The objective of this PhD is to study the seismic behavior of elastic and inelastic structural systems equipped with viscous and viscoelastic dampers and develop design procedures according to Eurocode 8 for steel buildings. Both types of dampers belong to the category of passive supplemental damping devices. These devices can be used either for new building or for retrofitting purposes of existing buildings. Dampers act by dissipating seismic energy and can significantly decrease the response of
To analyze the activity of alkaline phosphatase at different substrate concentrations, a continuous assay was conducted, where the absorbance (at 400 nm) of the enzyme-substrate solution was monitored and recorded over the course of 70 seconds at 10 second increments. This assay was used to determine the rate at which alkaline phosphatase can dephosphorylate p-nitrophenyl phosphate to p-nitrophenol, which then dissociates to phenolate ion, which causes the solution to turn yellow in a solution at

It has been said that if the universe is an elephant, then linear theory can only be used to describe the last molecule in the tail of the elephant and chaos theory must be used to understand the rest. Or, in other words, linear systems in nature are relatively
the reactions of chemicals, the rate of growth of a population, spring mass systems, bending of beams, the conduction of heat in a rod or in a slab etc. The mathematical formulations of all of the problems give rise to differential equations. Basically, most of the differential equations involving physical phenomena are nonlinear. It is simple to solve the differential equations which are linear but the solution of nonlinear equations are laborious and in some cases it is impossible to solve them analytically
success of all operations. However, it depends on the ability to make sense of the operational environment and to anticipate those factors that influence operations, both negatively and positively. Unfortunately, the structure and behavior of the systems that commonly comprise these factors suggest that making sense of operational environments is a “wicked problem”. A systematic examination of the population, the insurgency, and the counterinsurgent using the eight OE variables is critical to the
Hazard mitigation is an important plan for societies and communities to devise, that can prepare them for various types of hazards. The mitigation process involves actions that can help to reduce or eliminate the risks associated with hazards. The process can have many positives to it, and with a mitigation plan in place, states will be safer and ready for anything. With any plan, hazard mitigation has certain tools involved. The tools are Preventions, Property Protection, Public Education and Awareness
Theory Description The chaos theory is a part of the broader Systems Theory. The systems theory simply states that small systems are a part of a larger, complex system. Being that they are open rather than closed, the smaller systems are able to continuously interact with each other making them interdependent. Open systems allow for chaos to exist because boundaries are always changing and being defined and redefined (Bussolari & Goodell, 2009). Chaos Theory is a relatively new theory to the Social
multiple complex systems. Some everyday examples of complex systems are the brain, immune system, insect colonies, and even social networks such as Facebook and twitter. So what exactly do all these have in common in order to be a complex system? First is the fact that each one has a large amount of simple components that work together by communication through signals without being under leadership. But not all systems are exactly the same so we can break it down further into chaotic systems, complex adaptive
My passion for controlling mechanical systems can be pinpointed to when I exposed to a Legos Mindstrom kit back in middle school. Since then I have had a diverse undergraduate career where I tried to pursue many different field but I’ve found the field of control systems to be the most interesting. The Given my undergraduate and work experience I believe that graduate school will be the next logical step on the path to become an engineering leader in this field. I started college at UC Santa Cruz
of building a computer system that realistically models human thinking. The ethics of realizing such a dream are widely debated. Many believe it would be an extremely dangerous thing to accomplish, but that hasn’t stopped many from trying. The two main systems that have been developed so far that come closest to accomplishing this goal are neural networks and fuzzy logic control systems. This paper will only concern itself with the latter. Fuzzy logic control systems are designed to mimic
offers a host of new possibilities together with the advantages of previous incarnations. (McCormack & Jones, 1998) In just a few years the World Wide Web (WWW) has transformed communication, scholarship, and business. The idea of a global information system and the ease with which it can be used means that the Web has captured the imagination of more people than any other computer innovation. (McCormack & Jones, 1998) The possibility for using the Web for instruction has generated a great interest among
supralinear by de la Torre et al. (2000a) who reported unexpectedly high drug exposures (measured as AUCplasma for MDMA) and diastolic blood pressure increases in two volunteers given 150 mg MDMA. While pharmacokinetic data suggest MDMA has nonlinear kinetics, there is no clear evidence of supralinear relationships between dose and blood pressure or heart rate. In fact, there may be less increase in heart rate after higher doses. The tendency toward less heart rate increase with higher dose
expose some basic characteristics of the artwork which came out of this era. I will then examine the subsequent rise of Christianity, and how this radical change in the belief system affected the artwork which we see, in turn, from this era. Rational doubt sharply separated the Greek system of beliefs from other systems based on religious notions. The effect it had in Classical society was to sweep away convoluted magical explanations and replace them with the mechanism of logic. In societies

strengths, support systems and goals. It is based on the assessment of her physiological, social, emotional systems. In order to accomplish the goals and objectives, the General Systems Theory will be utilized to assist and guide the APRN in assessing and recognizing the problems present in the various aspects of her life and formulating interventions that will assist, guide, and direct her towards resolutions, health, wellness, acceptance and overall positive actuality. General Systems Theory is a theory
to management are sociotechnical systems, quantitative management, organizational behavior and systems theory. Each approach is unique, and each approach can be used in many types of management. The sociotechnical systems theory looks at two things. The social system in the work environment and the technical system in the work environment. The combination of these two things can lead to an organizations effectiveness in keep customers satisfied. The social system consists of the organizations workers
System tracts are areas of the lithosphere which have multiple interacting depositional systems. These system tracts are the arrangement of layers in a depositional sequence. The structure of a depositional sequence begins with a sequence boundary, followed by a lowstand systems tract, then a transgressive systems tract, a highstand systems tract, and a falling-stage systems tract, before finally reaching another sequence boundary. These strata were deposited at different points of transgressions

The System Theory The system theory helps one to understand adult with disabilities in terms of their needs, bio-psycho, social, spiritual, and cultural dimensions. This theory also helps one to understand the well-being of adults with disabilities and the quality of life they seek to achieve. (Hutchison, 2013) This theory depicts how family members, church congregation, careers, and government programs are interrelated parts that constitute adults with disabilities to live as close to normal
Part I Key Fundamentals of System Theories The systems theory can be a convenient way of thoughtful about the job of supervision. In real life situation it provides a framework for visualizing internal and external environmental factors as well as an incorporatedentire. It permitsacknowledgment of the proper place and function of subsystems. The systems inside which businessmen must run are necessarily complex. However, management via systems concepts fosters a way of thinking thathelps to dissolve
