetrical structure is proposed and analyzed. First, the models of forward kinematics and inverse kinematics are established based on D-H parameters, and the Jacobian matrix of the mechanism is obtained and verified. Second, the workspace of the mechanism is obtained according to inverse kinematics and link interference conditions. Next, rotational characteristics analysis shows that the end effector can achieve continuous rotation about an axis located in the mid-plane and passing through the rotation center of the mechanism. Moreover, the rotational characteristics of the mechanism are proved, and motion planning is carried out. A numerical example is given to verify the kinematics analysis and motion planning. Finally, some variant mechanisms can be synthesized. This work lays the foundation for the motion control and practical application of this 2DOF SPM.

Investigating a Streaming Analytics Framework for Data Analytics Applications in the Aircraft Cabin

<div class="section abstract"><div class="htmlview paragraph">Aircraft cabin operations shift towards data-driven processes. Cabin-wide multi-system communication networks are introduced to share required data for corresponding novel data-driven applications. Examples are data-driven predictive maintenance applications to reduce the downtime of systems and increase the period of scheduled maintenance or video analytics usage to detect a strained or unruly atmosphere amongst passengers. These applications require a network to transport the associated data and resources for actual computation. Costs and weight have always been the most important factors deciding if new services are introduced within the aircraft cabin. Thus, re-using hardware with free computation capacity that is already installed in the aircraft cabin can target both aspects, weight and costs. Examples for such hardware resources could be the In-flight Entertainment (IFE) equipment being installed in every seat. By means of distributed computing these resources can be combined in order to solve a computational task. In this paper, the Apache Spark Streaming Framework is investigated as an example for a distributed computing framework with respect to its suitability for being deployed in the aircraft cabin. For this purpose, it is evaluated how Spark scales with resource-constrained computing nodes. As this type of framework is designed for a robust execution of tasks, it can also be used for non-safety, but business-critical applications. In addition, Spark is a well-established commercial off-the-shelf (COTS) software, thus, possible advantages of such software like a reduction of non-recurrent engineering costs and support for developers creating applications for the aircraft cabin are also considered.</div></div>

Wi-Fi Adoption and Security in Hong Kong

The benefit of using WiFi for Internet connection is obvious: cost-effective and powerful. WiFi gives us the flexibility and convenience of not being tied to a fixed location. Nowadays, more and more electronic devices and gadgets, such as mobile phones, cameras, gaming devices, TV and entertainment equipment, are WiFi enabled. WiFi also enables your devices to share files instantly. WiFi broadcasting devices, such as Chromecast, give you extra convenience by allowing you to stream video and audio contents from your mobile phone to your TV using WiFi connection. However, this kind of flexibility and convenience comes with a cost. Sharing files, streaming contents or even accessing the Internet via WiFi means signals are being transmitted and they can be captured by anyone with a computer or mobile phone installed with appropriate software. Therefore, it is important to let WiFi users know their security risks and how to minimize them. Educating WiFi users to reduce the WiFi security risk is one of our on-going missions. Basing on empirically collected data, this paper is report of a comprehensive study on the use of WiFi and WiFi networking and the knowledge of WiFi users of the risks and security issues involved in using WiFi in Hong Kong. Findings of the study highlight the WiFi security knowledge gaps of the users in Hong Kong so that stakeholders can take action to improve Internet security by eliminating the security gaps identified.

A Novel Concept for Intermetallic Anodes: Electrochemistry and Thermodynamic Modeling

