Dynamic modelling, analysis and design of smart hybrid energy storage system for off-grid photovoltaic power systems

Battery technology has been widely utilized in different energy storage applications. However, limitations and challenges such as heat dissipation, low power density, unsatisfactory lifetime characteristics, environmental impacts, and high cost hinder its development in many key areas, for instance, the residential energy storage applications. To address the issue of the short service life of the battery, hybrid energy storage system (HESS) of various designs have been reported in the literature. However the limited focus has been put on the case of the stand-alone residential energy system, especially for remote rural electrification. This thesis aims at proposing suitable batterysupercapacitor HESS designs and control strategies that can effectively extend the battery service lifetime via mitigating its operation stress, thereby realizing the cost reduction on the installing construction and operating costs of the stand-alone photovoltaic (PV) power system. For such systems that is planned to be installed in rural areas, potential suitable battery-supercapacitor HESSs are designed and discussed. To leverage on existing infrastructure in installed standalone PV-battery power system, novel smart supercapacitor/Li-ion HESS plug-in module (SHESS) is proposed to relieve the main battery operation stress. Theoretical analysis and numerical simulations for the designed HESSs and the SHESS are conducted, and their effectiveness in mitigating battery stress are investigated and compared via pulse load testing and case studies with actual data of solar irradiance and load profile from a remote community in Sarawak, Malaysia. A battery health cost model is formulated to qualitatively evaluate the impact of battery current on battery health, thus enabling the estimation of service life improvement as well as the assessment on the economic impact of the remote standalone microgrid. A down-scaled prototype of the proposed HESS is designed and developed to verify the theoretical analysis and analytical findings. Experiments have been carried out to test the feasibility and performance of the proposed system in terms of power-sharing capability in stand-alone PV power system operations. The experimental results demonstrate the feasibility of the proposed HESSs in retrofitting existing installed PV power systems and support the theoretical analysis and simulation outcomes.
Therapy for acute basilar artery occlusion: a systematic review and meta-analysis

Purpose: This study aims to analyse the efficacy of different treatment methods for acute basilar artery occlusion, with an emphasis placed on evaluating the latest treatment methods. Method: A systematic review and meta-analysis was performed to analyse the current data on the therapies available for treating acute basilar artery occlusion. Results: A total of 102 articles were included. The weighted pooled rate of mortality was 43.16% (95% CI 38.35-48.03%) in the intravenous thrombolysis group, 45.56% (95% CI 39.88-51.28) in the intra-arterial thrombolysis group, and 31.40% (95% CI 28.31-34.56%) for the endovascular thrombectomy group. The weighted pooled rate of Modified Ranking Score (mRS) 0-2 at 3 months was 31.40 (95% CI 28.31-34.56%) in the IVT group, 28.29% (95% CI 23.16-33.69%) in the IAT group, and 35.22% (95% CI 32.39-38.09%) for the EVT group. Meta-analyses were also done for the secondary outcomes of recanalization and symptomatic haemorrhage. There was no difference between stent retriever and thrombo-aspiration thrombectomy on subgroup analysis in both clinical outcome and safety profile. Limitations: The included studies were observational in nature. There was significant heterogeneity in some of the outcomes. Conclusions: Superior outcomes and better recanalization rates for acute basilar occlusion were seen with patients managed with endovascular thrombectomy when compared with either intravenous and/or intraarterial thrombolysis. No superiority of stent‐retrievers over thrombo-aspiration thrombectomy was seen.
European hydromedusa Eleutheria dichotoma (Cnidaria: Hydrozoa: Anthomedusae) found at high densities in New South Wales, Australia: distribution, biology and habitat

Eleutheria dichotoma, a hydrozoan not previously recorded from the southern hemisphere, was found at high densities at several locations along the coast of New South Wales (NSW), Australia, between August and November 2005. The identity of the species was confirmed by morphological and molecular (16S rDNA) comparisons with European specimens. Local densities, distribution and habitat (algal substrate) were examined. The medusae were found along a 400 km stretch of coastline between Bateau Bay (33°23′S 151°29′E) and Pebbly Beach (35°35′S 150°43′E), primarily on the green alga Ulva, at mean densities of more than 50 individuals per 10 cm2 plot. The species is probably a recent introduction to Australia.

