Vein palm recognition model using fusion of features

One of the most promising mechanisms in the field of security and information safety is authentication based on palm vein. The main reasons that vein palm becomes an authentication method is because of its distinctive privacy, as it is difficult to manipulate or change its results, because of the location of the vein within the palm. With the use of this technology, it has become easy to maintain data from unauthorized access and unwanted persons. In this work proposed model are suggested that contain four stages to reach the results: in the first stage is the pre-processing stage where histogram equation was used to enhance the image and the properties are shown, the second stage is the extracting the properties where, Gabor filter and 2-discrete wavelet filters are suggested for features extraction, where it is considered one of the most important filters used to extract the features, as well as in the third stage "PCA" are used for data or features reduction, because of its advantages in analyzing the features and reducing the spacing between them. As for the last stage, the Euclidean distance used to measure the spacing. The results were acceptable and convincing, since the similarity ratio 96.2%. These results were obtained after several tests and using the Gabor filter with 2D-discrete wavelet transform and principal component analysis (PCA), I got the best results

Energy Efficient Routing Protocall By One Way Multi-Hope Sensor Nodes

Multi-hope is widely used for data aggregation and transmission in various applications. The resource availability determines the life time of a WSN. Sensor nodes are powered by a tiny battery that supplies the required energy for the sensor and transmitter. The residual energy available at any moment decides the fitness of the sensor node. The sensor node senses the environment and transmits the data to the sink. Efficient data transmission and aggregation with less energy consumption can prolong the lifetime of the sensor network. The sensor node that is inside the coverage area of the sink can directly transmit the data to sink in a single-hop transmission. The sensor node that is not inside the coverage area should transmit the data to the neighbor node which is in the coverage area of the sink. The data is then turn transmitted by the node close to it fall in multi-hop transmission involving a number of intermediate nodes to forward the data to the sink and consumes extra energy for the forwarding process. The formation clusters and data transmission of data by Cluster Heads (CH) can eliminate many nodes involved in the transmission of same data. Clusters are a group of self-organized nodes in a geographic location that can communicate among them. A node in a cluster with higher residual energy will be acting as CH and all other nodes in the cluster transmit the data to the CH. The CH transmits the aggregated data to the sink. The CH transmits the data to the sink either in single-hop transmission or multi-hop transmission. The cluster head consumes more energy than other nodes in the cluster as it is involved in aggregation and transmission process

The effects of using variable lengths for degraded signal acquisition in GPS receivers

The signal acquisition in GPS receivers is the first and very crucial process that may affect the overall performance of a navigation receiver. Acquisition program initiates a searching operation on received navigation signals to detect and identify the visible satellites. However, signal acquisition becomes a very challenging task in a degraded environment (i.e, dense urban) and the receiver may not be able to detect the satellites present in radio-vicinity, thus cannot estimate an accurate position solution. In such environments, satellite signals are attenuated and fluctuated due to fading introduced by Multipath and NLOS reception. To perform signal acquisition in such degraded environments, larger data accumulation can be effective in enhancing SNR, which tradeoff huge computational load, prolonged acquisition time and high cost of receiver. This paper highlights the effects of fading on satellite signal acquisition in GPS receiver through variable data lengths and SNR comparison, and then develops a statistical relationship between satellite visibility and SNR. Furthermore it also analyzes/investigates the tradeoff between computation load and signal data length

THE ETHICAL ANALYSIS OF ADAPTATION OF RANDOMIZED CONTROLLED TRIAL APPROACH IN THE FIELD OF IMPACT EVALUATION FOR HUMANITARIAN PROJECTS

Conducting and communicating research is a responsible intellectual job. A researcher would go analysing immense literature and would search for valid evidence. Prior to narrating an authentic statement. Correspondingly while selecting a method for study it is vital to opt for an approach that is ethically suitable in a defined context. While applied on a set of a populace, generally denoted to as a sample and/or universe. Therefore, social research would be a more laborious task. Hence, the social context is ever-changing in terms of time and space. Diverse methods of social research are being invented yearly. To compete with consistently changing social phenomena and needs of evidence. Operational research, evaluation, and screen monitoring are the most prominent approaches of modern social research. Hence, these naïve approaches of social research would undergo learning and adaptation. Community development projects and retrospective studies thereof are also being synthesized, with existing methods of social research. An identical practice is an adaptation of the Randomized Controlled Trial hereinafter (RCT) approach to conduct impact evaluations of humanitarian and development projects. Hitherto, RCT was being widely used by health researchers as a clinical research approach. Hence, an adaptation of this clinical research approach for field studies, particularly for the evaluation of humanitarian projects. Those are being implemented to provide survival support to vulnerable communities. It would require this approach to undergo some ethical adaptations. This research paper is developed to commence a wider literary discourse on requisite ethical adaptations for RCT to use in the evaluation of humanitarian projects. This research paper brings the findings from desk and field. To discuss key questions; where and how we can use RCT, and what ethical adaptations are necessary not to be forgone? This discourse is established on the usefulness of RCT, ethics of social research, ethics of evaluation, and humanitarian principles. The overarching purpose of this research paper is to facilitate the adaptation of RCT in the field of impact evaluation. While considering the ethical principles of the development sector and evaluation. Article visualizations

