Selected aspects of electricity generation in a private photovoltaic installation

The article discusses basic types of photovoltaic modules and their use in various configurations of home power plants. The astronomical conditions and estimation of intensity of solar radiation outside the Earth's atmosphere as a factor determining the scope of electricity production are described. The construction of a stationary photovoltaic installation with a capacity of 4.16kW, consisting of 16 polycrystalline photovoltaic panels cooperating with the Fronius inverter is presented. Subsequently, 7 very similar installations were analysed. It was ensured that: analysed installations were oriented southwards with a maximum 2-minute deviation, an angle of panels was similar and ranged from 35 to 38º. Installations have been installed in the same geographical area, at a short distance from one another. Energy produced was monitored during a monitoring of an electricity production process. In an empirical part of this article, energy yields obtained in 2017 are shown. Based on collected data, the analysis showing selected aspects of production, including its repeatability in analysed periods of time, was conducted. Obtained data and mathematical relationships allow to develop models for prediction and diagnostics of plant performance.
A-CACHE: Alternating Cache Allocation to Conduct Higher Endurance in NVM-Based Caches

Recent developments in non-volatile memories (NVMs) have introduced them as an alternative for SRAMs in on-chip caches. Besides the promising features of NVMs, e.g., near-zero leakage power, immunity to radiation-induced particle strike, and higher density, a major drawback of NVM-based caches is their short lifetime due to limited write endurance. This brief first reveals that in L1 caches, the lifetime of data-cache is about 472 $\times$ shorter than that of instruction-cache (I-cache) due to extreme imbalance write stress between the two. Then, we propose a technique, so-called alternating cache allocation to conduct higher endurance (A-CACHE), to improve the lifetime of frequently written D-cache by exploiting rarely written I-cache. The key idea in A-CACHE is to alternate the locations of storing instructions and data between I-cache and D-cache. The evaluation results show that A-CACHE improves the lifetime of the cache by 83% with negligible overheads.
A COMPACT WIDEBAND SLOT ANTENNA FOR UNIVERSAL UHF RFID READER

In this letter, a new wideband circularly polarized antenna for Radio Frequency Identification (RFID) readers is proposed. A prototype operating in the Ultra-High Frequency (UHF) band is successfully realized and tested using a defected Ground Structure (DGS). This antenna consists of an L-shaped metal strip and a DGS with four tuning stubs. The overall size covers 90 ∗ 90 ∗ 1.6 mm3. The measured −10 dB reflection coefficient S11 bandwidth is 27% (800–1020 MHz), and a good radiation pattern and suitable gain coefficient about 3.7 dB have been achieved. Also, an excellent agreement was noticed between simulation and measurement results demonstrating the good performance of the proposed antenna.
Prevalence of Mycobacterium avium subsp. paratuberculosis and associated risk factors in dairies under mechanical milking parlor-systems in Antioquia, Colombia

: The present study aimed to determine Mycobacterium avium subsp. paratuberculosis (MAP) prevalence according to environmental samples and to explore the herd-level risk factors associated to MAP infection in dairy herds under mechanical milking parlor and pasture grazing-based systems. The study herds (n = 94) were located in 60 districts from five municipalities in the Northern region of the province of Antioquia, Colombia. Herds were visited once in 2016 to collect two composite environmental samples and to complete a risk assessment questionnaire. MAP identification was carried out using a quantitative real-time PCR method based on the IS 900 sequence. A herd was considered as MAP-positive if one or both of the environmental samples were found positive by the molecular technique. The information on risk factors was analyzed using a multivariable logistic regression model. The apparent herd-level prevalence found was 14.9 % (14/94; 95 % CI: 7.7-22.1), ranging from 0 to 33.3 % at municipality-level. Herds where other than Pure-Holstein breeds were predominant (i.e. Jersey, Jersey crossbreeds) were more likely to be MAP-qPCR positively infected than those on which where pure-Holstein cattle was predominant (OR=3.7; 95 % CI: 1.1-15.2). The present study reports MAP prevalence in dairy herds in the province of Antioquia (Colombia), and the association between MAP environmental positivity with the predominant breed in the herd.

the Biennial Research Through

: Presented here is a research-through-design exploration into a collaborative process of developing a computer technology in which the visual designer has control. This paper presents the iterative negotiations and key turning points in the process of developing commissioned artifacts used to create and push the boundaries of the software. During this process visual designers learned how to creatively exploit the technology, hack the parameters, work around rules and play with accidents to create technologically enriched interactive patterns. We discuss the designer’s role in this software development process as the link between the technology and the user. There is a shift from the seperation of programming codes and adding imagery later to designing imagery that is interactive.
The Relationship Between Nurse Staffing and Patient Mortality in The Relationship Between Nurse Staffing and Patient Mortality in Medical-Surgical Units Medical-Surgical Units

