description: Micro Electro Mechanical Systems refer to formation of electro-mechanical systems in the scales of micrometers. In terms of popularity of the technology and interest toward this, Borovic et al have mentioned in their recent paper[28]:“MEMS are the next step in the silicon revolution that began 40 years ago. Currently, MEMS are in an exponential growth stage such as that enjoyed by thesemiconductor industry.”.While MEMS technology enables significant reduction in physical size of various types of sensors, actuators and systems by several orders of magnitude, does not necessarily imply less system complexity. In fact, modelling or identifying characteristics of such devices can be difficult as a combination of advanced modelling techniques and Finite Element analysis would be necessary to obtain an appropriate mathematical model approximation.In the context of MEMS actuator technology, the electrostatic microactuators have received much attention for real applications such as DLP technology and research work on more advanced control algorithms. Traditionally, such devices have been controlled in an open loop fashion but problems with the so-call ed pull-in phenomenon (a form of instabilityin the system due to the electrostatic forces that arise between the plate of the microactuator) limits performance.Feedback control has enabled improved performance, although still most works exist in research labs rather than already implemented and in mass production.The work presented in this dissertation relates to voltage control of parallel-plate electro-static microactuator devices, with the particular aim of extending the travelling range of the microactuator plates beyond the “pull-in” condition thus taking advantage of increase range of operation (which is useful when finer motion resolution is required in applications such as DLP etc.). The particular aim is studying the capabilities of state feedback related Sliding Mode Control to improving system performance and robustness to uncertainty compared to the linear control equivalents. Simulation studies are performed with the help of Matlab and Simulink.

description: Surface waves on Earth's magnetopause have a controlling effect upon global magnetospheric dynamics. Since spacecraft provide sparse in situ observation points, remote sensing these modes using ground-based instruments in the polar regions is desirable. However, many open conceptual questions on the expected signatures remain. Therefore, we provide predictions of key qualitative features expected in auroral, ionospheric, and ground magnetic observations through both magnetohydrodynamic theory and a global coupled magnetosphere-ionosphere simulation of a magnetopause surface eigenmode. These show monochromatic oscillatory field-aligned currents, due to both the surface mode and its non-resonant Alfvén coupling, are present throughout the magnetosphere. The currents peak in amplitude at the equatorward edge of the magnetopause boundary layer, not the open-closed boundary as previously thought. They also exhibit slow poleward phase motion rather than being purely evanescent. We suggest the upward field-aligned current perturbations may result in periodic auroral brightenings. In the ionosphere, convection vortices circulate the poleward moving field-aligned current structures. Finally, surface mode signals are predicted in the ground magnetic field, with ionospheric Hall currents rotating perturbations by approximately (but not exactly) 90° compared to the magnetosphere. Thus typical dayside magnetopause surface modes should be strongest in the East-West ground magnetic field component. Overall, all ground-based signatures of the magnetopause surface mode are predicted to have the same frequency across L-shells, amplitudes that maximise near the magnetopause's equatorward edge, and larger latitudinal scales than for field line resonance. Implications in terms of ionospheric Joule heating and geomagnetically induced currents are discussed.

description: Improving productivity of cocoa farms while ensuring forests sustainability through cocoa agroforestry is increasingly gaining the attention of policy makers. Using data from cocoa farmers in rural areas of Southern Ghana, the present study analyzes farmer perceptions on economic and ecological benefits of cocoa agroforestry shade levels with non-parametric tests, and economic performance of cocoa agroforestry shade levels with a cost-benefit modeling approach. The results from the study show that apart from market forces, farmers’ ecological perceptions play a crucial role in the establishment of agroforestry shade levels. There is also evidence to suggest that the medium shade cocoa agroforestry has a higher economic performance. Policies that promote awareness creation and increase knowledge on cocoa agroforestry shade levels are essential ingredients for forest sustainability in sub-Saharan Africa.

