A DSL for business intelligence monitoring

Social media has provided the business community with a unique and unprecedented opportunity to engage with their customers, critics, competitors, etc. Yet, this comes at the costs of continuously monitoring the various fora where the business name may be mentioned, where questions may be posted, where products may be compared, etc. Effectively dealing with social media in a world where a maximum of a few hours is the expected response time, is a challenging task. Focusing in particular on Facebook, a typical business would have its own page as well as a strong interest in pages on which their products may be discussed or advertised. Typical events which are relevant for a business might include any mention of the brand or a product, an advertising post by a competitor, a comment by a customer (particularly if negative or if a question), and so on. To make the task of checking for these events manageable, dashboards [1, 3, 2] are available allowing users to specify events of interest so that a notification is received when such an event is detected (e.g., a notification when more than five comments are awaiting a response). The problem with existing tools is that while they allow the specification of a number of events of interest, they do not offer the flexibility which might be required by the business in question. For example one might want to prioritise the notifications in order of urgency (e.g., a comment from a new customer might is given precedence over that of an existing customer); alternatively one might want to group them into batches (e.g., a notification per five comments unless a comment has been posted for more than three hours). Such flexibility usually comes at the price of a tailor-made solution which is generally expensive both if developed in house or by a third party. One way of allowing a high degree of flexibility while providing an off-the-shelf solution would be to present a simple interface which would allow a business intelligence analyst the flexibility to express the desired events for notification. These would in turn be automatically compiled into Facebook monitors without any further human intervention. While an automated compiler would struggle to handle natural language descriptions and a non-technical business analyst would struggle with a programming language, a domain-specific language presented to the user as a controlled natural language (CNL) [6] may act as an intermediary: it provides the feel of a natural language but constraints the writer to particular keywords and patterns. Furthermore, using standard techniques to allow the user to write their scripts using particular user-interfaces (e.g. pull-down menus or fridge magnet style) bypasses the problem of syntax errors, thus making their writing more accessible to a non-technical audience. Based on interviews with two business analysts, such a CNL should allow the user to specify patterns such as: (i) Create an alert when the service page has a post and the post contains the keywords fridge, heater, and freezer. (ii) Create an alert when my
‘Confident’ and ‘hot’ or ‘desperate’ and ‘cowardly’? Meanings of young men’s sexting practices in youth sexting culture

ABSTRACT Young men tend to be constructed as being at low risk of harm and able to extract value from sexting, compared to young women. Drawing upon findings from a qualitative study exploring practices and perceptions of sexting among 14–18 year-old participants in southeast England, I discuss the meanings and norms surrounding young men’s sexting practices. I outline how these meanings and norms underpinned perceptions regarding the value available to young men through sexting. Young men were not, however, equally able to extract value and social capital through sexting, and participants discussed examples of the social shaming of young men who sext. I discuss how young men took up diverse positions with regard to masculine heterosexuality within youth sexting culture, in which they reworked and challenged the ideals and assumptions inherent to ‘hegemonic masculinity’. I draw two conclusions: firstly, it should not be assumed that young men are inherently able to gain value through sexting; secondly, narratives of risk and shame may mean that while young men distance themselves from sexting, gendered assumptions and inequalities regarding bodily and sexual expression remain.
Burnout and engagement in higher education : Relationships with social support, guidance and sense of belonging

