CHANNEL ESTIMATION FOR MASSIVE MIMO USING SPARSE BAYESIAN LEARNING METHOD

Pilot contamination creates a fundamental limit to the potential benefits on the performance of massive multipleinput multiple-output (MIMO) systems. Due to failure in accurate channel estimation the author proposed spares Bayesian learning (SBL) method on Gaussian framework. To address this problem, we propose to estimate channel coefficient by its own hyper parameter and also to its adjacent cells. The required estimation is, nonetheless, an underdetermined system. In this paper the simulation results show that the channel coefficients can be estimated more efficiently in contrast to the conventional channel estimators in terms of channel estimation with pilot contamination. A pilot design criterion is proposed to design the optimal pilot to improve the estimation accuracy of the proposed algorithm using the Lagrange multiplier optimization method. Results show that we can reduce the MSE of the SBL estimator by employing the optimal pilot sequence. As a result, if the signals are observed in the beam domain (using Fourier transform), the channel is approximately sparse, i.e., the channel matrix contains only a small fraction of large components, and other components are close to zero.

Funding Source and Disclosure Practices of Religious Nonprofit Organizations : A Test of Interdependence Theory

This study tested an interdependence theory in funding source and disclosure practices of the religious nonprofit organizations (RNPOs). From a sample of 83 RNPOs, results indicated that government-funded RNPOs were more likely to disclose information. These results provide vindication of interdependence theory and suggest that board of trustees engagement with the government contribute to the organizational resources. Key-Words: disclosure, funding, interdependence theory, religious nonprofit organizations
Solid-substrate Fermentation of Wheat Grains by Mycelia of Indigenous Ganoderma spp . Enhanced Adipogenesis and Modulated PPAR γ Expression in 3 T 3L 1 Cells

Adipocyte dysfunction is strongly associated with the progression of cardiovascular risk factors and diabetes. Appropriate regulation of adipogenesis and adipokine expression, notably adiponectin, are known to prevent or delay the onset of these disorders. The present study evaluated the insulin-like properties of ethanol extract of indigenous Ganoderma australe (KUM60813) and Ganoderma neo japonicum (KUM61076) through adipogenic, anti-lipolytic and adipogenesis targeted gene expression in differentiated 3T3-L1 adipocytes. Ganoderma lucidum (VITA GL) (a commercial strain) was included in the study as a reference. 3T3-L1 adipocytes treated with ethanol extract of wheat grains fermented with G. neo japonicum mycelia, significantly stimulated adipogenesis and exerted relatively mild anti-epinephrine induced lipolytic activities. In general, the expressions of target genes such as adiponectin, peroxisome proliferatoractivated receptor gamma (PPARγ), glucose transporter 4 (GLUT4) and hormone sensitive lipase (HSL) were up-regulated by the ethanol extract of wheat grains fermented with Ganoderma spp. mycelia. Taken together, these results suggest that Ganoderma especially G. neo-japonicum has insulin-like properties and may be useful as potential therapeutic agent in the management of type 2 diabetes mellitus.
Selection for Seed Yield in Cross Population Giza 429 x Giza 40 of Faba Bean

The present investigation was carried out during 2013/2014, 2014/2015 and 2015/2016 successive seasons, at Experimental Farm Faculty of Agriculture (Assiut Branch) Al-Azhar University. The obtained results showed that the expected response to selection was lower than the actual response to selection for the studied traits in respect to the two selection criteria number of pods/plant and seed yield/plant. The results showed that the average plants recorded lower values in F3 generation and increased gradually in the next generation for the studied traits except, average for days to maturity which recorded higher values in F3 generation and decreased gradually in the next generation for the two selection criteria. In plant height (cm), number of pods/plant, seed index (100-seed weight gm.) and seed yield/plant (gm) the average of the bulk populations was less than those for selected families in F3, F4 and F5 generations, except, for number of days to maturity where in the bulk populations was higher than selected families in F3, F4 and F5 generations for the two selection criteria. Phenotypic and genotypic coefficients of variability recorded higher values in F3 generation and decreased gradually in the next generation for the studied traits. Positive and significant phenotypic and genotypic correlation coefficients were recorded between seed yield per plant and all the studied traits, except days to maturity it was negative and significant for the two selection criteria. Heritability in narrow sense was high (>50%) for plant height and 100-seed weight in F4 and F5 and varied from low to moderate for the remaining traits.
Designing Customizable Network-on-Chip with support for Embedded Private Memory for Multi-Processor System-on-Chips

