description: This paper reported a general noninterferometric high-accuracy quantitative phase imaging (QPI) method for arbitrary complex valued objects. Given by a typical 4f optical configuration as the imaging system, three frames of small-window phase modulation are applied on the object Fourier spectrum so that redistributed intensity patterns are produced on the image plane, in which the object phase emerges at different degree. Then, an algebraic relationship that connects the object phase with the output intensity is established to provide us with an approximate closed form phase recovery. Further, an efficient iterative optimization strategy is developed to turn that approximate solution into an accurate one. Due to the linear convergence property of the iteration, a high accuracy phase recovery is achieved without requiring heavy iterations. The feasibility and accuracy of the proposed method are verified by both numerical simulations and experiments on diverse phase objects.

Unsettling times : Interior Salish religious responses to the 1872 earthquake in the Inland Northwest
Creators: name: Metcalfe-Chenail, Danielle
Publisher: name: University of British Columbia
Year: 2011

description: On December 14, 1872 at 9:40pm the Inland Northwest experienced its biggest earthquake since the eighteenth century. While seismologists have begun investigating this historic quake, scholars in the humanities have thus far ignored it. To begin to rediscover the human dimension of the earthquake, this paper explores how the Interior Salish the most numerous group in the region at the time experienced it as a spiritual event. To respond appropriately to it, it appears that they summoned their sumix (power helpers) at snyx w ám (winter dances); sought out Christian missionaries to perform rituals such as baptism and marriage; and turned to prophetic movements, an established part of their religious practice, which had taken on both Christian and anti-colonial elements during the nineteenth century. Many Interior Salish individuals used all three responses simultaneously, unsettling notions of "authentic" indigenous spirituality and demonstrating indigenous adaptability and flexibility. By drawing on more contemporary Interior Salish voices, this paper also contends that many aspects of their worldview have persisted since the 1872 earthquake.

description: The properties of the outer crust of non-accreting cold neutron stars are studied by using modern nuclear data and theoretical mass tables updating in particular the classic work of Baym, Pethick and Sutherland. Experimental data from the atomic mass table from Audi, Wapstra, and Thibault of 2003 is used and a thorough comparison of many modern theoretical nuclear models, relativistic and non-relativistic ones, is performed for the first time. In addition, the influences of pairing and deformation are investigated. State-of-the-art theoretical nuclear mass tables are compared in order to check their differences concerning the neutron dripline, magic neutron numbers, the equation of state, and the sequence of neutron-rich nuclei up to the dripline in the outer crust of non-accreting cold neutron stars.

description: In this paper, we solve the problem of predicting the next locations of the moving objects with a historical dataset of trajectories. We present a Next Location Predictor with Markov Modeling (NLPMM) which has the following advantages: (1) it considers both individual and collective movement patterns in making prediction, (2) it is effective even when the trajectory data is sparse, (3) it considers the time factor and builds models that are suited to different time periods. We have conducted extensive experiments in a real dataset, and the results demonstrate the superiority of NLPMM over existing methods.

description: With the global color symmetry model being extended to finite chemical potential, we study the density dependence of the local and nonlocal scalar quark condensates in nuclear matter. The calculated results indicate that the quark condensates increase smoothly with the increasing of nuclear matter density before the critical value (about 12$ρ_0$) is reached. It also manifests that the chiral symmetry is restored suddenly as the density of nuclear matter reaches its critical value. Meanwhile, the nonlocal quark condensate in nuclear matter changes nonmonotonously against the space-time distance among the quarks.

