Subjects: subject: Law
subject: FOS: Law

description: This thesis analyses renewable energy legislative measures of South Australia against those of the other jurisdictions that form the National Electricity Market – Queensland, New South Wales, the Australian Capital Territory, Victoria and Tasmania. The legislative measures analysed are renewable energy target schemes, feed-in tariff schemes, measures that promote research in, and the development and commercialisation of, renewable energy technologies, and subordinate tools that promote ‘grass roots’ action on renewable energy. The key findings of this thesis show the National Electricity Market jurisdictions have played, and continue to play, a valuable role in promoting the increased uptake of renewable energy.

description: We introduce an innovative three-dimensional spectral approach (three band parameter space with polyhedrons) that can be used for both qualitative and quantitative analyses improving the characterization of surface heterogeneity of (4) Vesta. It is an advanced and more robust methodology compared to the standard two-dimensional spectral approach (two band parameter space). The Dawn Framing Camera (FC) color data obtained during High Altitude Mapping Orbit (resolution ~ 60 m/pixel) is used. The main focus is on the howardite-eucrite-diogenite (HED) lithologies containing carbonaceous chondritic material, olivine, and impact-melt. The archived spectra of HEDs and their mixtures, from RELAB, HOSERLab and USGS databases as well as our laboratory-measured spectra are used for this study. Three-dimensional convex polyhedrons are defined using computed band parameter values of laboratory spectra. Polyhedrons based on the parameters of Band Tilt (R0.92μm/R0.96μm), Mid Ratio ((R0.75μm/R0.83μm)/(R0.83μm/R0.92μm)) and reflectance at 0.55 μm (R0.55μm) are chosen for the present analysis. An algorithm in IDL programming language is employed to assign FC data points to the respective polyhedrons. The Arruntia region in the northern hemisphere of Vesta is selected for a case study because of its geological and mineralogical importance. We observe that this region is eucrite-dominated howarditic in composition. The extent of olivine-rich exposures within an area of 2.5 crater radii is ~ 12% larger than the previous finding (Thangjam et al., 2014). Lithologies of nearly pure CM2-chondrite, olivine, glass, and diogenite are not found in this region. Our spectral approach can be extended to the entire Vestan surface to study the heterogeneous surface composition and its geology.

description: This thesis presents the design, development and subsequent experimental evaluation of a miniature parallel mechanism which enhances the mobility of instruments for robotically assisted endonasal surgery. The design requirements for an endonasal surgery robot are investigated, leading to the development of a full scale prototype wrist mechanism. This mechanism is designed to be inserted through the nose, requiring compactness in both the mechanism’s construction as well as its motion characteristics. A visual tracking system was then used to verify that the mechanism provides the required range of motion.

aluminium-doped p+ regions on the rear made from screen-printed paste and acting as emitter or back surface field,
respectively. We investigate near-industrial large-area n+np+ rear junction and n+pp+ front junction cells and discuss
three cell concepts with different rear side structures: (i) For solar cells with a full-area non-passivated Al-p+ rear, we
demonstrate similar performances on n- and p-type float-zone Si material with efficiencies of 18.6 % and 18.4 %,
respectively. For our best n-type cell with a rear Al emitter coverage of 100 %, we have achieved a record-high
efficiency of 19.3 %. (ii) For solar cells with a full-area and surface-passivated Al-p+ rear, we have obtained an
increase in the open-circuit voltage of 10 mV and in the short-circuit current density of 1.5 mA/cm2. (iii) For solar
cells with laser-fired Al-p+ points in the passivated rear Si surface, we have reached an efficiency of 19.6 % for a ptype
LFC cell.

description: The outer boundaries of the growing colonies of bacteria or growing skin tissues or even single eukaryotic cells develop finger-like structures. These structures help bacterial colonies in infecting the virgin tissues in a shorter time. Fingers on single-cells assist them in achieving motility to survive. Understanding the fingers on these systems is thus necessary to understand their evolution. But, these are complex to solve. In this thesis, we use simple fluid mechanical concepts to develop mathematical models for such biological systems and find the conditions under which they form fingers on their boundaries.

