Existence of 2 SOLS and 2 ISOLS

existence and approximate $l^{p}$ and continuous solution of nonlinear integral equations of the hammerstein and volterra types

بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی ‎‏بیان شد‎‎‏ه اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...

On the existence of certain SOLS with Holes

We consider a pair of MOLS (mutually orthogonal Latin squares) having holes, corresponding to missing sub-MOLS, which are disjoint and spanning. If the two squares are mutual transposes, we say that we have SOLS (self-orthogonal Latin squares) with holes. It is shown that a pair of SOLS with n holes of size h ≥ 2 exist if and only if n ≥ 4 and it is also shown that a pair of SOLS with n holes o...

Existence of Generalized Steiner Systems GS(2, 4, v, 2)

Generalized Steiner systems GS(2, 4, v, 2) were first discussed by Etzion and used to construct optimal constant weight codes over an alphabet of size three with minimum Hamming distance five, in which each codeword has length v and weight four. Etzion conjectured its existence for any integer v ≥ 7 and v ≡ 1 (mod 3). The conjecture has been verified for prime powers v > 7 and v ≡ 7 (mod 12) by...

ULTRAWAVES ( IST - 2001 - 35189 ) D 2 . 2 D 2 . 2 : Co existence analysis report

This document is about the “UWB co-existence analysis” to be published as an Ultrawaves deliverable D2.2. The document covers the co-existence studies between ultra wideband and other radio systems. If UWB systems will be adopted in a common use globally, or only in Europe, an inevitable consequence is that the UWB co-existence issues will have more and more significant role in the near future ...