description: Die dem Beitrag zugrundeliegende Studie ist die erste Studie zum Anwendungsstand des betriebswirtschaftlichen Controllings im Online-Handel in der D-A-CH-Region. Dabei geht es im Kern um die Fragen, welche betriebswirtschaftlichen Controlling-Instrumente in welchem Ausmaß genutzt werden und ob Zusammenhänge zu Merkmalen der Unternehmensstruktur sowie zum betriebswirtschaftlichen Erfolg bestehen. Die Studie repräsentiert die Antworten von 53 Online-Händlern. Sie zeigt, dass Kurzfristige Erfolgsrechnung (KER) und Handelsspannenrechnung Standardinstrumente des betriebswirtschaftlichen Controllings sind, während, neuere Instrumente, wie Prozesskosten-, Kundendeckungsbeitrags- und Kundenlebenszyklusrechnung sowie Balanced Scorecard noch relativ wenig verbreitet sind. Online-Händler, die mehrere Absatzkanäle betreiben, nutzen zudem sehr häufig die Absatzkanalerfolgsrechnung. Es zeigt sich in der Tendenz, dass größere Unternehmen mit einer höheren Intensität betriebswirtschaftliches Controlling betreiben und dass eine höhere Nutzungsintensität der Handelsspannen- und Absatzkanalerfolgsrechnung den Betriebserfolg positiv beeinflusst.

description: A numerical solution is presented for the non-linear evolution equation that governs the dynamics of high parton density QCD. It is shown that thesolution falls off as $e^{-b/R}$ at large values of the impact parameter $b$. The power-like tail of the amplitude appears in impact parameter distributions only after the inclusion of dipoles of size larger than the target, a configuration for which the non-linear equation is not valid. The value, energy and impact parameterof the saturation scale $Q_s(y=\ln(1/x),b)$) are calculated both for fixed and running QCD coupling cases. It is shown that the solution exhibits geometrical scaling behaviour. The radius of interaction increases as the rapidity in accordance with the Froissart theorem. The solution we obtain differs from previous attempts, where an anzatz for $b$ behaviour was made. The solutions for running and fixed $\as$ differ. For running $\as$ we obtain a larger radius of interaction (approximately twice as large), a steeper rapidity dependence, and a larger value of the saturation scale.

title: A dialogue model of the resolution of inter-individual conflicts : implications for computer based collaborative learning
Creators: name: Joiner, Richard
Publisher: name: The Open University
Year: 1993

description: As a result of empirical research into the benefits of peer interaction for learning and development, there is growing interest in designing systems to support collaborative learning. How best to do this for classroom learning is still unclear, and the aim of this thesis is to marry theory with empirical study to produce a set of guide-lines for informing the design of computer based collaborative learning.

The resolution of inter-individual conflicts has long been proposed as a mechanism for learning in peer interaction and research indicates that in certain circumstances it does lead to learning. How this finding can be employed in the design of systems is problematic because researchers have typically not unpacked the notion of conflict and not explained how they are resolved.

To overcome this a dialogue model of the resolution of inter-individual conflicts in joint planning is proposed. There are three key components in this model; the Task Representation, the Task Focus and the Dialogue focus. Using this model I begin to differentiate between three different types of conflict. Conflicts are caused by Task Representation Differences, Intersection Differences or Task Focus Differences . All three types of interindividual difference can be resolved with a set of discourse transactions and a set of internal resolution procedures. I propose that the resolution of all three can facilitate joint planning and subsequent individual planning.

Three experiments are reported which investigate these claims. The first experiment shows that pairs performed better than individuals in a planning task and this beneficial effect carries over to subsequent individual planning. The proposed model is used to investigate this facilitative effect. A corpus of inter-individual conflicts is reported. Most of the conflicts identified in this corpus are either intersection differences or task focus differences and evidence is reported which supports the claim that their resolution can lead to learning. The second and third experiments investigate the claims made from the model about task representation differences and evidence was found to support them. The research reported in this thesis is then related to the design of software to support collaborative learning by presenting a set of guide-lines for informing their design. The work also has important implications for developmental psychology and classroom practice. i
The p-value interpreted as the posterior probability of explaining the data: Applications to multiple testing and to restricted parameter spaces
Creators: name: Bickel, David R.
Publisher: name: Zenodo
Year: 2021

