description: This paper has two aims, one theoretical and the other empirical. At the theoretical level, we advance an interpretation of the apparent inability of models based on rational expectations to explain the time evolution of exchange rates. The interpretation is based on the inadequate treatment of the different time frequencies with which new information on the different variables that affect the foreign exchange markets becomes available. At the empirical level, we attempt to re-examine the effectiveness of controls on capital movements, during a period in which these were used in Italy; moreover we analyse the effectiveness of official foreign exchange interventions.

description: In this paper, AlGaAs/InGaAs pseudomorphic HEMTs have been submitted to DC life-tests in impact ionisation regime with and without thermal stress. Control devices present an identical and steep shape of the on-state breakdown locus while aged devices present a large dispersion of this characteristic. It seems that some slight modification of the surface properties and/or micro-defects located in the gate-drain region affect the on-state breakdown voltage loci measured with a gate current of 0.13mA/mm. After the two life-tests, the temperature evolution of the surface leakage contribution to the reverse gate current has increased while impact ionisation current remains unchanged. This result is confirmed by a weak temperature dependence of the on-state breakdown voltage measured with a gate current of 1mA/mm. These slight modifications of the surface properties do not affect the reliability of this technology.

description: Access to transport infrastructure generates a range of benefits to the agriculture sector; many of which are difficult to measure directly. In this study, we use hedonic regression analysis of farm-level data to examine the contribution of transport infrastructure to the value of farmland traded between 2009 and 2011 through its impact on farm productivity. We show that a one per cent reduction in the cost of transportation between farms and ports leads to a 0.33 per cent increase in land prices, and there is no significant difference between rail and road transportation at the aggregate level. Moreover, the benefits generated by particular types of infrastructure services vary between industries and with farm size, suggesting there are multiple channels through which public infrastructure influences agricultural production. Our findings help to inform future investment decisions in Australia and in other countries by providing new evidence regarding the benefits of existing transport infrastructure.

description: Canada’s large-scale contribution to the Great War generated wartime pride and post-war nationalism. The scale of effort and its resulting costs also bred deep social cleavages that marked the country for generations to come. The army, at first consisting mostly of British-born recent immigrants, grew into a massive national endeavour. Well-led by British and Canadian officers, it played a disproportionate role in achieving victory. The architecture of memory in Canada is still dominated by the First World War, from Ottawa’s Peace Tower and National War Memorial to smaller community cairns and monuments.

description: In this work we study certain invariant measures that can be associated to the time averaged observation of a broad class of dissipative semigroups via the notion of a generalized Banach limit. Consider an arbitrary complete separable metric space $X$ which is acted on by any continuous semigroup $\{S(t)\}_{t \geq 0}$. Suppose that $§(t)\}_{t \geq 0}$ possesses a global attractor $\mathcal{A}$. We show that, for any generalized Banach limit $\underset{T \rightarrow \infty}{\rm{LIM}}$ and any distribution of initial conditions $\mathfrak{m}_0$, that there exists an invariant probability measure $\mathfrak{m}$, whose support is contained in $\mathcal{A}$, such that $$ \int_{X} ϕ(x) d\mathfrak{m} (x) = \underset{T\to \infty}{\rm{LIM}} \frac{1}{T}\int_0^T \int_X ϕ(S(t) x) d \mathfrak{m}_0(x) d t, $$ for all observables $ϕ$ living in a suitable function space of continuous mappings on $X$. This work is based on a functional analytic framework simplifying and generalizing previous works in this direction. In particular our results rely on the novel use of a general but elementary topological observation, valid in any metric space, which concerns the growth of continuous functions in the neighborhood of compact sets. In the case when $\{S(t)\}_{t \geq 0}$ does not possess a compact absorbing set, this lemma allows us to sidestep the use of weak compactness arguments which require the imposition of cumbersome weak continuity conditions and limits the phase space $X$ to the case of a reflexive Banach space. Two examples of concrete dynamical systems where the semigroup is known to be non-compact are examined in detail.

description: Injection locking is a way of sinchronizing one free-running oscillator to a stabilized master oscillator. When considering applications utilizing this technique in semiconductor lasers, the noise properties of the locked lasers are of vital importance. In this paper we present and analyze some clarifying simulation results about determinate aspects related to the effect of noise on injection-locking. In this aim, a new semiconductor injection-locked laser modelling technique that includes this important effect of noise, both from the injected laser and from the external source, has been implemented. This modelling technique is based on a description of the coherent rate equations in terms of a funcional blocks diagram that can be analized by means of a suitable computer simulation program

