Evaluation on Effectiveness of CVD and PVD Coated Tools during Dry Machining of Incoloy 825

With wide applications of nickel based superalloys in strategic fields, it has become increasingly necessary to evaluate the performance of different advanced cutting tools for machining such alloys. With a view to recommend a suitable cutting tool, the present work investigated various machinability characteristics of Incoloy 825 using an uncoated tool, chemical vapor deposition (CVD) of a bilayer of TiCN/Al2O3, and physical vapor deposition (PVD) of alternate layers of TiAlN/TiN coated tools under varying machining conditions. The influence of cutting speed (51, 84, and 124 m/min) as well as feed (0.08, 0.14, and 0.2 mm/rev) was comparatively evaluated on surface roughness, cutting temperature, cutting force, coefficient of friction, chip thickness, and tool wear using different cutting tools. Although the CVD coated tool was not useful in decreasing surface roughness and temperature, a significant reduction in cutting force and tool wear could be achieved with the same coated tool under a high cutting speed of 124 m/min. On the other hand, the PVD coated tool outperformed the other tools in terms of machinability characteristics. This might be attributed to the excellent antifriction and antisticking property of TiN and good toughness due to the multilayer configuration in combination with a thermally resistant TiAlN phase. Adhesion, abrasion, edge chipping, and nose wear were the prominent wear mechanisms of the uncoated tool, followed by the CVD coated tool. However, remarkable resistance to such wear was evident with the PVD TiAlN/TiN multilayer coated tool.
Audit quality indicators: perceptions of junior level auditors

In an effort to develop an audit quality (AQ) framework specific to the US audit market, the Public Company Accounting Oversight Board (PCAOB) recently issued a concept release proposing 28 audit quality indicators (AQIs) along three dimensions: audit professionals, audit process and audit results. Using AQIs initially proposed by the PCAOB, as well as AQIs suggested by prior literature, the authors solicit perceptions from junior level (senior and staff) auditors to investigate the current state of practice along many of the AQIs relating to audit professionals and audit process.  In the study, 78 junior level auditors responded to the survey.  An analysis of the responses suggests auditors engage in activities and audit firms promote conditions that at times improve, and at other times, reduce audit quality. The authors find that individual auditors' perceptions differ across experience level, gender and audit firm size for certain AQIs.  The study is useful to the PCAOB because it provides insights to help assess the value of potential AQIs in differentiating AQ. The study is also useful to other regulators because it describes audit staff and seniors' perceptions of apparent firm and auditor compliance with accounting and auditing standards. Practitioners should find this information useful in helping to identify possible root causes of audit deficiencies, a challenge put forth to firms by the PCAOB.  This study provides academia with evidence on AQ from practicing auditors, which informs existing and future research along. The study complements existing work by showing how individual auditor characteristics (experience and gender) at the junior levels may impact AQ in practice
The expectation differences among stakeholders in the financial valuation fitness of auditors

The purpose of this paper is to investigate if there is an expectation gap among accounting academics, accounting practitioners, and users of financial statements in the financial valuation fitness of auditors. Complex reporting standards and current market expectations have the potential to create differences between what third party users consider to be the responsibilities of the auditor and what auditors believe to be their responsibilities in auditing fair value estimates.  This study surveys the perceptions of accounting academics, accounting practitioners, and users of financial statements and the degree to which an expectation gap exists in the financial valuation fitness of auditors. Survey respondents chose from a five point Likert scale ranging from "strongly agree" to "strongly disagree."  This paper proposes two hypotheses. The results for all nine survey items have provided significant evidence that there is a difference in the expectation of
Analysis of protein coding genetic variation in 60,706 humans
Venue: Nature

Large scale reference data sets of human genetic variation are critical for the medical and functional interpretation of DNA sequence changes. Here we describe the aggregation and analysis of high quality exome (protein coding region) DNA sequence data for 60,706 individuals of diverse ancestries generated as part of the Exome Aggregation Consortium (ExAC) This catalogue of human genetic diversity contains an average of one variant every eight bases of the exome, and provides direct evidence for the presence of widespread mutational recurrence. We have used this catalogue to calculate objective metrics of pathogenicity for sequence variants, and to identify genes subject to strong selection against various classes of mutation; identifying 3,230 genes with near complete depletion of predicted protein truncating variants, with 72% of these genes having no currently established human disease phenotype. Finally, we demonstrate that these data can be used for the efficient filtering of candidate disease causing variants, and for the discovery of human 'knockout' variants in protein coding genes.

