The reaction of MgCl(2), NiCl(2), and Na(2)(i-mnt) (i-mnt is 1,1-dicyano-thene-2,2-dithiol-ate) with 15-crown-5 (15-C-5) leads to an infinite chain polymer, {[NiMg(2)(C(4)N(2)S(2))(2)(C(10)H(20)O(5))(2)]Cl(2)}(n) or {[Mg(15-C-5)](2)[Ni(i-mnt)(2)]Cl(2)}(n), which consists of two [Mg(15-C-5)](2+) complex cations, one [Ni(i-mnt)(2)](2-) complex anion and two Cl(-) ions per formula unit. In the [Ni...

Problem statement: Santa Barbara Amorphous (SBA-15) is significant mesoporous silica with exclusive and important properties of highly ordered mesopores, hydrothermally stable and thick wall, profusely large surface area and huge pore volume which render it as promising catalyst for wide applications. However, the purely siliceous SBA-15 which lacks of acidity characteristic hinders its ideal c...

Intuitively, a complex network is robust if it keeps its basic functionality even under failure of some of its components. The study of robustness in networks is important because a thorough understanding of the behavior of certain classes of networks under failures and attacks may help to protect, for instance, communication networks like the Internet against assaults or to exploit weaknesses ...

In this lecture, we will cover amortized analysis, which is a method where we consider the average work done over an entire sequence of operations instead of just considering the worst-case cost/time for a single operation; by doing such an analysis, we can obtain tighter bounds in scenarios when expensive operations occur rarely enough that we can charge their cost to more frequent inexpensive...

Over the past decade, cloud services emerged as one of the most promising technologies in IT. Since cloud computing allows improving the quality of software and, at the same time, aims at reducing costs of operating software and hardware, more and more software is delivered as a service in the cloud. However, moving existing software applications to the cloud and making them behave as software ...

The variance of zt around its expected value E( gt ) in this particular generation is σ g(t) + σ 2 e(t). However, we usually don’t know the particular value of dt, which is assumed to be uncorrelated between generations (σ(dt, dt′) = 0), with mean 0 and variance σ d. Thus, the expected value of zt measured at a random time (e.g., the value of d is chosen at random) is μ+E( gt ) and the variance...

15.1. The First Law of Thermodynamics • Define the first law of thermodynamics. • Describe how conservation of energy relates to the first law of thermodynamics. • Identify instances of the first law of thermodynamics working in everyday situations, including biological metabolism. • Calculate changes in the internal energy of a system, after accounting for heat transfer and work done. 15.2. Th...

In the next Generation Networks like Mobile WiMAX, it is highly essential to create a market mechanism that would allow the customer to communicate with Network and negotiate a contract based on some QoS parameters like blocking probability, delay, arrival rate, spectral efficiency, resource allocation and price. However, the mechanisms, rather than technical-oriented scheme, that involve the u...
