description: Machine learning algorithms offer the promising opportunity to monitor a photovoltaic system’s performance, particularly its power output, using alternative data sources. In this work we consider performance data collected from nearby sites, rather than environmental data acquired with costly sensors or purchased from external sources. This study compares five different machine learning algorithms and their respective prediction accuracy of the output power using as input either power data from nearby systems or environmental data collected from an onsite weather station or one nearby. We show that power data from nearby sites can be used for predictions that are as precise as those based on onsite measured environmental data.

description: The city of Honolulu, Hawaii is currently planning and developing a new rail transit system. While Honolulu has supportive density and topography for rail transit, questions remain about its ability to effectively integrate urban design and accessibility across the system. Every transit trip begins and ends with a walking trip from origins and to destinations: transportation planning must account for pedestrian safety, comfort, and access. Ildefons Cerda's 19th century utopian plan for Barcelona's Eixample district produced a renowned, livable urban form. The Eixample, with its well-integrated rail transit, serves as a model of urban design, land use, transportation planning, and pedestrian-scaled streets working in synergy to produce accessibility. This study discusses the urban form of Honolulu and the history and planning of its new rail transit system. Then it reviews the history of Cerda's plan for the Eixample and discusses its urban form and performance today. Finally it draws several lessons from Barcelona's urban design, accessibility, and rail transit planning and critically discusses their applicability to policy and design in Honolulu. This discussion is situated within wider debates around livable cities and social justice as it contributes several form and design lessons to the livability and accessibility literature while identifying potential concerns with privatization and displacement.

description: SolarFarmer is a new photovoltaic (PV) plant design and performance modelling software, developed by DNV GL [1]. Now that SolarFarmer is available to the PV community, we are publishing validation results, using operational data of commercial PV plants. So far, validation has been carried out for 6 sites of which 2 were excluded because there was insufficient site data. Good agreement has been found between actual and modelled production, with mean bias errors (MBE) of 0.4 % and root mean squared errors (RMSE) 13.1 % average for the 4 remaining sites. SolarFarmer validation continues as data from more PV plants become available or changes are made in the software and results will be published on regular basis.
The Impact Of Transportation In Logistics Performance: The Case Of Major General Haylom Araya Military Academy
Creators: name: Mersha, Yalew
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The purpose of this study was to examine the role of transportation in logistics performance. Effective logistics management has different core functions in military activities, these are: deployment and distribution, supply, maintenance, operational contract support (OCS), engineering, and health services (HS). By considering this fact and central role of transportation at every military logistics activity, the researcher performed the study by identifying roles of transportation in logistics performance dimensions (logistics differentiation, effectiveness and efficiency); and to see the relationship between transportation and logistics performance. Explanatory research design was employed with mixed method. A total of 114 questionnaires were distributed to respondents; 104 were returned and refined for analysis. Interview questions were prepared for logistic sub unit head, transport heads, warehouse keepers, and purchasing and supply head of the military academy. The role of transportation was analyzed using descriptive statistics like mean and standard deviation. As per the result weakness observed in areas of service cost efficiency, the overall quality of transportation, transportation cost and some human and non human factors affecting performance of transportation is identified. The relationships proposed in the framework were tested using Pearson correlation, and the causal relations were analyzed using regression analysis. From the result of the analysis, it is concluded that there is strong causal relationship between role of transportation and logistics performance. From the finding, it was recommended that, increase transportation performance (by providing safe and secure movement of personals and materials, fast travel time and finical/economical management) is better for the military academy to improve the logistics performance. Because most of logistics function is transportation dependent

description: We employ dispersion-corrected density-functional theory to study the adsorption of tetrapyrrole 2H-porphine (2H-P) at Cu(111) and Ag(111). Various contributions to adsorbate-substrate and adsorbate-adsorbate interactions are systematically extracted to analyze the self-assembly behavior of this basic building block to porphyrin-based metal-organic nanostructures. This analysis reveals a surprising importance of substrate-mediated van der Waals interactions between 2H-P molecules, in contrast to negligible direct dispersive interactions. The resulting net repulsive interactions rationalize the experimentally observed tendency for single molecule adsorption.

