Authors: Hanif Mat Muhammad Mohd , Mohd Ihsan Mamat Aman , Saiful-islam Wan Salim Wan
Published: July 2018

With such tough legislation on current emission standards, car manufacturers are focusing on increasing the efficiency of their engines with the development of advance waste heat recover (WHR) technology. Organic Rankine Cycle (ORC) and Electric Turbo Compounding (ETC) system have a good potential to be used as exhaust energy recovery. This paper compares the exergy availability and losses between the ORC and the ETC. In this particular study, exhaust data from the Proton 1.6L CamPro CFE turbocharged engine was used. This particular engine already has a main turbocharger, making the added WHR as a secondary recovery system to further increase the engine efficiency. Both systems are coupled to a 1 kW electric generator for ease of comparisons. At first the available exergy is calculated for both WHR technologies. Exergy losses from rotating the generator are analysed to finally determine the thermal efficiency of the overall system. Exergy calculation is simplified to only account for chemical and physical exergy since kinetic and potential energy are negligible in comparison. Available exergy for ORC was significantly high which went up to 12.5 kW with the exergy losses recorded at 9.7 kW. The ETC achieved only 5 kW but had a small loss at 8x10-3 kW. Average thermal efficiency of the ORC systems was 10.7% compared to ETC which was 58.7%.  It can be concluded that the complexity of the ORC system contributes to its downfall where multiple components increase its exergy losses compared to the simplistic design of an ETC.

Published: July 2018

One of the most favoured material in bone tissue engineering field nowadays is hydroxyapatite (HA), which is also known to be bioactive and has a similar composition to human bone. However, developing an artificial bone or bone graft using biocompatible HA is a challenging task due to the lower strength of the main substance. To improve the mechanical properties of synthetic HA, introduction of metallic substance such as magnesium (Mg) into HA has been proposed. In this present study, 0, 10 15 wt% of magnesium hydroxyapatite (MgHA) nanopowders were prepared by a simple wet precipitation method. These nanopowders were then compacted using a 10-ton compression uniaxial press machine with 150 MPa pressure to form a disc shape of dense MgHA. After that, the MgHA discs were sintered at a temperature of 1000 °C and 1100 °C to remove the organic compounds and further densify the ceramics. XRD results showed that the crystallinity of MgHA increased when the sintering temperature increases. The compression test showed that the 10 wt% MgHA sample recorded the highest compressive strength (243.59 MPa) when sintered at 1100 °C, while pure HA has the lowest value with 49.37 MPa. This study also demonstrates that sintering temperature at 1100 °C gives significant improvement to the mechanical properties of the MgHA dense bodies compared to sintering at 1000 °C.

Published: July 2018

A risk assessment practice determines the risk both quantitatively and qualitatively, such that risks are analysed and assessed thoroughly. Several methods are available to mitigate the failures in a construction project. This project focuses on identifying risks and mitigating them to reduce failures. On a questionnaire basis, a survey from various employees working on different projects is conducted by considering seven major factors of risks and the normalised score of each factor is ranked. Based on the normalized score values, least three risk factors were identified and Analytical Hierarchy Process(AHP) is applied by manual calculations. AHP is based on human judgements and objective evaluation, which examines the consistency of the evaluation by Eigen values. Validation of the identified factors is also done through MAT Lab and is compared with the manual method. Consistency and hierarchy of the identified factors has been found out, thereby mitigating the failures and increasing the efficiency of the projects.

Published: July 2018

Social media is an interactive personal tool to articulate an individual's cognizance. This project involves one such micro blogging platform, Twitter. Trends can simply be defined as the frequently mentioned topics throughout the stream of user activities. Mining twitter data for identifying trending topics provides an overview of the topics and issues that are currently popular within the online community. Therefore, the most effective and suitable methodology should be implemented to identify the short term high intensity discussion topic. The trigrams or higher order n-grams are used to determine the trending topic. Twitter Streaming API is used to collect data from the Twitter accounts using API keys and the formatted tweets are stored in a non SQL database. Subsequent steps include data cleansing followed by stemming. The processed data is subjected to trend prediction algorithms like DB Scan, Frequent Pattern Mining, Trees(fuzzy/inductive/decision), Soft frequent pattern mining and empirical statistics such as Frequency metric, TF-IDF, Normalized term frequency and Entropy based on the key parameters to identify the most trending event within a period of time. Thus, the trending topics can be detected with a reasonably close approximation to the expected outcome.  This can be used in detecting and predicting events for an early warning system (or) prediction tools and also artificially intelligent services like web search system or recognition systems.

