Requirements of modern cranes and another heavy-duty material handling systems result in demand for sophisticated crane control and automation systems capable of handling loads fast and reliable connection to the particular information systems. These systems continuously provide up-dated information about containers moves and crane status. The total function is built up of a number of distinct ...

OBJECTIVES To assess the exposure-response relationships between work-related physical and psychosocial factors and lateral epicondylitis, medial epicondylitis, cubital tunnel syndrome and radial tunnel syndrome in occupational populations. METHODS A systematic review of the literature was conducted on the associations between type of work, physical load and psychosocial aspects at work and t...

Automated storage and retrieval systems are primarily used for storing and handling unit loads. The Effective Unit Load Dimensions are used to size the system. They include the actual size of the unit load plus all the clearances between adjacent loads to accommodate access and fire prevention devices. The effective unit load dimensions are measured between the centroids of adjacent unit loads ...

Frequent freezes and crashes on current systems bring tremendously heavy loads to the system administration, directly resulting in an undesirable increase on the total cost of ownership (TCO). Obviously, it is time to broaden the long lasting performance-dominated research focus, which has neglected other aspects of computing such as dependability, availability and stability. Deeming that softw...

In order to enhance efficiency of intrusion detection in the Mobile Ad hoc NETwork (MANET), an intrusion prediction method based on intelligent immune threshold matching algorithm was presented. Using a dynamic load-balancing algorithm, wireless network data packet was distributed to a set of analysis subsystem by the balance subsystem; it could avoid packet loss and false negatives in high-per...

The restaurant and food preparation, cooking and distribution sector includes hotels, restaurants, catering, fast food, ecc. The restaurant and food preparation, cooking and distribution sector form a significant part of the Italian economy; they provide employment for a large number of people, both direct employees as well as part-time and contract staff. In this sector there are many hazards ...

This paper briefly summarizes the work related with mobile robotics developed by IST on the field of remote handling operations to be carried out in the International Thermonuclear Experimental Reactor (ITER) by a transfer casks system. The transport operations of contaminated and heavy loads inside ITER buildings requires optimized trajectories. Approaches of path planning and trajectory optim...

This paper describes and analyzes a novel MAC protocol named distributed-control polling (DCP), which has been designed to bring together the most interesting features of distributed-control MAC protocols (e.g., DQDB) and centralized token-passing MAC protocols (e.g. , FASNET, FDDI, EXPRESS-NET). From the fully distributed MAC protocols, DCP acquires the capability to guarantee both a complete ...

Effects of water stress on fruit fresh and dry weights were investigated in peach trees, Prunus persica (L.) Batsch., with varying crop loads: light, moderate and heavy. In well-watered controls, tree water status was independent of crop load. In trees receiving reduced irrigation, the degree of water stress increased with increasing crop load. Water stress induced fruit fresh weight reductions...
