Published: October 2019

Modern men have health problems caused by lack of exercise than in the past. But most modern people do not know what to do exercise. Mobile systems for fitness to solve this problem have been developed. In this paper, by analyzing the user's BMI (Body Mass Index) Index and BMR (Basal Metabolic Rate) value, the data is made available. The processed data is provided to the user which proposes the right exercise and the appropriate level of exercise intensity, for exercise machines. This is different from detecting the movement, like the existing system, and a fitness value showing the calorie consumption caused. Thus the user is considered to be able to efficiently proceed to a movement based on the provided data.

An effective video surveillance system is highly essential in order to ensure constructing better form of video analytics. Existing review of literatures pertaining to video analytics are found to directly implement algorithms on the top of the video file without much emphasis on following problems i.e. i) dynamic orientation of subject, ii)poor illumination condition, iii) identification and classification of subjects, and iv) faster response time. Therefore, the proposed system implements an analytical concept that uses depth-image of the video feed along with the original colored video feed to apply an algorithm for extracting significant information about the motion blob of the dynamic subjects. Implemented in MATLAB, the study outcome shows that it is capable of addressing all the above mentioned problems associated with existing research trends on video analytics by using a very simple and non-iterative process of implementation.

Published: October 2019

This research work focused on transmission channel characterization of Free-Space-Optical (FSO) communications technology for deploying in the developing country like Bangladesh. To meet the tremendous amount of data traffic, mobile operators and ISPs need better solution than the existing RF and fiber optic communications. Moreover, Bangladesh is entering in the era of satellite communications by launching its own satellite.  So, Bangladesh needs such communication technology that provides higher channel bandwidth, sophisticated transmission security and can cope channel dispersion. FSO is a good candidate that can meet all these features. The transmission channel characterization plays a significant role in optimizing the performance of FSO link.  In this work, the channel characterization of FSO technology from the weather perspective of Bangladesh has been investigated thoroughly. The obtained results show that the atmospheric scattering effect does not hamper the short range FSO link performance, whereas, the atmospheric turbulence effect is not favorable to deploy FSO technology with reasonable quality signal unless it is optimized properly using antenna aperture averaging technique.

Authors: Hocine Sekhane , Djamel Labed
Published: October 2019

The fast increase of loads around the world has made electrical networks more and more complex and difficult to operate close to its capacities. This is has led to many problems such as voltage collapse and energy losses. Therefore, flexible alternating current transmission systems (FACTS) are considred as a best solution for solving these problems. Unified Power Flow Controller UPFC is one of the most important and powerful FACTS devices due to its ability to increase the transmission capacity of the power system and reduce the total line losses. The problem of optimizing its number, location and size has become an important requirement for best advantages of this device. In this paper, a proposed relationship to identify the maximum number of FACTS devices that can be installed for a given power network is introduced in the search process code to determine the optimal number, optimal placement and size of UPFC device to enhance voltages profile and reduce overall system losses in the standard IEEE 14 bus test system using genetic algorithm (GA). The obtained results show clearly that all control parameters of UPFCs in each case are within their limits, and whenever the number of UPFCs installed increases, both voltage deviation and total losses well decreases. They also show that the application of the proposed relationship in the search process code facilitates greatly the search for optimal number, optimal placement and size of UPFC devices and reduces the calculation time. On the other hand, the obtained results has been scientifically justified and compared with other works reported in the literature.

Authors: Sharma Shivani , Sebastian Shoney
Published: October 2019

With an increase in population, there is an increase in the number of accidents that happen every minute. These road accidents are unpredictable. There are situations where most of the accidents could not be reported properly to nearby ambulances on time. In most of the cases, there is the unavailability of emergency services which lack in providing the first aid and timely service which can lead to loss of life by some minutes. Hence, there is a need to develop a system that caters to all these problems and can effectively function to overcome the delay time caused by the medical vehicles. The purpose of this paper is to introduce a framework using IoT, which helps in detecting car accidents and notifying them immediately. This can be achieved by integrating smart sensors with a microcontroller within the car that can trigger at the time of an accident. The other modules like GPS and GSM are integrated with the system to obtain the location coordinates of the accidents and sending it to registered numbers and nearby ambulance to notify them about the accident to obtain immediate help at the location.

