Engel conditions in certain groups / Quek Shio Gai
No full textThis thesis is a study of certain Engel conditions. First, we will define the set
of all the X-relative left Engel elements L(G;X) and the set of all the bounded
X-relative left Engel elements L(G;X), where X is a subset of G. When X = G,
L(G;X) = L(G) and L(G;X) = L(G), where L(G) is the set of all the usual left
Engel elements and L(G) is the set of all the usual bounded left Engel elements.
Next, we de�ne the X-relative Hirsch-Plotkin radical HP(G;X) and the X-relative
Baer radical B(G;X). When X = G, HP(G;X) = HP(G) and B(G;X) = B(G)
where HP(G) is the usual Hirsch-Plotkin radical and B(G) is the usual Baer radical.
We will show that if X is a normal solvable subgroup of G, then B(G;X) = L(G;X)
and HP(G;X) = L(G;X). This is an extension of the classical results B(G) = L(G)
and HP(G) = L(G) provided that G is solvable. Next, we show that if X is
a normal subgroup of G and G satis�es the maximal condition, then L(G;X) =
HP(G;X) = B(G;X) = L(G;X), which is also an extension of the classical result
L(G) = HP(G) = B(G) = L(G). We also proved similar results when X is a
subgroup of certain linear groups.
Let G be a group and h; g 2 G. The 2-tuple (h; g) is said to be an n-Engel pair,
n � 2, if h = [h;n g]; g = [g;n h] and h 6= 1. We will show that the subgroup generated
by the 5-Engel pair (x; y) satisfying yxy = xyx and x5 = 1 is the alternating
group A5. Next, we show that if (x; y) is an n-Engel pair, xy
Multi-layer Unmanned Aerial Vehicle Networks: Modeling and Performance Analysis
No full textIn this paper, we establish a foundation for the multi-layer aerial networks (MANs), which are modeled as K layer aerial networks (ANs), where each layer has unmanned aerial vehicles (UAVs) with different densities, floating altitudes, and transmission power. To make the framework applicable for various scenarios in MAN, we consider the transmitter- and the receiver-oriented node association rules as well as the air-to-ground and air-to-air channel models, which form line of sight links with a location-dependent probability. We then newly analyze the association probability, the main link distance distribution, successful transmission probability (STP), and area spectral efficiency (ASE) of MAN. The upper bounds of the optimal densities that maximize STP and ASE are also provided. Finally, in the numerical results, we show the optimal UAV densities of each AN that maximize the ASE and the STP decrease with the altitude of the network. We also show that when the total UAV density is fixed for two layer AN, the use of single layer in higher(lower) altitude only for all UAVs can achieve better performance for low(high) total density case. Otherwise, distributing UAVs in two layers, i.e., MAN, achieves better performance.1
