MATLAB/Simulink model of stand alone Solar PV system with MPPT enabled optimized Power conditioning unit
Venue: 2016 IEEE 7th Annual Information Technology, Electronics and Mobile Communication Conference (IEMCON)

This paper deals with modelling of a stand alone solar PV system with MPPT (Maximum Power Point Tracking) algorithm to enhance its efficiency for a dedicated load pattern. The Perturb Observe (P&O) algorithm has been used to track the maximum power operating point of 80WP stand alone Solar PV system. Here the DC DC Boost converter has been designed as a Power conditioning unit for controlling the operating point of the PV source to achieve the MPP that enhances overall system efficiency.
Book Review: The Oxford Handbook of US Environmental Policy

broad focus and contains chapters about reasons behind the shootings, for example, mental health issues (Schildkraut and Muschert) gender and school shootings (Kellner) and the role of alienation (Worrell) The latter part of the book focuses on the correlation between gun ownership and support for the death penalty (Young) the cultural mythology of gun ownership (Welch) and police attitudes towards gun policy (Carlson) The editors attempt to be objective in their treatment of this highly controversial topic. They are mostly successful as a few chapters include arguments from both a pro gun control stance and the National Rifle Association stance. However, most chapters are more focused on positive effects of enhanced gun control measures. There are some weaknesses, as is common in edited volumes, with chapters of varying quality, and there is a focus on school shootings. The chapter by Schildkraut and Muschert relies heavily on quotes, yet page numbers are not provided for the quotes. It is a strength that chapters range from political theory approaches to quantitative approaches to gun violence. This book provides a good introduction to reasons behind (mass) gun violence and the gun control debate in the United States. The book would have benefited from a chapter about the role of the second amendment and one about the role of the judiciary, since both are prevalent in the gun control debate in the United States.
Decentralisation et qualite de l'offre de services socio publics en Afrique subsaharienne Decentralization and quality of social service delivery in sub Saharan Africa

Decentralization and quality of social service delivery in sub Saharan Africa The purpose of this paper is to analyze, from a purely microeconomic perspective, the impact of decentralization on the quality of the delivery of social services in sub Saharan Africa. The analysis uses data from the Afrobarometer Round 4 survey, which collected information on the views of citizens on governance, democracy, economic reform, civil society, and the quality of life in 20 African countries. Results of the econometric analysis show that a high degree of decentralization and/or a high quality of democracy promote good governance and in turn the provision of highquality public services. The process of decentralization in Africa is thus generally beneficial to the population from the perspective of the quality of social and public service delivery. However, while overall decentralization has a positive and significant impact on the quality of public service delivery, the results are mixed when the analysis is conducted by country.

Hybrid Pulsewidth Modulated Single Phase Quasi Z Source Grid Tie Photovoltaic Power System
Venue: IEEE Transactions on Industrial Informatics

A hybrid pulsewidth modulated single phase quasi Z source grid tie photovoltaic (PV) power system is proposed. The hybrid pulse width modulation (HPWM) combines the pulse width modulation (PWM) and the pulse amplitude modulation (PAM) The PWM works when the ac output voltage is lower than the dc source voltage; otherwise, the PAM operates the single phase quasi Z source inverter (qZSI) The HPWM leads to the reduction of power loss, and the quasi Z source capacitance and inductance. An effective control strategy is proposed for the new PV power system to manage the maximum power point tracking (MPPT) of PV panel, grid tie power injection, and dc link voltage. A grid tie current controller, combining a repetitive controller and a proportional resonant regulator, achieves strong harmonic suppression, fast dynamic, and zero tracking error. A 500 W prototype is built to verify the new system. Power loss estimation and impedance design are detailed. Experimental tests validate the HPWM, new PV power system with higher efficiency, and the related control method.
PISCES: A Programmable, Protocol Independent Software Switch
Venue: SIGCOMM

Hypervisors use software switches to steer packets to and from virtual machines (VMs) These switches frequently need upgrading and customization to support new protocol headers or encapsulations for tunneling and overlays, to improve measurement and debugging features, and even to add middlebox like functions. Software switches are typically based on a large body of code, including kernel code, and changing the switch is a formidable undertaking requiring domain mastery of network protocol design and developing, testing, and maintaining a large, complex codebase. Changing how a software switch forwards packets should not require intimate knowledge of its implementation. Instead, it should be possible to specify how packets are processed and forwarded in a high level domain specific language (DSL) such as P4, and compiled to run on a software switch. We present PISCES, a software switch derived from Open vSwitch (OVS) a hard wired hypervisor switch, whose behavior is customized using P4. PISCES is not hard wired to specific protocols; this independence makes it easy to add new features. We also show how the compiler can analyze the high level specification to optimize forwarding performance. Our evaluation shows that PISCES performs comparably to OVS and that PISCES programs are about 40 times shorter than equivalent changes to OVS source code.
Navigating the boys' club: Debra DiGiovanni and the performative strategy of comic self deprecation

