description: We report on an effort to extract and monitor interstellar scintillation parameters in regular timing observations collected for the NANOGrav pulsar timing array. Scattering delays are measured by creating dynamic spectra for each pulsar and observing epoch of wide-band observations centered near 1500 MHz and carried out at the Green Bank Telescope and the Arecibo Observatory. The ~800-MHz wide frequency bands imply dramatic changes in scintillation bandwidth across the bandpass, and a stretching routine has been included to account for this scaling. For most of the 10 pulsars for which the scaling has been measured, the bandwidths scale with frequency less steeply than expected for a Kolmogorov medium. We find estimated scattering delay values that vary with time by up to an order of magnitude. The mean measured scattering delays are similar to previously published values and slightly higher than predicted by interstellar medium models. We investigate the possibility of increasing the timing precision by mitigating timing errors introduced by the scattering delays. For most of the pulsars, the uncertainty in the time of arrival of a single timing point is much larger than the maximum variation of the scattering delay, suggesting that diffractive scintillation remains only a negligible part of their noise budget.

description: We have developed a novel technique for detection of spin polarization with a quantum dot weakly coupled to the objective device. The disturbance to the object in this technique is very small since the detection is performed through sampling of single electrons in the object with very slow rate. We have applied the method to a quantum point contact (QPC) under a spin-orbit interaction. A high degree of spin polarization in the vicinity of the QPC was detected when the conductance stayed on a plateau at a half of the unit conductance quantum ($G_{\rm q}/2\equiv e^2/h$), and also on another plateau at $2e^2/h$. On the half-quantum plateau, the degree of polarization $P$ decreased with the bias source-drain voltage of the QPC while $P$ increased on the single-quantum plateau, manifesting that different mechanisms of polarization were working on these plateaus. Very long spin relaxation times in the detector quantum dot probably due to dynamical nuclear spin polarization were observed. Anomalous decrease of $P$ around zero-bias was observed at a Kondo-like resonance peak.

description: We have given a summary on our theoretical predictions of three kinds of topological semimetals (TSMs), namely, Dirac semimetal (DSM), Weyl semimetal (WSM) and Node-Line Semimetal (NLSM). TSMs are new states of quantum matters, which are different with topological insulators. They are characterized by the topological stability of Fermi surface, whether it encloses band crossing point, i.e., Dirac cone like energy node, or not. They are distinguished from each other by the degeneracy and momentum space distribution of the nodal points. To realize these intriguing topological quantum states is quite challenging and crucial to both fundamental science and future application. In 2012 and 2013, Na$_3$Bi and Cd$_3$As$_2$ were theoretically predicted to be DSM, respectively. Their experimental verifications in 2014 have ignited the hot and intensive studies on TSMs. The following theoretical prediction of nonmagnetic WSM in TaAs family stimulated a second wave and many experimental works have come out in this year. In 2014, a kind of three dimensional crystal of carbon has been proposed to be NLSM due to negligible spin-orbit coupling and coexistence of time-reversal and inversion symmetry. Though the final experimental confirmation of NLSM is still missing, there have been several theoretical proposals, including Cu$_3$PdN from us. In the final part, we have summarized the whole family of TSMs and their relationship.

description: Over the last 20 years, the statistical average performance ratio of a new photovoltaic (PV) installation
in moderate climates has improved from 0.65 to approximately 0.85. This continuous improvement in the field would
not have been possible without operational monitoring and the continued analysis of monitoring data by the PV
system community. The paper starts with a historical review of the performance of PV systems. It documents the
current state of the art and good practices in PV system monitoring. Finally, it presents periodic linear regression as a
simple though systematic approach for the visual and mathematical analysis of monitoring data.

description: Clouds are the dominant source of spatial and temporal variability of solar radiation that is the main
cause of fluctuating photovoltaic power feed into the grid. Hourly solar radiation measurements are no longer
sufficient to predict the output power of PV generators and to properly analyze the effects of non-homogeneous
irradiance conditions on their performance. There is need of precise information of the instantaneous irradiance
conditions affecting to the generators and faster sampling frequencies are required. In this paper, we present a method
to generate a spatial irradiance map from an array of solar radiation measurements during shading events caused by
moving clouds by analyzing their speed and direction of movement. Furthermore, the irradiance map is validated
with measurements from TUT solar PV power station research plant and compared to the map obtained by applying
natural neighbor interpolation of the instantaneous irradiance measurements directly.

