Bill Tomlinson, University of California, Irvine Donald J. Patterson, Westmont College, and Bonnie Nardi, University of California, Irvine, delivered a curse titled 'ICS 5: Global Disruption and Information Technology' under Computing within LIMIT.. ICS 5 was one of the first online courses to be offered across the nine undergraduate campuses of the University of California system. The course has been offered three times to date: Winter 2015, Fall 2015, and Spring 2016. There were three primary curricular goals. The first was to educate students about the science of global change. The second was to educate students about the sociotechnical approach to technology design, which the three instructors have pursued throughout their careers. The third was to engage students in understanding and critiquing their own values and the processes by which such values may be brought to bear in the creation of sociotechnical solutions to global change. The authors structured the course as a descent into the problems in the early weeks, and then an ascent to solutions, ideas for solutions, and case studies of successes in the later weeks. A key premise of the course is that while technology may be able to address some aspects of sustainability, the core problem lies with the nature of current industrialized society. Despite their efforts, the authors found that many students struggled to grasp the core premise of LIMITS. Computing within LIMITS is critically important to the future of the computing discipline, and potentially a powerful transformative force in the world more broadly.

On the basis of Ref.\, the M x/G(M/G)/1 repairable queueing system with single delay vacation is discussed again. The following reliability problems of the service station are studied: (a) The probability that it fails at time t , i.e. its unavailability; (b) The expected failure number during the time interval (0,t\];; (c) The expected failure number during the ″server busy period″; (d) The expected downtime during the time interval (0,t\]. Some reliability results of the service station are obtained. These results would be interest to reliability analysts.
Speech processing is typically based on a set of complex algorithms requiring many parameters to be specified. When parts of the speech processing chain do not behave as expected, trial and error is often the only way...

In this paper, the creation and annihilation of turbulent eddies are described as elementary particles in the quantum field theory. An elementary particle mav be considered as a solid entity as it exists in quantum theory, but a turbulent eddy is often changed in size and shape with time due to its energy dissipation in a turbulent field. Therefore, in order to apply the method of the quantum field theory to the turbulent field by analogy, the entity of the same eddy should be defined firstly According to the linearized theory, the turbulent eddies with the similarity character in time duration may be considered as the entity of the same eddy, and the creation and annihilation of turbulent eddies without the similar characters are related to the interaction term in equation (2.6). Then, the creation operator and annihilation operator similar-to those in the quantum field theory are used to describe the state of turbulent eddy field. Finally, a 'Schrddinger' equation of turbulent eddies is formulated based upon the nonlinear terms in the original N- S equation. Thus, a new turbulent eddy interaction theory similar to the quantum field theory is obtained.