A Bidirectional Nonisolated Multi Input DC DC Converter for Hybrid Energy Storage Systems in Electric Vehicles
Venue: IEEE Transactions on Vehicular Technology

To process the power in hybrid energy systems using a reduced part count, researchers have proposed several multiinput dc dc power converter topologies to transfer power from different input voltage sources to the output. This paper proposes a novel bidirectional nonisolated multi input converter (MIC) topology for hybrid systems to be used in electric vehicles composed of energy storage systems (ESSs) with different electrical characteristics. The proposed converter has the ability to control the power of ESSs by allowing active power sharing. The voltage levels of utilized ESSs can be higher or lower than the output voltage. The inductors of the converter are connected to a single switch; therefore, the converter requires only one extra active switch for each input, unlike its counterparts, hence resulting in reduced element count. The proposed MIC topology is compared with its counterparts concerning various parameters. It is analyzed in detail, and then, this analysis is validated by simulation and through a 1 kW prototype based on a battery/ultracapacitor hybrid ESS.
Mobile Application Quality Assurance: Reading Scenarios as Inspection and Testing Support
Venue: 2016 42th Euromicro Conference on Software Engineering and Advanced Applications (SEAA)

The quality of mobile applications is one essential factor for their success because users discard applications of insufficient quality immediately. Due to the peculiarities of mobile application development, there is a need for a quality assurance approach that focuses on its challenges. Missing mobile specific testing methods and time and effort constraints are challenges that mobile application developing companies have to cope with nowadays. We therefore propose a mobile specific approach that supports doing inspections and testing by reading scenarios that focus on typical mobile issues. Scenarios providing detailed support for inspectors regarding mobile specific problems are used during an inspection to check quality early and produce mobile specific test cases that can be used directly during testing. In order to reduce the effort for quality assurance, automation is used. Hence, our contribution in this paper is an approach for generating those scenarios. As proof of concept, we implemented a scenario generator that realizes the automated provision of scenarios considering the concrete project scope. This is intended to enable the use of reading scenarios in order to focus mobile application quality assurance.
Run Time Application Repartitioning in Dynamic Mobile Cloud Environments
Venue: IEEE Transactions on Cloud Computing

As mobile computing increasingly interacts with the cloud, a number of approaches, e.g. MAUI and CloneCloud, have been proposed, aiming to offload parts of the mobile application execution to the cloud. To achieve a good performance by using these approaches, they particularly focus on the application partitioning problem, i.e. to decide which parts of an application should be offloaded to the cloud and which parts should be executed on mobile devices such that the execution cost is minimized. Most works on this problem assume that the offloading cost of each part of the application remains the same as the application is running. Unfortunately, this assumption does not hold in dynamic mobile cloud environments, where the device and network connection status may fluctuate, and thus affects the offloading cost. With the varying offloading cost, the one time partitioning of the application may yield significant performance degradations. In this paper, we study application repartitioning problem which considers updating the partition periodically during the course of application execution. We first propose a framework for run time application repartitioning in dynamic mobile cloud environments. Based on this framework, we take the dynamic network connection to clouds as a case study, and design an online solution, Foreseer, to solve the mobile cloud application repartitioning problem. We evaluate our solution based on real world data traces that are collected in a campus WiFi hotspot testbed. The result shows that our method can achieve significantly shorter completion time over previous approaches.
Patients' and healthcare providers' perceptions of a mobile portal application for hospitalized patients
Venue: BMC Medical Informatics and Decision Making