Published: October 2019

Microwave imaging is an emerging technology in the medical application which have similar functions as X-ray, Magnetic Resonance Imaging (MRI), and Computed Tomography scan (CT scan). In designing a microwave imaging system for medical application, it can use a monostatic radar approach by transmitting a Gaussian pulse (with an ultra-wideband (UWB) frequency). In this system, eight antennas are required with the support of RF switches. Thus, it is important to get the best performance of UWB RF switch in this application. Therefore, this paper presents the performance analysis of four different RF switch topologies (Design 1, 2, 3 and 4) using discrete PIN diode in SC-79 package. The design was based on single pole double throw (SPDT) switch. As result, Design 2 is the best topology after considering the tradeoff between isolation and return loss performances. Based on the three cascaded SPDT switches of Design 2, the insertion loss was less than -2 dB and return loss was more than -10 dB. Meanwhile, the isolation bandwidth (at the minimum isolation of -20 dB) was from 0.5 to 3.7 GHz (with 3.2 GHz bandwidth), hence, it could be used in the UWB frequency for medical application of microwave imaging.

Authors: G Saranya
Published: October 2019

Data Hiding has a huge range of applications in the medical field for transmission. It is helpful in securing the documentation of the patients from the violator with good storage space. The medical images of different modalities like CT, MRI, and PET with the digitized clinical information can be sent to the doctors across the world for the treatment. Due to the bandwidth and storage constraints, medical images along with the clinical information must be compressed before transmission and storage. This paper gives a technique for hiding the digitized clinical information along with the DICOM images in Complex Contourlet Transform (CCT) Domain. It also analyses the compression method by using an Entropy Encoder method. Hence, this work suggests that the data hiding method based on Complex Contourlet Transform (CCT) is efficient and also it has a high hiding capacity. The improved value of Compression Ratio (CR), Space Saving (SS), Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR) shows that the new method satisfies the properties of the data hiding method.

Published: October 2019

In order to reduce costs while maintaining superior performance, this paper presents a new control methodology of a three-phase grid connected photovoltaic system without using the intermediary DC/DC converter. Based on the synchronized nonlinear model of the whole photovoltaic system, two controllers have been proposed for the three-phase inverter in order to ensure the operation of the PV system at the maximum power point with unity power factor and minimum grid disturbance. Grid synchronization has been ensured by a three-phase 2nd order PLL (Phase-Locked Loop). The stability of each controller is demonstrated by means of Lyapunov analysis and evaluated under changing atmospheric conditions using the Matlab/Simulink environment, the simulation results clearly demonstrate the performance provided by each controller.

Authors: J. A. Nair Susmita , Nair T. R. Gopalakrishnan
Published: October 2019

In virtualized servers, with live migration technique pages are copied from one physical machine to another while the virtual machine (VM) is running. The dynamic migration of virtual machines encumbers the data center which in turn reduces the performance of applications running on that particular physical machine. A considerable number of studies have been carried out in the area of performance evaluation during live VM migration.  However, all the aspects related to the migration process have not been examined for the performance assessment. In this paper, we propose a novel approach to evaluate the performance during migration process in different types of coupled machine environment. It is presented here that the state of art VM migration technology requires further improvement in realizing effective migration by monitoring comprehensive performance value. We introduced the parameter, θ, to compare performance value which can be used for controlling and halting unsuccessful migration and save significant amount of time in migration operation.  Our model is capable of analyzing real time scenario of cloud performance assessment targeting VM migration strategies. It also offers the possibility of further expanding to universal models for analyzing the performance variations that occurs as a result of VM migration.

