 Abstract

Cryptanalysis is the process of key recovery, or plaintext recovery without the knowledge of the key in Cryptology. It helps us to improve the Cryptographic system by finding any weak point and thus work on the algorithm to create a more secure secret code. In the process of Automated Cryptanalysis we decrypt the cipher text with many possible keys to obtain candidate plaintexts. The basic type of algorithm suitable for this process is a Brute Force attack. This attack is only feasible when key-space is searchable on computational resources available to an attacker. On the other hand, only the most complex algorithms achieve really high accuracy of the plaintext recognition. Nature-inspired algorithms are a set of optimized problem-solving Metaheuristic derived from natural processes that can be used for Automated Cryptanalysis. Genetic algorithm use a stochastic approach to find the best solution in the large search space of the problem. In our research work, we use Genetic algorithm to Cryptanalyze Vigenere and Columnar Transposition Ciphers. A comparision study between those two ciphers is made by testing the algorithm with various file sizes of encrypted plaintexts with two encryption algorithms and analyze which is more efficacy to Genetic algorithm.

 Abstract

Analysis the performance of the company requires a rational thinking throughout the information given by financial statements but also information provided by the stocks markets are very crucial as are displayed to the investors who want to invest or the existing ones who want to see how their company is doing comparing to the open market with competitors. Throughout, this research IHG and MLC Hotels were compared using Beta to evaluate the volatility of risk, finding shows that two companies are performing well in comparison with the hospitality industry except some volatility of return observed especially for MLC Hotel which means it is more risky than IHG Hotel.

 Abstract

Prostitution in most of country is illegal, however sex tourism is taking a large segment of the world tourism market.To assess the implication of negative impact of sex tourism in Mombasa/Kenya a well-known macroeconomics equations to measure real Gross Domestic Product/rGDP using expenditure approach was used. Findings show that the aggregate demand/local sex workers is increasing (people get a lot of money) as well the aggregate supplier/tourists it will never reach at the maximum exploitation.

 Abstract

One of the key factors in achieving the optimum drug concentration in the systemic circulation for the desired (expected) pharmacological response is solubility, the phenomenon of solute dissolving in solvent to produce a homogeneous system. The main issue in developing formulations for new chemical entities as well as for generic development is low water solubility. Over 40% of the NCEs (new chemical entities) created by the pharmaceutical sector are essentially water insoluble. A significant difficulty for formulation scientists is solubility. Any medicine that is to be absorbed must be present in solution at the absorption site. Particle size reduction, crystal engineering, salt creation, solid dispersion, use of surfactants, complexation, and other techniques are used to increase the solubility of poorly soluble pharmaceuticals. These techniques include physical and chemical drug changes as well as additional approaches. A sulfonyl urea known glimepiride is used to treat type II diabetes. The chemical name for glimepiride is C24H34N4O5S, and it has a molecular weight of around 490.617 g/mol. It falls under the Biopharmaceutical Classification System's Class II. It is hardly soluble in various organic solvents and buffers, but entirely insoluble in water and acidic solutions. It is taken orally, is soluble in Dimethyl Sulfoxide but insoluble in water, methanol, or methylene chloride (dichloromethane) (DMSO). Given this, many generic medication manufacturers are more likely to create bioequivalent oral drug formulations. The poor bioavailability of oral dose forms, however, presents the biggest design problem. Aqueous solubility, drug permeability, dissolving rate, first-pass metabolism, presystemic metabolism, and sensitivity to efflux mechanisms are some of the variables that affect oral bioavailability. Poor solubility and inadequate permeability are the two most common causes of low oral bioavailability.

 Abstract

Everyone needs some norms to lead his/her life because norms make our life and working style smooth. In education and especially in higher education, some norms play very important roles. These norms may be in different forms. One form is professional ethics. Professional ethics are soul of higher education. This research paper is focused on the role and importance of professional ethics in higher education. Quantitative methods of research have been applied for the research. This paper included a survey to know the different aspects of professional ethics in higher education. The population of the research is college/university teachers and student from Delhi and NCR. The sample size is 200. This research paper is useful for teachers, students in higher education and researchers.

 Abstract

The lichen Parmelia perlata, often called black stone flower or Chharila, is a member of the Parmeliaceae family. It is spreading over the steep region of the Himalaya and North East India, growing in between the rocks, tree trunks, and ground. The plant's exterior coat is greenish black and white, and the thallus, which can grow up to 15 cm in diameter, is only weakly attached to the substrate. Its smooth upper surface is orbicular greyish white, while the lower surface is backish brown and hairy. Usnic acid, lecaronic acid, salazinic acid, and atronin, among other unique chemical components discovered in the lichen, have been traditionally given for bronchitis, excessive salivation, vomiting, toothaches, boils, and other inflammations, Aside from these conditions, it has also been linked to seminal weakness, nocturnal emission, amenorrhea, leucorrhea, dyspepsia, calculi, blood and heart conditions, stomach problems, enlarged spleen, bleeding piles, scabies, leprosy, general aches, etc. It strengthens the urinary system and inhibits the development of calculi. The primary goal of the current manuscript is to discuss the pharmacognostic information and pharmacological activity of this lichen.

 Abstract

The framework utilizes public key cryptography to provide required security services to enable exchange of keying material, and information about security policy and cipher suites. As the internet has evolved from host-to-host communication to content distribution, data centric networking is poised to improve networking efficiency. As cloud computing the internet of thing, The fifth generation networking become popular, there is that data is to be distributed or some potentially untrusted middle boxes.

 Abstract

Numerical analysis of natural convection in open ended ended two dimensional axisymmetric vertical tube has been carried out for a wide temperature range to find out the relation between non-dimensionalized number. Walls are maintained at constant wall temperature due to which convective flows were analyzed by varying the wall temperature and aspect ratio of the tube. The simulation is carried for turbulence model of natural convection. It was found that there is no single non dimensional number on which the flow can dependent. Numerical analysis of two-dimensional natural convection in open ended vertical tube has been carried out for a wide range of heat generation rate to find out the appropriate non-dimensional numbers governing the process. Buoyancy induced flows in a tube with adiabatic wall boundary condition and uniform volumetric heat generation rate in fluids were analyzed by varying heat generation rate and the geometrical aspect ratio of the tubes with and without considering surface radiation. Curve fits have been provided for non-dimensionalized mass flow rate versus other relevant non-dimensional numbers based on heat generated and geometry of the tube. Non-dimensional correlation has been found out for natural convection flow in an open adiabatic tube with internal heat generation and neglecting surface radiation. One more non-dimensional correlation has been found out for natural convection flow in an open adiabatic tube with internal heat generation and considering surface radiation.
