Volatility Modeling of Monthly Stock Returns In Nigeria Using Garch Model

Modeling volatility is an important element in pricing equity, risk management and portfolio management. Also modeling volatility will improve the usefulness of stock prices as a signal about the intrinsic value of securities, thereby, making it easier for firms to raise fund in the market. Therefore this study, study the nature and behavior of Stock Returns Volatility modeling of Nigerian for the periods of 324 months. The results ARCH effect (α1) is at statistically significant level. This indicates that news about volatility from the previous t periods has an explanatory power on current volatility. GARCH (1,1) model is highly persists. Indicate evidence of volatility clustering in the NSE returns series. And the results of the GJR-GARCH (1,1) model shows the existence of leverage effects in the series. Finally, the parameters α0 and α1 are greater than 0, and β1 is positive. Thus, the GARCH (1,1) seems quite good for explaining the behavior of stock returns volatility in Nigeria. Overall results from this study provide evidence to show volatility persistence, fat-Tail distribution, and leverage effects for the Nigeria stock returns.
Production of Stingless Bees (Trigona sp.) Propolis in Various Bee Hives Design

ABSTRACT: Trigona sp. is a group of stingless bees that live socially and in colony at the trunk of trees or woods, bamboo hole, sugar palm stalk and in soil hole. Variation in the habitat causes these bees colonies cannot be well-grown and reduce the propolis production. The aim of the research was to determine the production of stingless bees (Trigona sp.) propolis in various bee hives design. This research was started from September to October 2014 in Papak, Genggelang Village District of Gangga, North Lombok Regency West Nusa Tenggara Province. Material of the research was stingless bees (Trigona sp.) as much as 25 colonies taken from sugar palm stalks. Transfer of stingless bees colonies from the stalks to 5 bee hives design (35 x 17.5 x 13.5 cm; 35 x 20 x 15.5 cm; 35 x 20 x 17.5 cm; 37.5 x 20 x 20 cm; 40 x 20 x 20 cm) was performed at night and placed on the nest for about 2 months of the beekeeping process. The research result showed that production of stingless bees (Trigona sp.) propolis in various bee hives design are 20.40 ± 2.07 g; 19.00 ± 2.92 g; 30.80 ± 14.62 g; 21.80 ± 6.30 g and 18.20 ± 7.29 g respectively and did not significantly different (P>0.05). Production of stingless bees (Trigona sp.) propolis is not affected by the bee hives design but affected by the productivity of bee queen, population of workers bee, colony size of bees, activity exit and entrance hives of workers bee. It can be concluded that design 35 x 20 x 17.5 cm resulting higher production of propolis than the other design. Keywords: Stingless bees of Trigona sp. , production of propolis, bee hives design

Variance components estimation for type traits in Slovenian Brown Swiss cattle

The objective of this study was to estimate genetic parameters for 39 (26 official and 13 new) scored type traits in Slovenian Brown Swiss cattle. Data set included records of 35 386 Brown Swiss cows scored from 2000 to 2011 using method ‘System 97’. The studied type traits were scored on scale from 1 to 9 (29 traits), measured by stick or tape (five traits) or expressed in points from 60 to 90 (five traits). Multiple-trait analyses based on three models were used for estimates of genetic parameters. Fixed class effects in the models were: classifier and year of scoring interaction, calving season, and time from calving to scoring. Body condition score effect was additionally fitted as linear regression in the second model. The third model included time after milking as fixed class effect instead of condition. Direct additive genetic effect and herd were used in the models as random effects. Estimated heritabilities ranged from 0.13 to 0.46 for frame and from 0.03 to 0.22 for form traits. Low to intermediate heritabilities (from 0.10 to 0.25) were estimated for mammary system traits. The lowest heritability estimates, in range from 0.04 to 0.13, were obtained for foot and leg traits. The variance ratio for herd covered between 0.02 and 0.26 of phenotypic variation. Genetic correlations among type traits ranged from −0.41 between rear legs side view and legs overall to 0.99 between rump height measured by tape and rump height linearly scored for frame traits. High genetic correlations were estimated for the following pairs of traits: rump width measured and rump width linearly scored (0.92), central ligament and central ligament redefined (0.97), body depth measured and body depth linearly scored (0.86). Phenotypic correlations between pairs of traits were similar in direction but smaller in magnitude in comparison to genetic correlations. Measured type traits should be replaced with the scored one since genetic correlations between them were high. The replacement will lead to the same efficient but cheaper scoring system.
The aggregative response of common murres and Atlantic puffins to schools of capelin

I studied the aggregative responses of Common Murres and Atlantic Puffins to schools of capelin during three summers (1982-1984) at Witless Bay, Newfoundland, by conducting hydroacous- tic surveys for capelin in synchrony with seabird censuses. Murres and puffins foraged offshore prior to the arrival inshore of spawning schools of capelin. Both species were abundant during peak periods of capelin abundance from late June to late July, but only puffins continued to forage inshore after capelin schools dispersed in August. On individual surveys, murre and puffin flocks were significantly correlated with capelin schools at fine and coarse spatial scales. Aggregation intensity and spatial correlations peaked at measurement intervals of 2-6 km. At that scale, murres and puffins exhibited sigmoidal (Type III) aggregative responses to capelin schools. Inflection points (thresholds) in sigmoidal aggregative response curves occurred at higher densities of capelin for murres than for puffins and foraging thresholds for both species varied daily with overall capelin abundance in Witless Bay. Murres probably foraged on denser schools of capelin than puffins because of their larger body size and associated higher food demands. The implications of differing foraging thresholds for population ecology of alcids are discussed.