description: 25th European Photovoltaic Solar Energy Conference and Exhibition / 5th World Conference on Photovoltaic Energy Conversion, 6-10 September 2010, Valencia, Spain; 5000-5006
description: In this paper three decentralised voltage control approaches, using reactive power supplied by photovoltaic
(PV) inverters, are compared with respect to their capabilities to limit the voltage rise within a balanced low voltage system
with a high level of PV penetration. Two of these voltage control approaches fall into the static reactive power supply
methods category, according to the pending German guideline for generators connected to low voltage distribution networks.
The third approach uses a dynamic reactive power controller to adjust the reactive power output of the PV inverter in order
to maintain a preset voltage limitation. The simulation results show, that both static reactive power supply methods are
capable of reducing voltage magnitudes within a low voltage network and hence can contribute to increasing the distribution
systems absorption capacity for installed PV systems. However an even higher absorption capacity can be achieved by
applying the dynamic voltage control approach. Compared to no reactive power provision, the absorption capacity of the low
voltage network for PV systems could be more than doubled by using the dynamic voltage control approach.

description: We model the dust and free-free continuum emission in the high-mass star-forming region Sagittarius B2 in order to reconstruct the three-dimensional density and dust temperature distribution, as a crucial input to follow-up studies of the gas velocity field and molecular abundances. We employ the three-dimensional radiative transfer program RADMC-3D to calculate the dust temperature self-consistently, provided a given initial density distribution. This density distribution of the entire cloud complex is then recursively reconstructed based on available continuum maps, including both single-dish and high-resolution interferometric maps covering a wide frequency range (40 GHz - 4 THz). The model covers spatial scales from 45 pc down to 100 au, i.e. a spatial dynamic range of 10^5. We find that the density distribution of Sagittarius B2 can be reasonably well fitted by applying a superposition of spherical cores with Plummer-like density profiles. In order to reproduce the spectral energy distribution, we position Sgr B2(N) along the line of sight behind the plane containing Sgr B2(M). We find that the entire cloud complex comprises a total gas mass of 8.0 x 10^6 Msun within a diameter of 45 pc, corresponding to an averaged gas density of 170 Msun/pc^3. We estimate stellar masses of 2400 Msun and 20700 Msun and luminosities of 1.8 x 10^6 Lsun and 1.2 x 10^7 Lsun for Sgr B2(N) and Sgr B2(M), respectively. We report H_2 column densities of 2.9 x 10^24 cm^-2 for Sgr B2(N) and 2.5 x 10^24 cm^-2 for Sgr B2(M) in a 40" beam. For Sgr B2(S), we derive a stellar mass of 1100 Msun, a luminosity of 6.6 x 10^5 Lsun and a H_2 column density of 2.2 x 10^24 cm^-2 in a 40" beam. We calculate a star formation efficiency of 5% for Sgr B2(N) and 50% for Sgr B2(M), indicating that most of the gas content in Sgr B2(M) has already been converted to stars or dispersed.

description: Fluorine doped tin oxide (SnO2: F) films have been widely used as Transparent Conductive Oxides
(TCO) film for Si thin film solar cells, and recently we have developed SnO2: F TCOs with “double-texture (W-texture)” on
their surface, named HU-TCO. One of the advantages of HU-TCO is high haze value thorough the whole optical region
where a-Si: H and μc-Si: H solar cells are sensitive. An improvement of spectral response of μc-Si: H solar cells fabricated
on HU-TCOs were shown especially in longer wavelength region. “W-texture” TCO has a combination of 300-500nm high
and over 1μm wide hills those are covered with submicron-size pyramidal texture that leads to high haze value in a wide
range, high transparency and low sheet resistance. In the previous works we studied how the size of large hills affected the
light scattering of TCOs and spectral response of μc-Si: H cells fabricated on them. In this work we have studied the size
effect of surface submicron-size pyramidal texture on the light scattering of HU-TCOs. The surface texture bigger than
100nm were useful to eliminate fluctuation of QE in a-Si: H solar cell and enhancing photo current because of the index
matching between TCO and a-Si. However, the surface texture smaller than 100nm was not enough for eliminate
fluctuation of QE, even though HU-TCOs have large hills over 0.8μm in width.

