The Black-Scholes model known as standard model to price European option based on the assumption that underlying asset prices dynamic follows that log returns of asset is normally distributed. In this paper, we introduce a new stochastic process called levy process for pricing options. In this paper, we use the quadrature method to solve a numerical example for pricing options in the Indian context. The illustrations used in this paper for pricing the European style option.&nbsp; We also try to develop the pricing formula for European put option by using put-call parity and check its relevancy on actual market data and observe some underlying phenomenon.</p> Akash Singh, Ravi Gor Gor, Rinku Patel Copyright (c) 2020 Akash Singh, Ravi Gor Gor, Rinku Patel Wed, 23 Sep 2020 06:49:40 +0000 SEISMIC UPGRADATION OF TALL BUILDINGS <p>High rises have involved interest for engineers for as long as century. All the more along these lines, the previous thirty years have seen various structures ascending starting from the earliest stage, resisting gravity. Burj Khalifa Dubai, Taipei, Petronas twin pinnacle, Empire state building are a portion of the living instances of designing wonders.</p> <p>What befalls a structure when it arrives at such inconceivable statures separated from the awe that it will be, it additionally represents a gigantic measure of challenge for the auxiliary architect. Since then these structures are looked by administration stacking conditions. Two destroying powers of nature, wind and seismic tremor become truly basic for these structures. The harmony among firmness and pliability to be given turns into the controlling components to the plan of such structures. Routinely giving enough firmness against colossal burdens doesn't appear to fulfill the necessities. These structures are frequently given adequate pliability so as to disperse the gigantic measure of powers. In any case, there is a limit, with respect to how much malleability can be given in a structure. A fast figuring shows that the highest-level uprooting that can be securely borne by a 500 m tall structure is nearly 2m. The structure would not fall flat if its popular narrative dislodges by 2m.</p> <p>&nbsp;Use of different sorts of dampers and isolators have been utilized in disseminating this vitality. Much exploration has gone into advancement of TMDs, ATMDs, BTMDs, and seismic base isolators. Examination has additionally gone into different kind of investigations method as more vigorous powerful examination, weakling investigation, time history investigation and execution-based investigation.</p> <p>Here an endeavor has been made to explore the near benefits and negative marks of various sorts of auxiliary arrangements to comprehend their conduct under seismic and wind loads. The structure considered is of 50 stories. Different designs that have been considered incorporates propped frameworks, shear divider frameworks, dampers and isolators. The investigations results have been organized and plotted to comprehend their conduct. Time history examination and execution-based investigation by sucker investigation have additionally been concentrated to comprehend the conduct of structures.</p> MIRZA AAMIR BAIG, Tanveer Sultan Bhat Copyright (c) 2020 MIRZA AAMIR BAIG, Tanveer Sultan Bhat Wed, 23 Sep 2020 08:09:38 +0000 IN-PLACE ANALYSIS OF OFFSHORE JACKET PLATFORM FOR DIFFERENT WAVE DIRECTIONS <p>Offshore jacket platforms are subjected to variety of forces during their life period. To resists all kinds of forces, the structural elements should be designed properly to have safety and economy. In order to fulfil this purpose, the structure should be analyzed with great care.</p> <p>As the improvement of oil and gas moves into more profound water, in any case, taller stages with longer periods are fabricated that react all the more powerfully to extraordinary waves. Expectation of the dynamic reaction of such structures in extraordinary ocean states is in this way an essential plan thought. Standard waves have all their vitality lumped at a couple of particular frequencies and can, in this manner, cause wrong powerful enhancements, particularly if these frequencies happen to be near the regular frequencies of the structure. In any case, waves in the ocean are exceptionally sporadic and can be best depicted as directional range, which indicates the appropriation of wave vitality as for recurrence and heading, and is most appropriate for the examination of structure in recurrence space technique. For this situation the nonlinear drag is linearized and utilized in the Morison's condition. This guess is proper for the littler, operational sort waves considered in weariness counts, in light of the fact that the powers because of these waves are overwhelmed by the direct idleness part. Various kinds of investigations related with the coat stage ought to be performed to figure the reaction of the structure and measurement the components of the structure. Here an endeavor has been made to complete various examinations to comprehend the dynamic conduct of coat stages subject to different stacking conditions in various ecological conditions. Coat set up investigation was performed, both static and dynamic hypothetically fixed base stage.</p> <p>With the ongoing imaginative thoughts of investigation utilizing programming, it is presently simpler for the seaward architects to do disentangled and sensible assessment of the static operational and extreme point of confinement state qualities of format or coat stages, which are exposed to different ecological conditions. The essential auxiliary parts of coat type seaward structures including topsides, coat, heaps and the encompassing soil are viewed as utilizing SACS programming various types of investigations identified with coat stage according to API code prerequisite.