This article considers Canadian comedian Debra DiGiovanni's self deprecatory humour as a performative strategy. In keeping with a performance tradition of self deprecation as established by women like Phyllis Diller and Joan Rivers, DiGiovanni offers 'failure' as a comic strategy. Her comedy is heavily reliant upon the framing of her lack in relationships, in self control and in body image (in relation to normative gender standards and expectations) At the same time, however, DiGiovanni also engages critically with gendered expectations of heteronormative desirability, lampooning thin women, superficial men and celebrity culture. Although her comedy is generally characterized by self deprecation, her humour also leaves space for an ambivalent politics of gender.

Economics and psychology. The framing of decisions

In the Theory of Rational Decision Making the psychological aspects are set aside. This contribution seeks to point out the relevance of psychology into economic decisions. The essay treats the "framing of decisions" which is a pillar of Kahneman's behavioral theory. Framing must be considered a special case of the more general phenomenon of dependency from the representation. The best known risky choice framing problem, i.e. the "Asian Disease Problem" is shown where an essential aspect of rationality: invariance, is violated. In addition, the contribution explains Kahneman and Tversky's Prospect Theory and illustrates their value function. Finally, it discusses the reversals of preference in framing and framing of contingencies. The framing manipulation is viewed as a public tool for influencing the decision maker's private framing of the problem in terms of gains or losses, which determines the decision maker's evaluation of the options. In conclusion, the psychology of choice is relevant both for the descriptive question of how decisions are made and for the normative question of how decisions ought to be made.
Digital image analysis outperforms manual biomarker assessment in breast cancer
Venue: Modern Pathology

In the spectrum of breast cancers, categorization according to the four gene expression based subtypes 'Luminal A, 'Luminal B, 'HER2 enriched, and 'Basal like' is the method of choice for prognostic and predictive value. As gene expression assays are not yet universally available, routine immunohistochemical stains act as surrogate markers for these subtypes. Thus, congruence of surrogate markers and gene expression tests is of utmost importance. In this study, 3 cohorts of primary breast cancer specimens (total n=436) with up to 28 years of survival data were scored for Ki67, ER, PR, and HER2 status manually and by digital image analysis (DIA) The results were then compared for sensitivity and specificity for the Luminal B subtype, concordance to PAM50 assays in subtype classification and prognostic power. The DIA system used was the Visiopharm Integrator System. DIA outperformed manual scoring in terms of sensitivity and specificity for the Luminal B subtype, widely considered the most challenging distinction in surrogate subclassification, and produced slightly better concordance and Cohen's k agreement with PAM50 gene expression assays. Manual biomarker scores and DIA essentially matched each other for Cox regression hazard ratios for all cause mortality. When the Nottingham combined histologic grade (Elston Ellis) was used as a prognostic surrogate, stronger Spearman's rank order correlations were produced by DIA. Prognostic value of Ki67 scores in terms of likelihood ratio kh2 (LR kh2) was higher for DIA that also added significantly more prognostic information to the manual scores (LR Dkh2) In conclusion, the system for DIA evaluated here was in most aspects a superior alternative to manual biomarker scoring. It also has the potential to reduce time consumption for pathologists, as many of the steps in the workflow are either automatic or feasible to manage without pathological expertise.
Using goal driven deep learning models to understand sensory cortex
Venue: Nature Neuroscience

Fueled by innovation in the computer vision and artificial intelligence communities, recent developments in computational neuroscience have used goal driven hierarchical convolutional neural networks (HCNNs) to make strides in modeling neural single unit and population responses in higher visual cortical areas. In this Perspective, we review the recent progress in a broader modeling context and describe some of the key technical innovations that have supported it. We then outline how the goal driven HCNN approach can be used to delve even more deeply into understanding the development and organization of sensory cortical processing.
Natural Synthesis and Contemporary Nigerian Visual Arts: An Exposition of Uche Okeke's Works

The frontiers of contemporary Nigerian art are expanding as ethnic traditions have continued to evolve in individual genius which gives it expression. In the visual art of Uche Okeke, we see a synthesis of old and new, hence a perpetuation of old artistic Nigeria traditions in modern artistic sensibility. Although a great deal has been written about Uche Okeke's exploit in arts, the corpus of his oeuvres requires continuous investigation alongside a myriad of artistic developments in Nigeria. More so, there is a dearth of scholarly materials in the global arena on the creative achievements of the artist which anchor on his philosophy of natural synthesis. This paper therefore examined the concepts of synthesis as an art making philosophy and as a creative paradigm inherent in the visual art of Uche Okeke. It also looked at his methods and styles of creating art works alongside those entrenched in traditional uli art practice.
The Management of Information to Identify the Submarine Cable Route: the Case Study of Campania islands