description: We present the first application of a recently-developed effective theory of jet propagation in matter SCETG to inclusive hadron suppression in nucleus-nucleus collisions at the LHC. SCETG-based splitting kernels allow us to go beyond the traditional energy loss approximation and unify the treatment of vacuum and medium-induced parton showers. In the soft gluon emission limit, we establish a simple analytic relation between the QCD evolution and energy loss approaches to jet quenching. We quantify the uncertainties associated with the implementation of the in-medim modification of hadron production cross sections and show that the coupling between the jet and the medium can be constrained with better than 10% accuracy.

description: Dry tropical forests in arid lands cover large areas in Brazil, but few studies report the total biomass stock showing the importance of height measurements, in addition to applying and comparing local and pan-tropical models. Here, we use a biomass data set of 500 trees and shrubs, covering 15 species harvested in a management plan in the state of Pernambuco, in Brazil. We seek to develop local models and compare them with the equations traditionally applied to dry forests – showing the importance of tree height measurements. Due to the non-linear relationships with the independent variables of the tree, we used a nonlinear least squares modeling technique when adjusting models, we adopted the cross-validation procedure. In summary, our above-ground biomass data set is best represented by the Schumacher-Hall equation: exp [3.5336 + 1.9126 × log (D) + 1.2438 × log (Ht)], which shows that height measurements are essential to estimate accurately biomass. The biggest prediction errors observed when testing pan-tropical models in our data demonstrated the importance of developing new local models and indicated that careful considerations should be made if generic “pan-tropical” models without height measurements are planned for application in dry forests in Brazil.

description: This report outlines the full work on the final year project. The project’s title is ‘CAD for robust control using the QFT design method ’. The aim of the project is to develop software tools, suitable for the robust control design of highly uncertain SISO systems. The design of these systems is based on I Horowitz’ s QFT method. This is a frequency domain loop-shaping design technique, which is fully described in Chapter 2. The report is a step-by-step guide to the design. It includes anintroduction to control and robust systems, an explanation of the QFT method, and the problem definition of the design using an illustrative example. It continues with designs of phase lead and lag compensators via graphical techniques. Next the application of optimisation methods for the design of optimal PD and PID controllers is discussed. Designing an appropriate pre-filter completes the design procedure. Finally, a number of simulations show that the design techniquewas successful and meets the given specifications. The report concludes with a summary of the project work and its results and suggests future directions, which can be followed in order to improve certain aspects of the design. The Appendix summarises aspects of the theories used for the purposes of the project and a list of Matlab files created and used.

description: Recently, Duvall and Hanasoge ({\it Solar Phys.} {\bf 287}, 71-83, 2013) found that large distance $[Δ]$ separation travel-time differences from a center to an annulus $[δt_{\rm{oi}}]$ implied a model of the average supergranular cell that has a peak upflow of $240\rm{ms^{-1}}$ at a depth of $2.3\rm{Mm}$ and a corresponding peak outward horizontal flow of $700\rm{ms^{-1}}$ at a depth of $1.6\rm{Mm}$. In the present work, this effect is further studied by measuring and modeling center-to-quadrant travel-time differences $[δt_{\rm{qu}}]$, which roughly agree with this model. Simulations are analyzed that show that such a model flow would lead to the expected travel-time differences. As a check for possible systematic errors, the center-to-annulus travel-time differences $[δt_{\rm{oi}}]$ are found not to vary with heliocentric angle. A consistency check finds an increase of $δt_{\rm{oi}}$ with the temporal frequency $[ν]$ by a factor of two, which is not predicted by the ray theory.

description: We present a site-percolation model based on a modified FCC lattice, as well as an efficient algorithm of inspecting percolation which takes advantage of the Markov stochastic theory, in order to study the percolation threshold of carbon nanotube (CNT) fibers. Our Markov-chain based algorithm carries out the inspection of percolation by performing repeated sparse matrix-vector multiplications, which allows parallelized computation to accelerate the inspection for a given configuration. With this approach, we determine that the site-percolation transition of CNT fibers occurs at p_c =0.1533+-0.0013, and analyze the dependence of the effective percolation threshold (corresponding to 0.5 percolation probability) on the length and the aspect ratio of a CNT fiber on a finite-size-scaling basis. We also discuss the aspect ratio dependence of percolation probability with various values of p (not restricted to p_c).

