Millimeter Wave Propagation Measurements and Characteristics for 5G System

In future 5G systems, the millimeter wave (mmWave) band will be used to support a large capacity for current mobile broadband. Therefore, the radio access technology (RAT) should be made available for 5G devices to help in distinct situations, for example device-to-device communications (D2D) and multi-hops. This paper presents ultra-wideband channel measurements for millimeter wave bands at 19, 28, and 38 GHz. We used an ultra-wideband channel sounder (1 GHz bandwidth) in an indoor to outdoor (I2O) environment for non-line-of-sight (NLOS) scenarios. In an NLOS environment, there is no direct path (line of sight), and all of the contributed paths are received from different physical objects by refection propagation phenomena. Hence, in this work, a directional horn antenna (high gain) was used at the transmitter, while an omnidirectional antenna was used at the receiver to collect the radio signals from all directions. The path loss and temporal dispersion were examined based on the acquired measurement data—the 5G propagation characteristics. Two different path loss models were used, namely close-in (CI) free space reference distance and alpha-beta-gamma (ABG) models. The time dispersion parameters were provided based on a mean excess delay, a root mean square (RMS) delay spread, and a maximum excess delay. The path loss exponent for this NLOS specific environment was found to be low for all of the proposed frequencies, and the RMS delay spread values were less than 30 ns for all of the measured frequencies, and the average RMS delay spread values were 19.2, 19.3, and 20.3 ns for 19, 28, and 38 GHz frequencies, respectively. Moreover, the mean excess delay values were found also at 26.1, 25.8, and 27.3 ns for 19, 28, and 38 GHz frequencies, respectively. The propagation signal through the NLOS channel at 19, 28, and 38 GHz was strong with a low delay; it is concluded that these bands are reliable for 5G systems in short-range applications.
Qualitative Investigation of Digital Divide: Toward a Qualitative Investigation of Digital Divide: Toward a Comprehensive Framework Comprehensive Framework

The issue of digital divide has attracted many researchers for over a decade, yet the understanding of digital divide is not comprehensive. This research examines three commonly recognised orders of the digital divide, which are: economic divide, the inequality of access to ICT associated with economic conditions; access divide, the disparity of access to ICT; and capability divide, the inequality of ability in using ICT, while conceptualising a fourth divide, innovativeness divide, which is defined as the disparity of individual’s willingness to try out any new information technology. The paper presents a tentative model based on extensive literature review which was explored using qualitative method. The findings generate new insights into the relationships among those four orders of digital divide which contribute to the theoretical framework to understand the digital divide more comprehensively and provide evidence on the impact of digital divide on e-government use. Implications for theory and practice are also discussed in this paper.
Oriental Painting and Cortical Motor Activation: An EEG Oscillation Study

In EEG experiments, mu (8-14 Hz) rhythm has long been studied in relation to the observation of actions. Although it is not clear how brain oscillations relate to specific cognitive process, changes in mu rhythm are generally accepted as being related with the activation of the motor cortex (Arnstein et al 2011, Perry et al 2011). As early as 1954, Gastaut (Gastaut & Bert 1954) reported desynchronization in mu rhythm and power attenuation during observations of action. Since then, many studies on mu rhythm suppression in relation to the observation of action have flourished. Among many studies, the study showing mu rhythm changes in viewing artworks interested us most (Umilta et al 2012). In the study of Umilta et al. (2012), mu rhythm suppression was intensely evoked by the observation of Lucio Fontana’s original artworks than by the control stimuli. Fontana cut the canvas with a knife so the original artworks consist of a canvas that has been cut either once or multiple times. Similarly, in the study of Sbriscia-Fioretti et al. (2013), motor activation was detected while observing Franz Kline’s artwork. In these studies, the authors defined
Introduction to DICOM-RTV: a new standard for real-time video communication in hospitals