description: Failures to replicate the results of scientific studies are often attributed to misinterpretations of the p value. The p value may be interpreted as an approximate posterior probability, not that the null hypothesis is true but rather that it explains the data as well as the data-generating distribution. That posterior probability modifies the p value in the following two broad areas of application, leading to new methods of hypothesis testing and effect size estimation. First, when corrected for multiple comparisons, the posterior probability that the null hypothesis adequately explains the data overcomes both the conservative bias of corrected p values and the anti-conservative bias of commonly used false discovery rate methods. Second, the posterior probability that the null hypothesis adequately explains the data, conditional on a parameter restriction, transforms the p value in such a way as to overcome difficulties in restricted parameter spaces.

description: This paper considers stochastic convex optimization problems where the objective and constraint functions involve expectations with respect to the data indices or environmental variables, in addition to deterministic convex constraints on the domain of the variables. Although the setting is generic and arises in different machine learning applications, online and efficient approaches for solving such problems have not been widely studied. Since the underlying data distribution is unknown a priori, a closed-form solution is generally not available, and classical deterministic optimization paradigms are not applicable. State-of-the-art approaches, such as those using the saddle point framework, can ensure that the optimality gap as well as the constraint violation decay as $Ø\left(T^{-\frac{1}{2}}\right)$ where $T$ is the number of stochastic gradients. The domain constraints are assumed simple and handled via projection at every iteration. In this work, we propose a novel conservative stochastic optimization algorithm (CSOA) that achieves zero constraint violation and $Ø\left(T^{-\frac{1}{2}}\right)$ optimality gap. Further, the projection operation (for scenarios when calculating projection is expensive) in the proposed algorithm can be avoided by considering the conditional gradient or Frank-Wolfe (FW) variant of the algorithm. The state-of-the-art stochastic FW variants achieve an optimality gap of $Ø\left(T^{-\frac{1}{3}}\right)$ after $T$ iterations, though these algorithms have not been applied to problems with functional expectation constraints. In this work, we propose the FW-CSOA algorithm that is not only projection-free but also achieves zero constraint violation with $Ø\left(T^{-\frac{1}{4}}\right)$ decay of the optimality gap. The efficacy of the proposed algorithms is tested on two relevant problems: fair classification and structured matrix completion.

description: Extreme skin depth engineering (e-skid) can be applied to integrated photonics to manipulate the evanescent field of a waveguide. Here we demonstrate that e-skid can be implemented in two directions in order to deterministically engineer the evanescent wave allowing for dense integration with enhanced functionalities. In particular, by increasing the skin depth, we enable the creation of large gap, bendless directional couplers with large operational bandwidth. Here we experimentally validate two-dimensional e-skid for integrated photonics in a CMOS photonics foundry and demonstrate strong coupling with a gap of 1.44 μm.

description: We show that the solutions of the Bogomolny equations for the Abelian Higgs model on a two-dimensional torus, can be expanded in powers of a quantity epsilon measuring the departure of the area from the critical area. This allows a precise determination of the shape of the solutions for all magnetic fluxes and arbitrary position of the Higgs field zeroes. The expansion is carried out to 51 orders for a couple of representative cases, including the unit flux case. We analyse the behaviour of the expansion in the limit of large areas, in which case the solutions approach those on the plane. Our results suggest convergence all the way up to infinite area.

