Abstract The performance assessment of a 5 kWp On-Grid Mon-crystalline silicon photovoltaic( PV) solar system is the subject present paper. This PV located in Baghdad city, Al-Mansour company. observed during 2018. current system’s yearly daily averages for array yield final yield, and reference are 4.65 kWh/kWp, 4.5 5.9 respectively. yield’s energy 1613.8 kWh/kWp. year’s electrical output from...

Recently, the study of patterns in inversion sequences was initiated by Corteel–Martinez–Savage–Weselcouch and Mansour–Shattuck independently. Motivated their works a double Eulerian equidistribution due to Foata (1977), we investigate several classical statistics on restricted that are either known or conjectured be enumerated Catalan, Large Schröder, Baxter Euler numbers. One two highlights o...

Abstract Recently, Gross, Mansour and Tucker introduced the partial-dual polynomial of a ribbon graph as generating function that enumerates all partial duals by Euler genus. It is analogous to extensively studied in topological theory genus embeddings given graph. To investigate polynomial, one only needs focus on bouquets: is, graphs with exactly vertex. In this paper, we shall further show b...

The Even-Mansour (EM) encryption scheme received a lot of attention in the last couple of years due to its exceptional simplicity and tight security proofs. The original 1-round construction was naturally generalized into r-round structures with one key, two alternating keys, and completely independent keys. In this paper we describe the first key recovery attack on the one-key 3-round version ...

In this paper, we investigate the multi-user setting both in public and in secret-key cryptanalytic applications. In this setting, the adversary tries to recover keys of many users in parallel more efficiently than with classical attacks, i.e., the number of recovered keys multiplied by the time complexity to find a single key, by amortizing the cost among several users. One possible scenario i...

The article highlights the career of Professor Mansour Ali Haseeb (1910 - 1973; DKSM, Dip Bact, FRCPath, FRCP [Lond]), a pioneer worker in health, medical services, biomedical research and medical education in the Sudan. After his graduation from the Kitchener School of Medicine (renamed, Faculty of Medicine, University of Khartoum [U of K]) in 1934, he devoted his life for the development of l...

In a recent article [11], Dukes, Flanagan, Mansour and Vajnovszki present Gray codes for several families of pattern avoiding permutations. In their Gray codes two consecutive objects differ in at most four or five positions, which is not optimal. In this paper, we present a unified construction in order to refine their results (or to find other Gray codes). In particular, we obtain more restri...

Helicobacter pylori infection is chronic situation that increases the risk of development of peptic ulcer disease, mucosa-associated lymphoid tissue lymphoma (MALT), and gastric cancer. In many developing countries, such as Iran, H. pylori infect approximately 80 % of the population. Management of H. pylori infections is difficult, and relapse frequently occurs after successful eradication of t...