description: When sizing the components of renewable energy systems to be able to cover the load with a certain security of supply the selection of the data meant to represent the meteorological conditions governing the systems performance plays a decisive role. Current approaches comprise either to select or construct years assumed to present typical statistical properties or years assumed to present the most challenging conditions in view to assure a high degree of load coverage by the renewables up to a 100%. When aiming at systems approaching the complete load coverage by renewables it is obvious that long-term data sets must be considered to identify those condition. Here, a long-term data set is applied to examine the lay-out of a PV system assisting the electricity system of the Faroe Islands. For this example, the identification ot the most chalanging conditions in a 56-years set and the conseqences of the use of incomplete sets in view of the occurence of deficit situations is discussed.
Assessments of procurement spending analysis. A case study in Dashen Bank, Ethiopia
Creators: name: Taddese, Zelalem
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The lack of effective procurement spending analysis is often considered as a corporate epidemic that is keeping businesses from controlling costs and improve performance from their current mammoth procurement spend. Insufficient visibility and analysis of corporate spending information limit businesses ability to understand spending patterns, maximize buying leverage, execute informed sourcing and supply management decisions. Whereas effective spend analysis drive continuous improvement in contract compliance and supplier performance, optimize budgeting and planning, and the impact of change in cost and inflation. Dashen bank as a growing and expanding bank has deployed critical and often exorbitant information technology infrastructure, under take several own building construction and procure products and services, whereas the banks procurement appetite, variety, and complexity are continuously increasing and on the other hand the lead time for procurement is shortening. As the result, the understandings of procurement spend analysis and its effectiveness has vital importance and deserves close investigation. The study adopts a descriptive research method as it is more appropriate to portray a more accurate profile of practices, process or operations in relation to spend analysis in particular reference to Dashen Bank. As a case study, the research also involves an empirical investigation of the contemporary phenomenon within its real life context and provides a rich understanding of the context of the research. The data for the study was collected from 31 employees of Dashen Bank using structured questionnaire and structured interview from selected key staff. The questionnaire data were analysed using descriptive statistics and data from interview and document reviews were interpreted qualitatively. Therefore, in order to realize effective procurement spend analysis, there is compelling reasons for Dashen to develop new spend analysis programme and implement relevant tools, processes, enhancing competency of procurement spend analysis in order to achieving full spend visibility

description: Financial profitability analysis is a substantial preliminary study topic and a key decision criterion when designing and building a PV system. In this context, energy storage has increased the capability for maximizing the energy self-consumption and the profitability of PV systems, but it has also complexified the optimization strategies. Battery storage in a PV system allows to displace the usage of the solar generated power to times where consumption is needed. However, the sizing of the optimal system depends on many factors, such as meteorological data, load profile, battery size and price, feed-in tariffs, etc. PVsyst is a simulation software used to model PV systems, from small residential size up to large utilities. The new economic evaluation tool included in the software allows to perform a detailed analysis, producing key financial indicators such as the Levelized Cost of Energy (LCOE), payback time and return on investment (ROI). The aim of this study is to establish a methodology for the optimization of PV systems with self-consumption and storage. The optimization of several economic variables, based on parametric simulations, will be presented. We will also show a simple way to estimate the optimal sizing using the results of a single simulation.

description: The DC/AC ratio is a key design parameter of solar PV plants. In recent years, the cost reduction in PV modules has led to increased DC/AC ratios. Our experience shows that such designs are often mis-optimised because the impacts of sub-hourly irradiation fluctuations and PV module degradation are not adequately accounted for using standard industry software. Seven sites located in tropical and temperate climate have been analysed, along with an eighth control project located in a desertic climate where minimal cloud cover is present. To estimate the DC side inverter clipping losses of each system, hourly and sub-hourly (10min and 5min) yield modelling of a standardized 1MWAC system was performed in PVsyst, varying the DC/AC ratio from 1.2 to 1.7. The clipping loss was calculated over the 25-year life of the plant taking the module degradation into consideration, and the LCOE for each site and system configuration was found based on simplified CAPEX and OPEX assumptions. The analysis performed shows that yield modelling on an hourly basis, underestimates the DC side inverter clipping of systems in tropical and temperate climates where moderate to high variation in cloud cover occurs. Systems optimised on sub-hourly basis may therefore result in lower installed DC capacity, in the range of 2-6%, thus an overall lower CAPEX, and higher financial returns for developers.

