Authors: Sunandar Endang
Published: October 2019

The numerical method is a technique used to formulate mathematical problems so that they can be solved using ordinary arithmetic operations. In general, numerical methods are used to solve mathematical problems that cannot be solved by ordinary analytical methods. In the Numerical Method, we know two types of system equations, namely the Linear Equation System and the Non-Linear Equation System. Each system of equations has several methods. In the System, the Linear Equation between the methods is the Gauss Elimination method, the Gauss-Jordan Elimination method, the LU (Lower-Upper) Decomposition method. And for the Non-Linear Equation System between the methods is the Bisection method (Share-Two), Falsi Regula method, Newton Raphson method, Secant method, and Fix Iteration method. In this study, researchers are interested in comparing the two methods in the Non-Linear Equation System, namely the Bisection method and the Falsi Regula method. And this benchmarking process uses the Java programming language tool, this is to facilitate analysis of method completion algorithms, and monitoring in terms of execution time and output analysis. So that we can clearly know what differences occur between the two methods.

In July 2018, the bottom sublittoral taxocens of diatoms of Issyk-Kul Lake (Kyrgyzstan) were studied: composition, structure, diversity, equiability and vertical distribution of these characteristics in depth. It was considered not only the ratio between the abundance of species, but also the size-ecological groups of diatoms in the structure and composition of communities. At 9 stations in the western, northern, and northeastern parts of the lake, at depths of 8.4–558 m, a total of 155 taxa of diatoms were found, adapted to dwelling on the bottom (48–89 taxa per station, an average of 66.56). With increasing of the depth, a general decline in species wealth was noted. At a depth of 558 m, the number of species was 49 (48 per 145.5 m). The average qualitative similarity of communities made 60,11%, while the set of species from site to site did not varied extremely. The structural diversity of taxocenes was everywhere high (H` = 3.052–3.782, on average 3.473), and the role of dominants was rather weak (PIE = 0.898–0.966, on average 0.938). Amphora species dominated at almost all stations (at a depth of 8.4 m — Achnanthidium affine).

Cotton, popularly known as white gold, is the king of natural fiber and an important cash crop of Pakistan which earns foreign exchange up to 11.7% and 2.9% of GDP. The present study was carried out in cotton growing areas of four divisions of Punjab to determine the choice of cotton growers for the selection of pesticides for the management of whitefly. The data of hot spots of whitefly were recorded twice a week from April to October during 2015, 2016 and 2017 by using the standard pest scouting method. The study revealed that an increase of 16.09% hot spots of whitefly was detected in 2017 as compared to previous two consecutive years (2015 and 2016). Regarding farmers’ choice for selection of pesticides used to control whitefly, the farmers used Imidacloprid, Acetamiprid, Buprofezin, Clothinadin, Diafenthiuron, Flonicamid, Matrine, Pyriproxifen, Pymetrozine, Spirotetramat. The comparison of three years indicated that maximum farmers preferred to spray Pyriproxifen on the hot spots of cotton whitefly followed by Buprofezin, Acetamiprid and Diafenthiuronwhile Clothinadin and Matrine were used by the minimum numbers of farmers. The use of these insecticides by the farmers during the three years was non-significant. The farmers preferred these pesticides being of third generation, IGRs, Neonicotinoids, environment friendly to human health and safer to natural enemies of whitefly
Alternaria alternata and Alternaria sonchi: Two new records of fungal pathogens on Sonchus asper (annual sow thistle) in Pakistan
Authors: Akhtar Khalid Pervaiz
Published: October 2019

