Ebook "Dynamical decoupling in distance measurements by double electron-electron resonance" determines the optimal dynamical decoupling (DD) scheme for efficient reduction of electron spin coherence loss in model systems for spin labelled biomolecules depending on their particular relaxation behavior. Extending the nth order DD scheme to double electron-electron resonance (DEER) experiments require the addition of multiple pump pulses for ≠ 1.

Ebook "The mesoscopic theory of polymer dynamics" presented in this book explains in a consistent manner all dynamic effects (diffusion, neutron scattering, viscoelasticity, optical birefringence) observed in very concentrated solutions and melts of linear polymers from a macromolecular point of view. This monograph reconciles different approaches to polymer dynamics and reflects the modern situation in understanding the relaxation behaviour of the polymer systems.

The obtained solutions using differential evolution (DE) algorithm (upper bound), where its parameters are tuned by response surface methodology, are compared with exact solutions and computed lower bounds by linear relaxation technique to prove the efficiency of proposed DE algorithm.

In this paper we introduce two strategies for picking relaxation parameters to control the semiconvergence behavior of a sequential block-iterative method. A convergence analysis is presented. We also demonstrate the performance of our strategies by examples taken from tomographic imaging.

The management of the electrical and electronic waste (WEEE) problem in the uncertain environment has a critical effect on the economy and environmental protection of each region. The considered problem can be stated as a fuzzy non-convex optimization problem with linear objective function and a set of linear and non-linear constraints. The original problem is reformulated by using linear relaxation into a fuzzy linear programming problem.

The problem of finding a fundamental cycle basis with minimum total cost in a graph arises in many application fields. In this paper we present some integer linear programming formulations and we compare their performances, in terms of instance size, CPU time required for the solution, and quality of the associated lower bound derived by solving the corresponding continuous relaxations.

The calculations are based on the linearized Boltzmann equation (BE) and the relaxation time approximation, assuming the scattering by acoustic phonons to be quasi-elastic. We consider three physically distinct temperature ranges with respect to phonon scattering: the Bloch-Gruneisen ¨ (BG), equipartition (EP), and inelastic regimes.

We demonstrate the interest of expanded beam microlenses (around 55 µm of mode field diameter) to relax positioning tolerances and to decrease reflectance in single mode fiber to fiber interconnections . We also point out the interest of micro-lenses of very small mode field diameter (around 2 µm) to improve coupling efficiency in specialty fibers and integrated waveguides for non linear effects based functions and for sensors applications at a wavelength of 1.55 µm.

This study uses what Cresswell (2003) refers to as a ‘mixed methods approach’, one that combines quantitative and qualitative data collection and a ‘sequential explanatory strategy’ in which the collection and analysis of the quantitative data is followed by the collection and analysis of the qualitative data (p 215).

It is promising, however, that a a majority of male and female respondents perceive social media as an enabler for women’s empowerment. This is coupled with the robust growth of social media usage among youth in the Arab region. If lessons are to be drawn from youth utilization of social media during the recent popular movements in the Arab world, then in light of the growing sense of empowerment today, the strong positive perceptions shown in our survey suggest that social media can continue to play an important role in empowering Arab women in the future. However, this will only...

This paper describes the compilation of the first truly comprehensive historical public debt database (HPDD) covering gross government debt-to-GDP ratios for nearly the entire country membership of the IMF and spanning a long time period. The HPDD covers 174 countries and starts from 1880 for most G-7 countries and a few other advanced and emerging economies, and from 1920 for additional advanced and emerging economies. 2 For low-income countries (LICs), data coverage generally starts in 1970.

Film scholar and author Shoma Chatterji (Subject: Cinema, Object: Women, 1998) says, “Women in Hindi cinema have been decorative objects with rarely any sense of agency being imparted to them. Each phase of Hindi cinema had its own representation of women, but they were confined largely to the traditional, patriarchal frame-work of the Indian society. The ordinary woman has hardly been visible in Hindi cinema.” vi To understand this portrayal in much more depth, we need to have a look at some crucial glimpses which defined the role of women in Hindi films.

Serving New Zealand’s future needs means we have to make sure that the education system performs well for Māori and that the needs of Māori children in education are met. This report describes the history of education policy and developments for Māori, sets out some leading research and statistics, and describes the role of the various government agencies involved in education. Under the Ministry of Education’s Ka Hikitia – Managing for Success strategy, there are many initiatives and programmes to lift Māori participation, engagement, and achievement.

'Accessible' means that not all the available resource can be used because of physical constraints (a large part of the aquifers, flood water greater than needed for reservoirs replenishment), inappropriate location or timeliness, inappropriate quality, and because part of the annual service flow has to be left to the ecosystem for its own needs.