description: We present work in progress using the Logarithmic Linear Relaxation (LLR) density of states algorithm to analyse first-order phase transitions in pure-gauge SU(N) Yang--Mills theories, focusing on N = 4 and 6. By using the LLR algorithm we aim to avoid super-critical slowing down at such transitions. Motivation for this study comes from composite dark matter models, which may feature a first-order confinement transition in the early Universe that would produce a background of gravitational waves. Improving our understanding of these phase transitions will help probe these models using observations from future gravitational-wave observatories. In addition to the confinement transition, we also analyze bulk phase transitions of the lattice theories, which feature much larger latent heat.

description: Well-sampled optical and radio light curves of BL Lacertae in B, V, R, I bands and 4.8, 8.0, 14.5 GHz from 1968 to 2014 were presented in this paper. A possible $1.26 \pm 0.05$ yr period in optical bands and a $7.50 \pm 0.15$ yr period in radio bands were detected based on discrete correlation function, structure function as well as Jurkevich method. Correlations among different bands were also analyzed and no reliable time delay was found between optical bands. Very weak correlations were detected between V band and radio bands. However, in radio bands the variation at low frequency lagged that at high frequency obviously. The spectrum of BL Lacertae turned mildly bluer when the object turned brighter, and stronger bluer-when-brighter trends were found for short flares. A scenario including a precessing helical jet and periodic shocks was put forward to interpret the variation characteristics of BL Lacertae.

description: Fluid-suspended microorganisms have evolved different swimming and feeding strategies in order to cope with an environment dominated by viscous effects. For instance ciliated organisms rely on the collective motion of flexible appendices to move and feed. By performing a non-reciprocal motion, flexible filaments can produce a net propulsive force, or pump fluid, in the absence of inertia. Inspired by such fundamental concept, we propose a strategy to produce macroscopic pumping and mixing in creeping flow. We measure experimentally the net motion of a Newtonian viscous fluid induced by the reciprocal motion of a flapper. When the flapper is rigid no net motion is induced. In contrast, when the flapper is made of a flexible material, a net fluid pumping is measured. We quantify the effectiveness of this pumping strategy and show that optimal pumping is achieved when the length of the flapper is on the same order as the elasto-hydrodynamic penetration length. We finally discuss the possible applications of flexible impellers in mixing operations at low Reynolds numbers.

description: A Reflectance Transformation Imaging technique (RTI) realized by multi-rotor Unmanned Aerial Vehicles (UAVs) with a focus on deployment in difficult to access buildings is presented in this letter. RTI is a computational photographic method that captures a surface shape and color of a subject and enables its interactive re-lighting from any direction in a software viewer, revealing details that are not visible with the naked eye. The input of RTI is a set of images captured by a static camera, each one under illumination from a different known direction. We present an innovative approach applying two multi-rotor UAVs to perform this scanning procedure in locations that are hardly accessible or even inaccessible for people. The proposed system is designed for its safe deployment within real-world scenarios in historical buildings with priceless historical value.
Grooming interactions and cooperation in wild Barbary macaques (Macaca sylvanus)

