Optical Detection of Vapor Mixtures Using Structurally Colored Butterfly and Moth Wings
Authors: Piszter Gábor , Kertész Krisztián , Bálint Zsolt , Biró László Péter
Published: July 2019

Photonic nanoarchitectures in the wing scales of butterflies and moths are capable of fast and chemically selective vapor sensing due to changing color when volatile vapors are introduced to the surrounding atmosphere. This process is based on the capillary condensation of the vapors, which results in the conformal change of the chitin-air nanoarchitectures and leads to a vapor-specific optical response. Here, we investigated the optical responses of the wing scales of several butterfly and moth species when mixtures of different volatile vapors were applied to the surrounding atmosphere. We found that the optical responses for the different vapor mixtures fell between the optical responses of the two pure solvents in all the investigated specimens. The detailed evaluation, using principal component analysis, showed that the butterfly-wing-based sensor material is capable of differentiating between vapor mixtures as the structural color response was found to be characteristic for each of them.

Authors: Assuncao Arthur , Aquino Andre , Câmara de M. Santos Ricardo , Guimaraes Rodolfo , Oliveira Ricardo
Published: July 2019

This paper proposes the use of the Statistical Process Control (SPC), more specifically, the Exponentially Weighted Moving Average method, for the monitoring of drivers using approaches based on the vehicle and the driver’s behavior. Based on the SPC, we propose a method for the lane departure detection; a method for detecting sudden driver movements; and a method combined with computer vision to detect driver fatigue. All methods consider information from sensors scattered by the vehicle. The results showed the efficiency of the methods in the identification and detection of unwanted driver actions, such as sudden movements, lane departure, and driver fatigue. Lane departure detection obtained results of up to 76.92% (without constant speed) and 84.16% (speed maintained at ≈60). Furthermore, sudden movements detection obtained results of up to 91.66% (steering wheel) and 94.44% (brake). The driver fatigue has been detected in up to 94.46% situations.

Published: July 2019

In this paper, we focus on detection of speed changes from audio data, representing recordings of cars passing a microphone placed near the road. The goal of this work is to observe the behavior of drivers near control points, in order to check whether their driving is safe both when approaching the speed camera and after passing it. The audio data were recorded in controlled conditions, and they are publicly available for downloading. They represent one of three classes: car accelerating, decelerating, or maintaining constant speed. We used SVM, random forests, and artificial neural networks as classifiers, as well as the time series based approach. We also tested several approaches to audio data representation, namely: average values of basic audio features within the analyzed time segment, parametric description of the time evolution of these features, and parametric description of curves (lines) in the spectrogram. Additionally, the combinations of these representations were used in classification experiments. As a final step, we constructed an ensemble classifier, consisting of the best models. The proposed solution achieved an accuracy of almost 95%, without mistaking acceleration with deceleration, and very rare mistakes between stable speed and speed changes. The outcomes of this work can become a basis for campaigns aiming at improving traffic safety.
Time-Series-Based Leakage Detection Using Multiple Pressure Sensors in Water Distribution Systems
Authors: Shao Yu , Li Xin , Zhang Tuqiao , Chu Shipeng , Liu Xiaowei
Published: July 2019

Leak detection is nowadays an important task for water utilities as leakages in water distribution systems (WDS) increase economic costs significantly and create water resource shortages. Monitoring data such as pressure and flow rate of WDS fluctuate with time. Diagnosis based on time series monitoring data is thought to be more convincing than one-time point data. In this paper, a threshold selection method for the correlation coefficient based on time series data is proposed based on leak scenario falsification, to explore the advantages of data interpretation based on time series for leak detection. The approach utilizes temporal varying correlation between data from multiple pressure sensors, updates the threshold values over time, and scans multiple times for a scanning time window. The effect of scanning time window length on threshold selection is also tested. The performance of the proposed method is tested on a real, full-scale water distribution network using synthetic data, considering the uncertainty of demand and leak flow rates, sensor noise, and so forth. The case study shows that the scanning time window length of 3–6 achieves better performance; the potential of the method for leak detection performance improvement is confirmed, though affected by many factors such as modeling and measurement uncertainties.

