In aluminum extrusion, a work-piece (billet) is pressed through a die with an opening that closely resembles the desired shape of a profile. By this process, long profiles with an enormous variety of cross-sections can be produced to serve different markets such as building, construction and transport industry. When the shape of a profile does not conform to the specifications defined by the cu...

BACKGROUND Advanced cancer can erode patients' wellbeing. Narrative interventions have improved patients' wellbeing, but might not be feasible for widespread implementation. OBJECTIVES (1) Test the effects of miLivingStory, a telephone-based life review and illness narrative intervention with online resources and social networking, on community-dwelling advanced cancer patients' wellbeing. (2...

Plastics extrusion is a manufacturing process suitable for continuous profiles such as floor skirtings, window frames, and pipes. In industrial applications, extrusion is a large-scale process, financially attractive only for mass products. This is due to the time consuming and costly regulation of the extrusion process and especially, the design of an extrusion die which relies on running-in e...

The aim of this study was to evaluate the compaction property of several pharmaceutical materials by measuring the die wall pressure. The profile of die wall force during tabletting process was measured with the compaction process analyzer (TabAll). Several compaction parameters such as maximum die wall pressure (MDP), residual die wall pressure (RDP) and pressure transmission ratio (PTR) from ...

Profile im Internet haben in der heutigen Zeit einen wichtigen Stellenwert eingenommen, um eine Identität online zu repräsentieren und erfreuen sich nicht zuletzt deswegen immer größerer Beliebtheit die allgemeine Beteiligung an sozialen Netzwerken hat in den letzten Jahren drastisch zugenommen. Dies führt unter anderem dazu, dass auch soziale Netzwerke und deren Profile zur Zielscheibe von Int...

die less explosive forming of circular plates is one of the most useful methods in the industries especially chemical applications. manufacturing of large vessel's head, multilayer rings and some parts of heat exchangers are the example of applying this method. many theoretical and experimental researches about examining the explosive forming of simple and single layer plate have been done...

New trends and demands of the automotive industry have dramatically influenced the requirements and processes of tool and die manufacturing over the last years and have led to new, serious and often incoherent challenges for the tool and die makers which have to rethink and redefine their concepts for manufacturing, machinery and production management. To assist in establishing advanced process...

Chemical mechanical polishing (CMP) is widely used for pla-narization of advanced interconnect and shallow trench isolation structures in integrated circuit manufacture. Of particular concern is within-die variation in the interlevel dielectric or oxide thickness remaining after polish, due to pattern density variations across the die. 1 Recent modeling of CMP has shown that a " planarization l...

In diesem Beitrag diskutieren wir die Idee, Konzepte aus den Bereichen der CommunityUnterstützung und ubiquitären Benutzungsschnittstellen auf die Förderung der Fähigkeit zu diskontinuierlicher Innovation in Unternehmen anzuwenden. Unser Fokus liegt dabei auf der frühen Phase des Innovationsprozesses – der Ideengenerierung und kooperativen Ideenvernetzung. Kernidee des Ansatzes ist es, Awarenes...

Since 2012, the state of California faces an extreme drought, which impacts water supply in many ways. Advanced remote sensing is an important technology to better assess water resources, monitor drought conditions and water supplies, plan for drought response and mitigation, and measure drought impacts. In the present case study latest time series analysis capabilities are used to examine surf...