The computer industry’s transition to multiprocessor systems on chip (MPSoC) architectures is increasing the need for new scalable high-bandwidth on-chip communication backbones. Networkon-Chip (NoC) interconnects are gaining interest for serving as the on-chip communication infrastructure. The most important issues to be considered in designing a NoC are topology, routing algorithm, flow control, and buffering and also the trade-offs between performance, power, and area. This research proposes a custom-designed NoC specifically for MPSoCs on FPGAs. The proposed design allows the communication infrastructure to seamlessly scale as the numbers of processors within the chip increases. The design adds a new level of abstraction to remote-access transactions. The design also considers support for the partitioned global address space model with support for optional embedded local memories embedded in the network interface. The network was designed as a mesh topology to allow a reasonable communication capacity in 2-Dimensional space. The communication protocol between source and destination is AMBA AXI4, and the communication between each two adjacent nodes, is typical AXI type valid/ready handshake. The nodes are distinguished by their user specified address range. Each node is assigned a range of addresses, and in each transaction, based on the destination address, the routers decide the the next node, until the transaction reaches the destination. The design has been implemented on a Xilinx Virtex7 FPGA. However, there is no platform dependency to any brand or any model of FPGAs.

Deception in Computer-Mediated Communication

Why do people lie? The reasons are as varied as human life itself, but there is almost always a reason, and these reasons can be categorized in a variety of ways. St. Augustine, for example, classified lies into eight types of varying severity. Modern psychology has produced smaller taxonomies. In the influential self-presentational framework of deception (DePaulo, Lindsay, et al. 2003; Vrij 2008a), people lie to enhance or protect their own self-image (self-oriented), their partner’s (partneroriented), or some third party (altruistic). According to this view, most everyday conversational lies are part of an effort to manage interactions with others and achieve self-presentational goals (Goffman 1959). Other lies, like those associated with scandals or crime, may be less about self-presentation goals and more about seeking material rewards or avoiding prosecution, but lies are still a means to accomplishing something in the world. Since lies are useful for accomplishing goals in the world, why not simply lie all the time? A whole host of factors constrain the use of deception. Some of these constraints are external, such as the social stigma associated with being caught lying. Because humans are social animals, it is important to have the trust of other humans. Getting caught lying can damage that trust (Möllering 2006) and even ultimately destroy the ability to communicate with one another (Grice 1989). Other constraints against lying are internal. Most people view themselves as honest, and this self-concept of an honest person can shackle how much one is prepared to lie. In a series of experiments, Ariely and colleagues (Mazar and Ariely 2006) demonstrated that even when there was no possibility of being caught, participants in their experiments only lied by a fraction of the full amount they could have lied, suggesting that the self-concept of honesty prevents people from lying too much. In this view, the act of lying is a sort of calculus. Lying can be a tool for accomplishing things in the world, but it is restricted by internal and external constraints. The question addressed here is whether communication technologies, like telephones, email, and text messaging, enter into this calculus. And, once the decision to lie has been made, what are the implications for language? The present chapter has two primary interests. The first is a concern with how communication and information technology affect the pragmatic calculus of deception, and what features of these new communication spaces may enter into this calculus. The focus is on everyday social interactions, which in the present era are
CLEAR SKY ANGULAR DEPENDENCE MODELS OVER OCEANS FROM CERES

