Well Cathy lets take a look at your current Internet speed 56-Kbps dial up modem was the standard in the late 1990s, they were the most popular access method for personal Internet usage, but their use has declined in the developed world as broadband internet technologies such as DSL and cable internet, So currently you are using a standard that has been out of date for the last 12 years so lets look at what some of your alternatives are.
DSL
Digital subscriber line (DSL) is a family of point-to-point technologies designed to provide high-speed data transmission over traditional telephone lines.2 The reason for the limited capacity on traditional telephone circuits lies with the telephone and the switching equipment at the end offices. The actual cable in the local loop from a home or office to the telephone company end office is capable of providing much higher data transmission rates. So conversion from traditional telephone service (POTS) to DSL usually requires just changing the telephone equipment, not rewiring the local loop, which is what has made it so attractive. (Fitzgerald 344)
Fixed Wireless
The most popular types of fixed wireless are WiMax and wireless DSL, which requires a line of sight between the communicating transmitters. For this reason, wireless DSL has limited application because it requires tall buildings or towers to be effective. The most common use today is to provide Internet access to multitenant buildings such as remote office buildings, apartment buildings, and hotels. Transmitters are used to connect the building to the ISP, and DSL is used inside the building to connect to the wireless transceiver (Fitzgerald 348)

Cable Modem
One alternative to DSL is the cable modem, a digital service offered by cable television companies. Cable modem architecture is very similar to DSL with one very important difference. DSL is a point-to-point technology whereas cable modems use shared multipoint circuits. With cable modems, each user must compete with other users for the available capacity (Fitzgerald 347) Furthermore, because the cable circuit is a multipoint circuit, all messages on the circuit go to all computers on the circuit before it finally makes it to the destination computer.

As far as cost, speed and reliability goes I would recommend going with DSL. I t will be a smooth transition fro what you are currently using while giving to the increase in speed that you need to up load and download graphics with ease. Also you wont have to share your circuit with anyone else and it will be there when you need it and wont have to compete with other on the circuit. Finally you will get better security from DSL it will be harder for people with packet sniffing software to gain access to your information that you are sending and receiving, because once a again you wont be sharing that circuit with anyone else.

System Dynamic Modelling

...1. Abstract System Dynamic Modelling is an approach to frame and solve complex problems. It is widely used for policy design and analysis. System dynamics analysis is a part of Systems Theory which is used to study the dynamic behaviour of complex systems. The theory is based on acknowledgement of the fact that the inter-relations between the various components of a model, time delays between processes are as important to analyse the behaviour of a model as is the analysis of individual components.  SD models solve the problem of simultaneity (mutual causation) by updating all variables in small time increments with positive and negative feedbacks and time delays structuring the interactions and control. In this paper, we have discussed the basic methodology of the technique, and the modelling process. Then, we have discussed the applications of SDM ranging from conventional ones like project management and science and engineering to exploring the concepts of SDM in Brand management and public health issues. 2. Historical background This technique of solving problems was developed in 1950s by Prof Jay Forrester of Massachusetts Institute of Technology, during his involvement with General Electric. He developed his insights about the foundations of engineering which helped him in the creation of system dynamics. He studied the problem of instability in GE employment. In this he did hand simulations (or calculations) of the stock-flow-feedback structure of the GE plants...

Wind Tunnel

...~~~Concept of Wind-tunnel~~~ Wind tunnels date back to the 1870’s. Scientists realized it didn’t matter if an object was stationary and air was blown was over the object or if the object was moving through the air. The resultant forces over the object would be the same. The idea of blowing air over an object and determining the forces lead to the invention of wind tunnel. As the name suggests, a wind-tunnel is a cylindrical tunnel in which air is blown from one side by a huge fan at high speeds. The middle part of the tunnel is called as throat. It is the place where the test model is placed. Various sensors are attached to the test model and the data is collected in the room near it. The data collected issued to reduce the aerodynamic drag and minimize fuel consumption and also increase the speed of the cars, trucks, planes, etc. also aerodynamic properties like lift, drag, forces, moments are measured with the use of wind-tunnel. In wind-tunnel air is blown over the test model which is kept stationary at the throat. This will produce the same effect as it would be produced if the vehicle is moving at high speeds on a road. For more accurate results the tunnel is sometimes equipped with rolling road to prevent the boundary layer forming on the floor which may affect the test results. * What are wind tunnels? Just as its name suggests, a wind tunnel is a tube or tunnel that has man-made windblown through it at a certain speed. Scientists and engineers put...