Published: July 2019

The inevitable revolution of the Internet of Things (IoT) and its benefits can be witnessed everywhere. Two major issues related to IoT are the interoperability and the identification of trustworthy things. The proposed Context-Aware Trustworthy Social Web of Things System (CATSWoTS) addresses the interoperability issue by incorporating web technologies including Service Oriented Architecture where each thing plays the role of a service provider as well as a role of service consumer. The aspect of social web helps in getting recommendations from social relations. It was identified that the context dependency of trust along with Quality of Service (QoS) criteria, for identifying and recommending trustworthy Web of Things (WoT), require more attention. For this purpose, the parameters of context awareness and the constraints of QoS are considered. The research focuses on the idea of a user-centric system where the profiles of each thing (level of trustworthiness) are being maintained at a centralized level and at a distributed level as well. The CATSWoTS evaluates service providers based on the mentioned parameters and the constraints and then identifies a suitable service provider. For this, a rule-based collaborative filtering approach is used. The efficacy of CATSWoTS is evaluated with a specifically designed environment using a real QoS data set. The results showed that the proposed novel technique fills the gap present in the state of the art. It performed well by dynamically identifying and recommending trustworthy services as per the requirements of a service seeker.

Published: July 2019

Virtual-force algorithms (VFAs) have been widely studied for accurate node deployment in wireless-sensor-network (WSN) applications. Their main purpose is to achieve the maximum coverage area with the minimum number of sensor nodes in the target area. Recently, we reported a new VFA based on virtual spring force (VFA-SF) and discussed in detail the corresponding efficiency via statistical analysis. The optimized strategy by adding an external central force (VFA-SF-OPT) was presented, which effectively eliminates the coverage hole or twisted structure in the final network distribution. In this paper, the parameter effects on VFA-SF and the VFA-SF-OPT were further investigated: (1) Node velocity dramatically affects the convergence rate of the node-deployment process. (2) A suitable external central force improves equilibrium distance and reduces energy consumption. (3) The effects of VFA-SF and VFA-SF-OPT for different types of obstacles are discussed. Generally, by choosing suitable parameters, both VFA-SF and VFA-SF-OPT can effectively improve node deployment and energy consumption for the whole sensor network. The results give important insight in parameter selection and information fusion in the application of a large-scale WSN.
Sensor Systems for FRP Lightweight Structures: Automotive Features Based on Serial Sensor Products
Authors: Klein Linda
Published: July 2019

To achieve resource efficiency and an increased performance, as well as a higher safety and more features for vehicles, lightweight composites are a central sphere of activity for automotive innovations. This becomes particularly striking if the focus is not only a reduced vehicle weight but also an efficient overall concept. In addition to compatible material technologies and component design, new electronic solutions are of interest. A research contribution at the Robert Bosch Company deals with the direct integration of a current automotive acceleration sensor in fiber-reinforced polymer (FRP) parts. The sensor is part of the passive vehicle safety. Primarily, the principal application of the currently mounted sensor as an integrated part of the vehicle structure was proven. Sensor-integrated parts were evaluated on their sensing functionality as well as their structural performance. The present research is done to use the integrated sensor for a secondary feature. The study shows that the sensor can also be an indicator for the condition of its surrounding FRP structure. Hence, the sensor integration makes it possible to derive a secondary feature for automobiles by using the current sensor for future functionalized lightweight structures.
A Robust Transmission Scheduling Approach for Internet of Things Sensing Service with Energy Harvesting
Authors: Hao Jie , Chen Jing , Wang Ran , Zhuang Yi , Zhang Baoxian
Published: July 2019