Nonnis, O. Maggi, C. Lanera, P. Proietti, R. Izzi, A. Antonelli, P. and Gabellini, M. 2016. The management of information to identify the submarine cable route: the case study of Campania island.  Vila Concejo, A. Bruce, E. Kennedy, D.M. and McCarroll, R.J. (eds. Proceedings of the 14th International Coastal Symposium (Sydney, Australia) Journal of Coastal Research, Special Issue, No. 75,  Coconut Creek (Florida) ISSN 0749 0208. Offshore pipelines and cables are infrastructures frequently located in the midst of delicate marine ecosystems. The route definition is one of the more complex and strategic aspect for the operation of laying a submarine cable or pipeline. In the designing phase different cable's routes are selected analyzing in detail the natural and/or anthropogenic constraints of the areas to be crossed, to identify the optimal alternative with less environmental impact. A multidisciplinary approach is needed to group all the area's and infrastructure's information, like bathymetry, regional geology, environmentally sensitive areas, shipwrecks, existing infrastructures, potential geohazards, geomorphology, meteocean observations and boundary information. Through an instrument named Desk Top Study (DTS) the information are analyzed and overlapped for the evaluation of the different route hypothesis and the design of appropriate survey programs. In this context TERNA S.p.A. (concessionaire company in Italy for the transmission and dispatching of electricity) charged ISPRA to perform the Desk Top Study for the connection between the coast of Campania peninsula and the islands of Capri and Ischia. Data relating to the areas affected by the electrical connections, collected through the DTS, were managed by a geographic information system (GIS) capable to organize different types of information, thus providing substantial support for the definition of the preliminary route. This work presents the methodology and the main results of the Desk Top Study, carried out for the electric cables laying between the coast of Campania peninsula and the islands of Capri and Ischia.
Effect of plant growth regulators on flower and bulb production of Hippeastrum (Hippeastrum hybridum Hort.

The experiment was conducted at the Horticultural research field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Salna, Gazipur during October 2008 to July 2009 to investigate the effect of plant growth regulators on flower and bulb production of Hippeastrum. There were ten treatments comprising of three concentrations of three growth regulators viz. IAA (20, 60 and 100 ppm) ethrel (100, 300 and 500 ppm) and GA 3 (100, 300 and 500 ppm) along with control (soaked in water) The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Flower and bulb characteristics of Hippeastrum were influenced significantly by different levels of growth regulators. Application of IAA at 60 and 100 ppm and GA3 at 100, 300 or 500 ppm twice as foliar spray at an interval of 30 days promoted the number of bulblets on the treated plants. Ethrel at a concentration of 100 ppm increased the number of flowers per scape (4) and showed earliness in days to flower scape emergence (72.33 days) and first flower open (88.67 days) On the other hand, the biggest size of flower (15.14 cm x 12.44 cm) and flower scape (40.28 cm x 21.95cm) at harvest and the maximum days for flowering (11.50 days) were evident from plants treated with 500 ppm GA 3 The highest number of bulblets per plot (40.00) bulbs weight per plot (4056 g) along with bulb yield (40.56 t/ha) were also obtained in GA 3 at 500 ppm.

Experimental characterization of consensus protocol for decentralized smart grid metering

The availability of intelligence at substation level, combined with the adoption of pervasive communication networks, offers technologies and opportunities to decentralized smart grid metering and control. In this domain self organizing sensor networks equipped by distributed consensus protocols have been recognized as an effective enabling paradigm. The performance of these protocols is usually evaluated in simulation environments without considering the effects of real measurement transducers, data acquisition systems and communication systems. Attention is rarely paid to the influence of factors such as: the measurement uncertainty of the transducers, the effect of the limited bandwidth available on real radio systems, and the change of performance when real nodes enter and exit from the network during or among consensus procedure. The large scale deployment of this paradigm asks for comprehensive analysis aimed at assessing the impact of the non idealities characterizing the real power system environment on the cooperative protocols performance. Armed with such a vision this paper aims at characterizing the performance of distributed consensus protocols in presence of uncertainty and non ideality of the measurement instruments, of the measurement process and of the communication channel in a smart grid environment. Results obtained in simulation and real scenarios might be helpful hints in the implementation and use of this protocol in real networks.
Certain subclass of analytic functions defined by means of differential subordination

