Buckling of Nonprismatic Column on Varying Elastic Foundation with Arbitrary Boundary Conditions
Citation: Ahmad A. Ghadban, Ahmed H. Al-Rahmani, Hayder A. Rasheed, and Mohammed T. Albahttiti, “Buckling of Nonprismatic Column on Varying Elastic Foundation with Arbitrary Boundary Conditions,” Mathematical Problems in Engineering, vol. 2017, Article ID 5976098, 14 pages, 2017. doi:10.1155/2017/5976098Buckling of nonprismatic single columns with arbitrary boundary conditions resting on a nonuniform elastic foundation may be considered as the most generalized treatment of the subject. The buckling differential equation for such columns is extremely difficult to solve analytically. Thus, the authors propose a numerical approach by discretizing the column into a finite number of segments. Each segment has constants (modulus of elasticity), (moment of inertia), and (subgrade stiffness). Next, an exact analytical solution is derived for each prismatic segment resting on uniform elastic foundation. These segments are then assembled in a matrix from which the critical buckling load is obtained. The derived formulation accounts for different end boundary conditions. Validation is performed by benchmarking the present results against analytical solutions found in the literature, showing excellent agreement. After validation, more examples are solved to illustrate the power and flexibility of the proposed method. Overall, the proposed method provides reasonable results, and the examples solved demonstrate the versatility of the developed approach and some of its many possible applications
EmPOWER: A Testbed for Network Function Virtualization Research and Experimentation
Software Defined Networking (SDN) and Network Function Virtualization (NFV) are making their way into the research agenda of all the major players in the networking domain. Parallely, testbeds and experimental facilities are widely regarded as the fundamental step-stone to future "clean slate" networking. However, designing and building experimental facilities can hardly be considered a trivial step for either researchers and practitioners. Scale, flexibility, and ease of use are just some of the challenges faced by a testbed designer. These considerations are at the base of efforts such as GENI in USA, AKARI in Japan, FEDERICA, NOVI and OFELIA in Europe which provide federated and open facilities for the Future Internet research agenda. Albeit the importance of such facilities is unquestioned, today there is still a dearth of testbed exploiting SDN and NFV concepts in the wireless networking domain. In this paper we present EmPOWER an experimental testbed which aims at filling this gap by offering an open platform on top of which novel concepts can be tested at scale. The EmPOWER testbed is composed by 30 nodes and is currently used by both undergraduate and graduate students at the University of Trento and by the research staff at CREATE-NET
Interference Management in Software-Defined Mobile Networks
Software-Defined Networking promises to deliver more flexible and manageable networks by providing a clear decoupling between control plane and data plane and by implementing the latter in a logically centralized controller. However, if such principles are to be applied also to wireless networks, new primitives and abstractions capable of providing programmers with a global view of the network capturing channel quality and interference must be devised. Moreover, the dynamic radio environment necessitates fast adaptation of physical parameters such as power, modulation and coding schemes. So the wireless SDN abstractions should allow for such adaptations to happen closer to the air interface. In this paper, we present high level abstractions for channel quality, interference and network reconfiguration; the latter permits operations differing in timescales to be carried out at different controller entities. The proposed concepts have been implemented and evaluated over a WiFi-based WLAN. Empirical measurements show that the proposed platform can be used to implement typical WiFi network management tasks such as channel assignment and interference monitoring
Contesting the Saudi State: Islamic voices from a new generation
The terms Wahhabi or Salafi are seen as interchangeable and frequently misunderstood by outsiders. However, as Madawi al-Rasheed explains in a fascinating exploration of Saudi Arabia in the twenty-first century, even Saudis do not agree on their meaning. Under the influence of mass education, printing, new communication technology, and global media, they are forming their own conclusions and debating religion and politics in traditional and novel venues, often violating official taboos and the conservative values of the Saudi society. Drawing on classical religious sources, contemporary readings and interviews, Al-Rasheed presents an ethnography of consent and contest, exploring the fluidity of the boundaries between the religious and political. Bridging the gap between text and context, the author also examines how states and citizens manipulate religious discourse for purely political ends, and how this manipulation generates unpredictable reactions whose control escapes those who initiated them
“Come Think With Me”: Finding Communion in the Liberatory Textual Practices of Kameelah Janan Rasheed
Defining text as anything that can be read, self-identified learner and artist Kameelah Janan Rasheed explores reading as radical communion within her multifaceted textual practice. A 2021 Guggenheim Fellow, Rasheed’s work spans vast bodies of knowledge and temporalities to interrogate both the aesthetic and the limits of the text. At times producing collages with letters cut out from books in her own expansive library, and at other times posting scans from various books that are marked up with her rigorous note-taking, Rasheed approaches the text as an invitation to commune with the author in order to collectively arrive at new ways of knowing and being. Rasheed’s work maps both her own hypertextual engagements while simultaneously enacting a Black feminist approach to literacy, one that recognizes Black women’s textual practices as mapping geographic, corporeal, and psychological sites of resistance.
