TRIPLY NONCENTRAL BIVARIATE BETA TYPE V DISTRIBUTION

The enriched triply noncentral bivariate beta type V distribution is introduced. This distribution is constructed from independent chi-squared random variables by using the variables-in-common (or trivariate reduction)technique. The marginal density, product moment and the distribution of the product of the correlated components of this distribution are also derived. The effect of the additional parameters on the shape of the density functions and the correlation between the correlated variables is shown. Special cases are highlighted to position this distribution in the bivariate beta distributions context.

Rethinking professional learning in higher education: a study on how the use of Open Educational Resources triggers the adoption of Open Educational Practice

This study explores how the practices of higher education educators evolve towards open educational practice (OEP) as they use open educational resources (OER) as a form of social media. Drawing on the theories of self-regulated learning (SRL) and cultural-historical activity theory (CHAT), the study provides a novel way of analysing learning and development at work by focusing on related tensions. The interview data were, firstly, analysed by a thematic categorisation of 6 sub-categories of self-regulated learning and secondly, by using the method of discursive manifestations of contradictions. The findings evidence that educators find that their OEP does not fit easily within the current educational system. They have to balance conventional forms of education at scale with new and emerging open forms of education. This creates tensions indicating that educators need support in evolving their educational practice towards OEP and to reflect on what this change means for their practice.
EFFECT OF PROCESS PARAMETER VARIATION ON ft IN CONVENTIONAL AND JUNCTIONLESS GATE-ALL-AROUND DEVICES

In this paper we have studied the effect of process variations on unity gain cutoff frequency (ft) in conventional and junctionless gate-all-around (GAA) transistors using TCAD simulations. Three different geometrical parameters, channel doping, source/drain doping (for conventional GAA), wire doping (for junctionless GAA) and gate electrode work function are studied for their sensitivity on ft. For conventional GAA, ft is more sensitive to gate length and source/drain doping and less sensitive to gate oxide thickness, ovality and channel doping and least sensitive to gate work function variations. For junctionless GAA, ft is more sensitive to gate length and gate work function variations and less sensitive to gate oxide thickness, ovality, wire doping. The non-quasi static (NQS) delay is extracted for the most sensitive parameters. The trend of NQS delay is just the reverse trend of ft.

Role of environmental pollution in prevalence of antibiotic resistant bacteria in aquatic environment of river: case of Musi river, South India

Antibiotic resistance in clinical settings has been studied from last few decades but the possibility of development of antibiotic resistance at polluted environmental sites is also of concern. In developing countries, the major source of antibiotic contamination in surface water is improper disposal of effluents from industries, hospitals and domestic waste water treatment plants. The antibiotic pollution combined with other environmental pollution factors exerts selective pressure on environmental microbes, driving evolution and resulting in the spread of antibiotic resistance in a local to global scale. Present study aimed to determine the proliferation of ciprofloxacin resistant bacteria in aquatic environment of a river which is heavily impacted by industrial effluents. Correlation analyses were performed to evaluate the impact of anthropogenic factors. Statistical analysis evaluated the effect of fluoroquinolones, heavy metals, total organic carbon and total nitrogen on the levels of resistant culture in samples from the natural settings.
Linear Modification

[Elements as they are added one by one to form a sentence progressively limit the semantic range of all that has preceded. This causes beginning elements to have a wider semantic range than elements toward the end. The concept of linear modification thus developed knits together a number of otherwise heterogeneous manifestations of sentence order in English, and provides a plausible theory of adjective position. ] The linear geometry of the sentence imposes certain relationships upon the elements that compose it. These relationships are conveniently expressed as dichotomies. Two dichotomies are, figuratively, spatial: they are contiguous versus separate (A is next to B or is distant from B) and within versus without (A is contained within B or is outside B). Two dichotomies are temporal : first versus last and before versus after. While it does not follow that any of these pairs necessarily has linguistic importance, given their location at the very foundation of sentence structure it would be strange if they had not been seized upon for some use in communication. I think it can be shown that all of them have, probably in all languages, though I am concerned here only with the last two, the temporal dichotomies, and even with these, only in two languages.
Image Segmentation Approaches for Weld Pool Monitoring during Robotic Arc Welding

There is a strong correlation between the geometry of the weld pool surface and the degree of penetration in arc welding. To measure the geometry of the weld pool surface robustly, many structured light laser line based monitoring systems have been proposed in recent years. The geometry of the specular weld pool could be computed from the reflected laser lines based on different principles. The prerequisite of accurate computation of the weld pool surface is to segment the reflected laser lines robustly and efficiently. To find the most effective segmentation solutions for the images captured with different welding parameters, different image processing algorithms are combined to form eight approaches and these approaches are compared both qualitatively and quantitatively in this paper. In particular, the gradient detection filter, the difference method and the GLCM (grey level co-occurrence matrix) are used to remove the uneven background. The spline fitting enhancement method is used to remove the fuzziness. The slope difference distribution-based threshold selection method is used to segment the laser lines from the background. Both qualitative and quantitative experiments are conducted to evaluate the accuracy and the efficiency of the proposed approaches extensively.
Design of a Huggable Social Robot with Affective Expressions Using Projected Images

