Published: July 2019

In the recent era facial image processing is gaining more importance and the face detection from image or from video have number of applications which are video surveillance, entertainment, security, multimedia, communication, Ubiquitous computing etc. Various research work are carried out for face detection and processing which includes detection, tracking of the face, estimation of pose, clustering the detected faces etc. Although significant advances have been made, the performance of face detection systems provide satisfactory under controlled environment & may get degraded with some challenging scenario such as in real time video face detection and processing. There are many real-time applications where human face serves as identity and these application are time bound so time for detection of face from image or video and the further processing is very essential, thus here our goal is to discuss the face detection system overview and to review various human skin colors based approaches and Haar feature based approach for better detection performance. Detected faces tagging and clustering is essential in some cases, so for such further processing time factor plays important role. Some of the recent approaches to improve detection speed such as using Graphical Processing Unit are discussed and providing future directions in this area.

Published: July 2019

Micro-electro-mechanical system (MEMS) is a hybrid technology that combines electronic, electric and mechanical technology in a micron-size system. This allowed for higher performance and multifunction devices fabricated at much lighter weight and cost effective. One of the major application of MEMS is in sensor devices area. This paper highlight the simulation study of a typical moisture sensor fabricated from Tungsten Interdigitated (IDE) MEMS device. Using COMSOL Multiphysics software, the moisture sensor was modelled based on the current material and physical dimension and layout. The model then go through validation proses to its sensitivity performance against the experimental result. Subsequently, the optimization on sensor sensitivity was carried out by varying the model parameters including the sensor physical dimension, working temperature and humidity. The simulation result suggest that the sensor sensitivity is highly correlated to the electrode distance value. The average sensitivity of the sensor improved to ~48% better when the distance between reduced to 50% from 6 micron to 3 micron tested at temperature between 25 ÌŠ C to 45 ÌŠ C. This information is valuable as the input to the sensor designer in finalizing the MEMS physical layout in producing highly sensitive moisture sensor devices.Â Â

This study aims to demonstrate that a comprehensive one-dimensional model of the arterial network can be used in conjunction with the generalized transfer function (GTF) technique to estimate central aortic pressure using pressure waveforms obtained from peripheral sites. The peripheral and central pressure waveforms for a healthy subject are used to estimate transfer functions, which are then used to reconstruct central aortic pressure waveforms for a second model that simulates arterial stiffening. The similarities between the simulated aortic waveform and the waveforms estimated using the transfer function are and Â from the brachial, carotid and iliac arteries, respectively. The root-mean-square errors (RMSE) for the reconstructed waveforms from the brachial, carotid and iliac arteries are and Â mmHg, respectively. The results from this study illustrate that the proposed method provides a feasible alternative to higher dimensional models as well as experimental studies and can greatly enhance the accuracy of central aortic pressure estimation.Â Â Â Â Â

Authors: Faizal Hakim Hidzir Mohd , Imran Sainan Khairul , Husain Hazran 
Published: July 2019

A standpipe is a component that functions to remove the condensate of gas from the oil that flows inside the O&G piping system underneath. Efficient gas removal promotes better crude oil quality and increases productivity. The deflector plates integrity in a stand pipe, where thin plates are mounted on the pipe walls periodically in the direction of fluid flow, has been numerically investigated. The aim of this investigation is to determine how the working fluid density and deflectors thickness influenced the plates integrity. Two working fluids were tested. Natural gas and crude oil which has a higher density. The thickness of the plates was 3 mm and 6 mm. A series of simulation analyses were done analytically through CFD and FEA simulation method using ANSYS software. Based on the results, crude oil produces higher stress onto the plates. This causes large plate deflection. It was observed, the plates near to the standpipe inlet were subjected to the highest stress. Stress on the deflector plates drops as the fluid travel along the pipe height. The deflector plates of 3 mm were failed under these conditions and were not recommended for usage.