description: Virtual Reality (VR) is becoming popular in multiple applications like gaming, driving, aviation and medical training, fashion and tourism. This study is focused on the promising and encouraging role of Virtual Reality (VR) in engineering programmes. Robust development and innovations have been accelerated in several manufacturing technologies, especially in laser processing, additive manufacturing, and printed electronics. These developments demonstrate the use of Industry 4.0 technologies in creating fully automated and smart manufacturing of products controlled and monitored by computers and robotics. To understand and develop such systems, engineering students need to be trained and prepared for the next generation of computerised machinery, which might not be available in every educational enterprise. Due to its unique ability to produce parts with complex geometry, additive manufacturing (AM) is suitable for manufacturing customised individual products in the biomedical and Aerospace industries. Flexible designs can be adopted, and reduced mass and materials savings can be achieved in addition to processing materials difficult to machines, such as titanium, nitinol and magnesium alloys. Nevertheless, AM is not a standard manufacturing technology in the training of engineering students due to the high initial cost, high running skills and access difficulty due to health and safety regulations. This study reports the employment of a VR lab, tackling this problem and providing the students with a VR-based AM lab in which they can experience the entire build process and carry out assignments efficiently and, most importantly, safely.

description: For the determination of the energy yield of Photovoltaic(PV) systems, meteorological data as well as
technical properties of the PV power plant under consideration are required. Based on these information, the electric
output may be calculated by accounting for the plane-of-array irradiation, the nominal capacity and the Performance
Ratio (PR) of the PV system considered.
In order to determine the PR, Solar Engineering Decker & Mack GmbH developed the first version of their in-house
program named PR-FACT in 2006. Since that time, continuous further development to account for new system
designs and to improve accuracy took place – resulting to version 5 today – while more than 300 projects with a
cumulative capacity of approximately 3,000 MWp have been reviewed worldwide.
PR-FACT divides the Performance Ratio in several single correction factors to account for various parameters
determining the performance or the electric yield, respectively. The program is based on well-established models and
uses technical properties of the PV system as wells as its components provided with the PV power plant design and
the product documentation / data sheets of the manufacturers (e.g. voltage dependent conversion efficiency of the
inverter). The standard version of PR-FACT, for Energy Yield Assessments, works with hourly, meteorological time
series – higher temporal resolution is applicable and applied for e.g. Direct Consumption Studies.
The paper on hand presents models and approaches used within PR-FACT and illustrates results from validation.

description: The present paper containing the studies on the behavior of a typical 10 MWp commercial grid
integrated photovoltaic (GiPV) power plant in India operating successfully for more than one year. It is one of the
plants in the proposed 500 MWp capacity of Gujarat Solar Park in India. The plant was commissioned at the end of
2011 and commercial operation begins at the beginning of 2012. After proper inversion of the generated DC power, it
is exporting into the 66 kV transmission line of Gujarat Energy Transmission Corporation (GETCO) through
appropriate grid integrating systems. Studies for last one year indicated that the plant performance is the function of
some of the sensitive parameters like; i. Incoming solar radiation (Insolation), ii. Ambient temperature profile, iii.
Soling density factor iv. Operating window configuration profile of the inversion systems and v. Setting up of
appropriate operating hours in the inverting systems. Further more an appreciable improvement in power production
was achieved by taking steps on reduction in soiling density factor, lowering of temperature impact, improvement in
generation index, improvement of inversion efficiency, and improvement in power evacuation factor with the
adoption of proper plant management methodologies.
Implementation of all these aspects makes further gain in generation from 2-2.5% more than the targeted generation
figure. The above aspects were analyzed critically and methodologies in further improvement in power production are
presented in the following sections of the paper.

description: We report the large linear magnetoresistance ($\sim 300\%$ in 9 T field at 2 K) and magnetothermopower in layered SrZnSb$_2$ crystal with quasi-two-dimensional Sb layers. A crossover from the semiclassical parabolic field dependent magnetoresistance to linear field dependent magnetoresistance with increasing magnetic field is observed. The magnetoresistance behavior can be described very well by combining the semiclassical cyclotron contribution and the quantum limit magnetoresistance. Magnetic field also enhances the thermopower. Our results can be well understood by the magnetotransport of Dirac states in the bulk band structure.