Scalable Personalized IoT Networks

The Internet of Things (IoT) has enabled unprecedented interactions with our physical world, with the aim to deliver a wide range of customizable services in many domains. With recent advancements in IoT technology, users are increasingly expecting these services to be intelligent and context aware. Nevertheless, there is still no framework capable of delivering personalized IoT services on a large scale. For such a framework to be conceived, it is likely that technologies from many domains have to be utilized. This paper examines the readiness of the leading state-of-the-art technologies in several key fields for realizing the goal of a truly scalable and personalized IoT experience. We discuss the important requirements and challenges for realizing this goal. Then, we identify the major approaches that can contribute to this goal and categorize them into: technologies for adaptive personalized sensing, scalable solutions for user-centric networking, and intelligence techniques that leverage context awareness and adaptability at the application and system levels. In the first category, our discussion centers around virtualization and reprogrammability at the sensing layer. In the second category, we investigate the readiness of Fog computing and information-centric networking to develop scalable personalized IoT infrastructures. These approaches were chosen for their combined ability to match dynamic user requirements with available system resources, while guaranteeing overall efficient utilization. Finally, in the third category, we examine context awareness, reasoning, and machine learning techniques as well as semantic technologies for realizing proactive and adaptive intelligent IoT systems and applications.

NUSOD 2011 Proceedings

Photonic Crystal (PhC) devices owing to their strong confinement of electromagnetic energy are considered to be ideal candidates for on chip optical trapping of dielectric or biological particles in the nanometer range. This would miniaturize optical manipulation devices to a large extent and make them possible on low power integrated silicon platforms. The main challenge in this direction would be the understanding of the type of cavities that are more suitable to optical trapping applications given their unique geometric shapes and mode field overlaps. In this work, we study and present hollow PhC cavities and characterize them for their trapping stiffness, trapping stability and variation of resonance wavelength due to the presence of a particle in the cavity.
Infrahumanization and Mental Travel: Effects of Temporal Orientation on Perceived Humanness

According to the self-centric future hypothesis, mental simulations of future events, future-oriented mental time-travel may incorporate mental representations of the self. This experiment tests the self-centric future hypothesis in the context of infrahumanization. Mental simulations with current self-knowledge are constructed when people think of the future, which may influence the level of humanness they would attribute to strangers. It was predicted that participants in a future-oriented mindset, given their self-centric mental representation of the future, would be less likely than participants in a past-oriented mindset to infrahumanize strangers. There was not a significant direct effect of temporal focus on perceived humanness found. Effects of temporal focus on level of rated humanness were moderated by valence of emotional experiences attributed to others, such that the hypothesis was supported for negatively valenced emotional experiences only. Perceived humanness ratings were significantly higher in the future-oriented than in the past-oriented condition for negatively valenced indicators.
Metabolic rate and growth in the temperate bivalve Mercenaria mercenaria at a biogeographical limit, from the English Channel

Metabolism and growth rate of the hard clam, Mercenaria mercenaria, were investigated in a population invasive to Southampton Water, southern England. An individual metabolic model expressed as a function of soft tissue dry mass was fitted to data of 18 individuals (log (VO2) = −1.952 + 0.543 • log (DM); F1,16 = 201.18, P < 0.001, r2 = 0.926). A von Bertalanffy growth function was fitted to 227 size-at-age data pairs of 18 individuals (Ht = 80.13 • (1 − e−0.149 • (t−0.542)); r2 = 0.927). Individual age-specific somatic production was calculated, demonstrating increase with age to a maximum of 3.88 kJ y−1 at ten years old followed by decrease, and individual age-specific annual respiration was calculated, demonstrating asymptotic increase with age to 231.37 kJ y−1 at 30 years old. Results found here lie within the physiological tolerances reported across the biogeographical range, suggesting that the species' biogeographical limitation in the UK to Southampton Water results from ecological rather than physiological factors.
Life history variation in Pisidium (Bivalvia: Pisidiidae)

Intraspecific variation in the maximum shell length of Pisidium is small in comparison with variation in the life span of the clams, from 4 mo to 4 yr. The use of shell length as a measure of size is complicated by large intraspecific variation in the weight-length relationship, a possible reflection of resource availability on the weight of the soft parts. Maximum embryo length is relatively constant (1 mm) in the majority of species but litter size is variable (1 to 40), generally increasing with parent size. The time of egg-laying is determined by the size of the clam, season, and previous episode of reproduction, while the timing of the release of embryos, depending also on embryonic growth rate, is additionally affected by temperature and oxygen conditions. In brief, the maximum adult and embryo lengths are relatively conservative traits while growth rates vary by an order of magnitude. Reproductive effort, when measured by the ratio of litter weight to parent weight, may increase or decrease with parent length and age. Both semelparous and iteroparous populations are known in several species. We suggest that if maximum adult length can be reached by the first reproductive season (in a favourable environment) the population is semelparous, otherwise (in an unfavourable environment) the population is iteroparous. Gravid clams in semelparous populations continue to grow, and thus assimilation cannot be meaningfully partitioned into reproduction, somatic growth and maintenance. Along a depth gradient from 8 to 65 m, maximum and mature shell lengths, embryo length and litter size varies significantly in Pisidium conventus subpopulations not distinguishable electrophoretically. Large clams in deep water produce large embryos but small litters, which is contrary to the general trend of increasing litter size with parent length. Low food availability that decreases juvenile growth rate may restrict litter size in this case.
A Utilização de Sites de Rede Social no Trabalho: um Estudo de Caso em Empresas Brasileiras

