DWT-Based Data Hiding Technique for Videos Ownership Protection

This chapter proposes a wavelet data hiding scheme for video authentication and ownership protection. A watermark in the shape of a logo image will be hidden. In this research, a discrete wavelet transform (DWT) process is implemented using orthonormal filter banks, where the Y components of the YUV color space of the video frames are decomposed using DWT, and a watermark is inserted in one or more of the resulting sub-bands in a way that is fully controlled by the owner. Then, the watermarked video is reconstructed. The filters used for the DWT decompositions are randomly generated to increase the security of the algorithm. An enhanced detection technique is developed to increase the reliability of the system. The overall robustness of this scheme is measured when common attacks are applied to the test videos. Moreover, the proposed algorithm is used with the high-efficiency video coding (HEVC) technique to examine the whole performance. Furthermore, a selective denoising filter is built to eliminate the effect of the noise. The simulation results show that the proposed algorithm achieves well under both the visual and the metric tests. Moreover, it performed well against intentional and unintentional attacks. The average normalized correlation achieved is 97%, while the mean peak signal-to-noise ratio (PSNR) is 45 dB

Kebijakan Syari’at Islam menjadi pertimbangan yang menyeluruh terhadap segala kebijakan yang berhubungan terhadap Qanun yang dikeluarkan oleh Pemerintah Aceh. MPU Aceh memiliki peranan yang sangat penting dalam rangka pemantapan implementasi Syariat Islam di Aceh karena peran MPU sebagai pemberi pertimbangan kepada Pemerintah Aceh dan DPRA dalam pembentukan sebuah rancangan Qanun (Perda) Aceh. Tujuan dari penelitian ini adalah, Pertama untuk meninjau apakah lembaga MPU yang bersifat independen tersebut melakukan intervensi terhadap kebijakan lembaga lainnya. Kedua, untuk menilai apakah fatwa yang dikeluarkan oleh MPU jika tidak dijakankan akan memiliki dampak terhadap lembaga vertikal lainnya. Metode penelitian yang digunakan adalah penelitian doktrainer dengan basis data sekunder. Urgensi penelitian ini adalah meneliti kedudukan MPU terhadap lembaga vertikal lainnya dan melihat kekuatan fatwa MPU terhadap pengaruh keputusan lembaga vertikal lainnya. Hasil penelitian ini menunjukkan: 1) Kewenanangan MPU dalam mengeluarkan fatwa belum pernah terdapat adanya tumpang tindih kebijakan yang bertentangan, 2) Implikasi kebijakan dari MPU sangat mempengaruhi dan mengintervensi kondisi sosial serta menjadi pertimbangan terhadap lembaga vertikal lainnya. 3) Hubungan Tata kerja antara MPU dan lembaga Vertikal lainnya dimaksudkan untuk tidak adanya kontradiktif terhadap pelaksanaan Syariat Islam, namun fatwa yang dikeluarkan oleh MPU tidak dapat mengikat secara maksimal terhadap keputusan lembaga vertikal lainya karena hanya berbentuk rekomendasi yang dapat dijalankan atau tidak dijalankan

G2G interaction model of information sharing among local agencies based on phenomenology approach: Dhi-qar province employees’ viewpoints

The exchange of information electronically has help local agencies to increase their productivity and performance. At the same time, it improves the process of policy-making by providing better public services to citizens. However, only a few studies that examine the factors influencing the electronic interaction among local agencies in developing countries, including in Iraq. In fact, government agencies usually rely on information provided by other government agencies, making the electronic interactions crucial for effective inter-organizational operations management in the government. This study aims to determine the factors affecting the interaction among local agencies in Dhi-Qar, Iraq. Thus, it proposes a government-to-government (G2G) interaction model among local agencies from the environmental, organizational, and technological contexts, using phenomenological approach based on the Diffusion of Innovation and Social Exchange theories. Data were collected in two phases. First, a series of interviews with local egovernment employees were carried out to discover the factors that influence the G2G interaction in Dhi-Qar, Iraq. Later, another series of semi-structured interviews focusing on extracting the main issues that influence G2G interaction was followed. The collected data were validated through triangulation and member checking. A case study was used to confirm the findings. The study has discovered the factors that influence the electronic interaction among local agencies in Dhi-Qar. The factors are benefits, compatibility, complexity, costs, information security, inter-agency trust, internal resistance to change, information technology (IT) capability, legislation, physical security, and top management support. Based on these factors, the government-to-government interaction model (G2GIM) is proposed. This model can be applied to different local agencies in implementing e-government projects