Describe the Nature of Groups and Group Behavior Within Organizations

...task and maintain a steady-quality workforce by meeting members' needs. When there is no expert in the specific problem or the problem solving can be settled by a division of labor and the sharing of information, or new ideas are needed, these kinds of situations are better than handling it by individuals. Normative view, group dynamics and internal nature of group are the views of the interaction between members of a group. Firstly, normative view is to describe how to form a group and implement events. Secondly, group dynamics involve of a set of techniques such as role play, team building and training. Thirdly, through the group dynamics, it studies the internal nature of the groups. Groups are typically separated into two main categories – formal and informal. Formal groups is to complete a specific task. The members have a sense of identity and loyalty. It can be permanent or temporary. Permanent work groups are command groups in the organization structure. Task groups are temporary work groups which is to overcome the problem or form a defined task. Furthermore, it is a virtual group that the members convene and work together via networked computers and complete the same things face to face. Informal groups, goals or intentions differ to the main organizations, are formed by the employees. Friendship and interest groups are the types of informal groups. Friendship group are the members who share on or more common characteristics. Interest group are for the members working...

Introduction to Fingerprint Based Student Attendance

...robust authentication/identification security than traditional systems (eg: passwords or pass codes ,PINs , tokens). The main goal of applying biometrics to user authentication is to provide security to users and detect imposters in terms of users physiological (e.g. fingerprint, face, iris, hand) or behavioural characteristics (e.g. speech, keystroke dynamics). Owing to the unique biometric characteristic that every person possesses, utilization of the same can be done in a form of identity access management. Ever since their inception, Fingerprint based biometric authentication and verification systems have gained immense popularity and acceptance. This is primarily because of the ease of operation, installation and easy acquisition of the biometric feature, which in this case is a fingerprint. Implementing fingerprint recognition system is secure to use since the uniqueness of one’s fingerprint does not change in user’s lifetime. The popularity of mobile devices is undeniable. According to the International Data Corporation (IDC), more smartphones were sold in 2012 than desktop and laptop computers combined. This rise may be due to increasing functionality and technological advances which in turn supports greater functionality. Thus, the frequency with which smartphone owners use their devices, these devices can be used along with biometrics to provide certain advantages. The main characteristics of the proposal system are: 1) Dependency on biometric...

The Group Performance Model is also attached for your reference. 1) Problem and Rationale: Lack of Leadership by Eric of Randy – Randy has taken advantage of Eric’s poor leadership by inserting himself in as the informal leader and through his disruptive behaviors and actions .Eric has not shown to be a good team leader – he has not led the establishment of objectives, norms, or decision making processes. More importantly he has not stepped in to resolve conflicts as they occur, instead allowing them to fester and build. Eric is the formal leader, he was named as the team leader, and so has the responsibility to manage the group and its dynamics. Suggested Solution and Rationale: Eric, the team leader, needs to become a leader – he needs to go back and re-look at group dynamics and team performance models and identify what needs to be done to lead this team back on track. He specifically needs to establish the leadership role with Randy – he should have a special meeting with him to establish their roles and position on the team, encourage Randy to share his brilliant ideas, and ask how he (Eric) as the team...