For \alpha\in(\pi, \pi] let \mathcal{R}_\alpha(\phi) denote the class of all normalized analytic functions in the open unit disk \mathbb{U} satisfying the following differential subordination: $f'(z)\frac{1}{2}\left(1+e^{i\alpha}\right)zf'(z)\prec\phi(z)\qquad (z\in\mathbb{U} where the function \phi(z) is analytic in the open unit disk \mathbb{U} such that \phi(0)=1$ In this paper, various integral and convolution characterizations, coefficient estimates and differential subordination results for functions belonging to the class \mathcal{R}_\alpha(\phi) are investigated. The Fekete Szeg\"{o} coefficient functional associated with the $k$th root transform  of functions in \mathcal{R}_\alpha(\phi) is obtained. A similar problem for a corresponding class \mathcal{R}_{\Sigma;\alpha}\phi) of bi univalent functions is also considered. Connections with previous known results are pointed out.
Transcriptome Analysis of an Anthracnose Resistant Tea Plant Cultivar Reveals Genes Associated with Resistance to Colletotrichum camelliae
Venue: PloS one

Tea plant breeding is a topic of great economic importance. However, disease remains a major cause of yield and quality losses. In this study, an anthracnose resistant cultivar, ZC108, was developed. An infection assay revealed different responses to Colletotrichum sp. infection between ZC108 and its parent cultivar LJ43. ZC108 had greater resistance than LJ43 to Colletotrichum camelliae. Additionally, ZC108 exhibited earlier sprouting in the spring, as well as different leaf shape and plant architecture. Microarray data revealed that the genes that are differentially expressed between LJ43 and ZC108 mapped to secondary metabolism related pathways, including phenylpropanoid biosynthesis, phenylalanine metabolism, and flavonoid biosynthesis pathways. In addition, genes involved in plant hormone biosynthesis and signaling as well as plant pathogen interaction pathways were also changed. Quantitative real time PCR was used to examine the expression of 27 selected genes in infected and uninfected tea plant leaves. Genes encoding a MADS box transcription factor, NBS LRR disease resistance protein, and phenylpropanoid metabolism pathway components (CAD, CCR, POD, beta glucosidase, ALDH and PAL) were among those differentially expressed in ZC108.
Educar en la sociedad de la informacion

Pretendemos profundizar en los aspectos mas relevantes, desde el punto de vista educativo, de lo que se ha dado en llamar la Sociedad de la Informacion, una sociedad fuertemente tecnologica, en la cual las formas de comunicacion se han potenciado al maximo. Si es verdad que las pautas comunicativas son una caracteristica fuertemente distintiva de la sociedad actual, tambien es cierto que otras caracteristicas de caracter economico, social, cultural y politico acompanan al desarrollo tecnologico en una carrera en la que se podria exigir una mayor clarificacion de metas y objetivos a largo plazo. Pero fundamentalmente interesa destacar como la educacion se esta replanteando en los nuevos contextos sociales y en esta reestructuracion tienen un papel fundamental, no solo la incorporacion de las tecnologias emergentes a los procesos de ensenanza aprendizaje sino tambien la ampliacion de los ambitos de formacion, la elaboracion y distribucion de los materiales didacticos, en concreto los objetos digitales abiertos, la profesionalizacion del profesorado, el replanteamiento de los objetivos y estrategias de ensenanza formal y no formal, en definitiva, la reestructuracion del sistema educativo tal como ha pervivido hasta nuestros dias.
Perfiles de exclusion y politicas de inclusion en Espana: las dimensiones del cambio

El articulo dibuja, en primer lugar, el contexto europeo de las politicas de inclusion social. Lo hace por medio de una doble perspectiva: comparada (diversidad de regimenes de bienestar) y dinamica (diversidad de trayectorias de reestructuracion) Sobre esta base, el analisis se despliega en dos grandes apartados. Por un lado se trazan las bases empiricas del objeto de estudio: la arquitectura institucional de las politicas de inclusion social actualmente existentes en Espana, asi como los principales perfiles de la pobreza, la exclusion y la desigualdad en perspectiva espanola y europea comparada. Por otro lado se consideran los retos a afrontar y las propuestas para encararlos. La dinamica propositiva se desarrolla en tres dimensiones: la discursiva, donde se fortalece el relato de los ejes de exclusion/inclusion, y de la nueva pobreza; la sustantiva, donde se perfilan alternativas de inclusion social como dignidad (rescate ciudadano) y autonomia personal (atencion a la dependencia y nuevo paradigma de servicios sociales) y la operativa, donde se apuesta por la proximidad y las redes de accion como medio para la practica de la inclusion social. El documento ofrece una perspectiva emergente de variables, que surgen tras los anos mas intensos de crisis economica (2007 2012) y de politicas europeas de austeridad (2010 2015) La creciente distancia entre los impactos de todo ello y la debilidad relativa de unas politicas de inclusion, de consolidacion muy tardia en los regimenes de bienestar, lleva a concluir la necesidad de un fortalecimiento de las estrategias de inclusion, las cuales deberian jugar papeles mas centrales e intensos en el nuevo ciclo de los regimenes de bienestar que, tras la crisis, se abre en Espana y el conjunto de la Union Europea
