Nowadays, in order to reach minimum production cost in machining operations, various optimization methods have been proposed. Since turning operation has different parameters affecting the workpiece quality, it was selected as a complicated manufacturing method in this paper. To reach sufficient quality, all influencing parameters such as cutting speed, federate, depth of cut and tool rake angl...

SKD 11 tool steel is among the most popular metals in mold industries for making different kinds of cold work molds and dies with high accuracy and long service life. The demand for higher quality, lower manufacturing costs, particularly the environmentally friendly characteristics, have provided the stimuli for manufacturers and researchers to find alternative solutions. An excellent media is ...

Many interesting social studies can be done by asking people about what they think, feel or experience at the moment when certain events occur in their daily lives. These studies can be conducted based on the event-contingent protocol of the Experience Sampling Method. We have implemented this protocol in Crowdpinion – our software tool consisting of a web panel where the researchers can set up...

Workflow mining aims to find graph-based process models based on activities, emails, and various event logs recorded in computer systems. Current workflow mining techniques mainly deal with well-structured and -symbolized event logs. In most real applications where workflow management software tools are not installed, these structured and symbolized logs are not available. Instead, the artifact...

Making variability explicit in variable artifacts throughout the product lifecycle is difficult for variant modelers due to the different notations used to express variability. The tool integrations of the variant-management tool pure::variants address this problem, by providing a consistent method for denoting variability in frequentlyused development tools. However, differing technical extens...

BACKGROUND African countries are working to achieve rapid reductions in maternal and child mortality and meet their targets for the Millennium Development Goals (MDGs). Partners in the Catalytic Initiative to Save One Million Lives (CI) are assisting them by providing funding and technical assistance to increase and accelerate coverage for proven interventions. Here we describe how the Lives Sa...

Background: Quality of life has been used as an important tool to understand illnesses impact in recent decades. Idiopathic thrombocytopenic purpura is a chronic disease which affects the individuals’ quality of life. The present study was conducted to compare the quality of life among idiopathic thrombocytopenic purpura patients’ with healthy people. Patients and Methods: This was a descri...
