We concentrate on typical pedestrian speeds of 3 Km/h for users' mobility concern. In order to describe the mobility of the mobile devices, we need to define the contact time between users $k_i$ $\&$ $k_j$. It is the time taken by two mobile nodes to meet again from the last time ($t_0$) within the range of each other and denoted by $\textit{ICT}_{i,j}$, when they were going out of the range from each other, i.e., $ICT_{i,j} = \mathop {\min } \limits_t \left\{ {\left( {t - {t_0}} \right):\left\| {{L_i}\left( t \right) - {L_j}\left( t \right)} \right\| \le R_{i,j},t > {t_0}}, L > 0 \right\}$, where $L_i(t)$ and $L_j(t)$ are the locations of the users $k_i$ and $k_j$ at time $t$, respectively, $R_{i,j}$ describes the range of transmission between $k_i$ $\&$ $k_j$, and $\left\| \bullet \right\|$ is the distance measured between the corresponding nodes. $\textit{ICT}_{i,j}$ is a time duration, which is random variable and is assumed to be independent of time. …show more content…
Therefore, the contact rate is different for each device, and is Poisson distributed with the mean arrival rate of $\mathchar'26\mkern-10mu\lambda_i$. Since a series of Poisson processes are modeled and are able to maximize the content transmission at given time duration. Therefore, by defining the contact rate ${\mathchar'26\mkern-10mu\lambda _{i,j}}$, mobile devices $k_i$ $\&$ $k_j$ can make D2D communication pair. In each contact, the devices can send the data to each other by the D2D communications, if the base station assigns some cellular spectrum resources of $cu$ towards D2D pair
The Lithium Nickel Manganese oxide battery is still in its experimental stages. It consists of a 25% nickel substituted in a LiMn2O4 spinel. This is because Manganese will have 4 electrons in its valence shell which will avoid the Jahn-Teller distortion caused due to the Mn3+. Due to the oxidation or reduction of Nickel ions which leads to the transfer of electrons which corresponds to electric current. LiNi0.5Mn1.5O4 takes shape in two conceivable crystallographic structures concurring the cationic sub lattice: the face-focused spinel (S.G. Fd3m) named as "cluttered spinel" furthermore, the straightforward cubic stage (S.G. P4332) named as "requested spinel". This addition allows
In order to study the tendencies of the primary and secondary coils as they transfer energy through inductive coupling, a system that can aptly demonstrate the process is needed.
Our purpose in this lab was to create four solutions of the same components and different concentration. I found the concentration in Molarity (mol/liter). I would dilute a solution to create new solutions, using the formula M1xV1=M2xV2 where M=molarity and V=volume. In this lab, there were four solutions, Solution A, Solution B, Solution C, and Solution D. The solute or substance that dissolves was sugar and the solvent or substance that the solute dissolves in was water. For Solution A, I weighed 3.42 g sugar and diluted to 100 mL to get a concentration of 0.10 M and the color of bright red. For Solution B, I weighed 0.342 g sugar and diluted to 100 mL to get a concentration of 0.010 M and the color of pink. For Solution C, I measured 10
Next, save the excel document with the extensions, '.xlsx' and 'csv'. When the saved 'xlsx' file is loaded into ArcMap, the attributes for data type 'text' has a length of 255, with allowable null values. The numeric data type 'double' has been populated with the precision as 15 and the scale as 6. It allows null values. The data type, 'date' is populated correctly and allows null value.
In that case, there must be no systematic effect due the monochromatic $\gamma$ selection criterion.
to $0$, $R$ initially decreases from $\infty$ to $\sqrt{2 a_{0}}$ at $r= \sqrt{a_{0}}$ so will increase once
The goal of this lab was to expand and centralize our infrastructure by adding a Windows Server 2012 VM and configuring it with a number of key services. Some of the services that we deployed on the Windows 2012 VM had previously been configured on other machines, namely the RHEL VM from Lab 2. We began by installing and configuring the server itself, ensuring that we provided it with ample memory and processing power. Next, we configured DHCP, disabling the DHCP service running on our RHEL VM. We then continued by installing Active Directory and DNS on the Windows 2012 VM, disabling the DNS server running on the RHEL VM in the process. The DNS server on RHEL would later be reactivated as a secondary (slave) server. We then proceeded to set up monitoring for both DHCP and DNS. This monitoring was configured locally on the Windows 2012 VM using the Performance Monitoring utility, and also remotely via OpsView. Finally, we installed Microsoft Baseline Security Analyzer on the Windows VM. This was the first lab where it felt like we
Lab one introduces the basic concepts and processes of remote sensing and gives a better understanding of multiband images, color compositing, and contrast enhancement. The following were the objectives for the lab to help introduce these concepts and processes:

Usage of mobile phone to connect to social media is growing all over the world. Nowadays smartphones come with numerous health-consciousness apps, too. This study is to find out users’ preference between networking and health while choosing mobile phone.
Providing an internet access to passengers with high quality of service (QoS) is a key role in attracting more travellers [3]. Wireless communication systems to provide internet access for HSR are facing a lot of challenges such as, time varying and frequency selective fading due to multipath propagation and Doppler shift effect [4], a high penetration loss of 10-40 dB depending on the type of train and the angle of incidence resulting in spotty coverage and dropped calls [5], frequent handover due to the train high motion velocity will result in an increase in the drop off rates, degrading the overall system throughput also group handover caused by the simultaneous handover where hundreds of devices in the same train will request to handoff at the same time, causing a huge burden at the base station (BS) in terms of processing and resources. Moreover, an HSR propagation channel includes multiple terrains and scenarios such as urban, suburban, rural, plains, viaduct, tunnels, cuttings and stations [6], this variety found to cause a deep fade so we need to be familiar with those propagation conditions and channel fading of HSR to achieve high data
Under high traffic conditions, this works very well, and backpressure is able to fully utilize the available network resources in a highly dynamic fashion. Under low traffic conditions, however, because many other nodes may also have a small or 0 queue size, there is inefficiency in terms of an increase in delay, as packets may loop or take a long time to make their way to the destination. This is particularly of concern in intermittent encounter-based mobile networks which are already delay-limited due to the sparse and highly dynamic network connectivity. Such networks have proposed the use of redundant transmissions to improve delay, which do not work well when the traffic load is high.