Mgmt Everest

...the designated ‘Management 1001’ course requirements, and the assignment of members to groups, each group undertook the Everest Simulation – a teamwork and leadership challenge requiring groups to ascent a virtual Mount Everest. Drawing upon a range of fundamental organisational and managerial concepts and coupled with frequent challenges, the simulation effectively replicated a dynamic and teamwork based organisational environment. The simulation seeks to test interpersonal relationships and group dynamics by creating dissonance on both an individual and group level, as groups and group members strive to achieve both individual and group goals. This report will critically analyse the very processes used to undertake the Everest Simulation, along with results, focusing on the three concepts of ‘Communication’, ‘Groups and Teams’ and ‘Leadership’. These are of critical importance to forming an analysis of not only the simulation itself, but also a broader organisational and managerial situation and the correlation between managerial theory and practice and the Everest Simulation. The transition in dynamics within the group between the different simulations, and the solving of numerous challenges corresponds to the improvement in our results of the simulation. Moreover, this transition and triumph also elucidates the practicality of managerial theories associated with ‘communication’, ‘groups and teams’ and ‘leadership’ and their applicability to not only the Everest Simulation, my...

An Iterated Dynasearch Algorithm for the Single-Machine Total Weighted Tardiness Scheduling Problem

...Congram@paconsulting.com • C.N.Potts@maths.soton.ac.uk • S.Velde@fac.fbk.eur.nl Richard K. Congram • Chris N. Potts • Steef L. van de Velde T his paper introduces a new neighborhood search technique, called dynasearch, that uses dynamic programming to search an exponential size neighborhood in polynomial time. While traditional local search algorithms make a single move at each iteration, dynasearch allows a series of moves to be performed. The aim is for the lookahead capabilities of dynasearch to prevent the search from being attracted to poor local optima. We evaluate dynasearch by applying it to the problem of scheduling jobs on a single machine to minimize the total weighted tardiness of the jobs. Dynasearch is more effective than traditional first-improve or best-improve descent in our computational tests. Furthermore, this superiority is much greater for starting solutions close to previous local minima. Computational results also show that an iterated dynasearch algorithm in which descents are performed a few random moves away from previous local minima is superior to other known local search procedures for the total weighted tardiness scheduling problem. (Production Scheduling: Single Machine, Sequencing; Analysis of Algorithms; Dynamic Programming ) 1. A descent or iterative improvement algorithm is a simple and practical type of local search method for obtaining near-optimal solutions for a wide variety of NP-hard...

Individual Reflection on Team Experience

...Introduction: Individual Reflection on Team Experience Today in many industries and organizations group/team work is a tool for effective achievement of organizational goals. Understanding the way groups develop and how they impact organizational success is important to the effective use of groups in organizations. One of the most common models to describe how groups develop was described by Tuckman. Tuckman studied group development as it was seen in group therapy. This was then extrapolated to involve the development of all groups and teams that exist in areas such as those seen in organizations. In 1966, Tucker proposed that group development progressed through four identifiable stages which were named forming, storming, norming and performing. The Tuckman model for the stages of group development is one of the most cited models in the business world. Over the years there were other studies that also agreed that groups go through stages and they had identified that there appeared to be an “ending” stage as well. In 1977 Tuckman with Jensen reviewed who the stages of group development had evolved over the years since his first proposal of the stages of group development and in response to other studies they added a final stage of group development which the called adjourning (Tuckman & Jensen, 1977). The adjourning stage will not be reviewed in this paper since there was no real adjourning stage with this group. Another model for group development is the punctuated equilibrium...

Aircraft Control Systems

...Aircraft Flight Control System Name: Institutional Affiliation Aircraft Flight Control System Description of the system; functional and schematic diagrams According to the Federal Aviation Administration, an aircraft control system is assemblage of mechanical and electronic equipment that permits a plane to be flown with excellent accuracy and steadfastness. A control system mainly constitutes cockpit controls, sensors, actuators which may be hydraulic, mechanical or electrical and computers. With improvement in technology, aircraft flight controls vary depending on the type of plane since planes with different feature and sizes have been introduced in the market thus have to be fit with flight control systems that match their capacity. However, the most basic flight control system designs are mechanical and are characterized with the early aircrafts. According to Garg et al (2013, p.60),they involve collective use of different mechanical parts which include rods, cables, pulleys and chains in some designs which play a significant role in transferring forces of flight deck controls to the control surfaces. Though new flight control models have been introduced with advancement in technology, application of mechanical flight controls still continues to date especially in small general and sport classification aircrafts especially where aerodynamic forces are not extreme. Illustration of mechanical aircraft control system (Garg et al, 2013, p.61) Aircraft control systems are group...
