The Divine Eye in Ancient Egypt and in the Midrash Interpretation of Formative Judaism.

This paper studies the “eye” as a religious phenomenon from the multiple traditions of ancient Egypt compared with rabbinic Judaism in late antiquity using a semiotic approach based upon the theories of Umberto Eco. This method was chosen because the eye is a graphic as well as a linguistic sign which both express religious concepts. Generally, the eye represented an all-seeing and omnipresent divinity. In other words, the god was reduced to an eye, whereby the form of the symbol suggests a meaning to the viewer or religious practitioner. In this manner the eye represented the whole body of a deity in Egyptian and the power of a discerning God in rabbinic texts. By focusing upon the semantic aspect of the eye metaphor in both Egyptian and rabbinic texts two religious traditions of the visually perceivable are analyzed from a semiotic perspective.

Ancient Calendars and Bolivian Modernity: Tiwanaku’s Gateway of the Sun, Arthur Posnansky, and the World Calendar Movement of the 1930s

Tourists to the archaeological site of Tiwanaku are presented with ancient calendars, of which the Gateway of the Sun is the most important, famous, and beautiful. Arthur Posnansky and other early 20th-century archaeologists claimed that its inscriptions constituted a written calendar. These claims were intimately connected to narratives of Tiwanaku as a central source of knowledge in both pre-Columbian times and the contemporary world. Posnansky presented his interpretation of Tiwanaku’s calendars as a response to the debates of the World Calendar Movement, which in the 1930s was attempting to rationalize the Gregorian calendar. In the Gateway, Posnansky found a uniquely Bolivian response to the international, North Atlantic-dominated scientific community’s search for a rational way to keep time in the world economy. Bolivian intellectuals merged their interest in the indigenous past with their concerns about the role of the modernist Bolivian state in the global system.

3CAM - A NOVEL TERNARY CONTENT ADDRESSABLE MEMORY USING THREE-VALUED LOGIC

Content Addressable Memory (CAM) is a special type of Complementary Metal-Oxide-Semiconductor (CMOS) storage element that allows for a parallel search operation on a memory stack in addition to the read and write operations yielded by a conventional SRAM storage array. In practice, it is often desirable to be able to store a “don’t care” state for faster searching operation. However, commercially available CAM chips are forced to accomplish this functionality by having to include two binary memory storage elements per CAM cell,which is a waste of precious area and power resources. This research presents a novel CAM circuit that achieves the “don’t care” functionality with a single ternary memory storage element. Using the recent development of multiple-voltage-threshold (MVT) CMOS transistors, the functionality of the proposed circuit is validated and characteristics for performance, power consumption, noise immunity, and silicon area are presented. This workpresents the following contributions to the field of CAM and ternary-valued logic:• We present a novel Simple Ternary Inverter (STI) transistor geometry scheme for achieving ternary-valued functionality in existing SOI-CMOS 0.18µm processes.• We present a novel Ternary Content Addressable Memory based on Three-Valued Logic (3CAM) as a single-storage-element CAM cell with “don’t care” functionality.• We explore the application of macro partitioning schemes to our proposed 3CAM array to observe the benefits and tradeoffs of architecture design in the context of power, delay, and area.
