We give a complete solution for the existence problem of group divisible designs (or PBIBDs) with blocks of size k = 3, four groups of size (n, n, n, 1), and any two indices (λ1, λ2). Moreover, we introduce a construction of infinitely many group divisible designs with t groups of size n and one group of size 1. The construction technique utilizes our main result, together with some other known...

We investigate the spectrum for {4}-GDDs of type g u m 1. We determine, for each admissible pair (g, u) (with some exceptions), the maximum and minimum values of m for which a {4}-GDD of type g u m 1 exists.

This study aims to evaluate the correlation among growing degree-days (GDD), canopy height (CH), and leaf area index (LAI) for Guinea grass irrigated, considering different combinations of nitrogen boron rates cycles regrowth. The experiment was carried out from August/2017 August/2018 in a field experiment, climate region is classified as subtropical. A randomized block design arranged factori...

In this paper, we investigate the existence of a super-simple (4, 5)-GDD of type gu and show that such a design exists if and only if u ≥ 4, g(u − 2) ≥ 10, g(u − 1) ≡ 0 (mod 3) and u(u− 1)g2 ≡ 0 (mod 12). © 2009 Elsevier B.V. All rights reserved.

Broomrapes (Phelipanche spp. and Orobanche spp.) are holoparasitic plants that cause tremendous losses of agricultural crops worldwide. Broomrape control is extremely difficult and only amino acid biosynthesis-inhibiting herbicides present an acceptable control level. It is expected that broomrape resistance to these herbicides is not long in coming. Our objective was to develop a broomrape con...

In many diagnosis-and-repair domains, diagnostic reasoning cannot be abstracted from repair actions, nor from actions necessary to obtain diagnostic information. In general, in exploratory-corrective domains an agent has to interleave exploratory activity with activity aimed at achieving its goals. In TraumAID 2.0, a consultation system for multiple trauma management, we implement a reasoning f...

In this paper, we present several new attacks on multiple encryption block ciphers based on the meet-in-the-middle attack. In the first attack (GDD-MTM), we guess a certain number of secret key bits and apply the meet-in-the-middle attack on multiple ciphertexts. The second attack (TMTO-MTM) is derived from applying the time-memory trade-off attack to the meet-in-the-middle attack on a single c...

در این پژوهش 20 هیبرید ذرت دانه ای داخلی و خارجی از پنج گروه مختلف رسیدگی در دو فصل زراعی (1386 و 1387) در اسلام آباد کرمانشاه از نظر نیاز واحدهای گرمایی مورد مطالعه قرار گرفتند. به منظور ایجاد محیط های مختلف و امکان برآورد نیاز حرارتی هر یک از گروه ها، چهار تاریخ کاشت (اول اردیبهشت، 10 اردیبهشت، 25 اردیبهشت و 10 خرداد) در نظر گرفته شد. نتایج حاصل نشان داد که بر اساس نیاز حرارتی تا گلدهی، هر دو...
