Blind image separation based on exponentiated transmuted Weibull distribution

In recent years the processing of blind image separation has been investigated. As a result, a number of feature extraction algorithms for direct application of such image structures have been developed. For example, separation of mixed fingerprints found in any crime scene, in which a mixture of two or more fingerprints may be obtained, for identification, we have to separate them. In this paper, we have proposed a new technique for separating a multiple mixed images based on exponentiated transmuted Weibull distribution. To adaptively estimate the parameters of such score functions, an efficient method based on maximum likelihood and genetic algorithm will be used. We also calculate the accuracy of this proposed distribution and compare the algorithmic performance using the efficient approach with other previous generalized distributions. We find from the numerical results that the proposed distribution has flexibility and an efficient resultComment: 14 pages, 12 figures, 4 tables.

A review on formability prediction and constitutive damage models of sheet forming of magnesium alloys

In recent years, the demand for using magnesium (Mg) alloys has significantly increased in several industrial fields. Due to their favorable strength/weight ratio thus Mg alloy demonstrating a valid replacement for aluminum alloys and High Strength Steels particularly for the production of lightweight parts in aerospace and automotive industries. However the formability of Mg at cold forming conditions is significantly poor and determination of the material formability need special testing procedures and understanding of material failure mechanism. FLD is commonly used to characterize the formability of materials and the key feature of FLD is the forming limit curve (FLC). This paper provides a review on the determination of strain-based and stress-based forming limit diagrams is introduced in this paper. In addition, the constitutive damage models for predicting and characterizing the forming limits of magnesium alloy sheet metals under a wide range of forming conditions at both industrial and scientific level

Rheology Of Cement Paste Containning Chemical Admixtures

Understanding the Rheology of cement and water is a not a simple task since, thebehaviour of complicated system varies with time and there is still a great deal of work to bedone before, it is properly understood. In this study, we used a new simple and cheaptechnique to evaluate flow properties of cement paste .This technique is based on dropping aneedle from a constant height. The penetration depth is measured at different circumstances,different w/c ratios, different types of super plasticizer, and different percentage of admixturefor two types of cement types of cements OPC type V (CEMEX) and OPC type I (HELWAN)were considered in this study. Also, effect of retempering on penetration depth were alsoconsidered. Finally effect of variation of needle drop height was also considered. Thepenetration depth technique proved to be effective in monitoring the effect ofsuperplasticizer/cement ratio percentage, effect of time, manual remixing after 30 minutesand needle drop height on the rheological behavior of different types of cement paste, whichfurther proves the effectiveness of this method in evaluation of cement paste Rheology

Federalism and the Arab League: A theoretical synergy

Abstract. The paper is a theoretical analogy of the Arab league as a regional organization. The paper also discusses the objectives, strengths and weaknesses of the league. By adopting descriptive-historical research from library instrument, findings show that, there is no doubt that the league had recorded some appreciable level of achievements since its inception and there have equally been some challenges along the line. The paper concludes that, the Arab league must find a way to reduce the perpetual tension and violence in Palestine by working towards enthroning a peaceful relationship with Israel while retaining their cultural identity. The paper also recommends that, the Arab league should strengthen their relationship with the non-Arab Nations especially in the face of globalization to reap the benefits therein involved as a league. Arab league must ensure that Arab states stop waging needless wars between and among themselves. The Syria and Yemeni crises among others is a disgrace to the Arab world.Keywords: Arab league, Theoretical, Synergy, Federalism, Integration.JEL. A10, F15

Integrated microfossil biostratigraphy, facies distribution, and depositional sequences of the upper Turonian to Campanian succession in northeast Egypt and Jordan

Six upper Turonian to Campanian sections in Egypt (Sinai) and Jordan were studied for their microfossil biostratigraphy (calcareous nannofossils and planktonic foraminifera), facies distribution and sequence stratigraphic frameworks. Carbonate (mostly chalk) and chert lithofacies dominate the basinward northern sections passing laterally and vertically to mixed carbonate/siliciclastic lithofacies towards the shoreline in the southeast. Twenty-six lithofacies types have been identified and grouped into six lithofacies associations: littoral siliciclastic facies belt; peritidal carbonate; intertidal carbonate platform/ramp; high-energy ooidal shoals and shelly biostromes; shallow subtidal; and pelagic facies association. The following calcareous nannofossil biozones were recognized: Luianorhabdus malefomis (CC12) (late Turonian), Micula staurophora (CC14) (early Coniacian), Reinhardtites anthophorus (CC15) (late Coniacian), Lucianorhabdus cayeuxii (CC16) (early Santonian) and Broinsonia parca parca (CC18) (Campanian). Equivalent planktonic foraminifera zones recognized are: Dicarinella concavata (Coniacian), the lower most part of Dicarinella asymetrica (earliest Santonian) and Globotruncanita elevata (early Campanian). The integrated zonation presented here is considered to provide higher resolution than the use of either group alone. The absence of calcareous nannofossil biozones CC13 and CC17 in most of the studied sections, associated with regional vertical lithofacies changes, indicates that recognition of the Turonian/Coniacian and Santonian/Campanian stage boundary intervals in the region have been hampered by depositional hiatuses at major sequence boundaries resulting in incomplete sections. These disconformities are attributed to eustatic sea-level fluctuations and regional tectonics resulting from flexuring of the Syrian Arc fold belt. The Coniacian to Santonian succession can be divided into three third-order depositional sequences, which are bounded by four widely recognized sequence boundaries

Factors Associated with Contraceptive Use among Jordanian Muslim Women: Implications for Health and Social Policy

The objectives of this quantitative study were to identify factors associated with contraceptive use by Jordanian Muslim women; to estimate factors that predict the variance in contraceptive use; and recommend appropriate health and social policies to enhance quality of life of Jordanian women. A cross -sectional design was used to collect data from 487 married non-pregnant women aged 18 to 49 years who resided in three southern governorates in Jordan using a structured interview guide. Results showed that 63.2% of women used some form of contraceptive method; IUD was the most frequently used method (44.2%). The percentage of women exposed to violence was 5% and 9.2% for physical and verbal abuse respectively. Findings also showed that there was a significant relationship between psychological wellbeing of women and contraceptive use. Furthermore, no relationship between women’s perceived religious stance towards contraceptives and their use. Predictors of contraceptive use were: women aged 40-45 years explained 23.3% of the variance in contraceptive use; and the woman’s approval of contraceptive use for birth spacing explained 21.4% of the variance in contraceptive use. The Islamic stance towards contraceptive use was not significant in these women; however further studies are needed to confirm these findings as well as the generalizability to Muslim women in other countries. The study findings have implications for health and social policies relevant to family planning services in order to enhance and increase the use of contraceptives to reduce the TFR in Jordan. Furthermore, health care providers, social and economical policy makers need to integrate women’s cultural views and contraceptive use in strategies and policies beyond health to improve women’s quality of life and build on the global consensus for women and children to achieve the Millennium Development goals