Published: October 2019

Flooding is one of the most devastating natural disasters in the world. It occurs when water from heavy rains exceeds the capacity of the river banks into which it runs. Some roads are also being affected when this natural phenomenon happens which lead to closure of roads. This closure, however, are often dissiminated late to the people that are passing through the closed roads. For this purpose, a Road Flood Warning System with Information Dissemination via Social Media has been developed to provide timely flood alert information to the public. The system determines the depth of the water through an ultrasonic sensor and disseminates the data gathered to the Internet through the use of social media sites specifically Twitter and Facebook. Moreover, the system has a LED matrix and light emitting diode to display whether the roads are passable during the occurrence of floods. The test results on the performance of ultrasonic sensor showed an accuracy of 98.69% while dissemination of information was 90% successful.

Published: October 2019

Wireless Sensor Network (WSN) is a distributed wireless connection that consists many wireless sensor devices. It is used to get information from the surrounding activities or the environment and send the details to the user for future work. Due to its advantages, WSN has been widely used to help people to collect, monitor and analyse data. However, the biggest limitation of WSN is about the network lifetime. Usually WSN has a small energy capacity for operation, and after the energy was used up below the threshold value, it will then be declared as a dead node. When this happens, the sensor node cannot receive and send the data until the energy is renewed. To reduce WSN energy consumption, the process of selecting a path to the destination is very important. Currently, the data transmission from sensor nodes to the cluster head uses a single hop which consumes more energy; thus, in this paper the enhancement of previous algorithm, which is MAP, the data transmission will use several paths to reach the cluster head. The best path uses a small amount of energy and will take a short time for packet delivery. The element of Shortest Path First (SPF) Algorithm that is used in a routing protocol will be implemented. It will determine the path based on a cost, in which the decision will be made depending on the lowest cost between several connected paths. By using the MATLAB simulation tool, the performance of SPF algorithm and conventional method will be evaluated. The expected result of SPF implementation will increase the energy consumption in order to prolong the network lifetime for WSN.

Published: October 2019

The rapid development of Internet along with the wide use of social media applications produce huge volume of unstructured data in short text form such as tweets, text snippets and instant messages. This form of data rarely contains repeated word. It presents challenge in sentences similarity analysis as the standard text similarity models merely rely on the number of word occurrence, often resulting unreliable similarity value. Besides, the use of abbreviation, acronyms, slang, smiley, jargon, symbol or non-standard short form also contributes to the difficulty in similarity analysis. Thus, an extended ensemble similarity model approach is proposed. An experimental study has been conducted using datasets of English short sentences. The findings are very encouraging in improving the similarity value for short sentences.

To review researcher’s attempts in response to the problem of spoofing and liveness detection, mapping the research overview from the literature survey into a suitable taxonomy, exploring the basic properties of the field, motivation of using liveness detection methods in face recognition, and Problems that may restrain the advantages. We presented a subjected search on face recognition with liveness detection and its synonyms in four main databases: Web of science, Science Direct, Scopus and IEEE Xplore. We believe that these databases are widely inclusive enough to cover the literature. The final number of articles considered is 65 articles. 4 of them where review and survey articles that described a general overview about liveness detection and anti-spoofing methods. Since 2012, and despite of leaving some areas unestablished and needs more attention, researchers tried to keep track of liveness detection in several ways. No matter what their category is, articles concentrated on challenges that faces the full utility of anti-spoofing methods and recommended some solutions to overcome these challenges. In this paper, different types of liveness detection and face anti-spoofing techniques are investigated to keep researchers updated with what is being developed in this field.
Sleep Spindle-dependent Functional Connectivity Correlates with Cognitive Abilities
Authors: Fang Zhuo , Ray Laura B. , Houldin Evan , Smith Dylan , Owen Adrian M. , Fogel Stuart M.
Published: October 2019

