Sudanese Vehicles License Plate Recognition

ABSTRACT Vehicle license plate recognition is a computer vision method that aims to automatically recognize the vehicle’s identification number from the vehicle image. Therefore, it is an important component for automating many control and surveillance systems, such as: road traffic monitoring, private and public entrances, highway electronic toll collection, red light violation enforcement, and theft control. Although, considerable researches have been carried out for vehicle license plate...

Study of the optical properties of aluminum doped Zinc Oxide using Ultra Violet characterization technique.

Abstract In this work, zinc oxide nano particles were synthesized by sol-gel method, from Zinc Acetate dehydrates (ZnC4H6O4). 2H2O, then the aluminum oxide was also prepared by sol-gel method from Aluminum acetate C6H9AlO6. Then ZnO was mixed by Al2O3 with concentration ratio of (0, 25, 50) % to get four samples of AZO, these samples were characterized with UV-VIS spectrometer, and the optical properties of AZO were studied. It is clearly seen that the energy gap decrease with increasing of ...

Geological Distribution Of Mineral Resources In Southwestern Nigeria

  ABSTRACT The occurrence and distribution of the resources of southwestern Nigeria are intimately associated with the geology of the area. The basement complex of southwestern Nigeria lies to the east of the West African Craton, an area that has undergone late Precambrian to early Palaeozoic orogenesis. To the east and south, the Mesozoic-Recent sediments of the Dahomey and Niger Coastal Basıns cover the Basement Complex, The mineral resources of southwestern Nigeria are grouped into thre...

Deformation Characteristics And Work-Hardening Behaviour Of Some High Strength Manganese Steels.

Abstract A Study Has Been Made On A New Type Of Wear Resistant/High Strength Iron-Manganse-Molybdenum Steel. This Study Includes The Influence Of Composition And Heat Treatment On The Mechanical Properties. The Exceptional Work-Hardening Rate Is Due To Strain-Induced Formation Of Lath Martensite Which Itself Also Takes Part In The Work-Hardening Process. The Influence Of Higher Molybdenum Contents Was Evident In Preventing Brittleness Of The Solution Treated Steels. An Optimum Composition Ran...

Deformation Characteristics And Work-Hardening Behaviour Of Some High Strength Manganese Steels

ABSTRACT A study has been made on a new type of wear resistant/high strength iron-manganse-molybdenum steel. This study includes the influence of composition and heat treatment on the mechanical properties. The exceptional work-hardening rate is due to strain-induced formation of lath martensite which itself also takes part in the work-hardening process. The influence of higher molybdenum contents was evident in preventing brittleness of the solution treated steels. An optimum composition ran...

Model For Improving Performance Of Network Intrusion Detection Based On Machine Learning Techniques

Digital crimes have increased in number and sophistication affecting the networks quality of services parameters like confidentiality, integrity and availability of resources. Network Intrusion Detection Systems (NIDS) are deployed to optimize detection and provide comprehensive view of intrusion activities. However, NIDSs generates large volumes of alerts mixed with false positives, and repeated warnings for the same attack, or alert notifications from erroneous activity. This prevents ...

A Model For Detecting Information Technology Infrastructure Policy Violations In A Cloud Environment

The pervasiveness of the internet and available connectivity solutions brought about by cloud computing has led to an unprecedented increase in technologies built based on information technology infrastructures. This has improved the number of cloud users and substantially increasing the number of incidents related to the security of infrastructure and data in the recent past. Most organizations consider the deployment of different types of protection systems to curb various malicious ac...

Investigating Selected Egocentric Users On Social Media Platforms Using Social Network Analysis In Mining Forensic Evidence For Law Enforcement In Kenya

Investigation of social media using social network theory is a new powerful tool that will aid and ease law enforcement agencies in multi-faceted ways in this ever evolving digital landscape. It is against this backdrop that this study focused on identifying and investigating selected individuals on Facebook and Twitter social media platforms. In particular, selected respondents from University of Eldoret, Kibabii, Moi, Kisii and Rongo Universities were involved in the study. The objecti...

Effect Of Change Of Aluminum Nanosize In Its Paramagnetic Permeability

Abstract A magnetic property of matter plays an important role in modern technology. This need intensive research to satisfy technology need for new magnetic properties of matter. This motivates to do this research on the effect of change of nano size of Aluminum on its permeability. Three different nano sizes were prepared. It was found that increase of Aluminum nano size increases its magnetic permeability.

Development Of Radio Frequency Identification Architecture For The Adoption By Utility Companies: A Case Study Of Nairobi City Water And Sewerage Company

Accurate meter readings, timely and correct bills have become an important aspect of water metering systems. Additionally, anomalies such as leakage and bursts in water pipelines have significant consequences to the environment and lead to financial constraints to the water companies. Since monitoring leakages and bursts in the water distribution networks, capturing accurate and dependable measurements for billing, troubleshooting and analysis is a challenging task, the need to develop a reli...

Effect Of Age On Success Rate Of IVF Treatment Among Infertile Sudanese Women

Abstract Infertility is the most widespread and considered as one of the most important unappreciated health problems, particularly in developing countries and about 10% of women failure to achieve a normal pregnancy. This study was conducted to estimate plasma FSH, LH and PRL among infertile Sudanese women. The study included one hundred and fifty women participate in this study and divided into three groups according to the age of participant, group (1) (35- 37 ) years included 44 women, g...

EEG-Based Detection Of Human Emotions

ABSTRACT EEG (Electroencephalography) allows eliciting the mental state of the user, which in turn reveals the user emotion, which is an important factor in HMI (Human Machine Interaction). Researchers across the globe are developing new techniques to increase the EEG accuracy by using different signal processing, statistics, and machine learning techniques. In this work we discuss the most common techniques that can yield better results, along with discussing the common experiment steps to ...

A Design Of Smart Hajj Guide System For Piligrim Identifaction And Location Services

Abstract This dissertation investigates the issues of guidance for pilgrims and how to make it more suitable for groups of pilgrims who navigate in unfamiliar areas. The dissertation will explore how to provide aid to pilgrims in crowded places by developing a pilgrim tracking and identification system using mobile phones that use NFC technology. The proposed system will provide education to pilgrims to guide them throw the Hajj journey. The proposed system will provide instructions regardin...

Synthesis And Characterization Of Carboxymethyl Cellulose From (Date Palm) Phoenix Dactylifera L. Leaves

Abstract The aim of this study was to synthesize and characterize carboxymethyl cellulose (CMC) from Phoenix dactylifera L. )date palm( leaves by etherification reaction using sodium mono chloroacetic acid (MCAA) and sodium hydroxide. The optimum reaction parameters were found to be 55 ⁰C, 30% sodium concentration, 3g MCAA/1g cellulose and 4 hours reaction time to give 0.77 as the highest degree of substitution (DS). FTIR shows that successful isolation of cellulose and the synthesized CMC...

Running Of Quark Mass And Flavor Mixing In Extra Dimension Model

Abstract In this research, the running of quarks masses and flavor mixing in five dimensional standard models has been studied. The evolution properties of quark mass and flavor mixing are performed for the one-loop renormalization group equations in the five dimensional standard model. It is found that the five dimension model has a significant effect on the running of the fermion masses, including both quark and lepton sectors. We quantitatively discussed these quantities for R −1 = 1 Te...