Quantum Experiments and Hypergraphs: Multi-Photon Sources for Quantum Interference, Quantum Computation and Quantum Entanglement

description: We introduce the concept of hypergraphs to describe quantum optical experiments with probabilistic multi-photon sources. Every hyperedge represents a correlated photon source, and every vertex stands for an optical output path. Such general graph description provides new insights for producing complex high-dimensional multi-photon quantum entangled states, which go beyond limitations imposed by pair creation via spontaneous parametric down-conversion. Furthermore, properties of hypergraphs can be investigated experimentally. For example, the NP-Complete problem of deciding whether a hypergraph has a perfect matchin can be answered by experimentally detecting multi-photon events in quantum experiments. By introducing complex weights in hypergraphs, we show a general many-particle quantum interference and manipulating entanglement in a pictorial way. Our work paves the path for the development of multi-photon high-dimensional state generation and might inspire new applications of quantum computations using hypergraph mappings.

description: Coulomb interactions of few ($ N $) electrons confined in a disk shaped quantum dot, with a large magnetic field $B=B^*$ applied in the z-direction (orthogonal to the dot), produce a fully spin polarized ground state. We numerically study the splitting of the levels corresponding to the multiplet of total spin $S=N/2$ (each labeled by a different total angular momentum $ J_z $) in presence of an electric field parallel to $ B $, coupled to $ S $ by a Rashba term. We find that the first excited state is a spin exciton with a reversed spin at the origin. This is reminiscent of the Quantum Hall Ferromagnet at filling one which has the skyrmion-like state as its first excited state. The spin exciton level can be tuned with the electric field and infrared radiation can provide energy and angular momentum to excite it.

description: Twisted mass fermions allow light quarks to be explored but with the consequence that there are mass splittings, such as between the neutral and charged pion. Using a direct calculation of the connected neutral pion correlator and stochastic methods to evaluate the disconnected correlations, we determine the neutral pion mass. We explore the dependence on lattice spacing and quark mass in quenched QCD. For dynamical QCD, we determine the sign of the splitting which is linked, via chiral PT, to the nature of the phase transition at small quark mass.

description: The study was carried out to explore the use of mixed (banana, carrot and apple) peel powder with wheat flour in the preparation of high fiber biscuits. The ; to study its effects of the mixed peel powder (MPP) on the nutritional quality and sensory characteristics of the biscuits were also studied. The mixed peel powder (MPP) was prepared through the process of drying and grinding. Biscuits were prepared from blend of whole wheat flour along with MPP using the traditional creamery method. Sensory evaluation was carried out using a group of trained panelists. MPP and prepared biscuits were analyzed for their proximate and mineral contents. All the obtained data were analyzed statistically to determine the level of significance of variation in observations. MPP was characterized by lower moisture content, protein and carbohydrate while having higher content of fat, fiber, ash and some other minerals (Fe, K, Mn, Mg and Ca) compared to wheat flour. Wheat flour when substituted with 5% of MPP resulted in better quality, nutritious and fiber enriched biscuits (carbohydrate 68.47%, protein 14.45%, fat 4.74%, ash 1.98% and fiber 3.00%). Fe, K, Mn and Ca contents were also found to be higher in the developed biscuit than the control biscuit made with wheat flour. The newly formulated biscuit was found to be more acceptable in terms of nutritional and sensory characteristics

description: We have calculated the radiation field, dust grain temperatures, and far infrared emissivity of numerical models of turbulent molecular clouds. When compared to a uniform cloud of the same mean optical depth, most of the volume inside the turbulent cloud is brighter, but most of the mass is darker. There is little mean attenuation from center to edge, and clumping causes the radiation field to be somewhat bluer. There is also a large dispersion, typically by a few orders of magnitude, of all quantities relative to their means. However, despite the scatter, the 850 micron emission maps are well correlated with surface density. The fraction of mass as a function of intensity can be reproduced by a simple hierarchical model of density structure.

