This paper proposes a power-based networkconstrained unit commitment (UC) model as an alternative to the traditional deterministic UCs to deal with wind generation uncertainty. The formulation draws a clear distinction between power-capacity and ramp-capability reserves to deal with wind production uncertainty. These power and ramp requirements can be obtained from wind forecast information. Th...
This paper presents a System Dynamics (SD) model of an assembly system in ramp-up with special focus on inspections. The time in-between product development and stable series production is characterized by dynamically changing conditions referring to the product, processes and the assembly system’s organization. Thus, SD serves as an excellent method to model the system’s behavior within the ra...
Meniscal ramp lesions are more frequently associated with anterior cruciate ligament (ACL) injuries than previously recognized. Some authors suggest that this entity results from disruption of the meniscotibial ligaments of the posterior horn of the medial meniscus, whereas others support the idea that it is created by a tear of the peripheral attachment of the posterior horn of the medial meni...
The RAMP herpes simplex virus (HSV) culture confirmation test was compared with immunofluorescence (IF) staining with a specific HSV monoclonal antibody reagent for the detection of HSV in centrifugation culture. The RAMP test detected 47 of 57 IF-positive specimens (sensitivity, 88.6%) and agreed with 217 of 220 IF-negative specimens (specificity, 98.6%). The RAMP test can be performed in less...
This paper introduces dual and primal-dual RAMP algorithms for the solution of the capacitated minimum spanning tree problem (CMST). A surrogate constraint relaxation incorporating cutting planes is proposed to explore the dual solution space. In the dual RAMP approach, primal-feasible solutions are obtained by simple tabu searches that project dual solutions onto primal feasible space. A prima...
Mining frequent itemset using bit-vector representation approach is very efficient for small dense datasets, but highly inefficient for sparse datasets due to lack of any efficient bit-vector projection technique. In this paper we present a novel efficient bit-vector projection technique, for sparse and dense datasets. We also present a new frequent itemset mining algorithm Ramp (Real Algorithm...
Abstract Introduction: Construction projects are one of the most important sectors of the economy of the country, which has a high capacity for job creation. Construction projects are part of a huge and strategic set of civil engineering projects that unfortunately have a large share of work-related accidents due to lack of attention to safety. One of the most important issues that can contrib...
Objective: The Asmari Formation is characterised by alternation thick carbonate and marl sequence of the Oligocene- Miocene in the Zagros Basin, southwest of Iran that were deposited on the shelf of Eastern Paratethys. Methods: This formation is exposed at Tang-e-Khoshk in the Fars subcoastal zone with a thickness of 286 m comprising alternation of medium and thick to massive bedded carbonates,...