As pessoas estão cada vez mais utilizando sites de rede social (SRS) por meio de plataformas corporativas ou websites abertos tais como Twitter, LinkedIn e Facebook. Como um fenômeno recente, os benefícios e riscos potenciais de tais ferramentas ainda não foram devidamente discutidos nas organizações. O objetivo deste artigo é analisar como as empresas brasileiras estão utilizando essa ferramenta para alcançar seus objetivos estratégicos. Nós realizamos um estudo de caso qualitativo e propusemos um modelo que classificou as empresas em três grupos de acordo com seus posicionamentos em relação ao uso de SRS no trabalho. O grupo de criação de conhecimento privilegia o capital social e intelectual gerado por discussão on-line, enquanto o grupo de marca corporativa procura fortalecer a imagem da empresa perante os consumidores. O grupo de controle administrativo está mais preocupado com a produtividade, procrastinação e confidencialidade dos dados. Nós também destacamos as razões pelas quais os funcionários usam SRS durante o horário de trabalho, os benefícios e os riscos causados pela formação do capital social e preocupações relativas à privacidade.
Reconstructing the potential for the 1D Schr\"odinger equation from boundary measurements

We consider the inverse problem of the determining the potential in the dynamical Schr\"odinger equation on the interval by the measurement on the whole boundary. Provided that source is \emph{generic} using the Boundary Control method we recover the spectrum of the problem from the observation at either left or right end points. Using the specificity of the one-dimensional situation we recover the spectral function, reducing the problem to the classical one which could be treated by known methods. We adapt the algorithm to the situation when only the finite number of eigenvalues are known and provide the result on the convergence of the method.

Should You Target Early Trend Propagators? Evidence from Twitter

Marketing has often stressed the importance of targeting firm communications to consumers who embrace and propagate trends. However, little is known about how possible it is to use advertising to persuade them to embrace the topics a firm wants them to propagate. To explore this, we use data from a field test conducted by a charity on the micro-blogging service Twitter. On Twitter, ‘promoted tweets’ allow advertisers to target individuals whose recent postings contain key phrases. Every day, Twitter identifies which topics are the most popular among Twitter users. In the field test, the charity targeted individuals who embraced a top Twitter trend early on in its life-cycle, and compared their behavior to that of individuals who only embraced the trend later on. We find that targeting advertising to early trend propagators who have embraced non-commercial trends early on is not successful. One explanation is that early trend propagators aim more than others to make their own unguided choices and have little motivation to respond to commercially sponsored topics. In line with this interpretation, we do not find a similar negative effect of targeting individuals who are early propagators of commercially sponsored trends.
A Study on Erioglossum rubiginosum for Evaluation of Biological Properties

s Objectives: Present study was carried outto evaluate Pharmacological (cytotoxic and antimicrobial activities), phytochemical and physicochemical properties of Erioglossum rubiginossum leaves, an evergreen plant, belonging to the family Sapindaceae. Methods: Crude methanol extracts and fraction of the leaves of E. rubiginossum were used for brine shrimp lethality bioassay to identify cytotoxic potential of the extractives compared to Vincristine sulphate. The crude extract (methanol extract and fractions) of E. rubiginossum was screened for their antimicrobial activity against a wide range of bacteria and fungi by disc diffusion method. The phytochemical evaluation was carried out by qualitative analysis. Physicochemical properties was determined according to method (Anonymous 1968) described in British Pharmacopeia. Result: In brine shrimp lethality bioassay, the carbon tetra chloride soluble fraction possessed the highest cytotoxic activity with LC50 value of 11.11±0. 04µg/ml. The LC50 values of fractions were found to be 11.11 to 90. 05µg/ml compared to standard Vincristine sulphate (0.451µg/ml). From these results, it can be well predicted that the leaves of E. rubiginossum possesslow cytotoxic property. In disc diffusion assay, the fractions of E. rubiginosum possessed zone of inhibition ranging from 3.0 to 14.0 mm. Among them, the chloroform soluble fraction had shown highest zone of inhibition 14.0 mm against Salmonella paratyphi. The phytochemical evaluation showed presence of alkaloids, flavonoids, phenols, saponins and carbohydrate. Various physicochemical parameters like moisture content, total ash value, acid soluble ash value, water soluble ash value, alcohol soluble extractive value and water soluble extractive value were to be found 7.20%, 21.00%, 23.00%, 8.50%, 1.00% and 0.50% respectively. Conclosion: Further investigations are required for isolation of active compound that are responsible for antimicrobial activity and cytotoxicity along with their mechanism.
