Naïve subjects performed a direct out-of-the-box assembly and installation sequence for two models of hunters' tree stands. Their actions were timed and monitored in detail using an array of video cameras. After extensive analysis of their assembly errors and interactions with the packaged instructions, two alternative instruction sets were written, one with modified language, the other with additional user-friendly graphic material. Two additional groups of naïve subjects who assembled tree stands packed with these alternative instructions took significantly less time and made significantly fewer errors.

Ultrasonic thickness gauges are easy to operate and reliable, and can be used to measure a wide range of thicknesses and inspect all engineering materials. Supplementing the simple ultrasonic thickness gauges that present results in either a digital readout or as an A-scan with systems that enable correlating the measured values to their positions on the inspected surface to produce a two-dimensional (2D) thickness representation can extend their benefits and provide a cost-effective alternative to expensive advanced C-scan machines. In previous work, the authors introduced a system for the positioning and mapping of the values measured by the ultrasonic thickness gauges and flaw detectors (Tesfaye et al. 2019). The system is an alternative to the systems that use mechanical scanners, encoders, and sophisticated UT machines. It used a camera to record the probe’s movement and a projected laser grid obtained by a laser pattern generator to locate the probe on the inspected surface. In this paper, a novel system is proposed to be applied to flat surfaces, in addition to overcoming the other limitations posed due to the use of the laser projection. The proposed system uses two video cameras, one to monitor the probe’s movement on the inspected surface and the other to capture the corresponding digital readout of the thickness gauge. The acquired images of the probe’s position and thickness gauge readout are processed to plot the measured data in a 2D color-coded map. The system is meant to be simpler and more effective than the previous development.

<P>Background/Objective: Information of protein subcellular localization is crucially important for both basic research and drug development. With the explosive growth of protein sequences discovered in the post-genomic age, it is highly demanded to develop powerful bioinformatics tools for timely and effectively identifying their subcellular localization purely based on the sequence information alone. Recently, a predictor called “pLoc-mEuk” was developed for identifying the subcellular localization of eukaryotic proteins. Its performance is overwhelmingly better than that of the other predictors for the same purpose, particularly in dealing with multi-label systems where many proteins, called “multiplex proteins”, may simultaneously occur in two or more subcellular locations. Although it is indeed a very powerful predictor, more efforts are definitely needed to further improve it. This is because pLoc-mEuk was trained by an extremely skewed dataset where some subset was about 200 times the size of the other subsets. Accordingly, it cannot avoid the biased consequence caused by such an uneven training dataset. </P><P> Methods: To alleviate such bias, we have developed a new predictor called pLoc_bal-mEuk by quasi-balancing the training dataset. Cross-validation tests on exactly the same experimentconfirmed dataset have indicated that the proposed new predictor is remarkably superior to pLocmEuk, the existing state-of-the-art predictor in identifying the subcellular localization of eukaryotic proteins. It has not escaped our notice that the quasi-balancing treatment can also be used to deal with many other biological systems. </P><P> Results: To maximize the convenience for most experimental scientists, a user-friendly web-server for the new predictor has been established at http://www.jci-bioinfo.cn/pLoc_bal-mEuk/. </P><P> Conclusion: It is anticipated that the pLoc_bal-Euk predictor holds very high potential to become a useful high throughput tool in identifying the subcellular localization of eukaryotic proteins, particularly for finding multi-target drugs that is currently a very hot trend trend in drug development.</P>

Background Several industry funded studies between 2001–2018 have compared the use of a single brand of baby wipes to cleansing with water and either cloth or cotton wool during nappy changes. All of these studies found that wipes were safe and effective from birth. Recommendations from these studies have included the need for brand or formula comparison but to date, no previous study has done this. Aims The ‘Baby skin integrity comparison survey’ (BaSICS) study was designed to compare three brands of baby wipes to determine if there was any difference in the incidence of irritant diaper dermatitis (IDD or nappy rash) during the first eight weeks of life. Methods Mothers who were allocated to a single brand of nappy but divided into three baby wipe allocation groups, collected and reported survey data on infant skin integrity during one nappy change daily with the use of a user-friendly smartphone application. Findings All brands of wipes were acceptable to mothers and safe and effective when cleaning during nappy changes. The brand containing the fewest ingredients showed a clinically significant advantage of fewer incidents of rash than the other two brands. Conclusion This study demonstrated that wipe formulation is a significant factor in prevention or reduction of IDD during the first eight weeks of life.