description: During the last decade, the Brazilian economy was affected by two important recessive shocks. However, the spatiality of these shocks is still neglected by scholars and policy-makers. This study analyses these recessions’ spatial structure by applying elements of the regional resilience literature using spatial seemingly unrelated regressions (SUR) models. The results show significant heterogeneity in the territorial extension of crises led by the characteristics of the productive structure in regional resistance and more significant impacts of nationwide downturns on less diversified regions. This result raises concerns for local economies dependent on specialized production, which is typical of developing countries, mainly for the extractive areas.
Tracking sea lice : Lepeophtheirus salmonis, between host fish populations using stable carbon and nitrogen isotopes
Creators: name: Dean, Susan
Publisher: name: University of British Columbia
Year: 2011

description: This study was undertaken to assess the use of carbon and nitrogen stable isotope analyses as methods to identify source host fish populations of sea lice, Lepeophtheirus salmonis. The delta carbon signatures of parasitic copepodid sea lice used to infect cultured Atlantic salmon in the laboratory were found to be statistically indistinguishable from the delta carbon signatures of blood (ANOVA, p = 1.000) and mucus (ANOVA, p = 0.430) sampled from the wild pink salmon population from which the sea lice originated. As a result, delta carbon signatures show potential as tools to track the movement of sea lice between fish populations. In contrast, delta nitrogen analysis did not show such promise as the natal host fish, wild pink salmon, and novel host fish, cultured Atlantic salmon, between which sea lice were transferred during the study, did not display distinct isotope signatures and thus could not be differentiated. This study found that when applying stable isotope analysis as a method to studying the dispersal of sea lice (1) the blood and mucus of potential source host fish populations should be sampled when assessing their possible relationship to sampled sea lice, (2) sea lice in no later than the parasitic copepodid stage should be analysed, (3) sea lice should be given time to clear their guts of any host materials before analysis takes place, (4) sea lice sampled from the gills should not be not grouped with sea lice sampled from the body surface or fins, and (5) replication unit for sampled parasitic copepodids should be set at the individual and not host fish level. The application of stable carbon isotopes to tracking the movement of sea lice between host fish is a promising method for directly identifying sources of sea lice epizootics and of quantifying the exchange of sea lice between host fish populations.

description: Modern states are organized in multilevel governance structures with economic and political authorities dispersed across them. However, although there is relatively widespread consensus that this form of organization is preferable to a centralized authority, the same cannot be said about its jurisdictional design – that is, how to transfer authority from central states to both supra- and subnational levels. This lack of consensus also exists in contexts with explicit initiatives to strengthen political ties such as the European Union (EU), and even within EU member countries, a situation which is aggravated by the relative scarcity of contributions that measure the advantages and disadvantages of different territorial organizations. We explore these issues through a study of one EU country, Spain, whose provincial councils (diputaciones) are often the subject of debate and controversy due to their contribution to increasing public spending and their purported inefficiencies, corruption and lack of transparency. Specifically, we combine a variety of activity analysis techniques to evaluate how they impact on local government performance. Results suggest that, in general, the presence of a provincial council has a positive impact on local government performance, but when their activity levels are too high, the effect can become pernicious.

 Type species. Termitodius coronatus Wasmann 1894, by monotypy.
 Diagnosis. Length approximately 3.5-4.0 mm. Body of typical rhyparine appearance with strong dorsal carinae and elytron with an apical bulb and trichomes. Head with clypeus abruptly inflexed medially, submarginal lines and bead present, angulate medial tooth evident in ventral view only when head extended. Pronotum dorsally robust, usually distinctly lobed, lateral margin flared anteriorly; dorsal carinae of variable development, each carina broadened with bulbous at anterior margin (Fig. 7), carina simply broadened posteriorly, discolateral carina reduced on posterior 2/3. Metafemur long, slender, cylindrical, not notably widened apically. Meso- and metatibia elongate, circular in cross section, not flattened nor dilated toward apex. Mesotibia (Termitodius - type) apically truncate, complete terminal fringe of setae, apical spine small and perpendicular to tibial axis, second subapical spine on inner margin separated from apex by shallow notch, prominent in male (Fig. 4), weakly developed in female. Elytron elongate, approximately 3 times longer than wide; not distinctly parallel-sided, evenly rounded to terminal bulb.
 Distribution. Known only from Mexico and northern South America.
 Comments. This genus shares the Termitodius - type mesotibia only with Aschnarhyparus. They are readily distinguished based on differences in pronotal carinae (swollen anteriorly in Termitodius; not swollen in Aschnarhyparus), and in metatibial shape (elongate, cylindrical and not apically widened in Termitodius; shorter, flattened and distinctly widening to apex in Aschnarhyparus).

