در بسیاری از تحلیل های آماری، برخی از داده ها نقش بسزایی در تحلیل ها ایجاد می کنند و شاید باعث اختلال در نتیجه گیری ها شوند از جمله ی این داده ها، نقاط پرت و داده های آلوده می باشند که در کران نفوذپذیری تأثیر گذارند و همچنین برآورد های پایدار از پارامتر های مکان چند متغیره و ترکیبی از آنها در مسایل آماری مورد تردید قرار می گیرند. در این پایان نامه، میانه ی پایای تعمیم یافته چندمتغیره خطی را که ...

In order to ensure the safety of vaccines produced on avian cells, rigorous testing for the absence of avian retroviruses must be performed. Current methods used to detect avian retroviruses often exhibit a high invalid-test/false-positive rate, rely on hard-to-secure reagents, and/or have readouts that are difficult to standardize. Herein, we describe the development and validation of two cons...

INTRODUCTION In 2015, the Australasian Pancreatic Club (APC) published the Australasian guidelines for the management of pancreatic exocrine insufficiency (http://pancreas.org.au/2016/01/pancreatic-exocrine-insufficiency-guidelines). Pancreatic exocrine insufficiency (PEI) occurs when normal digestion cannot be sustained due to insufficient pancreatic digestive enzyme activity. This may be rela...

Patients with acute pulmonary embolism (PE) present on a spectrum of clinical severity subset at risk for significant morbidity and mortality. Individuals without contraindications should be treated systemic anticoagulation therapy; however, advanced therapies including fibrinolysis, catheter-based approaches, surgical embolectomy, mechanical circulatory support may considered in the setting he...

Taking into account, the uncertain time duration for each activity in a pert network, we would need to accept the notion that the critical path of the project could also vary a number of times during its execution. If these variations take place frequently during the project in an unpredictable manner, it could endanger the efficient management of that project, and in addition to lengthening th...

We address a PERT/CPM scheduling problem with AND/OR constraints and examine its relations with extremal problems in grammars and hypergraphs. We demonstrate that two scheduling algorithms developed independently by Adelson-Velsky et al. (2002) and Mohring et al. (2004) have different worst-case complexity and, in a sense, are incomparable.
