The present work demonstrates the successful application of a simple active vibration control procedure based on structural dynamics. Based on mathematical and structural dynamics’ theories, the appropriate locations of sensor and actuator locations of the smart structure are predicted. Also, the optimum value of actuator force which controls the structural vibrations as quickly as it is possib...

We present the architecture of a workkow system based on active databases. Business processes can be deened in an easy-to-use graphical workkow description language. Process descriptions written in this language are compiled to rules and executed in a system based on an active database. Thus the workkow system can take full advantage of the capabilities of a database system such as reliability,...

OBJECTIVES To determine the prevalence and risk factors for work related musculoskeletal disorders among union carpenters. METHODS A detailed questionnaire on musculoskeletal symptoms and work history was administered to 522 carpenters. The symptom questions assessed if carpenters experienced pain, numbness, or tingling in a particular body region. A subset of this group then received a physi...

Active commuting (AC), the act of walking or biking to work, has notable health benefits though rates of AC remain low among women. This study used a social-ecological framework to examine the factors associated with AC among women. A convenience sample of employed, working women (n = 709) completed an online survey about their mode of travel to work. Individual, interpersonal, institutional, c...

Anthralin and some of its derivatives have implied antipsoriatic effect in clinical and pharmaceutical studies. Anthralin is synthesized by different strategies. In this work we report the synthesis of "OEHA" as a precursor of another biological active compound.

This paper presents a dynamic sensor planning system, capable of planning the locations and settings of vision sensors for use in an environment containing objects moving in known ways. The key component of this research is the computation of the camera position, orientation, and optical settings to be used over a time interval. A new algorithm is presented for viewpoint computation which ensur...

BACKGROUND The American Cancer Society's Active for Life is a worksite wellness program that encourages employees to be physically active. This paper reports the experience of implementing Active for Life in a worksite setting and its longer-term impact on physical activity. CONTEXT The Active for Life intervention was provided to employees at Group Health Cooperative, a nonprofit health care...