Sonchus asper (annual sow thistle) is an annual or winter annual herbaceous plant native to Europe. It has become a very aggressive invader in many regions of the world. In February 2013, S. asper plants grown in and around the chickpea and tomato fields at Nuclear Institute for Agriculture and Biology (NIAB), Faisalabad, Pakistan were found to be severely affected by a leaf blight disease. Initially the disease symptoms began as small, circular, dark, necrotic lesions usually on the older leaves. At later stage, these lesions enlarged rapidly up to 4-12 mm in diameter and when spotting was abundant the entire leaf turned yellow. However, in April 2013, S. asper plants grown in and around the tomato and wheat fields at NIAB, Faisalabad, Pakistan were found with different leaf blight symptoms. The leaf spots were initially small, epiphyllous, irregular, scattered to marginal and dark-brown. Later on these spots enlarged, became orbicular to irregular but often angular, with brown to cinereous necrotic centers and usually with a narrow dark margin. On the basis of symptoms, morphological and cultural characteristics of the isolated pathogen, the causal agent was identified as Alternaria alternata from February infected plants while it was identified as Alternaria sonchi from April infected plants and Koch’s postulates were fulfilled. This is the first report of Alternaria alternata and Alternaria sonchi from S. asper plants in Pakistan

Proper identification of wild mushrooms is important to study their biodiversity and ecological role. The discovery of new medicinal mushroom species will lead to their exploitation as an industry. No research work has been done about medicinal mushrooms in Murree hills in the past. Keeping in view the importance of Ganoderma species, the present studies were carried out to determine the distribution and prevalence of Ganoderma species in Murree hills on different host plants. In all, eight species of Ganoderma were identified from Murree hills of Pakistan. Cedrus deodara and Eucalyptus citriodora were found to be the most susceptible hosts of Ganoderma species. The identified species were Ganoderma praelongum, G. chalceum (Eucalyptus citriodora), G. applanatum (Abies pindro), G. curtisii, G. multicornum (Cedrus deodara) G. lipsiense (Acacia arabica), G. multiplicatum (Pinus logifolia) and G. boninense (Morus alba). These identified species were non-mushroom and belonged to Phylum Basidiomycota. Variations were observed among different morphological and cultural properties. The color of the pileus surface was found light to dark brown and one species showed white to creamish color. The maximum length and thickness of pileus was found to be 32 cm and 10 cm respectively. Majority of Ganoderma specimens were lateral, central, stipitate, dimidiate and sessile. Among cultural characteristics, colonies of the Ganoderma species possessed brown color and some were white to creamish. Colonies were circular and smooth to slimy. Most of the species produced the hyphal system trimetic which had the generative and sketal hyphae. Most spores were brown ellipsoid and oval shape. The maximum spore index was 2.5. Maximum tube size of 1 cm and minimum tube size 2 mm were recorded. Pale brown cystidia with thin walls were seen from the germinating cystidia

Published: October 2019

Okra is a valuable vegetable crop of Pakistan. It is predominantly hosted by pathogens that reduce its yield and quality. Among these yield reducing agents, root knot nematodes are very important due to their host rang. Chemical control for this important pathogen is expensive and causes pollution problems so the present study was planned to evaluate the level of resistance among different available varieties of okra against Meloidogyne incognita under field conditions. The selected field was already infested with M. incognita. Data were recorded on various plant growth parameters and nematode development parameters after sixty days. Results indicated that for various nematode populations and plant growth attributes all the cultivars significantly differed with the Sabzpari 2001 and Sabzpari X Ramakrishna having best performance on over all yield by showing moderately resistant response but no variety was resistant against M. incognita. On over all basis and yield attributes, it is recommended that Sabzpari 2001 and Sabzpari X Ramakrishna are moderately resistant to nematode infestation and should be recommended to farmers in root knot nematode infested soils of Pakistan

Active control of compressor noise in the machinery room of refrigerators
Authors: Ku J. M. , Jeong W. B. , Hong C.
Published: October 2019

The low-frequency noise generated by the vibration of the compressor in the machinery room of refrigerators is considered as annoying sound. Active noise control is used to reduce this noise without any change in the design of the compressor in the machinery room. In configuring the
control system, various signals are measured and analyzed to select the reference signal that best represents the compressor noise. As the space inside the machinery room is small, the size of a speaker is limited, and the magnitude of the controller transfer function is designed to be small
at low frequencies, the controller uses FIR filter structure converged by the FxLMS algorithm using the pre-measured time signal. To manage the convergence speed for each frequency, the frequency-weighting function is applied to FxLMS algorithm. A series of measurements are performed to design
the controller and to evaluate the control performance. After the control, the sound power transmitted by the refrigerator is reduced by 9 dB at the first dominant frequency (408 Hz in this case) and 3 dB at the second dominant frequency (459 Hz here), and the overall sound power decreases
by 2.6 dB. Through this study, an active control system for the noise generated by refrigerator compressors is established.

