Abstract

Traffic Road-Signs contain useful information for the road users; the operation of many of modern applications like the automatic or smart vehicle requires an automatic discrimination of the texts of the traffic road-sign. Discrimination of text compose of several stages, the first of these stages is detection and extraction of the texts. In this work, an algorithm is developed to detect, locate, and segment of the texts and the word in the video clips, that existing in the road signs in the city of Baghdad. The proposed approach includes two stages, the first one is processing the image to locate and extract images of the road-sign and neglect the rest of the image, and the second stage is processing the image of the road-sign plate to detect and extract the texts without symbols and shapes. The basic structure of the algorithm depends on the following functions: edge-detector, dilation, and filling-hole, morphological-opening. The total recall values of 89%, the total precision value of 93%.The algorithm is, then, tested based on video clips, implementation of the algorithm based on video clips confirms its ability to detect the texts which may appear in the video scenes, recall-rate(r) is excellent with a total value of 94.5% and a total precision value of 86.5%.The algorithm is tested to measure its validity to work under real-time operation, by processing one frame and exceed a set of next frames, the test appears that the algorithm is able to work under real-time operation with recall-rate(r) of(93%).

Abstract

Unwanted e-mails became one of the most risk experienced by e-mail users, which may be either harmless or e-mails thatrepresenta threatto the internet.Filtering systems are used to filter e-mail messages from spam. This paper introduces a proposed hybrid system to filter the spam; the proposalhybrid Ant Colony System (ACS) and Naive Bayesian (NB) classifier. Where, ACS will dependon the Information Gain (IG) as a heuristic measure to guide the ants search to select the optimal worst features then omitting these features. The remind features will be the subset which is used to train and test NB classifier to classify whether the mail message spam or not.The proposal is experimented on spambase dataset, and the results showthat; the accuracy, precision and recall with NB which use a subset of features extracted by proposing IG-based ACS is higher than the traditional NB with all set of features.

Abstract

This paper presents suggested modified algorithm to draw the geographic maps. Cubic spline interpolation had been used to draw these maps by generating intermediate points between each two points from a set of given points, where these intermediate points represent the control points which they are used to constrain the curvature of cubic spline depending on a value named divisor value that representsthe distance between any two adjacent points at spline knots, and specified by the user. Intermediate points have a great effect on curve shape, through dividing the interval between two adjacent points into equal subintervals. This makes the results of the weights ai, bi and ci in spline function will be equal to zero and di has already been determined to be di = yi , according the equations determining the weights,. So we can draw lines and polygons that are necessary in drawinggeographic maps.

Abstract

The damaging effect of oil products on concrete besides the high permeability of concretehave made researchers try to improve the properties of concrete exposed to oil products, hence improving the durability and serviceability of oil concrete structures. Polymer concrete exposed to oil products is one of a new field that deals with the enhancement of concrete durability. In the present work polyester resin concrete was used and then immersed in different types of oil exposure liquids (gasoline, gas oil and kerosene) compared with reference concrete which left in the air. Polyester resin concrete is used as a new type in this field, it is noteworthy that the use of this concrete gives good test results that raise the values of the mechanical properties, so we did the SEM test in an attempt to study the microstructure of this concrete after soaking for 90 days in oil products.

Abstract

This study is made for determining wind speed frequency distributions at any height within Surface Layer SL (SL has height about 250m above ground) ,where wind speed is measured at low reference level (usually 10m) which is considered a routine meteorological data recorded hourly. This study needs to know in detail the roughness characteristics of the terrain surrounding the location study, that important to calculate the rate of growth of internal boundary layers resulting from discontinuities in roughness as well as the shape of wind profile in various layers. The shape characteristics of the wind profile are determined as a function of roughness length and stability and the result of this profile is compared with measurements from radiosonde, at height 10, 50,100,150, 200m. This study tested frequency percent for wind speed at 10m, 50m, 200m for the observed and calculated at July– month 1990 and at the 12:00 hour only. The calculated wind frequency has weak at 10m wind speed and all the frequency is concentrated at the (2-6) m/s, while the observed has high frequency at the wind speed reached to 8m/s. This case is changed at the height 50m, and 200m where the calculated have high frequency at the wind speed concentrated at (6-10) m/s. This study refers to the possibility of installing turbine in this layer to generate electricity at least in this period of this year.

Abstract

Character recognition has been very popular and interested area for researches, and it continues to be a challenging and impressive research topic due to its diverse applicable environment. The optical character recognition has been introduced as a fast and accurate method to convert both existing text images as well as large archives of existing paper documents to editable digital text format. However, existing optical character recognition algorithms suffer from flawed tradeoffs between accuracy and speed, making them less effective and impractical for large and complex documents. This paper describes a suggested method for Assyrian optical character recognition using modified back propagation artificial neural network based on moments. The experimental results show that the proposed method achieves higher recognition accuracy rate in compared with the standard algorithm.

Abstract

Internet is the largest network that transfers a huge amount of information through the web and that requires data transfer between many network bottlenecks, devices and different hardware technologies. This data movement requires data transfer between many application, software’s and operating systems. Many theses and researches were published in the topic of solving the issue of extreme data transfer rate; this issue causes time consuming problems. There are many technologies of transferring data across the internet; two of the major data transfer technologies are the User Datagram Protocol (UDP) and Transmission Control Protocol (TCP). Those different data transfer technologies through the internet cause most of the servers much of their time translating the data from one technology to another because most of the servers deal with one data transfer technology and therefore it has to translate all other technologies to the technology that it deals with. This research establishes a Server named TCP-UDP Server (TUS), to receive data from both UDP and TCP nodes through the same path without the need of changing the network entities or protocols connected to the server and to avoid the need for transferring the data from the (UDP) form to the (TCP) form and vise versa. All the operations performed by the server are accomplished without any hardware intrusion to avoid time consuming. The TUS server as many servers support the multithreading technology to serve a large amount of nodes at the same time. Each node has its own thread to deal with. This thread has its own life time determined by many facts, and that in turn decides to terminate the thread or not.

Abstract

Silver nanowires (Ag NWs) have been attracted much attention in recent years .view of the extensive its use in various fields. Ag NWs were successfully prepared by two steps firstly electrochemical method and heating secondly silver nanoparticles colloidal solution at different temperature. The optical results show that the position of the plasmon absorption peak depends on the particle size and shape and the adsorption of surfactant to the particle surface. It was noticed that the plasmon absorption peak shifts toward shorter wavelengths (blue shift) as increased temperature.SEM result appeared that silver nanoparticles transformed to Silver nanowires by heating. XRD results explained that the intensity of peak at 64.46° was increased as heating increase much higher at 38.18° which indicted wire growth . The results zeta potential showed that all samples preparation shown across all the zeta potential tests were negative .