Inertial waves in a differentially rotating spherical shell

description: We investigate the properties of small-amplitude inertial waves propagating in a differentially rotating incompressible fluid contained in a spherical shell. For cylindrical and shellular rotation profiles and in the inviscid limit, inertial waves obey a second-order partial differential equation of mixed type. Two kinds of inertial modes therefore exist, depending on whether the hyperbolic domain where characteristics propagate covers the whole shell or not. The occurrence of these two kinds of inertial modes is examined, and we show that the range of frequencies at which inertial waves may propagate is broader than with solid-body rotation. Using high-resolution calculations based on a spectral method, we show that, as with solid-body rotation, singular modes with thin shear layers following short-period attractors still exist with differential rotation. They exist even in the case of a full sphere. In the limit of vanishing viscosities, the width of the shear layers seems to weakly depend on the global background shear, showing a scaling in E^{1/3} with the Ekman number E, as in the solid-body rotation case. There also exist modes with thin detached layers of width scaling with E^{1/2} as Ekman boundary layers. The behavior of inertial waves with a corotation resonance within the shell is also considered. For cylindrical rotation, waves get dramatically absorbed at corotation. In contrast, for shellular rotation, waves may cross a critical layer without visible absorption, and such modes can be unstable for small enough Ekman numbers.

Effect of bubble size and sparging frequency on the power transferred onto membranes for fouling control
Creators: name: Jankhah, Sepideh
Publisher: name: University of British Columbia
Year: 2013

description: Fouling control through air sparging in membrane systems is governed by the hydrodynamic conditions in the system and the resulting shear stress induced onto membranes. However, the relationship between hydrodynamic conditions and the extent of fouling control is not well understood. As a result, sparging approaches are designed using a capital and time intensive empirical trial-and-error approach that does not guarantee that optimal conditions are identified. To address this knowledge gap, the present research focused on characterizing the hydrodynamic conditions in a membrane system under different sparging conditions (bubble size and frequency) and on finding a correlation between the induced hydrodynamic conditions and fouling control efficiency. New concepts of zone of influence of bubbles and power transferred were defined to characterise the hydrodynamic conditions in the system. A non-homogenous fouling distribution was observed in the zone of influence of bubbles due to a non-homogenous distribution of velocity and shear stress in this zone. Fouling rates generally decreased with an increase in the area of the zone of influence, the root mean square of shear stress induced onto membranes and the rise velocity of bubbles. However, none of these parameters on their own could accurately describe the effect of the hydrodynamic conditions on fouling rate. On the other hand, power transferred onto fibers, which incorporates the effect of all the three parameters, could more effectively describe the effect of the hydrodynamic conditions on the rate of fouling. Power transfer efficiency into the system, defined as the ratio of power transferred onto membranes to the power input in the system, was used to identify optimal sparging approaches. For all cases investigated, the power transfer efficiency to the system was consistently much higher for pulse bubble than for coarse bubble sparging. The results also indicated that as sparging frequency and the size of the bubbles increased, the width of zone of influence increased, suggesting that the spacing between the spargers could be increased when sparging with larger bubbles or at higher frequencies. Increasing the spacing would not only decrease the number of spargers, but also the volume of the gas required for sparging.
Calculation of intermediate-energy electron-impact ionization of molecular hydrogen and nitrogen using the paraxial approximation

description: We have implemented the paraxial approximation followed by the time-dependent Hartree-Fock method with frozen core for the single impact ionization of atoms and two-atomic molecules. It reduces the original scattering problem to the five-dimensional time-dependent Schrödinger equation solution. By using this method we calculated the multi-fold differential cross section of the impact single ionization of the helium atom, the hydrogen molecule and the nitrogen molecule by the intermediate energy electrons. Our results for the helium and the hydrogen are quite close to experimental data, but for N$_2$ the agreement is worse apparently because of the insufficiency of the frozen core approximation.

description: There has been considerable recent activity with SiGe technology and much speculation that it will soon dis­place GaAs. Advances in conventional CMOS, over the years, have been based around device scaling. As submi-cron dimensions have been approached, further scaling of CMOS becomes increasingly complex and fundamen­tal limits will soon emerge. The significance of SiGe is that it is compatible with conventional silicon process­ing and offers improved material properties, so that con­tinued advancement can be sustained. We examine the present status of SiGe with respect to GaAs.

