A double-layer covered architecture with spinel phase induced by LiPP for Co-free Li-rich cathode with high-rate performance and long lifespan

Co-free Li-rich Mn-based layered oxides are promising candidates for next-generation lithium-ion batteries(LIBs)due to their high specific capacity,high voltage,low cost.However,their commercialization is hindered by limited cycle life and poor rate performance.Herein,an in-situ simple and low-cost strategy with a nanoscale double-layer architecture of lithium polyphosphate(LiPP)and spinel phase covered on top of the bulk layered phase,is developed for Li_(1.2)Mn_(0.6)Ni_(0.2)O_(2)(LMNO)using Li^(+)-conductor LiPP(denoted as LMNO@S-LiPP).With such a double-layer covered architecture,the half-cell of LMNO@S-LiPP delivers an extremely high capacity of 202.5 mAh·g^(−1)at 1 A·g^(−1)and retains 85.3%of the initial capacity after 300 cycles,so far,the best highrate electrochemical performance of all the previously reported LMNOs.The energy density of the full-cell assembled with commercial graphite reaches 620.9 Wh·kg^(−1)(based on total weight of active materials in cathode and anode).Mechanism studies indicate that the superior electrochemical performance of LMNO@S-LiPP is originated from such a nanoscale double-layer covered architecture,which accelerates Li-ion diffusion,restrains oxygen release,inhibits interfacial side reactions,suppresses structural degradation during cycling.Moreover,this strategy is applicable for other high-energy-density cathodes,such as LiNi_(0.8)Co_(0.1)Mn_(0.1)O_(2),Li_(1.2)Ni_(0.13)Co_(0.13)Mn_(0.54)O_(2),LiCoO_(2).Hence,this work presents a simple,cost-effective,scalable strategy for the development of high-performance cathode materials.

Space for Hygiene in Housing Architecture

In this paper, the author focuses on spaces used for personal hygiene--the bathroom. The paper begins with a description of the hygienic movement in the late 19th century. At that time, urinating took place in semi-public spaces outside the dwelling. Today, the WC has moved well into the dwelling, and in many dwellings, the bathroom has developed as the most private space. Thus, the bathroom can be regarded as the last domain of privacy in today＇s housing, and in a number of new dwellings this quality is exploited in new ways. The development of ＂space for hygiene＂ in the 20th century will be studied by analyzing the spatial organization of dwellings.

On the architecture and development life cycle of secure cyber-physical systems

Cyber-physical systems are being confronted with an ever-increasing number of security threats from the complicated interactions and fusions between cyberspace and physical space.Integrating security-related activities into the early phases of the development life cycle is a monolithic and cost-effective solution for the development of security-critical cyber-physical systems.These activities often incorporate security mechanisms from different realms.We present a fine-grained design flow paradigm for security-critical and software-intensive cyber-physical systems.We provide a comprehensive survey on the domain-specific architectures,countermeasure techniques and security standards involved in the development life cycle of security-critical cyber-physical systems,and adapt these elements to the newly designed flow paradigm.Finally,we provide prospectives and future directions for improving the usability and security level of this design flow paradigm.

Software Architecture and Methodology as a Tool for Efficient Software Engineering Process: A Critical Appraisal

The foundation for any software system is its architecture. Software architecture is a view of the system that includes the system’s major components, the behaviour of those components as visible to the rest of the system, and the ways in which the components interact and coordinate to achieve the overall system’s goal. Every efficient software system arises as a result of sound architectural basement. This requires the use of good architecture engineering practices and methods. This paper recognizes software architecture practice as a discipline pervading all phases of software development and also presents an enhanced model for software engineering process which provides an avenue for speedy, efficient and timely delivery of software products to their intended users. The integration of software architecture into the phases of software development process in a generic software life cycle is also contained in this research report. This is to enable software engineers and system analysts to use effective software architecture practices and to employ appropriate methodology during the software engineering process.

Enterprise Architecture Ontology for Supply ChainMaintenance and Restoration of the Sikorsky’s UH-60 Helicopter

Ontologies have emerged as an important tool in the Enterprise architecture discipline to provide the theoretical foundations for designing and representing the enterprise as a whole or a specific area or domain, in a scientific fashion. This paper examines the domain of maintenance, repair, and overhaul (MRO) of the Sikorsky UH-60 helicopter involving multiple enterprises, and represents it through an ontology using the OWL Language and Protégé tool. The resulting ontology gives a formal and unambiguous model/representation of the MRO domain that can be used by multiple parties to arrive at a common shared conceptualization of the MRO domain. The ontology is designed to be conformant to ISO 13030 or the Product Life Cycle Support Standard (PLCS) standard, hence representing the state of being as per this standard especially at the interfaces between enterprises while incorporating existing reality to the greatest possible extent within the enterprises. As a result the ontology can be used to design Information Systems (IS) and their interfaces in all enterprises engaged in MRO to alleviate some of the issues present in the MRO area and to support business intelligence efforts.

Phronesis and Dao： Cultivating Ethics and Wisdom in the Process of Making Architecture

Contemporary China, the largest construction site in the world, is the centre of production of architectural ＇vessels＇ that are compacted with technical and scientific knowledge. Nevertheless, traditional wisdom and personal cultivation is often neglected in this process of creating architecture. This paper makes a connection between the Chinese ideogram of 道 （dao = way）, with the Greek term of φρovησιc （phronesis = practical wisdom）, in the context of architecture. We argue that both terms bring forth the importance of ethics and practical wisdom in the making of architecture, as a process of cultivation. This argument is discussed through two case studies： a historical Chinese garden （Sima Guang＇s ＇Garden of Solitary Enjoyment＇）, as a manifestation of Dao, and an educational situation from a contemporary architectural design studio in a school of architecture, as a manifestation of phronesis. Both these diverse examples offer a possibility to see architecture as the creation of ＇vessels for life＇ where ＇vessel＇ and ＇life＇ are inseparable.
