Finger vein biometrics have gained a lot of attention in recent years because they offer the perfect balance of security and economic viability, with advantages such as being the least susceptible to identity theft because veins are present beneath the skin, being unaffected by ageing of the person, etc. All of these factors make it necessary to create functioning models to meet the ever-increasing need for security. The use of facial recognition and AI-based biometrics, particularly in law enforcement, has become a hot topic because of its inadvertent demographic bias. Biometric bias, on the other hand, has far-reaching consequences that extend into daily use cases. When an ATM transaction or an online banking transaction is compromised by a false positive or negative verification, fraudulent activity is made easier. The study in this research work focused on the difficulty of determining the veins of a fingertip. On two widely used and freely available datasets of finger veins, we applied deep convolutional neural network models to feature extraction. Finger vein recognition has gotten a lot of interest recently as a novel biometric technique. Finger vein recognition might benefit from applying deep learning, an end-to-end approach that has shown promising results in sectors like face recognition and target detection.

Topic of exhaustive study for about past decades has been carried out in machine imitation of human reading. a small number of investigates have been accepted on the detection of cursive font writing like Arabic texts for its individual challenge and difficulty .In this work, a novel technique for automatic Arabic font recognition is proposed to demonstrate an suitable recognition rate for multi fonts styles and multi sizes of Arabic word images.

The scheme can be classified into a number of steps. First, segmenting Arabic line into words depending on the vertical projection and dynamic threshold then we implicated each Arabic word as a class by ignoring segmenting the word into characters .Second ,normalizing step, the size of Arabic word images varies from each other .The system converts the images that contribution into a new size that is divisible by "N" without remainder, to decrease the difficulty of feature extraction and recognition of the system that may allow images from different resources, Third, feature extraction step which is based on apply the ratio of vertical sliding strips as a features. Finally, multi class support vector machine (one versus one technique)is used as a classifier .This method was estimated on off line printed fonts, five Arabic fonts, (Andalus, Arial, Simplified Arabic, Tahoma and Traditional Arabic) were used and the average recognition rate of all fonts was 95.744%.

Blocks and chains are the building blocks of the blockchain, which is a community network. Blocks and chains are two terms used to describe collections of data information. The most fundamental need for a blockchain is that these postings be connected by cryptography, which is the case here. Cryptography. the entries in each block are added to as the list grows. Although the concept of blockchain cryptography is difficult, we have made it easier for you to understand. Asymmetric-key cryptography and hash functions are used in blockchains. Hash functions provide participants with a complete image of the internet. The SHA-256 hashing algorithm is often used in blockchains. In Bitcoin, where addresses are tracked by public-private key pairs, blockchains are often used. The public key in blockchain cryptography is a person's address. All participants have access to the participant's public key. The private key is used to get access to the address database and to authorise activities using the address. To ensure the integrity of the blockchain ledger, encryption plays a key role. Each event on the blockchain is recorded using encrypted data. As long as each user has access to their cryptographic keys, they may buy or trade cryptocurrencies. The root hashes of all transactions are stored in blockchains via cryptographic hashing. If somebody attempts to tamper with any data upon that blockchain, the main hash will have a completely new hash. Root hash comparisons may be performed on any other system to check whether the data is safe.

Let be an associative algebra over a field F of any characteristic with involution * and let K=skew(A)={a in A|a*=-a} be its corresponding sub-algebra under the Lie product [a,b]=ab-ba for all a,b in A . If for some finite dimensional vector space over F and * is an adjoint involution with a symmetric non-alternating bilinear form on V , then * is said to be orthogonal. In this paper, Jordan-Lie inner ideals of the orthogonal Lie algebras were defined, considered, studied, and classified. Some examples and results were provided. It is proved that every Jordan-Lie inner ideals of the orthogonal Lie algebras is either eKe* or is a type one point space.

In this paper, we continue to study the properties of the relation with some type of open sets, and we introduce -continuous function, semi-continuous function, -continuous function, and -continuous function are studied and some of their characteristics are discussed. In this work, we need to introduce the concepts of function, especially the inverse function to find all continuous function, so we want to prove some examples, theorems, and observations of our subject with the help of new concepts for the alpha-open sets of sums to make it easier for us to find a relationship between these formulas as well as the converse relationship has been studied and explained with illustration many examples. Hence, reaching to get a relationship (continuous, -continuous, semi -continuous) function at new condition.

The aim of This work is to present new types of spaces, which are space and space, based on the definition of new types of open sets, which is the feebly open set. we study there the basic properties and also obtained the effects between space and space and with the known space and with closed and open sets.

called f-normal space, which we studied and identified some of its properties as well as relationships with other sets, and we obtained some results that show the relationship between sets using theories obtained using the set from Style (f-open)

This paper holds to establish a soft pre-compact map and to investigate its associations with soft pre-compact maps, almost soft pre-compact maps, A-almost soft compact maps, A*-almost soft compact maps, mildly soft semi-compact maps, M-mildly soft compact maps besides M*-mildly soft compact maps which are utilized from the relations between their spaces under some conditions or without conditions. Consequently, the composition factors of soft pre-compact maps with soft pre-compact maps, almost soft pre-compact maps, and mildly soft pre-compact maps, A-almost soft compact maps, M-mildly soft compact maps are studied based on the previous association between them. Many examples are given to explain the relationships between the topologies and relations of the soft set

Definition of bi-supra topological space via graph theory was introduced in this study. We also studied some concepts related of bi supra-topological space via graph theory. "At least many theorems were proofed as a characterization and some examples introduced to explain the subject".

The goal of this study is to investigate the effect of couple stress on Powell-Eyring fluid peristaltic transport in an inclined asymmetric channel using porous medium. Peristaltic motion of a magnetohydrodynamic Powell-Eyring fluid in inclined asymmetric channel with porous medium, medium is investigated in the present study. The modeling of mathematic is created in the presence of effect of couple stress, using constitutive equations following the Powell-Eyring fluid model. In flow analysis, assumptions such as long wave length approximation and low Reynolds number are utilized. Closed form formulas for the stream function and mechanical efficiency are created. On the channel walls, pressure rise per wave length has been calculated numerically. The effects of the Hartman number (Ha), Darcy number (Da), material fluid parameter (w), inclination of magnetic field (β), amplitude ratio (∅), The effects of the Couple Stress on axial velocity and entrapment are investigated in detail and graphically shown.
