Radio propagation prediction for selected locations in Sun-U campus: a ray tracing approach using image method

Radio propagation prediction is a crucial step to determine the propagation characteristics of any arbitrary installation for the implementation of a mobile radio system. This is especially true for telecommunication systems that use electromagnetic waves for information transfer instead of relying on the conventional way that use electrical currents. In this paper, a ray tracing approach using image method is adopted to perform radio propagation predictions in two selected areas of Sun-U Campus, namely an empty hallway located on the second floor in the School of Computer Technology (SCT), and its adjacent academic staff rooms. The values of electrical parameter such as dielectric constant (relative permittivity) of different materials are altered assuming the walls that separate each academic staff room are made of rubber, glass, and plasterboard. How this variation affects radio wave propagation prediction is discussed while the main propagation mechanisms traveling along the empty hallway are reported.

Experiential knowledge of positive and negative experiences onremembrance and neural response using neuro signature system.

Understanding the human mind has always been a very complex process and so does emotional impact on individual. Positive and negative interpretations of events create deep impacts on memory due to which a person remembers such events and may feel happy or sad. The experiences are created due to four aspects i.e. sensory interpretations, motor responses, proprioceptive response, and emotional arousal. However, individual remembers the negative events better as compared to positive events and responds more to the negative emotions as compared to positive emotions. This research paper explores the human brain and its neural response with reference to positive and negative experiences of an individual through the unique technique Neuro Signature System i.e. Brain Electrical Oscillations Signature profiling (BEOS) developed by Prof. C.R Mukundan. This technique tries to investigate the some of the major cognitive neural networks and various aspects of participation of a person in a particular event. The paper focuses on the impact of negative and positive experiences of an individual and its remembrance. For this study, total 20 participants were selected of age group between 20-25 years. Their remembrance of positive and negative events was tested by using the BEOS system. The results of the study concluded that though the negative experiences were remembered in greater elaboration, both types of experiences were equally remembered. The participants elicited Experiential Knowledge (EK) scores while remembering both their positive and negative life events, although it was difficult to give elaborated version of positive experiences but the number of EKs produced for event remembered was almost equal when positive and negative experiences were share by the participants.
Photometric and spectroscopic variability of the FUor star V582 Aurigae

Kiso Observatory, Institute of Astronomy, School of Science, the University of Tokyo, Mitake-mura, Kiso-gun, Nagano-ken 397-0101, JapanReceived ; acceptedABSTRACTAims.We present results from optical photometric and spectroscopic observations of the eruptive pre-main sequence star V582 Aur.Variability of the star was reported a few years ago when it was suspected as a possible FU Orionis object. Due to the small numberof currently known FUors, a new object of this type is ideal target for follow-up photometric and spectroscopic observations.Methods. We carried out BVRI CCD photometric observations in the ﬁeld of V582 Aur from 200 9 August to 2013 February. Weacquired high-, medium-, and low-resolution spectroscopyof V582 Aur during this period. To study the pre-outburst variability of thetarget and construct its historical light curve, we searched for archival observations in photographic plate collections. Both CCD andphotographic observations were analyzed using a sequence of 14 stars in the ﬁeld of V582 Aur calibrated in BVRI.Results. The pre-outburst photographic observations of V582 Aur show low-amplitude light variations typical of T Tauri stars.Archival photographic observations indicate that the increase in brightness began in late 1984 or early 1985 and the star reached themaximum level of brightness at 1986 January. The spectral type of V582 Aur can be deﬁned as G0I with strong P Cyg proﬁles ofHα and Na I D lines, which are typical of FU Orionis objects. Our BVRI photometric observations show large amplitude variations∆V ∼ 2
Social structure and residency in aggregations of male sperm whales