Measurements from the Earth Radiation Budget Experiment (ERBE) and the recent Clouds and the Earth's Radiant Energy System (CERES) have been successfully used in monitoring the outgoing energy from the earth-atmosphere system for more than three decades. These measurements include the broad band shortwave (SW) and longwave (LW) radiances at the top of the atmosphere, and angular distribution models (ADMs) are used to invert measured radiances to fluxes. Current ADMs, however, do not account for aerosols and surface effects such as wind speed. In this study, aerosol angular distribution models are constructed for biomass burning and dust regions for September 2000 over cloud free oceans, using the cross track and rotational azimuth plane scan mode CERES data. The Moderate-Resolution Imaging Spectroradiometer (MODIS) is collocated with CERES data, and used to discriminate aerosol scenes from totally clear and cloudy scenes within the CERES pixels. As indicated in this study, lack of dust aerosol ADMs could induce an increase in the derived SW aerosol direct forcing (SWARF) on the order of 20%. This study shows that at certain observation geometries, if ocean surface wind speeds are not considered when building ADMs, it could lead to maximum errors in shortwave fluxes on the order of 30-60%.
STABILITY CROSSING CURVES OF SISO SYSTEMS CONTROLLED BY DELAYED OUTPUT FEEDBACK

This paper focuses on closed-loop stability analysis of a class of linear single-input singleoutput (SISO) systems subject to delayed output feedback. The considered approach makes use of some geometric arguments in frequency-domain, arguments that simplify the understanding of the delay stabilizing mechanism. More precisely, the geometry of stability crossing curves of the closed-loop system is explicitly characterized (classification, tangent and smoothness, direction of crossing) in the parameter space defined by the pair (gain, delay). Such stability crossing curves divide the corresponding parameter space into different regions, such that, within each region, the number of characteristic roots in the righthalf plane is fixed. This naturally describes the regions of (gain, delay)-parameters where the system is stable. Various illustrative examples complete the presentation.
Loughborough University Institutional Repository Professional fulfillment : Concept and instrument proposition

This paper aims to propose a concept and an instrument of professional fulfillment (PF), which is theoretically defined as the perception of having attained or being on the right track for attaining one’s most important career goals. The Professional Fulfillment Scale (PFS) was developed in order to operationalize PF, being tested across two studies. Regarding Study 1, in which 406 workers took part, results from exploratory factor analysis evidenced construct validity for PFS. In Study 2, in which 270 workers took part, results from confirmatory factor analysis and structural equation modeling presented satisfactory model fit indices for PFS. We conclude that both the professional fulfillment concept and the scale are useful for mapping people’s importance and achievement of career goals and evaluation of progress, working as a diagnostic tool for career management.
Generational Driven Search Behavior on Google

The expanded internet usage has resulted in an increased activity at web-based search engines. Companies are therefore devoting a large portion of their online marketing budget on Search Engine Marketing (abbreviated SEM) in order to reach potential online consumers searching for products. SEM comprises Search Engine Advertising (SEA) and Search Engine Optimization (SEO) which are two dissimilar marketing tools companies can invest in to reach the desired customer segments. It is therefore of great interest for companies in different product markets to have knowledge of which SEM strategy to utilize. The statement leads to the purpose of the thesis which is to investigate which SEM strategy is the most suitable for companies in different markets, SEA or SEO? The purpose of the thesis is derived to the research problem: How does the search behavior of consumers differ between the two SEM tools, SEO and SEA? Initially, in order to answer the research problem, a theoretical framework was conducted consisting of theories from previous research. To collect primary data observations of 60 test subjects was performed in accordance with the Experimental Vignette Methodology. The analysis consists of a comparison between the collected data and the theories included in the frame of reference, to identify similarities and differences. The SPSS analysis of the result revealed numerous findings such as the two-way interactions of the factors degree of involvement and the click rate of SEM, as well as the choice of either a head or a tail keyword and the degree of involvement. The analysis further revealed a three-way interaction which suggests that the degree of involvement, and the use of either a head or tail keyword affects the choice of SEM. Additionally, the result shows that customers using brands as keywords are more likely to click on an organic link rather than on a paid ad. However, when adding the factor age to the analysis the results turn insignificant. As the area of search behavior of customers using search engines is relatively scientifically unexplored, the thesis has contributed with knowledge useful for companies, marketing agencies, among others. However, due to the ongoing expansion of search engine usage, it is of great interest to conduct further research in the area to reveal additional findings.
Generic Authenticated Data Structures, Formally