Maximizing the utility under energy constraint is critical in an Internet of Things (IoT) sensing service, in which each sensor harvests energy from the ambient environment and uses it for sensing and transmitting the measurements to an application server. Such a sensor is required to maximize its utility under the harvested energy constraint, i.e., perform sensing and transmission at the highest rate allowed by the harvested energy constraint. Most existing works assumed a sophisticated model for harvested energy, but neglected the fact that the harvested energy is random in reality. Considering the randomness of the harvested energy, we focus on the transmission scheduling issue and present a robust transmission scheduling optimization approach that is able to provide robustness against randomness. We firstly formulate the transmission scheduling optimization problem subject to energy constraints with random harvested energy. We then introduce a flexible model to profile the harvested energy so that the constraints with random harvested energy are transformed into linear constraints. Finally, the transmission scheduling optimization problem can be solved traditionally. The experimental results demonstrate that the proposed approach is capable of providing a good trade-off between service flexibility and robustness.

Authors: Elasha Faris , Shanbr Suliman , Li Xiaochuan , Mba David
Published: July 2019

Deployment of large-scale wind turbines requires sophisticated operation and maintenance strategies to ensure the devices are safe, profitable and cost-effective. Prognostics aims to predict the remaining useful life (RUL) of physical systems based on condition measurements. Analyzing condition monitoring data, implementing diagnostic techniques and using machinery prognostic algorithms will bring about accurate estimation of the remaining life and possible failures that may occur. This paper proposes to combine two supervised machine learning techniques, namely, regression model and multilayer artificial neural network model, to predict the RUL of an operational wind turbine gearbox using vibration measurements. Root Mean Square (RMS), Kurtosis (KU) and Energy Index (EI) were analysed to define the bearing failure stages. The proposed methodology was evaluated through a case study involving vibration measurements of a high-speed shaft bearing used in a wind turbine gearbox.
A Review of the Capacitive MEMS for Seismology
Authors: D’Alessandro Antonino , Scudero Salvatore , Vitale Giovanni
Published: July 2019

MEMS (Micro Electro-Mechanical Systems) sensors enable a vast range of applications: among others, the use of MEMS accelerometers for seismology related applications has been emerging considerably in the last decade. In this paper, we provide a comprehensive review of the capacitive MEMS accelerometers: from the physical functioning principles, to the details of the technical precautions, and to the manufacturing procedures. We introduce the applications within seismology and earth sciences related disciplines, namely: earthquake observation and seismological studies, seismic surveying and imaging, structural health monitoring of buildings. Moreover, we describe how the use of the miniaturized technologies is revolutionizing these fields and we present some cutting edge applications that, in the very last years, are taking advantage from the use of MEMS sensors, such as rotational seismology and gravity measurements. In a ten-year outlook, the capability of MEMS sensors will certainly improve through the optimization of existing technologies, the development of new materials, and the implementation of innovative production processes. In particular, the next generation of MEMS seismometers could be capable of reaching a noise floor under the lower seismic noise (few tenths of ng/ Hz ) and expanding the bandwidth towards lower frequencies (∼0.01 Hz).

Authors: Wójciak Karolina M. , Stasiak Dariusz M. , Kęska Paulina
Published: July 2019

This study focuses on collecting actual data on the workable possibility of reducing the technological use of nitrites in beef products according to the present trends in nutrition, especially in terms of European Union (EU) food law. Measurements of safety by technological (pH value, water activity, N-nitrosamine), microbiological, oxidative stability (thiobarbituric acid reactive substances, oxidation-reduction potential), and color parameter (CIE L*a*b*, total heme pigment and heme iron) methods were taken after production and storage. The roasted beef with a reduced inclusion level of sodium nitrite (75 mg/kg and below) was more vulnerable to lipid oxidation. The quantities of primary lipid oxidation products were related to the sodium nitrite inclusion level (50–150 mg/kg). Clostridium spp., Staphylococcus aureus, and Listeria monocytogenes were not detected in any of the samples tested during all the experiments. The total count of Enterobacteriaceae increased with the decrease in sodium nitrite content, from log 2.75 cfu/g at the highest to log 6.03 cfu/g at the smallest addition of nitrite. The obtained results revealed that the addition of 100 mg/kg of sodium nitrite would be adequate for minced roasted beef, without significant unexpected effects on color, oxidative stability, and microbiological safety compared with the control (150 mg/kg).
How Will Changes toward Pro-Environmental Behavior Play in Customers’ Perceived Value of Environmental Concerns at Coffee Shops?
Authors: Kim Taeuk , Yun Sunmi
Published: July 2019

