Practical Endurance Estimation for Minimizing Energy Consumption of Multirotor Unmanned Aerial Vehicles

The practically applicable endurance estimation method for multirotor unmanned aerial vehicles (UAVs) using a battery as a power source is proposed. The method considers both hovering and steady-level flights. The endurance, thrust, efficiency, and battery discharge are determined with generally available data from the manufacturer. The effects of the drag coefficient related to vehicle shape and payload weight are examined at various forward flight speeds. As the drag coefficient increases, the optimum speed at the minimum required power and the maximum endurance are reduced. However, the payload weight causes an opposite effect, and the optimal flying speed increases with an increase in the payload weight. For more practical applications for common users, the value of S × Cd is determined from a preliminary flight test. Given this value, the endurance is numerically estimated and validated with the measured flight time. The proposed method can successfully estimate the flight time with an average error of 2.3%. This method would be useful for designers who plan various missions and select UAVs.
Exotic Massive 3 D Gravity

The linearized equations of “New Massive Gravity” propagate a parity doublet of massive spin-2 modes in 3D Minkowski spacetime, but a different non-linear extension is made possible by “third-way” consistency. There is a “Chern-Simons-like” action, as for other 3D massive gravity models, but the new theory is “exotic”: its action is parity odd. This “Exotic Massive Gravity” is the next-to-simplest case in an infinite sequence of third-way consistent 3D gravity theories, the simplest being the “Minimal Massive Gravity” alternative to “Topologically Massive Gravity”.

EBITDA multiply is a strong determinant of stock returns and stocks with low EV/EBITDA multiples have higher returns for the next period.
Demand-driven logistics from a packaging perspective

During the last decade there has been a shift of focus from supply management towards demand management in logistics literature and practice. This article sets out to investigate what impact such a shift has on logistics, especially from a packaging perspective. An extensive literature review has been conducted, focusing on the top three journals in logistics as well as in operations management (JBL, IJPDLM, IJLM, JOM, IJOPM and POM). The results of the literature review show that there has not been much focus on the impact of the increased demand focus on operational logistics. In particular, the results indicate a lack of attention to packaging effects due to the increased demand focus. Two interview studies have been conducted in the telecommunication industry and in the automotive industry. Both studies demonstrate that there are packaging-related issues which, based on a shift in focus from supply to demand, have changed the handling and requirements of packages and logistics as a whole. Implications for research and management are provided at the end of the paper. (Less)
WEBLOG FOR TEACHERS AND STUDENTS

Educators are always looking for interesting and innovative ways in which to improve the communications skills of their students and in communicating with their students. This is even more important when the students are studying online. Weblogs, originally a simple web browser based system for updating websites, have developed into powerful web based content management systems, capable of acting as a platform for learning that can accelerate the development of expertise learner behaviour. There is a trend to utilize the benefits of the e-learning as a mechanism to improve learning performance of campus-based students. Whilst traditional methods, such as face-to-face lectures, tutorials, and mentoring, remain dominant in the educational sector, universities are investing heavily in learning technologies, to facilitate improvements with respect to the quality of learning. This study explores into the role of weblogs in supporting teachers during their teaching practice and the key factors determining their engagement with weblogs. Underlying our study is an integrative approach that puts weblogs alongside with other popular media in use. An online community was intentionally built with weblogs to facilitate reflection and social interaction among dispersed teachers. In parallel, multiple channels of communication were employed for peer interaction of students. Weblogs were perceived as valuable in relieving isolation, documenting their experience, and expressing their personal feelings. This study sustains our conviction that the integrative approach is vital to have a comprehensive picture of interaction among a community. Our study deepens the insights into the distinct benefit of weblogs as educational media and informs the future development of an online community with weblogs. Weblogs provide a chance for students to experience writing in a public space where their work can have real value both for their classmates and for a wider community. This prepares students for a networked world where communication is essential and often social and where writing can have consequences.
Effectiveness of interventions to promote physical activity in overweight adults in the health care setting : a systematic review