description: The study of cooperation has been crucial to research on the evolution of socialliving in human and animal societies. Grooming interactions have been used as model toinvestigate the exchange of services in animals. Using both established and novelmethodologies, this thesis examines grooming interactions and cooperation in twopopulations of wild Barbary macaques living in the Middle Atlas Mountains of Morocco.It is important to have a comprehensive idea of the costs and benefits of groominginteractions, and of the effect of grooming interactions on the anxiety of the groomingpartners. This thesis showed that, contrary to previous studies, anxiety increased aftergrooming interactions in both the donor and recipient. This highlights the need to furtherinvestigate the link between grooming and emotions. Individuals may also affect thegrooming interactions of other group members. This thesis showed that individualsbenefit from disrupting grooming interactions of group members by gaining groomingopportunities for themselves and by stopping the group members from grooming eachother, although grooming disruptions may be risky. Monkeys may affect others’grooming interactions to favour their own social and dominance positions. A key aspectof this thesis was also to assess whether grooming is reciprocated in the short-term andwhich type of reciprocity (i.e. direct, indirect and generalised) play a role in theexchanges of grooming. This study showed that direct but not indirect and generalisedreciprocity play a role in the exchange of grooming. While there is a wide range ofevidence that direct reciprocity plays a role in the exchange of services in animals, thereis little evidence of indirect and generalised reciprocity. Additionally to exchanginggrooming for grooming, animals also exchange grooming for other services such astolerance around food resource and support during agonistic interactions. In this thesis, no evidence of short-term contingency between the exchange of grooming and foodtolerance was found. The exchanges of services may be little affected by recent singleevents, and mechanisms involving an emotional mediation based on long-term socialbonds between partners may play a more important role. The capacity to make effectivechoices among potential social partners is an important social skill, as choosing the bestavailable partner improves the chances to establish successful cooperative interactions.This thesis highlighted, to some extents, the importance of factors such as tolerance andrelationship quality between partners, in the performances of individuals and their choiceof partners to solve a cooperative task. Tolerant relationships may have been aprerequisite for the evolution of cognitively complex cooperation. Testing acomprehensive framework of predictions, this thesis brings novel contributions to theunderstanding of grooming interactions and cooperation in wild Barbary macaques

description: It is well known that there are black hole and the cosmological horizons for the Reissner-Nordström-de Sitter spacetime. Although the thermodynamic quantities on the horizons are not irrelevant, they satisfy the laws of black hole thermodynamics respectively. In this paper by considering the relations between the two horizons we give the effective thermodynamic quantities in $(n+2)$-dimensional Reissner-Nordström-de Sitter spacetime. The thermodynamic properties of these effective quantities are analyzed, moreover, the critical temperature, critical pressure and critical volume are obtained. We carry out an analytical check of Ehrenfest equations and prove that both Ehrenfest equations are satisfied. So the spacetime undergoes a second order phase transition at the critical point. This result is consistent with the nature of liquid--gas phase transition at the critical point, hence deepening the understanding of the analogy of charged dS spacetime and liquid--gas systems.

The wavelength tuning is achieved by horizontal displacement of the diffraction grating about an optimal pivot point. The compact design increases the robustness and passive stability of the ECDL and the stiff but light-weight diffraction grating-arm reduces the susceptibility to low-frequency mechanical vibrations. The linewidth of the ECDL is ~360 kHz. We use the 671 nm ECDL, without any additional power amplification, for laser cooling and trapping of lithium atoms in a magneto-optical trap. This simple, low-cost ECDL design using off-the-shelf laser diodes without anti-reflection coating can also be adapted to other wavelengths.

description: Context. Prominence oscillations have been mostly detected using Doppler velocity, although there are also claimed detections by means of periodic variations in half-width or line intensity. However, scarce observational evidence exists about simultaneous detection of oscillations in several spectral indicators. Aims. Our main aim here is to explore the relationship between spectral indicators, such as Doppler shift, line intensity, and line half-width, and the linear perturbations excited in a simple prominence model. Methods. Our equilibrium background model consists of a bounded, homogeneous slab, which is permeated by a transverse magnetic field, having prominence-like physical properties. Assuming linear perturbations, the dispersion relation for fast and slow modes has been derived, as well as the perturbations for the different physical quantities. These perturbations have been used as the input variables in a one-dimensional radiative transfer code, which calculates the full spectral profile of the hydrogen H-alpha and H-beta lines. Results. We have found that different oscillatory modes produce spectral indicator variations in different magnitudes. Detectable variations in the Doppler velocity were found for the fundamental slow mode only. Substantial variations in the H-beta line intensity were found for specific modes. Other modes lead to lower and even undetectable parameter variations. Conclusions. To perform prominence seismology, analysis of the H-alpha and H-beta spectral line parameters could be a good tool to detect and identify oscillatory modes.