In order to overcome the challenges of managing real-time transfer of video, and/or audio, and associated medical metadata inside the medical theaters (e.g., operating room), a new DICOM communication service standard emerged. Its main objective is to deliver synchronized videos (potentially synchronized with their corresponding metadata) in real-time to surgeons during a surgery inside an operating room. Moreover, it allows, on one side, the transmission of real-time videos to subscribers with a quality of service comparable to the one inside the operating room, and on the other side, provides a standard that will allow the interoperability between the different medical equipment that produce/consume the media essences. This new DICOM extension is called DICOM Real-Time Video (DICOM-RTV). This paper is an introduction to this extension. It mainly presents the different challenges solved by this extension, illustrates it with relevant use cases, and provides the global architecture of the DICOM-RTV system.
SEMIDEFINITE PROGRAMMING UPPER BOUNDS FOR PACKING PROBLEMS fernando mário de oliveira filho

§1. Notation For x, y ∈ R, let x ·y = x1y1 + · · ·+xnyn denote the Euclidean inner product and write ‖x‖ = (x · x) for the norm. By Sn−1 = {x ∈ R : ‖x‖ = 1 } we denote the (n− 1)-dimensional unit sphere and by ω the surface measure on it. A spherical cap is the intersection of the unit sphere with a half-space. By B = {x ∈ R : ‖x‖ ≤ 1 } we denote the n-dimensional unit ball. A lattice Λ ⊆ R is a discrete subgroup of R, i.e., it is the set of all integer linear combinations of some vectors u1, . , un that form a basis of R. A nonzero vector x ∈ Λ is a minimal vector if it has minimum length among all nonzero vectors in Λ. The Hamming cube is the set Hn = Z2 of all n-bit words. The Hamming distance between two words is the number of bits in which they differ. The weight of a word x is the number of 1s in it and is denoted by |x|, so that the Hamming distance between x, y ∈ Hn is |x+ y| = |x− y|.
The Effect of Melt Pond Geometry on the Distribution of Solar Energy Under First‐Year Sea Ice

Sea ice plays a critical role in the climate system through its albedo, which constrains light transmission into the upper ocean. In spring and summer, light transmission through sea ice is influenced by its iconic blue melt ponds, which significantly reduce surface albedo. We show that the geometry of surface melt ponds plays an important role in the partitioning of instantaneous solar radiation under sea ice by modeling the three‐dimensional light field under ponded sea ice. We find that aggregate properties of the instantaneous sub‐ice light field, such as the enhancement of available solar energy under bare ice regions, can be described using a new parameter closely related to pond fractal geometry. We then explore the influence of pond geometry on the ecological and thermodynamic sea ice processes that depend on solar radiation.
Meteorological Climate Change effect of the Ataturk Dam in Turkey at Eastern Anatolia

In Turkey, the significant amount of energy produced obtained of hydroelectrical power stations. Water constructions such as dam’s reservoir in arid and semi-arid regions effects each other with climate and hydrology of environment. Therefore meteorological conditions have to be established and monitored at the hydroelectrical power stations. Droughts are among the most significant natural hazards that might damage human life and property under different meteorological and environmental conditions. The simplest methodology of temporal climate change assessment is the standardized precipitation index (SPI) which is used to quantify the precipitation deficit for several time scales, for example time averaging periods. The SPI is commonly used for the identification of various climate change characteristics such as the rain duration change, magnitude change, and intensity change at different standard truncation levels. The relationships between the drought duration and magnitude are provided in the form of scatter diagrams with the best straight-line fits. These are obtained for different truncation levels. Precipitation based drought description has been extended to triple-variable additionally including temperature and humidity time series. Such contours can be prepared for any base precipitation value but in this study average precipitation value is adopted as the truncation level. In this study is related to construction of the most important main project in the Southeastern Anatolia Project (GAP) area, the Ataturk Dam.

