Measuring acceptability of machine translated enterprise content

This research measures end-user acceptability of machine-translated enterprise content. In cooperation with industry partners, the acceptability of machine translated, post-edited and human translated texts, as well as source text were measured using a user-centred translation approach (Suojanen, Koskinen and Tuominen 2015). The source language was English and the target languages German, Japanese and Simplified Chinese. Even though translation quality assessment (TQA) is a key topic in the translation field, academia and industry greatly differ on how to measure quality. While academia is mostly concerned with the theory of translation quality, TQA in the industry is mostly performed by making use of arbitrary error typology models where “one size fits all”. Both academia and industry greatly disregard the end user of those translations when assessing the translation quality and so, the acceptability of translated and un-translated content goes largely unmeasured. Measuring acceptability of translated text is important because it allows one to identify what impact the translation might have on the end user – the final readers of the translation. Different stakeholders will have different acceptability thresholds for different languages and content types; some will want high quality translation, others may make do with faster turnaround, lower quality, or may even prefer non-translated content compared with raw MT. Acceptability is defined as usability, quality and satisfaction. Usability, in turn, is defined as effectiveness, efficiency in a specified context of use (ISO 2002) and is measured via tasks recorded using an eye tracker. Quality is evaluated via a TQA questionnaire answered by professional translators, and the source content is also evaluated via metrics such as readability and syntactic complexity. Satisfaction is measured via three different approaches: web survey, post-task questionnaire, and translators’ ranking. By measuring the acceptability of different post-editing levels for three target languages as well as the source content, this study aims to understand the different thresholds users may have regarding their tolerance to translation quality, taking into consideration the content type and language. Results show that the implementation of light post-editing directly and positively influences acceptability for German and Simplified Chinese languages, more so than for the Japanese language and, moreover, the findings of this research show that different languages have different thresholds for translation quality.

Chemical modification of 2D materials using molecules and assemblies of molecules

ABSTRACT In this article, we discuss the recent progress on controlled structural modification of 2D materials by means of molecular functionalization, with a focus on scanning probe microscopy techniques for their characterization. For many practical applications of these novel materials, it is necessary to tune their electronic and optical properties, and molecule-based functionalization is a powerful approach to reach this. We discuss recent covalent and non-covalent approaches, for functionalization of graphene, transition metal dichalcogenides, black phosphorus, and hexagonal boron nitride. Nanostructuring approaches and their impact on 2D materials’ properties are highlighted. Graphical abstract
Enhanced bitmap indexes for large scale data management

Advances in technology have enabled the production of massive volumes of data through observations and simulations in many application domains. These new data sets and the associated queries pose a new challenge for efficient storage and data retrieval that requires novel indexing structures and algorithms. We propose a series of enhancements to bitmap indexes to make them account for the inherent characteristics of large scale datasets and to efficiently support the type of queries needed to analyze the data. First, we formalize how missing data should be handled and how queries should be executed in the presence of missing data. Then, we propose an adaptive code ordering as a hybrid between Gray code and lexicographic orderings to reorganize the data and further reduce the size of the already compressed bitmaps. We address the inability of the compressed bitmaps to directly access a given row by proposing an approximate encoding that compresses the bitmap in a hash structure. We also extend the existing run-length encoders of bitmap indexes by adding an extra word to represent future rows with zeros and minimize the insertion overhead of new data. We propose a comprehensive framework to execute similarity searches over the bitmap indexes without changes to the current bitmap structure, without accessing the original data, and using a similarity function that is meaningful in high dimensional spaces. Finally, we propose a new encoding and query execution for non-clustered bitmap indexes that combines several attributes in one existence bitmap, reduces the storage requirement, and improves query execution and update time for low cardinality attributes.
An Enhanced k-means Clustering Algorithm

As for the shortcomings of the k-modes algorithm in the representation of class, we present a method for the representation of class with summary information. A distance definition for mixed attributes is proposed in this paper. Based on the distance definition, we extend the k-means algorithm and present the k-summary algorithm. Theoretical analyses and experimental results demonstrate that the k-summary algorithm can create more accurate class results than the k-modes algorithm and the k-prototypes algorithm.