The search for new drivers for the development of the Russian Federationâ€™s regions from the point of view of innovative transformations is currently relevant. In the current economic conditions, the role of the higher school in the training of demanded personnel is growing. Today, the university can and should become a reliable integrator of the business environment with state and municipal authorities. For the consortium of business environment, state authorities and universities, today there are significant barriers due to lack of infrastructure, good legal support, transparency of communication, sources of financing, etc. In order to optimize this process, the paper proposes the AUB polycentric partnership model, which will ensure free entry to and exit from the consortium, attracting the maximum number of participants, taking into account the elimination of possible risks.Â Â

Published: July 2019

Searching for mineral and energy resources in various regions of the Arctic basin has revealed the presence of huge reserves of oil, gas and other extractable resources. The coast of the Arctic Ocean, i.e. the European and the Asian north of Russia turns into the region of active economic development.Population migration flows into these regions will increase every year. People will move from the favorable climatic conditions to the extreme conditions of the Arctic. The harsh conditions of the Arctic are particularly heavy for the weather sensitive people with increased excitability of the central nervous system.In the extreme weather conditions, food is the most important means of organism protection. Therefore, a balanced diet is the most important means of human adaptation in the northern latitudes, with bee-farming products playing a huge role [4, 7].The Great Vasyugan swamp is the largest swamp with the area of 53,000 km2. It covers the Ob-and-Irtysh watershed, and stretches within 55040Ê¹â€“58060Ê¹ N and 75030Ê¹â€“83030Ê¹ E; its southern border stretches 573 km from the right bank of the Irtysh River to the left bank of the Ob River. From the southern border to the north, the swamp stretches for 320 km. In this area, there are huge reserves of peat, which make over 61% of the total stock in Russia. Among the swamp, there are islands, i.e. spaces not occupied by swamps and lakes, and covered with forest and grass [2].In the Tsarist times, the Vasyugan swamp was considered unsuitable for agriculture. Development of this region started after the October revolution. People grew gray cereals, fodder crops, potatoes, and vegetables. In this area, local horse breed named â€œnarymkaâ€ was bred.After the Great Patriotic war, the Vasyugan Plain, or the Narym territory was deserted. Settlements were removed, and bushes and grass started growing in their place.Currently, the Great state program for studying the Narym territory has been started for using these areas to grow agricultural products to be supplied to the population of the Arctic Belt.Â Â

Published: July 2019

Article considers Adyghe (Circassian) religiosity and its reproduction in contemporary prose. Conducted study and a variety of problems in this case are rare, besides, almost complete cancellation of any research activity in today's Russia is known. And the problems are not studied enough. Therefore, the relevance of the selected topic is undoubtedly important, and we are developing it using a number of analytical and synthetic methods inherent in humanitarian knowledge. In the course of research, we established that the fact that both religions common today (Christianity, Islam) are not at all sources of interethnic difficulties, and concluded that the state must strive to support the existing religious branches (in particular, Islam and Christianity). The relevance of this work is that the problems in this field are too little studied, and our research provides new data, as well as a new look at this topic.Â Â

Published: July 2019

The article is concerned with methodological approaches to development strategies for tourism and hospitality industry enterprises. It has been found that most regions, local tourist destinations, tourism and hospitality industry businesses do not have any clear formalized strategy. It was determined that some tourism and hospitality industry businesses apply only individual elements of strategic management, i.e. do not have an integrated system of strategic management. Methodological tools have been proposed for elaborating development strategies for tourism and hospitality industry enterprises, which show that strategic management, which is methodological by nature, i.e. is characterized by the conceptual approach and panoramic vision, cannot give an exact and clear view of the tourism industryâ€™s future. It was proved that strategic management cannot be limited to a set of universal and routine rules, procedures or schemes. It was defined that strategic management requires great efforts, time and resources to make the activity of tourism and hospitality industry businesses remarkable.Â Â Â