There has been increasing research attention on wellbeing of students in higher education both in Finland and internationally. Because of its goal-oriented nature, higher education resembles working in many ways. Thus, research on students ́ wellbeing has started utilizing concepts derived from occupational research. Burnout and study engagement are concepts that are being used in research on both lower educational levels and higher education. Burnout describes feelings of exhaustion, cynicism and inadequacy experienced when demands of studying exceed available resources. Engagement on the other hand means feeling vigorous, dedicated and absorbed in studying and arises when demands and resources are better balanced. The goal of this thesis was to increase understanding of social resources that can guard against the negative effects of demands and foster engagement in higher education. It investigated how social support, guidance and counselling from the educational institution and sense of belonging to studying related groups are related to burnout and engagement experienced by students. The data for this study was the Finnish Student Health Service ́s Student Health Survey from 2016, which is a representative sample of students in universities and universities of applied sciences in Finland (N=3110). Burnout symptoms were measured using the SBI-9 measure and engagement using the Schoolwork Engagement Scale. The total scores on these two scales were analyzed together with social support, guidance and counselling and sense of belonging to studying related groups. Pearson ́s correlation coefficients were obtained to reveal the bivariate associations of these variables followed by two hierarchical regression analyses on burnout and engagement individually. All of the social resources were included as predictors in these models and the stage of studies, gender and feeling of being in the right field of study were controlled for as background variables. The results supported both hypotheses and existing literature. It was found that those students who were able to talk about their matters with someone, had received guidance to their studies and felt like they belong to studying related groups had lower levels of burnout symptoms. Similarly, students with sufficient social resources were more engaged in their studies. The results indicate that social resources are an important factor in wellbeing of higher education students. Future research should continue to further study these resources using more accurate measures incorporating different types of social support or different groups in the educational context.
A Coil for Wireless Power Transmission by Using Sewing Technique with Litz Wire

A Coil for wireless power transmission was manufactured by using of sewing techniques. The sewing methods and electric characteristics were described. The coils were sewn with a cross stitch. The inductance and loss resistance of the sewn coils was measured. It is assumed that the power receiving side coil is attached to biomedical implantable devices. The coupling coefficient between the power receiving side coil and the sewn coil was measured. The maximum coupling coefficient was 0.75. The maximum efficiency of 75.0% was obtained when the coupling coefficient was maximum. Inverter and rectifier were attached the circuit and the load voltage was measured. The maximum load voltage was 4.77 V.
Coded Signals for High Frequency Ultrasound Imaging

Degeneration of articular cartilage is known as a serious and painful knee disease seriously affecting people in all ages. The disease also marks the presence of osteoarthritis which is a complex musculoskeletal disorder. A successful assessment of the degeneration status is of great importance for estimating osteoarthritis progression, and thereby beneficial for implementing clinical treatments. Ultrasound has played a vital role in imaging the articular cartilage since it is capable of providing distinct information of important cartilage structures. However, various types of noise in ultrasound signals (e.g. clutter noise) are known to limit the quality of ultrasound images, especially at high frequencies where wave attenuation becomes severe. The possibility for improving the signal to noise ratio (SNR) by using coded signals is therefore the motivation behind this thesis, with the main objective is to investigate suitable codes and compression methods for cartilage imaging. The main focus of this thesis has been put on coded ultrasound signals and related signal processing methods. Transducers made from two different piezoelectric materials (PZT and PVDF) are used to image a thick cartilage sample. For each transducer, three different waveforms (Ricker wavelet, Gaussian chirped, and a 13-bit Barker) are used to excite the ultrasonic transducers. Two different wave compression methods (Matched filtering and Wiener filtering) are also explored to decode the signals received by transducers. Ahead of processing the received signals, a time calibration was used to compensate for sample tilting, yielding an improved precision in the phase/time delay. A maximum method and a center of mass method were used for calibration. The results from the experimental work show that both Chirp coded signals and Barker coded signals work well in improving the SNR, and that both transducers are able to produce high quality images of the cartilage sample. For the situations using coded excitation signals, however, the PZT transducer has high requirement for excitation repetition frequency because of its built-in delay line. Different time calibration methods have their own applicable conditions. Matched filter and Wiener filter both perform well for decoding, but the “noise” parameter in the Wiener filter has to be adjusted carefully to produce reasonable results.
Fiber optic tram vehicle detector

This article describes a compact trackside low-cost measuring sensor with basic advantages such as immunity to electromagnetic interference and ability to remotely evaluate information (the tested distance was 3000 m). The proposed sensor is constructed to detect vibration-acoustic responses caused by tram vehicles. The sensor was tested in real tram traffic. Over a period of six months, a total of 1435 tram vehicles were recorded (different types of tram vehicles) with 100 % detection success. The massive expansion of optical cables along the railways provides our system could be directly connected to as well as being remotely monitored and evaluated.
Optimizing Naïve Bayes algorithm for SMS Spam Filtering on mobile phone to reduce the consumption of resources