description: The escape dynamics in an analytical gravitational model which describes the motion of stars in a binary system of interacting dwarf spheroidal galaxies is investigated in detail. We conduct a numerical analysis distinguishing between regular and chaotic orbits as well as between trapped and escaping orbits, considering only unbounded motion for several energy levels. In order to distinguish safely and with certainty between ordered and chaotic motion, we apply the Smaller ALingment Index (SALI) method. It is of particular interest to locate the escape basins through the openings around the collinear Lagrangian points $L_1$ and $L_2$ and relate them with the corresponding spatial distribution of the escape times of the orbits. Our exploration takes place both in the configuration $(x,y)$ and in the phase $(x,\dot{x})$ space in order to elucidate the escape process as well as the overall orbital properties of the galactic system. Our numerical analysis reveals the strong dependence of the properties of the considered escape basins with the total orbital energy, with a remarkable presence of fractal basin boundaries along all the escape regimes. It was also observed, that for energy levels close to the critical escape energy the escape rates of orbits are large, while for much higher values of energy most of the orbits have low escape periods or they escape immediately to infinity. We hope our outcomes to be useful for a further understanding of the escape mechanism in binary galaxy models.

description: The megawatt scale solar is spreading rapidly also in Japan because the FiT system was begun in 2012.
The PV power system has some faults. One might be high the initial investment and it is difficult secondarily to find
the failure PV module by using the measured output characteristic. Therefore, the larger the scale of the photovoltaic
power system is, the more regularly diagnosing it is important. The entrepreneur enables to prevent the sales income
of electricity being decreased beforehand. However, the maintenance check is actually done by stopping the PV
system on a fine day, and using a human labor. The sales income of electricity decrease at the time that stopped for
that, and cost of the maintenance check is expensive. Then, authors proposed a new system. This system assumes the
measurement at time zone in the evening or in the morning under weak irradiance, and does the output characteristic
of the PV module string regularly and automatically. The decrease of accumulated amount is intended to be
suppressed to the minimum by simplifying of the maintenance check work and improving the system availability. In
this study, the proposed system considered the accuracy, how appreciable of the deterioration module.

description: Fourier ptychographic microscopy (FPM) is a novel computational coherent imaging technique for high space-bandwidth product imaging. Mathematically, Fourier ptychographic (FP) reconstruction can be implemented as a phase retrieval optimization process, in which we only obtain low resolution intensity images corresponding to the sub-bands of the sample's high resolution (HR) spatial spectrum, and aim to retrieve the complex HR spectrum. In real setups, the measurements always suffer from various degenerations such as Gaussian noise, Poisson noise, speckle noise and pupil location error, which would largely degrade the reconstruction. To efficiently address these degenerations, we propose a novel FP reconstruction method under a gradient descent optimization framework in this paper. The technique utilizes Poisson maximum likelihood for better signal modeling, and truncated Wirtinger gradient for error removal. Results on both simulated data and real data captured using our laser FPM setup show that the proposed method outperforms other state-of-the-art algorithms. Also, we have released our source code for non-commercial use.

the Joint Research Centre site in Ispra (Italy, European Solar Test Installation laboratories) and the site of Brookhaven
National Laboratories in Upton (NY – USA). The key parameter is the sky clearness index kT, a dimensionless ratio of
the global horizontal irradiance. In the first part, a taxonomical description using daily values of kT is presented, giving
a general overview of the sky conditions during the year. In the second part the analysis is performed using short-term
averages of the clearness index; remarkable properties of the statistical functions are highlighted and reinforced by
using a fuzzy logic method, to extract time independent and site independent subsets. In the third part, a statistical
analysis of the clouds intercepting the Sun’s trajectory is given, and finally, in the fourth part, some time-dependent
correlations between the irradiance and other meteorological variables are studied.