Our theoretical framework was designed to explain customers’ decision-making process for (adopting/using?) environmentally responsible products in an eco-friendly coffee shop. We employed theory of planned behavior (TPB) and value-attitude-belief (VAB) to test their parallel mediating effect on attitudes toward environmental behavior (ATEB), perceived marketplace influence (PMI), and overall image (OI) as well as the moderating effect of switching cost (SC) on pro-environmental behavioral intentions. Data were collected through a survey of 527 customers who frequently visited a coffee shop in Korea, and structural equation modeling (SEM) was used to test the research hypotheses. The findings generally supported the hypothesized associations of the study variables within our proposed theoretical framework (ATEB, PMI, and OI of the parallel mediating effect on pro-environmental behavioral intentions) and confirmed SC’s moderating effect. In addition, the study’s results have important 1) theoretical and 2) practical implications for the environment. 1) This study confirmed the relationship between mediating variables on PCBI and the parallel mediating effect on PCBI as demonstrated in previous studies. 2) Furthermore, these findings might lead coffee shops to voluntarily put an end to the use of disposable products such as plastic cups or straws, which carry great environmental risk.

Published: July 2019

The origin of clays minerals (beidellite, illite, attapulgite, sepiolite), has been determined by a mineralogical and geochimical study. The detrital material (of pedological origine) was essentially constitued by ferruginous beidellites. In the environment of deposit, these beidellites followed two evolutions :

— aggradation into illite, by fixation of potassium taken off oceanic water ;

— transformation into attapulgite by incorporation of magnesium into the silicate layer, in a more confined, continental environment. Sepiolite neformed when environment was the most confined.

Flux et déplacements dans le Caucase
Authors: Thorez Pierre
Published: July 2019

The Caucasus is a range of high mountains between the Black Sea and the Caspian Sea. Its length is about 1000 km and its width ranges from 100 to 250 km. Indigenous mountain-dwellers who practised transhumance and did a lot of trade with the lowlands covered by steppe in the north and by crops in the south, crossed this natural obstacle. The conquest by the Russians isolated the mountain-dwellers and despite the construction of few new roads, flows, railway mainly, bypassed the mountain. Most of the Tcherkess who dwelt in the Western Caucasus left the country. The integration of Transcaucasia into the Soviet system stimulated exchanges through the Caucasus and new roads were built. Several nationalities, including the Chechens were oppressed during the Stalinist era which temporary modified the settlement. The collapse of the USSR had more important consequences. Due to the military conflicts and the now severely controlled boundaries the transhumance disappeared and the traffic across the mountain decreased. The new transportation policies consist in developping relations between the Black Sea and Central Asia (TRACECA and KTK through Russia). Actually, technical and political environments constrain more than natural environment.

After 50 years of nationhood, about 60 million Pakistani citizens still
live in absolute poverty which is a condition so debasing that it robs the
poor of the very potential of their genes. Illiteracy, malnutrition, high
maternal, child and infant mortality afflict more than 50% of Pakistan’s
population of 144 million. Due to mismanagement of its human and natural
resources Pakistan is in a vicious cycle of economic dependence (Figures 2 &
3) with high indebtedness, low growth rates of exports and GDP and a
decaying education system. During the last two decades Pakistan has
engaged in firefighting through external debt re-schedulings and increasing
its dependence on the Bretton Woods institutions (World Bank,
International Monetary Fund) and their richer shareholders. As a result the
important development needs of the nation’s human capital have been
grossly neglected. It has failed to develop its human capital, particularly its
domestic scientific and engineering communities and thus is not ready to
meet the growth challenges of the 21st century. It is postulated that Pakistan
must, on a crash basis, develop a domestic scientific and technology (S&T)
community and create a scientific infrastructure if it seeks to become
economically and politically self-reliant.