description: Electron microscopy stands out as electron waves providing higher spatial resolving power compared to their optical counterpart. Here we investigate theoretically the interaction of twisted electrons generated in transmission electron microscope (TEM) and magnetic impurity, in which the magnetic dipole moment is taken as a demonstration element. In addition to the usual optical phase, the inhomogeneous vector potential generated by the magnetic dipole moment makes additional contribution to the intrinsic orbital angular momentum of electrons, resulting in a Gouy phase shift. By interfering the outgoing twisted electron beam with a reference Gaussian-cylindrical wave, one can determine the magnitude and orientation of magnetic dipole directly via the rotational and deformed interference pattern. The obtained results demonstrate the usefulness of twisted electron beams for probing the atomic- and nanoscale magnetism of impurity by TEM and the proposed model provides the conceptual basis for future developments of the TEM method.

title: Visualisation of semantic relations between nodes in hypertext-based learning systems
Creators: name: Zhao, Zhengmai

description: The research described in this thesis is concerned with the design of hypertext-based learning systems. More specifically, it is concerned with investigating the effects of visualising semantic relations between nodes on learning in hypertext-based learning systems.

One of the most commonly cited problems with hypertext is the distraction that stems from the high level of learner control in hypertext systems. This might partly be responsible for the fact that there are few evaluations of hypertext in education which have shown the strength of hypertext over other media in terms of learning outcomes. In order to ease the problem of distraction so as to improve the application of hypertext in education, an approach employing visible link-types is proposed. It is hypothesised that labelling links explicitly with semantic relations between nodes can lower the learner's cognitive overheads in making navigational decisions so as to improve learning. It is also hypothesised that this kind of labelling can make the conceptual model of the knowledge domain intuitively clearer to the learner and thus facilitate learning.

A set of three empirical studies has been conducted to evaluate the effectiveness of the proposed approach in different situations, using different methodologies. The results found from these studies demonstrate that visualisation of semantic relations between nodes has potential for improving the use of hypertext for learning.

description: The density matrix renormalization group (DMRG) method and its applications to finite temperatures and two-dimensional systems are reviewed. The basic idea of the original DMRG method, which allows precise study of the ground state properties and low-energy excitations, is presented for models which include long-range interactions. The DMRG scheme is then applied to the diagonalization of the quantum transfer matrix for one-dimensional systems, and a reliable algorithm at finite temperatures is formulated. Dynamic correlation functions at finite temperatures are calculated from the eigenvectors of the quantum transfer matrix with analytical continuation to the real frequency axis. An application of the DMRG method to two-dimensional quantum systems in a magnetic field is demonstrated and reliable results for quantum Hall systems are presented.

description: Even though a wide range of the literature explores how governments target public goods strategically, only a handful of papers examine whether these electorally motivated distributive patterns have consequences for the real economy. With the use of Turkish electoral and firm-level data, this paper examines whether electoral factors affect the variation in power outages experienced by firms across Turkish regions. The findings demonstrate that sales of firms located in regions in which the incumbent party received more votes were disproportionately higher because these firms experienced relatively lower numbers and durations of power outages.