8 Authenticated data structures are a technique for outsourcing data storage and maintenance to an 9 untrusted server. The server is required to produce an eﬃciently checkable and cryptographically 10 secure proof that it carried out precisely the requested computation. Recently, Miller et al. [10] 11 demonstrated how to support a wide range of such data structures by integrating an authentication 12 construct as a ﬁrst class citizen in a functional programming language. In this paper, we put this 13 work to the test of formalization in the Isabelle proof assistant. With Isabelle’s help, we uncover 14 and repair several mistakes and modify the small-step semantics to perform call-by-value evaluation 15 rather than requiring terms to be in administrative normal form. 16
Design and Simulation of Vehicular Adhoc Network using SUMO and NS 2 1

Imagine a situation in which a vehicle shares its beacon information such as position, speed, direction, etc. in addition safety message such as traffic, slippery, road condition etc with other nearby vehicles so that nearby vehicle can know the status of traffic, accident information, road conditions etc. before reaching or facing it. Thereby, we can reduce road accidents, decrease the waiting at traffic signals, save the life of people. We are initiated to design and analysis of the transmitter of a vehicle node which communicates the in high dynamic environment and frequent connectivity change situation. We analyzed the average packet success ratio and throughput of VANET in Real Traffic environments for various routing protocols. Our proposed design and analysis proved that transmitter is suitable for vehicle to vehicle communication and performs better result in real traffic conditions and high dynamic environment.
Bones, Oliver and Hopkins, Kathryn and Krishnan, Ananthanarayan and Plack, Christopher J (2014)Phase locked neural activity in the human brain- stem predicts preference for musical consonance

When musical notes are combined to make a chord, the closeness of fit of the combined spectrum to a single harmonic series (the ‘harmonicity’ of the chord) predicts the perceived consonance (how pleasant and stable the chord sounds; McDermott, Lehr, & Oxenham, 2010). The distinction between consonance and dissonance is central to Western musical form. Harmonicity is represented in the temporal firing patterns of populations of brainstem neurons. The current study investigates the role of brainstem temporal coding of harmonicity in the perception of consonance. Individual preference for consonant over dissonant chords was measured using a rating scale for pairs of simultaneous notes. In order to investigate the effects of cochlear interactions, notes were presented in two ways: both notes to both ears or each note to different ears. The electrophysiological frequency following response (FFR), reflecting sustained neural activity in the brainstem synchronised to the stimulus, was also measured. When both notes were presented to both ears the perceptual distinction between consonant and dissonant chords was stronger than when the notes were presented to different ears. In the condition in which both notes were presented to the both ears additional low-frequency components, corresponding to difference tones resulting from nonlinear cochlear processing, were observable in the FFR effectively enhancing the neural harmonicity of consonant chords but not dissonant chords. Suppressing the cochlear envelope component of the FFR also suppressed the additional frequency components. This suggests that, in the case of consonant chords, difference tones generated by interactions between notes in the cochlea enhance the perception of consonance. Furthermore, individuals with a greater distinction between consonant and dissonant chords in the FFR to individual harmonics had a stronger preference for consonant over dissonant chords. Overall, the results provide compelling evidence for the role of neural temporal coding in the perception of consonance, and suggest that the representation of harmonicity in phase locked neural firing drives the perception of consonance. & 2014 The Authors.

Second language writing online: An update

I last wrote an overview of developments in second language (L2) online writing 10 years ago (GodwinJones, 2008). Since that time, there have been significant developments in this area. There has been renewed interest in L2 writing through the wide use of social media, along with the rising popularity of computer-mediated communication (CMC) and telecollaboration (class-based online exchanges). The recognition of writing as a social act has also led to a significant rise in interest in collaborative writing. This has been aided by the popularity of tools providing a shared writing space, such as Google Docs. The importance and recognition of genre in both student work and writing theory have grown considerably among practitioners and researchers. The increased practice of integrating multimedia into writing is reflected in the popularity of multimodal projects, such as digital storytelling. At the same time, digital tools for evaluating writing have become more widely available in the form of digital annotators and automated writing evaluation (AWE) software, which take advantage of advances in corpus linguistics and natural language processing (NLP). In addition, tools for processing and evaluating large data sets enable approaches from data mining that provide valuable insights into writing processes. The variety and, in some cases, the complexity of online writing environments has increased the need for both learner and teacher training.
