The Signals Of Dividend

Dividend decisions is a type of policy that earnings should be distributed to shareholders and sometimes contrast with the interest by insiders whether to retain or reinvest. The objective of this study is to examine the determinants of dividend policy on 230 listed firms in period of 2010 to 2011 and conducts logistic regression for hypothesis testing. This study finds that profitability, firm size, and institutional ownership are significant to dividend policy while managerial ownership is insignificant. This findings indicate that most of listed firms of the sample of this study determine the dividend policy based on profits. This study also finds that more larger the firms or institutional ownership then they tend to increase the dividends. Limited to sample, this study proves that agency theory is not applicable for dividend policy in Indonesia as the managerial ownership have no relationship with the dividend policy

Visualising urban sustainability

Developing sustainable urban environments is complex and requires a number of factors – including social, economic and environmental sustainability - to be taken into account. This project is prototype software that produces a 3D virtual model of urban developments allowing viewers to see the short and long-term implications of courses of action

Signals with an Additive Fractal Structure for Information Transmission

This chapter is devoted to a new class of wideband signals with an additive fractal structure. Properties and characteristics of the new type of signals are studied. It is shown that such signals possess a high level of an irregularity and unpredictability at simple technical implementation. It is shown that an incommensurability of frequencies of fundamental high-stable oscillations leads to the high level of an irregularity of such signals. For an estimation of a level of signal complexity, authors offer to use the fractal dimensionality of their temporal implementations calculated by means of creation of the structural function. Methods of modification of the signal spectrum with the additive fractal structure are offered, permitting to increase the efficiency of the frequency resource application. For reduction of the high low-frequency signal power the authors suggest using signals with the additive fractal structure, centered in a moving average window. Methods of masking of the voice messages by means of signals of a new type are offered. The results of a computer experiment of secretive sound transmission are described

Does Maturity Signals High Risk and High Return?

The objective of this study is to examine the interaction between firm maturity and firm growth opportunities over risk and its impact on returns. This study uses 135 firms listed in Indonesia Stock Exchange during 2010 to 2016 as sample which gives 945 as total observed data. This study conducts path analysis in term for hypothesis testing and finds that firm maturity has significant role to increase the risk which gives impact on increasing the returns. In context of Indonesian firms, the findings imply that mature firms will have higher risk and higher returns

Advancing Artificial Intelligence in Sensors, Signals, and Imaging Informatics.

ObjectiveTo identify research works that exemplify recent developments in the field of sensors, signals, and imaging informatics.MethodA broad literature search was conducted using PubMed and Web of Science, supplemented with individual papers that were nominated by section editors. A predefined query made from a combination of Medical Subject Heading (MeSH) terms and keywords were used to search both sources. Section editors then filtered the entire set of retrieved papers with each paper having been reviewed by two section editors. Papers were assessed on a three-point Likert scale by two section editors, rated from 0 (do not include) to 2 (should be included). Only papers with a combined score of 2 or above were considered.ResultsA search for papers was executed at the start of January 2019, resulting in a combined set of 1,459 records published in 2018 in 119 unique journals. Section editors jointly filtered the list of candidates down to 14 nominations. The 14 candidate best papers were then ranked by a group of eight external reviewers. Four papers, representing different international groups and journals, were selected as the best papers by consensus of the International Medical Informatics Association (IMIA) Yearbook editorial board.ConclusionsThe fields of sensors, signals, and imaging informatics have rapidly evolved with the application of novel artificial intelligence/machine learning techniques. Studies have been able to discover hidden patterns and integrate different types of data towards improving diagnostic accuracy and patient outcomes. However, the quality of papers varied widely without clear reporting standards for these types of models. Nevertheless, a number of papers have demonstrated useful techniques to improve the generalizability, interpretability, and reproducibility of increasingly sophisticated models

Singular ARMA signals

Singular random signals are characterized by the fact that their values at each time are singular random variables, which means that their distribution functions are continuous but with a derivative almost everywhere equal to zero. Such random variables are usually considered as without interest in engineering or signal processing problems. The purpose of this paper is to show that very simple signals can be singular. This is especially the case for autoregressive moving average (ARMA) signals defined by white noise taking only discrete values and filters with poles located in a circle of singularity introduced in this paper. After giving the origin of singularity and analyzing its relationships with fractal properties, various simulations highlighting this structure will be presented

Multiplexing Biochemical Signals

In this paper we show that living cells can multiplex biochemical signals, i.e. transmit multiple signals through the same signaling pathway simultaneously, and yet respond to them very specifically. We demonstrate how two binary input signals can be encoded in the concentration of a common signaling protein, which is then decoded such that each of the two output signals provides reliable information about one corresponding input. Under biologically relevant conditions the network can reach the maximum amount of information that can be transmitted, which is 2 bits.Comment: 4 pages, 4 figure

Stealth multiboson signals

We introduce the `stealth bosons' $S$, light boosted particles with a decay $S \to AA \to q \bar q q \bar q$ into two daughter bosons $A$, which subsequently decay into four quarks that are reconstructed as a single fat jet. Variables that measure the two-pronged structure of fat jets, which are used for diboson resonance searches in hadronic or semi-leptonic final states, classify the jets produced in stealth boson decays as QCD-like - actually, for these variables they may seem more background-like than the QCD background itself. The number of tracks in those jets can also be, on average, much higher than for the fat jets arising from the hadronic decay of boosted $W$ and $Z$ bosons. Therefore, these elusive particles are hard to spot in standard searches. Heavy resonances decaying into two such stealth bosons, or one plus a $W/Z$ boson, could offer an explanation for the recurrent small excesses found in hadronic diboson resonance searches near an invariant mass of 2 TeV.Comment: LaTeX 32 pages. v2: three appendices added as well as many additional discussions, journal versio

Glasgow time signals

From 1859 to 1864, both visual and audio one o’clock time signals operated in Glasgow. Although the University carried a remit to provide the city’s time, following convoluted processes of establishment, a local chronometer-maker operated a time ball for 4 years. Towards the end of the period, time guns were triggered by telegraph from the Royal Observatory Edinburgh. Both exercises caused aggravation for the University. For the ball, the Professor of Astronomy, John Pringle Nichol, failed to convince the City Council that the “drop” control should originate from the University’s Observatory. For the guns, Robert Grant, the newly appointed Astronomy Chair holder, was aggrieved by the Astronomer Royal for Scotland, Piazzi Smyth, appearing to operate above his station. Rather than having only a once per day reference, both projects were abandoned as the University laid a dedicated telegraph cable from its observatory to control many public clocks and additional clocks with large sweep fingers indicating exact time to the second

Profile of multiboson signals

We investigate the visibility of signals characterised by wide bumps over a smoothly falling background that cannot be accurately predicted by Monte Carlo calculations. Examples of such are the wide bumps that triboson and quadriboson resonance cascade decays would yield in diboson resonance searches in fully hadronic final states. We find that the sensitivity to triboson bumps is rather small: signals of a moderate size could be present in current data and yet remain unnoticed. For quadriboson cascade decays the signals can hardly be distinguished from the background in the current searches.Comment: LaTeX 17 pages. v2: fixed typos and comments added; journal versio
