Multidimensional Systolic Arrays of LMS AlgorithmAdaptive (FIR) Digital Filters

A multidimensional systolic arrays realization of LMS algorithm by a method of mapping regular algorithm onto processor array, are designed. They are based on appropriately selected 1-D systolic array filter that depends on the inner product sum systolic implementation. Various arrays may be derived that exhibit a regular arrangement of the cells (processors) and local interconnection pattern, which are important for VLSI implementation. It reduces latency time and increases the throughput rate in comparison to classical 1-D systolic arrays. The 3-D multilayered array consists of 2-D layers, which are connected with each other only by edges. Such arrays for LMS-based adaptive (FIR) filter may be opposed the fundamental requirements of fast convergence rate in most adaptive filter applications

Towards sustainable cities: E-waste Collecting Machine: A Conceptual Design

Continuous development, keeping up with technology and increasing the production of multi-feature electronic devices are all factors that have increased the use of electronic devices all over the world. The accumulation of E-devices by individuals increases the amount of electronic waste that causes environmental pollution problems. Therefore, an innovative solution must be found that encourages people to give up old or damaged electronic items for recycling and benefit from their contents. An electronic waste collecting scheme that grants reward points to contributors and link the waste to recycling companies is suggested as an appropriate solution to attract people\u27s attention. The design of the electronic waste (E-waste) collecting machine and developing a business model are the main aims of this project, where spreading such innovative projects in the country will further spread the idea of sustainability, preserve the environment, and reduce pollution resulting from the accumulation of electronic waste

Fractal Image Compression Using Modified Operator (IFS)

Image data Compression based on fractal theory is fundamentally dierent from conventional compression methods, its idea is to generate a contraction operator whose fixed point approximates the original image in a complete metric space of images. The specication of such operator can be stored as the fractal code for the original image. The contraction mapping principle implies that the iteration of the stored operator starting from arbitrary initial image will recover its xed point which is an approximation for the original image. This Contraction mapping is usually constructed using the partitioned IFS(PIFS) technique which relies on the assertion that parts of the image resemble other parts of the same image. It then, nds the fractal code for each part by searching for another larger similar part. This high costly search makes fractal image compression dicult to be implemented in practice, even it has the advantages of a high compression ratio, a low loss ratio, and the resolution independence of the compression rate. In this paper, we investigate fractal image compression(FIC) using Iterated Function Systems(IFS). After reviewing the standard scheme, we state a mathematical formulation for the practical aspect. We then propose a modied IFS that relies on the fact  that, there are very smooth parts in certain images. From the view point of mathematics, we present the modied operator, proving its properties that make it not only a fractal operator but also more eective than the standard one. The experimental results are presented and the performance of the proposed algorithm is discussed

Epidemiological Study on Rift Valley Fever Virus among Domestic Animals in Taiz Governorate (Yemen)

Rift Valley Fever Virus (RVFV) is the causative agent of Rift Valley Fever (RVF), transmitted either by hematophagous insects that infect animals and humans or by direct contact with infected animals. This study was performed to preparing RVF antigen from liver of infected lamb to be used in detecting anti-RVFV antibodies by using Enzyme Linked immunosorbent assay (ELISA) and to study epidemiological prevalence of anti-RVFV IgM and IgG antibodies among animals which conducted in the Researches Center of Taiz University and Central Health Laboratory, Taiz Governorate, Southwestern Yemen. RVFV antigen was successfully prepared at a titer dilution of 1: 3200 by Chessboard (CB) ELISA assay. However, out of 188 samples, 147 samples were positive for ELISA assay, of which 12 (8.2 %) were positive for anti-RVFV IgM and 135 (91.8 %) for anti-IgG antibodies. The antigen was successfully produced, and successfully adhered to ELISA plates. Simple and inexpensive methods give good results. The results can be used to develop and refine predictive database for RVF transmission based on environmental and remote sensing data

SEROPREVALENCE OF DENGUE FEVER VIRUS AMONG SUSPECTED PATIENTS IN TAIZ GOVERNORATE-YEMEN

Background: Dengue Fever virus (DENV) considers one of the most important mosquito-borne viral diseases in the world and it is endemic in more than 100 countries. Objective: This study aimed to determine the seroprevalence of DENV infection among suspected patients and to investigate some associated risk factors with dengue fever infection in Taiz governorate, Yemen. Methods: This study was cross-sectional, descriptive, and experimental, combining the use of a structured questionnaire and analysis of serum samples obtained from 300 suspected patients attending at many hospital and clinic centers in Taiz during the period from July to November 2016. The serum samples were tested for anti-dengue immunoglobulin (IgM) and (IgG) by Enzyme-linked Immunosorbent Assay (ELIZA). Results: Out of 300 suspected febrile cases, it was found that 49(16.3%), 68(22.7%), and 17(5.7%) cases were showed positive for the IgM, IgG, and both IgM and IgG antibodies, respectively, while 166 (55.3%) cases were negative. The incidence rate was more in males than in females. The most affected age group with dengue fever infection were (21–30) years. Dengue Fever was more frequent among patients coming from the urban area, having secondary school, and low-income status people. Also, there was statistical significant between DENV infections with a place of residencyand gender (P<0.05) and not-statistical significance between DENV infections and other factors (P>0.05). Conclusion: Taiz governorate become one of the endemic governorates in Yemen particularly the Taiz city which should be brought to the attention of public health authorities.                       Peer Review History: Received: 5 September 2020; Revised: 15 October; Accepted: 26 October, Available online: 15 November 2020 Academic Editor: Prof. Kumud Upadhyaya, Kumaon University, Nainital, UK, India, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
