TL;DR: Only an authorized person will be able to transmit and receive the data through optical link by using biometric at transmitter end and code lock at receiver end and hence secure transmission of data can be done.
Abstract: The rate of crime, intruders and vandals is increasing day by day and the security gadgets still need to be modified so that we can make the transmission of information more secure. To end this, we need to design a cheap and effective intelligent and advance security system which can use advance technologies like biometric, code lock and optical link for the safe and secure transmission of information. By this technique only an authorized person will be able to transmit and receive the data through optical link by using biometric at transmitter end and code lock at receiver end and hence secure transmission of data can be done.

TL;DR: This research paper is focusing on a secure communication where biometric system can be used as a good and effective security option and automation can be achieved at the receiver end from the transmitter end.
Abstract: With the explosion of information traffic due to the Internet, electronic commerce, computer networks, multimedia, voice, data, and video, the need for a transmission medium with the bandwidth capabilities for handling such vast amounts of information is paramount. Fiber optics, with its comparatively infinite bandwidth, has proven to be the solution. The security inherent in optical fiber systems is a major benefit. The increasing rate of crime, attacks by thieves, intruders and vandals, despite all forms of security gadgets and locks, still need the attention. To make optical link more secure many devices can be used for transmission and reception purpose. These devices may be DNA sensor lock, card sensor lock, electronic eye lock, thumbprint sensor lock and electronic combination lock. In this research paper we are focusing on a secure communication where biometric system can be used as a good and effective security option. An important and very reliable human identification method is fingerprint identification. As fingerprint of every person is unique thus it can be used in various security options. Fingerprint recognition at the transmitter side allows only valid person to transmit the signal. At the receiver side code lock security can be economic and good option to allow only valid user to receive the information which has been sent through secure optical link. During communication over the optical link, automation can also be achieved at the receiver end from the transmitter end. With the help of automation, energy consumption at the receiver end can be reduced upto a great extent from the transmitter end.

TL;DR: Sarma et al. as mentioned in this paper found that OMgp binds to the Nogo-66 Receptor 1 (NgR1) which in turn restricts the normal functioning of the central nervous system.
Abstract: The inability of neural cells to regenerate themselves after an injury represents the major difference between neural cells and other cells of the body. Various factors are responsible for this, as the expression of myelin-derived inhibitors of axonal outgrowth such as neurite outgrowth inhibitor (Nogo), myelin-associated growth factor, and oligodendrocyte-myelin glycoprotein (OMgp) hinder the central nervous system (CNS) axons to recover properly and inhibit the neuron regeneration. The patient with spinal cord injury can even permanently lose their function due to the inability of axons to regenerate. However, their role in neural regeneration in vivo is not known completely. During the study, we found that once CNS gets injured, the axon growth inhibitor OMgp binds to the Nogo-66 Receptor 1 (NgR1) which in turn restricts the normal functioning of CNS. Considering the OMgp as the target protein, two flavonoid libraries (curcumin and piperine) were screened against it to get potential inhibitors. The effectiveness of the ligands was first screened by three-tier structure-based virtual screening by Glide, Schrodinger. Based on the docking score, the best-docked compounds were taken for absorption, distribution, metabolism, and excretion analysis and the top two complexes from each library were chosen for simulation studies. Flavonoid ligands showed a much better binding affinity when compared with already known inhibitors Riluzole and Minocycline. To date, no natural inhibitors are known for OMgp. Hence, this study can provide novel insight for upcoming research in this area. Communicated by Ramaswamy H. Sarma.

TL;DR: This paper is a proposal to develop a project which is combination of two major security systems that are biometric security system and optical fiber link, which can provide security where secure communication is required such as bank, industry, college and election commission etc.
Abstract: Communication is an important part of our daily life. The communication process involves information generation, transmission, reception and interpretation. A technical overview of the emerging technologies of fiber optical communication and optical networking fiber optical communications has enabled much higher data rates. In present scenerio it is continuously being noticed that people are very concerned about privacy of their data. But some unauthorized persons, who are little bit advanced in technology, can access other’s data. So to provide security to the people for their data multiple security systems are being used in the present scenario like biometric which is well known for being used in the security purpose and second one is optical fiber link which is also used for the security purpose. Other security systems are code lock, RF-ID etc. So in present scenario the biggest problem is to provide security where secure communication is required such as bank, industry, college and election commission etc. This paper is a proposal to develop a project which is combination of two major security systems that are biometric security system and optical fiber link. Through this project analog and digital data can be transmitted using highly secured optical fiber link while having a biometric security to transmit the data at the transmitter end and having a code lock security for reception purpose at the receiver end. Through this project automation can also be done at the receiver end from the transmitter end.

TL;DR: In this article , three types of features of secondary components are extracted, i.e. invariant moments, DCT, and DFT, which are classified using the KNN classifier for recognition.
Abstract: Character recognition for the Urdu language is always a tedious task because of its complexity as Urdu words are composed of ligatures that further consist of primary and secondary components. The Secondary components further consist of Urdu diacritical marks which play an important role in recognition of the Urdu language. This paper presents the technique for recognizing these secondary components to improve the recognition accuracy of the Urdu language. For this, three types of features of secondary components are extracted i.e. invariant moments, DCT, and DFT. The trained data set consists of a total of 228 features out of which 28 are invariant moment features, 100 are DCT features and 100 are DFT features. These extracted features are classified using the KNN classifier for recognition. After extraction of variant and invariant features of characters, the KNN is evaluated with different threshold values. When the threshold value of KNN is considered as 1, then the KNN achieves 89.6% recognition rate for variants and invariants features. But, if the value of k is set to be 2 the recognition rate of KNN (97.57%) increases. Thus, the value of k improves the character recognition rate.
