Topics include manifolds, Riemannian geometry, Einstein’s equations, and three applications: gravitational radiation, black holes, and cosmology. Individual chapters, and potentially updated versions, can be found at http://itp.ucsb.edu/~carroll/notes/. NSF-ITP/97-147 gr-qc/9712019 .i Table of Contents 0.

  • This textbook covers all the standard introductory topics in classical mechanics, including Newton's laws, oscillations, energy, momentum, angular momentum, planetary motion, and special relativity. It also explores more advanced topics, such as normal modes, the Lagrangian method, gyroscopic motion, fictitious forces, 4-vectors, and general relativity. It contains more than 250 problems with detailed solutions so students can easily check their understanding of the topic. There are also over 350 unworked exercises which are ideal for homework assignments.

  • The solutions as presented generally just provide a guidance to solving the problems, rather than step by step manipulation, and leave much to the students to work out for themselves, of whom much is demanded of the basic knowledge in physics. Thus the series would provide an invaluable complement to the textbooks. The present volume for Mechanics which consists of three parts Newtonian Mechanics, Analytical Mechanics, and Special Relativity contains 410 problems.

  • In general, planning a special event or mass gathering should begin well in advance of the event. One of the first steps in planning an event is to bring together those who are hosting the event with those who are responsible for the public safety within the community. A multidisciplinary planning team or committee should be composed of the promoter or sponsor and any agency that holds a functional stake in the event (e.g., emergency management, law enforcement, fire and rescue, public works/utilities, public health, etc.).

  • Microelectromechanical systems (MEMS) have played an increasingly important role in sensor and actuator applications. And its key contribution is that it has enabled the integration of multi-components (i.e., electronics, mechanics, fluidics and etc) on a single chip and their integration has positive effects upon performance, reliability and cost. Compared to conventional electrostatic, thermal or magnetic actuating schemes, piezoelectric MEMS inkjet has the advantages of lower power consumption, lower voltage operation and relatively larger driving force....

  • Among the branches of classical physics, electromagnetism is the domain which experiences the most spectacular development, both in its fundamental and practical aspects. The quantum corrections which generate non-linear terms of the standard Maxwell equations, their specific form in curved spaces, whose predictions can be confronted with the cosmic polarization rotation, or the topological model of electromagnetism, constructed with electromagnetic knots, are significant examples of recent theoretical developments. ...

  • We Americans assume that our economic system will always scamper to provide us with the products we want. Special orders don’t upset us! I want my MTV! The truth is more complicated, especially in our education system, which is paid for by the students but controlled by the professoriate. Witness the perverse success of the bloated science textbook.

  • The seed points can be either a single pixel vector or a group of connected pixel vectors, which will be regarded as the same region in region growing. According to the aforesaid characteristics, there are two conditions for each pixel vector in the multi-spectral images to be selected to be a seed point. One is that the similarity between one pixel vector and the eight neighbors should be higher than one threshold. The other one is that the maximum relative Euclidean distance between a seed pixel vector and its eight neighbors should be smaller than a threshold. When the above...

  • It is relatively easy to distinguish PZ from TZ on transverse views so that simultaneous images of both transverse and sagittal images make far lateral biopsy easy. For the sagittal images only, after identifying the center of prostate such as the line of urethra, then, slowly rotate ultrasound probe to the lateral part, so that far lateral PZ would be identified just after disappearing from TZ. For patients with middle to large prostate, far lateral PZ on sagittal images may sometimes represent only the mid-base of the prostate.

  • We define relative Gromov-Witten invariants of a symplectic manifold relative to a codimension-two symplectic submanifold. These invariants are the key ingredients in the symplectic sum formula of [IP4]. The main step is the construction of a compact space of ‘V -stable’ maps. Simple special cases include the Hurwitz numbers for algebraic curves and the enumerative invariants of Caporaso and Harris. Gromov-Witten invariants are invariants of a closed symplectic manifold (X, ω).

  • The results of scenario S4 are presented in relative terms to scenario S3, i.e. the baseline scenario in year 2020. Therefore, this analysis isolates the effects of the abolition of the milk quota system in the EU-27 on specific economic indicators at MS and regional level. Key results of scenario S4 are that milk production increases by about 4.4% in the EU-27, and EU raw milk prices decline by 10%. Production of butter, skimmed and whole milk powder would increase by 5-6% while their prices would decline by about 6-7%. The production of cheese and fresh milk products...

  • ne of the most admired scientists of the last century, Linus Pauling, was once asked by a student: ‘Dr Pauling, how do you have so many good ideas?’ This was back in the 1930s, two or three decades before Pauling would win two Nobel Prizes, one for chemistry, the other for peace. Pauling thought for amoment and replied: ‘Well, David, I have a lot of ideas and throw away the bad ones.’ True enough for Pauling, no doubt. But of course his disarming answer begs more questions. Where do ideas come from? Why do some people have many more of them than others? How do you distinguish the...

  • Relatively recently, a Children’s Food Security Scale (CFSS) consisting only of the eight child-referenced items in the larger 18-item FSS has been validated by USDA/ERS. The CFSS can be scored and scaled to more directly depict the food security status of children in a household. This child-referenced scale has also been shown to yield higher prevalence of child hunger when administered separately than is obtained from the household-level FSS. 11 The eighteen questions comprising the FSS are shown in Table 1, with the eight items that make up the CFFS in the lower section.

  • The left hand column of pie charts in Figure 9 illustrates the relative size or “weight” of the four Intermediate and Predominantly Rural types in the Dijkstra-Poelman typology. (Predominantly Urban regions are excluded from this analysis11 ). It is immediately apparent that the Intermediate Accessible group of regions dominate the Intermediate and PR areas of Europe, accounting for almost exactly half the regions, more than a third of total area, and almost two-thirds of population.

  • The efficacy of health and nutrition interventions in develop- ing countries has been established for decades (for example, Gwatkin, Wilcox, and Wray 1980). Prospective studies in sev- eral settings showed that health interventions with or without supplementary foods caused children to thrive and survive better: studies in Narangwal, India (Kielmann and others 1978; Taylor, Kielmann, and Parker 1978); by the Institute for Nutrition for Central America and Panama (Delgado and others 1982); in Jamaica (Waterlow 1992); and in The Gambia (Whitehead, Rowland, and Cole 1976) are examples.