description: Optical spectropolarimetry carried out by Kishimoto et al. (2004) has shown that several luminous type 1 quasars show a strong decrease of the polarized continuum flux in the rest-frame near-UV wavelengths of $λ<4000$Å. In the literature, this spectral feature is interpreted as evidence of the broadened hydrogen Balmer absorption edge imprinted in the accretion disk thermal emission due to the disk atmospheric opacity effect. On the other hand, the quasar flux variability studies have shown that the variable continuum component in UV-optical spectra of quasars, which is considered to be a good indicator of the intrinsic spectral shape of the accretion disk emission, generally have significantly flat spectral shape throughout the near-UV to optical spectral range. To examine whether the disk continuum spectral shapes revealed as the polarized flux and as the variable component spectra are consistent with each other, we carry out multi-band photometric monitoring observations for a sample of four polarization-decreasing quasars of Kishimoto et al. (2004) (4C09.72, 3C323.1, Ton 202, and B2 1208+32) to derive the variable component spectra and compare the spectral shape of them with that of the polarized flux spectra. Contrary to expectation, we confirm that the two spectral components of these quasars have totally different spectral shape in that the variable component spectra are significantly bluer compared to the polarized flux spectra. This discrepancy in the spectral shape may imply either (1) the decrease of polarization degree in the rest-frame UV wavelengths is not indicating the Balmer absorption edge feature but is induced by some unknown (de)polarization mechanisms, or (2) the UV-optical flux variability is occurring preferentially at the hot inner radii of the accretion disk and thus the variable component spectra do not reflect the whole accretion disk emission.

description: We review recent results on the coherence and superfluidity of driven dissipative condensates, i.e., systems of weakly-interacting non-conserved Bosons, such as polariton condensates. The presence of driving and dissipation has dramatically different effects depending on dimensionality and anisotropy. In three dimensions, equilibrium behaviour is recovered at large scales for static correlations, while the dynamical behaviour is altered by the microscopic driving. In two dimensions, for an isotropic system, drive and dissipation destroy the algebraic order that would otherwise exist, however a sufficiently anisotropic system can still show algebraic phase correlations. We discuss the consequences of this behaviour for recent experiments measuring phase coherence, and outline potential measurements that might directly probe superfluidity.

description: We review models of new physics in which dark matter arises as a composite bound state from a confining strongly-coupled non-Abelian gauge theory. We discuss several qualitatively distinct classes of composite candidates, including dark mesons, dark baryons, and dark glueballs. We highlight some of the promising strategies for direct detection, especially through dark moments, using the symmetries and properties of the composite description to identify the operators that dominate the interactions of dark matter with matter, as well as dark matter self-interactions. We briefly discuss the implications of these theories at colliders, especially the (potentially novel) phenomenology of dark mesons in various regimes of the models. Throughout the review, we highlight the use of lattice calculations in the study of these strongly-coupled theories, to obtain precise quantitative predictions and new insights into the dynamics.

Development of antibiotic-conjugated gelatin type-A for applications in tissue engineering and regenerative medicine

description: Antibiotic resistance continues to pose a social burden and a global challenge in the treatment of infectious diseases. The rates of mortality and morbidity from infections are far greater when caused by drug-resistant organisms. Furthermore, antimicrobial resistance results in increased treatment costs, prolonged hospital stays, and extended treatment times. Surgical site infections, as a key player in antibiotic resistance, is the leading infection in the overall patient population. Research in biomaterials has put forth new approaches to tackle this health threat by redesigning antimicrobial delivery methods, while also leveraging from the unique chemistry of physiologically relevant macromolecules necessary in wound healing. This affords the development of biomaterials that can better target infections to limit systemic and repeated doses of antibiotics and reduce healing time. The objective of this research is to develop a gelatin-based antibacterial biomaterial utilizing carboxyl-containing antibiotics from the β-lactam family for applications in wound healing treatments and regenerative medicine. We employ carbodiimide chemistry to covalently attach ticarcillin, a potent and water-soluble β-lactam antibiotic, to the lysine residues in gelatin type-A and have the antibiotic presented within the gelatin scaffold. We are focusing on antibiotics from the β-lactam family, which inhibit cell wall synthesis. Therefore, cleavage of the antibacterial molecule is not required to inhibit bacterial growth. By covalently incorporating β-lactam antibiotics on gelatin type-A, our goal is to develop a scaffold that presents a covalently attached antibiotic with active drug release when challenged by bacteria; thereby limiting systemic and repeated doses. We confirmed the covalent attachment of ticarcillin to gelatin type-A through FTIR and a fluorescent probe. We validated the purity of the modified gelatin through HPLC analysis. We further studied the antibacterial properties of the modified material as a liquid solution, hydrogel, and fragmented peptide. Finally, we investigated the biocompatibility and antibacterial efficacy of the antibiotic-conjugated gelatin scaffold in vitro. Through this thesis project, we successfully modified gelatin type-A, to afford a biocompatible versatile gelatin composite with antimicrobial properties for applications in tissue engineering and regenerative medicine.