We introduce Pepita, a caricatured huggable robot capable of sensing and conveying affective expressions by means of tangible gesture recognition and projected avatars. This study covers the design criteria, implementation and performance evaluation of the different characteristics of the form and function of this robot. The evaluation involves: (1) the exploratory study of the different features of the device, (2) design and performance evaluation of sensors for affective interaction employing touch, and (3) design and implementation of affective feedback using projected avatars. Results showed that the hug detection worked well for the intended application and the affective expressions made with projected avatars were appropriated for this robot. The questionnaires analyzing users’ perception provide us with insights to guide the future designs of similar interfaces.
Securing IEEE P1687 On-chip Instrumentation Access Using PUF

As the complexity of VLSI designs grows, the amount of embedded instrumentation in system-on-a-chip designs increases at an exponential rate. Such structures serve various purposes throughout the life-cycle of VLSI circuits, e.g. in post-silicon validation and debug, production test and diagnosis, as well as during in-field test and maintenance. Reliable access mechanisms for embedded instruments are therefore key to rapid chip development and secure system maintenance. Reconfigurable scan networks defined by IEEE Std. P1687 emerge as a scalable and cost-effective access medium for on-chip instrumentation. The accessibility offered by reconfigurable scan networks contradicts security and safety requirements for embedded instrumentation. Embedded instrumentation is an integral system component that remains functional throughout the lifetime of a chip. To prevent harmful activities, such as tampering with safety-critical systems, and reduce the risk of intellectual property infringement, the access to embedded instrumentation requires protection. This thesis provides a novel, Physical Unclonable Function (PUF) based secure access method for on-chip instruments which enhances the security of IJTAG network at low hardware cost and with less routing congestion.
Continuous Mutation Testing in Modern Software Development

Modern software is being built in a continuously integrated fashion, in order to overcome the challenges that come with developing large software systems from many contributors. The cornerstone of continuous integration is the testing step, since it is supposed to protect the system from changes that might disrupt correct behavior. Mutation testing is a method that checks the fault finding capability of a test suite. Current CI settings do not implement a step that checks how thorough the test suite is. Therefore, the goal of this thesis has been to explore how mutation testing can be applied to changes under analysis in a continuous integration setting. Since there is no infrastructure to support this, in order to conduct our study we developed OPi+, a prototype tool for experimenting the infrastructure required for a continuous mutation testing approach. Using real-world systems for analysis, we give initial evidence of the continuous mutation testing usefulness in terms of costs and benefits when applied to realistic software changes. The empirical study is based on analysis performed on the entire commit history of the popular open source Java Maven systems. Through our study we defined 5 types of outcomes together with a continuous mutation testing behavior flow and additional analysis that streamlines current mutation testing practices. We showed not only that mutation testing in a CI environment requires significantly fewer resources but they are also within the limits required by a CI pipeline. Through our study we also identify unmutable code for which we propose appropriate unimplemented operator set. We also study the evolution of surviving mutants with regards to their impact on the systems` technical debt. In our study, we showed initial evidence that mutation testing can successfully be made compatible with a CI environment. We therefore propose a few ideas that could possibly further streamline continuous mutation testing.
A Typology for the Management of Engineering Activities Based on the Customer Order Decoupling Point Concept

2 The Costain Group, Costain House, Vanwall Business Park, Maidenhead, Berkshire, SL6 4BU Abstract The customer order decoupling point (CODP) is commonly used to develop a simplified range of supply chain structures, ranging from standardised ship-to-stock to customized 'engineer-to-order' supply chains. This paper focuses on the latter category, with the purpose being the exploration of CODP concepts in design and engineering activities. The methodology follows a two phase approach. In the first phase, a collaborative form of inquiry as the means for producing knowledge is adopted, whereby academics and practitioners co-operated to develop a conceptual framework. The second phase includes three exploratory case studies, using interviews and site visits to gather data. The framework results in a classification of nine potential engineering subclasses. Through the exploratory case studies insight is given into the subclasses.
On-Sensor Binarized Fully Convolutional Neural Network for Localisation and Coarse Segmentation

Current neural networks are compatible with high-performance GPU/CPUs. However, implementing neural networks on emerging embedded sensor for inference is challenging due to sensor’s unique hardware architecture and stringent computing resources. With this in mind, this work presents new methods to implement fully convolutional neural networks (FCNs) on Pixel Processor Array (PPA) sensors with many techniques to fully use the limited resources on sensor. Specifically, we, for the first time, design and train binarized FCN for both binary weights and activations using batchnorm, group convolution, and learnable threshold for binarization, producing networks small enough to be embedded on the focal plane of the PPA, with limited local memory resources, and using parallel elementary add/subtract, shifting, and bit operations only. We demonstrate the first implementation of an FCN on a PPA device, performing three convolution layers entirely in the pixel-level processors. We use this architecture to demonstrate inference generating heat maps for object segmentation and localisation at over 280 FPS using the SCAMP-5 PPA vision chip.