Secondary lithium ion cells are now universally accepted as a viable key component for electrical energy storage in portable, entertainment, computing and telecommunication equipment required by todays information-rich, mobile society. Predominantly, the lack of suitable reversible negative electrode materials hinders the generation of new lithium ion batteries with distinctly higher charge densities and cycling stabilities. Until now, a variety of (semi-)metal anodes have been tested, promising unrivalled capacities as well as safety due to more positive potentials against Li/Li+ compared to graphite. Sn-based intermetallic anodes are expected to deliver significant capacity increases (960 mAh/g) compared to graphite (372 mAh/g) although they suffer from large volume changes during lithiation/de-lithiation (L/D) which lead to electrode degradation and poor cycling stability. A significant improvement of cyclability can be achieved by using intermetallic alloys, e.g. Cu-Sn or Sb-Sn as anode materials [2015Nit]. The aim of the current project is to combine key experimental data (thermodynamic properties, phase diagram information, crystallographic data) with electrochemically derived data from prototype cells, an approach which was recently validated by Huggins in “Advanced batteries” [2008Hug]. Consistent thermodynamic descriptions of corresponding material systems are developed using the CALPHAD (Computer Coupling of Phase Diagrams and Thermochemistry) method [2007Luk] which is up to now the most advanced method for thermodynamic modeling and simulation of complex heterogeneous systems. This is also a key component of the new ICME (Integrated Computational Materials Engineering) method [2008Com], in which the use of computational thermodynamics helps bridge materials processing and materials structure to be able to predict materials properties. Our thermodynamic descriptions are critical for the design of new electrode materials with optimally tailored properties and allow the evaluation and even the prediction of internal cell reactions and open circuit voltages (OCV). The preparation of phase-pure Li-Sn and Cu-Li-Sn alloys was done by metallurgical techniques adopting special pre-heat treatments and annealing routines. Subsequent characterization was performed by powder X-ray diffraction (XRD), ICP-OES and BSED imaging. The heat capacity (Cp) of selected phase-pure alloys was determined by differential scanning calorimetry (DSC) using a Tian-Calvet type arrangement. Due to the high reactivity of Li, both the synthesis and heat capacity measurements of the respective compounds required the use of tantalum crucibles as well as the manipulation inside an inert gas (Ar) glove box. The derived heat capacity data are implemented into the thermodynamic dataset which enables the temperature-dependent modeling of Gibbs energies and a reliable prediction of electrochemical data at various battery operation temperatures. To verify our calculations, respective phase-pure alloys were used as active materials in battery test cells. Particularly, galvanostatic coulometry and cycling voltammetry were performed in suitable coin cell arrangements against Li/Li+. To facilitate the production of compact electrode materials, active materials were dispersed in N-Methyl-2-pyrrolidone (NMC) together with carbon black to improve conductivity and Polyvinylidene fluoride (PVDF) was added as a binder. Relevant lithiation steps at constant electrochemical potentials were investigated by ex-situ XRD and BSED imaging. For the first time, already lithiated multicomponent intermetallic alloys were used as anode materials so that in the initial cycling step Li was removed from the active Sn-based material. Corresponding effects on cell performance from this new approach will be discussed in detail. [2015Nit] N. Nitta, F. Wu, J.T. Lee, G. Yushin. Materials Today 18 (2015): 252-264 [2008Hug] R.A.

Global Warming Impact on the Earth

Atomic properties of elements and compounds are prone to change due to fluctuation of surrounding temperature and pressure. General properties of elements and compounds are exhibiting at par with the normal temperature and pressure (NTP). As the cause of global warming, the atomic properties of elements and compounds will not behave normally as in NTP. Their characteristics and applications are subjected to evergreen changing process, since natural temperature and pressure are not remaining constant in case of global warming. Whole life pattern of the living beings will be full of complexity and not guided by any rules in case of global warming. Industries, refineries, excessive electromagnetic wave propagation through air, transport vehicles - road and airways, rapid growth of entertainment equipment like air conditioned (A.C) machine, refrigerator, television, mobile phone, computer etc are the main cause of increasing environment temperature. To solve this emerging problem, Industrialization (Industry should grow with minimum working space effecting least environment pollution) and Naturalization (Maximum portion of the earth must be covered with either agricultural green trees or clean water) have to be provided side by side and at the same time people have to minimize using all type of entertainment equipment, otherwise global warming may cause destruction of the world.

News: This Little Standard Went to Market; This Little Standard Blew Up

From ranges of 3 meters to 30 kilometers, broadband wireless technology is poised on the brink of all but eliminating the cords binding millions of devices and the Internet. However, the high economic stakes inherent in creating and dominating any given niche of the wireless network are also creating challenges for standards bodies, notably the IEEE 802 group, which oversees protocol development for local and metropolitan area networks. Two of the IEEE 802 groups in particular - the 802.15.3a task group, overseeing development of wireless personal area network technology, and the 802.20 working group, overseeing development of mobile broadband wireless access-have been substantially bedeviled in recent months by infighting that has delayed research and product development in their respective sectors. The 802.15.3a group, which was exploring standard for wireless universal serial bus (USB) technology, shut itself down in January 2006, after three years of wrangling over two distinctly different approaches to creating wireless connections between PCs, peripherals, and home entertainment equipment. In June, the IEEE standards board suspended the 802.20 group's activities (pdf), after an internal investigation revealed a lack of transparency, possible `dominance,' and other irregularities in the working group.