The purpose of this research was to investigate the relationship between patient mortality and nurse staffing and patient variables. A retrospective, quantitative, cross-sectional design was used, and the sample contained nearly 35,000 patients from 11 medical-surgical units from 4 hospitals. The effect of RN hours per patient day and RN skill mix were compared individually to mortality using binary logistical regression analysis. Patient variables including age, complication index, severity category, and total number of adverse outcomes were also compared to patient mortality. Data was obtained fiom administrative databases from 8 quarters between July 2005 to June 2007. Findings fiom the study suggest that there may be a relationship between mortality and nurse stafEng variables (RN hours per patient day and RN skill mix), but results were not consistent across all 1 1 units. Patient variables, especially age, severity category, and complication index were more consistent across units and therefore seemed to be better predictors of mortality than were nurse staffing variables. These results, along with similar results reported by other researchers, suggest that there is a need to further study the relationship between nurse stang variables and patient outcomes.

Evaluation of Multi-Beam Massive MIMO Considering MAC Layer Using IEEE802.11ac and FDD-LTE

Massive multiple-input multiple-output (MIMO) transmission has attracted attention as a key technology for use in fifth-generation mobile communication systems. Multi-beam massive MIMO systems that apply beam selection in analog components and blind algorithms in digital components to eliminate the requirement for channel state information have been proposed as a method for reducing overhead. In this study, we developed an adaptive modulation scheme for implementing multi-beam massive MIMO and used computer simulation to compare it with digital and analog–digital hybrid beam-forming methods. The effectiveness of the proposed system was verified in a medium access control layer based on the IEEE802.11ac and frequency division duplex-LTE representative wireless communication standards.
role of 6-phosphate in crop yield and resilience

Significant increases in global food security require improving crop yields in favourable and 13 poor conditions alike. However, it is challenging to increase both the crop yield potential and yield 14 resilience simultaneously, since the mechanisms that determine productivity and stress tolerance are 15 typically inversely related. Carbon allocation and use may be amenable to improving yields in a range 16 of conditions. The interaction between trehalose 6-phosphate (T6P) and SnRK1 (SNF1-related/AMPK 17 protein kinases) significantly affects the regulation of carbon allocation and utilisation in plants. 18 Targeting T6P appropriately to certain cell types, tissue types, and developmental stages results in an 19 increase in both yield potential and resilience. Increasing T6P levels promotes flux through 20 biosynthetic pathways associated with growth and yield, whereas decreasing T6P levels promotes 21 mobilisation of carbon reserves and movement of carbon associated with stress responses. Genetic 22 modification, gene discovery through QTL mapping, and chemical intervention approaches have been 23 used to modify the T6P pathway and improve crop performance under favourable conditions, drought, 24 and flooding in the three main food security crops: wheat (Triticum aestivum), maize (Zea mays), and 25 rice (Oryza sativa). Interestingly, both trehalose phosphate synthase (TPS) and trehalose phosphate 26 phosphatase (TPP) genes are associated with maize domestication. A phylogenetic comparison of 27 wheat TPS and TPP with eudicots and other cereals shows strong distinctions in wheat in both gene 28 families. This update highlights recent research examining the potential of the trehalose pathway in 29 crop improvement, and highlights an emerging strategy to increase cereal yields by targeting T6P in 30 reproductive tissue. 31
Adjustable PAPR reduction for DFT‐s‐OFDM via improved general precoding scheme

An improved and specification-compatible general precoding scheme (GPC) for adjustable peak-to-average power ratio (PAPR) reduction in discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) is proposed. Through the rearrangement of periodic padding for precoded data symbols in the GPC precoding matrix, the proposed algorithm does not increase any computational complexity compared to the original GPC. The LTE-based simulation shows the proposed algorithm has a better improvement of PAPR reduction especially in low-order modulations and the performances can be scaled to the other transmission bandwidth. These works contribute to the flexibility of DFT-s-OFDM for supporting 5G transmission over miscellaneous power amplifiers.

Effects of Water Reducing Admixture on Rheological Properties, Fiber Distribution, and Mechanical Behavior of UHPFRC

The rheological properties of ultra-high-performance fiber-reinforced concrete (UHPFRC) according to the amount of water reducing admixture (WRA) and their effects on the fiber distribution and the tensile performance of UHPFRC were investigated. Four types of mixtures with a high compressive strength over 150 MPa were designed according to the amount of WRA and the flowability, rheological properties, compressive strength, flexural performance, and fiber distribution were measured. Test results showed that the amount of WRA influences both the freshly mixed and hardened properties. It was also revealed that the flexural strength has a strong correlation with rheological properties, compressive strength, and fiber distribution.
A ug 2 01 2 ON THE INTERACTION OF ELECTROMAGNETIC WAVES WITH

We study the interaction of electromagnetic waves with electrons. Our results can be applied to radio waves in the ionosphere or to lasers impinging on metals causing melting. We generalize the classical analysis of Zener to the case which includes the interactions of the electrons with lattice vibrations or the positive ions. We use the induced polarization to give a globally coherent and unifying analysis of the two cases, where collisions are important and where they are negligible.
The 4 Arabidopsis Choline/Ethanolamine Kinase Isozymes Play Distinct Roles in 13 Metabolism and Development 1,2 14