Nuojua Sohvi Katariina, 2017. Effectiveness of Interventions to Promote Physical Activity in Overweight Adults in the Health Care Setting: A Systematic Review. Department of Sport Sciences. University of Jyväskylä. 74 p. Overweight and obese individuals are at a significant risk for developing cardiovascular disease and other health concerns. Increasing physical activity (PA) in this population is associated with weight loss and positive health outcomes. One way of promoting PA is through interventions in the health care setting. Research is needed to identify the most effective ways of motivating overweight individuals to increase their PA behaviour and to maintain these changes. This systematic review seeks to synthesise current evidence on the effectiveness of behavioural interventions aimed at increasing PA in the overweight and obese population in the health care setting. Literature searches were performed to locate RCT behavioural interventions with follow-up data, targeting PA in healthy overweight and obese adults (BMI>25) in health care settings. Two rounds of literature search were done in electronic databases for MEDLINE, EMBASE, CINAHL, CCRCT, and PsycINFO in spring 2015 and 2017. 11 primary studies were identified. The included studies were evaluated for risk of bias. Data extracted included participant characteristics, results on PA, behaviour change techniques (BCTs) and theoretical frameworks used, and properties of intervention delivery. The BCTs used were coded by two independent assessors using the Behaviour Change Taxonomy version 1. Qualitative synthesis was determined as the most suitable method for reporting the summative data. Most studies were rated as being at low risk of bias. Majority of the studies reported significant time-effects that were rarely maintained at follow-up. Significant increases in PA that favoured the experimental condition were identified in three studies. No superiority of individual BCTs was identified, although self-monitoring was frequently used by successful studies. There was no indication of any intervention delivery properties being associated with intervention success. The limitations of the review include heterogeneity and risk of bias within the study pool, as well as lack of interrater communication. The qualitative synthesis cannot provide enough information for a conclusion to be made yet on the effectiveness of specific BCTs in motivating the overweight and obese population to increase their PA behaviour. The only recommendation for guiding practice is that self-monitoring may be an effective technique for increasing PA in the health care environment, albeit this recommendation is based on weak evidence. Future RCTs should ensure high methodological quality and adequate reporting of BCTs used so that they can contribute to prospective systematic reviews and provide stronger evidence for guiding practice in the health care setting.
Severe disease of melon in North West Frontier Province is associated with simultaneous infection of two RNA viruses

During a search for cucurbit viruses in NWFP, a very severe disease of melon (Cucumis melo L.) characterized by leaf curling, chlorotic spots, vein clearing, mosaic, leaf distortion and enations on the upper leaf surface was identified in commercial fields in Mardan District, NWFP. Symptomatic plants were screened for the presence of Zucchini yellow mosaic virus (ZYMV) and Cucumber mosaic virus (CMV) by double antibody sandwich enzyme-linked immounosorbent assay (DAS-ELISA). Plants were also tested for the presence of begomoviruses by polymerase chain reaction and Southern hybridization using general probes. No sample was found positive for begomoviruses. The presence of CMV and ZYMV was confirmed by DAS-ELISA. Our results show that the severe disease found on melon in Mardan district is caused by multiple infections of two viruses and the severity result from synergism between two viruses.
Using the Maturity Method in Predicting the Compressive Strength of Vinyl Ester Polymer Concrete at an Early Age

The compressive strength of vinyl ester polymer concrete is predicted using the maturity method. The compressive strength rapidly increased until the curing age of 24 hrs and thereafter slowly increased until the curing age of 72 hrs. As the MMA content increased, the compressive strength decreased. Furthermore, as the curing temperature decreased, compressive strength decreased. For vinyl ester polymer concrete, datum temperature, ranging from −22.5 to −24.6°C, decreased as the MMA content increased. The maturity index equation for cement concrete cannot be applied to polymer concrete and the maturity of vinyl ester polymer concrete can only be estimated through control of the time interval . Thus, this study introduced a suitable scaled-down factor ( ) for the determination of polymer concrete’s maturity, and a factor of 0.3 was the most suitable. Also, the DR-HILL compressive strength prediction model was determined as applicable to vinyl ester polymer concrete among the dose-response models. For the parameters of the prediction model, applying the parameters by combining all data obtained from the three different amounts of MMA content was deemed acceptable. The study results could be useful for the quality control of vinyl ester polymer concrete and nondestructive prediction of early age strength.
Analysing the Economic Impact of the Olympics Using Stock Market Indices of Host Countries