BackgroundHospital based patient portals have the potential to better inform and engage patients in their care. We sought to assess patients' and healthcare providers' perceptions of a hospital based portal and identify opportunities for design enhancements.MethodsWe developed a mobile patient portal application including information about the care team, scheduled tests and procedures, and a list of active medications. Patients were offered use of tablet computers, with the portal application, during their hospitalization. We conducted semi structured interviews of patients and provider focus groups. Text from transcribed interviews and focus groups was independently coded by two investigators using a constant comparative approach. Codes were reviewed by a third investigator and discrepancies resolved via consensus.ResultsOverall, 18 patients completed semi structured interviews and 21 providers participated in three focus groups. Patients found information provided by the portal to be useful, especially regarding team members and medications. Many patients described frequent use of games and non clinical applications and felt the tablet helped them cope with their acute illness. Patients expressed a desire for additional detail about medications, test results, and the ability to record questions. Providers felt the portal improved patient engagement, but worried that additional features might result in a volume and complexity of information that could be overwhelming for patients. Providers also expressed concern over an enhanced portal's impact on patient provider communication and workflow.ConclusionsOptimizing a hospital based patient portal will require attention to type, timing and format of information provided, as well as the impact on patient provider communication and workflow.
An experimentally validated network of nine haematopoietic transcription factors reveals mechanisms of cell state stability
Venue: eLife

Transcription factor (TF) networks determine cell type identity by establishing and maintaining lineage specific expression profiles, yet reconstruction of mammalian regulatory network models has been hampered by a lack of comprehensive functional validation of regulatory interactions. Here, we report comprehensive ChIP Seq, transgenic and reporter gene experimental data that have allowed us to construct an experimentally validated regulatory network model for haematopoietic stem/progenitor cells (HSPCs) Model simulation coupled with subsequent experimental validation using single cell expression profiling revealed potential mechanisms for cell state stabilisation, and also how a leukaemogenic TF fusion protein perturbs key HSPC regulators. The approach presented here should help to improve our understanding of both normal physiological and disease processes.
Solvothermal synthesis of 3D leaf like a Fe2O3 and its gas sensing properties research

Abstract 3D leaf like Alpha iron oxide (a Fe2O3) nanostructure and other nanomorphologies were fabricated by adding different ethanol content in ethanol water mixed solvent under a simple solvothermal route. The structures and morphologies of nanostructures were characterized by X ray diffraction (XRD) field emission electron scanning microscopy (FESEM) and transmission electron microscopy (TEM) Their morphologies and gas sensing properties were mainly studied. The sensor synthesized in 80 vol% ethanol water as the solvent exhibited lower operating temperature (260 degC) higher response and shorter Response/recovery time (about 8 s and 9 s) The results indicated that 3D leaf like iron oxide (a Fe2O3) nanostructure was a potential candidate for fabricating effective acetone sensor.

An End to end Approach to Learning Semantic Frames with Feedforward Neural Network
Venue: NAACL

We present an end to end method for learning verb specific semantic frames with feedforward neural network (FNN) Previous works in this area mainly adopt a multi step procedure including part of speech tagging, dependency parsing and so on. On the contrary, our method uses a FNN model that maps verbspecific sentences directly to semantic frames. The simple model gets good results on annotated data and has a good generalization ability. Finally we get 0.82 F score on 63 verbs and 0.73 F score on 407 verbs.
How much sugar is hidden in drinks marketed to children? A survey of fruit juices, juice drinks and smoothies
Venue: BMJ Open

To investigate the amount of sugars in fruit juices, juice drinks and smoothies (FJJDS) marketed to children.  We surveyed the sugars content (per 100 ml and standardised 200 ml portion) of all FJJDS sold by seven major UK supermarkets (supermarket own and branded products) Only products specifically marketed towards children were included. We excluded sports drinks, iced teas, sugar sweetened carbonated drinks and cordials as being not specifically marketed towards children.  We identified 203 fruit juices (n=21) juice drinks (n=158) and smoothies (n=24) marketed to children. Sugars content ranged from 0 to 16 g/100 ml. The mean sugars content was 7.0 g/100 ml, but among the 100% fruit juice category, it was 10.7 g/100 ml. Smoothies (13.0 g/100 ml) contained the highest amounts of sugars and juice drinks (5.6 g/100 ml) contained the lowest amount. 117 of the 203 FJJDS surveyed would receive a Food Standards Agency 'red' colour coded label for sugars per standardised 200 ml serving. Only 63 FJJDS would receive a 'green' colour coded label. 85 products contained at least 19 g of sugars a child's entire maximum daily amount of sugars. 57 products contained sugar (sucrose) 65 contained non caloric sweeteners and five contained both. Seven products contained glucose fructose syrup.  The sugars content in FJJDS marketed to children in the UK is unacceptably high. Manufacturers must stop adding unnecessary sugars and calories to their FJJDS.

