Three coordinate systems are used in finite element analysis: the local coordinate system defines each element's properties, the global coordinate system defines points in the entire structure, and the natural coordinate system specifies points within an element using dimensionless numbers between -1 and 1 with the origin at the element's center.
Electrostatic Potential Models
The electrostatic potential is the energy of interaction
of a point positive charge (an electrophile) with the
nuclei and electrons of a molecule. Negative
electrostatic potentials indicate areas that are prone to
electrophilic attack. For example, a negative
electrostatic potential of benzene shows that
electrophilic attack should occur onto the p system,
while the corresponding electrostatic potential for
pyridine shows that an electrophile should attack the
nitrogen in the s plane.

Finding the maximum common substructure (MCS) among molecules has many applications in the field of cheminformatics. It can be used in automated reaction mapping and molecule alignment, and it is also a popular measure of similarity, just to name a few. However, the complexity of the problem makes finding the exact MCS of two molecules too time-consuming for most use cases. At ChemAxon, we employ approximation algorithms in MCS search, but building one which is both practically fast and accurate is still a challenge. To meet the increasing demands on effective MCS search, we have taken our previous approach and applied different heuristics to further improve its speed and accuracy. The results are very promising, both in large-scale tests involving thousands of different compounds, and in application-specific cases.
Topological Indices of Molecular Graphs Under Specific Chemical Reactionsijcoa
Molecular graph serves as a convenient model for any real or abstract chemical compound. A topological index is the graph invariant number calculated from the graph representing the molecule. The advantage of topological indices is that it may be used directly as simple numerical descriptors in QSPR/QSAR models. Most of the topological descriptors are based either on atom-atom connectivity or on topological distances. A chemical reaction can be represented as the transformation of the chemical (Molecular) graph representing the reaction's substrate into another chemical graph representing the product. The type of chemical reaction where two substrates combine to form a single product (combination reaction) motivated us to study the effect of topological indices when a bridge is introduced between the respective vertices (of degree i, i=1, 2, 3) of two copies of the same graph. The graph obtained in this manner may or may not exist in reality, but it is the interest of the chemist to check the stability of the so obtained structure of the product. In this paper we present an algorithm to calculate the distance matrix of the resultant graph obtained after each iteration and thereby tabulate various topological indices. We also give the explicit formula for calculating Wiener index of the graph representing the resulting product.
Dynamic Structural Optimization with Frequency ConstraintsIJMER
The present work introduces a new method of structural optimization based on frequency
constraints by using FEM in conjunction with Evolution optimization. First able as in any structure using
this type of optimization the structure is meshed by very small element and the Eigen value (natural
frequencies) of the whole structure is find. Then for each element removal the same eigenvalue analysis
is done and a new natural frequency is calculated and assigned to an element removed. The sensitivity of
structure to this removal of material for each element will be calculated. The question now what will do to
control the natural frequency of the structure based on this removal of each element alone. The answer for
this question and based upon the sensitivity value, all natural frequencies can be shift towards the
required value, this include increasing or decreasing the frequency value and also increasing or
decreasing the gap between any pair of natural frequencies.

In the field of proteomics because of more data is added, the computational methods need to be more
efficient. The part of molecular sequences is functionally more important to the molecule which is more
resistant to change. To ensure the reliability of sequence alignment, comparative approaches are used. The
problem of multiple sequence alignment is a proposition of evolutionary history. For each column in the
alignment, the explicit homologous correspondence of each individual sequence position is established. The
different pair-wise sequence alignment methods are elaborated in the present work. But these methods are
only used for aligning the limited number of sequences having small sequence length. For aligning
sequences based on the local alignment with consensus sequences, a new method is introduced. From NCBI
databank triticum wheat varieties are loaded. Phylogenetic trees are constructed for divided parts of
dataset. A single new tree is constructed from previous generated trees using advanced pruning technique.
Then, the closely related sequences are extracted by applying threshold conditions and by using shift
operations in the both directions optimal sequence alignment is obtained.

HMM’S INTERPOLATION OF PROTIENS FOR PROFILE ANALYSISijcseit
HMM has found its application in almost every field. Applying Hmm to biological sequences has its own
advantages. HMM’s being more systematic and specific, yield a result better than consensus techniques.
Profile HMMs use position specific scoring for the matching & substitution of a residue and for the
opening or extension of a gap. HMMs apply a statistical method to estimate the true frequency of a residue
at a given position in the alignment from its observed frequency while standard profiles use the observed
frequency itself to assign the score for that residue. This means that a profile HMM derived from only 10 to
20 aligned sequences can be of equivalent quality to a standard profile created from 40 to 50 aligned
sequences.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Three different coordinate systems are used in the finite element analysis
1) Local Co-ordinate system 2) Global Co-ordinate system
3) Natural Co-ordinate system
Local Co-ordinate System
When for each element in FEM, a separate coordinate system is used for deriving
element properties it is called as Local Co-ordinate system.

Global Co-ordinate System
The coordinate system is used to define the point in the entire structure is
called as Global Co-ordinate system.

4. Coordinate systems used in FEM
Natural Co-ordinate System:
Natural Co-ordinate System is a coordinate system which permits the
specification of a point within the element by a set of dimensionless numbers,
whose magnitude never exceeds unity.
• Maximum value of ordinate is +1 and Minimum is -1
• In this coordinate system, origin is always assumed at the center of element.