</p> MIRZA AAMIR BAIG, UMER MAQBOOL Copyright (c) 2020 MIRZA AAMIR BAIG, UMER MAQBOOL Wed, 23 Sep 2020 09:12:44 +0000 EFFECT OF SHEAR WALL ON PERFORMANCE OF MULTISTOREY BUILDING <p>Seismic force, predominantly being an inertia force depends on the mass of the structure. As the mass of the structure increases the seismic forces also increase causing the requirement of even heavier sections to counter that heavy forces. And these heavy sections further increase the mass of the structure leading to even heavier seismic forces. Structural designers are met with huge challenge to balance these contradictory physical phenomena to make the structure safe. The structure no more can afford to be rigid.</p> <p>This introduces the concept of ductility. The structures are made ductile, allowing it yield in order to dissipate the seismic forces. A framed structure can be easily made ductile by properly detailing of the reinforcement. But again, as the building height goes beyond a certain limit, these framed structure sections (columns) gets larger and larger to the extent that they are no more practically feasible in a structure. There comes the role of shear walls. Shear walls provide ample amount of stiffness to the building frame resisting loads through in plane bending. But they inherently make the structure stiffer. So, there must be a balance between the amount of shear walls and frame elements present in a structure for safe and economic design of high-rise structures.</p> <p>Here an attempt has been made to study the behavior of different structures of reinforced concrete with different heights with and without shear walls. Coupled shear walls have also been studied to understand the comparative merit or demerit of framed structures with shear wall structures. Studies have been carried out on sample model structures and analysis has been carried out by ETABS software. It has been ensured to consider sample models that represent the current practices in structural design to include different structural configurations. Models having varied structural configurations like framed, shear wall, coupled shear wall, central core shear wall, core in core etc. have been taken into consideration. The inherent asymmetry present in the structures have also been dealt.</p> <p>The results have been tabulated and plotted to study their comparative behavior and interaction with each other. The findings of the study have been summarized and discussed.</p> MIRZA AAMIR BAIG, Rizwan Rashid Copyright (c) 2020 MIRZA AAMIR BAIG Mon, 28 Sep 2020 05:18:42 +0000 ARTIFICIAL NEURAL NETWORK WITH EXPERIMENTAL DESIGN: A FAST TOOL FOR RISK ANALYSIS AND FORECASTING IN AN OIL RESERVOIR, A CASE STUDY <p>Running simulation models is CPU intensive. In computing expensive tasks such as parameter screening, sensitivity and risk analysis (uncertainty analysis) and production optimization, it can be useful to establish a simple surrogate model (proxy model) that mimics the simulation model with regard to a specific target value (for example, total production) in order to reduce the computing time and to study the available uncertainties in the reservoir and their impacts on production.</p> <p>Artificial Neural Networks (ANN) are one of the main tools used in machine learning. The quality of the ANN as a proxy model is dependent on how the experiments that were used to make and train it are designed. In particular, it is crucial to understand the input parameters such that their respective dependencies, correlations, and ranges are incorporated in the modelling. A combination of simulation runs should be set up that can be used to train the ANN. This task is usually referred to as the design of experiments (DOE) which gives the most informative data sets to train ANN.</p> <p>In this study DOE was used to train the ANN in an oil reservoir under gas injection scenario and the trained ANN, in turn, was applied to create the production profiles which were further used for risk analysis.</p> <p>The accuracy of the results obtained in this study indicates that ANN as a proxy model combined with DOE as a sampling method for training purpose is a fast and reliable tool that can replace the simulator. This dynamic proxy model can be used for risk analysis, production optimization and production forecasting of oil reservoirs under Enhanced Oil Recovery (EOR) methods.</p> Nasser Alizadeh Tabrizi Copyright (c) 2020 Nasser Alizadeh Tabrizi Mon, 28 Sep 2020 07:17:32 +0000 COVID-19: IMPACT OF THE PANDEMIC ON THE SUSTAINABLE DEVELOPMENT GOALS <p>In this article, we are interested in what extent and how the COVID-19 health crisis affects the goal of sustainable development.</p> <p>So, after defining the concept of sustainable development and its pillars, this article recommends evaluating the impact of the health crisis on the sustainability of development.</p> <p>And to answer this question, we chose a method that involves first reviewing the theoretical literature on the subject and then continuing to study the impact of COVID-19 on many sustainable development goals.</p> Ammar Samout, Boutheina Marnissi Copyright (c) 2020 Ammar Samout, Boutheina Marnissi Mon, 28 Sep 2020 09:24:01 +0000 COVID 19: THE IMPACT OF DEMAND, SUPPLY, AND LABOR <p>This study aims to determine the effect of 1) demand, 2) supply, 3) labor, 4) covid 19. The sampling in this research was conducted by using a incidental sampling method. Methods of data collection through questionnaires that have been distributed to 100 respondents who have met criteria. With multiple linear regression analysis, it shows that the demand, supply, labor both partial and simultaneous have significant effect on covid 19. It can be concluded that mitigation of demand, supply, labor towards covid 19. The results of t test showed that demand is approved and indicates demand has great impact on affecting the covid 19, supply is not approved and indicates supply has less impact on affecting the covid 19, labor is approved and indicates labor has great impact on affecting the covid 19. The results of f test showed that both of the independent variables are simultaneously affecting the covid 19.

