Bidirectional Selection

In the scenario of mobile fog computing (MFC), communication between vehicles and fog layer, which is called vehicle-to-fog (V2F) communication, needs to use bandwidth resources as much as possible with low delay and high tolerance for errors. In order to adapt to these harsh scenarios, there are important technical challenges concerning the combination of network coding (NC) and multipath transmission to construct high-quality V2F communication for cloud-aware MFC. Most NC schemes exhibit poor reliability in burst errors that often occur in high-speed movement scenarios. These can be improved by using interleaving technology. However, most traditional interleaving schemes for multipath transmission are designed based on round robin (RR) or weighted round robin (WRR), in practice, which can waste a lot of bandwidth resources. In order to solve those problems, this paper proposes a novel multipath transmission scheme for cloud-aware MFC, which is called Bidirectional Selection Scheduling (BSS) scheme. Under the premise of realizing interleaving, since BSS can be used in conjunction with a lot of path scheduling algorithms based on Earliest Delivery Path First (EDPF), it can make better use of bandwidth resources. As a result, BSS has high reliability and bandwidth utilization in harsh scenarios. It can meet the high-quality requirements of cloud-aware MFC for transmission.

Methods Of Control

The article is devoted to the analysis of thermometric methods of control and diagnosis of the state of compression of the stator core of the turbogenerator (TG), which have found the greatest application. It is shown that ensuring effective and high-quality control of powerful electric machines, especially power plant generators, today is an integral part of ensuring the reliability and trouble-free operation of their work. As a result of the analysis, it is shown that ensuring high reliability of operation of the generating equipment is practically impossible without their equipping with modern means of control capable to work in real-time.

High Criterion

Hyland, Lee, and Mills (2015) specified the two most popular scales for mindfulness: the Freiburg Mindfulness Inventory (FMI; 30 items, Buchheld, Grossman, & Walach, 2001; 14 items, Walach, Buchheld, Buttenmüller, Kleinknecht, & Schmidt, 2006) and the Mindfulness Attention and Awareness Scale (MAAS; Brown & Ryan, 2003). However, the popularity of these measures does not necessarily mean that they are of high quality. Especially considering the complex epistemology and ontology of the mindfulness construct, we should apply mindfulness assessments with caution. More specially, according to item development theorists in the industrial and organizational (I-O) area (see Hinkin, 1998; Hinkin & Tracey, 1999; Kerlinger & Lee, 2000; Schriesheim, Powers, Scandura, Gardiner, & Lankau, 1993), scholars must select measures that have (a) a clear operational definition; (b) alignment between definition and measure (content validity); (c) high reliability and (d) high construct validity; and (e) high criterion-related validity. However, it is not clear which of the available mindfulness assessments satisfies these criteria and to what extent. In this commentary, we assess currently used measures based on these criteria and provide directions for future research.

Nitrogen Annealing

The gate insulator process for SiC-MOSFET was examined and high-quality interface was realized by employing the pre-annealing process before high-temperature N2 annealing. The pre-annealing evidently activated the interface to introduce nitrogen, and then field-effect mobility exceeded 50 cm2/Vs. The fabricated sample also demonstrated superior bias temperature instability (BTI) and excellent breakdown electric field of 11.7 MV/cm.

Abstract Shaft parts are important parts used in almost all machines including automobiles. In addition, extremely high reliability is required since a shaft failure is directly linked to a fatal machine trouble. Therefore, a hardening process is usually conducted to improve strength and wear resistance. In this study, we propose a new laser heat treatment method to produce high-quality and high-accuracy shafts with high efficiency, low cost and low environmental impact. We will also develop a technique to derive the appropriate laser irradiation conditions quickly and systematically for shafts with various shapes and dimensions. There are the other hardening techniques including the electric furnace method and the induction method. These methods require post-processing for deformation correction, whereas the proposed method uses a laser to achieve thermal deformation-free hardening, eliminating the need for the post-processing. As a result, an improvement in yield can be expected due to a reduction of the products that cannot be corrected after heat treatment, which had to be waste disposed with conventional methods. By using our method, the entire circumference of the shaft was hardened by using a ring-shaped laser beam and a cylindrical inner mirror. Here, the ring-shaped laser beam was formed by high-speed scanning of a spot shapelaser. In the present paper, the details of this system were introduced and some experimental results were described.

Wrong Site

The public, healthcare commissioners and regulators rightly seek assurances about delivery of reliable, high-quality surgical care. The Department of health's 'never events' framework 1 specifically lists patient misidentification, wrong-site surgery and retained swabs and instruments as unacceptable occurrences. Professional conversations reveal many seemingly inconsequential daily occurrences that have an impact on patient outcome and ongoing management. Unfortunately, many of these incidents are not reported formally by those involved, which limits the opportunity for professionals and organisations to learn from subsequent analysis.
