in this paper, absorbing markov chain models are developed to determine the optimum process mean levels for both a single-stage and a serial two-stage production system in which items are inspected for conformity with their specification limits. when the value of the quality characteristic of an item falls below a lower limit, the item is scrapped. if it falls above an upper limit, the item is ...

PURPOSE To look at the presenting features, Enneking stage, size of primary tumour, method of treatment and patient and doctor delays in upper extremity Ewing's sarcoma to observe the effects on local recurrence, metastasis and survival. PATIENTS AND METHODS Nineteen patients with upper extremity Ewing's sarcoma were identified using the Scottish Bone Tumour Registry over the past 40 years. ...

Methods In a 64y o. male a squamous cell lung cancer was diagnosed in his left upper lobe by bronchoscopic brush biopsy cytology. Stage III.A cT2N2MO. He underwent the neoadjuvant treatment: received six cycles of cisplatin etoposid combination. After the restaging (Stage IBycT2NOMO) we performed a pneumonectomy and the mediastinal blockdissection, because of the involvement of the pulmonary ar...

This paper studies a single-stage production system, two-stage production system where specification limits are designed for inspection. When quality characteristics fall below a lower threshold or above an upper threshold, a decision is made to rework or scrap the item. The target is to determine the optimum target for a process based on rework or scrap costs. In contrast to previous studies, ...

To determine the frequency and type of upper gastrointestinal lesions in patients with chronic renal failure (CRF), upper G.I. endoscopy was done in 101 cases. Of the various mucosal lesions, inflammatory changes were seen maximally (40), followed by erosions (16) and ulcers (7). Other changes included atrophic gastro-duodenal folds (17), pale mucosa (11) and moniliasis (6) which was only seen ...

This paper deals with two-stage and multi-stage stochastic programs in which the right-hand sides of the constraints are Gaussian random variables. Such problems are of interest since the use of Gaussian estimators of random variables is widespread. We introduce algorithms to nd upper bounds on the optimal value of two-stage and multi-stage stochastic (minimization) programs with Gaussian right...
