An intelligent emergency service( IES) system is designed for indoor environments based on a wireless sensor and actuator network( WSAN) composed of a gateway, sensor nodes, and a multi-robot system( MRS). If the MRS receives accident alarm information, the group of robots will navigate to the accident sites and provide corresponding emergency services.According to the characteristics of the MRS, a distributed consensus formation protocol is designed, which can assure that the multiple robots arrive at the accident site in a specified formation. The prototype emergency service system was designed and implemented, and some relevant simulations and experiments were carried out. The results showthat the MRS can successfully provide emergency lighting and failure node replacement services when accidents happen. The effectiveness of the algorithm and the feasibility of the system are verified. 展开更多

The proliferation of streaming service system in various application areas gains increasing importance and also poses more challenges in the research of streaming service system. In this paper, we propose a novel dynamic model composed of a set of differential equations to describe the evolution of streaming service systems. And in the model, we focus on how the policies for admission control and peer selection influence on the system. We first introduce a flexible abstraction of streaming service systems. The abstraction is generally enough to capture the essences of streaming service systems with different structures, physical characteristics,software protocols and client behaviors. Then, by analyzing the state which is defined as the number of requests, a novel dynamic model is developed in microscopic scale to characterize the behaviors of streaming service systems. The model proposed in this paper demonstrates the interactions between clients and servers and also between different servers. The interactions are primarily influenced by the admission control policy and peer selection policy. Finally, some experiments are designed to verify the validation and reasonability of the model. 展开更多

Objective Aging process in China has brought more and more challenges to traditional home-based care for the aged and more attentions to the mode of institution-oriented elderly care.This work,by analyzing the problems and defects of institution engaging in elderly care based on the human factors engineering theory,discusses the people-centered institution-oriented elderly care service system,in terms of the problems that the pattern of institution-oriented elderly care focuses more on the facilities and environment construction than the principal role of people in the elderly care service system.Methods Sampled the institutions engaging in elderly care in Hefei City,Anhui Province,P.R.China(a medium-sized city in China);surveyed 45 institutions engaging in elderly care and 828 registered elders in Hefei City by hierarchical and systematic sampling method.Results(1)institutions engaging in elderly care shared the occupancy rate of 49.6%and low total service efficiency;(2)institutions engaging in elderly care offered 100%life-oriented service items,but only 6.1%personalized service items provided;(3)100%simple housing facilities in elderly care institutions,but extremely less personalized service facility(3.2%),with poorer quality and less satisfaction;(4)insufficient professional service staff could be available;48.1%institutions have 5 or less professional service staffs.Conclusion A countermeasure to improve the elderly care service system was raised here by aiming at improving the institution-oriented elderly care service:(1)to transfer service toward the people-oriented concept,formulating preferential policy for endowment insurance;(2)to pay attention to personalized design of service facility,offer personalized and featured service items,and improve service management level;(3)to build professional team for elderly care. 展开更多

In order to fully realize semantic interoperability among distributed and heterogeneous applications on the web, a set of effective interoperability mechanisms is presented. This mechanism adopts service interactive interfaces (SII) and service aggregative interfaces (SAI) modeled with abstract state machine (ASM) to abstractly describe the behavior of the invoked web service instances, which makes business processing accurately specify tasks and effectively solves the problems of communication and collaboration between service providers and service requesters. The mechanism also uses appropriate mediators to solve the problems of information and coinmunication incompatibility during the course of service interaction, which is convenient for service interoperability, sharing and integration. The mechanism' s working principle and interoperability implementation are illustrated by a use case in detail. 展开更多

Parallel kinematics machine (PKM) is advantageous over the serial machine tools in processing the complex-surface products. A manufacturing service system for PKM is developed to provide the services of the complex-surface machining for potential geographically-dispersed manufacturing enterprises. In order to easily in- tegrate the external system, Web services are used to encapsulate post-processing functions of PKM legacy sys- tems, including compilation, workspace calculation, interfere calibration, and kinematics transformation. A ser- vice-oriented architecture(SOA) is proposed for the cooperative work between the PKM system and its client. The workflow and the function module of this manufacturing service system are presented. An example shows that as a result of SOA and loose coupling, such a Web service-based manufacturing service system is easier to in- tegrate and interoperate with its client. Meanwhile, the system decreases the manufacturing cost and improves the efficiency than its former kind of distributed system. 展开更多