The answer was a combination of well-coordinated movement, sustained infantry fire over distance and artillery support. Close combat remained only the last – albeit often mystified – phase in a much more sophisticated tactical scheme.

description: Multifunctional properties of semi-insulating GaAs type crystals could be essentially expanded under special boundary conditions. These crystals partial strain limitation makes possible to obtain electrical response on such external scalar influence as hydrodynamic pressure or temperature change. This gives rise to a new generation of microelectronic one-crystal sensors in which transducers, amplifiers and read-out electronics are various parts of the same crystal. In these devices, semi-insulating wafer itself is employed as matrix of sensor elements while amplifiers and other micro-electronics are no more than very thin semiconductor epitaxial layers.

description: Für die elektrochemische Synthese kupferorganischer Verbindungen wurde Malonsäuredintril (MSDN), 1,1,3,3-Tetracyanpropan (TCPH) und Isophthalsäuredinitril (IPDN) verwendet. Als Lösemittel diente Acetonitril, daß zur Erhöhung der Leitfähigkeit mit Tetrabutylammoniumtetrafluoroborat versetzt wurde. Mit cyclovoltammetrischen Untersuchungen an einer stationären Kupfer- und Platinelektrode erfolgte die Bestimmung des Reduktionsverhaltens der Nitrile. Die Elektrosynthese mit MSDN führte zu der zweikernigen CN-verbrückten Kupferverbindung {[Cu2(µ-CN)(CH3CN)3]CH(CN)2}n. Durch die Zugabe von Triphenylphoshan zur Reaktionslösung konnte nach der elektrochemischen Umsetzung {[Cu2(µ-CN)(PPh3)3]CH(CN)2}n erhalten werden. Bei der Elektrosynthese mit TCPH entsteht das Kuprat {(n-C4H9)4N[Cu(TCP)BF4]}n. Wurde auf den Leitelektrolyten (n-C4H9)4NBF4 verzichtet, konnte die Verbindung [(CH3CN)CuTCP]n dargestellt werden. Eine Kupferverbindung mit der Zusammensetzung (Ph3P)3CuC6H4(CN)2 wurde bei der elektrochemischen Umsetzung von IPDN in Gegenwart von Triphenylphosphan erhalten. Die Darstellung der phosphanfreien Substanz war elektrochemisch nicht möglich.
description: Malonic acid dinitrile (MSDN), 1,1,3,3-tetracyanopropane (TCPH) and isophthalonitrile (IPDN) were used for the electrochemical synthesis of copper-organic compounds. The addition tetrabutylammonium tetrafluoroborate to the solvent acetonitrile increased the conductivity. Cyclovoltammetric investigations at a stationary copper and platinium electrode were carried out in order to determine the reduction behaviour of the nitriles. The electrochemical synthesis with MSDN gave the binuclear CN-bridged copper compound {[Cu2(µ-CN)(CH3CN)3]CH(CN)2}n. The electrochemical reaction in the presence of triphenylphosphane resulted in {[Cu2(µ-CN)(PPh3)3]CH(CN)2}n. The product of the electrochemical synthesis with TCPH was the cuprate {(n-C4H9)4N[Cu(TCP)BF4]}n. The compound [(CH3CN)CuTCP]n could be obtained without the conductivity electrolyte (n-C4H9)4NBF4. A copper compound with the composition (Ph3P)3CuC6H4(CN)2 was received by the electrochemical conversion of IPDN in the presence of triphenylphosphane. The electrochemical preparation of the copper compound without the triphenylphosphane ligands was not successful.

description: There may be non-thermal cosmic rays during big-bang nucleosynthesis (BBN) epoch (dubbed as BBNCRs). This paper investigated whether such BBNCRs can be the origin of Lithium problem or not. It can be expected that BBNCRs flux will be small in order to keep the success of standard BBN (SBBN). With favorable assumptions on the BBNCR spectrum between 0.09 -- 4 MeV, our numerical calculation showed that extra contributions from BBNCRs can account for the $^7$Li abundance successfully. However $^6$Li abundance is only lifted an order of magnitude, which is still much lower than the observed value. As the deuteron abundance is very sensitive to the spectrum choice of BBNCRs, the allowed parameter space for the spectrum is strictly constrained. We should emphasize that the acceleration mechanism for BBNCRs in the early universe is still an open question. For example, strong turbulent magnetic field is probably the solution to the problem. Whether such a mechanism can provide the required spectrum deserves further studies.