description: We present a detailed analysis of the kinematics of the Galactic globular cluster NGC 6397 based on more than ~18,000 spectra obtained with the novel integral field spectrograph MUSE. While NGC 6397 is often considered a core collapse cluster, our analysis suggests a flattening of the surface brightness profile at the smallest radii. Although it is among the nearest globular clusters, the low velocity dispersion of NGC 6397 of <5km/s imposes heavy demands on the quality of the kinematical data. We show that despite its limited spectral resolution, MUSE reaches an accuracy of 1km/s in the analysis of stellar spectra. We find slight evidence for a rotational component in the cluster and the velocity dispersion profile that we obtain shows a mild central cusp. To investigate the nature of this feature, we calculate spherical Jeans models and compare these models to our kinematical data. This comparison shows that if a constant mass-to-light ratio is assumed, the addition of an intermediate-mass black hole with a mass of 600M_sun brings the model predictions into agreement with our data, and therefore could be at the origin of the velocity dispersion profile. We further investigate cases with varying mass-to-light ratios and find that a compact dark stellar component can also explain our observations. However, such a component would closely resemble the black hole from the constant mass-to-light ratio models as this component must be confined to the central ~5arcsec of the cluster and must have a similar mass. Independent constraints on the distribution of stellar remnants in the cluster or kinematic measurements at the highest possible spatial resolution should be able to distinguish the two alternatives.

description: Silicon and Germanium monopnictides SiP, SiAs, GeP and GeAs form a family of 2D layered semiconductors. We have succeeded in growing bulk single crystals of these compounds by melt-growth under high pressure (0.5-1 GPa) in a cubic anvil hot press. Large (mm-size), shiny, micaceous crystals of GeP, GeAs and SiAs were obtained, and could be exfoliated into 2D flakes. Small and brittle crystals of SiP were yielded by this method. High-pressure sintered polycrystalline SiP and GeAs have also been successfully used as a precursor in the Chemical Vapor Transport growth of these crystals in the presence of I$_{2}$ as a transport agent. All compounds are found to crystallize in the expected layered structure and do not undergo any structural transition at low temperature, as shown by Raman spectroscopy down to T=5K. All materials exhibit a semiconducting behavior. The electrical resistivity of GeP, GeAs and SiAs is found to depend on temperature following a 2D-Variable Range Hopping conduction mechanism. The availability of bulk crystals of these compounds opens new perspectives in the field of 2D semiconducting materials for device applications.

description: The present work aims to gather, analyze and organize the information available in the literature about failure modes and failure rates in photovoltaic systems, mapping their origins and conditions under which they were obtained to provide unambiguous and trustworthy information for reliability studies on general PV systems. A set of guiding questions have been listed to clearly detail the original context of each publication. Filtering the references with failure information based on field data, the most common failures registered in PV systems were identified. With this information, a list has been created containing the failure rates for the major components in the PV system: transformer, inverter, and PV array. In particular, the failures in the PV module are detailed further according to its internal components and failure modes. This information can be used in reliability studies regarding the general behavior of a PV system.

description: Thermal Infrared (TIR) imaging is one of the techniques frequently used to inspect underperforming modules in Photovoltaic (PV) plants. TIR imaging of operational PV modules is generally misinterpreted because of the dynamic nature of some types of soiling and the dynamic nature of the current-voltage (I-V) operating point of the string, modules, substrings (bypass diode) and thus individual cells. If one substring is sufficiently mismatched causing the bypass diode to lower the current in that substring, then TIR imaging of damaged cells in the substring would be inhibited. Additionally, cells causing equally mismatched substrings inhibit the TIR imaging of damaged cells. The damaged cells operated at a voltage that causes the TIR image to have no abnormal signature and also affected the maximum power point (MPP) of the module. TIR imaging conducted on unsoiled modules can locate damaged cells and facilitate decision making during PV module inspections. Incorporation of other inspection techniques, such as power measurements and EL imaging, add valuable information regarding the state of the PV modules.

