Steganography methods using network protocolsDr Amira Bibo
The covert channels of type covert storage channels were used in this research to
hide textual data or an (image hiding secrete data) in the transmission protocol layer and
the internet protocol layer of TCP/IP module. We use IP protocol in designing covert
channel by using Identification field, and use TCP protocol in designing covert channel
by using Urgent Pointer field, and UDP by using Source Port field. Finally ICMP
protocol by using Echo request message and Message field.
The result of Covert channel after analyzing the protocols (IP, TCP, UDP,
ICMP) header depends on the field that used in the designing the Covert channel. The
access ratio of hidden data in the two protocols TCP/IP was %100. UDP protocol on the
other hand depends on a mechanism of unsafe communication. ICMP protocol provided
a good transmission, though unreliable, in that the message structure can be unreliable
or clear.
This document discusses next generation internet over satellite networks. It covers new services and applications for internet integrated services, modeling elastic and inelastic traffic, quality of service provisioning, traffic modeling techniques, and statistical methods for modeling different types of traffic including renewal processes and Markov models. It also discusses traffic engineering principles, multi-protocol label switching, internet protocol version 6, and the future development of satellite networking.

Future Sat Africa - Space Applications for Sustainable Development of AfricaMyles Freedman
This document discusses space applications as a strategy for sustainable development in Africa. It provides an overview of the Entoto Observatory and Research Center (EORC) in Ethiopia, including its vision, mission, training programs, and research areas like astronomy, space science, remote sensing, and geodesy. Benefits of investing in space education and research include economic gains in agriculture, land management, and more, as well as social benefits like education, communication, and disaster response. The document recommends expanding education and research collaboration between African institutions, conducting joint projects with international partners, and collectively addressing legal issues to help develop African space programs and applications.

1) This open-label phase II trial evaluated the efficacy of panitumumab in combination with gemcitabine and oxaliplatin (GemOx) in patients with KRAS wild-type biliary tract cancer.
2) The response rate was 50% with this combination, and median progression-free survival and overall survival were 10.6 months and 20.3 months respectively.
3) The combination showed manageable toxicity and was well-tolerated by patients.
This document defines and describes different types of listening. It begins by defining listening as a conscious process that requires giving full concentration to received sounds, comprehending them, and responding. It then outlines five types of listening: marginal listening, where the listener only hears part of the message; intolerant listening, where the listener interrupts and doesn't give the speaker time; listening for pleasure, which is common when the listener enjoys the topic; active listening, which is attentive, engaged, and done with a purpose to understand; and passive listening, which meets the standards of hearing but lacks motivation or interest from the listener.
This document provides a summary of an individual's qualifications for an operator role. It outlines 8.5 years of experience as an operator in India and Saudi Arabia, including experience operating ammonia plants and utilities. Educational qualifications include a Bachelor's degree in chemistry. Responsibilities have included operating equipment in areas like reforming, acid gas removal, refrigeration, and distillation. Safety training and qualifications are also mentioned. The individual is seeking an operator role utilizing their experience.
El documento presenta el Baix Llobregat como una zona cercana a Barcelona con excelentes accesos, incluyendo el aeropuerto de Barcelona-El Prat, y una amplia oferta de actividades y servicios para eventos. Cuenta con espacios singulares, hoteles exclusivos, restaurantes y otros equipamientos preparados para hacer del Baix Llobregat un destino de primer orden para convenciones, congresos y eventos empresariales.
The We Care Project, founded by Pastor Blessing Chipere Sunday, aims to sponsor underprivileged girls in Nelspruit, South Africa by providing sanitary pads, as many miss school during their monthly periods due to lack of proper supplies. The organization requests donations of any brand of pads or tampons to help these girls and appeals to businesses, organizations, and individuals in Nelspruit to join in this caring initiative by contributing funds to the provided bank account details.
The document describes a collection of watercolor paintings of birds created by Joseph Mallord William Turner while staying at Farnley Hall. It notes that the paintings go beyond scientific recording and provide exquisite renderings of various birds, including robins, doves, pheasants, turkeys, peacocks, and others. The original paintings can be viewed at the Leeds City Art Gallery.
This lesson plan outlines a biology class for 9th standard students about the circulatory pathways topic of blood. The 40-minute class will use lecture, group discussion, and questioning to develop students' factual, conceptual, procedural, and meta cognitive knowledge about blood. Students will learn new terms like blood, immunity, and platelets. Through a video and activity identifying blood cells, students will learn facts about blood constituents like red blood cells, white blood cells, and platelets. The lesson aims to explain blood's major role in carrying out vital functions and developing students' understanding and skills in identifying blood cells.
Este documento resume aspectos clave de la cultura japonesa, incluyendo su vestimenta tradicional como el kimono, su sofisticada gastronomía basada en arroz y otros cereales, y la influencia de varias religiones como el budismo y el shintoismo en la vida cotidiana de los japoneses.
El documento presenta información sobre la economía japonesa. Incluye secciones sobre la organización del blog que contiene la información, con etiquetas y recursos adicionales para el lector. También proporciona referencias bibliográficas sobre temas relacionados con Japón como su desarrollo económico, voluntariado y política macroeconómica.
The document provides fire safety tips for home heating methods during winter, including wood-burning stoves, fireplaces, kerosene heaters, furnaces, and other appliances. It recommends having heating systems professionally inspected and maintained, using fuel only as directed, keeping combustibles away from heat sources, disposing of ashes safely, and installing smoke alarms on every level of the home. Proper safety precautions are emphasized to prevent residential fires from space heaters, fireplaces, furnaces, and other common winter heating sources.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against developing mental illness and improve symptoms for those who already suffer from conditions like anxiety and depression.

The document discusses notes on the Weibull distribution. It describes the two-parameter and three-parameter Weibull distributions as well as the five-parameter bi-Weibull distribution. It also examines the relationships between the Weibull distribution and other distributions like exponential, chi, gamma, and Gumbel distributions. Important applications of the Weibull distribution in reliability are also considered. Parameter estimation methods like maximum likelihood estimation are discussed.
