A Novel Approach towards designing highly secure Cryptography Encryption Algorithm

Authors: Neeraj Singh, Prof. Nitin Choudhary

Abstract- Information security is a progressing challenge for designers and programmers. To battle diverse assaults by programmers, there is a need for more reliable security innovations. In this research work a low complexity security algorithm is created. Utilizing different confounding variable elements is the quality of this calculation and makes retrieval of unique message by attacker more troublesome. I have first implemented DSEA [12] algorithm and found that the algorithm is easy to break or guess the keyword as there are only 26 different combinations of key is used. Then i implemented the algorithm which overcome the problem of DSEA [12] algorithm and also improve the outcomes. In this research I used 256 key combinations that make recovery of original message by attackers more difficult. All letters of key ought to be changed over into ASCII binary format keeping in mind the end goal to be utilized by security algorithm in the circular left rotation operation. The outcomes appear that our proposed security algorithm has less complexity as compare to Data Structure Encryption Algorithm based on circular queue to enhance data security (DSEA) (2018).

Keywords- Encryption, decryption, plain text, cipher text, symmetric key and Crytography.

Solar Photovoltaic Module Performance Characterization using Single Diode Modeling

Authors: Javed K. Sayyad, Paresh S. Nasikkar

Abstract—Solar photovoltaic (SPV) energy is most promising among all other renewable energy (RE) sources. Modeling of SPV module gives valuable results which will help to identify the behavior of SPV module in the normal operating condition. SPV module parameter is influenced by meteorological variables such as ambient temperature, incident solar radiation, wind velocity and humidity, etc. It will also help to calculate internal resistances and parasitics of SPV module. In this paper, the effect of variation in series and shunt resistance on the performance of SPV module is presented. Current–voltage (I–V) and powervoltage (P–V) curve are considered as the important performance measure for SPV module. The single diode model of SPV module having 36 SPV cells in series is simulated out through SPICE simulator. Simulation results show proximity to the labeled parameter at particular values of series and shunt resistance. This paper presents, derivation of the current equation for single and double diode model in simple steps. The dependency of electrical parameters (Im, Vm, Pm, F F, η) on series and shunt resistance variation is simulated, and the effects are discussed in detail.

Authors: Abouzar Sadeghzadeh, Dr. Maryam Haghshenas

Abstract- The internet has provided new opportunities for worldwide trade. Geographical limitations between buyers and sellers no longer exists and companies are conducting business, trade and communications using modern ways. This chapter will start by providing the payment methods and general infrastructure of well-established e-commerce systems. With the emergence of new opportunities, new limitations are also evident which will be referred to later on. Although e-commerce is extensively used in terms of trade, it has not yet its complete potential. The latter sections of the chapter will discuss proposals for different e-commerce aspects regarding worldwide promotion of the relevant sector.

Authors: Werneld Egno Ngongi, Du Jialu, Fortunata Kakwaya, Erick Phares Massami, Eliamin Kassembe

Abstract- This paper presents a design of ship dynamic positioning (DP) controller based on dynamic matrix predictive control (DMPC) technique. Rolling optimization and feedback correction approaches are used to design the controller. Through simulation studies and analysis of the dynamically positioned surface vessel, it can be proved that the controller can cause the ship’s position and heading converge to the desired predetermined values.

Keywords- Dynamic positioning, Dynamic matrix, Feedback correction, Predictive control, Performance index, Rolling optimization.

Hydrological Determination of Turbomachinery Potential in Current

Author: Levent Yilmaz

Abstract- Electrical energy production from ocean current needs more computational research where we can easily determine the capacity about wave currents by numerical analysis. This is the reason why we have compared different computational methods to have one similar methodology about the determination of process control. Extracting electrical energy from ocean currents could yield in excess of 10 TWh/year (0.4 EJ/year) if major estuaries with large tidal fluctuations could be tapped. Because the density of water is more than 830 times that of air, an ocean current of just 2.3 m/s can produce electricity at a rate equivalent to a mean annual wind speed of 62 m/s. The best sites in the world with currents about 10 m/s are located mainly off of the west coasts.