So, make a good wine is a important part of the work, but after this is necessary to give it the presentation it deserves, communicating accurately to consumers and have in mind that digital marketing activities are in a state of evolutionary development, where new trends are likely to occur rapidly and wineries have to adapt.
Effects of three additives on the removal of perfluorooctane sulfonate (PFOS) by coagulation using ferric chloride or aluminum sulfate.
Venue: Water science and technology a journal of the International Association on Water Pollution Research

Perfluorooctanesulfonic acid and its salts (PFOS) are emerging contaminants with long half lives in water and human bodies. Accordingly, PFOS removal from water streams is required for controlling the PFOS pollution. To provide a simple PFOS separation technology, effects of three additives, powdered activated carbon (PAC) gelatin, and cetyltrimethylammonium bromide (CTAB) on the PFOS removal by coagulation with ferric chloride or aluminum sulfate were investigated in this study. As a result, coagulation with PAC or CTAB addition was effective in the PFOS removal, though the conventional coagulation and coagulation with gelatin addition were ineffective. A PFOS removal efficiency of over 90% was observed for the CTAB dose of over 1.6 mM (0.58 mg/L) and for the PAC dose of over 40 mg/L, and that of over 95% was achieved by the CTAB dose of over 2.4 mM (0.87 mg/L) when the initial PFOS concentration was 1.84 mM. The positive effect of CTAB would be caused by micelle formation, which was enhanced by both the association of hydrophobic tails and the electrostatic attraction of hydrophilic heads of PFOS and CTAB. Thus, a linear cationic surfactant of CTAB was concluded to be an effective additive for the PFOS removal by coagulation.
Evaluation of machine learning classifiers for mobile malware detection
Venue: Soft Comput.

Mobile devices have become a significant part of people's lives, leading to an increasing number of users involved with such technology. The rising number of users invites hackers to generate malicious applications. Besides, the security of sensitive data available on mobile devices is taken lightly. Relying on currently developed approaches is not sufficient, given that intelligent malware keeps modifying rapidly and as a result becomes more difficult to detect. In this paper, we propose an alternative solution to evaluating malware detection using the anomaly based approach with machine learning classifiers. Among the various network traffic features, the four categories selected are basic information, content based, time based and connection based. The evaluation utilizes two datasets: public (i.e. MalGenome) and private (i.e. self collected) Based on the evaluation results, both the Bayes network and random forest classifiers produced more accurate readings, with a 99.97 true positive rate (TPR) as opposed to the multi layer perceptron with only 93.03 on the MalGenome dataset. However, this experiment revealed that the k nearest neighbor classifier efficiently detected the latest Android malware with an 84.57 true positive rate higher than other classifiers.

Venue: 2016 4th Intl Conf on Applied Computing and Information Technology/3rd Intl Conf on Computational Science/Intelligence and Applied Informatics/1st Intl Conf on Big Data, Cloud Computing, Data Science Engineering (ACIT CSII BCD)

Parallel multi dimensional indexing system was proposed for big data analysis. The insertion and the retrieval performances were evaluated through randomly distributed data with three distribution schemes: area expansion, overlap, and proximity. This paper evaluates insertion and retrieval performances of this system through skewed data with the round robin method as well as three distribution schemes. It is experimentally clarified that the round robin method has good retrieval performance to randomly distributed data. It is also experimentally clarified that the proximity method has good retrieval performance especially for skewed data.
