Professional expectations of migrants with varying degrees of resilience
Authors: Aleksanova Ol'ga Ye.
Published: December 2019

The article is devoted to the study of the impact of the resilience of Greek migrants on their expectations for future employment in connection with resettlement to permanent residence on the territory of the Russian Federation. The survey was applied on two original questionnaires and psychological testing (a questionnaire of resilience; methods of assessment of job satisfaction; scale of satisfaction with life). Some differences in the expectations of migrants are established. Thus, persons with a high degree of vitality are focused on the fact that the future work would be pleasing, stable, and there would be career prospects. Migrants with a low degree of resilience rely on a special social status of work and a good relationship with the leader. The general pattern is that resilience gives workers labour mobility, potentiates their confidence in the correctness of the decision on migration. Ultimately, migrants linked their lives to the host country through work.

FRICTION AMONG THE THREADS OF WEAVING FABRICS DURING THEIR ELONGATION
Authors: Sevost'yanov P. A. , Tikhomirova M. L.
Published: December 2019

The article analyses the role of friction between the warp and weft threads in the canvas. A mathematical model of the influence of friction forces on the elongation of the main thread and the mutual displacement of the warp and weft threads in plain weave is proposed. The features of the dynamics of the propagation of deformation along the warp threads as a result of the influence of friction forces are established. It is shown that at low friction forces between the warp and weft threads, the system behaves as a two-point quasilinear oscillator, the movement of which is a beat with oscillations at the fundamental and combined frequencies. With an increase in the friction forces, the randomness of motion in the places where the filaments overlap increases and with a further increase in their vibrations, the vibrations disappear, the fabric structure behaves as a whole. The calculation of the warp thread deformation taking into account the friction forces against the weft thread showed that the friction forces significantly affect the displacements of the thread sections when it is elongated, and the effect of chaotisation of the shift of the thread sections, which is certainly transmitted back to the weft threads, arises.

Competitive Environment and its Impact on Business Climate Development in a Region
Authors: Zyus’kin A. A.
Published: December 2019

The presented study examines the business climate of the Smolensk region, with applied developments based on the material of this region.

Aim. The study aims to characterize the specific features of ‘competitive environment’ as an economic category in the context of formation of a favorable business climate within the region.

Tasks. The authors analyze theoretical approaches to the definition of ‘competitive environment’ and ‘business climate’; assess the state of the competitive environment as a factor affecting the business climate in the region (through the example of the Smolensk region) with allowance for the competition intensity rating and survey of entrepreneurs; examine the implementation of government initiatives aimed at forming a favorable competitive environment in the Smolensk region; formulate proposals to improve the efficiency of implementation of measures by the local authorities of the Smolensk region aimed at forming a favorable competitive environment.

Methods. This study uses general scientific methods of cognition to examine the factors of formation of a favorable business climate in various aspects and to identify trends in the current state and development of entrepreneurship in the region.

Results. Analysis of measures taken by the authorities of the Smolensk region to implement a government competitive policy and qualitative assessment of the competitive environment in the region by the business community show that changes and adjustments to the regulatory framework are not introduced quickly enough, while entrepreneurs show a low level of awareness about the activities of the authorities in enhancing competition. A potential solution to this problem involves creating a Competition Development Project Office in the region, which would unite representatives of the authorities, including employees of the Office of the Federal Antimonopoly Service (OFAS) in the Smolensk region, natural monopolies, and entrepreneurs (by including representatives of associations and business communities). Establishment of such an office would make the decision-making more balanced and immediate, which would in turn improve the quality of the competitive environment in the Smolensk region.

Conclusions. The authors propose assessing the quality of the competitive environment, ranking regions, and including the results into the annual report of the Federal Antimonopoly Service (FAS) on the state of competition in Russia. Improvement of the business climate is identified as a priority for regional authorities. Therefore, monitoring and evaluation of the business climate and its factors is an essential task.