Published: October 2019

Exhaust system noise is a major noise source of diesel tractor engines. In this article, this problem is improved by using bionics to alter the noise transmission route. By imitating the unique microstructures of owls, goshawks and sharks, the noise reduction effect was studied by designing
bionic surface textures for the inner walls of exhaust tailpipes through bionic modification. Different shapes of textures (rectangle, sine, diamond, triangle, inverted triangle, and a combination of all 5 different shapes) with heights of 1.5 mm were designed for application on the inner
walls of the exhaust tailpipes. Under the premise of not changing the structure and arrangement of the entire exhaust tailpipe system, bionic nonsmoothing and basic acoustic theories were used in 3D modeling, mesh discretization and acoustic simulation for each convex texture. The noise reduction
effects on different tractor bionic exhaust tailpipes were studied while utilizing identical convex texture heights, and the convex texture with the best noise reduction effect was identified.

Lean swirl combustion is the leading burner concept today, used in several steadyoperating applications to ensure awide operating range and low pollutant emissions. Approaching lean blowout is highly desired by design to achieve the lowest possible NOX emission. It was shown earlier
that quarls could significantly extend the operating regime of liquid-fueled swirl burners. In the present study, the accompanying acoustic noise is evaluated by continuous wavelet transformation to show the effect of various quarl geometries on lean flame blowout. However, the desired flame
shape of swirl burners is V, first, and a straight flame, and then a transitory regime can be observed before the developed V-shaped flame through increasing the swirl number. If the axial thrust is excessive, blowout might occur in earlier stages. Presently, the characteristic bands before
blowout were analyzed and evaluated at various quarl geometries, swirl numbers, and atomizing pressures. The latter parameter also acts as an axial thrust control to adjust the swirl number. firstly, a straight flame, then a transitory regime can be observed before the developed V-shaped flame

The article provides an analysis of the energy balance of a power plant in connection with the need to minimize the cost of fuel and electricity for heat supply. New analytical expressions comprehensively characterizing the efficiency of a power plant are developed. The analytical assessment of the impact of energy costs for the boiler needs on the energy balance of thermal power plant is made; methods for constructing schemes of the energy balance of thermal power plant and assessment of fuel efficiency in the boiler are designed. Attention is paid to errors arising from the use of the calculated values of air suction in the gas path of the boiler, and not the actual ones. Therefore, it is proposed to change the method of measuring heat loss with flue gases in order to eliminate or reduce the effect of air suction on the measurement results, taking into account the part of the flue gas heat received by the air in the air heater and returned to the boiler through the burner. The methods increasing accuracy of calculations of energy efficiency of the technological processes which are key in the centralized heat supply of the cities and settlements are developed.

The architecture of Soviet modernism occupies an important place in the history of world architecture. Due to the relatively recent recognition of Soviet modernism as a separate architectural trend, in most regions of our country (including the South of Russia), the objects, which were implemented in the Soviet Union in the 1960s and 1980s, have not been studied. This can lead to irreparable loss of structures with compositional and artistic value. The building of the former Museum of International Friendship, located in the park named after Pleven in Rostov-on-Don, is one of such objects. The building is designed using the basic planning, artistic and urban planning techniques of Soviet modernism. The article discusses the features of the Museum from different points of view. The retrospective analysis of transformations of the town-planning situation, which has influenced formation of the volume and compositional decision of the building, is carried out. The architectural and artistic features of the Museum are determined on the basis of field research and the study of preserved historical graphic materials. The article reveals the value of the object as a structure reflecting the main trends of Soviet architecture of the 1960s-1980s. The modern state of the building of the former Museum is investigated, the lost features of architectural and town-planning decisions are fixed. The necessity of restoration and preservation of its original appearance is confirmed