Potential effectiveness of sleep hygiene and relaxation Benson in improving the quality of sleep in patients with heart failure: Literature review
Authors: Kamal Musaddad -
Published: July 2019

Abstract

Heart failure has now become a global cardiovascular problem with high mortality and disability. Sleep disturbance is a common problem in heart failure patients. Sleep disorders that occur in patients with heart failure will cause increased levels of urine catecholamine, plasma leptin, and inflammatory markers. These changes are related to the development of hypertension, activation of the sympathetic nervous system, and blunting of chemoreflex, which will increase the heart burden and ultimately lead to a poor prognosis. Sleep disorders in heart failure patients can be treated with psychological interventions and behaviors including sleep hygiene and Benson relaxation. Nurses, as one of the health professionals, have an important role in this matter. This is because the scope of nursing is meeting basic human needs, namely sleep. Through intervention in sleep hygiene and relaxation, Benson is expected to be able to improve the patient's sleep quality.

Nowadays, people’s mobility is fast and variable, needing better and more environmentally friendly transportation, without neglecting the socio-economic aspect. These are the reasons to develop better and more environmentally related transportation facilities. By understanding air pollution mechanisms, and kinds of particles and pollutants from vehicles, we will appreciate and pay more attention to our environment, especially in urban areas. Collaboration among health and government related departments has to be improved to regulate the use of inner city vehicles, so that it can decrease lung problems. Key words: air pollution, transportation, dust particles, urban environment.     Abstrak: Bertambahnya jumlah kendaraan bermotor seiring dengan bertambahnya polusi udara, dan menimbulkan masalah global, yang berdampak negatif antara lain masalah kesehatan paru.

Abstract: Body temperature is defined as one of the vital signs that indicates the health status of a person. Compared with other primates, man has a greater ability to tolerate hot temperatures due to his many sweat glands, and that his skin is covered mostly by fine hair. In our bodies, heat energy is produced by muscles (mostly), sweat glands, fats, bones, connective tissues, and nerves. Heat energy is distributed to the whole body by blood circulation, but the temperatures are not the same in all parts of the body. There is a difference (around 40C) between core and surface body temperatures. The thermoregulator system has to obtain two suitable gradients: 1) between core and surface body temperatures, and 2) between surface and ambient temperatures. The gradient between core and surface body temperatures is the most important one to maintain optimum body function. Understanding from physics the aspect of body temperature and its influence on homeostatis mechanism, gives some valuable contribution to applied clinical sciences. Key words: core temperature, skin temperature, energy.     Abstrak: Suhu tubuh didefinisikan sebagai salah satu tanda vital yang menggambarkan status kesehatan seseorang. Dibandingkan dengan primata lainnya, manusia mempunyai kemampuan yang lebih besar untuk mentolerer suhu tinggi oleh karena banyaknya kelenjar keringat, dan kulitnya hanya ditumbuhi oleh rambut halus. Di dalam tubuh energi panas dihasilkan oleh jaringan aktif terutama dalam otot, kemudian juga dalam alat keringat, lemak, tulang, jaringan ikat, serta saraf. Energi panas yang dihasilkan didistribusikan ke seluruh tubuh melalui sirkulasi darah, namun suhu bagian-bagian tubuh tidak merata. Terdapat perbedaan yang cukup besar (sekitar 4°C) antara suhu inti dan suhu permukaan tubuh.6,7 Sistem termo-regulator tubuh harus dapat mencapai dua gradien suhu yang sesuai, yaitu: 1) antara suhu inti dengan suhu per-mukaan, 2) antara suhu permukaan dengan suhu lingkungan. Dari keduanya, gradien suhu inti dengan suhu permukaan adalah yang terpenting untuk kelangsungan fungsi tubuh yang optimal. Pemahaman tentang besaran suhu dan pengaruhnya terhadap mekanisme homeostatis tubuh melalui pendekatan hukum-hukum fisika setidaknya memberi kontribusi yang berarti pada bidang ilmu klinis terapan. Kata kunci: suhu inti, suhu kulit, energi.