Fragmented Aurora-like Emissions (FAEs) as a new type of aurora-like phenomenon

Abstract. This study analyses the observations of a new type of small-scale aurora-like feature, which is further referred to as Fragmented Aurora-like Emission(s) (FAEs). An all-sky camera captured these FAEs on three separate occasions in 2015 and 2017 at the Kjell-Henriksen Observatory near the arctic town of Longyearyben, Svalbard. A total of 305 FAE candidates were identified with varying degrees of certainty. They seem to appear in two categories – randomly occurring individual FAEs and wave-like structures with regular spacing between FAEs alongside auroral arcs. FAEs show horizontal sizes typically below 20 km, a lack of field-aligned emission extent and short lifetimes of less than a minute. Emissions were observed at the 557.7 nm line of atomic oxygen and at 673.0 nm (N2, first positive band system), but not at the 427.8 nm emission of N2+ or the 777.4 nm line of atomic oxygen. This suggests a limit to the energy of the generating mechanism. Their lack of field-aligned extent indicates a different generation mechanism than for aurora, which is caused by particle precipitation. Instead, these FAEs could be the result of excitation by thermal ionospheric electrons. FAE observations are seemingly accompanied by elevated electron temperatures between 110–120 km and increased ion temperatures at F-region altitudes. One possible explanation for this are Farley-Buneman instabilities of strong local currents. We provide an overview of the observations and discuss them as well as potential generation mechanisms in the present study.
Feedstock Supply Chain CO 2-eq Emissions A Case Study on Forest Biomass for 2 nd Generation Liquid Traffic Fuel

As a part of climate and renewable energy policies, national targets are being set for minimum shares of renewable fuels of total traffic fuel consumption. The EU is planning to introduce sustainability requirements including minimum targets for greenhouse gas (GHG) reduction to be achieved by liquid traffic biofuels. Forest residues have been gaining interest in being used as a feedstock for liquid biofuels. There are only a few comprehensive studies on GHG emissions available, therefore Metsäteho Oy undertook a case study of the feedstock supply chain GHG emissions in forest chip production. Feedstock supply chain is only a part of the entire “stump-to-wheel” production chain of liquid traffic biofuel. Nevertheless, forest residues already look promising as a feedstock for biomass-to-liquid traffic fuel in terms of GHG reduction and energy efficiency. IN T R O D U C T IO N

Laser metal deposition of Ti-6Al-4V structures: new building strategy for a decreased shape deviation and its influence on the microstructure and mechanical properties

The laser metal deposition (LMD) process is used to increase the productivity rate in the field of laser additive manufacturing. Large structural Ti-6Al-4V components can be manufactured resource efficiently with this approach. In contrast, conventional manufacturing processes machine up to 95% from the bulk material to produce parts for the aerospace industry, as described by Peters et al., 2003. Compared to the powder bed based additive manufacturing the LMD process generates a local material deposition by feeding the powder directly to the substrate. On top of the surface, the laser beam will liquefy the additional material. Consequently a single track is deposited, which can be extended to a surface or 3D-structures. To qualify the LMD process for an economic industrial use, it is necessary to understand the physical phenomena during the building process. Especially for high wall structures, the thermal boundaries vary with the building height and therefore the process lacks in reproducibility and quality . In this paper, a new approach of adapted process parameters to the thermal conditions during the building process is presented. The laser power and processing speed vary for every layer until a stable building rate is achieved. The aim is to narrow the geometric tolerances of the additive manufactured structures. In addition, the influence of the building strategy on the resulting microstructure is determined.
Flood inundation damage estimation model for the Bago basin, Myanmar

Occurrence of floods is a natural phenomenon all over the world and with the increase in population and human activity in the flood plains, flood damages represent an increasing hazard in many countries. Myanmar is vulnerable to floods multiple times a year. These events cause substantial losses, both structural and socioeconomical. In this research we are developing a hydrological model WEB-DHM (Water and Energy Budgetbased Distributed Hydrological Model) coupled with RRI (Rainfall-RunoffInundation model). By developing a relationship between inundation depth and flood damage, using economical indices, the flood damage loss reduction will be estimated.
Impact of a Tapered Design in the Performance of Diffusion Flame Reactors

Several research projects developed processes for precise nanoparticle positioning with high production rates. Among the gas phase manipulation strategies, the study of the inertial properties received special attention for the fabrication of nanostructured systems. In particular, aerodynamic focusing technique has allowed particles concentration onto a single streamline, improving collimated particle beam formation and opening new perspectives for nanoparticles production in the gas phase. In this paper, the influence of the reactor design was investigated, particularly in respect to the gas phase characteristics, aiming to improve the nanoparticles focusing. It was observed that a concentrated beam can be obtained in the new tapered reactor design without significantly affect the production rate and temperature profile. In addition, the coupling of aerodynamic lenses to the tapered reactor was also investigated, showing that the flow can be better focused at the cost of an increase in the average temperature and pressure drop.

