iran is a major world producer of walnuts and a hub of walnut exports to other countries. walnut harvesting and cracking is still done manually, which increases price and waste. design and development of an effective harvester and walnut crusher is required to reduce costs and wastage. this study determined the mechanical properties of a test apparatus employing two flat jaws using different tr...

In functional genomics, the high-throughput methods such as microarrays 1) allow analysis of the relationships between genes considering them as elements of a network and 2) lead to biological interpretations thanks to Gene Ontology. But up to now it has not been possible to find relationships between the functions and the connectivity of the genes in coexpression networks. To achieve this aim,...

We examine two factors that might explain the extent of air traffic delays in the United States: network benefits due to hubbing and congestion externalities. Airline hubs enable passengers to cross-connect to many destinations, thus creating network benefits that increase in the number of markets served from the hub. Delays are the equilibrium outcome of a hub airline equating high marginal be...

Standardized methods of power transmission and motion transfer use different elements, such as keys, wedge-shaped shafts, polygonal shafts, and lateral pins to join the hub of driving or driven elements with the shaft, or make use of friction connections (cylindrical tightening connection, conical connection, tightening elements). Nowadays, the key is accepted as a universal joining method most...

We consider the problem of recovering the graph structure of a “hub-networked” Ising model given i.i.d. samples, under high-dimensional settings, where number of nodes p could be potentially larger than the number of samples n. By a “hub-networked” graph, we mean a graph with a few “hub nodes” with very large degrees. State of the art estimators for Ising models have a sample complexity that sc...

This study analyzed the fundamental geometric and kinematic characteristics of the swing hub path of the golf shot for four diverse subjects. In addition, the role of the hub path geometry in transferring the kinetic quantities from the golfer to the club were investigated. The hub path was found to have a complex geometry with significantly changing radii, and a constantly moving center-of-cur...

BACKGROUND Current WHO best infection control practices for injections do not address the use of hub cutters due to insufficient evidence on safety and efficacy. OBJECTIVE To assess the impact of the use of hub cutters on 1) the frequency of needle-stick injuries (NSIs) and other blood exposures among workers and 2) the volume of sharps waste in a mass vaccination campaign setting. METHODS ...

Hub ports play an important role in reducing the number of container routes and saving operating costs liner companies. However, hub failures caused by uncertainties such as natural disasters may cause huge recovery costs. Considering accidental failure probability reallocation feeder ports, a global reliable shipping location problem (RLSHLP) is studied. We use k-means algorithm to divide netw...

This article presents an analysis of Reception, Staging and Onward Movement hub (RSOM-hub) concept to support Canadian Forces (CF) Northern operations and provides insights into the optimal RSOM-hub locations. RSOM-hubs are permanent or temporary staging bases for cross-loading between strategic and tactical lift during military deployment and sustainment operations. Performance measures were d...

Background Telestroke is recognized as a safe and time-efficient way of treating stroke patients. However, admission centers (spokes) are subject to financial charges which can make them reluctant to join the system. We implemented and assessed an economic model supporting our telestroke system, Virtuall, France, which includes one expert center (hub) and six spokes. Methods The model is base...
