Introduction. In construction enterprises are hundreds of types and thousands names low-value perishable items (LVPI) non-current tangible assets (LVNTA), which require a more detailed study significant reduction costs from the buyer to production consumption at specific site. For every enterprise, it’s important prevent loss these during their acquisition, transportation, acceptance-handover, ...

In the Manning equation the hydraulic radius can be defined as the cross-section dimension of the shape. In pipe flow the bed shear stress is assumed to be uniformly distributed along the wetted perimeter which cannot be true in open channel flow. Hence, three approximation of the true boundary shear-stress distribution are examined and more practical conveyance depth or resistance radius formu...

MIRZAEE TESHNIZI, HESAMEDDIN. Medium-Voltage DC Power Conversion and Distribution for Efficient Electric Power Delivery in Shipboard and Mobile Mining Application. (Under the direction of Dr. Subhashish Bhattacharya). Medium-Voltage DC (MVDC) distribution and power conversion systems have become more attractive in recent years due to advances in power electronic technology. It can be used in a ...

E366 CMAJ, April 19, 2011, 183(7) © 2011 Canadian Medical Association or its licensors The study by Haegeli and coauthors in CMAJ provides new insight into survival patterns after complete avalanche burial. The authors report survival curves from data for 301 complete avalanche burials in Canada from 1980 to 2005 and compare them with the standard survival curve derived from Swiss data for 946 ...

The Miami Conservancy District built five flood control dams after the catastrophic flood of 1913 in Dayton, Ohio. Lockington Dam was one of these five hydraulic fill structures. The Ohio State Department of Natural Resources (ODNR) issued new regulations in 1981 requiring that design flood for class I dams be considered equal to the Probable Maximum Flood (PMF). Flood routing studies performed...

When people talk, they gesture. Typically, gesture is produced along with speech and forms a fully integrated system with that speech. However, under unusual circumstances, gesture can be produced on its own, without speech. In these instances, gesture must take over the full burden of communication usually shared by the two modalities. What happens to gesture in this very different context? On...

In all networks that provide a service to the consumer, one of the main performance indicators is availability. The consumer, the user of the service, wants to be able to use the service for at least X% of the time. In order to be able to make such guarantees and commit to them in Service Level Agreements, network operators need to know their network availability. In this paper, we discuss how ...

The rutschblock test is one of the most reliable snow stability tests. It is a mini slab avalanche that is tested with the appropriate dynamic load: the skier or snowboarder. The test method and its limitations are reviewed. The application of the rutschblock test as the standard stability test in the observational network of the Swiss Avalanche Warning Service is described. Introduction The ru...

Avalanches are one of the major threats to life in high mountain terrain. Once buried by an avalanche, survival chances dramatically drop from 92% after 15 minutes to only 30% after 35 minutes mostly due to the lack of oxygen. It is therefore extremely important to rescue any victims as fast as possible in order to maximize survival chances. Today’s technology, so called electronic avalanche be...

Growing trends toward increased complexity and prolonged useful lives of engineering systems present challenges for system designers in accounting the impacts post-design activities on performance (e.g., costs, reliability, customer satisfaction, environmental impacts). Examples include manufacturing, condition monitoring, remaining life prediction, operations maintenance, service logistics, as...