The article describes the importance of coloristics. Color is an integral part that forms a complete image of the world. It can unite urban ensembles, to bear the emotional and aesthetic burden. Color fills the world with expressiveness. The various functions of light in a person's life help to reveal the concepts of a color phenomenon, which contains a mixture of colors, the theory of color harmonies, manifested in the spiritual and material qualities of being. The color phenomenon is association formed in the consciousness. An important aspect in the formation of architectural space is the color of the object-spatial environment. This is a system that includes the color environment of natural objects and the human made architecture. Creative experience and scientific research in the field of color solutions are used for the successful design of the subject-spatial environment. In architecture, color is manifested in terms of aesthetic and psychological approaches. Any activity to create color solutions of the architectural space aims to meet the aesthetic requirements. In addition, coloristics must consider the function of objects, their design and features of the object concept in order to solve a wide range of issues.

Currently, much attention is paid to improving the technology of rubbers obtained by emulsion polymerization. The stage of isolation of rubber from latex is one of the problematic stages of this production. The development of more advanced coagulating systems remains relevant. For the first time, the possibility of using d-metal salts of the fourth period of the periodic table of Mendeleev’s salts as coagulants in rubber isolation is considered: chloride of zinc, nickel and cobalt. The influence of the consumption of these salts on the completeness of rubber isolation is investigated, the properties of rubbers are estimated. It is found that zinc chloride has the best coagulating ability. The formation of insoluble complex compounds between the coagulating agent and surfactants of the latex system is established. It is revealed that the acidification of the coagulating system leads to the release of higher carboxylic acids in free form and the formation of sulfuric salts of zinc, cobalt and nickel, which remain in the aqueous phase (serum). The presence of these salts in the serum allows its usage in the technological process of emulsion rubbers production for the preparation of aqueous solutions of chlorides of these salts, as well as acidifying agent (sulfuric acid). The positive outcome of the considered issues contributes to the solution of a number of environmental problems. The studied rubber mixtures and vulcanizates prepared on the basis of experimental rubbers meet the regulatory requirements.

This article describes the task of predicting roughness when finishing milling using neural network modeling. As a basis for the creation and training of an artificial neural network, a progressive formu-la for determining the roughness during finishing milling is chosen. The thermoEMF of the processing and processed materials is used as one of the parameters for calculating the roughness. The use of thermoEMF allows to take into account the material of the workpiece and the cutting tool, which af-fects the accuracy of the results. A training sample is created with data for five inputs and one output. The architecture, features and network learning algorithm are described. A neural network that de-termines the roughness for finishing milling has been created and configured. The process of learning and debugging of the neural network by means of graphs is clearly displayed. The network operability is checked on the test data, which allows obtaining positive results.

The mechanisms with asymmetric vibrations is the priority direction of development and creation of vibration devices for technological processes in the coming years. Mechanisms with asymmetric vibrations are constructively created on the basis of vibrators with directional vibrations in the form of steps, which differ from each other in the mass of unbalances, the radius of displacement of the center of mass from the axis of rotation and the frequency of rotation of the unbalanced shaft. The simplest device with asymmetric oscillations is a two-stage mechanism. Optimization of parameters of vibrators of each stage can be carried out according to the coefficient of dynamism of the oscillatory system. Rational parameters of the mechanism are consistent with the highest value of the coefficient of dynamism of the system. Currently, there is no method of design calculation for the translation of circular, elliptical and equally directed oscillations into asymmetric ones. The article presents the method of calculation associated with the translation of the parameters of vibration devices with circular, elliptical and equally directed vibrations into asymmetric ones with the highest coefficient of dynamism.

Osteoarthritis (OA) is one of the most common joint disorder which is debility seen in elderly & overweight people which affects the cartilage of bone joints like knee, feet, hip, and spine. In OA usually, cartilage is ruptured due to the kneading of bones with each other which will end up causing severe pain. In this condition, it is necessary to analyze the severity of OA which involves various medical imaging and clinical examination techniques. In this paper, automated analysis and detection of OA are proposed by calculating the thickness of cartilage which also helps to effectively detect and analyze the abnormalities in bone structures. Where we have considered various knee X-ray images. Initially, preprocessing and noise removal is performed. Further by implementing Particle Swarm Optimization (PSO) segmentation and thresholding, the specified knee region is cropped and analyzed to calculate the thickness of cartilage to detect the presence of OA.