Do Homeowners Increase Consumption after the Last Mortgage Payment? An Alternative Test of the Permanent Income Hypothesis

The maturity date of a mortgage loan marks the end of monthly mortgage payments for homeowners. In the period after the last payment, homeowners experience an increase in their disposable income. Our study interprets this event as an anticipated increase in income, and tests whether households smooth consumption over the transition period as predicted by the rational-expectation life-cycle–permanent-income hypothesis. We find households do not alter nondurable-goods consumption in the period following the last mortgage payment. Instead, they increase both financial savings and savings in durable goods such as house furnishings and entertainment equipment in the year of the last mortgage payment.

Audio hush for entertainment equipment and particularly television receivers

A user operated remote controller for quieting of sound volume from a television set or other entertainment equipment. User remotely commands an abrupt lowering of the volume to a HUSH level intermediate between a normal and a muted volume level. A remote control command receiver responds to a uniquely encoded wireless “lower the volume” command signal and the volume is immediately lowered to a HUSH level preset just loud enough to telltale a viewer when a program content change occurs, or to allow a parallel activity such as answering a telephone, without completely losing the gist of the audio program content or denying other persons from quietly listening to the program. Temporarily lowers overbearing volume of a television program during station breaks and commercials, while enabling the user to audibly notice when the principal program resumes. Changing a channel selection on a televisor may automatically initiate the lower-volume HUSH mode.

Recent Developments in the Italian Gaming Legal Framework

The “Financial Law” is a particular legislative act, adopted by means of a specific legislative procedure, according to which every year the Houses (Chamber of Deputies and Senate) approve a set of rules aimed at realizing financial effects starting from the first year successive to the one in which the Financial Law is adopted. The last Financial law for the year 2003 introduced interesting provisions aimed at fighting illicit uses of entertainment equipment and devices and at providing new rules for sports wagering and horse race wagering.1 The law provides that the production, importation, and management of entertainment equipment and devices are subject to prior authorization given by the Minister of Economy (through the State Monopolies). On the basis of the authorizations released, the Minister of Economy must set up and manage a national electronic databank containing all the information about production, distribution, importation, and release of entertainment equipment and devices for legal gaming. It must be noted that this electronic databank must be replaced in December 2003 by a telematic network accessible via the Internet. To obtain the ministerial authorization, the following requirements must be met:

Young People's Participation in Sport and other Leisure Activities in the Former Soviet Union

This paper uses evidence from surveys in 1997 among a total of 900 young people (aged 20–26) in Armenia, Georgia and Ukraine to assess the impact of post-communism on their participation in sport and other leisure activities. Despite the rundown of public facilities and organized youth sport, participation was holding up reasonably well.Young males (and rather fewer females) were creating their own opportunities to play sport in parks and other open spaces. However, the main trends in young people’s leisure were towards home-centredness, which was associated with rising investment in home entertainment equipment, towards spending money on ‘quality’ holidays, and towards making regular visits to the bars and restaurants that private commerce had opened in all three countries.It is argued that participant sport is highly vulnerable to, rather than a likely beneficiary of, the reforms in Eastern Europe and the former Soviet Union, and that this situation is likely to continue into the 21st century.

Consumption Target Values for Electrical Appliances in Switzerland

Target values for the power consumption of electrical equipment have been laid down in Switzerland in collaboration with the industry as a new type of energy policy instrument. As a general rule, 95% of the equipment sold is required to comply with these target values by the set deadlines, otherwise the government is authorised to issue admission restrictions. An evaluation of these measures has indicated that manufacturers and importers displayed a motivated and constructive approach during these negotiations and have set out to meet the consumption values. Although the targeted sales figures for efficient appliances have not yet been reached in any of the equipment categories, it can be stated that a step has certainly been taken in the right direction. In combination with the effects of the “Energy 2000 Label”, the stipulation of consumption target values can already be described as a successful move, especially in the fields of office and electronic entertainment equipment.