EEG studies have shown that interindividual differences in the electrophysiological properties of sleep spindles (e.g., density, amplitude, duration) are highly correlated with trait-like “reasoning” abilities (i.e., “fluid intelligence”; problem-solving skills; the ability to employ logic or identify complex patterns), but not interindividual differences in STM or “verbal” intellectual abilities. Previous simultaneous EEG-fMRI studies revealed brain activations time-locked to spindles. Our group has recently demonstrated that the extent of activation in a subset of these regions was related to interindividual differences in reasoning intellectual abilities, specifically. However, spindles reflect communication between spatially distant and functionally distinct brain areas. The functional communication among brain regions related to spindles and their relationship to reasoning abilities have yet to be investigated. Using simultaneous EEG-fMRI sleep recordings and psychophysiological interaction analysis, we identified spindle-related functional communication among brain regions in the thalamo-cortical-BG system, the salience network, and the default mode network. Furthermore, the extent of the functional connectivity of the cortical–striatal circuitry and the thalamo-cortical circuitry was specifically related to reasoning abilities but was unrelated to STM or verbal abilities, thus suggesting that individuals with higher fluid intelligence have stronger functional coupling among these brain areas during spontaneous spindle events. This may serve as a first step in further understanding the function of sleep spindles and the brain network functional communication, which support the capacity for fluid intelligence.
Nationalist Sentiments Obscured by ‘Pejorative Labels’
Authors: Bumochir Dulam
Published: October 2019

This paper aims to unveil sources of nationalist sentiments that are often disregarded, in part because they are often given ‘pejorative labels’ such as ‘populist’ and ‘resource nationalist’ by those who promote the market economy and mining industry. Anthropologists can extend their research beyond such labelling and find out what is at the origin of such popular mobilisations and consequent political decisions against mining. I find that the culturally accepted term nutag, which means birthplace, homeland and country of origin, is the basic source of nationalist sentiments that resist mining. The term nutag has evolved from meaning one’s naturally related birthplace to referring also to the politically independent country of Mongolia. The ideas associated with the original meaning make such nationalist sentiments different from, and much broader than, the idea of controlling natural resources indicated by the term ‘resource nationalism’.

The Failure of Dilma Rousseff’s Developmentalist Experiment: A Class Analysis
Authors: Singer André
Published: October 2019

There are various reasons for the dissolution of the productivist coalition and the formation of an antidevelopmentalist bourgeois united front during Dilma Rousseff’s first term. With the intention of accelerating the pace of Lulism, Rousseff actively opposed neoliberalism, but state intervention alienated the industrialists even though, paradoxically, it aimed to favor them. On a small scale, Rousseff’s developmentalist experiment may have followed in the footsteps that led to the 1964 military coup.

Diferentes razões apontam para a dissolução da coalizão produtivista e a formação de uma frente única burguesa antidesenvolvimentista durante o primeiro mandato de Dilma Rousseff. Com a intenção de acelerar o passo do lulismo, Dilma se contrapôs ativamente ao neoliberalismo, mas a intervenção estatal alienou os industriais, apesar de, paradoxalmente, tentar favorecê-los. Em ponto pequeno, o ensaio desenvolvimentista de Dilma pode ter seguido as pegadas que resultou no golpe de 1964.
Good intentions meet harsh realities: Social dialogue and precarious work in industrial cleaning
Authors: Larsen Trine P , Mailand Mikkel , Schulten Thorsten
Published: October 2019

This article offers a comparative study of recent joint initiatives by Danish and German social partners within the industrial cleaning sector. It examines how, and to what extent, the day-to-day realities of industrial cleaners vary due to distinct regulatory regimes and explores why social dialogue initiatives have not had a greater impact in terms of improving wages, working conditions and social benefits. The authors find that, whilst sector institutions help counteract precariousness for some cleaning workers, the increasingly intense competition within industrial cleaning contributes to increased segmentation as employers seek various loopholes within existing labour market regulation to cut costs. Therefore, the labour force within the cleaning sector is increasingly segmented, with some cleaners ending up in highly precarious situations, whilst others are helped by various joint initiatives by social partners to improve atypical workers’ conditions.
Protection Order Policy-making in the U.S. State Courts of Last Resort from 1980 to 2019
Authors: Barrick Andrea , Kilwein John C.
Published: October 2019