Studies of non-chemical strategies for postharvest management of Mediterranean fruit fly (Ceratitis capitata)

The Mediterranean fruit fly Ceratitis capitata (Medfly), is a highly polyphagous insect species with a host range of over 400 plant species. It is one of the most destructive horticultural insect pests which has resulted in huge pre and postharvest losses, costing billions of dollars every year for pest management. Quarantine and phytosanitary treatments are essential to ensure no live Medfly in imported and exported fruit, vegetable and hay. However, it is increasingly difficult to be clarified due to the ban of key pesticides, methyl bromide, an ozone-depleting substance, and chemical residues related food and consumer safety issues. Therefore, the non-chemical strategies, including the controlled atmosphere (CA), heat and low temperature and irradiation treatments have been applied for eradication of fruit flies in postharvest fruits. However, the response of Medfly to low-temperature and low-oxygen has not been extensively studied in the lab diet and blueberries. My Ph.D. research has systematically evaluated low-temperature and low-oxygen treatments of Medfly on a lab diet and two blueberry cultivars. The results demonstrated that in the lab diet, both the 1st and 3rd larval instars were the most cold-tolerant stages. In blueberries, the 3rd larval instar was the most cold-tolerant stage. In the low-oxygen/high-nitrogen treatment, the 3rd larval instar was the most tolerant stage at 25°C. No significant differences in sex ratios of survived Medfly were observed between treated and non-treated Medfly populations after both low-temperature and low-oxygen treatments. This study improved our understanding of Medfly responses to low-temperature and low-oxygen treatments. The results and knowledge will help refine current fruit fly postharvest management and develop more efficient and environmentally friendly control approaches, which will contribute to the integrated postharvest pest management strategies for Medfly

Value of Serum Cystatin C in Predicting Early Renal Impairment in Type 2 Diabetes Iraqi Patients

Background: Diabetes mellitus comprises a heterogenous group of metabolic disorders that share the common feature of hyperglycemia due to defects in insulin secretion, insulin action or both. Diabetes mellitus represents the most common metabolic disease worldwide. DM is the most frequent contributor to end stage renal disease. Microalbuminurea is currently the earliest easily detectable laboratory marker of diabetic nephropathy. Cystatin C is a protease inhibitor secreted at a constant rate by cells and released into bloodstream and detected in almost all body fluids. The aim of the present study was to see whether cystain C is elevated before the appearance of microalbuminurea in type 2 diabetic patients.Subjects Materials and Methods: The study was designed to be an observational case control study and was conducted in Al karama teaching hospital in Wassit governorate from January 2015 through November 2015. A random sample of type 2 DM patients was selected with an age range of 43-73 years. A comparable number of 79, 40 males and 39 females, apparently healthy control subjects was randomly selected with an age range of 44-86 years. Serum cystatin was measured for all patients. Results: Mean blood urea and serum creatinine were not significantly different between patient and control group (P>0.05), while mean serum cystatin c was significantly higher in patients than in control group, 0.80+0.18 versus 0.56+0.24 µg/ml, (P<0.001), Serum cystatin c was not significantly affected by, age, gender, weight, serum creatinine, blood urea and HbA1c in both groups.Conclusion: serum cystatin c is a useful marker for early detection of renal function detorioration deterioration in type 2DM patients before the development of microalbuminurea. Keywords: Cystatin C, type 2 D