With the development of cloud-based data centers and multimedia technologies, cloud-based multimedia service systems have been paid more and more attention. Audio highlights detection plays an important role in the cloud-based multimedia service system. In this paper, we proposed a novel highlight detection method to extract the audio highlight effects for the cloud-based multimedia service system using the unsupervised approach. In the proposed method, we first extract the audio features for each audio document. Then the spectral clustering scheme was used to decompose the audio document into several audio effects. Then, we introduce the TF-IDF method to label the highlight effect. We design some experiments to evaluate the performance of the proposed method, and the experimental results show that our method can achieve satisfying results. 展开更多

With the gradual intensification of aging in China,the issue of elderly care has become the primary issue that needs to be urgently solved in society.The construction of a reasonable and scientific integrated medical and care service system can not only efficiently allocate medical resources and services,but also better meet the needs of the elderly.Due to the involvement of multiple disciplines such as architecture,sociology,psychology,and behavioral science in the construction of the system,as well as the restriction of various objective factors such as medical capacity,spatial scale,and operating costs,the government and elderly care institutions have always been unable to find the best solution for how to scientifically and reasonably construct an integrated medical and care service system.This paper is based on Anshan City,Liaoning Province,which has prominent aging issues and distinct characteristics of the elderly population.Through extensive field research in elderly care institutions,and face-to-face communication with personnel from relevant government departments such as the Municipal Commission on Aging,the Civil Affairs Bureau,the Health Commission,the Medical Insurance Bureau,and the Human Resources and Social Security Bureau,it truly understands the problems that arise in the construction of the urban integrated medical and care service system.From three aspects:urban situation,institutional situation and the needs of the elderly,it is proposed to establish a clear departmental linkage mechanism with clear rights and responsibilities,a policy guarantee mechanism tailored to local conditions,a multi-measure operation mechanism,a technology first intelligent response mechanism,a warm and efficient service mechanism for the people,an overall layout mechanism,an evaluation and supervision mechanism for full process control,and a talent supply mechanism of external introduction and internal training.It aims to provide reference for the construction of an integrated medical and care service system in similar cities. 展开更多

With the deepening of China's aging, China's social pension problem more obvious each day, and gradually become the focus of attention of the whole society. On the one hand, China entered the aging society, old-age needs to grow exponentially. The sixth national census shows that in our country, the population aged 60 and 13.26% of the total population over the total number of 179 million, 65 years and older the proportion of 8.87% of the total population, the absolute number of nearly 120 million. Hundreds of millions of older age groups will produce a growing demand for care services, which is the original old-age service system and the whole economic and social development is a huge pressure. On the other hand, with the economic and social transformation, the traditional model of family pension has been unable to adapt to the profound changes in modem employment, family structure, the concept of retirement, since most parts of China, "old before getting ricE" the situation, how to solve the elderly the pension problem is related to the overall situation of China's economic and social development, related to the overall situation of building a harmonious society in China. Under current national conditions, the emphasis on the development of a single individual body to meet the growing demand for pension service is not realistic, we must mobilize the enthusiasm of all aspects of the element, multi-service integration of resources subject to their commitment to a different responsibilities and tasks provide a full range of care services according to different types, different levels of the actual needs of the older age groups. On the aging problem is that the whole community to face, you need to multi-government body, families, communities, institutions combine effectively starting from the actual needs of the elderly population, according to the financial assistance, life care, spiritual consolation three set the specific needs of services, through a government-led, home-based care services, community care services for the core and supplementary services for institutions focused on pension and other means to provide a full range of pension services. 展开更多

The construction of public toilets is of great significance to urban development, and plays an important role in people's daily life, which can help people avoid the embarrassment of going to the toilet but having nowhere to go. Therefore, we must pay attention to the construction of urban public toilets. Before building public toilets, we must give full consideration to the surrounding regional layout and traffic environment, make a reasonable plan for the location of public toilets, avoid the phenomenon that public toilets are too remote and "nobody cares". It is necessary to proceed from the local actual situation and carry out the transformation and construction according to local conditions. When building public toilets, we must put social and environmental benefits at the forefront and rationally build public toilets, so that China's urban planning and construction work can be upgraded to a higher level. 展开更多