description: As with many women in early cinema, such as Jeanie Macpherson and Frances Marion, Dorothy Farnum’s career in Hollywood began with acting before settling into writing. Known for her intelligence and beauty, she worked well in front of the camera. From articles in the Los Angeles Times, we know that she was educated in a convent boarding school (location unknown) where Farnum mastered French history and literature and became fluent in Spanish and German (C27, 33). Although she received several offers to act and even appeared in the films Over Night (1915) and The Cub (1915), she was reported to have instead preferred writing scenarios for the silent screen. Farnum’s scenario writing career began in 1919 when she approached producer Harry Rapf with an original scenario titled The Broken Melody. Impressed with her skills, he employed Farnum at a commission of twenty-five dollars a week. Unfortunately, after just two weeks Farnum proved to be too inexperienced and was released from her contract. Rapf promised to employ her once she attained a footing in the industry and refined her trade. Farnum continued to work for a few years, steadily writing adaptations and scenarios. Finally, as reported in the Los Angeles Times, Rapf rehired her in May 1926 and gave her work on what would become one of her most renowned films: Beau Brummel (1924) starring John Barrymore (C27).

description: Photovoltaic I-V curve contains rich information about the status of the PV module or array. Therefore, the I-V curve-based PV diagnosis has always been a popular issue, especially with the solutions of the I-V curve measurement at module or array level becoming commercially-available in recent years. Among the I-V curve-based diagnosis applications, the correction of I-V curves measured under various environmental condition to an identical condition is usually a crucial step. However, there is no specific method dedicated to the correction of faulty I-V curves. Therefore, the correction procedures proposed in IEC 60891 standard are commonly adopted, which, however, have only been validated for the correction of curves measured for healthy PV module or array. Consequently, this paper is conceived to evaluate the performance of the IEC 60891 single curve-based methods (procedure 1 and 2) for the correction of faulty I-V curves. Five types of fault conditions of a PV array are addressed. The correction methods are tested using three groups of I-V curves simulated difference irradiance and module temperature. Their impact on the correction performance are specially analyzed. Suggestions for the selection of procedure 1 or 2 under different conditions are given at the end.

description: Aerial infrared thermography (aIRT) has already proven to be a fast and effective method for detecting and classifying faults in photovoltaic (PV) systems. This paper aims at summarizing the key findings of a flight campaign carried out in Brazil over three multicrystalline silicon PV power plants. It reports common defects found in the various plants showing UAV-captured image data and correlation between visible and IR sensors. The most common defect detected were disconnected substrings, indicating module fabrication defects. The second most common fault was disconnected strings, followed by modules with broken front glass and other types of hot-spots. The results indicate the need for a more detailed quality analysis of the PV modules that are being installed at power plants in Brazil, and also demonstrate the viability of using aIRT as a method for inspection and monitoring of PV power plants.

description: Elucidating whether PTSD symptoms predict poorer social connectedness over time (i.e. social erosion) and/or that poor social connectedness contributes to maintenance of PTSD (i.e. social causation) has implications for PTSD treatment and relapse prevention. Most extant research has been cross-sectional and examined overall PTSD symptoms. Evidence of longitudinal associations among heterogeneous PTSD symptom clusters and social connectedness could provide insight into more nuanced targets for intervention. Using data from 1,491 U.S. military veterans in residential treatment for PTSD at 35 Department of Veterans Affairs facilities, we evaluated a two-wave cross-lagged panel model including a five-factor model of PTSD and two aspects of social connectedness. PTSD, quality of connectedness (i.e. degree of distress related to interpersonal conflict), and structural social support (i.e. number of days of contact with supportive loved ones) in the past 30 days were assessed at baseline and 4 months after discharge. The largest effect was greater severity of PTSD dysphoric arousal symptoms (i.e. irritability/anger, poor concentration, and sleep problems) at baseline predicting more conflict-related distress at follow-up (β = 0.43). Post-hoc symptom-level analyses indicated that irritability/anger drove this association. In addition, conflict-related distress predicted greater PTSD symptom severity across all five clusters (β’s = 0.10 to 0.14, p’s < 0.01). More days of contact predicted lower severity of avoidance and numbing symptoms (β’s = −.05 and −.07, p’s < 0.01), along with individual symptoms within these clusters, plus flashbacks. Results support both social erosion and social causation models. Engaging loved ones in veterans’ treatment and targeting dysphoric arousal symptoms, particularly anger and irritability, may improve long-term PTSD and relationship outcomes, respectively. • Sample: 1,491 military veterans in residential treatment for PTSD.• Examined 5-factor model of PTSD and social connectedness measured twitreatment baseline and 4 months after discharge.• Baseline dysphoric arousal (anger, sleep problems, poor concentration) predicted distress related to interpersonal conflict; anger drove this association.• Conflict-related distress at baseline predicted symptoms in all clusters at follow-up.• More days of contact with supportive loved ones at baseline predicted less avoidance and numbing.