On the Nanoscale Mapping of the Mechanical and Piezoelectric Properties of Poly (L-Lactic Acid) Electrospun Nanofibers

The effect of the post-annealing process on different properties of poly (L-lactic acid) (PLLA) nanofibers has been investigated in view of their use in energy-harvesting devices. Polymeric PLLA nanofibers were prepared by using electrospinning and then were thermally treated above their glass transition. A detailed comparison between as-spun (amorphous) and annealed (semi-crystalline) samples was performed in terms of the crystallinity, morphology and mechanical as well as piezoelectric properties using a multi-technique approach combining DSC, XRD, FTIR, and AFM measurements. A significant increase in the crystallinity of PLLA nanofibers has been observed after the post-annealing process, together with a major improvement of the mechanical and piezoelectric properties.
Role of Wiener chaos expansion in modelling randomness for groundwater contamination flow

Pertinent mathematical modelling plays pivot role in making groundwater protection and reclamation policies. Uncertain parameters and several basic phenomena in almost all branches of engineering and science can be modelled efficiently with the help of Stochastic Partial Differential Equations (SPDEs) and their behaviour can be interpreted more accurately. The intent of the present study is to use an efficient numerical approach based on Wiener chaos expansion to understand the stochastic nature of variables associated with groundwater flow. First and second order moments of concentration profile are calculated and plotted graphically. Obtained results are in good aggrement with those available in existing literature.
Voting, Opportunity Costs, and Property Taxes

Owners of real estate owe property taxes to local governments, but only permanent residents are granted the right to vote. The presence non-voting property owners reduces the share of total property tax revenue remitted by resident voters, thereby lowering residents’ opportunity costs of public expenditure. Minnesota data suggest that spending on municipal services is higher as a result of the lower opportunity costs: communities with high concentrations of property value owned by non-voters spend more per resident than other communities. These results suggest that a one percent decrease in opportunity costs for voters is associated with at least a 0.50% increase in per capita property tax revenue. A policy innovation in 2001 affords the opportunity to further identify the effect on property taxes by comparing revenues before and after the change. These results suggest that a one percent increase in voter tax share is associated with a 1% decrease in per capita property tax revenue, a reduction of approximately $20 per capita at the mean. ∗Department of Economics M/C 144, UIC, 601 South Morgan Street, Room 2103, Chicago, IL 60607-7121.

Estimation of background for final states including tau leptons with the ATLAS experiment

Processes with tau leptons in a final state are essential in many experiments studying products of proton collisions. Tau lepton most often decays hadronically; therefore jets misidentified as tau leptons can be a source of a significant part of the background of these events. A part of phase space where most reconstructed taus are misidentified jets is chosen. This part of phase space can be events with Z boson decaying into two muons. These events were studied, and distributions of several variables were compared with Monte Carlo simulation. A second part of the thesis presents studies based on a subsample of these events, consisting of events with an additional jet passing specific loose tau lepton selection criteria. A data-driven method for estimating this type of background, fake factor, was studied on these events.
Concentration of salivary cortisol and testosterone in elite women football players

This study aims to evaluate the relation between salivary concentrations of cortisol (C), testosterone (T), the ratio T:C and the individual performance of top-level female soccer athletes during official matches. Eighteen female athletes from a national soccer team (age 23.06 ± 4.33 years) participated in the study. Four official matches were analysed and the on-field time of each player as well as the index of individual effectiveness were calculated. Players were classified in two clusters according to their individual performance (cluster 1 – poor individual performance; cluster 2 – good individual performance) using K-means and their hormonal variables were compared. The players of cluster 2 generally revealed higher values (p˂.05) in both the positive actions and individual effectiveness, when compared with the players of cluster 1. The players of both clusters presented identical values of C, T and T:C at the four evaluated matches. The athletes of cluster 2 showed a significant increase in C (p˂.05) and a significant decrease in T and T:C before the games lost (M2 and M5). However, there was no linear relation between the variation of both hormones during the matches and the individual performance of players. Performance in competition revealed significant differences between players, though with no apparent relation to the hormonal kinetics of C and T before and after the matches.
Orientationally ordered island growth of higher fullerenes on AgÕSi„111...-„)Ã)...R30°