description: The generation of organic particle beams is studied in combination with photoionization using uv radiation at 266 nm and vuv light at 157 nm. Single-photon ionization with pulsed vuv light turns out to be sensitive enough to detect various large neutral biomolecular complexes ranging from metal-amino acid complexes to nucleotide clusters and aggregates of polypeptides. Different biomolecular clusters are shown to exhibit rather specific binding characteristics with regard to the various metals that are co-desorbed in the source. We also find that the ion signal of gramicidin can be increased by a factor of fifteen when the photon energy is increased from 4.66 eV to 7.9 eV.

description: This letter describes a method for autonomous aerial cinematography with distributed lighting by a team of unmanned aerial vehicles (UAVs). Although camera-carrying multi-rotor helicopters have become commonplace in cinematography, their usage is limited to scenarios with sufficient natural light or of lighting provided by static artificial lights. We propose to use a formation of unmanned aerial vehicles as a tool for filming a target under illumination from various directions, which is one of the fundamental techniques of traditional cinematography. We decompose the multi-UAV trajectory optimization problem to tackle non-linear cinematographic aspects and obstacle avoidance at separate stages, which allows us to re-plan in real time and react to changes in dynamic environments. The performance of our method has been evaluated in realistic simulation scenarios and field experiments, where we show how it increases the quality of the shots and that it is capable of planning safe trajectories even in cluttered environments.
Graphene Cardboard: from Ripples to Tunable Metamaterial

description: Recently graphene was introduced with tunable ripple texturing, a nanofabric enabled by graphene's remarkable elastic properties. However, one can further envision sandwiching the ripples, thus constructing composite nanomaterial, graphene cardboard. Here the basic mechanical properties of such structures are investigated computationally. It turns out that graphene cardboard is highly tunable material, for its elastic figures of merit vary orders of magnitude, with Poisson ratio tunable from 10 to -0.5 as one example. These trends set a foundation to guide the design and usage of metamaterials made of rippled van der Waals solids.

description: Работа является продолжением серии статей в журнале «Аридные экосистемы» о комплексных экологических исследованиях в бассейне Нижней Волги, начатых в 2014 г. с целью изучить современное состояние наземных экосистем и выявить тенденции трансформации природной среды и ответных реакций наземных экосистем под воздействием изменения климата и антропогенных факторов. Работы проводились по собственной оригинальной двухэтапной методике оценки нарушений в наземных экосистемах при изменении обводненности территории. На первом этапе устанавливалось наличие возможных изменений в обводненности территорий по анализу изменений многолетних климатических и гидрологических данных. На втором этапе происходила оценка степени нарушений экосистем и ландшафтов по совокупности различных биологических показателей. Для Низовьев Волги выявлены основные причины изменения абиотических (гидролого-климатических) компонентов экосистем, влияющих на трансформацию ландшафтов. Определены основные причины изменения отдельных компонент наземных экосистем, связанные с повышением расходов зимней межени и зимними сбросами, которые наряду с климатическими изменениями способствуют увеличению оглеения почв по всему профилю и деградации пойменных экосистем.

Surface diffuseness correction in global mass formula

description: By taking into account the surface diffuseness correction for unstable nuclei, the accuracy of the macroscopic-microscopic mass formula is further improved. The rms deviation with respect to essentially all the available mass data falls to 298 keV, crossing the 0.3 MeV accuracy threshold for the first time within the mean-field framework. Considering the surface effect of the symmetry potential which plays an important role in the evolution of the "neutron skin" toward the "neutron halo" of nuclei approaching the neutron drip line, we obtain an optimal value of the symmetry energy coefficient J=30.16 MeV. With an accuracy of 258 keV for all the available neutron separation energies and of 237 keV for the alpha-decay Q-values of super-heavy nuclei, the proposed mass formula is particularly important not only for the reliable description of the r-process of nucleosynthesis but also for the study of the synthesis of super-heavy nuclei.
