Incorporating Visual Information in Audio Based Self-Supervised Speaker Recognition

The currentsuccess of deep learning largely benefits from the availability of large amount of labeled data. However, collecting a large-scale dataset with human annotation can be expensive and sometimes difficult. Self-supervised learning thus attracts many research interests to train models without labels. In this paper, we propose a self-supervised learning framework for speaker recognition. Combining clustering with deep representation learning, the proposed framework generates pseudo labels for the unlabeled dataset and learns speaker representation without human annotation. Our method starts with training a speaker representation encoder with contrastive self-supervised learning. Clustering on the learned representation generates pseudo labels, which are used as the supervisory signal for the subsequent training of the representation encoder. The clustering and representation learning process is performed iteratively to bootstrap the discriminative power of the deep neural network. We apply this self-supervised learning framework to both single modal audio data and multi-modal audio-visual data. For audio-visual data, audio and visual representation encoders are employed to learn representations of the corresponding modality. A cluster ensemble algorithm is then used to fuse the clustering results of the two modalities. The complementary information in multi-modalities ensures a robust and fault-tolerant supervisory signal for audio and visual representation learning. Experimental results show that our proposed iterative self-supervised learning framework outperforms previous works with self-supervision by large margins. Training with single modal audio data on the development set of VoxCeleb 2, our proposed framework achieves an equal error rate (EER) of 2.8% on the original test trials of VoxCeleb 1. When training with additional visual modality, the EER further reduces to 1.8%, which is only 20% higher than the fully supervised audio-based system with an EER of 1.5%. Also, experimental analysis shows that the proposed framework generates pseudolabels that are highly correlated to ground truth labels.
The relationship between sprinting speed, explosive jumping and grip strength in school children from the Western Cape.

ENGLISH ABSTRACT : To ensure success for athletes at the highest level, it is of outmost importance to develop them to the best of their abilities. There is a wide range of laboratory and field-based tests to identify talent and help develop these biomotor abilities. The long term athlete development models can help coaches to develop children to the best of their sporting abilities at the correct tempo. A total of 550 children, 275 boys and 275 girls, took part voluntarily in the study. The study design was an observational study design. The different biomotor abilities of speed, power and strength were investigated with field-based testing equipment in children. The two primary findings in the current study were the correlation between SLJ and sprinting performance in children and also the correct phase when children should train the various biomotor abilities. The boys had significantly performed better than the girls in speed (p=0.01-0.05), SLJ (p=0.01-0.05) and handgrip strength (p=0.01-0.05). The results indicated a strong correlation (r=0.61-0.85) between SLJ (measuring power) and sprinting speeds at 2.5 m, 5 m, 10 m and 20 m for boys and girls. Furthermore, the results correspond well with the YPD model that proposes that a child’s speed, power and strength can be trained and developed over an extended period throughout childhood. Initially the LTAD model were the front runner the theory that children should systematically be trained throughout childhood, but according to this model there were only specific windows of opportunities at certain ages to train certain biomotor abilities.According to results found in this study the newer athlete development models, the models after the LTAD model, is more inline and this approach should be used in future to develop children to the best of their abilities to succeed in sport at the highest level. Coaches can use reliable field-based tests like SLJ to develop talent and discover new talent%%%%AFRIKAANSE OPSOMMING : Om sukses van ŉ atleet op die hoogste vlak te verseker, is dit van kardinale belang dat die persoon tot die beste van sy vermoe ontwikkel word.

Multiscale correlated analysis of the Aguas Zarcas CM chondrite

In this paper, we report the results of a campaign of measurements on four fragments of the CM Aguas Zarcas (AZ) meteorite, combining X‐ray computed tomography analysis and Fourier‐transform infrared (FT‐IR) spectroscopy. We estimated a petrologic type for our sampled CM lithology using the two independent techniques, and obtained a type CM2.5, in agreement with previous estimations. By comparing the Si‐O 10‐µm signature of the AZ average FT‐IR spectra with other well‐studied CMs, we place AZ in the context of aqueous alteration of CM parent bodies. Morphological characterization reveals that AZ has heterogeneous distribution of pores and a global porosity of 4.5 ± 0.5 vol%. We show that chondrules have a porosity of 6.3 ± 1 vol%. This larger porosity could be inherited due to various processes such as temperature variation during the chondrule formation and shocks or dissolution during aqueous alteration. Finally, we observed a correlation between 3D distributions of organic matter and mineral at micrometric scales, revealing a link between the abundance of organic matter and the presence of hydrated minerals. This supports the idea that aqueous alteration in AZ’s parent body played a major role in the evolution of the organic matter.
An integrated methodology for the used product selection problem faced by third-party reverse logistics providers