Morphological and Molecular Differentiation between Rheophilic Barbels Barbus spp. (Cyprinidae) from Headwaters at the Divide between Drainage Areas of the Danube, Vardar and Struma Rivers, Central Balkans

External morphology and cytochrome b structure of rheophilic barbels from headwaters of the Pčinja, Vrla (Barbus balcanicus) and Dragovištica (B. strumicae) Rivers in Southern Serbia at the watershed between the drainage areas of the Vardar (Axios), Danube and Struma (Strymon) Rivers, respectively, were examined. Barbel specimens from the Pčinja River were clearly different from both congeners from the other two rivers in the shape of the head and the length of the caudal fin. They were closer in external morphology to B. strumicae from the Dragovištica River as compared to B. balcanicus from the Vrla River. On the contrary, their relationship inferred from the structure of cytohrome b revealed closer relationship between B. balcanicus and the rheophilic barbel from the Pčinja River. Despite of the differentiation in morphology found between specimens of the rheophilic barbel, the divergence between them was insufficient for sound taxonomic inferences. Their phylogenetic relationships shed some new light on their evolutionary history in the study area.
Heuristic Goal Recognition in Incomplete Domain Models

Recent approaches to goal recognition have progressively re-laxed the assumptions about the amount and correctness of domain knowledge and available observations, yielding accurate and efﬁcient algorithms. These approaches, however, assume completeness and correctness of the domain theory against which their algorithms match the sequence of observations: this is too strong for most real-world domains. In this dissertation, we develop heuristic goal recognition techniques that are capable of recognizing goals using incomplete (and possibly incorrect) domain theories using new notions of planning landmarks.
Thermal stability and subunit composition of muscle and skin type I collagens from skipjack.

Skipjack Euthynnus pelamis is one of the species of warm-blooded fishes and its true dark muscle is often 10°C warmer than the surrounding water. In this study, we have isolated soluble Type I collagens from the true dark muscle, ordinary muscle, and skin of skipjack in order to make a comparison on their thermal stability and subunit composition. The denaturation temperature of dark muscle collagen, 33.0°C, was found to be higher than those of ordinary muscle and skin collagens by 0.2°C and 2.0°C, respectively. This was explained by the high degree of proline hydroxylation, that is, the high content of hydroxyproline in the dark muscle collagen, when compared to the other two collagens. On the other hand, the chromatographic and electrophoretic analyses of these collagens showed a tissue-specific existence of two molecular forms; an (α1)2a2 heterotrimer for dark and ordinary muscles and an α1α2α3 heterotrimer for skin.

Unbalanced phase voltages in electricity networks prevent efficient and stable delivery of power and energy services from utility companies to end-users, and vice versa. While variations in voltage magnitude and power loss have been studied extensively, little attention has been paid to the development of linearized expressions to account for the variation in voltage unbalance. Using a standard definition of the voltage unbalance factor (VUF), this study is the first, to the best knowledge of the authors, in which a VUF sensitivity matrix is mathematically developed and analyzed with respect to variations in 3-phase (3-ph) voltages and, consequently, 3-ph unbalanced load demand. To demonstrate its utility, we performed simulation case studies and compared the estimates made using the matrix to those from a power flow calculation algorithm. The VUF sensitivity matrix is expected to have a variety of practical applications for power systems, such as optimal scheduling and real-time control, which enables improvement in network power quality.
VisualHFSM 5: recent improvements in programming robots with automata in JdeRobot

—A visual programming tool, named VisualHFSM, has been improved in the JdeRobot robotics software framework. This tool provides Hierarchical Finite State Machines to program robot behaviors. The particular automata is designed visually, with nodes for the states, links for the transitions and speciﬁc source code on them. It automatically generates a C++ or a Python JdeRobot component that connects to the drivers and implements the automata. It uses multithreaded templates for that. Such component dynamically shows the current state of the automata while running. This tool speeds up the development time of robot behaviors, reducing the code that has to be created from scratch for new behaviors. VisualHFSM has been experimentally validated creating several autonomous behaviors for drones.
Loop coproducts

In this paper we show that if $A$ is a Poisson algebra equipped with a set of maps $\Delta^{(i)}_\la:A \to A^{\otimes N}$ satisfying suitable conditions, then the images of the Casimir functions of $A$ under the maps $\Delta^{(i)}_\la$ (that we call"loop coproducts") are in involution. Rational, trigonometric and elliptic Gaudin models can be recovered as particular cases of this result, and we show that the same happens for the integrable (or partially integrable) models that can be obtained through the so called coproduct method. On the other hand, this loop coproduct approach is potentially much more general, and could allow the generalization of the Gaudin algebras from the Lie-Poisson to the Poisson algebras context and, hopefully, the definition of new integrable models.