Mobile phone is a embedded system with limited energy, memory and computing ability. The traditional SMS spam filtering algorithms only focused on the accuracy rate of spam filters and did not consider the consumption of mobile phone’s hardware resources. This paper proposes an optimized Naïve Bayes SMS Spam filtering algorithm, the main purpose is to reduce the consumption of hardware resources and reflect user’s individual preference. A feature library is designed to save weight of features, conditional probabilities and prior probabilities. The filtering algorithm is divided into a feature library updating algorithm and an online SMS filtering algorithm. The feature library is updated regularly by the feature library updating algorithm. The feature library updating algorithm does not need to run immediately, and can be performed in free time of mobile application or copied to PC client asynchronously. The online SMS filtering algorithm running on a mobile phone performs only the minimum amount of work which does not require much resources. It can be quickly adapted to the changing of user’s preference. Experimental results show that the algorithm can improve the speed of classification while maintaining a high classification accuracy. it takes up less storage space and can be used on common mobile platforms.
Separating the regular from the idiosyncratic: An object-oriented lexical encoding of MWEs using XMG

We present a general object-oriented approach to the lexical encoding of multi-word expressions (MWEs) that is couched into the framework of eXtensible MetaGrammar (XMG). We think that XMG provides the flexibility and power needed to account for both regular and idiosyn-cratic aspects of MWEs, which enables the lexicographer to encode MWEs in a transparent and yet factorized way. We compare XMG with two other existing formats for lexical encoding of MWEs, DuELME and Walenty, which have been coupled with real-size grammars and provide mechanisms to avoid description redundancy. We claim that XMG offers additional facilities that reinforce the virtues of its competitors. In this work we confine ourselves to syntax and morphology.
Marginal Adaptation of Lithium Disilicate Endocrowns with Different Cavity Depths and Margin Designs

to study effect of different preparation designs on the marginal adaptation of lithium disilicate endocrowns. Materials and methods: Twenty human mandibular molars were selected to conduct the present study. All teeth were randomly divided into 2 groups (n=10 each) according to the preparation design of endocrown with two coronal cavity depths: Group (2D): Endodontically treated teeth with 2mm depth intra-coronal cavity preparation . Group (4D): Endodontically treated teeth with 4mm depth intra-coronal cavity preparation. Samples of each group were further subdivided into 2 subgroups (n=5 each) according to the preparation’s margin configuration: Subgroup (B): preparations with butt-joint margin configuration. Subgroup (S): preparations with 90o shoulder margin configuration. All prepared teeth were restored using IPS e.max Press endocrowns. The vertical marginal adaptation was measured after cementation using a Stereomicroscope. Measurements were made at twenty points for each crown. The recorded data were collected, tabulated and statistically analyzed. Results: shoulder finish line marginal preparation recorded lower vertical marginal gap values than butt joint marginal preparation. 2mm intracoronal cavity depth extension recorded lower vertical marginal gap values than 4mm intracoronal cavity depth extension. Conclusions: All obtained marginal adaptation values lie within the clinically accepted ranges. Increasing intra-coronal cavity depth of endocrown preparation negatively affects marginal adaptation of lithium disilicate based endocrowns. Endocrown with shoulder finish line marginal configuration has superior marginal adaptation than those with butt joint marginal configuration.
A Dual Frequency RF-DC Rectifier Circuit with a Low Input Power for Radio Frequency Energy Harvesting

The energy-harvesting radio frequency (RF) can be an attractive alternative energy capable of replacing all or some of the board batteries. The RF waves are present in several high frequencies ([Formula: see text] GHz) and at low power (a few [Formula: see text]W). An energy-harvesting circuit designed must provide 1[Formula: see text]V voltage at minimum that is able to operate an actuator or a sensor. The RF-DC rectifier is the main component of an energy-harvesting circuit. This paper presents a new design RF-DC rectifier circuit using the MOSFET transistors, the capacitors and the inductors. Our proposed circuit is a combination of an Inductor–Capacitor–Inductor–Capacitor (LCLC) serie-parallel resonant tank (SPRT) and rectifier cascade using the Dynamic threshold Voltage Cancellation (DVC) and the technique of the Internal threshold Voltage Cancellation (IVC). Our proposed circuit operates in dual frequencies [Formula: see text][Formula: see text]GHz and [Formula: see text][Formula: see text]GHz with a low input power [Formula: see text][Formula: see text][Formula: see text]W ([Formula: see text][Formula: see text]dbm) and [Formula: see text][Formula: see text][Formula: see text]W ([Formula: see text][Formula: see text]dbm), respectively. This circuit gives a Power Conversion Efficiency (PCE) of 56.9% and an output voltage [Formula: see text][Formula: see text]V for the frequency 2.543[Formula: see text]GHz and a PCE of 62.6% and an output voltage [Formula: see text][Formula: see text]V for the frequency 4[Formula: see text]GHz. The pre-layout simulations were performed using the Advanced Design System (ADS) and the technology used is CMOS 0.18[Formula: see text][Formula: see text]m from TSMC. The simulations were performed on the proposed circuit composed by three stages.
Security architecture for network virtualization in cloud computing.

