Cobalt improves nickel hydroxide electrodes for batteries

Positive nickel hydroxide electrodes containing 20 mole percent of cobalt hydroxide are more efficient than when impregnated to the same degree by weight with nickel hydroxide alone. Charge-acceptance and oxygen-evolution tests indicate cobalt electrodes are more efficient than plain positive nickel hydroxide electrodes at all rates of charge

Self-managed Workflows for Cyber-physical Systems

Workflows are a well-established concept for describing business logics and processes in web-based applications and enterprise application integration scenarios on an abstract implementation-agnostic level. Applying Business Process Management (BPM) technologies to increase autonomy and automate sequences of activities in Cyber-physical Systems (CPS) promises various advantages including a higher flexibility and simplified programming, a more efficient resource usage, and an easier integration and orchestration of CPS devices. However, traditional BPM notations and engines have not been designed to be used in the context of CPS, which raises new research questions occurring with the close coupling of the virtual and physical worlds. Among these challenges are the interaction with complex compounds of heterogeneous sensors, actuators, things and humans; the detection and handling of errors in the physical world; and the synchronization of the cyber-physical process execution models. Novel factors related to the interaction with the physical world including real world obstacles, inconsistencies and inaccuracies may jeopardize the successful execution of workflows in CPS and may lead to unanticipated situations. This thesis investigates properties and requirements of CPS relevant for the introduction of BPM technologies into cyber-physical domains. We discuss existing BPM systems and related work regarding the integration of sensors and actuators into workflows, the development of a Workflow Management System (WfMS) for CPS, and the synchronization of the virtual and physical process execution as part of self-* capabilities for WfMSes. Based on the identified research gap, we present concepts and prototypes regarding the development of a CPS WFMS w.r.t. all phases of the BPM lifecycle. First, we introduce a CPS workflow notation that supports the modelling of the interaction of complex sensors, actuators, humans, dynamic services and WfMSes on the business process level. In addition, the effects of the workflow execution can be specified in the form of goals defining success and error criteria for the execution of individual process steps. Along with that, we introduce the notion of Cyber-physical Consistency. Following, we present a system architecture for a corresponding WfMS (PROtEUS) to execute the modelled processes-also in distributed execution settings and with a focus on interactive process management. Subsequently, the integration of a cyber-physical feedback loop to increase resilience of the process execution at runtime is discussed. Within this MAPE-K loop, sensor and context data are related to the effects of the process execution, deviations from expected behaviour are detected, and compensations are planned and executed. The execution of this feedback loop can be scaled depending on the required level of precision and consistency. Our implementation of the MAPE-K loop proves to be a general framework for adding self-* capabilities to WfMSes. The evaluation of our concepts within a smart home case study shows expected behaviour, reasonable execution times, reduced error rates and high coverage of the identified requirements, which makes our CPS~WfMS a suitable system for introducing workflows on top of systems, devices, things and applications of CPS.:1.

"‘Mixed’ Japanese-Filipino identities under Japanese multiculturalism"

The ways in which multiculturalism is debated and practiced forms an important frame for ‘mixed’ ethnic identities to take shape. In this paper, I explore how young migrants of Japanese-Filipino ‘mixed’ parentage make sense of their ethnic identities in Japan. My key findings are that dominant discourses constructing the Japanese nation as a monoracial, monolingual and monoethnic nation leave no space for diversity within the definition of ‘Japanese’, creating the necessity for alternative labels like haafu or ‘mixed roots’. Japanese multiculturalism does not provide alternative narratives of Japaneseness but preserves the myth of Japanese racial homogeneity by recognizing diversity while maintaining ethnic and racial boundaries. Lastly, these categories have not been actively questioned by my respondents. Rather, they show flexibility in adopting these various labels – haafu, ‘mixed roots’, Filipino, Firipin-jin – in different contexts. KEYWORDS: Japanese-Filipino children, mixed-ethnic, identity, multiculturalism, Japa

The Confluence of Faraday's and Kirchoff's Laws in Bioelectrochemical Systems

When external measurements are made of electrochemical systems, including bioelectrochemical, there results an interaction. Such measurements cause electrochemical processes to take place that are significant. This work looks into the nature and significance of the interfacial processes on membrane and membrane phenomena. The conclusion reached is that interfacial processes are important and cannot be overlooked

Improvements of Paediatric Triage at the Emergency Department

__Abstract__ The practice of triage, originated from the French word “trier” which means to sort, was conceived around 1792 by Baron Dominique-Jean Larrey, Surgeon in Chief to Napoleon’s Imperial Gard. In these days, triage was used to identify soldiers whose injuries were readily treatable in order to return them to battlefield at the earliest opportunity. In 1846, the British naval surgeon John Wilson was the first who argued that treatment should be given first to patients who need immediate and potentially successful treatment. During World War I, the introduction of new weapons created an unprecedented number of potentially treatable mass casualties. This led to a wide introduction of the term “triage” and to a new definition of its concept, in which triage was not only aimed at sorting treatable patients from untreatable patients, but also took into account the complexity of treatable patients in order to save as much patients as possible. Nowadays, triage aims to prioritise patients according to their medical presentation in situations with modest scarcity of health care resources. This scarcity of resources is not only present at the military battlefield or in case of mass casualties and disasters, but can also occur at the emergency department (ED) or in the hospital settings with limited numbers of beds such as the intensive care unit. Although all these settings have distinguishing features, each requires the presence of a trained health care worker (“triage nurse”) to assess the patient’s medical needs, and an established system or plan to determine patient’s priority