Published: July 2018

Fracture energy is the post-crack energy absorption ability of the material that represents the energy absorbed by the structure at the time of failure. Its analysis has gained importance and hence requires a powerfulmethod for its development. A two parameter Weibull distribution proves to be an efficient tool in analysing the scattered experimental test results. In this paper, the specific fracture energy of plain concrete and concrete reinforced with natural fibres of hemp, wheat straw and elephant grass are statistically analysed by two parameter Weibull distribution by using graphical method. For determining Weibull parameters, 21 equations have been used and the best equation is taken for the reliability analysis. A Weibull reliability curve is plotted, which shows the specific fracture energy at each reliability level. This curve enables an engineer to choose the fracture energy of a particular mix based on its reliability requirement and safety limit. Therefore, reliability curves are a pioneer in statistical analysis as they eliminate the time-consuming and costly experimental process. This method can be applied in areas with similar uncertainties.

Published: July 2018

In the recent trend of changing environment, the rainfall and the inflow to the reservoir are getting reduced year by year respectively in agricultural field and in river basins. In this paper the dependable inflow into the reservoir and the rainfall in the command area is estimated with the past 30 years data. The statistical methods and formulae (Variance, Mann- Kendall method) are used to determine the dependable inflow and rainfall for both the monsoons. It is found that the inflow is not dependable for South –West monsoon, to do the agriculture, for a normal crop, with medium water requirement.. For the North - East monsoon both the inflow and rainfall are dependable hence the agriculture can be carried out with a single crop (paddy) having more water requirement (or) possible multi-crops, according to the storage in the reservoir and prediction of rainfall in that season. The deductions for other requirements of the dam, losses for evaporation, conveyance etc has been taken into account. The case study is done with the data for 30 years (1982-2012)for a dam in Tamil Nadu, India.

Analysis and comparison of fast multiplier circuits based on different parameters
Authors: Aaron D’costa Mr , Abdul Razak Dr , Shazia Hasan Dr
Published: July 2018

Digital multiplier circuits are used in computers. A multiplier is an electronic circuit used in digital electronics to multiply two binary numbers. Multiplier circuits are used in ALU for binary multiplication of signed and unsigned numbers. The delay, area and power consumption are the 3 most important design specifications a chip designer has to consider. Delay of the circuit is directly proportional to the delay of a multiplier. Increased delay in the multiplier leads to higher delay in the circuit. Therefore research is carried out as to how to reduce the delay of the multiplier block so as to reduce the delay of whole circuit. The main purpose is to deal with high speed and lower power consumption even after decreasing the silicon area. This makes them well-suited for numerous complex and convenient VLSI circuit implementations. The fact however, remains that area and speed are two contradictory performance restrictions. Hence, increase in speed always results in the use of more and complex hardware. Different arithmetic techniques can be used to implement different multiplier circuits. The focus of this paper is to implement various multiplier circuit and compare them. The timing signals can be observed using software such as Modelsim and Xilinx.

Authors: Shkurupiy Oleksandr , Mytrofanov Pavlo , Masiuk Vladislav
Published: July 2018

The paper presents an algorithm for calculating the stability of the equilibrium form of the first kind of compressed discrete systems by the displacements method in combination with the methods of iterations and bisection. The use of the methods makes it possible to effectively determine the minimum critical stress or strain at the first bifurcation and their corresponding form of stability loss, both for statically determined and statically undetermined systems. This approach, using matrix forms, makes it possible to significantly simplify the calculations of the analytical condition for the stability loss of compressed discrete systems (the stability loss equation), which has high orders, as well as to construct the form of stability loss corresponding to a critical load, that is, to solve the problem of loss of equilibrium stability. The calculation actually leads to solving a nonlinear transcendental equation, which is the equation of stability loss. The difficulty lies in the absence of an analytical solution of such an equation due to the presence of complex of Zhukovsky functions, which have transcendental functions in their structure. Such solution can be performed only with the use of numerical methods. This algorithm for calculating the loss of equilibrium of the first kind of compressed discrete systems by displacement in combination with the methods of iteration and bisection is implemented in the software complex "Persist" for PC in Windows OS. The program was approbated and implemented in the educational process at the Department of Structural and Theoretical Mechanics of Poltava National Technical Yuri Kondratyuk University during the training of specialists in engineering specialties.