description: A Compton gamma imager has been developed for use in consequence management operations and in security investigations. The imager uses solid inorganic scintillator, known for robust performance in field survey conditions. The design was constrained in overall size by the requirement that it be person transportable and operable from a variety of platforms. In order to introduce minimal dead material in the path of the incoming and scattered gamma rays, custom silicon photomultipliers (SiPMs), with a thin glass substrate, were used to collect the scintillation light from the scatter layers. To move them out of the path of the gamma rays, preamplification electronics for the silicon photomultipliers were located a distance from the imager. This imager, the Silicon photomultiplier Compton Telescope for Safety and Security (SCoTSS) is able to provide a one-degree image resolution in a plus-minus 45 degree field of view for a 10 mCi point source 40 m distant, within about one minute, for gamma-ray energies ranging from 344 keV to 1274 keV. Here, we present a comprehensive performance study of the SCoTSS imager.

description: Automatic failure detection and diagnosis (FDD) is a key tool for the application of predictive maintenance. The use of fault data synthesized with simulation models is an alternative solution to circumvent the difficulty of data for training machine learning FDD algorithms.

The resulting algorithms were tested with experimental data to identify the most consistent and best performing FCNN architecture, which achieved a true positive rate (TPR) above 50% for partial shading and above 90% for all other conditions. The tested technique proved to be suitable for the detection of mild failures such as cell short-circuit. However, its performance consistency depends on the hyperparameters, which should be selected by testing with real data. Moreover, achieving high TPR values depend on clear distinction between the failures’ signatures. A synthetic dataset of failures is a powerful resource to study the overlap of signatures to develop automatic FDD algorithms.

description: Results of the time variability monitoring of the two classical T Tauri stars, RU Lup and IM Lup, are presented. Three photometric data sets were utilised: (1) simultaneous (same field) MOST satellite observations over four weeks in each of the years 2012 and 2013, (2) multicolour observations at the SAAO in April - May of 2013, (3) archival V-filter ASAS data for nine seasons, 2001 - 2009. They were augmented by an analysis of high-resolution, public-domain VLT-UT2 UVES spectra from the years 2000 to 2012. From the MOST observations, we infer that irregular light variations of RU Lup are caused by stochastic variability of hot spots induced by unstable accretion. In contrast, the MOST light curves of IM Lup are fairly regular and modulated with a period of about 7.19 - 7.58 d, which is in accord with ASAS observations showing a well defined 7.247+/-0.026 d periodicity. We propose that this is the rotational period of IM Lup and is due to the changing visibility of two antipodal hot spots created near the stellar magnetic poles during the stable process of accretion. Re-analysis of RU Lup high-resolution spectra with the Broadening Function approach reveals signs of a large polar cold spot, which is fairly stable over 13 years. As the star rotates, the spot-induced depression of intensity in the Broadening Function profiles changes cyclically with period 3.71058 d, which was previously found by the spectral cross-correlation method.

title: UK corporate bribery and corruption: an enforcement paradox
Creators: name: Mills, Nicholas Ford
Publisher: name: University of Reading
Year: 2023