Abstract This paper deals mainly with some of the difficulties the translator might encounter when translating some culturally bound pieces of information. These would include the translation of some idioms, and some culturally bound concepts. The paper starts with definitions of translation, language and culture followed by an extensive analysis of the examples provided. All the examples are drawn from Arabic and English. The examples include the translation of some idioms which violate truth conditions, which are easily recognizable, and some others which may be translated either literally or idiomatically with obviously different results. Then the analysis moves to the translation of some culturally bound expressions from both Arabic and English. Here, we find examples that cannot be translated into the other language simply for lack of cultural equivalents. The skill and the intervention of the translator are most needed in this respect because above all translation is an act of communication. Résumé Cet article traite principalement de certaines difficultés que le traducteur peut rencontrer quand il traduit des textes d’information qui présentent un aspect culturel. Ces difficultés ont trait à certaines locutions idiomatiques et concepts culturels. L’article commence par définir la traduction, la langue et la culture, puis analyse en détail les exemples fournis. Tous les exemples sont tirés de l’arabe et de l’anglais. Ces exemples comprennent la traduction de certaines locutions idiomatiques qui trahissent les conditions de vérite et sont facilement reconnaissables, et de quelques autres qui peuvent etre traduites soit litteralement, soit de manière idiomatique, mais avec bien sur des résultats différents. Puis l’analyse passe à la traduction de certaines expressions de nature culturelle, en arabe et en anglais. Nous y trouvons des exemples qu’il est impossible de traduire dans l’autre langue, tout simplement parce qu’il leur manque des équivalents culturels. L’habileté et l’intervention du traducteur sont des plus nécéssaires dans ce cas, parce que la traduction est avant tout un acte de communication.

Keeping an interaction distance between 1 to 2 m is one of the health protocols during the COVID-19 pandemic. This attempt was made to reduce the spread of the Coronavirus. On the other hand, this health protocol activity is often overlooked, whether intentionally or not. According to the mechanism of the Coronavirus spreading in the form of droplets that comes out during communication, sneezing, or coughing, maintaining distance can be the best effort to minimize the transmission of this virus. Therefore, the availability of a simple, accurate and user-friendly physical distancing alarm system could be a solution in the implementation of this health protocol. In this study, a prototype of a physical distancing alarm based on a distance sensor and a microcontroller in the form of an identity card was developed. Several steps are conducted in developing of this system, namely designing the instrumentation system and testing the performance of the system. System performance is tested through variations in the distance and angle of the objects. The measurement results show that the system can detect objects in front of the sensor up to a distance of 2.8m and an angle of  for a distance of 1m. The measurement using different angles of objects was performed for objects on the left and right sides of the sensor. In addition, a warning alarm will be on when the distance of the object exceeds the allowed distance.

Participatory sensing is a revolutionary new paradigm where ordinary citizens voluntarily sense their environment using readily available sensor devices such as mobile phones and systematically study, and then reflect on and share this information using existing wireless networks. It provides data collection, processing, and dissemination opportunities for socially-responsible applications spanning environmental monitoring, intelligent transportation, and public health, which are often not cost-viable using dedicated sensing infrastructure. The uniqueness of the participatory sensing system lies in its data communication infrastructure which is constituted by the deliberate participation of community people. However, the potential lack of privacy of the participants in such system makes it harder to ensure their voluntary contribution. Thus preserving privacy of the individuals contributing data has introduced a key challenge in this area. On the other hand, data integrity is desired imperatively to make the service trustworthy and user-friendly. Different interesting approaches have been proposed so far to protect privacy that will encourage participation of the owners of data sources in turn.

Milk analyzer is a very useful instrument in the dairy industry. Feed is the principle cause of variation in the composition of fat, although several other factors are believed to influence. The fat concentration is most sensitive to dietary changes, followed by protein concentration; whereas the concentration of lactose, vitamins, Solid not fat (SNF), salts and other solid constituents do not respond to the dietary alterations. Analyzing the percentage of fat, SNF, protein and lactose are very important. There are two different type of milk analyzers are reported in this work. Both are low cost and user friendly milk analyzer. One is a milk analyzer using a constant phase element (CPE) sensor and it is a contact type. The other one is milk analyzer using ultrasound wave. The ultrasonic sensor is a noncontact type sensor. When ultrasound wave passed through the milk sample it is attenuated. The signal conditioning circuit is designed and the performance of milk analyzer is studied in this work. These two milk analyzers are inexpensive and easy to handle.

Abstract One of the problems for failure analysis (FA) is to perform power cycling to stress the motherboard in order to duplicate the failure. The other problem is the timing is not synchronizing correctly. For this purpose, a user-friendly with extra feature program called Failure Analysis Power Cycling Tool (FAPCT) was developed to resolve problems associated with power cycling and enhance the AC cycling tools, which is more suitable for FA purpose. With this hardware and software, the FAE is provided one more option to duplicate intermittent or other issues that need to do power cycling to capture the failure. The hardware cost is only about 600 USD, which is consider at the lower cost hardware for a FA tools to do power cycling although there is some limitation compare to some hardware available in the market.

Abstract This paper describes a generalisation of straight-line mechanisms of Tchebycheff-type. Tchebycheff considered symmetric four-bar mechanisms for which the part of the coupler curve used as an approximation for a straight line oscillates between two lines, so that one line is a tangent of the coupler curve in three points and the other is a tangent of the coupler curve in two points and intersects the coupler curve in two further points. The described synthesis methods allow the calculation of unsymmetric mechanisms which have the same characteristic oscillation and are also optimal in the sense of the approximation theory developed by Tchebycheff. The use of continuation methods not only enabled the solution of a classical kinematic problem and the possibility to synthesize straight-line mechanisms with desired characteristic values but also offers new possibilities for user-friendly software for kinematic synthesis.