description: GFRP composites provides tremendous benefits when considered as construction material for building structures and its constituent floor system. Such benefits includes lower structural self-weight and increased durability. Recently a new innovative GFRP sandwich panel has been proposed as alternative to conventional concrete slab. The GFRP sandwich panel is lightweight and relatively stiff. However due to its lightweight and low damping properties, vibration serviceability problems may arise. Hence, this research was undertaken to explore the vibration serviceability performance of the bespoke GFRP sandwich panel floors under human excitation. The results show that traditional forms of assessment are not applicable and new methods are proposed.

description: Because the amount of power generation from PV system is subject to erratic natural phenomena, the
supply and demand adjustment in electric power will be difficult when PV systems are interconnected with power
systems in large quantities. Therefore, the importance of forecasting the amount of PV power generation, i.e., solar
irradiation forecast, is increasing. In this paper, we propose a new forecasting method using statistical pattern
recognition in order to achieve accurate forecast of solar irradiation. We conducted an improvement of forecast
accuracy by modifying data structure for input. Furthermore, we also investigate the effect of the introduction of the
meteorological data around the targeted point and the cloudiness of numerical prediction data in Meso-Scale Model.
Tunneling and Josephson effects in odd-frequency superconductor junctions: A study on multi-channel Kondo chain

description: Junction systems of odd-frequency (OF) superconductors are investigated based on a mean-field Hamiltonian formalism. One-dimensional two-channel Kondo lattice (TCKL) is taken as a concrete example of OF superconductors. Properties of normal and Andreev reflections are examined in a normal metal/superconductor junction. Unlike conventional superconductors, normal reflection is always present due to the normal self energy that necessarily appears in the present OF pairing state. The conductance reflects the difference between repulsive and attractive potentials located at the interface, which is in contrast with the preexisting superconducting junctions. Josephson junction is also constructed by connecting TCKL with the other types of superconductors. The results can be understood from symmetry of the induced Cooper pairs at the edge in the presence of spin/orbital symmetry breaking. It has also been demonstrated that the symmetry argument for Cooper pairs is useful in explaining Meissner response in bulk.

description: The deposition of homogenous μc-Si layers is crucial for the production of high efficiency a-Si/μc-Si
tandem modules. The uniformity of the layers is strongly influenced by the process parameters, e.g. pressure or
electrode gap, but can also be influenced by the hardware configuration. The deposition rate uniformity and the effect
on the crystallinity distribution of the microcrystalline films were studied. The impact of these hardware adjustments
is also seen in the distribution of the TJ IV parameters. While the standard hardware shows fully amorphous tandem
cells (high Voc, low CE) in the corners when the cells are microcrystalline in the center, a nearly uniform distribution
is achieved with the adjusted hardware.

description: Ion implantation is the technique of choice for introducing dopant species into semiconductors in
CMOS devices. In photovoltaics ion implantation could be an interesting alternative to tube furnace diffusion
processes. However, one issue of major importance concerning ion implantation always is the removal of the damage
introduced by the implantation process as solar cells always require a defect free, perfectly passivated surface. Thus
the surface quality and passivation of boron and phosphorus implanted samples was investigated within this work. It
has been found that after an appropriate annealing the introduced damage of both boron and phosphorus implanted
surfaces can be completely removed. Very low saturation current densities of <25 fA/cm2 could be achieved for both
boron and phosphorus implanted surfaces after passivation with Al2O3 and SiO2 respectively. On n-type back junction
solar cells were both the phosphorus FSF as well as the boron emitter have been realized by ion implantation
conversion efficiencies up to 19.4% could be achieved.