Abstract The rise of electronic commerce and the stricter government regulations on the recovery of end-of-life products increased the number of products returned by customers. A company may deal with increasing product returns by developing its own reverse logistic system. However, high fixed costs associated with dedicated reverse logistics equipment and infrastructure force many companies to outsource their reverse logistics operations to third-party reverse logistics providers. One of the important problems faced by third-party reverse logistics providers is the selection of the types of used products to be collected. In this study, a four-phase used product selection methodology is proposed. First, the quantitative and qualitative selection criteria are determined. Then the weights of the criteria are calculated using fuzzy analytic hierarchy process. Next, simulation models are employed to determine the values of quantitative criteria. Finally, technique for order preference by similarity to ideal solution ranks alternative used product types. A numerical example is also provided in order to present the applicability of the proposed methodology.
Simulation and Design of InAs Nanowire Transistors Using Ballistic Transport

The purpose of this thesis is to describe the modeling of the performance of InAs nanowire MOSFETs and to study their performance as parameter of the transistor’s structure (e.g., diameter, gate dielectric thickness, and gate dielectric constant) were changed. This study was performed using the FETToy (www.nanohub.org) modeling software [35, 36] developed at Purdue University. FETToy is composed of several Matlab scripts and is used to simulate ballistic transport in the calculation of the current-voltage (I-V) characteristics for nanoscale double gate silicon MOSFETs. By modifying the semiconductor’s effective mass, the program can be used to model semiconductors other than silicon. This thesis presents in Chapter 2 the initial modeling results for an InAs nanowire MOSFET in comparison with the published experimental results for a 80 nm diameter nanowire MOSFET as reported by Bryllert et al.’s (Sweden) group [23, 24]. Comparisons were made of the simulation results to the experimental results for the transistor’s drain current versus gate voltage to extract the threshold voltage, the transistor’s output characteristics (drain current versus drain bias for various gate voltages), the log of the drain current versus the gate voltage (subthreshold plot), and the transconductance versus gate voltage for a drain voltage in the saturation region. Chapter 3 describes the results obtained from varying the transistor’s structure from the initial one used in Chapter 2 to compare with the published experimental results. This includes the effects on transistor performance of variation in the nanowire diameter, gate dielectric thickness, and gate dielectric constant. This chapter also pursues the optimization of the device’s performance by altering the device’s structure. We conclude this thesis by summarizing the work presented here and offering suggestions for future work.
Pengguna Media Interaktif Sebagai Kenyataan Maya: Studi Resepsi Khalayak Suarasurabaya.net Sebagai Media Interaktif

My aim in writing this paper is to describe that in this fast-changing world, media in Indonesia has undergone a rapid transformation. Digital technology continues to reshape the mass media landscape using internet technology. Internet brings a technical communication revolution, a fundamental change takes place in the structure of connections, artificial memories and the reproduction of their content. Internet technology has made communication much easier and less expensive. It has attracted many people and has penetrated into people’s daily lives. The mass media also have accepted the internet. Almost all forms of traditional media (old media) in local media, such as radio, television, and newspaper have extended their work into this new field. The internet and the World Wide Web have both significantly influenced modern journalism. In online media allows readers to enjoy browsing their product and service of contents, such as news feed, podcasts, desktop alert, news on mobile phones, PDA and others mobile devices. Online media offer not only text but also digital images , audio file, moving images (video), internet radio and internet t v. The interactive features of the internet seemingly imply that online media have more advantages than traditional media forms (old media). So, the internet have dramatically evolved become new media with characteristic multimedia, hypertext, interactivity, archives , and virtuality. The most important structural new media characteristic is the integration of telecommunications, data communications and mass communication in a single medium – it is the convergence. It should be pointed out that the trend toward digital is affecting the various media and brings the local media in East Java to become a global media, where breaking news from Surabaya or anywhere in East Java is transmitted to around the world in a matter of minutes . The research was carried out to find out how user reception on convergence media, journalism and local media on the site of SuaraSurabaya.net and how to access subjective meanings that they have created based on t heir understanding on online media so far. The research is also interested in looking into user reception on information and communication technology based on its relevance with the selected theme namely discourses on global media in website of Radio Suara Surabaya.
SIMULATION AND DESIGN OF GERMANIUM-BASED MOSFETs FOR CHANNEL LENGTHS OF 100 nm AND BELOW