Three watering frequencies (i.e. once daily; once every 2 days; once every 3 days) were applied for two soil types (Leaf mold soil and merchantable soil) for a period of 150 days. The differences in seed germination, seedling survival and seedling growth were monitored in all experimental units. A more regular watering frequency increases soil moisture, and vice versa. The results showed that watering frequency had significant effects on seed germination (p=0.008), number of plant leaves (p=0.05), with visible but statistically insignificant effects on mean plant height (p=0.19) and seedling survival (p=0.3) for two plant species. The total height of plant species also varied greatly within treatments. Positive correlations were recorded between germination rate with leaf number (r=0.79, p=0.0001); plant height with survival rate (r=0.65, p=0.001); plant height with leaf number (r=0.77, p=0.0001); survival rate with leaf number (r=0.66, p=0.0001) etc. Seed germination and aboveground heights of D. barbatus and L. cyrtobotrya decreased at the more regular watering frequency of once daily in both soils. On leaf mold soil, the total height and mean height of L. cyrtobotrya decreased with increased water stress at once every 3 days watering frequency. Also, the total height of D. barbatus decreased with increased water stress at once every 3 days watering frequency on this soil, even though its mean height did not decrease. In contrast on merchantable soil, the total height and mean height of L. cyrtobotrya increased with increased water stress at once every 3 days watering frequency, indicating that this plant is more resistant to stress on this soil. Whereas, the total height and mean height of D. barbatus decreased with increased water stress on this soil. On leaf mold soil, once every 2 days watering was the most suitable watering frequency for both species in terms of achieving best seed germination and seedling establishment. In contrast on merchantable soil, once every 3 days watering frequency was most suitable for L. cyrtobotrya, whereas both once every 2 days and once every 3 days watering frequencies were suitable for D. barbatus on this soil. The results suggest that using the required watering frequency and soil type is imperative to ensure sustainability in plant production and seedling establishment.</p> Ettagbor Hans Enukwa Copyright (c) 2020 Ettagbor Hans Enukwa Mon, 12 Oct 2020 08:44:38 +0000 FABRICATION AND TESTING OF A SEMI-MANUALLY OPERATED FISH SCALE REMOVER <p>Commercial fish scale removers are very expensive.&nbsp; This study was conducted in order to fabricate and test the performance of a low cost, stand-alone semi-manually operated fish scale remover.&nbsp; The randomized complete block design (RCBD) quasi-experiment was used to test the capacity and efficiency of the semi-manually operated fish scale remover.&nbsp; Three (3) different kinds of fish in Northern Samar (Bangus, Sagision and Kirawan) with three (3) different sizes of scales (Large, Medium and Small) were used in the testing of the fabricated fish scale remover at three (3) different speeds of the scaling drum (High, Medium and Low).&nbsp; The results revealed that the higher the speed of the scaling drum, the higher is the scaling capacity of the manually-operated fish scale remover.&nbsp; Likewise, the bigger the scales of fish being descaled, the higher is the scaling capacity of the manually-operated fish scale remover.&nbsp; The average scaling capacity of the fish scale remover is higher than the average scaling capacity of an experienced fish vendors for kirawan and sagision but is lower than that of the experienced fish vendors for bangus.&nbsp; On the other hand, the average scaling efficiencies of the machine for all the fish used in testing the machine were highest at medium speed setting of the scaling drum.&nbsp; The cost and return analysis on the operation of the semi-manually operated fish scale remover revealed that it will have an annual net income of P 48,724.37, a payback period of 50 days, and a rate of return of 3.82.&nbsp;&nbsp; The actual cost of constructing the semi-manually operated fish scale remover is <strong>₱ 12,756.00</strong>.</p> Michael Dave B.