description: This thesis explores the UK’s approach to corporate bribery (and other economic crime) enforcement and the tools it uses to do so. When the Bribery Act 2010 (UKBA) came into force, its section 7 (s.7) offence imposed criminal liability for a corporate failing to prevent bribery. However, as well as a defence permeated by accommodative intentions and self�regulatory capacities, this form of criminality is increasingly enforced in characteristically regulatory/non-criminal ways via methods favouring non-prosecution, settlement and negotiation - in the form of Deferred Prosecution Agreements (DPA). Through a noticeable shift in regulatory and enforcement culture, the resulting inquiry is whether the landscape reflects a ‘failure to prevent’ or more a failure to prosecute. The research seeks to inform literature by proposing how the proclaimed prosecutorial stance of enforcement policy has been redefined and weakened by an inability to do so and replaced with cooperative methods that are too heavily reliant on corporate assistance and bargain and bluff tactics. Using a qualitative approach, the work offers views from practitioners in the field to help enlighten and understand the aetiology of current enforcement practices for corporate offending. Through an analysis the results illustrate that due to complexities in corporate criminal liability, changes in the approach to prosecutorial enforcement, limited adherence to enforcement rhetoric and policy, self-regulatory reliance, and a growing favourability for DPAs, the UKBA and correlative intent to impart an enforced self-regulatory culture is presently lacking clarity in the legal objective – redefining the symbolic application of the criminal law. The work proposes that the control of corporate bribery has therefore become paradoxical: actively promulgating investigation and enforcement, but in reality, succumbing to more amenable tendencies of reliance and settlement. Alongside concerns that point to enforcement inability, illogicality, and inequality - that are not indicated by legislative, policy and publicised intent - these have collectively and negatively impacted the enforcement regime. This research enhances the understanding of enforced self-regulatory practices used in corporate crime control and, drawing on responsive regulatory theory, offers important considerations and implications for policy and social scientific development. If serious corporate crime is to be treated as a serious criminal offence, this work reinforces the appropriate use of escalatory enforcement and prosecution - and not its habitual avoidance.
Non-Equilibrium Thermodynamics and Stochasticity, A Phenomenological Look on Jarzynki's Equality

description: The theory of phenomenological Non-equilibrium Thermodynamics is extended by includimg stochastic processes in order to account for recently derived thermodynamical relations such as the Jarzynski equality. Four phenomenological axioms are postulated resulting in a phenomenological interpretation of Jarzynski's equality. Especially, considering the class of Jarzynski processes Jarzynski's equality follows from the axiom that the statistical average of the exponential work is protocol independent.

description: Lyman-$α$ nebulae are usually found in massive environments at high redshift ($z > 2$). The origin of their Lyman-$α$ (Lya) emission remains debated. Recent polarimetric observations showed that at least some Lya sources are polarized. This is often interpreted as a proof that the photons are centrally produced, and opposed to the scenario in which the Lya emission is the cooling radiation emitted by gas heated during the accretion onto the halo. We suggest that this scenario is not incompatible with the polarimetric observations. In order to test this idea, we post-process a radiative hydrodynamics simulation of a blob with the MCLya Monte Carlo transfer code. We compute radial profiles for the surface brightness and the degree of polarization and compare them to existing observations. We find that both are consistent with a significant contribution of the extragalactic gas to the Lya emission. Most of the photons are centrally emitted and scattered inside the filament afterwards, producing the observed high level of polarization. We argue that the contribution of the extragalactic gas to the Lya emission does not prevent polarization to arise. On the contrary, we find that pure galactic emission causes the polarization profile to be too steep to be consistent with observations.

description: This paper presents a generalized integrated framework of semi-automatic surgical template design. Several algorithms were implemented including the mesh segmentation, offset surface generation, collision detection, ruled surface generation, etc., and a special software named TemDesigner was developed. With a simple user interface, a customized template can be semi- automatically designed according to the preoperative plan. Firstly, mesh segmentation with signed scalar of vertex is utilized to partition the inner surface from the input surface mesh based on the indicated point loop. Then, the offset surface of the inner surface is obtained through contouring the distance field of the inner surface, and segmented to generate the outer surface. Ruled surface is employed to connect inner and outer surfaces. Finally, drilling tubes are generated according to the preoperative plan through collision detection and merging. It has been applied to the template design for various kinds of surgeries, including oral implantology, cervical pedicle screw insertion, iliosacral screw insertion and osteotomy, demonstrating the efficiency, functionality and generality of our method.

description: In this work, we present a comparison of Performance Loss Rate calculation methodologies based on originally 8,367 PV system datasets, primarily installed in central Europe. The system data are summarized in the Pearl PV database. Pearl PV is a European COST action aiming at improving the energy performance and reliability of PV systems. The datasets consist of only power measurements. Significant dataset filtering was necessary to remove short time series as well as outliers and resulted in the exclusion of over 90% of the datasets. Three different PLR calculation methodologies have been tested, namely statistical clear-sky fitting, the Year-on-Year approach and seasonal and trend decomposition. Depending on the chosen approach, average system performance losses between -0.75%/a and -1.1%/a have been recorded.