Cryptographic hash functions are used in many applications. One important application is to ensure data integrity. Although there are many different types of hashing algorithms, MD5 is widely used to ensure data integrity in digital evidence. However, a weakness, where collisions can occur, has been found in the MD5 algorithm. With regards to digital evidence, this is a big issue. The integrity of the digital evidence becomes questionable due to collisions and hence it is not admissible in court. Many methods were used to find collisions, such as the Chosen-Prefix Collision and researchers have been improving collision finding algorithms. This paper concentrates on reducing the chances of collision by chopping the last 16 bits of the MD5 algorithm and injecting timestamp into the chopped parts. Experiments are performed to test this algorithm and the results show that the time taken to find collisions is longer using the MD5 with an injected timestamp. The chopping construction and the timestamp disrupt the iterative property of the hash function thus when dealing with digital evidence, there are less chances of hash collision and therefore the probability of the admissibility of the digital evidence in court is higher.

Abstract: Secure Data Aggregation in Wireless Senor Networks (WSNs) is a challenging issue. The various protocols has been suggested in the recent past such as EDIT[13], ADA[8], TSDA[9], SEDAN[10]. These protocols effectively meet the constraints of WSNs. In this paper, we have proposed a Fuzzy Based Secure Data Aggregation protocol (FSDAP) which is an efficient localized protocol. The FSDAP protocol is designed with three phases. The first phase selects Aggregator Node using ANS algorithm. An ANS algorithm involves two steps to elect an Aggregator Node in the clustered network. In first step, the cluster head is selected based on the Euclidean distance and in second step, the cluster head is selected based on the fuzzy product and fuzzy value (α). Then, in second phase, a selected AN eliminates data redundancy sensed by all sensor nodes within the cluster. Finally, in third phase, the FSDAP protocol effectively detects malicious node and provides secure data transmission path. Thus, the proposed protocol, FSDAP utilizes the node’s resource parameter uniformly, which in turn improves Network Lifetime, maximizes Throughput Rate, maximizes Packet Delivery Ratio and minimizes End-to-End Delay. The FSDAP is simulated using the NS2 simulator and compared with centroid algorithms Fuzzy C-Means and K-Means algorithm and a secure aggregation protocol implemented using SAR (Secure Aware Ad hoc Routing). The time complexity of FSDAP protocol is O(m2n).

The use of piezoelectric energy harvesters in low frequency applications is a classic problem due to the high elastic modulus of currently available piezoelectric materials. Furthermore, the output power is proportional to the third power of the excitation frequency. Higher excitation amplitudes or an increase in the piezoelectric material can produce a high output power. However, this is not feasible for weak environmental vibration, and using more piezoelectric material would incur a higher cost so this is not an attractive option. This article proposes an L-shaped piezoelectric energy harvester that amplifies the excitation amplitude with the aid of an extension arm. The effects of bending and rotational inertia are considered when modelling the open-circuit voltage that can be generated by the harvester. Experimental validation is carried out using zinc, aluminium and galvanized steel extension arms. The prediction model provides a good estimation of the results with acceptable error percentages for linear elastic extension arms. It is found that the proposed harvester geometry generates more output voltage for all lengths of extension arm, and the optimum lengths are different for each material. The use of a zinc extension arm generated 290 μW at 49 Hz, which is 55% greater than the power generated by a harvester without an extension arm that had a power density of 1.41 μW/mm3.

The world continues to search for renewable energy resources, due to the devastating effect of global warming and the dwindling resources of fossil fuels. Without needing much modifications to the existing diesel engines, biodiesel is regarded as one of the most promising ways to treat these two issues simultaneously. However, the production of biodiesel is always associated with a higher cost compared to its counterpart; the petroleum-derived diesel. In addition, the type of feedstock used in the production of biodiesel also has also become a big concern due to the never-ending fuel vs food debate. Jatropha curcas is a second generation feedstock which can be specifically grown to avoid the usage of edible oils as feedstock to produce fuel. In this paper, the energy saving potential of using elite Jatropha curcas hybrid for biodiesel production in Malaysia are evaluated by conducting a full chain energy analysis. It was found that the new hybrid consumed 25.32 MJ of energy in order to produce 1kg of biodiesel. The net energy balance (NEB) and net energy ratio (NER) when by-products are not utilized are found to be 15.89 MJ/kg and 1.63, respectively. However, the NEB and NER increase to 26.72 MJ/kg and 2.84 when the by-products are used in the biodiesel conversion process. Hence, this new hybrid of Jatropha curcas has a huge potential to be used for the production of biodiesel.

