Faranak Feizi, Edris Mansouri
Open Journal of Geology (OJG) , 2013, DOI: 10.4236/ojg.2013.34032

The studied area—Kermejegan—is located in the south of Qom Province, Iran. In this paper, geology map, ASTER and ETM7+ satellite images were used and after processing these images with Geomatica and ENVI softwares, iron potential zones were compared with the iron mine position in the south of the area and 2 dominate indexs around. Finally remote sensing, faults and geological data layers were integrated in GIS and hopeful zones were introduced for continuing the exploration processes.

Separation of Alteration Zones on ASTER Data and Integration with Drainage Geochemical Maps in Soltanieh, Northern Iran  [PDF]
Faranak Feizi, Edris Mansuri
Open Journal of Geology (OJG) , 2013, DOI: 10.4236/ojg.2013.32017

The Soltanieh area is a part of Tarom volcano-plutonic zone that is located in north-west of Zanjan province in northwest of Iran. Advanced Space borne Thermal Emission and Reflection Radiometer (ASTER) image processing have been used for mapping hydrothermal alteration zones in studied area. To separate the alternation zones; False Color Composite (FCC), Least Square Fit (LS-Fit), Minimum Noise Fraction (MNF) and Spectral Angel Mapper (SAM) techniques have been applied on ASTER data and iron oxide, argillic, phyllic and propylitic zones have been separated. At last, the final alteration map is integrated with drainage geochemical maps of Cu, Zn and Pb minerals for introducing the probable high potential zones.

Faranak Feizi, Mehran Arian, Artin Arian
Open Journal of Geology (OJG) , 2015, DOI: 10.4236/ojg.2015.55027
Abstract: The Napag is the biggest Mud Volcano at Makran in Iran. The main aim of this research is the investigation of geologic setting and geographic situation of Napag Mud Volcano as a well-known mud diapir at Makran on the south eastern margin of Iran. The Napag Mud Volcano has been formed during quaternary of as a conical hill on the flat plain in coastal region Oman Sea. There are badlands area and several mud volcanoes that they have been triggered by longitudinal normal faults. This normal faults have been developed in neotectonic regime by the roll-back of oceanic lithosphere (beneath of Oman Sea). Finally, the main characteristics of the Napag mud diapir are presented.

Abstract: um ferritin concentration in gestational diabetes mellitus and risk of subsequent development of early postpartum diabetes mellitus Original Research (3507) Total Article Views Authors: Faranak Sharifi, Amir Ziaee, Abdolamir Feizi, et al Published Date December 2010 Volume 2010:3 Pages 413 - 419 DOI: http://dx.doi.org/10.2147/DMSO.S15049 Faranak Sharifi1, Amir Ziaee2, Abdolamir Feizi3, Nouraddin Mousavinasab1, Afagh Anjomshoaa1, Pooran Mokhtari4 1Zanjan Metabolic Diseases Research Center, Zanjan; 2Qazvin Metabolic Diseases Research Center, Qazvin; 3Zanjan University of Medical Sciences, Zanjan; 4Vali-e-asr Hospital, Zanjan, Iran Purpose: To compare the serum ferritin concentrations of normal pregnant women with those having gestational diabetes mellitus (GDM) and to determine the possible role of ferritin in predicting pregnancy outcome and early development of postpartum glucose intolerance and diabetes mellitus. Method: This case-control study consisted of 128 pregnant women (64 women with GDM and 64 age-matched healthy pregnant women) seen at a university hospital in Zanjan, Iran. Anthropometric measurements were determined, and serum ferritin, C-reactive protein, insulin, glycosylated hemoglobin (HbA1c), and hemoglobin levels were measured. Pregnancy outcomes were recorded in all subjects. In the women with GDM, a diagnostic oral glucose tolerance test was performed eight weeks after delivery. Results: Women with GDM had a higher concentration of serum ferritin (112 ± 28.4 pmol/L in GDM versus 65 ± 16.9 pmol/L in controls, P<0.001). A positive correlation was found between serum ferritin level and mid-pregnancy fasting plasma glucose and HbAlc levels. Although women in the highest quartile of serum ferritin had a greater than two-fold increased risk of GDM, no significant correlation was found between ferritin levels and early postpartum oral glucose tolerance test results. Conclusions: Elevated serum ferritin concentrations in mid-pregnancy are associated with an increased risk of GDM independent of C-reactive protein and body mass index. Ferritin levels in GDM cannot be used as an indicator to predict subsequent glucose concentration in early postpartum oral glucose tolerance test.
Communication Between Deaf Children and Their Hearing Mothers:The Role of Language, Gesture, and Vocalizations
Faranak Sakhedri
Audiology , 2003,
Abstract: In the present longitudinal study, 20 deaf and 20 hearing children were observed during free play with their hearing mothers when the children were 22 months and 3 years of age. Compared to hearing children, deaf children were severely language delayed, with deaf 3-year-olds using less language (speech or sign) than hearing 22-month-olds. Deaf children communicated primarily through nonlinguistic vocalizations, with increasing use of gesture from 22 months to 3 years of age. Although mothers of deaf children used more visual communication than mothers of hearing children, they still primarily communicated through speech. In addition, deaf children did not visually attend to much of their mothers' communication. Therefore, deaf children received much less communication than hearing children. These results suggest that intervention efforts should be focused on increasing the quantity of perceived linguistic input by the child.
Hearing Evaluation in Some Veterans in the Years Between 1996-1997 in Hamedan