description: To investigate how $\textit{Campylobacter jejuni}$ causes the clinical symptoms of diarrhoeal disease in humans, use of a relevant animal model is essential. Such a model should mimic the human disease closely in terms of host physiology, incubation period before onset of disease, clinical signs and a comparable outcome of disease. In this study, we used a gnotobiotic piglet model to study determinants of pathogenicity of C. $\textit{C. jejuni}$. In this model, C. $\textit{C. jejuni}$ successfully established infection and piglets developed an increased temperature with watery diarrhoea, which was caused by a leaky epithelium and reduced bile re-absorption in the intestines. Further, we assessed the C. $\textit{C. jejuni}$ genes required for infection of the porcine gastrointestinal tract utilising a transposon (Tn) mutant library screen. A total of 123 genes of which Tn mutants showed attenuated piglet infection were identified. Our screen highlighted a crucial role for motility and chemotaxis, as well as central metabolism. In addition, Tn mutants of 14 genes displayed enhanced piglet infection. This study gives a unique insight into the mechanisms of C. $\textit{C. jejuni}$ disease in terms of host physiology and contributing bacterial factors.

description: Excerpts from the report Summary: The importance to rice growers and others of efficient, low cost drying and storage of rough rice is reflected in the amount spent for these services. Of the $150 million received annually by rough rice growers in Louisiana and Texas, an estimated $15 to $16 million is spent for drying and storing. To accumulate data for determining why some facilities are successful and presumably low cost, while others are not, 51 driers in Louisiana and 44 in Texas were studied during three marketing seasons, 1959/60, 1960/61, 1961/62. The 95 driers were of four types: (1) on-farm round stationary bulk bins, (2) on-farm buildings with bulk bins, (3) on-farm multipass, continuous flow driers, and (4) off-farm or commercial multipass, continuous flow driers. Items compared in evaluating these driers included in-plant operating costs, marketing costs, and effect of drying and storing on rice quality. To facilitate comparisons, all data were expressed on the basis of hundredweights of dry rice, rather than on the basis of barrels of green rice, as is common to the trade.

description: We consider level-set percolation for the Gaussian free field on Z^d, with d bigger or equal to 3, and prove that there is a non-trivial critical level h_* such that for h > h_*, the excursion set above level h does not percolate, and for h < h_*, the excursion set does percolate. It is known from the work of Bricmont-Lebowitz-Maes that h_* is non-negative for all d bigger or equal to 3, and finite, when d=3. We prove here that h_* is finite for all d bigger or equal to 3. In fact, we introduce a second critical parameter h_**, which is bigger or equal to h_*. We show that h_** is finite for all d bigger or equal to 3, and that the connectivity function of the excursion set above level h has stretched exponential decay for all h > h_**. Finally we prove that h_* > 0 in high dimension. It remains open whether h_* and h_** actually coincide, and whether h_* > 0 for all d bigger or equal to 3.

description: The gate burnout (irreversible breakdown) of GaAs MESFET has been studied using two-dimensional (2-D) numerical simulation and experimental measurements of 10 ns pulsed gate-source I-V characteristics. It is shown, that at some critical level of gate avalanche current the gate current instability appears. The instability results in formation of a negative differential conductivity (NDC) region on the S-shape gate-source I-V characteristic, spatial instability of avalanche current and formation of high density current filaments.

description: The banana prawn component of Australia’s Northern Prawn Fishery (NPF) is currently managed through the use of annually updated trigger catch rates as a means of achieving maximum economic yield (MEY) in the fishery, taking into account the estimated price and cost components for that season. The estimation of these target catch rates is based on the assumption of relative homogeneity of the fleet in terms of efficiency, productivity and cost structure. In this study, these assumptions are examined through the estimation of a stochastic production frontier. While technical efficiency varies between vessels, average efficiency is relatively constant over the fishing season. However, average productivity of the fleet increases, with smaller vessels (in terms of engine power) exiting the fishery earlier. This would likely increase the average cost of fishing towards the end of the season, with implications for setting the target catch rate. Based on a standard assumption as to the relationship between costs and vessel size, we find that the MEY target catch rates are most likely currently underestimated. However, the implementation of a precautionary minimum catch rate (which is above the MEY target catch rates for recent years) has maintained the fishery at a profitable level.