Network virtualization has been a quite active research area in the last years, aiming to tackle the increasing demand for high performance and secure communication in cloud infrastructures. In special, such research efforts have led to security solutions focused on improving isolation among multiple tenant of public clouds, an issue recognized as critical both by the academic community and by the technology Industry. More recently, the advent of Software-Defined Networks (SDN) and of Network Function Virtualization (NFV) introduced new concepts and techniques for addressing issues related to the isolation of network resources in multi-tenant clouds while improving network manageability and flexibility. Similarly, hardware technologies such as Single Root I/O Virtualization (SR-IOV) enable network isolation in the hardware level while improving performance in physical and virtual networks. Aiming to provide a cloud network environment that efficiently tackles multi-tenant isolation, we present three complementary strategies for addressing the isolation of resources in cloud networks. These strategies are then applied in the evaluation of existing network virtualization architectures, exposing the security gaps associated to current technologies, and paving the path for novel solutions. We then propose a security architecture that builds upon the strategies presented, as well as upon SDN, NFV and SR-IOV technologies, to implement secure cloud network domains. The theoretical and experimental analyses of the resulting architecture show a considerable reduction of the attack surface in tenant networks, with a small impact over tenants’ intra-domain and inter-domain communication performance.
Nurse perception of nursing handover at the University Clinical Hospital in Zagreb

Introduction. Nursing handover refers to communication occurring between two shifts of nurses with the specific purpose of handing over information about patients under the nurses’ care. Several styles of nursing handover exist, whereas in Croatia written handover is legally required. Aim. The aim of the study was to examine nurses’ perception of the nursing handover: whether nursing handover improves patient safety, whether the content of the handover influences the quality of nursing care and whether the handover is important for continuity of nursing care. The aim was also to determine how the nursing handover is performed, how long it takes and whether written instructions are necessary for the nursing handover. Methods. The study was conducted between 1 October 2017 and 30 October 2017. The study was conducted on the basis of a questionnaire made specifically for this purpose. The questionnaire consisted of 14 questions. The first part of the questionnaire referred to the participants’ demographic data: years of service, age, gender, education level, workplace; the second part of the questionnaire referred to nurses’ perception of the nursing handover. Results. The questionnaire was filled in by 295 nurses. Out of this number, 40 were male and 255 female nurses. The majority of participants finished secondary education and have been working between 11 and 20 years. In most cases, nursing handover is recorded in electronic written form and also at the patient’s bedside. Over 90% of participants feel that the handover contributes to improved patient safety and quality of care. Conclusion. Nursing handover is recorded in electronic written form, as well as at the patient’s bedside on all wards that participated in the study. This form of handover ensures better continuity of care, improves patient safety and reduces loss of vital information. The need to draw up written instructions for the nursing handover was determined.

A Longitudinal Analysis of Volunteerism Activities for Individuals Educated in Public and Private Schools

Previous studies offer evidence that U.S. public and private high schools differentially influence volunteerism in adolescence. However, these studies are typically cross-sectional and only consider whether the individual volunteered or not. We address patterns of volunteering from adolescence into adulthood and the kind of volunteering activity in which individuals engage. We also theorize that distinctive civic values within public and private schools together with their respective organizational ties to other civic organizations channel students into particular volunteering activities. Relying on a longitudinal, nationally representative sample of U.S. adolescents, we track volunteering from adolescence into young adulthood and identify the types of volunteering activities in which respondents engage. Results demonstrate that the likelihood of volunteering changes through the life course, and students from different schooling backgrounds systematically sort into specific volunteering activities as our theories predict.
