Distributed architecture for energy management D-structure

Electric power systems are expanding in size and complexity, and the requirement for the energy management system (EMS) is becoming more important. In this computer control system, a single control computer is used mainly as the primary computer and its software is very complicated because of its hugh number of small, quick tasks to obtain high response speed. Therefore, much effort is needed to develop and modify the programs, and the responsiveness of this centralized architecture varies greatly when many faults occur in the power system. This paper describes a new distributed architecture for the EMS. Distributed processors execute the functions cooperatively with periodic access to the common bulletin board database in which information about the power system exist. This architecture facilitates the software development and maintenance, and it also enhances the performance by the parallel processing of the distributed functions.     

Practice characteristics that lead to 21st century learning outcomes

Abstract The key research question for this study was to ask whether or not innovative teaching practices would lead to the development of learning outcomes essential for preparing the younger generation for the challenges of life in the knowledge society of the 21st century, and if so, how are the pedagogical features related to the different learning outcomes. Preliminary analyses of the case study data collected from the SITES M2 Study in Hong Kong reveal that where the development of more significant learning gains were observed, the cases possess characteristics additional to the criteria defined in the Study for selection of innovation. More importantly, it was found that the impact of the pedagogical practices was not determined simply by the aggregation of characteristics of the practices per se , nor on the technologies used, but on whether 'empowerment' permeates the curriculum goal and process. Further, this paper claims that these affective and socio-cognitive learning outcomes are more important as preparation for lifelong learning in the 21st century than 'knowledge management competencies'.

农产品电子商务网站的建设与研究

农产品电子商务是一个借助于网络平台新型的农产品销售模式。用户将自己的各类相关信息按照一定的格式输入到电子商务这个系统中,此系统就会协助完成合同的签订、分类、传递和款项收付等全套业务,为卖方以较高的价格出售农产品,买方以较低的价格购入原材料提供了一条非常好的途径,而且也减少了运输渠道所带来的额外消费。因此,农产品电子商务网站的发展对农业的发展和农民的收入的提高有着极大的意义。     

Exploring the security landscape: NoC-based MPSoC to Cloud-of-Chips

In this paper, we present a detailed and systematic overview of communication security aspects of Multi-Processor Systems-on-Chip (MPSoC) and the emerging potential threats on the novel Cloud-of-Chips (CoC) paradigm. The CoC concept refers to highly scalable and composable systems, assembled not only at system design-time using RTL, like traditional SoC, but also at integrated circuit (IC) packaging time thanks to 3D-IC integration technology. Practical implementation of CoC systems needs to solve the problem of scalable, configurable and secure communication not only between different functional blocks in a single ICs, but also between different ICs in a single package, and between different packages on the same or different PCBs and even between different systems. To boost such extremely flexible communication infrastructure CoC system relies on Software-Defined Network-on-Chip (SDNoC) paradigm that combines design-time configurability of on-chip systems (NoC) and highly configurable communication of macroscopic systems (SDN). This study first explores security threats and existing solutions for traditional MPSoC platforms. Afterwards, we propose SDNoC as an alternative to MPSoC communication security, and we further extend our discussion to CoC systems to identify additional security concerns. Moreover, we present a comparison of SDNoC based approach over existing approaches and discuss its potential advantages.     

Forest harvesting in rural properties: Risks and worsening to the worker’s health under the ergonomics approach

Through an ergonomic approach, this study aimed to evaluate whether workers involved in forest harvesting activities in rural properties are subject to the development of work-related diseases, as well as their consequences. A cross-sectional study with 267 forest workers in rural properties in the Brazilian Central region was used. The following evaluations were performed for each of the activities (felling, delimbing, tracing, manual extraction and manual loading): physical workload evaluation; biomechanical evaluation; risk of repetitive strain injuries/work-related musculoskeletal disorders; environmental noise and vibration factors, where relevant, and thermal overload through the Wetbulb Globe Temperature index. The results showed that in general the physical workload was very high, exceeding the cardiovascular load limits and adding to the need for work reorganization. All activities exposed workers to serious and imminent risks of developing injuries to the spine and lower limbs. Likewise, in general the risk of the appearance of RSI/WMSDs was very high for all activities evaluated. Such results are due to the combination of organizational work factors and factors of the work environment such as exposure to bad weather, uneven terrain, lifting and handling loads above tolerable limits, excessive noise and thermal overload. All of this allows to conclude that ergonomic risks and workers’ health hazards in forest harvesting in rural properties are latent and very worrying, and that these workers are exposed to a form of labor exploitation that invariably leads to physical and emotional exhaustion and therefore to their decreased labor capacity and useful working life.