Abstract: Background: Many Endogenic and exogenic factors can affect the individual’s susceptibility to noise exposure, for instance middle and outer ear characteristics, the amount of oxygen transmission, skin color, medical history, mental state and the patient’s attention, age, cigarette smoking and many otjher factors affect the amount of noise induced hearing loss and acoustic trauma.The current study was aimed at investigate the impact of various Endogenic and exogenic factors on the amount of PTS and TTS in veterans in Hamedan province.Results: The results of the study manifested that:- Veterans with tinnitus suffered more hearing loss than patients without this symptom. - Extended intensity of noise and exposure time to war noises can exacerbate the amount of hearing loss in veterans who had fight more.- The degree of hearing loss in patients who had previously suffered middle ear infections or otitis or the familial history of hearing loss was more than people without such historyDiscussion: The findings of our study in compatible with the results of other similar studies and confirms the effect of different pathologic and non-pathologic factors on the degree of noise induced hearing loss.
PSC: A Pattern-Based Temporal and Spatial Crowdsourcing Platform to Improve Performance, Reliability, and Privacy
Faranak Davoodi
Computer Science , 2015,
Abstract: In this paper, we study a novel spatial crowdsourcing system where the workers' time availabilities and their spatial locations are known a priori. Consequently, the tasks assignment to workers is performed not only based on the current location of the human workers and the tasks available in the region, but also based on the availability of the workers during the specific times that a given task should be accepted, processed, and completed. Having the system determine the daily pattern of the workers (either by predefined questionnaires when the workers register, or by archiving data from the worker's mobile devices, or by on the road and real-time entered status data) eliminates many unsuccessful task assignments and therefore significantly increases the efficiency of the system. In the original Spatial Crowdsourcing (SC) framework, the SC-server optimizes the task assignment locally at every instance of time and whenever a new task, or a new worker, enters the system. Our new framework (PSC), on the other hand, allows the users to enter their daily routine, and temporal, spatial, and availability patterns a priori. This makes the system much more stable and pattern-opportunistic. The PSC servers can focus on receiving and archiving new entries (e.g., workers, tasks, and their criteria) during busy times (e.g., when there are many new entries in the system), and can focus on optimization and computations during quiet times (e.g., when there are fewer new entries in the system). Having the task optimization process happen during quiet times, and when there are few changes to the system, makes the performance more stable and reliable. It also allows the PSC system to have a global view of the system and and perform global optimizations to improve the performance.

Abstract: This study aimed to investigate the impact of seasonal fluctuations in annual and long-term inventory on stock returns of companies listed on the Stock Exchange in Tehran. A sample of 84 listed in the Tehran Stock Exchange, which their data for a period of 5 years (1388 to 1392) were the statistical analysis. Model study of research Steinker and Hoberg (2014) has been adapted where long-term stock return as the dependent variable is a function of the independent variables. The findings suggest that there is a significant relationship between annual and seasonal abnormal growth of inventory and long-term stock returns. This finding indicates that the capital market has reacted to inventory changes at different times. Based on the above results, it can be covered in the basic hypotheses accepted.
Frequency Domain Approach for Face Recognition Using Optical Vanderlugt Filters  [PDF]
Faranak Heidari, Hassan Kaatuzian, Armin Alizadeh
Optics and Photonics Journal (OPJ) , 2016, DOI: 10.4236/opj.2016.68B016
In this paper human face machine identification is experienced using optical correlation techniques in spatial frequency domain. This approach is tested on ORL dataset of faces which includes face images of 40 subjects, each in 10 different positions. The examined optical setup relies on optical correlation based on developing optical Vanderlugt filters and its basics are described in this article. With the limitation of face database of 40 persons, the recognition is examined successfully with nearly 100% of accuracy in matching the input images with their respective Vanderlugt synthesized filters. Software simulation is implemented by using MATLAB for face identification.