Hallmark events are defined as those which promote a host city as an international tourism destination (Hall, 1992). They are on a scale that can produce a high performance in tourism, media coverage and economic impact for the host community or destination (Getz, 1997). Moreover, most hallmark events have substantial government commitment. Mega events include religious, cultural, commercial, political and/or sports events. According to Hall (1992), sporting events are the most notable model of hallmark events. The Summer and Winter Olympic Games are identified as mega sports events. Mega sporting events are the most notable model of hallmark events and they have the characteristics of a festival. Traditional sports events like the Olympics always combine ceremonies and festivals (Getz, 1997). A mega event has two main characteristics: internal aspects and external aspects. The internal aspect is mainly its scale while the external aspect is mostly its attractiveness to tourism and the media, and its economic impact on the host city. (Malfas, et al., 2004). Although mega events have a limited duration, they have a huge impact on the host country in terms of tourist volumes, visitor expenditure, heightened awareness and a positive image of the city. There are also related infrastructural and organizational developments, which increase the destination’s competence and attractiveness (Fayos-Sola, 1997). As the Olympics are mega event and arguably the most prestigious of all sporting events, the Games are held on a scale that can produce a high performance in tourism, media coverage and economic impact for the host community or destination. The purpose of this paper is to examine the economic impact of the Summer Olympic Games on the host cities using the stock market approach. There are very few studies which examine stock market reactions to mega sporting events selection announcement. Given the benefits of hosting the Olympic Games and the fierce competition which accompanies the selection of host Olympics cities, we would expect a positive (negative) market reaction on the stock exchange of the country which wins (loses) the bid to host the Games. Most of the cities which have hosted the Olympics are already tourist destinations. We will compare the stock market performance of countries which hosted the five Summer Olympic Games from 1988 to 2004. The host countries vary from the large economies of the USA, Japan and France to the smaller economies like South Korea (in the 1980s) and Greece. Hence, the economic impact of the Olympics varies among host cities, depending on the economic scale of the host country in terms of their Gross Domestic Product.
SEVA: A non-linear mathematical framework for climate change vulnerability assessment

Assessing vulnerability to climate change allows policymakers to prioritize policy interventions and better allocate resources. Climate Change Vulnerability Assessment (CCVA) can play an important role in developing long-term environmental and infrastructure plans. Typically, a CCVA exercise combines knowledge from multiple disciplines (e.g., climate science, public health, social science, infrastructure systems, economics) in order to build models of the vulnerability to a climate-related stress of a valued attribute (e.g., health, prosperity, security) of a socio ecological system (SES) (e.g., local government area, councils, counties). In indicator-based vulnerability assessments (IBVA), indicators are adopted as proxy measures of processes generating vulnerability. However, some of the widely recognized challenges of IBVA have been the absence of a mathematically robust framework that can combine information from different knowledge domains, while taking into account the partial compensation of loss/gain between indicators, non- linearities, and tipping points. In one of our previous papers we showed that even though their goals are fundamentally different, Multi-Criteria Decision Analysis (MCDA) and IBVA have the same structural features. Hence, we proposed an aggregation framework for IBVA using insights from the older and more mature field of MCDA (El-Zein and Tonmoy, 2013a) . The goal of this paper is to extend this framework in order to define and deal with non-linear relationships and threshold effects commonly occurring in IBVA. We first identify different sources of non-linearity present in the context of IBVA. We distinguish between a fundamental nonlinearity (dependence of vulnerability on magnitude of stress), a deductive nonlinearity (where a deductive or mechanistic model is required to identify the relationship between a set of indicators and vulnerability) and an intuitive nonlinearity (where the same relationship is characterized as non-linear through inductive arguments by stakeholders and/or experts). Second, we build a new framework called the Sydney Environmental Vulnerability Assessment (SEVA) by introducing harm as a concept that replaces or mediates the relationship between the indicator and the vulnerability it represents. Harm can be conceived of as a more concrete, less abstract form of vulnerability that is more amenable to quantification. A harm criterion then, like an indicator, acts as a proxy for a process generating vulnerability. However, a harm criterion allows us to achieve two key objectives: a) to relax the conditions concerning linearity, and b) to separate deductive and intuitive nonlinearities in order to better deal with both of them. SEVA conducts
Institutional Change and Economic Transition: Market-Enhancing Governance, Chinese-Style

This study introduces a coherent comparative concept of governance, applies it to China, and elaborates to what extent the Chinese institutional matrix exhibits characteristics of a market-enhancing governance structure (MEGS). It is argued that a subtle interplay of political and economic institutions created a stable and viable politico-institutional foundation which made China's unorthodox transition strategy politically feasible and economically effective. The paper concludes with an assessment of the quality of the overall Chinese governance structure and its expected implications for the future transition process.
Interactions of caligid ectoparasites and juvenile gadids on Georges Bank

