EXTENDED GENERALIZED GAMMA DISTRIBUTION

New 6-parameters extended form of the Kobayashi's generalized gamma function is defined, several of its properties and recurrence formulas are derived. Based on this new function we introduce a new 6-parameters with a model function extended generalized gamma distribution. Many new distributions are shown to be particular cases of this suggested distribution, including some familiar known distributions. In terms of the model function statistical properties; reliability and hazard functions, and estimation of some parameters of the distribution are studied. Also, the form of the distribution is considered under various forms of the model function. We believe that this new distribution model is reasonable for accommodate

PALAEOCLIMATOLOGY AND PALAEOHYDROLOGY OF LATE PLEISTOCENE PALAEOLAKE AT QA'A SELMA (JORDANIAN BADIA)

Qa'a Selma (as a playa) is located on the northern basaltic flow of northeast Jordan, about 35 km northeast of the Safawi town. The present climate of the region is characterized by seasonal rain (during winter) and it has mild winter and temperate dry summer. Late Pleistocene palaeoclimatic and palaeohydrologic conditions of Qa'a Selma are deduced based on lake level changes. One palaeoshoreline was delineated at 745m a.s.l. and 4m above the present one (1m above the bottom of Qa'a). The Qa'a is located at 740m a.s.l. The present Qa'a area is calculated to equal 18 km2, where its area has increased during the Late Pleistocene pluvial period and calculated to reach 36 km2. The Drainage basin area is calculated as well to equal 15000 km2.

ISOSTATIC CONDITIONS IN SOUTHERN AND EASTERN YEMEN AND THEIR IMPORTANT GEOLOGIC IMPLICATIONS

Fifty-nine gravity basic stations distributed in southern and eastern Yemen are considered to obtain the regional Bouguer anomaly and isostatic maps of the covered region. The obtained maps show many high amplitude negative anomalies which are related to high elevation area and mass deficiency beneath the continental crust.
Isostatically the study region seems to be overcompensated in high land, while it is nearly complete compensation in low land area. The region requires an upwelling of the mantle material to compensate the mass deficiency in the region. Such process also requires uplift in the earth’s surface, which should have a relation with the tectonic and geomorphologic processes acting in the region such erosion. A comple

SHORT PULSE LASER GENERATION USING PHASE SHIFTED FIBER BRAGG GRATING

Short pulse laser generation using phase shifted fiber Bragg grating (FBG) is a theoretical demonstration and investigation in this paper. The specified refractive index can be photo-written in an optical fiber using UV laser with a standard phas mask scanning techniques. Two Bragg gratings were specially designed to spectrally filtering the edges of the input puise. When the FBGs are fabricated in the core of the optical fiber, most of the power travels in the core with a smock part corresponding to the evanescent wave that travels outside near the core in the cladding. The results show the desired full width at half maximum (FWHM) of the pulse propagation in the core of the optical fiber is 5,025 nm, which corresponds to frequency FWHM

PCA TRANSFORM FOR IMAGE ENHANCEMENT, COMPRESSION, AND CHANGE DETECTION

The Principal-Components-Analysis (PCA) of KL-transform has been utilized as multi operators, (i.e. enhancement, compressor, and temporal change detector). Two images pair (Al-Jaderiya-Baghdad-Iraq) of 3-bands Landsat ETM+ (14.25 spatial-resolution) and Panchromatic Quick-Bird (0.6 meter) images are adopted to perform the PC analysis. Since most of the image band's information are presented in the first PCs, therefore image classification and change detection procedures are performed with little consuming time. The linear “PCA” transformation can be used to translate and rotate data into a new coordinate system that maximizes the variance of the data. It can also be implemented for enhancing the information content.

SPECTRAL ANALYSIS AND PHYSICAL PROPERTIES OF MAIN- SEQUENCE STARS

The analysis of stellar spectrum was considered as an efficient tool for studying the chemical composition of stars and measuring the physical properties. In this paper, we selected four stars of the main- sequence band namely (HD 6111, HD 221741, SU Aur, HD 5351) for analyzing their spectra. The chemical composition of each star can be extrapolated from their own absorption spectrum by comparing their positions in the spectrum with those observed from pure source in the laboratory, while from the emission spectra, we measured the physical properties including, temperature, mass, radius, velocity, and lifetime. The results indicated that the selected stars of the main sequence have the chemical composition hydrogen, ionized helium, Fe, C

GROUNDWATER CHEMISTRY OF THE PLIO-PLEISTOCENE AQUIFER OF ERBIL HYDROGEOLOGIC BASIN, N.IRAQ.

The studied aquifer is the Plio-Pleistocene unit of layering mixed facies of gravel, sand, silt and clay with respect to conglomerate. Two hydrochemical groups were identified as bicarbonate and sulphate. Two families in each group are strongly acting with depth and laterally a part from the hydrogeologic boundaries.
The bicarbonate families are Ca-HCO3and Mg-HCO, while that of sulphate are Mg-SOand Na-SO. The distribution map of salinity reflects a trend of increase in salinity which clarify the different flow orientation within the sub-basins. The minimum recorded of salinity is 750 ppm, while the maximum is 7500ppm. The ten folds salinity occurs at the western boundary condition of Avana and Khurmala anticlines, where the Fatha g

MID-CRETACEOUS RADIOLARINS FROM THE BALAMBO FORMATION NE-IRAQ

The late Albian-Early Turonian Radiolarians of the Balambo Formation, which were recovered from well Jambur-18 (NE of Iraq) are characterized by their abundance and diversity. They show certain similarities to those from the Tethys and North Atlantic indicating the ongoing opening between the two basins.
Microfacies analysis for the Balambo rocks indicates a basinal depositional environment, where radiolarians thrived. The differences in depositional textures of the carbonate facies with presence of mudstone and shale units indicate relative changes in depth within the same environment. This can interpreted to the relative changes of sea-level, which exhibit transgressive and regressive cycles. Radiolarian-rich intervals correlate w
