Comparative Study of Image Denoising Using Wavelet Transforms and Optimal Threshold and Neighbouring Window

NeighShrink is an efficient image denoising algorithm based on the discrete wavelet
transform (DWT). Its disadvantage is to use a suboptimal universal threshold and identical
neighbouring window size in all wavelet subbands. Dengwen and Wengang proposed an
improved method, which can determine an optimal threshold and neighbouring window size
for every subband by the Stein’s unbiased risk estimate (SURE). Its denoising performance is
considerably superior to NeighShrink and also outperforms SURE-LET, which is an up-todate
denoising algorithm based on the SURE. In this paper different wavelet transform
families are used with this improved method, the results show that Haar wavelet has the
lowest performance among other wavelet functions. The system was implemented using
MATLAB R2010a. The average improvement in term of PSNR between Haar and other
wavelet functions is 1.37dB

The Legal Effects of Breaching the Administrative Contract : A Comparative Study

      The administration concludes two types of civil and administrative contracts, each of which is subject to its own system, and the administrative contract is characterized by a set of exceptional powers towards the contractor in order to compel him to implement his obligations

       And that administrative contracts require a large financial and technical possibility to implement them, especially contracts that focus on strategic projects, including general contracting contracts

      Which is based on the technical competence and merit of the contractor, and accordingly, delay in the implementation of contractual obligations or negligen

The American Occupation Policy toward Japan 1945-1951 and Iraq 2003-2008: Comparative Historical Study

With their strategic and geographical positions, Japan and Iraq are one of the major
countries in the world, especially to the United States. Japan lies near the two American
Continents, separated only by the Pacific and it is only normal to have the interests of both
countries crossed and joined in the Far East region. This made the occupation of Japan an
inventible matter in the second half of the 20th century. Iraq, on the other hand, has strategic
position in the Middle East, being surrounded by many active countries like Turkey, Iran, and
Gulf countries, besides Iraq’s oil wealth which is needed by such industrial country like the
United States.

Buying offers and their impact on stock trading in the stock market: A comparative study

A share purchase offer is a legal process whereby a natural or legal person offers to the shareholders of a particular company the desire to buy the shares they own. Shareholders have the choice between accepting or rejecting the offer within a specified period of time. This purchase is a fixed price that is often higher than the price price; for the purpose of encouraging the shareholders of the target company to sell their shares to the bidder. Although stock purchase offers are one of the methods or methods of corporate control, they differ from other forms of control, such as mergers and purchase of shares from the stock market. The process of stock purchase offers is governed by a set of principles that must be adhered to, Informati

A Comparative Study between Dusting and Fragmentation in Intracorporeal Laser Lithotripsy in Distal Ureteric Stone

Background: Ureteric stones commonly have an impact on the quality of life of the patient. There are many treatment choices for the condition, including medical treatment, extra-corporeal shock wave lithotripsy (ESWL), endoscopic intervention by ureteroscope (URS), or surgery (open or laparoscopic). Semi-rigid URS with laser lithotripsy is used to fragment ureteric stones, especially those in the distal ureter.

Objectives: To assess the efficacy and complications of the dusting versus the fragmentation method for lower ureteric stones using holmium laser lithotripsy by analyzing intra-operative and post-operative variables.

Patients and methods: One hundred and twenty patie

The link of destination Using the evidence Analytical Fundamental Study

This paper seeks to study the link between the fundamentalist evidence based on the observance of governance and interests and the ranks of the three legitimate purposes (necessary, need and detailed). The researcher followed the descriptive-analytical approach. The study reached important results, including that the measurement relates to the three ranks, but predominantly attached to measure the meaning of the need and the need, and the measurement of the semi-formal and semi-predominance improvement. Reclamation is considered by the majority of scholars to be authentic if it is related to the necessity and the need, and that it is not acceptable to improve only by a witness who recommends it. The excuses relate to Hajji and Tahini, no

Criminalization of Graft in Palestinian Legislation between Constitutional Legitimacy and Procedural Necessity : A Comparative Study

This study aimed to identify the extent of the constitutionality of proving the crime of graft regarding transferring the burden of proof to the accused and its violation of the presumption of innocence. The presumption of innocence, unlike the Kuwaiti legislator, who did not shift the burden of proof in the crimes of illegitimate gain, and that the proof of the crimes of illegitimate gain according to the Palestinian and Jordanian legislators are linked to two forms: actual exploitation and judgmental or presumed exploitation, while the Kuwaiti legislator has limited proof of illegitimate gain crimes in the form of The study recommended a set of recommendations for an amendment to the text of Article 3 of Decree Law No. 37 of 2018 regar

Astronomi cal Color Image Compression Using Multilevel Block Truncation Coding –Modified Vector Quantization Technique

A common approach to the color image compression was started by transform
the red, green, and blue or (RGB) color model to a desire color model, then applying
compression techniques, and finally retransform the results into RGB model In this
paper, a new color image compression method based on multilevel block truncation
coding (MBTC) and vector quantization is presented. By exploiting human visual
system response for color, bit allocation process is implemented to distribute the bits
for encoding in more effective away.
To improve the performance efficiency of vector quantization (VQ),
modifications have been implemented. To combines the simple computational and
edge preservation properties of MBTC with high c
