Модель оценки рисков при производстве работ

В статье представлено описание модели оценки профессиональных рисков при производстве работ. С помощью модели можно оценить как отдельные риски по одному событию, так и оценить общий риск для всего рабочего места в целом. Применение модели позволит своевременно управлять и принимать решения, что позволит снизить или избежать риска на производстве

Diffusion-based approach to deploying wireless sensor networks

Due to copyright restrictions, the access to the full text of this article is only available via subscription.An important objective of Wireless Sensor Networks (WSNs) is to reliably sense data about the environment in which they are deployed. Reliability in WSNs has been widely studied in terms of providing reliable routing protocols for message dissemination and reliability of communication from sink to sensors. In this work, we define a reliability metric by the amount of data sensed by the network. In order to satisfy this reliability constraint, we propose a diffusion-based approach for a deployment pattern for the sensor nodes. We show that this deployment pattern achieves sufficient coverage and connectivity and requires lesser number of sensors than popular regular deployment patterns. We further obtain the bounds on establishing connectivity between nodes in the WSN and extend this analysis for heterogeneous WSNs

Open or submerged healing of implants with platform switching: a randomized, controlled clinical trial

The temporal pattern of bone-level alterations in conventionally restored implants is dependent upon healing mode (open or submerged). This study examined the influence of healing on marginal bone levels at implants with a medium-rough surface including the implant collar and a clearance-fit implant-abutment connection restored according to a platform-switching concept