The adsorption of the higher endohedral and empty fullerenes La@C 82 and C84 on Ag/Si(111)-() 3))R30° has been investigated using ultrahigh-vacuum scanning tunneling microscopy. At low coverage these molecules form single-layer islands with orientational order, a consequence of the commensurability between the intermolecular separation for each species and the surface lattice constant. The preferred adsorption site for the molecules is above an Ag trimer. Several other domains are observed at higher coverage which may be understood using a simple model. Following annealing, domains with a single orientation remain and the possibilities for epitaxial and heteroepitaxial growth are discussed.
Assessment of avifaunal assemblage and their distribution pattern across different habitat types of Gibe Sheleko National Park, South-western Ethiopia

This study was conducted in Gibe Sheleko National Park from March to August 2015 covering wet and dry seasons. Sampling sites were taken based on the habitat characteristics and a transect line of 1 or less km with a distance of 250 to 300 m in between the transect lines was taken in the woodland habitat and point count was used in the riverine forest habitat. A total of 116 bird species consisting of 2 endemics to both Ethiopia and Eritrea were recorded. The riverine habitat had higher species number (100 species, H’= 3.00) and diversity during both seasons than the woodland habitat (84 species). The number of species during the dry season (111) was higher than during the wet season (105). The variation in avifauna species number between the two habitats was not significant. However, there was a significant variation in abundance of birds between habitats (t=1.418, P<0.05 and df=1) during both seasons. The relative abundance of each species in the two habitat types was different, where the number of rare and frequent birds is somewhat higher than the other abundance ranks. Generally, avifauna species richness, diversity and relative abundance including their distribution between habitats were determined by the availability of food, vegetation structure and season. Moreover, the area is under severe pressure exacerbated by human-induced factors such as the expansion of agricultural investments, illegal settlement as well as deforestation. Therefore, significant conservation and management undertakings are very essential to maintain the biodiversity of the Park for present and future. Key words: Avifauna, Gibe Sheleko National Park, deforestation, habitat characteristics, relative abundance.
Amir Kamran Hybrid Machine Translation Approaches for Low-Resource Languages

In recent years, corpus based machine translation systems produce significant results for a number of language pairs. However, for low-resource languages like Urdu the purely statistical or purely example based methods are not performing well. On the other hand, the rule-based approaches require a huge amount of time and resources for the development of rules, which makes it difficult in most scenarios. Hybrid machine translation systems might be one of the solutions to overcome these problems, where we can combine the best of different approaches to achieve quality translation. The goal of the thesis is to explore different combinations of approaches and to evaluate their performance over the standard corpus based methods currently in use. This includes: 1. Use of syntax-based and dependency-based reordering rules with Statistical Machine Translation. 2. Automatic extraction of lexical and syntactic rules using statistical methods to facilitate the Transfer-Based Machine Translation. The novel element in the proposed work is to develop an algorithm to learn automatic reordering rules for English-to-Urdu statistical machine translation. Moreover, this approach can be extended to learn lexical and syntactic rules to build a rule-based machine translation system.
Linear filtering of systems with memory

We study the linear filtering problem for systems driven by continuous Gaussian processes V1 and V2 with memory described by two parameters. The processes Vj have the virtue that they possess stationary increments and simple semimartingale representations simultaneously. It allows for straightforward parameter estimations. After giving the semimartingale representations of Vj by innovation theory, we derive Kalman-Bucy-type filtering equations for the systems. We apply the result to the optimal portfolio problem for an investor with partial observations. We illustrate the tractability of the filtering algorithm by numerical implementations.
The Implication of IFRS Convergence on Tax/Earnings Management Behavior of Public Companies in Indonesia

The purpose of this study is to describe whether International Financial Reporting Standards (IFRS) convergence in Indonesia implies the behavior of tax management or earnings management of publicly-listed companies whose corporate income tax is not subject to final tax. This study uses a mixed approach, collecting textual data using document analysis techniques and participant observant, and collecting numerical data from public companies’ audited financial statements available on the official website of the Indonesian Stock Exchange. This study uses the Book-Tax Difference (BTD) approach to identify the behavior of tax management or earnings management. Based on 288 sample data (1,152 firm-year observations) for the 2010-2013 period, this study revealed that corporate behavior in the form of tax management or earnings management continues to occur before and after public companies adopt IFRS in their financial statement.
