A secondary gonadal shield for use in the pelvic irradiation of males was designed and built using material and apparatus available with the Cerrobend blocking system. The gonadal dose was reduced to approximately 1.5 to 2.5% of the given dose.

Shielding effectiveness measurements for ferromagnetic shields
2007 IEEE Instrumentation & Measurement Technology Conference IMTC 2007, 2007This paper proposes a new way to measure the shielding effectiveness of ferromagnetic shields. The procedure combines an experimental characterization of the shielding material to a forthcoming numeric simulation. Magnetic hysteresis is reduced to a series of equivalent B-H linear relations through an optimization procedure applied to a measured set of

Loop-shield-loop shielding effectiveness
IEEE Transactions on Electromagnetic Compatibility, 1999The 1967 formulation by Moser of the shielding effectiveness of a metal sheet on a small loop is extended to loop-to-loop coupling. The integration of flux through the receiving loop simply adds another J/sub 0/(ka) Bessel function to the Moser integrands; the result is a monotonic variation of coupling with loop spacing, unlike the original results.

To Shield or Not to Shield: Application of Bismuth Breast Shields
American Journal of Roentgenology, 2013The purposes of this essay are to describe the effects of bismuth breast shielding on radiation exposure of the breast and posterior chest wall and to present arguments for and against the use of breast shields.Breast tissue may receive substantial radiation doses during CT examinations. Bismuth shields effectively reduce breast exposure at the expense

Shielding effect of superconducting magnetically shielded room
IEEE Transactions on Magnetics, 1997A Superconducting Magnetically Shielded Room (SMSR) has been developed. Superconducting panels are soldered to form a shielding wall of which the soldered connections have normal conduction. Therefore, the Shielding Factor (SF) of the SMSR degrades especially at low frequency, which is different from a superconducting shielded room without a normal ...

Software-Defined Network (SDN) is getting popular and increasingly deployed in both of academia and industry. As a result of which, its security issue is being magnified as a critical controversy, and some pioneering researchers have investigated the vulnerabilities of SDN to discover the feasibility of compromising SDN networks. Especially, they prove

Proceedings of the 45th annual Design Automation Conference, 2008
Security of MPSoCs is an emerging area of concern in embedded systems. Security is jeopardized by code injection attacks, which are the most common types of software attacks. Previous attempts to detect code injection in MPSoCs have been burdened with significant performance overheads.

Machine learning classification has enabled many innovative services, e.g., in medicine, biometrics, and finance. Current practices of sharing sensitive input data or classification models, however, causes privacy concerns among the users and business risk among the providers. In this work, we resolve the conflict between privacy and business interests

This chapter explores Marianne Moore’s understudied admiration for Haile Selassie, the last reigning emperor of the Ethiopia’s Solomonic dynasty. Moore’s archive includes numerous press clippings and literature—spanning four decades—concerning Selassie, the “Lion of Judah,” who became an international celebrity during the mid-twentieth century when, in
