Digital City——An Open Complex Giant System

Dai Ruwei

Strategic Study of CAE 2005, Volume 7, Issue 8,   Pages 18-21

Abstract:

Recently, many people pay attention to design and construct various kinds of systems for digital city by means of automatic control, information and network technology as well as artificial intelligence in domestic cities and areas.

In this article, from system science point view, that a digital city is an Open Complex Giant System (OCGS) by the author is proposed. And the “ metasynthesis from qualitative opinion to quantitative understanding” which is the methodology of OCGS could be applied for dealing with digital city.

Heterogeneous length-of-stay modeling of post-acute care residents in the nursing home with competing

Frontiers of Engineering Management   Pages 577-591 doi: 10.1007/s42524-022-0203-7

Abstract: Post-acute care (PAC) residents in nursing homes (NHs) are recently hospitalized patients with medically complex diagnoses, ranging from severe orthopedic injuries to cardiovascular diseases. A major role of NHs is to maximize restoration of PAC residents during their NH stays with desirable discharge outcomes, such as higher community discharge likelihood and lower re/hospitalization risk. Accurate prediction of the PAC residents’ length-of-stay (LOS) with multiple discharge dispositions (e.g., community discharge and re/hospitalization) will allow NH management groups to stratify NH residents based on their individualized risk in realizing personalized and resident-centered NH care delivery. Due to the highly heterogeneous health conditions of PAC residents and their multiple types of correlated discharge dispositions, developing an accurate prediction model becomes challenging. Existing predictive analytics methods, such as distribution-/regression-based methods and machine learning methods, either fail to incorporate varied individual characteristics comprehensively or ignore multiple discharge dispositions. In this work, a data-driven predictive analytics approach is considered to jointly predict the individualized re/hospitalization risk and community discharge likelihood over time in the presence of varied residents’ characteristics. A sampling algorithm is further developed to generate accurate predictive samples for a heterogeneous population of PAC residents in an NH and facilitate facility-level performance evaluation. A real case study using large-scale NH data is provided to demonstrate the superior prediction performance of the proposed work at individual and facility levels through comprehensive comparison with a large number of existing prediction methods as benchmarks. The developed analytics tools will allow NH management groups to identify the most at-risk residents by providing them with more proactive and focused care to improve resident outcomes.

State identification of home appliance with transient features in residential buildings

Frontiers in Energy 2022, Volume 16, Issue 1,   Pages 130-143 doi: 10.1007/s11708-022-0822-z

Abstract: Nonintrusive load monitoring (NILM) is crucial for extracting patterns of electricity consumption of household appliance that can guide users’ behavior in using electricity while their privacy is respected. This study proposes an online method based on the transient behavior of individual appliances as well as system steady-state characteristics to estimate the operating states of the appliances. It determines the number of states for each appliance using the density-based spatial clustering of applications with noise (DBSCAN) method and models the transition relationship among different states. The states of the working appliances are identified from aggregated power signals using the Kalman filtering method in the factorial hidden Markov model (FHMM). Thereafter, the identified states are confirmed by the verification of system states, which are the combination of the working states of individual appliances. The verification step involves comparing the total measured power consumption with the total estimated power consumption. The use of transient features can achieve fast state inference and it is suitable for online load disaggregation. The proposed method was tested on a high-resolution data set such as Labeled hIgh-Frequency daTaset for Electricity Disaggregation (LIFTED) and it outperformed other related methods in the literature.

Summary and Analysis on the Ecological Civilization Experiences Domestic and Abroad

Yue Bo,Wu Xiaohui,Huang Qifei,Zhang Linbo

Strategic Study of CAE 2015, Volume 17, Issue 8,   Pages 151-158

Abstract:

Since the 1960s, facing to a serious threat of environmental pollution, ecological destruction, survival crisis, the Western countries has carried out a long-lasting work, such as the legal system establishment for ecological protection, environmental and economic policy setting up, the low-carbon green circular economy mode founding, ecological protection awareness training and industrial structure upgrading, etc., which have achieved remarkable progress. Since the middle and late 20th century, China has focused on the construction and protection of ecological environment. In the 18th National Congress of the Communist Party of China, ecological civilization construction has been brought into the “Five in One” overall plan of socialist construction with Chinese characteristics. Since then, the ecological civilization has risen from the academic level to the government’s policy agenda and national philosophy. In further promoting of ecological civilization construction, the following points should be important, which are to learn the ideological essence from ancient ecology, to comprehensively promote the institutional mechanism reform, to strengthen enforcement of the ecological and environmental protection law, to actively found the complex capital for ecological civilization construction, to vigorously promote industrial structure adjustment and upgrading, and to attach great importance to the people’s ecological civilization quality education.