description: Sound scattering by a finite width beam on a single rigid body rotation vortex flow is detected by a linear array of transducers (both smaller than a flow cell), and analyzed using a revised scattering theory. Both the phase and amplitude of the scattered signal are obtained on 64 elements of the detector array and used for the analysis of velocity and vorticity fields. Due to averaging on many pulses the signal-to-noise ratio of the phases difference in the scattered sound signal can be amplified drastically, and the resolution of the method in the detection of circulation, vortex radius, vorticity, and vortex location becomes comparable with that obtained earlier by time-reversal mirror (TRM) method (P. Roux, J. de Rosny, M. Tanter, and M. Fink, {\sl Phys. Rev. Lett.} {\bf 79}, 3170 (1997)). The revised scattering theory includes two crucial steps, which allow overcoming limitations of the existing theories. First, the Huygens construction of a far field scattering signal is carried out from a signal obtained at any intermediate plane. Second, a beam function that describes a finite width beam is introduced, which allows using a theory developed for an infinite width beam for the relation between a scattering amplitude and the vorticity structure function. Structure functions of the velocity and vorticity fields deduced from the sound scattering signal are compared with those obtained from simultaneous particle image velocimetry (PIV) measurements. Good quantitative agreement is found.

description: This study investigates the impacts of airport activities on regional economies using annual data on all regions and 22 airports in New Zealand from 2001 to 2016. In addition to fixed effects estimation, the system generalized method of moments approach and the dynamic common correlated effects estimator are used to account for cross-sectional dependence, cross-regional heterogeneity and feedback effects. The study shows clear and consistent evidence that aviation activities positively affect regional economies, and that it is beneficial for policy-makers and airport owners in a region to promote aviation activities.

description: Populations of the Critically Endangered hawksbill turtle Eretmochelys imbricata in the Seychelles showed significant declines in the past. They have since recovered and nesting numbers are increasing because of increased protection and management intervention. Data on their nesting ecology on Cousine Island were collected and analysed for the breeding seasons from 2004/2005 to 2013/2014 with the aim of improving management methods. The findings indicate that the number of nesting individuals increased during the study period (from x̅ = 34.3 nesters between 2004 and 2009, to x̅ = 55.4 nesters between 2010 and 2014); however, the clutch frequency was relatively low compared with other study areas. Night-time nesting increased, most likely because of increased disturbances across the study period. Clutch sizes decreased significantly across the nesting season, and there was a significant drop in hatching success in clutch sizes exceeding 200 eggs. The predation rate and infertility rate each showed an increasing trend over time. Nests incubating in full sun showed the highest mean hatching success rate and had the shortest mean incubation duration. The present study provides insight into the species’ nesting ecology on Cousine Island and will better inform management decisions aimed at increasing hatching success and minimising threats such as beach erosion and predation.

description: There are three types of single or multimode fiber cable-RC (Russia-Canada), LC (London-Canada), SC (Singapore-Canada) which comes from TJ box (fiber joining box) as the endpoint of main Optical fiber cable (which can be at most 3456 core in general). TheRC or LC or SC cable is to be connected to the Media converter and a Utp cable is released from the Media converter and connected to any port of a Switch to activate the channel for passing the bandwidth though the activated line. Now our concern of for reduction of packet loss through the channel what benefit we will get of using switch with Gigabit SFP (Small Form-Factor Pluggable) module in comparing of using Media converter with or without SFP module.

description: This paper examines the effects of mobile money, a rather new innovation in Uganda’s financial sector landscape on aggregate economic activity and other macroeconomic variables. We first estimate the long-run effect of mobile money deposits and value of transactions on monetary aggregates using vector error correction (VEC) techniques. We then estimate the short-term effects of mobile money on selected macroeconomic variables using Structural Vector Autoregressive (SVAR) methods. Results show modest macroeconomic impacts: mobile money has moderate positive effects on monetary aggregates, the consumer price index, and private sector credit. Mobile money deposits do respond to changes in monetary policy instruments, signalling possible ameliorating effects for the conduct of monetary policy. These results provide evidence for policy makers to continue supporting the growth of mobile money platforms. In particular, policy makers should provide the policy and regulatory framework through which mobile money balances can become interest-bearing assets, as this will further strengthen the monetary policy transmission mechanism.