The mobile unbalances by means of independent external action, that is caused by mechanism for managing of mobile unbalances, have an opportunity to change synchronously its positions on the unbalanced shaft directly in time of mixer’s work. The centrifugal inertia forces of inflexible and mobile unbalances make the dynamic wrench that consists of the main vector

 and the main moment

 and rotates with unbalanced shaft. It is determined that the value of the main vector

 and the main moment

 evaluate the dynamic action of this vibration exciter to the mixer’s working container. The mathematical model of the dynamic action of oscillator exciter on the processed medium of mixer with the toroidal working container is received. Depending on the value of turn angle of mobile unbalances from its starting positions exciter: a) staying in the dynamic balance state; b) is generating the translation force field; c) generates the wrench force field of this or that direction. These opportunities of controlled vibration exciter firmly provide anfractuous circulative motion of the processed medium on the volume of the mixer’s working container. Using of controlled exciter also leaves out the transfers through intermediate resonance frequencies. As its starting and stopping happen in a dynamic balance state, so it leaves out the possibility of manifestation of the “Sommerfeld’s effect” that is harmful for the driven motor, improves the constructive availability of the vibration mixer and increases its efficiency and life duration.

Authors: Kariuk Alla , Koshlatyi Oleg , Mishchenko Roman
Published: July 2018

The article demonstrates the methodology and the results of statistical characteristics determination and territorial distribution as well as free air winter temperature calculated values required for the designing the building`s cladding.Daily temperatures of free air have been described by a probabilistic model of quasi-stationary differentiable random process. The expectation function is set by the Fourier series or sequence of monthly temperatures, the standard and asymmetry are determined by the mathematical expectation. The Ordinates Distribution Law is described by a linear combination of Gauss and Gumbel distributions. The frequency structure is determined by the time-constant value of the effective frequency. The required statistical characteristics are determined by the results of systematic measurements of average daily air temperature at 485 observation points inUkraine.The calculated values of winter air temperature are determined by using probabilistic approach with accounting for return period equal to building working life, as well as temperature averaging interval, reflecting building`s cladding thermal inertia. The map of territorial distribution of Ukraine has been created based on free air temperature values and dependencies which can lead to calculated values taking into account given building operating life, temperature averaging interval and altitude in mountainous regions.The developed methodology ensures the possibility of minimal calculated values determination for free air temperatures including all the factors mentioned above, and the suggestions as for introduction of norms enabling accounting for building`s cladding thermal inertia within the building working life  when making thermotechnical characteristics calculations.

The article is aimed to show up the role of linear landscape spaces in the layout structure of a city. The current urban environment of existence of human shows a mix between nature, urbanized informative space, advanced innovative technologies, design elements. The authors accentuate importance of creation harmonious ecological and esthetically attractive environment of a city for human life and activities basing on the proper compatibility of these constituents. Basing on the selected methodology of research the authors analyze the available historiography material, world analogues of the investigated objects and their project conceptions. The article presents the existing theoretical conceptions of the urban development starting from the treatises of the ancient Greek philosophers up to project urban conceptions of the future cities basing on the linear landscape spaces. Position of the objects under research is outlined in the system of the green space. The system includes the objects under investigation as its integral part. The authors are educed the most widespread varieties of objects. The authors show the most widespread varieties of objects under research in the layout structure of modern cities. Particular attention of the authors is addressed to the linear parks, embankments, boulevards and parkways that play an important role in life and activity of a city and its habitants. Importance of proper implementation of project conceptions for such spaces has been shown by means of different spheres of design - landscape, ecological, ergonomics, urban and graphic.

The purpose of the article is to identify the main directions of improvement of the network of institutions of general secondary education in rural areas on the example of Ukraine. The authors developed an algorithm for research, consisting of four stages. During the study, the preconditions for forming a network of rural schools were considered. The following network parameters such as warehouse, spatial structure are found. Based on the analysis of modern socio-pedagogical requirements, the concept of promising organization of school services in rural areas has been developed. It is established that in conditions of rural settlements, it is advisable to form teams for teaching from pupils of different ages (multigrade classes). The authors provided suggestions on the formation of territorial educational districts as a promising direction for improving the network of rural schools. The perspective types of institutions of general secondary education, which are formed on the basis of interagency integration with other objects of cultural and household services of the population, are revealed. To improve the process of designing a network of village schools, the authors developed a methodology for optimizing the network of schools on the basis of linear programming.