description: We consider two coupled populations of leaky integrate-and-fire neurons. Depending on the coupling strength, mean fields generated by these populations can have incommensurate frequencies, or become frequency locked. In the observed 2:1 locking state of the mean fields, individual neurons in one population are asynchronous with the mean fields, while in another populations they have the same frequency as the mean field. These synchronous neurons form a chimera state, where part of them build a fully synchronized cluster, while other remain scattered. We explain this chimera as a marginal one, caused by a self-organized neutral dynamics of the effective circle map.

description: The exactly controlled wet-chemical etch-back of diffusion profiles can shift the efficiency limit of the
widely used screen printing process to higher values. In conjunction with an inkjet or screen printing masking step,
the cost effective production of selective emitter solar cells is possible. We present the development of our etch-back
process using Cz-Si and mc-Si wafers. Emitter saturation current densities of etch-back emitters are lower compared
to directly POCl3-diffused samples with the same sheet resistance. Negative effects of the etch-back process on
reflection properties are negligible if less than 90 nm are removed from the surface. Grain boundaries of mc-Si
wafers may be etched faster than the rest of the wafer. A screen printed 5 inch Cz-Si selective emitter solar cell with
full area Al BSF reached an efficiency of 19.0%. The same process was applied to n-type Cz-Si wafers with a
selective front surface field (FSF) and a full area screen printed Al emitter. An efficiency of 18.5% on 6 inch n-type
Cz solar cells could be reached in a first test. This emphasizes the highly effective FSF and makes the process
attractive for possible industrial production, since no boron-oxygen degradation occurs in n-type silicon.

description: Aims. We report a study of the global properties of some embedded clusters placed in the fourth quadrant of the Milky Way to clarify some issues related with their location into the Galaxy and their stellar formation processes. Methods. We performed BVI photometric observations in the region of DBS 77, 78, 102, 160, and 161 clusters and infrared spectroscopy in DBS 77 region. They were complemented with JHK data from VVV survey combined with 2MASS catalogue, and used mid-infrared information from GLIMPSE catalogue. We also searched for HI data from SGPS and PMN radio surveys, and previous spectroscopic stellar classification. The spectroscopic and photometric information allowed us to estimate the spectral classification of the brightest stars of each studied region. On the other hand, we used the radio data to investigate the interstellar material parameters and the continuum sources probably associated with the respective stellar components. Results. We estimated the basic physical parameters of the clusters (reddening, distance, age, and initial mass function). We searched for HII regions located near to the studied clusters and we analyzed the possible link between them. In the particular case of DBS 160-161 clusters, we identified the HI bubble B332.5-0.1-42 located around them. We found that the mechanical energy injected to the interstellar medium by the more massive stars of this couple of clusters was enough to generate the bubble.

description: One of the main challenges to the dissemination of photovoltaic systems is the obtaining of acceptable
forecasts for the solar irradiation. An adequate forecast of solar irradiation can improve the assessment of the output
of a photovoltaic system before hand, allowing a stable integration of such systems in the public electricity grid.
Considering that, the objective of this study is to forecast the solar irradiation with an artificial neural network, and
to investigate potential gains in the accuracy of the forecasts when using numerically predicted cloudiness data in
the input of such artificial neural network. The numerically predicted cloudiness was generated by the grid-point
value forecast system of the Japan Meteorological Agency. The Forecasts of solar irradiation were done for Tokyo
from June of 2008 to June of 2009. The results showed that the use of cloudiness in the input of an artificial neural
network yield meaningful improvements in the accuracy of the forecasts of solar irradiation. For example, the root
mean square error of annual forecasts of solar irradiation decreased from 0.085 kWh/m2 to 0.073 kWh/m2, around
14%; for the mean relative variance error the improvement was even higher varying from 0.110 to 0.081, around
26%.