Sperm whales (Physeter macrocephalus) are sexually dimorphic in several respects, including size, latitudinal distribution, and social structure. Females are known to have complex social structures, including long-term bonds, but the social structures of sexually mature or maturing males have received much less attention. Using data from aggrega- tions of males off Norway, Nova Scotia, New Zealand, and the Galapagos Islands, we examined aggregation size, resi- dence times within aggregations, clustering at the surface, and long-term bonds. Results were generally consistent among study areas. The aggregations found in each area contained around 10-30 males at any time, and were usually a few tens of kilometres across. Mean residence times within aggregations ranged from a few days to a few weeks. Close clustering at the surface was rare, but present at each site. There was no evidence for preferred companionship between individuals at any temporal scale in any of the study areas. The rarity of clustering and the apparent lack of long-term relationships amongst male sperm whales contrast strongly with results of studies on females, suggesting that both close spatial proximity at the surface and permanent bonds between individuals may be a consequence of the need for care of the young. Resume : Les cachalots (Physeter macrocephalus) presentent un important dimorphisme sexuel, notamment en taille, en distribution latitudinale et en organisation sociale. Les femelles ont une organisation sociale tres complexe qui inclut des associations a long terme entre individus, alors que l'organisation sociale des mâles adultes, ou subadultes, reste encore largement inconnue. En utilisant des donnees provenant de regroupements de mâles au large de la Norvege, de la Nouvelle Ecosse, de la Nouvelle Zelande et des Iles Galapagos, nous avons examine la taille des regroupements, la duree du sejour a l'interieur de ces regroupement, la maniere dont les individus se rassemblent a la surface et les asso- ciations a long terme entre individus. Les resultats etaient coherants d'une region a l'autre. En general, les regroupements avaient quelques dizaines de kilometres de diametre et contennaient environ 10-30 mâles. La duree moyenne du sejour a l'interieur de chacun de ces regroupements allait de quelques jours a quelques semaines. Les individus formaient rarement des groupes compacts de deux ou plusieurs individus separes par moins de 100 m, mais de tels groupes ont ete observes en surface dans chaque region. Rien dans nos donnees, dans aucune region, ni a aucune des echelles temporelles etudiees, ne laissait croire que certains individus puissent s'associer plus souvent avec tel mâle qu'avec tel autre. Le fait que les individus se regroupaient rarement a la surface et l'absence d'associations a long terme entre mâles presentent un contraste remarquable avec les resultats obtenus chez les femelles. Cela suggere que la proximite spatiale a la surface ainsi que les associations permanentes entre individus servent principalement a assurer les soins aux jeunes.
Re-imagining global union representation under globalisation: a case of seafaring labour and the Nautilus International cross-border merger

This paper reflects on the opportunities and challenges for labour movement revitalisation through cross-border organising. It considers whether, and how, unions may innovate and present a united front, where transnational employers actively seek to divide and fragment labour for cost advantage. The analysis examines the relevance of path-dependency theory to an explanation of some of the observed limitations to innovation and adaptability among unions. In the light of growing debates about union renewal in the context of globalisation, we examine the obstacles to an effective response to global capital by national unions using the illustrative example of Nautilus International (NI). We conclude that cross-border union organising strategies, such as adopted by NI, are essential to sustain effective representation but great challenges, related to path-dependency exist.
The Effects of Acid Passivation, Tricresyl Phosphate Presoak, and UV/Ozone Treatment on the Tribology of Perfluoropolyether- Lubricated 440C Stainless Steel Couples

Research on the boundary lubrication performance of two perfluoropolyether (PFPE) thin films in the presence of passirated 440C stainless steel is presented. The study used a standard ball-on-disc (BoD) tribometer operating in dry nitrogen and a vacuum spiral orbit tribometer (SOT). Stainless steel surfaces were passivated using one of four techniques: a high-temperature and low-temperature chromic acid bath, a tricresyl phosphate (TCP) soak, or UV/ozone treatment for 15 min. After passivation, each BoD disc had a 400 A film of Krytox® 16256 (PFPE) applied to it. The lives of these films were quantified by measuring the number of sliding cycles before an increase in friction occurred. The lubricated life of the 440C couple was not altered as a result of the various passivation techniques. The resulting surface chemistry of each passivation technique was examined using X-ray photoelectron spectroscopy. The SOT was used to examine the effects of the TCP treatment on the lubricated life of another PFPE, Brayco® 815Z, under rolling conditions. None of the passivation techniques were found to increase dramatically the oxide film thickness or lubricated life.
TRACKING THE ITALIAN EMPLOYEES’ TFR OVER THEIR WORKING LIFE CAREERS

In this paper we evaluate the expected evolution of the Trattamento di ne rapporto over the Italian employeesworking life careers. We use adiminstrative (INPS) data to disentangle the amount that is expected to be accumulated until retirement, the amount expected not to accrue because of discountinuos working careers and/or paid as an anticipated withdrawal. This is relevant in the light of the recent pension system reforms that encourage the diversion of the TFR to pension funds. I thank Christian Bartolucci, John.V.