description: We report the fabrication and characterization of the InGaP/GaAs single het­erojunction bipolar transistor (SHBT). The cross sectional structure of the studied device is shown in Fig.l. The SHBT with a delta-doped sheet located at the E-B heterointerface (delta-SHBT) exhibits a common-emitter current gain as high as 410 and an extremely low offset voltage of only 55 mV. Figure 2(a) and (b) illustrate the I-V characteristics and the expanded view near the near of the same device. The higher current gain of delta-SHBT can be attributed to the increase of the hole barrier resulting from the delta-doped sheet and to the reduction of charge storage because of the existence of thin spacer (50-A). The low offset voltage is due to the elimination of the potential spike of E-B junction. The calculated conduction band-edge dia­grams near the E-B junction of delta-SHBT, conventional SHBT and HEBT at various biased conditions are plotted in Fig.3. At equilibrium, no potential spike exists for all the three structures. As Vbe= + 1.0 V forward biased, a potential spike about 60 meV existed in an SHBT while no potential spike existed in both delta-SHBT and HEBT. Also notice that the width of neutral region in narrow energy-gap emitter for an HEBT is also increased with biased voltage. It is evident that the potential spike do be eliminated by utilizing delta-doped sheet. On the other hand, calculated increase of the E-B capacitance for our delta-SHBT is very small due to the thin enough delta-doped sheet.

description: We study neutrino spin oscillations in black hole backgrounds. In the case of a charged black hole, the maximum frequency of oscillations is a monotonically increasing function of the charge. For a rotating black hole, the maximum frequency decreases with increasing the angular momentum. In both cases, the frequency of spin oscillations decreases as the distance from the black hole grows. As a phenomenological application of our results, we study simple bipolar neutrino system which is an interesting example of collective neutrino oscillations. We show that the precession frequency of the flavor pendulum as a function of the neutrino number density will be higher for a charged/non-rotating black hole compared with a neutral/rotating black hole respectively.

description: In this paper we report on the hot-electrons in­duced degradation in AlGaAs/GaAs HEMT's and Al-GaAs/InGaAs/GaAs PM-HEMT's, consisting in a de­crease in the drain current. We have found that the amount of the degradation is correlated to to the impact-ionization in the channel, which is related to the electron energy. Creation of traps is the degradation mechanism which has been found to be responsible for the observed Id degradation. Drain current DLTS (Deep Level Tran­sient. Spectroscopy) analyses and transconductance fre­quency dispersion measurements have been used to iden­tify properties and localization of these traps. These techniques appear to be a powerful tool to study the relia­bility problems arising in HEMT structures due to defect created by hot electrons.

description: We show that a baryon asymmetry can be generated by dissipative effects during warm inflation via a supersymmetric two-stage mechanism, where the inflaton is coupled to heavy mediator fields that then decay into light species through B- and CP-violating interactions. In contrast with thermal GUT baryogenesis models, the temperature during inflation is always below the heavy mass threshold, simultaneously suppressing thermal and quantum corrections to the inflaton potential and the production of dangerous GUT relics. This naturally gives a small baryon asymmetry close to the observed value, although parametrically larger values may be diluted after inflation along with any gravitino overabundance. Furthermore, this process yields baryon isocurvature perturbations within the range of future experiments, making this an attractive and testable model of GUT baryogenesis.

description: Self heating in ultrashort gate length GaAs Pseudomorphic High Electron Mobility Transistors (PHEMT) is investigated. The experimental results include an original measurement of the average temperature in the gate drain area of the device channel. An original model which accounts for both bidimensional heat transfer and quasi bidimensional energy balance carrier transport is described. Typical simulations in good agreement with the experiments are discussed.

description: New versions of the set-valued average value at risk for multivariate risks are introduced by generalizing the well-known certainty equivalent representation to the set-valued case. The first "regulator" version is independent from any market model whereas the second version, called the market extension, takes trading opportunities into account. Essential properties of both versions are proven and an algorithmic approach is provided which admits to compute the values of both version over finite probability spaces. Several examples illustrate various features of the theoretical constructions.
