A Sawtooth Shaped CPW Fed UWB Microstrip Patch Antenna for Biotelemetry Applications

Abstract: A novel and simple sawtooth shaped Ultra-Wide band (UWB) antenna design with coplanar waveguide feeding for biotelemetry applications have been suggested in this research. A unique model & noteworthy enactment of the proposed antenna validates its robustness among the other antenna of similar types. This antenna covers almost 83.7% of the UWB in between 3.1 to 10.6 GHz, having an impressive return loss below 13 dB throughout the whole range. There are four resonating frequencies within the range with a maximum return loss of 26.769 dB. Obtained maximum directivity and gain for the projected antenna are 7.635 dBi and 7.641 dBi respectively. The optimized dimension of the antenna with a simple structure of sawtooth shape is 49 mm ⨯ 42.5 mm ⨯ 1.64 mm which can be easily integrated with handheld devices for UWB applications. Several calculations and performance analysis have been done using Advanced Design System (ADS) to make the antenna more invigorated for practical use.

Parallel Data Transmission: A Proposed Multilayered Reference Model

Abstract: Data transmission process between host to host in the computer network follows a basic system namely OSI reference model In this model data processing starts at the application layer, breaks the data into segments at the transport layer and processing ends at the physical layer Afterwards it transfers segmented data between different layers, bit wise conversion taking place at the physical layer through the medium In this paper a new parallel data transmission process has been proposed In this research all segmented data broken in the transport layer at the same time, transfer through the medium There is an interrelationship between layers in the proposed model Moreover this system has both way data transmission capability Layers can inherit information from upper or lower section This leads the system to more dynamic that is evolutionary To support this type of data transmission process, a new reference model proposed in this research And thus the system model works faster and more error free than the existing data transmission system

Chapman-Kolmogorov Relation Based Median String Algorithm for DNA Consensus Classification

Abstract: Consensus string is the most frequent common pattern in a set of string. Consensus string is an important feature of DNA sequence. Many algorithm have been introduced to discover consensus string. Among them, median string algorithm is the most popular one. Basically, that is a brute force algorithm.DNA sequence is composed of a series of four letter alphabet ∑={a,c,g,t}. If the size of the consensus string is l, then the algorithm generates all the 4l number of l length strings called motifs or l-mer. Then try to fit the motifs one by one with the sequence. In this paper we have discovered a way to reduce the search space using chapman kolmogorov relation. We found that, the proposed system can find the same consensus string within a shorter period of time than the time taken by the median string algorithm. As the l-mer size increases, the proposed system takes much less time than the median string algorithm. For l-mer size 7, we found the proposed system is 47 times faster than the median string algorithm.

Disclosure of Financial Reporting of Islamic Financial Institutes of Bangladesh: A Concept of Relevant Reviews

Abstract: Islamic banking is a system of banking that avoids receipt and payment of interest in its transactions and conducts its operations in accordance with Shariah principles to achieve the objectives of Islamic economy. The main objective of this review paper is to compare the level of disclosure of information by the Islamic Banking sector in Bangladesh. Multiple linear regression techniques will be used to test the hypotheses under study. The findings of this review paper is the supervisory authorities should recognize the need to set up a regulatory framework that, while consistent with Islamic precepts, would be pragmatic and flexible enough to meet internationally-accepted prudential and supervisory requirements. Effective prudential supervision of Islamic Banks in their home countries is important to foster integration between Islamic and conventional banking systems.

A Comprehensive Drug Management System by Segregating Spurious and Substandard Drugs Using Blockchain Technology

Abstract: Nowadays, one of the most serious problem is spurious drugs in pharmacology. Some prominent research funding organizations stated that nearly ten to 30 percent of the medicines are fake in developing countries. This have now become a major worldwide problem. One of every ten medicines are either fake otherwise don’t follow standard of drugs in developing countries and making the situation worse there. It is very tough to standardize safety regulation of medicines because of the rise of internet pharmacies. Counterfeited drug passes through various distributed complex networks. So, it is hard to detect the counterfeited medicines. For distributed complex networks, the fake drugs get chance to get into the genuine drug supply chain. The security of the drug supply chain has become the utmost concern of public health sector. To get drug supply chain records which are secure, a drug management system is developed using Hyperledger Fabric Blockchain platform in this work. This developed system solves the problem by performing transactions of drug records on a blockchain platform to create a digital, smart drug supply chain. To limit the access to electronic drug records, a smart contract is launched. A flexible android application for manufacturers, distributors, pharmacies and consumers have been made to increase the traceability of the drug.
