14 Reference 41MasterDistributed Denial of Service attack is a challenging threat to current internet world. Due to thousands of vulnerable machines connected to internet, hackers need little preparation to launch a highly destructive attack. Attacks can be easily downloaded and launched through these fertilized zombie machines. While defense mechanisms and trace back is highly inefficient due to high number of attack machines.
Researchers and commercial organizations are putting all there efforts to deal with the DDoS attack problem but the problem is still unsolved. In this thesis we discussed the DDoS problem in two directions: 1) Cause of problem. 2) Design (architecture and implementation) of defense of DDoS problem which we named PMS that highly prevents the spoofed IP packets to consume legitimate internet bandwidth.
In PMS, the packet is marked by the routers which come along the path to the destination. The packets traveling along the same path will have the same marking which will be dynamically changed after certain span of time. PMS can not only defend against the DDoS attack but also it can deal with the TCP hijacking and multicast source spoofing attacks. PMS defense mechanism just needs to identify only one malicious packet to identify the attack. PMS also supports incremental deployment which enhances its effectiveness against the DDoS attack. PMS scheme effectively defend the network from DDoS attack

Dalam penyajian hasil analisis data digunakan metode informal atau naratif. Hasil peneliti ini menunjukkan bahwa dilihat dari bentuknya Cerita Rakyat Usman Berkat dikategorikan sebagai teks naratif yang struktur atau bentuk teksnya terdiri atas lima bagian, yaitu orientasi, komplikasi, resolusi, reorientasi, dan koda. Berdasarkan hasil analisis bentuk, cerita rakyat Usman Berkat juga mengemban fungsi (hiburan, sarana religius, sarana pendidikan dan pengontrol sosial), makna (historis, religius, didaktis dan sosiologis) dan nilai (solidaritas, religius, hidup, guna, etika dan nikmat) yang dapat dijadikan sebagai penuntun moral, pedoman rtika dalam realitas kehidupan masyarakat Blagar. Seirama dengan perkembangan arus global, yang mempengaruhi berbagai aspek kahidupan manusia, terjadi pula perubahan sikap dan prilaku masyarakat Blagar yang cukup melenceng jauh dari norma dan nilai yang diwariskan para leluhur mereka.

tumbuh dan besarnya tidaklah terlepas dari kehidupan alam desa yang ramah dan damai. Semangat patriotik yang dimilikinya merupakan pembawaan dan ditempa oleh alam sekitarnya. Semangat patriotik yang dimiliki Usman tumbuh dan mekar oleh karena situasi politik yang dianut pemerintah waktu itu. Usman yang masih muda remaja, panas darahnya dan bergelora jiwanya mendengar bahwa tanah airnya sebagian masih diduduki oleh bangsa asing. Komando Trikora yang dikumandangkan oleh Presiden Sukarno memanggil hati setiap pemuda begitu juga Usman tidak melewatkan kesempatan ini. Ia turut menyumbangkan darma baktinya terhadap kepentingan negara dan bangsa. Secara berpadu ia mebulatkan tekad untuk mendaftarkan diri sebagai sukarelawan bersama pemuda dari seluruh pelosok tanah air Indonesia. Setelah dididik dan dilatih dalam beberapa ketrampilan dan keahlian dalam bidang kemiliteran ia diterjunkan ke arena perang untuk melakukan tugas. Pendidikan yang didapatnya menjadikan dirinya prajurit yang disiplin, patuh dan menjadi prajurit yang sapta margais sejati. Dari sinilah awal karier ya dalam bidang militer dan dijalankannya sampai akhir hidupnya

For Inquiries: Please contact Professor Fallou Ngom ([email protected]).Provenance and Condition: This manuscript is owned by Sheikh Alhaji Abdurrahman Aboki, the Chief Imam of Central Mosque of the Federal Polytechnic, Bida—Niger state (from Middle Belt, Nigeria). This is one of the manuscripts he shared with us during our video interview with him in 2019.These materials are collectively called "Political posters in Nupe Ajami." The four (4) posters were unlike most Ajami manuscripts in sub-Saharan Africa, since the scribe -- Alhaji Abubakar used the Mashriqi style rather than the Maghribi. These posters speak to the importance of Nupe Ajami in the people’s day-to-day activities. They also point to the fact that Ajami script has been used for both sacred and secular purposes. Included below is a summary of the contents of each poster:
1. A poster published during the recently conducted 2019 general elections. It depicts the image of the then Presidential candidate, Muhammadu Buhari under the banner of the All Progressive Congress (APC), who eventually emerged the winner for the second term. The translation of the Nupe Ajami inscription at the top reads "Vote President 2019" and the second line says "Let's vote credible president for positive change." To the left is the political party's logo. The last Nupe Ajami inscription, beneath the candidate's image (in red) also says "For president." Lastly, the candidate’s name is written in Latin script.