PV System and Grid Integration Aspects

description: 28th European Photovoltaic Solar Energy Conference and Exhibition; 3622-3626
description: This paper provides an analysis on the main voltage regulation techniques, PF(P) and Q(U) that can be
applied in the low voltage (LV) network with standard photovoltaic (PV) inverter technology. The investigations are
done by simulating the power flow in the LV and MV network over one year, with real load and irradiance profiles.
The conclusion is that by installing a certain amount of solar PV in the LV network, the losses in the network can be
reduced. For Denmark with around 70 000 distributions transformers and underlying LV networks, the yearly
reduction of losses in the LV network could supply approximately 14 500 households. Another results is, that a
normal distribution transformer can host up to 140% solar PV power without being significantly over-loaded.

description: In order to determine the profitability of a PV project, power plant operators need to predict
accurately the final energy production. It is crucial to know the operating power of PV modules. The correlation
between the peak power and the operating power is therefore a major issue for several services, such as project
design, operation and maintenance.
In this paper, we explain the conception of a new PV model. Based on a 2012 intern study linking the indoor
measured power to the outdoor measured power, the environment of a plant is modeled in Modelica® code. The
PV modules are modeled by the well-known two-diode model adjusted with 5 parameters. These parameters are
extracted by an algorithm from an I-V curve measured in our AAA flasher. The electrical system (inverters and
MPPT) is taken into account by a variable loss coefficient as a function of input power (inverter efficiency).
Production is obtained by integrating the power during the day. Finally, the model is compared to experimental
measures. The results showed a promising estimation of PV production.

description: In recent years, the costs for electricity produced by PV have fallen below electricity prices of
households and grid parity has been reached. Feed-in laws force plant owners to reduce PV peak power and increase
self-consumption. To ensure the economically efficient operation of PV systems self-consumption, load management
and local storage is vital. Thermal storage combined with a thermal-electrical heating system can be used to reduce
peaks of PV feed-in power and realize a low-cost management system. In this paper, different operation modes of an
oil-fired boiler with an electrical heating rod are introduced and the benefits of an optimized operation mode are
evaluated. With a predictive electric thermal operation it is possible to avoid the shutdown of PV while maximizing
self-consumption.

description: In 2008, Lomonaco and Kauffman introduced a knot mosaic system to define a quantum knot system. A quantum knot is used to describe a physical quantum system such as the topology or status of vortexing that occurs on a small scale can not see. Kuriya and Shehab proved that knot mosaic type is a complete invariant of tame knots. In this article, we consider the mosaic number of a knot which is a natural and fundamental knot invariant defined in the knot mosaic system. We determine the mosaic number for all eight-crossing or fewer prime knots. This work is written at an introductory level to encourage other undergraduates to understand and explore this topic. No prior of knot theory is assumed or required.

description: Work Based Learning (WBL) programmes such as Degree Apprenticeships (DAs) have the potential to widen participation in Higher Education and transform lives, while also supplying the engineering industry with high calibre workforce that are committed, knowledgeable, skilled, and professional. In 2019, Aston University’s Professional Engineering Centre (APEC) developed a suite of level 6 BEng Professional Engineering DA programmes in line with three existing DA standards and in collaboration with major UK manufacturing companies. The curriculum was designed to be flexible and responsive to employers’ needs while ensuring academic and professional development of apprentices aligned with the Knowledge, Skills, and Behaviour (KSB) requirements of the DA standards. This work details our approach in working with employers to develop effective, efficient, and flexible curricula for three DA Programmes launched in January 2020. The case study also outlines the student support measures put in place as part of the successful delivery of this programme to ensure simultaneous academic and professional growth of the apprentices while ensuring compliance with the KSB and the End Point Assessment (EPA) requirements of the DA standards. The success of the programmes in meeting the needs of over 70 apprentices and 15 employers since January 2020 while meeting the rigorous academic and regulatory requirements of such programmes is appraised using feedback from the University validation panel, employer feedback, and apprentices’ feedback from Module Evaluation Questionnaires (MEQs) scores and comments, tripartite review meetings, and programme committee meetings.