description: We introduce new three-dimensional topological phases of two-band models using the Pontryagin-Thom construction. In symmetry class A these are the infinitely many Hopf-Chern topological insulators, which are hybrids of layered Chern insulators and the Hopf insulator. In symmetry class C, there is a $\mathbb{Z}_2$-classification with the non-trivial topological phase, the Hopf superconductor, being realized by a construction that doubles the usual Hopf insulator in momentum space. For these new topological phases we investigate the energy spectrum in the presence of a boundary and find gapless surface modes, confirming the validity of the bulk-boundary correspondence.

description: The Research Group »Fuzzy Borders« investigates the diverse qualities of borders and boundaries in antiquity as well as corpuses of knowledge which are effective in shaping the spatial design of borders. Its primary focus is on border zones and on the kind of indistinct, fuzzy borderlines which become visible and describable only against the background of concrete forms of delimitation. Our research activities are divided into two project groups, the first concerned with the formation and linear definition of borders, for example in the form of town walls, the second concerned with their dissolution and with border zones. The group is affiliated through Silke Müth and Peter Schneider with the DFG network of younger researchers entitled »Fokus Fortifikation,« which is preoccupied with town walls and fortifications in the eastern Mediterranean region. Incorporated into Research Area B (»Mechanisms of Control and Social Spaces«), the project is designed to provide a foundation for an improved understanding of the organization of social groups and of states through an examination of their external borders. We are also interested, finally, in instances where definitions of external borders are renounced altogether and states are organized from the center toward outer margins, for example, with the ›edge‹ of a given territory remaining undefined. Investigated on the basis of archaeological finds and textual sources are transboundary social relationships, whose significance for the transfer of knowledge currently forms the substance of discussions within our research group.

description: Iran’s proper status in the development of science and knowledge at the international level represents the institutionalized decision making system in this sector of the country. Besides, Iran’s strategic documents always emphasize on the formation of a place for the country’s knowledge and technology. Regarding to the development of technologies and IT infrastructures, this paper focuses the technological functions of scientific information management in the research and resource management value chain and analyzes the facilitation of the research services enhancement in the country. The approach of the paper is almost qualitative. At first, we identify the scientific and technological information value chain and its stockholders, applications, requirements, based on the previous documents, and international documents including goals and strategies, plans and actions. Then, we recognize the classification, and the definition of IT based on service systems. Finally, we present the IT functionality of scientific information management and research value chain based on the stockholders as a conceptual model.

description: Due to medical researchers need for updated and valid scientific findings in their research area, it is important to evaluate medical journals. On the other hand, researchers are looking for prestigious journals to publish their articles in their field of activity. Because much of the medical journals in Iran published by Universities of Medical Sciences, this study aimed to evaluate Iranian Medical Sciences Universities' research journals in Google Scholar citation database between 2010-2014, with emphasis on both scientific impacts: The Journal Hirsch index and Journal Impact factor. In order to collect data the researchers used publish or perish, which is a citation analysis software. Data were analyzed by descriptive statistics and Spearman correlation test using Microsoft Excel and SPSS16. The results showed that a total of 38,717 articles from 130 surveyed journals in the period of study was indexed in Google Scholar and these articles had received 61,938 citations, i.e. 1.6 citations per article. Total average of Hirsch index in study population was 7 and total average of journals impact factor was 1.31. Spearman correlation test results showed that the journal language and number of journals articles have a significant positive correlation with the number of received citations, journal Hirsch index and journal impact factor. The relationship between journal impact factor and Hirsch index was significant too. It seems that due to the high correlation between journal impact factor and Hirsch index, these two indicators can be used as complementary elements in evaluating journals.

