Computation of eigenvalues and eigenvectors of a dense symmetric matrix is one of the most important problems in numerical linear algebra. In applications such as molecular orbital methods and first-principles molecular dynamics, eigensolution of matrices of order more than 10,000 is now needed. One of the approaches to solve such a large problem in practical time is to use symmetric multi-proc...

We have developed two automated detectors that can recognize the sulfate mineral jarosite in unknown visible to near-infrared spectra (350– 2500 nm). The two detectors are optimized for use within the terrestrial and martian atmospheres. The detectors are built from Support Vector Machines trained using a generative model to create linear mixtures of library mineral spectra. Both detectors perf...

EMPIRE is a massively parallel semiempirical (NDDO) molecular-orbital program designed to scale well both on single multi-core nodes (using open MP) and on large clusters (using a hybrid open MP/MPI model). The program design and performance are discussed for single self-consistent-field calculations on up to 76,800 atoms and on both singleand multi-node machines using either Windows 7 or Linux...

blow out fracture is a common disease in oculoplastics clinics. one of indication for surgical intervention is entrapment of inferior rectus muscle in the fractured site. in this article authors represent two cases with this disease who underwent surgery for the entrapment of perimuscular fascia without inferior rectus muscle involvement. the results of treatment in both cases were excellent. t...

introduction: fractures of the orbital floor, which are caused by various mechanisms, result in the herniation of periorbital tissue into the paranasal sinuses and its subsequent complications. early diagnosis using various techniques and reduction of fractures are necessary to preserve ocular function and esthetic. use of an endoscope has been associated with some advantages, including a decre...

purpose: to report a case of enophthalmos secondary to complete globe dislocation into the maxillary sinus due to orbital fracture. patient and findings: an 18-year-old man was referred to labafinejad hospital, one week after a car accident. at initial examination, the globe was not seen within the right orbit. a large floor fracture and globe luxation into the right maxillary sinus were confir...

grave’s disease is a clinical syndrome consisting of hypermetabolism, diffuse thyroid enlargement and exophthalmos. which has ocular complications. due to the high incidence of these complications and the risk of blindness special attention is needed. many therapeutic methods including medical surgical and radiotherapy for ocular complications are suggested. in cases of medical therapy failure,...

this article addresses a multi-stage flowshop scheduling problem with equal number of unrelated parallel machines. the objective is to minimize the makespan for a given set of jobs in the system. this problem class is np-hard in the strong sense, so a hybrid heuristic method for sequencing and then allocating operations of jobs to machines is developed. a number of test problems are randomly ge...