This paper reviews the piezoelectric energy harvesting from mechanical vibration. The recent development in the microelectronic devices and wireless sensor networks (WSNs) requires continuous power source for better performance. Many researchers have been done to develop a permanent portable power source for microelectronic devices. Micro energy harvesting (MEH) consists of two basic elements; freely available energy and transducer. Energy is everywhere around us in different forms. The energy conversion ability of piezoelectric energy harvester is high among different MEH techniques. A cantilever type piezoelectric energy harvester under different shapes is mostly studied in the last few years. The output of piezoelectric harvester depends upon the deflection produced, more deflection led to more electrical output. The deflection in cantilever beam under different shapes is different. This review paper presents a comparison of different piezoelectric cantilever beam shapes and output generated analyzed in the last decade.

Small scale hydropower is among the most attractive and cost-effective sustainable energy technologies available, by harnessing electricity through moving water. Naturally, moving water can be found in rivers and also man-man conduits where there is a continuous water flow. The sewage treatment facility has continuous water flow at the effluent pipe that can generate electricity by means of small-hydropower system. However, there are no sewage treatment plants (STP) in Malaysia that reclaim the energy through the usage of water turbines. This study is conducted to evaluate the feasibility of a micro-hydropower (MHP) system at the continuous flow of effluent discharge point of domestic STP that comprises of a low head with high flow fluctuations. This work comprises of evaluation of the potential power output of MHP generator which attached to different type of STP. The work starts with selection of a five STP which have maximum current population equivalent (PE) over design PE loading ratio. Next, the effluent discharge flow rate & outfall head are collected and recorded. Finally the potential output power for all selected STPs is calculated.

Earthing system is very important in order to protect the electrical equipment as well as the human’s safety against over voltages. The main function of the earthling system is to remove unwanted excessive electrical currents caused by unusual conditions such as fault and lightning or switching over voltages by providing a low resistance path to the earth. Researchers had studied the behaviour of the earthling system to improve its performance for the past few years. There are few factors that influence the performance of the earthling system such as soil resistivity and soil ionization which need to be focused in order to improve the earthling. Thus, this paper evaluates on the factors that affect the behaviour of the earthling system based on simulation works using MATLAB and Safe Grid Software. Some analytical calculations are used to obtain the soil resistivity and resistance as well as the touch and step voltages. The simulation results were validated based on comparison with other studies on the factors that influence the earthling system performance. The results reveal that the variation of soil resistivity, the configuration of electrodes, current magnitude and frequency dependence can result in a change of transient response of the systems.

Natural fibre is being studied and used as sound absorber for its promising acoustic properties. For instance, Germany have commercial plants that are producing sound absorbers from natural fibre. Natural fibre is eco-friendly and has no effect on human health. Besides that, the production cost of natural fibre is cheaper than synthetic fibre. This research reported the thickness effects on acoustic properties in different ratios of natural fibres of empty fruit bunch (EFB) and oil palm frond (OPF). Four different thickness of low density fibre board (LDF) have been fabricated (12 mm, 14 mm, 16 mm and 18 mm) in density of 120 kg/m3. The Sound Absorption Coefficient (SAC) was tested by using the Impedance Tube Method (ITM) according to ASTM E1050-98 standards at frequency from 0 Hz to 6400 Hz. The results show the values of SAC for all samples increase with increasing in thickness from frequency range of 0 Hz – 4500 Hz. It is noteworthy that the LDF with thickness of 16 mm and 18 mm can be classified as Class A sound absorbing material according to sound absorption classes and possess the SAC values of 0.8 and above at a wider frequency range, which is 2500 Hz to 6400 Hz. The combination of EFP and OPF natural fibres has a very promising and excellent performance in acoustic properties.