Validation of an hourly resolved global aerosol model in answer to solar electricity generation information needs

Abstract. Solar energy applications need global aerosol optical depth (AOD) information to derive historic surface solar irradiance databases from geostationary meteorological satellites reaching back to the 1980's. This paper validates the MATCH/DLR model originating in the climate community against AERONET ground measurements. Hourly or daily mean AOD model output is evaluated individually for all stations in Europe, Africa and the Middle East – an area highly interesting for solar energy applications being partly dominated by high aerosol loads. Overall, a bias of 0.02 and a root-mean-square error (RMSE) of 0.23 are found for daily mean AOD values, while the RMSE increases to 0.28 for hourly mean AOD values. Large differences between various regions and stations are found providing a feedback loop for the aerosol modelling community. The difference in using daily means versus hourly resolved modelling with respect to hourly resolved observations is evaluated. Nowadays state-of-the-art in solar resource assessment relies on monthly turbidity or AOD climatologies while at least hourly resolved irradiance time series are needed by the solar sector. Therefore, the contribution of higher temporally modelled AOD is evaluated.
The double-deficit hypothesis and prediction of dyslexia

Background: The double-deficit hypothesis is based on research findings showing that there are correlations between phonological awareness and Rapid Au- tomatized Naming in groups of dyslexic children. The phonological awareness is a generalised term labelling all levels of conscious knowledge of the sound elements of speech. The speed of naming is a complex integration of many processes related to the cognitive and linguistic spheres and it is defined through rapid automatic nam- ing of colours, drawn objects, numbers and/or letters. Hypothesis: Phonological awareness and rapid naming (as components of the double-deficit hypothesis) are associated, to a certain degree, with the speed of reading. Children at risk of dyslex- ia have lower scores in naming speed, phonological awareness or both. Results: On one hand, a significant statistic relation is discovered between the speed of reading and the phonological awareness. On the other hand, there is a moderate statistic re- lation between speed of reading and rapid naming. Double-deficit hypothesis is a theoretical model that can explain most of the reading disabilities (dyslexia), but not
Oral Naturally Derived Agents as an Adjuvant Photoprotection after Dermatologic Surgery

To be effective in protecting against the harmful effects of ultraviolet radiation (UVR), many photoprotective strategies have been used. Inadequate physical protection, amount of topical application, and allergic reactions to topical agents are limitations asso - ciated with current photoprotective strategies. Systemic agents are an emerging alterna -tive, providing promising protection against UVR. This chapter will thoroughly review photoprotective outcomes of oral naturally derived agents from randomized controlled trials using evidence-based method. From total 24 clinical trials with 850 participants, two categories of naturally derived agents were identified. Plant-derived agents include beta-carotene, green tea, golden serpent fern, tomato, cocoa bean, and vitamin E, whereas animal-derived products consist of nicotinamide and omega-3 polyunsaturated fatty acids. In conclusion, systemic plant and animal-derived photoprotective agents may be a promising alternative in addition to conventional photoprotection.
Contrasting Photo-physiological Responses of the Haptophyte Phaeocystis Antarctica and the Diatom Pseudonitzschia sp. in the Ross Sea (Antarctica)

The Antarctic is a unique environment in which substantial variations in irradiance occur over a number of time scales, and as a result phytoplankton need to acclimate and adapt to these changes. We conducted field and laboratory manipulations in the Ross Sea, Antarctica to examine photophysiological differences between Phaeocystis antarctica and Pseudonitzschia sp. a diatom that commonly occurrs in the Ross Sea, since these are the two functional groups that dominate abundance and productivity. Both exhibited reduced quantum yields due to high irradiances. P. antarctica , a haptophyte, displays a distinct photophysiological response to irradiance when compared to diatoms. P. antarctica showed a rapid recovery from high light exposure, as indicated by the rapid return to initial, high quantum yields, in contrast to diatoms, which responded more slowly. Absorption cross sections were high in both forms, but those in P. antarctica were significantly higher. Both organisms recovered within 24 h to initial quantum yields, suggesting that high irradiance exposure does not have a permanent effect on these organisms. Among all micronutrient additions (iron, cobalt, zinc and vitamin B 12 ), only iron additions resulted in rapid impacts on quantum yields. Iron limitation also can result in reduced photosynthetic efficiency. Understanding these photophysiologial responses and the impact of oceanographic conditions provides constraints on modeling efforts of photosynthesis and primary productivity in the Antarctic.
Crystallites of α -sexithiophene in bilayer small molecule organic solar cells double efficiency