This article examines the development of policy designed to target intimate partner violence, or domestic violence, through the use of protection orders in the U.S. state courts of last resort, or the state supreme courts, from 1980 to 2019. The authors’ study shows that the American state supreme courts are decidedly supportive of female protection order litigants throughout the period studied. The model also highlights the importance of state government ideology, percentage of female justices, and state laws that ban gender hiring discrimination on state supreme court decision-making in these cases.
The Best Words: Linguistic Indicators of Grandiose Narcissism in Politics
Authors: Underberg James E. , Gollwitzer Anton , Oettingen Gabriele , Gollwitzer Peter M.
Published: October 2019

At a 2015 campaign event, Donald Trump claimed, “I have the best words.” While remarks like these have inspired extensive commentary on grandiosity in politics, few studies have investigated how grandiosity manifests in political speech. This research finds that grandiose U.S. presidents ( n = 35) use words differently than their humbler presidential counterparts, and differently than other grandiose individuals, including by using more “we-talk.” We theorize that grandiose individuals adjust their language based on context to find “the best words” for a particular audience.
Bullet Screens (Danmu): Texting, Online Streaming, and the Spectacle of Social Inequality on Chinese Social Networks
Authors: Cao Xuenan
Published: October 2019

For theorists interested in screen cultures and the digital economy, looking beyond Facebook and YouTube prompts a more refined conceptualization of participation and monetization on social networks. This paper examines YY as representative of Chinese platforms that monetize spectacles of social inequality. I first discuss why these financially successful platforms have eluded the attention of media and cultural critics, and then explain how these social network platforms blend subversive texting with streaming through a format called ‘bullet screen’. This format collapses social inequality into a spectacle of money flowing and vanishing on screen. This investigation contributes to the theoretical discussion of mixed-semiotics, reorients several Marxian neologisms and explains what texting means on screen in both semiotic and economic terms.
‘. . . and then no more kisses!’ Exploring patients’ experiences on multidrug-resistant bacterial microorganisms and hygiene measures in end-of-life care A mixed-methods study
Authors: Heckel Maria , Sturm Alexander , Stiel Stephanie , Ostgathe Christoph , Herbst Franziska A , Tiedtke Johanna , Adelhardt Thomas , Reichert Karen , Sieber Cornel
Published: October 2019

Background:

In end-of-life care hygiene, measures concerning multidrug-resistant bacterial microorganisms may contradict the palliative care approach of social inclusion and be burdensome for patients.

Objectives:

To integrate patients’ perspectives on handling multidrug-resistant bacterial microorganisms at their end of life, their quality of life, the impact of positive multidrug-resistant bacterial microorganisms’ diagnosis, protection and isolation measures on their well-being and patients’ wishes and needs regarding their care.

Design:

A mixed-methods convergent parallel design embedded quantitative data on the patients’ multidrug-resistant bacterial microorganisms’ trajectory and quality of life assessed by the Schedule for the Evaluation of Individual Quality of Life in qualitative data collection via interviews and focus groups. Data analysis was performed according to Grounded Theory and qualitative and quantitative results were interrelated.

Setting/participants:

Between March 2014 and September 2015 at two hospitals adult patients diagnosed with multidrug-resistant bacterial microorganisms and treated in a palliative care department or a geriatric ward were included in the sample group.

Results:

Patients in end-of-life and geriatric care reported emotional and social impact through multidrug-resistant bacterial microorganisms’ diagnosis itself, hygiene measures and lack of information. This impact affects aspects relevant to the patients’ quality of life. Patients’ wishes for comprehensive communication/information and reduction of social strain were identified from the focus group discussion.

Conclusion:

Patients would benefit from comprehensible information on multidrug-resistant bacterial microorganisms. Strategies minimizing social exclusion and emotional impact of multidrug-resistant bacterial microorganisms’ diagnosis in end-of-life care are needed as well as adaption or supplementation of standard multidrug-resistant bacterial microorganisms’ policies of hospitals.