Conventional silicon MOSFETs are rapidly approaching the end of the roadmap for conventional scaling techniques. As a result, alternative device designs, such as transport-enhanced FETs along with other semiconductor technologies, such as multigate transistors, are being investigated. Transport-enhanced FETs simply employ new materials in the channel region of MOSFETs with higher carrier mobilities and velocities than silicon. Since the electron and hole mobilities in germanium are considerably larger than those of silicon, Ge-based MOSFETs are being considered as a replacement for conventional Si MOSFETs for both pand n-channel transistors for CMOS applications. Long-channel Ge MOSFETs have already been demonstrated exhibiting considerable performance enhancements over comparable Si devices. The Ge devices in these studies showed improvements over the Si devices in the output drain current, effective mobility, and small signal transconductance. The purpose of this study is to examine the performance capabilities and scaling behavior of short channel Ge-based n-MOSFETs using a commercial numerical device simulator from ISE Corporation. This thesis will describe the results of DC and small signal AC simulations of the device’s transistor characteristics and compare them with those for a silicon device of the same geometry and size. We will also examine the effects of variations in the device structure on the Ge MOSFET’s performance, including the transconductance and high frequency response.

Studying Statewide Political Campaigns

TH E R E I S L I T T L E I N T H E AC A D E M I C literature about the dynamics of campaign advertising strategies and their effects on candidate electoral success. While there have been theoretical and empirical studies of campaign strategy (Ferejohn and Noll 1978; Skarpedas and Grofman 1995; Glazer 1990) and scattered treatments of candidate advertising strategies (Roddy and Garramone 1988; Merritt 1984), our lack of understanding of the dynamics of advertising strategies has led some to wonder how much “campaigns matter” (Finkel 1993). The difAculty in examining campaign dynamics stems from the lack of consistent data on candidate advertisements (West 1993). What little is known about campaign advertisements comes from selective sampling of television advertisements from presidential campaigns (West 1993) or from experimental studies (Ansolabehere et al. 1994; Ansolabehere and Iyengar 1995; Garramone 1985; Garramone et al. 1990). Presidential campaigns, however, have several characteristics that make them ill-suited for studying the effects of advertising strategies. As Lau and Pomper note, presidential campaigns feature the most prominent political Agures, who are less likely to be “redeAned” by an opponent’s attack advertisement. Further, presidential candidates enjoy much more media exposure than do Senate or gubernatorial candidates (Lau and Pomper 2002). Most important, there is little variation in advertising strategies and the intensity of advertising across presidential campaigns. Finally, there is a very limited sample of presidential elections. In this essay, we concentrate our analysis on two statewide races held in California. There recently has been some interest in studying statewide

A Review of the Factors Influencing the Performance of University-Enterprise Cooperation Innovation

In the rapid development of today, enterprises only rely on their own ability has been difficult to adapt to market demand; many enterprises choose to cooperate with the university to innovate, in order to improve their innovation ability and competitiveness. Also the university will invert the scientific research into market, and achieve the purpose of win-win cooperation. In this paper, university-enterprise cooperation as the background, to explore the impact of university-enterprise cooperation innovation performance of various factors, and classified review, was mainly divided into three aspects, like cooperation network structure perspective, spatial geography perspective and social factors perspective.
Relationships between patterns of incubation and predation in sympatric capercaillie Tetrao urogallus and black grouse T. tetrix

To investigate the effect of timing, frequency and duration of incubation recesses of female grouse on predation, thermistors were placed in 29 nests of capercaillie Tetrao urogallus and 10 nests of black grouse Tetrao tetrix in southeast Norway during 1983-84. Two female capercaillie were killed by goshawks Accipiter gentilis during recesses and 15 capercaillie and three black grouse nests were depredated. The incubation patterns of 20 caper­ caillie and nine black grouse were measured during 165 and 75 days, respectively. There was no difference between species in how long females stayed away from the nest each day, but black grouse took more and short­ er recesses than capercaillie. The recess activity of both species peaked before and after a period of low activity during the night. Although black grouse took the first recess earlier and the last recess later than capercaillie, they also took few recesses in dim light. Nest losses were not associated with the time or frequency of departures from the nest. The data presented suggest that factors other than predation risk may be responsible for the pat­ terns of incubation recesses observed in grouse.
Causal Models and the Logic of Counterfactuals

Causal models provide a framework for making counterfactual predictions, making them useful for evaluating the truth conditions of coun-terfactual sentences. However, current causal models for counterfactual semantics face limitations compared to the alternative similarity-based approach: they only apply to a limited subset of counterfactuals and the connection to counterfactual logic is not straightforward. This paper argues that these limitations arise from the theory of interventions where intervening on variables requires changing structural equations rather than the values of variables. Using an alternative theory of exogenous interventions, this paper extends the causal approach to counterfactuals to handle more complex counterfactuals, including backtracking counterfactuals and those with logically complex antecedents. The theory also validates familiar principles of counterfactual logic and oﬀers an explanation for counterfactual disagreement and backtracking readings of forward coun-terfactuals.