description: Purpose: Investigated the information need and information seeking behavior in the Iran manufacturing industry.\n \nMethod/Design: To gain a deep understanding of the issue, we used grounded theory approach. 25 manufacturing firms operating in the Isfahan Science Technology Park were selected purposefully.  Data was obtained from 20-30 minute semi-structured interview with all 25 companies’ managers.\n \nFindings: In emerged that the companies` information needs are variant based on their fields of work and by the environment. Furthermore, companies use three sources (persons, organizations, consultants) to obtain information. These resources include: market resources (experience and knowledge, market observation, exhibition and advertisements, other organizations, and communications); scientific resources (publications, imitation, experts and specialists knowledge and experience) and other resources (internet, media, and customers). Companies’ information seeking behavior ranges from easy to stringent behavior
A Method for FIDO Management trough Biometric Technology in IOT

description: Internet of Things (IOT) is a newly developed concept in the world of technology and communication which provides the ability to transfer technological information to everything, including human, animals, or objects, through communication networks such as internet or intranet. Biometric technology offers various applications. The main objective is to provide an appropriate alternative for control systems with traditional access. It is also utilized for personal protection or corporate finance. Simultaneous application of Biometric technology and Fast Identity Online (FIDO) may advance interaction with objects and authentication of those who want to access crucial information. Furthermore, the authentication of individuals is a more accurate and faster process. Whereas in the traditional techniques, this process is much more costly and time-consuming. This article presents a new approach for utilizing biometric technology in IOT, in order to manage biometric in IOT. The results demonstrate fingerprint biometry obtains the highest priority as compared to other biometric techniques used in IOT, while it imposes the lowest implementation costs. Moreover, it provides a high level of security for the system management.
Modulators of choice overload in Google search engine

description: Nowadays, analyzing user behavior on search engines is highly regarded. Lots of options in retrieved results in the search engines, makes users to choose. Once the selection is extremely complex, people will think the simplest decision rule, they decided that not to decide and select. Psychologists know this situation the consequence of "choice overload". Bons (2008) believes that choice overload is the ability of process the information by the people to select. In simpler terms, dealing with a lot of information, lead to the negative results. This study has been done with the goal to identify modulators of Google search engine. The present study is a survey and an applied research. Using stratified random non-relativistic sampling, 72 MS and PhD students of faculty of Psychology and Educational Sciences and Engineering of Ferdowsi University were selected as a sample. The tools used for collecting data were standard questionnaire (maximizing scale by Schwartz et al 2002) and HCI browser. The results showed that regardless of the personality types (maximizer and satisfier) and only by regarding of the type of search, you cannot say a definitive statement about choice overload theory. Considering two variables of personality and search type, a significant difference between satisfaction of two types personality from the number of retrieved results were observed.This means that maximizers are, in both special and general search, more satisfied from small results than large results (choice overload). But satisfiers, in special search, the number of retrieved results had no effect on the satisfaction of them (the non-occurrence of choice overload). Also in satisfiers, in general search results, there was a significant difference between satisfaction from the small and large retrieved results. However, according to their personality and serendipity theory, with increasing the retrieved results, not only choice overload did not occur, but satisfaction of them was more. Hence we can the importance of two factors: the type of search and personality as modulators of choice overload. In general both personality types were satisfied with the speed of retrieve of results in Google search engine.

description: A significant amount of available information is stored in textual databases which contains a large collection of documents from different sources (such as news, articles, books, emails and web pages). The increasing visibility and importance of this class of information motivates us to work on having better automatic evaluation tools for textual resources.\n\nThe automatic summarization of text is one of the ways to prevent the waste of users’ time. The extractive text summarization consists of the extraction of the more important sentences with the purpose of shortening input text while maintaining the topics covered and the subjects discussed.\n\nIn this paper, we have tried to improve the accuracy of the extracted summaries by combining natural language processing and text mining techniques. By modifying the mentioned algorithms and sentence scoring measures, accuracy is increased as compared to the previously used techniques.\n\nPart of speech tagging is used for calculating coefficient of words’ importance. Using this approach will in turn help us with to pick the more meaningful words and phrases that will result in better accuracy of the system.\n\nGraph similarity‘s methods are used to select sentences. Changing weight of the selected sentences in each step leads to solve the redundancy problem.\n\nStandard evaluation measures such as “Precision” and “Recall” are used to evaluate results based on a Persian corpus.