Recent efforts in research and development of small molecule based organic solar cells have led to power conversion efficiencies exceeding 10%. Understanding the incorporated interfaces in these devices is an utterly important parameter for their improvement. Here we investigate the influence of α-sexithiophene (α-6T) nanostructures on the performance parameters of α-6T/C60 inverted bilayer solar cells. By in situ controlled growth, crystalline α-6T nanostructures are formed in the devices and a correlation between the morphology of the structures and the device performance is presented. Under certain, well-defined circumstances, we observe an efficiency increase of around 100% when implementing crystalline nanostructures.
RSS Based Location technique with the unknown transmit power and PLE using dimension reduction

Localization of mobile station (MS) has now gained considerable attention. Since the transmit power and path loss exponent (PLE) are two critical parameters in received signal strength (RSS) localization technique, many RSS based location methods considering the case that both of the transmit power and PLE are unknown have been proposed in the literature. However, one of major problems for these methods is computational complexity. Currently, MSs usually have insufficient power to afford the high computational burden. In order to meet the actual situation, the balance between positioning accuracy and computational complexity is required. This paper proposes a novel RSS based location method to reduce the computational complexity using dimension reduction technique. Simulations show that the proposed method can provide similar performance as the existing four-dimensional search methods whereas the computational burden of the proposed method is much less.
The effect of wealth and real income on wildlife consumption among native Amazonians in Bolivia: estimates of annual trends with longitudinal household data (2002–2006)

Over the last decades, native Amazonians have put increasing pressure on animal wildlife owing to growth in demand. Across societies, household monetary income and wealth shape food consumption; hence, so it is natural to ask what effect might these variables have on the demand for wildlife consumption among native Amazonians, particularly as they gain a stronger foothold in the market economy and increasing de jure stewardship over their territories. Prior estimates of the effects of household monetary income and household wealth on wildlife consumption among native Amazonians have relied on cross‐sectional data and produced unclear results. The goal of this research was to improve the precision of previous estimates by drawing on a larger sample and on longitudinal data. The analysis draws on a dataset composed of five consecutive annual surveys (2002–2006, inclusive) from 324 households in a native Amazonian society of foragers and farmers in Bolivia (Tsimane'). Multiple regression analysis is used to estimate the association between wildlife consumption and monetary income and wealth. Wildlife consumption bore a positive association with the level of household wealth and no significant association with household monetary income. Among Tsimane', the main internal threat to wildlife conservation in the short run will likely arise from increases in wealth, probably from the enhanced capacity that selected physical assets (e.g. guns) have in the capture of animal wildlife.
Carbon Stocks in Organic Coffee Systems in Chiapas, Mexico

Agroforestry systems contribute to the maintenance of ecosystem functions, especially agrisilvicultural systems such as shade coffee systems. However, the role of organic crops to store carbon has been scarcely investigated. This study aimed to quantify carbon stocks in organic polyculture coffee plantations, non-organic polyculture plantations, and organic Inga spp. -shaded coffee systems in northern Chiapas, Mexico. Vegetation inventories were carried out in 1,000 and 100 m 2 circular plots from six agroforestry communities. Carbon stocks were estimated from living biomass and roots through allometric formulas; dead biomass and soil organic matter (0- 0.3 m- in depth) were collected, dried, weighted and processed for laboratory analysis. Firstly, results showed that living biomass contributed about 30% of total carbon; soil organic carbon particularly contributed between 56 and 70%; while dead organic matter represented between 3 and 5% of total carbon in the system. Organic polyculture coffee plantations stored significantly more carbon in soil (0.1-0.3 m in depth) and tree biomass than non-organic polyculture coffee plantations. These stocks were intermediate in organic Inga spp. - shaded coffee system. Secondly, dead organic matter was statistically similar between systems. Thus, organic polyculture coffee plantations, non-organic polyculture, and organic Inga spp. -shade system stored 194.7, 134.9, and 154.3 Mg C ha -1 of total carbon, respectively. In the same order, these systems stored in live aboveground biomass 57.5, 53.0, and 46.9 Mg C ha -1 , respectively. Dead organic matter had similar amounts of C stored in the three studied systems (6.3 Mg C ha -1 ). The amounts of total carbon stocks in organic coffee were higher than those reported for others in coffee plantations in Central America and, particularly, similar to some dry and semi-humid forests and other agrisilvicultural systems in Mexico. The results highlight the importance of coffee, especially organic coffee to provide the environmental function of carbon sequestration.