Improving the Performance of Paper Supercapacitors Using Redox Molecules from Plants

A supercapacitor made from organic and nature‐based materials, such as conductive polymers (PEDOT:PSS), nanocellulose, and an the organic dye molecule (alizarin), is demonstrated. The dye molecule, which historically was extracted from the roots of the plant rubia tinctorum, is here responsible for the improvement in energy storage capacity, while the conductive polymer provides bulk charge transport within the composite electrode. The forest‐based nanocellulose component provides a mechanically strong and nonporous network onto which the conductive polymer self‐organizes. The electrical and electrochemical properties of the material composition are investigated and prototype redox‐enhanced supercapacitor devices with excellent specific capacitance exceeding 400 F g−1 and an operational stability over >1000 cycles are demonstrated. This new class of supercapacitors, which in part are based on organic materials from plants, represents an important step toward a green and sustainable energy technology.

Analysis of Different Methods for Measuring the Performance of Database on Cloud Environment

Cloud computing become most adoptable technology over the past few years, it is widespread for both at organizational level or for the person who use the services that are offered in the cloud. There are several technocrats currently researched on cloud related issues and soon cloud represents the modern computing. The cloud gave the prospect for the enterprise and allowing them to center on their work by providing hardware and software solution without developing them own. Now a day the database has also moved to cloud computing so we will look into the fine points of database as a service and it’s servicing. While storing data on cloud there is a need to balance the load on datacenters because if user base always sends request on single data center then it becomes overloaded so load balancing techniques are applied to manage this problem. To manage geographic distribution in terms of computing servers and data workloads a tool termed as CloudAnalyst is used which is based on cloudsim technique. CloudAnalyst helps developers with the vision of distributing applications among cloud infrastructures. Currently tool having three algorithms for load balancing round robin, throttled load balancer, equally spread current execution and the proposed algorithm is weighted round robin which works better as comparison to round robin in various aspects.
Design of a bipedal walking robot

We present the mechanical design of a bipedal walking robot named M2V2, as well as control strategies to be implemented for walking and balance recovery. M2V2 has 12 actuated degrees of freedom in the lower body: three at each hip, one at each knee, and two at each ankle. Each degree of freedom is powered by a force controllable Series Elastic Actuator. These actuators provide high force fidelity and low impedance, allowing for control techniques that exploit the natural dynamics of the robot. The walking and balance recovery controllers will use the concepts of Capture Points and the Capture Region in order to decide where to step. A Capture Point is a point on the ground in which a biped can step to in order to stop, and the Capture Region is the locus of such points.
Why Do Young People Avoid Photo Tagging? A New Service Avoidance Scale

Despite the growing attention to the study of various issues concerning online self-presentation, little research has investigated the different reasons underlying the avoidance of online identity and presentation building features. Using a multistage investigation, this study has developed and validated a 25-item instrument for investigating the various reasons why young people avoid Facebook photo tagging. The instrument items were developed based on open-ended qualitative essays written by 141 Indian and Pakistani adolescents who use the Facebook photo-tagging service. From their qualitative responses, 38 items were first extracted and evaluated with 780 Indian adolescent photo taggers. This resulted in the development of a 25-item instrument which was reexamined a year later with 314 Indian adolescent and 106 young adult photo taggers. The study participants were recruited from India and Pakistan in order to address the criticism of previous Facebook research which is chiefly based on U.S.-only study samples. The developed instrument indicated six reasons: destruction of capital, dislike, worry, parental control, embarrassment, and personal appearance. The study results indicate that the developed instrument has a stable factorial structure, validity, and reliability over time. This new instrument offers various theoretical and practical implications for scholars engaged in research involving computer-mediated communication, online self-presentation, and young people.
Novel Ordered Rocksalt-Type Lithium-Rich Li2Ru1–xNixO3−δ (0.3 ≤ x ≤ 0.5) Cathode Material with Tunable Anionic Redox Potential

