operator's role in industrial control centers takes place in time, which is one of the most important determinants of whether an expected action is going to be successful or not. in certain situations, due to the complex nature of the work, the existing interfaces and already prepared procedures do not meet the dynamic requirements of operator's cognitive demands, making the control tasks unnec...
insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...
this paper presents a control model of the hydroforming and the dual hydroforming process of atube. the theoretical part includes calculations to measure the change in tube thickness through thedeveloped process. the hydroforming and the dual hydroforming processes are simulated in thesolidsimulation software and the static and the dynamic simulations are modeled. theobtained results for the t-...
An Overview of Computer Aided Design/Computer Aided Manufacturing (CAD/CAM) in Restorative Dentistry
Objective: To review the current knowledge of CAD/CAM in dentistry and its development in the mentioned field. Sources: An electronic search was conducted across Ovid Medline, complemented by manual search across individual databases, such as Cochrane, Medline and ISI Web of Science databases and Google Scholar for literature analysis on the mentioned topic. The studies were reviewed thoroughly...
background: antifungal drug resistance and few numbers of available drugs limit therapeutic options against fungal infections. the present study was designed to discover new antifungal drugs. m aterials and methods: this study was carried out in two separate steps, that is, in silico lead identification and in vitro assaying of antifungal potential. a structural data file of a ternary complex...
in iran we already use laminate tubes only in cosmetics industry. laminate tube manufacturers via using the most modern technology of the world, faced with the laminate tube market being saturated in cosmetics industry for packaging the cosmetic creams and toothpaste. but considering the great food market and therefore laminate tube features such as beautiful packaging, ease of use for the fina...
Computer-aided process planning (CAPP) is an essential component in linking computer-aided design (CAD) and computer-aided manufacturing (CAM). Operation sequencing in CAPP is an essential activity. Each sequence of production operations which is produced in a process plan cannot be the best possible sequence every time in a changing production environment. As the complexity of the product incr...
background: the aim of this study was to determine the microtensile bond strength (μtbs) of ceramic and composite computer aided design‑computer aided manufacturing (cad‑cam) blocks bonded to dentin using different adhesive strategies. materials and methods: in this in vitro study, 30 crowns of sound freshly extracted human molars were sectioned horizontally 3 mm above the cementoenamel junctio...