The role of the ectoparasite Caligus sp. (Copepoda: Caligidae) in the northeast Georges Bank cod-haddock ecosystem was examined. Vertical distribution of free-living Caligus elongatus adults and host-parasite relationships of juvenile CaLigus sp. and juvenile gadids are described at 2 locations with contrasting oceanographc properties, one thermally stratified and the other well-mixed. Cod Gadus morhua had both greater prevalence and number of Caligus sp. ectoparasites than did haddock Melanogran~mus aeylefinus at both locations. Preferred sites of attachment on the host also differed. While no direct evidence of reduced fish condition as a function of parasite infestation was found, circumstantial evidence is offered in support of the hypothesis that Caligus sp. ectoparasitism is a source of mortality for young haddock. Free-living C. elongatus were demonstrated to be a significant component of fishes' diet, particularly for cod at the stratified site where zooplankton were less abundant.
Indirect NFC-Login on a Non-NFC Device using an NFC-Smartphone

Smartcard based authentication on web services stays a niche application because of the lack of smartcard readers on the vast majority of internet devices. In this paper we discuss a method that uses an NFC-enabled Smartphone in order to login via NFC-enabled smartcard on basically any internet device. We explain the details of this method and analyze its security, deployability, and usability aspects.
Driver intention modelling for partly automated vehicles- The benefit and necessity of a driver and situation adaptive approach

Partly automated vehicles like shown in the HAVEit project [6] can be seen as a bridge towards self-driving vehicles as known from Google [5] or BMW [3]. Partly automated vehicles still take over control in lateral and longitudinal direction but additionally involve the driver. This is an advantage compared to fully automated vehicles in case the automation fails and the driver has to take over. As the BASt pointed out in its last report [1] this is a main reason while partly automated vehicles would get a licence in Germany in contrast to fully automated vehicles. Since the human is embedded in the control loop cooperation is a cornerstone of partly automated vehicles. Cooperation works if both the human and the machine follow same intentions. A discrepancy in their intentions leads to conflicts in the human machine interaction as described in [2]. Clearly, conflicts are decreasing the acceptance and the stability of the system. Therefore it is essential firstly to detect conflicts and secondly to develop strategies to solve them. This is the part where driver intention modelling becomes mandatory. Knowing driver’s intention means knowing the potential for a conflict. Moreover it allows to adapt automation behaviour to the driver and thus to reduce the conflict potential. Driver intention modelling is therefore closely linked to adaptive systems.
Self-regulated learning in higher education: strategies adopted by computer programming students when supported by the SimProgramming approach

The goal of the SimProgramming approach is to help students overcome their learning difficulties in the transition from entry-level to advanced computer programming, developing an appropriate set of learning strategies. We implemented it at the University of Trás-os-Montes e Alto Douro (Portugal), in two courses (PM3 and PM4) of the bachelor programmes in Informatics Engineering and ICT. We conducted semi-structured interviews with students (n=38) at the end of the courses, to identify the students’ strategies for self-regulation of learning in the assignment. We found that students changed some of their strategies from one course edition to the following one and that changes are related to the SimProgramming approach. We believe that changes to the educational approach were appropriate to support the assignment goals. We recommend applying the SimProgramming approach in other educational contexts, to improve educational practices by including techniques to help students in their learning.

Use and Attitude towards Learning Management Systems (LMS) in Saudi Arabian Universities

Background:Learning Management Systems have been adopted in various institutions due to their numerous functionalities to improve pedagogy. As a result faculty members are urged to utilise them for enhancing teaching and learning practices.Material and methods:Underpinning this study was a questionnaire distribution with a sample size of 222 faculty members in six universities. Cross-tabulation in a bar graph form and chi-square test were conducted to verify the observed differences between variables.Results:The findings revealed that older generation of faculty members tended to use LMS for many of their teaching activities than the younger counterparts. LMS was not actively used for most teaching purposes. Statistically significant association existed between resources organisations via LMS and restriction level (χ2 (12) = 24.890, p = 0.015). Attitude of those members who do not use LMS differ from those who use LMS for some and most teaching activities in terms of online examinations and social media.Conclusions:Attitude on LMS usage for pedagogical enrichment were based on individual faculty member's evaluation of the LMS.