In this work, a series of ordered rocksalt (OR) type Li-rich Li2Ru1–xNixO3−δ (LRNxO, 0.3 ≤ x ≤ 0.5) are successfully synthesized and investigated for the first time. X-ray diffraction and neutron powder diffraction patterns exhibit an obvious phase transition from layered to an OR structure as the Ni content gradually increases from x = 0 to x = 0.5, which leads to different electrochemical behaviors. In the case of OR-LRN0.4O, an ∼350 mV decrease of the oxygen oxidation potential compared with Li2RuO3 (LRO) is observed from around 4.2 to 3.85 V, which is confirmed by both X-ray photelectron O 1s spectra and dQ/dV results. The role of Ni substitution on the oxygen redox reaction is studied by first-principles calculations, and it is concluded that the formation of the OR structure caused by Ni substitution is the main reason for lowering the oxygen oxidation potential. In addition, the average discharge voltage of OR-LRN0.4O is also enhanced compared with LRO. This work provides a novel innovative strateg.
The effect of creasing method and tooling on the geometry of formed creases in the creasing process of coated and uncoated paperboard

Creasing is a method, which is used to produce grooves in fibre-based materials, such as multi-layer paperboard or composite materials such as polymer-coated multi-layer paperboard. These grooves act as folding lines, which guide and control the subsequent folding of the material. The formation of creases is crucial for the functionality of produced blanks in subsequent processes, such as press-forming where the creases have an effect on the formability of materials. The plastic deformation and geometry of creases for polymer-coated and uncoated multi-layer paperboard were investigated using two different creasing processes, flatbed die cutting and a digital creasing and cutting table with a creasing wheel. The presence and dimensions of the creasing grooves were varied to investigate the effect on the formed shapes. A wide area 3D measurement system was used to analyse and measure (Figure 1) the dimensions of the formed creases. The analysis occurred in machine-direction (MD) of the fibre-orientation in the formed materials. The results show that that the used process and tool selection has a clear effect on the formed shapes.
Surface engineering and applications of nanodiamonds in cancer treatment and imaging

Nanodiamonds (NDs) are emerging as a promising platform for theranostic particles because they unite a spectrum of important properties into a single agent, including facile synthesis, small size, inertness, rich surface functional groups, biocompatibility, stable fluorescence and long fluorescence lifetime. These unique properties have stimulated the application of NDs in cancer treament and imaging. The majority of these applications rely on the rational engineering of the particle surface, as the surface plays a critical role in carrying bioactive molecules, resisting aggregation and constructing composite materials. In this review, recent developments of functionalising NDs for cancer treatment and imaging purposes are discussed. A brief introduction in the structure of NDs and properties of NDs will be given, followed by a summary of various surface functionalisation methods. The latter part is organised in three subsections: NDs coated with bioactive compounds, NDs coated with synthetic polymers and NDs/inorganic composites.
Characteristics optimization of composite phase-change wall during intermittent heating process

The indoor thermal environment under an intermittent heating condition can be maintained by rationally utilizing the heat storage and release processes of the composite phase-change wall (composite-PCW), leading to heating time and energy consumption reductions. In order to optimize its heat storage and release processes, the influences of different parameters on the dynamic thermal processes of composite-PCW were studied, including the position and thickness of phase-change material (PCM), phase transition temperature, phase-change latent heat, and PCM thermal conductivity, according to two typical intermittent conditions summarized by experimental data. With large heat storage efficiency η and small heat loss rate ε, the optimized composite-PCW that was adaptive for intermittent heating was the composite-PCW with 10 mm PCM integrated to the wall inside. Its phase-transition temperature was 19–20 °C (66.2–68 °F), the phase-change latent heat was 220 kJ/kg (95.58 btu/lb), and the thermal conductivity was 0.4 W/(m·K) (0.23 btu/(ft·h·°F)) at liquid states and 0.8 W/(m·K) (0.46 btu/(ft·h·°F)) at solid states.