Spectrometric Determination of Selected Heavy Metals in Plant Tissues in Kisii County

Authors: Isaboke Peter Abel, Njagi Njomo, John Onam Onyatta

Abstract- Heavy metals are non-biodegradable and therefore they remain in ecological systems and in the food chain indefinitely, exposing top-level predators to very high levels of pollution. Elevated levels of heavy metals in natural environment may have a detrimental effect on both human health and the environment. Apart from the direct impact on health or environmental problems, water or soil contamination can cause considerable economic and financial damage. Plant samples were air dried and gently ground to pass through a 2 mm sieve and homogenized and stored for analysis. Statistical analysis was conducted on the data to determine the mean and Pearson correlation. According to the analysis of spectrometric technique, the concentrations of the heavy metals in the selected sites were below the recommended levels. The determination of levels of lead, zinc, manganese and cadmium in plant tissues in Kisii County were to be used to sensitize the general population of Kisii County on heavy metal health effects and the importance of environmental conservation. The study was also to inform the authorities in environment management on the level of heavy metal pollution in the County hence providing a reference for future studies on the same.

Tools for Evaluating Service Value

Authors: A. S. White, M. Censlive, D Nielsen

Abstract- This paper describes the development of useful tools to assist managers and engineers to choose between guiding parameters that are either numeric or subjective or both with equal emphasis. Such a procedure can produce a decision support process for service design or product design. The technique uses Dimensional Analysis (DA) that is rarely, if ever, used in service science with the method applied to two examples; a wheelchair-mounted robotic feeding arm’s computer interface, with choices in data input methods developed via collaboration, (co-creation) with its intended users and to the analysis of a Which™ evaluation for choice of best value cookers, both can be implemented with a spreadsheet.

Keywords- subjective decisions, co-creation; value; service dominated logic; dimensional analysis

The Indentification of Indicators in Tolerance of Biotic Stres Durability Determination in Maize Plant

Authors: Ali Beyhan Uçak, M. Cüneyt Bağdatlı

Abstract- This study was conducted to determine the stress tolerance markers in the corn genotypes (31D24, ADASA16, P1429) with biotic strase (S. nonagrioides Lef.) Resistance determined. The study was carried out in open field conditions in Siirt Province in Southeast of Turkey trial sites in three replications in 2015 and 2016 years with randomized blocks divided plot design. The average number of holes per year (2 years) / 100 internodi (number of years) was determined in the 31D24 genotype and the lowest P1429 genotype. However, the longest tunnel length (cm) was detected at the P1429 genotype, the lowest 31D24 genotype. It was determined that the tunnels were opened and fed from the varieties having high number of holes / 100 internods (31D24), but they did not show feeding behavior and the tunnels with long tunnel length (P1429) had long tunnels in the body. The highest yield (1039.83 kg da-1) for two years was determined at 31D24 with low live larvae + pupa and low tunnel length. The lowest yield (1008.16 kg da-1) was determined in the P1429 genotype with high tunnel length and high viable larvae + pupa. As a result of the research, it can be suggested that the number of holes of genotypes / 100 internodi in biotic strase (S.nonagrioides Lef.) Endurance lines in corn genotype lines, the tunel length and the number of live larvae are used as biotic stress tolerance indicator.

The Degree of Saturation with phosphorus (PSI, Phosphorus Saturation Index) in soils of the Central Region of Córdoba (Argentina)

Authors: Rollán, Adriana Ana del Carmen, Bachmeier, Omar Antonio, Moreno, Mario Alejandro

Abstract- The objective of this work was to estimate the degree of saturation of P (PSI, phosphorus saturation index) of the soil from its maximum adsorption capacity and confirm its suitability as a predictor of potential loss of P. The maximum adsorption capacity of P (Qmax) obtained from of the Langmuir adsorption isotherm and the degree of saturation of soil P (PSI) using Qmax and extractable P (PBray). The PSI obtained were in a range between 12 to 39%. The high PSI values observed at a depth of 0 to 5 cm suggest that these soils are vulnerable to P loss and determine the need to evaluate the potential for soluble P losses in runoff and drainage waters.

Energy Saving Measures of Residential Buildings in North Africa: Review and Gap Analysis

Authors: Samah K. Alghoul, Khairy R. Agha, Abdullateef S. Zgalei, Elhadi I. Dekam

Abstract- A common style case study as a typical residential building in Libya is studied. Single and combined energy efficiency measures were applied. The base model consumes 163.6 kWh/m2/year, where the space cooling load is devoted to be 4 times heating load, with the priority is to insulate roofs than walls. Improving the envelope thermal behavior reduces the energy consumption by 14.0 %. Upgrading interior lights leads to an annual saving of 7.7 %. Water heating strongly shares in the presence of peak demands for 9 months. Considering solar water heaters, reduces the required annual demand by more than 12 %. Using Photovoltaic Solar Panels, reduces the annual consumption by 19.3 %. Combining these energy efficiency practices results in savings of more than 54%, corresponding to a total energy reduction of 88.4 kWh/m2/year. For saving of 54% in residential buildings will result in a reduction of 19% of the national demand.