41 Phosphatidylcholine and phosphatidylethanolamine are 2 major phospholipid classes in 42 eukaryotes. Each biosynthesis pathway starts with the phosphorylation of choline (Cho) 43 or ethanolamine (Etn) catalyzed by either choline or ethanolamine kinase (CEK). 44 Arabidopsis contains 4 CEK isoforms but their isozyme-specific roles in metabolism and 45 development are poorly described. Here, we showed that these 4 CEKs have distinct 46 substrate specificities in vitro . While CEK1 and CEK2 showed substrate preference for 47 choline over ethanolamine, CEK3 and CEK4 had a clear substrate specificity for choline 48 or ethanolamine, respectively. In vivo , CEK1, CEK2, and CEK3 exhibited kinase activity 49 for choline but not ethanolamine, although the latter 2 isoforms showed rather minor 50 contributions to total choline kinase activity in both shoots and roots. The knockout 51 mutants of CEK2 and CEK3 both affected root growth, and these isoforms had 52 non-overlapping cell-type-specific expression patterns in the root meristematic zone. 53 In-depth phenotype analysis, as well as chemical and genetic complementation, revealed 54 that CEK3, a choline-specific kinase, is involved in cell elongation during root 55 development. Phylogenetic analysis of CEK orthologs in Brassicaceae species showed 56 evolutionary divergence between Etn kinases and Cho kinases. Collectively, our results 57 demonstrate the distinct roles of the 4 CEK isoforms in choline/ethanolamine metabolism 58 and plant development. 59
Simulation of a solar absorption system

This paper describes the dynamic modeling of a solar absorption cooling plant that will be built for both research and demonstration purposes by the end of 2007. The synchronizing of cooling loads with solar radiation intensity is an important advantage when utilizing solar energy in air conditioning in buildings. The first part of this work deals with the dynamic modeling of an evacuated tube collector. A field of these collectors feed a single-effect absorption chiller of 35 kW nominal cooling capacity. The simulation model has been done in a modular way under TRNSYS16. In a second part, simulation and optimization of the system has been investigated in order to determine the effect of several parameters (collector area, tank volume.) on chiller performance.
Fault diagnosis in switched‐linear systems by emulation of behavioral models on FPGA: A case study of current‐mode buck converter

This paper presents an Field‐Programmable Gate Array (FPGA)‐based fault emulation and detection framework for switched‐linear systems commonly encountered in power electronics. The proposed framework exploits high‐level behavioral modeling that maps analog functionality into fixed‐point architectures supported by FPGAs. This work is mainly concerned with modeling and validation of effectiveness of a fault diagnoser of a power converter much before its fabrication. The proposed concept of fault diagnosis at presilicon stage overcomes several reliability issues in power electronic systems and enables design and development of test resources, verification of test bed, and interconnecting circuitry at an early stage of the design. To illustrate applicability of this environment, well‐accepted fault events including hard and soft faults are emulated with the help of a nonideal model of a buck converter and a piecewise linear detection filter, which follow an observer‐based residual generation for fault detection. The paper also shows that the proposed method is equally applicable for detection of faults under unstable operation of the converter. The effectiveness of the proposed framework is evaluated through FPGA‐based simulation (or “emulation”) of a peak‐current‐mode–controlled buck‐type switching converter implemented on Xilinx Kintex‐7 FPGA in MATLAB/Simulink environment with Xilinx System Generator support. To the best of our knowledge, fault diagnosis in power converter by emulation of its nonideal model on FPGA is attempted for the first time in the literature. Experimental results show that power converter faults can be easily detected by monitoring detection filter residuals while some of the faults can be precisely identified.
TESTING FOR CHANGES IN THE LONG-RUN CAUSAL STRUCTURE OF COINTEGRATED VECTOR AUTOREGRESSIONS

In this paper we examine, using Monte Carlo methods, several alternative approaches to detecting changes in the long-run causal structure of cointegrated VARs. We adopt recursive and rolling techniques as misspecification tests for the detection of instabilities in the adjustment coefficients and of the breakpoints. The results show that the recursive eigenvalues are not able to highlight a break in the causal structure of the models, whilst the recursive coefficients only show non-constancy of the parameters of interest. Rolling estimation is found to perform better in detecting instability in the parameters and their true value after the breakpoint. However, it only detects a region where the break is likely to occur. To overcome the drawbacks of these techniques, we propose an OLS-based sequential-dummy test. We derive its critical values for different sample sizes and discuss its statistical properties. We show that it has a non-standard distribution and reasonable power even in small samples. It is also a useful graphical device, as it shows a kink at the breakpoint. However, it is not able to deal with the case of multiple breakpoints. Here a possible solution is represented by the use of the Kalman filter. We analyse its performance on the same DGPs. The results confirm its effectiveness as a graphical tool, but they also indicate that it exhibits relatively wide margins of error, suggesting that its efficiency is sometimes limited.
