Threads Shuvendu K. Lahiri, Alexander Malkis, and Shaz Qadeer 1 MSR Redmond 2 University of Freiburg Abstract. Verification of large multithreaded programs is challenging. Automatic approaches cannot overcome the state explosion in the number of threads; semi-automatic methods require expensive human time for finding global inductive invariants. Ideally, automatic methods should not deal with t...

With the improvement of social demand for our daily life, products needed in life are getting higher and higher, requirements mechanical structure functions need to be constantly improved, which leads an increase unequal distance threads. This will further improve processing technology efficiency In following, we talk about method rectangular threads, focusing on basic idea NC threads Programmi...

PURPOSE The purpose of this study was to evaluate the effects of abutment screw length and cyclic loading on the removal torque (RTV) in external hex (EH) and internal hex (IH) implants. MATERIALS AND METHODS Forty screw-retained single crowns were connected to external and internal hex implants. The prepared titanium abutment screws were classified into 8 groups based on the number of thread...

OBJECTIVE Online discussion forums are often used by people with eating disorders. METHOD This study analyses 2,072 threads containing a total of 14,903 postings from an unmoderated German "prorecovery" forum for persons suffering from bulimia nervosa (www.ab-server.de) during the period from October 2004 to May 2006. The threads were inductively analyzed for underlying structural types, and ...

AIM To assess the efficacy of a novel ultrasound-guided procedure for the retrieval of intrauterine contraceptive devices (IUDs) when the threads are not visible at the external cervical os ('lost threads'). METHODS This was a prospective cohort study of consecutive women referred for ultrasound examination because of lost IUD threads. The procedures were performed under local anaesthesia in ...

statement of problem: impacts and accidents are considered as the main fac- tors in losing the teeth, so the analysis and design of the implants that they can be more resistant against impacts is very important. one of the important nu- merical methods having widespread application in various fields of engineering sciences is the finite element method. among its wide applications, the study of ...

(a) Method-level (or unit) testing refers to the internal testing of an individual method in a class. Existing testing techniques for conventional programming languages [10-11] are fully applicable to method-level testing. (b) Methods and attributes make up a class. Class-level (or intra-class) testing refers to the testing of interactions among the components of an individual class. (c) Cooper...
