Fault Diagnosability Of Regular Graphs, Mei-Mei Gu, Rong-Xia Hao, Eddie Cheng

Theory & Applications of Graphs

An interconnection network's diagnosability is an important measure of its self-diagnostic capability. In 2012, Peng et al. proposed a measure for fault diagnosis of the network, namely, the h-good-neighbor conditional diagnosability, which requires that every fault-free node has at least h fault-free neighbors. There are two well-known diagnostic models, PMC model and MM* model. The h-good-neighbor diagnosability under the PMC (resp. MM*) model of a graph G, denoted by t_h^PMC(G) (resp. t_h^MM*(G)), is the maximum value of t such that G is h-good-neighbor t-diagnosable under the PMC (resp. MM*) …

Fuzzy Filtering For Two Dimensional Images Of Mechanical Parts., Abdallah Alshnnaway, Ayman Aly

Mansoura Engineering Journal

The general idea behind the filter is to average a pixel using other pixel values from its neighborhood, but simultaneously to take care of important image structures such as edges. The main concern of the proposed filter is to distinguish between any variations of the captured digital image due to noise and due to image structure. In this work a new fuzzy filler is presented for the noise reduction of images corrupted with additive noise . The filter consists of three stages. (1) Define fuzzy sets in the input space to computes a fuzzy derivative for eight different directions (2) …

Site Tolerance Of The Rada Intein, Chase Taul, Christopher Lennon Dr

Honors College Theses

Inteins (intervening proteins) invade genes at the DNA level and splice out at the protein level. Once thought of as only a parasitic type of a mobile genetic element, recent work suggests a mutualistic relationship has formed in some cases within bacterial and archaeal hosts. After translation, a precursor protein is formed with the intein between two exteins. The intein is catalytic and can excise itself out through protein splicing. Intein insertion is biased towards the active site of the protein and is thought to cause inactivation of the host protein prior to splicing. Intein splicing is responsive to a …

Local Offenses, Brenner M. Fissell

Faculty Publications

Criminal law is generally thought to exist within two jurisdictional levels: federal and state. Neglected in the legal mind, and in legal scholarship, is the vast body of criminal law promulgated by local governments. While one should ask “what” is being criminalized by cities, towns, and villages, one should also ask “how” these offenses are written. The offense-drafting practices reflected in state criminal law have been extensively studied, but this has never been attempted for local offenses. This Article undertakes that task. After surveying a large number of local criminal codes, this Article concludes that local offenses routinely fail to …

New Secret Key Exchange Based On Recent Cryptographic Schemes., Amina Rashad, Maged Ibrahim, Zaki Nossair

Mansoura Engineering Journal

Authenticated key exchange protocols have an important role for building secure communications amongst two or more entities over the networks. Two party authenticated key exchange protocols where each pair of parties must share a secret with each other; a three-party protocol does not cause any key management problem for the parties. In this paper, an extension of two-party key exchange protocol, which is based on Diffie-Hellman key exchange. is proposed. In this protocol each user exchanges secret key with server then each user uses this secret key to exchange session key with each other. The efficiency and the security analysis …

Automating Autism: Disability, Discourse, And Artificial Intelligence, Os Keyes

The Journal of Sociotechnical Critique

As Artificial Intelligence (AI) systems shift to interact with new domains and populations, so does AI ethics: a relatively nascent subdiscipline that frequently concerns itself with questions of “fairness” and “accountability.” This fairness-centred approach has been criticized for (amongst other things) lacking the ability to address discursive, rather than distributional, injustices. In this paper I simultaneously validate these concerns, and work to correct the relative silence of both conventional and critical AI ethicists around disability, by exploring the narratives deployed by AI researchers in discussing and designing systems around autism. Demonstrating that these narratives frequently perpetuate a dangerously dehumanizing model …

St. Joseph, An Episode Of The Economic And Political History Of Florida, Part I, James Owen Knauss

Florida Historical Quarterly

No subject within the wide range of Florida’s history has stirred a greater interest than St. Joseph. Because of its quick rise to importance, its still more rapid decline, and the double tragedy of its extinction, an aspect of romance has settled upon the dead town, heightened through tradition and a haze of unreality engendered by the lack of definite records of its life. Dr. Knauss, searching out and bringing together these scanty records, gives us a light, for the first time, to penetrate that mist.

The Nine Old Wooden Forts Of St. Augustine, Part Ii, Jeannette Thurber Conner

Florida Historical Quarterly

After Drake burned the fort at St. Augustine in 1586, the settlers gave the name of San Marcos to the wooden building which took its place - Fort Number Seven. They had long wanted and asked for a fort of stone, and it would seem as if the discovery of coquina by Pedro Menendez Marques, in 1580, should have helped to bring about the realization of their wishes; but always, something came up to prevent it.

The Occupation Of Pensacola Bay, 1689-0698, Part Ii, William Edward Dunn

Florida Historical Quarterly

There were two purposes in the coming of the Spaniards to America. One was the desire for gain; the other the hope of making Christians of the natives. Unfortunately the two conflicted. The fierce desire for gold, that led to the inhuman treatment of the Indians, for a time rendered of no avail the efforts of the priests.