ABSTRACT The importance of Big Data and Artificial Intelligence in the fields of accounting and auditing is beyond doubt. However, to date, the influence of these technologies on these fields has yet to be uncovered, and the works that have analysed such influence are still scarce. In an attempt to describe the development of this research trend and to understand its future directions of development, this article develops a bibliometric analysis to identify the different research fronts associated with this emerging topic. Using co-word and bibliographic coupling techniques, this paper aims to expand and extend the knowledge on this research line, to describe the evolution of publication activity, and to identify the most representative authors and journals. The paper also offers insights into potential new directions and declining perspectives, while summing up the most relevant literature within a specific area.
Shallow water acoustic communications : how far are we from the channel capacity ?

This paper focuses on the capacity of the underwater acoustic communications (UAC) channel under realistic assumptions: time-varying multi-paths channel, modelled as a stochastic doubly-spread frequency-selective channel, unknown actual realization of the channel at both transmitter and receiver, constraints on both transmitted power (rms and/or peak) and available frequency bandwidth. The exact channel capacity under such assumptions is still unknown. Therefore, several bounds for this capacity are given and then numerically assessed for a few typical shallow water UAC channels. The main conclusion is that, even with the above comprehensive set of demanding assumptions, as far as the theoretical channel capacity is considered, transmission with higher than often now spectral efficiency (e.g. 2 to 4 bits/sec/Hz) appears as a reasonable objective in typical time-varying underwater acoustic communication channels, providing SNR about 15 to 20 dB.

Wound Healing Properties and Antimicrobial Effects of Parkia clappertoniana Keay Fruit Husk Extract in a Rat Excisional Wound Model

Background Parkia clappertoniana Keay (Family: Fabaceae) (P. clappertoniana) fruit husk is commonly used in northern Ghana for wound treatment. However, this folk claim remains to be confirmed scientifically. Objective This study investigated wound healing and antimicrobial effects of P. clappertoniana fruit husk extract (PCFHE) by using excision wound model in rats. Materials and Methods After preparation and phytochemical analysis of PCFHE, it was reconstituted in purified water and emulsifying ointment yielding a wound healing formula (0.3, 1, and 3%). Excision wounds were established in healthy male Sprague-Dawley rats (aged 8-10 weeks; weighing 150–200 g). Rats were randomly assigned into six groups (model, 1% silver sulfadiazine [SSD], vehicle, and PCFHE [0.3, 1, and 3%, respectively]) and topically treated daily until complete wound healing. The endpoints (period of epithelialization, wound contraction, collagen content, erythema index, oedema index, inflammatory cell infiltration, and antimicrobial activity) were assessed for all groups. Minimum fungicidal concentration (MFC), minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and time-kill were assessed. Results Quercetin and catechin were detected in PCFHE. Compared to model and vehicle groups, PCFHE-treatment groups improved wound healing and antimicrobial (MBC, MFC, and MIC) endpoints. PCFHE demonstrated bacteriostatic and fungicidal effects against identified wound contaminants (Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, and Candida albicans). Conclusion P. clappertoniana fruit husk possesses wound healing and antimicrobial effects in excisional wounds in rats that confirms its folk use, and the reported pharmacological properties of PCFHE are attributable to its quercetin and catechin phyto-constituents.

­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­The aim of this study was to analyse the influence of temperature on electrical characteristics of crystalline and amorphous photovoltaic (PV) modules in outdoor conditions at Nawabshah. The experimental setup was made over the roof of the departmental building. The climatic conditions of site were recorded with the help of HP-2000 Professional Weather Station in three different timings of the day, i.e. morning, noon and evening. The electrical characteristics of the PV modules were recorded with Prova-210 and module temperatures with Prova-830. The maximum intensity of global solar radiation was recorded at noon and ambient temperature in the evening and the relative humidity in the morning hours. It was observed that amorphous module got 0.7°C, 1.0°C and 1.6°C more average temperature than polycrystalline, thin film and monocrystalline modules respectively. The average maximum measured open-circuit voltage was noted from amorphous with 96.7% and minimum from thin film with 81.3% of their respective values on standard conditions, whereas, the average maximum recorded short-circuit current was produced by thin film with 64.9% and minimum by amorphous with 51.4%. The average maximum power was produced by polycrystalline and minimum by amorphous module. It was discovered that the crystalline PV modules gave more fill factor than thin film and amorphous module.Article History: Received January 6th 2018; Received in revised form May 5th 2018; Accepted May 26th 2018; Available onlineHow to Cite This Article: Jatoi, A.R. , Samo, S.R. and Jakhrani, A.Q.
