when a change occurs in a process, one expects to receive a signal from a control chart as quickly as possible. upon the receipt of signal from the control chart a search for identifying the source of disturbance begins. however, searching for assignable cause around the signal time, due to the fact that the disturbance may have manifested itself into the rocess sometimes back, may not always l...

in this research, the framework is presented for unsupervised change detection using multitemporal sar images based on integration clustering and level set methods. spatial correlation between pixels were considered by using contextual information. also as proposed method was used integration of gustafson-kessel clustering techniques (gkc) and level set methods for change detection. using clust...

the work of architecture is believed to depend on the governing thought in the process of architectural designing. this thought can be analyzed, developed, experienced, and interpreted. creativity is the only domineering force in the idea of designing which is in quest for freeing architecture from the routine methods, and also finding the novel systems to answer the questions in architecture. ...

a new dynamic friction model for modeling of elliptical vibration assisted turning (evat) was developed in this research. the periodic change of the friction force direction is known to be one of the most important causes of this phenomenon. in modeling of machining processes (including the evat process), static coulomb friction model was employed by most of the researchers. because of the peri...

there is a general consensus that climate change has impact on the intensity and frequency of rainfall events. however, very little research is available about the changes in short term rainfall extremes. the focus of this paper has been on the change in annual and monthly rainfall extremes in ontario. the results indicate a greater variability (increase and decrease) among stations for shorter...

Successful enterprises are built on change. Increasingly, businesses operate in a rapidly evolving environment where the response to changing markets may of necessity be measured in hours and days instead of months and years. Responsiveness and adaptability will be the hallmarks of business success. BT is strategically placed as both a major potential facilitator of this change, as well as bene...

In order to enhance their performance, many organizations have initiated change projects. However, management is reluctant to initiate them due to their enterprise-wide impact and costs that are higher than those of traditional system development projects. Thus, there is a need to assess the value of the redesigned process of a successfully implemented organizational change projects. The purpos...