Impact of the COVID-19 Pandemic on the Prescribing Patterns of First-Line Antibiotics in English Primary Care:A Longitudinal Analysis of National Prescribing Dataset

The COVID-19 pandemic has impacted on public access to health services. This study aimed to investigate the impact of COVID-19 pandemic on commonly prescribed first-line antibiotics in English primary care. A secondary analysis of publicly available government data pertaining to primary care prescribing was conducted. A list of twenty first-line antibiotics used to treat common infections was developed following the National Institute of Clinical Excellence (NICE) guidelines. All primary care prescription and cost data pertaining to commonly prescribed first-line antibiotics in England between March and September of 2018–2020 were extracted and adjusted for inflation. Analysis suggests prescribing of antibiotics significantly reduced by 15.99% (p = 0.018) and 13.5% (p = 0.002) between March and September 2020 compared with same time period for 2018 and 2019, respectively. The most noticeable decrease in 2020 was noticed for prescribing for meningitis (−62.3%; p = 0.002) followed by respiratory tract infections (−39.13%; p = 0.035), in terms of indications. These results are suggestive of reduced transmission of infections in the community due to national lockdowns, social distancing and hygiene practices. In addition, the impact of reduced face-to-face consultations in general practices needs to be investigated as a potential reason for reduced prescribing. The pandemic also offers an opportunity to rationalize antibiotics use in the community

Fabrication of a new photo-sensitized solar cell using TiO2\ZnO Nanocomposite synthesized via a modified sol-gel Technique

The current research synthesized was carried out using a modified solgel Technique for titanium dioxide ( TiO2) and zinc oxide (ZnO) nanocomposite. The morphology and optical properties of the synthesized nanocomposite were examined using a transmission electron microscope ( TEM) and UV-Visible spectroscopy.

The product of TEM has proof of the inclusion in the ZnO matrix of spherical TiO2particles. Also found were TiO2 sections attached to the ZnO-like rodlike particles., the ZnO/TiO2 Nanocomposites had better optical absorbing properties. The nanocomposite has been used to create a new photosensitizer solar cell with the efficiency of energy conversion of approximately 4.6%, using (E)-ethyl 4- ((4-nitrobenzylidene)) aminobenzoate as organic photo-sensitized (OPS) by (ITO/TiO2\ZnO nanocomposite/POS/iodine/silver (Ag) nanofilm/ITO)

The Issues in Which Sibawayh Made a Mistake in the Book ``Ea'arab of the Qur'an'' for An-Nahas/A Grammar Study

This study sheds light on the issues in which Sibawayh made a mistake in the book ``Ea'arab of the Qur'an'' for An-Nahas, a grammatical study, where I enumerated these issues and edited them by presenting and discussing the evidence and then concluded them with the opinion of the researchers, with a clear statement of misleading. All this stems from justice and truth, far from fanaticism or inclination toward one scholar without another. The research was divided into an introduction and a preface that included a brief translation of Mark Al-Nahas and a definition of confusion both linguistically and idiomatically, then the issues that Al-Nahas made mistakes in Sibawayh and the issues in which other scholars were mistakenly transferred to Sibawayh. Finally, a conclusion that included the most important results extracted from the research and a list of the most essential approved sources. Keywords: Al-Nahas, Sibawayh, mistake, mubrad, Basroun, Kufi

Natural convection in a square inclined enclosure with vee-corrugated sidewalls subjected to constant flux heating from below

Two-dimensional steady natural convective flow in a square inclined enclosure with vertical vee-corrugated sidewalls and horizontal top and bottom surfaces has been numerically studied. A discrete heat flux strip of 24% of the total length is flush-mounted on the bottom wall, while the other non-heated parts of the bottom wall and the top wall are considered adiabatic. The two vee-corrugated sidewalls are maintained at constant cold temperature. Grashof number is varied from 103 to 106, corrugation frequency is varied from 0.5 to 2.0, corrugation amplitude has been fixed at 10% of the enclosure height and the enclosure inclination angle is varied to 0◦, 10◦, 20◦ and 30◦ respectively. The enclosure is filled with air (Pr = 0.71). The flow has been assumed to be steady and laminar. Fluid properties have been assumed constant except for the density change with temperature that gives rise to the buoyancy forces. The solution has been obtained using the governing equations written in terms of dimensionless variables. The dimensionless governing equations are solved using finite volume method. Results are presented in the form of streamline and isotherm plots. The results of the present work show that the natural convection phenomenon is greatly affected by increasing the enclosure inclination angle. The variation in the average Nusselt number at the bottom wall, where the heat source exists and the maximum dimensionless temperature are also presented. The results are compared and found to be in a good agreement with other published results
