This paper considers the operation of component placement equipment for the assembly of printed circuit boards (PCBs) in a medium volume, medium variety manufacturing environment. It focuses on the setup management and operational planning issues associated with productive use of these expensive resources. The concept of replanning is introduced to adapt to(More)
This paper describes an integrated planning, scheduling and control architecture for robotics and advanced life support systems. The distinctive characteristics of controlled ecologies and the requirements for planning , scheduling and control architectures are presented. Next, the main components of the proposed architecture are described, and the(More)
Clavicle fractures represent 5% of all skeletal injuries, and the distal third of the clavicle is involved in approximately 10%-15% of all these fractures. The incidence of delayed union or non-union in Neer type II fractures of the distal third of the clavicle is high. The ideal treatment for Neer type II fractures of the distal third of the clavicle is(More)
The specificity and affinity of eight lectins (concanavalin A, L. culinaris, P. sativum, phytohemagglutinin P, D. biflorus, soybean agglutinin, T. purpureus, and T. vulgaris) to B, T, T gamma, and T mu lymphocytes from the blood of normal subjects were determined. Lectins attached to latex particles were used to evaluate the binding of each lectin to(More)
A clinical study in a group of patients with digestive cancers was done with a radioimmunoassay technique employing a carcinoembryonic antigen (CEA) fraction. Among 45 patients with colorectal carcinomas, 51% showed CEA levels in the pathologic range before therapy, those with metastatic disease from well differentiated adenocarcinomas showed the higher(More)
Results obtained in three patients with juvenile ischemic stroke and criteria of primary antiphospholipid syndrome is reported. These patients are selected out from a series of 12 patients with 18-mounts follow-up. Lupic anticoagulant and anticardiolipin antibodies were found in two of three patients and one patient show anticardiolipin antibodies with(More)
